"The past is always with us, and it shapes who we are."

 消灭一个错误，其贡献等同于、有时甚至超过建立一条新真理或新事实。

As Will Rogers would have said, "There is no such thing as a free variable."

The worst enemy of life, freedom and the common decencies is total anarchy; their second worst enemy is total power.

经验只是我们给错误起的名字。

Success is not final, failure is not fatal: It is the courage to continue that counts.

权力不会腐蚀。恐惧会腐蚀……也许是对失去权力的恐惧。
