“Moreover, humour is itself but a superficial view of that which is in truth both tragic and terrible—the contrast between human pretence and cosmic mechanical reality. Humour is but the faint terrestrial echo of the hideous laughter of the blind mad gods that squat leeringly and sardonically in caverns beyond the Milky Way. It is a hollow thing, sweet on the outside, but filled with the pathos of fruitless aspiration. All great humorists are sad—Mark Twain was a cynic and agnostic, and wrote "The Mysterious Stranger" and "What Is Man?" When I was younger I wrote humorous matter—satire and light verse—and was known to many as a jester and parodist. … But I cannot help seeing beyond the tinsel of humour, and recognising the pitiful basis of jest—the world is indeed comic, but the joke is on mankind.”
