(c) justice follows a mean of the thing, the others a mean of reason;
(d) justice is had materially without any suitability to the circumstances of the agent, not so the other virtues.
1715. While justice is inferior to the theological and intellectual virtues (see 156, 157, 1028), it is superior to most of the moral virtues that perfect the sensitive or the intellectual appetite. The superiority of justice to fortitude, temperance, and the annexed virtues, such as mercy (see 1207), is seen from the following reasons.
(a) Legal justice is greater than those other virtues, for, while they pursue the private good of their subject, it seeks the public good. “Great is the splendor of justice,” says St. Ambrose (_De Officiis_, lib. I, cap. 28), “which is born for others rather than for itself, and which aids society and the community. It holds high position, that all may be subject to its judgment, that it may bestow assistance, not refuse responsibility, take upon itself the dangers of others.” Moreover, since the law commands us to perform the actions of the courageous man, of the gentle man and of the temperate man, legal justice, as Aristotle says (_Ethics_, lib. V, cap. 2), is often regarded as the supreme virtue, the summary of all the virtues, more glorious than the star of eve or dawn.
(b) Private justice is also greater than those other virtues, since it perfects a nobler power of the soul (viz., the will), and seeks the good, not only of its own possessor, but also of others. Justice too is impartial or blind as between persons, demanding satisfaction, even though a debtor be a monarch, and granting redress, even though an injured party be the humblest or most undeserving of mankind. An indication that justice is nobler than regulation of the passions is seen by Aristotle (_Ethics_, lib. V, cap. 4) in the fact that it is more difficult and rarer: “Many people are capable of exhibiting virtue at home, but incapable of exhibiting it in relation to their neighbor. Accordingly, there seems to be good sense in the saying of Bias, that ‘office will reveal a man,’ for one who is in office is at once brought into relation and association with others. As then the worst of men is he who exhibits his depravity both in his own life and in relation to his friends, the best of men is he who exhibits his virtue, not in his own life only, but in relation to others; for this is a difficult task.”
1716. Two virtues of the sensitive appetite that appear more excellent than justice are courage and liberality, but in reality justice is nobler than they.
(a) Thus, courage seems to be better, because it is more essential to the common good in time of great danger; but in reality justice is more useful to the community, for at all times, whether in peace or in war, it is justice that preserves unity and contentment among the people and promotes courage and devotion to the public welfare.
(b) Liberality seems to be better than justice, because it gives more than is due, while justice gives only what is due. But, on the other hand, justice is of more general advantage, since of necessity liberality must be exceptional and shown only to comparatively few, while justice must be exercised continually and must be shown to all; justice is also more necessary, for one must be just in order to be liberal, and not vice versa, since no one is praised as generous unless he first pays the debts of justice; finally, although liberality gives more than is due and may thus be a greater private benefit, justice without liberality is more serviceable to the common interest than liberality without justice.
1717. Two virtues of the will which some authorities hold to be more important than justice are the virtues of religion and mercy.
(a) The virtue of religion has a nobler object, since it regulates the worship owed to God, while justice regulates the things owed to man; and its obligation is stricter even than that of legal justice.
