我想那会是一场灾难。外星生命很可能遥遥领先于我们。在我们所处的星球上，先进种族遭遇较为原始人类的历史是不幸的，虽然他们属于同一物种。我觉得我们应当保持低调。

人生最大的幸福是确信我们被爱；因我们自身而被爱，或者更确切地说，尽管我们自身而被爱。

The true sign of intelligence is not knowledge but imagination.

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

"The challenge is to make the impossible look real, and the real look extraordinary."
