Engaging the World explores Luce Irigaray's writings on sexual difference, deploying the resources of her work to rethink philosophical concepts and commitments and expose new possibilities of vitality in relationship to nature, others, and to one's self. The contributors present a range of perspectives from multiple disciplines such as philosophy, literature, education, evolutionary theory, sound technology, science and technology, anthropology, and psychoanalysis. They place Irigaray in conversation with thinkers as diverse as Charles Darwin, Claude Lévi-Strauss, Gilles Deleuze, René Decartes, and Avital Ronell. While every essay challenges Irigaray's thought in some way, each one also reveals the transformative effects of her thought across multiple domains of contemporary life.
