In the case of a girl it is better that she learns rhythmic movements; in the case of a boy it is better that he learns gymnastics. For a girl rhythmic movements serve the same purpose, and yet they do not hurt her girlish characteristics. For the boy gymnastics suffice, and these keep each in their own direction. The energy in a boy that makes him so restless and uncomfortable will be used in gymnastics, and that will bring about balance of mind.
