Almost every adult in a Christian community is more or less diseased nervously as a result of the taboo on sex knowledge when he or she was young. And the sense of sin which is thus artificially implanted is one of the causes of cruelty, timidity, and stupidity in later life. There is no rational ground of any sort or kind in keeping a child ignorant of anything that he may wish to know, whether on sex or on any other matter. And we shall never get a sane population until this fact is recognized in early education, which is impossible so long as the churches are able to control educational politics.
