Henri Bergson

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

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

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

Doubt is part of all religion. All the religious thinkers were doubters.

Wit is the appearance, the external flash of imagination. Thus its divinity, and the witty character of mysticism.

I think it would be funny for people to read in obituaries of me that my major contribution to the arts was the popularization of the phrases 'neutral facial expression' and 'screaming in agony.'
