PART VII.
BUT here,* continued PHILO, in examining the ancient system of the soul of the world, there strikes me, all on a sudden, a new idea, which, if just, must go near to subvert all your reasoning, and destroy even your first inferences, on which you repose such confidence. If the universe bears a greater likeness to animal bodies and to vegetables, than to the works of human art, it is more probable, that its cause resembles the cause of the former than that of the latter, and its origin ought rather tobe ascribed to generation or vegetation than to reason or design. Your conclusion, even according to your own principles, is therefore lame and defective.
Pray open up this argument a little farther, said DEMEA. ForI do not rightly apprehend it, in that concise manner, in which you have expressed it.
Our friendCLEANTHES, replied PHILO, as you have heard, asserts, that since no question of fact can be proved otherwise than by experience, the existence of a Deity admits not of proof from any other medium. The world, says he, resembles the works of human contrivance: Therefore its cause must also resemble that of the other. Here we may remark, that the operation of one very small part of nature, to wit man, upon another very small part, to wit that inanimate matter lying within his reach, is the rule, by which CLEANTHES judges of the origin of the whole; and he measures objects, so widely disproportioned, by the same individual standard. But to wave all objections drawn from this topic; I affirm, that there are other parts of the universe (besides the machines of human invention) which bear still a greater resemblance to the fabric of the world, and which therefore afford a better conjecture concerning the universal origin of this system. These parts are animals and vegetables. The world plainly resembles more an animal or a vegetable, than it does a watch or a knitting-loom. Its cause, therefore, it is more probable, resembles the cause of the former. The cause of the former is generation or vegetation. The cause, therefore, of the world, we may infer to be something similar oranalagous to generation or vegetation.
But how is it conceivable, said DEMEA, that the world can arise fromany thing similar to vegetation or generation?
Very easily, replied PHILO. In like manner as a tree sheds its seed into theneighbouring fields, and produces other trees; so the great vegetable, the world, or this planetary system, produces within itself certain seeds, which, being scattered into the surrounding chaos, vegetate into new worlds. A comet, for instance, is the seed of a world; and after it has been fully ripened, by passing from sun to sun, and star to star, it is at lasttost into the unformed elements, whichevery where surround this universe, andimmedialy sprouts up into a new system.
Or if, for the sake of variety (for I see no other advantage) we should suppose this world to be an animal; a comet is the egg of this animal; and in like manner as an ostrich lays its egg in the sand, which, without any farther care, hatches the egg, and produces a new animal; so.......I understand you, says DEMEA: But what wild, arbitrary suppositions are these? What data have you for such extraordinary conclusions?And is the slight, imaginary resemblance of the world to a vegetable or an animal sufficient to establish the same inference with regard to both?Objects, which are in general so widely different; ought they to be a standard for each other?
Right, cries PHILO:This is the topic on which I have all along insisted . I have stillasserted, that we have no data to establish any system of cosmogony. Our experience, so imperfect in itself, and so limitedboth in extent and duration , can afford us no probable conjecture concerning the whole of things.But if we must needs fix on some hypothesis; by what rule, pray, ought we to determine our choice? Is there any other rule than the greater similarity of the objects compared?And does not a plant or an animal, which springs from vegetation or generation, bear a stronger resemblance to the world, than does any artificial machine, which arises from reason and design?
But what is this vegetation and generation of which you talk, said DEMEA? Can you explain their operations, and anatomize that fine internal structure, on which they depend?
As much, at least, replied PHILO, as CLEANTHES can explain the operations of reason, or anatomize that internal structure, on which it depends. But without any such elaborate disquisitions, when I see an animal, I infer, that it sprang from generation; and that with as great certainty as you conclude a house to have been reared by design. These words, generation, reason, mark only certain powers and energies in nature, whose effectsare known , but whose essence is incomprehensible; and one of these principles, more than the other, has no privilege for being made a standard to the whole of nature.
