Zhou Dunyi
Founder of Neo-Confucian metaphysics — the 'Supreme Ultimate' and the diagram of cosmic order.
Overview
The pioneer of Neo-Confucian metaphysics, whose short but seminal writings gave the Confucian revival its cosmological foundation. In the 'Diagram of the Supreme Ultimate Explained' he set out how the cosmos unfolds from the Supreme Ultimate (taiji) through yin and yang and the five phases into the myriad things, and how the sage aligns with this order through 'sincerity' (cheng) and stillness. Little recognized in his lifetime, he was canonized by Zhu Xi as the founder of the Cheng-Zhu tradition.
What they supported — and why
The Supreme Ultimate (taiji)
SupportedThe cosmos unfolds from the Supreme Ultimate through the movement and stillness of yin and yang and the five phases into all things.
WhyA single generative principle underlies the ordered production of the world, giving Confucian ethics a cosmological ground.
Sincerity (cheng) as the sage's virtue
SupportedThe sage attains authentic sincerity, aligning perfectly with the cosmic order through stillness and centrality.
WhySince humans are part of the cosmic process, moral perfection is harmonizing the self with the Supreme Ultimate through undivided sincerity.
The unity of cosmology and ethics
SupportedThe moral life is continuous with the structure of the cosmos.
WhyThe same principle that orders nature orders human nature, so self-cultivation is attunement to the universal order.
