Whether particular justice has a special matter?

Objections

Objection 1 : It would seem that particular justice has no special matter. Because a gloss on Gn. 2:14, "The fourth river is Euphrates," says: "Euphrates signifies 'fruitful'; nor is it stated through what country it flows, because justice pertains to all the parts of the soul." Now this would not be the case, if justice had a special matter, since every special matter belongs to a special power. Therefore particular justice has no special matter.
Objection 2 : Further, Augustine says (Questions. lxxxiii, qu. 61) that "the soul has four virtues whereby, in this life, it lives spiritually, viz. temperance, prudence, fortitude and justice;" and he says that "the fourth is justice, which pervades all the virtues." Therefore particular justice, which is one of the four cardinal virtues, has no special matter.
Objection 3 : Further, justice directs man sufficiently in matters relating to others. Now a man can be directed to others in all matters relating to this life. Therefore the matter of justice is general and not special.
