Deliberately I avoid discussing the question as to the precise words and phrases with which the child's enlightenment is to be effected. Moreover, this question is subordinate to another, namely, to what extent instruction in natural science has prepared the way, in the child's mind, for such enlightenment. Both in Germany and in Austria, schemata have been drawn up for systematic preparation of this kind.[145] Speaking generally, we may draw the following conclusions. We have to distinguish according to the age of the child with which we have to deal. Where we have to caution a young man about to leave one of the higher schools, about the dangers of venereal infection, our difficulties are inconsiderable. But where we have to do with a girl of eight, who has asked her mother where her baby brother has come from; or with a boy of fourteen, whom we wish to protect because he has taken to sexual malpractices with his school-fellows, our difficulties are great. In such cases, tact, which cannot always be taught, and a desire for the best interests of the child, must show us the right path. It is obvious that each case will require individual consideration and treatment. An intelligent mother, who constitutes half the child's world and more, can describe these matters to her child, can even describe the sexual act, whose existence most persons prefer to conceal from children. It is by no means impossible to present even this act to the child's mind in a tactful way. It can be done in a poetical manner, and yet without departing from the strict truth. The same considerations apply to the act of birth. In a book dealing with this subject, a mother is asked by her child where children come from, and she answers as follows: "You see, little one, how fruit grows upon a tree; in just the same way, little children grow within the body of the mother." Beyond question, there is no justification for the assumption that sexual enlightenment can be effected only in a repulsive manner; and this view depends merely upon the fact that through a perversion of moral ideas certain persons regard as unclean things which are essentially clean. Everything depends upon the person who effects the enlightenment, upon finding a suitable opportunity, and upon choosing words and phrases adapted to the child's intelligence. Success will often follow upon replying in an illuminating way to some chance question of the child. In other cases, there may be indications for making the enlightenment part of a festival occasion--a method described in an old book, in which the father effects the enlightenment of his children to the accompaniment of public prayers.[146] The description shows a truly religious spirit, and a genuine love for children; it shows, further, that natural processes may be described truthfully to children without wounding in any way their sense of shame. There is no ground whatever for the belief that to a
