Reply Obj. 3: Although beauty is becoming to every virtue, it is ascribed to temperance, by way of excellence, for two reasons. First, in respect of the generic notion of temperance, which consists in a certain moderate and fitting proportion, and this is what we understand by beauty, as attested by Dionysius (Div. Nom. iv). Secondly, because the things from which temperance withholds us, hold the lowest place in man, and are becoming to him by reason of his animal nature, as we shall state further on (AA. 4, 5; Q. 142, A. 4), wherefore it is natural that such things should defile him. In consequence beauty is a foremost attribute of temperance which above all hinders man from being defiled. In like manner honesty [*Honesty must be taken here in its broad sense as synonymous with moral goodness, from the point of view of decorum] is a special attribute of temperance: for Isidore says (Etym. x): "An honest man is one who has no defilement, for honesty means an honorable state." This is most applicable to temperance, which withstands the vices that bring most dishonor on man, as we shall state further on (Q. 142, A. 4). _______________________
THIRD ARTICLE [II-II, Q. 141, Art. 3]
Whether Temperance Is Only About Desires and Pleasures?
Objection 1: It would seem that temperance is not only about desires and pleasures. For Tully says (De Invent. Rhet. ii, 54) that "temperance is reason's firm and moderate mastery of lust and other wanton emotions of the mind." Now all the passions of the soul are called emotions of the mind. Therefore it seems that temperance is not only about desires and pleasures.
Obj. 2: Further, "Virtue is about the difficult and the good" [*Ethic. ii, 3]. Now it seems more difficult to temper fear, especially with regard to dangers of death, than to moderate desires and pleasures, which are despised on account of deadly pains and dangers, according to Augustine (QQ. 83, qu. 36). Therefore it seems that the virtue of temperance is not chiefly about desires and pleasures.
Obj. 3: Further, according to Ambrose (De Offic. i, 43) "the grace of moderation belongs to temperance": and Tully says (De Offic. ii, 27) that "it is the concern of temperance to calm all disturbances of the mind and to enforce moderation." Now moderation is needed, not only in desires and pleasures, but also in external acts and whatever pertains to the exterior. Therefore temperance is not only about desires and pleasures.
On the contrary, Isidore says (Etym.) [*The words quoted do not occur in the work referred to; Cf. his De Summo Bono xxxvii, xlii, and De Different. ii, 39]: that "it is temperance whereby lust and desire are kept under control."
I answer that, As stated above (Q. 123, A. 12; Q. 136, A. 1), it belongs to moral virtue to safeguard the good of reason against the passions that rebel against reason. Now the movement of the soul's passions is twofold, as stated above (I-II, Q. 23, A. 2), when we were treating of the passions: the one, whereby the sensitive appetite pursues sensible and bodily goods, the other whereby it flies from sensible and bodily evils.
The first of these movements of the sensitive appetite rebels against reason chiefly by lack of moderation. Because sensible and bodily goods, considered in their species, are not in opposition to reason, but are subject to it as instruments which reason employs in order to attain its proper end: and that they are opposed to reason is owing to the fact that the sensitive appetite fails to tend towards them in accord with the mode of reason. Hence it belongs properly to moral virtue to moderate those passions which denote a pursuit of the good.
On the other hand, the movement of the sensitive appetite in flying from sensible evil is mostly in opposition to reason, not through being immoderate, but chiefly in respect of its flight: because, when a man flies from sensible and bodily evils, which sometimes accompany the good of reason, the result is that he flies from the good of reason. Hence it belongs to moral virtue to make man while flying from evil to remain firm in the good of reason.
