For the last four or five years of his life he was in the habit of lecturing at St Andrews upon the early Greek Philosophy; his lectures were care- fully written down before delivery, in many cases re-written, and throughout diligently revised. The repeated shocks of illness which, for some years be- fore his death, gradually undermined his physical powers, probably rendered his treatment of the subject less perfect than it might otherwise have been, both as to extent in general and elaboration in detail. Nevertheless it is believed that .these lectures, frag- mentary as they are, contain enough of what is ori- ginal and valuable to justify their publication. They will assuredly not make his memory less dear to all who knew and loved him living; they may possibly help to make it dear to all who love philosophy. * This " Introductory Notice " (written by Professor E. L. Lush- ington, LL.D.) was prefixed to the First Volume of Professor Fer- rier's 4 Lectures on the Early Greek Philosophy, and other Philo- sophical Remains,' in two volumes, 1866, and is here reprinted.viii INTRODUCTORY NOTICE. James Frederick Ferrier, son of John Ferrier, W.S., grandson of James Ferrier, an intimate friend of Sir Walter Scott, was born in Edinburgh, June 16, 1808. His mother, Margaret, was sister of Professor John Wilson; his aunt, Susan Ferrier, honoured by the high praise and the friendship of Scott, was the authoress of ' Marriage/ ' Destiny/ and ' The Inheri- tance.' He received his early education in the manse of Kuthwell, Dumfriesshire, where he lived in the family of the Eev. Dr Duncan. Here first was awakened in his mind the lively interest and affec- tion which he never lost for Virgil, Ovid, and the Latin poets in general: he often spoke in later life of the new source of delight then opened to him in these authors. He also retained through after years a warm attachment both to his earliest place of instruction and to the two sons of his earli- est teacher. He studied later at the Edinburgh High School, and under Dr Burney at Greenwich. He attended Edinburgh University for sessions 1825-26 and 1826-27. He went as a fellow-com- moner to Magdalen College, Oxford, where he took the degree of B.A. in 1831; and became an advo- cate at Edinburgh in 1832. Of his pursuits for the next five or six years there is little direct evidence, but to this period belongs mainly the foundation of his strong passion for metaphysical research. It was probably the desire of studying more effectively the German masters of speculative thought that led him to spend several months of the year 1834 at Heidelberg.INTRODUCTORY NOTICE. ix He had early selected this pursuit as the most attrac- tive and congenial to his powers; and as far as his devotion to it may have needed for its full growth sympathy and encouragement from another mind, such nourishment was amply supplied by his intimacy with Sir William Hamilton. This intimacy, com- mencing in 1831, ripened into a warm friendship, and continued thoroughly cordial and affectionate, both in agreement and in difference on philosophical questions. In one of his early essays Ferrier ex- presses his ardent admiration of this great teacher (see vol. ii. p. 300), and in a later treatise, principally directed against some of Sir William Hamilton's posi- tions, he speaks thus of him: " He has taught those who study him to think, and he must stand the con- sequence, whether they think in unison with himself or not. We conceive, however, that even those who differ from him most would readily own that to his in- structive disquisitions they were indebted for at least half of all they know of philosophy." A tribute of loving reverence to Hamilton's memory, written soon after his death, will be found in vol. i. pp. 488-90. The silent workings of home influences had tended not the less surely to arouse and widen his intellectual sympathies. Having relations on both sides so highly gifted with literary ability, it is not surprising that Mr Ferrier should have combined with his meta- physical predilections a powerful and at the same time discriminating interest in all varieties of mental culture. Letters still preserved show how frank andX INTRODUCTORY NOTICE. cordial was the intercourse, which lasted till her death in 1854, between him and his aunt, Susan Terrier. It would be superfluous to enlarge upon the warm admiration which he always felt and avowed for his uncle, John Wilson, whose son-in-law he became in 1837, and whose literary remains he was busily en- gaged in editing during the years 1856, 1857, and 1858. He used to express himself, speaking of Wil- son, in some such terms as these—" I find, well as I knew him, that I can hardly even now bring up to myself a real picture of what he was in his brightest moods, far less could I hope to communicate the truth to others who had not known him." His uncle's house presented many opportunities to Mr Ferrier of mixing in society that included names of high political and literary eminence. From this conversation the seed that fell upon the youthful mind of such a listener would bring forth rich fruit of observation and reflection in after hours. He used to describe a meeting in the summer of 1825, when he saw together at Elleray, Wilson's residence near the Lake of Windermere, Scott, Wordsworth, and Canning, as among the most radiant memories of his life. A darker association was to colour his latest remembrance of the great Novelist, not many years after this date. " He used to refer with emo- tion to one sad occasion when he came immediately in contact with the author of 'Waverley.' It was on that gloomy voyage when the suffering man was conveyed to Leith from London, on his return fromINTRODUCTORY NOTICE. xi his ill-fated foreign journey. Mr Ferrier was also a passenger, and scarcely dared to look on the almost unconscious form of one whose genius he so warmly admired." * It may be there are those who will in coming years speak to their children of similar feel- ings awakened in themselves, as they watched a feeble frame, whose worn features revealed, amid the light of piercing intellect, acute suffering held down by heroic endurance, in the quiet town of St Andrews. To philosophy he ever gave his first and unwaver- ing devotion; he doubtless felt himself, and it will probably be allowed by discerning judges, that the genuine interest which he maintained to the last in literature not technically or nominally philosophical, made him in no way less able to preserve his primary allegiance unalloyed. He read works of imagination with deep imaginative sympathy: a strong poetical element in his own nature responded vividly to the subtlest touch of all true poetry. His numerous con- tributions to ' Blackwood's Magazine' attest to what extent the various sides of literature possessed attrac- tions for him. For special mention may be selected, —The Translation of Tieck's Pietro d'Abano, in August 1839; of Deinhardstein's Picture of Danae, September 1841; The Tittle-Tattle of a Philosopher, December 1841; and the Keview of Miss Barrett's Poems, November 1844. To some among the many readers whose admiration for Mrs Browning's genius * Quoted from Principal Forbes's address to the Students of St Andrews, November 1864.xii INTRODUCTORY NOTICE. is deep and sincere, it may not be without interest to peruse an extract from this article, written at a time when her extraordinary powers were far less generally recognised than now:— "If the poetess does not always command our unqualified approbation, we are at all times disposed to bend in reverence before the deep-hearted and highly accomplished woman—a woman whose powers appear to us to extend over a wider and profounder range of thought and feeling than ever before fell within the intellectual compass of any of the softer sex. . If we might venture to divine this lady's moral and intellectual character from the general tone of her writings, we should say, that never did woman's mind dwell more habitually among the thoughts of a solemn experience — never was woman's genius impressed more profoundly with the earnestness of life, or sanctified more purely by the overshadow- ing awfulness of death. She aspires to write as she has lived; and certainly her poetry opens up many glimpses into the history of a pure and profound heart which has felt and suffered much. At the same time, a reflective cast of intellect lifts her feelings into a higher and calmer region than that of ordinary sorrow. There are certain delicate and felicitous peculiarities in the constitution of her sensibilities, which frequently impart a rare and subtle originality to emotions which are as old, and as widely diffused, as the primeval curse. The spirit of her poetry ap- pears to us to be eminently religious; not becauseINTRODUCTORY NOTICE. xiii we think her very successful when she deals directly with the mysteries of divine truth, but because she makes us feel, even when handling the least sacred subjects, that we are in the presence of a heart which, in its purity, sees God. In the writings of such a woman, there must be much which is cal- culated to be a blessing and a benefit to mankind. If her genius always found a suitable exponent in her style, she would stand unrivalled, we think, among the poetesses of England. . . . " If any of our remarks have been over-harsh, we most gladly qualify them by saying that, in our humble opinion, Miss Barrett's poetical merits infi- nitely outweigh her defects. Her genius is profound, unsullied, and without a flaw. The imperfections of her manner are mere superficial blots which a little labour might remove. Were the blemishes of her style tenfold more numerous than they are, we should still revere this poetess as one of the noblest of her sex; for her works have impressed us with the con- viction, that powers such as she possesses are not merely the gifts or accomplishments of a highly in- tellectual woman, but that they are closely inter- twined with all that is purest and loveliest in good- ness and in truth." In 1851, when Sir Edward Bulwer Lytton, now Lord Lytton, was preparing to republish his transla- tion of Schiller's Ballads, he frequently corresponded with Mr Ferrier, whose critical judgment and skill in detecting the finer shades of meaning in the orig-xiv INTRODUCTORY NOTICE. inal German he highly valued, as his dedication to the poems amply testifies. Mr Ferrier's earliest public essay in metaphysical science consists of the papers, here republished, which, under the title " An Introduction to the Philosophy of Consciousness," he contributed to 'Blackwood's Magazine' in 1838 and 1839, "undertaking," as Sir William Hamilton said, "the solution of problems hitherto unattempted in the humbler speculation of this country." For some years after this he wrote occasional articles in that Magazine, and must have become in the meantime well known to many per- sons in Edinburgh as one who delighted in exploring questions that task powers of abstraction and subtle thought. In 1842 he was appointed Professor of Civil History in the University, an office at that time neither very laborious nor lucrative, and gen- erally looked upon as likely to be a stepping-stone to some more important professorship. In session 1844-5, during Sir William Hamilton's severe illness, Mr Ferrier acted as his substitute, and taught the class of logic and metaphysics for some time; his zeal and success in the discharge of this task are warmly acknowledged by Sir William in a testimo- nial given to Mr Ferrier when applying for a chair in another university. In 1845 he was elected Pro- fessor of Moral Philosophy and Political Economy at St Andrews, and held that office till his death. On two occasions he sought to obtain an appoint- ment in Edinburgh; in 1852, on the resignationINTRODUCTORY NOTICE. XV of his uncle, Professor Wilson, he became candi- date for the professorship of Moral Philosophy, and in 1856 he sought to succeed to the chair of Logic and Metaphysics vacated by the death of Sir Wil- liam Hamilton. On both occasions the voice of the electors determined otherwise; his name and his immediate influence as a teacher are destined to be pre-eminently associated with St Andrews. While holding this office Mr Terrier published, in 1848, a pamphlet (anonymous), entitled ' Observa- tions on Church and State, suggested by the Duke of Argyll's Essay on the Ecclesiastical History of Scotland;' and in 1858 a ' Letter to the Eight Hon- ourable the Lord Advocate of Scotland on the Neces- sity of a Change in the Patronage of the University of Edinburgh.' He also continued to write occasional articles in ' Blackwood's Magazine,' which prove that his professional studies, ardently as they were pur- sued, did not entirely monopolise his attention. In the earlier years of his professorship, his lec- tures seem to have been more devoted to setting forth and criticising the various schemes of mental and moral philosophy which have arisen since the time of Descartes and Locke, than to exhibiting in systematic order new views of his own, except in so far as this cannot be avoided in commenting on the doctrines of others. He wrote of his professional labours to a friend:—" I cancel and re-write about a third of my lectures every year; a circumstance which, if it proves that my lectures were bad to beginxvi INTRODUCTORY NOTICE. with, also proves that they have some chance of growing better." For two or three years before he published his ' Institutes of Metaphysic' (in 1854), he had regularly developed to his hearers, proposition by proposition, the theory contained in that work. On this theory he frequently corresponded with his friends. It may fairly be presumed that in address- ing a subtle metaphysical thinker, capable among few other Englishmen of estimating what had been done for philosophy by Kant, and better acquainted than most with the later labours of Kant's successors, Mr Ferrier would especially aim at aiding the im- pression which his own new speculations might produce, by distinctness and forcible lucidity in an- nouncing them. For this reason there is inserted at a later page in this volume a letter * written to Mr De Quincey, who had for some time regarded Fer- rier as the metaphysician of highest promise among his contemporaries in England or Scotland, and had expressed his conviction in a warmly eulogistic tes- timonial, which the letter gratefully acknowledges. Letters to various other friends remain, written about the same time on the same subject; but none more characteristic, or exhibiting in clearer outlines the nucleus of his theory. This work reached a second edition in 1856. It called forth various criticisms, some of which he noticed in a pamphlet, entitled ' Scottish Philosophy, * This is now transferred to the end of the third edition of the 4 Institutes of Metaphysic.'INTRODUCTORY NOTICE. xvii the Old and the New/ published in 1856. When he composed this essay he believed that his views had been by many misunderstood, by some unfairly rep- resented; and to this circumstance he partly attri- buted his failure to obtain the Chair of Logic and Metaphysics in Edinburgh. In some passages a warmth of feeling and expression was perceptible, not perhaps surprising in one who felt convinced that injurious and unwarranted misconceptions of his meaning had prevailed against him, but not alto- gether in harmony with the calmness best fitted to the treatment of philosophical questions, a quality which few thinkers could value more highly than Mr Ferrier himself.* It has been accordingly judged unnecessary to reproduce the whole of this pamphlet; anything that could needlessly give pain the Editors have thought it right to omit, while they hope that nothing essential or possessing significance for the vindication of the Author's system has disappeared from the remodelled form in which it is now pre- sented to the reader, as ' Appendix to the Institutes of Metaphysic/ * A characteristic extract from a letter to a friend may illustrate his deliberate judgment on this head. He wrote in 1851 :—"One thing I would recommend, not to be too sharp in your criticism of others. No one has committed this fault oftener, or is more dis- posed to commit it, than myself; but I am certain that it is not pleasing to the reader, and after an interval it is displeasing to oneself. In the heat and hurry of writing a lecture I often hit a brother philosopher, as I think, cleverly enough, but on coming to it coolly next year I very seldom repeat the passage. I am not, however, charging you with this fault, but merely putting you on your guard against it." bxviii INTRODUCTORY NOTICE. His labours as a professor were prompted by un- sparing energy; they were rewarded by one of the truest evidences of merit, the devoted sympathy and attachment of his pupils. To stimulate their minds to philosophic thought, to lead them to insight rather than tenacity of conviction, and empower them to think for themselves,—this, as the steady principle of his endeavours, is repeatedly set forth in his lectures, and undeviatingly ruled his practice. In all matters of College business his sound judgment and vigorous good sense were acknowledged and looked up to by his colleagues. His students felt sure there was not one among their professors to whose generous consid- eration of their feelings they might more confidently trust, or whose resolute assertion of all that was due to his own office they must more implicitly respect. They revered him as a guide to truth and wisdom, they loved him as an elder friend and fellow-labourer. His devotion to contemplative study was so per- sistent and absorbing, that he was seldom induced to leave his home in St Andrews for excursions to any distant quarters. His friends both in Scotland and England had often to regret the rareness of the visits which he paid them, not only on their own account, but, as they believed, for his sake also. For they could not repress within them the strong persuasion that the intensity of his solitary labours in search of truth was wearing him out, and that whenever he could be induced to intermit the restless mental ex- ercise, usually carried on far into the morning hours,INTRODUCTORY NOTICE. xix such relaxation must prove beneficial to his general health. But for him philosophy had deeper charms than for most even of laborious and meditative in- quirers. The "difficult air" which surrounds the top of the mountain of speculation, exhausting to common travellers in that high region, was to him as the daily breath of life. Those among his acquaint- ance for whom such abstruser pursuits had no attrac- tion, could not but feel and acknowledge the large- ness of mind and heart which enlivened his social intercourse, which sought for no display, but mani- fested itself in the readiness with which he entered alike into the common business and recreation of everyday life, and into all general topics of rational interest. The most devoted of all students, he was the last man to whom any one who knew him, or even casually met him, could have thought of apply- ing the description of " pedant." In mixed company, his graceful courtesy, his rich and genial humour, and the fine unstrained benignity which, being heart- deep, inspired his whole manner, secured general ad- miration and goodwill. There was hardly a social meeting at St Andrews at which his presence, ex- pected or unexpected, would not have been welcomed with genuine gladness; nor could any subject be mooted on which his views, however unobtrusively expressed, would not have been listened to with re- spectful attention. His general appearance, and latterly his disincli- nation to any but the most moderate exercise, sug-XX INTRODUCTORY NOTICE. gested the impression that his health was far from robust, but it seemed mostly to preserve an equable tenor till the first violent seizure which prostrated his strength, so that it never could be fully restored. This was an attack of angina pectoris, which came upon him (with nothing obvious to account for it) early in November 1861. For several hours he was considered to be in imminent danger, but the vital power was not entirely shattered; a temporary re- covery took place, but the weakness which followed prevented him from continuing his lectures till some weeks later. At that time the largest apartment in his house was fitted up as a lecture-room, where his students met, it being judged unsafe for him to un- dergo the fatigue of moving daily as far as the Col- lege class-room. The date of several of his lectures on Greek philosophy shows how little he relaxed his exertions for the instruction of his class, notwithstand- ing this shock to his physical powers. And indeed those who conversed with him after this date on his favourite topics were aware that his subtlety and penetrating energy of thought were as vivid as ever. But it could hardly escape their notice that bodily infirmity was fast gaining ground upon him; his power of walking became less and less; a very short distance at times seemed to be too much for him; the ascent of a staircase would make him pant and appear overcome almost to exhaustion. Tendencies to asthma had long been observed; dropsical symptoms and affection of the heart assumed a threatening form.INTRODUCTORY NOTICE. xxi On the whole, after this first formidable attack it began to be manifest that life was but a continued unequal struggle against manifold besieging forces. From this time, though he often spoke hopefully of his state of health, he must have anticipated as far from improbable that any day or hour might bring a rapidly fatal onset of his malady. Towards his friends, dur- ing this interval, all that was sweetest in his dispo- sition seemed to gain strength and expansion from the near shadow of death. He spoke of death with entire fearlessness, and though this was nothing new to those who knew him best, it impressed their minds at this time more vividly than ever. The less they dared to hope for his life being prolonged, the more their love and regard were deepened by his tender thoughtfulness for others, and the kindliness which annihilated all absorbing concern for himself. In many little characteristic touches of humour, frank- ness, beneficence, beautiful gratitude for any slight help or attention, his truest and best nature seemed to come out all the more freely; he grew, as it were, more and more entirely himself indeed. If ever a man was true to philosophy, or a man's philosophy true to him, it was so with Ferrier during all the time when he looked death in the face and possessed his soul in patience. As the light of all his friend- ships shone ever with steadier brightness, past ani- mosities sank out of sight. At a time when he was too ill to see any visitor, the card was brought to him of a former opponent on philosophical questions,xxii INTRODUCTORY NOTICE. whose criticisms of his views had been regarded by him as unjust, and had provoked some warmth of language in his reply to them, but who now called to inquire after his health. He was perceptibly touched by this mark of friendly feeling, and ex- claimed, " That must be a good fellow !" Twice in the course of the year 1863, in January and October, an assault of illness more than usually threatening had come on. He had, in the June of this year, travelled to London, to examine in phil- osophy the students of the London University, and had purposed doing so again in October; but after this attack it was obviously impossible. On the 31st of October, Dr Christison was consulted about his state, and pronounced his case to be past hope of remedy. He opened his class on the 11th of November in his own house, but during this month was generally confined to bed. On the 8th of December he was at- tacked by congestion of the brain, and never lectured again. His class was conducted by Mr Ehoades, then Warden of the recently-founded College Hall, who, as many others among his colleagues would have been ready to do, willingly undertook the mel- ancholy task of officiating for so beloved and hon- oured a friend. After this all severe study and men- tal exertion were forbidden. He became gradually weaker, with glimpses now and then of transitory improvement. So in unfailing courage and resigna- tion, not unwilling to hope for longer respite, but al- ways prepared to die, he placidly, reverently, awaitedINTRODUCTORY NOTICE. xxiii the close, tended by the watchful care of his devoted wife and children. He breathed his last about eleven o'clock on the morning of Saturday the 11th of June 1864; his mortal remains were followed to the grave by many to whom his memory is dear, and rest near those of his father and grandfather in St Cuthbert's Church- yard in Edinburgh. "What Ferrier was, is more surely treasured in the hearts of those who knew him than it can be livingly communicated in language to others: nevertheless it appears due to truth to record the utterances of some friends, who, from their constant and familiar inter- course, had the best means of knowing and esti- mating him aright. Contributions towards this end have been asked from a few, and granted with ready kindness. Principal Tulloch, of St Mary's College, St Andrews, writes thus:— " By the time I came to St Andrews (1854) Pro- fessor Ferrier had reached the maturity of his powers, if not of his reputation. The f Institutes of Meta- physic' were just published, and I had read the volume with great admiration, fascinated particularly by the boldness and brilliant subtlety of its specula- tions. We soon formed a fast friendship; and as for some years we both remained at St Andrews, in sum- mer as well as winter, we were in the habit of con- stantly meeting together. His interest ill intellectual discussions was unceasing; his love of books, and hisxxiv INTRODUCTORY NOTICE. appreciation of literature in all its higher forms, as fresh as that of a youth in the first flush of his stud- ies, and a more delightful companion therefore could not be imagined. There are those who along with me, I am sure, can never forget the pleasantness of those early years in St Andrews, when our friend was still in vigorous health, and eager to encounter any disputant in his favourite subjects. The playful humour which he mingled with the most abstract discussions, the heights of metaphysical argument which he scaled so easily, and in the rare atmos- phere of which he was able to sustain himself longer than any other disputant I ever knew, his genial and frank bearing, and the welcome and fairness of spirit with which he always met opposition, gave a great attraction to his conversation. " Life in his study was Professor Terrier's charac- teristic life. There have been, I daresay, even in our time, harder students than he was; but there could scarcely be any one who was more habitually a stu- dent, who lived more amongst books, and took a more special and constant delight in intercourse with them. In his very extensive but choice library he knew every book by head-mark, as he would say, and could lay his hands upon the desired volume at once. It was a great pleasure to him to bring to the light from an obscure corner some comparatively unknown English speculator of whom the Univer- sity Library knew nothing. " During the summer of 1863, the last of which heINTRODUCTORY NOTICE. XXV was to see the close, I was w7ith him almost every day. At this time I was myself laid aside from sys- tematic work of any kind, while his obviously failing health and incapacity to walk any distance without suffering invited companionship. His intellectual interest was as keen as ever, but the hope of doing much more was fast dying out. He reflected with satisfaction that he had completed his lectures on the Early Greek Philosophy, and he would fain have been spared for a renewed study of Plato, and a fresh and extended treatment of the Platonic Philosophy. He felt this to be no longer possible; but his mind nat- urally lingered round his favourite subject, and we spent the summer in reading together some of the Dialogues in which he formerly delighted, and had carefully pencilled with his notes. He took it into his head also to read through Yirgil, and I used some- times to join him in the evenings which he devoted to this purpose. The companionship was a great pleasure to me, and seemed in some degree to relieve the tedium of his bodily languor. The strength and patience of his character, and buoyant energy and varied activity of his mind, were never more con- spicuous. We had many earnest conversations, too, about more solemn matters; for it is needless to say that a reason so inquisitive and reflective as Pro- fessor Perrier's had pondered much on the subject of religion. He was unable to feel much interest in any of its popular forms, but he had a most intense interest in its great mysteries, and a thorough rever-xxvi INTRODUCTORY NOTICE. ence for its truths, when these were not disfigured by superstition or formalism. His large thoughtfulness made him indifferent to minor matters, which to many minds represent so much of religion, and he had perhaps too vehement a dislike to certain aspects of pietistic activity; but he had true religious im- pulses; and Christian truth, expressed in a manly, straightforward, and unexaggerated manner, always impressed him. He was open to the light from whatever quarter it might come; but he also felt that there was much regarding which we must be content here to remain in darkness, and to await the solution of the future. "There was at all times in Professor Ferrier's character great sweetness and a certain charm of loyal and chivalrous feeling, combined with passion- ate energy and decisiveness, amounting to obstinacy where his supposed rights or interests were in- volved. In the last years of his life these stronger features dropped out of sight, and all the gentle chivalry and forbearance of his nature came forth more prominently. He had for some time laid aside all ambition. He had forgiven his philosophical enemies, and even forgotten, as if it had never been, the painful crisis signalised by his pamphlet on the 4 Old and the New Philosophy/ He was surrounded by those he loved, and by many attached friends who vied with each other in their respect and affec- tion for him. He felt at the same time that his strength was rapidly failing, and that the end ofINTRODUCTORY NOTICE. xxvii his work was not far off. All this exerted a soften- ing influence on his character, and brought out its finer traits. He had long known, there is reason to think, of his weakness, and that there was something mortal in it. He certainly had no faith that any change of scene or any appliance of medical skill would be of avail in his case; and so he quietly, steadily, and cheerfully faced the issue. There was a singular depth and immovableness in his cheer- ful patience. I do not think I ever heard him complain, and I have seen him in great languor and pain. He might give utterance to a half-play- ful, half-grim expression regarding his sufferings, but he never seemed to think there was anything strange in them, anything that he should not bear calmly as a man and as a Christian. Neither did he say much of unfinished work which he might have done, although such work had been formerly much in his heart. He expressed few regrets, he spoke of no fears. He looked heroically yet humbly into the future, and did such work as he could with interest and diligence to the end. On the very day before his final seizure, I believe, he was in his library, as was his wont, busy amongst his books. "Many men can do good and able work in the world, but there are only a few anywhere, in any institution, who invest their work with that nameless personal influence which captivates while it instructs the young, which quickens their intellectual enthu- siasm and expands and refines their feelings in thexxviii INTRODUCTOKY NOTICE. process of education. No one was ever more gifted with this rare endowment than Professor Ferrier. There was a buoyant and graceful charm in all he did, a perfect sympathy, cordiality, and frankness, which won the hearts of his students, as of all who sought his intellectual companionship. Maintaining the dignity of his position with easy indifference, he could condescend to the most free and affectionate intercourse; make his students, as it were, parties with him in his discussions, and while guiding them with a master-hand, awaken at the same time their own activities of thought as fellow-workers with him- self. There was nothing, I am sure, more valuable in his teaching than this, nothing for which his stu- dents will longer remember it with gratitude. No man could be more free from the small vanity of making disciples. He loved speculation too dearly for itself, he prized too highly the sacred rights of reason, to wish any man or any student merely to adopt his system or repeat his thought. Not to manufacture thought for others, but to excite thought in others, to stimulate the powers of inquiry, and brace all the higher functions of the intellect, was his great aim. He might be comparatively careless, therefore, of small processes of drilling and minute labours of correction. These, indeed, he greatly val- ued in their own place. But he felt that his strength lay in a different direction, in the intellectual im- pulse which his own thinking, in its life, its richness, and clear open candour, was capable of imparting.INTRODUCTORY NOTICE. xxix He conducted his thinking, as it were, in broad day. The student could see every turn and winding of it; and the frankness of his manner gave a singular attraction to the frank boldness of his intellect, and more than anything, perhaps, explained the mingled love and admiration with which he was regarded. And yet, with all his easy cordiality, so manly was he, and so commanding the natural relations of his mind to others, that I do not fancy it could have entered into the head of even the most presumptu- ous student to take any liberty with him. If it was his happy power to stimulate enthusiasm and call forth interest in the young, he was no less able, in all circumstances, to preserve the most perfect order. And while he awakened affection, he never failed to secure respect." Professor Shairp of St Andrews writes as fol- lows :— " In the autumn of 1857 circumstances con- nected with my appointment at St Andrews led to a long correspondence, which I have not preserved. But the one impression left on me was that of Ferrier's manliness, justness, and high honour, combined with the finest consideration and most delicate courtesy towards all concerned. Not to speak of personal gratitude towards him for having so smoothed the way through many practical difficulties, the whole tone of his letters left on me a delightful impression of his character. I need hardly say that my inter-XXX INTRODUCTORY NOTICE. course with him during the next seven years was entirely according to this beginning. "Now and then, when I could, I used to go and hear him lecture; I never saw anything better than his manner towards his students. There was in it ease, yet dignity so respectful both to them and to himself that no one could think of presuming with him. Yet it was unusually kindly, and full of a playful humour which greatly attached them to him. No one could be farther removed from either the Don or the Disciplinarian. But his look of keen intellect and high breeding, combined with gentleness and feeling for his students, com- manded attention more than any discipline could have done. " In matters of college discipline, while he was fair and just, he always leant to the lenient and forbearing side. He was peculiarly considerate of the students in all his dealings with them; and by showing this markedly in his manner, I doubt not he called forth in those who perceived it some feel- ing akin to his own. " Till his illness took a more serious form, he was to be met at dinner-parties, to which his society always gave a great charm. In general society his conversation was full of humour and playful jokes. A quick yet kindly eye to note the extravagances and absurdities of men. His remarks were especi- ally racy on those whose enthusiasm outran their judgment, or who insisted on riding their ownINTRODUCTOEY NOTICE. xxxi hobbies, or forcing their own idiosyncrasies on others who had no mind for them. "Sometimes, when we found him in his library on a winter afternoon, he would begin talking of Horace, who was a special favourite of his. He used to amuse himself with translating some of the Odes into English verse, and he would now and then read what he had done in this way. These translations were always unconventional and racy, sometimes very felicitous in their turns. They brought out a vein of secret humour running through many of the Odes in which it had not been hitherto suspected. "At other times I have heard him discourse of Wordsworth, and of the early feelings which that great poet had awakened in him. When he spoke on this and other kindred subjects he brought out a richness of literary knowledge, and a delicacy and keenness of appreciation, of which his philosophic writings, except by their fine style, give no hint. I used sometimes to think that the exclusively abstract line of thinking to which he had in his later years devoted himself, and the demonstrative form into which he had tried to cast his thoughts, had shut out the free play of those imaginative perceptions, with which, unlike most other living metaphysicians, he was by nature richly gifted. "His malady, which no doubt he himself had known long before, first revealed itself fully to those beyond his own household by the severe illness withxxxii INTRODUCTORY NOTICE. which he was attacked a few days after the instal- lation of Mr Stirling of Keir as Lord Eector. At the dinner given on that occasion Mr Ferrier had, it was thought, caught a cold, which brought on a dangerous increase of heart-complaint. Though he rallied from this for a time, he never was as he had been before. Some more dangerous symptoms showed themselves in the summer of 1863; and I remember, on going to see him when we returned here in the autumn, that he spoke of his own health, not in a desponding tone, yet in a way that showed he had no hope of recovery. " How he bore the long painful winter that followed you have heard from others, and yourself, I think, had opportunities of seeing. In the visits which I made to his bedroom from time to time, when I found him sometimes on chair or sofa, sometimes in bed, I never heard one peevish or complaining word escape him, nothing but what was calm and cheerful, though to himself as to others it was evi- dent that the outward man was fast perishing. The last time but one that I saw him was on a Sunday in April; it must have been either on the 17th or 24th. He was sitting up in bed. The conversation fell on serious subjects, on the craving the soul feels for some strength and support out from and above itself, on the certainty that all men feel that need, and on the testimony left by those who have tried it most, that they had found that need met by Him of whose earthly life the Gospel histories bear witness. This,INTRODUCTORY NOTICE. xxxiii or something like this, was the subject on which our conversation turned. He paused, and dwelt on the thought of the soul's hunger. 4 Hunger is the great weaver in moral things as in physical. The hunger that is in the new-born child sits weaving the whole bodily frame, bones and sinews, out of nothing. And so I suppose in moral and spiritual things it is hunger builds up the being.' This was the purport of what he said, though of the words I cannot be sure that I give them faithfully. This was the last time I ever conversed with him." Professor Campbell of St Andrews says :— " You have asked me for some personal recollec- tions of my lamented and revered colleague, Professor Eerrier. Though I had seen him at St Andrews in 1854, and once again at Oxford, I date my acquaint- ance with him from the autumn of 1863, when I was a candidate for the Greek Chair at St Andrews, at a time when he had been already for some months a sufferer. On becoming settled at St Andrews we were most kindly received, notwithstanding his ill- ness, by him and his family; and I have a grateful recollection of his lively interest, more welcome be- cause unobtrusive, in my novitiate as a professor. He also asked me about the work which I had left, in which I said I had gained friendships which made life richer. He said—' You may find that here too.' " During the early part of my first session, which was his last, while he was still able to meet his class cxxxiv INTRODUCTOKY NOTICE. in his own house, we had several conversations on philosophy, a privilege which after his illness in December could not be permitted me, though I had frequently the pleasure of seeing and of talking with him. " At this time he was deeply interested in the study of the early Greek philosophers, and I remember his saying: ' I think what they were all driving at was to find something that ivill outlive us! This was said with much earnestness, and I have now before me the still deeper expression of solemnity and ven- eration which passed over his countenance when, after speaking of the duality implied in all cogni- tion, he added,4 And then in God also—to speculate about Him—in God also there must be duality, in so far as He knows Himself.' The tone in which these words were uttered made me feel that true reverence is without fear. I could understand, after hearing it, with what humble and fearless confidence he had said, when some religious question was dis- cussed in his own family, ' I suppose I shall know about this by-and-by.' "I will only add that, besides his fortitude and cheerfulness, which seemed perfect, there was a cour- tesy which never flagged or drooped, and a kindly interest, maintained until the last, in the most trifling occupations not only of his own family, but of their friends. " Perhaps I might have said something of his won- derful popularity with the students, but of that youINTRODUCTORY NOTICE. XXXV will have heard from others. His perfect courtesy, manhood, and native dignity were, with his stimu- lating intellect, the secret of their love for him. " I am sorry that I cannot recall more of our brief intercourse, which I shall always be most thankful to have enjoyed." Professor Yeitch, formerly of St Andrews, now of Glasgow, may be quoted in conclusion. " I first knew Mr Ferrier personally in the winter of 1860-61, as his colleague in the University of St Andrews. At that time his health, though good, was not robust. He seldom walked for recreation, spend- ing his time almost exclusively, when not in his class-room, in his library among his books. Drawn to him partly by the interest of common studies, but quite as much by the attractive nature of the man, I very soon came to cherish for him the warmest affection. Eefined, courteous, and genial, no speck of the pedantry which occasionally marks the man of recluse habits was visible in his manner. His devotion to abstract thought had in no degree dried up the freshness or limited the fulness of a mind that was from the first keenly susceptible of impres- sions from all that is highest and finest in nature and art. His early studies and training had been literary rather than philosophical; the beauty of form and style in which his thoughts were cast bore marks of this early culture. "His one absorbing intellectual interest was ab-xxxvi INTRODUCTORY NOTICE. stract speculation, and that, above all, in the direc- tion of metaphysics. He had a remarkable power, in conversation on metaphysical points, of testing and turning on all sides dogmas received or advanced. I shall ever look back with mingled feelings of plea- sure and regret on the long evenings of two-handed discussion which we spent together during the four winters of my residence in St Andrews. For depth of natural interest in the highest speculative ques- tions ; for openness, candour, and withal subtlety of fence, I have met no one who has surpassed him. He had, as seemed to me, no great interest in the questions of psychology, or in the details of formal logic; and he had read but slightly in either depart- ment. But metaphysic was his delight and his strength. The problem of Being, what it is; how to be analysed; how made intelligible; to get its principle and deduce its forms — was the centre round which his whole thought turned. The solu- tion of the problem which he worked out for himself penetrated his entire life and convictions. His met- aphysics were less of a professional accomplishment, and more completely himself, than was probably the case with any man, excepting Hamilton, whom 1 have known. His interest in ethical speculations seemed to me to be entirely subordinate to his meta- physical ; and any ethical doctrine which he reached took its cast from his demonstrative theory of know- ledge and existence. " The play of his intellect was fine, subtle, arrowyINTRODUCTORY NOTICE. xxxvii in its keenness and directness. His metaphysical system, whatever may be thought of its compass or truth, was clear as daylight through all its depths. It professed, indeed, to afford a level line of demon- stration, on which, when once one sets out, there is no pause until the whole apparent mystery of reality is reached and cleared. His abstractions and refine- ments were lofty and subtle, but his imagination had always a concrete embodiment for the airiest and least palpable of them. The literary and artistic faculty, to which he had given free scope in his earlier days, was now the handmaiden of his intellect, and set the most abstract of his conceptions in luminous illustra- tions and exquisite shapes of poetry. He retained the mastery of a style, clear, idiomatic, and brilliant, which, even when he discoursed on metaphysics, ' Caught at every turn The colours of the sun.' More intellectually intense than excursive, more taken with the harmony and the march of demon- stration than with the requirements and the facts of real life or the teachings of experience, he sought to determine by deduction from principles of rea- son the essential nature of things, and of existence in its greatest generality. ' Eeasoned truth' was with him the highest, the only philosophy; in his entire intellect and interests he was the type of the phil- osopher of the abstract and deductive school. "When I first became acquainted with Mr Ferrierxxxviii INTRODUCTORY NOTICE. his speculative ardour seemed to be leading him to- wards a principle of even higher abstraction than that of the 'Institutes.' The author at this time most congenial to his mode of thought was Hegel. He studied Hegel for certainly more than the last ten years of his life, without, as he himself used freely to acknowledge to the end, completely satisfy- ing himself that he had mastered the Hegelian con- ception,—a fact worthy of note by the fluent praters about Hegel in these times. It was obvious, how- ever, from his conversation, that during these latter years his thoughts were a good deal directed to the realisation of glimpses of this conception, and to its application in various ways. I doubt whether he had in this line reached a point that was entirely satisfactory to his own mind. His speculative efforts were, I suspect, purely tentative. " As a Professor, he was equalled in power and in- fluence by few who have occupied university chairs. He made men thinkers,—not, however, by any routine of drill or discipline, but by his hold of his subject, the wonderful clearness and force of his prelections, and the outflowing of his personality into all that he said and did. The respect, affection, and obedience of his class were given to him spontaneously as a tribute of loyalty to the man. " Ferrier's was altogether a strong nature, one in which were blended high and rare qualities, yet harmoniously vigorous. To force of intellect there were added depth of feeling and strength of will;INTRODUCTORY NOTICE. xxxix resolution which, once taken, was indomitable. But never were stern qualities set amid more genial sur- roundings, or united with greater kindliness, courtesy, warmth, and steadiness of affection. Socially, he was one of the most pleasant, interesting, and attractive of men. No description will ever enable one who was a stranger to him personally to realise the depth of humour and the raciness of wit which were in him. This was quite a part of the man, spontaneous and irrepressible in its outflowings, breaking forth often when least expected, so as to relieve the dulness, it might be, of college deliberations, or infuse pleasantry into the occasional fierceness of university polemics. " He is now with us no longer; the soul that strug- gled so hard with the hardest things for human thought has passed away after an afflicting illness, that was borne most touchingly, most heroically. We miss the finely-cut, decisive face, the erect manly presence, the measured meditative step, the friendly greeting; but there are men, and Ferrier was one of them, for whom, once known, there is no real past. The characteristic features and qualities of such men become part of our conscious life ; memory keeps them before us living and influential, in a higher, truer present which overshadows the actual and visible." To his friend and son-in-law, Sir Alexander Grant, was intrusted the disposal and revisal of Mr Ferrier's manuscript compositions. Fitted alike by his interest in the subject, and his affectionate intimacy with thexl INTRODUCTORY NOTICE. deceased, for the fulfilment of this pious duty, he readily accepted the task; but his early return, after a few months' furlough, to the labour of an important office in India, compelled him to relinquish the actual publication. Another friend, who had the advantage of consulting unreservedly with Sir Alexander Grant, and being made fully acquainted with his views, un- dertook, in accordance with Mrs Ferrier's wishes, to prepare these volumes for the press. For the appear- ance of these lectures in their present form, and for the selection of such among his other writings as are here put together, the second editor alone is respon- sible. The lectures on Greek Philosophy were mainly com- posed, or at least delivered in the shape into which Mr Ferrier finally brought them, about the year 1859. Be- fore this year he had lectured on some periods of Greek Philosophy, and may in several cases have incorpo- rated his earlier with his later lectures. Some parts of the remarks upon Aristotle bear the date 1857 and 1858; others again seem to have been written as late as February and March 1863. Of the discussion re- ferring to the Stoics and Epicureans, some papers have marginal dates of 1857 and 1858, as well as later notices of 1860, 1861, and 1862. The earlier part, as far as the end of the Cyrenaic, Cynic, and Megaric schools, appears to have been more fully elaborated than what follows. His lectures up to this point were carefully written out in two bound manuscript volumes, of which the first bears the title, ' LecturesINTRODUCTORY NOTICE. xli on the History of Greek Philosophy.—I. The Pre-Soc- ratic Period. 1859-60 ;' and the second, ' Lectures on the History of Greek Philosophy.—II. The Soc- ratic Period. 1860-61-62.' The remaining portion was mostly written on loose sheets; these were fre- quently revised and corrected: in some cases where later lectures have been incorporated with earlier ones, it is not easy to determine precisely how much of the earlier he intended to retain, or how much he con- sidered superseded by the later. Here and there paragraphs are marked " Omit;" these the editor has judged right to exclude from the work, though not clearly certain whether the omission thus directed merely referred to the particular occasion of the lec- ture being delivered, or was meant to imply a purpose of rewriting or expunging the paragraphs. Some omissions have also been made of passages where the subject handled was not directly Greek Philosophy, but one which, though closely connected with it, has received full treatment in various other works; for instance, the lives of the more eminent philosophers. To include the biography of Socrates, Plato, and Aris- totle, perfectly suitable as it was in lectures addressed to youthful learners, appeared unnecessary in a review of Greek Philosophy. This rule of exclusion, how- ever, did not always seem applicable to the less illus- trious occupants of a place in the history of metaphy- sical speculation. It appears from the MS. that the lecturer occasionally read to his class articles con- tributed by himself to the ' Imperial Dictionary ofxlii INTRODUCTORY NOTICE. Universal Biography.' Use has been made of this work, especially in the latter portion of the lectures. The lives of Schelling and Hegel are taken from the same publication, with the kind permission of the publisher, Mr Mackenzie, of Howard Street, Glas- gow.