Every quality of the mind is denominated virtuous, which gives pleasure by the mere survey; as every quality, which produces pain, is call'd vicious. This pleasure and this pain may arise from four different sources. For we reap a pleasure from the view of a character, which is naturally fitted to be useful to others, or to the person himself, or which is agreeable to others, or to the person himself. One may, perhaps, be surpriz'd, that amidst all these interests and pleasures, we shou'd forget our own, which touch us so nearly on every other occasion. But we shall easily satisfy ourselves on this head, when we consider, that every particular person's pleasure and interest being different, 'tis impossible men cou'd ever agree in their sentiments and judgments, unless they chose some common point of view, from which they might survey their object, and which might cause it to appear the same to all of them. Now, in judging of characters, the only interest or pleasure, which appears the same to every spectator, is that of the person himself, whose character is examin'd; or that of persons, who have a connexion with him. And tho' such interests and pleasures touch us more faintly than our own, yet being more constant and universal, they counter-ballance the latter even in practice, and are alone admitted in speculation as the standard of virtue and morality. They alone produce that particular feeling or sentiment, on which moral distinctions depend.
As to the good or ill desert of virtue or vice, 'tis an evident consequence of the sentiments of pleasure or uneasiness. These sentiments produce love or hatred; and love or hatred, by the original constitution of human passion, is attended with benevolence or anger; that is, with a desire of making happy the person we love, and miserable the person we hate. We have treated of this more fully on another occasion.
