 One consequence of Rawls’s great work, A Theory of Justice (1999 [first published in 1971]) is that the ‘new liberalism’ has become focused on developing a theory of social justice. Since the 1960s when Rawls began to publish the elements of his emerging theory, liberal political philosophers have analyzed, and disputed, his famous ‘difference principle’ according to which a just basic structure of society arranges social and economic inequalities such that they are to the greatest advantage of the least well off representative group (1999b:266). For Rawls, the default is not liberty but rather an equal distribution of (basically) income and wealth; only inequalities that best enhance the long-term prospects of the least advantaged are just. As Rawls sees it, the difference principle constitutes a public recognition of the principle of reciprocity: the basic structure is to be arranged such that no social group advances at the cost of another (2001: 122–24). Many followers of Rawls have focused less on the ideal of reciprocity than on the commitment to equality (Dworkin, 2000). Indeed, what was previously called ‘welfare state’ liberalism is now often described as liberal egalitarianism. However, see Jan Narveson’s essay on Hobbes’s seeming defense of the welfare state (in Courtland 2018) for historical reflections on the difference.