* The second volume contains the papers on phil- osophical subjects which Mr Ferrier published in ' Blackwood's Magazine,' and a few occasional lectures which appeared to deserve insertion, with one or two specimens illustrating his general literary faculty. It is probable that if he had republished these essays he would have remodelled and rewritten much; pos- sibly omitted many portions; and it would be in nowise surprising if treatises composed at so early a stage in his speculative progress exhibit either a seeming or an actual discrepancy from his later and more matured opinions. It might indeed be matter for juster surprise if such difficulties did not fre- quently occur in the writings of any original thinker, when separated by a long interval in the date of their production. It should not be forgotten that what, seen from without, may present the look of a partial inconsistency, may often more justly from within be regarded as a reconciliation and union of two different aspects of truth. " There is nothing * Several other articles in this work are from the pen of Mr Ferrier, and may be distinguished by having his initials affixed. Among those likely to interest the general reader may be noticed Adam Smith, Swift, and Schiller.INTKODUCTOKY NOTICE. xliii to retract, but much to carry forward, and which has been carried forward, as I trust one day to show," was an expression used by him in speaking of these papers. Whether the conflict between his earlier and later views be real or apparent, the editors have not felt themselves authorised to attempt any correc- tion or amplification; these essays are left as they were originally written, with omission of one or two pages quite irrelevant to the purport of the argu- ment. They believe this plan to be in accordance with the spirit which animated Mr Ferrier's own re- searches : for he was far too fearless and faithful a follower of truth to have hesitated for a moment to throw aside an opinion once held, if shown to be fal- lacious, or to doubt that from the collision of im- perfectly discerned truths a spark might be struck out that would light to further insight. Those to whom the system of this philosopher, when brought nearer to maturity, presents matter of interest, will thus have the best assistance that can be supplied towards tracing its growth through successive stages; they are asked in return nothing but what every labour of thought has a right to claim from a reader, to understand each combination of ideas, where there can be room for doubt, according to their best admis- sible meaning. Many may be of opinion that some regions into which the ocean of philosophic discovery spreads, have not been tracked with sufficient diligence by this explorer; such comparative incompleteness mayxliv INTRODUCTORY NOTICE. render his system less valuable in the eyes of some than it will seem to others: there may be readers to whom its fundamental axioms are a stumbling- block. A few may dare to believe that in originality, depth, and truth, it is surpassed by no philosophy which this century has seen produced in Britain. The sincere thanks of the editors are due to some of Mr Ferrier's early friends, who have kindly con- tributed the best help they could towards rendering this brief introduction less incomplete than it might have been; Professor Solly, of Berlin, and George Makgill, Esq. of Kemback, are entitled to especial acknowledgement. E. L. L. POSTSCBIPT FOR THIBD EDITION. As a slight indication or specimen of the recep- tion which Ferrier's philosophy, when first pub- lished, met with in Germany, two translated ex- tracts are subjoined. It would be easy, but it is unnecessary, to multiply such testimonies. The editors from time to time receive evidence that the impression made by Ferrier's philosophy has not been ephemeral, but that in Scotland, in Eng- land, and even in France, young minds are still captivated by Ferrier's manner and stimulated by his thought; and that mature and profound thinkersINTRODUCTORY NOTICE. xlv recognise in him a metaphysical genius whose achievements the world will not willingly let die. A. G. E. L. L. 1. From a notice of Ferrier's ' Institutes of Meta- physic,' by Dr Wirth, one of the Editors of the ' Zeit- schrift fur Philosophie und philosophische Kritik,' vol. xxx. p. 243 (1857):— "We hail in this volume one of the cheering signs that English philosophy has raised itself above the one-sided empiricism which has long been predom- inant in it, to a higher standpoint of knowledge, uniting empiricism and idealism; at the same time a sign of the approach towards German idealistic speculation, noticeable too in other instances, among the deeper thinkers on the other side of the Chan- nel. While our German philosophy has descended step by step from the ethereal height on which in earlier days Fichte's Idealism moved, till in some writers it has taken a completely sensualistic form, and so laid the foundation for the most determined materialism—a process analogous to the evolution of Greek philosophy in its second period, beginning with the idealism of Plato, and ending in sensual- ism, materialism, and lastly, a scepticism despair- ing of all knowledge — writings like this of Ferrier's seem to prove that, conversely, Englishxlvi INTRODUCTORY NOTICE. philosophy, after taking an empirical starting- point in Bacon, and being carried on farther in the same direction by Locke, is recently mak- ing an effort to take into itself the a priori and idealistic element of knowledge. Assuredly this tendency to unite the idealistic element with realism is so interesting and important a phenomenon, that we have every reason to take special notice of it in reviewing this work. The author endeavours throughout to raise himself above the antitheses in which abstract thought so easily becomes entangled, especially that of realism and idealism, and to grasp firmly their unity. . . . He is entirely in the right when he repels the charge that the law of cognition laid down by him is a one-sided or sub- jective-idealistic principle. He maintains that it never occurred to genuine idealism to deny that things really exist externally to ourselves. Idealism, he avers, not denying this, asks only what is meant by external, apart from all relation to an internal; and he proves that without this relation the word exter- nal has and can have no meaning." After a more detailed examination of the work, the reviewer states his aim to have been " to show that what I regard as the genuine fundamental idea of recent German philosophy is now opening a path for itself among our kinsmen the English; and I hope that the dif- ferences which I have expressed from the honoured author, if this notice meets his eye, will be regarded in the true light in which they seek to be regarded,INTRODUCTORY NOTICE. xlvii as put forward not with the purpose of impugning that fundamental idea, but rather with the aim of throwing clearer light upon it from a nearly-related point of view." 2. From a notice of' Lectures on Greek Philosophy/ &c., 2 vols., by Professor Hermann Ulrici, an Editor of ' Zeitschrift fur Philosophie und philosophische Kritik,' vol. liv. p. 185 (1869):— "The 'Philosophical Remains' include not the whole but the best and most important portion of the writ- ings on philosophy left by James Frederick Ferrier, Professor of Moral Philosophy and Political Economy at the University of St Andrews, who died 11th June 1864. We know the author through his ' Institutes of Metaphysic,' a work which even in England made a strong impression, and shortly after its appearance received a notice in this periodical which entered into and duly appreciated its views. We lament with the editors the premature death of this eminent man, whom we rank far higher than the newest cele- brities for the day of English philosophy (J. S. Mill, A. Bain, &c.)—the more since he had the courage to do battle against the stream of shallow empiricism which English philosophy still follows, and which in consistency leads inevitably to one-sided materialism, sapping not only all ethical science, but all science whatever. " The first volume contains almost exclusively lec- tures on the history of Greek philosophy, which Fer-xlviii INTRODUCTORY NOTICE. rier repeatedly delivered before the students of his University. He praises in the introduction Hegel and Zeller as the historians of philosophy who made the first successful attempt' to grasp the inner soul rather than the external environment of bygone speculations, and to trace the logical concatenation of systems.' . . . The lectures are distinguished by abundant originality of conception, by clearness and thoroughness of exposition, and by the skill with which, entering into his hearers' standpoint and power of apprehension, they succeed in smoothing their road to the understanding of philosophy and its history. Pre-eminently directed to this end is a copious introduction on the essence and conception of philosophy. In this respect they may well be recommended to many of our historians, and to all who have to deliver lectures on the history of philo- sophy, as models worthy of careful study."GREEK PHILOSOPHY. I. THE PRE-SOGJtATIC PERIOD. INTRODUCTORY. 1. In the present session I propose to treat of the history of Philosophy, both moral and metaphysical, on a more extended scale than I have yet been in the habit of doing. Philosophy itself must, of course, engage our attention; because, unless we know what philosophy is, unless we have a clear conception of its aim and results, the history of philosophy must remain a blank, a sealed book, a mere repertory of dead and unprofitable dogmas. But when we have once formed a right conception of philosophy, the study of its history will then be found to react power- fully in confirming and enlarging our knowledge, and in directing and enlightening our energies. The aim of philosophy is to raise us into the region of uni- versal, or, as I may call it, unindividual, thinking; the accidents of reason must fall away, and the a9 GREEK PHILOSOPHY. essence of reason must stand forth declared: all that is arbitrary in human thought must disappear; and we must rest on the necessary elements of mind and of the universe. That is the end which philosophy proposes to her votaries, because it is only through this abnegation of particular or optional thinking that universal truth can be attained. This is the end which, on a small scale, must occupy the indi- vidual thinker; it is the end which, on a large scale, has occupied all the generations of philosophers from the dawn of speculation until now. Hence, in study- ing the history of philosophy, we shall find that we are in fact studying only the development of our own reason in its most essential forms, with this difference, that the great problem which, in our minds, is worked out in a hurried manner, and within contracted limits, is evolved at leisure in the history of philosophy, and presented in juster and more enlarged proportions. The history of philosophy is in fact philosophy itself taking its time, and seen through a magnifying-glass. 2. The chief aim of the historian of philosophy ought to be, to give a continuity or organised con- nection to the different parts of his narrative. But to do this, he must endeavour to verify in his own consciousness, and as the indigenous growth of his own mind, the speculations of antecedent thinkers. He may not agree with these speculations; but he ought, above all things, to understand what they mean—what they are in their spirit, and not merelyINTRODUCTORY. 3 in the letter. When I say that he must verify these doctrines in his own consciousness, I mean that he must actively reproduce and realise them in his own thoughts, together with the grounds on which they rest. He must be able to place himself in the mental circumstances in which they arose, and must observe them springing up in his own mind, just as they sprang-up in the minds of those who originally pro- pounded them. They must be to him, not the dead dogmas of their thinking, but the living products of his own. They must come to him not as antiquated traditions, but as teeming with present interest, and as fraught with a present and inextinguishable vital- ity. As an original thinker, he must reanimate these doctrines from within, while as a critic and historian, he is engaged in receiving and deciphering them from without. What he receives from others he must also find as the indigenous growth of his own mind. What he must be able to say to himself is this: Such a system, or such a doctrine, or such a problem, is not what some individual thinker has chosen to think, or has accidentally thought, but it is what thinking itself, in certain circumstances, must inevitably think. It is only when he conceives and executes his vocation in this spirit that the historian of philosophy can be regarded as having verified and reanimated the systems which he is expounding. When he has so verified them—verified them in the manner thus imperfectly described—he has obeyed the primary obligation by which the historian of4 GKEEK PHILOSOPHY. philosophy is bound, and has fulfilled a requisition which either contains all other rules, or renders all other rules superfluous. 3. In the older histories of philosophy this rule is but little attended to, this obligation is very imper- fectly fulfilled. They abound in learning, but they are lamentably deficient in insight. They are in general mere repertories of disjointed and exploded opinions, of capricious and arbitrary thoughts, which, as presented in these compilations, contain no point of interest for any living soul. The letter is there, but the spirit has altogether fled; there is abundance of the husk, but the kernel is nowhere to be found. 4. Of late years the history of philosophy has been studied in a profounder and more rational spirit. Living insight has been aimed at rather than dead learning. Attempts have been made to grasp the inner soul rather than the external environment of bygone speculations, and to trace the logical filiation of systems. These attempts, it must be owned, have been only partially successful. Much still remains to be done. The ground has been broken; but it cannot be said that the jungle has been cleared, or the roads made. The most diligent pioneers in this good work have been the two German philosophers, Hegel and Zeller. But Hegel's work on the history of philosophy labours under the disadvantages inci- dent to a posthumous publication, and seems in manyINTRODUCTORY. 5 places to contain mere hints which probably were more fully expanded in the oral delivery of his lec- tures. Much of it may be described as made up of dark, abrupt, and laconic jottings. Zeller's history of the Greek philosophy is in some respects more complete, and is indeed a very valuable work: but it is too much pervaded, particularly in those places where clearness is most required, by that obscurity, indeed I may say unintelligibility, which seems to be inseparable from the philosophical lucubrations of our Teutonic neighbours. With all these shortcomings, however, I am of opinion that these two historians of philosophy, Hegel and Zeller, are entitled to take precedence before all other inquirers in this difficult field of research. 5. To enable the historian of philosophy to enter on his work with any chance of success, we have now to consider what equipment he requires—requires on his own account, and also on account of those whom he addresses. "We have to consider what preliminary study he has to go through before he can prosecute his researches successfully, and what preparatory in- formation he must lay before his audience before he can expect to render intelligible to them the result of those researches. It is principally, I think, in regard to this preparatory or introductory matter that all the histories of philosophy are wanting; and it is for the purpose of supplying this defect, and of remedy- ing it in so far as I can, that I proceed to speak of6 GREEK PHILOSOPHY. what I conceive to be the essential preliminaries to the study of the history of philosophy. 6. The essential preliminary to the study of the history of philosophy is, a clear conception of philo- sophy itself. Without this the history of philosophi- cal systems cannot be studied to much—or, I would rather say, to any—advantage. It may be thought that philosophy itself is best learned from the study of its history: and there can be no doubt that the latter reacts upon the former in the way of rendering our conception of philosophy more definite, as well as more comprehensive. The conception of philo- sophy is confirmed and enlightened by the survey of philosophical systems. But without some tolerably definite conception of what philosophy is, and of what it aims at, the study of these systems is a vain and unprofitable pursuit. We must have this con- ception to begin with—we must have it to found upon—otherwise we cannot expect to derive any in- tellectual improvement from the study of the history of philosophy; we shall be baffled and bewildered at every turn by the apparent extravagances and unin- telligibilities which we encounter. Even when we carry with us a clear conception of philosophy, we are frequently perplexed when tracing historically the mazy windings of speculation; but without this clue we should be utterly lost and confounded. 7. What, then, is the conception of philosophy?INTRODUCTORY. 7 I cannot tell you this in one word or in one sentence. We must make our approaches to it gradually, be- ginning with what is very indefinite, and making it more definite as we proceed. Let us begin, then, with a definition, which, though it conveys very little in- formation, is quite unexceptionable—is, indeed, what the whole world is willing to assent to—and let us say that philosophy is the pursuit of truth. This is the first, and simplest, and vaguest conception and definition of philosophy which we can form. 8. This definition calls for some explanation as to what we mean by truth. When we say that philo- sophy is the pursuit of truth, we must at any rate have some notion of the object of which philosophy is the pursuit. What, then, do we mean by truth ? I commence by calling your attention to a distinc- tion by means of which we may clear up our idea of truth, and bring ourselves to understand what it means; I refer to the distinction of truth into truth relative and truth absolute. When I have explained what these two kinds of truth are, we shall then be able to render our definition of philosophy more dis- tinct and complete by declaring whether philosophy be the pursuit of truth relative or of truth absolute. I proceed, then, to speak first of relative truth, and secondly of absolute truth. 9. First, of truth as relative. A relative truth is a truth which is true for one mind, or for one order8 GKEEK PHILOSOPHY. or kind of minds, but which is not or may not be true for another mind, or for another kind of minds. All sensible truth is or may be of this character; indeed, all truth which the physical organism is in- strumental in bringing before the mind is merely relative. It is merely relative, because with a dif- ferent organism a different truth would be presented to the mind. This may be readily understood with- out much illustration. If our eyes were constructed like microscopes, the world would present to us an aspect very different from that which it now wears; if they were formed like telescopes, the spectacle of the starry heavens would be wonderfully changed. If the sensibility of our retina were either increased or diminished, the whole order of colours would un- dergo a corresponding variation. So, too, in regard to sounds and tastes: alter the organism on which these depend, and what was once true in regard to them would be true no longer; the thunder might sound softer than the zephyr's sigh, or the lover's lute might be more appalling than the cannon's roar. So, too, even in regard to touch: if our touch were strong and swift as the lightning's stroke, the most solid matter would be less palpable than the air. So purely relative is the truth of all our sensible impres- sions : and many other truths with which we have to do may be admitted to be of the same relative char- acter—to be truths merely in relation to us, and to beings constituted like us, but not necessarily truths to other orders of intelligence.INTRODUCTORY. 9 10. Secondly, of truth as absolute. As relative truth is truth which is true for one mind, or for one order of intelligence, so absolute truth is truth which is true for all minds, for all orders of intelligence. It is plain that absolute truth cannot mean truth placed altogether out of relation to intelligence, for that would be equivalent to saying that the highest truth could not be apprehended by the most perfect intelligence, not even by omniscience. To define absolute truth as that which stands out of relation to all reason—as that which is not to be known on any terms by any intelligence—is a position too absurd to require any exposure. All truth, therefore, is in this sense relative, that is, can be conceived only in relation to intelligence; but the distinction between absolute truth and relative truth is, as has been stated, this: that relative truth is what exists only for some, but not necessarily for all minds; while absolute truth is that which exists necessarily for all minds. We shall find hereafter that this distinction is of great service to us in leading us to understand the grounds upon which philosophers generally have set so little store on the truth of our mere sensible impressions. No philosopher ever denied that the intimations of the senses are relatively true, or that we should place implicit confidence in them as pre- sentations relatively true. But many have denied that these intimations were absolutely true, were valid of necessity for all minds. The grounds, how- ever, on which those philosophers proceeded, have10 GREEK PHILOSOPHY. been frequently mistaken. Hence many perplexities have arisen, and hence speculative thought has been often unjustly charged with inculcating absurdities, which existed nowhere except in the misapprehen- sions of its accusers. 11. Having thus explained and defined (intelligibly, I trust, though not fully, and perhaps not convinc- ingly) the distinction between relative truth and absolute truth, we have now to ask, Which of these two forms of truth is the special object of philo- sophy ? The answer is, that the attainment of ab- solute truth, of truth as it exists for all intellect, is the principal, though not the exclusive, aim of philosophy. Philosophy must not overlook alto- gether the consideration of relative truth, because perhaps a finer analysis will show us that the two are ever blended together in an essential and in- separable contrast. But nevertheless, as I have said, absolute truth is the principal, indeed the proper, object at which philosophy aims; it is the point at which all the higher metaphysicians of every age and of every nation have aimed, and at which it is their duty to aim (however far short of the mark their efforts may be doomed to fall), if they would con- tinue true to their vocation. 12. A question here arises which threatens to cut short our progress: Are man's faculties competent in any degree to the attainment of absolute truth ?INTRODUCTORY. 11 The whole prospects of philosophy, according to the conception of it which we are endeavouring to fix, are obviously involved in the answer to this question. If we reply peremptorily that man's facul- ties are in no degree competent to the attainment of absolute truth, our discussion is at once cut short, and our conception of philosophy is annihilated. Such is the result if we answer this question in the negative. Therefore, while I admit the difficulty and the importance of the question, I am con- strained to answer it in the affirmative, although I cannot at present set forth fully the grounds of my decision. I answer it in the affirmative with this proviso — a proviso which may perhaps save me from the charge of speaking too dogmatically—and I say that man's faculties are competent to the attainment of absolute truth, provided and in so far as man's mind has something in common with all other minds; in other words, provided there be a universal intelligent nature in which he is a par- taker. It is obvious that this community of intellec- tual nature is the ground, and the only ground, on which man can lay claim to any knowledge of the absolute truth, because absolute truth has been de- fined as that which exists for all minds; but unless man's mind has something in common with all minds, absolute truth cannot exist for him, can have no meaning in reference to him; while, on the other hand, if he has something in common with all other intelligences, he may lay claim to an interest12 GREEK PHILOSOPHY. in absolute truth, and is competent to attain to it when the requisite exertions are put forth. 13. You thus perceive that the question regarding our competency to attain to absolute truth resolves itself into the new question, Is there in the mind of man a universal part—that is, a part which in all intelligences is essentially of the same character? Intelligence itself seems to constrain us to answer this question in the affirmative. That there is such a part seems to me to be an axiomatic truth of rea- son. To suppose, for example, that the supreme intelligence has nothing whatever in common with the human intelligence, is to suppose that the one of them is an intelligence, and that the other is no intelligence at all. It is to dissolve the very ground on which we conceive both of them as intelligences. Two intelligences which have nothing whatever in common cannot both of them be intelligences; they cannot be both placed under that category of thought, or indicated by the one word intelligence, because it is only through our thought that they possess some point or quality in common that we can think of them as intelligences; and therefore, to think of them as having no common quality, and at the same time to think of them as intelligent, is to think of them as both having, and as not having, something in common; in other words, it is to think a down- right contradiction. This truth, then, in regard to the constitution of the human minds, and of allINTRODUCTORY. 13 minds, namely, that they agree in some respect, seems to be a necessary axiom of reason. In all intelligence there is, by the terms of its conception, a universal, that is, an essential unity of kind, how- ever small the point of unity may be. 14. On religious grounds this unity might be much more largely insisted on. Its postulation is the very foundation and essence of religion. This unity con- stitutes the very bond, and the only bond, between the Creator and the creature. Deny this connection between the divine and the human reason, and you destroy the very possibility of religion. 15. I admit, however, that the answer which I have ventured to return to this question is one which cannot be expected to command your assent until you have time to reflect upon it more fully, and it is well worthy of your most attentive consideration. It is indeed the question of the present day, as it was the great question of philosophy in the time of So- crates and the Sophists. The whole sophistical phil- osophy proceeded on the assumption that there was, or might be, an absolute diversity of kind in the constitution of intellectual natures ; that different orders of minds had not necessarily anything what- soever in common. From whence it followed that there were as many kinds of truth as there were kinds of mind, quot mentes, tot veritates; in other words, that there was no truth at all, no absolute14 GREEK PHILOSOPHY. truth, no truth, in the strict sense of the word, any- where in the universe. In these few words are con- tained the sum and substance of the sophistical phil- osophy, and the arguments by which Socrates en- deavoured to rebut the conclusions of the Sophists proceeded on no other principle than that which I have attempted to place before you; the principle, namely, that there is a common nature, known by the name of reason, in all intelligent beings; and that, in virtue of this common nature, man can rise to some extent to the contemplation of absolute truth, which exists, and can exist, only as the coun- terpart and object of this common reason, of which man, in his degree, is a partaker. 16. But my object at present is not so much to settle the question in regard to the unity or common nature of intelligences, as to place before you a clear conception and precise definition of philosophy, a conception and definition which may be of service to us when we come to deal with the history of speculative systems. I defined philosophy at the outset as the pursuit of truth. I now define it as the pursuit of absolute truth; and farther, having defined absolute truth to be truth as it exists for all minds, I add that circumstance to the definition, and I affirm that " philosophy is the pursuit of absolute truth, that is, of truth as it exists for all intelligence."INTRODUCTORY. 15 17. What I wished principally to impress upon you in my last lecture was, the distinction between relative truth and absolute truth. All truth is, in one sense, relative ; that is to say, whatever we know or think of must be known or thought of in relation to ourselves. All that we know must be known in conformity with our capacities of knowledge, and cannot be known except under the conditions im- posed by these capacities. But here is where the distinction lies : relative truth is truth which comes to us in virtue of our particular nature as human intelligences ; absolute truth is truth which comes to us in virtue of our common nature, as intelligences simply, what is here looked to being merely the circumstance that we are intelligences at all, and not the circumstance that we are this or that particular kind or order of intelligence. Let us suppose a number of intelligences divided into different kinds, into various orders and degrees; you will observe that, by the ordinary logical doctrine, each of these kinds must embrace something peculiar to itself, and also something common to the whole number, how- ever numerous the classes of intelligences may be. Now, what I want to impress upon you is this : that each of these kinds of intelligence will know and apprehend partly in conformity with the peculiar endowment of what I have spoken, and partly also in conformity with the common endowment of which I have spoken. And what it apprehends in conformity with its peculiar capacity is relative truth; what it16 GREEK PHILOSOPHY. apprehends in conformity with its common capacity is absolute truth. It is further obvious from this explanation that relative truth is, as I have already frequently said, truth merely for some minds ; while absolute truth is truth for all intelligence: and this analysis of the mind into a common capacity and a peculiar capacity, furnishes us, we shall by-and-by see, the true ground of the well-known distinction of the human faculties into sense, understanding, and reason. 18. To return to our definition of philosophy: Without altering the meaning of that definition, I may slightly vary its expression; for ideas some- times gain in distinctness by being presented under different forms of expression. Truth, we may say, is that which is—it is the real; so that, instead of say- ing that philosophy is the pursuit of absolute truth, that is, of truth as it exists for all intelligence, we may say that " philosophy is the pursuit of the ab- solutely real, that is, of the real as it exists for all intelligence." These two expressions are synony- mous ; but, perhaps, to some of you the latter form of the definition may be the more significant of the two. 19. This definition may be open to objections ; but I cannot think that it is open to any well- founded objections. As objections, however, are actually urged, which are very pertinacious, if not very strong, some notice must be taken of them. They are so obtrusive, and they have carried withINTRODUCTORY. 17 them so much apparent weight, that the dominant philosophy of this country is founded upon a denial and repudiation of the definition which I have ven- tured to lay down as the only true definition of philosophy. In direct contravention of this, high authorities have maintained that philosophy is the pursuit of mere relative truth, of truth as it exists, not for all, but only for our intelligence. And they found this definition on the consideration that man can deal with truth only as it presents itself to his particular mental constitution. Their own doctrine and their objection to our position may be summed up under the following query, which they address to us: How is it possible for man to know or to speak of any truth, except such as exists for his 'particular intelligence ? How can he have anything to do with truth ? What can he know about truth as it exists for all intelligence ? 20. I answer, that man can have nothing to do with truth as it exists for all intelligence, can know nothing at all about it, unless there be something in his intelligence which links him to all intelligence; some point or quality in which his intelligence agrees with all other intelligences; in short, unless there be a universal or common nature in all intelligences. If there be this, if intelligence be to some extent universally the same, then it is obvious that man can know the truth as it exists for all intelligences; for he has merely to look to the truth which addresses B18 GREEK PHILOSOPHY. itself to the universal part of his own intelligent nature; this universal part being the same in all, the truth which it apprehends must be the same for all; in other words, that which it apprehends must be the truth for all intelligence, and not merely the truth for man's intelligence; it must be absolute and not mere relative truth. On the other hand, if it be true that there is no common nature, no universal faculty in all intelligence, no point in which all minds agree; in that case it must be admitted that the objection is fatal to our definition of philosophy. In that case man can have no dealings with absolute and universal truth; the only truth of which he can be cognisant must be relative and particular. But observe the contradiction in which we get involved if we take up this position. I have already stated what this contradiction is, and therefore I merely repeat my statement, that if we deny to intelligences a common nature in which they all participate, or if we deny to man's intelligence a participation in this common nature, we fall into the absurdity of at once including certain things under the same category of thought, and of excluding at the same time some of these things from that category. 21. My object at present is rather to furnish in- sight than to inspire conviction. I wish you rather to understand what I say, than to be convinced by what I say; and I think you may now understand distinctly the positions respectively occupied by theINTRODUCTORY. two parties who divide the philosophical world. On the one hand, we have those whom I venture to re- gard as the true philosophers. They hold, first, that there is some principle or quality or faculty common to all intelligence; and, second, that in virtue of this common faculty man is competent, to some extent, to apprehend the truth as it exists for all intelligence; in other words, is competent to apprehend the abso- lute truth. And founding on these two postulates, they obtain such a definition of philosophy as that which I have given you—a definition which follows at once from these two postulates, namely, that philo- sophy is the pursuit of the absolute truth, or of the absolutely real; that is, of the true and real as they exist for all intellect. On the other hand, we have those whom I venture to regard as the opponents of true philosophy. They hold, first, that there is no principle or quality or faculty common to all intelli- gence: and, secondly, that in consequence of there being no such universal principle, man is not com- petent to apprehend the truth as it exists for all intelligence; in other words, is not competent to apprehend the absolute truth: and founding on these two postulates, they obtain the following as their definition of philosophy—Philosophy is the pursuit of mere relative truth, or of the relatively real; that is, of the true and real as they exist merely for man's intelligence. 22. You have now before you the two definitions20 GREEK PHILOSOPHY. which express the two conceptions that lie at the root of the two great schools of philosophy that have divided the world, and two more fundamental con- ceptions of these antagonist philosophies I believe it is not possible to obtain. I have called both of these schools philosophical; but in strict speech we ought to say that while the one of them is philosophical, the other is anti-philosophical, for they are directly opposed to each other, as you may see from the opposite conceptions which each of them entertains in regard to the proper business of philosophy. But we need not quarrel about the use of a word; and, provided the opposition between the two parties be understood, we may apply the term philosophical to both of them. 23. But to render our definition of philosophy complete, something, indeed a good deal, still re- quires to be added to it. Philosophy, I have said, is the pursuit of the real as it exists for all intelligence. This definition proceeds, as I have said, on the pos- tulate—a postulate which I regard as axiomatic— that all intelligences know and think in some re- spects alike. It is not necessary, at present at least, to suppose that there are more intelligences than ours in the universe; but if there are other intelli- gences, it is necessary to suppose that they agree in some respect with ours, or, in other words, that all intelligences, actual or possible, have something in common. Now, the question here arises, What isINTRODUCTORY. 21 this universal principle, this faculty which is com- mon to all minds, in virtue of which we are able to apprehend the truth, not merely as it exists for us, but as it exists for all? What can we say in ex- planation of this faculty ? 24. To explain this universal faculty, I shall bring forward a few illustrations as the best means of ren- dering myself intelligible; or rather, without assum- ing that we have such a faculty, I shall produce the grounds which compel us to hold that there is some- thing universal, as well as something particular, in our intelligent constitution. When I apply sugar to my palate, and declare that the taste is sweet and agreeable, am I entitled to declare further that sugar is sweet and agreeable to all sentient and intelligent beings? Can I announce this as a truth for all intelligence ? Obviously I cannot; and why can I not ? Simply because I am under no compulsion so to regard it: I can help thinking it as a truth for all intelligence. And on what ground can I help so thinking it ? On the ground that an intelligence with a different organism from mine would apprehend the sugar differently. Therefore the truth for me, namely, that sugar is sweet and agreeable, cannot be laid down as a truth for all intelligence. Take another case. I say, "The earth goes round the sun." Is that a truth for all intelligence ? It looks very like one, but it is not one. And why not ? you will ask. I answer, for this reason: that a truth for all22 GREEK PHILOSOPHY. intelligence means a truth which is valid for all in- telligences which may have existed in the countless ages of the past, or which may exist in the countless ages of the future. Now, I am under no compulsion to think that the earth from all eternity has revolved around the sun, or that it will continue throughout all eternity so to revolve around the sun; in other words, I can help thinking that it always has travel- led, and that it always will travel, as it now travels. I can conceive the operations of the universe changed. This, therefore, is not a truth valid at all times for all intelligence. Take another case. I say, The square on the hypotenuse of a right-angled triangle is equal to the squares on the other two sides; or, to take a simpler case, I say that two straight lines cannot en- close a space. Are these truths which exist for all intelligence ? Yes, they undoubtedly are. Take the former: it is a truth which is valid for all intelli- gence. And why do I so regard it ? Simply because I am compelled. I cannot help thinking it as a truth which every intelligence which follows the demonstra- tion must assent to. And why can I not help thinking it to be a truth of this character ? Because I cannot conceive that any difference in the organism, or any difference in the constitution of the universe, or any difference in the intelligence which apprehends it, should cause it to be apprehended differently. I cannot conceive any mind which understands the de- monstration to hold that the squares on the two sides are either greater or less than the square on the thirdINTRODUCTORY. 23 side; and therefore I maintain that this is a truth valid not only for any intelligence, but valid for all intelligence; and that all mathematical truth, from the simplest axiom up to the most recondite conclu- sions, is of this character. 25. These observations (which have been somewhat hastily thrown together) are designed to contribute towards establishing this great and important conclu- sion, that the mind of man consists of a universal part as well as of a particular part, or of what we may call a universal faculty and a particular faculty. To pave the way for a right understanding of this distinction, I adduced these illustrative truths. The first was the truth that sugar is sweet; the second was that the earth goes round the sun; the third was (to take the simplest of the two cases) that two straight lines cannot enclose a space. Now, I have shown you that the first and second of these truths cannot be said to be true for all intelligences; and I have assigned the reason of this, which is, that either the constitution of the person who apprehends them, or the constitution of nature, can be conceived to be changed in so far as regards these truths, and that with the change, either in the constitution of the person or in the constitution of nature, the truth would cease to be true. Therefore they are particu- lar and relative. I have further shown you that the third of these truths can be declared true for all intel- ligence, because no change in the constitution of the24 GREEK PHILOSOPHY. person who apprehends it, no change in the constitu- tion of nature, can in any degree affect it. This truth, then, that two straight lines cannot enclose a space, is universal and absolute. Thus we have two sorts of truths; a particular order, comprising all the truths represented by our first and second truths, and a uni- versal order, comprising truths represented by our third truth. The particular order may be described as consisting of truths for some, but not for other, not for all, intelligences. The universal order may be described as consisting of truth for all intelli- gences. 26. What I have now particularly to call your attention to is, that just as there is one order or form of truth which is particular, and another order which is universal, so there is a faculty in man which is particular, and a faculty which is universal. The difference in the truths justifies us in maintaining a difference in the faculties or organs by which they are apprehended. We do not begin by finding that the mind has different faculties, but we begin by finding that the truths which the mind apprehends are very different in their character; that some of them are particular and relative, are truths merely for us; while others of them are universal and absolute, are truths for all intelligence; and in virtue of the objec- tive distinction, as we may call it, we postulate a subjective distinction in the mind which apprehends them. We declare that, in reference to the particularINTRODUCTORY. 25 truths, man has a corresponding particular faculty; and in reference to the universal truths, that he has a corresponding universal faculty. 27. This analysis I regard as the most fundamental distinction which can be drawn in the science of the mind. It lies at the root of the ordinary division of the mind into Sense, Understanding, and Eeason. If you were asked in what do these three differ, you would find it difficult to return a perfectly satisfactory answer. In regard more particularly to understand- ing and reason, you would find yourselves at a loss; for the difference between these two is what no psy- chology has as yet succeeded in explaining. But say that reason is the universal faculty, the faculty of truth as it exists for all intelligence, and that sense and understanding are divisions of the particular fac- ulty, that is, of the faculty of truth as it exists for some, but not for all intelligence, and light breaks in upon the distinction. You perceive that the faculty which is conversant with truth for all must be dif- ferent from the faculty which deals merely with truth for some; and perceiving that, you obtain an insight into the distinction between sense and understanding on the one hand, and reason on the other hand ; you begin to comprehend something of the constitution of your own mind, and also of mind universally. 28. I have just one more remark to make before I expand my definition of philosophy, by means of26 GREEK PHILOSOPHY. what I have said in regard to the universal faculty in man. It is obvious that this faculty must be the power, or seat, or place of necessary thinking, that is, of thoughts which we cannot help thinking, thoughts of which the opposites are pure nonsense; and in like manner it is obvious that the truths with which this faculty deals must be necessary truths, truths which cannot help being as they are, truths which cannot be otherwise than they are, and the opposites of which are pure nonsense. There is thus an objective necessity in truth, and a subjective necessity in thought, and the one of these corresponds to the other. For example, we say it is an objective necessary truth that two straight lines should not be capable of enclosing a space. And we say it is a subjective necessary thought that two straight lines should not be thought capable of enclosing a space. But what you have chiefly to attend to is, that wher- ever a necessary truth is apprehended, a truth which cannot be otherwise than it is, there the faculty of necessary truth, the universal faculty, comes into play, there necessary thinking takes place, there we think a thought which we cannot help thinking. 29. These considerations enable me to add some- thing to my definition of philosophy, and to give it out in the following terms, which are the most defi- nite, as well as the most complete, which I can at present devise. Philosophy is the pursuit of absolute truth, or of the absolutely real that is, of the true andINTRODUCTORY. 27 real as they exist for all intelligence; and this pur- suit is conducted under the direction of the universal faculty in man, or, in other words, is conducted under the direction of necessary thinking. 30. If you attend to the definition of philosophy which I have given you, you will perceive that it comprehends two important points: it states both what the truth is which philosophy pursues, and what the faculty is which is engaged in the pursuit. The first part of the definition declares what the truth is which philosophy pursues: it says that philosophy is the pursuit of absolute truth, that is, of truth as it exists for all intelligence. This may be called the objective part of the definition; it declares what is the proper object of philosophy. But the definition would be incomplete unless we added some- thing in explanation of the faculty by means of which the object of philosophy is to be attained. Therefore we subjoin:—And this pursuit is conducted under the direction of the universal faculty in man; in other words, is conducted under the direction of necessary thinking. Man's faculty of necessary thought is properly called his Eeason. So that the definition expressed shortly is this: Philosophy is the pursuit of absolute truth conducted under the direction of reason. But the definition under this compendious form expresses a mere vague truism, unless you keep in mind what we mean by absolute truth, and also what we mean by reason.28 GREEK PHILOSOPHY. 31. There is one difficulty which this definition leaves unresolved, and that is the question, Whether the truth of which philosophy is the pursuit be a hind of truth or an element of truth ; in other words, whether absolute truth can be apprehended by itself, or whether it must always be apprehended in union with relative truth ? In short, whether each, the ab- solute and the relative, is a form of truth which can be apprehended without the other, or whether each can be apprehended only in combination with the other ? This question I have considered under Pro- position VI. of my ' Institutes of Metaphysic,' where I have stated my own opinion, that the two must always be apprehended together. But as this is a point which can be settled only as the result of our researches, and as the whole history of philosophy shows that it is a very undecided question, I think it better to make no allusion to it in the definition, but merely to affirm that absolute truth is the object of philosophy, without saying whether absolute truth is a kind or is an element of truth. And, in the same way, I do not at present discuss or decide the question, whether reason be itself a faculty or merely an element of a faculty, sense being the other element which goes to make up the completed faculty. 32. Philosophy having been thus defined, we are now in a position to define the history of philosophy. This definition is very easily given—it follows as a matter of course. If philosophy be the pursuit whichINTKODUCTOKY. 29 I have described, the history of philosophy must be the history of that pursuit, and accordingly we define the history of philosophy as the history of the pursuit of absolute truth, or of truth as it exists for all intel- ligence ; and the history, moreover, of this pursuit, as conducted under the direction of the universal faculty in man, that is, under the direction of necessary thinking, or, more shortly, of reason. 33. These preliminaries being understood, the his- torian of philosophy ought now to have a tolerably distinct conception of the work which he has to take in hand. The task which he has to undertake is now apparent, although it may be beyond his power to execute that task even moderately well. It is ob- vious that the great business of the historian of phil- osophy must be to note and to point out how, and to what extent, philosophy, as manifested in its history, corresponds with philosophy as laid down in its defi- nition. It is obvious that if philosophy, as manifest- ed in its history, does not correspond at all—indeed, unless it corresponds to a very large extent—with philosophy as laid down in its definition, the defini- tion must be false. It is incumbent, therefore, on the historian of philosophy to show this correspondence. This is the principal work he has to perform. He must be able to show that the spirit of speculative inquiry when looked at in itself, is borne out by the spirit of speculative inquiry when looked at in its historical progress.30 GREEK PHILOSOPHY. 34. The definition of philosophy thus expresses the bond of union which unites the different sys- tems, and serves as a clue by which the progress of the historian may be directed. The historian may sometimes lose sight of this clue, at other times he may perceive it very indistinctly, but in general he will be able to trace it as a fine thread running through and binding together the different systems which come under his inspection. The clue, in short, on which he must fix his eye, is the circumstance, that the truth which philosophical systems aim at is absolute, and not relative, truth; that is to say, is truth as it exists for all, and not truth as it exists merely for some, intelligence. 35. The difficulty of following out this principle must be confessed to be great; and this difficulty arises mainly from the fact that the philosophers whose system we have to examine and estimate, never distinctly realised, or held clearly before their minds, that conception of philosophy which is expressed in our definition. Hence they frequently appear to be engaged in researches which have little or no con- nection with that pursuit which we have defined as the proper vocation of philosophy. They frequently appear to reach results which fall very far short of the absolute truth, results very different from those which we might expect philosophers to place before us. They frequently appear to entertain the most wayward and capricious opinions, instead of beingINTRODUCTORY. 31 guided by the strict necessities of reason. But if we keep in mind this consideration, that the moving forces of speculation, as of everything else, operate secretly long before they openly show themselves, we shall not consider it surprising that the outward ex- pression of philosophy should often differ extremely from its inward spirit; that its invisible life should often find a very inadequate exponent in its visible form; that the written letter should often indicate very imperfectly the unwritten meaning. It has only been by slow degrees that the mind of man has attained to a distinct consciousness of the right con- ception of philosophy as the pursuit of truth as it exists for all intelligence, and to the right concep- tion of the means to be employed in that pursuit, namely, necessary thinking. Yet there is sufficient evidence to show that both of these conceptions were at the bottom of the endeavours of the very earliest philosophers, and were the animating principle of their researches. 36. Nothing is more perplexing to the student of the history of philosophical systems than the oppo- sition to his ordinary modes of thought which these systems usually present. They seem quite alien from his ordinary ways of thinking. Their thoughts are not as his thoughts, and he cannot understand how their views of things should be so different from his. The explanation is, that while he is imbued with truth as it exists for his mind, with relative truth32 GREEK PHILOSOPHY. appealing to the particular part of his nature, these systems are aiming at the attainment and exhibi- tion of truth as it exists for all minds, of absolute truth, appealing to the universal part of man's nature. In these attempts they may be far from successful; but knowing what their aim is, and knowing that there must be a difference between truth considered as universal and absolute, ultimate and elementary, or truth as it is for all, and truth particular, relative, or as it is for some, we are in a position to compre- hend their drift and scope; and although they may fail to convince us, we shall in general be able to understand them. 37. For example, throughout the whole history of philosophy we find sensible knowledge held in but slight esteem. The truths of the senses are denied to be truths at all in the proper and strict accepta- tion of the word truth, and we are referred away to some other form of truth, of which no very clear account is given. To the young student of philos- ophy this is a most disheartening and perplexing procedure. He cannot understand why the truths of sense should be set aside as of little or no account, and why another set of truths, which seem to him far less satisfactory, should be brought forward in their place. And in no work, either on philosophy or on its history, does he find any very satisfactory reason assigned for this preference. But let him be told, and let him be called upon to consider, that the truths ofINTRODUCTORY. 