Antigone fascinates G.W.F. Hegel and Luce Irigaray, both of whom turn to her in their explorations and articulations of ethics. Hegel and Irigaray make these re-turns to Antigone through the double and related lenses of nature and sexual difference. This essay investigates these figures of Antigone and the accompanying ethical accounts of nature and sexual difference as a way of examining Irigaray's complex relation to and creative uses of Hegel's thought.
