Feminism is a collection of movements aimed at defining, establishing, and defending equal political, economic, and social rights for women. Existentialism is a philosophical and cultural movement which holds that the starting point of philosophical thinking must be the individual and the experiences of the individual, that  moral thinking and scientific thinking together are not sufficient for understanding all of human existence, and, therefore, that a further set of categories, governed by the norm of authenticity, is necessary to understand human existence. (Authenticity, in the context of existentialism, is being true to one's own personality, spirit, or character.) This philosophy analyzes relationships between the individual and things, or other human beings, and how they limit or condition choice.
