II
We are emerging (to speak only of the last three or four centuries of our present civilization), we are emerging from the great religious period. During this period, despite the hopes laid beyond the tomb, human life stood out against a somewhat gloomy and threatening background. This background allowed the thousand mobile and diversely shaded curtains of art and metaphysics to intervene pretty freely between the last men and its faded folds. Its existence was to some extent forgotten. It no longer appeared in view save at the hour of the great rifts. Nevertheless, it always existed in the immanent state, giving a uniform colour to the atmosphere and the landscape and giving to human life a diffuse meaning which proposed a sort of provisional patience upon questions that were too pressing.
To-day, this background is disappearing in tatters. What is there in its place to give a visible form, a new meaning to the horizon?
The fallacious axis upon which humanity believed itself to revolve has suddenly snapped in two; and the huge platform which carries mankind, after swaying for some time in our alarmed imaginations, has quietly settled itself again to turning on the real pivot that had always supported it. Nothing is changed except one of those unexplained phrases with which we cover the things which we do not understand. Hitherto, the pivot of the world seemed to us to be made up of spiritual forces; to-day, we are convinced that it is composed of purely material energies. We flatter ourselves that a great revolution has been accomplished in the kingdom of truth. As a matter of fact, there has been, in the republic of our ignorance, but a permutation of epithets, a sort of verbal coup d'État, the words "mind" and "matter" being no more than the interchangeable attributes of the same unknown.
