The Dual Quality of Norms and Governance beyond the State: Sociological and Normative Approaches to ‘Interaction’

Abstract This essay develops a critique of modern constructivist approaches to norms in international relations theory. It distinguishes between a behaviourist and a societal perspective on norms. The former explains compliance with norms and/or norm diffusion via the logic of appropriateness and the logic of arguing, respectively, the latter understands divergence in normative meaning via the logic of contestedness. Using Habermas's approach to facts and norms as a framework, the article discusses the possibilities of legitimate governance based on core constitutional norms such as democracy, the rule of law and fundamental and human rights and their role in contexts beyond the modern nation‐state.
