《论衡·卷二十一·死伪篇》
志士遗憾正义的事业没有成功，学士遗憾学问上很多方面造诣不高，农夫遗憾种了地没有积储粮食，商人遗憾货物钱财没有增值，当官的人遗憾官位没能达到顶点，勇武的人遗憾武艺没有达到最高水平。
志士则恨义事未立，学士则恨问多不及，农夫则恨耕未畜谷，商人则恨货财未殖，仕者则恨官位未极，勇者则恨材未优。
A gentleman regrets that his cause of justice has not been successful, a scholar regrets that he has not learnt much, a farmer regrets that he has not stored up grain after cultivating his fields, a businessman regrets that his goods and money have not increased in value, a government official regrets that he has not reached the highest rank, and a courageous person regrets that his martial arts have not reached the highest level.
