ABSTRACT
In the preface to Time and Free Will Bergson says that his main subject is free will, which the third chapter deals with, but he leads up to it with two introductory chapters on intensity and duration. The second of these has an importance in his philosophy as a whole that belies the label ‘introductory’, as he agrees in his résumé at TF, 226. But the first, though added as an afterthought (Q, 1542), contains what might well be called the germ of the whole system.
