No great wrong has ever arisen more clearly to the social consciousness of a generation than has that of commercialized vice in the consciousness of ours, and that we are so slow to act is simply another evidence that human nature has a curious power of callous indifference towards evils which have been so entrenched that they seem part of that which has always been. Educators of course share this attitude; at moments they seem to intensify it, although at last an educational movement in the direction of sex hygiene is beginning in the schools and colleges. Primary schools strive to satisfy the child's first questionings regarding the beginnings of human life and approach the subject through simple biological instruction which at least places this knowledge on a par with other natural facts. Such teaching is an enormous advance for the children whose curiosity would otherwise have been satisfied from poisonous sources and who would have learned of simple physiological matters from such secret undercurrents of corrupt knowledge as to have forever perverted their minds. Yet this first direct step towards an adequate educational approach to this subject has been surprisingly difficult owing to the self-consciousness of grown-up people; for while the children receive the teaching quite simply, their parents often take alarm. Doubtless co-operation with parents will be necessary before the subject can fall into its proper place in the schools. In Chicago, the largest women's club in the city has established normal courses in sex hygiene attended both by teachers and mothers, the National and State Federations of Women's Clubs are gradually preparing thousands of women throughout America for fuller co-operation with the schools in this difficult matter. In this, as in so many other educational movements, Germany has led the way. Two publications are issued monthly in Berlin, which promote not only more effective legislation but more adequate instruction in the schools on this basic subject. These journals are supported by men and women anxious for light for the sake of their children. Some of them were first stirred to action by Wedekind's powerful drama "The Awakening of Spring," which, with Teutonic grimness, thrusts over the footlights the lesson that death and degradation may be the fate of a group of gifted school-children, because of the cowardly reticence of their parents. A year ago the Bishop of London gathered together a number of influential people and laid before them his convictions that the root of the social evil lay in so-called "parental modesty," and that in the quickening of the parental conscience lay the hope for the "lifting up of England's moral tone which has for so long been the despair of England's foremost men."
