Lock up your libraries if you like; but there is no gate, no lock, no bolt that you can set upon the freedom of my mind.
你可以锁上你的图书馆；但对我的思想自由，你无法设置任何门闩、锁或插销。
The ideas I had about supernatural beings came to me the same way that my mathematical ideas did. So I took them seriously.
可持续发展不是选择，而是负责任企业的唯一出路。
Never forget what you are, for surely the world will not. Make it your strength. Then it can never be your weakness. Armor yourself in it, and it will never be used to hurt you.
Victory:a matter of staying power.
