Tolkien, who was inspired by Chesterton wrote:

Although now long estranged, Man is not wholly lost nor wholly changed. Dis-graced 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.

Fantasy remains a human right: we make in our measure and in our derivative mode, because we are made: and not only made, but made in the image and likeness of a Maker. J.R.R. Tolkien, Tolkien On Fairy-stories
