Abstract
Recent work in social science challenges managerial assumptions about homogenous knowledge domains, and traces the effects of a world economy of knowledge structured by the history of colonialism and current north-south global inequalities. The differentiation of knowledge rests on the very different histories and situations of metropolitan, creole, colonized and post-colonial intelligentsias. Different knowledge projects have been constructed in global space, which feed back on our understanding of knowledge itself. Less recognized, but increasingly important, are uses of southern and postcolonial perspectives in applied social science, in areas ranging from education to urban planning. Some implications of these applications are discussed: southern theory is not a fixed set of propositions but a challenge to develop new knowledge projects and new ways of learning with globally expanded resources.
