I don't need to know everything, I just need to know where to find it, when I need it

If I had an hour to solve a problem and my life depended on the solution, I would spend the first 55 minutes determining the proper question to ask, for once I know the proper question, I could solve the problem in less than five minutes.

When a man, after long years of searching, chances upon a thought which discloses something of the beauty of this mysterious universe, he should not therefore be personally celebrated. He is already sufficiently paid by his experience of seeking and finding.

I do not play games. There is not time for it. When I get through with work, I don't want anything that requires the working of the mind.

What I seek to accomplish is simply to serve with my feeble capacity truth and justice, at the risk of pleasing no one.

If one asks the whence derives the authority of fundamental ends, since they cannot be stated and justified merely by reason, one can only answer: they exist in a healthy society as powerful traditions, which act upon the conduct and aspirations and judgments of the individuals; they are there, that is, as something living, without its being necessary to find justification for their existence.

The true sign of intelligence is not knowledge but imagination.
