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. SECTION II. OF GREATNESS OF MIND. It may now be proper to illustrate this general system of morals, by applying it to particular instances of virtue and vice, and showing how their merit or demerit arises from the four sources here explained. We shall begin with examining the passions of _pride_ and _humility_, and shall consider the vice or virtue that lies in their excesses or just proportion. An excessive pride or overweening conceit of ourselves, is always esteemed vicious, and is universally hated, as modesty, or a just sense of our weakness, is esteemed virtuous, and procures the good will of every one. Of the four sources of moral distinctions, this is to be ascribed to the _third_; viz. the immediate agreeableness and disagreeableness of a quality to others, without any reflections on the tendency of that quality. In order to prove this, we must have recourse to two principles, which are very conspicuous in human nature. The _first_ of these is the _sympathy_ and communication of sentiments and passions above mentioned. So close and intimate is the correspondence of human souls, that no sooner any person approaches me, than he diffuses on me all his opinions, and draws along my judgment in a greater or lesser degree. And though, on many occasions, my sympathy with him goes not so far as entirely to change my sentiments and way of thinking, yet it seldom is so weak as not to disturb the easy course of my thought, and give an authority to that opinion which is recommended to me by his assent and approbation. Nor is it any way material upon what subject he and I employ our thoughts. Whether we judge of an indifferent person, or of my own character, my sympathy gives equal force to his decision: and even his sentiments of his own merit make me consider him in the same light in which he regards himself.
