This book introduces readers to the concepts of political philosophy - authority, democracy, freedom and its limits, justice, feminism, multiculturalism, and nationality. Accessibly written and assuming no previous knowledge of the subject, it encourages the reader to think clearly and critically about the leading political questions of our time.

An exposition of modern game theory suitable for advanced undergraduates. The book emphasizes the ideas behind the theory rather than their mathematical expression, but defines all concepts precisely. It covers strategic, extensive and coalitional games and includes the topics of repeated games, bargaining theory and evolutionary equilibrium.
