The theme of Taoism is one of harmony with nature. Zhuangzi was a central figure in Taoist philosophy. He wrote that people develop different moral attitudes from different natural upbringings, each feeling that his own views are obvious and natural, yet all are blinded by this socialization to their true nature. To Zhuangzi, pre-social desires are relatively few and easy to satisfy, but socialization creates a plethora of desires for "social goods" such as status, reputation, and pride. These conventional values, because of their comparative nature create attitudes of resentment and anger inciting competition and then violence. The way to social order is for people to eliminate these socialized ambitions through open-minded receptivity to all kinds of voices—particularly those who have run afoul of human authority or seem least authoritative. Each has insights. Indeed, in Taoist moral philosophy, perfection may well look like its opposite to us. One theme of Zhuangzi's that links Taoism to the Zen branch of Buddhism is the concept of flow, of losing oneself in activity, particularly the absorption in skilled execution of a highly cultivated way. His most famous example concerns a butcher who carves beef with the focus and absorption of a virtuoso dancer in an elegantly choreographed performance. The height of human satisfaction comes in achieving and exercising such skills with the focus and commitment that gets us "outside ourselves" and into such an intimate connection with our inborn nature.
