That famous defence of theology against the a priori scepticism of Freethinkers of the eighteenth century, who based their arguments on the inconsistency of the revealed scheme of salvation with the attributes of the Deity, consists, essentially, in conclusively proving that, from a moral point of view, Nature is at least as reprehensible as orthodoxy. If you tell me, says Butler, in effect, that any part of revealed religion must be false because it is inconsistent with the divine attributes of justice and mercy; I beg leave to point out to you, that there are undeniable natural facts which are fully open to the same objection. Since you admit that nature is the work of God, you are forced to allow that such facts are consistent with his attributes. Therefore, you must also admit, that the parallel facts in the scheme of orthodoxy are also consistent with them, and all your arguments to the contrary fall to the ground. Q.E.D. In fact, the solid sense of Butler left the Deism of the Freethinkers not a leg to stand upon. Perhaps, however, he did not remember the wise saying that "A man seemeth right in his own cause, but another cometh after and judgeth him." Hume's Epicurean philosopher adopts the main arguments of the Analogy, but unfortunately drives them home to a conclusion of which the good Bishop would hardly have approved.

"I deny a Providence, you say, and supreme governor of the world, who guides the course of events, and punishes the vicious with infamy and disappointment, and rewards the virtuous with honour and success in all their undertakings. But surely I deny not the course itself of events, which lies open to every one's inquiry and examination. I acknowledge that, in the present order of things, virtue is attended with more peace of mind than vice, and meets with a more favourable reception from the world. I am sensible that, according to the past experience of mankind, friendship is the chief joy of human life, and moderation the only source of tranquillity and happiness. I never balance between the virtuous and the vicious course of life; but am sensible that, to a well-disposed mind, every advantage is on the side of the former. And what can you say more, allowing all your suppositions and reasonings? You tell me, indeed, that this disposition of things proceeds from intelligence and design. But, whatever it proceeds from, the disposition itself, on which depends our happiness and misery, and consequently our conduct and deportment in life, is still the same. It is still open for me, as well as you, to regulate my behaviour by my experience of past events. And if you affirm that, while a divine providence is allowed, and a supreme distributive justice in the universe, I ought to expect some more particular reward of the good, and punishment of the bad, beyond the ordinary course of events, I here find the same fallacy which I have before endeavoured to detect. You persist in imagining, that if we grant that divine existence for which you so earnestly contend, you may safely infer consequences from it, and add something to the experienced order of nature, by arguing from the attributes which you ascribe to your gods. You seem not to remember that all your reasonings on this subject can only be drawn from effects to causes; and that every argument, deduced from causes to effects, must of necessity be a gross sophism, since it is impossible for you to know anything of the cause, but what you have antecedently not inferred, but discovered to the full, in the effect.

"But what must a philosopher think of those vain reasoners who, instead of regarding the present scene of things as the sole object of their contemplation, so far reverse the whole course of nature, as to render this life merely a passage to something further; a porch, which leads to a greater and vastly different building; a prologue which serves only to introduce the piece, and give it more grace and propriety? Whence, do you think, can such philosophers derive their idea of the gods? From their own conceit and imagination surely. For if they derive it from the present phenomena, it would never point to anything further, but must be exactly adjusted to them. That the divinity may possibly be endowed with attributes which we have never seen exerted; may be governed by principles of action which we cannot discover to be satisfied; all this will freely be allowed. But still this is mere possibility and hypothesis. We never can have reason to infer any attributes or any principles of action in him, but so far as we know them to have been exerted and satisfied.

"Are there any marks of a distributive justice in the world? If you answer in the affirmative, I conclude that, since justice here exerts itself, it is satisfied. If you reply in the negative, I conclude that you have then no reason to ascribe justice, in our sense of it, to the gods. If you hold a medium between affirmation and negation, by saying that the justice of the gods at present exerts itself in part, but not in its full extent, I answer that you have no reason to give it any particular extent, but only so far as you see it, at present, exert itself."—(IV. pp. 164-6.)

