Abstract

This paper brings Georges Canguilhem and Gilles Deleuze together with the contemporary biologist Mary Jane West-Eberhard. I examine the concepts of adaptation and adaptivity in Canguilhem’s The Normal and the Pathological in light of West-Eberhard’s notion of “developmental plasticity,” which is, I claim, adaptivity in the developmental register. In turn, I interpret Canguilhem’s notion of “comparative physiology” and West- Eberhard’s notion of an “eco-devo-evo” approach to biology in terms of Deleuze’s notion of multiplicity
