This essay proposes contrasting the way in which Foucault conceives ethical subjectivation, as a form of resistance to biopower, and the way Hannah Arendt understands political singularization, as an interruption of the governance of life. In this way, this essay suggests that Arendt’s perspective exposes problems in Foucault’s argument, that Foucauldians do not seem to heed, and that Foucault’s point of view enables elaboration of some of the criticisms of Arendt’s ideas, which the Arendtians seem to avoid completely.
