Through historical studies of some of the work of Montesquieu, Comte, Durkheim, Boas, Morgenthau, Aron and Bourdieu, Derek Robbins examines the changing and competing conceptualisations of the political and the social in the Western European intellectual tradition. He suggests that we are now experiencing a new ‘dissociation of sensibility’ in which political thought and its consequences in action have become divorced from social and cultural experience. Developing further the ideas of Bourdieu which he has presented in books and articles over the last twenty years, Robbins argues that we need to integrate the recognition of cultural difference with the practice of international politics by accepting that the ‘field’ of international political discourse is a social construct which is contingent on encounters between diverse cultures. ‘Everything is relative’ (Comte) and ‘everything is social’ (Bourdieu), not least international politics.
