In a reading of René Descartes's The Passions of the Soul, Luce Irigaray explores the possibility that wonder, first of all passions, can provide the basis for an ethics of sexual difference because it is prior to judgment, and thus nonhierarchical. For Descartes, the passion of generosity gives the key to ethics. I argue that wonder should be extended to other differences and should be combined with generosity to form the basis of an ethics.
