of a God. In other words, if we can prove that the order of existence to which Mind belongs, is so essentially different from that order, or those orders, to which all else belongs, as to render it abstractedly impossible that the latter can produce the former—if we can prove this, we have likewise proved the existence of a Deity. But this is just the point in dispute, and to set out with a bare affirmation of it is merely to beg the question and to abandon the discussion. Doubtless, by the mere act of consulting their own consciousness, the fact now in dispute appears to some persons self-evident. But in matters of such high abstraction as this, even the evidence of self-evidence must not be relied upon too implicitly. To the country boor it appears self-evident that wood is annihilated by combustion; and even to the mind of the greatest philosophers of antiquity it seemed impossible to doubt that the sun moved over a stationary earth. Much more, therefore, may our broad distinction between "cogitative and incogitative being"[5] not be a distinction which is "legitimated by the conditions of external reality."
Doubtless many will fall back upon the position already indicated, "It is as repugnant to the idea of senseless matter, that it should put into itself sense, perception, and knowledge, as it is repugnant to the idea of a triangle, that it should put into itself greater angles than two right ones." But, granting this, and also that conscious matter is the sole alternative, and what follows? Not surely that matter cannot perceive, and feel, and know, merely because it is repugnant to our idea of it that it should. Granting that there is no other alternative in the whole possibility of things, than that matter must be conscious, or that self-conscious Mind must somewhere be self-existing; and granting that it is quite "impossible for us to conceive" of consciousness as an attribute of matter; still surely it would be a prodigious leap to conclude that for this reason matter cannot possess this attribute. Indeed, Locke himself elsewhere strangely enough insists that thought may be a property of matter, if only the Deity chose to unite that attribute with that substance. Why it should be deemed abstractedly impossible for matter to think if there is no God, and yet abstractedly possible that it should think if there is a God, I confess myself quite unable to determine; but I conceive that it is very important clearly to point out this peculiarity in Locke's views, for he is a favourite authority with theists, and this peculiarity amounts to nothing less than a suicide of his entire argument. The mere circumstance that he assumed the Deity capable of endowing matter with the faculty of thinking, could not have enabled him to conceive of matter as thinking, any more than he could conceive of this in the absence of his assumption. Yet in the one case he recognises the possibility of matter thinking, and in the other case denies such possibility, and this on the sole ground of its being inconceivable! However, I am not here concerned with Locke's eccentricities:[6] I am merely engaged with the general principle, that a subjective inability to establish certain relations in thought is no sufficient warrant for concluding that corresponding objective relations may not obtain.
§ 13. Hence, an objector to the above syllogism need not be a materialist; it is not even necessary that he should hold any theory of things at all. Nevertheless, for the sake of definition, I shall assume that he is a materialist. As a materialist, then, he would appear to be as much entitled to his hypothesis as a theist is to his—in respect, I mean, of this particular argument. For although I think, as before shown, that in strict reasoning a theist might have taken exception to the last-quoted passage from Mill in its connection with the law of causation, that passage, if considered in the present connection, is certainly unanswerable. What is the state of the present argument as between a materialist and a theist? The mystery of existence and the inconceivability of matter thinking are their common data. Upon these data the materialist, justly arguing that he has no right to make his own conceptive faculty the unconditional test of objective possibility, is content to merge the mystery of his own mind's existence into that of Existence in general; while the theist, compelled to accept without explanation the mystery of Existence in general, nevertheless has recourse to inventing a wholly gratuitous hypothesis to explain one mode of existence in particular. If it is said that the latter hypothesis has the merit of causing the mystery of material existence and the mystery of mental existence to be united in a thinkable manner—viz., in a self-existing Mind—I reply, It is not so; for in whatever degree it is unthinkable that Matter should be the cause of Mind, in that precise degree must it be unthinkable that Mind was ever the cause of Matter, the correlatives being in each case the same, and experience affording no evidence of causality in either.
§ 14. The two hypotheses, therefore, are of exactly equivalent value, save that while the one has a certain basis of fact to rest upon,[7] the other is wholly arbitrary. But it may still be retorted, 'Is not that which is most conceivable most likely to be true? and if it is more conceivable that my intelligence is caused by another Intelligence than that it is caused by Non-intelligence, may I not regard the more conceivable hypothesis as also the more probable one? It is somewhat difficult to say how far this argument is, in this case, valid; only I think it is quite evident that its validity is open to grave dispute. For nothing can be more evident to a philosophical thinker than that the substance of Mind must—so far at least as we can at present see—necessarily be unknowable; so that if Matter (and Force) be this substance, we should antecedently expect to find that the actual causal connection should, in this particular case, be more inconceivable than some imaginary one: it would be more natural for the mind to infer that something conceivably more akin to itself should be its cause, than that this cause should be the entity which really gives rise to the unthinkable connection. But even waiving this reflection, and granting that the above argument is valid, it is still to an indefinite degree valueless, seeing that we are unable to tell how much it is more likely that the more conceivable should here be true than that the less conceivable should be so.
§ 15. Returning then to Locke's comparison between the certainty of this argument and that which proves the sum of the angles of a triangle to be equal to two right-angles, I should say that there is a virtual, though not a formal, fallacy in his presentation. For mathematical science being confessedly but of relative significance, any comparison between the degree of certainty attained by reasoning upon so transcendental a subject as the present, and that of mathematical demonstrations regarding relative truth, must be misleading. In the present instance, the whole strain of the argument comes upon the adequacy of the proposed test of truth, viz., our being able to conceive it if true. Now, will any one undertake to say that this test of truth is of equivalent value when it is applied to a triangle and when it is applied to the Deity. In the one case we are dealing with a geometrical figure of an exceedingly simple type, with which our experience is well acquainted, and presenting a very limited number of relations for us to contemplate. In the other case we are endeavouring to deal with the summum genus of all mystery, with reference to which experience is quite impossible, and which in its mention contains all the relations that are to us unknown and unknowable. Here, then, is the oversight. Because men find conceivability a valid test of truth in the affairs of everyday life—as it is easy to show à priori that it must be, if our experience has been formed under a given code of constant and general laws—therefore they conclude that it must be equally valid wherever it is applied; forgetting that its validity must perforce decrease in proportion to the distance at which the test is applied from the sphere of experience.[8]
§ 16. Upon the whole, then, I think it is transparently obvious that the mere fact of our being unable to conceive, say, how any disposition of matter and motion could possibly give rise to a self-conscious intelligence, in no wise warrants us in concluding that for this reason no such disposition is possible. The only question would appear to be, whether the test which is here proposed as an unconditional criterion of truth should be allowed any the smallest degree of credit. Seeing, on the one hand, how very fallible the test in question is known to have proved itself in many cases of much less speculative difficulty—seeing, too, that even now "the philosophy of the condition proves that things there are which may, nay must, be true, of which nevertheless the mind is unable to construe to itself the possibility;"[9] and seeing, on the other hand, that the substance of Mind, whatever it is, must necessarily be unknowable;—seeing these things, if any question remains as to whether the test of inconceivability should in this case be regarded as having any degree of validity at all, there can, I think, be no reasonable doubt that such degree
