Our sense of beauty depends very much on this principle; and where any object has a tendency to produce pleasure in its possessor, it is always regarded as beautiful; as every object that has a tendency to produce pain, is disagreeable and deformed. Thus, the conveniency of a house, the fertility of a field, the strength of a horse, the capacity, security, and swift-sailing of a vessel, form the principal beauty of these several objects. Here the object, which is denominated beautiful, pleases only by its tendency to produce a certain effect. That effect is the pleasure or advantage of some other person. Now, the pleasure of a stranger for whom we have no friendship, pleases us only by sympathy. To this principle, therefore, is owing the beauty which we find in every thing that is useful. How considerable a part this is of beauty will easily appear upon reflection. Wherever an object has a tendency to produce pleasure in the possessor, or, in other words, is the proper cause of pleasure, it is sure to please the spectator, by a delicate sympathy with the possessor. Most of the works of art are esteemed beautiful, in proportion to their fitness for the use of man; and even many of the productions of nature derive their beauty from that source. Handsome and beautiful, on most occasions, is not an absolute, but a relative quality, and pleases us by nothing but its tendency to produce an end that is agreeable.[1]
The same principle produces, in many instances, our sentiments of morals, as well as those of beauty. No virtue is more esteemed than justice, and no vice more detested than injustice; nor are there any qualities which go farther to the fixing the character, either as amiable or odious. Now justice is a moral virtue, merely because it has that tendency to the good of mankind, and indeed is nothing but an artificial invention to that purpose. The same may be said of allegiance, of the laws of nations, of modesty, and of good manners. All these are mere human contrivances for the interest of society. And since there is a very strong sentiment of morals, which in all nations and all ages has attended them, we must allow that the reflecting on the tendency of characters and mental qualities is sufficient to give us the sentiments of approbation and blame. Now, as the means to an end can only be agreeable where the end is agreeable, and as the good of society, where our own interest is not concerned, or that of our friends, pleases only by sympathy, it follows, that sympathy is the source of the esteem which we pay to all the artificial virtues.
Thus it appears, that sympathy is a very powerful principle in human nature, that it has a great influence on our taste of beauty, and that it produces our sentiment of morals in all the artificial virtues. From thence we may presume, that it also gives rise to many of the other virtues, and that qualities acquire our approbation because of their tendency to the good of mankind. This presumption must become a certainty, when we find that most of those qualities which we naturally approve of, have actually that tendency, and render a man a proper member of society; while the qualities which we naturally disapprove of have a contrary tendency, and render any intercourse with the person dangerous or disagreeable. For having found, that such tendencies have force enough to produce the strongest sentiment of morals, we can never reasonably, in these cases, look for any other cause of approbation or blame; it being an inviolable maxim in philosophy, that where any particular cause is sufficient for an effect, we ought to rest satisfied with it, and ought not to multiply causes without necessity. We have happily attained experiments in the artificial virtues, where the tendency of qualities to the good of society is the sole cause of our approbation, without any suspicion of the concurrence of another principle. From thence we learn the force of that principle. And where that principle may take place, and the quality approved of is really beneficial to society, a true philosopher will never require any other principle to account for the strongest approbation and esteem.
That many of the natural virtues have this tendency to the good of society, no one can doubt of. Meekness, beneficence, charity, generosity, clemency, moderation, equity, bear the greatest figure among the moral qualities, and are commonly denominated the social virtues, to mark their tendency to the good of society. This goes so far, that some philosophers have represented all moral distinctions as the effect of artifice and education, when skilful politicians endeavoured to restrain the turbulent passions of men, and make them operate to the public good, by the notions of honour and shame. This system, however, is not consistent with experience. For, first, There are other virtues and vices beside those which have this tendency to the public advantage and loss. Secondly, Had not men a natural sentiment of approbation and blame, it could never be excited by politicians, nor would the words laudable and praiseworthy, blameable and odious, be any more intelligible than if they were a language perfectly unknown to us, as we have already observed. But though this system be erroneous, it may teach us that moral distinctions arise in a great measure from the tendency of qualities and characters to the interests of society, and that 'tis our concern for that interest which makes us approve or disapprove of them. Now, we have no such extensive concern for society, but from sympathy; and consequently 'tis that principle which takes us so far out of ourselves as to give us the same pleasure or uneasiness in the characters of others, as if they had a tendency to our own advantage or loss.
