Think like a man of action, and act like a man of thought.

To exist is to change, to change is to mature, to mature is to go on creating oneself endlessly

Spirit borrows from matter the perceptions on which it feeds and restores them to matter in the form of movements which it has stamped with its own freedom.

To perceive means to immobilize... we seize, in the act of perception, something which outruns perception itself.

The eye sees only what the mind is prepared to comprehend.

There is no greater joy than that of feeling oneself a creator. The triumph of life is expressed by creation.

The present contains nothing more than the past, and what is found in the effect was already in the cause.
