In general we may observe, that it is impossible to do good to others, from whatever motive, without feeling some touches of kindness and good-will towards them; as the injuries we do, not only cause hatred in the person, who suffers them, but even in ourselves. These phaenomena, indeed, may in part be accounted for from other principles.

But here there occurs a considerable objection, which it will be necessary to examine before we proceed any farther. I have endeavoured to prove, that power and riches, or poverty and meanness; which give rise to love or hatred, without producing any original pleasure or uneasiness; operate upon us by means of a secondary sensation derived from a sympathy with that pain or satisfaction, which they produce in the person, who possesses them. From a sympathy with his pleasure there arises love; from that with his uneasiness, hatred. But it is a maxim, which I have just now established, and which is absolutely necessary to the explication of the phaenomena of pity and malice, that it is not the present sensation or momentary pain or pleasure, which determines the character of any passion, but the general bent or tendency of it from the beginning to the end. For this reason, pity or a sympathy with pain produces love, and that because it interests us in the fortunes of others, good or bad, and gives us a secondary sensation correspondent to the primary; in which it has the same influence with love and benevolence. Since then this rule holds good in one case, why does it not prevail throughout, and why does sympathy in uneasiness ever produce any passion beside good-will and kindness? Is it becoming a philosopher to alter his method of reasoning, and run from one principle to its contrary, according to the particular phænomenon, which he would explain?

I have mentioned two different causes, from which a transition of passion may arise, viz, a double relation of ideas and impressions, and what is similar to it, a conformity in the tendency and direction of any two desires, which arise from different principles. Now I assert, that when a sympathy with uneasiness is weak, it produces hatred or contempt by the former cause; when strong, it produces love or tenderness by the latter. This is the solution of the foregoing difficulty, which seems so urgent; and this is a principle founded on such evident arguments, that we ought to have established it, even though it were not necessary to the explication of any phænomenon.

It is certain, that sympathy is not always limited to the present moment, but that we often feel by communication the pains and pleasures of others, which are not in being, and which we only anticipate by the force of imagination. For supposing I saw a person perfectly unknown to me, who, while asleep in the fields, was in danger of being trod under foot by horses, I should immediately run to his assistance; and in this I should be actuated by the same principle of sympathy, which makes me concerned for the present sorrows of a stranger. The bare mention of this is sufficient. Sympathy being nothing but a lively idea converted into an impression, it is evident, that, in considering the future possible or probable condition of any person, we may enter into it with so vivid a conception as to make it our own concern; and by that means be sensible of pains and pleasures, which neither belong to ourselves, nor at the present instant have any real existence.

But however we may look forward to the future in sympathizing with any person, the extending of our sympathy depends in a great measure upon our sense of his present condition. It is a great effort of imagination, to form such lively ideas even of the present sentiments of others as to feel these very sentiments; but it is impossible we could extend this sympathy to the future, without being aided by some circumstance in the present, which strikes upon us in a lively manner. When the present misery of another has any strong influence upon me, the vivacity of the conception is not confined merely to its immediate object, but diffuses its influence over all the related ideas, and gives me a lively notion of all the circumstances of that person, whether past, present, or future; possible, probable or certain. By means of this lively notion I am interested in them; take part with them; and feel a sympathetic motion in my breast, conformable to whatever I imagine in his. If I diminish the vivacity of the first conception, I diminish that of the related ideas; as pipes can convey no more water than what arises at the fountain. By this diminution I destroy the future prospect, which is necessary to interest me perfectly in the fortune of another. I may feel the present impression, but carry my sympathy no farther, and never transfuse the force of the first conception into my ideas of the related objects. If it be another's misery, which is presented in this feeble manner, I receive it by communication, and am affected with all the passions related to it: But as I am not so much interested as to concern myself in his good fortune, as well as his bad, I never feel the extensive sympathy, nor the passions related to it.

Now in order to know what passions are related to these different kinds of sympathy, we must consider, that benevolence is an original pleasure arising from the pleasure of the person beloved, and a pain proceeding from his pain: From which correspondence of impressions there arises a subsequent desire of his pleasure, and aversion to his pain. In order, then, to make a passion run parallel with benevolence, it is requisite we should feel these double impressions, correspondent to those of the person, whom we consider; nor is any one of them alone sufficient for that purpose. When we sympathize only with one impression, and that a painful one, this sympathy is related to anger and to hatred, upon account of the uneasiness it conveys to us. But as the extensive or limited sympathy depends upon the force of the first sympathy; it follows, that the passion of love or hatred depends upon the same principle. A strong impression, when communicated, gives a double tendency of the passions; which is related to benevolence and love by a similarity of direction; however painful the first impression might have been. A weak impression, that is painful, is related to anger and hatred by the resemblance of sensations. Benevolence, therefore, arises from a great degree of misery, or any degree strongly sympathized with: Hatred or contempt from a small degree, or one weakly sympathized with; which is the principle I intended to prove and explain.

Nor have we only our reason to trust to for this principle, but also experience. A certain degree of poverty produces contempt; but a degree beyond causes compassion and good-will. We may under-value a peasant or servant; but when the misery of a beggar appears very great, or is painted in very lively colours, we sympathize with him in his afflictions; and feel in our heart evident touches of pity and benevolence. The same object causes contrary passions according to its different degrees. The passions, therefore, must depend upon principles, that operate in such certain degrees, according to my hypothesis. The encrease of the sympathy has evidently the same effect as the encrease of the misery.

A barren or desolate country always seems ugly and disagreeable, and commonly inspires us with contempt for the inhabitants. This deformity, however, proceeds in a great measure from a sympathy with the inhabitants, as has been already observed; but it is only a weak one, and reaches no farther than the immediate sensation, which is disagreeable. The view of a city in ashes conveys benevolent sentiments; because we there enter so deep into the interests of the miserable inhabitants, as to wish for their prosperity, as well as feel their adversity.

But though the force of the impression generally produces pity and benevolence, it is certain, that by being carryed too far it ceases to have that effect. This, perhaps, may be worth our notice. When the uneasiness is either small in itself, or remote from us, it engages not the imagination, nor is able to convey an equal concern for the future and contingent good, as for the present and real evil Upon its acquiring greater force, we become so interested in the concerns of the person, as to be sensible both of his good and had fortune; and from that compleat sympathy there arises pity and benevolence. But it will easily be imagined, that where the present evil strikes with more than ordinary force, it may entirely engage our attention, and prevent that double sympathy, above-mentioned. Thus we find, that though every one, but especially women, are apt to contract a kindness for criminals, who go to the scaffold, and readily imagine them to be uncommonly handsome and wellshaped; yet one, who is present at the cruel execution of the rack, feels no such tender emotions; but is in a manner overcome with horror, and has no leisure to temper this uneasy sensation by any opposite sympathy.

But the instance, which makes the most clearly for my hypothesis, is that wherein by a change of the objects we separate the double sympathy even from a midling degree of the passion; in which case we find, that pity, instead of producing love and tenderness as usual, always gives rise to the contrary affection. When we observe a person in misfortunes, we are affected with pity and love; but the author of that misfortune becomes the object of our strongest hatred, and is the more detested in proportion to the degree of our compassion. Now for what reason should the same passion of pity produce love to the person, who suffers the misfortune, and hatred to the person, who causes it; unless it be because in the latter case the author bears a relation only to the misfortune; whereas in considering the sufferer we carry our view on every side, and wish for his prosperity, as well as are sensible of his affliction?
