Persons of delicate fibres and a weak constitution of body complain, that in looking on the sores and ulcers which are exposed by beggars in the streets, they are apt to feel an itching or uneasy sensation in the correspondent part of their own bodies. The horror which they conceive at the misery of those wretches affects that particular part in themselves more than any other; because that horror arises from conceiving what they themselves would suffer, if they really were the wretches whom they are looking upon, and if that particular part in themselves was actually affected in the same miserable manner. The very force of this conception is sufficient, in their feeble frames, to produce that itching or uneasy sensation complained of. Men of the most robust make, observe that in looking upon sore eyes they often feel a very sensible soreness in their own, which proceeds from the same reason; that organ being in the strongest man more delicate, than any other part of the body is in the weakest.

Neither is it those circumstances only, which create pain or sorrow, that call forth our fellow-feeling. Whatever is the passion which arises from any object in the person principally concerned, an analogous emotion springs up, at the thought of his situation, in the breast of every attentive spectator.4 Our joy for the deliverance of those heroes of tragedy or romance who interest us, is as sincere as our grief for their distress, and our fellow-feeling with their misery is not more real than that with their happiness. We enter into their gratitude towards those faithful friends who did not desert them in their difficulties; and we heartily go along with their resentment against those perfidious5 traitors who injured, abandoned, or deceived them. In every passion of which the mind of man is susceptible, the emotions of the bystander always correspond to what, by bringing the case home to himself, he imagines should be the sentiments of the sufferer.

Pity and compassion are words appropriated to signify our fellow-feeling with the sorrow of others. Sympathy, though its meaning was, perhaps, originally the same, may now, however, without much impropriety, be made use of to denote our fellow-feeling with any passion whatever.6

Upon some occasions sympathy may seem to arise merely from the view of a certain emotion in another person. The passions, upon some occasions, may seem to be transfused from one man to another, instantaneously, and antecedent to any knowledge of what excited them in the person principally concerned. Grief and joy, for example, strongly expressed in the look and gestures of any one, at once affect the spectator with some degree of a like painful or agreeable emotion. A smiling face is, to every body that sees it, a cheerful object; as a sorrowful countenance, on the other hand, is a melancholy one.

This, however, does not hold universally, or with regard to every passion. There are some passions of which the expressions excite no sort of sympathy, but, before we are acquainted with what gave occasion to them, serve rather to disgust and provoke us against them. The furious behaviour of an angry man is more likely to exasperate us against himself than against his enemies. As we are unacquainted with his provocation, we cannot bring his case home to ourselves, nor conceive any thing like the passions which it excites. But we plainly see what is the situation of those with whom he is angry, and to what violence they may be exposed from so enraged an adversary. We readily, therefore, sympathize with their fear or resentment, and are immediately disposed to take part against the man from whom they appear to be in so much danger.

If the very appearances of grief and joy inspire us with some degree of the like emotions, it is because they suggest to us the general idea of some good or bad fortune that has befallen the person in whom we observe them: and in these passions this is sufficient to have some little influence upon us. The effects of grief and joy terminate in the person who feels those emotions, of which the expressions do not, like those of resentment, suggest to us the idea of any other person for whom we are concerned, and whose interests are opposite to his. The general idea of good or bad fortune, therefore, creates some concern for the person who has met with it, but the general idea of provocation excites no sympathy with the anger of the man who has received it. Nature, it seems, teaches us to be more averse to enter into this passion, and, till informed of its cause, to be disposed rather to take part against it.

Even our sympathy with the grief or joy of another, before we are informed of the cause of either, is always extremely imperfect. General lamentations, which express nothing but the anguish of the sufferer, create rather a curiosity to inquire into his situation, along with some disposition to sympathize with him, than any actual sympathy that is very sensible. The first question which we ask is, What has befallen you? Till this be answered, though we are uneasy both from the vague idea of his misfortune, and still more from torturing ourselves with conjectures about what it may be, yet our fellow-feeling is not very considerable.

Sympathy, therefore, does not arise so much from the view of the passion, as from that of the situation which excites it. We sometimes feel for another, a passion of which he himself seems to be altogether incapable; because, when we put ourselves in his case, that passion arises in our breast from the imagination, though it does not in his from the reality. We blush for the impudence and rudeness of another, though he himself appears to have no sense of the impropriety of his own behaviour; because we cannot help feeling with what confusion we ourselves should be covered, had we behaved in so absurd a manner.

Of all the calamities to which the condition of mortality exposes mankind, the loss of reason appears, to those who have the least spark of humanity, by far the most dreadful, and they behold that last stage of human wretchedness with deeper commiseration than any other. But the poor wretch, who is in it, laughs and sings, perhaps, and is altogether insensible of his own misery. The anguish which humanity feels, therefore, at the sight of such an object, cannot be the reflection of any sentiment of the sufferer. The compassion of the spectator must arise altogether from the consideration of what he himself would feel if he was reduced to the same unhappy situation, and, what perhaps is impossible, was at the same time able to regard it with his present reason and judgment.

What are the pangs of a mother, when she hears the moanings of her infant that, during the agony of disease cannot express what it feels? In her idea of what it suffers, she joins, to its real helplessness, her own consciousness of that helplessness, and her own terrors for the unknown consequences of its disorder; and out of all these, forms, for her own sorrow, the most complete image of misery and distress. The infant, however, feels only the uneasiness of the present instant, which can never be great. With regard to the future, it is perfectly secure, and in its thoughtlessness and want of foresight, possesses an antidote against fear and anxiety, the great tormentors of the human breast, from which reason and philosophy will, in vain, attempt to defend it, when it grows up to a man.

We sympathize even with the dead, and overlooking what is of real importance in their situation, that awful futurity which awaits them, we are chiefly affected by those circumstances which strike our senses, but can have no influence upon their happiness. It is miserable, we think, to be deprived of the light of the sun; to be shut out from life and conversation; to be laid in the cold grave, a prey to corruption and the reptiles of the earth; to be no more thought of in this world, but to be obliterated, in a little time, from the affections, and almost from the memory, of their dearest friends and relations. Surely, we imagine, we can never feel too much for those who have suffered so dreadful a calamity.
