SYMPATHY also denotes the quality of being affected by the affection of another; and may subsist either between different persons or bodies, or between different parts of the same body. It is either similar or dissimilar: similar, when the affection or action in the sympathiser is similar to the affection or action in the sympathant; and dissimilar, when those are different.—Sympathy, too, is often an imitative faculty, sometimes involuntary, frequently without consciousness: thus we yawn when we see others yawn, and are made to laugh by the laughing of another.
