This question seemed to provoke a murmur of sympathetic approval from up and down the table.

Richard continued, “What I mean is that if you really want to understand something, the best way is to try and explain it to someone else. That forces you to sort it out in your mind. And the more slow and dim-witted your pupil, the more you have to break things down into more and more simple ideas. And that’s really the essence of programming. By the time you’ve sorted out a complicated idea into little steps that even a stupid machine can deal with, you’ve learned something about it yourself.”

"Entertaining a notion, like entertaining a baby cousin or entertaining a pack of hyenas, is a dangerous thing to refuse to do. If you refuse to entertain a baby cousin, the baby cousin may get bored and entertain itself by wandering off and falling down a well. If you refuse to entertain a pack of hyenas, they may become restless and entertain themselves by devouring you. But if you refuse to entertain a notion—which is just a fancy way of saying that you refuse to think about a certain idea—you have to be much braver than someone who is merely facing some blood-thirsty animals, or some parents who are upset to find their little darling at the bottom of a well, because nobody knows what an idea will do when it goes off to entertain itself."
