JENKINS, SUFFOLK CO., N. Y. 20 NORTH WILLIAM ST., N. Y. PREFACE The lectures constituting the present volume were delivered in April, 1883, before the students of the Theological Seminary and Rutgers Col- lege, at New Brunswick. When chosen to lecture on the Vedder Foundation I thought I could not better accomplish the object designed, than to present so far as could be done in the course of five lectures, the line of argument which had brought satisfaction to my own mind when con- fronted with the chief of the problems presented by modern science. In the discussion I have sought to be just and fair to science as well as to religion. As the reader will see, instead of com- bating Evolution as altogether inadmissible, I concede a possibility of its truthfulness, and aim to show that the believer in God and a Rev- elation, has nothing to fear from it as a foe to religion, when its postulates are freed from as- sumptions, and its truths are separated from its untruths. It was the expressed wish of the founder of the lectureship that the courses de- iv PREFACE. livered should be published and thus reach a wider audience than that immediately addressed. The present volume is sent forth in compliance with that wish, seconded by the oinnion of those who heard the lectures, that they would prove useful in clearing up some of the difficulties with which many honest and thoughtful minds are troubled in view of claims that are made in the name of science. The lectures are printed as delivered, except that an occasional note has been appended. They are sent forth with the earnest prayer that they may be helpful in a period so full of questionings and doubtings as the present. J. B. D. Ghent, N. Y. November, 1883. CONTENTS. LECTURE I.

The scope of the lectureship, in accordance with whose terms I appear before you, is de- fined, by the instrument establishing it, as " a course of lectures on the present aspects of modern infidelity, including its cause and cure." In coming to the consideration of this gen- eral theme, I am profoundly impressed by the fact that in our day the chief and most formi- dable assault on our Christian faith comes from the side of the natural sciences. Speaking in the name of these sciences, which seek to usurp to themselves the very name of science, unbelief challenges the very fundamentals of religion, and is insidiously giving an infidel tone to modern thought and literature. A chief danger to religion lies in this direction. Do not understand me by this 2 TRUTHS AND UNTRUTHS to affirm that the students of nature are pre- dominantly unbelievers, and that natural sci- ence itself is necessarily materialistic, atheistic or infidel. On the contrary, it can be estab- lished that the chief contributors to a true science of nature have ever been devout Chris- tians, and a legitimate science is to-day, as always, the friend rather than the foe of true religion. What I would emphasize is the fact that, to-day, natural science is relied upon to furnish to every school of antagonists to religion, such weapons as they have, — is, in other words, both the arsenal and citadel of modern infidelity. It has become such through the growing influence of the scientific hy- pothesis known as evolution, and the fre- quent assumption, that it has made untenable faith in God and the Bible. Always and everywhere the root of unbe- lief is the natural opposition of the heart to God and His law. The vast majority of unbe- lievers are merely inattentive or indifferent to the claims of religion, — they neither seek for nor give, a reason for their unbelief. But this course does not suffice for all, nor perma- nently for any. Men cannot escape thought, and if questioned by none else, the soul must give a reason to itself for its doubts and un- belief. A thoughtful man cannot be content OF EVOLUTION. 3 without some plausible reason for not accept- ing the strong and seemingly invincible claims of Christianity. The situation, to-day, is sub- stantially this, — that nearly all who reject our revealed faith and the religion of Christ are depending for a logical defence in so doing on the scientific theory of evolution. The real battle, therefore, in our day between the Christian faith and infidelity is waged in this field of thought, and the issue is over the ex- istence of a personal Deity. Unbelief, speak- ing in the name of evolution, boldly asks: — Is God any longer to be considered as a ne- cessary factor in the history of the universe ? The questions contended over within the pale of Theism, — such as prophecy and mir- acles, the credibility and authority of the Bible, the person and work of Christ, — are, in this new phase of the struggle, relegated to a subordinate position. The assailants tacitly, if not avowedly, concede that on these issues, granting the postulate of an intelligent per- sonal creator and governor of the world, the battle has gone against them. If there has been a creator and ruler, such in His being and works as we have been ac- customed to infer from the evidences of wis- dom and beneficence so conspicuous in nature, everything essential to the Christian system 4 TRUTHS AND UNTRUTHS is made both possible and probable. Kevela- tion and redemption, providence and miracles and prayer, fit so readily and perfectly into the system that they altogether cease to be anomalous or incredible. It is coming to be discerned that to concede the possibility of a revelation removes the chief ground 'for re- jecting its contents, that if there be such a thing as the supernatural, the position of Christianity after centuries of futile assault is left well-nigh impregnable. Hence the cause of infidelity practically depends on its success in denying God and the supernatural. Until recently this seemed so impracticable that few skeptics were willing to join issue at this point. Now, as has been said, it is the chosen ground of battle, and it is boldly claimed that the world and its inhabitants have come into being, and are what they are, through a process of unintelligent mechanical evolution, which not only makes unnecessary, but actually excludes, the intervention of any supra-mundane power, and does away with creation and a creator, save it be as an im- personal, initial force. The issue thus presented by the infidel cannot be evaded, and the believer of all others need have no wish to evade it. It necessitates a careful examination of the position behind OF EVOLUTION. 5 which, the enemy has entrenched himself, and presents to ns the question whether the use which is sought to be made of this latest gen- eralization of science be legitimate. Perchance there may be a wide difference between evo lution, and evolution as the excuse for unbelief. At all events it will be timely to inquire into the state of the question, and seek to learn how much of truth and how much of error there may be in this hypothesis of science, which bears so directly upon our most fundamental religious beliefs. Called therefore as I am to discuss "one of the present aspects of modern infidelity," and viewing the situation to be such as I have sketched, it has seemed to me I could not do better than examine with carefulness and candor the present state of the case. If I shall do nothing more than map out the issues, and exhibit what is fact, and what theory and assumption, in the postulate so boldly appropriated by the unbeliever, I shall feel my labor has not been lost. For many a problem, when its terms are freed from ambi- guity and confusion — when it is once simply and correctly stated — is near to a solution. I propose to examine, therefore, as honestly, dispassionately, and carefully, as is possible, the evolutionist's hypotheses, and their appli- 6 TRUTHS AND UNTRUTHS cations, accept truth wherever it is found, and eliminate, as far as it is discoverable, that which is false. My general topic can properly be formulated as, "The Truths and Untruths of Evolution." I am addressing, I assume, those who are with me believers in God and the religion of the Bible. My aim will be not so much to convince the unbeliever, to confound or convert the infidel, as to confirm faith and dispel doubt. If I may suggest anything to help the hon- est doubter, or relieve the fears of those to whom it seems that the very citadel of our faith is in danger, I shall be content. As for the confirmed skeptic, if the intuitions of the soul, and the witness of the conscience to God, do not convince, I am persuaded no amount of reasoning will avail to do it. What I submit for your consideration is the fruit of much careful investigation and thought, and though laying no claim to originality or novelty, beyond what always appertains to independent thinking, it will I trust prove suggestive and useful as an aid in studying the present position and probable future of the evolution hypothesis. It is sometimes charged that faith in God and Christianity must necessarily incapacitate OF EVOLUTION. 7 and unfit one for the fair and unbiased treat- ment of such a subject. Perhaps it does for an unbiased study of a postulate that excludes God and the supernatural, but not of any ques- tion that is essentially one of science, as evo- lution properly and legitimately is. But aside from this it may well be doubted if it is pos- sible, or desirable, for an earnest and thoughtful man to come to the examination of any ques- tion entirely unbiased. However, in the case before us it will be conceded, I doubt not, that the believer is no more unfitted by his faith, than the skeptic by his want of faith, to deal fairly in the matter. The scientific spirit ought to be especially truth-loving, and dispassionate, yet one can read but a little way in the so-called science of the day, without discerning not merely an indifference to the bearings of its conclusions on the conception of God, and the postulates of religion, but an absolute anxiety to escape even the supposition of God, and a persistent effort to magnify the so-called antagonisms of science aud religion. This manifests, we submit, a bias against, much less favorable be- cause harder to overcome, to the dispassionate investigation of truth, than a bias/or, God and religion: since the latter rests on kinds of evidence as substantial and satisfying as the 8 TRUTHS AND UNTRUTHS evidence for scientific truth. In other words, I believe one is better equipped for finding the truth, who believes, on the testimony of his own soul and consciousness, and the phenomena of mind and spirit, that there is a God, than one who ignores every kind of truth, save that discoverable by scientific induction. At all events, it shall be my endeavor to preserve throughout the discussion, at least as fair and honest a spirit, as those who appeal to science to excuse their infidelity. Necessarily, in so brief a course as this, there is time only for hints and suggestions. I shall need confine myself to the barest outlines of thoughts and arguments, hence I shall in many cases, be able to no more than indicate the course of treatment fullest of promise in the interest of truth, and leave it for each to fol- low it out for himself. EVOLUTION THE HYPOTHESIS. Evolution is the general name for that meth- od of accounting for existing diversity, which supposes present complexity to be the result of successive and gradual modifications of simpler forms. It makes the development of the individual from the germ, by successive but closely connected differentiations, to be OF EVOLUTION. 9 the image and type of the genesis of all ex- isting beings. One of its clearest and ablest expounders, Huxley, defines the term, when employed in biology, "Asa general name for the history of the steps by which any living being has acquired the morphological and the physio- logical characters which distinguish it." 1 He has applied this definition both to the genesis of the individual, and to the sum of living beings, but when given in connection with the latter the definition receives an ad- dition, from which, I believe, proceed most of the untruths discernible in its applications. Evolution in this definition becomes much more than the Idstory of nature's transforma- tions. He says, " Evolution is the process by which the physical world and all things in it, whether living or not living, have originated through the continuous operation of purely physical causes out of a primitive relatively formless matter." •Article "Evolution," Encyclopaedia Britannica. Our quotations of the views of leading evolutionists are taken as far as possible from the ninth edition of the Ency- clopaedia Britannica, rather than from their published works, both as more convenient and as embodying the later and more matured opinions of the advocates of evolution. 10 TRUTHS AND UNTRUTHS To the same purport is the definition of other evolutionists. Herbert Spencer's is substantially this: — " Evolution is a change from the homoge- neous to the heterogeneous, from the indefi- nite or undetermined, to the defined or deter- mined, from the incoherent to the coherent; and the causes of these changes are involved in the ultimate laws of matter, force or motion. The rationale of which is a distinctly mechan- ical process." James Sully, author of the article on "Evo- lution in Philosophy" in the last edition of the Encyclopcedia Britannica, thus defines it: — "Evolution includes all theories respecting the origin and order of the world which re- gard the higher and more complex forms of existence as following and depending on the lower and simple forms, which represent the course of the world as a gradual transition from the indeterminate to the determinate, from the uniform to the varied, and which assume the cause of this process to be imma- nent in the world itself that is thus trans- formed." In all these definitions we note that they make evolution not merely the history of a process, but equally the complete account of its causality. OF EVOLUTION. 