It is admitted, one may hope, that common things are never commonplace. Birth is covered with curtains precisely because it is a staggering and monstrous prodigy. Death and first love, though they happen to everybody, can stop one’s heart with the very thought of them. But while this is granted, something further may be claimed. It is not merely true that these universal things are strange; it is moreover true that they are subtle. In the last analysis most common things will be found to be highly complicated. Some men of science do indeed get over the difficulty by dealing only with the easy part of it: thus, they will call first love the instinct of sex, and the awe of death the instinct of self-preservation. But this is only getting over the difficulty of describing peacock green by calling it blue. There is blue in it. That there is a strong physical element in both romance and the Memento Mori makes them if possible more baffling than if they had been wholly intellectual. No man could say exactly how much his sexuality was colored by a clean love of beauty, or by the mere boyish itch for irrevocable adventures, like running away to sea. No man could say how far his animal dread of the end was mixed up with mystical traditions touching morals and religion. It is exactly because these things are animal, but not quite animal, that the dance of all the difficulties begins. The materialists analyze the easy part, deny the hard part and go home to their tea. It is complete error to suppose that because a thing is vulgar therefore it is not refined; that is, subtle and hard to define. A drawing-room song of my youth which began “In the gloaming, O, my darling,” was vulgar enough as a song; but the connection between human passion and the twilight is none the less an exquisite and even inscrutable thing. Or to take another obvious instance: the jokes about a mother-in-law are scarcely delicate, but the problem of a mother-in-law is extremely delicate. A mother-in-law is subtle because she is a thing like the twilight. She is a mystical blend of two inconsistent things--law and a mother. The caricatures misrepresent her; but they arise out of a real human enigma. “Comic Cuts” deals with the difficulty wrongly, but it would need George Meredith at his best to deal with the difficulty rightly. The nearest statement of the problem perhaps is this: it is not that a mother-in-law must be nasty, but that she must be very nice.
