But these are only the first foundations of the affections of pity and malice. Other passions are afterwards confounded with them. There is always a mixture of love or tenderness with pity, and of hatred or anger with malice. But it must be confessed, that this mixture seems at first sight to be contradictory to my system. For as pity is an uneasiness, and malice a joy, arising from the misery of others, pity should naturally, as in all other cases, produce hatred; and malice, love.

This contradiction I endeavour to reconcile, after the following manner.

In order to cause a transition of passions, there is required a double relation of impressions and ideas, nor is one relation sufficient to produce this effect. But that we may understand the full force of this double relation, we must consider, that it is not the present sensation alone or momentary pain or pleasure, which determines the character of any passion, but the whole bent or tendency of it from the beginning to the end. One impression may be related to another, not only when their sensations are resembling, as we have all along supposed in the preceding cases; but also when their impulses or directions are similar and correspondent. This cannot take place with regard to pride and humility; because these are only pure sensations, without any direction or tendency to action. We are, therefore, to look for instances of this peculiar relation of impressions only in such affections, as are attended with a certain appetite or desire; such as those of love and hatred.

Benevolence or the appetite, which attends love, is a desire of the happiness of the person beloved, and an aversion to his misery; as anger or the appetite, which attends hatred, is a desire of the misery of the person hated, and an aversion to his happiness. A desire, therefore, of the happiness of another, and aversion to his misery, are similar to benevolence; and a desire of his misery and aversion to his happiness are correspondent to anger. Now pity is a desire of happiness to another, and aversion to his misery; as malice is the contrary appetite. Pity, then, is related to benevolence; and malice to anger: And as benevolence has been already found to be connected with love, by a natural and original quality, and anger with hatred; it is by this chain the passions of pity and malice are connected with love and hatred.

This hypothesis is founded on sufficient experience. A man, who from any motives has entertained a resolution of performing an action, naturally runs into every other view or motive, which may fortify that resolution, and give it authority and influence on the mind. To confirm us in any design, we search for motives drawn from interest, from honour, from duty. What wonder, then, that pity and benevolence, malice, and anger, being the same desires arising from different principles, should so totally mix together as to be undistinguishable? As to the connexion betwixt benevolence and love, anger and hatred, being original and primary, it admits of no difficulty.

We may add to this another experiment, viz, that benevolence and anger, and consequently love and hatred, arise when our happiness or misery have any dependance on the happiness or misery of another person, without any farther relation. I doubt not but this experiment will appear so singular as to excuse us for stopping a moment to consider it.

Suppose, that two persons of the same trade should seek employment in a town, that is not able to maintain both, it is plain the success of one is perfectly incompatible with that of the other, and that whatever is for the interest of either is contrary to that of his rival, and so vice versa. Suppose again, that two merchants, though living in different parts of the world, should enter into co-partnership together, the advantage or loss of one becomes immediately the advantage or loss of his partner, and the same fortune necessarily attends both. Now it is evident, that in the first case, hatred always follows upon the contrariety of interests; as in the second, love arises from their union. Let us consider to what principle we can ascribe these passions.

It is plain they arise not from the double relations of impressions and ideas, if we regard only the present sensation. For takeing the first case of rivalship; though the pleasure and advantage of an antagonist necessarily causes my pain and loss, yet to counter-ballance this, his pain and loss causes my pleasure and advantage; and supposing him to be unsuccessful, I may by this means receive from him a superior degree of satisfaction. In the same manner the success of a partner rejoices me, but then his misfortunes afflict me in an equal proportion; and it is easy to imagine, that the latter sentiment may in many cases preponderate. But whether the fortune of a rival or partner be good or bad, I always hate the former and love the latter.

This love of a partner cannot proceed from the relation or connexion betwixt us; in the same manner as I love a brother or countryman. A rival has almost as close a relation to me as a partner. For as the pleasure of the latter causes my pleasure, and his pain my pain; so the pleasure of the former causes my pain, and his pain my pleasure. The connexion, then, of cause and effect is the same in both cases; and if in the one case, the cause and effect have a farther relation of resemblance, they have that of contrariety in the other; which, being also a species of resemblance, leaves the matter pretty equal.

The only explication, then, we can give of this phænomenon is derived from that principle of a parallel direction above-mentioned. Our concern for our own interest gives us a pleasure in the pleasure, and a pain in the pain of a partner, after the same manner as by sympathy we feel a sensation correspondent to those, which appear in any person, who is present with us. On the other hand, the same concern for our interest makes us feel a pain in the pleasure, and a pleasure in the pain of a rival; and in short the same contrariety of sentiments as arises from comparison and malice. Since, therefore, a parallel direction of the affections, proceeding from interest, can give rise to benevolence or anger, no wonder the same parallel direction, derived from sympathy and from comparison, should have the same effect.

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.
