Henri Bergson

"In just the same way the thousands of successive positions of a runner are contracted into one sole symbolic attitude, which our eye perceives, which art reproduces, and which becomes for everyone the image of a man who runs."

"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."

"You will obtain a vision of matter that is perhaps fatiguing for your imagination, but pure and stripped of what the requirements of life make you add to it in external perception."

"Instinct perfected is a faculty of using and even constructing organized instruments intelligence perfected is the faculty of making and using unorganized instruments."

"Intelligence is the faculty of making artificial objects, especially tools to make tools."
