It is obvious that sex instruction may be given blunderingly even with the greatest good-will; I am, indeed, exceedingly doubtful of the efficacy of any kind of formal teaching. Certainly set lessons, or even “arranged talks,” should not be given to young children. All children harbour curiosities regarding their bodily structure and the basis of life. In an atmosphere of trust, sooner or later they will express these natural curiosities in a tentative, haphazard way. This is the psychological moment for the mother’s teaching. The question asked must be answered truthfully and in terms simplified to the comprehension of the child. The reply must have the air of being both candid and confidential: that is to say, it must satisfy curiosity and at the same time leave the impression that such subjects are to be avoided in general conversation, not because they are “nasty,” but because they are so sacred and intimate that they should be mentioned only to those the child loves and respects. The ideal must ever be to educate through love, to avoid always repressive measures, and to aid the expression of the normal sex instincts: let the child establish its own psychic individuality. Our unconscious example must always be far stronger in its result on the child’s mind than anything we can say. Of what use can our teaching be, if, through our own want of purity, the concealments that breed curiosity and shame, are evident in all our attitude to our bodies and to the physical facts of our being? The child is not shown the duty of reverence for himself; he is not taught the beauty of all the processes of his young life; the sex organs are left without proper names, and the child is told that it must not speak of these parts. We are continuously careless in our conversations and in our acts before our children. We take them to see picture plays and allow them to read books and tell them stories in which love is vulgarised, and all kinds of false statements are allowed. In these and in numerous other ways, weeds are caused by our folly to spring up in the child’s mind. We can never undo by any teaching a sense of shame in sex and love that our actions and thoughtless words have revealed to the quick intelligence of the child. It is entirely false to think that the facts of sex plainly and simply told will shock and seem strange to the young child. It is to the prurient only that there is anything ugly or disillusioning in birth and love. The child will receive your information with wonder and guileless delicacy. The mother need have no fear of her child, only of herself. The error in all these cases is the error of our own impurity of thought; the hateful idea that the facts of sex are ugly and disillusioning. Here we have the key to the whole problem: it explains the utter helplessness and weakness of our attitude. It will be very long before this can be changed; the evil is rooted so deeply in almost all of us.
