《黄帝四经·十大经·观》
能够区别婚姻和贵贱的氏族社会已经形成，其中相互敌对的部落和阶级之间便不断发生战争和争斗，对这种斗争不予伐正社会就不会安定。
刑德皇皇，日月相望，以明其当，而盈屈无匡。
A clan society capable of distinguishing between marriage and nobility has been formed, and wars and conflicts are constantly occurring between hostile tribes and classes; if this struggle is not corrected, society will not be stable.
