《韩非子·外储说左下》
范文子喜欢直说，他父亲武子用手杖打他： 直说的人不被人所宽容，不被宽容就危及自身。不只是危及自身，还将危及父亲。 
范文子喜直言，武子击之以杖： 夫直议者不为人所容，无所容则危身，非徒危身，又将危父。 
Fan Wenzi always spoke his mind. His father Wuzi hit him with a stick and said to him, "Those who speak their minds do not please others, and if they do not please others, they put themselves in danger. And it's not just themselves they put in danger; they also put their father in danger."
