The emergence of ‘global ethics’ marks one high point in the current study of World Politics. Originally started in the separate realms of Political Philosophy and of International Relations, the streams have converged into a wider project to explore an acceptable framework to support activities on a global scale. The result thus has been an expanding literature advocating global morality, defending it against communitarian and other camps, setting up more sophisticated theories to provide ethical reasons for particular deeds and situations, and applying these frameworks to a variety of phenomena. Once recognised as naïve and somewhat idealistic, the study of ethics in a global context is forming a firm foundation to advance our understanding on the figuration and transformation of the world.
