in nature, and moreover constitutes the basis of our conception of all causation, therefore all causation is probably volitional in character. But as this is a favourite argument with some theists, I shall introduce another quotation from Mr. Mill, which is taken from a different work.

"Volitions are not known to produce anything directly except nervous action, for the will influences even the muscles only through the nerves. Though it were granted, then, that every phenomenon has an efficient and not merely a phenomenal cause, and that volition, in the case of the particular phenomena which are known to be produced by it, is that cause; are we therefore to say with these writers that since we know of no other efficient cause, and ought not to assume one without evidence, there is no other, and volition is the direct cause of all phenomena? A more outrageous stretch of inference could hardly be made. Because among the infinite variety of the phenomena of nature there is one, namely, a particular mode of action of certain nerves which has for its cause and, as we are now supposing, for its efficient cause, a state of our mind; and because this is the only efficient cause of "which we are conscious, being the only one of which, in the nature of the case, we can be conscious, since it is the only one which exists within ourselves; does this justify us in concluding that all other phenomena must have the same kind of efficient cause with that one eminently special, narrow, and peculiarly human or animal phenomenon?" It is then shown that a logical parallel to this mode of inference is that of generalising from the one known instance of the earth being inhabited, to the conclusion that "every heavenly body without exception, sun, planet, satellite, comet, fixed star, or nebula, is inhabited, and must be so from the inherent constitution of things." After which the passage continues, "It is true there are cases in which, with acknowledged propriety, we generalise from a single instance to a multitude of instances. But they must be instances which resemble the one known instance, and not such as have no circumstance in common with it except that of being instances.... But the supporters of the volition theory ask us to infer that volition causes everything, for no other reason except that it causes one particular thing; although that one phenomenon, far from being a type of all natural phenomena, is eminently peculiar; its laws bearing scarcely any resemblance to those of any other phenomenon, whether of inorganic or of organic nature."^[3]

CHAPTER II.

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
