He shows how rationality is in many strategic situations hard to define and often leads to paradoxes such as the prisoners dilemma, and explores rational beliefs about the international system. He examines theories of arms races, alliances, and the international problems of ecology. Here he is critical of the classical school of international relations for a lack of rigor in dealing with the problems of evidence and belief. Finally, Michael Nicholson discusses the philosophy of science, policy, and ethics. This book is both an exposition and a defense of a social scientific approach to international relations. With its emphasis on social scientific approaches, theory building and testing--and above all its clarity and accessibility--it provides students with a key to understanding the complex field of conflict analysis.Preface; Introduction: rationality and the analysis of conflict; Part I.
