An evolution that invents as it goes
If the history of life is already contained in its causes or in its goal, then nothing has genuinely happened. Bergson asks what biology would have to admit for novelty to be real.
Mechanism reads a living form off the parts behind it, finalism off the end ahead of it, and one objection catches both: each assumes the result was given in advance, so neither leaves room for invention. In their place Bergson puts élan vital, a vital surge, one impulse running through everything alive and dividing as it goes into the torpor of plants, the instinct of animals, the intelligence of human beings. Biologists never accepted it, answering that the surge was too vague to work with.

Enter a dialogue
- Life is like an exploding shell whose fragments are themselves shells that burst again. What does that picture say about where evolution is heading?
- A child who fits together the pieces of a puzzle-picture may think he has made the picture. What does that show about explaining evolution from its finished parts?
- You divide life into the torpor of plants, the instinct of animals and the intelligence of humans. Does that ranking flatter our own branch beyond the evidence?
- A hive is so tightly organised that no bee lives long apart from it. Where does one organism end and a society of organisms begin?
