The collapse of virtue into a semblance is one consequence of the difficulties and instabilities that confound the moral virtues, tolerance among the rest, but there are others. Bernard Williams, for example, agrees that tolerant states of mind and affection are difficult to maintain. Endurance is not easily combined with dislike, to say nothing of hatred or repugnance, and he admits as much. At the same time, he recognizes that in certain circumstances dislike can be tempered, its impulse to action restrained.47 Fear of one’s own intolerance, its postures and consequences, can encourage self- control. So can hatred of the cruelty that intolerance can inflict on others. In either case, acts of toleration can result, but not from a tolerant state of mind, not from a tolerant collection of loves and desires. An impulse to act intolerantly is, after all, being restrained. In this way, Williams can ac-knowledge the self-consuming instabilities of tolerance the virtue, while endorsing acts of toleration produced by other than virtuous means. And of course, to say that acts of toleration are largely products of self-restraint is equivalent to saying that tolerance the virtue is irrelevant. As Aquinas reminds us, the virtuous exhibit what the self-restraining do not—a unity of internal state and external action. By habit they acquire both “an aptness to a good act” and “the right use of that aptness.” The just, for instance,are not only capable of giving to others the good they are due by right, but they are inclined to do so with a prompt will. They desire what is right with a settled habit, and their actions accord with their desires. Thus Aquinas can say that, in general, "a virtue is that which makes its possessor good?, insofar as it generates the right kinds of rational loves and desires, and in turn these loves and desires make “his work good likewise.”48
