Book excerpt: First published in 1992. Martin Griffiths' book provides a reinterpretation of the terms 'realism' and 'idealism' in international relations, and a thorough critical examination of three key figures in international theory: Hane Morgenthau, Kenneth Waltz and Hedley Bull. This is an important book proving a compelling basis for conceiving international politics as a 'rule-governed' arena among states. It will be of great interest to scholars and students of international relations.
