“Merely having an open mind is nothing; the object of opening a mind, as of opening the mouth, is to shut it again on something solid.”
He also said (in relation to a slow miracle to that of a fast one):
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.... 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 a mystery eliminated, by dwelling on mere delay or on something dilatory in the process of things.... The ultimate question is why [things] go at all; and anybody who really understands that question will know that it always has been and always will be a religious question; or at any a rate a philosophical or metaphysical question. And most certainly he will not think the question answered by some substitution of gradual for abrupt change.