In reality, DEMEA, itmay reasonably be expected , that the larger the views are which we take of things, the better will they conduct us in our conclusions concerning such extraordinary and such magnificent subjects. In this little corner of the world alone, there are four principles, Reason, Instinct, Generation, Vegetation, which are similar to each other, and are the causes of similar effects. What a number of other principles may we naturally suppose in the immense extent and variety of the universe, could we travel from planet to planet and from system to system, in order to examine each part of this mighty fabric? Any one of these four principlesabove mentioned (and a hundred others, which lie open to our conjecture) may afford us a theory, by which to judge of the origin of the world; and it is a palpable and egregious partiality, to confine our view entirely to that principle, by which our own minds operate. Were this principle more intelligible on that account, such a partiality might be somewhatexcuseable : Butreason, in its internal fabric and structure, is really as little known to us as instinct or vegetation; and perhaps even that vague,undeterminate word, Nature, to which the vulgar referevery thing , is not at the bottom more inexplicable .The effects of these principles are all known to us from experience: But the principles themselves, and their manner of operation are totally unknown: Not is it less intelligible, or less conformable to experience to say, that the world arose by vegetation from a seed shed by another world, than to say that it arose from a divine reason or contrivance, according to the sense in which CLEANTHES understands it.
But methinks, said DEMEA, if the world had a vegetative quality, and could sow the seeds of new worlds into the infinite chaos, this power would be still an additional argument for design in its author. For whence could arise so wonderful a faculty but from design?Or how can order spring fromany thing , which perceives not that order which it bestows?
You need only look around you, replied PHILO, to satisfy yourself with regard to this question. A tree bestows order and organization on that tree, which springs from it, without knowing the order: an animal, in the same manner, on its offspring: a bird, on its nest: and instances of this kind are even more frequent in the world, than those of order, which arise from reason and contrivance. To say that all this order in animals and vegetables proceeds ultimately from design, is begging the question; nor can that great point be ascertained otherwise than by proving a priori, both that order is, from its nature, inseparably attached to thought, and that it can never, of itself, or from original unknown principles, belong to matter.
But farther, DEMEA; this objection, which you urge, can never be made use of by CLEANTHES, without renouncing adefence , which he has already made against one of my objections. When I enquired concerning the cause of that supreme reason and intelligence, into which he resolveseverything ; he told me, that the impossibility of satisfying such enquiries could never be admitted as an objection in any species of philosophy. We must stop somewhere,says he; nor is it ever within the reach of human capacity to explain ultimate causes, or show the last connections of any objects. It is sufficient, if the steps,so far as we go, are supported by experience and observation. Now, that vegetation and generation, as well as reason,are experienced to be principles of order in nature, is undeniable. IfI rest my system of cosmogony on the former, preferably to the latter, 'tis at my choice. The matter seems entirely arbitrary.And when CLEANTHES asks me what is the cause of my great vegetative or generative faculty, I am equallyintitled to ask him the cause of his great reasoning principle.These questions we have agreed to forbear on both sides; and it is chiefly his interest on the present occasion to stick to this agreement. Judging by our limited and imperfect experience, generation has some privileges above reason: For we see everyday the latter arise from the former, never the former from the latter.
Compare,I beseech you, the consequences on both sides. The world, say I, resembles an animal, therefore it is an animal,therefore it arose from generation. The steps,I confess, are wide; yet there is some small appearance of analogy in each step. The world, says CLEANTHES, resembles a machine, therefore it is a machine,therefore it arose from design. The steps here are equally wide, and the analogy less striking.And if he pretends to carry on my hypothesis a step farther, and to infer design or reason from the great principle of generation, on which I insist; I may, with better authority, use the same freedom to push farther his hypothesis, and infer a divine generation ortheogony from his principle of reason. I have at least some faint shadow of experience, which is theutmost, that can ever be attained in the present subject. Reason, in innumerable instances,is observed to arise from the principle of generation, and never to arise from any other principle.
HESIOD, and all the ancient Mythologists,were so struck with this analogy, that they universally explained the origin of nature from an animal birth, and copulation. PLATO too,so far as he is intelligible, seems to have adopted some such notion in his TIMAEUS.
The BRAMINS assert, that the world arose from aninsinite spider, who spun thiswhole complicated mass from his bowels, and annihilates afterwards the whole or any part of it, by absorbing it again, and resolving it into his own essence. Here is a species of cosmogony, which appears to us ridiculous; because a spider is a little contemptible animal, whose operations we are never likely to take for a model of the whole universe.But still here is a new species of analogy, even in our globe.And were there a planet, wholly inhabited by spiders, (which is very possible) this inference would there appear as natural and irrefragable as that which in our planet ascribes the origin of all things to design and intelligence, as explained by CLEANTHES. Why an orderly systemmay not be spun from the belly as well as from the brain, it will be difficult for him to give a satisfactory reason.