11 By the legerdemain of a definition, other than second causes are barred out. As Hux- ley expressly says when speaking of man's place in nature, " He is now known to be the last term in a long but uninterrupted series of developments effected without intervention of any but what are termed secondary causes." It is this limiting of causality to purely me- chanical forces, this exclusion of other causes than those immanent in things themselves, that has served so generally to identify evolution with materialism. It is emphasizing this feat- ure that enables the infidel to claim that the hypothesis of a personal creator is no longer necessary. The universe, under this concep- tion, becomes not merely a mechanism but a self-evolved and self-evolving one, possess- ing within itself the causes of all its trans- formations. It is true that Huxley and Spencer and Sully, would probably disclaim the intention to absolutely exclude any other than mechan- ical causality, and would possibly append to their expressions, if pressed, the saving clause, "/. c, any other cause that science knows about." Indeed Spencer expressly says that " while all phenomena can be formulated in terms of mat- ter, motion and force," these are, in the last analysis, "but symbols of the unknown real- 12 TRUTHS AND UNTRUTHS ity;" and escapes with many others the logi- cal sequence of bald materialism, by admit- ting, back of and beyond second causes, an unknown and unknowable potentiality. So long however as the causality is made an in- tegral part of evolution, and that a causality inherent in things themselves, the definition of Hseckel is to be preferred, both for its frankness and its clearness, when he says: — "The general theory of evolution assumes that in nature there is a great, unital, con- tinuous, and everlasting process of develop- ment; and that all natural phenomena with- out exception, from the motion of the celestial bodies and the fall of the rolling stone, up to the growth of the plant and the consciousness of man, are subject to the same great law of causation; that they are ultimately to be re- duced to atomic mechanics." Now, just so far as exponents of evolution assume to exclude the operation of causes other than those inherent in matter, they transcend the limits of a true science. It has to do merely with the how, and not the whence, of things. Dr. Carpenter, in his address before the British Association in 1872, justly says: — " When science sets up its own concep- tion of the order of nature as a sufficient OF EVOLUTION. 13 account of its cause, it is invading a province of thought to which it has no claim." "To set up the laws of nature as self-acting, and as excluding or rendering unnecessary the power which alone can give them effect, appears to me as arrogant as it is unphilosophical." So also W. Stanley Jevons, in his full and ex- haustive treatise on " The Principles of Science," in controverting the idea that "the course of nature is being determined by invariable prin- ciples of mechanics, which have acted since the world began and will act for infinite ages to come," says, "Such notions I would de- scribe as superficial and erroneous, being de- rived, as J. think, from false views of the nature of scientific inference, and the degree of cer- tainty of the knowledge which we acquire by inductive investigation" (p. 430). Further on, in another connection, but speaking of the same class of scientists, he says, "there is an erroneous and hurtful tendency to rep- resent our knowledge as assuming an approxi- mately complete character" (p. 449). These authorities will suffice, I take it, to bear me out in the declaration, that it is unscientific and pure assumption, to assert that there have been no causes at work in producing present diversity except those cap- able of scientific analysis. 14 TRUTHS AND UNTRUTHS There is no ground, except as it is hidden away in the terms of a faulty definition, for the postulate that the process of evolution has known no other causality than that in- herent in nature itself and discoverable by science. We are willing to accept what science can demonstrate, and feel ourselves the richer for its many contributions to our stores of knowl- edge, but we cannot accede to the claim that there is nothing real or credible beyond the narrow limits in which its observations are made. There is much truth outside of what can be measured and weighed by the appli- ances of a purely natural science, and it is not by any means axiomatic, as some scientists seem to imply, that what science cannot formulate is either non-existent or unknow- able. The fact is that science itself is ever, and on all sides, meeting with phenomena inexplicable by its formulated or discovera- ble causes. As Jevons well puts it, "The more we have explained the more there is to explain." Sir W. R Grove, whose name is inseparably associated with "the correlation of forces," con- cedes his inability to pass beyond the phenom- ena of light, heat, electricity, magnetism, mo- tion and chemical aifinity. He says, " We OF EVOLUTION. 15 are totally unacquainted with the ultimate generating power of each and all of them, and probably shall ever remain so; we can only ascertain the normse (the rules) of their action :" from all which it is clear that, from the standpoint of a true science, anything in the definition of evolution that limits its causes, and excludes all others than those immanent in the world itself, is unscientific, and nothing but an arrogant assumption. This may be accounted one of the untruths of evolution, as it is the parent of many others. Excluding this gratuitous limiting of its cau- sation, it seems most probable that evolution, considered as descriptive oithe process by which the world has come to its present condition, is likely to become established. Already with the majority of scientists is it accepted as a working hypothesis, and each year is adding to the number of those who in this sense are evolutionists. In other words, that the universe and living beings have come to their present condition through a process of gradual modification of previous conditions, — i. e., through a develop- ment, an evolution, — is coming to be regarded as harmonizing more facts and offering fewer difficulties than the un til-recently-accepted hy- pothesis of special creations. It is in this as- 16 TRUTHS AND UNTRUTHS pect, in presenting the present as born of the past, that evolution has in it an important and valuable truth. A half-century ago men were beginning, through the progress of geological investi- gations, to gather the idea that the earth had not come into being as it is now, but that it had been progressively fitted to be the support of life and the home of man. But while thus abandoning the idea that God by a single fiat had fashioned the dwelling- place, nine-tenths and more of all the stu- dents of its living inhabitants were studying them in the light of the accepted hypothesis, that every true species of the vegetable and animal kingdoms, now existing, had origi- nated in the simultaneous creation of a first pair. This was so generally held, not, as the skeptical scientist is fond of asserting, be- cause of the accepted theological or biblical theory of the origin of things, but because the idea of permanence was embodied in every accepted definition of what constitutes a species. De Candolle, the botanist, defined a species of plants by saying, "We unite under the des- ignation of a species all those individuals that mutually bear to each other so close a resera- OF EVOLUTION. 17 blance as to allow of our supposing that they may have proceeded originally from a single being or a single pair;" and Cuvier, an equal authority as a zoologist, defined a species as "a succession of individuals which reproduces and perpetuates itself." So long as these de- finitions were accepted as correct, there was no escape from the inference that each species must reach back to an original pair, and that they had proceeded directly from the hand of the Creator. The immutability of species was then an in- superable, as it is even now a serious, difficulty, in the way of the acceptance of any hypothesis of evolution. The strength of this objection has been weakened, but not altogether destroyed, by the Darwinian theory of natural selection, to the promulgation of which, and to the inves- tigations which it has stimulated, are princi- pally due the influence and wide acceptance of evolution. Whatever may be the ultimate fate of Darwin's particular theories, it is beyond question that he inaugurated a revolution in scientific methods, and lived to see evolution become the prevalent working hypothesis of science. And yet the acceptance of the later theory, so far as it has been accepted, is due much 18 TRUTHS AND UNTRUTHS less to the positive arguments in its favor, than to those negative ones which have tended to its advantage through casting a doubt on, or positively disproving, the earlier hypothesis. It has not yet been satisfactorily shown how species have originated, nor that a true species is other than immutable, and yet it has been made certain that if species were created it was not in the way and manner formerly supposed. And this has been so generally accepted that evolution is regarded as a ten- tative and probable hypothesis — at least as a method of creation — by many who fully dis- cern the weakness of its positive arguments. The original hypothesis of special creations covered not only the fact of a creation, but a particular mode of creation. It supposed a special fiat for each species, that each primi- tive pair came into being in maturity and all simultaneously. The advance of geological science demon- strated long since that the old conception of a simultaneous creation of all types was erro- neous ; new species have been appearing upon the scene all along the course of earth's geo- logical history. The present geographical dis- tribution of living forms shows that many species of plants and animals are limited in their geographical range, and that continents OF EVOLUTION. 19 and seas and islands, as well as the different zones, each have their flora and fauna, so that different centres as well as different epochs of creation must be supposed. Beyond this, the vast and rapid growth in the number of species — each, under the old definition of species, a special creation, — has served to raise the question, whether it be not more rational to attribute at least some of these variations to modifications by de- scent. For example, the total number of animal species described up to 1831 was 70,000, in the fifty years since the number has grown to 320,000, while it is estimated that not a day passes without adding to the list. Not less than 12,000 species of insects alone it is stated are awaiting description in the museums of natural history. In the vege- table kingdom the number of species is even more numerous. And when we add to the recent forms those of the geological series, the estimate of fully 2,000,000 different spe- cies as the total does not seem excessive. 2 When we remember that among these mul- titudinous species many are separated by mi- nute characteristics, and all from the highest to the lowest so gradually shade off one into another that it is difficult to draw dividing 2 See Lubbock's "Fifty Years of Science," p. 15. 20 TRUTHS AND UNTRUTHS lines, we can readily understand how many scientists came to question whether independ- ence of origin was necessary to the idea of a species, and whether the old conception of the mode of creation did not need modification. It was such facts and considerations as these that led Darwin and Wallace independ- ently to formulate the theory of " survival of the fittest," and convinced many that it is necessary to modify the creation hypothesis, so as to reduce the number of special creations, and give greater potency to secondary causes in producing existing diversity. The modern progress of biology, in calling attention to the community of embryological substance and form, the identity in plan of structure which brings into relationship most diverse individuals, and the presence in many species, of rudimentary organs of which there can be given no satisfactory explanation on the theory of independent creation, has con- tributed still further to give probability to the theory of modification by descent. The same science, by demonstrating that dif- ferentiation begins way back in the nucleus of protoplasm, beyond the detection of the microscope or chemical analysis, gives the highest probability to the theory that God when He creates does so by touching the OF EVOLUTION. 21 hidden sources of being, and leaves the vis- ible form to shape itself by the interaction of inherent properties and general laws. All this renders it probable that things and beings are what they are by some process of gradual modification. To it properly attaches the name of evolution, provided it be supposed to begin subsequent to the creative act. Evolution, regarded as descriptive of a pro- cess in nature, has much, we thus see, to commend it, but' it ought to be distinctly re- membered and emphasized that it is as yet a mere theory, and must not be regarded as having more than a hypothetical value. In whatever form it be held, — whether that be- hind which infidels and agnostics hide and defend their unwillingness to believe, or that which many Christians hold in conjunction with their faith in God and the Bible, — it must not be lost sight of, that it is yet un- proven, and may not properly be used for any other purpose, or in any other way, than is legitimate for an hypothesis. Because a theory harmonizes with very many facts, with more than a previous or rival theory, does not make it any less a theory, or convert it into an established principle. The key that fits all the wards of the lock is the only true key, and only the theory that fits all the 22 TRUTHS AND UNTRUTHS facts may be accounted the absolutely true one. Few scientific theories to-day can en- dure this test, and least of all this of evolu- tion. However, for purposes of investiga- tion and as a help to scientific progress, a theory — an hypothesis — may be most use- ful, even if unestablished, and possibly or even probably erroneous. Science has made and is making her progress with just such hypotheses, scarcely any but what are contra- dicted at certain points and so strongly as to awaken the suspicion that a new and broader generalization will some day succeed them. The nebular hypothesis has yet to fit into itself the anomalous movements of the moons of Uranus. The atomic theory so useful in developing our knowledge of chemistry has had to be modified again and again, and in the opinion of many chemists is almost certain at no distant day to give way to a theory more consonant with all the facts. The mo- dulatory theory of light seems almost mathe- matically demonstrable, yet the difficulties presented in the supposition of a transmit- ting ether are such as to strongly suggest that the ultimate explanation of the old time "imponderables" and the present "correlated forces" has not yet been reached. We cannot dispense with either of these by- OF EVOLUTION. 