"To many, Fantasy, this sub-creative art which plays strange tricks with the world and all that is in it, combining nouns and redistributing adjectives, has seemed suspect, if not illegitimate. To some it has seemed at least a childish folly, a thing only for peoples or for persons in their youth. As for its legitimacy I will say no more than to quote a brief passage from a letter I once wrote to a man who described myth and fairy-story as “lies”; though to do him justice he was kind enough and confused enough to call fairy-story-making “Breathing a lie through Silver.” :
'Dear Sir,' I said—Although now long estranged,
Man is not wholly lost nor wholly changed.
Disgraced he may be, yet is not de-throned,
and keeps the rags of lordship once he owned:
Man, Sub-creator, the refracted Light
through whom is splintered from a single White
to many hues, and endlessly combined
in living shapes that move from mind to mind.
Though all the crannies of the world we filled
with Elves and Goblins, though we dared to build
Gods and their houses out of dark and light,
and sowed the seed of dragons—'twas our right
(used or misused). That right has not decayed:
we make still by the law in which we're made.”
- J.R.R. Tolkein "On Faiery Stories"