I must confess, PHILO, replied CLEANTHES, that, of all men living, thetask which you have undertaken, of raising doubts and objections, suits you best, and seems, in a manner, natural and unavoidable to you. So great is your fertility of invention, thatI am not ashamed to acknowledge myself unable, on a sudden, to solve regularly such out-of-the-way difficulties as you incessantly start upon me: though I clearly see, in general, their fallacy and error.And I question not, but you are yourself, at present, in the same case, and have not the solution so ready as the objection; while you must be sensible, that common sense and reason is entirely against you, and that such whimsies as you have delivered, may puzzle, but never can convince us.
PART VIII.
WHAT you ascribe to the fertility ofmy invention, replied PHILO, is entirely owing to the nature of the subject. In subjects, adapted to the narrow compass of human reason, there is commonly but one determination, which carries probability or conviction with it; and to a man of soundjudgement , all other suppositions, but that one, appear entirely absurd and chimerical.But in such questions, as the present, a hundred contradictory views may preserve a kind of imperfect analogy;* and invention has here full scope to exert itself. Without any great effort of thought, I believe that I could, in an instant, propose other systems of cosmogony, which would have some faint appearance of truth; though it is a thousand, a million to one, if either yours or any one of minebe the true system.
Forinstance; what if I should revive the old EPICUREAN hypothesis? This is commonly, and I believe, justly, esteemed the most absurdsystem, that has yet been proposed; yet, I know not, whether, with a few alterations, it might not be brought to bear a faint appearance of probability. Instead of supposing matter infinite, as EPICURUS did; let us suppose it finite. A finite number of particlesis only susceptible of finite transpositions: and it must happen, in an eternal duration, that every possible order or position must be tried an infinite number of times. This world,therefore, with all its events, even the most minute, has before been produced and destroyed, and will again be produced and destroyed, without any bounds and limitations. No one, who has a conception of the powers of infinite, in comparison of finite, will ever scruple this determination.
But this supposes, said DEMEA, that matter can acquire motion, without any voluntary agent or first mover.
And where is the difficulty, replied PHILO, of that supposition? Every event, before experience, is equally difficult and incomprehensible; and every event, after experience, is equally easy and intelligible. Motion, in many instances, from gravity, from elasticity, from electricity, begins in matter, without any known voluntary agent; and to suppose always, in these cases, an unknown voluntary agent, is mere hypothesis; and hypothesis attended with no advantages. The beginning of motion in matter itself is as conceivable a priori as its communication from mind and intelligence.
Besides; why may not motion have been propagated by impulse through all eternity, and the same stock of it, or nearly the same, be still upheld in the universe? As much as is lost by the composition of motion, as muchis gained by its resolution.And whatever the causes are, the fact is certain, that matter is, and always has been in continual agitation, as far as human experience or tradition reaches. There is not probably, at present, in the whole universe, one particle of matter at absolute rest.
And this very consideration too, continued PHILO, which we have stumbled on in the course of the argument, suggests a new hypothesis of cosmogony, that is not absolutely absurd and improbable. Is there a system, an order, anoeconomy of things, by which matter can preserve that perpetual agitation, which seems essential to it, and yet maintaina constancy in the forms, which it produces? There certainly is such anoeconomy : for this is actually the case with the present world. The continual motion of matter, therefore, in less than infinite transpositions, must produce thisoeconomy or order; and by its very nature, that order, when once established, supports itself, for many ages, if not to eternity.But where-ever matter is sopoized , arranged, and adjusted as to continue in perpetual motion, and yet preserve a constancy in the forms, its situation must, of necessity, have all the same appearance of art and contrivance, which we observe at present.All the parts of each form must have a relation to each other, and to the whole: and the whole itself must have a relation to the other parts of the universe; to the element, in which the form subsists; to the materials, with which it repairs its waste and decay; and to every other form, which is hostile or friendly. A defect in any of these particulars destroys the form; and the matter, of which it is composed, is again set loose, and is thrown into irregular motions and fermentations, till it unite itself to some other regular form. If no such form be prepared to receive it, and if there be a great quantity of this corrupted matter in the universe, the universe itself is entirely disordered; whether it be the feeble embryo of a world in its first beginnings, that is thus destroyed, or the rotten carcass of one, languishing in old age and infirmity. In either case, a chaos ensues;till finite, though innumerable revolutions produce at last some forms, whose parts and organs are so adjusted as to support the forms amidst a continued succession of matter.
