This book examines the most significant metaphors of modern political philosophy: the state of nature and the social contract. Each of the main chapters is dedicated to the political theory of the different social contract thinkers and the ways they articulated the uniquely liberal view of equality and freedom. The last chapter, unique to most books that explore the social contract, highlights the recent challenges to these views. It is this balance between accepted contractarian ideas and their critiques that makes this book a unique contribution to the field of political philosophy.
