Aims to familiarise students with the principal theoretical responses to current changes in the international political order and the implications this has for domestic political theory. Examines current varieties of cosmopolitan political thought as responses to the deficiencies in theories of justice and citizenship which overtly or implicitly assume the nation state as the basis of political order. Addresses debates over the concepts of sovereignty, citizenship and cosmopolitan political order, as well as the complex relations between these concepts. Examines some sources of contemporary cosmopolitan thought in the philosophy of the Enlightenment. Compares and contrasts different approaches to these issues as an exercise in the methodology of political philosophy.
