AD> Age and aging are pressing social-political issues. Yet, philosophers still have not paid sufficient attention to one of the major explorations of this topic, Simone de Beauvoir's seminal work The Coming of Age (1970). For much too long, it has been overshadowed by her other groundbreaking work, The Second Sex (1949). Now, for the first time, this volume focuses on Beauvoir's essay on old age and critically explores its significance from a phenomenological and feminist perspective. International Beauvoir scholars and renowned feminist phenomenologists from Europe and North America offer a unique look at one of the 20th century's most outstanding existential-philosophical studies on age and aging. Thematically, the articles and short comments collected in this volume cover three main issues which are crucial with respect to an investigation of Beauvoir's study on age: gender, ethics, and time. The volume essentially contributes to Beauvoir studies, aging studies, cultural and gender studies, feminist theory, phenomenology, and existential philosophy.
