Context

“Hence human virtue is that which inclines man to something in accordance with reason. Now temperance evidently inclines man to this, since its very name implies moderation or temperateness, which reason causes. Therefore temperance is a virtue. Reply Obj. 1: Nature inclines everything to whatever is becoming to it. Wherefore man naturally desires pleasures that are becoming to him. Since, however, man as such is a rational being, it follows that those pleasures are becoming to man which are in accordance with reason. From such pleasures temperance does not withdraw him, but from those which are contrary to reason.” source
