《论衡·卷十九·恢国篇》
难道是周武王因为父亲周文王曾被囚禁在羑里而对纣王怨恨太深的缘故吗？纣王作为君王而囚禁他的臣下周文王，纣王的倒行逆施，比起秦国消灭周朝和王莽毒死汉平帝来，哪个罪轻，哪个罪重呢？
岂以羑里之恨哉？以人君拘人臣，其逆孰与秦夺周国，莽鸩平帝也？
Is it because King Wu of Zhou hated King Zhou too much because his father King Wen of Zhou was once imprisoned in Xi'an? King Zhou imprisoned his minister King Wen of Zhou as a king. King Zhou's wrongdoings are compared with the State of Qin destroying the Zhou Dynasty and Wang Mang poisoning Emperor Ping of Han. Which sin is lighter and which is heavier?
