"The Thousand and One Nights, with its magnificent apparatus of genii and afrits, is the greatest work of fantasy that has ever been evolved by tradition, and given literary form. But it, alas, is not English, and has no English equivalent. The Western world does not seem to have conceived the necessity of fairy-tales for grown-ups — though it has been suggested that the modern detective story is an equivalent — and that is perhaps why it condemns them to a life of unremitted toil."
