A close reading of Georges Canguilhem’s early writings, recently published in a new edition, reveals that at the end of the 1930s, before he became the philosopher of life we know, Canguilhem carried out a spectacular reassessment of Bergson. One must therefore ask what inspired this new reading, since, against expectations to the contrary, the common problem he shared with Bergson does not seem to have been the problem of life. In this paper, I attempt to show how Canguilhem’s new attitude to Bergson allowed him to transfer Bergson’s theory of knowledge over to the field of the philosophy of values, whose object is the unity of experience.
