The “contractarian” view of social justice according to which social and economic inequalities should be regulated so that they serve to benefit the least advantaged follows as a corollary from            

Kant’s first principle of justice in “The Doctrine of Right” which states that justice consists in a reciprocal coercion of personal freedoms that results in the maximal or most extensive distribution of liberties under universal laws                      

Mill’s principle of utility in “Utilitarianism” which states that the good and right consists in what tends to produce the maximal predominance of quality pleasure over suffering for all that might be affected      

Aristotle’s theory of distributive justice in “The Nicomachean Ethics” which defines the rule of such justice as requiring a combination of the intellectual virtue of practical wisdom in decision making and the moral virtue of exercising the rational and appropriate degree of feeling and emotion in action
