: This essay focuses on some important concepts in Beauvoir's philosophy: ambiguity, desire, and appeal (appel). Ambiguity and appeal, concepts originating in Beauvoir's moral philosophy, are in The Second Sex connected to the female body and feminine desire. This indicates the complexity of Beauvoir's image of femininity. This essay also proposes a comparative reading of Beauvoir's and Sartre's concepts of appeal, a reading that indicates differences in their views of the relationship among ethics, desire, and gender.
