'This is a tremendous little book. It deals with many of the profound political and normative questions confronting the study of international relations today, offering a well-argued scepticism which does not degenerate into crude realism or nihilism. It is a book which I would happily recommend to my graduate and undergraduate students alike.'Anthony McGrew, Professor of International Relations, University of Southampton "This is a little book that reflects long and hard thinking about difficult subjects. It will repay more than one reading and represents an important contribution to the canon of works from the English school of International Relations." Richard Little, University of Bristol "This impressive essay address some of the most perplexing normative questions that have arisen in world politics since the end of the Cold War... (a) timely and probing critique of the progressive international temper of our times should be read and pondered by anyone who takes an interest in the ethics of contemporary world politics."
