“In this nineteenth century, the religious idea is undergoing a crisis. People are unlearning certain things, and they do well, provided that, while unlearning them they learn this: There is no vacuum in the human heart. Certain demolitions take place, and it is well that they do, but on condition that they are followed by reconstructions.

In the meantime, let us study things which are no more. It is necessary to know them, if only for the purpose of avoiding them. The counterfeits of the past assume false names, and gladly call themselves the future. This spectre, this past, is given to falsifying its own passport. Let us inform ourselves of the trap. Let us be on our guard. The past has a visage, superstition, and a mask, hypocrisy. Let us denounce the visage and let us tear off the mask.”
