“What is more, as J. R. R. Tolkien reminds us in his great essay on Beowulf, there is a danger that attends rational and scientific description: “a plain pure fairy story dragon” can be ruined at the hands of a logical analysis. The interpreter, “unless he is careful, and speaks in parables, will kill what he is studying by vivisection, and he will be left with a formal or mechanical allegory, and, what is more, probably with one that will not work. For myth is alive at once and all its parts, and dies before it can be dissected.”
