In the 1960s and 1970s, activists who focused on the academy as a key site for fostering social change began by querying the assumptions of the traditional disciplines and transforming their curricula, putting into place women's and ethnic studies programs that changed both the subject and methods of scholarship. The pattern of scholars and activists joining forces to open fields of research and teaching continued in subsequent decades, and recent additions, including critical race studies, queer studies, cultural studies, and postcolonial studies, take as their epistemological foundation the inherently political nature of all knowledge production. Interdisciplinarity and Social Justice seizes this opportune moment in the history of interdisciplinary fields to review their effects on our intellectual and political landscape, to evaluate their ability to deliver promised social benefits, and to consider their futures. The essays collected in this volume detail histories of the interdisciplinary fields that emerged from social movements, examine how effectively they have achieved their goals of intellectual and social change, and consider the challenges they now face inside and outside the academy.
