INTERNATIONAL POLITICS: POWER AND PURPOSE IN GLOBAL AFFAIRS, 4th Edition, is a highly engaging introduction to the study of world politics. Author Paul D'Anieri uses the theme of Power and Purpose to examine five paradigms of international relations theory and to connect the scholarly analysis of international politics to policy problems and contemporary affairs. A cohesive pedagogical framework presents the study of international politics as a series of intellectual puzzles and policy problems and helps students make the connections between theory and policy; between history and the present; and between ideals and constraints. The author also addresses common student deficiencies in history, policy, and geography through case studies of real-world events, and emphasizes that a better understanding of international relations can often be gained by examining problems from multiple approaches.
