Justice, Legitimacy, and Self-Determination: Moral Foundations for International Law. By Allen Buchanan. New York: Oxford University Press, 2004. 520p. $35.00.

Allan Buchanan is well known for his work on justice, secession, and self-determination. The volume under review draws on and builds upon his past work, developing and updating previously stated positions and setting new ground in formulating a moral approach to international law. The title of the book clearly encapsulates its content and the intentions of the author. Buchanan's first line in the book explains that it is “an attempt to develop moral foundations for international law” (p. 1). Undoubtedly this is a formidable and complex task, but one to which he skillfully addresses himself. His goal is to set out manageable frameworks for establishing and developing ideas and practices of justice and legitimacy that, in turn, will act as guiding principles in international law and relations. He certainly succeeds in achieving this and goes even further to set out interesting and provocative suggestions for reform of the international system. In short, this book is to be highly recommended, if not required, reading for anyone interested in the future of the international system.
