This chapter explores Shulamith Firestone’s 1970 feminist manifesto The Dialectic of Sex, which provided an analysis of women’s oppression. The chapter introduces the Women’s Liberation Movement and its strands of liberal, socialist, and radical feminism. According to Firestone’s thesis, the origins of women’s oppression lie in their procreative capacities. The chapter also details Firestone’s vision for a utopian society created through a feminist revolution in which women seize control of reproductive technologies. The chapter highlights the significance of The Dialectic of Sex in relation to queer politics and movements for reproductive justice despite its flaws, notably its treatment of race.
