The old world is dying, and the new world struggles to be born; now is the time of monsters

I'm a pessimist because of intelligence, but an optimist because of will.

The crisis consists precisely in the fact that the old is dying and the new cannot be born

To tell the truth is revolutionary.

Revolutionaries see history as a creation of their own spirit, as being made up of a continuous series of violent tugs at the other forces of society - both active and passive, and they prepare the maximum of favourable conditions for the definitive tug (revolution).

Man is above all else mind, consciousness -- that is, he is a product of history, not of nature.