33 the senses are not necessarily truths for all minds, but only truths for beings with senses like ours—are, in fact, only truths for some intelligences; and let him be further told, that the truth which philosophy aims at is the truth as it is for all intelligences; and he will be no longer surprised at the disparaging tone in which sensible truth is spoken of in the his- tory of philosophy. He may be of opinion that phil- osophy is wrong in this, inasmuch as he may think that all truth for man resolves itself into mere sensible truth. But whether philosophy be right or wrong, the student now understands distinctly the ground on which philosophy proceeds in holding as of little or no account the knowledge which comes to man through the senses. He sees that the reason why philosophy undervalues sensible knowledge is, that such knowledge is the truth only for some, but not for all intelligence. And he sees, further, that philosophy, if she is to be true to the terms of her own definition, not only may, but must, affix a brand on all sensible knowledge, stamping it as compara- tively invalid and irrelevant. CIONIC SCHOOL, thales. 1. I now proceed to consider the philosophy of Thales, if indeed the term philosophy may be applied to so meagre and barren a system. Thales and the other inquirers of the Ionic school appear at first sight naturalists (physici rather than philosophers). When these systems are looked at in their letter they seem to be entirely physical; it is only when their spirit is attended to that they can be pronounced to some extent philosophical. First, then, What did Thales regard as the ultimately real, the absolutely true ? For, as was formerly said, this is what philo- sophy undertakes, or at least endeavours, to ascertain. The determination of this question is identical with the search for unity amid multiplicity; in other words, is identical with an agency after some com- mon principle, which is the groundwork of all things, and which remains unchanged amid all the changes of the universe. What, then, according to Thales, is the ultimately real, the one in the many, the per-IONIC SCHOOL—THALES. 35 manent principle of the universe, the principle to which all intelligence must yield assent ? 2. Thales answers, that this principle is water ; that water is ultimately real—the groundwork and origin of all that is. It is probable that by the term water he did not mean the element under the ordinary and palpable form in which it is presented to our senses, but under some more subtle or. occult form of mois- ture or fluidity. 3. That water plays a most important part in the economy of nature is a truth too obvious to be over- looked. All the functions of animal and vegetable life depend on the presence of this agent, and it is scarcely possible to conceive the world subsisting without it. If any one element may be regarded as the parent of all that lives, as the condition on which the beauty and magnificence of nature depend, water has probably the best claim to be regarded as that element. Without moisture the universe would be a heap of ashes: add moisture, and the desert blossoms like the rose. These are reflections which could scarcely fail to present themselves to the ear- liest observers of nature; and, accordingly, we find that Thales gave expression to these reflections in the doctrine which announced that water was the principle and origin of all things. 4. Aristotle, commenting on the doctrine of Thales,36 GREEK PHILOSOPHY. confirms these remarks. In his Metaphysics (B. i. ch. 3) Aristotle says, that Thales was probably led to the opinion that water is the universal principle " from observing that all nourishment is moist, that heat is generated from moisture, and that life is sus- tained by heat. He observed that the seeds of all things were in their nature moist—this moisture they must derive from water; and hence Thales," con- tinues Aristotle, " held that water was the principle from which all things proceeded." 5. Aristotle then goes on to consider how far this doctrine of Thales may have been traditional. " There are some," says he, " who think that our very remote ancestors entertained theological speculations of the same character concerning nature. For they made Oceanus and Tethys the parents of generation; and water, under the poetical name of Styx, this they made the oath of the gods; for that which is the most ancient is the most respected; but the oath is the most highly respected of all things." The meaning of this is, that the gods swear by Styx, that is, by water; but the gods swear by what they respect most, but what they respect most is the most ancient and the most permanent of all things, in other words, is the ultimately real and true; and, therefore, water being that which they swear by must be the ultimately real and true. Thus, you observe that Aristotle traces the opinion of Thales ^up to a theological tradition respecting theIONIC SCHOOL—THALES. 37 oath of the gods. There is an old dogma, he says, that the gods swear by water; but what the gods swear by must be the most ancient, the most sure and steadfast—must be the ground of everything— the very kernel, as we may say, of the universe. Therefore, water must be the ground or kernel of everything. Thales translated into philosophy this old mythological tradition. 6. Here it naturally occurs to one to ask how Thales derived the various objects of the universe from the single principle of water? The only ex- planation offered is, that these diversified objects are formed by means of a process of thickening or of thinning, which water undergoes. Aristotle's words in reference to this process, although it is somewhat doubtful whether he is speaking of Thales when he uses them, are irvKvorr75 koX /lavorr}?, i.e., a thicken- ing and a thinning, a close consistency and a loose consistency. Water, when its consistency is loose, becomes vapour or air, when its consistency is still looser it becomes a fiery ether; in the same way thickened water becomes slime, and slime, when further condensed, becomes earth. In other words, the rarefaction of the watery principle yields air and fire; the condensation of the watery principle yields slime and earth, and out of the earth all things are produced. Water is thus a very Proteus, which pre- sents itself to us under manifold forms in all the objects we behold. What we call water is only one38 GREEK PHILOSOPHY. of these forms. Perhaps we may understand this by considering that it is really impossible to say what the proper form or peculiar nature of water is. Water fluid is water commonly so called; water solid is ice; water rarefied is vapour or steam, and no man can say that the one of these is more water than the other. We assume fluidity as the normal state of water, and reckon ice and steam deviations from this; but it would be just as correct to assume ice or steam as the normal state. 7. If we further ask how the machinery of the universe is originally set in motion—how this con- densation and rarefaction of water is brought about ? the only answer we obtain is, in the words of Diogenes Laertius (Lib. i. § 27), who says that, ac- cording to Thales, the world is animated and full of gods: or, in the words of Plutarch (De Placitis Phil, i. 7), who says that Thales has proclaimed God as the intelligent principle (i/ov?) of the world: or, in the words of Cicero (De Nat. Deor. i. 10), who says, "Thales Milesius . . . aquam dixit esse initium rerum, Deum autem earn mentem quae ex aqua cuncta fingeret;" i.e., Thales the Milesian asserted that water is the origin of all things, and that God is the presiding or quickening mind who formed all things out of water. 8. That Thales contended for some sort of uni- versal soul or life in nature is in the highest degreeIONIC SCHOOL—THALES. 39 probable; but that this soul was conceived by him as an intelligent principle, or that he inculcated the natural theology which Plutarch and Cicero gave him credit for, is disproved by the assertion of Aristotle, who says expressly that Anaxagoras, a philosopher considerably subsequent to Thales, was the first who held that intelligence was the principle of the uni- verse. Thales, therefore, cannot be held to have propounded a scheme of natural theology. 9. The philosophy of Thales reduces itself to the following five points: first, he contemplates the uni- verse from a physical point of view; secondly, he seeks for a principle of unity, he inquires after the common element, the primary and permanent essence of all things; thirdly, he finds this in something sensible and material, namely, in water or moisture; fourthly, he accounts for the various appearances of nature, for the different objects which the universe presents to us, by means of a thickening or a thinning of the original element, water—water is the substance, the essential, and these are merely its phenomena; fifthly, he ascribes to the universe a power of motion and of life by which the various changes that take place, and the various objects it contains, are pro- duced. These five heads embrace, I think, the whole philosophy of Thales, in so far as it is known to us. 10. The results of this system, when regarded as40 GREEK PHILOSOPHY. facts, are, it must be confessed, unsatisfactory enough. They are, indeed, utterly worthless. Considered as a statement of facts, the system has no interest what- ever, either physical or philosophical. The facts are not true, and the explanations explain nothing; but even though the facts were true, and the explana- tions explanatory, they would be of no speculative value, for they are merely a description of the uni- verse according to sense, and not according to reason. 11. To see any merit in this early system we must turn away from it in its dogmatic form; we must let it go as a statement of fact, and must look merely to its general spirit and tendency. When we look to this, we are able to rate at a higher value these ineffi- cient essays in philosophy. The very conception of reducing the diversified exuberance, the infinite pleni- tude, of nature to the unity of one principle, showed a speculative boldness which proved that a new in- tellectual era was dawning on mankind. To perceive that truth was to be found in the one, and not in the many, was no insignificant discovery. To be con- vinced that a thread of simplicity ran through all the complex phenomena of the universe was the inaugu- ration of a new epoch—was a great step taken in advance of all that had gone before—was, in fact, the very first movement which gave birth to science among men. This incipient generalisation, or tend- ency to generalise, as we see it put forth in these old philosophies, is the earliest attempt made by theIONIC SCHOOL—THALES. 41 mind of man to reduce to comprehension nature's infinite details; and as such it stands opposed, first, to the mythological spirit of those ancient times; secondly, to the ascendancy of the senses ; and, thirdly, it proves that the cogency of necessary truth was now beginning, although obscurely, to be appreciated. 12. I shall say a few words on each of these points separately. First, the spirit of generalisation, or the tendency to carry up the phenomena of nature to the unity of one principle, or to the simplicity of a few principles; this tendency is directly opposed to those old poetical dreams respecting nature, which gave birth to the Greek mythology. Mythology ran riot in a plurality or multitude of powers which it invoked, and to which it assigned the government of the universe; but philosophy, on the contrary, aimed at a unity of agency or causation in all things. In the old Greek mythology the number of divine agents (or celestial powers, greater and lesser) was infinite. While there was one general patron-god for woods and forests, each grove had, moreover, its presiding divinity; even each particular tree had its tutelar protector. There was one patron-god who presided over seas, rivers, and fountains; but each river and fountain had also its particular nymph, and I believe that I speak within the limits of the mythological spirit when I say that each individual wave floated its tiny god. The same may be said of every moun- tain and cave, and of every other natural object.42 GREEK PHILOSOPHY. Even the cloud-compelling Jove himself, even he owed his supremacy as the general father of gods and men, and as the general ruler of the universe, rather to the elevated region in which he was sup- posed to dwell, the summit of cloud-capped Olympus, than to the notion of any universal presidency which he exercised over all created things. Now, to these poetical fancies the philosophy of Thales, crude as it is, stands opposed. The mytho- logical disposition aims, we may say, at finding the manifold in the manifold. It is satisfied with the infinitude of nature, and makes no attempt to reduce her phenomena to finitude and unity. If it is ani- mated by the desire to reach the ultimately real, it is directed in this pursuit, not by the reason, but solely by feeling and imagination. Philosophy, on the other hand, aims at finding the one in the mani- fold. It attempts, by means of some principle, to reduce to unity the innumerable phenomena which press upon us from every side. Its researches are guided, not by the imagination, but by the reason. Even the philosophy of Thales evinces this tendency. It indicates a disposition of mind antagonistic to the mythological disposition, and therefore, meagre though it be, it is entitled to be regarded as the fountainhead of the great river of science which is now flowing through the world. Secondly, another point of interest to be foundIONIC SCHOOL—THALES. 43 in the philosophy of Thales, when we look away from the letter of the system, and regard rather its general scope, is that it stands opposed to the autho- ritative deliverances of the senses. That the mind of man should throw back and away from it the rich fulness and the diversified forms of sensible exist- ence, and should strive to reduce them all to one primitive element, this was a bold and a novel procedure. It showed that the mind, in its pursuit of the ultimately real, was beginning to emancipate itself from the ascendancy which the senses had hitherto exercised in determining its decisions. It showed that the senses were beginning to lose their authority as the criterion of ultimate truth, and that a tendency to appeal to a different tribunal, the tribunal, not of sense, but of thought or reason, was beginning to declare itself. It was not truth for some, truth acquired through the particular faculty, that was now aimed at, it was rather truth for all; truth to which every mind could and must respond, whether it had senses such as ours or not; truth, in short, for the universal faculty in our nature. This emancipation of the philosophic mind was carried, indeed, to no great length in the school of Thales and the other Ionic speculators. Sense, in fact, still remained the criterion of truth; all that can be affirmed is, that there was a tendency to rise to a different standard, the standard of thought and rea- son, in the settlement of philosophical questions —the tendency to find something which should44 GREEK PHILOSOPHY. be true for all intellect, and not merely for our intellect; and this tendency showed itself unmis- takably in the reduction of all sensible pheno- mena to one sensible principle — to wit, water, or moisture. But, thirdly, another important feature in the philosophy of Thales, when we look to its general spirit, is its recognition of the necessities of thought. It is founded on necessary thinking. There is, indeed, no necessity for our thinking that water is the unity, the common principle in all things; but there is a necessity for our thinking that there is some unity, some common principle in all things. This is what we cannot help thinking. It is a necessity of reason that we should think some central principle in all that is. There must be an element of agreement in all things. Because, to suppose two things absolutely and in all respects different from each other, would involve the supposition that one of them was a thing, and that the other was not a thing at all. But the supposition is that both of them are things, therefore they cannot differ absolutely, but must agree in some respect; and that respect in which they agree is their unity, their common quality, or as we frequently ex- press it, their universal. That there is a universal, then, a point of unity or agreement in all things, this is a necessary truth of reason. This truth is the basis of all intelligence, and the recognition of it is the basis of all philosophy. What the universalIONIC SCHOOL—THALES. 45 in all things is, is a very different question, and one not easily settled, as the whole history of philosophy shows. It certainly is not water, as Thales maintains. But that there is a universal, some common ground, in all things, this is a truth which forces itself upon us whether we will or not. It is no opinion, no arbitrary excogitation, but a thought which we can- not help thinking, a law or category binding on all intelligence. And the chief merit or value of the philosophy of Thales consists in its having recognised implicitly, for I cannot say that it did so explicitly, the necessity of this truth or law. 13. In estimating, then, the philosophy of Thales according to its general scope, we find the following points to be approved of as philosophical. First, this system inquires after the ultimately real. Sec- ondly, it is a substitution, to some extent, of philo- sophic thought in the room of the creations of fancy, inasmuch as it is antagonistic to the mythological manner of viewing things. Thirdly, it is a rejection, to some extent, of the authority of the senses as the criterion of truth, and it is the establishment, to some extent, of a new criterion; and, fourthly, it is founded implicitly, though not explicitly, on the recognition of necessary truth, inasmuch as it proceeds on the idea that unity, or a universal, is the ultimately real in all things. These four points contain, I think, all that can be called philosophical in the system of Thales; and these points are gathered not directly from the46 GREEK PHILOSOPHY. system itself, but are obtained by considering its general scope and tendency. 14. When we look to the system itself, when we try it by its letter and not by its spirit, in other words, when we regard it as a dogmatic statement of facts, it is seen at once to be exceedingly imperfect; to be destitute, indeed, of all philosophical value. There is no rational proof given, no sufficient evi- dence adduced, to show that water is the principle of all things. Still less is any rational explanation afforded as to how the various forms of actual exist- ence are evolved by means of a thickening and a thin- ning of water; and the system leaves us completely in the dark in regard to the active or formative energy by which things are produced. But, setting these imperfections aside, the two objections most fatal to the system are these : first, that the universal which it sets forth is a mere sensible universal; and, secondly, being such, it is not a true universal, not a universal at all. The consideration of these two points will conclude what I have to say on the phil- osophy of Thales, and will open the way for the system of his successor Anaximander, in which an attempt is made to obviate the objections referred to. You will thus perceive how the system of Anaximan- der is affiliated to that of Thales. This connection, this genesis of one system out of another, is in fact the most important matter to be attended to and kept in view in studying the history of philosophy.IONIC SCHOOL—THALES. 47 The first objection is, that the universal which the system of Thales sets forth is a mere sensible uni- versal. This is obvious from the consideration that, let us form what conception of water we may, we still think of it under some form of sensible representation. It is originally made known by the senses; and how- ever delicate and subtle the form may be in which we endeavour to construe moisture to our minds, it still retains, in our conception, to a greater or less degree, the form under which we originally appre- hended it. In other words, water or moisture is, in the first instance, an object of sense, a sensible pre- sentation ; and when we imagine it, or construe it to our minds, in the second instance, it is always a sen- sible representation. In regard to the second ground of objection, I shall merely remark that water, the universal principle of all things according to Thales, being a sensible uni- versal, is consequently not a necessary truth, not a truth for all intelligence, but only for those who are endowed with senses similar to ours. And conse- quently this system must be set aside as insufficient, inasmuch as it does not meet the requisitions of philosophy, philosophy being, according to our de- finition, that science which aims at the attainment of absolute truth, that is, of truth as it exists, not for some, but for all intelligence.48 GREEK PHILOSOPHY. ANAXIMANDER. 15. The next philosopher of the Ionic school was Anaximander. This philosopher was born in the year 610 B.C., and died in 547 B.C. Miletus was his birthplace, and he was the friend and disciple of Thales. He is said to have lived for some time in the island of Samos, at the court of the great Poly- crates, where also Pythagoras and the poet Anacreon were at that time residing. Anaximander is said to have been the first philosopher who put down his thoughts in writing. He made a map of the earth and the sea, in which it is probable that a good deal of conjecture was embodied. He invented the sun- dial, and was celebrated generally for his attainments in mathematics, and for his invention of mathemati- cal instruments. 16. The German historian of philosophy, Hitter, followed by Mr Lewes, takes Anaximander out of his place in the Ionic school, and connects him rather with the Pythagoreans. They do this on the ground that his speculations were rather mathematical than physical. It seems to me, however, that the position usually assigned to him as the immediate successor of Thales, and as a member of the same school, is his right place in the history of philosophy. And, accord- ingly, I have ranked him among the Ionic philoso- phers, both on account of his birthplace and of his phil-IONIC SCHOOL—ANAXIMANDER. 49 osophy, which seems to have been an attempt to de- velop and improve the system propounded by Thales. 17. The three following sentences from Diogenes Laertius, from Simplicius, a commentator on Aristotle, and from Aristotle himself, contain the substance of the philosophy of Anaximander, in so far as it has been handed down to us. Anaximander, they tell us, laid down the infinite or unlimited (to aireipov) as the principle and element of all things; and not any determinate matter, such as water, air, and so forth. This was his principle, because that which is the ground of all must be susceptible of receiving every form or variation. Accordingly, he assumed the infinite or indeterminate as a principle adapted to every species of production. " That indeterminate not being itself any particular thing, is capable of becoming any particular thing. This principle is itself without beginning, being the beginning of all other things; it embraces and governs all—it is the divine, the immortal, and the incorruptible/' Such is the substance of Anaximander s doctrine, as gathered from the three authors referred to. (Arist. Phys. iii. 4; Simplic. ad loc.; Diog. Laert., ii. 1.) 18. In explanation of these words, this may be added, that if we attempt to explain all things by means of a material principle or element, we can easily see that that principle must in itself be inde- terminate, without form or quality; for, suppose it D50 GREEK PHILOSOPHY. to be determinate, or to have a form, in that case it becomes one of the very things which call for ex- planation. In other words, the question instantly arises, Whence this determinate matter ? And sup- pose that the answer again is, It arises out of deter- minate matter, this determinate matter again requires explanation, and so on for ever, so that no approach at all is made to an explanation if, in explaining the origin of determinate or apparent matter, we are always referred to an antecedent determinate matter; and therefore, if this explanation of the origin of material things is to be held good for anything, we must ultimately be thrown in upon a matter which is altogether formless and indeterminate. This is the conception which Anaximander appears to have reached, and which he expressed by the term aireipov, the conception of a materia prima, a matter which, having no form or determination in itself, is capable of receiving all forms or determinations. That which is open to, and recipient of, all forms or qualities must in itself be invested with no form or quality, otherwise it would be foreclosed against the recep- tion of other qualities. 19. Such is the aireipov of Anaximander, in which we seem to find the germ of the distinction between matter and form, a distinction which afterwards be- came conspicuous in several schools of philosophy, and which, when construed into logic, became con- vertible with genus and difference ; genus was matter, \IONIC SCHOOL—ANAXIMANDER. 51 form was difference. The a7reipov of Anaximander was a 7TpcoTTj v\r), a first matter, from which all form or difference had been stripped, or rather to which no form or appearance was as yet appended, although Anaximander seems to have accorded to this matter a power of developing or secreting differences. 20. As an illustration of this conception, you may take the case of flour baked into bread. The bread, we shall say, exists as loaves and cakes in every variety of form. You explain these loaves and cakes as determinate flour, as flour determined or fashioned in a multiplicity of different ways. But then flour is itself something determinate, and therefore you will next be asked, What is flour the determination of ? What is its principle ? You must assign as its origin either something determinate or something indetermi- nate. If you assign something determinate (wheat, for example) as its origin, you are again asked, But what is the origin of the wheat ? Again your answer must yield something determinate or something in- determinate. If determinate, then the same question recurs, and your explanation goes for nothing. It has reached no ultimate, so that you are driven in the last resort to assign an indeterminate matter as the ulti- mate origin of the bread. This indeterminate matter is this matter without form, the anreopov of Anaxi- mander. 21. So far, then, the position of Anaximander is an52 GREEK PHILOSOPHY. advance beyond that of Thales. The principle of Thales (water, namely) was too definite and particular to serve as the common ground or basis of all things. Being already qualified, it was not open to all quali- fication. Anaximander thought that this objection was obviated by his aireipov. This, being unmodified in itself, was susceptible of all modification; being absolutely unconditioned, it was capable of becoming conditioned to any extent; and accordingly he adopt- ed this as his universal, and set it forth as the princi- ple of all things. The aireipov was perhaps the prosaic and philosophical name for the chaos of the poets. In the language of Ovid— " Ante, mare et tellus, et quod tegit omnia, coelum, Unus erat toto Naturae vultus in orbe, Quern dixere chaos, rudis indigestaque moles. Quaque fuit tellus, illic et pontus et aer : Sic erat instabilis tellus, innabilis unda, Lucis egens aer ; nulli sua forma manebat, Obstabatque aliis aliud, quia corpore in uno Frigida pugnabant calidis, humentia siccis, Mollia cum duris, sine pondere habentia pondus : Hanc Deus et melior litem natura diremit." 22. To this matter, originally indeterminate or unconditioned, Anaximander seems to have ascribed some inherent power of assuming form or of secreting differences, and thus the various objects of the uni- verse arose. The process is very insufficiently ex- plained. All that we can say is, that Anaximander's doctrine probably was that things have assumed the forms in which we behold them in consequence of certain affinities and certain repugnances pervadingIONIC SCHOOL—ANAXIMANDER. 53 the boundless and chaotic mass in which everything at first lay blended and enveloped. 23. The only two points, then, in the system of Anaximander seem to be these: first, the principle of all things, the universal in nature, the groundwork of the universe, the ultimately real and true, is, according to him, an unbounded, indeterminate, formless matter; this he calls apxv> beginning, and airetpov, the un- limited ; and secondly, to this aireipov he seems to have assigned some power of self-limitation, through which a shape was given to the different objects of the senses. 24. When we look to the mere letter of Anaximan- der's system, we find in it as little to satisfy the de- mands of reason as we found in the system of Thales, when embraced according to the letter. Even from the scope and spirit of the system we cannot gather much which is of philosophical or speculative value. Perhaps the chief merit of the system lies in its ten- dency to bring to light the opposition between the finite and the infinite. All true philosophy, I con- ceive, is based on a conception which conciliates, or reduces to one, these two, the finite and the infinite. But that this conciliation may take place, the opposi- tion between them requires first of all to be signalised. And Anaximander seems to have been the first in the history of philosophy who marked the distinction. Finite things, the various objects of the universe, these cannot be explained out of the finite. Such an54 GREEK PHILOSOPHY. explanation explains nothing, because it lays down, as the ground of the explanation, the very thing to be explained. The finite has to be accounted for. But it is certainly not accounted for when we say that the finite accounts for it. It is obvious, therefore, that the finite must be an outcome from the infinite, that is, its ground or principle must be the negative of the finite. The negative is a very important ele- ment of conception; it is essential to the very consti- tution of reason. Affirmation seems to be the moving principle of intelligence; but the power of negation is equally necessary; without this, intelligence could not work—all would be a blank. Anaximander seems to have been the first thinker who recognised the power and significance of the negative. His aireipov is the negative of the finite. But he does not carry out his own principle. The finite being con- vertible with the material, the right inference would have been, that the infinite, being the negative of the finite, was also the negative of the material, was the non-material; but Anaximander falls short of this conclusion. His anrupov, though the negative of the finite, is still regarded by him as some sort of form- less or unlimited matter. ANAXIMENES. 25. Of the life of Anaximenes, the third philoso- pher of the Ionic sect, we have little or no record. He was probably twenty or thirty years younger thanIONIC SCHOOL—ANAXIMEHES. 55 Anaximander, and may have been born about 590 B.C. He also was a Milesian. 26. As Thales had fixed upon water, and as An- aximander had fixed on the infinite or unbounded, as the universal principle, the ultimately real in all things, so Anaximenes fixed upon air as the common principle of the universe. Anaximenes thus fell back on the ground occupied by Thales, that is to say, he chose as his principle a natural determinate element. At the same time, by selecting an element less palp- able, less visible, less formed than water (air, namely), he seemed to aim at combining into one the principle of Thales and the principle of Anaximander. The principle of Thales was too sensible, too material, too definite, to be the universal in all things. The prin- ciple of Anaximander again was too indefinite to be comprehended. But air combines the two. It is suf- ficiently indefinite to be universal: it is sufficiently definite to be perceived and understood. It is, in short, a determinate infinite. Such appears to be the position occupied by Anaximenes in the philo- sophical genealogy which we are sketching. He at- tempted to effect a sort of compromise between the philosophy of Thales and the philosophy of Anaxi- mander. 27. In representing air as the essential and ani- mating principle of all things, Anaximenes appears to have made a nearer approach to the conception of56 GREEK PHILOSOPHY. mind, soul, or spirit, than had yet been made. We must remember that, although we are nowadays fa- miliar with these words, and attach to them some sort of idea, it was very different in these early times. Then no such words as mind, soul, spirit, and conse- quently no such conceptions, existed; and when such conceptions first began to dawn, they were clothed in words which originally signified breath or air (animus, spiritus, Trvevfjua—the original sense of these words is breath or wind): so important did air appear to the ancient framers of speech that they supposed it to be the sustaining and moving prin- ciple not only of our physical life, but of our intelli- gent and spiritual functions. 28. This opinion, which Anaximenes either adopted or originated, was carried out still further by his pupil, Diogenes of Apollonia, a city in Crete. This philo- sopher held that the air was itself sensible and intel- ligent ; and that it was through his participation in this ethereal principle that man both felt and under- stood—a doctrine which was revived at a late period by Campanella, a philosopher of the sixteenth century, whose works have fallen into more complete oblivion than they deserve. Campanella published a work, entitled 'De Sensu Eerum,' in which he contends that all nature possesses some sort of intelligence and sensibility, although it is only in man that this in- telligence and sensibility attain to self-consciousness. His reason for this opinion is given in these words:IONIC SCHOOL—ANAXIMENES. 57 " Quicquid est in effectibus, esse et in causis; ideoque elementa et mundum sentire " (' De Sensu Kerum'); which, with a little expansion, may be translated— " Whatever is in the effects, that is also in the causes. Man's sensations are the effects of the actions of the elements and the world, therefore the elements and the world are endowed with sensations/' But I shall say no more at present either about Campanella or Diogenes of Apollonia. I mention the latter merely in connection with Anaximenes, whose disciple he was, and as the fourth and last name in the older Ionic school which it is at all necessary to particu- larise. Heraclitus was also an Ionian, but he comes later, and is therefore not to be classed with the four of whose names and opinions I have endeav- oured to give you some account. 29. Without carrying further our exposition of these systems, and without entering on any detailed criticism of their merits or demerits, I shall just make this concluding remark: that these systems are truly philosophical, in so far as they aim at the attainment of a unity, a universal in all things, and in so far as they are animated and carried forward by the conviction, obscure and inexplicit though that conviction may have been, that the universal in all things is the ultimately real—is the truth for all in- telligence ; and that they aim at such a unity, and that they are, to a large extent, actuated and inspired by such a conviction, this, I think, is undoubted.58 GREEK PHILOSOPHY. So far they proceed under the direction of reason, of necessary thinking, and so far they are truly philo- sophical. But, on the other hand, they are truly un- philosophical in their details, or in their attempts to show what the universal in all things is. The true universal is certainly not water; it is certainly not formless or unlimited matter; it is certainly not air: for though we are under the necessity of thinking some universal in all things, we are not under the necessity of thinking this as water, or as formless matter, or as air; therefore these elements are not forced on our acceptance by any necessity of thought; therefore they are only relatively, and not absolutely, true, they are only truths for some and not truths for all intelligence: they are at the utmost merely truths for the senses and the understanding, not for the reason; they are merely disguised sensibles, and, as such, we cannot accept them as the veritable univer- sal of which philosophy is in quest.ITALIC SCHOOL, pythagokas. 1. The notices of the Pythagorean philosophy which have been transmitted to us, whether in its earlier or in its later manifestations, are scanty and extremely obscure. With the later manifestations we need not trouble ourselves. They are founded on spurious data, or at least on data which are not suffi- ciently authenticated. They are mystical in the ex- treme, and their symbolism is utterly incomprehen- sible. The earlier form of the philosophy, in so far as it is extant, is preserved in the fragments of Philo- ✓ laus, and in a few notices by Aristotle. Philolaus was a contemporary of Socrates, and flourished about 420 b.c. Aristotle was a good deal later: so that there was an interval of nearly a hundred years between Pythagoras, who was in his prime about the year 540, and the earliest expositor of his opinions with whom we are acquainted. These two, Philolaus and Aris- totle, are the principal sources of our knowledge of the Pythagorean philosophy in its earlier form. For60 GEEEK PHILOSOPHY. the later manifestations of this philosophy Sextus Empiricus, who lived in the first half of the third century A.D., must be studied. 2. Aristotle lays down the general principle of the Pythagoreans in the following terms: "Num- ber," he says, " is, according to them, the essence of all things; and the organisation of the universe, in its various determinations, is a harmonious system of numbers and their relations." " The boldness of such an assertion," says Hegel, " impresses us as very re- markable ; it is an assertion which strikes down at one blow all that our ordinary representations declare to be essential and true. It displaces sensible exist- ence, and makes thought and not sense to be the cri- terion of the essence of things. It thus erects into substance and true being something of a totally dif- ferent order from that form of existence which the senses place before us." (Werke, xiii. 237-38.) 3. What Pythagoras and his followers meant pre- cisely by number it is not easy to say. One point seems to be certain, that number, in the Pythagorean sense, denoted law, order, form, harmony. It is said that Pythagoras was the first who called the world /eooyxo?, or order, thereby indicating that order was the essence of the universe—that law or number, or proportion or symmetry, was the universal principle in all things. 4. If we compare this position with that occu-ITALIC SCHOOL—PYTHAGORAS. 61 pied by the Ionic philosophers, we shall perceive that it is an advance, an ascent, to some extent at least, from sense to reason. In fact, the great dis- tinction between sense and reason is now beginning to declare itself. To revert for a few moments to the Ionic philosophy. This philosophy is an advance on ordinary thinking; ordinary thinking is held cap- tive by the senses. It accepts their data implicitly, or without question. In the estimation of ordinary thinking, things are precisely as they appear: and their diversity is more attended to than their unity. In a word, ordinary thinking has eyes only for the particular, and is blind, or nearly so, to the universal. The Ionic philosophy rose into a higher position. It aimed at unity: it sought for a universal amid the diversity of sensible things; and this was an advance, a step in the right direction. The Ionic philosophy stood on a platform somewhat higher than that of ordinary thinking. But still this platform is far from being the platform of reason. The unity which the Ionic philosophers sought for among sensible things was sought for by means, and under the direction, of sense itself. It was a mere sensible universal; water, or infinite matter, or air; in short, it was something in itself material, and therefore something which, instead of being itself the universal in all things, did itself require to be brought under a universal, or re- duced to unity under a higher principle. It was, in fact, a particular universal, in other words, a contra- diction. The Ionic school, we may say, never rose62 GREEK PHILOSOPHY. above the region of sense, although within that re- gion they certainly rose into a stratum of atmosphere elevated above that of ordinary thinking. 5. Let us now pass to the Pythagorean philosophy. Whether the Pythagoreans emancipated themselves completely from the thraldom of the senses, or whe- ther such an emancipation be either practicable or desirable, I shall not now attempt to determine; but this is certain, that their speculations shot up higher into the region of pure reason than did those of their Ionic predecessors. Number is more an object of reason, and less an object of sense, than either water or air; and therefore we say that, while the position of the Ionic school is more that of sense than that of reason, the position of the Pythagorean school is more that of reason than that of sense. 6. Number is a truer universal than either water or air, or any other sensible thing. It is possible that the conception of number may not be an ade- quate conception of the universal in all things; that it may not be identical or coincident with the con- ception of the ultimately and absolutely real; but it is certainly a nearer approximation to this than any conception which we find set forth in the systems of the Ionic philosophers. The test of which is this: Suppose you had to explain something about the uni- verse to an intelligence different from man's, unless that intelligence had senses similar to man's, he couldITALIC SCHOOL—PYTHAGOKAS. 63 not understand what you meant by water, or air, or earth, or fire, or colour, or sound, or heat, or cold: but whatever his senses were, or whether he had any senses or not, I conceive he would understand what you meant by number, he would know what one meant, and what many meant. He would not under- stand intuitionally what a tree was, and he could not be made to understand it intuitionally: but he might understand it symbolically, by being informed that it and everything else was a unity which admitted of being resolved into multiplicity, and that each of the fractions was again a unity. Unless he could be made to understand this—in short, unless he could form some conception of number—it seems to me that he would not be an intelligence at all. And there- fore it may be said that number is a true universal, that is to say, it is a necessary thought; it expresses something which is the truth for all, and not merely the truth for some, intelligence. At any rate, it is a wider and truer universal than either water or air, or any other sensible thing. 7. We are now able to understand the appar- ently very paradoxical assertion of the Pythagoreans, namely, that number is the substance of things, the essence of the universe; and we are able, moreover, to perceive in what sense this doctrine is true. The whole paradox is resolved, the whole difficulty is cleared, by attending to the distinction to which I have so often directed your thoughts, the distinc-64 GREEK PHILOSOPHY. tion between truth for all, and truth for some, or otherwise expressed, the distinction between the uni- versal faculty in man, and the particular faculty in man. If we hold that the substance of things is to be found in that which is the truth for some, in other words, that it is to be apprehended by the particular faculty in man, in that case we shall certainly not hold that number is the substance of things; on the contrary, we shall hold that earth, or water, or air, or matter generally, is the substance of things, because this is what falls under the apprehension of the par- ticular faculty in man. But if we hold that the sub- stance of things is to be found in that which is the truth for all, that the essence of things centres in that which is the truth for all intelligence, in other words, that the essence of things is to be apprehended by the universal faculty in man; in that case we shall certainly not hold that earth or water, or matter generally, is the substance of things, for this is not necessarily the truth for all intellect; on the other hand, we shall experience no great difficulty in hold- ing that number is the substance of things, because number is the truth for all, and is that which falls under the apprehension of the universal faculty in man. You can thus readily understand the Pytha- gorean doctrine, even though you may be not quite willing to assent to it, that number is the essence of the universe, the ultimately and absolutely real. Number is this, because- number is the truth of the universe for all intelligence; matter and its qualitiesITALIC SCHOOL—PYTHAGOKAS. 65 are not the essence of the universe, not the ulti- mately and absolutely real, because they are not the truth for all, but only the truth for some intelligence, that is, for intelligence constituted with senses like ours. 8. To clear up this philosophy still further, it is right that I should state to you the grounds on which I hold that number is an object of reason, that is, of the universal faculty in man; in other words, is an object of all reason, and is not an object of sense, or of the particular faculty in man; in other words, is not an object merely of some intelligence. My reason, then, for holding that number is an object of pure thought rather than of sense is this; that every sense has its own special object, and is not affected by the objects of the other senses. For instance, sight has colour for its object, and can take no cog- nisance of sound. In the same way hearing appre- hends sound, and takes no cognisance of colour. In like manner we cannot touch colours or sounds, but only solids. Neither can any man taste with his eyes, or smell with his ears. If number, then, were an object of sense, it would be the special object of some one sense; but it is not this. It accompanies our apprehension of all the objects of the senses, and is not appropriated to any sensible objects in particu- lar. It is not, like all the other objects of sense, the special object of any one sense, and therefore I con- clude that it is not an object of sense at all, but an E66 GREEK PHILOSOPHY. object of thought or reason. When we look at one colour, what we see is colour, what we think is one, i.e., number; when we look at many colours, what we see is colour, what we think is many, i.e., num- ber. This distinction, the distinction by which num- ber is assigned to reason, and not to sense, is, I think, an important aid towards understanding the Pytha- gorean philosophy. 9. Number is a necessary form of thought under which we place or subsume whatever is presented to the mind. Hence form, which is another name for number, and not matter, is the essence of all things, at least of all intelligible things. It is the truth and substance of the universe—its truth and substance, not only in so far as it exists for us, but in so far as it exists for intelligence generally. Without number they are absolutely incomprehensible to any intelli- gence. Take away number, that is to say, let the universe and its contents be neither one nor many, and chaos, or worse, is come again. We are involved in contradictory nonsense. Number, then, or form, and not matter, as the Ionic philosophers contended; number, and not the numberless, or direopov of Anaxi- mander, is the true universal, the common ground, the ultimately real in all things. With Pythagoras form or number is the essential, matter the unessen- tial: with the Ionics matter is the essential, and form or number the unessential. In their respective positions the two schools stand diametrically opposed.ITALIC SCHOOL—PYTHAGORAS. 67 But the Pythagorean is certainly a stage in advance of the Ionic. 10. In the account which I have hitherto given you of the Pythagorean philosophy, I have taken the statement of its principle from Aristotle, and, found- ing on his text, I have endeavoured, by means of a few critical reflections of my own, to impart to it some intelligibility, and to show you that there is some meaning, and also some truth in the assertion, that number is the essence of all things. I go on to speak of the Pythagorean philosophy as represented by Philolaus. Philolaus was probably the first of the Pythagoreans who committed to writing any of their master's doctrines; for neither the founder of the school, nor his immediate disciples, appear to have put their opinions on record. Philolaus was, as I said, a contemporary of Socrates. He wrote a work on the Pythagorean system, with which Plato seems to have been acquainted. Some fragments of this work are extant, and were collected and published in 1819 by a German scholar, Augustus Boeckh. 11. In this work we find these words: "Every- thing," says Philolaus, "which is known has in it num- ber, for it is impossible either to think or know any- thing without number." He thus makes number the source and condition of intelligence, and the ground of the intelligible universe. But the following is68 GREEK PHILOSOPHY. even more important: " It is necessary," says Philo- laus, "that everything should be either limiting or unlimited, or that everything should be both limiting and unlimited. Since, then, it appears, that things are not made up of the limiting only, nor of the un- limited only, it follows that each thing consists both of the limiting and the unlimited, and that the world, and all that it contains, are in this way formed or ad- justed." This is a remarkable extract, for it shows that the Pythagoreans had to some extent anticipated the great principle of Heraclitus, namely, that every thing and every thought is the unity or conciliation of contraries; a principle, the depth and fertility of which have never to this day been rightly appre- hended or appreciated, far less fathomed and ex- hausted. 12. In his dialogue entitled Philebus, Plato touches on this Pythagorean doctrine. For the word irepaivov- ta, which is Philolaus's expression for the limiting, he substitutes Trepan, the limit; and the union of the two (the limit and the unlimited) he calls /jllktov, the mixed. So that, according to Pythagoras (and Plato seems to approve of the doctrine), everything is con- stituted out of the Trepas, and the airetpov, the limit and the unlimited, and the result is the /jllktov, that is, the union of the two. This principle, afterwards ap- plied to morals, led to Aristotle's doctrine of the fieao- T779, or of virtue as a mean between two extremes. The 7repa? in the physical world was a limit or law im-ITALIC SCHOOL—PYTHAGORAS. 69 posed on the infinite lawlessness of nature: the Trepa? or /-teeroTT?? in the moral world was a limit im- posed on the infinite lawlessness of passion. 13. To get a little further insight into this matter, let us consider the conception of the fjuacrov. This, I conceive, is equivalent to the limited. Now, let us ask what it is, in any case, that is limited ? Perhaps you will say that it is the limited that is limited. But that would be an inept answer. What would be the sense of limiting the limited, the already limit- ed? That would be a very superfluous process. Therefore, if the limit is to answer any purpose, it must be applied, not to the limited, but to the unlimited; and this, accordingly, is the way in which the Pythagoreans apply it. The limit is an element in the constitution of the limited; the un- limited being the other element. 14. Here is another way of putting the case. Take any instance of the limited, any bounded or limited thing, a book, for example. No one can say that the book is without limits. The limit, then, is cer- tainly one element in its constitution. But is the limit the only element ? Does the book consist of nothing but limits ? That certainly cannot be main- tained. There is something in the book besides its mere limits. What is that something? Is it the limited ? Clearly it is not; because the limited is the total subject of our analysis; and, therefore, to70 GREEK PHILOSOPHY. hold that the limited is the other element, would be equivalent to holding that the whole subject of the. analysis was a mere part or element of the analysis. The limited (the book) is what we are analysing, and therefore it would be nonsense to say that the limited was one factor in the analysis, while the limit was the other factor. This would be analysing a total thing into that total thing and something else. But if the limited cannot be the other term of the analy- sis, that other term must be the unlimited. What else can it be ? The limited, then—in this case the book — consists of the limit and of the unlimited, and these are the two elements which go to the con- stitution of everything. Suppose the limits—for example, the two ends of a line—taken away, and no ends left, that which would remain would be the unlimited. But that cannot be conceived, you will say. Certainly it cannot. But it can be conceived to this extent, that if that part of a line which we call its ends or limits be taken away, and no new limits posited, then the remaining part, considered in and by itself, is necessarily the unlimited. This element, which truly cannot be conceived without the other element, is the anreipov of the Pythagoreans; and it cannot be conceived for this reason, that con- ception is itself constituted by the union or fusion of these two elements, the limit and the unlimited. Such is the Pythagorean doctrine, and it seems to me to be not only perfectly intelligible, but also perfectly true.ITALIC SCHOOL—PYTHAGOKAS. 