"One of the clearest, most rigorous, and most original attempts to provide a rational foundation for morality in the history of moral philosophy....Promises to become one of the seminal works of twentieth-century moral philosophy."--International Studies in Philosophy

"[A] seminal contribution...to the sub-genre of contractarian social philosophy....Represents the culmination and synthesis of over two decades of work scattered throughout many journals and anthologies....Gauthier's book is the most ambitious attempt to date to ground social morality in something more rigorous than a set of coherentists' equilibrating reflections. As such it should be studied, as should the surrounding literature it will no doubt generate. Gauthier wields game and decision theory with aplomb, and provides excellent expositions of more technical points....It is, without doubt, one of the most important contributions to contractarian theory since Rawls' Theory of Justice."--Reason Papers

"Through a series of subtle yet entirely tough-minded arguments, Gauthier attempts to show that rational individuals will dispose themselves to be more, and they will do so not in contravention of their rationality but in its service....The philosophical skill with which he directs his argument is formidable....A signal contribution to moral philosophy....Rarely is the philosophical world graced with so sustained and strong an examination of foundational questions."--Critical Review

"This book presents a sophisticated contractarian moral theory, the most sophisticated yet developed in the tradition of Hobbes....There is a rapidly growing literature on Gauthier's theory, and the attention is well merited."--The Philosophical Review

"Possibly the most important book on the fundamental theory of justice in the last couple of centuries: the state-of-the-art presentation of the basic ideas of liberalism....Demands the careful attention of every serious student of these matters. It sets, indeed, a new standard of rigor and precision in moral philosophy."--International Philosophical Quarterly
