fairly advanced child a serious person cannot suitably describe all the natural processes of the human body, including sexual intercourse. The child to whom these things are described in a well-considered way, will receive no kind of injury to its moral sentiments; nor will such a description, once more, if it is couched in well-chosen words, provoke in the child any tendency to laughter. The secrecy with which the sexual life is surrounded, confused by many with the sentiment of shame, often gives rise to the belief that the child has the same feelings about the sexual life as the adult. But the unspoiled child has absolutely no feeling that the sexual life is in any way unclean; and for this very reason, no great difficulty arises in the sexual enlightenment of such an unspoiled child--an enlightenment which includes a description of the sexual act. I have myself on several occasions been asked by parents with a proper care for the future morality and health of their children, to undertake the necessary enlightenment of these latter. I am absolutely convinced that when the child has complete trust in the person who effects the enlightenment, the explanation of _everything_ is fully possible. In this book, I have more than once proved that a description of sexual intercourse, appealing as it does rather to the intellectual side of the child's mind, need have no bad influence at all upon its emotional life; and in the further course of this chapter I shall have to speak of the matter once again. I may add here that there are books written specially for the purpose of assisting parents in the instruction of their children in these matters.[147] From what I have written it will have been obvious that I regard the sexual enlightenment of the child as very desirable; but it does not follow from this that I regard it as something that _must_ be undertaken. Not everything is practicable which may seem desirable. We must not forget that there are dangers associated with the sexual enlightenment. It will not be right simply to ignore a reason often alleged against the desirability of sexual enlightenment, namely, that in this way it is possible that the child's thoughts will be turned in the sexual direction. This is unquestionably possible, and the danger can only be avoided by great adroitness. But when we remember that such adroitness is not found everywhere, we shall have to admit, however much we may wish that the sexual enlightenment of children should invariably be effected, that it will often be necessary to dispense with it, because the person suitable to undertake the enlightenment of a particular child is not forthcoming.
