In undertaking the sexual enlightenment of the child, those phenomena of the sexual life should not be forgotten which are shown by experience to arouse in the ripening child, now curiosity, and now anxiety--and the chief among these are involuntary sexual orgasm and menstruation. Imagine the state of mind of the girl who has never heard a word about menstruation, and awakens one morning with blood flowing from the genital organs; or that of the boy, who has his first nocturnal seminal emission, without having received any information as to its significance. Similar considerations apply to some of the other signs of puberty; and especially to the growth of the pubic hair, which has made many a child extremely anxious. Although, by the time this age is reached, a child has commonly been sufficiently informed about these things by his playfellows, we meet with instances in which nothing of the kind has occurred. Hitherto I have been considering the hygienic grounds for effecting sexual enlightenment; but there are also important ethical reasons for such enlightenment. It is not possible in our life to speak the truth always and unconditionally; but this fact does not give us the right to lie to children without good cause. Especially dangerous is it to relate to children fables about the stork or the cabbage-garden, at a time when they have long been enlightened about sex from other sources. I recall the case of a girl seven years of age, whose mother was still in the habit of telling her that babies were brought by the storks; but this child was accustomed to join with other girls and boys in playing at "father, mother, and midwife," wherein they displayed a comparatively exact knowledge of the processes of reproduction and birth. We are not surprised when a woman tells us that as a child her confidence in her mother was seriously shaken from the moment when she was enlightened by others concerning the sexual life, and she recognised that what her mother had told her about the matter was quite untrue. I do not mean to imply that stories of the stork and cabbage-garden variety are to be altogether excluded. It would be as reasonable to prohibit all kinds of fairy tales. Some tell us that we should tell children fairy stories only so long as they regard the whole of life as a fairy tale. But in view of the vivid imagination of childhood, no such sharp distinction is practicable. Let the reader recall his own childhood. Does the child regard the fairy tale as a lie, even after he has began to doubt if the world of fairy stories has any actual existence? Certainly not. Similarly with regard to the stork fable. I consider that the complete suppression of this fable, unless we replace it with some like poetical fancy, can do nothing but harm to the child's nature. All that we must ask is that such a story shall not for too long be put before the child as fact. When the child's development has gone far enough, it will be
