《论衡·卷二十六·实知篇》
纣王制作了象牙筷子而箕子发出哀叹，鲁国用偶人随葬而孔子为此发出慨叹，这是由制作象牙筷子预见到纣王要吃龙肝的祸患，由用偶人随葬预见到用人殉葬的灾祸。
纣作象箸而箕子讥，鲁以偶人葬而孔子叹，缘象箸见龙干之患，偶人睹殉葬之祸也。
King Zhou made ivory chopsticks, and Ji Zi sighed; the State of Lu used puppets to be buried with them, and Confucius sighed. This is a disaster to see the king's liver in the future by making ivory chopsticks, and to see the disaster of human sacrifice in the future by using puppets for burial.
