 DEAR SIR, 
 
 XTOTWITHSTANDING my unwilling- 
 -** ^" nefs to engage any farther in metaphy- 
 lical controverfy, there are fome circumftan- 
 ces attending your Obfervatioru on my Yreatife 
 on Pbilofopbical Neceffity, that make me in 
 this cafe lefs averfe to it. You are an old 
 acquaintance, whom I refpect, and whom I 
 believe to be aduated by the beft views ; you 
 are thought to be a mafter of this fubjedt, 
 and have certainly given very particular at- 
 tention to it j thinking, as I myfelf do, that

 it is of the greater! importance ; and now, in 
 a work of confiderable extent, you confine 
 your obfervations to it. 
 
 Your publication has alfo been a work of 
 great expectation among our common friends, 
 who were apprized of your intentions. By 
 yoUr own account, in your Preface, it muft 
 have been compofed more than a year ago. 
 In this time it has been fubmitted to the 
 perulal of perfons of great learning and 
 worth, who, I am informed, think highly of 
 it, and have recommended the publication, 
 not only as excellent in itfelf, but as very 
 proper to follow that of Dr. Price, who was 
 thought by them to have been too tender of 
 me, in our amicable difcuffion, and to have 
 made fome imprudent conceffions. Your 
 work, it. is thought, will fupply the defici- 
 ency in his. 
 
 You had the generofity to propofe fubmit- 
 ting your work to my own private perufal ; 
 and though, for reafons of delicacy and pro- 
 priety,
 
 DOCTRINE OF NECESSITY. 3 
 
 priety, I thought proper to decline it, I en- 
 couraged you in your defign of publication. 
 Alfo, though I did not, I believe, make you 
 any particular promife, you will probably ex- 
 ped: that, all things confidered, I mall give 
 you an anfwer. I therefore do it, and with 
 the fame freedom with which you yourfelf 
 have written. But, I mail confine myfelf 
 chiefly to the difcuffion of thofe points on 
 which the real merits of the queftion turn, with- 
 out replying at large to what you have ad- 
 vanced with refpedt to the conferences of the 
 doctrine. Indeed, if the doctrine itfelf be 
 true, we muft take all the genuine confequen- 
 ces, whether we relifh them or not. I pro- 
 ceed, therefore, to a ftate of the controverfy 
 between us, and the confideration of the na- 
 ture and weight of what you urge with re- 
 fped: to it. 
 
 principal argument for the doctrine of 
 Neceffity is briefly this : If, in two precifely 
 equal filiations of mind, with refpecT: both to 
 difpofition and motives, two different deter- 
 6 2 minations
 
 4 A DEFENCE OF THE 
 
 minations of the will be poflible, one of them 
 muft be an effect without a caufe. Confe- 
 
 quently, only one of them is poflible.^ 
 
 . 
 
 Now all that the ingenuity of man can re- 
 ply to this is, either that, though the deter- 
 mination be uncertain, or contingent (de- 
 pending neither upon the previous difpofition 
 of mind, nor the motives prefented to it) it 
 will {till, on fome account or other, not pro- 
 perly be an eff'eft without a caufe. For that 
 there can be any effecT: without a caufe, no 
 advocate for the doctrine of liberty has, I be- 
 lieve, ever afTerted. Or, in the next place, it 
 may be faid, that the above is not a fair flating 
 of the queftion in debate ; for that the deter- 
 minations may be invariably the fame in the 
 fame circumftances, being agreeable to fome 
 conftant law or rule, and yet, not being necef- 
 farily fo, the necefTarian, in facl, gains no ad- 
 vantage by the conceffion. 
 
 You, Sir, have combated the neceffarians on 
 both thefe grounds ; maintaining that what- 
 ever
 
 DOCTRINE OF NECESSITY. 5 
 
 ever be the ftate of mind, or the motives pre- 
 fent to it, it has within itfelf a power of de- 
 termining without any regard to them, the 
 f elf- deter mining power being itfelf the proper 
 caufe of the determination. You likewife af- 
 fert that, though there mould be the greateft 
 certainty in all the determinations of the will, 
 yet becaufe it is not Kphyfical, but only a mo- 
 ral certainty, it is not a proper neceffity. I 
 mail confider diftindtly what you have ad- 
 vanced on both thefe views of the fubject, in 
 the order in which J have mentioned them. 
 
 B 3 SECTION I,
 
 A DEFENCE OF THE 
 
 SECTION I. 
 
 Of the Argument for the Dottrine of Neceffity 
 from the Confederation of the Nature of Caufe 
 and Effeft. 
 
 "TN the very fame circumftances," you fay, 
 * p. 17, " in which the choice or deter- 
 " mination was directed to one objedl of pur- 
 " fuit, it might have brought itfelf to will, or 
 " determine on the purfuit of a different, or 
 " contrary one. In other words, the mind 
 " is free to deliberate upon, and, in confe- 
 " quence of this, to chufe, and determine the 
 " motives of its condudt." 
 
 This ftate of the cafe, I would obferve in 
 the firft place, evidently implies that the mind 
 cannot determine itfelf without fome motive; 
 but you think that, becaufe it is capable of 
 
 deliberating
 
 DOCTRINE OF NECESSITY, 7 
 
 deliberating upon motives, it can chufe what 
 motive it will be determined by. But if the 
 mind cannot finally determine without a mo- 
 tive, neither, furely, can it deliberate, that is, 
 determine to deliberate, without a motive. Be- 
 caufe the volition to deliberate cannot be of a 
 different nature from the volition that is con- 
 fequent to the deliberation. A volition, or 
 a decifion of the mind, by whatever name it 
 be denominated, or whatever be its nature, 
 muft be one and the fame thing. It muft, in 
 all cafes, be fubjecl: to the fame rule, if it be 
 fubje<fl to rule, or elfe be equally fubjecl: to 
 no rule at all. You had better, therefore, fay 
 at once, that every determination of the mind, 
 even the final one, may proceed on no mo- 
 tive at all. And your next retreat will equally 
 ferve you here : for you {till maintain that, 
 though there be nothing, either in the difpo- 
 fition of mind, or the motives prefent to it, 
 that was at all the caufe of the determination, 
 it will not be an efFe<ft without a caufe, be- 
 caufe the felf-determining power is, itfelf, a 
 proper and adequate caufe. 
 
 B 4 " There
 
 8 A DEFENCE OF THE 
 
 " There remains a proper caufe," you fay, 
 " p. 24, a fufficient and adequate caufe, for 
 " every volition or determination which is 
 " formed. This caufe is that felf-determin- 
 " ing power, which is eflential to agency, and 
 " in the exercife of which motion begins." 
 Again, p. 36, " One principle of freedom in 
 " the human mind will fufficiently account 
 " for all their actions, and to feek after other 
 " caufes, muft, therefore, in his own way of 
 " reafoning, be wholly unneceffary." 
 
 Now to every thing that can be advanced 
 to this purpofe, I think I have given a fatis- 
 factory reply in the additional illuftrations, 
 printed in my Correfpondence with Dr. Price, 
 p. 288, in which I mew that the felf-deter- 
 mining power, bearing an equal relation to 
 any two different decifions, cannot be faid to 
 be a proper and adequate caufe with refpedt 
 to them both. But this fection, I fuppofe, 
 you muft have overlooked, otherwife you 
 could not but have thought it peculiarly ne- 
 ceflary to reply to my obfervations on that 
 
 fubject,
 
 DOCTRINE OF NECESSITY. 9 
 
 fubject, which fo very materially affect your 
 argument. I muft, therefore, take the liberty 
 to requeft that you would confider it, and re- 
 ply to it. 
 
 To argue as you do here, in any other cafe, 
 would be thought very extraordinary. If I 
 afk the caufe of what is called the 'wind, it is 
 a fufficient anfwer to fay, in the firft inftance, 
 that it is caufed by the motion of the air, and 
 this by its partial rarefaction, &c. &c. &c. ; 
 but if I afk why it blows north rather than 
 fouthy will it be fufficient to fay that, this is 
 caufed by the motion of the air ? The mo- 
 tion of the air being equally concerned in 
 north and fouth winds, can never be deemed 
 an adequate caufe of one of them in preference 
 to the other. 
 
 In like manner, the felf-determining power, 
 allowing that man has fuch a thing, and that 
 it may be the caufe of determining in general, 
 can never be deemed a fufficient caufe of any 
 one particular determination, in preference to 
 
 another.
 
 10 A DEFENCE OF THE 
 
 another. Suppofing, therefore, two determi- 
 nations to be poffible, and there be nothing 
 but the mere felf-determining power to de- 
 cide between them, the difpofition of mind 
 and motives being all exactly equal, one of 
 them muft want a proper caufe, juft as much 
 as the north or the fouth wind would be 
 without a proper caufe, if nothing could be 
 affigned but the motion of the air in general, 
 without fomething to determine why it mould 
 move this way rather than that. 
 
 Befides, abftractedly and ftrictly fpeaking, 
 no mere power can ever be faid to be an ade- 
 quate caufe of its own acts. It is true that 
 no effect can be produced without a power 
 capable of producing it ; but power, univer- 
 fally, requires both objetts and proper circum- 
 Jlances. What, for inftance, can be done with 
 a power of burning, without fomething to 
 burn, and this being placed within its fphere 
 of action ? What is a power of thinking, or 
 judging, without ideas, or objects, to think 
 and form a judgment upon ? What, there- 
 fore,
 
 DOCTRINE OF NECESSITY. II 
 
 fore, can be done with a power of 'willing, 
 without fomething to call it forth ? and it is 
 impoffible to ftate any cafe in which it can 
 be called forth, without implying fuch circum- 
 Jiances, as will come under the defcription of 
 motives, or reafom for its being exerted one 
 way rather than another, exactly fimilar to 
 any other power, that is, power univerfally and 
 abftrattedly conjidered, corporeal or intellec- 
 tual, &c. &c. &c. 
 
 SECTION II. 
 
 How far the Arguments for the "Doffirine of 
 Necejfity are offered by tlie Conjideration- of 
 the Soul being material or immaterial. 
 
 T> UT you have another refource befides that 
 *~* which I have confidered in the prece- 
 ding fedtion j which is, that though it be true 
 that, fuppofmg the foul to be material, and 
 fubjeft to phylical laws, every determination 
 requires a foreign caufe, yet if the foul be im- 
 material,
 
 12 A DEFENCE OF THE 
 
 material) no fuch caufe is necefTary. It may 
 then determine itfelf in whatever manner it 
 pleafes. 
 
 " The whole of it" (viz. the fedion con- 
 cerning the argument from caufe and effecl:) 
 you fay, p. 20, " fuppofes a fimilarity in the 
 " conftituent principles of matter and fpirit; 
 " for by thofe only who confefs that fimila- 
 " rity, will it be acknowledged that the fame 
 " general maxims will apply, both to effeds 
 " mechanically produced, and thofe which 
 ' depend upon will and choice." Again, you 
 fay, p. 22, " To a principle of thought con- 
 " ceived to be material, a change of circum- 
 <c fiances may be effential to a difference of 
 " volition ; but when the mind is conlidered 
 " as being in its own nature immaterial, and 
 " therefore not fubjedt to the laws of matter, 
 " but as endued with a felf-determining pow- 
 " er, a variety of volition or determination 
 " in the fame fituation or circumftances may 
 " be admitted as poffible, without any contra* 
 " didlion, or feeming difficulty at all." 
 
 Now
 
 DOCTRINE OF NECESSITY. 13 
 
 Now I really cannot conceive that the con- 
 tradiction is at all the lefs glaring, or the dif- 
 ficulty more furmountable, on the hypothecs 
 of the mind being immaterial. It does, in- 
 deed, follow that the mind, being immaterial, 
 is not fubjecl: to the laws of matter j but it 
 does not, therefore, follow that it is fubjecl to 
 no laws at all, and confequently has a felf- de- 
 termining power, independent of all laws, "or 
 rule of its determinations. In fact, there is 
 the very fame reafon to conclude that the mind 
 is fubjecl: to laws as the body. Perception, 
 judgment, and the pajfions, you allow to be fo, 
 why then mould the will be exempt from all 
 law ? Do not perception, judgment, and the 
 paflions, belong to the mind, jufl as much as 
 the will 5 yet, notwithstanding this, it is only 
 in certain cafes that the powers of perception, 
 judgment, or the paffions, can be exerted.; 
 Admitting the mind, therefore, to be imma- 
 terial, it may only be in certain cafes that a 
 determination of the will can take place. You 
 muft find fome other fubftance to which the 
 will is to be afcribed, entirely different from 
 
 that
 
 14 A DEFENCE OF THE 
 
 that in which perception and judgment inhere, 
 before you can conclude that its affections and 
 acts are not invariable, and even necefiary. 
 
 Befides, according to all appcarances y from 
 which alone we can be authorized to conclude 
 any thing, the decifions of the will as invari- 
 ably follow the difpofition of mind, and the 
 motives, as the perception follows the prefen- 
 tation of a proper object, or the judgment fol- 
 lows the perceived agreement or difagreement 
 of two ideas. This, at leaft, is aflerted by ne- 
 cefTirians^ and it does not depend upon the 
 mind being material or immaterial whether 
 the obfervation be jufl or not. If it be inva- 
 lidated, it muft be on fome other ground than 
 this. I am willing, however, to follow you 
 through all that you alledge in fupport of this 
 argument. 
 
 " Moral neceflity," you fay, p. 45, " arifes 
 " from the influence of motives ; which, as 
 " they are not phyfical beings or fubftances, 
 " cannot pofiibly adt as one phyiical being 
 
 " or
 
 DOCTRINE OF NECESSITY. * 15 
 
 * f or fubftance does upon another." Again, 
 p. 82, "where there is the greateft certainty, 
 <t or neceffity of a moral kind, there is always 
 " a poflibility of a different choice." And, 
 p. 46, " In the ftricl: philofophical fenfe, no- 
 " thing can be neceffary, which is not phy- 
 " lically fo, or which it would not be a con- 
 " tradiclion to the nature of things to fuppofe 
 " not to be, or to be otherwife than it 
 " is. Now this kind of neceffity we clearly 
 " perceive in the cafe of one body adling upon 
 " another, and giving motion to it. But do 
 <( arguments and motives bear the fame phy- 
 *' fical relation to the determinations of the 
 " mind ?" 
 
 I own I am rather furprized at the confi- 
 dence with which you urge this argument, 
 when it is maintained, and infifted on by ne- 
 ceflarians, that arguments and motives do bear 
 as ftricl a relation (call it phyfical or moral, 
 or by whatever name you pleafe) to determina- 
 tions of the mind, as any other caufes in nature 
 to their proper effects -, becaufe, according to 
 
 manifefl
 
 l6 A DEFENCE OF THE 
 
 manifeft appearances, the determinations of 
 the will do, in fact, as certainly follow the 
 apprehenfion of arguments and motives, as 
 any one thing is ever obferved to follow ano- 
 ther in the whole courfe of nature; and it is 
 juft as much a contradiction to fuppofe the 
 contrary in the one cafe as in the other, that 
 is, a contradiction to the known and obferved 
 laws of nature ; fo that they muft have been 
 otherwife than they are now eftablifhed, if 
 any thing elfe mould follow in thofe cafes. 
 No other kind of contradiction would follow 
 in any cafe. 
 
