This essay focuses on the relationship between biopolitics and race theory. Starting from Foucault, many authors have considered totalitarian anti-Semitism as a depravity of biologism. This essay would like to challenge this all-too-simple positivist, materialist, and evolutionist picture of biopolitics in the Third Reich. It examines another "tradition" of racial theories, central to National Socialism, much closer to the revered Western philosophical tradition than Darwinism ever was. This kind of racism presents itself as the authentic heir of that "Metaphysics of (...) Form," which traces its roots back to classical antiquity, in particular to Plato's work. Through the analysis of some Platonist and racist texts the essay tries to point out the ambivalences that connect some of the assumptions of our philosophical tradition to Nazi totalitarianism.
