In an unsent draft of a letter in 1954, Tolkien distinguished two kinds of magic with the Greek words μαγεία ("mageia" "ordinary magic") and γοητεία ("goeteia", "witchcraft"). He 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 explained that both could be used for good and bad purposes, but neither was inherently good or bad in itself. In his view, using them to control free will was the most extreme kind of evil.
