Is it possible and desirable to translate the basic principles underlying cosmopolitanism as a moral standard into effective global institutions. Will the ideals of inclusiveness and equal moral concern for all survive the marriage between cosmopolitanism and institutional power? What are the effects of such bureaucratisation of cosmopolitan ideals? This volume examines the strained relationship between cosmopolitanism as a moral standard and the legal institutions in which cosmopolitan norms and principles are to be implemented. Five areas of global concern are analysed: environmental protection, economic regulation, peace and security, the fight against international crimes and migration.