 You fay, however, p. 43, " Phyfical necef- 
 " fity is a neceffity arifing out of the nature 
 " of things, and immediately depending upon 
 " it; fo that while things remain to be what 
 *' they are, it would be a contradiction to fup- 
 " pofe, that the confequences flowing from 
 " this kind of neceffity can be different from 
 " thofe which do actually refult from it. To 
 " fay that any thing is neceffary, in this fenfe, 
 " is the fame as faying that it is a natural 
 
 " impoffibility
 
 DOCTRINE OF NECESSITY. 1J 
 
 " impoflibility for it not to be, or to be dif- 
 " ferent from what it is." And, p. 44, you 
 " fay, " The fall of a ftone is the necefTary 
 " effect of that law of gravity which is im- 
 " preffed upon it." 
 
 Now I do maintain, and all appearances 
 will juftify me in it, that a determination 
 of the mind according to motives is, ufing 
 your own words, that which arifes from the 
 very nature of the mind, and immediately 
 dependent upon it -, fo that the mind remain- 
 ing what it is, and motives what they are, 
 it would be a contradiction to fuppofe that 
 they mould be different from what they are 
 in the fame circumftances. The parallel be- 
 tween material and immaterial natures is 
 here moft ftrict, and the inference the very 
 fame in the one cafe as in the other. ^If the 
 fall of a ftone be the neceffary effect of gra- 
 vity impreffed upon it, or upon body, in the 
 very fame fenfe (becaufe for the very fame 
 reafon) the determination of the will is the 
 neceffary effect of the laws impreffed upon it, 
 C or
 
 l8 A DEFENCE OF THE 
 
 or upon mind. ' This conclufion is as much 
 grounded on facts and appearances as the 
 other. 
 
 Nay, beginning with mind, I might, ac- 
 cording to your mode of feafoning, fay firft, 
 that, according to all appearances, the mind 
 is neceflarily determined by motives, for every 
 thing we fee in human nature confirms it. 
 Mind is, therefore, fubject to fixed laws, but 
 matter is a thing totally different from mind. 
 It cannot, therefore (whatever appearances 
 may be) refemble mind in this, or any other 
 refpeft, and confequently muft be free from 
 all fixed laws whatever. Thus might your 
 own arguments be retorted upon you, and 
 bring you to an evident abfurdity; but, in 
 my opinion, not a greater abfurdity, or more 
 contrary to fact, than that the mind is free 
 from all fixed laws, and endued with a power 
 of felf-determination. 
 
 \I wifh, however, you would explain in 
 what fenfe it would be a contradiction for a 
 
 flone
 
 DOCTRINE OF NECESSITY. 19 
 
 ftone not to fall to the ground. It is only 
 from the obfervation of thefatf that we find 
 it does tend to the ground. A priori, it would 
 have been juft as probable that it might have 
 tended to recede from the ground, and to rife 
 upwards. Where alfo would be the contra- 
 diction, in any proper fenfe of the word, if 
 acids did not unite with alkalies, or if water 
 mould take fire and burn, like fpirit of wine? 
 No perfon, I prefume, is fufficiently acquaint- 
 ed with the nature of things, to pronounce, 
 that there would be any thing that could be 
 called a contradiction in refults the very oppo- 
 fite of what we fee do take place/ 
 
 That which approaches the neareft to a 
 properly neceiTary efFecl:, is the receding of bo- 
 dies after impulfe, which you alfo maintain. 
 But, though you fay you clearly perceive this 
 neceflity, even this is a cafe in which, I will 
 take upon me to fay, you cannot demon/Irate 
 the confequence to be necefTary. For, as I 
 prefume I have fhewn at large, there is not 
 attual contact in all cafes of feeming impulfe, 
 C 2 and,
 
 20 A DEFENCE OF THE 
 
 and, therefore, the receding of one body from 
 another, in thofe circumftances, is owing to a 
 real repulfion, which we can no more refolve 
 into a mechanical effect, than we can thofe of 
 gravity, becaufe they both take place at a dif- 
 tance from the bodies concerned. 
 
 Now, as it is fimply in confequence of the 
 obferved uniformity of the f aft t that I conclude 
 a ftone will fall to the ground, it is equally 
 in confequence of the obferved uniformity of 
 the fact, that I conclude the determination 
 of the mind will follow the motive. An in- 
 ference from obfervation is furely as decifive 
 in one cafe as in the other; and this is clearly 
 independent of all confideration of the mind 
 being material or immaterial.

 "VT'OU feem fometimes willing to allow that

 not necejjary ; fo that the arguments in favour

 " The argument itfelf," you fay, p. 74,

 Now, this is a cafe that I had confidered 
 fo fully in my late Treatife, in my Corre/pon- 
 dence with Dr. Price, and in my Letters to 
 Dr. Horjley and Mr. Eermgton y that I did 
 not think I mould have heard any more of it ; 
 and yet it feems you have read part, at leaft, 
 of what I have advanced on that fubject; for 
 you fay, p. 40, " The beft reafon that I can

 " cedon this fubject, in favour of fuch aphy-

 " of the effects, that is, of the determination 
 " which takes place in any given circumftan-

 " particular effect would ever fo certainly 
 " follow on a ftate of mind, and a fituation 
 of external objects correfponding with it, 
 " this will not prove the effect to be necef- 
 " fary. A moral certainty, and a phyfical 
 " neceffity, or a neceffity arifmg out of the 
 " nature of things, cannot but imply in them 
 " very different ideas \ nor is the latter by 
 " any means the confequence of the former." 
 
 You
 
 DOCTRINE OF NECESSITY. 23 
 
 You have, indeed, been able to collect, 
 which was not difficult, (for I had ^occa- 
 fion to repeat it feveral times) that, in fa- 
 vour of the neceflary determination of the 
 mind according to motives, I have urged 
 the certainty and univerfality of fuch a deter- 
 mination ; but I wonder you mould not like- 
 wife have obferved, that, in farther fupport 
 of this, I added, that certainty or um'ver- 
 fality is the only pojible ground of concluding^ 
 that there is a necejjity in any cafe whatever ; 
 and to this, which you have not fo much as 
 noticed, you ought principally to have replied. 
 
 Pleafe, Sir, to reflect a moment, and tell 
 me diftinctly, why you believe that there is 
 a neceffity that a ftone muft fall to the ground ? 
 Can it be any thing elfe than its having been 
 obferved that it conftantly and univerfally does 
 fo ? If, therefore, the determination follows 
 the motives as certainly as a ftone falls to the 
 ground, there muft be the very fame reafon to 
 conclude, that, whether we fee why it is fo or 
 not (which, indeed, we do not in the cafe of 
 
 C 4 the
 
 24 A DEFENCE OF THE 
 
 the falling of the flone) there is a necejfity for 
 its doing fo. The difference cannot be in the 
 reality, but only in the kindoi neceffity. The 
 neceffity mufl be the fame, or equally ftrict 
 and abfolute in both, let the caufes of the ne- 
 ceffity in the two be ever fo different. 
 
 ^As I have told Dr. Horfley, but which you 
 feem not to have attended to, (fee Correfpon- 
 dence with Dr. Price, p. 223,) " I will allow 
 " as much difference as you can between mo- 
 " ral and phyfical caufes. Inanimate mat- 
 " ter, or the pen that I write with, is riot ca- 
 " pable of being influenced by motives, nor 
 '* is the hand that directs the pen, but the 
 <f mind that directs both.) I think I diftin- 
 " guifh thefe things better by the terms vo- 
 " luntary and involuntary, but thefe are mere 
 " words, and I make no comparifon between 
 " them, or between moral and phyfical caufes, 
 " but in that very refpect in which you your-

 " terms by which we diftinguifh the laws and 
 " caufes that refpect the mind from thofe 
 " which refpect the external world. That 
 " there are any laws, and that there are any 
 " caufes, to which the mind is fubject, is all 
 " that my argument requires. Give me the

 Thefe paflages, I prefume, you have over- 
 looked. You certainly have not noticed 
 them, or given due attention to them. 
 
 You muft give me leave to obferve, on this 
 fubjedl si moral certainty, that you feem fome- 
 times to have deceived yourfelf, by an ambi- 
 guous ufe of that term. Becaufe we are apt 
 to be deceived in our judgments concerning 
 the fentiments and conduct of men, fo that 
 the greateft certainty we can attain to with 
 refpect to them is frequently imperfect, we 
 diftinguifh it from abfolute certainty, by call- 
 ing it moral, and then apply the fame term 
 to other things, calling that a moral certainty, 
 which is only a great probability. Thus, in 
 the docTrine of chances, if there be a thoufand 
 to one in my favour, I fay there is a moral 
 certainty that I mall fucceed. But it does not 
 follow that, becaufe the term moral certainty 
 
 has
 
 POCTRINE OF NECESSITY. 7 
 
 has by this means come to mean the fame 
 thing with a high degree of probability y nothing 
 relating to the mind can have any thing more 
 than a moral certainty, that is, a probability ', 
 attending it. Many propolitions relating to 
 the mind are as abfolutely certain as any re- 
 lating to the body. That the will conftantly 
 and invariably decides according to motives, 
 muft not, therefore, be concluded to have no- 
 thing more than a moral certainty attending 
 it, merely becaufe it is a truth relating to the 
 mind, or to morals. It may be as abfolutely 
 certain as any truth in natural philofophy. 
 It is the evidence of the fafl that mould be 
 confidered, and not the mere nominal diftinc- 
 tions.of things. 
 
 For the farther illuflration of this fubjedt, 
 I hope to fatisfy you, that even all that you 
 defcribe as moft horrid and frightful in the 
 doctrine of necejflty, follows as evidently from 
 your dodtrine of certainty, provided it be a real 
 certainty, though not fuch as you would chufe 
 to call a phyfical one ; and, therefore, that it 
 
 can
 
 28 A DEFENCE OF THE 
 
 can be nothing more than the mere name that 
 you objedlto. 
 
 / We will fuppofe that a child of yours has 
 committed an offence, to which his mind was 
 certainly, though not necejjartiy> determined by 
 motives. He was not made, we will fay, in 
 fuch a manner as that motives had a necef- 
 fary effedt upon his mind, and pbyfically or 
 mechanically determined his actions, but only 
 that his mind would in all cafes determine it- 
 Je/f, according to the fame motives. You hear 
 of the offence, and prepare for inftant correc- 
 tion, not, however, on the idea that punifh- 
 ment is juftifiable whenever it will reform the 
 offender, or prevent the offences of others ; 
 but fimply on your own idea, of its having 
 .been in the power of the moral agent to acl: 
 otherwife than he had done. 
 
 Your fon, aware of your principles, fays, 
 dear father, you ought not to be angry with 
 me, or punim me, when you knew that I 
 could not help doing as I have done. You 
 
 placed
 
 DOCTRINE OF NECESSITY. 29 
 
 placed the apples within my reach, and knew 
 that my fondnefs for them was irrefiftible. No, 
 you reply, that is not a juft ftate of the cafe, 
 you were not under any necejfity to take them, 
 you were only .fo conftituted as that you cer- 
 tainly would take them. But, fays your fon, 
 what am I the better for this freedom from, 
 neceffity ? I wim I had been necejfarily deter- 
 mined, for then you would not punim me $ 
 whereas now that I only certainly determine 
 myfelf, I find that I offend juft as much, and 
 you always correct me for it. 
 
 A man muft be peculiarly conftituted, if, 
 upon this poor diftindtion, he could fatisfy 
 himfelf with punifhing his fon in the one 
 cafe, and not in the other. The offence he 
 clearly forefaw would take place : for by the 
 hypothecs, it was acknowledged to be certain , 
 arifing from his difpofition and motives ; and 
 yet merely becaufe he will not term it necejfa* 
 ry> he thinks him a proper objedl of punifh- 
 ment. Befides, pleafe to confider whether, 
 if the child never did refrain from the offence 
 
 in
 
 30 A DEFENCE OF THE 
 
 in thofe circumftances, there be any reafon to 
 think that he properly could have refrained. 
 We judge of all powers only by their effe&s, 
 and in all philofophy we conclude, that if 
 any thing never has happened, and never will 
 happen, there is a fufficient caufe, though it 
 may be unknown to us, why it never could 
 happen. This is our only ground of conclu- 
 ding concerning what is poffible or impoffi- 
 ble in any cafe. 
 
 SECTION IV. 
 
 Of the Argument for the Doctrine ofNeceJfity, 
 from the Confederation of Divine Prefcience. 
 
 IF there be any propolition flridlly demon- 
 Jlrabky it is, as it appears to me, that a 
 contingent event is no objett of prefcience, or 
 that a thing which, in its own nature, may, 
 
 or
 
 DOCTRINE OF NECESSITY. 3! 
 
 or may not be, cannot be certainly known to 
 be future ; for then it might be certainly 
 known to be what it confefledly may not be, 
 If, therefore, the mind of man be fo conftitu- 
 ted, as that any particular determination of his 
 will may or may not take place, notwithftand- 
 ing his previous circumflances, the Divine 
 Being himfelf cannot tell whether that deter- 
 mination will take place or not. The thing 
 itfelf is not fubject to his controul, nor can 
 be the object of his fore-knowledge. 
 
 To fay, as you quote from fome other per- 
 fon, p. 33, but without any declared appro- 
 bation, that " fore-knowledge, if it does im- 
 " ply certainty, does yet by no means imply 
 " necejjity, and that no other certainty is im- 
 " plied in it than fuch a certainty as would 
 " be equally in the things, though there was 
 " no fore-knowledge of them," is too trifling 
 to deferve the leaft attention. You, there- 
 Core, in fact, give it up, and as, according to 
 your fyftem, the Divine Being cannot have 
 this fore- knowledge, you take a good deal of 
 
 pains
 
 32 A DEFENCE OF THE 
 
 pains to mew that he may do very well with- 
 out it. 
 
 " Prefcience," you fay, p. 31, "is by no 
 " means effential to the government of free 
 
 " beings, and a government of this na- 
 
 " ture, though prefcience mould be deemed 
 " inadmiffible, as a contrariety to contin- 
 " gency in the event, may, notwithftand- 
 " ing, be as complete in its defigns and ope- 
 " rations, as the utmoft poflible extent of 
 " knowledge, that is, the moil perfect know- 
 " ledge united with almighty power, can 
 " make it." This, however, in thefe cir- 
 cumftances, may be very incomplete, and in- 
 adequate for its purpofe. You add, p. 30, 
 " it cannot be impoflible to almighty power, 
 when the charadters of men are known, 
 " becaufe really exifling, to bring about by 
 " means, which, previous to their operation, 
 " we cannot forefee, thofe events which he 
 " judges fit, and proper, for the maintainence 
 " and promotion of the well-being of his 
 " rational creation. And, after all, whatever 
 
 prefent
 
 DOCTRINE OF NECESSITY. 33 
 
 " prefent irregularities may be permitted to 
 " take place in the allotments of Providence 
 " to the fons of men, the grand and ultimate 
 " part of the plan of God's moral govern- 
 " ment, in the exacT: and equal diftribution 
 " of rewards and punifhments in a future 
 " fcene of exiftence, /lands on the fame 
 " firm and immovable grounds, whether 
 " the contingent actions of men be fqrefeen 
 " or not." 
 
