"淮南子" by An Liu is a philosophical text compiled before 139 BCE from scholarly debates at Liu An's court. This handbook for enlightened rulers attempts to define perfect socio-political order through synthesizing Taoist, Legalist, Confucian, and Mohist concepts while favoring a less active sovereign. The twenty-one chapters range across religion, history, astronomy, geography, philosophy, and politics, drawing heavily from the Zhuangzi and advocating wuwei nonaction against the Han dynasty's growing centralized government.
