 Although contemporary social contract theorists still sometimes employ the language of consent, the core idea of contemporary social contract theory is agreement. “Social contract views work from the intuitive idea of agreement” (Freeman 2007a, 17). One can endorse or agree to a principle without that act of endorsement in any way binding one to obey. Social contract theorists as diverse as Samuel Freeman and Jan Narveson (1988, 148) see the act of agreement as indicating what reasons we have; agreement is a “test” or a heuristic (see §5). The “role of unanimous collective agreement” is in showing “what we have reasons to do in our social and political relations” (Freeman 2007, 19). Thus understood, the agreement is not itself a binding act—it is not a performative that somehow creates obligation—but is reason-revealing (Lessnoff 1986). If individuals are rational, what they agree to reflects the reasons they have. In contemporary contract theories such as Rawls’s, the problem of justification takes center stage. Rawls’s revival of social contract theory in A Theory of Justice thus did not base obligations on consent, though the apparatus of an “original agreement” persisted. Recall that for Rawls (1999, 16) the aim is to settle “the question of justification … by working out a problem of deliberation.”
