Abstract
Simone de Beauvoir and Jean-Paul Sartre struggled for the whole of their philosophical careers against one of modern Western philosophy's most pervasive concepts, the Cartesian notion of self. A notion of self is always a complex of ideas; in the case of Beauvoir and Sartre it includes the ideas of embodiment, temporality, the Other, and intersubjectivity. This essay will show the considerable part that gender, especially Beauvoir's position as a woman in twentieth-century France, played in the development, presentation and reception of the couple's alternative formulation.
