What is Taiji (太极)?
The term taiji (太极) first appears in the Great Commentary (系辞传) of the Yijing, where the text says that "in Change there is the Supreme Ultimate" and that it generates the Two Modes — the paired poles of yin and yang. The concept was given its most systematic form by the Song-dynasty Neo-Confucian Zhou Dunyi (周敦颐) in the Explanation of the Diagram of the Supreme Ultimate (太极图说). Zhou's cosmology begins with Nonpolar (wuji 无极), from which Taiji emerges; Taiji moves and stills, and from that movement and stillness come yin and yang; the interaction of the two produces the five agents and finally the ten thousand things (万物). Because the diagram is not a picture of a physical object but a map of how order emerges, it shaped Neo-Confucian metaphysics for centuries. The shared name should not be confused with taiji quan (太极拳), the martial art, which borrows the term for its circling, balanced movement.
无极而太极。太极动而生阳，动极而静，静而生阴。

Key Takeaways
- 太极 (tàijí) means "supreme ultimate," the undifferentiated whole that precedes and gives rise to yin and yang (阴阳).
- The phrase comes from the Great Commentary (系辞) of the Yijing: "In Change there is the Supreme Ultimate; it generates the Two Modes."
- Song-dynasty philosopher Zhou Dunyi (周敦颐) formalized the sequence in his Explanation of the Diagram of the Supreme Ultimate (太极图说): Wuji → Taiji → yin-yang → the ten thousand things.
- Chinese: 太极 (Taiji).

Frequently Asked Questions
What is Taiji in Chinese Philosophy?
太极 (tàijí) means "supreme ultimate," the undifferentiated whole that precedes and gives rise to yin and yang (阴阳). The term first appears in the Great Commentary (系辞) of the Yijing, and it names the single root from which the paired poles of reality unfold.
What does 太极 mean?
The characters 太 (tài, "great") and 极 (jí, "pole, extreme") together mean "supreme ultimate." In the Yijing's Great Commentary the phrase describes the undivided starting point of change, the one from which the Two Modes of yin and yang are generated. It is the name for the whole before any of its parts are separated out.
How is Taiji related to Yin Yang, Change (I Ching)?
Taiji is the conceptual bridge between the metaphysics of the Yijing and the paired categories of yin and yang. Zhou Dunyi's diagram lays out the chain from Nonpolar (Wuji) to Taiji to yin-yang to the ten thousand things, so that the I Ching's doctrine of change has a systematic cosmological foundation rather than a merely practical one.
Why is Taiji important?
Taiji became the organizing principle of Neo-Confucian metaphysics. After Zhou Dunyi used it to explain the origin of order in the universe, later thinkers such as the brothers Cheng Hao and Cheng Yi and Zhu Xi built their schools of metaphysics around it. Its name also lives on in taiji quan (太极拳), the martial art that turns the same idea of balanced movement into bodily practice.
