Molly Cochran offers an account of the development of normative theory in international relations over the past two decades. In particular, she analyzes the tensions between cosmopolitan and communitarian approaches to international ethics, paying attention to differences in their treatments of a concept of the person, the moral standing of states and the scope of moral arguments. The book draws connections between this debate and the tension between foundationalist and antifoundationalist thinking and offers an argument for a pragmatic approach to international ethics.
