To this I venture to add that by teaching chastity we not merely decrease the demand for prostitutes, but we greatly diminish the supply. Few girls, if any, take to the streets until they have been seduced; and the antecedents of seduction are the morbid exaggeration of the sexual appetite, the lack of self-control, and the selfish hedonism which youthful impurity engenders. The selfishness, and consequent blindness to cruelty, of which I write, manifests itself quite early. A boy of chivalrous feeling, whose blood would boil at any other form of outrage on a girl, will read a newspaper account of rape or indecent assault with a pleasure so intense that indignation and disgust are quite crowded out of his mind. If, repelled by the coarseness of the streets, the young man allows lust or passion to lead him into seduction, he commits a crime the consequences of which are usually cruel in the extreme; for in most cases the seduced girl sinks of necessity into prostitution. So blind, so callous does impurity make even the refined and generous, that many a young man who can be a good son, a good brother, a noble friend, a patriotic citizen, will doom a girl whose only fault is that she is physically attractive--and possibly too affectionate and trusting--to torturing anxiety, to illness, to the horrible suffering of undesired travail, to disgrace, and in nineteen cases out of twenty to ostracism and the infamy of the streets. Murder is a small thing compared with this. Who would not rather that his daughter were killed in her innocence than that she should be doomed to such a fate? Many young men are ignorant of the fact that sexual relations with prostitutes frequently result in the foulest and most terrible of diseases. Venereal diseases, as these are called, commence in the private parts themselves, but the poison which they engender soon attacks other parts of the body and often wrecks the general health. It gives rise to loathsome skin disease, to degeneration of the nervous system and paralysis, to local disease in the heart, lungs, and digestive organs, and to such lowering of vitality as renders the body an easy prey to disease generally. No one is justified in looking upon this risk as a matter of merely private concern. Health is of supreme importance not merely to the personal happiness and success of the man himself, but also to the services he can render to his friends, to his nation, and to humanity. Even if a young man is foolish enough to risk his happiness and success for the sake of animal enjoyment, he cannot without base selfishness and disloyalty disregard the duties he owes to others. Further, the man who suffers from venereal disease is certain to pass its poison on to his wife and children--cursing thus with unspeakable misery those whom of all others it is his duty to protect and bless.
