Le Deuxième Sexe
Central to feminism is the idea that women are systematically subordinated, and bad faith exists when women surrender their agency to this subordination, e.g., acceptance of religious beliefs that a man is the dominant party in a marriage by the will of God; Simone de Beauvoir labels such women "mutilated" and "immanent". Simone de Beauvoir developed modern conceptions of bad faith and modern feminism together in her book "The Second Sex".
