Contemporary Contractarian Moral Theory 1 by

Contractarianism, as a general approach to moral and political thought, has had a long and distinguished history -its roots are easily traced as far back as Plato's Republic, where Glaucon advanced it as a view of justice, and its influential representatives include Pufendorf, Hobbes, Locke, Rousseau, Hume, and Kant. In various ways, to various purposes, and against the background of various assumptions, each of these philosophers offered contractarian arguments for the views they defended. What binds the tradition together, in the face of this variety, is the conviction that moral norms or political institutions find legitimacy, when they do, in their ability to secure (under the appropriate conditions) the agreement of those to whom they apply.
