And because diverse passions belonging to diverse powers, always belong to diverse virtues, as stated above (A. 4); therefore a difference of objects that corresponds to a difference of powers always causes a specific difference of virtues—for instance the difference between that which is good absolutely speaking, and that which is good and difficult to obtain. Moreover since the reason rules man's lower powers in a certain order, and even extends to outward things; hence, one single object of the passions, according as it is apprehended by sense, imagination, or reason, and again, according as it belongs to the soul, body, or external things, has various relations to reason, and consequently is of a nature to cause a difference of virtues. Consequently man's good which is the object of love, desire and pleasure, may be taken as referred either to a bodily sense, or to the inner apprehension of the mind: and this same good may be directed to man's good in himself, either in his body or in his soul, or to man's good in relation to other men. And every such difference, being differently related to reason, differentiates virtues.
Accordingly, if we take a good, and it be something discerned by the sense of touch, and something pertaining to the upkeep of human life either in the individual or in the species, such as the pleasures of the table or of sexual intercourse, it will belong to the virtue of temperance. As regards the pleasures of the other senses, they are not intense, and so do not present much difficulty to the reason: hence there is no virtue corresponding to them; for virtue, "like art, is about difficult things" (Ethic. ii, 3).
On the other hand, good discerned not by the senses, but by an inner power, and belonging to man in himself, is like money and honor; the former, by its very nature, being employable for the good of the body, while the latter is based on the apprehension of the mind. These goods again may be considered either absolutely, in which way they concern the concupiscible faculty, or as being difficult to obtain, in which way they belong to the irascible part: which distinction, however, has no place in pleasurable objects of touch; since such are of base condition, and are becoming to man in so far as he has something in common with irrational animals. Accordingly in reference to money considered as a good absolutely, as an object of desire, pleasure, or love, there is liberality: but if we consider this good as difficult to get, and as being the object of our hope, there is magnificence [*megaloprepeia]. With regard to that good which we call honor, taken absolutely, as the object of love, we have a virtue called philotimia, i.e. love of honor: while if we consider it as hard to attain, and as an object of hope, then we have magnanimity. Wherefore liberality and philotimia seem to be in the concupiscible part, while magnificence and magnanimity are in the irascible.
As regards man's good in relation to other men, it does not seem hard to obtain, but is considered absolutely, as the object of the concupiscible passions. This good may be pleasurable to a man in his behavior towards another either in some serious matter, in actions, to wit, that are directed by reason to a due end, or in playful actions, viz. that are done for mere pleasure, and which do not stand in the same relation to reason as the former. Now one man behaves towards another in serious matters, in two ways. First, as being pleasant in his regard, by becoming speech and deeds: and this belongs to a virtue which Aristotle (Ethic. ii, 7) calls "friendship" [*philia], and may be rendered "affability." Secondly, one man behaves towards another by being frank with him, in words and deeds: this belongs to another virtue which (Ethic. iv, 7) he calls "truthfulness" [*aletheia]. For frankness is more akin to the reason than pleasure, and serious matters than play. Hence there is another virtue about the pleasures of games, which the Philosopher calls eutrapelia (Ethic. iv, 8).
It is therefore evident that, according to Aristotle, there are ten moral virtues about the passions, viz. fortitude, temperance, liberality, magnificence, magnanimity, philotimia, gentleness, friendship, truthfulness, and eutrapelia, all of which differ in respect of their diverse matter, passions, or objects: so that if we add justice, which is about operations, there will be eleven in all.
Reply Obj. 1: All objects of the same specific operation have the same relation to reason: not so all the objects of the same specific passion; because operations do not thwart reason as the passions do.
Reply Obj. 2: Passions are not differentiated by the same rule as virtues are, as stated above.
Reply Obj. 3: More and less do not cause a difference of species, unless they bear different relations to reason.
Reply Obj. 4: Good is a more potent mover than evil: because evil does not cause movement save in virtue of good, as Dionysius states (Div. Nom. iv). Hence an evil does not prove an obstacle to reason, so as to require virtues unless that evil be great; there being, seemingly, one such evil corresponding to each kind of passion. Hence there is but one virtue, meekness, for every form of anger; and, again, but one virtue, fortitude, for all forms of daring. On the other hand, good involves difficulty, which requires virtue, even if it be not a great good in that particular kind of passion. Consequently there are various moral virtues about desires, as stated above. ________________________
