Whether justice, as a general virtue, is essentially the same as all virtue?

❌ Objection 1 : It would seem that justice, as a general virtue, is essentially the same as all virtue. For the Philosopher says (Ethic. v, 1) that "virtue and legal justice are the same as all virtue, but differ in their mode of being." Now things that differ merely in their mode of being or logically do not differ essentially. Therefore justice is essentially the same as every virtue.

❌ Objection 2 : Further, every virtue that is not essentially the same as all virtue is a part of virtue. Now the aforesaid justice, according to the Philosopher (Ethic. v. 1) "is not a part but the whole of virtue." Therefore the aforesaid justice is essentially the same as all virtue.

❌ Objection 3 : Further, the essence of a virtue does not change through that virtue directing its act to some higher end even as the habit of temperance remains essentially the same even though its act be directed to a Divine good. Now it belongs to legal justice that the acts of all the virtues are directed to a higher end, namely the common good of the multitude, which transcends the good of one single individual. Therefore it seems that legal justice is essentially all virtue.

❌ Objection 4 : Further, every good of a part can be directed to the good of the whole, so that if it be not thus directed it would seem without use or purpose. But that which is in accordance with virtue cannot be so. Therefore it seems that there can be no act of any virtue, that does not belong to general justice, which directs to the common good; and so it seems that general justice is essentially the same as all virtue.
