Little is known of Han Feizi’s personal life. A member of the ruling family of Han, one of the weaker of the warring states that were in conflict during the 5th–3rd centuries BCE, he studied under the Confucian philosopher Xunzi but deserted him to follow another school of thought more germane to the conditions accompanying the collapse of the feudal system in his time. Finding that his advice to the ruler of his native state went unheeded, he put his ideas into writing. A speech defect is also reputed to have induced his recourse to writing. King Zheng of Qin (a western state)—who became the first emperor of the Qin dynasty in 221 BCE—read and admired some of his essays. When in 234 BCE Zheng launched an attack on Han, the ruler of Han dispatched Han Feizi to negotiate with Qin. Zheng was delighted to receive Han Feizi and probably planned to offer him a high government post. Li Si, the chief minister of Qin and a former schoolmate of Han Feizi’s, presumably afraid that the latter might gain the king’s favour by virtue of superior erudition, had Han Feizi imprisoned on a charge of duplicity. Complying with Li Si’s order to commit death, he drank the poison Li Si sent him, ending his life
