To find the sources of pleasure in dancing we must go back to the common ground of satisfaction in obeying the impulse for motion, yet it is not easy to assign a general explanation for the peculiar charm of rhythmical movement. Spencer holds that passionate excitement naturally manifests itself in rhythmic repetition; while Minor, on the contrary, sees in it the expression of a prudential instinct to restrain the fury of passionate feeling.[188] As Schiller, too, says: “Es ist des Wohllauts mächtige Gottheit, Die zum geselligen Tanz ordnet den tobenden Sprung, Die der Nemesis Gleich, an des Rhythmus goldenem Zügel Lenkt die brausende Lust und die verwilderte zähmt.”[189] This view is quite plausible when applied to the social effect of dancing, as Grosse has pointed out. Rhythm does subdue and order “riotous lust,” and afford a harmless outlet to the general need for some expression of it. Yet it would be a mistake to suppose that its effect is always subduing, since, as a matter of fact, it often leads to the wildest tumult. “Oh, thou bold gamester,” an old song runs, “Make for us a long row, Hip, hip, hurrah! how he can go! Heart, lungs, and liver he will overthrow.”[190] Spencer’s remark makes it clear, from the other point of view, that rhythm is a most suitable instrument for the expression of passionate emotion, be it sad or joyful, but fails to explain why it is in itself intensely exciting and pleasurably so. Grosse justly says of Spencer’s view: “According to this theory the rhythm of dancing movements seems to be only a sharply and strongly intensified form of locomotion. It does not at all explain the pleasurable quality of rhythm, and if we are unwilling to accept description in lieu of explanation we can only regard this statement of fact as introductory to further investigation.” Since Darwin’s theory, mentioned above, has as yet found little substantial proof, the intoxicating effects of rhythmic motion must find some other explanation here. Such movements are employed among most peoples as a means of producing ecstatic conditions. Selenkas gives a simple instance from Borneo: “The candidate [for the office of doctor] was led before the Manangs as they squatted on the ground. The Dekan, or spokesman, addressed him, and, rising, anointed his forehead with oil and ordered him to go around the ring bearing a lance to which was hung a medicine bag. The Dekan followed him at a trot, and their speed was constantly increased as the accompanying song of the others grew louder, until at last the novitiate, gasping and stumbling as if hypnotized, broke down.”[191]
