《荀子·儒效》
这是因为孔子用孝悌教化了他们。儒者在朝廷中担任官职，就能使朝政完美；作为老百姓，就能使风俗优良。儒者做臣民时就像这样的啊。秦昭王问： 那么，儒者地位在人之上的时候，又是怎样的呢？ 
儒者在本朝则美政，在下位则美俗，儒之为人下如是矣。 王曰： 然则其为人上何如？ 
This was because Confucius had taught them with filial piety and kindness. When Confucians hold official positions in the court, they can make the government perfect; when they are ordinary people, they can make the customs good. This is what Confucians do as subjects. King Zhao of Qin asked, "Then, what about when the Confucians are in a position above others?"
