_Secondly_, Our sense or discernment of actions as morally good or evil, implies in it a sense or discernment of them as of good or ill desert. It may be difficult to explain this perception, so as to answer all the questions which may be asked concerning it: but every one speaks of such and such actions as deserving punishment; and it is not, I suppose, pretended, that they have absolutely no meaning at all to the expression. Now the meaning plainly is not, that we conceive it for the good of society, that the doer of such actions should be made to suffer. For if, unhappily, it were resolved, that a man, who by some innocent action, was infected with the plague, should be left to perish, lest, by other people’s coming near him, the infection should spread; no one would say he _deserved_ this treatment. Innocence and ill desert are inconsistent ideas. Ill desert always supposes guilt: and if one be no part of the other, yet they are evidently and naturally connected in our mind. The sight of a man in misery raises our compassion towards him; and if this misery be inflicted on him by another, our indignation against the author of it. But when we are informed, that the sufferer is a villain, and is punished only for his treachery or cruelty; our compassion exceedingly lessens, and in many instances our indignation wholly subsides. Now what produces this effect is the conception of that in the sufferer, which we call ill desert. Upon considering then, or viewing together, our notion of vice and that of misery, there results a third, that of ill desert. And thus there is in human creatures an association of the two ideas, natural and moral evil, wickedness and punishment. If this association were merely artificial or accidental, it were nothing: but being most unquestionably natural, it greatly concerns us to attend to it, instead of endeavoring to explain it away. It may be observed further, concerning our perception of good and of ill desert, that the former is very weak with respect to common instances of virtue. One reason of which may be, that it does not appear to a spectator, how far such instances of virtue proceed from a virtuous principle, or in what degree this principle is prevalent: since a very weak regard to virtue may be sufficient to make men act well in many common instances. On the other hand, our perception of ill desert in vicious actions lessens, in proportion to the temptations men are thought to have had to such vices. For, vice in human creatures consisting chiefly in the absence or want of the virtuous principle; though a man be overcome, suppose by tortures, it does not from thence appear to what degree the virtuous principle was wanting. All that appears is, that he had it not in such a degree, as to prevail over the temptation; but possibly he had it in a degree, which would have rendered him proof against common temptations.
