Sympathy, however, cannot, in any sense, be regarded as a selfish principle. When I sympathize with your sorrow or your indignation, it may be pretended, indeed, that my emotion is founded in self-love, because it arises from bringing your case home to myself, from putting myself in your situation, and thence conceiving what I should feel in the like circumstances. But though sympathy is very properly said to arise from an imaginary change of situations with the person principally concerned, yet this imaginary change is not supposed to happen to me in my own person and character, but in that of the person with whom I sympathize. When I condole with you for the loss of your only son, in order to enter into your grief, I do not consider what I, a person of such a character and profession, should suffer, if I had a son, and if that son was unfortunately to die: but I consider what I should suffer if I was really you, and I not only change circumstances with you, but I change persons and characters. My grief, therefore, is entirely upon your account, and not in the least upon my own. It is not, therefore, in the least selfish. How can that be regarded as a selfish passion, which does not arise even from the imagination of any thing that has befallen, or that relates to myself, in my own proper person and character, but which is entirely occupied about what relates to you? A man may sympathize with a woman in child-bed; though it is impossible that he should conceive himself as suffering her pains in his own proper person and character. That whole account of human nature, however, which deduces all sentiments and affections from self-love, which has made so much noise in the world, but which, so far as I know, has never yet been fully and distinctly explained, seems to me to have arisen from some confused misapprehension of the system of sympathy.
