《淮南子·道应训》
君主骄傲就会放肆，放肆纵欲就会穷奢极欲；百姓疲惫就会产生怨恨，怨恨多了就会去动足脑筋谋求摆脱疲惫痛苦，以致会用到谋反的手段。
则恣，恣则极物；罢则怨，怨则极虑。
If the monarch is proud, he will be presumptuous, and if he is presumptuous and lustful, he will be extravagant; If the people are exhausted, there will be resentment, and if there is more resentment, they will use their brains to seek ways to get rid of the exhaustion and pain, so as to resort to rebellion.
