Children often discover, or are taught, the secret vice at a very early age. Sex consciousness and pleasure may be early developed because of some unnatural conditions of the sex organs. For this reason, parents should know that these parts are normal in their children. When children are observed to frequently handle, or scratch these organs, unnatural conditions should be suspected. The child should not be slapped or scolded, rather call in the family physician. Trying to keep a child ignorant concerning this vice is impossible, therefore unwise. There is not one boy in fifty who does not know of the vice, and understands the language used to describe it. Trying to keep a child from vicious companions is good as far as it goes, but the facts are that the child is most likely to discover the vice himself, while it is hardly possible to keep a child entirely away from the vicious. The only sane method is to teach the child the laws of personal purity. If the secret vice is to be prevented, some children should receive council when they are six, others at eight, all by the time they are ten or twelve. Children have inherited lustful tendencies. Their troubles are more largely from within than from without. Hence the children that have been most carefully guarded from bad company and kept in ignorance are usually the ones who are most injured by the secret sin. A single talk to a child is not sufficient. We frequently instruct and appeal to the child to be obedient, truthful and honest; in like manner we should at reasonable periods instruct and encourage him to keep his thoughts and desires pure. SECOND DIVISION HOW TO TEACH SOCIAL PURITY AND SEX TRUTHS TO A CHILD CHAPTER VII THE RIGHT OF A CHILD TO A KNOWLEDGE OF SEX =Social conditions of childhood changed.=--The social conditions of childhood have changed much in the last fifty years. Just as our children have opportunities and possibilities far greater than had we when we were children; so they are exposed to temptations and dangers greater than were we, when we were children. The suggestive, and oft-times positively obscene pictures on post cards, in books and on billboards; the viciously immoral literature; the cheap moving picture shows of to-day, were not social problems threatening the purity of our childhood.
