This notion of something smooth and slow like the ascent of a slope, is a great part of the illusion. It is an illogically as well as an illusion; for slowness has really nothing to do with the question. An event is not any more intrinsically intelligible or unintelligible because of the pace at which it moves. For a man who does not believe in a miracle, a slow miracle would be just as incredible as a swift one. The Greek witch may have turned sailors to swine with a stroke of the wand. But to see a naval gentleman of our acquaintance looking a little more like a pig every day, till he ended with four trotters and a curly tail would not be any more soothing. It might be rather more creepy and uncanny. The medieval wizard may have flown through the air from the top of a tower; but to see an old gentleman walking through the air in a leisurely and lounging manner, would still seem to call for some explanation. Yet there runs through all the rationalistic treatment of history this curious and confused idea that difficulty is avoided or even mystery eliminated, by dwelling on mere delay or on something dilatory in the processes of things….The question here is the false atmosphere of facility and ease given by the mere suggestion of going slow; the sort of comfort that might be given to a nervous old woman traveling for the first time in a motor-car.
―G.K. Chesterton, The Everlasting Man
