《管子·匡君大匡》
小白说： 管仲虽然不得行其智，但毕竟不是没有智；召忽虽不得国人支持，他的党羽还是可以图害我们的。 
小白曰： 夫虽不得行其知，岂且不有焉乎？召忽虽不得众，其及岂不足以图我哉？ 
Xiaobai said: Although Guan Zhong is not allowed to exercise his intelligence, he is not without intelligence. Although Zhaohu does not have the support of the people, his partisans can still plot against us.