Suppose, (for we shallendeavour to vary the expression) that matter were thrown into any position, by a blind, unguided force; it is evident that this first position must in all probability be the most confused and most disorderly imaginable, without any resemblance to those works of human contrivance, which, along with a symmetry of parts, discover an adjustment of means to ends and a tendency to self-preservation. If the actuating force cease after this operation, matter must remainfor ever in disorder, and continue an immense chaos, without any proportion or activity.But suppose, that the actuating force, whatever it be, still continues in matter, this first position will immediately give place to a second, which will likewise in all probability be as disorderly as the first, and so on, through many successions of changes and revolutions. No particular order or position ever continues a moment unaltered. The original force, still remaining in activity, gives a perpetual restlessness to matter. Every possible situationis produced, and instantly destroyed . If a glimpse or dawn of order appears for a moment, itis instantly hurried away and confounded, by that never-ceasing force, which actuates every part of matter .
Thus the universe goes on for many ages in a continued succession of chaos and disorder.But is it not possible that it may settle at last, so as not to lose its motion and active force (for that we have supposed inherent in it) yet so as to preserve an uniformity of appearance, amidst the continual motion and fluctuation of its parts? This we find to be the case with the universe at present. Every individual is perpetually changing, and every part of every individual, and yet the whole remains, in appearance, the same.May we not hope for such a position, or rather be assured of it, from the eternal revolutions of unguided matter, and may not this account for all the appearing wisdom and contrivance, which is in the universe? Let us contemplate the subject a little, and we shall find, that this adjustment, if attained by matter, of a seeming stability in the forms, with a real and perpetual revolution or motion of parts, affords a plausible, if not a true solution of the difficulty.
It is in vain, therefore, to insist upon the uses of the parts in animals or vegetables and their curious adjustment to each other. I would fain know how an animal could subsist, unless its parts were soadjusted? Do we not find, that it immediately perishes whenever this adjustment ceases, and that its matter corrupting tries some new form? It happens, indeed, that the parts of the world are so well adjusted, that some regular form immediately lays claim to this corrupted matter: and if it were not so, could the world subsist? Must it not dissolve as well as the animal, and pass through new positions and situations; till in a great, but finite succession, it fall at last into the present or some such order?
It is well, replied CLEANTHES, you told us, that this hypothesiswas suggested on a sudden, in the course of the argument. Had you had leisure to examine it, you would soon have perceived the insuperable objections, to which it is exposed. No form, you say, can subsist, unless it possess those powers and organs, requisite for its subsistence: some new order oroeconomy must be tried, and so on, without intermission; till at last some order, which can support and maintain itself, is fallen upon.But according to this hypothesis, whence arise the manyconveniencies and advantages, which men and all animals possess? Two eyes, two ears, are notabsolutely necessary for the subsistence of the species. Human racemight have been propagated and preserved, without horses, dogs, cows, sheep, and those innumerable fruits and products, which serve to our satisfaction and enjoyment . If no camelshad been created for the use of man in the sandy deserts of AFRICA and ARABIA, would the world have been dissolved? If no loadstonehad been framed to give that wonderful and useful direction to the needle, would human society and the human kind have been immediately extinguished? Though the maxims of Naturebe in general very frugal, yet instances of this kind are far from being rare; and any one of them is a sufficient proof of design, and of a benevolent design, which gave rise to the order and arrangement of the universe.
At least, you may safely infer, said PHILO, that the foregoing hypothesis is so far incomplete and imperfect; whichI shall not scruple to allow.But can we ever reasonably expect greater success in any attempts of this nature?Or can we ever hope to erect a system of cosmogony, that will be liable to no exceptions, and will contain no circumstance repugnant to our limited and imperfect experience of the analogy of Nature? Your theory itself cannot surely pretend to any such advantage; even though you have run intoAuthropomorphism , the better to preservea conformity to common experience. Let us once more put it to trial. In allinstances which we have ever seen, ideas are copied from real objects, and are ectypal, not archetypal, to express myself in learned terms: You reverse this order, and give thought the precedence. In allinstances which we have ever seen, thought has no influence upon matter, except where that matter is so conjoined with it, as to have an equal reciprocal influence upon it. No animal can move immediatelyany thing but the members of its own body; and indeed, the equality of action and re-action seems to bean universal law of Nature: But your theory implies a contradiction to this experience.These instances, with many more, which it were easy to collect, (particularly the supposition of a mind or system of thought that is eternal, or in other words, an animalingenerable and immortal) these instances, I say, may teach, all of us, sobriety in condemning each other; and let us see, that as no system of this kind ought ever to be received from a slight analogy, so neither ought any to be rejected on account of a small incongruity. For that is an inconvenience, from which we can justly pronounce no one to be exempted.
