The great synthesizer of the Legalist school and the most systematic and pragmatic political philosopher of the late Warring States period. He fused Shang Yang's "Fa" (written law), Shen Buhai's "Shu" (the ruler's techniques of managing ministers), and Shen Dao's "Shi" (power and authority) into a comprehensive theory of monarchical autocracy. His historical evolutionism—"when the age changes, affairs change; when affairs change, preparations must change"—rejected the Confucian retrograde orientation of "modeling on former kings," advocating reform suited to the times. His doctrine of "using law as instruction and officials as teachers" provided the theoretical foundation and operational blueprint for the Qin dynasty's centralized unification, profoundly shaping Chinese political institutions for the following two millennia.
Personal name Fei, a prince of the state of Han in the late Warring States period, approximately 280–233 BCE. Born into the Han royal family, he had a severe stutter and was poor at speech but brilliant in writing. He studied under Xunzi alongside Li Si, who admitted his own abilities were inferior to Han Fei's. Seeing his state of Han weak and repeatedly invaded by powerful Qin, with an incompetent king, Han Fei repeatedly memorialized the King of Han urging reform and strengthening, but was ignored. In frustration, he withdrew to write, producing the famous essays "The Isolated," "The Five Vermin," and "The Difficulty of Persuasion." When these writings reached the state of Qin, King Zheng (the future First Emperor) read them and exclaimed: "If I could meet this man and associate with him, I would die without regret." Li Si informed him it was the work of Han Fei; the king dispatched troops against Han to demand him. Han Fei was sent as envoy to Qin, where the king was delighted but did not trust him. Li Si and Yao Jia slandered him, saying "Han Fei will ultimately serve Han, not Qin." Han Fei was imprisoned. Li Si sent poison; Han Fei wished to defend himself but had no avenue, and was forced to take his own life in the prison of Yunyang. His tragic end itself confirms his own thesis of "the difficulty of persuasion"—the extreme danger of lobbying a ruler.
Han Feizi's philosophy is grounded in cold Hobbesian human-nature realism and utilitarianism. Ontologically, he denies any transcendent moral heavenly principle—"Dao" and "li" are merely the objective laws governing the operation of things, with no prior moral attributes. In mind-nature theory, he inherits Xunzi's "nature is evil" and pushes it to an extreme: human selfishness and profit-seeking are natural facts; rulers, ministers, fathers, sons, and spouses all treat each other with "calculating minds." There is no genuine benevolence from the heart, so moral governance is mere fantasy. In political philosophy, the tripartite synthesis of "law, technique, and power" (fa shu shi) is his core: "Law" is publicly promulgated written code applied equally to all—"the law does not favor the noble; the plumb line does not bend for the crooked." "Technique" is the ruler's secretly held method of controlling ministers—"technique is hidden in the breast." "Power" is the authority and position the ruler must firmly grasp—"power is the means to overcome the multitude." In historical philosophy, he holds that "when the world changes, affairs change; when affairs change, preparations must change," opposing the Confucian reverence for antiquity: "In high antiquity they competed in virtue; in the middle age they vied in wisdom; today they contend in strength." Different eras require different governance.
"The law does not favor the noble; the plumb line does not bend for the crooked. When the world changes, affairs change; when affairs change, preparations must change. — Han Feizi, "On Degrees" and "The Five Vermin""
Han Feizi's "rule by law" is a powerful instrument of control wielded by the ruler. Where lies the boundary between this and the modern "rule of law" that advocates checking public power and equality before the law?
Han Fei takes publicly promulgated "law" as fundamental, advocating the institutional objectivity of "the law does not favor the noble." Machiavelli takes hidden "power politics" as core, emphasizing the ruler's personal adaptability and deception. Law versus stratagem—but both share a cold realist disposition.
Is the foundation of governance institutionalized law or the ruler's personal stratagem? Between Han Fei's rule by law and Machiavelli's power politics, which achieves more lasting political stability?
Both Han Fei and Hobbes proceed from the assumption that human nature is evil, advocating absolute sovereignty to suppress the chaos of the state of nature. But Han Fei uses "law" as the instrument, while Hobbes uses "covenant" as the social basis. The sources of legitimacy are entirely different—one from monarchical authority, the other from the people's delegation.
Does the legitimacy of absolute power come from the ruler's force or from the people's covenant? Both Han Fei and Hobbes advocate strong power, but does their different foundation determine the fate of two political civilizations?
