The consolation of fairy stories, the joy of the happy ending: or more correctly of the good catastrophe, the sudden joyous "turn" (for there is no true end to any fairy tale); this joy, which is one of the things which fairy stories can produce supremely well, is not essentially "escapist," nor "fugitive." In its fairy tale--or otherworld--setting, it is a sudden and miraculous grace: never to be counted on to recur. It does not deny the existence of dyscatastrophe, of sorrow and failure: the possibility of these is necessary to the joy of deliverance; it denies (in the face of much evidence, if you will) universal final defeat and in so far is evangelium, giving a fleeting glimpse of Joy; Joy beyond the walls of the world, poignant as grief.It is the mark of a good fairy-story, of the higher and more complete kind, that however wild its events, however fantastic or terrible the adventures, it can give to child or man that hears it, when the 'turn' comes, a catch of the breath, a beat and lifting of the heart, near to (or indeed accompanied by) tears, as keen as that given by any form of literary art, and having a peculiar quality.