 This, and what you farther advance on 
 the fame fubject, I really am not able to read 
 without pain and concern. You fay, p. 32, 
 that " the prophecies of fcriptures do im- 
 (t ply divine preference in certain instances 
 
 " mufl be allowed." Now, unable as you 
 evidently are to defend the very pojjibitity of 
 this prefcience; this conceffion is rather ex- 
 traordinary. To be truly confident, and, at 
 the fame time, a believer in revelation, you 
 ought to aflert, how embarrafTed foever you 
 might be in making out the proof of it, that 
 
 D there
 
 34 A 
 
 there is no real fore- knowledge where a di- 
 rect interference is not to be underftood. 
 
 To leflen this difficulty, you fay, p. 27, 
 that, " by denying that prefcience to God, 
 " which is inconfiftent with the idea of li- 
 " berty or agency in man, we only deny that 
 " to belong to the fupreme mind, which is, 
 " in truth, no perfection at all. For, if it be 
 " really impofiible that even infinite know- 
 " ledge mould extend to actions or events in 
 " their own nature contingent, that is, where 
 "proper liberty or agency is fuppofed, we no 
 " more derogate from the perfection of the di 
 " vine knowledge, by maintaining that God 
 " cannot know fuch actions or events, than we 
 tf diminim his power by aflerting that it can- 
 " not work contradictions, or what is really 
 " no object of power at all. Equally muft 
 " it confift with the omnifcience of the di- 
 vine being, to fay he cannot know that 
 " which is impoffible to be known, as it 
 *' does with his omnipotence to afTert that 
 
 he
 
 DOCTRINE OF NECESSITY. 35 
 
 " he cannot do that which is impoflible to 
 " be done." 
 
 I mould think, however, that it muft be 
 a matter of deep regret to the human race, 
 that the object of our fupreme veneration and 
 worfhip, on whom we conftantly depend for 
 life, breath, and all things, mould want fuch 
 an attribute as that of prefcience, though it 
 mould be impoffible that he could be poffefTed 
 of it. It would certainly be more fatisfac- 
 tory to us to be dependent upon a being 
 who had planned, and provided for the whole 
 courfe of our exiftence, before we came into 
 being, than en one who could not tell what 
 turn things would take with refpect to us the 
 next moment of our lives, and who muft, 
 therefore, either interpofe by a proper mira- 
 cle when we fall into any unforefeen misfor- 
 tune, or leave us to ftruggle with it, and 
 be overwhelmed by it. 
 
 It is certainly no reflection upon me that 
 I cannot fee into the table I write on, and 
 
 difcover
 
 36 A DEFENCE OF THE 
 
 difcover the internal texture of it; but I know 
 that, as a philofopher, it would be a great 
 perfection and advantage to me if I occafion- 
 ally could.' I cannot help thinking that, 
 with lefs ingenuity than you have employed 
 to (hew how the Divine Being might do 
 without prefcience, that is, without omnifci- 
 ence, you might prove that a power much 
 fhort of omnipotence, and a degree of goodnefs 
 much lefs than infinite, might fuffice for him ; 
 and you might fay it would be no reflection 
 upon him at all to be lefs the objeft of love 
 and reverence than we now conceive him to 
 be. It can be no detraction, you might fay, 
 from any being, or degradation, to deny him 
 what he never could have. 
 
 I rejoice that my opinions, whether true or 
 falfe, oblige me to think with more reverence 
 of the Supreme Being. It gives me a higher 
 idea of my own dignity and importance, from 
 a fenfe of my relation to him, and depend- 
 ance upon him. You fay, however, p. 216, 
 that " the only character which the necefla- 
 
 rian
 
 DOCTRINE OF NECESSITY. 37 
 
 rian tenet, if confidered in its due extent, 
 will admit of, as belonging to the uncreated 
 mind, is a mixed one, in which, if I may fo 
 fpeak, matchlefs virtues and matchlefs vices 
 are blended together." And again, p. 188, 
 he cannot but appear to be (horrid thought) 
 " the moft finful of all beings." Horrid 
 thought indeed. But remember, it is not the 
 neceffarian who has himfelf this idea of the 
 object of his worfhip. , This is only what 
 you think for him ; whereas it is yourfelf that 
 deprive the Divine Being of his prefcience ; 
 which makes no fmall difference in*the cafe. 
 It is of little confequence to me what you 
 think of the God that I wormip, though it 
 hurts me to hear him reproached in this 
 manner. It is as little to you what / think 
 of him whom you, or any other perfon, pro- 
 fefles to wormip; but what we ottrfe/ves think 
 of him is a very ferious bufinefs. 
 
 Being aware of the impoffibility of carry- 
 ing on a fcheme of perfect moral government 
 on your principles, without having recourfe 
 D 3 to
 
 38 A DEFENCE OF THE 
 
 to a future ftate, you, however, make yourfelf 
 eafy about any irregularities that cannot be 
 remedied here, on the idea that every thing 
 that unavoidably goes wrong in this life, 
 will be fet to rights in another. But will not 
 the fame irregularities unavoidably arife from 
 the fame caufe, the fame felf-determining 
 power, in a future life as well as in this ? 
 You will hardly fuppofe that men will ever 
 be deprived of a privilege which, in your ef- 
 timation, is of fo much importance to them. 
 The nature of man will not be fundamentally 
 changed, nor the nature of his will} and if 
 this faculty retain the fame character, it muft 
 be as much as ever perfectly uncontrolled ei- 
 ther by the influence of motives, or by the 
 deity himfelf. It will ftill, then, for reafons 
 of its own, or for no reafon at all, pay juft as 
 much or as little regard to every thing foreign 
 fo itfelf, as it pleafes. Even habits, which 
 may be acquired in this life, operate only as 
 motives, or biafes, inclining the mind to this 
 or that choice, and nothing coming under that 
 defcription has any decifive influence. 
 
 Here

 Here is, therefore, from the unalterable 
 nature of things, an everlafting fource of ir- 
 regularity, which muft always be fufferad 
 for the prefent, and which can only be reme- 
 died in fome future ftate. Thus periods of 
 diforder, and periods of rectification, muft fuc- 
 ceed one another to all eternity. What a 
 profpedl does this view of things place be- 
 fore us ! 
 
 You afk me, p. 33, " how far it would be

 " Thus," you fay, p. 34, " our author, in

 " really true, it muft be unfpeakably injurious 
 " both to the virtue and happinefs of the ge- 
 " nerality of mankind to make public." 
 
 I thank you, Sir, for the opportunity you 
 have given me of trying how I mould feel on 
 this ocean* on. For, other wife, we are fo apt 
 to overlook beams in our own eyes, while we 
 
 can

 can difcover motes in the eyes of others, that 
 I might not have attended to it ; and I will 
 tell you frankly how it is with me. Had I 
 thought the reflection juft, I mould have felt 
 it; though feeing it to proceed from an hontft 
 zeal, mould not have thought it contrary to 
 any thing that ought to be termed civility, or 
 candour. But becaufe I confider it as altoge- 
 ther founded on a miftake, I think it injurious 
 to me, and unworthy of you. 
 
 I really fufpecl: that neither you nor Dr. 
 Beattie have fufficiently attended to the proofs 
 of the divine prefcience, either from reafon 
 or revelation. For they appear to me really 
 ftronger, and more ftri&ly conclufive, than the 
 arguments we have for his omnipotence or his 
 infinite goodnefs ; and the Divine Being him- 
 felf propofes this as the very teft and touch- 
 ftone of divinity itfelf, fo that a being not 
 poffefTed of it is not, in a ftridt and proper 
 fenfe, intitled to the appellation of God. 
 '* Thus faith the Lord," Ifa. xli. 22, con- 
 cerning idols, "Let them mew us what fhall

 '* happen. Let them (hew the former things 
 " what they be, or declare us things to come. 
 " Lei them mew the things that are to 
 " come hereafter, that we may know that they 
 " are Gods." 
 
 This, I own, is preaching to one whofe of- 
 fice it is to preach to others; but I muft preach 
 on, and obferve, that if you will only attend 
 to the amazing variety and extent of the fcrip- 
 ture prophecies, comprizing the fate of all the 
 great empires in the world, the very minutice 
 of the Jewifh hiftory, and all that is to befall 
 the chriftian church to the very end of the 
 world, you cannot entertain a doubt, but that 
 every thought in the mind of every man 
 (aftoniming as the idea is) muft have been 
 diftin&ly perceived by the fupreme ruler of 
 all things from the beginning of the world. 
 
 You fay, "the prophecies of fcripture im- 
 " ply prefcience in certain inftances" This 
 is greatly narrowing the matter, and giving 
 an idea of it far below the truth. They not 
 
 only
 
 DOCTRINE OF NECESSITY* 43 
 
 only imply y but directly ajfert it in numberlefs 
 inftances ; and it is implied, I may fay, in an 
 infinity of inftances. Confider only, for I 
 think it very poffible that you may never have 
 attended to it at all (as your principles -will 
 naturally incline you to look another way) 
 confider, I fay, how many millions of human 
 volitions muft have taken place from the be- 
 ginning of the world, that really (directly or 
 indirectly) contributed to the death ofCbrift, in 
 the very peculiar circumftances in which it was 
 actually foretold ; volitions which, according 
 to all appearance (from which alone we are 
 authorized to form any conclufion) were per- 
 fectly natural, and uncontrolled by fuperna- 
 tural influence; and you cannot think it ex- 
 travagant to fay, that all the volitions of the 
 minds of all men muft have been known 
 to him that could foretel that one event, in 
 its proper circumftances. Not only muft he 
 have forefeen the tempers and difpofitions 
 of the rulers and common people of the Jews, 
 the peculiar character of Pilate, Herod, and 
 of every man immediately concerned in the 
 
 tranf-
 
 44 A DEFENCE OF THE 
 
 tranfa&ion, and the peculiar manners and 
 cuftoms of the Romans, but all that had prece- 
 ded, to give the Romans theirpower, and form 
 their manners and cuftoms, as well as thofe 
 of the Jews and other nations. Think but a 
 few minutes on the fubject, and it will fwell 
 far beyond your power of conception, and 
 overwhelm you with conviction. It impreiTes 
 my mind in fuch a manner, that, I own, I 
 cannot help being extremely mocked at the 
 feeming levity with which you treat this moil 
 ferious of all fubjects. 
 
 Such is the evidence of the divine prefci- 
 cnce from the consideration of the fcripture 
 prophecies, that, if they be duly confidered, 
 I do not think it in the power of the human 
 mind to refift it ; and without regard to any 
 confequencesy that metaphyfical fyftem which 
 implies it, and is implied by it, muft be true: 
 And when the whole fcheme is feen in its true 
 colour and form, nothing can appear more 
 admirable and glorious, more honourable to 
 God, or more happy for man. But I will not 
 
 enlarge
 
 DOCTRINE OF NECESSITY. 45 
 
 enlarge on the fubjeft, though I can hardly 
 forbear doing it. 
 
 Compared with this, how exceedingly low 
 and poor muft be their idea of the moral go- 
 vernment of God, who hold him to have no 
 fore- knowledge of the actions of men; and 
 with what little fatisfa&ion can they contem- 
 plate it ? Only confider on that hypothefis, 
 the millions, and millions of millions of vo- 
 litions that take place every moment, on the 
 face of this earth only, which the Divine 
 Being, having no proper forefight of, can- 
 not poffibly control. For the mind of man 
 is held to be as abfolute, and uncontrolled, 
 within its proper fphere, as the Divine Being 
 is in his. The unknown effects of all thefe 
 volitions he muft always be anxioufly watch- 
 ing, in order to remedy the inconveniencies 
 that may ariie from them as foon as poffible ; 
 and he muft have a diftinct expedient provided 
 for every contingency. What regularity or 
 harmony can there be on fuch a Icheme as 
 this ? What'ftrange uncertainty, confufion, 
 
 and
 
 46 A DEFENCE OF THE 
 
 and perplexity, muft reign every where ! I 
 am unable to proceed any farther with the 
 fhocking picture. I thank God that fuch is 
 not my idea of the government under which 
 I really live. 
 
 To give our common readers an opportu- 
 nity of judging of the paragraph which you 
 think fo obnoxious, and which you have ta- 
 ken care to bring into their view more than 
 once, I mall myfelf recite the whole, with 
 fome things that precede and follow it.

 vourite theme, I am perfectly fatisfied with 
 what I have already advanced, and think it 
 altogether unaffected by your reply. Befides, 
 it behoves you, in the firft place, to prove the 
 doctrine to be falfe. For if it be true, the 
 confequences will follow, and you as well as 
 myfelf, muft make the beft we can of them. 
 And I befeech you, for your own fake, that 
 you would not reprefent them as fo very 
 frightful, left, after all, they jhould prove 
 true. 
 
 In the mean time, have fome little tender- 
 nefs for me, and confider with what fentiments, 
 one who firmly believes the doctrine of ne- 
 ceffity to be true, and at the fame time to 
 abound with the moft glorious confequences, 
 who imagines he feels it favourable to true 
 elevation of mind, leading, in an eminent 
 manner, to piety, benevolence, and felf-go- 
 vernmcnt, muft perufe the account you have 
 been pleafed to draw of his principles. *The 
 following are but a few of the features :

 " I cannot but think," you fay, p. 242, 
 f that the doctrine of neceffity looks very 
 * f much like a refinement on the old Mani-

 '* pies of good and evil, which, in this fyftem, 
 *' are blended in one." " I cannot butthink/' 
 you fay, p. 183, (< fuch fentiments as danger- 
 f ' ous in their tendency, as they are falfe and 
 " abfurd in themfelves. They fecm very ma- 
 " terially, though undefignedly, to affecl: the 
 " moral character of the deity, and to be big 
 * f with confequences the mofl fatal to the

 " not but look upon the promulgation of the 
 " fcheme of neceffity," p. 175, "as highly 
 " exceptionable, becaufe it is likely to do 
 " unfpeakable mifchief. In the moft ex- 
 " ceptionable and dangerous principles of 
 " Calvinifm, p. 238, the doctrine of ne- 
 " ceffity, when examined to the bottom, 
 V is really the very fame." And in your 
 preface, p. 4, you fay, " nor can I help 
 " expreiling very flrong apprehenfions of 
 f the dangerous tendency of the neceiTarian

 " tenet as a practical principle ; for that the 
 tf generality of mankind would think them- 
 " felves fully warranted in concluding that 
 " they could not, on any account, defervc 
 " punimment, and had therefore nothing 
 " to fear." 
 
