...As nature teaches the spectators to assume the circumstances of the person principally concerned, so she teaches this last in some measure to assume those of the spectators. As they are continually placing themselves in his situation, and thence conceiving emotions similar to what he feels; so he is as constantly placing himself in theirs, and thence conceiving some degree of that coolness about his own fortune, with which he is sensible that they will view it. As they are constantly considering what they themselves would feel, if they actually were the sufferers, so he is constantly led to imagine in what manner he would be affected if he was only one of the spectators of his own situation. As their sympathy makes them look at it in some measure with his eyes, so his sympathy makes him look at it, in some measure, with theirs, especially when in their presence, and acting under their observation: and, as the reflected passion which he thus conceives is much weaker than the original one, it necessarily abates the violence of what he felt before he came into their presence, before he began to recollect in what manner they would be affected by it, and to view his situation in this candid and impartial light.
The mind, therefore, is rarely so disturbed, but that the company of a friend will restore it to some degree of tranquility and sedateness. The breast is, in some measure, calmed and composed the moment we come into his presence. We are immediately put in mind of the light in which he will view our situation, and we begin to view it ourselves in the same light; for the effect of sympathy is instantaneous. We expect less sympathy from a common acquaintance than from a friend; we cannot open to the former all those little circumstances which we can unfold to the latter; we assume, therefore, more tranquility before him, and endeavour to fix our thoughts upon those general outlines of our situation which he is willing to consider. We expect still less sympathy from an assembly of strangers, and we assume, therefore, still more tranquility before them, and always endeavour to bring down our passion to that pitch, which the particular company we are in may be expected to go along with. Nor is this only an assumed appearance; for if we are at all masters of ourselves, the presence of a mere acquaintance will really compose us, still more than that of a friend; and that of an assembly of strangers, still more than that of an acquaintance.
Society and conversation, therefore, are the most powerful remedies for restoring the mind to its tranquility, if, at any time, it has unfortunately lost it; as well as the best preservatives of that equal and happy temper, which is so necessary to self-satisfaction and enjoyment. Men of retirement and speculation, who are apt to sit brooding at home over either grief or resentment, though they may often have more humanity, more generosity, and a nicer sense of honour, yet seldom possess that equality of temper which is so common among men of the world.
-Adam Smith, Theory of Moral Sentiments
