“In saying no to progress, it is not the future which they condemn, but themselves. They give themselves a melancholy disease; they inoculate themselves with the past. There is but one way of refusing tomorrow, that is to die.”

“The counterfeits of the past take assumed names, and are fond of calling themselves the future. That eternally returning spector, the past, not infrequently falsifies its passport.”

“They fathomed principle; they attached themselves to right. They longed for the absolute, they caught glimpses of the infinite realisations; the absolute, by its very rigidity, pushes the mind towards the boundless, makes it float in the illimitable. There is nothing like dream to create the future. Utopia today, flesh and blood tomorrow.”

“The realities of life do not allow themselves to be forgotten.”

“Children at once accept joy and happiness with quick familiarity, being themselves naturally all happiness and joy. ”

“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.”

“To understand the nature of the Revolution we must call it "progress"; and we may define progress by the word "tomorrow".”