The only difference betwixt the natural virtues and justice lies in this, that the good which results from the former arises from every single act, and is the object of some natural passion; whereas a single act of justice, considered in itself, may often be contrary to the public good; and 'tis only the concurrence of mankind, in a general scheme or system of action, which is advantageous. When I relieve persons in distress, my natural humanity is my motive; and so far as my succour extends, so far have I promoted the happiness of my fellow-creatures. But if we examine all the questions that come before any tribunal of justice, we shall find that, considering each case apart, it would as often be an instance of humanity to decide contrary to the laws of justice as conformable to them. Judges take from a poor man to give to a rich; they bestow on the dissolute the labour of the industrious; and put into the hands of the vicious the means of harming both themselves and others. The whole scheme, however, of law and justice is advantageous to the society; and 'twas with a view to this advantage that men, by their voluntary conventions, established it. After it is once established by these conventions, it is naturally attended with a strong sentiment of morals, which can proceed from nothing but our sympathy with the interests of society. We need no other explication of that esteem which attends such of the natural virtues as have a tendency to the public good.
I must farther add, that there are several circumstances which render this hypothesis much more probable with regard to the natural than the artificial virtues. 'Tis certain, that the imagination is more affected by what is particular, than by what is general; and that the sentiments are always moved with difficulty, where their objects are in any degree loose and undetermined. Now, every particular act of justice is not beneficial to society, but the whole scheme or system; and it may not perhaps be any individual person for whom we are concerned, who receives benefit from justice, but the whole society alike. On the contrary, every particular act of generosity, or relief of the industrious and indigent, is beneficial, and is beneficial to a particular person, who is not undeserving of it. 'Tis more natural, therefore, to think that the tendencies of the latter virtue will affect our sentiments, and command our approbation, than those of the former; and therefore, since we find that the approbation of the former arises from their tendencies, we may ascribe, with better reason, the same cause to the approbation of the latter. In any number of similar effects, if a cause can be discovered for one, we ought to extend that cause to all the other effects which can be accounted for by it; but much more, if these other effects be attended with peculiar circumstances, which facilitate the operation of that cause.
Before I proceed farther, I must observe two remarkable circumstances in this affair, which may seem objections to the present system. The first may be thus explained. When any quality or character has a tendency to the good of mankind, we are pleased with it, and approve of it, because it presents the lively idea of pleasure; which idea affects us by sympathy, and is itself a kind of pleasure. But as this sympathy is very variable, it may be thought that our sentiments of morals must admit of all the same variations. We sympathize more with persons contiguous to us, than with persons remote from us; with our acquaintance, than with strangers; with our countrymen, than with foreigners. But notwithstanding this variation of our sympathy, we give the same approbation to the same moral qualities in China as in England. They appear equally virtuous, and recommend themselves equally to the esteem of a judicious spectator. The sympathy varies without a variation in our esteem. Our esteem, therefore, proceeds not from sympathy.
To this I answer, the approbation of moral qualities most certainly is not derived from reason, or any comparison of ideas; but proceeds entirely from a moral taste, and from certain sentiments of pleasure or disgust, which arise upon the contemplation and view of particular qualities or characters. Now, 'tis evident that those sentiments, whencever they are derived, must vary according to the distance or contiguity of the objects; nor can I feel the same lively pleasure from the virtues of a person who lived in Greece two thousand years ago, that I feel from the virtues of a familiar friend and acquaintance. Yet I do not say that I esteem the one more than the other; and therefore, if the variation of the sentiment, without a variation of the esteem, be an objection, it must have equal force against every other system, as against that of sympathy. But to consider the matter aright, it has no force at all; and 'tis the easiest matter in the world to account for it. Our situation with regard both to persons and things is in continual fluctuation; and a man that lies at a distance from us, may in a little time become a familiar acquaintance. Besides, every particular man has a peculiar position with regard to others; and 'tis impossible we could ever converse together on any reasonable terms, were each of us to consider characters and persons only as they appear from his peculiar point of view. In order, therefore, to prevent those continual contradictions, and arrive at a more stable judgment of things, we fix on some steady and general points of view, and always, in our thoughts, place ourselves in them, whatever may be our present situation. In like manner, external beauty is determined merely by pleasure; and 'tis evident a beautiful countenance cannot give so much pleasure, when seen at a distance of twenty paces, as when it is brought nearer us. We say not, however, that it appears to us less beautiful; because we know what effect it will have in such a position, and by that reflection we correct its momentary appearance.
In general, all sentiments of blame or praise are variable, according to our situation of nearness or remoteness with regard to the person blamed or praised, and according to the present disposition of our mind. But these variations we regard not in our general decisions, but still apply the terms expressive of our liking or dislike, in the same manner as if we remained in one point of view. Experience soon teaches us this method of correcting our sentiments, or at least of correcting our language, where the sentiments are more stubborn and unalterable. Our servant, if diligent and faithful, may excite stronger sentiments of love and kindness than Marcus Brutus, as represented in history; but we say not, upon that account, that the former character is more laudable than the latter. We know that, were we to approach equally near to that renowned patriot, he would command a much higher degree of affection and admiration. Such corrections are common with regard to all the senses; and indeed 'twere impossible we could ever make use of language, or communicate our sentiments to one another, did we not correct the momentary appearances of things, and overlook our present situation.
