The lectures on problems of moral philosophy delivered by Theodor W. Adorno in 1963 have garnered significant interest in recent years. Judith Butler, for instance, has used them as a starting point in her critique of ethical violence. Through an exploration of classical texts and positions in moral philosophy, Adorno examines the problematic status of moral philosophy itself. If there can be "no right life in the wrong," what does that mean for philosophizing about morality? How does moral philosophy as a theory relate to everyday morality as practice? Adorno did not publish any practical philosophy during his lifetime, and thus these lectures, which delve into the contradictions between theory and practice of a moral philosophy after Auschwitz, emerge as the work closest to a practical philosophy of Adorno.
