《论衡·卷二十八·正说篇》
尧就是功德浩大无比老百姓简直不知道怎样来称赞他；舜就是天下安定欢乐；禹继承尧舜的帝业，使道德崇高浩大，老百姓不知怎样来称赞他；殷就是使道德适中；周武王就是使功德周密无所不至。
尧则荡荡民无能名；舜则天下虞乐；禹承二帝之业，使道尚荡荡，民无能名；殷则道得中；周武则功德无不至。
Yao's virtues were so great that the common people did not know how to praise him; Shun brought peace and happiness to the world; Yu inherited the great cause of Yao and Shun, making morality lofty and vast, and the people did not know how to praise him; Yin brought moderation to morality; King Wu of Zhou made his virtues comprehensive and meticulous.
