'This bears a modest title: Of Habit. But the author sets forth in it a whole philosophy of nature. What is nature? How is one to imagine its inner workings? What does it conceal under the regular succession of cause and effect? ...Ravaisson seeks the solution of this very general problem in a very concrete intuition, the one that we have of our own condition when we contract a habit...These ideas, like many we owe to Ravaisson, have become classic.' Henri Bergson
