This chapter explores John Rawls’s political liberalism, a contemporary reworking of the idea of the social contract and one which straddles the boundary between Hobbesian rationality and Kantian reasonableness. The discussions cover the ‘fact of reasonable pluralism’; the ‘original position’ and Rawls’s political constructivism; the principles of justice; the stability of the liberal State; the stages of application of the political conception of justice; and justice and liberal legitimacy.
