all mankind, consists in a natural relish of the beauty of virtue, and
words, it seems to us no other than just, that as they love us and do us good, we also should love them and do them good. And so it seems just, that when others' hearts oppose us, and they from their hearts do us hurt, our hearts should oppose them, and that we should desire themselves may suffer in like manner as we have suffered, i. e. there appears to us to be a natural agreement, proportion, and adjustment between these things; which is indeed a kind of moral sense, or sense of beauty in moral things. But, as was before shown, it is a moral sense of a secondary kind, and is entirely different from a sense or relish of the original essential beauty of true virtue; and may be without any principle of true virtue in the heart. Therefore, doubtless, it is a great mistake in any to suppose, that the moral sense which appears and is exercised in a sense of desert, is the same thing as a love of virtue, or a disposition and determination of mind to be pleased with true virtuous beauty, consisting in public benevolence. Which may be further confirmed, if it be considered, that even with respect to a sense of justice or desert, consisting in uniformity, and agreement between others' actions, towards us, and our actions towards them, in a way of well-doing, or of ill-doing, it is not absolutely necessary to the being of these passions of gratitude and anger, that there should be any notion of justice in them, in any public or general view of things: as will appear by what shall be next observed.
4. Those authors who hold, that the moral sense, which is natural to all mankind, consists in a natural relish of the beauty of virtue, and so arises from a principle of true virtue implanted by nature in the hearts of all, hold that true virtue consists in public benevolence. Therefore, if the affections of gratitude and anger necessarily imply such a moral sense as they suppose, then these affections imply some delight in the public good, and an aversion of the mind to public evil. And if so, then every time a man feels anger for opposition, or gratitude for any favour, there must be at least a supposition of a tendency to public injury in that opposition, and a tendency to public benefit in the favour that excites his gratitude. But how far is this from being true! For instance; a ship's crew enter into a conspiracy
