《论衡·卷一·累害篇》
人的才能有高有低，不可能等同。同时一起去做官，才能高的得到荣升，才能低的就惭愧怨恨，就毁谤伤害朋友的品行，这是二累。
人才高下，不能钧同，同时并进，高者得荣，下者惭恚，毁伤其行，二累也。
Men's abilities are great or small, and they cannot possibly be equal. When they serve as officials together, the more capable ones rise to honour, while the less capable are filled with shame and resentment, and this again produces calumny and recrimination, and this is a second evil.
