Melissa de la Cruz quote: “Remember all fairy tales end at some point.”

“This was not a fairy-tale castle and there was no such thing as a fairy-tale ending, but sometimes you could threaten to kick the handsome prince in the ham-and-eggs.”

“Fairy tales and more fairy tales.”

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

in response to a mother who wanted her son to become a scientist and asked Einstein what reading material to give him
Found in Montana Libraries: Volumes 8-14 (1954), p. cxxx http://books.google.com/books?id=PpwaAAAAMAAJ&q=%22more+fairy+tales%22#search_anchor. The story is given as follows: "In the current New Mexico Library Bulletin, Elizabeth Margulis tells a story of a woman who was a personal friend of the late dean of scientists, Dr. Albert Einstein. Motivated partly by her admiration for him, she held hopes that her son might become a scientist. One day she asked Dr. Einstein's advice about the kind of reading that would best prepare the child for this career. To her surprise, the scientist recommended 'Fairy tales and more fairy tales.' The mother protested that she was really serious about this and she wanted a serious answer; but Dr. Einstein persisted, adding that creative imagination is the essential element in the intellectual equipment of the true scientist, and that fairy tales are the childhood stimulus to this quality." However, it is unclear from this description whether Margulis heard this story personally from the woman who had supposedly had this discussion with Einstein, and the relevant issue of the New Mexico Library Bulletin does not appear to be online.

“The happy ending of the fairy tale, the myth, and the divine comedy of the soul, is to be read, not as a contradiction, but as a transcendence of the universal tragedy of man.”

Joseph Campbell book The Hero with a Thousand Faces

Campbell follows with a quote from Ovid's Metamorposes, "All things are changing; nothing dies..."
Chapter 2
The Hero with a Thousand Faces (1949)
Context: The happy ending of the fairy tale, the myth, and the divine comedy of the soul, is to be read, not as a contradiction, but as a transcendence of the universal tragedy of man.... Tragedy is the shattering of the forms and of our attachment to the forms... the two are the terms of a single mythological theme... the down-going and the up-coming (kathados and anodos), which together constitute the totality of the revelation that is life, and which the individual must know and love if he is to be purged (katharsis=purgatorio) of the contagion of sin (disobedience to the divine will) and death (identification with the mortal form).
