Abstract

John Rawls argued in A Theory of Justice that ‘justice as fairness … is likely to have greater stability than the traditional alternatives since it is more in line with the principles of moral psychology'. In support, he presented a psychology of moral development that was informed by a comprehensive liberalism. In Political Liberalism, Rawls confessed that the argument was 'unrealistic and must be recast'. Rawls, however, never provided a psychology of moral development informed by a specifically political liberalism, leaving it at a disadvantage with respect to comprehensive liberalism itself. I argue that no coherent account is available. But, because Rawls’s Liberal Principle of Legitimacy, along with its implied stricture against 'indoctrination in the pejorative sense', is a creature of ideal rather than non-ideal theory, the deficiency is far less significant than many would assume.
