In the Preface to A Theory of Justice, Rawls observes that “[d]uring much of modern moral philosophy the predominant systematic theory has been some formof utilitarianism” (TJ, p. vii/xvii rev.). Critics of utilitarianism, he says, have pointed out that many of its implications run counter to our moral convictions and sentiments, but they have failed “to construct a workable and systematic moral conception to oppose it” (TJ, p. viii/xvii rev.). As a result, Rawls writes, “we often seem forced to choose between utilitarianism and intuitionism.” In the end, he speculates, we are likely to “settle upon a variant of the utility principle circumscribed and restricted in certain ad hoc ways by intuitionistic constraints.” “Such a view,” he adds, “is not irrational; and there is no assurance that we can do better. But this is no reason not to try” (TJ, p. viii/xviii rev.). Accordingly, what he proposes to do “is to generalize and carry to a higher order of abstraction the traditional theory of the social contract as represented by Locke, Rousseau, and Kant.” Rawls believes that, of all traditional theories of justice, the contract theory is the one “which best approximates our considered judgments of justice.” His aim is to develop this theory in such a way as to “offer an alternative systematic account of justice that is superior . . . to the dominant utilitarianism of the tradition” (TJ, p. viii/xviii rev.).
