Sister Outsider: Essays and Speeches is a collection of essential essays and speeches written by Audre Lorde, a writer who focuses on the particulars of her identity: Black woman, lesbian, poet, activist, cancer survivor, mother, and feminist. This collection, now considered a classic volume of Lorde's most influential works of non-fiction prose, has had a groundbreaking impact in the development of contemporary feminist theories. In fifteen essays and speeches dating from 1976 to 1984, Lorde explores the complexities of intersectional identity, while explicitly drawing from her personal experiences of oppression to include sexism, heterosexism, racism, homophobia, classism, and ageism. The book examines a broad range of topics, including love, self-love, war, imperialism, police brutality, coalition building, violence against women, Black feminism, and movements towards equality that recognize and embrace differences as a vehicle for change. With meditative conscious reasoning, Lorde explores her misgivings for the widespread marginalization deeply-rooted in the United States' white patriarchal system, all the while, offering messages of hope. The essays in this landmark collection are extensively taught and have become a widespread area of academic analysis. Lorde's philosophical reasoning that recognizes oppressions as complex and interlocking designates her work as a significant contribution to critical social theory.
