A consolidação da filosofia biológica de Georges Canguilhem

Georges Canguilhem does not start his publications in history of life sciences´ studies. In the first decades in which his thought was formulated (1920-1930), his work dealt with themes related to the philosophy of values and moral issues. However, as a result of internal and external events to his thinking, from the mid-1950s Canguilhem has established itself as one of the greatest exponents of socalled French historical epistemology, with a series of publications on the historical domain of the life sciences. In these studies, and in an increasingly evident way in his work, there is a decisive influence of Gaston Bachelard, to whom he barely reported in previous decades. It is also in this period that became consolidated his “biological philosophy”. This paper proposes to draw some consequences of this event in the sphere of Georges Canguilhem's philosophy.
