记忆是一个奇怪的东西，它的运作方式并不像我们想象的那样。我们习惯于把它想象成相机或录音机，但它完全不是那样的。它更像是一个画家，根据自己的规则添加或删除元素。
"Memory is a strange thing, it doesn't work like I thought it did. We are so used to thinking of it as a camera or a tape recorder, but it's not like that at all. It's more like a painter, who adds and subtracts elements according to his own rules."
国家一定要有直言进谏的臣子，上级必须有敢于提出反对意见的下级，议论国政的人不停止，各种不同政见的人相互辩论，才可以长久保存国家，使国家兴盛强大。也就是说言论自由是民众的基本权利，每个人都可以提出不同的政见，民众有平等参与政治的权利。
The stream of thought is the stream of life solving its problems.
