Feudal Europe, 800–1300: communal discourse and conflictual practices

The discipline of international relations faces a new debate of fundamental significance. After the realist challenge to the pervasive idealism of the interwar years and the social scientific argument against realism in the late 1950s, it is now the turn of critical theorists to dispute the established paradigms of international politics, having been remarkably successful in several other fields of social inquiry. In essence, critical theorists claim that all social reality is subject to historical change, that a normative discourse of understandings and values entails corresponding practices, and that social theory must include interpretation and dialectical critique. In international relations, this approach particularly critiques the ahistorical, scientific, and materialist conceptions offered by neorealists. Traditional realists, by contrast, find a little more sympathy in the eyes of critical theorists because they join them in their rejection of social science and structural theory. With regard to liberal institutionalism, critical theorists are naturally sympathetic to its communitarian component while castigating its utilitarian strand as the accomplice of neorealism. Overall, the advent of critical theory will thus focus the field of international relations on its “interparadigm debate†with neorealism.
