"We tend to imagine that readers of fantasy recognize that what they’re reading is make-believe, which is certainly true today, but wasn’t necessarily so in ancient times. People of ages past regarded fantasies and myths as nothing less than fact. Back then, the real world and the world of magic were mixed together as an inseparable whole, and a large part of the appeal of magical fantasy was its perceived realism. Now, its sense of realism is gone for good, which is why modernity can produce only fairy tales, never myths."
