Theism—we have seen two important objections to lie.

'For, in the first place, the sense in which the word "inconceivable" is here used is that of the impossibility of framing realizable relations in the thought; not that of the impossibility of framing abstract relations in thought. In the same sense, though in a lower degree, it is true that the complexity of the human organization and its functions is inconceivable; but in this sense the word "inconceivable" has much less weight in an argument than it has in its true sense. And, without waiting again to dispute (as we did in the case of the speculative standing of Materialism) how far even the genuine test of inconceivability ought to be allowed to make against an inference which there is a body of scientific evidence to substantiate, we went on to the second objection against this fundamental position of metaphysical teleology. This objection, it will be remembered, was, that it is as impossible to conceive of cosmic harmony as an effect of Mind [i.e. Mind being what we know it in experience to be], as it is to conceive of it as an effect of mindless evolution. The argument from inconceivability, therefore, admits of being turned with quite as terrible an effect on Theism, as it can possibly be made to exert on Atheism.

'Hence this more refined form of teleology which we are considering, and which we saw to be the last of the possible arguments in favour of Theism, is met on its own ground by a very crushing opposition: by its metaphysical character it has escaped the opposition of physical science, only to encounter a new opposition in the region of pure psychology to which it fled. As a conclusion to our whole inquiry, therefore, it devolved on us to determine the relative magnitudes of these opposing forces. And in doing this we first observed that, if the supporters of metaphysical teleology objected à priori to the method whereby the genesis of natural law was deduced from the datum of the persistence of force, in that this method involved an unrestricted use of illegitimate symbolic conceptions; then it is no less open to an atheist to object à priori to the method whereby a directing Mind was inferred from the datum of cosmic harmony, in that this method involved the postulation of an unknowable cause,—and this of a character which the whole history of human thought has proved the human mind to exhibit an overweening tendency to postulate as the cause of natural phenomena. On these grounds, therefore, I concluded that, so far as their respective standing à priori is concerned, both theories may be regarded as about equally suspicious. And similarly with regard to their standing à posteriori; for as both theories require to embody at least one infinite term, they must each alike be pronounced absolutely inconceivable. But, finally, if the question were put to me which of the two theories I regarded as the more rational, I observed that this is a question which no one man can answer for another. For as the test of absolute inconceivability is equally destructive of both theories, if a man wishes to choose between them, his choice can only be determined by what I have designated relative inconceivability—i.e. in accordance with the verdict given by his individual sense of probability as determined by his previous habit of thought. And forasmuch as the test of relative inconceivability may be held in this matter legitimately to vary with the character of the mind which applies it, the strictly rational probability of the question to which it is applied varies in like manner. Or otherwise presented, the only alternative for any man in this matter is either to discipline himself into an attitude of pure scepticism, and thus to refuse in thought to entertain either a probability or an improbability concerning the existence of a God; or else to incline in thought towards an affirmation or a negation of God, according as his previous habits of thought have rendered such an inclination more facile in the one direction than in the other. And although, under such circumstances, I should consider that man the more rational who carefully suspended his judgement, I conclude that if this course is departed from, neither the metaphysical teleologist nor the scientific atheist has any perceptible advantage over the other in respect of rationality. For as the formal conditions of a metaphysical teleology are undoubtedly present on the one hand, and the formal conditions of a speculative atheism are as undoubtedly present on the other, there is thus in both cases a logical vacuum supplied wherein the pendulum of thought is free to swing in whichever direction it may be made to swing by the momentum of preconceived ideas.

'§ 6. Such is the outcome of our investigation, and considering the abstract nature of the subject, the immense divergence of opinion which at the present time is manifested with regard to it, as well as the confusing amount of good, bad and indifferent literature on both sides of the controversy which is extant;—considering these things, I do not think that the result of our inquiry can be justly complained of on the score of its lacking precision. At a time like the present, when traditional beliefs respecting Theism are so generally accepted, and so commonly concluded as a matter of course to have a large and valid basis of induction whereon to rest, I cannot but feel that a perusal of this short essay, by showing how very concise the scientific status of the subject really is, will do more to settle the minds of most readers as to the exact standing at the present time of all the probabilities of the question, than could a perusal of all the rest of the literature upon this subject. And, looking to the present condition of speculative philosophy, I regard it as of the utmost importance to have clearly shown that the advance of science has now entitled us to assert, without the least hesitation, that the hypothesis of Mind in nature is as certainly superfluous to account for any of the phenomena of nature, as the scientific doctrine of the persistence of force and the indestructibility of matter is certainly true.

'On the other hand, if any one is inclined to complain that the logical aspect of the question has not proved itself so unequivocally definite as has the scientific, I must ask him to consider that, in any matter which does not admit of actual demonstration, some margin must of necessity be left for variations of individual opinion. And, if he bears this consideration in mind, I feel sure that he cannot properly complain of my not having done my utmost in this case to define as sharply as possible the character and the limits of this margin.

'§ 7. And now, in conclusion, I feel it is desirable to state that any antecedent bias with regard to Theism which I individually possess is unquestionably on the side of traditional beliefs. It is therefore with the utmost sorrow that I find myself compelled to accept the conclusions here worked out; and nothing would have induced me to publish them, save the strength of my conviction that it is the duty of every member of society to give his fellows the benefit of his labours for whatever they may be worth. Just as I am confident that truth must in the end be the most profitable for the race, so I am persuaded that every individual endeavour to attain it, provided only that such endeavour is unbiassed and sincere, ought without hesitation to be made the common property of all men, no matter in what direction the results of its promulgation may appear to tend. And so far as the ruination of individual happiness is concerned, no one can have a more lively perception than myself of the possibly disastrous tendency of my work. So far as I am individually concerned, the result of this analysis has been to show that, whether I regard the problem of Theism on the lower plane of strictly relative probability, or on the higher plane of purely formal considerations, it equally becomes my obvious duty to stifle all belief of the kind which I
