Feminist theory is the extension of feminism into theoretical or philosophical discourse. It aims to understand the nature of gender inequality. It examines women's social roles, experience, interests, and feminist politics in a variety of fields, such as anthropology and sociology, communication, psychoanalysis, economics, literature, education, and philosophy. While generally providing a critique of social relations, much of feminist theory also focuses on analyzing gender inequality and the promotion of women's interests. Themes explored in feminism include discrimination, objectification (especially sexual objectification), oppression, patriarchy, stereotyping, art history and contemporary art, and aesthetics.