Thus, the Freethinkers said, the attributes of the Deity being what they are, the scheme of orthodoxy is inconsistent with them; whereupon Butler gave the crushing reply: Agreeing with you as to the attributes of the Deity, nature, by its existence, proves that the things to which you object are quite consistent with them. To whom enters Hume's Epicurean with the remark: Then, as nature is our only measure of the attributes of the Deity in their practical manifestation, what warranty is there for supposing that such measure is anywhere transcended? That the "other side" of nature, if there be one, is governed on different principles from this side?

Truly on this topic silence is golden; while speech reaches not even the dignity of sounding brass or tinkling cymbal, and is but the weary clatter of an endless logomachy. One can but suspect that Hume also had reached this conviction; and that his shadowy and inconsistent theism was the expression of his desire to rest in a state of mind, which distinctly excluded negation, while it included as little as possible of affirmation, respecting a problem which he felt to be hopelessly insoluble.

But, whatever might be the views of the philosopher as to the arguments for theism, the historian could have no doubt respecting its many-shaped existence, and the great part which it has played in the world. Here, then, was a body of natural facts to be investigated scientifically, and the result of Hume's inquiries is embodied in the remarkable essay on the Natural History of Religion. Hume anticipated the results of modern investigation in declaring fetishism and polytheism to be the form in which savage and ignorant men naturally clothe their ideas of the unknown influences which govern their destiny; and they are polytheists rather than monotheists because,—

" ... the first ideas of religion arose, not from a contemplation of the works of nature, but from a concern with regard to the events of life, and from the incessant hopes and fears which actuate the human mind ... in order to carry men's attention beyond the present course of things, or lead them into any inference concerning invisible intelligent power, they must be actuated by some passion which prompts their thought and reflection, some motive which urges their first inquiry. But what passion shall we have recourse to, for explaining an effect of such mighty consequence? Not speculative curiosity merely, or the pure love of truth. That motive is too refined for such gross apprehensions, and would lead men into inquiries concerning the frame of nature, a subject too large and comprehensive for their narrow capacities. No passions, therefore, can be supposed to work on such barbarians, but the ordinary affections of human life; the anxious concern for happiness, the dread of future misery, the terror of death, the thirst of revenge, the appetite for food and other necessaries. Agitated by hopes and fears of this nature, especially the latter, men scrutinize, with a trembling curiosity, the course of future causes, and examine the various and contrary events of human life. And in this disordered scene, with eyes still more disordered and astonished, they see the first obscure traces of divinity."—(IV. pp. 443, 4.)

The shape assumed by these first traces of divinity is that of the shadows of men's own minds, projected out of themselves by their imaginations:—

"There is an universal tendency among mankind to conceive all beings like themselves, and to transfer to every object those qualities with which they are familiarly acquainted, and of which they are intimately conscious.... The unknown causes which continually employ their thought, appearing always in the same aspect, are all apprehended to be of the same kind or species. Nor is it long before we ascribe to them thought, and reason, and passion, and sometimes even the limbs and figures of men, in order to bring them nearer to a resemblance with ourselves."—(IV. pp. 446-7.)

Hume asks whether polytheism really deserves the name of theism.

"Our ancestors in Europe, before the revival of letters, believed as we do at present, that there was one supreme God, the author of nature, whose power, though in itself uncontrollable, was yet often exerted by the interposition of his angels and subordinate ministers, who executed his sacred purposes. But they also believed, that all nature was full of other invisible powers: fairies, goblins, elves, sprights; beings stronger and mightier than men, but much inferior to the celestial natures who surround the throne of God. Now, suppose that any one, in these ages, had denied the existence of God and of his angels, would not his impiety justly have deserved the appellation of atheism, even though he had still allowed, by some odd capricious reasoning, that the popular stories of elves and fairies were just and well grounded? The difference, on the one hand, between such a person and a genuine theist, is infinitely greater than that, on the other, between him and one that absolutely excludes all invisible intelligent power. And it is a fallacy, merely from the casual resemblance of names, without any conformity of meaning, to rank such opposite opinions under the same denomination.

"To any one who considers justly of the matter, it will appear that the gods of the polytheists are no better than the elves and fairies of our ancestors, and merit as little as any pious worship and veneration. These pretended religionists are really a kind of superstitious atheists, and acknowledge no being that corresponds to our idea of a Deity. No first principle of mind or thought; no supreme government and administration; no divine contrivance or intention in the fabric of the world."—(IV. pp. 450-51.)