 Before you had concluded, as you have 
 done, that the publication of the doctrine of 
 neceffity muft do fuch unfpeakable mifchief 
 to the generality of mankind* you would have 
 done well, I think, to have confidered the 
 flate of thefafl. Caft your eye over thofe 
 of your acquaintance, and whom you know 
 to be necelTarians, efpecially thofe who have 
 been fo in early life, and who are the moft 
 attached to the doctrine. They are nume- 
 rous enough to enable you to form fomc 
 judgment of the practical tendency of their 
 principles. Are their minds more depraved, 
 their objects of purfuit lefs noble, or their 
 exertions lefs ftrenuous, than you have reafon 
 to think they would have been if they had 
 pot been necelTarians ?

 Had I not been engaged, in this contro- 
 
 verfy, you would probably have thought my 
 
 own evidence as unexceptionable as that of 
 
 any other perfon. But on this I lay no 
 
 Jftrefs, though the compliments you pay me 
 
 would give me fomc advantage in this cafe. 
 
 If you fay that principles in general have but 
 
 an inconfiderable- influence on practice, v/hy 
 
 fhould you fufFer your fears to get the better 
 
 of your reafon in this particular cafe, and 
 
 why mould you urge what is, in fadl, no 
 
 proper argument at all, with more force, than 
 
 every other confideration, refpecting the real 
 
 merits of the queftion ? 
 
 However, light as I ihould be difpofed 
 to make of your accufation, I mall now treat 
 it with the gravity that yourfelf will think 
 it intitled to ; and I think I may undertake 
 to fatisfy you, from your own mode of ar- 
 guing, that there is no evil whatever to be 
 apprehended from the doclrine of neceffity, 
 but, on the contrary, the greateft good, and 
 that you evidently argue on principles in- 
 confiftent with each other when you throw 
 
 fo much odium on the fcheme. 
 
 In
 
 DOCTRINE OF NECESSITY. 55 
 
 In the firft place, you fay, p. 149, that 
 " on the fcheme of neceflity all is refolved 
 " into a divine conftitution, which is unal- 
 " terably fixed. If any, therefore, are to 
 " fucceed better, or be happier, in any part 
 " of their exiftence than others, their fupe- 
 " rior profperity and happinefs will be infal- 
 " libly fecured to them ; and though there 
 " is a certain difpofition of mind, and courfe 
 " of action, which are infeparably connected 
 " with their fuccefs and happinefs, as means 
 " to bring about thofe events, yet the means 
 " as well as the end are alike neceffary ; and 
 " having no power to make either the one 
 " or the other at all different from what 
 " they are, or are to be, their lot, through 
 " the whole of their being, is by them abfo- 
 " lutely unalterable. What, again, I fay, 
 can have a ftronger tendency to relax the 
 " mind, and fink it into a ftate of indolence 
 " and inactivity?" 
 
 Here then you reduce the neceflarian to a 
 
 ftate of abfolute inattmity, that is, indifpofed 
 
 4 to
 
 56 A DEFENCE OF THE 
 
 to any purfuits, virtuous or vicious. For 
 your argument, if it goes to any thing, goes 
 to both alike. 
 
 But, on the other hand, you conftantly 
 fuppofe, fo that I have no occafion to quote 
 particular paflages, that the neceflarian wilJ, 
 of courfe, give himfelf up to the gratifica- 
 tion of all his paflions, and purfue without 
 reftraint whatever he apprehends to be his 
 intereft or happinefs. 
 
 Here then, notwithftanding the natural 
 mdolence of the neceflarian, you are able, 
 when your argument requires it, to find a 
 conliderable fource of a&itoity in him 3 be- 
 caufe you have difcovered, that, like other 
 men, he has pajfions, and a regard to his inte- 
 reft and bappinefs. 
 
 But, furely, it is not difficult to conceive, 
 that this activity, from whatever fource it 
 arifes, may take a good as well as a bad turn, 
 and lead to virtue or vice, according as it is 
 
 directed.
 
 bod TRINE oF NECESSITY, $j 
 
 directed. If the gratification of our lower 
 appetites leads to evil, the gratification of 
 the higher ones, as benevolence, &c. (of 
 which, I hope, you will admit that a necef- 
 farian, being a man in other refpects, may be 
 pofTeffed) muft lead to good; and that, if 
 falfe notions of intereft and happinefs in- 
 ftigate a man to vice, juft notions of his in- 
 tereft and happinefs muft lead to virtue. In 
 fact, therefore, upon your own principles, 
 nothing is requifite to convert even a necef- 
 farian from vice to virtue, but the better in- 
 forming his underftanding and judgment, 
 which you exprefsly allow to be mechanical 
 things, being always determined by a view 
 of the objects prefented to them, and to have 
 nothing of felf-determination belonging to 
 them. 
 
 This, if there be any force in your own 
 reafoning, muft be a fufficient anfwer to 
 every thing that you fo pathetically and re- 
 peatedly urge concerning the mifchiefs to be 
 dreaded from the doctrine of necefiity. It 
 
 would
 
 $8 A DEFENCE OF THE 
 
 would be very difagreeable to me to go over 
 all that you fay on this fubjec"t, and, there- 
 fore, I am glad to find that I have no oc- 
 cafion to do it. 
 
 I am forry to find that, in purfuing your 
 fuppofed advantage fo inconfiderately as you 
 do, you, in fact, plead the caufe of vice, and 
 reprefent it as triumphing over every confi- 
 deration drawn from the prefent or a fu- 
 ture flate. " How is a vicious man," you 
 fay, p. 185, " who finds that the prefent 
 " natural good of pleafure or profit refults 
 *' from the gratification of his appetites, 
 " and from defrauding or over-reaching his 
 " neighbour, to be perfuaded to think that 
 " vice is productive of evil to him here ? On 
 " the fuppofition that there is no moral dif- 
 " ference in things, all moral arguments 
 " againft the courfe of conduct to which his 
 " appetites or inclinations prompt him, im- 
 " mediately vanim. As long, therefore, as 
 " he can make his prefent conduct confident 
 *' with what is his natural good, or which 
 
 "he
 
 DOCTRINE OF NECESSITY. 59 
 
 *' he looks upon to be fo, that is, with fenfi- 
 " tive pleafure, or his worldly advantage, all 
 " is right and well, fo far as regards the pre- 
 " fent fcene of things." 
 
 Now I am really furprized that you, who 
 have been fo long a preacher, could not, on 
 this occafion, recollect any thing in ahfwer 
 to fuch a libertine as this, without having 
 recourfe to arguments drawn from a future 
 flate, and even independent of moral confi- 
 derations, of which it is but too apparent 
 that mere fenfualifts and worldly-minded per- 
 fons make little account. Do no evils arifc 
 to the bodily conftitution, to the mental fa- 
 culties, or to fociety, from habitual ex- 
 cefs in eating or drinking, or from the irre- 
 gular indulgence of other natural appetites ? 
 And fhort of excefs we are within the bounds 
 of virtue ; for in fact, nothing is ever pro- 
 perly termed excefs, but what does terminate 
 (and it is fo called becaufe it terminates) in 
 pain and milery. Is it not poffible that a, 
 man may both morten his life, and make his 
 
 (hort
 
 60 A DEFENCE OF THE 
 
 fhort life miferable, by his vices ? Only re- 
 perufe your own excellent fermon, intitled, 
 The infanity of the Senfualtft, written long be- 
 fore this controverfy, and you will find many 
 valuable obfervations to this purpofe. 
 
 Suppofing confclence entirely out of the 
 queftion, are injustice and oppreffion always 
 fuccefsful, and are there not many proverbs 
 founded on general experience, teaching even 
 the vulgar, in a variety of expreffion, that, 
 fome how or other, ill-gotten wealth does 
 not contribute to happinefs ? Or, excluiive 
 of the natural courfe of things, are there no 
 fuch things as laws and rnagiftrates in human 
 fociety ? Are there no gallows, gibbets, or 
 wheels, to which flagrant wickednefs may 
 bring a man ? Now may not a necelTarian 
 fee the neceffary connection of thefe natural 
 evils with a courfe of vicious indulgence, as 
 well as. any other perfon - y and, fully appre- 
 hending this, can he purfue the one without 
 chufing his own deftruction, of which I fancy 
 you will allow that he is juft as incapable as 
 any perfon whatever.
 
 6i 
 
 Befides, it is very unfair to fay that becaufe 
 a neceffarian confiders thofe things which are 
 generally termed moral, as coming ultimately 
 under the fame defcription with things na- 
 tural, that, therefore, he believes there are no 
 fuch things at all. You well know that he 
 does not confider thefe things as at all the lefs 
 real, though, as a philofopher, he chufes to 
 give them another name. A fenfe of right and 
 wrong, the flings of confcience, See. (which, 
 however, will not, in general, be fo much 
 felt by thofe who believe no future flate) are 
 things that actually exift, by whatever names 
 they be fignified, and will be felt in a greater 
 or lefs degree by the moft hardened tranf- 
 grefTor. 
 
 (Dr. Hartley and myfelf have endeavoured 
 to mew that the peculiar feeling of remorfe, 
 arifing from afcribing our actions to our- 
 felves, can never vanim, or ceafe to influ- 
 ence us, till we arrive at fuch a comprehen- 
 lion of mind, as will enable us habitually to 
 afcribe every thing to God, and that when 
 
 we
 
 62 -A DEFENCE OF THE 
 
 we are arrived at this ftate, we mall live in 
 communion with God, and mall ftand in no 
 need of fuch a motive to virtue. Before this 
 period, let a man be fpeculatively a necefTa- 
 rian, or whatever he will, and let him pre- 
 tend what he pleafes, it will be naturally im- 
 pojjible for him not to feel all the pungency 
 of remorfe, whenever even yourfelf would 
 fay that he ought to feel it. ) You muft in- 
 validate our reafoning on this fubjecl:, from 
 the confideration of the nature of the human 
 mind, before you can make it appear that a 
 neceflarian, as fuch <, will be a bad man. But 
 as you lay fo very much ftrefs on this fub- 
 jecl: of remorfe of confcience, I will difcufs 
 the matter a little farther with you. 
 
 You fay that remorfe of confcience implies 
 that a man thinks he could have acted other- 
 wife than he did. I have no objection to 
 admit this, at the fame time, that I fay he 
 deceives himfelf in that fuppofition. I be- 
 lieve, however, there are few perfons, even 
 thofe who blame themfelves with the great- 
 eft
 
 DOCTRINE OF NECESSITY. 63 
 
 eft pungency, but, if they will reflect, will 
 acknowledge, that in fo fuppofing, they leave 
 out the confideration of the lituation they 
 were in at the time of the tranfaction, and 
 that with the fame difpofition of mind that 
 they had then, and the fame motives, they 
 mould certainly have acted the fame part 
 over again ; but that having, fince that time, 
 acquired a different difpofition, and different 
 views of things, they unawares carry them 
 back, and coniider how they would have 
 acted with their prefent acquired difpofiti- 
 ons. However, their difpofition being really 
 altered by what has occurred to them fince, 
 they would not now act the fame part over 
 again, and therefore, all the proper ends of 
 remorfe are fufficiently anfwered. 
 
 If you fay that the peculiar feeling of re- 
 morfe is founded on a miftake, I anfwer, fo 
 are the peculiar feelings of anger in moft 
 cafes, and likewife the peculiar feelings of 
 all our paffions, and that a philofopher, who 
 mould have flrength of mind to confider his 
 
 fituation,
 
 64 A DEFENCE OF THE 
 
 fituatJon, would do the fame things coolly 
 and effectually without thztftimulus, that the 
 vu'gir do with it. He would puniih an of- 
 fender without anger, and he would reform 
 his own conduct without remorfe. But nei- 
 ther you nor myfelf, neceffarian as I am, can 
 pretend to this degree of perfection. It is 
 acquired by experience ; and the firmeft be- 
 lief of the doctrine of neceflity can only ac- 
 celerate our progrefs towards it to a certain 
 degree. All this I have endeavoured to ex- 
 plain in my Additional Illujlrations, but you 
 have not noticed it. 
 
 What you fay of the little influence of the 
 motives to virtue which the neceiTarian can 
 draw from the confideration of a future life, 
 by no means concerns the neceffarian as fuch. 
 " In relation to futurity," you fay, p. 185, 
 " it is naturally to be fuppofed, that a man 
 " of this difpofition" (;. e. a vicious neceffa- 
 rian) " will not concern himfelf about it, or 
 "if he does, his neceiTarian principle, by 
 <( holding up to his view his future moral 
 
 cc good
 
 DOCTRINE OP NECESSITY. 65 
 
 *' good or happinefs, as fecured to him by 
 " his omnipotent Creator, will lead him ha- 
 " ftily to pafs over all intermediate fufferings 
 " with which he is threatened, how long or 
 " fevere foever, confidering them only as na- 
 " tural evils, which he can no more avoid 
 " than the courfe of adlion which is connected 
 " with them." 
 
 You know very well that they are not ne- 
 ceflarians only who believe, that all the fuf- 
 ferings of a future life are corrective, and 
 will terminate in the reformation of thofe 
 who are expofed to them. And a man muft 
 not be a neceflarian, but the reverfe of one, 
 and the reverfe of every thing that man is, 
 before he can be made to flight the confide- 
 ration either of prefent or future evils, efpeci- 
 ally long and fevere ones, provided he really 
 believes them, and gives proper attention to 
 them. But with this belief and attention 
 they cannot but influence any man who re- 
 gards his own happinefs, and who believes 
 the infeparable connection between virtue 
 
 F and
 
 66 A DEFENCE OF THE 
 
 and happinefs (which no man believes more 
 firmly than the necefTarian) to have recourfe 
 to a life of virtue, as the only road to happi- 
 nefs, here or hereafter. And having, from 
 whatever motive, begun to tread this path, 
 he will perfift in it from a variety of other 
 and better principles. 
 
 That you mould prefer the Calviniftic 
 doctrine of eternal pumjhments, horrible as 
 you fay it is, to that of univerfal rejloration 
 to virtue and happinefs, could furely be dic- 
 tated by nothing but your abhorrence of the 
 doctrine of neceffity in general, to which it 
 is ufually, but not neceffarily, an appendage. 
 " I cannot but be of opinion," you fay, 
 p. 239, " that the perfualion of the final 
 4 ' reftoration of all the wicked to virtue and 
 " happinefs, which it" (the doctrine of ne- 
 ceflity) " fupports, will, in its natural ope- 
 " ration, have a very pernicious influence on 
 " the unfettled minds of the generality of 
 " mankind : while the doctrine of eternal re- 
 " medilefs torments for the non-elect, taught 
 
 " by
 
 DOCTRINE OF NECESSITY* 6? 
 
 by Calvinifm, horrible as it is in itfelf, 
 may, in the way of reftraint, have a con- 
 fiderable effed:, and in fome inftances may 
 probably produce an external reformation 
 of life." 
 
