It is very happy, in our philosophical researches, when we find the same phænomenon diversified by a variety of circumstances; and by discovering what is common among them, can the better assure ourselves of the truth of any hypothesis we may make use of to explain it. Were nothing esteemed virtue but what were beneficial to society, I am persuaded, that the foregoing explication of the moral sense ought still to be received, and that upon sufficient evidence: But this evidence must grow upon us, when we find other kinds of virtue, which will not admit of any explication except from that hypothesis. Here is a man, who is not remarkably defective in his social qualities; but what principally recommends him is his dexterity in business, by which he has extricated himself from the greatest difficulties, and conducted the most delicate affairs with a singular address and prudence. I find an esteem for him immediately to arise in me: His company is a satisfaction to me; and before I have any farther acquaintance with him, I would rather do him a service than another, whose character is in every other respect equal, but is deficient in that particular. In this case, the qualities that please me are all considered as useful to the person, and as having a tendency to promote his interest and satisfaction.

They are only regarded as means to an end, and please me in proportion to their fitness for that end. The end, therefore, must be agreeable to me. But what makes the end agreeable? The person is a stranger: I am no way interested in him, nor lie under any obligation to him: His happiness concerns not me, farther than the happiness of every human, and indeed of every sensible creature: That is, it affects me only by sympathy. From that principle, whenever I discover his happiness and good, whether in its causes or effects, I enter so deeply into it, that it gives me a sensible emotion.

The appearance of qualities, that have a tendency to promote it, have an agreeable effect upon my imagination, and command my love and esteem.

This theory may serve to explain, why the same qualities, in all cases, produce both pride and love, humility and hatred; and the same man is always virtuous or vicious, accomplished or despicable to others, who is so to himself. A person, in whom we discover any passion or habit, which originally is only incommodious to himself, becomes always disagreeable to us, merely on its account; as on the other hand, one whose character is only dangerous and disagreeable to others, can never be satisfied with himself, as long as he is sensible of that disadvantage. Nor is this observable only with regard to characters and manners, but may be remarked even in the most minute circumstances. A violent cough in another gives us uneasiness; though in itself it does not in the least affect us. A man will be mortified, if you tell him he has a stinking breath; though it is evidently no annoyance to himself.

Our fancy easily changes its situation; and either surveying ourselves as we appear to others, or considering others as they feel themselves, we enter, by that means, into sentiments, which no way belong to us, and in which nothing but sympathy is able to interest us. And this sympathy we sometimes carry so far, as even to be displeased with a quality commodious to us, merely because it displeases others, and makes us disagreeable in their eyes; though perhaps we never can have any interest in rendering ourselves agreeable to them.

There have been many systems of morality advanced by philosophers in all ages; but if they are strictly examined, they may be reduced to two, which alone merit our attention. Moral good and evil are certainly distinguished by our sentiments, not by reason: But these sentiments may arise either from the mere species or appearance of characters and passions, or from reflections on their tendency to the happiness of mankind, and of particular persons. My opinion is, that both these causes are intermixed in our judgments of morals; after the same manner as they are in our decisions concerning most kinds of external beauty: Though I am also of opinion, that reflections on the tendencies of actions have by far the greatest influence, and determine all the great lines of our duty. There are, however, instances, in cases of less moment, wherein this immediate taste or sentiment produces our approbation. Wit, and a certain easy and disengaged behaviour, are qualities immediately agreeable to others, and command their love and esteem.

Some of these qualities produce satisfaction in others by particular original principles of human nature, which cannot be accounted for: Others may be resolved into principles, which are more general. This will best appear upon a particular enquiry.

As some qualities acquire their merit from their being immediately agreeable to others, without any tendency to public interest; so some are denominated virtuous from their being immediately agreeable to the person himself, who possesses them. Each of the passions and operations of the mind has a particular feeling, which must be either agreeable or disagreeable. The first is virtuous, the second vicious. This particular feeling constitutes the very nature of the passion; and therefore needs not be accounted for.

But however directly the distinction of vice and virtue may seem to flow from the immediate pleasure or uneasiness, which particular qualities cause to ourselves or others; it is easy to observe, that it has also a considerable dependence on the principle of sympathy so often insisted on. We approve of a person, who is possessed of qualities immediately agreeable to those, with whom he has any commerce; though perhaps we ourselves never reaped any pleasure from them. We also approve of one, who is possessed of qualities, that are immediately agreeable to himself; though they be of no service to any mortal. To account for this we must have recourse to the foregoing principles.

Thus, to take a general review of the present hypothesis: Every quality of the mind is denominated virtuous, which gives pleasure by the mere survey; as every quality, which produces pain, is called 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 surprized. that amidst all these interests and pleasures, we should 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, it is impossible men could 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 examined; or that of persons, who have a connexion with him. And though 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, it is 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.

It may now be proper to illustrate this general system of morals, by applying it to particular instances of virtue and vice, and shewing 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 overweaning 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.

This principle of sympathy is of so powerful and insinuating a nature, that it enters into most of our sentiments and passions, and often takes place under the appearance of its contrary. For it is remarkable, that when a person opposes me in any thing, which I am strongly bent upon, and rouzes up my passion by contradiction, I have always a degree of sympathy with him, nor does my commotion proceed from any other origin. We may here observe an evident conflict or rencounter of opposite principles and passions. On the one side there is that passion or sentiment, which is natural to me; and it is observable, that the stronger this passion is, the greater is the commotion. There must also be some passion or sentiment on the other side; and this passion can proceed from nothing but sympathy.

The sentiments of others can never affect us, but by becoming, in some measure, our own; in which case they operate upon us, by opposing and encreasing our passions, in the very same manner, as if they had been originally derived from our own temper and disposition. While they remain concealed in the minds of others, they can never have an influence upon us: And even when they are known, if they went no farther than the imagination, or conception; that faculty is so accustomed to objects of every different kind, that a mere idea, though contrary to our sentiments and inclinations, would never alone be able to affect us.
