Professor Sandra Harding, Women's Studies and Education, UCLA Multiculturalism, Postcolonialism, Feminism: Do they require new research epistemologies? The prevailing philosophies of science, with their theories of what should count as good method, were constriucted and institutionalised in the natural and social sciences mostly prior to the end of World War Two. It was only after the war that decolonization processes began to end formal European rule of much of the rest of the world, and that race- and gender-based civil rights movements arose in the US, Europe and many other places around the world.These economic , social and political changes generated needs for new kinds of knowledge about nature and social relations for the dominant groups as well as for those in the former colonies and in the race-and gender-based new social movements. Epistemological and political assumptions underlying the classical research methodologies were challenged by these social movements. Moreover, during the same period, the classical philosophies, histories and sociologies of the natural and social sciences were undergoing a critical reevaluation in Europe and the European diasporia - the 'post-Kuhnian' philosophies and social studies of the sciences, for short. This paper will point too important ways in which similar calls for new ways of thinking about research methodology have emerged from all of these post World War Two social/science movements. Yes, multiculturalism, postcolonialism and feminism join post-Kuhnian science studies to challenge the natural and social sciences to produce more empirically and theoretically adequate, and politically appropriate, research epistemologies.
