Moll in his wise and comprehensive work, The Sexual Life of the Child (German ed., p. 225), lays it down emphatically that "we must clearly realize at the outset that the complete exclusion of sexual stimuli in the education of children is impossible." He adds that the demands made by some "fanatics of hygiene" would be dangerous even if they were practicable. Games and physical exercises induce in many cases a considerable degree of sexual stimulation. But this need not cause us undue alarm, nor must we thereby be persuaded to change our policy of recommending such games and exercises.

See Frau Maria Lischnewska's excellent pamphlet, Geschlechtliche Belehrung der Kinder, first published in Mutterschutz, 1905, Heft 4 and 5. This is perhaps the ablest statement of the argument in favour of giving the chief place in sexual hygiene to the teacher. Frau Lischnewska recognizes three factors in the movement for freeing the sexual activities from degradation: (1) medical, (2) economic, and (3) rational. But it is the last—in the broadest sense as a comprehensive process of enlightenment—which she regards as the chief. "The views and sentiments of people must be changed," she says. "The civilized man must learn to gaze at this piece of Nature with pure eyes; reverence towards it must early sink into his soul. In the absence of this fundamental renovation, medical and social measures will merely produce refined animals."
