Regarding faerie, it is a “perilous land, and in it are pitfalls for the unwary and dungeons for the overbold.” - J. R. R. Tolkien, “On Fairy-stories,” The Tolkien Reader, p. 33
“The realm of fairy-story is wide and deep and high and filled with many things: all manner of beasts and birds are found there; shoreless seas and stars uncounted; beauty that is an enchantment, and an ever-present peril; both joy and sorrow as sharp as swords. In that realm a man may, perhaps, count himself fortunate to have wandered, but its very richness and strangemeness tie the tongue of a traveller who would report them. And while he is there it is dangerous for him to ask too many questions, lest the gates should be shut and the keys be lost.” - J. R. R. Tolkien, “On Fairy-stories,” The Tolkien Reader, p. 33
“Fantasy is a natural human activity. It certainly does not destroy or even insult reason; and it does not either blunt the appetite for, nor obscure the perception of, scientific verity.” - J. R. R. Tolkien, "On Fairy-stories, The Tolkien Reader, p. 74-75
Regarding the Eucatastrophe - the sudden joyous “turn,” “sudden and miraculous grace” - J. R. R. Tolkien, "On Fairy-stories," The Tolkien Reader, p. 86
"The value of the myth is that it takes all the things we know and restores to them the rich significance which has been hidden by ‘the veil of familiarity’. The child enjoys his cold meat (otherwise dull to him) by pretending it is buffalo, just killed with his own bow and arrow. And the child is wise. The real meat comes back to him more savoury for having been dipped in a story; you might say that only then is it the real meat. . . . we do not retreat from reality: we rediscover it. As long as the story lingers in our mind, the real things are more themselves. . . . By dipping them in myth we see them more clearly. . .[regarding the book], we know at once that it has done things to us. We are not quite the same men.” - C. S. Lewis, "Tolkien's Lord of the Rings," On Stories, p. 138-139
. . . give a child a single valuable idea, and you have done more for his education than if you had laid upon his mind the burden of bushels of information . . . - Charlotte Mason, Volume 1: Home Education, p. 174