23 potheses, they fit into more of the facts than an}' other, and yet each is, after years of in- vestigation, nnestablished, and will possibly some day be superseded by some more com- prehensive and truer generalization. If it be so with these older and better tested theories, how much more need of a cautious and ten- tative use of that which has only yesterday become probable. No one who is at all imbued with a proper reverence for true science can do other than protest against that advocacy of evolution which claims for it triumphant establishment, and reasons from it as from a very axiom of science. It has indeed a possible truthfulness, but its difficulties are yet many and great. If I were to formulate a definition of evo- lution, such as the present condition of our knowledge warrants, it would be this: — Evolution is that hypothesis which sup- poses the process by which present diversity in nature has been reached to have been one of progression ; the more complex and better endowed, proceeding in accordance with laws imperfectly known, out of simpler and lower forms. It seems probable there has been some such evolution as this, and this is as far as a scientific definition is able to go. 24 TRUTHS AND UNTRUTHS The philosophical forms of the evolution theory, i. e., the forms it assumes when co-or- dinated Avith other knowledge, and applied to the world-old problems of the "whence" and the "whither" of the universe, are principally three: — Materialistic, Agnostic, and Theistic The first is characterized by the recognition of nothing but efficient or mechanical causes, rejecting all forces other than those inherent in nature itself. Hence is eliminated from the universe the First Cause — a personal, intelli- gent, self-existent Creator, and equally final cause, the supposed evidence of design. Such evolution is simply blind, unintelligent pro- gression, controlled by merely natural forces, from fire-mist to man. It seeks vainly to give any plausible account of origins, and makes man — doomed to die, and a mere automaton — the highest product and the only goal, of this mechanical process. It abounds in startling assumptions, and, its advocates themselves being witnesses, it is wanting in essential evidence at well-nigh every vital point. This perceived weakness of the argument for a purely materialistic ev- olution would seem the real occasion for the formulation of the second form of the hy- pothesis, the agnostic, which diifers from the materialistic only in granting the possibility OF EVOLUTION. 25 of a cause, back of and higher than mechan- ical force, but claiming* that its existence and its nature are alike unknowable. This " un- knowable" is so plainly nothing but a cleus ex mackina, a mere device to escape a formal denial of a first cause, that it is of little weight. As in all else, agnostic evolution agrees with materialistic, we shall in our further discus- sions treat them as one. The difficulties of materialistic and agnostic evolution, and the failure of their advocates to meet them, will be considered in our succeeding lectures, treat- ing of the applications of the hypothesis; for which reason we shall not now pause to con- sider them further than to make a remark or two on a fundamental characteristic, — their denial of what are known as final causes. These must be eliminated from nature or else they abide, as they have ever been re- garded, the conclusive proofs of the existence of a God — the Cause of causes, and the solid basis of a knowledge of His attributes. Hence, many and beautiful and complicated as are the contrivances and adaptations to be noted everywhere in nature, admirable as are the adjustments by which beneficent ends are secured, Ave are bidden to see in them all, noth- ing foreseen or intended by a superior power, but only the necessary outcome of the fortui- 26 TRUTHS AND UNTRUTHS tous interaction of unintelligent and unchange- able forces, called laws. "It is plain," as says Janet in his unanswered and I believe unan- swerable argument in defence of final causes and the old teleological method, " that this is nothing but the theory of chance under a learned disguise." He says substantially: "If by evolution anything more is intended to be expressed than the gradation of organic beings, rising step by step, or at intervals, from the less perfect to the more perfect forms, — a pro- cess that necessitates the idea of intelligent control, it is only another name for the Epi- curean's fortuitous concourse of atoms, and expresses the successive gropings of nature, until favoring circumstances bring such a cast of the dice as evokes an organization that can survive. And when evolution, in admitting nothing but efficient causes, brings itself to this position, it is exposed to the objections that in all past time have been urged against the idea that the world can be the product of chance." 3 There is in phenomena, a manifest working unto an end, and no system that denies this 3 See Janet's "Les Causes Finales," original edition, p. 416. And "Final Causes," the translation of the sec- ond edition, p. 282. OF EVOLUTION. 27 will ever commend itself as true to nature. This has been well elaborated by the Duke of Argyle, as well as the French savant, neither of whose arguments have been successfully met. The fact that the difficulties in the way of materialistic or agnostic evolution are so many and crucial, requiring of its advocates a boldness of assumption and a baldness of dogmatic assertion, that are anything but sci- entific, gives to the remaining form of the hypothesis — the theistic—o, natural precedence. Even many who are inclined to the other forms of the theory, are constrained, by the in- vincible character of the objections to a purely natural origin of matter and life, to assume a Creator, and so far are to be accounted the- ists, even though, as is the case with some, the Creator is scarcely more than an initial force. Aside from such, it is proper to divide theistic evolutionists into two schools, both of whom hold to a Creator who is not a mere logical abstraction, but a Self-existent, All- powerful, All- wise Personage— a true God. The one supposes creation a single act, which wrought, the Creator is remanded back into the heavens as no longer needed, since the result of creation is so perfect a mechanism as not to require, at any subsequent point, 28 TRUTHS AND UNTRUTHS adjustment, superintendence, or control. We do not dispute the grandeur of this conception, and fully recognize the homage it bestows on the wisdom as well as the might of the Cre- ator. It is, we allow, worthy of an infinite mechanician to construct a machine that will perpetuate itself and never need the interven- tion of its maker. The chief difficulty is, that it fails to adequately explain the facts. The other supposes not only that God created, but that He also governs and controls Plis han- dy work. It holds fast to a Providence, as w r ell as a first cause, believes that God is "the Father Almighty" as well as "the Maker of heaven and earth." This is the only form of the evolution hypothesis, it seems to me, that adequately meets the facts, that has a probability of es- tablishment, and that the Christian can ac- cept. This sees in the history of the universe a process of evolution, but it is one origina- ted and controlled by Divine intelligence and power. It supposes the existence and opera- tion of fixed and unchangeable laws, efficient agents in carrying out the plan of the Great Architect, but they are what they are, and have efficiency, by the ordinance and appoint- ment of the Creator, and He is ever and al- ways co-ordinating and controlling their in- teraction unto the accomplishing of purposed OF EVOLUTION. 29 results. It is, in other words, as Joseph Cook has recently well said, an evolution not by law, but according to law. The advances and discoveries of science have, it may be, overthrown the conceptions of a simultaneous creation of living forms in their maturity; they may have, and we believe they have, made probable that the earth's history — the process by which present existences have received their being and form — has been an evolution; that the development of the individual is a type of that of the sum of human beings; and, in addition, that this evolution has been largely or mainly wrought out by forces or laws inherent in things them- selves. Nevertheless, at the beginning must be supposed a Creator, omnipotent and all- wise; for only thus can be explained the origin and the wondrous adaptations of the universe. Equally, to account for the progressive modi- fications of earth and its inhabitants, the main- tenance of that beneficent equilibrium through which earth has teemed with life and the prog- ress has been upward rather than downward, there is need not only of a Creator, and a cre- ation way back in the beginning, but of a presiding Providence, and creations all along the ages. Certain is it, that again and again something has touched the springs of exist- 30 TRUTHS AND UNTRUTHS. ence and given a new trend to being. It is perhaps impossible to decide, and we do not know that it matters, whether God has done it directly, or through an agency implanted by Him. In either case, it bespeaks Him a living potential Being, presiding over, as well as originating, the universe ; and this, we take it, is the essential fact to be established in the present discussion. So long as one holds on to faith in God, — the Father Almighty pre- siding over and administering the govern- ment of the world, — he is on safe ground. Let evolution be seen to be only an instru- ment or method of God, and it ceases to be antagonistical to faith and religion. As with every hypothesis, so with this, the truth is to be ascertained by the success with which it uni- fies and harmonizes the facts it is propounded to explain. The truths and untruths of evolu- tion, will be exhibited by its success or failure in solving the problems that present them- selves in earth and man, civilization and re- ligion. Into these fields we purpose to press the inquiry. LECTURE SECOND. EVOLUTION AND THE EABTH. In my last lecture I examined the defini- tions and philosophical forms of the evolution hypothesis, pointed out what I conceived to suggest an untruth in the common definitions, and among the philosophical forms, indicated as the only one likely to be established, the theistic, which makes it the expression of the creative wisdom and providential control of that God whom we reverence and worship. The views expressed are now to be tested by application to the facts with which the hy- pothesis has to do. It is plainly vital to any form of the theory which eliminates God, and a controlling intel- ligence from the universe, that its account of origins and its series of causations be complete. It must take in, not only the phenomena of the material world, but of humanity, civilization, morals and religion. It must exhibit and prove a necessary and unintelligent progress 32 TRUTHS AND UNTRUTHS from primordial atoms, up to the highest man- ifestations of human intelligence and morality, — connect by an unbroken gradation of ascent the diatom and infusoria with, a Shakespeare and a Newton, — protoplasm with the phe- nomena of conscience and the ethics of Chris- tianity. A break anywhere in the long chain, the failure anywhere along the line to show a necessary connection, the having at any point to suppose or invoke a determining power out- side of nature, at once makes possible, proba- ble, and perfectly reasonable, the existence of a controlling mind independent of nature, and gives the highest probability to the theory that the entire process from beginning to end is under its direction and efficient control. In this lecture I desire to inquire how sat- isfactorily the existence and present condition of the earth can be accounted for on the theory of materialistic or agnostic evolution. The inquiry is briefly this : — Is it possible to sup- pose our planet, in its past and present con- ditions, the product of causes or forces inher- ent in matter itself, or must we, to account for earth and its contents, predicate some- thing outside of and superior to nature, — a Supreme Intelligence, a Self-determining Will? It has always been the weakness of evolu- tion hypotheses, from the days of Democritus OF EVOLUTION. 33 and Lucretius down to Lamarck and St. Ili- laire, that they failed to give even a plausible explanation of crucial facts. We proceed to inquire whether at the present day the situa- tion has materially changed. The theory of Kant and Laplace as to the method of world-building, known as the neb- ular hypothesis, is the starting point of every modern theory of evolution. This, though yet a mere supposition, serves to bring into unity and scientific correlation so many facts, both of astronomy and geology, that all sci- entists use it as a working hypothesis, and re- gard it as a most probable account of the origin of the solar system and of the earth's structure. The time has long passed when it was regarded as in conflict with revealed re- ligion, and as superseding a Creator. The devout Christian scientist holds to it as firmly, and accepts it as an account of the way God built the world, as freely as the materialist who argues from it that the world need have, and has, no Creator. The fact is, that this, as the theory of evo- lution itself, is and can be interpreted in ac- cordance with either conception. Our con- cern with it is to ascertain, not so much its truthfulness, as whether, if it be true, it affords any countenance to the idea that the world is 34: TRUTHS AND UNTRUTHS self-evolved, — that there has been no inter- ference from without. The nebular hypothesis, as you know, is briefly this: that originally the entire space occupied by the solar system was filled by an evenly diffused nebulous mass of matter. This mass is supposed to possess a slow ro- tary motion. Under the reciprocal attrac- tion of its parts condensation goes on, under which the rotation is accelerated, so that un- der well-known mechanical laws successive rings are formed, and then spheres : thus the planets and their satellites, each moving in the same plane and at proportionate distances, come into being, while the central mass as it contracts gives off light and heat and remains the controlling centre of the system. While this method of world-formation was first proposed as pure hypothesis, and yet re- mains an hypothesis, it so well suits and ex- plains the circular character of the planetary orbits, the plane in which they lie, the uniform directions of their revolutions, and the oblate spheroid shape of the earth, that though there are facts that are yet inexplicable by it, it is gen- erally accepted as the most probable mode by which the solar system came to be what it is. Granting all that is claimed for it, accept- ing it as true, does it make unnecessary an OF EVOLUTION. 