Experience must have taught educators that the task of moulding the sexual will of the next generation can only be carried out by beginning to impose their influence very early, and intervening in the sexual Life of children before puberty, instead of waiting till the storm bursts. Consequently almost all infantile sexual activities are forbidden or made disagreeable to the child; the ideal has been to make the child’s life asexual, and in course of time it has come to this that it is really believed to be asexual, and is given out as such, even at the hands of science. In order then to avoid any contradiction with established beliefs and aims, the sexual activity of children is overlooked—no small achievement, by the way—while science contents itself with otherwise explaining it away. The little child is supposed to be pure and innocent; he who says otherwise shall be condemned as a hardened blasphemer against humanity’s tenderest and most sacred feelings. The children alone take no part in this convention; they assert their animal nature naïvely enough and demonstrate persistently that they have yet to learn their “purity.” Strange to say, those who deny sexuality in children are the last to relax educative measures against it; they follow up with the greatest severity every manifestation of the “childish tricks” the existence of which they deny. Moreover, it is theoretically of great interest that the time of life which most flagrantly contradicts the prejudice about asexual childhood, the years of infancy up to five or six, is precisely the period which is veiled by oblivion in most people’s memories; an oblivion which can only be dispelled completely by analytic investigation but which is nevertheless sufficiently penetrable to allow of the formation of single dreams.
