Abstract

In this paper I propose a novel defence of political cosmopolitanism grounded in a familiar principle: universal moral equality. Critics of cosmopolitanism generally agree to universal moral equality, but disagree about what moral equality means politically. According to my argument, if we accept that all people are morally equal, then we ought to accept their equal moral standing. We should therefore prefer socio-political arrangements that reflect the equal moral standing of all people over those that reflect differentiated moral standing. A reasonable cosmopolitanism need not preclude partialist attachment to co-nationals, or undermine the significance of self-determination, so long as political arrangements do not produce differentiated moral standing. As the political application of an uncontroversial moral principle, I defend reasonable cosmopolitanism against nationalism and statism. Neither of these, I argue, are suitable foundations for global justice in migration because they each conceive of justice as a local concern for insiders.
