At least, you may safely infer, said Philo, that the foregoing hypothesis is so far incomplete and imperfect, which I 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 into Anthropomorphism, the better to preserve a conformity to common experience. Let us once more put into trial. In all instances 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 all instances 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 immediately any thing but the members of its own body; and indeed, the equality of action and re-action seems to be an 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 animal ingenerable 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 disputant triumphs 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 the Sceptic; 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 of judgment is here our only reasonable resource. And if every attack, as is commonly observed, and no defence, 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 to defend?

[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 not absolutely impossible, to deduce merely from contemplating the works of nature; nor will the uniformity alone of the plan, even were 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 and conveniences 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 you choose 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, which I would insist on, is the common one. Whatever exists must have a cause or reason of its existence; it being absolutely impossible for any thing to produce itself, or be the cause of its own existence. In mounting up, therefore, from effects to causes, we must 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 it Nothing? But that can never produce any thing. We must, therefore, have recourse to a necessarily 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 obviously ill-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.
