Postcolonial, gender and science studies have long been neglected in German sociology and kept separate in special discourses with regard to their different studied phenomena. Nevertheless are their heuristics very similar: They discuss the differentiation of nature and culture, decentralize the 'classical' concept of the subject and criticize the 'Western' project of modernity. This convergence of postcolonial, gender and science studies will be developed systematically in this article with reference to their central concepts. Furthermore it will be asked which blind spots of sociology it can illuminate and where the limits of their renewal of social theory are.
