 Rawls gives special poignancy to this mutual commitment of the parties by making it a condition that the parties cannot choose and agree to principles in bad faith; they have to be able, not simply to live with and grudgingly accept, but instead to willingly endorse the principles of justice as members of society. Essential to Rawls’s argument for stability is the assumption of everyone’s willing compliance with requirements of justice. This is a feature of a well-ordered society. The parties are assumed to have a sense of justice; indeed the development and exercise of it is one of their fundamental interests. Hence they must choose principles that that they can not only accept and live with, but which are responsive to their sense of justice and they can unreservedly endorse. Given these conditions on choice, a party cannot take risks with principles he knows he will have difficulty complying with voluntarily. He would be making an agreement in bad faith, and this is ruled out by the conditions of the original position.
