Tolkien distinguishes ordinary magic from witchcraft, the latter always deceptive, stating that either type could be used for good or evil.
[1] He believed that Tolkien considered magic as something negative, associated with modern science and machinery, as in his essay On Fairy-Stories: a means of "power ... [and] domination of things and wills" that corrupts those who use it, for example, trapping the wizard Saruman in his desire for ultimate knowledge and order.
[13] Such magic contrasts with the enchantment of Tolkien's fictional elvish lands, which he saw as a form of pure art and an appreciation of the wonders of the world.
[T 31] Tolkien stated that these could not be acquired by studying ancient lore or books of spells, but that they were "inherent power not possessed or attainable by Men as such".
He saw no colour but those he knew, gold and white and blue and green, but they were fresh and poignant, as if he had at that moment first perceived them... On the land of Lórien there was no stain.
[T 34]Curry cites what he calls Max Weber's crucial insight, namely that "The unity of the primitive image of the world, in which everything was concrete magic [his italics], has tended to split into rational cognition and mastery of nature, on the one hand, and into 'mystic' experiences, on the other".
In each of the four uses of a stone in The Lord of the Rings, a true image is shown, but the viewer draws a false conclusion from the facts.
The horn, he explains, is "a magic one, though only modestly so":[12] blowing it brings joy to his friends in arms, fear to his enemies, and it awakens the Hobbits to purify the Shire of Saruman's ruffians.
