Art of the same sort, if more skilled and effortless, the elves can also use, or so reports seem to show; but the more potent and specially elvish craft I will, for lack of a less debatable word, call Enchantment. Enchantment produces a Secondary World into which both designer and spectator can enter, to the satisfaction of their senses while they are inside; but in its purity it is artistic in desire and purpose. Magic produces, or pretends to produce, an alteration in the Primary World. It does not matter by whom it is said to be practised, fay or mortal, it remains distinct from the other two; it is not art but a technique; its desire is power in this world, domination over things and wills.
