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".
