Xi Deng

Deng Xi (鄧析, c. 545–501 BCE) was a philosopher, rhetorician, and official of the state of Zheng. He is associated with the School of Names, a tradition known for its interest in language, logic, debate, and the relationship between words and reality.

He was celebrated—and criticized—for arguing both sides of a case with remarkable skill. Deng Xi also developed a legal code written on bamboo, known as the “Bamboo Law,” and is remembered as an early advocate of making laws public and applying them to the realities of society rather than relying solely on inherited ritual traditions.

Deng Xi was executed in 501 BCE by Si Chuan, a later ruler of Zheng, who nevertheless adopted his penal code. Later records attribute writings to him under the title Deng Xi Zi, though the surviving text and its authorship remain debated.
