Zou Yan

Who was Zou Yan?

Zou Yan was the representative thinker of the Yin and Yang during the Hundred Schools of Thought era in Chinese philosophy. Zou Yan was a noted scholar of the Jixia Academy in the state of Qi. Joseph Needham, a British sinologist, describes Zou as "The real founder of all Chinese scientific thought." His teachings combined and systematized two current theories during the Warring States period: Yin-Yang and the Five Elements/Phases.

All of Zou Yan's writings were lost and are only known through quotations in early Chinese texts. The best information comes from his brief biography in the Records of the Grand Historian by Sima Qian. It describes him as a polymath who came from the coastal state of Qi, where he was a member of the state-sponsored Jixia Academy. Needham writes:

So he examined deeply into the phenomena of the increase and decrease of the Yin and the Yang, and wrote essays totaling more than 100,000 words about their strange permutations, and about the cycles of the great sages from beginning to end.

First he spoke about modern times, and from this he went back to the time of. The scholars all studied his arts. ... He began by classifying China's notable mountains, great rivers and connecting valleys; its birds and beasts; the fruitfulness of its water and soils, and its rare products; and from this extended his survey to what is beyond the seas, and men are unable to observe. Then starting from the time of the separation of the Heavens and the Earth, and coming down, he made citations of the revolutions and transmutations of the Five Powers, arranging them until each found its proper place and was confirmed. maintained that what the Confucians called the "Middle Kingdom" holds a place in the whole world of but one part in eighty-one. … Princes, dukes and great officials, when they first witnessed his arts, fearfully transformed themselves, but later were unable to practice them.
