"Approaching Simone de Beauvoir's feminism and social commentary as a toolkit to understand our current crises, Simone de Beauvoir: Toolkit for the 21st Century brings together established and emerging scholars to apply her insights to gender studies, political philosophy, decolonisation, intellectual history, age theory, and critical phenomenology. The essays in this collection start from key concepts in Beauvoir's oeuvre and relate them to contemporary debates, asking how her notion of ambiguity speaks to decolonial freedom struggles; how myths inform our notions of collective, national identities; how masculinity and its violence has reached new levels with the emergence of 'Incels'. These and other issues are central to this critical appraisal of Beauvoir's legacy, demonstrating the contemporary relevance of her thought as it diagnoses the present and looks toward change for a better future. This book will be of great interest to undergraduate and postgraduate students looking to engage with the political content of Simone de Beauvoir's work and the timely application of her ideas"--
