《论衡·卷二·率性篇》
听到伯夷的品格，贪恋的人会廉洁，怯懦的人会立志；听到柳下惠的品格，刻薄的人会厚道，庸俗的人会宽容。
闻伯夷之风者，贪夫廉而懦夫有立志；闻柳下惠之风者，薄夫敦而鄙夫宽。
Hearing of Boyi's character, the greedy person will become honest, and the timid person will become ambitious. Hearing of Liu Xiaohui's character, the mean person will become honest, and the vulgar person will become tolerant.
