'The world is more mobile than it has ever been and in many different fields, most notably literary studies, it has led to a growing, and now well established interest in cultural and ethnic mobility, diaspora, transnational and cosmopolitan interactions. This rise in global mobility at the same time as state borders have become more hysterically protected, has interested post-colonial cultural critics for some time. The concept of the nation, or at least the nation state, has often been robustly critiqued because the post-colonial nation is marked by disappointment, instituted on the boundaries of the colonial state and doomed to continue its oppressive functions. Almost universally the nation is contrasted with "the transnational" and the global movement of peoples. It is held to be a fixed entity, a pole of attraction or repulsion orienting transnational relationships at state level. But if we distinguish the nation from the state we discover that mobility and border crossing are already features of the phenomenon we call nation.' (Author's introduction)
