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. 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 chearful 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 behavior 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.
