"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."
"We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all."
"I don't know why we are here, but I'm pretty sure that it is not in order to enjoy ourselves."
"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."
