One instantly took a dislike to this shabby-looking bourgeois, with the harsh, irritable voice, but after awhile, as the lecture went on, one forgot him. It was not the profundity of the man’s knowledge, great though it was, that impressed one; or the subtlety of his reasoning or the lucidity of his expression, but his earnestness, his obvious disregard for everything earthly but Truth.
This was borne in on one by every expression of his face, every gesture of his body, every word and every tone and inflection of his voice.
This was the twelfth and last lecture of the course. It was on the “Brain Conceived as a Machine Pure and Simple.”
It was a cold and pitiless lecture, striking at the root of poetry and romance, speaking of religions, not religion, and utterly ignoring the idea which stands poised like a white-winged Victory over all other ideas—the Soul.
It was pitiless because it did these things, and it was terrible because it was spoken by Thénard, for he was just standing there, a little, oldish man, terribly convincing in his simplicity, absolutely without prejudice, as ready to acknowledge the soul and its attributes as to refuse them, standing there twiddling his horsehair watch-chain, and speaking from the profundity of his knowledge with, at his elbow, a huge army of facts, instances, and cases, not one of which did not support his logical deductions.
I wish I could print his lecture in full. I can only give some few sentences taken at haphazard from the peroration.
“The fundamental basis of all morality can be expressed by the words Left—or Right. ‘Shall I take the path to the right, when my child is being threatened with death by a pterodactyl, or shall I take the path to the left when a mastodon is threatening to put a foot on my dinner?’
“The prehistoric man asking himself that question in the dawn of time laid the foundation of the world’s morality. Do we know how he answered it? Yes—undoubtedly he saved his dinner.
“The prehistoric woman crouching in the ferns, wakened from sleep by the cries of her child on the left and the shouting of her man on the right, found herself face to face with the question, ‘Shall I court self-destruction in attempting to save It, or shall I seek safety with Him?’ Do we know how she answered that question? Undoubtedly she took the path to the left.
“The woman’s Right was the man’s Left, and she took it not from any motive of goodness but just because her child appealed to her as powerfully as his dinner appealed to the man. And which was the nobler instinct? In prehistoric times, gentlemen, they were both equally noble, for the instinct of the man was as essential to the fact that you and I are here gathered together in enlightened Paris, as the instinct of the woman.
