Is there a viable specifically feminist social theory that can serve as heuristic devise in our social research? This thesis is a critical reassessment of the ontological and normative assumptions of four social theories with specific and clear claims of being feminist. These are Catharine M MackInnon’s Radical Feminism, Anna G Jonasdottir’s Theory of Love Power, Luce Irigaray’s Feminism of Sexual Difference and Judith Butler’s Queer Feminism. The feminist social theories are examined and critically discussed according to their internal coherence and their external relevance; which includes the normative political implications that can be inferred. The thesis claims that implicit in every comprehensive feminist approach, there is also a specific view of science. Then follows a meta-inquiry of comprehensive feminisms as social science and as social theories, including a discussion of the effects of comprehensive ideology on social science research in general, and of the relationship between ideology, theory and a scientific approach in particular. The thesis concludes that it is highly problematic to do science feministly, but that we do need the critical questions feminists raise in order to reevaluate concepts, theories and research priorities. It is argued that feminist social theories are perhaps most helpful as ideological guidance for political action.
