More quotes by Ludwig Wittgenstein

"Humor is not a mood but a way of looking at the world. So if it is correct to say that humor was stamped out in Nazi Germany, that does not mean that people were not in good spirits, or anything of that sort, but something much deeper and more important."
"A serious and good philosophical work could be written consisting entirely of jokes."
"We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all."
"Not how the world is, but that it is, is the mystery."
