 Addressing the goals of feminist philosophy of law requires theory development, conceptual analysis, and conceptual revision. Promoting freedom and equality for women reflects a profound shift in basic assumptions about the nature of women and their proper place in the world: a shift from inequality to equality of the sexes, along with re-examination of what equality itself requires. It also requires re-examination of the understanding of sex, gender, and gender roles. Given the scope and detail of this change, feminist legal theory proceeds on multiple levels, from the pragmatic, concrete, and particular to the conceptual and ultimately visionary. Some of this writing appears in philosophy journals and monographs, but much also appears in journals in gender studies and feminism, generalist law reviews, and the many specialist law journals devoted to issues of gender and justice. This article begins with a brief overview of fundamental themes of feminist legal theory, followed by discussion of the evolution of views about needed institutional changes in several substantive areas of law:  political equality, immigration, and citizenship; marriage, reproductive rights, and commodification of the body; protection from violence; and economic rights.
