 In a draft of a letter, Tolkien distinguished these two kinds of magic with the Greek words "magia" (magic) and "goeteia" (sorcery).While the elves use "goeteia" only for artistic purposes and are always aware of the difference between reality and deception, the enemy employs it to deceive and terrify.Tolkien wrote that neither kind of magic is good or evil, but using them to control free will is the supremely bad motive of his fiction.
