This reader has been assembled in response to increasing dissatisfaction among a growing number of international relations scholars with the currently dominant theory of realism as well as in recognition of the large number of newly independent states which are having to write new constitutions and develop foreign relations. The book includes excerpts and essays from political theory and international relations which provide a starting point for further study of these subjects. It draws together writings representing two distinct traditions and demonstrates their interconnections. In political theory, excerpts are drawn from classical texts which have an important bearing on problems of international relations. In international relations, the collection includes essays which have had a seminal influence on the development of this discipline. The editors firmly believe that there is much to be learned from the interface between international relations and political theory and they argue that, although regarded by some as two distinct fields, their subject matter is one: the nature of human conduct in a global context.
