A famed political scientist's classic argument for a more cooperative world We assume that, in a world ruled by natural selection, selfishness pays. So why cooperate? In The Evolution of Cooperation, political scientist Robert Axelrod seeks to answer this question. In 1980, he organized the famed Computer Prisoners Dilemma Tournament, which sought to find the optimal strategy for survival in a particular game. Over and over, the simplest strategy, a cooperative program called Tit for Tat, shut out the competition. In other words, cooperation, not unfettered competition, turns out to be our best chance for survival. A vital book for leaders and decision makers, The Evolution of Cooperation reveals how cooperative principles help us think better about everything from military strategy, to political elections, to family dynamics.

Essays by prominent political theorists representing the two dominant schools of international relations, neoliberalism and neorealism.

This path-breaking book offers fresh insights into a perennial problem. At times, the absence of centralized international authority precludes attainment of common goals. Yet, at other times, nations realize mutual interests through cooperation under anarchy. Drawing on a diverse set of historical cases in security and economic affairs, the contributors to this special issue of World Politics not only provide a unified explanation of the incidence of cooperation and conflict, but also suggest strategies to promote the emergence of cooperation.

Robert Nozicka s Anarchy, State, and Utopia is a powerful, philosophical challenge to the most widely held political and social positions of our age ---- liberal, socialist and conservative.

International relations are generally understood as a realm of anarchy in which countries lack any superior authority and interact within a Hobbesian state of nature. In Hierarchy in International Relations, David A. Lake challenges this traditional view, demonstrating that states exercise authority over one another in international hierarchies that vary historically but are still pervasive today. Revisiting the concepts of authority and sovereignty, Lake offers a novel view of international relations in which states form social contracts that bind both dominant and subordinate members. The resulting hierarchies have significant effects on the foreign policies of states as well as patterns of international conflict and cooperation. Focusing largely on U.S.-led hierarchies in the contemporary world, Lake provides a compelling account of the origins, functions, and limits of political order in the modern international system. The book is a model of clarity in theory, research design, and the use of evidence. Motivated by concerns about the declining international legitimacy of the United States following the Iraq War, Hierarchy in International Relations offers a powerful analytic perspective that has important implications for understanding America's position in the world in the years ahead.

E.H. Carr's Twenty Years' Crisis is a classic work in International Relations. Published in 1939, on the eve of World War II, it was immediately recognized by friend and foe alike as a defining work in the fledgling discipline.

The issues and themes he develops in this book continue to have relevance to modern day concerns with power and its distribution in the international system. Michael Cox's critical introduction provides the reader with background information about the author, the context for the book, its main themes and contemporary relevance. Written with the student in mind, it offers a guide to understanding a complex, but crucial text.
