《汉书·传·张冯汲郑传》
而汲黯时常诋毁儒术，当面指责公孙弘等一味内挟欺诈外饰智巧，以迎合主上的意图，取得主上的欢心；刀笔吏专门片面深析法律条文巧妙诋毁，陷害人入法网，并因此而自认为有功。
而黯常毁儒，面触弘等徒怀诈饰智以阿人主取容，而刀笔之吏专深文巧诋，陷人于罔，以自为功。
Ji An often criticized Confucianism and accused Gongsun Hong and others of deceit, using their intelligence to please the emperor and win his favor; the clerks who handled legal documents specialized in analyzing the laws in a biased manner, framing people and sending them to prison, and thereby believing that they were doing something good.
