 Rawls says, “An important feature of a conception of justice is that it should generate its own support. Its principles should be such that when they are embodied in the basic structure of society, people tend to acquire the corresponding sense of justice and develop a desire to act in accordance with its principles. In this case a conception of justice is stable” (TJ, 138/119). The parties in the original position are to take into account the “relative stability” of a conception of justice and the society that institutes it. The stability of a just society does not mean that it must be unchanging. It means rather that in the face of inevitable change members of a society should be able to maintain their allegiance to principles of justice and the institutions they support. When disruptions to society do occur (via economic crises, war, natural catastrophes, etc.) and/or society departs from justice, citizens’ commitments to principles of justice are sufficiently robust that just institutions are eventually restored. The role of the stability requirement for Rawls is twofold: first, to test whether potential principles of justice are compatible with human natural propensities, or our moral psychology and general facts about social and economic institutions; and second, to determine whether principles are conducive to realizing the human good.
