ABSTRACT
This chapter investigates both the history of the idea of natural law as well as its modern interpretations in order to reveal two separate yet related ideas. Historically the ends of natural law morality have been used as a benchmark against which to critique customs and practices. This version of human morality is distinct from that of Augustine, a theologian who enjoys a prominent role in the discourses of international relations, in particular realist interpretations of international politics. This account of political authority sustains an account of international relationships that transcend the state structure. Cosmopolitan responses to human suffering reflect the necessary abridgment within politico-ethical frameworks of morality and power in international politics. The chapter concludes with an examination of the New Natural Lawyers in order to describe the value of their interpretation of natural law morality vis-a-vis the practices of international politics in general.
