It is a familiar remark that we find something not altogether disagreeable in hearing of the misfortunes of even our best friends. From the standpoint of social science it is evident that humanity is not entirely dominated by the social and sympathetic instincts since even when these are most strongly manifested there is always a remnant of the fighting impulse in ambush, which greets with joy any damage to a friend as to a foe. This is the principle of competition. We know that untutored savages make violent demonstrations of joy over the misfortunes of an enemy, their fiendish laugh of triumph has been often described, and childhood recollections furnish most of us with striking data in the same line. “A ten-year-old boy who had daubed a comrade with filthy mud from the street danced around his victim and screamed with laughter.”[480] Sometimes scornful and contemptuous laughter serves as a weapon, for it is not always a mere expression of feeling, being frequently used to infuriate an opponent much as a provoking manner is employed. We find, too, that in numerous cases it originates in a triumphant feeling, as when the teasing we have been considering is successful, and also when spectators applaud such success. Then, too, there is laughter at the artistic representation of such scenes, pictorial, plastic, and poetic. Yet we are far from exhausting the list. As a result of the struggle for life, every inferiority calls forth a triumphant feeling in the observer, be it in physical or mental fitness or in opportunity or ability. Thence comes, too, the opposition among gregarious animals to anything which menaces the social norm or its usages, anything which is too small or too great to be reduced to the general average, provided the greatness is not sufficient to inspire awe or fear. And inferiority, too, in the courtship contest is often subject for ridicule. In all these cases, embracing as they do a large proportion of things comic, the instinct for fighting enjoys a triumph, and this enjoyment forms a large part of the general sense of satisfaction.
