In this paper, I want to look at some questions that arise when we try to abandon the conceptual and political framework of the nation-state. Is it impossible to conceive the unity of the state apart from the unity of the nation? Are shared political values insufficient to account for the existence of bounded states and special duties to one's own country? In the first section I will discuss the view that the idea of the modern state is incoherent and (...) that it tacitly relies on the social idea of membership provided by the nation. The following section will give an alternative to the nationalist account of the exist ence of bounded communities and suggest why Habermasians and Rawlsians are right in thinking that the shared value of justice can be sufficient for political unity. Finally, I give a brief indication of the rel evance of this discussion to the idea of European Union. Key Words: boundaries. • collective intentionality • constitutional patriotism • European Union • liberal unity • post-national identity. (shrink)
