=The nature of the sexual life.=--The child resembles the father physically, mentally and morally, because the sperm cell formed from the father’s blood, that took part in the initial of the child’s life, had in it the essence of the father’s life, physical, mental and moral. For the same reason the child resembles the mother in these three ways. When the males of the domestic animals are deprived of their generative glands they are not able to develop the peculiar physical masculine characteristics that distinguish them from the females. They are also less independent, more inactive and show less rudimentary manifestations of intelligence. If man be made an eunuch, when he is a boy, he never fully develops masculine characteristics, and he develops little mental and moral tone. Similar results would follow in the female, if her generative glands were removed in childhood. It is quite noticeable that any form of sexual dissipation usually underminds the physical health, weakens the mental faculties and leads to loss in moral tone. It is equally noticeable that the intelligent retention of this energy leads to physical improvement, intellectual brilliancy and soul enlargement. These illustrations reveal that the creative life has other uses than selfish gratification and unselfish reproduction. It is vitally related to the psychic life, health and happiness of the individual. =Other purposes of sex.=--The primary purpose of sex is that of reproduction. There are many reasons why the reproductive function of sex should be limited to a period of twenty-five years--from twenty-five to fifty years of age. Statistics show that this is man’s period of greatest reproductive possibility. Children born to men of younger or older age do not receive as favorable heredity as children born within the period mentioned. The sexual organs, like all other organs, require activity. Two boys are made eunuchs; one at six months of age and the other just before puberty. The last mentioned develops much better in physical, mental and moral tone. This shows that these glands are active, that they generate energy, even before puberty, which is essential to their health and the development of every part of the boy. But even the boy, made an eunuch at fourteen, will be a very defective man at twenty-five. This indicates that the sexual glands are generating a creative energy, during this period of adolescence, that is needed to prepare him for the period of largest possibilities of fatherhood. As a general rule, until he is twenty-four, this sex life should never be expressed for reproductive purposes. The young man has other needs for it. When he arrives at his fiftieth milestone, if he has conserved this energy, in youth, he will thus have added thirty or more years to the fifty already lived. The old men who wear a halo of health, energy, nobility, happiness and purity (there are but few), are men, who in
