Works

Position

Zhang Zai held that everything consists of qi, the vital stuff of the universe. Dispersed and formless, qi is the Great Void (taixu); when it condenses, things arise, and when they dissolve, they return to it. Nothing comes from nothing or vanishes into nothing – a direct challenge to Buddhist emptiness and Daoist non-being. From this unity follows his ethics: in the Western Inscription he calls Heaven his father and Earth his mother, all people his siblings and all things his companions. His distinction between original nature and the nature shaped by physical endowment was taken up by Zhu Xi and became central to Neo-Confucianism.

Life & context

Zhang Zai was born in 1020; after his father’s early death the family settled in Hengqu in present-day Shaanxi, hence his name “Master Hengqu”. Drawn at first to military affairs, he was directed by the statesman Fan Zhongyan to the Confucian classics and, after long study of Buddhism and Daoism, returned to them. He passed the highest examination in 1057, held minor offices, taught and died in 1077.
