According to Norman Malcolm's memoir,
Wittgenstein once said that a serious and philosophical work could be written that would consist entirely of jokes (without being facetious).
Ray Monk wants to know if Wittgenstein ever wrote this down himself; and Tim Madigan, in Philosophy Now, wonders what he meant by it. I'm curious whether anyone has ever tried such a thing--I mean the "of jokes" part, not the "without being facetious."
