Abstract
Since his article, ‘Outline for a Decision Procedure in Ethics,’ John Rawls has advocated a coherentist moral epistemology according to which moral and political theories are justified on the basis of their coherence with our other beliefs, both moral and nonmoral. A moral theory which is maximally coherent with our other beliefs is in a state which Rawls calls ‘reflective equilibrium’. In A Theory of Justice Rawls advanced two principles of justice and claimed that they are in reflective equilibrium. He defended this claim by appeal to a hypothetical contract; he argued that parties in a position satisfying certain informational and motivational criteria, which he called ‘the original position,’ would choose the following two principles of justice to govern the basic structure of their society.