71 15. Another form which the Pythagoreans em- ployed to express their principle was the expression fiovas, the one, and aoptaro9 St>a?,'the indeterminate or indefinite two. Of these terms, the latter, in parti- cular, is very obscure, and has been very insufficiently explained. I will endeavour to throw what light upon them I can out of my own reflections. First of all, these terms seem to be merely another form of expression for the irepas and the airecpov; the fjuova9 or one is the Trepas or limit; the aopicrros Svas is the aireipov, the unlimited and indeterminate. Every-1 thing in being limited is one. This is expressed by the term iiovas, which stands for the sameness or identity in things; but the diversity of things is inexhaustible; and this capacity of infinite diversity is indicated by the term aoptaros Svas, indefinite difference; so that, according to the Pythagoreans, the general scheme of the universe, as regarded by pure reason, is identity, combined with a capacity of infinite diversity. Nei- ther of the terms has any meaning out of relation to the other. But let us for a moment consider each term by itself; aopicrTos 8va$, taken by itself, stands for absolute diversity. Everything in the universe is absolutely different from every other; all things are particular, and they are held together by no universal. The aopuGTo? Sua?, in short, signifies, when taken by itself, the unbounded and inexhaustible particular. The fiovas, again, taken by itself, stands for their unity; it signifies their feature of agreement. In a word, it is their genus, just as the aopicTos hvm is a72 GREEK PHILOSOPHY. general expression for their difference. Mova9 is the Pythagorean term for the universal; aopLcrros 8va$ is the Pythagorean term for the particular; and neither of these is capable of being conceived with- out the other. The true conceivable limit, whether considered as a thought or a thing, is the result of their combination. 16. We shall perhaps get more light thrown on these terms if we consider them under a purely arith- metical point of view. It might be thought that these words, irova? and aopicrro5 Bvas, simply signified one and two, or one and indeterminate two. But that is not at all the meaning which the Pythagoreans attached to them. According to the Pythagoreans, every number consisted of these two parts; the /nova? and the Sua? were not numbers, but were the mere elements of number. This seems a perplexing posi- tion, yet it is susceptible, I think, of explanation. For example, every number is different from every other number; 1 is different from 5, 5 is different from 10, 10 is different from 20, and from 100, and so on. But every number also agrees with every number; and in what respect is it that all numbers agree ? They all agree in this respect, that every number is once, or one times that number, whatever it may be; 5 and 10 and 20, and so on, agree in being once 5, once 10, and once 20. Each of these is one times what it is, so that they all agree in con- taining the fjbovhs, or one. If you were to say five, orITALIC SCHOOL—PYTHAGOKAS. 73 five ones, and did not mean once five, or one times five ones, your words would have no meaning. Nei- ther you yourself nor any one else would know what you meant. But when you say once five, and then once ten, you not only express an agreement, you also express a difference between five and ten. Now, the general term for this difference is aoptaro? Sua?, and this Sua? or diversity is said to be aopMrro? or indefi- nite, because it varies indefinitely—once 10, once 20, once 30, once 40, once 1000, once 1,000,000—the once term, the fiovas, never varies, but the other term, the Sua?, as expressed hy 20, 30, 40, 1000, 1,000,000, varies indefinitely, and its variations are inexhaust- ible ; hence it is called aopwTos. Perhaps the simplest translation of aopiaros would be the indefinite any ; aopio-Tos Sua?, any particular number. I conceive that in this way the Pythagorean doctrine, that the /-torn? and the aopio-Tos Sua? are the elements of number, may be explained. Neither is the number one any exception; it, too, is composed of the jiova? and the aopiaros Sua?. One, like all other numbers, is differ- ent from any other number. In what respect does it differ from all other numbers ? It differs from them in being one. In what respect does it agree with them ? It agrees with them in being once one, or one times one, or one one. When we say " one," we usually mean " one one;" but we do not always or necessarily mean this, but may just as well mean 100 or 1000. One, viewed strictly, stands for once any number; and therefore, when it stands for the74 GREEK PHILOSOPHY. numerical one, it should be, and it is, construed to the mind as one one. One one, then, is the first arithmetical number, and, if so, we must be able to show that its elements are the /iora? and the Sua?; for these are, according to Pythagoreans, the elements of all number without exception; and this can be shown without much difficulty. One one: which word, in that expression, stands for the monad, the point of agreement in all numbers ? The first one does so. We say one one, one five, one ten, one hun- dred. All these numbers agree in being one—i.e., once what they are. Then, again, which word in the expression one one, stands for the duad—the diversity, the point in which one one differs from all other num- bers ? The second one does so. One one, one Jive, one hundred. The second word in each of these expres- sions expresses the difference of each of these num- bers. One one is different from one five in its second term, but not in its first. From these remarks it ap- pears, I think, that even number one is no exception to the Pythagorean law, which declares that the ele- ments of all number are the monad and the duad, and that these are not themselves numbers. Thus, by con- sidering numbers, we obtain light as to the constitu- tion of the universe. Everything in the universe has some point in which it resembles everything else, and it has some point or points in which it differs from everything else ; just as every number has some point in which it resembles all other numbers, and some in which it differs from all other numbers.ITALIC SCHOOL—PYTHAGORAS. 75 17. The monad and the duad being the elements of number must be viewed as antecedent to number. There is thus a primary one which is the ground or root out of which all arithmetical numbers proceed. And there is also a primary duad from which num- bers derive their diversity. These two enter into the composition of every number (even into the com- position of the numerical one), the one of them giving to all numbers their unity, or agreement, or identity; the other of them giving to all numbers their diversity. The primitive numbers, the numbers an- tecedent, as we may say, to all arithmetical numbers, are the Pythagorean monad and the Pythagorean duad. Of these, the former expresses the invariable and universal in all number; the latter, the variable and particular. And inasmuch as the particular is inexhaustible and indefinite, the duad is called aopiaros or indeterminate. Better to hold them ele- ments of number than numbers. 18. As an illustration of the spirit of this phil- osophy, let me show you how a solid, or rather the scheme of a solid, may be constructed on Pythagorean principles. Given a mathematical point and motion, the problem is to construct a geometrical solid, or a figure in space of three dimensions, that is, occupy- ing length, breadth, and depth. Let the point move —move its minimum distance, whatever that may be; this movement generates the line. Now let the line move. When you are told to let the line move,76 GREEK PHILOSOPHY. your first thought probably is that the line should be carried on in the same direction—should be pro- duced ; but you see at once (the moment it is pointed out to you) that such a movement is not a movement of the line, but is still merely a movement of the point. You cannot move the line, then, by continu- ing it at one or at both ends. To move the line you must move it laterally. That alone is the movement of the line. The lengthening of the line is, as I said, merely the movement of the point. The move- ment of the line then generates a surface. Now, move the surface. Here, too, you must be on your guard against continuing your lateral motion, for that is merely a continuation of the motion of the line; and this is not what is required. You are required to move not the line, but the surface; you must therefore move the surface either up or down into the third dimension of space, namely, depth; and these three movements give you the scheme of solid. You have merely to suppose this scheme filled with visible and palpable matter, that is, with something which is an object for the particular faculty in man, to obtain a solid atom; and out of atoms you can construct the universe at your discretion. 19. It seems at first sight a marvellous piece of foolishness that a philosopher should ascribe to empty unsubstantial number a higher degree of reality than he allows to the bright and solid objects which constitute the universe of matter. The ap-ITALIC SCHOOL—PYTHAGORAS. 77 parent paradox is resolved when we consider the kind of truth which the philosopher is in quest of. He is not searching for truth as it presents itself to intellects constituted in a 'particular way, furnished, for example, with such senses as ours. If that were what he was in quest of, he would very soon find what he wanted in the solid earth and the glowing skies. But that is not what he is in quest of. He is seeking for truth as it presents itself to intellect universally, that is, to intellect not provided with human senses. And this being his aim, he conceives that such truth is to be found in the category of number, while it is not to be found in stocks and stones, and chairs and tables, for these are true only to some minds, that is, to minds with human senses; but the other is true to all minds, whatever senses they may have, and whether they have any senses at all or not. Slightly changed, the line of Pope might be taken as their motto by the Pythagoreans, "We think in numbers, for the numbers come." They come whether we will or not. Whatever we think, we think of under some form either of unity or multiplicity. Number seems to be a category of reason and universality. 20. This explanation seems to relieve the Pytha- gorean principle from all tincture of absurdity, and to render it intelligible, if not convincing; admit that truth and reality are rather to be found in what78 GREEK PHILOSOPHY. is true for all minds, than in what is true for some minds; and admit further, that number is true for all minds, and that material things are not true for all minds (but only for minds with senses); and what more is required to prove that truth and reality are rather to be found in number than in material things ? The whole confusion and misapprehension with which the Pythagorean and Platonic, and many other systems, have at all times been overlaid, have their origin in an oversight as to the kind of truth which philosophy aims at apprehending. Philos- ophers themselves have seldom or never explained the nature of the end which they had in view, even when they were most intently bent on its attainment. Hence they seem to run themselves into absurdities, and hence their readers are bewildered or repelled. But let it be borne in mind that the end which phil- osophy pursues is the truth as it exists for intellect universal, and not for intellect particular—for intel- lect unmodified, and not for intellect modified—for intellect whether with senses like ours, or with senses totally different; and the apparent paradoxes of the Pythagorean and other ancient philosophies will be changed generally into articles of intelligible belief, and will stand out for the most part as grand and unquestionable verities, at any rate, as nearer ap- proximations to absolute truth than anything which the mere senses can place before us.ELEATICS. xenophanes. 1. This sect derived its name from the town where its principal philosophers resided, Elea or Yelia, a Greek settlement in southern Italy. The leaders of the Eleatic sect were Xenophanes, Parmenides, and Zeno, to whom may be added Melissus. The general character of this school is, that its speculations rose into a higher region of abstraction or pure thought than those either of the Ionic or of the Pythagorean philosophers. While the tendency of the Ionic inquirers was physical, and while that of the Pytha- goreans was mathematical or arithmetical, the Elea- tic sect may be characterised as dialectical in their procedure.

At this time the art of prose writing had not begun to be cultivated. The opinions and senti- ments of Xenophanes were accordingly delivered in verse. He seems to have been a composer and reciter of various kinds of poetry, some fragments of which have been preserved in the writings of Athen- aeus, Sextus 'Empiricus, and some other ancient authors. These relics have been collected, along with those of Parmenides, by Karsten, a Dutch scholar, and were published by him in 1830. 4. The doctrines of Xenophanes were rather theo- logical than speculative. One of his principal aims was to disabuse the minds of his countrymen of the ideas about the gods which had been instilled into them by the poems of Homer and Hesiod. In his opening fragment he proclaims a doctrine of mono- theism, and- condemns anthropomorphism, or that creed which fashions God after the likeness of men.

Of this being he says: " Without labour he governs all things with the power of reason," airavevdeELEATICS—XENOPHANES. 81 7tovolo voov p€vl itclvtcl KpaZaivet. " Men, however," he adds, " imagine that the gods are born, are clothed in our garments, and endowed with our form and figure. But if oxen or lions had hands, and could paint and fashion things as men do, they too would form the gods after their own similitude, horses making them like horses, and oxen like oxen." He then finds severe fault with Homer and Hesiod on account of the disgraceful actions which they attri- bute to the gods, and strongly reprehends the pre- valent superstition in regard to the generation or genealogy of the gods. Aristotle refers to this (Ehet. ii. 23), where he remarks, " It is a saying of Xenophanes that those who assert that the gods are born are equally impious with those who maintain that they die. For both equally affirm that there is a time when the gods are not." But opposed as Xenophanes was to the popular superstitions, and anxious as he was to correct them, he professes him- self unwilling to dogmatise about the gods or about anything else. "For," says he, "naught is with certainty known; mere opinion cleaveth to all things—So/co? 8' iirl ntclctl reTy/crai" 5. Nevertheless, in his philosophy, of which I now proceed to speak, he aims, to some extent at least, at certainty and truth. The great distinction or anti- thesis around which the whole Eleatic philosophy revolves and gravitates is the antithesis of the one and the many, the permanent and the changeable, F82 GREEK PHILOSOPHY. the universal and the particular, in Greek, the ev and the nroWd. This antithesis is merely a variety of expression for the antithesis between reason and sense. Or, if we may distinguish between the two forms of the opposition, we may say that the one ex- pression, the permanent and the changeable, or the ev and the TroWd, denotes the antithesis in its objec- tive form; the other expression, reason and sense, denotes the antithesis in its subjective form. 6. To adjust rightly the terms of this fundamental antithesis, to determine the nature of the relation which subsists between its two extremes, is the main problem of the Eleatic philosophy. We have to consider, then, how Xenophanes its founder went to work. Xenophanes seems to have dwelt more steadily than any other philosopher, whether Ionic or Pythagorean, on the conception of the one or of unity as the essence of all things. His con- ception of unity as the principle of the universe and as a primary necessity of thought seems to have been more determinate than that of any of his pre- decessors or contemporaries. He held that the one was everywhere; and Aristotle adds, that Xeno- phanes, looking forth over the whole heavens, that is, the universe, declared that the one was God.* The first position of Xenophanes, accordingly, is that there is a unity in all things, and that this unity is God. It is in and through God that the universe is a universe, that is, has unity.ELEATICS—XENOPHANES. 83 7. Another predicate of unity is permanence. The unity which is God is also the permanent and un- changeable, that is to say, it is exempt from genera- tion and corruption. It cannot be born or produced, for that which is produced proceeds either from that which is the same as itself, or from that which is not the same as itself. But the permanent cannot pro- ceed out of what is the same as itself; because this being already the permanent, cannot produce or give rise to the permanent. Neither can the permanent proceed out of what is not the same as itself; for this would be the production of the positive out of the negative—the generation of Being out of not- Being, and a violation of the Eleatic axiom, Ex nihilo nihil fit Or, more shortly stated, the reasoning of Xenophanes is this: What is, or the permanent, cannot arise out of what is, or the permanent, be- cause the two are identical. Again, what is, or the permanent, cannot arise out of what is not, or the non-permanent, because what is cannot spring from what is not. Nonentity has no power of generation. The one permanent and unchangeable, the unity in all things, or, according to Xenophanes, God, this principle is from everlasting to everlasting. This is the ground of all, the ultimately and absolutely real. This alone is the certain and the true. 8. Such being the primary position of Xenophanes and the Eleatics, a question arises in regard to the other member of the fundamental antithesis of84 GREEK PHILOSOPHY. which I spoke, namely, the changeable. What does this school of philosophy say about that ? Change or "motion" (which was the generic word usually employed by the older systems to denote every species of change), this was too obtrusive and pro- minent a feature in the constitution of things to be overlooked. It is in dealing with this question that the dialectical, i.e., the logical and metaphysical, character of the Eleatic school reveals itself. It is here for the first time that the dialectical movement of human thought comes distinctly into play. In the Ionic school the adjustment of the relation be- tween the unchangeable and the changeable was not attempted at all, or attempted after the crudest fashion. In the Pythagorean school the conciliation of the one and the many was rather taken for granted than discussed and explained. They either ignored or touched but lightly on the problem and the diffi- culties which it involved. The Eleatics, I say, were the first who seriously addressed themselves to its consideration. And it is on this account, in part at least, that their school has been characterised as dialectical or logical and metaphysical, while the Ionics were characterised as physical, and the Pytha- goreans as arithmetical and mathematical. 9. When we take up this question—the question in regard to the relation between the unchangeable and the changeable, the one and the many—what first strikes us is the repugnancy of the two termsELEATICS—XENOPHANES. 85 of the antithesis. The antithesis is ultimate or fundamental, that is to say, there is nothing higher than it in the region of thought, no higher cate- gory under which these two extremes may be con- ciliated or reduced to unity. It denotes a radical and thoroughgoing opposition. This, at any rate, is the point of view from which at first we are compelled to regard it, and this is the point of view from which Xenophanes and the other Eleatic philosophers re- garded the antithesis. The necessities of thinking seemed to them to declare that the distinction was absolute and irreconcilable. A strict logic seemed to necessitate this conclusion. 10. But now observe what follows from this con- clusion. This follows from it, that whatever epithet or predicate is applied to one of the terms of the an- tithesis, the counter-predicate must be applied to the other term. Unless this were so, the opposition would not be absolute and complete. It follows, then, that if we call the unchangeable, or the one, true, we must call the changeable, or the many, untrue; that if we call the unchangeable, or the one, real, we must call the changeable, or the many, unreal. In short, if we say that the one, the permanent, or the unchange- able, is, we must say that the many, the fluctuating, the unchangeable, are not Such was the logic by which the Eleatic school found themselves compelled to maintain the nonentity (the comparative nonentity at least) of all sensible existence. For it was the86 GREEK PHILOSOPHY. data of sense, the universe as apprehended by the sense, it was this which constituted the changeable element in the fundamental antithesis with which they had to deal. 11. This dialectical movement—a movement not urged against them by their adversaries, but one forced upon them by the logical necessities of their position, and one to which they readily yielded—this movement comes more to the surface in Parmenides and Zeno than it does in Xenophanes. But it showed itself to some extent in Xenophanes, and in him we first find an implied though not explicit severance made between the intelligible world and the sensible world, between the world of reason and the world of sense, and the former represented as the sphere of reality, the latter as that of unreality. 12. Xenophanes did not hold that there was no sensible world; no idealist ever maintained that, although we shall see by-and-by that under the stricter interpretation of his system Parmenides is forced to such a conclusion. But I say Xenophanes did not hold that there was no sensible world. He held, however, that it had no reality, no reality in itself, but only a reality in and for the mind of man, which reality was, in fact, no reality at all. It was a mere subjective phenomenon, and possessed no such truth as that which reason compelled us to attribute to the permanent one, which, according toELEATICS—XENOPHANES. 87 Xenophanes, was God. His tenets on this point may be illustrated as follows: Suppose that the sun is shining on the sea, and that his light is broken by the waves into a multitude of lesser lights, of all colours and of all forms; and suppose that the sea is conscious, conscious of this multitude of lights, this diversity of shifting colours, this plurality of dancing forms.; would this consciousness contain or represent the truth, the real ? Certainly it would not. The objectively true, the real in itself, is in this case the sun in the heavens, the one permanent, the persistent in colour and in form. Its diversified appearance in the sea, the dispersion of its light in a myriad colours, and in a myriad forms, is nothing, and re- presents nothing which substantially exists, but is only something which exists phenomenally, that is, unsubstantially and unreally, in the sea. Take away the sea, and these various reflections no longer are. This dancing play of lights is a truth only for the sea, not a truth for the land; there the light falls differently; therefore it is not a universal truth, and nothing in strict philosophy being admitted as true which is not universally true, it is not, strictly speak- ing, a truth at all. Such is the way in which we may suppose Xenophanes to illustrate his position in regard to sensible existence. This form of exist- ence has no existence in and for itself no existence irrespective of the mind and the senses of man, no existence at all resembling that which must be con- ceded to the one, the permanent and the real; but an88 GREEK PHILOSOPHY. existence in all respects the opposite of this, and there- fore an existence in all respects unreal and untrue. 13. Finally, we may say of Xenophanes that he seems to have approximated more nearly than had yet been done to the realisation of what may be called a double consciousness; a rational conscious- ness, on the one hand, cognisant of the permanent One, as positive existence, as the real and true in itself; and a sensible consciousness, on the other hand, cognisant of the changeable many, as negative existence, as unreal and untrue in itself, and as pos- sessing, in comparison with the genuine and absolute reality of the unchangeable one, only a spurious and relative reality. Keep well in mind the thorough- going repugnancy between the one and the many, the intelligible and the sensible, inculcated in this school; remember that whatever predicate is applied to one member of the antithesis, the opposite predi- cate must be applied to the other member of it, and you will obtain a clue to the doctrines of these phil- osophers, and will understand, however hard you may find it to agree with, their dogmas in regard to sen- sible existence, and the phenomena of the material universe. PARMENIDES. 14. I pass on to Parmenides. This philosopher is the central figure in the Eleatic sect, a man of impos- ing presence and authoritative aspect. His personalELEATICS—PARMENIDES. 89 influence on his contemporaries was powerful and ex- tensive, and the shadow of his great name stretched down through many generations of antiquity, inspir- ing reverence and wonder. In the dialogue of Plato entitled ' Thesetetus/ Socrates, speaking of Parmeni- des, says: " This man appeared to me, if I may use Homer's language, to be at once august and com- manding (ucre&)?, concerning nature. The poem opens with an allegory, the lite- ral meaning of which is, that the poet, impelled by his passions, goes in quest of truth. At first the senses are his guides. At length he reaches a spot where the gates stand which open on the paths of truth and of error. AUrj, that is, justice, or wisdom, or understanding, is the guardian of the gates. She receives him favourably, and points out to him which is the road of reason and truth, and which the road of sense and opinion, bidding him follow out the one and avoid the other. The pathway of inquiry, she says, is twofold: the one way is that which affirms being and denies not-being; this is the way of truth and reason: the other is, the way which denies being and affirms not-being; this is the way of error and sense. The following is a translation or paraphrase of a few of the lines; the horses which bear him along are the passions, the nymphs are the senses: " Far as the mind can reach conveyed me impetuous horses, Speeding along God's highway, which runs through the secrets of nature. Nymphs directed my course, the nymphs of the sun were my escort;ELEATICS—PARMENIDES. 91 Issuing from chambers of darkness, they threw back the veils from their foreheads. At length 1 came to the spot where the gates of light and of darkness Stood; and there stood Justice, holding the keys that unlock them. Blandly addressed her the nymphs, and blandly answered the goddess, Opening the gates with her keys, so that the chariot might enter. Then, taking me by the hand, she spoke these words of assurance : i O youth, borne from afar to my house by the horses that brought thee, Led by omens of good, thou hast come to the dwelling of "Wisdom. I will show thee the way it behoves thee to follow devoutly ; ^Also the road of appearance, where nought but fallacy reigneth. Come, then, this is the true road, which says that Being alone is, And that not-Being is not: whereas the pathway of falsehood Teacheth that not-Being is, and that Being immutable is not. On the first of these roads thy mind may travel securely ; But if it enters the second, 'twill be lost in the mazes of error.' " —Karsten, i. 2, p. 28. 17. Such, in translation, is an imperfect specimen of a somewhat imperfect poem, a poem which, even if it had come down to us entire, would present few points that would be readily intelligible to our modern apprehensions. The first part of the poem, which is entitled Ta irpos akrjdeiav, that is, "concerning truth," continues to ring the changes upon truth as that which centres in Being, Being one and immutable, Being not apprehensible by the senses, but only by the reason. It also describes falsehood as centring in not-Being, as the multifarious, the particular, the sensible, the non-existent, and the inconceivable. The poem has a second part, not very consistent with the first, entitled Ta irpos Sogav, that is, " concerning92 GREEK PHILOSOPHY. appearance or opinion." In this part the poet-phil- osopher makes some attempt to describe and explain the phenomena of the sensible universe. In addi- tion to the tenets propounded in this poem, we find in Plato's works, particularly in the dialogue entitled 4 Sophista,' some notices of the speculations of Parmenides, and the other Eleatics, respecting Being and not-Being. But these speculations must be worked out mainly by means of one's own reflec- tions. We have only a few crumbling bones from which to construct our skeleton as we best may, and to give it, if that be possible, some semblance to tlie remains of an organic creature. 18. The whole philosophy of Parmenides centres, I think, in these two points; first, the conception of Being; and, secondly, the determination of the rela- tion between Being and not-Being. Let us consider each of these points separately. 19. First, then, of the conception of Being. To set forth Being as the universal, as that in which all things are identical, to declare that Being is the truth of the universe; this, to us, who live in these latter times, may seem to be a very trivial and unin- structive dogma. But we have to remember, for one thing, that we, as soon as we were born, have entered on an inheritance of thoughts and of words from which these early thinkers were altogether cut off. They had to think out and to devise what we findELEATICS—PARMENIDES. 93 already thought out and devised to our hand. What we pass by as rubbish, because we are so familiar with it, was, in its first revelation, a divine spark which enlightened the irrational darkness of man's original nature, and bespoke the presence of a rea- soning and reflective mind. This consideration may serve to explain how the conception of being should appear to us to be at once the shallowest, and yet should be, in itself, the most fundamental and essen- tial of all the conceptions of reason. But there is this also to be considered. There is this question to be asked: How far does the philosophy which sets up Being as the universal principle, how far does it tally with our definition of Philosophy; the defini- tion which declares that philosophy is the pursuit and attainment of truth as it is for all, and not merely as it is for some intelligence ? I conceive that this philosophy of Parmenides corresponds, if not adequately, at any rate largely, with our definition. Being is not the truth of the universe for our minds, or for any minds in "particular; but it is the truth of the universe for all minds. Being is a necessary conception, a conception valid for all reason. An intelligence which had no conception of Being could not be an intelligence at all. Attempt to explain to an intelligence with no such senses as ours—attempt to explain to him the sensible universe, the universe as it appears to the senses, and he would not under- stand you. But tell him that the universe is, that it has Being, and to the extent of that conception he94 GREEK PHILOSOPHY. would understand you. He would understand you because he necessarily knows and understands that his own thought is. He would understand what you meant by Being (remember I am supposing him to be an intelligence, and therefore able to think, although he has no such senses as ours); he would understand this, because the thought of being is itself being. Being, then, is a wider universal—that is to say, it is more a truth for all intellect, for intel- lect in its very essence—than any principle set forth in the Ionic school, than water, or infinite matter, or air. It is a wider universal even than number, the principle of Pythagoreans. It may possibly be a ques- tion whether an intelligence might not work without thinking number; but it can be no question whether an .intelligence can work without thinking Being. Deprive it of this category, and you annihilate its intelligent functions. It may turn out hereafter that Being is only a half category, only half a neces- sary thought. Meanwhile, however, we accept it as a necessary conception of reason (without inquiring whether it be a whole or only a half conception); we accept it as a true universal, as that in which all has unity, as a truth valid for all intellect. And we regard the system of Parmenides, in which this truth was first enunciated, as a true philosophy, inas- much as it comes up, to some extent at least, to the standard of our definition. 20. Secondly, of the relation of Being and not-BeingELEATICS—PARMENIDES. 95 as determined by the system of Parmenides. Here we find the fundamental antithesis of which I have spoken carried out by the dialectic movement of thought into its most extreme opposition. This antithesis has come before us as the universal and the particular, the intelligible and the sensible, mat- ter and form, the one and the many, the permanent and the changeable: it now comes before us as Being and not-Being. This is a form into which the antithesis is inevitably forced, forced by a logical necessity. If the one term be Being, the other must be not-Being, otherwise it would be the same term over again, and there would be no antithesis. What- ever the one member of the antithesis be, the other must be its direct opposite; otherwise the antithesis would not be fundamental, it would have its founda- tion in a higher unity. Bun over each pair of terms. Here the particular is obviously the non-universal; if it were the universal there would be no antithesis; there is no antithesis between the universal and the universal. The particular, then, is the non-universal, and we may express the opposition as the universal and the non-universal. In the same way the intelli- gible and the sensible is equivalent to the intelligible and the non-intelligible; matter and form is equiva- lent to matter and not-matter; the one and the many is equivalent to the one and the not-one; the perma- nent and the changeable is equivalent to the perma- nent and the not-permanent. So likewise, when we make Being one of the terms of the antithesis, it96 GREEK PHILOSOPHY. must be faced by not-Being as the other term; no- thing else would yield an opposition. We cannot oppose Being to Being; and therefore not-Being is the only counter-term to Being. 21. The antithesis, then, of the one and the many, the intelligible and the sensible, the permanent and the changeable, has passed in the Eleatic school into that of Being and not-Being. The next movement of thought in dealing with this relation is the question, Does not-Being exist ? Is there any not-Being at all ? It is difficult, I believe it is impossible, to state in precise terms how the Eleatics answered this question. In the first part of his poem Parmenides seems to maintain that there is no not-Being; in the second part of it he accords to not-Being a sort of spurious existence. In fact, answer the question in either way, and the difficulties that arise are insuperable. Suppose, in the first place, we say that there is no not-Being, then the whole material world, all sensible existence, is annihilated, for this is not-Being. The world of sense stands logically opposed to Being in the fundamental antithesis of thought, as the par- ticular to the universal, the sensible to the intelligible, the many to the one. This solution, then, which abol- ishes the one member of the antithesis, abolishes like- wise the material world. The other member, Being, to wit, alone is left. And what sort of universe is this ? It is a universe in which there is no plurality, no diversity, no difference of one thing from another,ELEATICS—PARMENIDES. 97 no motion, no change anywhere, nothing but a dead immovable uniformity. The many is identical with not-Being; there is no not-Being, therefore there is no many, but only one. The changeable is identical with not-Being; there is no not-Being, therefore there is no changeable, but only an unvarying permanent. The universe, according to reason, is evidently in a quandary. Mere Being can never change, because there is nothing to change it. But may not Being be added to Being, and may not change be the result of the synthesis ? No, there cannot be a synthesis of only one element. Being added to Being is merely a repetition of one and the same factor, and nothing can come of that, nothing can emerge in the shape of a new product. The universe of the Eleatics having been reduced to one homogeneous element, Being namely—i.e., the universal without the par- ticular—has in it no change, no variety, no life; it is mere stagnant undiversified unity. That is the difficulty which the Eleatics have to face when they maintain that there is no not-Being at all. 22. Suppose then, again, Parmenides to admit that, in some sense or other, not-Being exists. The ques- tion is, in what sense ? It is difficult to see that this can be admitted in any sense without running into a contradiction. The admission, however, if allowable, would save the phenomena of the material universe. So much may be conceded. For, suppose it were urged against Parmenides that, in identify- GGREEK PHILOSOPHY. ing sensible existence with not-Being, he had anni- hilated the former, his answer would be; No: I do indeed identify sensible existence, or the material world, with not-Being; but then I hold that not-Being has a sort of existence (spurious enough, I grant you, but still a sort of existence), and therefore the ma- terial universe, which is identical with not-Being, has a sort of spurious existence. That answer, I say, would be sufficient to save the material world and its phenomena from the logical extinction which would overtake them under the other alternative. In conceding this, however, I am not sure, on second thoughts, that I have not conceded too much. Let us investigate a little more closely this spurious kind of existence which, under one interpretation of his system, Parmenides attributes to the presentations of sense. It will be found, I think, that this kind of existence, instead of being merely spurious, is contra- dictory, and is obtained in defiance of all the laws of logical thinking. We must revert for a moment to the fundamental antithesis of Being and not-Being. Vjn his search after unity Parmenides found Being. This he constituted into a world by itself, a world apart. This is_th^_one.^ But there is also the not- one or the many, and this is not-Being. But if the one or Being be constituted into a world by itself? the many or not-Being must likewise be constituted into a world by itself; you cannot isolate one thing from another without isolating that other from the first. But what happens when the world of not-BeingELEATICS—PARMENIDES. 99 is isolated from the world of Being ? This happens, that the particular is prescinded from the universal; you are called upon to conceive particulars under the presidency of no universal; in other words, you are called upon to conceive a contradiction. The spurious existence which we supposed might be attri- buted to not-Being, and therefore to natural things, is a mere subterfuge, which, when examined, resolves itself into a contradiction. I don't say that such an attribution is inconsistent with the principles of every philosophy, but it is certainly inconsistent with the principles of the Eleatic philosophy; for this philosophy makes no attempt to conciliate the two members of the antithesis of which I have so often spoken, but, on the contrary, does all it can to draw them asunder into their widest opposition. And therefore it perishes beneath this twofold con- tradiction. The world of Being (the intelligible world of the Eleatics) is a contradiction to all rea- son, because it is the sphere of the universal pre- scinded absolutely from the particular; and the world of not-Being (the sensible world of the Ele- atics) is also a contradiction to all reason, because it is the sphere of the particular prescinded absolutely from the universal. In the one world there is abso- lute unity without any diversity; in the other there is absolute diversity without any unity, and neither of these can be conceived. 23. In summing up the philosophy of Parmenides,100 GREEK PHILOSOPHY. I would call your attention to the distinction between sense and reason, which appears to be more distinctly announced in his system than in any other that had preceded. I am not aware that he calls X0709 or rea- son the faculty of truth for all, and 86%a or the faculty of truth for some; but this is evidently his meaning, this was the substance of his distinction between \0709 and aiadrja^) the latter he did not con- sider to be properly the organ of truth at all, but only the former. The main points of detail in the system are these: First, Being is the universal, the element in which all things agree. This is apprehended by reason. Secondly, The particular or non-universal in things is not-Being. This is apprehended by sense. Thirdly, No attempt is made to conciliate, but rather to separate absolutely, the members of this antithesis. This separation of the antithesis necessarily preceded the conciliation of the antithesis, otherwise there would have been no antithesis at all. Fourthly, The consequence is that the universe of Parmenides falls asunder into two contradictories, a world of unity on the one hand, where there is no diversity, and a world of diversity on the other hand, in which there is no unity. Fifthly, His attempt to save the material phenomena by attributing to not-Being a spurious Being (if indeed he does make this attempt) is alto- gether unsuccessful; for he has carried Being wholly over into the intelligible world, and therefore the sensible world, or the world of not-Being, cannot on his principles have any Being at all conceded to it.ELEATICS—PARMENIDES. 101 Sixthly, The two contradictories which have been explained break down the system of Parmenides. 24. The philosophy of Parmenides, meagre as its principle, and unsatisfactory as its issues may seem, is a genuine product of the speculative spirit of the world straining towards the light. It is a true phil- osophy ; it has its roots in the necessities of thought. It goes forth in pursuit of the universal, the truth for all intellect. It finds this in the conception of Being; but it mistakes a half conception for a whole one, so that, instead of establishing a whole, it only establishes the half of a necessary thought: in other words, it issues in a contradiction. Nevertheless, this philosophy is great, great in itself, greater in its effects on succeeding thinkers. It is no arbitrary excogitation of an individual mind. It is a product of the universal reason grappling with the universal truth. It represents a speculative movement common to the understandings of all thinking men, a move- ment through which every mind that reflects must inevitably pass, a catholic crisis in the development of thought itself. It is indeed their broad catholicity, their unindividual thinking, their speculating for the race, or rather, I may say, for all intelligence, and not for themselves, which gives to these old philosophers their interest and value. In this respect Parmenides must be ranked among the highest of those wide and essential souls through which the universal reason has expressed, although not adequately, its everlast-102 GREEK PHILOSOPHY. ing laws, and given an articulate shape to the thoughts that wander through eternity. ZENO. 25. Zeno, like Parmenides, was a native of Elea. If we may believe Plato, he was twenty-five years younger than Parmenides. Both of them are said to have taken an active part in the administration of the affairs of their native city. Zeno was a resolute opponent of tyranny, and is reported by some autho- rities to have died a martyr in the defence of liberty. • 26. Zeno is styled by Aristotle the father and founder of dialectic; and if the evolution of the issues contained in the philosophy of Parmenides entitle a man to this appellation, he deserves it well. Zeno was the author of those subtle and paradoxical puzzles respecting motion, the solution of which has for the most part baffled logicians even down to the present day. These puzzles, which ought not to be regarded as quibbles (although this is the light in which they are usually looked at), are full of deep significance as illustrative of the laws and progress of thinking. They show how thought is absolutely at variance with itself, and thus, by bringing the oppo- sition fairly to the surface, they prepare the way for its ultimate conciliation under the presidency of a higher principle. Some of the paradoxes are ex- pressed in the words, " Achilles can never overtakeELEATICS—ZENO. 103 a tortoise "—" the flying arrow rests." And generally the impossibility of motion is the leading paradox in the philosophy of Zeno. I may touch upon some of these hereafter: meanwhile, I shall make a few remarks on the principle on which he founds, and on the difference between him and Parmenides. 27. The only difference between Parmenides and Zeno seems to be this, that the one of them argued the affirmative and the other the negative side of the same question. Parmenides took the affirmative side, and argued that Being, the one alone, truly existed. Zeno took the opposite side, and argued that not-Being, the many, had no true existence. The dialectical movement of thought, namely, the oppo- sition between the one and the many, Being and not- Being carried to an extreme, this is, of course, in both cases the same. But if we are to make a distinction between the procedure of Parmenides and that of Zeno, the distinction which I have now pointed out to you is the one which we must draw. 28. In what I have as yet said I am not sure that I have quite reached the ultimate foundation on which the Eleatic philosophy rests. At least I am not sure that I have given it sufficient prominence, or distinguished it with sufficient clearness from the collateral considerations that went along with it. I shall now attempt to make these ultimate points clear, because it is only by getting thoroughly to the104 GREEK PHILOSOPHY. root of the matter that we can understand either the motive or the character of the Eleatic speculations. To express their principle, then, almost in one word, it is this: that opposite determinations cannot be combined in the same object, that contrary predi- cates cannot be assigned to the same thing. They hold, for example, that what was one could not be not-one, i.e., many; and that what was many or not- one could not be one. They held that what was universal could not be non-universal, i.e., particular; and that what was particular or non-universal could not be universal. They held that what was intelli- gible could not be non-intelligible, i.e., sensible; and that what was non-intelligible or sensible could not be intelligible. The same rule was applied to their own ultimate generalisation of Being and not-Being. What was Being could not be not-Being, and what was not-Being could not be Being. What was could not not be, and what was not could not be. To Being, the one, the universal, the intelligible—the predicate not-Being could not be applied; and to not-Being, the particular, the sensible, the many—the predicate of Being could not be applied. In short, the incom- patibility of opposite predicates or determinations attaching to the same subject, this is the ultimate foundation, the fundamental position, of the Eleatic philosophy. 29. Now, the question here arises, a question, how- ever, which I shall merely broach without discus-ELEATICS—ZENO. 105 sing; the question, Are contrary, opposite, or, as I will call them, contradictory determinations incom- patible in the same subject? If they are, then I hold that the philosophy of the Eleatics must be accepted with all its consequences. There is no escape from the paradoxes of Zeno if this principle be true. And, certainly, at first sight it appears not only to be true, but to be forced upon us as true by the very necessities of reason. It seems to be a necessary truth of thought that a thing cannot be one and not one, cannot be universal and not univer- sal, cannot be infinite and finite, and, in fine, cannot be and not be: and, accordingly, this principle has been recognised as a necessary truth in most of the schools of philosophy, even by those which abjure the conclusions of Parmenides and Zeno. Reserving this question for subsequent discussion, I may just here remark that this principle, so far from being a necessary truth of reason (however like one it may look), is, on the contrary, a downright contradiction, an absurdity to all reason; and that its opposite, namely, the principle that opposite determinations are not only compatible in the same subject, but are necessary to the constitution of every subject—this is a necessary truth of reason, is, in fact, the law of the universe, the law of the universe of things as well as of the universe of thought, and that its discovery and enunciation rest with Heraclitus. 30. Reserving for a future opportunity what I106 GREEK PHILOSOPHY. have to say on Zeno's subtle paradoxes in disproof of motion, and also his position that opposite predicates or attributes cannot attach to the same subject, I shall now offer a short summary of the Eleatic philosophy. The general scope and substance of the Eleatic philosophy may be summed up under the following heads:—First, the Eleatic philosophers assumed Being, and nothing but Being, as their universal, their truth for all reason; this with them was the to ovf or the real. Secondly, they denied or discarded the opposite of this, to erepov or to /jltj ov, the not-Being. Thirdly, they denied this on the ground that the same thought or the same thing could not contain or consist of opposite determinations or con- trary predicates. Fourthly, the consequence was, that there was no diversity, no plurality, no difference, no life, no generation, and no decay; in short, no change or movement in the universe, according to them; nothing but a dead and unvarying uniformity, a stagnant fixedness, more inanimate than nonentity itself. Being, according to Parmenides, was strictly synonymous with the permanent. Hence his con- clusion followed at once: the world of Being is the world of permanence. In the world of permanence there is and can be no change, otherwise the per- manent would not be the permanent; therefore, in the world of Being there is and can be no change. Or it may be put in this way, the world of Being excludes not-Being; not-Being is essential to change; there- fore, the world of Being excludes change. To under-ELEATICS—ZENO. 107 stand how not-Being is essential to change you have but to consider that all change is the cessation, or putting off, or not being of one state or determina- tion, and the putting on or being of another state or determination. But in the world of Being there can be no not-Being of any state or determination, because this is the sphere of pure unmixed Being, and not-Being is absolutely excluded from it. And, therefore, inasmuch as not-Being is absolutely ex- cluded from this sphere, and inasmuch as not-Being is essential to constitute change, it follows that all change is necessarily excluded from this sphere. In other words, in the world of Being there is no change, no creation, no becoming; that is, no coming into Being and no going out of Being; there is a mere dead unvarying uniformity. That is the world of reason and of truth according to Parmenides; and it is fairly, indeed inevitably, reached upon his prin- ciples, which are, that the world of Being and of not-Being stand towards each other in a relation of irreconcilable antagonism, and that opposite deter- minations cannot belong to, and may not be predicated of, the same subject. 31. Let us now consider shortly the position of Zeno. In the world of change there is no Being. This is the same thesis viewed negatively. Parmen- ides showed that what is, cannot change; and his ground or fulcrum of proof was, that Being excludes not-Being, and not-Being is essential to change; for108 GREEK PHILOSOPHY. instance, the not-Being of solidity is essential to the Being of fluidity. On the other hand, Zeno proves that what changes, cannot be; and his fulcrum is that not-Being excludes Being. To repeat his posi- tion : in the world of change there is no Being. The proof is this : if the world of change included Being, it would include the permanent, because Being and the permanent are identical; but the permanent is excluded from the changeable by the very terms of the conception, therefore Being is excluded from the world of change ; in other words, in the world of change there is no Being, Such is the negative supplement by means of which Zeno reinforced the positive argument of Parmenides- In the sphere of Being, or the one, the universal, says Parmenides, there can be no not-Being (and consequently no change), because to introduce not-Being here would be to assign opposite determinations to the same subject. And in the sphere of not-Being, the many, the particular, says Zeno, there can be no Being (and consequently nothing but change), because to intro- duce Being here would, in like manner, be to assign opposite determinations to the same subject. The reasonings of the Eleatics are impregnable if their principle, namely, that contrary determinations can- not belong to the same subject, be conceded.HEKACLITUS. 1. It may help to keep distinctly before your minds the chief characteristic or distinction of the various systems we have been considering, if we designate by one word the principle for which each of them contends. They are all searching for the common quality or feature, what we call the universal, in all things, something which is true for all minds. If they can attain to this, they conceive that they have reached the ultimately real, the absolutely true. According to Thales, then, water was the universal; according to Anaximander, infinite or indefinite matter was the universal; air was the universal of Anaxi- menes. According to the Pythagoreans, number was the universal principle; while, with the Eleatics, the universal in all things was being. 