“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.”
