Abstract

In the introduction to the Normal and the Pathological, Canguilhem’s doctoral dissertation in medicine, defended in 1943, he claimed, “philosophy is a reflection for which all unknown material [matière étrangère] is good.” In this case the “unknown material” was precisely medicine; “a technique or art at the crossroads of several sciences” which was supposed to provide “an introduction to concrete human problems.” Canguilhem had started studying medicine six years before, while he was a high-school professor in Toulouse. At the time he was distancing himself from the philosophical framework that had marked his studies and writings during the previous decade. This framework implied an anti-vitalist, Kantian and Cartesian approach to man, strongly influenced by his mentor Emile Chartier, also known as Alain. In this chapter, I try to provide concrete explanations concerning his decision to study medicine. I will not rely on those proposed by the existent scholarship, which frequently relate his decision to his interest in technology and technique. On the contrary, by examining unpublished material, such as a series of lectures given between 1933 and 1935, I claim that the motivation of his turn has to be related to the readings of works in psychology and ethology undertaken during this period.
