This volume in political epistemology offers a comprehensive discussion of the multiple applicability of Gramscian concepts and categories to the historical, sociological, and cultural analysis of science. The authors argue that the perspective of hegemony and subalternity allows us critically to assess the political directedness of scientific practices as well as to reflect on the ideological status of disciplines that deal with science at a meta-level – historical, socio-historical, and epistemological.
