Fairy tales do not tell children the dragons exist. Children already know that dragons exist. Fairy tales tell children the dragons can be killed.
Fear isn't so difficult to understand. After all, weren't we all frightened as children? Nothing has changed since Little Red Riding Hood faced the big bad wolf. What frightens us today is exactly the same sort of thing that frightened us yesterday. It's just a different wolf. This fright complex is rooted in every individual.
Great heroes need great sorrows and burdens, or half their greatness goes unnoticed. It is all part of the fairy tale.
Peter S. Beagle
The consolation of fairy stories, the joy of the happy ending; or more correctly, the good catastrophe, the sudden, joyous "turn" (for there is no true end to a fairy tale); this joy, which is one of the things that fairy stories can produce supremely well, is not essentially escapist or fugitive. In it's fairy tale or other world setting, it is a sudden and miraculous grace, never to be counted on to reoccur. It does not deny the existence of a catastrophe, or 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.
Deeper meaning resides in the fairy tales told to me in my childhood than in the truth that is taught by life.
Friedrich von Schiller
