Wherefore any virtue that is effective of moderation in some matter or other, and restrains the appetite in its impulse towards something, may be reckoned a part of temperance, as a virtue annexed thereto.

Context

“The potential parts of a principal virtue are called secondary virtues: for while the principal virtue observes the mode in some principal matter, these observe the mode in some other matter wherein moderation is not so difficult. Now it belongs to temperance to moderate pleasures of touch, which are most difficult to moderate. Wherefore any virtue that is effective of moderation in some matter or other, and restrains the appetite in its impulse towards something, may be reckoned a part of temperance, as a virtue annexed thereto. This happens in three ways: first, in the inward movements of the soul; secondly, in the outward movements and actions of the body; thirdly, in outward things. Now besides the movement of concupiscence, which temperance moderates and restrains, we find in the soul three movements towards a particular object.” source