2. We now come to a philosopher who inaugurated a new era in speculation. Heraclitus comes upon the scene; and the universal for which he contends is movement, change. This principle is different from all those which have been enumerated. It is indeed110 GREEK PHILOSOPHY. more distinct from them all than they are distinct from one another. It therefore marks a new crisis in the development of philosophy; so that while we may class the previous systems together under the general title of the philosophy of Being, inasmuch as they all deal in some way or other with Being, we place the system of Heraclitus under a different head, and designate it as the philosophy of Becoming. This is the only word in our language which corre- sponds to the povr)crL<;, lays hold of relative truth, truth as it exists for some, that is, for man con- sidered as a peculiar intelligence. It is through the koivos \6yo$ that we apprehend Becoming as made up of Being and not-Being. The understanding and senses could never make known to us this truth, they lead us away from its recognition. In virtue of sense and understanding, the IBca (frpovrjo-Ls, we regard the universe as a stationary existence, subject, no doubt, to changes; in virtue of reason, the kolvos X070?, we regard it as a continual alternation of Being and not-Being, and we see that the latter no less than the former is essential to the ongoings and con- stitution of nature, considered as a constantly vary- ing and never resting process. 30. Before offering a summary of the system of Heraclitus, I may say just one word on the scope of138 GREEK PHILOSOPHY. his ethical speculations. The substance of his ethi- cal doctrine is this, that man lives and acts rightly in so far as he lives and acts in conformity with the Koivos X0709, the universal reason in which he parti- cipates, but which does not properly belong to him; and that he lives and acts wrongly in so far as he lives and acts in conformity with the Ihia cftpovrjcris, or that part of his nature which is more properly his own. The koivos X0709, when its behests are obeyed, leads him away from his own private and personal aims; it lifts him above the sphere of his own selfish interests, and teaches him to think of something far greater than himself: the Ihia fypovrjais, when it is yielded to, binds him down within the sphere of his own selfishness, and makes him regard his own private advantage as the' great and sole end of his existence. Thus viewed ethically, the /coivos X070? may be called the great moral law, the IBca (frpovrjaii; may be called " man's own conceit." Heraclitus thus seems to have been the first moralist who identified man's true moral nature with the universal faculty in man, and man's wrong and immoral nature with his particular faculty. This ethical doctrine comes much more fully to light under the treatment of subsequent moralists, and therefore I shall content myself at present with having merely broached it for your consideration. 31. In my summary of the philosophy of Heracli- tus, I shall endeavour to point out the relation inHEBACLITUS. 139 which his system stands to the philosophy of the Eleatics. First, then, the main themes with which both he and they were engaged in their attempts to reach and fix the absolute truth were Being and not- Being. Both parties agreed in fixing their attention on these two; but they differed in this respect, that whereas the Eleatics regarded Being and not-Being as distinct and separate conceptions, and as irrecon- cilable opposites mutually exclusive of each other, Heraclitus regarded them but as elements or mo- ments of one conception, the conception, namely, of Becoming. Such very shortly, is the fundamental agreement and the fundamental difference between Heraclitus and the Eleatic philosophers. What they regarded as distinct conceptions, he regarded as the factors of one conception. 32. This being understood, the second point to consider is this, that with the Eleatics Being is the truth, Being is the universal principle, Being is the intelligible for all intellect; while, with Heraclitus, Becoming is the truth, Becoming is the universal principle, Becoming is the intelligible for all intel- lect. Being, say the Eleatics, is a necessary truth, a thought which all intellect must think. Not so, says Heraclitus; it is Becoming which corresponds to this description; and Becoming embraces Being merely as one of its elements, not-Being forming the other moment of that conception. Now, you will observe that Heraclitus, in taking up this position against140 GREEK PHILOSOPHY. the Eleatics, does not deny altogether the truth of their principle. He does not deny that Being is a necessary truth, a truth for all intellect. He rather admits this. But he holds at the same time that it is only a half thought, and not a whole thought. It is a half conception, which requires to be supple- mented by its other half, the factor, namely, called not-Being. The unity of these constitutes the true and total conception; and that true and total con- ception is expressed by the term Becoming. 33. In the third place, to decide between these conflicting parties, Heraclitus on the one hand, and the Eleatics on the other; to determine the merits of their respective principles, and to get some insight into their systems, we must observe how these prin- ciples work, and how far they are explanatory of the changing phenomena of the universe. The Eleatic principle will not work at all. This system comes instantly to a dead-lock; or rather it cannot get under way. for it is impossible to explain change, if we hold asunder Being and not-Being, and regard them as two separate conceptions. The more we reflect on it the more are we convinced of this impos- sibility. Consider; a thing is in a particular state, which state is its being. Call this state A. I wish it to change; I wish to get it into some other state, call it B. But to get it into the state B, I must get it out of the state A; to put on B it must put off A. I shall suppose, then, that I get it out of the state A,HEKACLITUS. 141 that it puts off A. Is it now in the state B ? has it put on B or any other state ? It certainly has not; for you will observe that, just as the Being of A is a separate conception from the not-Being of A, so the not-Being of A is a separate conception from the Being of B—that is, of any other state. The thing, on the terms of this philosophy, is in no state at all. It has ceased to be A, but it has not got into B. It is an intermediate predicament of pure negation or nonentity, a predicament which we can only characterise by calling it the not-Being of A, and the not-Being of B; B standing for any other positive state. In short, the thing, as I said, is in no state at all, and that is an absurd supposition, an absolute inconceivability. Such is the perplexity in which we are landed if we hold asunder Being and not-Being, and fix them as two separate conceptions. Indeed, so sensible were the Eleatics of the force of such reasonings as that which I have placed before you, that, instead of attempting to explain change, they boldly denied its possibility. They saw that it could not be explained on their principles, and therefore they maintained that all change was mere illusion; that, in fact, there was properly no such thing, and that the universe, according to reason, and in its truth, was immutable and uniform. I have stated that the Eleatics constituted Being and not-Being into two separate conceptions, and that the difficulties which beset their philosophy had their origin in this separation. This statement I142 GREEK PHILOSOPHY. conceive to be quite correct, although you ought to bear in mind, as some slight qualification of it, that the Eleatics, after having made the separation referred to, put away from them as unworthy of all consideration the conception of not-Being, and con- fined themselves exclusively to the conception of Being. They discarded not-Being as an overt prin- ciple of their philosophy. But from their having fixed Being as a conception by itself, which excluded not-Being, we may fairly infer that they fixed not- Being as a conception by itself, which excluded Being. But however this may be, it is certain that change cannot be explained, cannot even be admit- ted, on the principles of their philosophy. 34. It is otherwise in the system of Heraclitus. He begins, not with Being or the fixed, but with Becoming or the fluctuating. According to him, the principle, the beginning, the starting-point of all things is change, and therefore he is not under the necessity of explaining it, that is to say, of deducing it from anything anterior. He does explain it, or at least he throws out certain dark and brief words, by pondering over which we are at length able to explain it for ourselves. What, then, do we understand to be Heraclitus's conception of change or Becoming, a conception by means of which he avoids the per- plexities in which the Eleatic thinkers got involved ? His conception is, that Becoming is a unity which involves the two moments of Being and not-Being.HERACLITUS. 143 I have already illustrated this unity at considerable length, I must now therefore deal with it very shortly. Stated abstractly, the conception is this: According to Heraclitus, a state of being is itself a state of not- being, that is, it is even in being gone as soon as come; which state of not-Being is itself another state of Being, which other state of Being is itself a state of not-Being, which state of not-Being is itself another state of Being; and so on. Viewed in this way, we must say of the universe, that at every instant it both is and is not; it is, there can be no doubt about that; but then the changes in the universe are so continuous that it also is not; that is to say, it is not this definite universe which we conceived we had laid hold of, but another; which other again is not— is not this definite universe, but another; and so on. We can never catch it. Take our former illustration. A thing is in the state A; how is it to come out of that state and get into the state B ? We saw that on Eleatic principles that problem admitted of no solution. What is Heraclitus's answer? Heracli- tus's answer is, that the thing is already out of the state A; that in the very act of being in that state it is out of it. The two moments, the moment of being in it and the moment of being out of it, are one, and constitute one indivisible conception, the conception of Becoming; and then, just as the being in the state and the being out of it are one, so the being out of it and being in another state, the state B, is one; and so on the process goes. It is infin-144 GKEEK PHILOSOPHY. itely too fine for sense to approach the apprehension of. The changes manifest to the senses might more properly be called catastrophes than changes. Thus, when I place a piece of wax before the fire and it melts, what I perceive is a change from opaque solidity to transparent fluidity. But fluidity is the catastrophe; it is the precipitated result of an accumulated series of changes in the wax, wThich are no less than infinite. Each of these changes—or call them states, for at each change the wax was in a particular state—each of these states no sooner is than it is not. In appearing it disappears ; but the disappearance is the appearance of a new state. The whole process is a series of vanishing fluxions, each of which in being ceases to be. But I have already illustrated this matter in so many ways that I must now desist. "What you have to bear in mind as the gist of the Heraclitean solution of the problem of change is this, that the Being of every state in which a thing is, is the not-Being of that state; and that the not- Being of that state is the Being of another state; for that is what is meant by the unity of Being and not-Being, and by these two being elements of one conception, and not each of them a separate concep- tion by itself. Viewed abstractly, the unity of these two contraries, Being and not-Being, may appear a paradox and an absurdity, but from the explanations and illustrations I have given you, perhaps you may /be inclined to accept the doctrine as intelligible, if not as convincing. If you accept the doctrine asHERACLITUS. 145 intelligible, you will perceive that it carries with it a solution of the problem of change. How does a thing ever get out of one state into another ? Be- cause, says Heraclitus, in being in the state in which it is, it is already out of it. Being in it, is being out of it; and being out of it is being in another state. The two are identical; and therefore I am not called upon to explain any further how the process is brought about. The process, indeed, is its own explanation. 35. Although the utterances of Heraclitus are ex- ceedingly obscure and fragmentary, so fragmentary, indeed, as scarcely to be entitled to the name of remains, and although it is difficult or impossible to bring out the points with all the clearness and co- gency that might be desired, I am nevertheless con- vinced that some great truth lies here: that here, if anywhere, is the embryo of the solution of the enigma of the universe. I am convinced that the unity of contraries is the law of all things; that all life, all nature, all thought, all reason, centres in the oneness or conciliation of Being and not-Being. A firm grasp of this doctrine, a clear insight into its truth, and a vigorous enforcement of it and of its. consequences, would lead to the construction of a truer philosophy than that which is at present so much in vogue. That philosophy is founded entirely on the denial of the unity of contrary determinations in the same subject. It takes two opposite conceptions, and hold- K146 GREEK PHILOSOPHY. ing them apart it shows that reason is baffled in its attempts adequately to conceive either of them. It is in this way that Sir W. Hamilton and Mr Mansel achieved what they conceive to be a great triumph in proclaiming, or, as they think, in proving the im- potency of human reason. But what if the concep- tions thus set in opposition to each other are not conceptions at all, but are mere moments or elements of conception ? If they are so—and I believe that they are so—that would make a great difference. The antagonism would no longer exist, or, if it existed, it would be a very different kind of antagonism from, that for which Hamilton and Mansel contend. It would be an antagonism building up one indivisible conception, and, therefore, an antagonism essential to the very life and essence of reason itself, and not an antagonism by which reason is placed at variance with itself, and thus confounded, disabled, and paralysed. EMPEDOCLES. 1. The next inquirer with whom we have to deal in our survey of the history of ancient philosophy is Empedocles of Agrigentum. The philosophical remains of Empedocles con- • sist of some fragments of a poem TJepl (frvaecos, or con- cerning nature; for, like Xenophanes and Parmenides, he recorded his opinions in verse. This didactic poem is rather physical and physiological than phil-EMPEDOCLES. 147 osophical, and we can extract from it but little that i£ of speculative interest and value. It contains, how- ever, some forcible expressions, and was highly esteemed by Lucretius, who, in his own poem, ' De Eerum Natura,' seems to have adopted it to some extent as his model, and who speaks of it and of its author in the following terms, which we cannot but regard as somewhat exaggerated in their eulogy: " Carmina quin etiam divini pectoris ejus Vociferantur, et exponunt prseclara reperta, Ut vix humane videatur stirpe creatus." —Ltjcret., I. 731-733. The fragments of this poem of Empedocles were col- lected about twenty years ago, and published, along with those of Xenophanes and Parmenides, by Kar- sten, a Dutch scholar, to whom I formerly referred. 2. The three features in the philosophy, or rather in the physics, of Empedocles by which it is best known are: First, His enunciation of a distinction which, although of no great scientific value, has kept its place in the popular mind even to the present day. I refer to his division of the constituents of the universe into the four elements, fire, air, earth, and water. Empedocles is said to have been the first who enumerated these four as the roots, pi^co/juara, of all things. Secondly, All things, he held, were formed out of these four elements by a process of mingling and of separation. This mingling was a mere mechanical aggregation or agglutination of the different elements,148 GREEK PHILOSOPHY. so that all objects were, in themselves, fire, air, earth, and water, whatever might be the appearance which they presented to us. And, Thirdly, This process of mingling and separating was set in motion and governed by two principles, fyikla and velrcos; friendship or love; and velKos, enmity or hate. 3. After all my study of Empedocles and his ex- positors, I am unable to find in him anything better than a confused scheme of crude and fanciful physics. I shall therefore dismiss him, after having directed your attention to a certain dogma which has occupied an important place in the history of philosophy, and which, although current before the time of Empe- docles, was first laid down by him in distinct and emphatic terms. The dogma to which I refer is the saying that like can be known only by like. " Simi- lia similibus cognoscuntur; " that is to say, the thing which knows must be of a nature cognate or analo- gous to that which knows it; or, as Empedocles ex- presses it, "We perceive earth by means of earth (the earth, that is, of which we ourselves are made), we perceive water by means of water, and air by means of air, fire by means of fire, love by means of love, and strife by means of strife;" that is, it is by means of the earth, the water, the air, the fire, the love, and the strife of which our own nature is composed, that we are able to apprehend the earth, the water, the air, the fire, the love, and the strife that are exter- nal to us. A crude enough doctrine, as thus stated,EMPEDOCLES. 149 and yet one which may not be altogether devoid of truth, and which, at any rate, may furnish food [for meditation. 4. But my principal reason for alluding to this dogma is on account of the prominent place which has been assigned to it by Sir W. Hamilton in the history of philosophy. From this maxim, " Similia similibus cognoscuntur," he derives the theory of a representative perception; that theory which it was the business of Dr Eeid's life to overturn. The theory was, that the mind had no immediate cogni- sance- of external objects, no cognisance of objects themselves, but only of certain vicarious images or representations of them. On what ground does this opinion rest ? It rests, says Sir William, on the dogma that like can be known only by like. Eeal things being unlike the mind—the mind being spirit- ual, while they are material—they cannot be known by the mind; they cannot be its direct or immediate objects, but their images, being incorporeal—in other words, being of a nature analogous or like to the mind—can be known, and are alone known, by the mind in the intercourse which it holds with external things. Deny this dogma, then, affirm its opposite, that the mind can know what is altogether unlike itself, and of a different nature from itself, and you cut away the ground on which the doctrine of a representative perception rests. Such is the purport of Sir W. Hamilton's statement. You will find the150 GREEK PHILOSOPHY. point handled in his 'Discussions on Philosophy,' p. 61, 2d edition. 5. The philosophy of Empedocles is, for the most part, rather physical than speculative. This prepon- derance of physics is indeed the general character of the pre-Socratic systems. Their metaphysical import is rather implied than expressed; and what appears on their surface is generally a mere farrago of crude and fanciful, and often unintelligible, descriptions and explanations of the phenomena of the natural world. Of such materials the poem of Empedocles, Uepl v) ? The exposition of what man is by nature would constitute the psychology of the Sophists: the exposition of what he is by convention would constitute their ethics. But it is not difficult to see that, arising out of their psychology and immediately connected with it, there would be what we may call a code of natural ethics, as distinguished from that code of conventional or social or artificial ethics to which the name of ethics is more properly applied. Indeed this word ethics is properly applied to man only when in society; still it may be allowable to apply it to man in a pure state of nature when we explain it as meaning those natural commands which prompt and impel every sentient creature to gratify its wants. 20. Before touching on any of these points, either on the psychology or the ethics of the Sophists, let me call your attention to an important consideration which throws, I think, much light on their mode of inquiry. The consideration is this, that whatever can be shown to be imposed upon man by Nature, must be more binding and authoritative than that which is imposed upon him merely by society. Nature's commands must be obeyed first, because Nature is primary and fundamental; society's com- mands must be obeyed only in the second instance,THE SOPHISTS. 199 because society is less real, less cogent than Nature; and where the two commands are at variance, where Nature pulls one way and social morality another way, Nature must be yielded to, because nature is weightier, and in every way more venerable, than con- vention. That doctrine, you will observe (and it is a doctrine which carries with it a good deal of plausi- bility), opens a door to the inroads of every species of licentiousness. I do not believe that the Sophists themselves ever opened that door very wide; but they indicated its existence, and some of them cer- tainly left it ajar, to the perplexity and alarm of all right-minded citizens. This consideration may serve to show that the estimate usually formed as to the dangerous and pernicious tendency of the Sophistical speculators, although exaggerated, is not altogether wrong. This remark is somewhat digressive. I return to the psychology of the Sophists, on which I shall say a very few words. 21. This prime question of moral philosophy, as I have called it, is no easy one to answer, for it is no easy matter to effect the discrimination out of which the answer must proceed. It is a question, perhaps, to which no complete, but only an approximate, answer can be returned. One common mistake is to ascribe more to the natural man than properly be- longs to him, to ascribe to him attributes and endow- ments which belong only to the social and artificial man. Some writers—Hutcheson, for example, and he200 ' GREEK PHILOSOPHY. is followed by many others—are of opinion that man naturally has a conscience or moral sense which dis- criminates between right and wrong, just as he has naturally a sense of taste, wThich distinguishes between sweet and bitter, and a sense of sight, which discrimi- nates between red and blue, or a sentient organism, which distinguishes between pleasure and pain. That man has by nature, and from the first, the possibility of attaining to a conscience is not to be denied. That he has within him by birthright something out of which conscience is developed, I firmly believe; and what this is I shall endeavour by-and-by to show, when I come to speak of Socrates and his philosophy as opposed to the doctrines of the Sophists. But that the man is furnished by nature with a conscience ready-made, just as he is furnished with a ready- made sensational apparatus, this is a doctrine in which I have no faith, and which I regard as alto- gether erroneous. It arises out of the disposition to attribute more to the natural man than properly be- longs to him. The other error into which inquirers are apt to fall in making a discrimination between what man is by nature, and what he is by convention, is the opposite of the one just mentioned. They sometimes attribute to the natural man less than pro- perly belongs to him. And this, I think, was the error into which the Sophists were betrayed. They fell into it inadvertently, and not with any design of embracing or promulgating erroneous opinions. We shall see by-and-by how Socrates availed himselfTHE SOPHISTS. 201 of this error in the psychology of the Sophists, and how he corrected it. 22. In answer to the question, What, and what alone, appertains to man by nature ? the Sophists replied in one word, sensation. It is certain that man has by nature certain senses, and that he is naturally sensitive to pleasure and to pain. He has also, as part of his constitution, certain appetites, passions, and desires. Some of these, however, exist only in society, and are probably created only by our contact with society. The other appetites and passions which man brings with him into the world are so in- timately connected with organic pleasure or pain that they may be placed under the head of sensation, and thus sensation, or a susceptibility and experience of pleasure or of pain, is properly all that belongs to man by nature. That this attribute is natural to him is what cannot be for a moment doubted. He comes into the world feeling, that is, alive to enjoy- ment or suffering, at every pore. In regard to all his other attributes, we cannot be sure that they are not entirely due to the influences and operation of society. 23. To what extent the Sophists admitted thought to be an indigenous property of man seems somewhat uncertain. It is probable that they did not admit it as anything different from sensation. They either slurred it over without much notice, or they regard- ed it as the natural sequent or accompaniment of202 GREEK PHILOSOPHY. sensation, and as itself resolvable into sensation. This latter attribute, together with certain appe- tites and desires, these alone, in the psychology of the Sophists, were the original furnishings of human nature. Sensation was the foundation on which the whole superstructure of humanity and of society rested. The Sophists were thus the first in- quirers who distinctly propounded a philosophy of pure sensationalism, that is to say, a doctrine which refers all the phenomena of thought, and all the operations of the mind, to sensation as their ultimate source and origin. This doctrine has had many advocates, both in ancient and in modern times. The English philosopher, Locke, lent it his countenance, although not without some reservations. The French philosophers of the eighteenth century put aside these reservations, and proclaimed a doctrine of sen- sationalism without any qualification; but the first who propounded the doctrine were the Sophists. Their psychology began and ended in sensationalism. 24. In a state of nature, then, and apart from society and all its relations, man, according to the Sophists, is a mere creature of sensation, includ- ing under that term certain appetites and de- sires, and the experience of pleasure and of pain. This is what man is in himself; he is, as he comes from the workshop of nature, a mere series or com- plement or congeries of sensations. That, say the Sophists, is what man, the individual or isolatedTHE SOPHISTS. 203 man, is, as distinguished from the social or gre- garious man. Out of this psychology a system of what we may call natural ethics would evolve itself. To a creature made up of sensations the law of self- preservation and of self-enjoyment must be the most authoritative of all commands. Such a being must necessarily pursue its own gratification; for pleasure is sweet and attractive, pain is hateful and repulsive, to all the organised creation. Hence, whatever con- fers pleasure on the individual will be passionately run after and approved of, whatever inflicts pain will be anxiously shunned and condemned. "Nature," says Jeremy Bentham, "has placed mankind under the governance of two sovereign masters, pleasure and pain. It is for them alone to point out what we ought to do, as well as to determine what we shall do." Whether, and in what sense, pleasure and pain may be said to be the two sovereign masters of man- kind in a state of society, I shall not at present stop to inquire: but it is certain that they must be the only two governing principles of man, viewed as a mere sensational being, and considered as he is in himself and out of all relation to his fellows. His ethics, in such a case, could scarcely be called self- ish, for selfishness implies not only an exclusive regard to one's self, but a disregard to the claims of others. But there are no others at present in the case, and therefore their claims cannot be disre- garded ; but in so far as an exclusive regard to one's self is concerned, the natural ethics which arise out204 GREEK PHILOSOPHY. of the psychology of the Sophists must be pro- nounced to be virtually of a purely selfish character. The same law of nature which makes a man suscep- tible of pleasure and of pain, giving no other guides, imposes on him the duty of securing the one and of avoiding the other to the utmost degree in which they can be secured and avoided. 25. Thus furnished by nature, man is turned adrift into the world. He comes upon the scene equipped with sensations which constitute his very existence, and with a natural code of ethics which oblige him to preserve himself and to enjoy himself as much as he possibly can. Thus the isolated man, man as he comes from nature, man with his indi- vidual interests, is the measure of the universe to himself. Whatever his sensations bring home to him as true and real is true and real for him, what- ever it may be in itself. His sensations are for him true and real, although all beyond should be illusion or nonentity, and these sensations are for him the universe. Then again, whatever promotes agreeable sensations is right for him, whatever it may be in itself; whatever promotes disagreeable sensations is wrong for him, whatever it may be in itself Thus man is, as the Sophists say, the measure of the uni- verse. His individual nature measures and deter- mines its reality. His individual nature measures and determines what in the universe is right and what in the universe is wrong.THE SOPHISTS. 205 26. But although man comes into the world thus naturally equipped, he finds there much that is at variance with these natural provisions. He finds established in society a code of morality which is by no means in accordance with what we have called the ethics of nature. By the ethics of nature man is bound to regard his own interests as paramount, and to look after these alone; by the ethics of society he is called upon to respect the interests of others, as well as to abridge or sacrifice his own pleasures, and to lay a restraint on his self-indulgent appetites. These new regulations square but badly with the injunctions laid upon him by nature. And the pur- port of the Sophistical teaching was, I conceive, to point out the inconsistency, without offering any adequate solution. Their object was to stir up in- quiry, and as a preliminary to this, it was necessary to induce perplexity of mind. Doubts and difficul- ties must present themselves before any clearness of thought can be attained. These doubts and diffi- culties and contradictions were evolved by the ar- gumentative exercitations of the Sophists; and I conceive that their exhibition was absolutely essen- tial to the progress of philosophy, and as a step to something better. Let us honour and not disparage the Sophists for having been at the pains to throw these embarrassments (what the Greeks called anrplai) in the way of thinking men. They argued that the morals of nature were opposed in much to the mo- rals of convention, that the morals of nature were206 GREEK PHILOSOPHY. supremely authoritative, inasmuch as they were grounded on nature herself. Nature herself is here the ground of our obligation, and under her behests we are bound to pursue to the utmost our own plea- sure and avoid our own pain. But on what are the morals of society grounded ? On something much less authoritative, on mere convention or arbitrary agreement among men. But these conventional rules are, or at least appear to be, less obligatory than the injunctions laid upon us by our own appe- tites, passions, and desires. Why, then, should they be obeyed ? what, in short, is the ground of the moral obligation imposed upon us by society ? The ground on which man's obligation as an individual rests is, as I have said, obvious enough; it rests upon nature herself. But man's obligations as a citizen do not rest on nature, for they stand opposed to much which nature dictates. On what, then, do they rest ? what is the ground of social moral obli- gation? For the raising of this question we are mainly indebted to the Sophists, to the spirit, if not to the letter, of their inquiries; and the question seems to have been brought to light in some such manner as I have described, namely, by playing off the natural or isolated man against the social and artificial man—the individual, taken simply and as he is in himself, against the individual taken socially, and as he is in company with his fellow-men. 27. I have said that the Sophists furnished noTHE SOPHISTS. 207 adequate solution to the question as to the grounds of the moral obligation which society imposes on its members, nor did they profess to furnish any, their object being rather to induce perplexity and provoke discussion. But some solution they certainly did attempt, and some of their views were not unlike those propounded by the Utilitarians of the present day. I shall merely touch upon these answers. Some of the Sophists contended that might was the ground of moral obligation; that the strong, who were able to enforce conformity, determined what was right, determined this either by positive enact- ments or by the force of public opinion, and that hence the weaker were constrained to obedience through fear. Another party, according to Plato, contended that although injustice was right by na- ture, inasmuch as nature prompted a man to grasp at everything he could reach without giving heed to the claims of others, still it was wrong by conven- tion, for this reason, that the man who committed injustice would be sure at one time or other to suffer from injustice; and therefore, in order to avoid this suffering, which to him would be wrong and grievous, he would refrain from committing in- justice, however right and agreeable he may think it. According to this doctrine, it is good for each man to commit acts of injustice on others, it is bad to have acts of injustice committed on one's self; and hence, as it is impossible to avoid the latter without also giving up the former, men agree to abstain from208 GREEK PHILOSOPHY. acts of injustice, doing so, not because they conceive injustice to be bad when they actively inflict it, but because they conceive it to be bad when they pas- sively endure it. The pain which they feel when they suffer from injustice outweighs, for the most part, the pleasure which they feel when they commit it; and hence injustice comes to be stamped with general reprobation, and its opposite with general ap- plause. Such an explanation represents self-interest in its most undisguised form as the ground of moral obligation. Others, again, would argue that the ad- vantage and wellbeing of the community, of which each man was a member, was promoted by the ob- servance of these moral rules; and hence the promo- tion of this welfare was a sufficient reason why these rules should be observed. The promotion and main- tenance of the wellbeing of society was thus set forth as the ground of moral obligation. This is no other than the modern doctrine of Utilitarianism. 28. These solutions,-however, were felt to be in- adequate and unsatisfactory. It was felt, in partic- ular, that no true conciliation was effected by such explanations between what we have called the nat- ural ethics of the individual and the conventional ethics of the citizen. The question still remained unanswered, Why, when a man could commit injus- tice with the certainty of impunity both in the pres- ent and in the future, he should not commit it ? On what ground, and for what reason, it might still beTHE SOPHISTS. 209 asked, should he, in such circumstances, not commit injustice ? No Sophistical theory was able to answer that question; or if they answered it at all, their answer was, that a man in the position indicated should just follow the bent of his natural inclinations and commit injustice, doing what seemed to him good in his own eyes, and not what was reckoned good in the estimation of society. The commands of nature carry more authority than the laws and regulations of society; therefore, when they can be obeyed with impunity, they ought to be, and they will be, obeyed. Such was the spirit and tendency of much of the Sophistical mode of argumentation. 0SOCKATES. 1. There were two ways in which the perplexities occasioned by the argumentations of the Sophists might be encountered and rebutted. The one way was by abjuring all inquiry, and by falling back, in blind faith, on the old traditional morality as a matter too sacred to be questioned or investigated. This was the course adopted by the orthodox or civic or conservative party in Athens, the party of whom Aristophanes may be taken as the mouthpiece and representative. Looking merely to the mischief which the agitation of the Sophists tended to pro- duce, and had perhaps actually produced, they be- came clamorous in their denunciations of these new pretenders to wisdom. They set their faces against the freedom of thought and of inquiry which these innovators had inaugurated. Their subtlety they regarded as empty quibbling—as a quibbling, how- ever, which was dangerous to the institutions and the interests of society; and their reasonings, they held, should be put down rather by persecution than by argument. That was their idea of the way inSOCRATES. 211 which the Sophists should be dealt with. This party took its stand on the ancient beliefs, it clung to the social order and to the prescriptive morals which it had inherited from time immemorial, as a divinely appointed system. It reverenced them all the more on account of the obscurity in which their origin was shrouded; and it threatened vengeance against all who, by intellectual sophistications, would in- fringe or imperil institutions so venerable and so benign. 2. The other way of dealing with the Sophists was that which Socrates followed out. Unlike the orthodox party, he was far from being at variance with the Sophists in regard to the fundamental posi- tion which they had taken up; on the contrary, he cordially agreed with them as to the,propriety, indeed the necessity, of subjecting the institutions of society and everything in which man was interested, or about which man could speculate, to the ordeal of a rigorous examination. No Sophist was ever more keenly bent on free and searching inquiry than he: and this is the reason why he has frequently, and not erroneously, been identified to a large extent with that party. If Socrates had been compelled to make his option between the Sophists and the old stub- born citizen party at Athens, there is little doubt which side he would have chosen. He would have thrown in his lot with the Sophists; for this party was at any rate awake and flexible with intellectual212 GREEK PHILOSOPHY. life and movement, whereas the other party was stiff and stolid, was sunk in a dogmatic slumber, was stationary if not retrograde. But Socrates was not compelled to choose between these two parties; another course was open to him, and on that other course he entered. He agreed with the Sophists in calling for free inquiry; but he demanded, further, that that inquiry should be thoroughgoing and com- plete, more thoroughgoing and complete than it had been under the management of the Sophists. This, then, was the preliminary ground on which Socrates opposed the Sophists; their inquiry into the nature of man he held had been partial, inadequate, and superficial; his professed to be more radical, more searching, and more comprehensive. 3. We have now to consider in what respect Socrates deemed the inquiry of the Sophists to be partial and incomplete, and how he endeavoured to supplement it; but, first of all, let me apprise you, that in attempting to work out the philosophy of Socrates, I shall be compelled, in the absence of full and accurate historical data, to draw considerably on my own reflections for materials, and to fill in de- tails which, though implied and hinted at, are not explicitly presented in any of the remains which are extant of the Socratic doctrines. In attempting to give a consistent and intelligible account of the Socratic system, both as it is in itself and as it stands opposed to the doctrines of the Sophists, ISOCRATES. 213 shall be obliged to attribute to him opinions which even Plato does not articulately vouch for as belong- ing to Socrates. I shall be under the necessity of showing that he virtually, although obscurely, raised and resolved questions which were not expressly or definitely propounded until after his time. This, therefore, has to be kept in view, that although all that I shall attribute to Socrates has, I conceive, a sufficient warrant in the general scope and spirit of his philosophy, there will be some things in my exposition for which no exact historical authority can be adduced. This course will, at any rate, con- duce to intelligibility; and it is better, I conceive, to be intelligible by overstepping somewhat the literal historical record, than to be unintelligible, as we must be, if we confine ourselves slavishly within it. It is bad to violate the truth of history, but the truth of history is not violated, it is rather cleared up, when we evolve out of the opinions of an ancient philosopher, more than the philosopher himself was conscious of these opinions containing. Such an evolution I propose to attempt in dealing with the philosophy of Socrates. 4. We have already seen that the psychology of the Sophists represented the natural man as cen- tring entirely in sensation. Sensation, with its pleasures and its pains, was so prominent and im- portunate, the knowledge which it imparted, or ap- peared to impart, was so various and so assured—214 GREEK PHILOSOPHY. assured at least in so far as the individual affected by the sensations was concerned—that it threw all the other mental phenomena completely into the shade. The Sophists indeed held, as I have said, that there were no other mental phenomena, no phenomena which were not resolvable into one form or other of sensation, no phenomena which had not their origin in this all - comprehensive endowment. But the question may be raised, Is sensation thus exclusive and all-comprehensive ? Is it the all in all of human nature ? Is it the one and only endowment of man, viewed even in his most elementary condition as an isolated and unsocial individual ? That was pre- cisely the question which Socrates raised, and he answered it in the negative. Man is not a mere series of sensations. Even in his most primitive state, and as he comes from the hands of nature, there are elements within him entirely different from sensation. This position was equivalent to declaring, that the analysis or inquiry of the Sophists had been partial and incomplete. And such, I said, was the position taken up by Socrates at the outset. 5. I remarked on a former occasion, that thought or thinking was a phenomenon, was rather the phe- nomenon, which the Sophists had neglected to take into account. In prosecuting their inquiries they had, of course, made use of thought, for they could not have conducted their researches or their arguments without it; but they had employed it merely as theSOCRATES. 215 instrument, and not as the object of their researches. They did not turn a reflective eye upon the instru- ment or medium through which their observations were made. Just as the astronomer does not look at his telescope, but looks through it at the stars, so the Sophists overlooked thought itself, and at- tended merely to what was revealed to them through its means. But, in consequence of this oversight, their analysis was exceedingly defective; because, while it is quite proper that the astronomer should overlook his instrument, the telescope, inasmuch as some star, or whatever the object may be, is all that he is professing to examine, it is by no means pro- per that thought, the instrument of the philosopher, should be overlooked in the same way. Thought is not only the philosopher's instrument, it is also the object or part of the object which the philosopher is called upon to investigate and explain. He pro- fesses to examine human nature; if, therefore, he merely employs thought in the examination without making it part of the thing examined, he is not faith- ful to his calling, he is leaving out of the survey an element which the survey ought to embrace; his observations, accordingly, will be imperfect, and his report false and incomplete. This was what befell the investigations of the Sophists. Their report of human nature was defective, because it left out of account the element of thought, an element which, no less than sensation, although in a much less obtrusive degree than sensation, is a characteristic216 GREEK PHILOSOPHY. endowment even of the natural man. Thought was the element which Socrates found fault with the Sophists for having overlooked. 6. Here, perhaps, an objection might be raised. It might be said that thought has no place in the econ- omy of the purely natural man, but that it owes its being entirely to the action and the influences of so- ciety. It might be argued, in the language of modern schools, that thought is a secondary and derivative, not a primary and original formation. It is not im- probable that this was what the Sophists actually maintained. I said formerly that they either ignored thought, or merged this phenomenon in the pheno- mena of sensation. Perhaps this assertion should be qualified by the statement that there was still another way in which some of them disposed of the phenome- non of thought, another point of view under which they regarded it, and that was, its conventional character and origin. They may have held that thought was due to the social circumstances in the midst of which man was placed, no less than the rules of morality were due to these same circumstances. And if this were the case, if this could be made out, it would leave sensation as the sole fundamental constituent of human nature; in which case, the contradiction be- tween nature and convention, the opposition between what man was in himself and what he was through his contact with society, the discord or antagonism between the natural ethics of sensation and desireSOCKATES. 217 and the artificial ethics of social life, would remain unreconciled. In short, all the perplexities and doubts and difficulties called forth and set in motion by the speculations of the Sophists would continue uncounteracted, and would subsist in full activity and force. As part, therefore, of the Socratic dialec- tic, it was quite indispensable to show that thought was an indigenous endowment, a quality of human nature no less than sensation, appetite, and desire. This proof, accordingly, was the main part of the business which Socrates was called upon to perform. He had to prove that thought was man's by nature, and that it was entirely different from sensation, and its accompaniments, passion and desire. Here I shall have to introduce, as I said, some links of specula- tion which are not to be found in any extant record of the Socratic doctrines; but I believe that I shall deviate in no respect from the spirit of the Socratic procedure, and that I shall advance nothing which has not a basis and warrant in the principles of the philosopher himself. 7. To determine whether thought is natural or acquired, is primary or derivative, we must of course ascertain first of all what thought is, what it is in itself, and as distinguished from everything else. This can only be effected by self-reflection, by rigorous self-examination. Hence the maxim which Socrates assumed as the very watchword of his sys- tem, as the very condition on which alone any phil-218 GREEK PHILOSOPHY. osophy is possible, yva)0c aeavrov, know thyself. That is very easily said, and to some extent, and in a superficial way, it is perhaps very easily done. But to do it really and effectually, to know ourselves truly, to get to the bottom of what we are as thinking beings; to know what thought is in itself, and as dis- tinguished from sensation, to perceive that it is our very essence, and to make others perceive this also; this is indeed no easy matter, but, on the contrary, the hardest task in which a philosopher can be en- gaged. This precept, S>6i aeavrov, otherwise all that I am saying will go for nothing. There is one thing, however, which I must impress upon youSOCRATES. 239 by way of caution; you must not expect to be able to verify the fact of sensation and the fact of thought apart from each other; you must not expect to be able to study the phenomenon of sensation by itself and prescinded from all thought. That is impos- sible : because, in the very act of studying the sensa- tion, you must think it; so that it is impossible to lay hold of it by itself. The two-cannot be separated in such a way as may enable you to report upon sensation without taking thought into account as well. But still, although the two must be taken together, this need not prevent us from obtaining a distinct conception of each, or from perceiving that the one element is quite different from the other, that each is, indeed, the opposite of the other. 22. Having thus put you on your guard against encouraging an expectation which cannot possibly be fulfilled, I go on to stimulate your own reflections with the view of assisting you to reach a still clearer understanding of the distinction between thought and sensation, the bondage of the latter and the liberty of the former. Let us consider the contrast between the two. When a man feels a sensation (say the scratch of a pin), the sensation never dis- engages itself from itself in such a way as to make the man feel other sensations. The feeling of a sen- sation is never the feeling of that sensation and of other sensations besides; it is the feeling of that sensation only. Hence sensation, each sensation, is240 GREEK PHILOSOPHY. bond, not free; each of them has no range beyond itself. It is quite otherwise with the thought of a sensation. The thought of a sensation is not limited to that sensation. I mean that the very first time, and in the veiy first instant, in which a sensation is thought, the thought is not limited to that sensa- tion ; if it were limited to it, it would be mere sen- sation, not thought. It takes in something more, it has a range, it extends to other sensations as well. Thought thus disengages itself from the particular sensation, it puts a negative upon it, it in a manner denies that the sensation is it, the thought; it starts away from the sensation, and brings down upon it a universal, a conception which embraces other pos- sible sensations as well. Instead of saying that thought disengages itself from the particular sensa- tion, it would be more correct to say that this disen- gagement is itself thought. There is not, first of all, the thought of the sensation and then the disen- gagement of the thought from the sensation, and its extension to other instances of the same. No; the process is better described by saying that the disen- gagement, the disenthralment from the sensation, is itself the thought of the sensation. The two are identical. The thought does not precede the disen- gagement, nor does the disengagement precede the thought: but the thought is the disengagement and the disengagement is the thought. So that we may say of thought that it is a mental disengagement from every particular sensation, a mental refusal to beSOCItATES. 241 limited to any particular sensation, and a liberation from the same; while we may say of this mental disengagement, refusal, and liberation, that it is no other than thought. On the other hand, sensation is no disengagement from a particular sensation, no mental refusal to be limited to a particular sensa- tion ; it is no liberation from a particular sensation, but is, on the contrary, an absolute acquiescence in the limitation and thraldom by which each sen- sation is characterised. 23. After what I have just said, you should have no difficulty in perceiving that thought must be active as well as free. These two words, indeed, signify the same thing. If the freedom of thought consist in its disengaging itself from the particularity of sensation, it must, of course, be active in effecting this disengagement. This disengagement is mani- festly an act, and in putting forth this act the mind is in a condition quite different from its passive state when recipient of sensation. But I need not dwell on this point. I may just remark that you should now be able to attach some meaning to the words free and active when applied to thought — a more distinct meaning, perhaps, than you have been ac- customed to apply to them when used in that con- nection. 24. We have now reached the conclusion at which we have been aiming, and which must be made out Q242 GREEK PHILOSOPHY. if we would plead with effect the cause which Socra- tes advocated against the Sophists. That conclusion is, that thought is not only quite distinct from sen- sation, but that, in virtue of its freedom and self- origination, it is, moreover, a primary and indigen- ous product of the mind. The Sophists held that sensation, appetite, and desire, that these alone, were our primary attributes, were the only indefeasible principles of our nature. But we have seen that thought is more original and primary, if I may say so, is ours by a more indefeasible title, than sensa- tion, appetite, or desire. Thought, in fact, is ourself, our essential self, inasmuch as it is originated by the free activity of the mind. The other endowments referred to are the mere accidents or accompaniments of ourself. Thus the tables are turned upon the Sophists. So far is it from being true that man is originally by nature a mere sensational creature, that it would be more correct to say that man in his true nature is a mere thinking creature. Thought, and not sensation, is his peculiar characteristic. Thought is his essential property. It is that which makes him what he is. It constitutes his being more truly than sensation, appetite, and desire. For these are necessi- tated, are forced upon him from without. But thought is free and active. It is originated by the mind it- self from within, and therefore belongs to it more closely and essentially than any other endowment. 