My only knowledge of Henri Bergson is from perhaps a less intellectual source, the Monty Python sketch 'Spot the brain cell':

Cleese: ... Well your first question for the blow on the head this evening is: What great opponent of Cartesian dualism resists the reduction of psychological phenomena to physical states?

Jones: I don't know that!

Cleese: Well, have a guess.

Jones: Henri Bergson.

Cleese: Is the correct answer!

Jones: Ooh, that was lucky. I've never even heard of him.
