"Crossing Boundaries", with contributions from some of the foremost thinkers in feminist theory, clearly and explicitly challenges existing disciplines and fields of study from a feminist perspective, contesting their presumptions and questioning and crossing their boundaries. It provides a broad-ranging overview of the current state of feminist interventions in the social and natural sciences and the humanities. It illustrates something of the diversity of approaches to theory and scholarship which is evident in the work of feminists. It analyses crucial problems in the way traditional knowledges are conceived, and poses exciting new alternatives. Here is a display of the current vigour of feminist investigations, from mathematics to literary criticism, from biology to socialism, from equal pay to polyandry. It will introduce the reader to the work of feminst thinkers; it will be a valuable text for students and teachers on gender studies courses.
