Abstract
This chapter asks the reader to contrast justice with some of the other central virtues—for instance, prudence, courage, temperance, or wisdom. Justice is different. Unlike these others, it is principally a social virtue; its interpersonal element is central. Other virtues, such as generosity, as well as benevolence or charity, are also interpersonal. But unlike justice, acts of generosity or benevolence are not owed to specific people. One ought to help others, but the choice of when and where to act benevolently is for the most part up to the individual. In modern terms their requirements are duties of imperfect obligation; those of justice are for the most part owed to specific individuals. The thesis that the norms of justice are not always preemptive reasons may appear much less plausible regarding certain central norms of justice, for instance, the principle prohibiting the intentional killing of nonthreatening innocent persons. The same may be true with the prohibition of cruelty.