 You may juft as well fay, that a civil ma- 
 giflrate who punimes without reafon, mercy, 
 or bounds, will be more refpe&ed than an 
 equitable j udge, who exacts an adequate pu- 
 nifhment for every offence. Befides, the doc- 
 trine of eternal punifhments for the offences 
 of a mort life is fo very abfurd, that it muft 
 ever be attended with a fecret incredulity. 
 At leaft, a man, though wicked, yet think- 
 ing he does not deferve the everlafting pains 
 of hell, will not believe that he mail be 
 fent thither, and therefore will indulge a no- 
 tion that he mall go to heaven, and efcape 
 punimment altogether. But I need not ar- 
 gue this point, as it does not belong to me 
 as a neceflarian to do it. I have already 
 argued in my Inftitutes of natural and re- 
 vealed Religion.

 nr^O what I have already advanced in reply

 of the doctrine of neceffity, and the compari- 
 fon of it with the Calviniftic doctrine of pre- 
 defHnation, I mall add, in a fcparate fection, 
 fome conliderations on men's actions as de-

 which you lay fo much flrefs, and which runs

 you deceive yourfelf by the ufe of words, or 
 you could not draw the confequences that 
 you do from what you fuppofe to be my

 Strictly

 J 
 
 Strictly and philofophically fpeaking, my 
 fuccefs in any thing I wifh to accomplish* 
 depends upon myfelf, if my own exertions 
 and actions are neceffary links in that chain 
 of events by which alone it can be brought 
 about. And, certainly, if I do know this, 
 and the object or end be defirable to me, this 
 defire (if it be of fufficient ftrength) cannot 
 but produce the exertion that is neceflary to 
 gain my end. ^This reafoning appears to me 
 extremely eafy, and perfectly conclufive, and 
 yet, though I have repeated it feveral times, 
 and have placed it in a variety of lights, you 
 do not feem to have confidered it. I mall* 
 therefore, give another inftance, and add fome 
 farther illuftrations. 
 
 Can I have a fufficiently ftrong wifh to 
 anfwer your book, and not of courfe read it, 
 mark proper extracts from it, arrange them, 
 write my remarks upon them, then tranfcribe 
 them for the prefs, and put them into the 
 hands of a bookfeller or printer, &c. when I 
 know, that if all this be not done, the book 
 F 3 will 

 
 70 A DEFENCE OF THE 
 
 will never be anfwered ? Surely my firm be- 
 lief that all thefe things are neceffarily con- 
 nected, muft convince me of the neceffity of 
 fetting about the work, if I wifh to do it at 
 all j and my <wijh to have it done is here to 
 be fuppofed, as having arifen from a variety 
 of previous circumftances. 
 
 If, therefore, I mall certainly find myfelf 
 difpofed to a<5t juft as I n6w do, believing my 
 actions to be necefTary, your objection to my 
 doctrine on this account cannot have a furfi- 
 cient foundation. You fay, that if the thing 
 fnuft be, it muft be\ if your book is to be 
 anfwered by me, it will be anfwered by me; 
 and that I may, therefore, make myfelf eafy 
 about it, and do nothing. I anfwer, that fo 
 I mould, either if I had no defire to have it 
 done, which happens not to be the cafe, or 
 if I thought that no exertions of mine were 
 neceffary to gain my end, which is not the 
 cafe neither. On this confideration depends 
 the capital diftinction that I make between 
 
 the
 
 DOCTRINE OF NECESSITY. Jl 
 
 the doctrines of philofophical neceffity and 
 Calviniftic predeftination. 
 
 The Calvinifts make the work of conver- 
 fion to be wholly of God's free and fovereign 
 grace, independent of every thing in the perfon 
 thus regenerated or renovated, and to which 
 he cannot in the leaft contribute. In this 
 work, they fay, God is the fole agent, and men 
 altogether pafiive ; that both to will and to do 
 is of God's pleafure; and fo much fo, that 
 without his immediate agency, to which no- 
 thing on the part of man can contribute, let 
 a man exert himfelf ever fo much, in the ufe 
 of all poffible means, yet all his volitions and 
 all his actions would be only finful, and de- 
 ferving of the wrath and curfe of God to all 
 eternity. 
 
 In this cafe I do not fee what a man can 
 have to do, becaufe his doing, or his not do- 
 ing, is equally unconnected with the end he 
 has in view. But this is the very reverfe of 
 the doctrine of philofpphical neceffity, which 
 F 4 fuppofes
 
 72 A DEFENCE OF THE 
 
 fuppofes a neceflary connection between our 
 endeavours and our fuccefs -, fo that if only 
 the defire of fuccefs > the firft link in this chain, 
 be fufficiently ftrong, all the reft will follow 
 of courfe, and the end will be certainly ac- 
 complifhed. 
 
 According to the Calvinifts, there may be 
 the moft earneft defire, without a man's being 
 at all the nearer to his end, becaufe the defire 
 and the end have no neceflary connection, by 
 means of intermediate links, as we may fay, 
 in the chain that joins them. 
 
 It is on this ground that Dr. Hartley juftly 
 fuppofes that the doctrine of neceflity has a 
 tendency to make men exert themfelves, 
 which he makes the fifth advantage attending 
 the fcheme. " It has a tendency," he fays, 
 p. 344, of my edition, " to make us labour 
 " more earnestly with ourfelves and others, 
 " particularly children, from the greater cer- 
 " tainty attending all endeavours that operate 
 " in a mechanical way.-'

 Another of your arguments relating to this 
 fubjeft, I really cannot treat with fo much fe- 
 rioufnefs as you will probably expeft. I fhall 
 not, however, dwell long upon it, and with 
 this I fhall clofe the fe&ion. 
 
 I had obferved, that a volition may be 
 termed mine, if it takes place in my mind. 
 Animadverting on this, you fay, p. So," Can 
 " that be truly faid to be my volition , my ad, 
 " which is produced by fomething over 
 " which I had no power. On that ground 
 " every thing that takes place in my body, 
 " as well as in my mind*, may with equal 
 " propriety be called my aft or volition ; 
 " and fo the circulation of the blood, and 
 " the pulfation of the heart, may with equal 
 <( reafon be called my volitions." 
 
 Now, Sir, is not judgment always called an 
 aft of the mind, as well as volition ? But has 
 any man power over this ? Is not this ne- 
 ceffarily determined by the view of argu-* 
 ments, &c. ? You will not deny it. Does it 
 
 not,
 
 74 A DEFENCE OF THE 
 
 not, therefore, follow, on your own principles, 
 that whatever paffes in your body, as well as in 
 your mind, may with equal propriety be 
 called an ad: of your judgment , and fo 
 the circulation of your blood, and the pul- 
 fation of your heart, may with equal reafon 
 be called your judgment. But the very fame 
 things were before proved to be volitions. 
 "Ergo, judgments and volitions are the fame 
 things. By the fame mode of reafoning, it 
 would be eafy to prove your head to be your 
 feet, and your feet your head, and both of 
 them to be the fame with your underftand-

 dire&ion, hoping that different views of the 
 fame objedts may be both pleafing and ufeful. 
 
 In general, I think, we mail do well to 
 confider things as much as poflible without 
 the ufe of words, at leaft fuch words as are, on 
 either fide, charged with being the caufes of 
 miftake. I mall treat of the principal of 
 them feparately. 
 
 ift. Of the Term AGENT. 
 
 IN the farther profecution of this debate, 
 do not begin, as you have done now, with 
 affuming that man, in confequence of having 
 a power of choice, is an agent, and that be- 
 ing an agent, he cannot be a mere paffive 
 being, adted upon by motives, &c. but mufl 
 be pofferfed of a power of proper felf-deter- 
 mination. In facl, this is no better than ta- 
 king for granted the very thing in difpute, 
 and therefore you might as well, with Dr. 
 Beattie, difclaim all reafoning on the fubjeft, 
 and affert your liberty on the footing of com- 
 mon fenfe, or inftintf only. 
 
 The
 
 DOCTRINE OF NECESSITY. JJ 
 
 The only unexceptionable method is, to at- 
 tend to the real phenomena of human nature, 
 and to confider the known actions of men in 
 known foliations, in order to determine whe- 
 ther our volitions, which precede all our acti- 
 ons, and direct them, be not always definite in 
 definite circ umftances. If you admit this, and 
 I think it almoft impoflible not to admit it, 
 you admit all that I contend for ; becaufe it 
 will then follow, that from a man's birth to 
 his death, there is an unalterable chain of 
 Jituations and iiolitionsy invariably depending 
 on one another. Your faying that, if this be 
 the cafe, man is no agent, will avail nothing ; 
 for if that word imply more than the adlual 
 phenomena will authorize, the agency of 
 man, in that fenfe of the word, flattering as 
 it may found, muft be given up. 
 
 : .4 
 
 Dr. Price does, in fadr, allow that men's 
 volitions are definite in definite circumftan- 
 ces, for he fays it is the greateft abfurdity to 
 fuppofe that men ever aft either without or 
 againft motives, but that the /elf-determin- 
 ing
 
 78 A DEFENCE OF THE 
 
 ing power is wanted only when the motives 
 are equal ; which, confidering how very fel- 
 dom this can be fuppofed to be the cafe, 
 reduces this boafted liberty of man, in my 
 opinion, to a very fmall matter, hardly worth 
 contending for, 
 
 In this you differ from him. For you 
 carefully avoid making that conceffion, and 
 always, at leait generally, fuppofe the mind 
 capable of acting contrary to any motive 
 whatever. But then you will do well to con- 
 fider whether, confiftently with the pheno- 
 mena, Dr. Price could avoid making that 
 conceflion, alarming as you may think it; 
 and whether it be probable that, in fadt, men 
 ever do aft either without, or contrary to 
 motives. And if he never does, you will not 
 eafily prove that he can. 
 
 If man be an agent, in your fenfe of the 
 word, that is, if his will be properly felf- 
 determined, you muft mew that nothing fo- 
 reign to the will itfelf, nothing that can come 
 
 under
 
 DOCTRINE OF NECESSITY. 79 
 
 under the defcription of motive, or the cir- 
 cumilances in which the mind is, regularly 
 precedes the determination. For if any fuch 
 foreign circumftances, any thing that is not 
 mere will, does conftantly precede every de- 
 termination, we are certainly authorized, by 
 the eftablifhed rules of philofophizing, to 
 confider thefe circumftances as the proper 
 caufes of the determination, and may, there- 
 fore, fay that the will is influenced or acted 
 upon by them, and fo, going backwards in 
 the fame train, we mall conclude that there 
 can be no more than one proper agent in 
 the univerfe. 
 
 2. Of ' Refponfibitity \ 
 
 LET us likewife confider the nature and 
 ufe of moral government, as much as poflible, 
 without the ufe of fuch words as refponfibility, 
 pralfe, blame, &c. and only confider how a 
 wife governor would treat beings whofe wills 
 mould be invariably influenced by motives; 
 and if the proper ends of government would, 
 
 in
 
 A DEFENCE OF THE 
 
 in fad:, be anfwered by annexing happinefs 
 to fuch actions as we call virtuous, and mi- 
 fery to fuch as we call vicious, (fo that every 
 thing we now fee or expect would be done) 
 it will follow, that, for any thing that appears 
 to the contrary, we may be fo conflituted. 
 If the word refponjibility, as you arbitrarily 
 define it, will not apply to fuch a fyftem, it 
 ought to be difcarded from the language of 
 philofophers. 
 
 Take the fame courfe with the words me- 
 rit and demerit, virtue and vice, &c. and on 
 this fubject, attend particularly to what Dr. 
 Hartley, in a very fhort compafs, moft ex- 
 cellently obferves. " It may be faid," fays 
 he, p. 343, " that the denial of free will 
 " deftroys the diftindion between virtue and 
 " vice. I anfwer, that this is according as 
 <f thefe words are defined. If free will be 
 " included in the definition of virtue, then 
 " there can be no virtue without free will. 
 " But if virtue be defined obedience to the 'will 
 " of God, a courfe of aSlion proceeding from the 
 
 " love
 
 DOCTRINE OF NECESSITY. 8l 
 
 " love of God, or from benevolence, &c. free 
 " will is not at all neceflary; fince thefe af- 
 " fedtions and actions may be brought about 
 " mechanically. 
 
 " A folution analogous to this may be 
 " given to the objection from the notions of 
 " merit and demerit. Let the words be de- 
 " fined, and they will either include free 
 " will, or, not including it, will not require 
 " it; fo that the propofition, merit implies free 
 " will, will either be identical or falfe." 
 
 In all that you have faid on the fubjedt of 
 refponfibility, you take your own principles 
 for granted, and then it can be no wonder 
 that all your conclufions follow. You make 
 it effential to refponfibility that man has a 
 power, independent of his difpofition of mind 
 at the particular time, and of all motives, of 
 acting otherwife than he did, and you take 
 not the leafl notice of what I have advanced 
 on that fubject in the Correfpondence vsith Dr. 
 Price, p. 150, &c. where I mow that, not- 
 G withftanding
 
 82 A DEFENCE OF THE 
 
 withftanding it be not in the power of moral 
 agents to ad: othenvife than they do, yet that 
 a moral governor, who confults the good of 
 his fubjects (whofe minds and whofe conduct 
 he knows to be influenced by motives) muft 
 treat them in the very fame manner that you 
 yourfelf acknowledge he ought to do. He will 
 apply fufFering with propriety, and, with good 
 effect in any cafe in which the apprehenfion 
 of it will fo imprefs the minds of his fubjects, 
 offenders and others, as to influence their wills 
 to right conduct. So that, as I have obfer- 
 ved, p. 151, " though the vulgar and philo- 
 <c fophers may ufe different language, they 
 " will always fee reafon to act in the very 
 " fame manner. The governor will rule vo- 
 " luntary agents by means of rewards and 
 " punifhments ; and the governed, being vo- 
 " luntary agents, will be influenced by the 
 " apprehenfion of them. It is confequently 
 " a matter of indifference in what language 
 " we defcribe actions and characters." This 
 you mould have particularly confidered and 
 have replied to. You muft not tell me what 
 
 the
 
 DOCTRINE OF NECESSITY. 83 
 
 the word refponjibility requires ; but you muft 
 {how that, fuppofing men to be what I fup- 
 pofe them, the fupreme ruler ought to have 
 treated them otherwife than he actually has 
 done. If not, every fad: exactly correfponds 
 with my hypothecs, and then on what can 
 your objection be founded, except on fome- 
 thing that is merely verbal. 
 
 3 . Of the Prejudice arljing from the terms 
 MACHINE and NECESSITY. 
 
 YOU miflead and deceive yourfelf, I am 
 perfuaded, not a little, by the frequent ufe 
 of the opprobrious term machine, faying, in 
 the firft place that, becaufe a man wills ne- 
 cej/arily, that is, definitely in definite circum- 
 ftances, he wills mechanically -, and then hav- 
 ing made a man into a machine, you, unknown 
 to yourfelf, conned: with it every thing op- 
 probrious and degrading belonging to a com- 
 mon clock, or a fulling-mill. 
 
