Guanzi

The Guanzi, or ‘Book of Master Guan’, is an eclectic work including textual materials dating from the fourth century bc to the first century ad, drawing on themes from Daoism, the science of government, yin–yang and the Five Phases, Legalism, Confucianism, the art of war, economics and the Huang–Lao movement. Its pragmatic outlook is founded on a kind of objective realism that is the signature of the famous fourth-century bc Jixia academy in the principality of Qi. It was this academy that consolidated several different schools of thought.