35 intelligent Creator and Ruler ? Does it afford the materialistic evolutionist all he needs for a starting point in the long course of unintelli- gent upward progression ? We say nothing here about what must, on his supposition, be potentially present in the fire-mist, in the prim- itive nebulous mass; — the life, intelligence, and consciousness which are manifested in the higher and later stages of the process, which has here its beginning. We do not now press the difficulty of supposing that in this original matter there is " the promise and potency of every form and quality of life." There are sufficiently formidable chasms to be bridged before we come to this. Whence the matter? Whence the force? Whence the relation of the two ? Whence that exact adjustment of materials, motions, interac- tions, and combinations, from which has resulted earth, as habitable and the abode of order, — a cosmos rather than a chaos? At the very beginning of his chain of successive transformations the materialist has to predi- cate matter and force, — and both in definite and fixed amounts. For it is as well estab- lished, as the case admits, that matter and force are each indestructible, and hence are the same in amount to-day as when present in the nebulous mass. From nothing to 36 TRUTHS AND UNTRUTHS matter, — and if force be not a part of matter, from matter to force, — are leaps that are be- yond even the imagination of the materialistic evolutionist. And, therefore, if he may noi accept a creator and a creation, he is shut up to an eternity of both matter, and the source, whatever it be, of its motion. This, if at all conceivable, is only so on the supposition of eternal cyclical changes. The primitive nebula must be regarded as only the debris of former worlds, and the outcome of the evolution now going on will be an ultimate return to primordial atoms. The very postulate of evolution — it being a progression from the simple to the complex, implying alike a starting point and a goal — would seem to sufficiently negative this con- ception. But, beyond this, the evolutionist's own theory of the correlation of forces seems to demonstrate its impossibility. What Sir William Thomson has called " the dissipation of energy " is mathematically proven to be going on continually, so that the sun's heat, the source of energy so far as our system is concerned, is passing out into space, from which it does not return. 1 It can .therefore 1 For a full and clear statement and discussion of this "dissipation of energy," see Newcomb's "Astronomy," pp. 500-505. Also Jevon's "Principles of Science," pp. 441-8. OF EVOLUTION. 37 be predicted that the present constitution of the solar system will not endure forever, — that the time is coming when the sun will be a cold and burnt-out mass, and the mechan- ical energy of the universe will be exhausted. By the very law by which all force is con- vertible into heat, — since that ultimate form of energy is certainly being dissipated, and its entire reconversion into mechanical power is impossible, — it follows that the mechanism will run down and the machine stop, as certainly as a clock, when the weights no longer exert their influence. This necessary end of the process — implying as it does its beginning — negatives, it would seem, the only possible form of the supposition, that mattter and force are eternal. In fact scarcely a single materialistic evolutionist is found who longer claims for them eternity. The thorough-going materialist leaves the problem unsolved, the agnostic places it in the domain of the unknowable, while others admit that here a Creator must be supposed, however well He may be dispensed with in the subsequent process. J. Clerk Maxwell, in article "Atom," Encyclopaedia Britannica, says — "We have reached the utmost limit of our thinking faculties when we have ad- mitted that, because matter cannot be eter- 38 TRUTHS AND UNTRUTHS rial and self-existent, it must have been created." But the proof of a Creator at this starting point i3 not merely a negative one. The fact rests not merely on the dilemma, either eternity or Creation, but is susceptible we think of affirmative demonstration. To constitute a first step in the supposed evolution, force or energy or motion is as ne- cessary as matter, and the two must be in some form co-ordinated one with the other. Besides this, as the amount of matter is a fixed quan- tity, and according to an accepted axiom of science, it has not been and cannot be in- creased or diminished, something outside of itself must have established this amount at the time of its production. A parity of reasoning leads to the conclu- sion that something above itself has meas- ured out and generated the precise amount of energy which would suffice to execute the work to be accomplished. Not only so, — matter exists, we have every reason to believe from chemical science, in elemental atoms, which combine only in cer- tain fixed and definite proportions. These various elements must be supposed to have been present in the original nebulous mass, and that too in definite quantities and pro- OF EVOLUTION. 39 portions, so that not only the total of matter and energy must have been somehow fixed and determined, but equally the amount of each element, and the nature and proportion of their chemical affinities. For instance, there must have been just enough oxygen to combine according to its atomic weight with all the different elements into whose com- position it enters, and leave nothing over. The same is true of hydrogen, carbon, nitro- gen, and all the other elements. The amount of each is just sufficient and no more to make and keep the world the habitable abode it is. Now here is co-ordination that bespeaks design and a designer. At the very begin- ning, when matter was in its simplest forms, when laws as the expression of forces or prop- erties, were fewest, we see the same need of an intelligent mind and ruler, in order to their wise and beneficent collocation and co-ordina- tion, as when the process of differentiation had grown more complex and varied. Indeed, the argument for a first cause, an intelligent Creator, is more unanswerable here than at any other point in the series, for these results, collocations, co-ordinations, cannot be attri- buted to any previous evolution, cannot be claimed as the product of exclusively efficient or necessary mechanical causes, but must be 40 TRUTHS AND UNTRUTHS acknowledged to have constituted a part of the nebulous mass at its origin. And this goes far to conclusively prove that both the matter and its contents, were brought into being and co-ordinated by a supreme and extra-mundane power. Materialistic evolution, therefore, as to the very substance out of which all existing forms are to proceed, fails to give any rational account of its origin. It leaves unanswered the infer- ence that the nebulous mass, its properties and motions, can only be accounted for as the cre- ation of an all- wise and self-existent ruler; that there has been, in other words, a beginning in which God created the heavens and the earth. The only refuge from this conclusion is the remanding of everything, back of the nebulous matter, to the region of the unknowable, leav- ing the origin of all things an-unsolvable mys- tery. Whoevej* accepts a Creator here, by so doing is compelled, it seems to us, to renounce all a 'priori argument against the existence of a power superior to nature, and his subse- quent interference at other and later stages of the process. But granting matter and force — the materials for a mechanical evolution — there is another abyss that must be bridged, or the process cease to be self-sufficient, and that is the chasm which separates dead and living matter. OF EVOLUTION. 41 The introduction of life upon our earth is a problem that presents fully as much and grave difficulty as the origination of matter. And the failure to solve it, is even more fatal to evolution as a necessary, gradual, and con- tinuous process. For it necessitates the inter- position of a supernatural power, a Creator, not merely at the beginning, but midway in the upward progression. Huxley, in his article on " Biology," says: " If the hypothesis of evo- lution be true, living matter must have arisen from not-living; for by the hypothesis, the condition of the globe was at one time such that living matter could not have existed in it, life being completely incompatible with the gaseous state." How necessary such evolution- ists feel it to be, to account for a purely natural or mechanical origin of life, is seen in Helm- holtz's and Sir Wm. Thomson's suggestion that it may have been introduced from a mete- orite. On which supposition Huxley justly ob- serves: — "It makes no difference if we adopt Sir Wm. Thomson's hypothesis, and suppose that the germs of living things have been trans- ported to our globe from some other, seeing that there is as much reason for supposing that all stellar and planetary components of the uni- verse are or have been gaseous, as that the earth has passed through this stage." 42 TRUTHS AND UNTRUTHS Every materialistic evolutionist feels that here is a crucial test, and if their theory is to stand, life must have proceeded out of the not-living. Hence it has been zealously sought to prove the possibility of spontaneous gen- eration, and again and again have we heard that this formidable chasm has been closed. Twice within the past twenty- five years has it been confidently announced that sponta- neous generation, — abiogenesis, — life from the non-living, has been experimentally demon- strated. Pouchet, director of the Museum of Natural History at Rouen, in 1859, and Dr. Bastian in 1870, obtained bacteria and infusorial life from fluids claimed to be entirely freed from every possible living germ. Pasteur repeated, with greater care and scientific accuracy, the exper- iments of the former, and demonstrated that the inference drawn was erroneous, and that life was only present when the germs were introduced from the air, and that where suf- ficient care was taken to obviate this, or suf- ficient heat employed to destroy the germs, life invariably failed to appear. What Pasteur did for Pouchet, Tyndall has done for Dr. Bastian, and to-day there is scarcely an evo- lutionist who does not admit that at present there is no such thing as abiogenesis — that the OF EVOLUTION. 43 sayings, omne vivum ex vivo and omne. vivum ex ovo, "all life from a living germ," express a universal and established fact. Tyndall and all others agree with Huxley in saying, "The properties of living matter distinguish it ab- solutely from all other kinds of things, and the present state of knowledge furnishes us with no link between the living and not-liv- ing"; and also, " The fact is that at the pres- ent moment there is not a shadow of trust- worthy direct evidence that abiogenesis does take place, or has taken place within the pe- riod during which the existence of life on the globe is recorded." 2 The only escape from the inference that life, like matter, was a gift of a living poten- tial Creator, is that offered by Huxley in the addenda to the passage already quoted — "The fact," viz., that there is no evidence that abio- genesis does take place or has taken place, " does not interfere with any conclusion that may be arrived at deductively from other con- siderations that, at some time or other, abio- genesis must have taken place." "The other considerations " reduce themselves, we see from the course of his reasoning, merely to this syllogism : mechanical evolution is established 2 Article "Biology," Encyclopaedia Britannica, Vol. III., pp. 588-596. 44: TRUTHS AND UNTRUTHS by irrefragable proofs; such evolution neces- sitates abiogenesis; therefore, though it is not known to occur now, and has never been known to occur, it must have taken place. Than which I know of no more glaring case of begging the question. To most minds, the concessions that living matter cannot come out of the non-living, and that life only appeared when the globe came to be fitted to maintain it, proves, as far as is possible, its introduction by a power that is not of earth. This is apparently conceded by the one who above all others deserves to be called the fa- ther of modern evolution, — the ldte Charles Darwin. For in his epochal book, — " The Or- igin of Species," — in which he formulates his law of natural selection, he expressly assumes the creation of one or a few low forms of life, and only claims to show how from them all the others have proceeded. Whatever were Darwin's personal beliefs, — and we have rea- son to think he was not disinclined to entirely eliminate God and the supernatural from the universe, — his writings stamp him as a the- istic evolutionist. He no where seeks to ac- count for the origin of matter, or life, or intel- ligence, but only for their development in divergent forms when once existent. of evolution: 45 Notwithstanding this admission, the Dar- winian theory is really the stronghold of ma- terialistic and agnostic evolution, since it is the nearest approach to anything like a plau- sible accounting for the existing forms of the vegetable and animal kingdoms, apart from Divine creation and superintendence. Darwin formulated a law, which evidently has been widely operative in diversifying natural forms, and serves to explain beauti- fully and simply very much that character- izes existing species alike of plants and animals. Mechanical evolutionists hastened, as soon as promulgated, to use it as the mas- ter key that unlocks every mystery and ex- plains every difficulty in their hypothesis, and while to-day abating much in their claims, they yet have to rest upon it as the only formulated cause of the wide diversity in nature. Of such importance is this theory, in its re- lation to the wider theory of evolution, that, at the risk of wearying you by traversing all- too-familiar ground, I must dwell briefly up- on it. The postulates on which it rests are well- nigh axiomatic for their truthfulness. The first is the fact, that the increase of "iving forms on the earth is in a geometrical rat T 'o, 46 TRUTHS AND UNTRUTHS so that in a very few generations the num- ber becomes far in excess of the means for their support. The progeny of a single pair would suffice in a few centuries to overstock the whole earth. As the consequence of such a tendency in plants and animals, there is a struggle for existence, in which the weakest perish, and the strongest survive; by the weakest being meant those least fitted, and by the strongest those best fitted to maintain the struggle. Hence the law is appropriately called "survival of the fittest." Now the fit- ness does not inhere only or chiefly in strength, but rather in adaptation to environment, so that the advantageous peculiarities which enable any particular form to survive are many and varied. It may be physical strength, or some peculiarity of claw or teeth, which makes more certain the capture of its prey, or it may be some defensive adaptation by which a natural enemy is more certainly eluded. The survivors in this struggle are those who possess the peculiarities best fitted to their sur- roundings. Thus far the theory is neces- sarily accepted — its truth is axiomatic. But to make up the law of natural selection, by which the origin of species is to be explained, another postulate is put forth and maintained by Darwin with a wealth and skill of illustra- OF EVOLUTION'. 