《礼记·王制》
行为诈伪而又顽固不化、言辞虚伪而又巧言利舌、所学陷入异端而又自以为博闻、言辞谬庚而讲得冠冕堂皇，以此蛊惑人心者，杀掉。
行伪而坚，言伪而辩，学非而博，顺非而泽，以疑众，杀。
Punish with death anyone who is fraudulent and obstinate, glib and cunning, whose learning borders on heresy, but who claims to be knowledgeable, and whose misleading words flow from his lips like a torrent of water, to poison the minds of the people.
