“To learn that we have said or done a foolish thing, that is nothing; we must learn that we are nothing but fools, a far broader and more important lesson.”

“If what we learn is no more than what we expect to learn, then we have learned nothing at all.”

“There is nothing in the path of life that we don't already know before we start. Nothing important is learned; it is simply remembered.”

“For a human being, nothing comes naturally,' said Grumman. 'We have to learn everything we do.”

“Love is wise; hatred is foolish. In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other, we have to learn to put up with the fact that some people say things that we don't like. We can only live together in that way. But if we are to live together, and not die together, we must learn a kind of charity and a kind of tolerance, which is absolutely vital to the continuation of human life on this planet.”

“We live and learn, or, perhaps more importantly we learn and live.”
