Abstract

Simone de Beauvoir's account of biology in The Second Sex offers a nuanced and well‐developed phenomenological account of the lived experience of sexual difference. It is an account of biology that recognizes the importance of embodiment for the experience of freedom, and also recognizes the ways that particular bodies shape those experiences. She provides clarity about why biology matters, and why the fact that it matters does not mean that it determines our sense of self or identity. Beauvoir's thought offers important resources for contemporary scientific discussions of sex and sexuality, as can be seen by its close parallels to the view of sexual identity developed by Anne Fausto‐Sterling. It also offers an important vantage point for critiquing the simplistic, deterministic accounts of sex differences found in contemporary evolutionary psychology.