47 tion and argument, that cannot but call forth admiration. This is the tendency of plants and animals to vary despite the general law of here- dity that like produces like. This is well seen inplantsandanimalsunderdomestication;and by the careful cherishing of desirable varia- tions many new and profitable varieties have been perpetuated. This has been done by human intelligence co-ordinating the laws of heredity and variability. Darwin claims that it is done in nature by the same laws, with- out superintending intelligence, that varia- tions are continually occurring, slight, it may be, but yet sufficient to decide the issue in the severity of the struggle for existence, and where the variation is profitable it secures the survival of its possessor. Thus ever wider and wider variations arise and are perpetuated, and constitute what we call Species. All this occurs, not as the theist claims by a process divinely superintended and governed, but of necessity. From one or a few simple forms of life all the present forms have sprung, through the operation of this law, without intervention or control by God. It was put forth as having universal and unlimited potency. No one doubts that there has been such a thing as natural selection, in the sense that 48 TRUTHS AND UNTRUTHS certain forms, because of inheriting valuable, advantageous peculiarities, have been thereby marked out, selected, fitted to survive; the whole question turns upon how extensively and potentially the law has operated. Is there or is there not a limit to variabil- ity? Does the proposed law suffice for the explanation of all, — as well as of some, — of the past and present diversity of form and function? For more than twenty years the controversy on this point has been waged, and though the final verdict may not have been reached, there are certain conclusions that can be regarded as settled. One is that the potency, whatever it may be, of Darwin's law, is more or less restricted. Alone and by itself it fails at many points to satisfactorily account for crucial facts. As an explanation of necessary evolution it has to be supplemented again and again, and collocated with other and unknown forces and laws. This is conceded on all sides. Darwin, in the fifth edition of "The Origin of Spe- cies," — issued ten years after the first — limits the operation of the law in these words — " I am convinced, ... it has been the most im- portant, but not the exclusive means of modi- fication." He was compelled to invoke new factors to meet its deficiencies, as sexual se- OF EVOLUTION. 49 lection and pangenesis, and then leave much to be accounted for by unknown laws. 3 Alfred R. Wallace, who propounded the principle contemporaneously with Darwin, has always held it as of only limited ap- plicability, and has well pointed out its fail- ure when applied to man. St. George Mivart, of equal rank with Dar- win, Wallace, Huxley and Tyndall as a scien- tist, though an evolutionist, remands natural selection to a subordinative role, and not only asserts, but is generally conceded to prove, that "it requires to be supplemented by the action of some other natural law or laws as yet un- discovered. ' Natural selection ' is insufficient, both on account of the residuary phenomena it fails to explain, and on account of certain other phenomena which seem actually to con- flict with that theory. 1 ' 4 Huxley, whose lucid exposition of the theory served more even than Darwin's labored book to give it popular currency and acceptance, concedes, in the last edition of the Encyclo- pcedia Britannica, "How far 'natural selec- tion' suffices for the production of species re- mains to be seen". . .

XV. 50 TRUTHS AND UNTRUTHS part in the sorting out of varieties into those which are transitory and those which are permanent." . . . "The causes and condi- tions of variation have yet to be thoroughly explored; and the importance of natural se- lection will not be impaired, even if further inquiries should prove that variability is defi- nite, and is determined, in certain directions, rather than in others, by conditions inherent in that which varies." 5 One of the latest important works that has appeared is "The Theories of Darwin," by Eudolph Schmid, in which, in presenting "the present state of the Darwinian theories," the author says (p. 107) — "In summing up all we have said about theories of descent, of evo- lution, and of selection, we still find all the solutions of the scientific problems to be hypotheses, but hypotheses of very different value. The least valuable is the selection theory. It possesses the merit of having started the whole question of the origin of species; it may explain subordinary develop- ments; natural selection may have co-operated as a regulator in the whole progress and the whole preservation of organic life. It seems certain however, according to Ed. Von Hart- s Article "Evolution," Encyc. Brit, Vol. VIII., p. 657. OF EVOLUTION. 51 man, that the impelling principle which called new species into existence lay or originated in the organisms and did not approach from without. This seems to be confirmed more and more decidedly with every new step of exact investigation as well as reflection." These latest conclusions of science as to the insufficiency of Darwin's theory, or " natural selection," to explain the origin of species, these concurrent testimonies as to its having but subordinate efficiency in moulding the forms of life, make it unnecessary to devote more than a casual glance at the points wherein it breaks down. The grounds for denying it the potency at first claimed are chiefly these — 1st. The preponderating evidence is very strong in favor of a limit to the variabil- ity of species, and against the proposition on which the whole Darwinian theory is founded, — that there is no essential differ- ence between varieties and species. The fact that varieties, however they may differ — and in structure they do differ more widely than many species — are universally fertile with each other; and that, in all the wide variation intro- duced by domestication, infertility has not been produced; joined to the fact that species when crossed universally manifest this, the peculiar- 52 TRUTHS AND UNTRUTHS ity of hybridism, combine to prove that there is an essential distinction between the two. This distinction has not yet been broken down, and though the theory has made it ex- ceeding probable that many real varieties are reckoned as species, and the boundaries of true species must be very largely extended, it has not demonstrated that there is no real differ- ence between them. Facts prove, as Huxley concedes, that, coupled with wide morphologi- cal or structural changes, there exists great fixity of physiological or functional character- istics. Indeed, under domestication, a limit is ultimately reached beyond which variation cannot be carried; and it is demonstrable that it is equally so in nature, and that there the limit is much sooner reached. In view of this, the widening of specific limits seems all that can be justly claimed for the theory. If specific modifications have been by descent, as it seems probable that they have been, it has been regulated, not by this but by unformulated laws, and may as well as otherwise have been due to creative power exerted directly on the germs. 2d. The testimony of the geological record opposes the theory in many points. The theory implies not only a general upward gradation in plants and animals, an advance OF EVOLUTION. 53 from the lower to the higher, as we indeed find, but the same advance in particular families or types, which confessedly we do not find; since particular families began ap- parently in their higher rather than their lower members. The theory demands prog- ress by slow gradual modifications; the geological record seems to indicate leaps: many forms of life have appeared suddenly on the scene and unconnected with previous forms. According to the theory there ought to have been many transitional forms; the record affords scarcely any. Those which have been adduced as the assumed progeni- tors of the horse, and winged reptiles, while lending some additional weight perhaps to the theory of evolution, viz., that present forms have been reached by successive modi- fications of previous ones, do not materially strengthen the theory of natural selection. While it still remains an almost insuperable difficulty in that theory, that, in the very strata which afford the most continuous records for the longest periods, there is an entire absence of such forms, as modification by such a law would call for. It is still a fact that the main types of the invertebrates appear almost contemporaneously and without any traceable intermediate forms. 54 TRUTHS AND UNTRUTHS 3d. The enormous lapse of time required for the development of existing species, is, fur- ther, an insuperable bar to its acceptance. Darwin says, "Natural selection acts solely by accumulating slight successive favorable variations; it can produce no great or sudden modification ; it can act only by slow and short steps." 6 Mivart estimates that, by this meth- od, " it would have taken 2,500 million years for the complete development of the whole animal kingdom to its present state." And if natural selection has been the only method, this is not at all excessive in view of the length of time it has taken to differentiate, say the greyhound from the wolf. Now earth, it is mathematically demonstrable, could not, ac- cording to the nebular hypothesis, have been the home of life for more than 100,000,000 years, some estimates say 10,000,000 years, and even the longer period would scarcely suffice for the production of the higher mam- mals. 4th. The theory utterly fails to account for the incipient stages of organs and organisms, which, however profitable in their perfect and mature form, previous to that must have been useless, or even injurious. Mivart, in his " Genesis of Species," has 6 "Origin of Species," p. 421. OF EVOLUTION. 55 fully set forth and illustrated this objection, and shown both the utter impossibility of the acquisition of many peculiarities by any such slow and gradual process, and following Nageli, the mathematical improbability, that a modification, occurring in one or a few in- dividuals surrounded by others, would be perpetuated rather than be lost. These objections are recognized as fatal to Darwin's celebrated theory as a full and satisfactory account of the origin of specific differences. The theory does serve however to explain with much plausibility a number of facts — e. g., rudimentary organs as atrophied through disuse; the phenomena of mimicry, — i. e., close resemblance of certain plants or ani- mals to other and perhaps different plants or animals, as a safeguard from enemies, and hence an advantageous peculiarity certain to be perpetuated ; while it fits in with some of the facts of the geographical and geological distribution of species; of the homology of form and function; and biological develop- ment. We have dwelt thus upon the theory of natural selection, since it is the only one of which science has as yet been able to explain the operation. 56 TRUTHS AND UNTRUTHS The laws with which it has co-operated to effect present diversity are conceded to be unknown, and are merely inferred because there seems evidence that existing forms and species have in some way descended from pre-existent ones. This the present geographical distribution, taken in connection with geological remains, makes most probable. For it is a conceded fact that the geological remains in many cases show the prevalence in geological ages of the same typical forms as are found in the same localities to-day. Thus in Australia is found a particular fauna, and among those peculiar to it, and indeed found nowhere else, are the kangaroos and other pouched beasts, and the same type of creatures is found in its geologi- cal remains. The same fact is true of the very peculiar animals of the sloth and arma- dillo type — found alone in South America. Alfred R. Wallace has collated many cor- roborative illustrations of this feature of geographical distribution, and further shown that the diversity of animals and plants on islands is directly proportionate to the degree of ease with which they can have passed from one to the other. These considerations, with some of those already referred to, as being best explicable on the supposition of OF EVOLUTION. 57 genetic relationship, lend much strength to the hypothesis of an evolution of specific dif- ferences. We have seen that Darwin's theory does not by itself explain them, that there must be supposed other laws, yet unknown and unformulated, supplemental and co-op- erative, to account for the facts. The very fact that different laws have conspired unto the result; that the relation of plants to insects, of many a species to other species, is one of mutual dependence; that the outcome of the struggle for existence has fitted the earth to be a home for man; proves that there must have been a co-ordination and collocation of laws and efficient causes throughout the pro- cess, and this we cannot conceive of, apart from an all-wise and almighty co-ordinator and ruler. Mechanical, necessary evolution fails as signally to explain the origin of species as it does to account for the introduction of life, and the beginning of the world. These all are inexplicable by any other evolution than that which has back of it a living, personal God, creating and governing all things for His own ends; and such evolution, subsequent to its beginnings, differs not from what in theology we call Providence. 