Is toleration’s patient endurance like theft? Does its moral substance come packaged with the act itself? No, but then, most acts are nothing like this. Most are like “taking what another has” or “walking across a field,” where the moral species of the act remains undefined even as its object is known. We might know, in general terms, what was done and yet remain uncertain about its moral substance until we situate the act in its circumstances and take note of the end that it has been chosen to achieve {ST MI. 18.9.1; 20.1). Apart from these findings, we won’t know whether the act was good or evil? just or unjust. In Aquinas^ language, it will remain in its natural species {ST I-II. 1.3.3), and an act of patient endurance is like this. If we assume that it was chosen for the sake of a tolerant end—for the social peace that is shared with the tolerated and mutual autonomy with respect to the difference in dispute—then it will be the circumstances, the who, what, where, and how of the act, that determine its moral substance.So then, suppose someone objects to something about another, something said or done or embodied in the others life, and suppose she responds with toleration’s act, its patient endurance. Is this act good and this good due this person? Is this an act of true tolerance? Well, it depends on a couple of things. First, is the difference in dispute in fact objectionable, or at the very least, does the person who finds it so have good reason to think that it is. Some differences are in fact objectionable, some are not, and some are thought to be so even when they are not.