All religious systems, it is confessed, are subject to great and insuperable difficulties. Each disputanttriumphs in his turn; while he carries on an offensive war, and exposes the absurdities, barbarities, and pernicious tenets of his antagonist. But all of them, on the whole, prepare a complete triumph for theSceptic ; who tells them, that no system ought ever to be embraced with regard to such subjects: For this plain reason, that no absurdity ought ever to be assented to with regard to any subject. A total suspense ofjudgement is here our only reasonable resource. And if every attack, as is commonly observed, and nodefence , among Theologians, is successful; how complete must be his victory, who remains always, with all mankind, on the offensive, and has himself no fixed station or abiding city, which he is ever, on any occasion, obliged todesend ?
PART IX.
BUT if so many difficulties attend the argument a posteriori,* said DEMEA; had we not better adhere to that simple and sublime argument a priori, which, by offering to us infallible demonstration, cuts off at once all doubt and difficulty? By this argument too, we may prove the INFINITY of the divine attributes, which,I am afraid, can never be ascertained with certainty from any other topic. For how can an effect, which either is finite, or, for aught we know, may be so; how can such an effect,I say, prove an infinite cause? The unity too of the Divine Nature, it is very difficult, if notabsolutely impossible , to deduce merely from contemplating the works of nature; nor will the uniformity alone of the plan, evenwere it allowed, give us any assurance of that attribute. Whereas the argument a priori......
You seem to reason, DEMEA, interposed CLEANTHES, as if those advantages andconveniencies in the abstract argument were full proofs of its solidity.But it is first proper, in my opinion, to determine what argument of this nature youchuse to insist on; and we shall afterwards, from itself, better than from its useful consequences,endeavour to determine what value we ought to put upon it.
The argument, replied DEMEA, whichI would insist on is the common one. Whatever exists must have a cause or reason of its existence; it beingabsolutely impossible forany thing thing to produce itself, or be the cause of its own existence. In mounting up, therefore, from effects to causes, wemust either go on in tracing an infinite succession, without any ultimate cause at all, or must at last have recourse to some ultimate cause, that is necessarily existent: Now that the first supposition is absurd may be thus proved.In the infinite chain or succession of causes and effects, each single effect is determined to exist by the power and efficacy of that cause, which immediately preceded; but the whole eternal chain or succession, taken together, is not determined or caused by any thing: and yet it is evident that it requires a cause or reason, as much as any particular object, which begins to exist in time. The question is still reasonable,Why this particular succession of causes existed from eternity, and not any other succession, or no succession at all. If there be no necessarily-existent being, any supposition, which can be formed, is equally possible; nor is there any more absurdity in Nothing's having existed from eternity, than there is in that succession of causes, which constitutes the universe. What was it then, which determined something to exist rather than nothing, and bestowed being on a particular possibility, exclusive of the rest? External causes, there are supposed to be none. Chance is a word without a meaning. Was itNothing ?But that can never produceany thing . We must, therefore, have recourse to anecessarily-existent Being, who carries the REASON of his existence in himself; and who cannot be supposed not to exist without an express contradiction. There is consequently such a Being, that is, there is a Deity.
I shall not leave it to PHILO, said CLEANTHES, (though I know that the starting objections is his chief delight) to point out the weakness of this metaphysical reasoning. It seems to me so obviouslyill-grounded , and at the same time of so little consequence to the cause of true piety and religion, that I shall myself venture to show the fallacy of it.
I shall begin with observing, that there is an evident absurdity in pretending to demonstrate a matter of fact, or to prove it by any arguments a priori. Nothing is demonstrable, unless the contrary implies a contradiction. Nothing, that is distinctly conceivable, implies a contradiction. Whatever we conceive as existent, we can also conceive as non-existent. There is nobeing, therefore, whose non-existence implies a contradiction.Consequently there is no being, whose existence is demonstrable.I propose this argument as entirely decisive, and am willing to rest the whole controversy upon it.
