Values in evolutionary biology: a comparison between the contemporary debate on organic progress and Canguilhem’s biological philosophy (original) (raw)

The aim of this paper is to make a comparison and build up a dialogue between two different philosophical approaches to values in evolutionary biology. First, I present the approach proposed by Alexander Rosenberg and Daniel McShea in their contribution to the contemporary debate on organic progress. i.e. the idea that there has been some kind of improvement concerning organisms over the history of life. Discussing organic progress raises the question of what “better” exactly means. This requires an explicit clarification on what legitimately means to speak about “good” in evolutionary biology, thus to speak about values. Second, I move on to present an approach to values that has been proposed by Georges Canguilhem in the context of a different philosophical tradition (i.e. the “continental” tradition). Canguilhem’s original theses are conceived in a Darwinian framework and clearly relate to the question of values in evolutionary biology. I shall then propose a comparison between t...