58 TRUTHS AND UNTRUTHS In reviewing the ground we have traversed in this lecture, we see that materialistic and agnostic evolution, in seeking to account for the earth and life by causes or forces inherent in itself, is necessitated to bridge the chasms between the non-existent and the existent, between nothing and matter, and matter and force, between the not-living and the living, and between the widely separated forms of vegetable and animal life. We have seen that it fails in each and every instance. We could equally demand of it, to explain still higher steps in the necessary progression. Whence sensation, intelligence, consciousness? By what principle immanent in nature has man, with his reason and conscience, self- determining will and spiritual intuitions, been evolved ? These difficulties are as in- explicable, by such evolution, as those into the consideration of which we have entered. The only rational conclusion, the only con- sistent account of earth and its contents, is an evolution back of which is a creator and a providence in one person. For the origin of matter, of force, of life, of intelligence, of man. — a creator : for the progressive process by which, under laws and secondary causes ordained by the Creator and co-ordinated by Him, earth has become what it is, — a Providence. OF EVOLUTION. 59 True science, when it has traced out the history of the earth and its myriad inhabi- tants, when it has mastered the wondrous connections and intimate relationships of its phenomena, and when, discerning herein the presence of a plan, of thought, intention, pur- pose, it asks the questions, whence ? and why ? will find its only answer to be : — God. LECTURE THIRD. EVOLUTION AND MAN. The advent of man with powers bespeaking a different order of being from any below him, demands even more than the incoming of life, sensation, and intelligence, the interposition of an omniscient and omnipresent Creator; and this is strictly accordant with a divinely co- ordinated and controlled evolution. Mechan- ical evolution, on the contrary, is constrained to make man, as everything below him, the necessary outcome of unconscious and unin- telligent forces, — merely the highest and final product of a slow and constantly ascending natural selection. The Agnostic as much as the Materialist must so regard him. For let it be admitted that man is the Creation of God, and has in his soul something that bespeaks his origin and is akin to his maker, and God ceases to be the altogether unknowable, and the funda- mental postulate of Agnosticism is overthrown. TRUTHS AND UNTRUTHS. 61 Agnostic and Materialist therefore agree in making man only an evolution from the brute, a survival from the same stock as the Anthro- poid Apes. The difficulties however of such a concep- tion are greater than at any previous point in the process. They are such as to cause many an evolu- tionist, as notably Alfred Russell Wallace, to pause, and concede that here mechanical evo- lution fails and that " a Superior Intelligence has guided the development of man in a defi- nite direction and for a definite purpose." However efficient natural selection has been in accounting for the " Origin of Species," many besides Wallace have been constrained to con- cede its inability to explain the "Descent of Man." Wallace's arguments on this point have never yet been satisfactorily met. He urges that natural selection does not account for the size of man's brain, so much in excess of the highest apes, and of his own need when but a slight remove from his brute ances- try. It cannot account for the loss of such useful peculiarities as a hairy covering for his back, and the prehensile character of the feet. Nor can it explain the latent and long unused capabilities of the human hand and voice, and the acquisition of man's character- 62 TRUTHS AND UNTRUTHS istic mental and spiritual faculties. These are difficulties, we may add, not only in the way of natural selection, but of any theory of unin- telligent and mechanical evolution. The hiatus between apes and man is so great as to be a serious stumbling-block in the way of any theory of gradual modification. If man and the ape have had at a remote period a common ancestor, where are the many inter- mediate and transitional forms that must have existed ? It is conceded that man is the latest and possibly the final outcome of the long pro- cess. However far back his advent, compared with the other forms of life, it is recent, and from his first appearance the earth-record is measurably complete. Now this record speaks of no such half men and half apes, as, on such a theory, we have a right to expect. On the contrary the earliest human remains show that man was then no whit less endowed with cranial capacity than the man of to-day. Then as now the size of brain does not perhaps pos- itively decide whether the condition was one of savagery or civilization, but it does pos- itively negative that it was ape-like. To the same purport is the fact, that no man has ever been found so embruted or sunken in savagery as to be without capacity for spiritual quicken- ing and development, a capacity no ape has OF EVOLUTION. 63 ever manifested, and this proves man's intel- ligence to be of a different kind from that of the brutes. In fact it must be granted that if brute instinct be of the same order as hu- man intelligence, then, as Sir John Lubbock justly says, if "anthropoid apes approach nearer to man in bodily structure than do any other animals, it must be admitted that ants have a fair claim to rank next to man in the scale of intelligence." * In view of this, we ask, are we more en- titled to look for the missing link in the do- main between man and the monkey, than between man and the ant? Is it bodily form, or intelligence, that is man's chief char- acteristic ? In either case, however, the chasm is immense and cannot be closed. The evidence is cumulative that serves to disprove the postulate of materialistic and agnostic evolution, that man has been evolved from the brute. Just as to account for matter and force and life a divine interposition is needful, so is it even more essential, in order to account for man, possessed as he is of a soul with moral attributes, and a higher order of intelligence than that of the brutes. There are two inferences necessarily drawn 1 Lubbock's "Ants, Bees, and Wasps, "'p. 1. 64 TRUTHS AND UNTRUTHS from the hypothesis of mechanical evolution that deserve especial consideration, and all the move because it is claimed, that they are estab- lished by independent and positive evidence and hence are put forth as not merely consis- tent with man's descent from the brute, but positive arguments in favor of such an origin. These inferences are: — Maris vast antiquity; and his low primitive condition, only slightly in advance of his supposed brutish ancestry. We readily see, that the establishment of these postulates is essential to the mainte- nance of any theory of mechanical or necessary evolution ; if they be overthrown or weakened by just so much is the entire hypothesis discredited. To the establishment of these propositions therefore have been given great industry of research and wide learning. It becomes us to examine them with great care- fulness and candor. In what remains of this lecture we will consider the question of Maris Antiquity; and reserve for our next, the equally important and closely connected question of his prim- itive condition, — the origin of his civilization. In consistency with the claim that "man is descended from a hairy quadruped, furnished with a tail and pointed ears, probably arboreal in its habits and an inhabitant of the Old OF EVOLUTION. 65 World, and classed among the Quadrumana as surely as would the common and still more ancient progenitor of the Old and New World monkeys," 2 he must be regarded as coining on the stage of earth not only in a condition of savagery lower than any now known, but at a time most remote from the distant period to which the dawn of history carries us back. On the hypothesis of slow gradual modifica- tions, one hundred or even five hundred thou- sand years would not be an excessive estimate of his age on earth, if it be measured by the ratio of his progress in the four or five thou- sand years covered by the records of history. But we will not concern ourselves with this inferential style of reasoning. Fond as the advocates of a great antiquity are of using it, it carries no weight unless mechanical evo- lution itself be accepted, and that too in a form which admits of no modifications or progression except by a process, as slow, gradual and steady, as that by natural selec- tion. To argue antiquity from an assumed progression, at an assumed rate, from sav- agery to civilization, from the ape-like an- cestor, to the cultured descendant, is a mere begging of the question. The issue is capable of being tried in the 2 Darwin's "Descent of Man," Vol. II, p. 372. 66 TRUTHS AND UNTRUTHS light of facts. It is a question of evidence. Do the facts as far as ascertained prove the great antiquity of man ? We will proceed to interrogate the evidences, but before doing so, it may not be amiss to state that latterly there has been in deference to facts, a great curtailing of man's age, from the hundreds of thousands, if not millions of years claimed for it, on the ground that he has become what he is by the slow process of natural selection. Even Ha^ckel has con- ceded that the claims at first advanced were probably excessive, and admits that a modest minimum of twenty .thousand years may prove all that the facts will warrant. E. B. Tylor in his article on " Anthropology " in Encyclo- paedia Britannica, uses equally moderate lan- guage, — as, e. g., "from twenty to one hundred thousand years may fairly be taken as a mini- mum," the evidence of prehistoric remains, requires "an antiquity of at least tens of thousands of years." The development of culture and language " necessitates that to the four or five thousand years to which the ancient civilizations of Egypt, Babylon, and China date back, a probably much greater length of time must be added." This is a marked abbreviation of the hundreds of thou- sands that were at one time claimed. OF EVOLUTION. 67 This bringing down the sojourn of man on earth to somewhere within from double to quadruple the time usually allowed his his- tory is necessitated by any temperate weigh- ing of the facts relied upon to prove his age. Though his advent may be remanded back to a geological period, it is to the period confessedly the topmost of the series. He belongs to Cenozoic time, — the Quarternary age, — the geologically Recent period. There have been frequent announcements that evi- dences of his existence in the Pliocene and even Miocene period of the Tertiary had been found, but more careful examination has ever disproved the claim. So that no recognized authority assigns to man an antiquity older than the Pleistocene of Lyell, and the Middle Quarternary or Recent period of other geol- ogists. There are those who indeed expect the evidence of greater age will be found, but the fact remains that it has not yet been adduced. The sciences to be interrogated as to man's antiquity are three: Geology, Prehistoric Ar- chaeology, and the Science of Culture. And the evidence adduced correspondingly falls under three heads: — 1. Facts which concern the geological position of human remains. 2. Facts which respect man's association, 68 TRUTHS AND UNTRUTHS and contemporaneousness with certain ex- tinct mammals. 3. Facts which respect his race characteristics, diversities of speech, and the origin and growth of civilization. We will as briefly as possible examine the argument. Within the last fifty years, and more par- ticularly the last twenty-five, facts have been multiplying tending to connect man with a past geological epoch, and an extinct fauna. Very few fossilized crania, or bones of man have been found — and such as have been discovered are conceded to have afforded very slight evidence as to his antiquity. Their age as inferable from their posi- tion, rests upon geological considerations, and as to these there is no such agreement as to require the supposition of any very great antiquity. The evidence as to age on the hypothesis of a kinship to the brutes, equally breaks down in respect to the crania that are con- fessedly the most ancient, as notably the Engis and Neanderthal skulls. As to the first, Huxley says: "There is no mark of degradation about any part of its structure. It is in fact a fair average human skull, which might have belonged to a philosopher, or might have contained the thoughtless brain OF EVOLUTION. 69 of a savage." As to the latter, he says, while in some characteristics "the most pithecoid of human crania yet discovered, . . . its ca- pacity may be estimated at about seventy- five inches, which is the average capacity for Polynesian or Hottentot skulls." And "in no sense can it be regarded as the remains of a human being intermediate between men and apes." In the light of these oldest human remains he declares "if any form of the doctrine of progressive development is correct, we must extend by long epochs the most liberal esti- mate that has yet been made of the antiquity of man." 3 The remains of man which are depended on to prove his antiquity and condition, are not his fossilized bones so much as the fruits of his skill and handiwork, which have sur- vived the destruction of time. It is the posi- tion and relations of these indisputable relics of his art, that furnish the principal ground for claiming for him a high antiquity. For instance, mingled with the drift, or val- ley gravels of certain rivers, as the Somme, the Seine, and the Garonne, in France, and the Thames, the Wey and the Ouse in England, 3 Conclusion of Huxle3 T 's "Man's Place in Nature," also Quatrafages' "Natural History of Man," pp. 83-5. 70 TRUTHS AND UNTRUTHS are found worked flints, — the indubitable evi- dence of the existence of man at the period of their deposition. Associated with these tools and weapons of flint, are found the bones of extinct mam- mals, such as the mammoth, the rhinoceros, the hippopotamus, the cave lion and bear, the hyena, etc., etc. Evidences of man's ex- istence and handiwork, are also found in numerous caves in England, Belgium, the south of France, and elsewhere. In nearly all cases his weapons, and tools and pottery, if not his own bones are associated with the same or a similar extinct fauna, as is found in the flint-bearing gravels. Likewise in the peat-bogs, particularly of Denmark, and in what is known as Kjokken Moddings, or kitchen refuse, or shell, heaps, which are numerous and extensive at many points adjacent the sea-coast of northern Eu- rope, are found not only the relics of the shell-fish and animals on which men lived, but many of their weapons and tools, and in such order and arrangement as give us some idea of their condition and mode of life at successive periods. Already at this epoch, however, man has come to have substantially the same eviron- ment as in the historical period, and has passed OF EVOLUTION. 