Fantasy--and all fiction is fantasy of one kind or another--is a mirror. A distorting mirror, to be sure, and a concealing mirror, set at forty-five degrees to reality, but it's a mirror nonetheless, which we can use to tell ourselves things we might not otherwise see. (Fairy tales, as G. K Chesterton once said, are more than true. Not because they tell us that dragons exist, but because they tell us that dragons can be defeated.)
