What I must do is all that concerns me, not what people think. This rule,equally arduous in actual and intellectual life, may serve for the whole distinction between greatness and meanness. It is the harder, because you will always find those who think they know what is your duty better than you know it. It is easy in the world to live after the world's opinion; it is easy in solitude to live after our own; but the great man is he who in the midst of the crowd keeps with perfect sweetness the independence of solitude.
Examinations, sir, are pure humbug from beginning to end. If a man is a gentleman, he knows quite enough, and if he is not a gentleman, whatever he knows is bad for him.
Men grind and grind in the mill of a truism, and nothing comes out but what was put in. But the moment they desert the tradition for a spontaneous thought, then poetry, wit, hope, virtue, learning, anecdote, and all flock to their aid.
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.
The Creative knows the great beginnings. The Receptive completes the finished things. The Creative is decided and therefore shows to men the easy. The Receptive is yielding and therefore shows to men the simple. Learning is movement from moment to moment.
Real wisdom is not the knowledge of everything, but the knowledge of which things in life are necessary, which are less necessary, and which are completely unnecessary to know.
I think that it's extraordinarily important that we in computer science keep fun in computing. When it started out, it was an awful lot of fun. Of course, the paying customers got shafted every now and then, and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful, error-free perfect use of these machines. I don't think we are. I think we're responsible for stretching them, setting them off in new directions, and keeping fun in the house. I hope the field of computer science never loses its sense of fun.
Learning -the kind of ignorance affected by (and affecting) civilized races, as distinguished from ignorance, the sort of learning incurred by savages. See nonsense.
