Not how the world is, but that it is, is the mystery. - 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."

"But some of the greatest achievements in philosophy could only be compared with taking up some books which seemed to belong together, and putting them on different shelves; nothing more being final about their positions than that they no longer lie side by side. The onlooker who doesn’t know the difficulty of the task might well think in such a case that nothing at all had been achieved."

"An honest religious thinker is like a tightrope walker. He almost looks as though he were walking on nothing but air. His support is the slenderest imaginable. And yet it really is possible to walk on it."

"The real question of life after death isn't whether or not it exists, but even if it does what problem this really solves."

"A serious and good philosophical work could be written consisting entirely of jokes."
