'The most useful introduction I have seen of its kind. Readers can profit from the entire book, or use it as a reference to learn about institutions, the global economy, armed conflict and the similarities and differences among history, foreign policy and international relations, in practice and theory.' -- Richard Ned Lebow, Professor of International Political Theory, Kings College London 'Jones has written a superb introduction to the theory and practice of international relations. It is genuinely innovatory, transcending many of the current debates and reformulating the way that the subject is conventionally presented. By the end of the book he has laid bare the complex connections between theory and practice and demonstrated clearly and concisely the philosophical assumptions that necessarily underpin the field. It is an introduction that is both ground clearing and ground breaking.' -- Richard Little, Professor Emeritus in International Relations, University of Bristol