25. I have not yet spoken directly of self-con-SOCRATES. 243 sciousness, but in the foregoing remarks I have given you what I conceive is the true speculative history of the rise and manifestation of that mental act. To complete my explanation of self-consciousness I have still a few observations to make, and then we shall proceed to consider what bearings the conclusions we have established have on the doctrines of the Sophists. Man alone is characterised by self-consciousness. This endowment certainly does not belong, and is not to be attributed to, the lower animals. They have feeling, sensation, appetite, passion, desire; but they certainly have no thought or consciousness of them- selves, no self-consciousness, in the proper sense of that word. There is, however, an improper sense in which every sentient creature, as well as men, may be said to be self-conscious. What is that sense ? By pointing out that sense we shall be better able to apprehend and explain what true self-consciousness is. When a sentient being experiences a sensation, it may be said to feel itself \ as well as the sensation. (Observe, I do not say that it thinks itself; that is a very different matter.) But it feels itself as that which is experiencing the sensation. It shuns or endeavours to get rid of painful sensations: it courts and endeavours to procure pleasurable ones. When a cat lies by the fire or in the sun, it enjoys an agree- able warmth. We cannot doubt that it feels itself doing so. When a dog is hungry, or has got his foot hurt, we cannot doubt that he feels himself in a painful predicament. But in neither of these cases,244 GKEEK PHILOSOPHY. nor in any cases of a like kind, is any approach made to the thought of themselves by these animals. They have the feeling of themselves, but no con- ception of themselves. And if we choose to call this feeling of themselves by the name of self-conscious- ness, we may attribute to them self-consciousness; but if by self-consciousness we mean having a con- ception of themselves, we must deny that animals have any self-consciousness, for we cannot allow that they have any conception of themselves. I think that the term ought to be used in this latter accepta- tion only, and that although we may speak of ani- mals having a feeling of themselves, we should never say that they have self-consciousness or a conception of themselves. 26. But perhaps you may imagine that there is no very great difference between the feeling of oneself and of one's own pains and pleasures, on the one hand, and self-consciousness, or the thought of one- self and of one's own pains and pleasures, on the other hand. The following remarks, then, may help to convince you that the difference, both in itself and in its consequences, is momentous and extreme. When an animal feels itself and its own sensations, it does not, and it cannot, feel another animal and another animal's sensations. For example, when a dog feels itself hungry or suffering from a sore foot, it does not feel the hunger of another dog or the pain in another dog's foot. It feels only its own hungerSOCKATES. 245 and its own pain. It can feel only itself and its own sensations, whatever these may be, and no augmen- tation of these will enable it to go beyond itself: indeed, we might say the more it feels its own sen- sations, the more these are intensified, the more these occupy it, the less does it feel the sensations of any other animal. Hence animals have no sympathy for each other. This. want of sympathy is a necessary consequence of their being tied down to the feeling of themselves and of their own sensations. Under this limitation it is impossible for them to take others into account, and the pains and pleasures which others may be experiencing. For, as I have said, one sentient being can never feel the sensations of another sentient being; and therefore, if it be limited, as animals are, to mere feeling, it must be utterly indifferent to others and to their pains and pleasures. This indifference characterises all animals, many children, and some men, in whom the sensational element is unduly preponderant. What civilisation and society would be without sympathy, it is diffi- cult, or rather it is not difficult, to imagine. Neither society nor civilisation could exist. Such would be the consequence if people had merely the feeling of themselves and of their own sensations, appetites, and desires. 27. If we now turn to the consideration of self- consciousness, or the conception of oneself and of one's own pains and pleasures, a conception which I246 GREEK PHILOSOPHY. supposed you might be inclined to confound with the mere feeling of oneself; if we turn to the considera- tion of this conception of oneself, we shall perceive how completely it is distinguished from the feeling, both in itself and in its consequences. It has been already explained to you that thought in all cases embraces something more than is directly and obtru- sively thought of; that it extends beyond the parti- cular to the universal; that when a sensation is felt and thought of, other sensations are thought of as well. In the same way the thought of me extends to other mes. When I have the conception of myself, this conception is the conception of all mes, and not merely of me in particular. When I feel myself and my own sensations, I do not, cannot, feel another man and his sensations; but when I think myself and my own sensations, I think other men as well, virtually all other men and their sensations. I think myself and'my pains and pleasures as an instance of which there are or may be myriads of other instances. Mere feeling, the mere feeling of myself and my sensations, would never enable me to do this. But thought enables me, indeed thought compels me, to do it. Thought clears the bounds of mere feeling; thought, in the very act of being what it is, neces- sarily overleaps the limitations of feeling. Hence thought, the thought of oneself and of one's sensa- tion, is the ground and the condition of sympathy. Without this thought there can be no sympathy; but along with this thought, sympathy more or lessSOCRATES. 247 arises. Sympathy lies at the root of civilisation and of society. Hence all that is good in man's condition is founded ultimately on the power of thought, in that act in which the mind disengages itself from its own particular self, and from its own particular sen- sations, appetites, and desires, and takes into account other people and the interests of other people as well. Society, with all its beneficial institutions, thus arose out of thought, out of self-consciousness, out of the conception of oneself; whereas the mere feeling of self would for ever prevent society from being established among men, would for ever envelop the world in the darkness of barbarism, and keep away the dawn of civilisation. 28. The whole social edifice rests ultimately upon the freedom of thought, and arises out of it. First, there is freedom, that original and uncaused act by which the mind thinks itself, its own sensations, appetites, and desires, and in doing so frees or dis- engages itself from them; or, stated with equal truth in the converse way, that original and uncaused act by which the mind disengages itself from itself, from its own sensations, appetites, and desires, and in doing so thinks them: for, as I formerly said, the disengagement and the thought, the freedom and the conception, are identical; and we cannot say which comes first and which second; they are simul- taneous in their operation. Secondly, there is self- consciousness, the consciousness or conception of one-248 GREEK PHILOSOPHY. self and of one's own sensations. But inasmuch as all thought is a disengagement from that, whatever it may be, which more obtrusively occupies the mind, and is thus a getting beyond and away from the par- ticular, so, in the conception of self, I am not tied down to my own individual self: my conception extends beyond this, it embraces, in fact, the whole human race. It is not possible for me to think my- self merely. In thinking myself, I think all other selves. Note here the very marked antithesis be- tween feeling and thought. In feeling myself, I must feel only my particular self, and I cannot possibly feel others as well. In thinking myself, I cannot think only my particular self; I must of necessity think others as well. Thirdly, there is sympathy. This arises out of self-consciousness. The conception of myself being the conception of other selves as well as of me, not only enables, but compels me to take some interest, more or less, in them as well as in myself. Thus sympathy has self-consciousness for its foundation. Self-consciousness is the condition of sympathy, and not only that; wherever self-con- sciousness is manifested, there some degree of sym- pathy must be put forth. In virtue of self-conscious- ness, sympathy is not only possible, it is also actual and imperative. Fourthly, there is society. This arises out of sympathy. Without a fellow-feeling, mutual goodwill, and a community of sentiment, society could not subsist for a day, social inter- course would be impossible; so that freedom ofSOCKATES. 249 thought is ultimately, and at bottom, the lever which raises man up into the position in which we now find him existing. It is the root out of which spring all the blessings of civilisation. Take this away, and it would resolve human society into a commonwealth, or, I should rather say, an anarchy, of kangaroos or ourang-outangs. 29. The doctrine which I have just propounded in regard to the relation between self-consciousness and sympathy may enable us to modify Adam Smith's theory of moral sentiments, which has been already under our review; and to render that theory, if not impregnable, at any rate more complete than it now is. Adam Smith, as you are aware, explains our moral sentiments by means of the principle of sympathy. Our faculty of moral estimation, our power of passing moral judgments either on ourselves or on others, is resolved by him into our power of sympathy, and is indeed nothing but the operation of this principle. But in working out this system Adam Smith seems to have thought that sympathy is a native and original affection of the human heart, just as hunger and thirst are natural affections of the human organism. He seems to have thought that people felt sympathy for others just as naturally as they felt their own pleasures and their own pains. This opinion I regard as incorrect. I hold that we have originally, or in the first instance, no sympathies with other people in the way in which we have origi-250 GREEK PHILOSOPHY. nally, and from the very first, a sense of our own weal or woe. I conceive that we become sympathetic only after the idea of self has been called forth, and this is an idea which does not show itself in our very early years. But until it does declare itself, our sympathy has no existence. In proof of this you have only to observe how little sympathy very young children have in the sufferings or enjoyments of each other. In them the idea of self is either not devel- oped at all, or it is but feebly developed; the mere feeling of self is predominant or all-absorbing, and hence they are wrapped up in their own sensational and emotional world, and take little or no interest in the happiness or misery of their companions. But gradually as this idea unfolds itself, the emotion of sympathy begins to dawn. In the light of this con- ception they see that others are just themselves over again; and, taking an interest in themselves, they come to take an interest also in all those whom the idea reveals to them as fashioned after the same model with themselves. The idea of self is no ex- clusive or egotistic principle; the feeling of self is egotistic and exclusive; but the idea of self is uni- versal and comprehensive. It is the true equaliser of the human race. It is the principle which enables us to understand and, so far as the mere individual feeling will permit, to act according to the Divine pre- cept of doing to others as we would that they should do unto us. Thus self-consciousness, as was formerly explained to you, is essential to the existence of sym-SOCKATES. 251 pathy, and sympathy is thus a passion which, unlike our more elementary appetites and desires, has its roots in thought, and is brought about through the intermediation of an idea. This circumstance has, I think, been overlooked by Adam Smith. 30. If Adam Smith erred in regarding sympathy as an affection of as original and elementary a char- acter as our appetites and some of our desires, Hobbes erred, on the other side, in regarding it as forming no part of man's original nature at all, but as a second- ary and derivative formation springing out of fear, which made men combine into societies for mutual aid and protection against other societies which might be disposed to do them harm. Hobbes denies that man has by nature any sympathy with his fellows. He holds that all our original passions and instincts are unsocial, or, indeed, antisocial; and in entertain- ing this opinion, Hobbes, I think, is so far right. He is right thus far, that prior to the dawn of self-con- sciousness, all our principles of action, our appetites, affections, and desires, are unsocial; they aim merely at the attainment of our own personal pleasure, and at the avoidance of our own personal pain. But after the dawn of self-consciousness, the social affec- tions are developed, sympathy comes into existence, and this sympathy is as truly a part of our nature as any of our other affections are; the only difference between it and those which are more primitive being this, that it (sympathy, namely) exists only after252 GREEK PHILOSOPHY. self-consciousness has declared itself, whereas the others exist before that idea has been called forth. And hence Hobbes, although, as I said, to some ex- tent right, is also so far wrong, inasmuch as he scarcely seems to admit that sympathy is in any sense natural to the human heart, or a natural attri- bute of man. He is, however, right in his opinion that sympathy is not so original, so natural to man, or at least so immediately manifested, as those appe- tites and desires which show themselves in the earli- est period of his existence, and spring up without the intermediation of thought, or of any idea being required for the manifestation. 31. But these latter remarks are somewhat digres- sive. I return to the subject with which we are more properly engaged. You should now perceive how directly the results which we have reached strike at the root of Sophistical argumentation. Socrates meets the Sophists on their own grounds, and foils them with their own weapons. Assenting to their leading principle, he may be supposed to address himself to them thus, " Whatever is natural, you say, is more authoritative than anything which is conventional; vofjuo^ must always give way to I grant it; but what is vvai<;, and this I admit, is more authoritative than any vofjuos, than any convention or agreement among men. But what does this nature enjoin ? What are the ethics of nature now when thought is taken into account as forming the principal part of man's nature ? They must be very different from the ethics evolved out of a psychology which either takes no notice of thought, or resolves it into a mere form or product of sensation. They must enjoin something very differ- ent from what is enjoined by the code of Sophistical or sensational morality, and they do enjoin something very different. The ethics of sensation say, Follow out your sensations, gratify them to the full, and at all hazards please your appetites and your desires to the uttermost, for sensation and its adjuncts, appe- tite and desire, constitute the true nature of man. But my code of ethics (I still suppose Socrates speak- ing), my code of ethics say no. Thought is the true nature of man. Therefore you must follow out what thought involves and what thought prescribes, for then alone will you be obeying that vcrn; which, on your own showing, is the most obligatory and authoritative of all things. But if thought be the essence of man, the essence of thought, as has been already sufficient- ly explained, is freedom, is a liberation from sensa- tion, appetite, and desire. Thought is itself, as we have seen, a disengagement from these, not that man in thinking is ever without sensation of one kind or254 GREEK PHILOSOPHY. another; but man in thinking is always free from their dominion. Self-preservation is the first of duties; but the preservation of our thinking, that is of our true, selves, can be effected only by laying a restraint on our sensations, appetites, and desires, and by refusing to be their slaves. Thus alone is that self preserved which consciousness or conception re- veals to us as our true self. It exists and maintains itself only through an antagonism perpetually waged against those otherwise enslaving and monopolising forces, our sensations, passions, and desires. Our nature is, as you say, the most authoritative of all things, and we are under the most stringent obliga- tion to obey its commands. But we obey these com- mands not when we yield to the dictates of sensation, appetite, and desire, but when we antagonise these forces, and hold them at bay by means of that freedom of thought which is our birthright and our essence." So far we may suppose Socrates to speak. 32. I now remark, in my own name, that the ethics of nature, as expounded by Socrates, are shown to be in harmony, for the most part at least, with the ethics of society. $vgi? and vo/jlos are reconciled. Society merely enforces what nature has already prescribed. Thus the contradiction between the natural man and the conventional man, on which the Sophists were wont to lay so much stress, is overcome and ap- peased. The social man is merely the develop- ment of what man is in himself. The citizen isSOCRATES. 255 merely the perfection of the individual. The state itself is nothing but the individual in a brighter form, and in more enlarged proportions. 33. The foregoing details may perhaps have en- abled you to form a tolerably adequate conception of the groundwork of the moral philosophy of Soc- rates, both in its polemical character as a refutation of the Sophists, and in its positive character as a body of sound and scientific ethical doctrine. I have gone into the controversy between Socrates and the Sophists at considerable length, because I con- ceive that in this controversy are to be found all those elements of dispute which again and again have divided the philosophical world both in ancient and in modern times. We shall see hereafter, in particular, that the controversy between Hobbes and his opponents—at the head of whom stands Butler as one of the most conspicuous, although other moral- ists (Cudworth, for example) had entered the lists before Butler appeared—we shall see, I say, that this controversy bears a close resemblance in some of its features to the polemic carried on two thousand years before between Socrates and the Sophists. Hobbes took up the ground of sensationalism as the basis of his philosophy very much as the Sophists had done before him, and he found no principle of pacification among men, no curb for their unruly appetites and passions, except the strong and armed hand of a supreme and irresponsible dictator. But-256 GREEK PHILOSOPHY. ler attempted to show that principles of pacification existed in the nature of man himself in his social instincts and benevolent affections. In this attempt Butler was merely treading in the footsteps of Soc- rates, although with a feebler and less scientific step. Socrates had, I conceive, a deeper insight into the nature of man than Bishop Butler. Instead of re- garding, as Butler did, our social and benevolent affections as original parts of our nature, in the same sense in which hunger and thirst are original parts of our nature, Socrates regarded them as brought about through the intervention of thought. So, at least, I am inclined to interpret his philosophy. He re- garded these social affections as having no place in the economy of man until after his self-consciousness had been called forth; and in this opinion Socrates seems to me to be unquestionably right. Butler, however, regards the social affections as standing on the same footing with hunger and thirst, affections which certainly declare themselves prior to any manifestation of self-consciousness. So far, there- fore, I am of opinion that the Athenian sage was superior to the English bishop both in speculative depth and in scientific precision. But, without in- sisting on that point, what I wish you to observe is, that my reason for going at such length into the moral philosophy of Socrates is because I conceive that by laying down thought, or, more strictly, the free act of self-consciousness, as the groundwork of ethics, it supplies the truest of all foundations for aSOCRATES. 257 system of absolute morality, and contains the germ of all the ethical speculations, whether polemical or positive, which have been unfolded since his time. 34. I shall make no further attempt at present to reduce the philosophy of Socrates to greater preci- sion than has been done in the foregoing exposition. I go on to call your attention to a few points con- nected with Socrates and his philosophy, with which you should be made acquainted before we dismiss this subject. The first point is, that all rational know- ledge must be elicited from within the mind, and cannot be imparted to it from without. The Socratic art of education, therefore, consists rather in a skilful method by which the mind is made to evolve truth out of itself, than in a method by which truth is communicated to the mind by another person. The second point is the somewhat paradoxical assertion, that all virtue is knowledge and all vice ignorance. The third point is the assertion that no man is volun- tarily vicious. The fourth point for consideration is, What, according to Socrates, is the supreme good, the chief end, of man ? The fifth consideration is, What, in the system of Socrates, is the ground of moral obligation ? The sixth point for consideration is, How virtue and happiness are reconciled and united in the system of Socrates. On some of these points it may be difficult, perhaps impossible, to come to any very satisfactory conclusion; but I shall do what K258 GKEEK PHILOSOPHY. 1 can to throw light upon them, by saying a few words upon each. 35. First.—In several parts of the Dialogues of Plato, Socrates announces himself, with considerable humour, as a person devoted to the same calling as his mother Phaenarete, who practised the obstetric art; the only difference between them being that, whereas she assisted women with her skill, he helped to deliver the minds of men of the ideas of which they were in labour. The analogy between his mo- ther's profession and his own was referred to by Socrates in order to show that he could no more impart, and that it was no more his business to impart, truth and knowledge to the minds of his hearers, than it was her business to bear the child, and impart it to those whom she was called upon to deliver. In both cases it was their business to elicit something from within, and not to communicate any- thing from without. More particularly was this true in regard to the birth of intellectual knowledge; for, according to Socrates, the mind contained within it truths which external experience or communication with others might call forth, but which no external experience and no communication with others could instil or impart. The mind must originate them with- in itself. As an example of this kind of truth, the whole science of mathematics may be adduced. In the dialogue of Plato entitled Meno, Socrates is repre- sented as educing from the mind of a young slave, bySOCRATES. 259 means of judicious questioning, some of the more ele- mentary truths of geometry. As a very simple illus- tration, I may take a geometrical axiom, and I ask a person quite unskilled in mathematics, whether, if equals be added to equals, the wholes will be equal or unequal. If he understands the question, he will at once answer that the wholes will be equal. But I did not teach him that truth; no one imparted it to him. I merely put the question to him, and he found out for himself the right answer for himself at once. It sprang up within him; and if it had not sprung up within him, he never could have received it from without. If a student of geometry were to say, My reason for assenting to the axioms is because Euclid or my teacher has assured me that they are true, and I take their word for it—if a student, I say, were to speak thus, he would show that he had no understanding of the simplest elements of geometry. But what you have to observe is, that the whole science of mathematics is truly of the char- acter which Socrates describes. The just inference is, that the entire science is properly, even in its most complicated demonstration, called forth from within the mind, and not communicated to the mind from without. In Plato's hands this doctrine passed into the assertion that all knowledge is reminiscence; is the recollection of what the mind knows, and actually knew in some former state of existence, and still potentially knows. Such a doctrine must be limited to what may be called rational knowledge,260 GREEK PHILOSOPHY. the knowledge of necessary truths, as distinguished from historical knowledge, which certainly cannot be elicited from the mind by any process of manipu- lation, however skilful. But it is only of rational knowledge, knowledge which depends altogether on thinking, that Socrates and Plato speak. In sub- sequent times this opinion—all rational knowledge is reminiscence—has reappeared in the doctrine of innate ideas; a doctrine which Locke was supposed at one time to have completely overthrown and ex- tirpated, but which has so much vitality that it has shown itself again and again since his time, and flourishes even now with renovated youth and vigour. The ultimate ground of this opinion is to be found in the doctrine I formerly explained to you, the doc- trine of thought as a free and self-originated act. No external power, no force brought to bear upon him ab extra, can make a man think; because thinking is in fact a freedom from all external compulsion, and a rejection thereof; therefore a man must think, if he thinks at all, for and from himself. He cannot be made to think at the bidding and under the com- pulsion of others, as he may be made to feel at the bidding and under the compulsion of others. Hence every science, the truths of which are truths of thought, must be called forth from within the mind of the learner, and cannot be impressed upon him from without. 36. The second point is the assertion that all virtueSOCRATES. 261 is knowledge, and all vice ignorance. This appar- ently paradoxical assertion may perhaps be inter- preted in this way: If a man only knew and kept constantly in view what his true nature was, he would aim only at that which conduced to the well- being of that nature; and aiming only at this, he would be unwavering in the practice of virtue, for it is by virtue alone that the wellbeing of his true nature is secured. For example, if a man knew and never lost sight of the knowledge that thought is his true nature, that freedom is the essence of thought, that thought is the antagonist of sensation, passion, and desire, that it is by thought that man is disen- gaged from these, the enslaving forces of his being, and established in this true personality;—if a man knew, and kept constantly in view, that such was his true nature, he would aim at the preservation and wellbeing of that nature by laying a suitable restraint on those lower impulses and propensities which at all times threaten to invade and impair it, and thus he would continue steadfast in the pursuit and practice of virtue; for virtue is nothing but a restraint laid upon the natural lusts and passions of the soul. Hence, if man's knowledge of himself was perfect, his virtue too would be perfect; and in pro- portion as his knowledge approaches to perfection, so too would his virtue approach to perfection. But man's knowledge of himself is, for the most part, not only imperfect, it is absolutely null. His ignorance of his true nature is such, that he mistakes for his262 GREEK PHILOSOPHY. true nature that which is not his true nature at all. He thinks that his true nature centres in his sen- sations, appetites, and desires; hence he conceives that his true wellbeing will be promoted by an in- dulgence in these as unlimited as can be procured. Hence he falls into vicious courses. But this hap- pens in consequence of his ignorance; of his ignor- ance of what constitutes his true nature, and of his consequent ignorance as to the means by which the wellbeing of that nature should be promoted. Thus, as all virtue has its origin in knowledge, in a know- ledge of what our true nature is, so all vice has its origin in ignorance, in an ignorance of what the nature of ourselves really and truly is. This farther may be said: whatever man pursues, he pursues in the idea that it is good for him. When he pursues evil, therefore, he does so because he mistakes it for good; in other words, he does so in ignorance of its true nature. Had he distinctly known what this, its true nature, was, he would have avoided the evil after which he is running. More shortly stated, no man runs after evil viewed as evil, but viewed as good: he embraces evil under the disguise of good; that is to say, he embraces it unwillingly. This doctrine is in keeping with the Socratic position, that all vice is a sort of madness, and that the perfection of virtue is the perfection of sanity, or reason, or wisdom. Aristotle has objected to Socrates, that, in reduc- ing virtue to knowledge, he has emptied our vir- tuous affections of that warmth and heartiness bySOCEATES. 263 which they are characterised. His objection is not without force, and it shows that the Socratic doctrine is not altogether complete. So far as it goes, however—and I think it goes a long way in rendering virtue intelligible—it seems to me to be a sound and rational speculation. 37. The third point is, that no man is voluntarily vicious. This conclusion follows as an immediate corollary from what was said in the preceding para- graph. No man wills to do that which is adverse to his true interests. But a man may mistake his false for his true interests; hence he may enter on a course of action which is at variance with his true interests, and thus he may fall into vice. But he cannot be said to will this vice; for all the while he is willing to promote his own true interests, only, through ig- norance as to what these are, he has fallen on a course of conduct which secures only his false interests and promotes only his false happiness; and this is the way of vice, and not the way of virtue. Hence it is only through ignorance of his own true interests that a man is vicious, and not because he wills to be so, for a man wills only his true interests; and if he always knew what these were, he would continue in the practice of virtue, for virtue alone can secure them. 38. The fourth point for consideration is, what, according to Socrates, is the supreme good, the chief264 GREEK PHILOSOPHY. end of man ? I conceive that Socrates agreed with all the ancient moralists in holding that his own happiness is the supreme good, the chief end of man. But then this happiness must be his true, and not his apparent or illusory, happiness; but man's true happiness must centre in his obedience to the law of his true Being, and not in his obedience to the dictates of his unessential Being. But the law of man's true being is freedom; freedom from the yoke of sensation, passion, and desire. Therefore man's proper happiness, his supreme good or chief end, is to be found in a due subjugation of our appetites and desires, and not in their unqualified indulgence, as is inculcated by those moralists who, not knowing themselves, do not know what the true and essential nature of man is. 39. The fifth point for consideration is, what, in the system of Socrates, is the ground of moral obliga- tion ? T conceive that, in the system of Socrates, the ground of man's moral obligation is to be found, where we have already found his happiness or chief end; is to be found, that is, in his true nature itself. Freedom from the dominion of his lower affections, his sensations, appetites, and desires, is the true nature of man. He is, therefore, under an obliga- tion to maintain this nature, for self-preservation is the most indefeasible law of the universe; but he can only maintain it by keeping up that disengage-SOCRATES. 265 ment from sensation, appetite, and desire which thought, his true Being, had already effected even in bringing itself into existence. In his own nature, therefore, there is a law, the law of freedom, which calls upon him to restrain his lower impulses, his greed and his injustice, when these threaten to be- come inordinate; and this law of freedom is no other than the law of moral obligation, and it has its ground in the true nature of man. 40. These points having been explained, it is not difficult to see how happiness and virtue, the sixth point under consideration, are reconciled and united in the system of Socrates. The true nature of man consists in thought, but the essence of thought is freedom; freedom, or disengagement from the bond- age of his lower principles and propensities, such as sensation, appetite, and desire. Thus the law of man's true nature is freedom, freedom from thraldom of his lower propensities. But the happiness of every creature is promoted when it obeys the law of its true nature; its happiness is thwarted when it disobeys that law, therefore man's happiness is pro- moted when he keeps himself disengaged from the sensational affections of his nature, and does not allow them to overmaster him. But this resistance to the promptings of our passions is itself virtue. Therefore the same law, the law of freedom, which determines a man to happiness, to his true and solid266 GREEK PHILOSOPHY. happiness, through the subjugation of his animal propensities,—this same law determines him also to virtue, for virtue is nothing but the subjugation of these same animal propensities; and thus happiness and virtue are shown to be coincident.THE CYRENAIC, CYNIC, AND MEGARIC SCHOOLS. 1. The impression which Socrates made on the minds of his countrymen generally, and even on men who differed widely in their genius, their char- acter, and their sentiments, was deep and powerful; and his influence was not diminished, it was rather increased and rendered more intense and lasting, by his heroic and signally impressive, although unos- tentatious, death. Socrates having left behind him no written memorials, all that his friends could do would be to record and publish his opinions as they had gathered them from his own lips. And these opinions would be coloured and modified more or less by the peculiar mental constitution of each reporter; or, at any rate, each would fasten on that side of the Socratic philosophy which he understood best, and which was most in harmony with his own convictions. Accordingly, we find that some of the disciples of Socrates expounded his philosophy, in its more popular aspect, as a useful guide in the practical affairs of life; among these the most dis-268 GREEK PHILOSOPHY. tinguished were Xenophon, who in his ' Memorabilia' has recorded the sayings and doings of Socrates in their bearings on the business of mankind, and Cebes, to whom a work is questionably attributed entitled IIiva%, or the Table, which sketches, on So- cratic principles, an allegorical picture of human life. Its moral is to show that virtue alone can make us truly happy, and that pleasure is a snare and a delu- sion, whose charm lasts only for a time. Others, again, or I should rather say one other of his imme- diate followers, comprehended the whole scope and design of his philosophy; and this disciple was Plato. Plato alone fathomed the depths, both moral and metaphysical, of the Socratic speculations. He has interfused them with the splendours of his own genius, and has given them to the world in a style, the eloquence of which has never been sur- passed, if indeed it has ever been equalled. Plato stands out as the only adequate exponent and repre- sentative of the Socratic philosophy in all its phases. But, intermediate between Plato on the one hand, and the popular expositors just referred to on the other hand, there are presented to us three schools of Socraticists, who, being more scientific in their treatment of the philosophy than Xenophon or Cebes, are at the same time much less complete and comprehensive than Plato. These three Socratic sects are the Cyrenaic, the Cynic, and Megaric. They are frequently termed the imperfect or one- sided Socraticists.CYRENAIC, ETC., SCHOOLS. 269 2. How these schools arose, and how they acquired the title of imperfect Socraticists, may perhaps be understood from the following consideration: The conception of "the good" was a conception which had been largely insisted on in the philosophy of Socrates; but it was, at the same time, one which he had left indefinite and unexplained. Nowhere, and at no time, does he seem to have explained ex- actly what " the good " was, or what he precisely and consistently meant by that term. That Socrates regarded happiness as the good, is tolerably plain; but then it is equally plain that he regarded virtue as the good. Hence arose ambiguity, and hence arose confusion and discord among his disciples. It is no answer to the question, What is the good ? to say the good is both happiness and virtue; for by the good is meant the ultimate, the supreme, or highest good; and two goods cannot, both of them, be the highest, at least their conciliation requires to be explained; in all cases the supreme can be only one. If, indeed, the identity of the two had been established in some such way as I endeavoured to establish it above (p. 265), following out what I conceive to be the drift of the Socratic speculations —if their identity had been established, then perhaps the question as to the supreme good or chief end of man might be admitted to have been sufficiently answered. It might have been said, the good is the identity or conciliation of happiness and virtue; and that answer would have been unambiguous. But this270 GREEK PHILOSOPHY. conciliation had not been effected, or effected but ob- scurely and ijnperfectly, in the course of the Socratic disputations. Hence the question still remained unresolved, and still recurred, What is this good which is so frequently and earnestly insisted on ? is it happiness or is it virtue ? Which of these is the summum bonum, the chief end, of man ? Their re- duction to unity had not been clearly shown, so that the one or the other of these alternatives had to be chosen. The Cyrenaics chose the alternative which placed the good or chief end of man in happiness. The Cynics chose the alternative which placed the good or chief end of man in virtue. I believe that the Socratic philosophy contained, as I have said, a principle by which these two, happiness and virtue, were conciliated and made one; but this principle had not been fully developed; and these two sects, the Cyrenaic and the Cynic, did nothing to develop it. The one of them dwelt on happiness as the ultimate good of man, almost to the exclusion of virtue; the other dwelt on virtue as his ultimate good, making happiness altogether subordinate. 3. The question in regard to happiness has been much debated in almost every school of moral phil- osophy—in those of ancient, no less than in those of modern, times. It is, indeed, the cardinal ques- tion of ethics; for although some systems endeavour to shelve this question, and to bring conscience andCYKENAIC, ETC., SCHOOLS. 271 virtue and duty more prominently into the fore- ground as the proper topics of ethical investigation, still I believe that these latter can receive an ade- quate and intelligible explanation only when con- sidered in subordination to the more comprehen- sive discussion which has happiness for its theme. Schemes of morality may err in two ways—either by representing duty and virtue as ultimate ends, to the exclusion of happiness, or by representing happi- ness as the ultimate end, to the exclusion of duty and virtue. In either case we obtain a system which is incomplete, one which is neither sound in itself, nor likely to meet with any general acceptance. Pure Eudaimonism, which teaches that happiness is all in all, however acceptable it may be practically, is a doctrine which cannot be theoretically approved of; while Asceticism, which contends for the abnegation of happiness in the pursuit of duty and virtue, is a scheme which will never enlist many practical ad- herents, however numerous its theoretical advocates may be. The only way of avoiding the errors inci- dent to either extreme, and of effecting a rational compromise, is by instituting an inquiry into the nature of human happiness, with the view of ascer- taining the relation in which it stands towards con- science and virtue and duty; and accordingly it is to this question that we now deliberately address ourselves. 4. The inquiry concerning happiness resolves it-272 GREEK PHILOSOPHY. self into two questions—First, Is happiness the chief end of man ? and, secondly, Ought happiness to be the chief end of man ? The one of these questions is a question of fact, Is the fact so ? The other of them is a question of propriety, Ought the fact to be so ? Although our answers to these questions may ulti- mately coincide, and we may find that what is, is what ought to be—in other words, that happiness both is and ought to be the chief end of man—it may still be well to keep the two questions separate at the outset, and to treat of each in succession. 5. The philosophy of the Cyrenaic school, founded by Aristippus, proceeds on the assumption that hap- piness is, in point of fact, the good, the supreme good, or chief end of man; and this assumption, so far from being discountenanced by the philosophy of Socrates, is involved in that philosophy as one of its most vital principles. Viewed as a matter of fact, we must admit that his own happiness, whatever it may con- sist in, or whatever may be the means to be employ- ed in the attainment, is the end which each indivi- dual has most at heart, and at which he ultimately aims. This is the end after which all men most eagerly strive. Happiness is the goal which, con- sciously or unconsciously, we are all struggling to reach. Milton has written two epic poems in which he commemorates our fallen and our restored condi- tion. He has written ' Paradise Lost' and ' Paradise Regained/ But the true epic of humanity—the epicCYKENAIC, ETC., SCHOOLS. 273 which is in a constant course of evolution from the beginning until the end of time, the epic which is daily poured forth from the heart of the whole human race, sometimes in rejoicing pseans, but oftener amid woeful lamentation, tears, and disappointed hopes— what is it but Paradise sought for ? 6. Hence there has been a tendency in the minds of all men, whether rude or civilised, both in ancient and in modern times, to accept this fact as they found it; to set forth happiness as the summum bonum, the supreme good, the ultimate end of all human en- deavour, the magnet whose power of attraction no human being could successfully resist. The gen- eral tendency of opinion, I say, has been to acknow- ledge the universal dominion exercised over man by the desire of happiness, and to accept this principle as his supreme rule of action, and as the basis of all ethical disquisition, whether practical or theoretical. To have denied that happiness was man's chief good and his ultimate aim, would have appeared to be fly- ing in the face of truth, and setting nature herself at defiance. 7. But although philosophers, as well as mankind at large, have generally agreed that happiness is the greatest good, or the chief end of man, philosophers have differed as to what happiness itself is—as to what it consists in. By an easy transition, some people come to regard happiness as convertible with s274 GREEK PHILOSOPHY. self-indulgence, or as centring in mere sensual plea- sure. This was the most palpable, most vivid, and most intelligible sort of happiness with which they were acquainted ; while physical pain, on the other hand, was the only misery which they could readily understand: and accordingly, in the early and rude periods of society, sensational pleasures were eagerly pursued, as the only true and distinct constituents of happiness, while sensational pains were carefully avoided, as the only true and distinct constituents of misery; and these are regarded as the true elements of happiness or of misery. Of course, instances would occur, even during such times, in which indi- viduals, and even multitudes, would encounter dan- ger and death under the excitement of some strong passion. But I speak of man in his ordinary state, and when left to the guidance of his natural and normal inclinations. These would prompt him to court sensational pleasure, and to shun sensational pain, whenever it was in his power to do so. 8. This, accordingly, was the opinion entertained by Aristippus in regard to happiness. He viewed it as convertible with pleasure; and in this respect he differed widely from the sentiments of Socrates, who, whatever his opinion as to happiness may have been, certainly did not regard it as centring in the plea- sures and enjoyments of sense. Thus Aristippus, dissenting from the opinions of his master, although he may have supposed that he was reducing theseCYRENAIC, ETC., SCHOOLS. 275 opinions to greater clearness and precision, and con- ceiving happiness in its most obvious and palpable and intelligible form, in the form in which it was viewed by thfe vulgar, advocated a system of hedon- ism, as it has been called, from the Greek word rj^ovrj, in which mere sensual pleasure is set forth as the great good and ultimate end of man. 9. It is evident that the sensational ethics of Aris- tippus had their roots in the sensational psychology, of which I have already spoken at sufficient length in expounding the opinions of the Sophists. They arose, not out of the comprehensive and profound 7vS)6l aeavrov of Socrates, which resulted in the dis- covery that the true nature and essence of man was thought, but out of the superficial and contracted something different from this; it is happiness, the happiness of himself and others; in a word, his conduct is now tested by its utility, that is, by its tendency to pro- mote or to obstruct the interests and wellbeing of himself and of mankind. 23. It now then appears as if we had two chief ends set up as the proper objects of human pursuit. t290 GREEK PHILOSOPHY. The one end comes before us when we put happiness and misery aside, and look at man simply as man. In this case the proper end of all his actions and aspirations will be to maintain and strengthen his true being; that is to say, his rational nature. The other end comes before us when we take happiness and misery into account, and view man as suscepti- ble of these qualities. In this case, the proper end and aim of man's existence will be the attainment and the diffusion of happiness. Both should be treated and adjusted in a complete system of moral philosophy. 24. Now it may often happen that there will be no discrepancy between these two ends. We may admit that they are usually in harmony with one another, and that in attaining the one end we attain the other as well. But cases must, and do, occur in which both of these cannot be attained; cases may occur in which a man, in attaining what he conceives to be, and what indeed is, his happiness, must sac- rifice the perfection of his rational being; or again, cases may occur in which a man, in maintaining the perfection of his rational being, must sacrifice what he feels to be his happiness. In these cases, which end must he cling to, and which end must he give up ? I answer that he must cling to that end which consists in the preservation and perfecting of his rational nature, and must give up that end which consists in happiness or pleasure, whether that hap-CYRENAIC, ETC., SCHOOLS. 291 piness be his own or that of others; and I give this answer for this reason, that it is of more importance that man should be a man, truly a man, than that he should be a happy man. To be happy, we must first of all be men, and to be men we must first of all be rational. Whatever, therefore, strikes at the root of reason or thought is to be avoided, however much it may promote our happiness, for our reason is our existence. But it does not follow that what- ever strikes at the root of our happiness is to be avoided, however much it may promote our rational perfection, for our happiness is not our existence. On these grounds I conceive that when the two ends come into conflict, the preference is to be given to that end which is regarded by man considered as man simply; for this end, its preservation and at- tainment, is his very essence and existence: and that the preference is not to be given to that end which is set in view before man considered as susceptible of happiness and misery, for in this end his essence and his existence do not centre, happiness and misery being merely accessories to human nature, and not human nature itself. 25. In the latter part of yesterday's lecture XI was led into a discussion of a somewhat digressive char- acter. It arose out of the ambiguity in which Soc- rates had left the conception of the good, meaning by that word the great and proper object of all human pursuit. Is happiness the chief end of man?292 GREEK PHILOSOPHY. Is this the object which he is designed unremittingly to pursue on his own account, and to the utmost of his ability to diffuse on account of others ? Or is virtue his chief end ? Is the right as distinct from the useful, the just as distinct from the expedient, the object which it is his duty to strive after ? Socrates does not seem to have returned any very explicit answer to this question; and hence he has not settled definitely what the good for man is, inas- much as he has not declared categorically whether it is happiness or virtue. From the spirit of the Socra- tic teaching we may infer that he regarded virtue as the supreme good; but the scientific grounds on which he rested this conclusion are not apparent. Nor are they apparent in the writings of any subse- quent moralists. Many moralists have declared that we must do what is right at all hazards, that we must act rightly irrespective of all considerations of utility. And when we ask why ? why must we act rightly ? the only answer we get from them is, that we must act aright because it is right to do what is right. This mode of reasoning—and I believe it is a fair representation of the reasoning of Dr Whewell and the other anti-utilitarians—is not very satis- factory. The anti-utilitarian moralists may, however, be regarded as returning an articulate answer to the question, What is summum, bonum, the chief end of man ? They declare that it is virtue. 26. On the other hand, the utilitarians or Eudai-CYRENAIC, ETC., SCHOOLS. 293 monists define the good as centring in happiness. To act aright is to act in such a way as will promote either our own happiness or the happiness of those around us, or the happiness of the world at large. Whatever conduct has this effect is right conduct; whatever conduct has a contrary effect is wrong con- duct. In answer, then, to the question, Why must I do what is right ? the utilitarian answer is, Because by so doing you will contribute something to the well- being of the world. It is your duty to act in a par- ticular way, in the way which we call right, because by acting in this way you will promote the happiness of yourself and others, and will thus attain the end which all human beings are born to strive after. Here, also, we have a categorical answer to the question, What is the summum bonum, the chief end of man ? The utilitarians declare that happiness is the good. 27. This theory of the good which makes it con- vertible with happiness seems to labour under a defect precisely the opposite of that which we charged against the anti-utilitarian scheme. There we were disposed to accept the conclusion, but to find fault with the premises as insufficient or null. Here we are indisposed to embrace the conclusion, although the premises seem reasonable and strong. That a particular action should redound to the advantage of myself or others seems a very sufficient reason why it should be performed. The advantage expected to arise from it seems to make the performance of it a294 GREEK PHILOSOPHY. duty. That is an intelligible position, more so than the ground occupied by the anti-utilitarians. We feel, nevertheless, that there is something defective in the scheme which sets aside virtue as the good, and enthrones happiness in its place. So far as we can see, there is a flaw somewhere in the system of the utilitarians, and also in the system of their opponents. We are not willing to throw virtue overboard, and join the utilitarians in setting up happiness alone as the supreme good for man; nor are we willing to join their opponents in throwing happiness over- board, and in setting up virtue alone as the ultimate object of his pursuit. We must try whether we can- not fall on some method by which the two, virtue and happiness, may be conciliated, conciliated on scientific grounds. 28. It was as a step towards this conciliation that I drew your attention, in my last lecture, to a dis- tinction which may be of service to us in our attempt to adjust and to resolve this difficult moral question as to the supreme good: I mean the distinction be- tween man considered as man simply, and man con- sidered as susceptible of happiness and of misery. I stated what was meant by man simply, and what his qualities were, and also what man was in his more complex condition as the subject of happiness or the reverse. I stated that a different system of morals would apply to him in the simple state from what would apply to him in the complex state; inCYKENAIC, ETC., SCHOOLS. 