Why was one to be forced to affirm it?
Here everybody flatly refused help. Science seemed content with its old phrase of "larger synthesis," which was well enough for science, but meant chaos for man. One would have been glad to stop and ask no more, but the anarchist bomb bade one go on, and the bomb is a powerful persuader.
One could not stop, even to enjoy the charms of a perfect gas colliding seventeen million times in a second, much like an automobile in Paris.
Science itself had been crowded so close to the edge of the abyss that its attempts to escape were as metaphysical as the leap, while an ignorant old man felt no motive for trying to escape, seeing that the only escape possible lay in the form of vis a tergo commonly called Death. He got out his Descartes again; dipped into his Hume and Berkeley; wrestled anew with his Kant; pondered solemnly over his Hegel and Schopenhauer and Hartmann; strayed gaily away with his Greeks -- all merely to ask what Unity meant, and what happened when one denied it.
Apparently one never denied it. Every philosopher, whether sane or insane, naturally affirmed it. The utmost flight of anarchy seemed to have stopped with the assertion of two principles, and even these fitted into each other, like good and evil, light and darkness. Pessimism itself, black as it might be painted, had been content to turn the universe of contradictions into the human thought as one Will, and treat it as representation. Metaphysics insisted on treating the universe as one thought or treating thought as one universe; and philosophers agreed, like a kinetic gas, that the universe could be known only as motion of mind, and therefore as unity. One could know it only as one's self; it was psychology.
Of all forms of pessimism, the metaphysical form was, for a historian, the least enticing. Of all studies, the one he would rather have avoided was that of his own mind. He knew no tragedy so heartrending as introspection, and the more, because -- as Mephistopheles said of Marguerite -- he was not the first. Nearly all the highest intelligence known to history had drowned itself in the reflection of its own thought, and the bovine survivors had rudely told the truth about it, without affecting the intelligent.
One's own time had not been exempt. Even since 1870 friends by scores had fallen victims to it. Within five-and-twenty years, a new library had grown out of it. Harvard College was a focus of the study; France supported hospitals for it; England published magazines of it. Nothing was easier than to take one's mind in one's hand, and ask one's psychological friends what they made of it, and the more because it mattered so little to either party, since their minds, whatever they were, had pretty nearly ceased to reflect, and let them do what they liked with the small remnant, they could scarcely do anything very new with it. All one asked was to learn what they hoped to do.
Unfortunately the pursuit of ignorance in silence had, by this time, led the weary pilgrim into such mountains of ignorance that he could no longer see any path whatever, and could not even understand a signpost.
