Our point of departure is a reservation concerning the validity of cosmopolitan ideas in response to 9/11. Cosmopolitanism in the social and political sciences plays an important role in the reconstruction of conceptual tools, the diagnosis of the current epoch and the creation of new normative standards. Its key motif, however, that of epochal change from a nationally-based to a cosmopolitan world order, is prematurely dismissive of traditional categories and assimilative of a normative vision. The separation of the present from the past is as overstated as is its conflation with the future.
