《论衡·卷八·儒增篇》
公叔文子确实是该说才说，有高兴事才笑、合乎礼义才接受财物，人们传说称赞他；至于说他不说话、不笑、不要财物、那是庸人说的竟然把事情过分夸张了。
夫公叔文子实时言、时笑、义取，人传说称之；言其不言、不笑、不取也，俗言竟增之也。
Gongshu Wenzi really only spoke when he had something to say, smiled only when he was happy and accepted money only when it was in accordance with the rules of propriety. People spoke of him in high praise; those who claimed that he did not speak or smile or refuse money were ordinary people who had grossly exaggerated the matter.
