One great mystery, the child’s eternal question, occupies its mind more than most parents, most persons, will believe: the question about the origin of man, the question which is customarily answered with a childish tale about a stork (or a big tree in heaven, a large cabbage, or a department store), a tale with which the clever little ones make fools of their elders who go on repeating for many years a story they had long ago ceased to believe. Behind all the child’s curiosity there lurks the one great question: “Where do children come from?” One will never go wrong in concluding that a child who is plaguing his elders with a thousand stupid and clever questions is suffering from a kind of obsession, an obsessive questioning, behind which lies the one great and important question that troubles all children. On this subject the child cannot speak with its parents. Instinctively it feels that here is a great mystery that is being withheld from it and whose solution the parents have put off for a future time. It is during childhood friendship and in connection with this question that sexuality plays its first trump. It is a pity that human beings so easily forget their own childhood, else parents would not be so blind in this regard. In the northern psychologist’s, Arne Gaborg’s, best work “By Mama” there is a wonderful scene copied direct from nature: Two little girls are sitting on the basement stairs whispering to each other their latest bit of information about the great mystery; gradually it grows dark and an inexplicable dread of something great, threatening, mysterious, fills their trembling souls; it is that fear which faithfully accompanies love throughout life and whose dark wing has just barely brushed their innocent childhood.
