《三国志·蜀书·邓张宗杨传》
邓芝回答说： 天无二日国无二君，如果吞并魏朝之后，大王也不知道天命顾念的是谁，为君者就各自发扬自己的德行，臣子各自尽忠职守，身为将领就拿起其武器，战争这才开始。 孙权大笑说： 您确实很诚实！ 
芝对曰： 夫天无二日，土无二王，如并魏之后，大王未深识天命者也，君各茂其德，臣各尽其忠，将提枹鼓，则战争方始耳。 权大笑曰： 君之诚款，乃当尔邪！ 
<number>. Deng Zhi said: There is only one sun in the sky and one king in a country, if Wei is annexed, my lord doesn't know who Heaven will give the orders to, so the rulers will show their own virtues, the officials will give their loyalty, the generals will start their wars, and then it's the start of the war. Sun Quan laughed and said: You are honest indeed!