71 out of the geological epoch. The same re- mark applies to the very interesting remains that have been recovered from the beds and shores of the Swiss Lakes, where prehistoric men had for generations as a protection against beasts of prey or hostile tribes of men, their houses built upon piles in the lakes and thus easily isolated from the land. This particular form of dwelling is no evidence of antiquity, as similar structures are found to-day, where among certain tribes considerations of con- venience or security make them desirable, as extensively in the northern parts of South America, and not infrequently elsewhere. In Europe and Asia such structures were in use during the historical period, and are men- tioned by Herodotus in his account of the Ancient P&onians; by Hippocrates, and by other ancient writers. 4 The remains recovered from the sites of the Swiss Lake dwellings, assure us that they were in use from the stone age down to the bronze, yea into the iron, even to the time of the Eoman conquests. The fauna was some of it different from to-day, but none of it geological, 4 As to the use of this form of dwelling iu historic and even present time, see Lubbock's " Prehistoric Man," pp. 174-77. Also Southall's "Recent Origin of Man," pp. 156-58, 178-79. " Epoch of the Mammoth," pp. 40, 58. 72 TRUTHS AND UNTRUTHS or such as to require the assumption of any great antiquity. These several classes of remains furnish all the direct geological or prehistoric evidence there is for man's great antiquity. It remains for us to examine the arguments built upon them, and ascertain whether it is a necessary conclusion that these prehistoric men lived so many thousands of years antecedent to the dawn of history. It is readily granted that man was present in Europe while yet large portions of it were feeling the influence of the last glacier period, that he lived in a climate and among a flora and fauna markedly different from the present, that he carried on the struggle for existence amid difficulties to which his descendants are strangers. We accept this to be the evidence of the river gravels and the caves; though the remains of human art and of the extinct mam- mals have suffered so much of dislocation and mixture by watery currents and other agencies, that the proof of contemporaneousness can be scarcely regarded as conclusive. Dismissing this doubt, however, the question of age turns upon how long a time has been necessary to effect the changes that have taken place. When were the flint-bearing gravels of the rivers deposited? How long, since man was OF EVOLUTION. 73 at least an occasional occupant of the caves, and the contemporary of the mammoth, the reindeer, mid cave bear? How much time must be allowed for the changes in configur- ation of land and in climate that have taken place ? The answer to these questions will depend altogether on the views we take as to the kind and degree of the forces by which these changes have been wrought. The ad- vocates for a very long period, with Sir Chas. Lyell at their head, are without exception uniformitarians, i. e., they assume that geo- logical changes have been wrought by the same forces, not only, as are operating to-day, but by these forces operating in the same way, and with substantially the same energy as at present. It is by this convenient assumption, that, learning the ratio per year or century of any change now going on, the time requisite for the work accomplished can be readily reckoned. Thus Sir Charles Lyell reasons in respect to parts of the shores of Norway. They are found to be rising at the rate of say two feet and a half in a century, therefore where they have been upheaved to an altitude of six hundred feet it must have required a period of twenty- four thousand years. So too the time it has taken to form the alluvial shores and the 74 TRUTHS AND UNTRUTHS delta of the Mississippi, or the Nile, may be calculated by ascertaining the amount of sedi- ment that is each year carried down by their waters, and dividing by it the alluvial mass; thus assuming the delta of the Nile, for exam- ple, to have grown at the rate of three inches and a half in a century, it would have taken several hundred centuries to have accumulated the many feet that make up its present thick- ness. On the same principle, Huxley assigns ten thousand years, and others three to four times as many, as necessary to have produced the gorge below Niagara Falls. The mighty rush of water is cutting away the rock at the rate of from one to three feet per year: it is therefore a simple mathematical calculation to ascertain how long it has taken to wear away the six miles of ravine that lie below the present Falls. It is by calculations such as these that the date of the river-gravel and cave men is sought to be ascertained. As to the flint implements of the Somme Valley, their age is calculated by estimating how long it must have taken for the beds of gravel rising from the chalk fully one hun- dred feet in places, to have been formed, on the supposition that every change has been wrought by the agency of the present river, OF EVOLUTION. 75 flowing indeed at a higher level and with some greater volume, but in other respects no more potent to work changes than at present. The calculation begins by estimating the age of a deposit of peat about thirty feet in thick- ness, which overlays, and is more recent than, the gravel. The age of this has been com- puted in this way. At about eighteen inches from the surface have been found several flat dishes of Roman pottery, from which it is inferred that the peat has only grown about eighteen inches in perhaps eighteen hundred years, at which ratio of deposition the age of the whole thirty feet cannot be less than three to four hundred centuries. This conclusion led even Sir Charles Lyell to hesitate to adopt the proposed rate as a true chronometric scale. But it is precisely on this principle that such calculations are made. If a valley has been worn down, it has been at an average erosion of so many feet a century; if the coast line has sunken, it has been at a given ratio of de- pression ; if peat has formed, it has been at a fixed rate; and as all these .features are pres- ent in the Somme Valley it must have re- quired so many millenniums to have brought it to its present condition out of the original chalk. This is manifestly assuming that the forces of nature operate with a uniform ratio 76 TRUTHS AND UNTRUTHS of intensity. Without pausing at this point to controvert the postulate, we may further observe that the age of the cave men in many cases is ascertained in the same way. An instance is found in connection with the famous Kent cavern of England. Beneath a deposit of stalagmite five feet thick were found flint implements and the ashes and coals of a fire. At once a time measure was sought, and it seemed ready at hand, for two hundred and twenty years ago a man had carved his name upon the stalag- mite, since which time it had grown only one-eighth of an inch, hence to form the five feet must have required a period of one hun- dred and twenty thousand years, and a prom- inent lecturer from England claimed before an American audience only a few years ago, that on this evidence we must believe the man or men who built that fire in Kent cave did it more than a hundred thousand years ago. Such results it would seem must necessarily cast suspicion on the methods by which they are reached. We have only instanced one or two of the many applications of this principle of uniformity as the basis for an estimate of time. The occasion does not admit or require that I should do more. All such estimates are utterly worthless, since nothing is capable OF EVOLUTION. 77 of more triumphant demonstration than the very converse of the assumed principle. There is no such thing in nature as the as- sumed indefinitely continued uniform activity of its forces. It may be on the contrary laid down as a law, that the forces of nature have no uniform ratio of activity. Peat is forming to-day as it has in the past, at nearly every rate of growth, from one foot a century to one foot a year, and how long it has taken any particular deposit to form can- not be calculated on the assumption that every part has growth at the same rate. This is equally true of stalagmite: it may grow as slowly as the case cited, one-eighth of an inch in two hundred and twenty years; it has been known to form as rapidly as one- eighth of an inch in six months; and because at one period the deposition is very slow, it by no means follows that at another and earlier it may not have been very rapid. The same is true of those wider and more exten- sive changes which respect the elevation, or depression of land, carrying with them as they necessarily do important changes of climate and corresponding variations of flora and fauna. These are not, any more than the other and minor modifications, made at a 78 TRUTHS AND UNTRUTHS uniform rate. A coast line may rise for a century at the rate of only a few inches or feet in all that time; it may also rise or sink suddenly, as has happened to the coasts of India and South America; or again, in the period of a single generation it may undergo most marked changes, such as Darwin notes as having oc- curred in Chili 5 or as are now taking place in Hudson's Bay, whose shores have risen several feet in the memory of man. And the fact that change has been going on for a century at one rate, is no criterion for judging what the rate will be in the century to come or what it has been in centuries past. The pres- ent popular school of Uniform itarian geology, founded by the lamented Lyell, was a natural and proper reaction from the Cataclysmal theories that had obscured the important dy- namic effects wrought by long continued action of existing forces. But just as the day of accounting by sweeping catastrophes for every geological change is past, so we believe will it soon be with rigid Uniformitarianism. The one extreme is as far from the truth as the other. Other agencies have operated in nature than those we see at work every day. And moreover, these ordinary agencies and forces 5 See "Voyage of a Naturalist," p. 310, OF EVOLUTION. 79 have wrought on a wider scale and with a greater energy than we ordinarily observe. Thus have changes, we doubt not, been many times wrought more extensively and rapidly than is conceivable on the uniformitarian hypothesis. Besides, uniformity itself is cumulative, and accumulations of slight changes tend neces- sarily and invariably to catastrophes. It may take a long period for such accumu- lations to overthrow the equilibrium, but the time necessarily comes when there must be a readjustment. Then the changes are so rapid as to be cataclysmal, and a very brief space may suffice to work fundamental and revolu- tionizing effects. It is such catastrophes as these, that are perchance centuries in preparing and other centuries in working out their effects — catas- trophes which are readjustments made neces- sary by changed conditions, that are lost sight of by geologists of the Lyell school. The fact that uniform conditions exist and have been observed for long periods, af- fords no basis for predicting the length of their continuance, or fixing the date of their beginning. Who would be prepared in view of the uniformity in the contraction and ex- pansion of water under the wide range of 80 TRUTHS AND UNTRUTHS degrees of heat marked by 40° to 200° for, the changes that take place when 32° is reached on the one side, and 212° on the other? Yet something similar to this is to be looked for throughout the whole domain of nature. Uniformity necessarily tends to its own overthrow. When catastrophes are spoken of and their agency invoked to ex- plain natural phenomena, thought naturally reverts to such as earthquakes, volcanoes, tidal waves, and the like, which come seem- ingly by no law and most unexpectedly. The very fact that such unpredictable events can interpose and work wide-reaching effects, make more or less uncertain the estimates based on rigid uniformity. But these are not the kind of catastrophes that have been most potential and widely revolutionizing in their effects, but rather such as by their cul- mination have brought increasing cold and glacieration unto the changing the climate and life of extensive regions, and those which in turn destroyed the glaciers, and gave more favorable conditions to vegetable and animal life. In such wide reaching changes, though the causes leading up to the event may have acted slowly and uni- formly, there must be conceived to have been an acceleration of rate as the crisis OF EVOLUTION. 81 approached, and with it a more intense and rapid action of all the forces. The avalanche, for example, is prepared for by each increase of snow and ice, — and as certainly as the mass grows, so certainly will the law of gravity cause a portion some day to be launched on its destructive course, but no one can predict the time, or measure the rapidity or extent of the changes, by the rate of growth that produced the needful con- ditions. 6 Whatever were the cause or causes of the glacier period we may be sure the nearer it came to its culmination, the more intensely they operated. And what- ever causes produced the increase of heat which melted them, we may be certain that each season brought a more and more rapid wasting of the accumulated ice, and a cor- responding amelioration of climate, until an equilibrium was reached. The position of the earlier remains of human 6 I cite the Avalanche as an illustration of this sort of cataclysmal change, since however circumscribed may be its effects, the catastrophe is prepared for by a gradual process, and is followed by changes which however rapid and extensive at first, become finally slow and gradual. What we would emphasize is that many of the greatest and most influential changes in nature are of a similar character— catastrophical— preceded and followed by long periods of slow and gradual modifications. 