THE ARGUMENT FROM THE EXISTENCE OF THE HUMAN MIND.

      § 8. Leaving now the obviously untenable arguments, we next come to those which, in my opinion, may properly be termed scientific.

      It will be convenient to classify those as three in number; and under one or other of these heads nearly all the more intelligent advocates of Theism will be found to range themselves.

§ 9. We have first the argument drawn from the existence of the human mind. This is an argument which, for at least the last three centuries, and especially during the present one, has been more relied upon than any other by philosophical thinkers. It consists in the reflection that the being of our own subjective intelligence is the most certain fact which our experience supplies, that this fact demands an adequate cause for its explanation, and that the only adequate cause of our intelligence must be some other intelligence. Granting the existence of a conditioned intelligence (and no one could reasonably suppose his own intelligence to be otherwise), and the existence of an unconditioned intelligence becomes a logical necessity, unless we deny either the validity of the principle that every effect must have an adequate cause, or else that the only adequate cause of Mind is Mind.

      It has been a great satisfaction to me to find that my examination of this argument—an examination which was undertaken and completed several months before Mr. Mill's essay appeared—has been minutely corroborated by that of our great logician. I mention this circumstance here, as on previous occasions, not for the petty motive of vindicating my own originality, but because in matters of this kind the accuracy of the reasoning employed, and therefore the logical validity of the conclusions attained, are guaranteed in the best possible manner, if the trains of thought have been independently pursued by different minds.

§ 10. Seeing that, among the advocates of this argument, Locke went so far as to maintain that by it alone he could render the existence of a Deity as certain as any mathematical demonstration, it is only fair, preparatory to our examining this argument, to present it in the words of this great thinker.

      He says:—"There was a time when there was no knowing (i.e., conscious) being, and when knowledge began to be; or else there has been also a knowing being from all eternity. If it be said, there was a time when no being had any knowledge, when that eternal being was void of all understanding, I reply, that then it was impossible there should ever have been any knowledge: it being as impossible that things wholly void of knowledge, and operating blindly, and without perception, should produce a knowing being, as it is impossible that a triangle should make itself three angles bigger than two right ones. For 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."^[4]

      Now, although this argument has been more fully elaborated by other writers, the above presentation contains its whole essence. It will be seen that it has the great advantage of resting immediately upon the foundation from which all argument concerning this or any other matter, must necessarily arise, viz.—upon the very existence of our argumentative faculty itself. For the sake of a critical examination, it is desirable to throw the argument before us into the syllogistic form. It will then stand thus:—

      All known minds are caused by an unknown mind. Our mind is a known mind; therefore, our mind is caused by an unknown mind.

§ 11. Now the major premiss of this syllogism is inadmissible for two reasons: in the first place, it is assumed that known mind can only be caused by unknown mind; and, in the second place, even if this assumption were granted, it would not explain the existence of Mind as Mind. To take the last of these objections first, in the words of Mr. Mill, "If the mere existence of Mind is supposed to require, as a necessary antecedent, another Mind greater and more powerful, the difficulty is not removed by going one step back: the creating mind stands as much in need of another mind to be the source of its existence as the created mind. Be it remembered that we have no direct knowledge (at least apart from Revelation) of a mind which is even apparently eternal, as Force and Matter are: an eternal mind is, as far as the present argument is concerned, a simple hypothesis to account for the minds which we know to exist. Now it is essential to an hypothesis that, if admitted, it should at least remove the difficulty and account for the facts. But it does not account for mind to refer our mind to a prior mind for its origin. The problem remains unsolved, nay, rather increased."

      Nevertheless, I think that it is open to a Theist to answer, "My object is not to explain the existence of Mind in the abstract, any more than it is my object to explain Existence itself in the abstract—to either of which absurd attempts Mr. Mill's reasoning would be equally applicable;—but I seek for an explanation of my own individual finite mind, which I know to have had a beginning in time, and which, therefore, in accordance with the widest and most complete analogy that experience supplies, I believe to have been caused. And if there is no other objection to my believing in Intelligence as the cause of my intelligence, than that I cannot prove my own intelligence caused, then I am satisfied to let the matter rest here; for as every argument must have some basis of assumption to stand upon, I am well pleased to find that the basis in this case is the most solid which experience can supply, viz.—the law of causation. Fully admitting that it does not account for Mind (in the abstract) to refer one mind to a prior mind for its origin; yet my hypothesis, if admitted, does account for the fact that my mind exists; and this is all that my hypothesis is intended to cover. For to endeavour to explain the existence of an eternal mind, could only be done by those who do not understand the meaning of these words."

      Now, I think that this reply to Mr. Mill, on the part of a theist, would so far be legitimate; the theistic hypothesis does supply a provisional explanation of the existence of known minds, and it is, therefore, an explanation which, in lieu of a better, a theist may be allowed to retain. But a theist may not be allowed to confuse this provisional explanation of his own mind's existence with that of the existence of Mind in the abstract; he must not be allowed to suppose that, by thus hypothetically explaining the existence of known minds, he is thereby establishing a probability in favour of that hypothetical cause, an Unknown Mind. Only if he has some independent reason to infer that such an Unknown Mind exists, could such a probability be made out, and his hypothetical explanation of known mind become of more value than a guess. In other words, although the theistic hypothesis supplies a possible explanation of known mind, we have no reason to conclude that it is the true explanation, unless other reasons can be shown to justify, on independent grounds, the validity of the theistic hypothesis. Hence it is manifestly absurd to adduce this explanation as evidence of the hypothesis on which it rests—to argue that Theism must therefore be true; because we assume it to be so, in order to explain known mind, as distinguished from Mind. If it be answered, We are justified in assuming Theism true, because we are justified in assuming that known mind can only have been caused by an unknown mind, and hence that Mind must somewhere be self-existing, then this is to lead us to the second objection to the above syllogism.

§ 12. And this second objection is of a most serious nature. "Mind can only be caused by Mind," and, therefore, Mind must either be uncaused, or caused by a Mind. What is our warrant for ranking this assertion? Where is the proof that nothing can have caused a mind except another mind? Answer to this question there is none. For aught that we can ever know to the contrary, anything within the whole range of the Possible may be competent to produce a self-conscious intelligence—and to assume that Mind is so far an entity sui generis, that it must either be self-existing, or derived from another mind which is self-existing, is merely to beg the whole
