叶公问孔子于子路，子路不对。子曰，女奚不曰，其为人也，发愤忘食，乐以忘忧，不知老之将至云尔。
白话导读
叶公向子路问起孔子是怎样的人，子路没有回答。孔子说：你为什么不这样说呢：他这个人啊，发愤用功起来连吃饭都忘了，快乐起来把一切忧愁都忘了，连自己快要老了都不知道，如此而已。
James Legge 英译
1. The Duke of Sheh asked Tsze-lu about Confucius, and Tsze-lu did not answer him. 2. The Master said, "Why did you not say to him,—He is simply a man, who in his eager pursuit (of knowledge) forgets his food, who in the joy of its attainment forgets his sorrows, and who does not perceive that old age is coming on?"
