You’ve got to have models in your head. And you’ve got to array your experience—both vicarious and direct—on this latticework of models.

You’ve got to hang experience on a latticework of models in your mind.

The world is like a chessboard， whereon we may see a living knight， but we cannot see a living chess.

概率既由我们观察的性质决定，也由我们的理性观念决定。