It is pretended that the Deity is a necessarily-existent existent being; and this necessity of his existence is attempted to be explained by asserting, that, if we knew his whole essence or nature, we should perceive it to be as impossible for him not to exist as for twice two not to be four.But it is evident, that this can never happen, while our faculties remain the same as at present. It will still be possible for us, at any time, to conceive the non-existence of what we formerly conceived to exist; nor can the mind ever lie under a necessity of supposing any object to remain always in being; in the same manner as we lie under a necessity of always conceiving twice two to be four. The words, therefore, necessary existence, have no meaning; or, which is the same thing, none that is consistent.
But farther; why may not the material universe be the necessarily-existent Being, according to this pretended explication of necessity? We dare not affirm that we know all the qualities of matter; and for aught we can determine, it may contain some qualities, which, were they known, would make its non-existence appear as great a contradiction as that twice two is five. I find only one argument employed to prove, that the material world is not thenecessarily-existent Being; and this argument is derived from the contingency both of the matter and the form of the world.
Any particle of matter,
'tis said*
may be conceived to be annihilated; and any form may be conceived to be altered. Such an annihilation or alteration, therefore, is not impossible.
But it seems a great partiality not to perceive, that the same argument extends equally to the Deity, so far as we have any conception of him; and that the mind can at least imagine him to be non-existent, or his attributes to be altered. It must be some unknown, inconceivable qualities, which can make his nonexistence appear impossible, or his attributes unalterable: And no reasoncan be assigned , why these qualities may not belong to matter. As they are altogether unknown and inconceivable, theycan never be proved incompatible with it.
Add to this, that in tracing an eternal succession of objects, it seems absurd to enquire for a general cause or first author. How can anything, that exists from eternity, have a cause; since that relation implies a priority in time and a beginning of existence?
In such a chain too, or succession of objects, each part is caused by that which preceded it, and causes that which succeeds it. Where then is the difficulty?But the WHOLE, you say, wants a cause.I answer, that the uniting of these parts into a whole, like the uniting of several distinct counties into one kingdom, or several distinct members into one body, is performed merely by an arbitrary act of the mind, and has no influence on the nature of things. Did I show you the particular causes of each individual in a collection of twenty particles of matter, I should think it very unreasonable, should you afterwards ask me, whatwas the cause of the whole twenty . Thatis sufficiently explained in explaining the cause of the parts.
Though thereasonings , which you have urged, CLEANTHES, may well excuseme , said PHILO, from starting any farther difficulties; yet I cannot forbear insisting still upon another topic.'Tis observed by arithmeticians, that the products of 9 compose always either 9 or some lesser product of 9; if you add together all the characters, of which any of the former products is composed. Thus, of 18, 27, 36, which are products of9 , you make 9 by adding 1 to 8, 2 to 7, 3 to 6. Thus 369 is a product also of9 ; and if you add 3, 6, and 9, you make 18, a lesser product of 9*. To a superficial observer, so wonderful a regularity may be admired as the effect either of chance or design; but a skilful algebraist immediately concludes it to be the work of necessity, and demonstrates, that it must for ever result from the nature of these numbers. Is it not probable, I ask, that the wholeoeconomy of the universeis conducted by a like necessity, though no human algebra can furnish a key, which solves the difficulty?And instead of admiring the order of natural beings, may it not happen, that, could we penetrate into the intimate nature of bodies, we should clearly see why it was absolutely impossible, they could ever admit of any other disposition? So dangerous is it to introduce this idea of necessity into the present question!and so naturally does it afford an inference directly opposite to the religious hypothesis!
But dropping all these abstractions, continued PHILO; and confining ourselves to more familiar topics; I shall venture to add an observation, that the argument a priori has seldom been found very convincing, except to people of a metaphysical head, who have accustomed themselves to abstract reasoning, and who finding from mathematics, that the understanding frequently leads to truth, through obscurity, and contrary to first appearances, have transferred the same habit of thinking to subjects, where it ought not to have place. Other people, even of good sense and the best inclined to religion, feel always some deficiency in such arguments, though they are not perhaps able to explain distinctly where it lies. A certain proof, that men ever did, and ever will derive their religion from other sources than from this species of reasoning.
