I Am not concerned in this paper to discover what is peculiarly western about western conceptions of a world moral order, but merely to assemble some ideas about morality that recur in western thought - which may or may not be features of other civilizations as well. It is my ignorance of other civilizations that prevents me from undertaking the seductively neat task of deciding what is unique about western values, but it is the same ignorance that saves me from making the mistake of arriving at what is essentially western by subtracting from its history that which it shares with other cultures. “Western Values in International Relations” is a field that has been pioneered by Martin Wight in such a way as to stay the hand of a glossator, but it is the word “universal” in my title that distinguishes the present undertaking from Wight's work. His aim was to follow some lines of thought derived from domestic politics in the West into the field of diplomacy and international relations. My aim is to pursue them further, beyond international society to world society, and to take into moral account not merely the state and the order of states, but also the individual and certain actors and institutions in world politics whose concerns have been regarded conventionally as falling outside the domain of ‘diplomacy and international relations’.
