It is ugly ducklings, grown either into swans or into remarkably big, remarkably ugly ducks, who are responsible for most works of art; and yet how few of these give a truthful account of what it was like to be an ugly duckling!—it is almost as if the grown, successful swan had repressed most of the memories of the duckling's miserable, embarrassing, magical beginnings. (The memories are deeply humiliating in two ways: they remind the adult that he was once more ignorant and gullible and emotional than he is; and they remind him that he once was, potentially, far more than he is.)
