《吕氏春秋·览·审分览》
因此，诸侯丧失了爵位，那么天下就会混乱，大夫没有等级，那么朝廷就会混乱；妻妾不加区分，那么家庭就会混乱，嫡子庶子没有区别，那么宗族就会混乱。
是故诸侯失位则天下乱，大夫无等则朝廷乱，妻妾不分则家室乱，适孽无别则宗族乱。
Accordingly, if the vassals lose their ranks, then the empire will fall into disorder; if the officials don't have their ranks, then the court will fall into disorder; if concubines and wives make no distinction to each other, then families will fall into disorder; if the legitimate son and the illegitimate son make no distinction, then the clan will fall into disorder.