295 other words, that the good or ultimate end would be different in the case of man simply, from what it would be in the case of man as capable of happiness and of misery. In the former case, it would be the preserving and the perfecting of his rational nature; in the latter case, the end would, to a large extent, be happiness or pleasure—that is, something less inti- mately connected with himself than the perfection of his intelligent nature. I also stated, that these two ends might frequently coincide, in which case no collision would arise; but they also might come into conflict, and when this happened, I stated that the end called happiness must be sacrificed in favour of the other end, which we may very well call virtue. I also gave you my reason for this conclusion, and it is one which, though then briefly stated, appears to me to be more scientific, logical, or reasonable than any which I have yet fallen in with. Stated again, very shortly and simply, the reason why we should sacrifice our happiness to our virtue is this, that in sacrificing happiness to virtue we do not cease to be men, we only cease to be happy men; but in sacri- ficing virtue to happiness, we do cease to be men, because virtue is the preservation and perfecting of our rational nature, and therefore whatever is at variance with virtue is at variance with the preser- vation of our true being, and is pro tanto a curtail- ment or destruction of our moral and intelligent life. 29. Let me illustrate this subject somewhat further.296 GREEK PHILOSOPHY. Suppose that a man had no pleasure in eating, but that the food he took merely served to keep him in health and strength, without ministering any further than this to his enjoyment. His palate, we suppose, has no sense of taste. His food keeps him alive and in vigour, and that is all. He has no relish, neither has he any repugnance, to any kind of food: all is equally indifferent. Now, in so far as eating is con- cerned, what would this person's end or object or supreme good be ? It would be to keep himself in life, and, moreover, in bodily soundness and activity. That would be his proper end or aim; and what would his duty be ? His duty would consist in eat- ing those meats which conduced most effectually to that end, and to escheW the viands which impaired his powers of life and diminished his activity and strength. In abstaining from the latter, and in pur- suing the former, he would be walking in the path of duty, because he would be in the way of attaining to his proper end, the preservation of his life and the maintenance and perfecting of his health and strength. This individual, his end, and his duty, illustrate in a lower matter the analogous case in the moral world of which I spoke, and which I called man simply. 30. Let us continue our observation of this indivi- dual. Suppose that after a time his food no longer merely keeps him alive and well, but affords a posi- tive and no inconsiderable pleasure to his palate.CYKENAIC, ETC., SCHOOLS. 297 And let us further suppose that some of those dishes which minister most to his enjoyment are exceedingly- prejudicial to his health, while some of those which are rather bitter in the mouth make amends for their repulsiveness by filling him with redundant life, activity, and strength. Now he is in a condition analogous to the position of man considered as susceptible of happiness and misery. But let us ask what change in the end at which he aims, and what change in the duty which guides him in the pursuit, are likely to be brought about by this altered state of things ? The following change, I apprehend, is very likely to ensue. He will be very apt to set up the personal pleasure derived from eating and drinking as his end, instead of the old end, a vigorous and active life: and, aiming at this new end, he will be inclined to devour those meats which contribute most to his enjoyment, without caring how injurious they are to his life and health, while, heedless of its sanitary properties, he will avoid that food which offers no great temptation to his palate. This change in the end will be very apt to bring along with it a change in his conception of duty. Enjoyment being now fixed as his end, he will be very apt to suppose that his duty must consist in attaining to that end at all hazards; and thus he will be led, as I said, to indulge his gluttonous propensities, not keeping his eye on that other end, his health, which the new object of his desire, the new summum bomtm, has thrown into the shade.298 GKEEK PHILOSOPHY. 31. To carry on the illustration. Here, then, we have two ends soliciting this individual,—the old end, life, health, and strength; and the new end, the enjoyment arising from eating and drinking. These two ends are also frequently incompatible with each other. In cases where enjoyment is pursued, health must frequently be sacrificed; while health again is sometimes to be purchased only by the relinquish- ment of pleasure. In these circumstances, the ques- tion is, Which is the end to be pursued ? Is health to be postponed to enjoyment, or is enjoyment to be post- poned to health ? or is there any way in which the two ends can be reconciled ? Three answers may be returned to this question. First, it may be said that health is to be postponed to enjoyment; that enjoy- ment is the chief, and health only the subordinate end. Thik position may illustrate the scheme of such utilitarians or Eudaimonists as set up happiness (with little or no regard to virtue) as the end. Or, secondly, it may be said that enjoyment is to be postponed to health; that health is the chief, and enjoyment only the subordinate end, not properly an end at all. This position may illustrate the scheme of those moralists who set up virtue (with little or no regard to happiness) as the end. Or, thirdly, it may be said that both health and enjoyment may be set up as the chief end; that they admit of con- ciliation, and that rules may be laid down for their extrication when they come into conflict. This posi- tion will illustrate the scheme which, though oftenCYRENAIC, ETC., SCHOOLS. 299 attempted, is still a desideratum in the science of morals. 32. I continue the illustration. I go on to show you what the rules are by which the extrication just referred to may be effected. In the matter of eating and drinking, the first rule is, that life and health and strength are above all things to be at- tended to. These are the paramount considerations ; for these are in fact our very existence as physical beings. This rule is so fundamental and elementary, that it may be said to precede or underlie any gas- tronomical code, any code, that is, that may be formed on the subject of eating and drinking, and the ac- companying pleasures. This rule being understood and taken for granted, the next rule is, that every enjoyment which eating and drinking can procure may be freely indulged in, so far as they do not violate the aforesaid rule. I am considering man at present as a purely physical being, and I say that, health and strength being taken for granted as endowments which must on no account be impaired, pleasure may very well be set up as the great and chief end of eating and drinking, and in so far as duty may be alluded to in connection with so insig- nificant a matter, we may say that it is our duty to get all the enjoyment that we can out of the occupa- tions of the table, subject to the restriction referred to. We thus perceive that, although life and health and strength must never be violated by any excess300 GREEK PHILOSOPHY. in eating or drinking, it is nevertheless quite reason- able to set forth enjoyment as the end, and even as the chief end, which we have in view in taking food. The other end—life, namely, and health—having been laid down as an end to be taken for granted, as an end which must be attained in the very preservation of our existence, our attention will now be very pro- perly fixed on enjoyment as our great and ultimate aim; it will be our duty to apply ourselves to the food for which we have the greatest liking, and to shun that for which we have the greatest loathing; subject, I again say, to the restriction already spoken of, but subject to no other limitation. 33. Still to continue the illustration. We see that the individual, whom we are supposing to have now two ends set before him, has two standards to direct him. He has the old standard, his life, namely, and health and strength. This was his standard when he was supposed to derive no enjoyment from eating and drinking; and he has the new standard, the en- joyment, namely, which after a time we supposed him to acquire. The old standard still retains its force, but so long as it is not violated, so long as life and health are preserved entire, it remains quies- cent, and allows the new standard to prevail. This new standard rules the day, it directs the man, it carries everything before it; and it properly does so, provided the fundamental law of his life and health be preserved inviolate. Thus I conceive the twoCYRENAIC, ETC., SCHOOLS. 301 ends, which we also called standards, are reconciled. In the matter of eating and drinking, health permits enjoyment to put herself forward as the ultimate aim, provided her claims be not compromised, while en- joyment finds her advantage in conciliating health by never being inordinate in her excesses. 34. The application of this somewhat lengthened illustration is this, that just as the preservation of life and health, and the attainment of enjoyment in regard to our body, are two ends quite compatible with each other in the humble and perhaps rather ignoble occupation of eating and drinking; so the maintenance of our rational life, and of the health of the soul, is an end quite consistent with that other, and generally more eagerly pursued end, which goes by the name of happiness. It ^also sometimes hap- pens that the pursuit of what we regard as happiness is not consistent with the rational life and health of the soul, in which case happiness must be foregone in favour of the soul's preservation, just as in analo- gous cases pleasure must be surrendered out of con- sideration for the health of the body. But this being understood, it being understood that man, in the affections which he harbours, and in the actions which he performs, is bound not to do violence to his true and rational nature, this being taken for granted, the other end, his own happiness, namely, and that of others, may now be set full in his view as the proper and only object of his pursuit; and to302 GREEK PHILOSOPHY. the eager pursuit and active diffusion of this happi- ness, he may be exhorted as a duty which cannot be too abundantly fulfilled. 35. We thus see that a complete body of ethics should embrace two codes, two systems of rules, the one of which we may call the fundamental or ante- cedent, or under-ground ethics, as underlying the other; and the other of which we may call the upper or subsequent, or above-ground ethics, as resting on, and modified by the former. The under-ground ethics would inculcate on man the necessity of being what he truly is, namely, a creature of reason and of thought; in short, the necessity of being a man, and of preserving to himself this status. Here the end is virtue, that is, the life and health of the soul, and nothing but this. The above-ground ethics would inculcate on man the necessity of being a happy man. It is not enough for man to be ; he must, moreover, if possible, be happy. The fundamental ethics look merely to his being, i. e.9 his being rational; the upper ethics look principally to his being happy, but they are bound to take care that in all his happiness he does nothing to violate his rationality, the health and virtue of the soul. 36. We now see more clearly than we have yet done the error into which the anti-utilitarians fall. They make the under-ground ethics all in all. They allow no end but virtue. They shut off happinessCYKENAIC, ETC., SCHOOLS. 303 from being the ultimate aim, the proper object of our pursuit. They deal with the one half of morals to the exclusion of the other. On the other hand, the utilitarians fall into the opposite error. They deal only with the upper or above-ground ethics; they overlook the groundwork. They do not see that, before a man can be a happy man, he must first of all be a man, that is, a rational being. In their scheme no provision is made for his being man, but only for his being happy. Happiness, in short, is laid down as the end or chief good of man, without any guarantee being given that this position holds true only in so far as man's rational and fundamental nature is not compromised by its acceptance. Such a guarantee is provided in what we have called the under or fundamental ethics of his condition.PLATO. 1. We now enter on the study of a philosophy which has attracted more notice and excited a deeper in- terest than any other within the whole compass of antiquity—I mean the philosophy of Plato. The best way to attain to a distinct understanding of the general scope and character of this, and indeed of every other philosophy, is by attending to the errors and oversights which it was designed to correct and supplement. Upheld by the ability of the Sophists, sensationalism was the dominant system, as it was the prevailing error, of the time, and accordingly it was against sensationalism and its conclusions that the philosophy of Plato was directed. Sensationalism is supported by the natural sentiments of mankind; it is the scheme which suggests itself most readily to the untutored understanding; it is a product of ordinary thinking. When left to ourselves, we are naturally of opinion that all our knowledge comes to us through the senses, that the senses are the main, indeed the sole means and instruments of cognition, and this opinion is nothing but the doctrine of sensationalism.PLATO. 305 So that the system against which the philosophy of Plato was directed, presented itself in a twofold character : it was a vulgar error, an inadvertency in- cident to our natural and unreflective thinking ; and it was, moreover, an error supported and ratified and reduced to system by the exertions of the Sophis- tical philosophers. And corresponding to the two- fold character of this sensational scheme, the philo- sophy of Plato had a twofold aim : it had to correct sensationalism considered as a product of ordinary thinking, as the creed of the unreflective mind; and also considered as a philosophical and systematised speculation. Platonism, therefore, in its general character, is to be regarded as at once a rectification of the inadvertencies incident to natural or ordinary thinking, and of the aberrations into which the popular philosophy of the day (the system, namely, of the Sophists) had run. To correct these inadver- tencies and errors, it advocated the claims of thought against those of sensation. It showed how impotent the senses are without the aid of the intellect. It put forward its great theory of ideas and idealism in opposition to the current theory of sensations and sensationalism. Such was the general character, both negative and positive, both combative and constructive, of the Platonic philosophy, as gathered from the general consideration of the system of doc- trine to which it stood opposed. 2. This philosophy has exercised a very deep and u306 GREEK PHILOSOPHY. extensive influence on the thoughts and interests of mankind, more so, probably, than any other, either in ancient or in modern times. Aristotle is the only other name that can be put in comparison with that of Plato. The ascendancy of Aristotle may for some centuries have been more despotic, but I am inclined to think that the genius of Plato has from first to last ruled the minds of thinking men with a more living and penetrating sway. Not to speak of his immedi- ate followers, the rise of Neo-platonism, principally in Alexandria, in the centuries immediately subse- quent to the Christian era, attests the depth and extent of Plato's influence. His writings, moreover, were much admired, and closely studied by many of the early Christian fathers. Justin Martyr, Clemens Alexandrinus, Origen, Eusebius, and St Augustin, these founders of the Church regarded Plato as ac- tually inspired, so profoundly were they impressed by the divine character of his instructions; while others were of opinion that he had derived his wisdom from an acquaintance with the Hebrew Scriptures, an opinion, I need scarcely say, which rests on very insufficient evidence. Throughout the dark ages, that is to say, from the sixth to the tenth or eleventh century, an eclipse passed over the light of Plato, as it did over every other light in the firmament of philosophy and literature. From the tenth until the fourteenth century, Aristotle, and not Plato, was in the ascendant. This is the period usually called the middle ages. During its continuance, the only phil-PLATO. 307 osophy in vogue consisted of portions of Aristotle (chiefly his logical treatises), served up in crude Latin translations. At this time the knowledge of the Greek language had died out, or very nearly so, in Europe, and was not recovered until the downfall of Constantinople which was captured by the Turks in 1453. This event had a most auspicious effect on the interests of learning in the West. The downfall of Constantinople dispersed over Europe a multi- tude of learned men who possessed Greek MSS., and who were skilled in the Greek tongue. The study of Greek literature began to be vigorously prosecuted in Europe. Plato attracted a large share of attention. This happened in the fifteenth century of our era; and Italy was the country over which the light of the renovated learning first broke. Here Plato was enthusiastically studied. Marsilius Ficinus trans- lated and commented on his works. Under the auspices of this learned Florentine, Platonism enjoyed a second revival. The enthusiasm spread to other countries, and from that day down to the present the authority of the Platonic writings has never ceased to influence the course of speculation, and to tell even on the general literature of all civilised communities, although it has operated more powerfully and been felt more vividly at one time than it has at another. During the eighteenth century, for example, the in- fluence of Plato had declined. But in the present age the close study of his writings has again revived in our own country, in France, and in Germany.308 GREEK PHILOSOPHY. 3. The philosophy of Plato is so multifarious and unsystematic, that it would be difficult, or rather impossible, to reduce its contents to any very exact classification. It may .be sufficient at present to mention the ordinary scheme which divides it into the three branches, ethics, physics, and dialectics. These are the three sciences which are treated of in the writings of Plato. His ethics are a carrying out and enforcement of the ethical opinions of his great master Socrates. His physics are for the most part crude and fanciful, although marked here and there by very profound and luminous observations. The science of dialectic is supposed to belong more pecu- liarly to Plato, and his philosophy centres in it more essentially than in either of the other two depart- ments ; it therefore behoves us to inquire more par- ticularly into the meaning or purport of the Platonic dialectic. 4. We ask, then, what is dialectic the science of ? The answer is, that it is the science of ideas. Ideas, as all the world knows, play a most important part in the philosophy of Plato. He was indeed the first philosopher who treated expressly of these myste- rious entities, endeavouring to explain their nature, to establish them as the true constituents of the universe, and to displace by their means the sensible phenomena from the hold which they have on the opinions of mankind generally as the only realities which exist. Ideas are the Alpha and Omega in thePLATO. 309 philosophy of Plato. It is not surprising, therefore, that a special name should have been awarded by their expositor to the science which treats of them. That special name is called by him dialectic, a word which, looking to its derivation, has no connection with ideas, but which is derived from $ia\eyecr0ai, to discourse or discuss in the way of dialogue; so that the name of the science seems to have been sug- gested by the conversational way in which the ideas were discussed, rather than by anything connected with the nature of the ideas themselves; or the word dialectic may signify that silent dialogue which the mind carries on within itself whenever it is engaged in meditation. We shall have occasion hereafter to go more deeply into this science of ideas. Mean- while I am dealing with little more than the nomen- clature of the Platonic speculations. 5. I may here mention some of the principal Dia- logues which deal respectively with the three sciences, dialectic, ethics, and physics. Dialectic shows itself in the Meno, the Theaetetus, the Sophista, the Par- menides, the Philebus, the Phaedrus, the Phaedo, and the Eepublic. Ethics are treated of principally in the Philebus and the Eepublic, to which may be added the Euthyphro. The physics are contained for the most part in the Timaeus. Erom this enumera- tion you will perceive that ethics and dialectic are sometimes treated of in the same Dialogue. The classification, however, is, I think, sufficiently accu-310 GREEK PHILOSOPHY. rate to let you know generally which of Plato's Dia- logues are dialectical, which ethical, and which physi- cal. I have mentioned only the principal Dialogues on the three branches of science. 6. Much controversy has prevailed in regard to the genuineness of the Platonic writings. Some in- quirers, actuated by a spirit of extreme scepticism, have admitted as genuine a very meagre proportion of his Dialogues, while others, influenced by a con- trary spirit of extreme credulity, have accepted as his everything which has come down to us in his name. The truth seems to be, that while several of the compositions which are incorporated with all the editions of Plato's works must be pronounced spuri- ous, all the more important Dialogues are genuine. The following is a list of the writings which have been generally regarded as spurious by those who are most competent to judge on this question. The Platonic Epistles (although these, I believe, are de- fended as genuine by so high an authority as Mr Grote*). The Upinomis, the second Alcibiades, the Theages, Anterastce, or the rivals in love, Hipparchus, Minos, and ClitophonA With the exception of these few and comparatively insignificant pieces, the entire body of the Platonic writings may be relied on as genuine, as the authentic utterances of the great dis- ciple of Socrates. They are compositions which, whether we look to their style or their substance, far * Thompson on Butler's 'Ancient Phil.' ii. 16. +Ib. 48.PLATO. 311 surpassed in beauty and in depth everything which had preceded them in philosophy, and they have been followed by very few works which will bear any comparison with their excellence. In the Platonic writings the form of dialogue was used probably for the first time as the vehicle of philosophical thought, and it started at once into perfection. In grace and ease, in poetical beauty and dramatic spirit, these Dialogues have never been equalled. In modern times they have frequently been imitated; and in our own country, the two philosophers who have imitated them most successfully, although they fall far short of their great original, are Berkeley and Shaftesbury. 7. The dialectic is the first part of the Platonic philosophy which must engage our attention. Dia- lectic, as I have said, is the science of ideas. We shall therefore have to inquire and ascertain as clearly as we can what ideas are in the Platonic sense of the term. This is an inquiry in which, from first to last, much labour has been expended. I am of opinion that, although the exertions of those who have explored this field are far from having been fruitless, much research and reflection are still re- quired in order to set forth the nature of ideas in a perfectly distinct light, and in order to appreciate, at its true value, the Platonic theory which deals with them. But, before entering on this research, I shall call your attention to a few preliminaries which come before us at the threshold.312 GREEK PHILOSOPHY. 8. One point for preliminary consideration is this: By ideas, two things may be meant. Ideas may either be a name for thought or knowledge in its simplest, lowest, easiest, or most elementary form; in that form in which knowledge is possessed by all human beings, even the most uninstructed; or ideas may be a name for that higher and more complex kind of knowledge called science, which is the pos- session of comparatively few. In which of these acceptations, then, does Plato employ the term ? Do his ideas mean knowledge of the simplest character, knowledge which no man can open his eyes with- out receiving ? or do they mean knowledge of a loftier order, and which it requires some exertion to attain to ? 9. The true answer, I believe, is, that by ideas Plato intends to designate both kinds of knowledge, the lower and the higher. But as he employs the word more frequently, and with greater emphasis, in reference to our higher than to our lower know- ledge, one is apt to think that this theory of ideas is rather a theory of science in its loftiest pretensions, than a theory of thought and knowledge simply, and in their humblest and commonest manifestations. The consequence has been, that his expositors have usually expounded the ideas as more peculiarly the property of the scientific mind, and as acquisitions which it required a large amount of philosophic culture to get possession of.PLATO. 313 10. This explanation of the Platonic ideas, though not positively false, is exceedingly misleading. It is not positively false, because ideas are in truth the truth, the light of all science. But it is exceedingly misleading, because it conveys the impression that they are not equally essential to our simplest acts of thought and knowledge, and that there may be a lower species of knowledge into which ideas do not enter. The truth, however, is, that ideas are just as essential to our ordinary and most familiar cogni- tions, as they are to our most recondite and elaborate sciences, and it is in their relation to common think- ing that they ought to be studied much more than in their relation to scientific cognition. We shall perceive their necessity, we shall understand them as part and parcel of ourselves, much more clearly when we view them as conditions without which no thought or knowledge of any kind is possible, than we should do if we viewed them merely as certain requisites which contributed to the construction of science. Plato speaks of them, as I have said, very frequently under the latter relation. But there is suf- ficient evidence that he regarded them under the for- mer as well, under that relation which I venture to think is much the more important of the two. Leaving his expositors, then, to interpret the ideas as essential to the constitution of science, I shall explain them principally, if not exclusively, as necessary to the ex- istence of our simplest knowledge, and as that without which no thinking of any kind could take place.314 GREEK PHILOSOPHY. 11. I have said that Plato dwells principally on ideas in their higher function as instrumental in the construction of science, and that he seems to insist with less emphasis on the necessity with which they are present in all, even in our humblest cognitions. I have also said that the importance of ideas, and the value of the theory which expounds them, are much more conspicuous when we look at them in the latter, than when we look at them in the former character. When we regard them as the light of all thought and all knowledge, the theory is admirable (as I hope to show you); when we regard them merely as the light of science, and as the property merely of scientific men, the theory is shorn of its significance. The following remark may perhaps help to clear up or remove the ambiguity which Plato has himself thrown around the theory. Every human being in the simplest act of knowledge makes use of ideas; ideas are present to his mind; but he is not cognisant of their nature and character; he is not aware even of their existence. They are in possession of him, rather than he of them; he is un- conscious of their necessary and unfailing presence. To make him conscious of this presence, to make him aware of the necessity and the nature of ideas, a special and difficult science is required, the science of Dialectic. Now, in broaching his theory of ideas, I conceive that what Plato means to inculcate is not that it is difficult for the mind to get hold of ideas, or that any science is required to put us in possessionPLATO. 315 of them, or that they are the property only of the favoured few who have been highly gifted and highly educated. That, I say, is not what he means to incul- cate, but rather this, that the mind being already in possession of ideas, it is the hardest of all tasks, and requires the most persevering meditation for the mind to make itself cognisant of these possessions, and to understand the nature of these ideas. From the manner, however, in which he frequently ex- presses himself, one might readily mistake his drift, and might suppose that he was pressing on his readers the necessity of their acquiring ideas, if they wished to be men of science or philosophers; where- as the truth is that he is merely pressing on them the necessity of their acquiring a knowledge of the ideas which they already possess, and which are at once the enlightening principle of their own minds, and the staple of the universe. The difference be- tween the mind which is informed by dialectic, and the mind which is not so informed, is simply this: that the ordinary or uninformed mind has ideas, while the dialectic mind knows that it has them, and understands what they are. The other interpreta- tion, that usually adopted by the Platonic expositors, seems rather to be this: that the ordinary mind has no ideas at all, but is informed by a lower species of knowledge, into which ideas do not enter, while the dialectic mind alone both has ideas and is cognisant of their presence and nature. This interpretation is, I conceive, quite wrong.316 GREEK PHILOSOPHY. 12. Another preliminary point requiring some notice, is the consideration of those sciences which draw away the mind from the contemplation of sen- sible objects, and turn it to the study of universal truth. Among these are to be reckoned arithmetic and geometry; sciences which, according to Plato, are the best preparation by which the mind can be trained to the higher study of dialectic. Speaking of geometry, he says (the words are put into the mouth of Socrates): "You also know," says Socrates, "that the geometricians summon to their aid visi- ble forms and discourse about them, though their thoughts are busy, not with these forms, but with their originals, and though they discourse not with a view to the particular square and diameter which they draw, but with a view to the absolute square and the absolute diameter, and so on. For while they employ by way of images those figures and diagrams aforesaid (which again have their shadows and images in water), they are really endeavouring to behold those things * which a person can only see with the eye of thought," that is to say, not this or that circle, or this or that square, but square and circle viewed universally, which they cannot be by sense or imagination, but only by the intellect (htavoia). Again, speaking of geometry, the Platonic Socrates says: " It is indeed no easy matter to believe that, in the midst of these mathematical studies, an organ * Not "abstractions," as wrongly rendered by the Cambridge translation.—Rep. vi. 510.PLATO. 317 of our soul is being purged from the blindness, and quickened from the deadness, occasioned by other pursuits—an organ whose preservation is of more importance than a thousand eyes, because only by it can truth be seen. Consequently, those who think with us will bestow unqualified approbation on these studies." * These extracts may be sufficient to show the importance which Plato attached to mathemati- cal science as a training of the mind for the study and reception of the purer and loftier truth revealed to it by dialectic. The words, however, which Plato is said to have inscribed over the gate of the aca- demy where his discussions were held, " Let no one who is not a geometrician enter these walls "—fjuySeU ayeay/jLerprjTos elatrco, are erroneously attributed to the philosopher, although they are quite in accordance with the tone and spirit of his instructions. 13. The following passage from the 7th Book of the Bepublic, contains the celebrated similitude in which Plato allegorises the conversion of the mind from the world of sense to the world of ideas. I read it to you as preparatory to our discussion of his theory of ideas, t " Suppose," says Socrates, " a set of men in a sub- terraneous cavern, which opens to the day by a long straight wide passage, and that they have been kept in this cavern from childhood, fettered so that they * Rep. vii. 527. t Rep. vii. 514; Wliewell's Translation, iii. 297.318 GREEK PHILOSOPHY. cannot turn even their necks, but with their heads fixed so that they can look only towards the lower end of the cave. Suppose, further, that there is a great fire lit opposite to the mouth of the cavern (so as to throw the shadows of objects on the lower end of the cave), and that there is a road which runs past the cavern between the fire and the captives. Suppose, too, that along this road runs a low wall, like the partition over which puppet-showmen ex- hibit their figures. And now suppose that along this wall, and so as to be shown above it, pass men and other figures, some silent, some speaking. You think this is a strange imagination. Yet these captives exactly represent the condition of us men who see nothing but the shadows of realities. And these captives, in talking with one, would give names to the shadows as if they were realities. And if, further, this prison-house had an echo opposite to it, so that when the passers-by spoke the sound was reflected (from the same wall on which the shadows were seen), they would, of course, think that the shadows spoke. And, in short, in every way they would be led to think there were no realities except these shadows. "Now consider how these captives might be freed from these illusions. If one of them were loosed from his bonds, and made to turn round and to walk towards the light and look at it; at first he would be pained and dazzled by the glare, and un- able to see clearly. He would be perplexed if hePLATO. 319 were told that what he saw before were nonentities, and that now, being brought nearer to the reality and turned towards it, he saw better than before; and even if any of the passers-by were pointed out to him and made to answer questions, and to say what he is, he would still think that what he saw before was more true than what was shown to him now. He would shun the excessive light, and turn away to that which he could see, and think it more visible than the objects which had been shown him. " But if he were dragged to the light, up the steep and rough passage which opens to the cave, and fairly brought out into the light of the sun, he would be still more pained and more angry, and be at first so blinded that he would not be able to see real objects. It would require time and use to en- able him to see things in daylight. At first he would be able to see shadows, then the reflected images of objects, and then objects themselves; and afterwards he might be able to look at the heavens by night, and see the heavenly bodies, the stars and the moon; and finally be able to look at the sun; not merely at a reflection of him in water, but at the sun himself in his own place. And then he might be led to rea- son about the sun, and see that he regulates seasons and years, and governs everything in this visible world, and is in a certain sense the cause of all the things which they in their captivity saw.320 GREEK PHILOSOPHY. "And then when he recollected his first abode, and the illusions of that place, and of his fellow- captives, he would naturally congratulate himself upon the change, and pity those he had left there. And if there were among them any honours and rewards given to him who was most sharp-sighted in scanning the passing shadows, and readiest in recol- lecting which of them habitually went before, and which after, and which together, and who hence was most skilful in predicting what could happen in future, he would not be likely to covet these honours and rewards. He would rather say with the shade of Achilles in Homer, that it is better to be a day- labourer in the region of life and day, than the greatest monarch in the realm of shadows. He would rather suffer anything than live as he did before. " And consider this further. If such a one should redescend into the cavern, and resume his former seat, his eyes would be purblind, coming out of sunshine into darkness. And while his eyes are still dark, and before they have recovered their power, if he had to discuss those shadows with those who had always remained there captive (a state of things which might last a considerable time), he would be utterly laughed at, and they would say that his eyesight was ruined, and that it was not worth anybody's while to go up out of the cave. And if any one tried to set them at liberty, and toPLATO. 321 lead them to the light, they would, if they could get him into their power, kill him. " Now this image, my dear Glaucon, is to be ap- plied to the case we were speaking of before. We must liken the visible world to the dark cavern, and the fire which makes objects visible to the sun. The ascent upwards, and the vision of the objects there, is the advance of the mind into the intelligible world; at least such is my faith and hope, and of these you wished me to give an account. God knows if my faith is well founded. And, according to my view, the idea of the Supreme Good is seen last of all, and with the greatest difficulty; and when seen, is apprehended as the cause of all that is right and excellent. This idea produces in the visible world light, and the sun the cause of light; in the intellectual world it is the cause (source) of truth, and of the intuition of truth. And this idea he who is to act wisely either in private or in public matters must get possession of. "And now, as you agree with me in this view, you will agree with me further, that it is not to be wondered at that those who have advanced into that higher region are not willing to be involved in the affairs of men; their souls wish to dwell for ever in that upper region. Nor is it wonderful if any one coming down from divine contemplations to the wretched concerns of men blunders and is laughed at; while he is still purblind, and before his eyes x322 GREEK PHILOSOPHY. are accustomed to the surrounding darkness, he is compelled, it may be, to fight in courts of justice, or elsewhere, the battle, not about justice, but about the shadows of justice, or the images which make the shadows; he is compelled to wrangle about the way in which these shadows are apprehended by those who never had a view of justice herself. If any one has any sense, he will recollect that there are two kinds of confused vision arising from two opposite sources; that which happens when men go out of light into darkness, and that which happens when they go out of darkness into light; and the case is exactly the same with the mind. And when such a one sees a mind confused and unable to dis- cern anything clearly, he will not laugh without consideration; he will consider whether in that case the mind is darkened by coming out of a clearer light into unaccustomed darkness, or, going from ignorance to clearer knowledge, is struck with con- fusion by the brightened splendour. And in the latter case he would think that mind happy in its constitution and condition, and pity the other; and if he were disposed to laugh at it, his laughter would be far less in a temper of ridicule than his laughter at him who comes from above below, from the light into the dark." 14. In the following quotation from the 10th Book of the Republic, the ideas are explained and illustrated by Plato himself. Here he representsPLATO. 323 them as the models or archetypes according to which the Deity fabricates all things. The speakers are discoursing on the subject of imitation.* "What is imitation? We are accustomed to say that all the things which have the same name belong to one kind. Take anything for an example. There are many chairs and many tables; but there is only one idea of a chair and one idea of a table. And the artificer who makes each of these pieces of furniture looks to his idea of a chair or a table, and so makes the chairs and the tables which we use. The man does not make the idea, he only copies it. " But now, what do you call an artificer who makes all the things which any of the (kinds of) handi- craftsmen make, and not only all articles of furniture, but all the plants which grow out of the earth, all animals, and himself; and moreover the earth, the heavens, the gods, and all that is in heaven, and all that is in Hades under the earth ? You think this must be a wonderful artist ? There may be a work- man who can make all these things in a certain sense, and in a certain sense cannot. You yourself might make all these things in a certain sense; for instance, if you take a looking-glass, and turn it on all sides, you may forthwith make the sun and the sky, and the earth, and yourself, and animals, and plants, and articles of furniture, such as we have been speaking of. You say that you make their * Rep. X. 596 ; Whewell, iii. 327.324 GREEK PHILOSOPHY. appearances only, not the things themselves. That is just the point I wish to come to. " And so the painter can make things in the same way; he does not make the real thing. He makes an apparent table, not a real table. " But the carpenter—does he make a real table ? We have just agreed that he does not make that which is essentially a table, but only a kind of table. He does not make the thing that is, but only some- thing that is like it. If any one says that the thing produced by any handicraftsman really is, he makes a mistake. The things which are thus produced are dim shadows of the truth. "Now, let us see what is meant by imitation. There are, for instance, three kinds of tables. The first the essential ideal one, which God himself makes; then the one which the carpenter makes; and then the one which the painter makes. The painter, the carpenter, God; these are the three makers of the three kinds of tables. The one made by God is single, unique; there are not and will not be more than one. There cannot be two or more. If He had made two or more ideas of kinds of tables there would be a third—the idea of table in general, and this would be the real idea of table. And thus God is the real author of the real table, but not of any particular table, so as to be a table-maker. " But the carpenter also makes a table; what is he ? He is a table-maker. "And the painter; does he made a table? No;PLATO. 325 he imitates a table. And so the man who makes the third copy of the original is an imitator " 15. I shall conclude the preliminaries and prepara- tions for the closer study of the Platonic dialectic by reading you an extract from the lectures of the late Professor Butler of Dublin, in which he explains his conception of the Platonic theory of ideas. He ex- plains ideas as the laws according to which God regulates the universe; a view not erroneous, but only rather vague, and conveying the impression that ideas do not enter into all our knowledge, but are the animating principle of our higher cogni- tions only. "You can now enter easily into the aim of the theory of Ideas. That man's soul is made to contain not merely a consistent scheme of its own notions, but a direct apprehension of real and eternal laws beyond it, is not too absurd to be maintained. That these real and eternal laws are things intelligible, and not things sensible, is not very extravagant either. That these laws, impressed upon creation by its Creator, and apprehended by man, are something different equally from the Creator and from man, and that the whole mass of them may be fairly termed the world of things purely intelligible, is surely allow- able. Nay, further, that there are qualities in the supreme and ultimate Cause of all, which are mani- fested in His creation, and not merely manifested, but, in a manner—after being brought out of His super-326 GREEK PHILOSOPHY. essential nature into the stage of being below Him, but next to Him—are then, by the causative act of crea- tion, deposited in things, differencing them one from the other, so that the things participate of them (/xer- kyovcrC), communicate with them (/coivcovovcrt); this likewise seems to present no incredible account of the relation of the world to its Author. That the intel- ligence of man, excited to reflection by the impres- sions of these objects, thus (though themselves transi- tory) participant of a divine quality, should rise to higher conceptions of the perfections thus faintly exhibited; and inasmuch as these perfections are unquestionably real existences, and known to be such in the very act of contemplation—that this should be regarded as a direct intellectual appercep- tion of them, a union of the reason with the ideas in that sphere of being which is common to both— this is certainly no preposterous notion in substance, and by those who deeply study it, will perhaps be deemed no unwarrantable form of phrase. Finally, that the reason, in proportion as it learns to contem- plate the perfect and eternal, desires the enjoyment of such contemplations in a more consummate de- gree, and cannot be fully satisfied except in the per- fect fruition of the perfect itself, this seems not to contradict any received principle of psychology, or any known law of human nature. Yet these sup- positions, taken together, constitute the famous ' Theory of Ideas;' and thus stated, may surely be pronounced to form no very appropriate object forPLATO. 327 the contempt of even the most accomplished of our modern 'physiologists of mind/"—(Butler's 'Lec- tures on Philosophy,' vol. ii. pp. 117-18-19.) 16. Before entering on the exposition of Plato's dialectic or theory of ideas, I thought it right to call your attention to certain preliminary considera- tions. These were the settlement of the question, Are the Platonic ideas the necessary constituents of all knowledge, or only of scientific knowledge ? My conclusion is that they are, according to Plato, the necessary constituents of all knowledge, although it must be confessed that he has left this point some- what ambiguous, and has thereby misled his exposi- tors, who frequently regard the ideas as belonging more properly to scientific than to ordinary cogni- tion. The true interpretation is, that while all minds have ideas, the instructed mind both has and knows that it has them. I then mentioned the sciences which, in the opinion of Plato, were the best prepara- tion for dialectic; these were arithmetic and the mathematical sciences, particularly geometry. These, when rightly cultivated, lead the mind to look at truth, not in the particular, but in the universal, and thus furnish a proper training for the higher study of ideas. As a further introduction to dialectic, and in order to familiarise you with the main object of Plato's philosophy, which is to turn the mind from the comparative unrealities of sense to the realities of reason, which ideas are, I read to you his cele-328 GREEK PHILOSOPHY. brated similitude of the Cave, in which this conver- sion is allegorised. I then read to you an extract from Plato, the purport of which was to show that, just as an existing sensible object has a higher degree of reality than a mere painting of it, so the divine and eternal idea of that object has a higher degree of reality than the object itself, and that, just as we may very well consider the painting unreal when com- pared with the object, so we may very properly re- gard the object as unreal when compared with its eternal idea. And, finally, my object in reading to you a few extracts from Professor Butler was to make you acquainted with the somewhat vague and un- satisfactory interpretation of the Platonic ideas which is generally current. 17. Having disposed of these introductory matters, I now enter on the dialectic of Plato. And as this science is the science of ideas, we have first of all to consider what ideas are in themselves. We must try to fathom their nature as much by our own reflec- tions as by means of the light which Plato has con- tributed to the research. It is not so much by read- ing Plato as by studying our own minds that we can find out what ideas are, and perceive the significance of the theory which expounds them. It is, as I formerly said, only by verifying in our own conscious- ness the discoveries of antecedent philosophers that we can hope rightly to understand their doctrines or appreciate the value and importance of their specu-PLATO. 329 lations. We must endeavour to apply this rule to the present case. 18. In dealing with the philosophy of Socrates, I touched on several truths which carry us a consider- able way, I think, towards a right understanding of the Platonic ideas; these were the universality of ideas as contrasted with the particularity of sensa- tions, the activity and freedom of the mind, its emancipation from the bondage of sensation, evinced in its rising into the region of ideas even in its lowest and most ordinary cognitions. I am not sure that I have very much to add to the explanation of ideas there given, but I shall endeavour to present it in a somewhat new light, and under a somewhat different point of view. 19. Let me dwell, first of all, on the necessity of ideas, the necessary truth which is their main char- acteristic. You have all heard of necessary truth, and understand, I daresay, something of its nature. Necessary truth is truth which the mind cannot help acquiescing in; it is truth for all minds, and not truth merely for this or that particular kind or order of minds. Such truths are the axioms of geometry, and indeed all mathematical truth. Necessary truths are those of which the opposites are absurd, incon- ceivable, contradictory. In explaining, then, the necessity of ideas, what I wish to show you is, that ideas are essential, are absolutely indispensable to330 GREEK PHILOSOPHY. the operations of thought, and to the very existence of intelligence. No thinking can possibly go on with- out them; to suppose that it can is to suppose an absurdity and a contradiction. The necessity that characterises ideas is of the highest and most strin- gent order. And, accordingly, the theory which ex- pounds them must be accepted, not as a doctrine which may possibly be erroneous, but as a system of truth which cannot possibly be mistaken. In its expression, this theory may probably be defective; indeed it may be impossible to express it in terms which are not more or less imperfect, but in itself, and substantially, it cannot be fallacious. 20. The necessity, the necessary truth, which is the main characteristic of ideas, and which marks this theory, will become conspicuous if we make the attempt to carry on thinking without the instrumen- tality of ideas, that is, of universals. This attempt will show how essential ideas are to the operations of thought, and how impossible it is for thought to be performed without them. Let us, then, make the attempt; let us try whether we can think without anything more than sensation coming into play. I have a sensation of light, and a bright object, say a gas-lamp, is before my eyes. Now, so long as I am merely in a state of feeling, I am tied down to this particular sensation; my sensation does not overstep one hair's-breadth the sensation which I experience. The sensation is exactly that sensation, and nothingPLATO. 331 else, nothing either more or less. The problem is to make me not only feel but think this sensation, and to think it without getting out of sensation, i.e., without getting into the region of ideas; for I wish to show that it is impossible for me to do this, and thus by a reductio ad absurdum to prove the neces- sity of ideas. I think the sensation then, the sensa- tion of light and the bright object before me. Now what has taken place here different from mere feel- ing ? This has taken place: in thinking the sensa- tion, I think that it is, and that the bright object is. Perhaps I think of more than this, but this, at least, is what I think. I repeat it: I think that the sen- sation is, and that the object is. In thinking them at all, I must think that they are. But you will very likely say, What is there here more than mere feeling ? When a man feels a pain, does he not feel that it is ? I answer that it may do very well in ordinary language, to say of a man in pain that he feels that it is, but such a statement (viewed philoso- phically) is exceedingly incorrect. The precise state- ment is this, that the man merely feels the pain; he thinks or knows that it is (you will understand this more clearly immediately). I again affirm that in thinking the sensation (as an act distinct from merely feeling it), I think that it is. That is my first step in thinking it; that is the least which I do. We have now to ask what is involved in think- ing that the sensation is. There is this involved in it, that I transcend or go beyond the sensation, and332 GREEK PHILOSOPHY. bring down a category or universal upon it, the cate- gory or universal called Being. But Being is an idea. Being is not identical or commensurate with my sensation, it embraces infinitely more. Being is not my sensation, but something different from it; and being something different from sensation, it pro- perly obtains a different name; it is called an idea. We thus see that in the simplest and earliest opera- tion of thinking, we are forced, whether we will or no, into the region of ideas, and that thinking is im- possible without them. Thinking is, in fact, nothing else than the application of ideas or universals to the sensible phenomena of the universe. And the theory which declares this to be the case (as Plato's theory does) is not so much a theory as a fact; a fact which it is impossible to dispute or deny, without falling into the grossest absurdities and contradictions. 