The Doctrine of the Mean

The Doctrine of the Mean is a Confucian classic traditionally attributed to Zisi, the grandson of Confucius. It is a concise treatise on centring the self in unwavering equilibrium, holding to a balanced course between opposing extremes of feeling and conduct.

At its heart stands the concept of cheng, sincerity or integrity, named as the bridge by which the human mind aligns itself with the order of heaven. Sincerity here is more than honesty; it is a wholeness of being in which thought, feeling and action are unified and true to their nature. The equilibrium the text prizes is not mere moderation but a poised inner state from which right response naturally issues, before and after the stirring of emotion.

As one of the Four Books that defined later Confucian education, it transmits the conviction that the cultivated, undivided mind participates in the harmony of the cosmos itself, and that inner authenticity, rather than external rule-following, is the deepest source of moral and even cosmic order.
