The social sciences and humanities worldwide are discovering the necessity to self-critically reshape their theorizing: The first critique of social science theorizing calls for ¿globalizing¿, the second, parallel critique, for ¿de-colonizing¿ social thought. In his highly topical book, Michael Kuhn discusses · why and how the ¿globalization¿ of social science theorizing introduces thinking through nation state perspectives as an up-to-date methodological must; · how the ¿de-colonialization¿ of social science theorizing with the critique of Eurocentrism and its thinking through space paves the way for the worldwide implementation of thinking through nation-state views, transforming the social science world into a multiplicity of ¿provincialized¿ theories; · with which odd argumentations the ¿indigenization¿ of thought produces contributions to the ideological armament of the new states in the so-called 3rd world after their transformation into the very society system of the former colonizers; · how these indigenized theories make discourses among de-colonized theories a matter of which ¿provincialized¿ theory manages to rule the worldwide creation of theories; · how the masterminds of globally de-colonized thinking present imperial thought as guiding theories for mankind¿s thinking; · what templates for the turn from anti-capitalist towards nationalistic thinking Historical Materialism has provided, and · what consequences all this has for the social sciences as a voice in political debates about the world.
