不能言说之事，必须保持沉默。
Whereof one cannot speak, thereof one must be silent.
一个好的机械师不仅仅是一个会锉锤的人，而是能够创新和完善的人。
生活教会了我思考，但思考却没有教会我生活。
Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues. The story of civilization is the story of what happened on the banks.
