Feminist theory is the extension of feminism into theoretical, fictional, or philosophical discourse. It aims to understand the nature of gender inequality. It examines women's and men's social roles, experiences, interests, chores, and feminist politics in a variety of fields, such as anthropology and sociology, communication, media studies, psychoanalysis, political theory, home economics, literature, education, and philosophy. Feminist theory often focuses on analyzing gender inequality. Themes often explored in feminist theory include discrimination, objectification (especially sexual objectification), oppression, patriarchy, stereotyping, art history and contemporary art, and aesthetics. History Feminist theories first emerged as early as 1794 in publications such as A Vindication of the Rights of Woman by Mary Wollstonecraft, "The Changing Woman", "Ain't I a Woman", "Speech after Arrest for Illegal Voting", and so on. "The Changing Woman" is a Navajo Myth that gave credit to a woman who, in the end, populated the world. In 1851, Sojourner Truth addressed women's rights issues through her publication, "Ain't I a Woman". Sojourner Truth addressed the issue of women having limited rights due to men's flawed perception of women. Truth argued that if a woman of color can perform tasks that were supposedly limited to men, then any woman of any color could perform those same tasks. After her arrest for illegally voting, Susan B. Anthony gave a speech within court in which she addressed the issues of language within the constitution documented in her publication, "Speech after Arrest for Illegal voting" in 1872. Anthony questioned the authoritative principles of the constitution and its male-gendered language. She raised the question of why women are accountable to be punished under law but they cannot use the law for their own protection (women could not vote, own property, nor maintain custody of themselves in marriage). She also critiqued the constitution for its male-gendered language and questioned why women should have to abide by laws that do not specify women. Nancy Cott makes a distinction between modern feminism and its antecedents, particularly the struggle for suffrage. In the United States she places the turning point in the decades before and after women obtained the vote in 1920 (1910–1930). She argues that the prior woman movement was primarily about woman as a universal entity, whereas over this 20-year period it transformed itself into one primarily concerned with social differentiation, attentive to individuality and diversity. New issues dealt more with woman's condition as a social construct,
