《荀子·乐论》
混乱又争夺，那就会兵力衰弱、城池被侵犯，敌国就会来危害了。像这样，那末老百姓就不会安居在自己的住处，就不会喜欢自己的家乡，也不会使自己的君主满足了。
乐姚冶以险，则民流僈鄙贱矣；流僈则乱，鄙贱则争；乱争则兵弱城犯，敌国危之如是，则百姓不安其处，不乐其乡，不足其上矣。
If there is chaos and fighting, the military will be weak, the cities will be attacked, and the enemy will invade. In this way, the people will not be at peace in their dwellings, will not love their hometown, and will not satisfy their sovereign.
