“Contractarianism/Contractualism is an extremely valuable collection of seminal works by the major representatives of the social contract tradition. The excellent texts are well chosen; together they provide a first-rate introduction to this important area of moral and political thought.” Samuel Freeman, University of Pennsylvania <!--end-->

“One of the most interesting attempts to explain moral obligation traces it to a form of contract or agreement. Darwall's collection reprints classic attempts to offer this kind of explanation by Hobbes, Rousseau, and Kant, along with more recent versions. The volume not only brings out the power of this approach to morality, but also usefully distinguishes a number of important variations of contractarian and contractualist accounts.” Gilbert Harman, Princeton University
