In "Bodies That Matter," Judith Butler further develops her distinctive theory of gender by examining the workings of power at the most "material" dimensions of sex and sexuality. Deepening the inquiries she began in "Gender" "Trouble," Butler offers an original reformulation of the materiality of bodies, examining how the power of heterosexual hegemony forms the "matter" of bodies, sex, and gender. Butler argues that power operates to constrain "sex" from the start, delimiting what counts as a viable sex. She offers a clarification of the notion of "performativity" introduced in "Gender Trouble" and explores the meaning of a citational politics. The text includes readings of Plato, Irigaray, Lacan, and Freud on the formation of materiality and bodily boundaries; "Paris is Burning," Nella Larsen's "Passing," and short stories by Willa Cather; along with a reconsideration of "performativity" and politics in feminist, queer, and radical democratic theory.

Since its publication in 1990, Gender Trouble has become one of the key works of contemporary feminist theory, and an essential work for anyone interested in the study of gender, queer theory, or the politics of sexuality in culture. This is the text where Judith Butler began to advance the ideas that would go on to take life as "performativity theory," as well as some of the first articulations of the possibility for subversive gender practices, and she writes in her preface to the 10th anniversary edition released in 1999 that one point of Gender Trouble was "not to prescribe a new gendered way of life [...] but to open up the field of possibility for gender [...]" Widely taught, and widely debated, Gender Trouble continues to offer a powerful critique of heteronormativity and of the function of gender in the modern world.
