Justice is happiness according to virtue.

I have tried to set forth a theory that enables us to understand and to assess these feelings about the primacy of justice. Justice as fairness is the outcome: it articulates these opinions and supports their general tendency.

Peace surely is a good reason, yes. But there are other reasons too.

The concept of justice I take to be defined, then, by the role of its principles in assigning rights and duties and in defining the appropriate division of social advantages. A conception of justice is an interpretation of this role.

The intolerant can be viewed as free-riders, as persons who seek the advantages of just institutions while not doing their share to uphold them.

Thus I assume that to each according to his threat advantage is not a conception of justice.

The sense of justice is continuous with the love of mankind.
