“ Is childhood not rather that period of life which is distinguished by the lack of the sexual impulse? No, gentlemen, it is not at all true that the sexual impulse enters into the child at puberty, as the devils in the gospel entered into the swine. The child has his sexual impulses and activities from the beginning, he brings them with him into the world, and from these the so-called normal sexuality of adults emerges by a significant development through manifold stages. ”
