《论衡·卷九·问孔篇》
孔子说： 没有智，怎么算得上仁呢？ 这是指子文曾举荐楚子玉接替自己的职位去讨伐宋国，结果用一百辆战车的兵力被打败，而且丧了他的全部人马，不智到这种地步，怎么算得上是仁呢？
子文曾举楚子玉代己位而伐宋，以百乘败而丧其众，不知如此，安得为仁？
Confucius said: “How can someone be considered benevolent when they lack intelligence? This refers to the time when Ziwen recommended Chu Ziyu to succeed him in his position in order to attack the State of Song. In the end, Ziyu was defeated with a force of one hundred chariots and lost his entire army. How can someone so unwise be considered benevolent?”
