Foucault’s posthumously-published late work on epimeleia heautou might inaugurate a new partnership between classicists and Foucault. This work, however, has been misconstrued in recent classical scholarship, an important instance of which I consider here. I remedy the errors of one of Foucault’s classical interpreters; diagnose the reasons for the errors; and briefly suggest the transformative potential of Foucault’s work for students of antiquity.
