Pereira and Descartes maintained that the universe was mistaken, that God was a juggler, that He had given animals all the instruments of life and sensation, so that they might have neither life nor sensation, properly speaking. But I do not know what so-called philosophers, in order to answer Descartes' chimera, leaped into the opposite chimera; they gave liberally of pure spirit to the toads and the insects. Between these two madnesses, the one refusing feeling to the organs of feeling, the other lodging a pure spirit in a bug, somebody thought of a middle path. It was instinct. And what is instinct? Oh, oh, it is a substantial form; it is a plastic form; it is I do not know what! it is instinct. I shall be of your opinion so long as you will call the majority of things, "I do not know what"; so long as your philosophy begins and ends with "I do not know what", I shall quote Prior to you in his poem on the vanity of the world. The author of the article SOUL in the "Encyclopedia" explains himself like this:--"I picture the animals' soul as an immaterial and intelligent substance, but of what species? It must, it seems to me, be an active principle which has sensations, and which has only that.... If we reflect on the nature of the soul of animals, it supplies us with groundwork which might lead us to think that its spirituality will save it from annihilation." I do not know how one pictures an immaterial substance. To picture something is to make an image of it; and up till now nobody has been able to paint the spirit. For the word "picture", I want the author to understand "I conceive"; speaking for myself, I confess I do not conceive it. I confess still less that a spiritual soul may be annihilated, because I do not conceive either creation or non-existence; because I have never been present at God's council; because I know nothing at all about the principle of things. If I wish to prove that the soul is a real being, someone stops me by telling me that it is a faculty. If I assert that it is a faculty, and that I have the faculty of thinking, I am told that I am mistaken; that God, the eternal master of all nature, does everything in me, and directs all my actions and all my thoughts; that if I produced my thoughts, I should know the thought I will have in a minute; that I never know it; that I am only an automaton with sensations and ideas, necessarily dependent, and in the hands of the Supreme Being, infinitely more compliant to Him than clay is to the potter. I confess my ignorance, therefore; I avow that four thousand tomes of metaphysics will not teach us what our soul is. An orthodox philosopher said to a heterodox philosopher--"How have you been able to come to the point of imagining that the soul is mortal by nature, and eternal only by the pure wish of God?" "By my own experience," said the other. "How! are you dead?"
