I favor a form of cosmopolitanism that takes nations very seriously, particularly because of the role of national law in sustaining or, unfortunately, undermining human rights. Some cosmopolitans take the metaphor of global citizenship - the etymology of the word, after all, just comes from a Greek phrase meaning citizen of the world - to rule out taking national citizenship seriously. I think that's a big mistake. Why can't I be loyal to America and to humanity? After all, I can be loyal to America and to New York city!
