Daedalus Summer 2008 ‘Cosmopolitanism’ is not–or not yet –the name of a determinate political philosophy. Although many contemporary theorists have put forward views that they describe as cosmopolitan, there is little agreement among them about the central elements of a cosmopolitan position. Almost nobody advocates the development of the kind of global state that would give the idea of ‘world citizenship’ literal application. Instead, disparate views have been advanced under the heading of cosmopolitanism, and these views share little more than an organizing conviction that any adequate political outlook for our time must in some way comprehend the world as a whole. To some people cosmopolitanism is primarily a view about sovereignty. To others it is primarily a view about culture and identity. To many philosophers, however, it is primarily a view about justice, and in recent years there has been an increasing flow of books and articles devoted to the subject of ‘global justice.’ In part, the focus on justice reflects the continuing influence of John Rawls, who insisted that “[j]ustice is the 1⁄2rst virtue of social institutions, as truth is of systems of thought.”1 In so doing, Rawls elevated the concept of justice above other important political ideas such as liberty, law, equality, power, rights, obligation, security, democracy, and the state, and gave it a privileged place on the agenda of contemporary political philosophy. It is testimony to Rawls’s influence that justice–especially ‘distributive,’ or economic, justice– has remained a central preoccupation of political philosophers ever since.
