In order to make head against the horrible evils which accompany men’s profligacy and women’s prostitution, and to prevent the moral and physical disasters which result from young men’s and young women’s ignorance about the natural processes of reproduction in the human species and about the laws of health in those processes, it is indispensable that systematic instruction should be given to all young children and young people in the processes of reproduction and growth in plants and animals, in the general rules of hygiene, in the natural, wholesome processes of reproduction in the human species, and at last in the diseases and social disorders which follow violations of nature’s laws concerning the relations of the sexes. The bitter experience of the Christian world in regard to the venereal diseases and their consequences demonstrated this proposition. =Policy of silence a failure.=--Wherever anyone undertakes to discuss this subject in public, he is met by two adverse opinions which are firmly held by multitudes of well-meaning people. The first is the opinion that these are unclean subjects, about which the less said the better. This is the policy of silence concerning all sexual relations and processes, natural or unnatural, rightful or sinful, which has prevailed for centuries in both barbarous and civilized countries. There is but one thing to be said about this policy of silence, namely, that it has failed, everywhere and always. It has not prevented the spread and increase of sexual wrong-doing and of the horrible resultant diseases, degradations, and destructions. For the prevention and eradication of any great social or governmental wrong, publicity, discussion, and the awakening of a righteous public sentiment in the great mass of the people concerned have always been, and always must be, necessary.
