The supporters of evolution base their arguments upon the remarkable resemblance between the brain of man and that of certain other animals. Now, I admit this striking analogy; I admit that every chief fissure and fold in the brain of man has its counterpart in that of the gorilla and the ourang-outang; and I am not prepared to deny the statement, that as far as the organ of intelligence is concerned, there is no very striking physical difference between him who weighs the stars and makes the light tell its secrets as to the constitution of distant worlds, and the howling senseless brute, who lives merely to satisfy his animal appetites. All animals of the vertebrate type are constructed on a plan which is essentially similar, not only as regards their skeleton, but as regards their brain. I don't deny that man is an animal, and that he has the essential properties of a highly organised one; but what I do maintain is, that the brain, after all, is merely an _instrument_ by which the high psychological attributes peculiar to man become _externally_ manifested.[37] Thought is not phosphorus, as some would have us believe; the human mind is not the result of a mere molecular arrangement of cerebral matter. There is something over and above all this, and the very resemblance of man's physical nature to that of some members of the brute creation, proves beyond all doubt that his superiority to them is hyperphysical, and I fully endorse Mr. Froude's philosophical remarks, when he says, "It is nothing to me how the Maker of me has been pleased to construct the organised substance which I call my body. It is mine, but it is not I. The νους, the intellectual spirit, being an ουσια--an essence--I believe to be an imperishable something which has been engendered in me from another source." The unhappy idiot, that stricken member of our race, possesses the tripartite nature of man--for he has not only the σωμα or material part, and the ψυχη or principle of animal life, but he also undoubtedly possesses the πνευμα or principle of immortal life.
