Probably there is an imperceptible touch of something permanent that one feels instinctively to adhere to true humour, whereas wit may be the mere conversational shooting up of "smartness"--a bright feather, to be blown into space the second after it is launched. . . Wit seems to be counted a very poor relation to Humour. . . . Humour is never artificial.