82 TRUTHS AND UNTRUTHS art and their juxtaposition to the members of a fauna indicative of an almost arctic tempera- ture, goes far to prove that man had his home in Southern Europe at a period when the glacier system was with increasing rapidity passing away. The phenomena can only be explained on some such catastrophical theory as we are advocating. The very length of time required on the rate of change assumed by the rigid Uniformitarian is in itself a dis- proof of the theory. The men of the river- gravels and the caves would seem to have been destroyed or driven away by just such floods as must have occurred in the more and more rapid melting of the glaciers. Every- thing in the situation, character and rela- tions, of the remains, suggest a sudden — if what may have taken a century or two, may be called sudden — change in climatic conditions. The most probable explanation of this change supposes along with the depression of the cen- ter and south of Europe, an elevation of both. Northern Asia and Africa — converting on. either side of the glacier-capped mountains' of Europe, what had been land-locked seas, into denuded plains. The effect on the north was a lowering of the temperature of Northern Europe and Asia, and the transference of the OF EVOLUTION. 83 belt of perpetual ice further north. While on the south the effect was the drying of the inland sea of Africa, — the converting it into the heated waste of sand, known as the Sahara, and this not only took away the most abun- dant source for the precipitation that fed the glaciers, but furnished the heated winds that caused them to melt so rapidly, that the rivers must be conceived as having fully a hundred- fold the volume and force of to-day. The more such a catastrophe as this is made probable and well-nigh certain, the more likely does it become that its effects would be most wide- reaching, and abandoning the Uniformitari- an's disproven method of reckoning, we can believe it need not have been more dis- tant in time, than that deluge of which nearly every race and language retains the tradition. Whether this be so or not, cer- tain is it, that time backward cannot be computed on the principle of rigid uniformity of the operation of nature's forces. And with this method of calculating time done away, the grounds on the score of geology and prehistoric archaeology for claiming for man a vast antiquity also fail. The extinct animals among whom he lived give, we further see, no criterion of age, be- cause they themselves are old or not, just as we 84 TRUTHS AND UNTRUTHS determine the probable cause of their extinction. If, as is most probable, they were destroyed as much before the changes of climate, and the flooded condition of their habitat, as the weap- ons of man or the struggle with other beasts, the same events that buried the evidences of man's presence swept them away, and contem- poraneousness with them does not add a cen- tury to the age of man. This is strongly confirmed by the structural condition in which many of these remains are found. Very many have even to-day more of the structure of bone, than stone. This is es- pecially noticeable in the numerous remains of the mammoth in Russia; where, preserved by frost, specimens have been found so per- fect as to give an almost complete idea of its appearance and habits. Indeed, there it is plain, that a sudden destruction overtook whole herds of these massive mammals, and that, at no extravagantly remote period. And the fact that sudden glacieration de- stroyed them, favors, very decidedly, the hy- pothesis, as to the causes which destroyed the glaciers of central Europe, referred to above. In considering the facts deduced from the ancientness of race peculiarities, and diversity of language, — the science of Culture, — in their bearing on man's antiquity, we have need to OF EVOLUTION. 85 invoke the same principle we have been con- sidering. Quiet and slow as are nature's forces when in equilibrium, they act violently and rapidly when the equilibrium is disturbed, — when they are seeking a new adjustment. We are ignorant of the causes that produced the original divergence alike in races and speech, but there seems little doubt in the light of all analogy that whatever they were, the limit of divergence was, within a short period, reached. Since then the environment and the nature responsive thereto, have re- mained so constant, and the causes likely to produce change have been so few and slight during the whole historical period, that the principal types alike of races and language have remained substantially fixed. If this be correct, then the argument for a long antiquity in order for man to differentiate his form, and color, and speech and arts by slow and gradual steps, is completely done away. Probably the very same cataclysm that so radically changed the climate, the flora and the fauna, of man's dwelling places, may have started the train of causes that has given us the races of men and led to the con- fusion of their tongues. The geological strata in their breaks, upheavals, convolutions, etc., as well as in their proofs of sudden transforma- 86 TRUTHS AND UNTRUTHS tions of life, — extensive destructions of old forms and the incoming of new ones — afford evidence that if these changes were brought about by existing forces, they were operating far more widely, energetically and rapidly than now. They could not have been wrought by a law like natural selection or survival of the fittest, which only admits of slow and almost imperceptible modifications. Clarence King did good service a few years since in showing this, as to our American continent, particularly with reference to the more recent geological ages. There is even stronger evidence of the same fact as to the fields in Southern and West- ern Europe in which the remains of prehis- toric man are found. He had to. struggle with, and flee from, if not succumb before, a rapidly and catastrophically changing envir- onment. The weakness of the argument for a great antiquity, drawn from a changed fauna, and the time requisite to develop a high civiliza- tion in the same territory where savagery has prevailed will be apparent, if we suppose, the history of our own country were lost, and had to be reconstructed from the material with which Archa3ologists have to work. If there were no other data but those mark- ing the contrast between the present evidences OF EVOLUTION. 87 of an advanced civilization, and the arrow- heads and flint implements dug up in our fields and gathered in our museums, the tokens of a pre-existent savagery, together with the de- crease verging to extinction of a fauna natural to a savage social condition, the inference would be drawn that an enormous length of time must have elapsed in order to so great and radical a change. According to the reas- oning of Lubbock, Tylor, and others, the num- ber of years necessary to work such changes, for the stone age to develop into the bronze, and the bronze into the iron, for the old fauna to yield to one substantially new, would on the hypothesis of slow, gradual modification, be numbered by the hundred thousands. Yet in the light of history we know that most of these changes have been wrought in a single century, and all have required less than three hundred years. A careful weighing of the evidence leads us to the conclusion that man's antiquity is far less than has been claimed. We deem it certain that he has not been a denizen of earth for the period that must be allowed on the supposition of nothing but slow and uniform rates of change in himself and his surroundings. His antiquity we can safely say is not such 88 TRUTHS AND UNTRUTHS. as to support the hypothesis of mechanical, ■unintelligent evolution. In our next lecture we shall endeavor to 'show that equally there is no good or valid ground for the assertion that man was origi- nally a brute-like savage. LECTURE IV. EVOLUTION AND CIVILIZATION. In support of a necessary evolution, inclu- sive of man and everything below him, much attention has been given to the proving that his origin was back in dim geological time, and that his original condition was far below that of any known savages. Both these postu- lates are necessary to the hypothesis sought to be proven. For while the establishment of both would not weaken the objections on other grounds to mechanical evolution, or favor it, more than the supposition that an intelligent Supreme Being has begun in Creation and has guided by Providence, whatever evolution there has been; we readily see that the failure to establish either of them is fatal to any theory of necessary evolution as accounting for man's origin and progress. In our last lecture we briefly presented some 90 TRUTHS AND UNTRUTHS of the arguments against accounting for man as an evolution from the brutes, and then ex- amined the claim as to his antiquity. We found that the claim rested on an unproved and improbable theory of uniformitarianism in nature's operations. That the facts ad- duced proved indeed extensive and radical changes of land, and water, and climate, of vegetation, animal life and man, but that such changes could as well have been ef- fected in one millennium as a hundred, and did not probably antedate the historical pe- riod more than, if as much as, a thousand years. We now turn our attention to the other postulate, that man at his origin was but a slight advance over the brute, and that he has risen by slight and progressive modi- fications from an ape-like savage to his high- est present condition. He must be supposed, without intervention from a Divine Maker or Ruler, to have ac- quired his speech, his arts, his morals, his religion; and to have passed from the lowest manifestation of each to the highest, by a principle of progression inherent in himself, or imposed by his environment. Of course if this could be proven, if man has come to be what he is by a process as slow and gradual as that of natural selection, OF EVOLUTION. 91 it would be a strong presumption in favor of man's claimed antiquity. In fact this is the argument principally urged and relied upon to establish that fact. This is the argument for man's hoary anti- quity deduced from the science of culture, to which in our last lecture we scarcely more than alluded. We then deferred its discus- sion, because a full reply to it turns upon the questions we are now to consider: viz., Whether man ivas originally as brute-like as is claimed? And by ivhat process has he become what he is, in his most civilized condition ? These questions are to be answered, not by the "it may be supposed" and "we may readily conceive " style of argument which is so fre- quently employed by the advocates of an un- intelligent evolution, but by a careful weigh- ing of evidence, an appeal to facts. If man has descended from the brutes, if he has as- cended from an ape-like savage, it is to be properly decided only by an examination of his oldest remains, the study of his earliest records. Now the first question to be asked is, where are these to be found? Assuredly, at the original home of the race, — the cen- ter from whence he has radiated. For the evolutionist holds as most accordant with 92 TRUTHS AND UNTRUTHS his theory, what is otherwise most proba- ble, the unity of the human family, and if the diverse races have descended from a com- mon ancestry, there must have been some- where an original central home. It is the concurrent opinion of nearly all ethnologists that this home was somewhere on the great plateaux of Central Asia, and that from thence man has migrated or extended unto the va- rious habitable portions of the globe. Now, it will be conceded that the evidences thus far adduced for savagery, and an originally low type of humanity, have not been gathered in these the earliest seats of man and his works. On the contrary, they have been col- lated from what must have been, supposing the opinions of ethnologists to be correct, the very outposts of population, from the scenes of migrations most distant from the original centres. The study of the so-called "prehis- toric man" has thus far been chiefly confined to his European habitat. The classification of men according to the materials used in meeting their necessities, — the division of prehistoric times into Ages of Stone, Bronze and Iron, is based on what has been learned respecting man, as he has lived and wrought in Western Europe, in Denmark, Belgium, France, Switzerland, and Great Britain. Sir OF EVOLUTION. 93 John Lubbock in his interesting and authori- tative work on "Prehistoric Times" (p. 2) says: "In order to prevent misapprehension, it may be well to state at once, that for the present, I only apply this classification to Europe, though in all probability it might be extended also to the neighboring regions of Asia and Africa." Should we concede all that is claimed respecting the successive pe- riods through which man is supposed to have lived in Europe, there is absolutely nothing presented to show that his lowest and rudest condition there, was not contemporaneous with not only a higher, but an exceedingly high civilization, in the older homes of the race. In fact the evidence is entirely want- ing of a stone age, not only in the supposed original seat of man, but in the countries ear- liest settled. In the valleys of the Euphra- tes and the Nile, where archaeology has pur- sued its investigations most thoroughly, that which is earliest in time is usually found the fullest of evidence as to the skill and ability of artisan and builder. As far back as we are able to go in the antiquities of Egypt, and Babylon, of Persia, India and China, we are able to discern no inferiority in man, his works or his civilization. His achievements bespeak him the peer of his descendants. If his first 94 TRUTHS AND UNTRUTHS exercises of skill, his first attempts in the arts were with stone, he so soon passed beyond it and out of its limitations, that there are no such relics or remains of stone weapons or implements, as would suggest a time when their use was general. 1 What prehistoric archaeologists are fond of terming "primitive men" " the oldest known types of humanity," are by no means likely to have been really such, since they are found just where, and only where we would expect to find the strays and exiles from the ancient home, and amid surroundings that made the struggle of life most severe. Hence to find rudeness of art, and inferior civilization, yea, savagery here, would tell nothing as to what might have been the condition at the same time in the older abodes of men. Bearing in mind that the facts we are to consider refer not necessa- rily to primitive man, but only to the earliest inhabitant of Western Europe, let us examine into their significance as showing his original condition, and the successive steps of his up- ward progress. It is conceded by all that the men of the 1 Implements and weapons of stone are found in Egypt and Babylonia, but not under such circumstances as to in- dicate exclusive use, or a ".s/one
