The French existentialists Simone de Beauvoir and Jean‐Paul Sartre are renowned philosophers of freedom. But what “existentialist freedom” is is a matter of disagreement amongst their interpreters and, some argue, between Beauvoir and Sartre themselves. Since the late 1980s several scholars have argued that a Sartrean conception of freedom cannot justify the ethics of existentialism, adequately account for situations of oppression, or serve feminist ends. On these readings, Beauvoir disagreed with Sartre about freedom—making existentialist ethics, resistance to oppression, and feminism (...) coherently defensible. This article identifies four conceptions of freedom in order to clarify the questions of whether and how they disagreed, arguing that some incompatibilist readings of Sartre and Beauvoir conflate or confuse these conceptions in ways that render their conclusions unconvincing. However, there are stronger grounds on which to claim that Beauvoir disagreed with Sartre about morality—and the conditions of its possibility. (shrink)
