He cherishes his old knowledge, and is continually acquiring new. He exerts an honest, generous earnestness, in the esteem and practice of all propriety. Thus, when occupying a high situation he is not proud, and in a low situation he is not insubordinate. When the kingdom is well governed, he is sure by his words to rise; and when it is ill governed, he is sure by his silence to command forbearance to himself.

昔者天子有爭臣七人，雖無道，不失其天下...父有爭子，則身不陷於不義。故當不義，則子不可以不爭於父，臣不可以不爭於君。故當不義則爭之，從父之令，又焉得為孝乎？
