This powerlessness of the law and the police is well recognized by lawyers familiar with the matter. Thus F. Werthauer (Sittlichkeitsdelikte der Grosstadt, 1907) insists throughout on the importance of parents and teachers imparting to children from their early years a progressively increasing knowledge of sexual matters.
"Parents must be taught how to impart information," remarks E. L. Keyes ("Education upon Sexual Matters," New York Medical Journal, Feb. 10, 1906), "and this teaching of the parent should begin when he is himself a child."
Moll (op. cit., p. 224) argues well how impossible it is to preserve children from sights and influence connected with the sexual life.
