Fairy tale does not deny the existence 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...giving a fleeting glimpse of Joy; Joy beyond the walls of the world, poignant as grief.
J. R. R. TolkienGandalf: Confound it all, Samwise Gamgee. Have you been eavesdropping? Sam: I ain't been droppin' no eaves sir, honest. I was just cutting the grass under the window there, if you'll follow me. Gandalf: A little late for trimming the verge, don't you think? Sam: I heard raised voices. Gandalf: What did you hear? Speak. Sam: N-nothing important. That is, I heard a good deal about a ring, and a Dark Lord, and something about the end of the world, but... Please, Mr. Gandalf, sir, don't hurt me. Don't turn me into anything... unnatural.