 G 2 But
 
 84 A DEFENCE OF THE 
 
 But you might eafily correct this by only 
 confidering what you yourfelf allow to be 
 necefTary relating to the mind of man, viz. 
 perception and judgment. Is there not fome- 
 thing inconceivably more excellent in thefe 
 powers than in thofe of common machines, 
 or mills, and even fomething that bears no 
 refemblance to any thing belonging to them, 
 though they all agree in this one circum- 
 ftance, that their refpe&ive affections are ne- 
 ceffary ? Now fuffer your mind to be fuffi- 
 ciently imprefled with the wonderful nature 
 and excellence of the powers of perception 
 and judgment, and you cannot think the will 
 at all degraded by being put on a level with 
 them, even in the fame refpedl in which 
 they all agree with any common machine, 
 or a mill, viz. that all its affections are de- 
 finite in definite circumstances, though this 
 property be beft expreffed by the term ne- 
 ce/ary. 
 
 If you fuffer your mind to be affected by 
 fuch prejudices as thefe, you may decline 
 
 applying
 
 DOCTRINE OF NECESSITY. 85 
 
 applying the term fubjtance to the mind, be- 
 caufe it is likewife applied to wood and flone, 
 and oblige yourfelf to invent fome other term 
 by which to diftinguifh it from them. 
 
 With refpect to the Divine Being, you 
 will not fcruple to fay, that his adtions are 
 always definite in definite circumftances, and 
 if you decline applying the term neceffary to 
 them, it is only becaufe you conceive that 
 it implies fomething more than definite in de- 
 finite circumftanceSj whereas the two phrafes 
 are perfectly fynonymous, and it is nothing 
 but the word that you can diflike. The 
 reafons why we fay that any affection or ac- 
 tion is neceflary, and why it is definite in 
 definite circumftances, are the very fame, and 
 cannot be diftinguimed in the mind. It is 
 the conjlant obfervation of its taking place in 
 thofe circumftances. 
 
 It is becaufe we fee that a clock always 
 
 ftrikes when the hands are in certain pofiti- 
 
 G 3 ons,
 
 86 A DEFENCE OF THE 
 
 ons, that we conclude it always will do fo, 
 and, therefore, neceffarily muft do fo, or that 
 (whether it be known or unknown to us) 
 there is a caufe why it cannot be otherwife. 
 Now, can you help applying this mode of 
 reafoning, and, confequently, this phrafeo- 
 logy, to the mind, and even the divine mind, 
 and, at the fame time, be free from weak 
 and unworthy prejudices ? For, if the will 
 cannot aft but when motives are prefent to 
 it, and if it always determines definitely in 
 definite circumftances with refpecl: to mo- 
 tives, you cannot but conclude that there is 
 a fufficient reafon, known or unknown to 
 you, why it muft be fo, and you can have no 
 reafon to fuppofe that it ever can be other- 
 wife. ; And, in this cafe, whether you fcru- 
 ple to fay, that fuch a determination can be 
 called atfion, or be faid to be neceffary, your 
 ideas of the things are the fame. (If any thing 
 always will be fo, there can be no good rea- 
 fon why we ftiould fcruple to fay that it 
 muft, and mujl neceffarily be foA
 
 DOCTRINE OF NECESSITY. 87 
 
 The Divine Being, you will allow, not- 
 withftanding the incomprehenfibility of his 
 nature, always adls definitely in definite cir- 
 cumitances. It would be a weaknefs and 
 imperfection to do otherwise. In fact, it is 
 no more a degradation of him to fay that 
 he acts neceffhrily, than that his eflence may 
 be termed fubftance, or being, in common 
 with that of the human mind, or even that 
 of wood and ftone. 
 
 You will fay, and juftly enough, that this 
 obfervation applies to the Divine Being only 
 as actually exifting y and operating; and that 
 originally, and befo/e the creation, when 
 there were no external circumftances by 
 which his actions could be determined, his 
 volitions mud have been, in the proper and 
 flrict philofophical fenfe of the word, free. 
 But then there never can have been a time, 
 to which that obfervation applies, becaufe 
 there never can have been any time in which 
 the Deity did not exift, and confequently a&. 
 G 4 For,
 
 88 A DEFENCE OF THE 
 
 For, fuppofing him not to have been em- 
 ployed in creation, &c. (which, however, I 
 think we can hardly avoid fuppofmg) he 
 muft at leaft have thought , and thinking, you 
 will not deny to be the adding of the mind. 
 The origin of adlion, therefore, in your fenfe 
 of the word, that is, the origin of felf-de- 
 termination, is the fame as the origin of the 
 Deity, concerning which we know nothing 
 at all. 
 
 Befides, how can you, or any of Dr. 
 Clark's admirers, think it any degradation to 
 
 tf 
 
 the Deity, that he mould aft necefTarily, 
 when you allow that he exifts neceflarily ? Is 
 not the term juftas opprobrious in the one 
 cafe as in the other ? ) Nay, might it not ra- 
 ther be fuppofed, by analogy, that the actions 
 of the being whofe existence is necefTary, 
 muft be necefTary too. With refpecl: to your 
 notion of dignity and honour, I would afk, Is 
 not the exigence of any being or thing, of as 
 much importance to him, as his afting? Is 
 
 not
 
 DOCTRINE OF NECESSITY. 89 
 
 not then his being fubject to neceflity as great 
 a reflexion upon him in the former cafe as in 
 the latter ? In mort, every thing that you 
 conlider as degrading and vilifying' \n man, on 
 account of his being fubject to neceflity, in 
 his exiftence or a&ions, might, if I were dif- 
 pofed to retort fo trifling and miftaken a con- 
 fideration, be applied to the Divine Being 
 himfelf. What I now obferve is only to 
 take off the force of your prejudice againft 
 the doftrine of neceflity, on account of its 
 exhibiting man, as you fuppofe, in a degra- 
 ding and unimportant light. 
 
 THE
 
 90 A DEFENCE- OF THE 
 
 THE CONCLUSION. 
 
 DEAR SIR, 
 
 1HAVE now gone over all the topicks that 
 I think of much importance to difcufs 
 with you. I might have taken a much larger 
 compafs ; but I was unwilling to take in 
 more objedts than fuch as I thought I might 
 poffibly throw fome new light upon. As to 
 what you fay concerning the doctrine of the 
 fcriptures, and feveral other articles, I leave 
 the field open to you, being fully fatisfied 
 with what I have already advanced, and ha- 
 ving nothing material to add to it. 
 
 You will probably think there is an ap- 
 pearance of arrogance in the tone of this let- 
 ter.
 
 'DOCTRINE OF NECESSITY. 91 
 
 ter. But in this, I think, you will do me 
 injuftice; my manner of writing being no- 
 thing more than what neceiTarily arifes from 
 the fullnefs of my perfuafion concerning the 
 truth and importance of the doctrine I con- 
 tend for ; and this, I think, is not greater 
 than your own. But in this I muft appeal 
 to indifferent perfons, if any fuch there be, 
 who will give themfelves the trouble to read 
 what we have written. 
 
 We all fee feme things in fo clear and 
 flrong a light, that, without having any high 
 opinion of our own understandings, we think 
 we may challenge all the world upon them. 
 Such all perfons will think to be moft of the 
 proportions of Euclid, and fuch, I dare fay, 
 with you are many tenets in theology. You 
 would not helitate, I prefume, to maintain 
 that bread and wine cannot be Jlejh and blood, 
 againft even a Bofluet, or a Thomas Aquinas, 
 than whom, it is probable, the world never 
 produced a greater man ; and that three per- 
 
 Jons,
 
 92 A DEFENCE OF THE 
 
 fonsy each pofTeffed of all the attributes of God, 
 muft make more in number than one God, 
 againft all the divines that the three churches 
 of Rome, England, and Scotland, could name 
 to hold the difputation with you. And, 
 though it fhould be deemed, as by them it 
 certainly would be, the height of arrogance 
 in you to hold out this challenge, it would 
 not give you any difturbance ; nor, in fad:, 
 would you think very highly of yourfelf, 
 though you mould gain a decided victory in 
 fuch a conteft. 
 
 Now, this happens to be my cafe with re- 
 fpect to^the doctrine of Neceffity. I really 
 think it the cleareft of all queftions, the truth 
 of it being as indubitable as that the three an- 
 gles of a right-lined triangle are equal to two 
 right angles, or that two and two make four, 
 and, therefore, I have no feeling either of 
 fear or arrogance, in challenging the whole 
 world in the defence of it/) This argument 
 I compare to fuch ground as one man may 
 
 defend
 
 DOCTRINE OF NECESSITY. 93 
 
 defend againft an army. It is, therefore, ab- 
 folutely indifferent to me by whom, or by 
 how many, I be affailed. You would, proba- 
 bly, fay the fame with refpect to the doctrine 
 of Liberty, at leaft the ftyle in which your 
 book is written feems to fpeak as much ; and 
 yet I by no means think you deficient in 
 modefty, any more than I do in underftand- 
 ing and ability. I only wifh, therefore, that, 
 notwithftanding the confidence with which 
 I have written, you would put the fame 
 candid conftruction on my conduct, that I 
 do on yours. 
 
 I make allowance for our difference of 
 opinion, on account of the different lights in 
 which we happen to fee things, or in which 
 they have been reprefented to us ; nor do I 
 at all expect that any thing I have now ad- 
 vanced, or am capable of advancing, will 
 make the leaft change in your view of things. 
 A change in things of fo much moment, 
 which would draw after it a thoufand other 
 
 changes,
 
 94 A DEFENCE OF THE 
 
 changes, is not to be expected either in you 
 or myfelf, who are both of us turned forty, 
 and who were, I fuppofe, metaphyficians be- 
 fore twenty. Judging of ourfelves by other 
 men, we mud conclude that our prefent 
 general fyftem of opinions, whether right or 
 wrong, is that which we {hall carry to our 
 graves. Thofe who are younger than we are, 
 and whofe principles are not yet formed, are 
 alone capable of judging between us, and of 
 forming their opinions accordingly -, and in 
 that refpeft, they may derive an advantage 
 from thefe publications that we cannot de- 
 rive from them ourfelves. 
 
 We fee every day fuch inftances of con- 
 jinned judgments in things of the greater!, as 
 well as of the leaft moment, as ought to make 
 the moil confident of us to paufe, though 
 every man is neceflarily determined by his 
 own view of the evidence that is before him. 
 I am well aware that, let me place the evi- 
 dence for the doctrine of neceffity in the 
 
 ilrongefl
 
 DOCTRINE OF NECESSITY. 95 
 
 ftrongeft anJ tleareft light that I poffibly can, 
 arguing either from the nature of the will, ob- 
 fervations on human life, or the conlideration 
 of the divine prefcience ; let me defcribe the 
 doctrine of imaginary liberty as a thing ever 
 fo abfurd, and impoffible in itfelf, as totally 
 foreign to, and inconfiftent with all princi- 
 ples of juft and moral government, and fup- 
 plying no foundation whatever for praife or 
 blame, reward or punimment -, the generality 
 of my readers will never get beyond the very 
 threfhold of the bufmefs. They will flill fay, 
 " Are we not confcious of our freedom, can- 
 " not we do whatever we pleafe -, fit ftill, walk 
 " about, converfe, or write, juft as we are dif- 
 " pofed ?" and they will fancy that all my 
 reafoning, plaufible as it may feem, cannot, in 
 fact, deferve any attention ; and even though 
 they mould be iilenced by it, they will not be 
 the nearer to being convinced. 
 
 But juft fo we fee it to be in politics. Let

 that determined you to reply to the firfl.

 any hope of prevailing upon a perfon fo

 while I think there is any reafonable prof- 
 pedt, that, by continuing a friendly contro- 
 verfy, any of the difficulties attending the 
 fubjecl: may be cleared up. The queftion 
 .before us is truely momentous, the argu-

 be very plain, your objections appear to me 
 to admit of fufficiently eafy anfwers *, and,

 "yOU complain of me for having mifre- 
 prefented your meaning, when what 
 you affert on the occafion, in my opinion, 
 confirms my reprefentation. I faid that you 
 fuppofed the mind capable of determining 
 contrary to any motive whatever, or, as I af- 
 terwards exprefs it, either without, or con- 
 trary to motives. You reply, p. 24, " I ne- 
 " ver faid, or fuppofed, that a rational being 
 *' can acl: without any motive, good or 
 f< bad 5 but the moft that I ever faid was, 
 " that, in the very fame circumftances, in 
 " which the choice, or determination of 
 "-the mind, was directed to one objed: of 
 " purfuit, it might have brought itfelf to 
 " will or determine on the purfuit of a 
 " different and contrary one." 
 
 Now
 
 DOCTRINE OF NECESSITY. $ 
 
 No"w where is the real difference between 
 my ftating of the cafe and yours ? You fay 
 you make choice of one object of purfuit, 
 for which, by your prefent confeffion, you 
 mult have "h^fome motive; and yet might 
 have taken a different and contrary one. 
 But how could you do this, without adt- 
 ing againft the motives which led you to 
 prefer the other ? If you admit that we ne- 
 ver aft but with the ftrongeft motives, as 
 well as never without fome motive (and 
 one of thefe feems to be the neceflary confe- 
 quence of the other) you muft, in this cafe, 
 have adted againft the ftrongeft motive. And, 
 if for this poflible determination there was 
 no motive at all (and if it was overbalanced 
 by other motives, it was, in fact* no mo- 
 tive at all) you muft have aclicd without any 
 motive for what you did, as well as againft 
 motives to the contrary.

 mean by necejfity, in any cafe, is the caufe 
 of certainty, or of univerfality ; and that 
 this is applicable to things cerporeal or men- 
 tal, without distinction j that the reafon, 
 and the only reafon, why we fay a ftone 
 falls to the ground necejfarily, is that it con- 
 ftantly and universally does fb ; and there- 
 fore that, if the determination of the mind 
 'be always according to motives, the dif- 
 
 ference
 
 DOCTRINE OF NECESSITY. 7 
 
 ference as I faid p. 23, cannot be in the 
 reality, but in the kind of the neceffity. 
 " The neceffity rauft be equally ftrict and 
 i* abfolute in both cafes, let the caufes of 
 " the neceffity 'by ever fo different." 
 
 This argument I faid you had not 
 given fufficient attention to. But you now 
 tell me, p. 7, " You were fo far from over- 
 " looking it, that you regarded it as the 
 " bafis on which my argument for the ne- 
 " ceflary determination of the mind refled, 
 " but that you confidered," p. 8. " that 
 " what you had infifted on to eftablifh the 
 *' diftinclion between phyfical and moral 
 " neceffity, as really replying to this very 
 " argument," and you refer me to p. 49, 
 &c. of your treatife. 
 
