The Eugenists also believe in educating the father, or prospective father. They hold that every man should be made acquainted with the duties and responsibilities of fatherhood, and should so conduct and order his life that the production and rearing of a family should result as a consummation of a long cherished ideal. The man should be taught to prepare himself, physically, mentally, and morally, for his coming responsibility to the race. He should also be taught to respect and regard motherhood, and to make it his business to secure and preserve the best possible conditions for the mother of his own children, and the mothers of other men's children, not as an act of mere sentiment, but as a public duty, a patriotic service, a racial obligation. The Eugenists believe in teaching young men and young women on the subject of sexual physiology and psychology. They hold that the race is now criminally negligent in such matters, and that young men and women, by the thousands, enter into the state of marriage and parenthood with no knowledge regarding the sacred functions which they are to bring into activity. They believe that the first requisite of scientific parenthood is and must be a sane knowledge of the physiology of sex, and the psychology of sex. There must be sane education concerning the sexual organism, its laws, its functions, its normal and healthy condition, its anatomy, physiology and hygiene. The average physician of several years' experience can tell tales of almost incredible ignorance on the part of persons who have recently entered into the relationship of marriage. In some cases the ignorance is more than a mere absence of knowledge, for it consists of an array of false-knowledge, untruthful ideas, of often serious importance. It is sad enough to think how the ignorance and false-knowledge may work results hurtful to the young couple themselves, but it is even sadder to realize that these same ignorant or wrongly-informed young persons must gain their real knowledge through sad experience which is to be paid for not only by themselves but also by their children. It is a hard saying, but true that "the knowledge of the majority of young parents is gained by experience paid for by their unborn children."
