The fifth volume in the Fundamentals of Philosophy Series, Debating Sex and Gender by Georgia Warnke is a concise yet in-depth introduction to contemporary feminist thought on sex and gender. Featuring a lucid and accessible writing style, the book focuses on four historical debates: the relation and possible distinction between sex (biologically based) and gender (culturally based); questioning the binary (male-female) character of sex and gender; the idea of gender as a performance and as a performative; and the intersection of gender with race, class, and other features of identity. These discussions serve as guides for the first four chapters of the book. The fifth chapter strives to resolve the four issues by situating sex and gender within a broader theory of identity, arguing that sex and gender are ways of understanding who people are and do not define us any more than other characteristics do. Unique in its exploration of several different debates--and their relationship to each other--Debating Sex and Gender is ideal for use in a variety of feminist philosophy, women's studies, and gender studies courses.