 Now I have carefully read over thofe 
 pages, but I am very far from finding in 
 them any thing to juftify your reference. 
 Becaufe, admitting the diftindion you con- 
 tend for between phyjical and moral necef-

 fity, ftill it is a neceflity, and if neceffity 
 have any meaning at all, it is that, while 
 the laws of nature are what they are, the 
 event denominated necefTary could not have 
 been otherwife. 
 
 You fay, p. 50, " We may multiply ever 
 " fo many other caufes, or circumftances, 
 " concurring with and leading to the choice 
 " that is made, it is plain they can only 
 " operate as moral, not as pbyjical caufes." 
 But to what purpofe is the diftin$:ion of 
 phyfical and moral, if they be real caufes, 
 when all real caufes muft, in given circum- 
 ftances; produce real and conftant effeds ?

 " They may "be," you fay, " occafions,

 " do not form, or necejjitate the determi-

 but if, in fact, the mind never does deter-

 motives, occafions, or grounds, there is no- 
 thing in any received mode of reafoning 
 
 that

 have determined otherwife, or that, ac*.

 felf determining power, that is, a cafe in 
 which we admit a real power without hav- 
 ing ever feen its effefts. All our rules of 
 reafoning in philofophy would be violated 
 by fuch a proceeding. Effects are the only 
 evidences of powers, of caufes -, and the 
 immediate confequence of t)iis is, that if 
 no event ever does take place, we . can have 
 no reafon to believe that it can take place. 
 This is as eaiily applicable to the cafe be-

 diftindtions of it, is -fo- manifestly unfatisfac-

 tion to the argument. <T afferted that if the

 fenfe of the word, certain y all the fame

 I will admit to be as many as you 
 plcafe) can fignifyj if, as you allow, the 
 refuti," ' invariably the fame. This is 
 certainly a cafe to which you cannot have 
 given fufficient attention, or you could not 
 treat it fo lightly as you do. I (hall, therefore 
 open, and expand it a little for you, to 
 give you an opportunity of feeing more 
 diflinctly what it is that you do admit, when

 of all kinds, are, likewife altogether in- 
 dependent of himfelf. It is no matter 
 when, you fay, that his frft proper volition 
 takes place, for you muft admit it is, in cer- 
 tain definite circumftances, independent of 
 himfelf. His determination, therefore, be- 
 ing by the hypothefis, certain, or definite in 
 thofe circumstances, whatever it be, it 
 brings him into other, but definite, circum- 
 ftances ,- whether forefeen or . unforefeen 
 by himfelf depends upon his judgment or 
 fagacity. In thefe new circumftances, he 
 makes another definite choice, or de-

 termination, concerning the new objects 
 that are now before him ; and this new 
 determination brings him into other new 
 circumftances. And thus his whole life 
 paffes in a conftant fucceffion of circum- 
 ftances and determinations, all infeparably 
 connected, till you come to the laft de- 
 termination of all, immediately preceed- 
 
 ing the extinction of all his powers by 
 death.

 my .own principles, it is all that I want, 
 call it by what name you pleafe. You 
 happen to like the word certain, whereas 
 I prefer the word neceffary-, but our ideas 
 muft be the very fame. We both chalk 
 *fcut a definite path .for every man to walk 
 in, from the commencement of his life to 
 the termination of it. The path is the 
 fame, drawn by the fame line, and by the 
 fame rule. It is a path that you admit 
 no man ever gets out of j and this, I do 
 allure you, is all that I mean, if I know 
 my own meaning, when I fay he never can 
 get out of it : for the laws of his na-

 hypothecs) not be definite in definite cir- 
 cumftances, before he can get out of it, 
 from his birth to his death.

 t ftill remains, if the certainty with which 
 " he acts be only a moral certainty, where- 
 " as by that which is phyjkal'tf. isdsftroy- 
 " ed." But if you reflect a moment, you 
 will perceive, that this is inconliftent with 
 what you jufl before granted. Becauie if, 
 in any cafe, the determination might have 
 been otherwife than it is, it would not 
 have been certain, but contingent. Cer- 
 tainty undoubtedly excludes all pojjibk va- 
 riety, for that implies uncertainty. Belides, 
 as I obferved before, and I cannot repeat it 
 too often, till I enfure your attention to it, 
 what proof or evidence can you produce of 
 the reality or exiftence of any power > that 
 is never exerted. If, therefore, you allow 
 that all determinations whatever are certain, 
 being directed by motives, what evidence 
 can there be of a power to act contrary to 
 motives ?

 did not exiil,viz. a different difpojition of mind, 
 in confequence of which his love of apples 
 would have been lefs, or his fear of punifh-

 it be not &faft> that human volitions depend 
 upon the previous difpolition of their minds 
 and the circumftances in which they are

 circumftances; and therefore whether, in 
 propriety of language, it mould not be faid 
 that they are always, and neceflarily, de- 
 termined by thofe circumftances, or motives.

 been aware, that this is directly inconfiftent 
 with your own fuppofition, viz. the deter- 
 mination being definite ; for if it might 
 have been otberivife, it would have been 
 indefinite. No man can be confcious of an

 Befides, reflect a little what is it of which

 IN the paffage to which you have no,w 
 referred me, in your former treatife, p. 50, 
 you lay great flrefs on the effential differ- 
 ence between the nature of the will, and 
 that of the judgment. " The will, you fay, 
 C 2 " implies
 
 2O A DEFENCE OF THE 
 
 " implies, in its very nature, a freedom 
 " from all controlling necelTary influence. 
 " It is the power of felf determination be- 
 " longing to an agent, the phyfical inde- 
 " pendency of which on any thing foreign 
 " to itfelf makes it to be what it is, or 
 " conftitutes its very eflence. The differ- 
 ft ent mode of operation belonging to the 
 " will," p. 52, " as diftincl: from the 
 " other faculties of the mind, arifes out 
 " of its different nature. The will is an 
 " independent, active principle, or faculty. 
 " The other faculties are dependent and 
 " merely paffive, &c." 
 
 .V XI : O'I'T' "^2" 
 Now I rather wonder that, in all this 
 loftinefs of language, you mould not have 
 perceived, that you are taking for granted 
 the very thing in difpute. If we judge of 
 the powers and faculties of man by his 
 attions (and what can we reafon but from 
 what we know) we muft conclude that he 
 is not pofleiTed of any fuch faculty as you 
 defcribe. On the contrary, we fee all men 
 
 without
 
 DOCTRINE OF NECESSITY. 21 
 
 without exception, driven to and fro, juft 
 as their circumftances and motives impel 
 ,them, without ever once exerting (as far 
 as appears) a fingle act of proper felf de- 
 termination. In all cafes of fufficient mag- 
 nitude, and in which there is fufficient op- 
 portunity given us to examine them, we 
 fee very plainly, that men are actuated by 
 very determinate motives , and we are here, 
 
 as in other fimilar cafes, authorized to 
 judge of obfcure cafes by thofe which are 
 more diftinet and evident, of the fame kind. 
 
 Befides, fo far am I from perceiving any 
 fuch eifential difference as you defcribe be- 
 
 X/ * 
 
 tween the 'will and the judgment, that I 
 perceive a remarkable refemblance between 
 them, and in that very refpect in which 
 you flate them to differ the moft. Does 
 the judgment decide according to the ap- 
 pearance of objects ? So does the will; and 
 if we confult fact, in no other way ; info- 
 much, that the will itfelf, exclufive of the 
 actions, or motions, that follow the will, may 
 
 C 3 not
 
 22 A DEFENCE OF. THE 
 
 not be improperly called z particular judg- 
 ment, deciding on the preferablenefs of ob- 
 jects, according to their appearances, which 
 are often very deceitful. For, judging by 
 whatever rule you pleafe, whatever object, 
 at the moment of determination, appears 
 preferable, that we always chufe. If, there- 
 fore, as I have faid before, there be a 
 power of felf determination in the will, I 
 I fhould expect to find the fame in the 
 judgment alfo, and if you will diftinguifh 
 them, in the judgment preferably to the 
 will ; if that may be called judgment which 
 decides, tho' concerning the preferablenefs of 
 objects. And there is no reafon why this 
 fhould not be the province of judgment, 
 properly fo called, as well as that of decid- 
 ing concerning the truth of objects. 
 
 You object to the conclufivenefs of my 
 reafoning, p. 18, to prove that from one 
 of your arguments it would follow that 
 judgment and volition were the fame thing, 
 and the fame with the circulation of tht 
 l blood,
 
 DOCTRINE OF NECESSITY. 23 
 
 bloed, &c. fuppoling that it goes on the idea 
 of judgment being an aft of the mind, only 
 in the popular fenfe of the word. Now I 
 will (hew you that my inference was truly 
 drawn, independent of any fuch definition 
 of the word, as will appear by leaving out 
 the word aft altogether. You will then fay, 
 p. 80, " Can that be truly faid to be my 
 '* 'volition, which is produced \syjbmetbing 
 " over 'which I had no power. On that 
 " ground, every thing that takes place in 
 " my body, as well as in my mind, may, 
 " with equal propriety, be called my yo- 
 " lition ; and fo the circulation of the blood, 
 " and \hepulfation of the heart, may, with 
 <e equal reafon, be called my volitions." 
 
 The medium of your proof, or the mid- 
 dle term in your fyllogifm, is not an aft, 
 but fomet king over which we have no power. 
 But, though the circulation of the blood, &c. 
 mould, upon the doctrine of neceliity, agree 
 with volition, in being a thing over which 
 we have no power, it does not, in that 
 C 4 refpect,
 
 24 ADEFENCEOFTHE 
 
 refpeft, agree .with volition only, but with 
 judgment alfo, and every other affection of 
 the mind. 
 
 I may perhaps make the inconclufivenefs 
 of your argument more apparent, by reduc- 
 ing it to the form of zfyllogifm, and framing 
 another exactly fimilar to it. Your argument 
 will then fland as follows. " According to 
 " the neceiTarians, . 
 
 " Volition is a thing over which a man 
 
 " has no power. 
 " But the pulfation of the heart is a 
 
 *' thing over which a man has no 
 
 " power. 
 
 " Ergo, The pulfation of the heart is a 
 volition." 
 
 A fyllogifm exactly parallel to this of 
 yours is the following : 
 
 A goofe is an animal that has two feet. 
 But a man is an animal that has two 
 
 feet. 
 Ergo, A man is a goofe. 
 
 But
 
 DOCTRINE OF NECESSITY.' 
 
 I am forry to have occafion to recall 
 to your attention the firil principles of 
 logick, but it is plain you had over- 
 looked them, when you thought you had 
 reduced the neceffarian to acknowledge that, 
 on his principles, the circulation of the blood, 
 and \hzpulfationof the heart, muft be termed 
 volitions. You meant to turn our princi- 
 ples into ridicule, and muft take the con- 
 fequence if the ridicule rebound upon your- 
 felf. You certainly had the merit of 
 attempting fomething new in this, but 
 there is always fome hazard in attempting 
 novelties.

 ADEFENCEOF THE 
 
 SECTION VI. 
 
 Of the Argument from the fuppofed CONSE- 
 QUENCES of the Doftrine of NeceJ/ity. 
 
 TO my objection to your reafoning 
 from the confequences of the dodtrine 
 of neceflity, you reply, p. 4, " There are con- 
 " fequences that feem greatly to out weigh 
 " all fpeculative reafonings of every fort 
 " which can be thought of, and incon- 
 ce teftably prove that the dodrine which 
 " fuch confequences attend is not and 
 " cannot be, true." You add, that Dr. 
 Watts recommends the mode of arguing 
 from confequences, and that I myfelf have 
 adopted it. 
 
 Now this, fir, you do without making 
 proper diftin&ions, which Dr. Watts, in 
 
 the
 
 DOCTRINE OF NECESSITY. 
 
 the very pafTage which you have quoted, 
 might have taught you to make. He fays, 
 that " the falfe proportion muft be re- 
 " futed by mewing that an evident falfe- 
 " hood, or abfurdity, will follow from it," 
 which is the very thing that I did, when 
 I mewed that, in confequence of ad- 
 mitting your doctrine of liberty, you muft 
 fuppofe that effects take place without ade- 
 quate caufes, and that the Divine Being 
 could have no prefcience of human actions, 
 which the fcriptures every where fuppofe. 
 On the other hand, the confequences that 
 you draw from the doctrine of neceflity 
 only relate to things that you dijlike, and 
 abhor, and which have nothing to do with 
 truth. 
 
 Shew me that any falfehood, or abfur- 
 dity, as Dr. Watts fays, follows from the 
 doctrine of neceffity, and I mall not then 
 fay, that we muft acqiiiefce in it, and make the 
 beft we can of it. For it is abfolutely im- 
 poilible to acquiefce in an acknowledged 
 
 falfehood
 
 28 A DEFENCE OF THE 
 
 falfehood, as we may in a thing that we 
 merely cannot relijh. With refpedt to all 
 things that merely exite difgujl y befides that 
 it may be conceived, that the difguft may be 
 ill founded (and in this cafe it appears to 
 me to be manifeftly fo) it is well known 
 that there are many truths, and valuable 
 ones too, that are ungrateful, efpecially at 
 the firft propofal. 
 
 Now I challenge you to mew that any 
 proper falfehcod, or abjurdity, will follow 
 from the principles of neceffity, a thing 
 that I do pretend to with refpect to the 
 doclrine of liberty. And do not any more 
 fay, as you do now, p. 6, that " it is in 
 " the fame way of reafoning with that 
 " which I have ufed," that you have en- 
 deavoured to fupport the doctrine of li- 
 berty. By this time, I hope, you fee there 
 is a great difference between the two cafes.

 on the fubjedtof the dangerous confequences

 you fay, p. 17, was " that it tends to in- 
 '* difpofe a perfon for virtuous activity, 
 " and felf command, but that you fup- 
 " pofe the neceffarian to be a&ive enough 
 " in gratifying his irregular and vicious 
 " inclinations." Now I had no doubt of 
 your ivillingnefs to make a diflincl:ion in

 indolent to good, and at the fame time afifive

 to evil-, but nature, not being of the party, 
 makes no fuch diftinction ; fo that the cafe 
 you fuppofe is an impoffibility. 
 
