Positions Luce Irigaray as one of the most important and radical political thinkers alive today This book analyses Irigaray's celebrated works alongside some of her lesser-known writings to make connections between the political, ethical and ontological dimensions of her philosophy. Laura Roberts argues that Irigaray's philosophical-political project must be read as a critique of constructions of Western modernity and rationality and that, when appreciated as such, her work makes significant contributions to key conversations in contemporary political movements and important strands in decolonial thought. This enables readers to recognise that the question of sexual difference in Irigaray's philosophy is concerned with not onlyrefiguring politics and political action but also the foundational structures that govern existence itself. Laura Roberts is Lecturer in Philosophy and Gender Studies at the University of Queensland, Australia.