21. To this argument proving the necessity of ideas, the objection may perhaps be raised that it is a mere truism, equivalent to the assertion that it is impossible to think without having thoughts, a pro- position which no one would ever dream of denying, but which does not advance us far in our pursuit of truth. I answer that the argument does amount to that proposition, but it also amounts to a great deal more. It not only shows that we cannot think with- out having thoughts or ideas, but it moreover ex- plains what ideas are; it sets them forth as univer- sals, and thus essentially distinguishes them fromPLATO. 333 sensations, which are of necessity particular. A man certainly learns nothing from being told that he can- not think without ideas, but he may learn something, or rather (to take the Socratic view of education) he may teach himself something from being told that he cannot think without passing from the particular to the universal. What was proved in the preced- ing paragraph was not merely that a man cannot think without having ideas, but that he cannot think without going beyond the particular and passing into the universal, a profound truth. The one of these statements is a mere truism, but the other, I venture to maintain, is one of the profoundest truths that ever addressed itself to the capacities of think- ing men, and summoned them to put forth their utmost capacities to unravel it. Let us endeavour to get somewhat deeper into the purport of this truth— this truth which is expressed in the proposition, that to think is to pass from the singular or particular to the idea or the universal. 22. It is an accredited maxim in the Lockian or sensational schools of philosophy, that we can think only of that of which we have had experience. And this dogma seems to recommend itself at once to the common sense of mankind, for where, it may be asked, can we get the materials of our thinking except from experience, either external or internal ? Now, irresistible as this dogma appears, I venture to set up in opposition to it this counter-proposition,334 GREEK PHILOSOPHY. that it is impossible for us to think only of that of which we have had experience. This is merely another form of the assertion just made, that all thinking is necessarily a passing from the singular to the universal. I shall endeavour, by means of a very simple illustration, to explicate what this pro- position involves. I wish to show you more parti- cularly what is meant by the universality of ideas. A man sees an object for the first time, let us say a chair. Now so long as he merely sees it, his state is purely sensational, he is limited to the particular, he is shut up in the region of the singular. Let us now suppose that he thinks it. "What is the exact nature of the mental operation here performed ? I conceive it to be this: In thinking the chair, the man views it as an instance of which there may be, or are, other instances. Suppose that the man had never seen anything except this chair, in thinking it, he would still think it as something; that is (even although he had no language to express his thoughts), he would nevertheless place it under the category of thing; in other words, he would think other pos- sible chairs (and other possible things) as well. If he thinks the chair, I affirm that he cannot think merely it, but must think something more. Here then is a marvellous consideration: The man has had experience only of one chair, of one thing; but in thinking it, he has thought other chairs, other things; in short, he has thought something of which he has had no experience. This is an astonishingPLATO. 335 position, and looks very paradoxical; but it is never- theless the fact, and we must accept it as we find it. It utterly overthrows the Lockian school of philoso- phy, for it proves that there is something in the mind which neither entered by the way of outward experience, nor was generated by internal experience, or by what Locke calls reflection on our own mental operations. That on the presentation of one object I should be able, indeed, that I should be necessitated, to think of another object as well, this is a fact which discredits altogether the philosophy of sensational experience. If this philosophy would make good its ground, it must prove that we cannot think of more than we have actually experienced, and that if, in the course of our experience, we had only seen twelve men, it would be impossible for us to think of a thirteenth; but such a proof is manifestly impossible, and such a conclusion would be absurd. My posi- tion is, that supposing we had never seen more than one man, we must, in thinking him, view him as an instance, and viewing him thus, we must virtually think an indefinite number of men. This is so far an explanation of what is meant by all thought being a passing from the singular to the universal. 23. In attempting to expound the nature of ideas, with the special view of throwing light on what Plato understood by them, I touched, in the conclud- ing paragraphs of my last lecture, on two of their chief characteristics; these were, their necessity and336 GREEK PHILOSOPHY. their universality. Ideas are necessary, because no thinking can take place without them. They are universal, inasmuch as they are completely divested of the particularity which characterises all the phe- nomena of mere sensation. To grasp the nature of this universality is not easy. Perhaps the best means by which this end may be compassed is by contrasting it with the particular. It is not difficult to understand that a sensation, a phenomenon of sense, is never more than the particular phenomenon which it is. As such, that is, in its strict particu- larity, it is absolutely unthinkable. In the very act of being thought something more than it emerges, and this something more cannot be again the parti- cular, for in that case something more would again emerge, and so on for ever. For example, suppose that in thinking a particular object, the additional something which I thought of were one other parti- cular object or ten other particular objects; in that case I maintain that no thinking would have taken place, for I would still be confined to the particular; ten particulars, per se, cannot be thought of any more than one particular can be thought of. When ten particulars, or ten hundred particulars, are thought of, there always emerges in thought an additional some- thing, which is the possibility of other particulars to an indefinite extent. In the operation of thinking, any given number of particulars are always reduced to so many instances, and the indefinite outstanding something which they are instances of is a universal.PLATO. 337 There is thus a contrast in thought between two ele- ments, the universal and the particular, and both of these are essential, I conceive, to the process of think- ing. The particular element is usually a sensation, or sensible thing. The universal element is called by Plato an idea. 24. We may perhaps get still further light on the nature of ideas if we view the matter in this way. Every object that we behold is an instance, that is, it is looked upon as not the only case of the kind ; other instances are either actual or possible. But all instances must be instances of something. What is that something? That something is an idea. We require a different term from the word instance to mark that of which the instance is, and for this pur- pose we employ the term idea. The particular thing before us (suppose it is a tree) is an instance; an instance of what ? It is an instance of a tree; but is the tree before us of which this is an instance ? Certainly it is not. The particular tree is before us; but that of which it is an instance is not before us, not before us as a particular, is not visible to our sense of sight, although present to the mind as an idea or universal. We thus make a distinction be- tween an instance and that of which it is an instance. In fact, here again we find the two elements which are essential to all thought, the particular and the universal. The terms by which we have just desig- nated them are, the instance, and that of which the Y338 GREEK PHILOSOPHY. instance is. A thing cannot be an instance without being an instance of something; in so far as it is an instance, it is particular. The something of which it is an instance is a universal, an idea. Plato calls it also irapaheiyiia. 25. I must put you on your guard against suppos- ing that it is possible for you to form any sort of representation of the idea or universal, or paradeigma. This cannot be done. The idea or universal cannot by any possibility be pictured in the imagination, for this would at once reduce it to the particular; this would destroy it as an idea, and convert it into an instance, which instance being of course an in- stance of something, would again require to be sup- plemented in thought by that of which it was an instance, namely, by an idea or universal. Much confusion is caused when we attempt to construe the idea to our mind as any sort of imaginary object. "We must be satisfied, therefore, with thinking the idea or universal as a fact of intellect which is neces- sary as a foil or offset or complement to the other element of our cognition, the particular instance, namely; but which cannot be apprehended either by the senses or by the imagination, which derives all its data from the senses, and copies their impres- sions. This inability to form any sort of picture or representation of an idea does not proceed from any imperfection or limitation of our faculties, but is a quality inherent in the very nature of intelligence.PLATO. 339 A contradiction is involved in the supposition that an idea or universal can become the object either of sense or of the imagination. An idea is thus diamet- rically opposed to an image, although in ordinary, and even in philosophical language, the two terms are frequently confounded, and regarded as synony- mous with each other. 26. I have hitherto spoken of necessity and uni- versality as two main characteristics of our ideas. I have now to remark that ideas are essential to the unity of our cognitions. They are not merely inde- finite possibilities which no given number of in- stances can exhaust, but they are principles by which the variety and multifariousness of our sensible impressions are reduced to unity and order. Resem- blance, for example, is the great principle of arrange- ment and classification. We class things together under genera and species according to their resem- blance. But resemblance does not come to us through the senses, or by the way of sensation; it is no sensible impression,, it is a pure idea. When two trees are before us, we see the trees, but we do not see their resemblance. This is a thought, not an object of sense. Eesemblance is a relation, and, as such, it cannot be seen, or touched, or apprehended by any of the senses. These apprehend only the things. Their relations of resemblance and difference are ap- prehended only by the intellect. If the mind had no idea of resemblance, and no idea of difference, if we340 GREEK PHILOSOPHY. had not these principles to guide us in the arrange- ment and classification of our knowledge, it is mani- fest that our cognitions would have no unity, order, or coherence; our mental state would be no better than a chaotic dream. So essential are ideas to the existence of knowledge, so impotent are sensations, without ideas, to instruct us even in the most ele- mentary truths. 27. This may further serve to illustrate a subject on which Plato has bestowed a good deal of elaborate treatment, the conversion, namely, of the human soul from ignorance to true knowledge. The ignorant and unconverted soul supposes that its knowledge of sensible objects is due to the impressions which it receives; the converted soul is aware that this know- ledge is due, not to these impressions, but to the ideas of resemblance and difference (and some other ideas) by which these impressions are accompanied, but with which they are not by any means identical; in fact, that our whole knowledge of outward things is based entirely upon ideas, and is effected solely by their mediation. 28. From what has been already said in regard to the distinction and opposition between the particu- larity of sensation, and the universality of intellect, it is obvious that ideas cannot be the products of our sensible experience. Hence they must be re- ferred to some other origin; they must be pronouncedPLATO. 341 innate; innate inasmuch as we do not derive them from without, but from some source which is either the mind itself, or intimately allied to the mind. We find, accordingly, that Plato held ideas to be innate; that they were not imparted to the mind from without, although they were elicited into con- sciousness on the occasion of some outward impres- sion. Plato thus stands forth in the history of philosophy as the first and principal philosopher by whom the doctrine of innate ideas was expressly advocated. He followed Socrates in the opinion that the seeds of all rational knowledge pre-existed in the mind, that they might be drawn forth into full growth and development from within, but could not be imparted to us from without. He held, more- over, with Socrates, that the true art of education consisted in educing from the pupil's own mind its own native treasures, by stimulating his reflective capacities. The Sophists, on the contrary, regarded the mind as a tabula rasa, on which no original characters were inscribed; and their boast was, that they could communicate to the minds of their pupils any amount or any kind of knowledge that was required. 29. That the doctrine of innate ideas is true in some sense, and to some extent, is undeniable; and therefore Locke's repudiation of the docrine, as one which could not be accepted on any terms, must be set aside as shortsighted and injudicious. It is still,342 GREEK PHILOSOPHY. however, a question in what sense and to what extent is this doctrine to be accepted. It may be asked, for example, in what sense are the conceptions expressed by the word animal, man, tree, to be regarded as innate? I answer, that these conceptions are not innate, if we suppose them to denote, as most people do, some faint or vague representation of animal, man, or tree; nothing which is representable as an object is in any degree innate, and therefore these conceptions, if they are innate, must not express anything which can be represented as an object. What, then, do these terms denote? They denote the fact that, on the occasion of an animal, a man, or a tree being presented to the mind, the mind thinks not merely of the one man, the one animal, or the one tree, but of something wider; in short, of a class, which class is to be construed to the mind not as an object, but as a fact or law; a fact or law by means of which unity is given to a number of our resembling impressions. Viewed in this way, the conception man may be said, with perfect truth, to be innate. When a man is placed before me, and when I think him (as distinguished from merely see- ing him), I place him under a class, that is, under an idea wider than himself. And this idea or class I do not construe to my mind as made up of a number of individuals, for these again, however numerous, I should be again compelled by the necessity of thought to place under a class, and so on for ever. When I think a man, I think him as an instance of some-PLATO. 343 thing of which there are or may be other instances to an indefinite extent. This something is innate; it is the principle, the presiding fact or law of the arrangement by which men, and other things, are placed under classes. But it cannot, as I said, be represented or placed before the mind as an object. When viewed as an object, its innate character is destroyed. 30. From what has been said in regard to the Platonic ideas being innate, it might be inferred that they were also subjective, or the proper and peculiar endowments of the human mind. This, however, is not the doctrine which Plato maintains. Ideas are not subjective in the sense of belonging peculiarly to the mind of man; they are rather objective, inas- much as they are the light of all intellect, the prin- ciples of universal reason. No intelligence can ope- rate without ideas, that is, without a capacity of apprehending resemblances and differences, and without obeying those laws of unity and arrange- ment which declare themselves in genera and spe- cies. All intellect must think under the conditions of resemblance and difference, genus and species. These laws, therefore, are objective and not subjec- tive ; they are the laws of things as well as the laws of thought. For the universe and all that it con- tains are constructed in conformity with these ideas, they are constructed under the laws of resemblance and difference, genus and species, and could not344 GKEEK PHILOSOPHY. have been fabricated on any other principles. You must not suppose that when we say that ideas are objective, we mean to assign to them any sort of outward existence. Objective in the sense of out- ward, is certainly not to be applied to them. 31. That these laws and ideas have a reality, a binding and irresistible authority, need scarcely be insisted on as part of the Platonic theory. This follows necessarily from all that has been said in regard to their nature. They are, in fact, the most real existences in the universe, for without them there would either be no universe at all, or that universe would be without form and void, an abso- lute chaos. To repeat, then, in a very few words, the chief characteristics of the Platonic ideas, they are these: first, their necessity; secondly, their uni- versality; thirdly, their power of giving unity to our multifarious cognitions; fourthly, their innate- ness; fifthly, their objectivity; and, sixthly, their reality. 32. It has been a disputed point among philoso- phers, whether, according to Plato, ideas were depen- dent on the will of the Deity, whether they were, in fact, portions of the Divine reason, or whether they were antecedent to and independent of the will and existence of the Deity. Some have held that Plato regarded them as constituents of the Divine reason, others that he viewed them as independentPLATO. 345 entities. The latter seems, on the whole, when rightly explained, to be the truer interpretation, and it may be explained by saying that the ideas are laws to which even the will and reason of the Deity con- forms ; for example, there is a law, i.e., idea, of good and right according to which the will even of the Deity shapes itself, and this doctrine would make the law or idea of right to be in some sense antece- dent to and independent of the Deity. In the dia- logue called Euthyphro, the principal question dis- cussed is this: Is an action good and holy because the gods approve of it, or do the gods approve of it because it is good and holy ? If we say an action is good and holy because the gods approve of it, that would be equivalent to saying that good and evil depend on the arbitrary will of the gods: in this case their will would determine what was right and what was wrong. But if we say that an action is approved of by the gods because it is good and holy, this makes the idea of good and holy to be prior to the will of the gods; to be independent of their arbitra- tion ; to be rather that which determines their will, than that which their will determines. This, rather than the other, is the doctrine to which Plato and Socrates incline. Ideas may, in the Platonic theory, be perhaps coeval with the Divine will and reason; but if there be in either case a priority, the ideas are to be regarded as existing antecedent even to the mind of the Deity. But all that is really meant by this assertion is, that God approves of what is right346 GREEK PHILOSOPHY. because it is right in itself, and not because He by His arbitrary decree has made it right. 33. I shall conclude this sketch of the Platonic dialectic with the remark, that in answer to the question, What is the absolute and universal truth, the truth for all intellect ?—for this, you will remem- ber, is the question which philosophy raises and en- deavours to resolve—in reply to this question, Plato's answer would be: Ideas are the absolute and uni- versal truth, the groundwork of all things; they are apprehended by all intellect, and, therefore, if that which addresses itself to all intellect, if that which all intellect apprehends, be the truest and most real, ideas must be the truest and most real of all things, for no intelligence can be intelligent except by par- ticipating in their light; they are the grounds of all conceivability, and of all intelligible or cognisable existence; the necessary laws or principles on which all Being and all Knowing are dependent. Such is the realism of Plato, a doctrine much truer and more profound than either the nominalism or conceptual- ism by which it has been succeeded. 34. The physics of Plato may be passed over as presenting few points of interest or intelligibility. His ethics have a much stronger claim on our atten- tion. I shall in this paragraph give you a short summary of their scope and purport, and shall thenPLATO. 347 go into their details. Plato's moral philosophy will be best understood by being confronted with that of the Sophists, against which it was specially directed, just as his theory of ideas was designed to refute their theory of knowledge. If man be nothing but an aggregate of sensations, he can have no other end than sensational enjoyment, and no other principle of action than selfishness. Such, accordingly, was the general purport of the Sophistical morality, although some of its expounders recoiled from the extreme conclusions to which their principles led. Others, however, were less scrupulous. They ex- plained the origin of justice in this curious fashion. The best condition, they said, in which a man can be placed is that in which he can injure others with im- punity; the worst is that in which he can be injured without the power of defence or retaliation. But men cannot always assure themselves of the best condi- tion, or guard against falling into the worst. This consideration leads them to a compromise, in which they consent to abandon the former condition in order to escape the latter, the evils of which outweigh the advantages of the other state. This compromise is itself justice, and such are the circumstances in which that virtue originates. From this it follows that the semblance of justice is better than the reality; because the semblance will prevent others from injuring us, while it will yet enable us to injure them to our heart's content.—(Eepublic, ii. pp. 358-9.)348 GREEK PHILOSOPHY. 35. In answer to this Sophistical deduction, Plato argues that justice is not (as this doctrine assumes) an unessential attribute, but is itself the health and organisation of the soul. The semblance of justice, he says, without the reality, is no more a good thing for its possessor than the semblance of order is a good thing in a nation, when all its ranks are in a condition of anarchy and rebellion, or than the ap- pearance of health is a good thing in the human body, when all its organs are really in a state of disease. It is principally for the purpose of showing that virtue must be a reality, and not a sham, that Plato, in his Republic, has drawn a parallel between the soul of man and the political constitution of a state. Just as a state cannot exist unless it is sus- tained by political justice—that is to say, unless the rightful rulers rule, and are aided by the military, and unless the inferior orders obey—so the individual soul does not truly and healthfully exist unless it is the embodiment of private or personal justice, that is to say, unless reason rules the lower appetites, and is aided in its government by the more heroic passions of our nature. In short, just as a state without justice, that is, without the due subjection of the governed to the governing powers, is a state disorgan- ised, so a soul without justice, that is, without the proper subordination of the inferior to the superior principles of our constitution, is a soul undone. A character which wears the mask without having the substance of virtue is no better, indeed is worse, offPLATO. 349 than a sick body which presents the mere appear- ance of health. 36. Such is the scope (in so far as a few sentences can give it) of the moral philosophy of Plato, in its more popular aspect, as presented to us in the Kepub- lic. He treats the subject more metaphysically in the Philebus. But the result reached is in both cases the same. The maintenance of that organisa- tion of the soul in which reason rules and passion obeys, this is the end to be aimed at by man, rather than happiness or pleasure. 37. But more important than any results, either moral or metaphysical, which have been brought to maturity by Plato, are the inexhaustible germs of latent wealth which his writings contain. Every time his pages are turned they throw forth new seeds of wisdom, new scintillations of thought, so teem- ing is the fertility, so irrepressible the fulness of his genius. All philosophy, speculative and practical, has been foreshadowed by his prophetic intelligence; often dimly, but always so attractively as to whet the curiosity and stimulate the ardour of those who have chosen him for their guide. 38. Plato's ethical doctrines are presented in their clearest and most detailed form in his great work, entitled the 4 Kepublic.' * In this treatise his main * The ' Republic' has been translated with remarkable fidelity350 GREEK PHILOSOPHY. object is to show what justice is, and the result of his inquiry is, that justice is in fact the true nature, the true constitution of the soul. It is not something which appertains to the soul as an accidental quality, or as a property which can be assumed or laid aside at pleasure without affecting the innermost life of our intelligent nature. It is, on the contrary, the very essence of the soul. It denotes the equipoise which must be preserved among the different principles of our nature, if that nature is to remain true to itself, and fulfil the functions for which it was designed. And hence, inasmuch as justice is merely another word for the true nature of the soul, and inasmuch as the true nature of a thing is merely another word for the virtue of that thing, justice is to be regarded as emphatically the virtue of the soul. 39. Plato says that this doctrine of justice will be best understood, and that its truth will become more apparent, when we consider it upon a great scale. He says, that by knowing what justice is when we see it as the virtue of a state, we shall more clearly understand what it is when represented as the virtue of an individual. We can readily under- stand how a state or society of men must go to ruin and spirit by Messrs Vaughan and Davies of Cambridge. And Dr Whewell has done good service to the cause of Platonic literature by abridging (with explanations) the more important dialogues, and clothing them in a garb of masculine and idiomatic English, which cannot fail to introduce them to many readers to whom they might otherwise have been uninteresting or inaccessible.PLATO. 351 which is not governed according to the principles of justice ; and we ought just as readily to understand how the soul of an individual man must go equally to ruin when his disposition is not regulated and his conduct guided by the principles of justice. At the outset of the inquiry, Plato had found himself beset with difficulties when he attempted to explain justice as it appears in the individual man; but by looking at it as manifested on a great scale in the organisa- tion of the state, and then by holding that man is but a miniature of society, he is enabled to clear away the obstacles which had obstructed his course, and to carry through his argument in a very masterly and convincing fashion. 40. To explain, then, the nature of individual vir- tue, individual justice, Plato asks what is political virtue, political justice. Find out this, and then you will know what justice is, considered as the virtue of the soul. Understand the virtue of the state as shown in the true constitution of the state, and then you will understand the virtue of the soul as shown in the true constitution of the soul. Now, political justice, the virtue of the state, distributes to every member of the community his proper province of action, and seeks to prevent one citizen from en- croaching upon another. That is the business of the state, and when it is rightly executed a true system or. organisation of society is the result. There are three orders in the state. First, the working order,352 GREEK PHILOSOPHY. the artisans, or, as they are nowadays termed, the operatives; secondly, the military or auxiliary order; and, thirdly, the legislative order. In regard to the first of these classes, their object is gain ; they minis- ter to wants and enjoyments of themselves and the community generally; this, the working order, may also be termed the qucestuary class, from qucestus, the Latin for gain, or the chrematistic class, from xptf/jLara, the Greek for money or wealth, this being the end which they aim at. In regard to the second of these classes, the military order, this is superior to the artisans. It exists for the purpose of preserving internal tranquillity and of repelling foreign agres- sion. It is called the auxiliary class, because its principal function is to aid the legislative order in repressing all such insubordination on the part of the working class as would imperil the existence, or compromise the safety, of the state. Then in regard to the legislative order, its business is to govern the other classes; and it consists of those members of the community who, by their wisdom and probity, are the best qualified to discharge that office. When each of these orders fulfils its proper function, and when none of them attempts to usurp or encroach on the province of the others—when neither the artisans nor the military strive to displace the governing or legislative power, and when the legislative power does not succumb to either of these—the state is duly organised, its true constitution is preserved. It is, in fact, a state; and it possesses and presents thePLATO. 353 virtue of a state. Political justice is embodied and shown forth. 41. Now, answering to these three orders in the state, there are in the soul of man three distinct faculties. 1. Appetite or desire, i.e., the concupis- cible faculty; 2. Spirit or indignation, i.e., the iras- cible faculty; 3. Eeason or the rational faculty. The first of these, the concupiscible faculty, in Greek, imOvfiLa, corresponds to the operative or quaestuary or chrematistic class in the state. Just as this class aims at the attainment of wealth, so does that faculty pursue pleasure as its end. The second of these, the irascible faculty, in Greek, Ovfios, a term which, perhaps, might be tolerably well translated by our common word jpluck—this faculty comprises the more heroic principles and impulses of our nature; and it corresponds to the military or auxiliary order in the state. Just as the military are called in to aid the legislative authority in putting down mob insurrections, so the irascible faculty, that is, the nobler passions, and the reason, unite in resist- ing the solicitations of the lower appetites. The third of these is the rational faculty, in Greek, vovs. This is the governing principle in the mind, to rjye/io- vtfcov, just as the legislative is the governing power in the state. 42. Such is the way in which Plato works out the analogy between the soul of man and the constitution z354 GftEEK PHILOSOPHY. of a civil community. By nature the concupiscible is designed to obey the rational, just as in the state the working classes are designed to obey the legislative power; and the irascible is created to assist the rational, just as the military exist to aid and support the legis- lative. Thus, as there are three orders in the state, so are there three faculties in the soul, each answer- ing to each—the concupiscible to the working order, the irascible to the military, and the rational to the legislative. The virtue of the concupiscible is tem- perance ; in other words, the submission of the con- cupiscible to the rational is the virtue of temperance. The virtue of the irascible is fortitude; the virtue of the rational is wisdom or prudence. When consent and harmony prevail among the three, then that complete virtue which Plato calls justice arises. And this virtue is higher than either temperance taken by itself, or than fortitude taken by itself, or than wisdom taken by itself, for it is the comple- ment of the whole three, and is the result of the harmonious and properly balanced operation of the three faculties of the soul. Just as justice pervades the state, and the wellbeing of the community is the result when each order keeps its own place, and executes its appointed function, so justice pervades the soul, and health and strength of mind are the result when each of the faculties preserves the re- lation towards the other faculties in which nature placed it, and in which nature intended it to stand. When this relation is preserved, the outward life andPLATO. 355 conduct of the individual will not fail to correspond with his internal condition. You thus perceive that Plato makes individual justice, or the highest virtue of the soul, to be itself the very constitution of the soul, just as political justice, or the subordination of the mass to certain governing powers, is itself the very constitution of the state. A remarkable passage from the fourth book of the Republic will show you how it is by close observation to the facts of our nature that Plato discriminates these three powers of the mind, and shows that they are really distinct.—(Rep., iv. p, 439; p. 160 in Yaughan and Davies's translation.) 43. We have now to show against whom was Plato's doctrine of justice, and of the constitution of human nature, intended to be directed. It was directed against the sophists, and he argued thus: if the nature of justice be such that it is necessarily inherent in the constitution of the human soul, is, in fact, itself that constitution, then is the sophistry of the sophists, and of all other cavillers, at once over- thrown. The sophists argued that injustice might in many cases be preferable to justice: they argued that justice was good, and was esteemed, merely because it brought wealth, security, honour, and praise, so that if a man could with consummate art simulate justice, while he was in his soul unjust, he might reap the full reward of justice among men, and be to that extent happy; and, so far as regarded356 GREEK PHILOSOPHY. the gods, he need not, the sophists said, give himself much trouble about them, for they could be pro- pitiated with sacrifices, and kept quiet by means of a few grains of frankincense. In this way the sophists endeavoured to make out that injustice might be a real good to its possessor while justice might prove a real evil. Or, at any rate, they argued that men were just merely because they found it to redound to their advantage, in a worldly point of view, to be so, and that if they could procure the same or greater advantages by being unjust, unjust they would undoubtedly be. They argued very much in the spirit of Hobbes, that men were deterred from committing injustice merely by their dislike of suffering injustice, and knowing that if they per- petrated wrong on others they must be prepared to endure wrong from others in return. 44. In Book i. p. 359, the explanation which the sophists gave of law and justiee (and which you will see resembles very closely the doctrine of Hobbes) is set forth, and the argument illustrated by the story of the ring which the ancestor of Gyges had pos- sessed. Thus the sophists argued that if every man had the ring of Gyges, by which he could make himself invisible at pleasure, then every man would do wrong whenever he felt inclined, and would do right only in so far as it would promote his own happiness. So that the life of an unjust man who can perfectly conceal his motives (as many men canPLATO. 357 and do, even without this magic ring) may be fairly set up as more desirable than that of a just man; and thus injustice may in many cases be preferable to justice, on account of the greater happiness which it brings, and of this every man must judge for him- self. The advantage of probity, therefore, according to the sophists, who sometimes reasoned boldly on these points, although at other times they endeav- oured to hide the extreme to which their principles carried them, did not centre in itself, but in what was exterior to itself, namely, in the honours and rewards which probity procured for the man who practised it. Probity might be said to consist not in being, but in seeming to be honest. The appearance was quite as good as the reality. By all means, said the sophists, be just and virtuous, if justice and virtue make you happy; but if vice and injustice make another man happy, why should not he too follow the bent of his inclinations ? In doing so, he will obey the dictates of his nature, will fulfil the law of his being, just as much as you who pursue a contrary course are obeying the dictates and fulfilling the law of your being. 45. This is precisely the point where Plato enters his dissent, and it was to meet this point that his doctrine of the soul, as made up of three faculties, arranged in the order of superiority and inferiority, and illustrated by the analogous constitution of a social community, was set forth and enforced with all358 GREEK PHILOSOPHY. the power of his genius. Insist on these sophistical opinions as you choose, says Plato, I overthrow them all at one swoop, by asserting and by proving a cer- tain construction or organisation of the soul, to which organisation we must look apart altogether from external considerations of honour or advantage. If justice consists in the due harmony of the three facul- ties of the soul, that is, in the obedience and submis- sion of the inferior to the superior principles, no man can be just by appearing to be so when he is not, any more than a nation or state could delude a neigh- bouring nation or state, if the soldiers, the legislators, and the people, were in a state of anarchy; i.e., if the people were not working, if the military were in revolt, or the legislature overcome by imbecility. A soul in which the inferior principles reigned supreme, or one which presented the mere semblance, but not the reality, of justice, would be a soul disorganised, a soul untrue to its own constitution—a soul, in fact, which was not a soul; just as a state in which the relation of the governed and the governors was re- versed, would be a state which had crumbled into dust. And even suppose the dissimulation to have been carried so far that both the soul and the state appear to be in health and preservation, surely both the man himself and the state itself would know that no balance of power, no true strength, no true life was within them, and that no security was theirs. Injustice, or the want of a proper equipoise among their various elements, would set them at variancePLATO. 359 with themselves, and lay them open to the assaults of all around. Therefore, justice is the strength, the true nature of every soul, just as it is of every politi- cal constitution; and, accordingly, when this simpler and more truthful system of morals was given to the world by Plato, the doctrine of the sophists fell to the ground as an edifice which had no solid foundation. 46. Plato goes on to enforce and illustrate his views by showing that justice is the health, and con- sequently the happiness, of the soul, and that the mere semblance of justice is no more the health and happiness of the soul, than the mere semblance of bodily vigour is the health and happiness of the body. How, asks Plato, is bodily health produced ? It is produced when the ongoings of our physical frame proceed as they have been established by na- ture ; disease inevitably arises when any part of the system is out of joint, or is not governed according to nature. In the same way disease arises in the soul, when any of its parts do not conform to the design of the whole. But justice is itself a confor- mity with this design, is a working in accordance with it, just as injustice is the reverse. Therefore injustice, although its external accompaniments and consequences may be honours and rewards, is the disease, the deformity, the misery, the bad habit of the soul; while justice, even though it should meet with no corresponding external advantages, is the360 GREEK PHILOSOPHY. health, the beauty, the happiness, the good habit of the soul. We speak of a bad habit of body when its parts are in disorder and at variance with each other, and of a good habit of body when its different parts are in harmony. So vice, independently of external considerations, is the disease, the deformity, the cor- ruption, the pollution, the slavery of the soul, inas- much as it indicates that the intellectual system is disordered, and that those principles have usurped the government which were created only to obey: and so virtue, and, in particular, justice, is the health, the perfection, the freedom of the soul, inasmuch as it indicates that the intellectual system is well or- dered, is regulated according to its nature, and that those principles are governing which were intended to govern, while those are obeying which were in- tended to obey. Farther, if the state of the body when diseased be such as to render life a burthen, though it may be surrounded with all the luxuries which wealth can procure, so when the state of the soul is thoroughly corrupted by injustice, it can en- joy no true happiness, no real satisfaction, although crowned with worldly honours and advantages; as Juvenal says:— " Cur tamen hos tu Evassise putes quos diri conscia facti Mens habet attonitos, et surdo verbere caedit, Occultum quatiente ammo tor tore flagellum." —Juvenal, xiii. 192. See especially the passage where Plato speaks of the rightly balanced condition of the soul, which con-PLATO. 361 stitutes justice.—(Plato, Eep., B. iv. pp. 443, 444; pp. 167, 168, 169 in English translation.) 47. You will thus perceive that Plato argues in favour of justice as the true condition of humanity, by looking, not to any external advantages or disad- vantages which justice may confer, but by looking to the internal economy of human nature itself, and by showing that justice is nothing more or less than the maintenance of that economy in the order which nature has established, just as bodily health is noth- ing more or less than the maintenance of the order and arrangement which nature has established among the various organs of our physical framework. 48. The object with which Plato instituted the analogy or comparison between the soul of man and the constitution of a political state was this: it was to show that just as there can be no political state without justice, that is, without a proper balance and subordination being preserved among the differ- ent orders of society; so there can be no soul, or true rational life, in man, without justice, i.e., with- out a proper balance and subordination being pre- served among the different parts and principles of the soul. Justice in a man has its analogies on a large scale in justice in a state; and just as the state ceases to be a state and goes to ruin so soon as jus- tice deserts it, i.e., so soon as confusion and insub- ordination prevail among its ranks ; so the soul goes362 GREEK PHILOSOPHY. to ruin so soon as justice departs from it, i.e., so soon as its inferior principles prevail over its superior ones, so soon as what was meant to obey presumes to take the office of governor. 49. The philosophical school founded by Plato is known in the history of philosophy as the Academy, so called from the groves of Academus where Plato was in the habit of addressing his disciples. The Academy is usually divided into three, the old, the middle, and new. The latter two may occupy our attention for a brief period hereafter: meanwhile I speak merely of the old Academy, which embraced and was presided over by the immediate followers of Plato. None of the writings of these older Platonists have come down to us. All that is known of their opinions is gathered from a few brief and incidental notices which occur in certain ancient authors. We are not, therefore, in a position to speak with any certainty of the manner in which they may have modified or carried forward the philosophy of their master. I shall merely make mention of Plato's three more immediate followers, Speusippus, Xeno- crates, and Polemon, who succeeded him as the heads of the Academy. 50. Speusippus was the nephew of Plato. He was born probably about 400 B.C.—a calculation which makes him about thirty years younger than hisPLATO. 363 uncle. He was a native of Athens. He accom- panied Plato on his third journey to Syracuse, and is said to have shown much prudence and address amid the troubled atmosphere of the court of Dionysius. His active and moral powers were by all accounts greater than his intellectual acuteness. On the death of Plato in 347, he became his successor in the Aca- demy, having been so nominated by Plato himself. Aristotle may have looked forward to that elevation as a position to which he was well entitled to aspire. But Aristotle was destined for higher things than to be the follower even of so great a philosopher as Plato. Although he has much in common with his master, he was rather fitted to found a new dynasty in philosophy than to be the continuator of an old one. Aristotle, not long afterwards, became the founder of the peripatetic school of philosophy, which held its meetings in the Lyceum. Speusippus continued president of the Academy for about eight years. He was compelled by a lingering illness to relinquish the office some time before his death, which probably took place about 330 B.C., or it may be somewhat earlier. He is said, in particular, to have lectured against the hedonism of Aristippus. 51. Xenocrates, who succeeded Speusippus as pre- sident of the Academy about 340 B.C., was a native of Chalcedon, a city on the shores of the Bosporus. He was born in 396. In early life he came to Athens, and attached himself to Plato. Like Speu-364 GKEEK PHILOSOPHY. sippus, he accompanied the philosopher on one of his visits to Syracuse. After Plato's death, Xenocrates went, in company with Aristotle, to the court of Hermias, the ruler of Atarneus, in Mysia, a province of Asia Minor. He cannot have remained very long in this retreat; for we are told that he was frequently sent by the Athenians on embassies to Philip of Macedon, with whom they were at this time em- broiled, and by whom, in the year 338, they were ultimately subjugated. When the failing health of Speusippus compelled him to resign the presidency of the Academy, Xenocrates was summoned to the vacant post, and this office he occupied from about 340 B.C. until his death in 314, when he was in the eighty - third year of his age. The temperament and the morals of Xenocrates were grave, not to say austere, in the extreme. His name was quoted in antiquity as almost a synonym for unselfishness, modesty, tem- perance, and continence. None of his works have come down to us, so that we cannot speak very particularly in regard to his opinions. Only their titles are extant, and these are sufficiently tantalis- ing. From them we learn that he prosecuted dili- gently the researches in which his great master had led the way. He wrote on dialectic, on knowledge, on ideas, on the existent and the one, on the oppo- site, on the indefinite, on the soul, on the pas- sions, on happiness and virtue, on the state, and several other topics. These writings are extremely multifarious in their subject; and that the sub-PLATO. 365 jects were treated of by Xenocrates in an able and interesting manner, we may infer from the fact that Aristotle thought it worth his while to write commentaries on some of these treatises. Xeno- crates is said to have insisted particularly on the distinction laid down by Plato between ato-Orjo-Ls, So£a, and iirurrriijuq. By he probably under- stood the relative and contingent truths of the senses; by So£a the relative and contingent truths of the understanding; and by i7riar7]fi7] the absolute and necessary truths of the reason—the truths, i.e., for all, and not merely for some, intelligence. 52. The name of Polemon must be ever associated with that of Xenocrates in the history of philosophy. Polemon was notorious for his profligacy and dissipa- tion ; but happening one day to enter the Academy with a crowd of gay companions with whom he had been revelling, he was so much struck by the dis- course of Xenocrates, who was lecturing on the ad- vantages of temperance, that he tore from his head the chaplet of flowers with which he was crowned, and determined then and for ever to renounce his former way of life. He continued true to his resolu- tion: he became the most temperate of the tem- perate, and studied philosophy so assiduously that he became the successor of Xenocrates in the presi- dency of the Academy in the year 314 B.C. He died in 273, having been born about 345.AEISTOTLE. 1. The writings of Aristotle, even in the imperfect state in which they have come down to us, are exceed- ingly multifarious. They are usually divided by his commentators into three departments: 1st, Logical; 2d, Theoretical; and, 3d, Practical. Under the logical division are comprised the treatises called the Or- ganon. Under the theoretical division are placed the physics, mathematics, metaphysics, and the treatise on the soul. Under the practical division are com- prehended ethics and politics. There also extant a work by Aristotle on rhetoric, another on poetics, and several minor treatises. The only works of Aris- totle on which I propose to touch in these lectures are the logic, the metaphysics, the treatise on the soul, and the ethics, and of these the ethics alone shall engage a considerable share of our attention. 2. The logic which you have already studied else- where is derived entirely from Aristotelian sources: and therefore, as I may presume that you are already familiar with its details, I shall touch very cursorily on this part of Aristotle's philosophy. The logic ofARISTOTLE. 367 Aristotle is usually termed formal or deductive, to distinguish it from the inductive logic, for which Bacon usually gets the credit. It was at one time, and not very long ago, supposed that the inductive logic, which studied real nature, was much more valu- able than the deductive logic, which merely scrutin- ised mental processes; but it is now generally acknow- ledged that both sciences are equally worthy of our attention. In point of technical precision, the logic of Aristotle, and in particular his doctrine of the syllogism, is unrivalled; and it is not a little remark- able that it should have sprung at once into perfec- tion. The industry and ingenuity of more than two thousand years have added little or nothing to the symmetrical beauty, the finished excellence, of the logical system of the mighty Stagirite. Aristotle's logical treatises have been collected together under the general title of the Organon. The Organon com- prises treatises on the Categories (/ca^rfjopLai), and on the interpretation or expression of thought, 7repl epfirjveia,? (the genuineness of these writings, however, has been doubted). It contains a treatise called the Prior Analytics (dvaXvriKa 1rpore pa), which deals with propositions, and another entitled avaXvTL/ca varepa, which deals with proof, definition, and divi- sion. It also contains tottikcl, or topics, a treatise on probable reasoning, and a treatise on sophistical fal- lacies and their solution (irepX croi<7Ti/ca)v e\eY%c*>z>). These are the logical writings of Aristotle. They deal with the method of science, and are therefore368 GREEK PHILOSOPHY. classed together as the Organon or instrument of in- quiry. The Categories, or general heads under which all things may be classed, are the following ten: ovata, or substance: iroaov, quantity; ttolov, quality; 7rpo9 Ti/f relation; nrov, where; 7roTe, when; KelaOai, position; having ; 7roieZv, doing; iraa^tv, suf- fering. These might be reduced to two, substance and accident; or, viewed logically, subject and predi- cate: thus overia is the subject, for example "man," and all the other categories denote what may be predi- cated of man. Thus, whatever we say of man must be either something about his size, or his qualities, or his relation to other things, or the place where he is or was, or the time when he is or was, or his atti- tude, or his possessions, or his actings or sufferings. Aristotle's scheme of the Categories must be pro- nounced crude and imperfect, whether we regard it as a table of things or as a classification of the forms of predication. 3. In his work, entitled the 4 Metaphysics/ or first philosophy, as he himself calls it, Aristotle treats of the principles common to all things, the universal constituents of Being. The term metaphysics is not employed by Aristotle. The explanation usually given of the origin of this word is, that some early commentator on Aristotle, finding certain treatises placed after the physics in the arrangement of his master's works, gave to these treatises the superscription ra fjuera ra (j>v?7 is vocabulary not by any means limited to intelligence. It signifies, in its widest sense, the power or principle of life; and in this sense it is376 GREEK PHILOSOPHY. what he calls the eVre\e%eia, or perfected organisa- tion of the body. There is a scale or series of these organisations in nature, rising one above another ; and of these the higher forms always contain the lower. Thus, there is, first and lowest, a plant soul, or life in vegetables. This is a mere principle of nu- trition and reproduction, to Opeim/cov. Plants are able to assimilate what is necessary to support them, and to continue their like. Then, secondly, there is an animal soul, a principle of animal life, which consists in sensation, desire, and locomotion, to alaOrjTLKov, to ope/cri/cov, to KivrjTifcov (Kara tottov). The functions of this principle are directed and checked by a mod- erating power (dpxv)> which is altogether wanting in plants. The higher animals have some degree of fanc^ (
