“Electric lamps have come to stay,” they say. Long ago Chesterton truly remarked that, as soon as he heard that anything “had come to stay,” he knew that it would be very soon replaced—indeed regarded as pitiably obsolete and shabby. “The march of Science, its tempo quickened by the needs of war, goes inexorably on ... making some things obsolete, and foreshadowing new developments in the utilization of electricity”: an advertisement. This says the same thing only more menacingly. The electric street-lamp may indeed be ignored, simply because it is so insignificant and transient. Fairy-stories, at any rate, have many more permanent and fundamental things to talk about. Lightning, for example. The escapist is not so subservient to the whims of evanescent fashion as these opponents. He does not make things (which it may be quite rational to regard as bad) his masters or his gods by worshipping them as inevitable, even “inexorable.” J.R.R. Tolkien, "On Fairy Stories"