 If the belief of the doctrine of necef- 
 fity has any operation at all, either to ac- 
 tivity, or ina&tvity, it muft refpedt all ends, 
 or objftts, asfucf>,'&nd without diftmdtion, 
 whatever they be, and can never operate 
 one way if a man's inclinations be virtu- 
 ous and another way if they be vicious. If 
 on the one hand, I believe that my ob- 
 ject will be accomplished, and my belief 
 lead me to overlook all means, and therefore 
 I give myfelf no trouble about it -, or if, on 
 the other, my belief of the neceffary con- 
 nection of means and ends be fuch as that 
 my exertions are redoubled ; ftill thefe dif- 
 ferent confequences refpect all objects alike, 
 and can never operate to the difadvantage 
 of virtue, but on the fuppofition that all 
 neceffarians, as fucb, either are more indif- 
 ferent to their own happinefs than other 
 men, or have lefs knowledge of the necef- 
 fary

 \If this was the cafe, furely you might, 
 confidering the length of time that has 
 elapfed lince the doctrine of neceflity was 
 firft propofed by Mr. Hobbes, and even 
 lince it has been fully eftablimed, as 1 
 may fay, by Dr. Hartley' (and before my

 rous advocates among men of letters) 
 
 have been able to colledl: fomething like

 YOU eagerly catch, p. 27, at a cafual, 
 and as you think, an improper expref- 
 fion of mine, when I faid that " the origin 
 " of action, or of felf determination, is 
 Sf the fame as the origin of the deity, con- 
 " cerning which we know nothing at all,'* 
 as if I really fuppofed the deity to have had 
 an origin, or a beginning. Whereas, be- 
 iides that you well know that I fuppofe, 
 juftas much as yourfelf, that the deity is 
 properly uncaufed, and confequently had no 
 origin, and therefore that it could be no 
 more than an inadvertent expreffion that you 
 had got hold of, I have, in fad:, faid the fame 
 thing in this very place, viz. that proper 
 adtion, or felf determination, can have no 
 beginning, becaufe it muft have commenced 
 with the deity, who had none. This triumph 
 
 of
 
 DOCTRINE OF NECESSITY. 33 
 
 yours, of which you feem willing to make 
 fo much, is, indeed premature. 
 
 If, in maintaining an opinion common to 
 rnyfelf and Dr. Price, I mould have faid, 
 that " the commencement of the creation 
 " was the fame with that of the deity him- 
 " felf ;" would not the obvious construction 
 have been, not that they both had a begin- 
 ning, but that neither of them had any? 
 In this cafe, alfo, I am juft as far from in- 
 timating, in the moft diftant manner, that 
 it was even pojjible for the deity to have 
 had any origin. I muft fay that this con- 
 ftruction of my words is very extraor- 
 dinary. 
 
 You charge me, p. 33, with having 
 mif-ftated Dr. Price's opinion on the fub- 
 ject of liberty, as well as your own $ but, 
 though I am not fenfible of having made 
 any miftake in this refpect, it is not a point 
 that I choofe to difcufs with you. It is fuf- 
 ficient for my prefent purpofe, if I truly

 v Here you muft give me leave to obferve, 
 tnat it was very improper, on feveral ac- 
 counts, to add the name of Dr. Price to 
 thofe of Locke, Wollafton, Clarke, and 
 Fofter, as authorities in favour of the doc- 
 trine of liberty, for whom I ought to have 
 had a greater reverence. I alfo could muf- 
 ter up a lift of very refpe&able authorities, 
 fuch as Collins, Leibnitz, Hutchefon, Ed-

 fons, I mould have chofen to have confined 
 it to the dead, and mould have omitted the 
 Jiving, efpecially the man with whom my 
 antagonift had a public and truly amicable 
 controverfy on the fubjedl:. Dr. Price, 
 however, I am well perfuaded, believes that 
 my refpect for him is not lefs than yours,

 you would not have voluntarily undertaken 
 the difcuilion of this argument with me, 
 without having well weighed your force in 
 it, and being determined to bring it to 
 fomething more like a proper dofe ; I hope 
 that, notwithftanding you fay you mall

 the mind is not an effect 'without a caufe, 
 though it be not produced by any motive, 
 becaufe \hzfelf -deter mining power itfelfis the 
 caufe. I replied, that, allowing this fuppofed 
 power to be the caufe of choice in general, 
 it can no more be confidered as the caufe of 
 any particular -choice, than the motion of the 
 air in general can be faid to be the caufe 
 of any particular wind -, becaufe all winds 
 are equally motions of the air, and there-

 and you know that necerlarians, though

 That you mould fay you had not parTed 
 over any thing of the argumentative kind in 
 my Letter, which feemed to require a reply, 
 and yet have overlooked this moft material 
 article, as well as many others, furprifes 
 me not a little. 
 
 On this fubjecl:, I alfo beg you would 
 not fail to give particular attention to the 
 fifth article of my Additional Illujirations, 
 printed in the correfpondence with Dr. Price, 
 p. 288, in which, I think I have proved 
 decifivdy, that the mind itfe/fc&n never be

 It was unfortunate for thefe Illuftratlons, 
 that they did not appear till after the great- 
 eft part of your firft treatife was written, 
 and yet fo long before your appendix, that 
 I fuppofe they were forgotten. Though, as 
 you had feen them before you wrote the 
 preface, and confequently fome time before 
 the publication of your firft piece, you had 
 a good opportunity of animadverting upon 
 them, and might be expected to do it in a 
 cafe that fo materially affected your main 
 argument. 
 
 You now fay, in general, that " now 
 " I have read them, they appear as little 
 " fatisfactory as the former ; and that to 
 " all which Dr. Prieftley has advanced in 
 " the correfpondence, Dr. Price appears 
 " to have given a very clear and fufficient

 of the mind being fubjecl: to any laws at

 can derive no advantage from the com-

 the existence of the felf determining power 
 you boaft fo much of, . I mean a proof 
 fromfatfj and not from a merely imagined 
 
 feeling, or confcioufnefs of it, which one 
 perfon may affert, and another, who is cer- 
 tainly constituted in the fame manner, may 
 deny. What I affert is, that all we can feel, 
 or be confcious of, in the cafe, is that our 
 actions, corporeal or mental, depend upon 
 our will, or pleafure ; but to fay that our 
 wills are not always influenced by motives, 
 is fo far from being agreeable, that it is 
 directly contrary to all experience in our- 
 felves, and all obfervation of others. 
 
 4. You have faid nothing to explain, or 
 foften your denial of the doctrine of divine 
 prefcience, which, as a chriftian, and a 
 chriftian minifter, it greatly behoves you 
 to do. You pretend to be mocked at the 
 confequences of the doctrine of neceffity, 
 which exift only in your own imagination ; 
 but here is a confequence of your doctrine 
 
 of
 
 42 ADEFENCEOFTHE 
 
 of liberty, dire&ly repugnant to the whole 
 tenor of revelation, as it has been under- 
 ftood by all who have ever pretended 
 to any faith in it, though they have dif- 
 fered ever fo much in other things. It 
 will be well worth your while to make 
 another appendix to your book, if it were 
 only to give fome little plaufibility t this 
 bufinefs, and either to mew, if you can, 
 that the divine prefcience is not a doctrine 
 of the fcriptures, or that the facred writers 
 were miftaken with refpect to it. Betides, 
 it is incumbent upon you to hew,' inde- 
 pendent of your profeiiion as a chriftian, 
 how, on your own principles, any fuch 
 government of the 'world as we fee to take 
 place could exiil. To fay, as you do, that 
 God, notwithftanding his want of prefci- 
 ence, may yet govern free beings in the 
 befl manner that free beings can be go- 
 verned, will avail you nothing j oecaufe I 
 maintain, that if liberty be what you de- 
 fine it to be, a power of proper felf-deter- 
 minatipn* fuch beings.omTwtf be governed at

 all. I have fhewn that it is impoffible they 
 mould ever be proper, fubj efts of moral 
 government. The Divine Being cannot 
 controul their actions ; the influence of all 
 motives (the only inftruments of moral 
 government) will be altogether uncertain ; 
 he can, form no judgment of their .effect ^ 
 and, in confequence, all. mufl be anarchy 
 and confuiion. 
 
 But I would rather advife you t 
 what you have too hafiily advanced. If 
 poffible, think of fome method of recon- 
 ciling prefcience with liberty ; and by no 
 means purchafe your liberty at fo very great 
 a price. At leaft be very Jure, in the firft 
 place, that it is worth fo much. 
 
 If, as I fuppofe will be the cafe, you 
 mould not be able to reconcile prefcience 
 with your more favourite dodrine of free- 
 will, be advifed bv me, rather than give 
 up the former fo lightly as you do, to keep 
 it at all events -, even though, in order to 
 
 do
 
 44 'A DEFENCE OF THE 
 
 do it, you fhould be obliged to rank it (as 
 many truly pious chriftians do the do&rines 
 of tranfubjlantiatkn and the trinity] among 
 the myfteries of faith, things to be held 
 facred, and not to be fubmitted to rational 
 inquiry. On no account would I abandon 
 fuch a doctrine as that of Divine preftienc e y 
 while I retained the leaft refpect for reve- 
 lation, or wilhed to look with any fatis-

 prefcience as a thing of fo little confequence, 
 the molt, truly candid thing I can fay is what 
 you have quoted, and endeavoured to expofe, 
 as the extreme of uncharitabhnefs when firft 
 advanced Jn my controverfy with Dr. 
 Beattie, on the fame ocean" on. . But becaufc 
 you. may think the figurative expreffion too 
 ftrong (though," in fd:d:, the ftronger it is 
 
 the

 the better apology it makes) I fhall fay the 
 fame thing in other words. " It is what

 " into. You are blind to the confequences,

 5. I particularly defire you would once 
 more go over with me the fubjed of the 
 practical influence of the doctrine of necef- 
 lity. This is far from being, in my opinion, 
 the dark fide of my argument. I love, 
 and rejoice in this view of it; confident, 
 and I hope I may add, feeling, that, when 
 rightly underftood, it is highly favourable 
 to every thing that is great and good in 
 man. Tell me whether the belief of the 
 certainty of the end, without any idea of 
 the nejcefTary connection of the means by 
 which it is brought about (which is the 
 doctrine of Cajvinifrn) does not work one 
 way, and the belief of the certainty of the 
 end, only as a confequence of its neceflary 
 connection with the previous means (which 
 
 is the doctrine ^T 'philosophical ncccflity)

 does not work another way. Re-perufe 
 my account of their different influences, 
 and mew, from a jufter view of the princi- 
 ples of human nature, that, with thofe 
 apprehenfions, men muft feel and atft dif- 
 ferently from what I have fuppofed they 
 naturally would do. 
 
 6. I like wife defire you would particu- 
 larly attend to what I have obferved in my 
 feventh feftion, with refpedt to the ufe of 
 the term agency and refponjibillty -, becaufe, 
 if what I have there obferved be juft, you, 
 and other defenders of the doctrine of 
 liberty can derive no advantage whatever 
 from any argument in which it is taken 
 for granted, that man, in your fenfe of the 
 terms, is an agent, and a refponjible being ; 
 as I mew, that the ftate of moral govern- 
 ment in which we are, is perfectly confift- 
 ent with, nay, pre-fuppofes the doclrine 
 of neceffity - y that for this purpofe it is fuf- 
 ficient that man be, in the popular fenfe of 
 the word only, and no.t in a fenfe that pre- 
 fuppofes
 
 48 ADEFENCEOFTHE 
 
 fuppofes the doctrine of liberty, an agent* 
 and refponjibk. Nay, I beg you would 
 fhew how man, conftituted as you fuppofe 
 him to be, can be a fubjecSt of moral govern- 
 ment at all. 
 
 7. As you lay great ftrefs on the feeling 
 of remorfe, I beg you would confider, and 
 reply to what I have urged on that fubje<5t, 
 in my letter to you, p. 62, and my addi- 
 tional illuftrations, p. 296. If my ftate of 
 the fad: be juft, no argument from that 
 topic can avail you any thing; every juft 
 view of that fubje<3: being extremely fa- 
 vourable, rather than unfavourable, to the 
 
 dodtrine of neceflity. 
 
 
 
 Pleafe to obferve that all thefe queries 
 relate to matters ftri&ly argumentative, or 
 that muft be allowed to have weight in 
 forming our judgment on the fubjecl: in 
 debate -, and do not pafs them over a fecond 
 time, as if they were things of another 
 nature, and fuch as you are under no obli- 
 gation

 gation to notice. Say, if you pleafe, and 
 prove it, if you can, that what I have ad- 
 vanced with refpecl: to them is inconchifive ; 
 but do not pafs them over in filence, as if 
 they were not of an argumentative nature, 
 or indeed, not very materially fo. 
 
 THE CONCLUSION. 
 
 DEAR SIR, 
 
 I Do not know that it is neceflary for me 
 to call your attention particularly to any 
 other points in con teft between us; but I 
 earneftly beg your explicit reply to thefe 
 few. Many controverfies have terminated 
 without effect, and without any advantage 
 to the caufe of truth, merely becaufe the 
 parties have not come to a fair iffue, but 
 have left their readers wihing to know 
 what the one or the other of them would 
 have replied to this or that argument, or to 
 E this
 
 $0 A DEFENCE OF THE 
 
 this or that ftate, or view of it. I wifh to 
 carry this controverfy to improper conchifion. 
 For my part, I will readily anfwer any 
 queftion you fhall think proper to propofe 
 to me, and mall do it without the lead 
 referve or evafion. You believe that I would. 
 I only beg that you would, in like manner, 
 reply to me. More, I think, is to be done 
 by diftindt interrogatories, and categorical 
 anfwer -s, than in any other manner. Let 
 us, however, try this method. A very few 
 more fhort pieces, which, with what we 
 have already published, would not make too 
 bulky afingle volume for each of us, might, 
 I think, exhaiiil all that we can now have 
 to fay that is material. Why then, when 
 the trouble will be fo little, and the ad- 
 vantage may be fo great, mould you decline 
 this bufinefs prematurely ? You have cer- 
 tainly as much leifure for the difcuffion as 
 I have ; and as it was you that called me 
 out, and not I that called upon you, I 
 mould imagine you have not lefs zeal in, 
 the caufe than myfelf,

 You cannot apprehend from me any thing 
 offenfive to you in my manner of writing, 
 any more than I can with refpect to you; 
 nor mall I take oTrencc~air little things* 
 You may make what reflections you^pleafe 
 on my temper or manner, and there are 
 points enow to hit in both, if you be fo 
 difpofed. You have my leave beforehand* 
 to fay that I am mfolent in one place, and 
 arrogant in another j and you may parody 
 my moft obnoxious paragraphs, whether 
 in the work you are anfwering, or out of it \ 
 if it will ferve to amufe yourfelf or your, 
 readers. If there be more of pleafantry 
 than ill-nature in your ftrictures, I wiU 
 chearfully bear it all, and with Themifto- 
 cles to Paufanias, fay, ftrike me, and as 
 often as you pleafe, but hear me> and an- 
 
 fwer me. 
 
 >. 
 
 Whatever I have been, or may be to 
 others, you mall have nothing to complain 
 of with refpect to yourfelf per finally -, and 
 I am fo happy to find myfelf engaged with 
 
 , a perfon
 
 A DEFENCE, &C. 
 
 a perfon of undoubted judgment in the 
 controverfy, that, I own, I am ve"ry un- 
 willing to part with you fo foon. I fhall be 
 like Horace's friend, and you mufl have 
 recourfe to as manymifts to get quit of me. 
 
 Hoping, therefore, to have the fatif- 
 fadlion of hearing from you again on the 
 fubject, and wiming your reply may be as 
 fpeedy as will be confident with its being 
 'well weighed, I am,
