An infant once given the habit of a regular time for its food demands it at that time, although it has no idea of time. This is accounted for by the fact that the very nature of life is rhythm. The infant begins its life on earth by moving its arms and legs, thus showing the rhythm of its nature, and illustrating the philosophy which teaches that rhythm is the sign of life. The inclination to dance shown by every man illustrates also that innate nature of beauty which chooses rhythm for its expression.
