John Rawls's theory of justice is best understood as an attempt to adapt Rousseau's theory of the general will to the modern liberal democratic state. Central to the theory is a belief in the rationality of human nature and dynamics. In a well-ordered society men's natural sentiments will prove to be both unified and stable, and they will not permit morally arbitrary advantages to influence their social arrangements. Rawls's theory offers a rational accommodation of freedom and equality. His philosophical perspective opens him to the charge that his theory slights the historical dimension of human justice. His conception of human personality is somewhat ambiguous. There is incongruity between his ethical theory and the realities of democratic politics. Nevertheless, Rawls's formulation of the moral and political principles of liberalism is a major achievement and entirely worthy of his intellectual ancestry
