Canon 5: Mutual Suspicion Among Rivals
When the situation is one of mutual suspicion among rival powers, disorder is born from it; therefore, a wise ruler is cautious about it. Thus, in Jin, Li Ji killed Crown Prince Shensheng; in Zheng, the consort used poison; in Wei, Zhou Yu killed his lord Wan; Prince Gen seized Eastern Zhou; Prince Zhi was greatly favored, and Shang Chen indeed launched a rebellion; Yan Sui and Han Wei quarreled, and Marquis Ai was indeed assassinated; Tian Chang, Kan Zhi, Dai Huan, and Huang Xi were rivals, and the lords of Song and Duke Jian of Qi were killed. The explanation lies in Hu Tu’s reference to the “Two Favorites,” and Zheng Zhao’s reply of “Not Yet Born.”
Note
This Han Feizi passage examines “Mutual Suspicion Among Rivals”. Citing multiple Spring‑and‑Autumn power‑struggle cases, it argues blurred hierarchies breed deadly political turmoil, so wise rulers must enforce clear rank distinctions.
Li Ji and Crown Prince Shensheng of Jin:
Li Ji (骊姬) was a favored concubine of Duke Xian of Jin (晋献公). Her status rivaled that of the principal wife. She schemed to have her own son Xiqi (奚齐) replace Shensheng (太子申生) as crown prince. She framed Shensheng before the duke, who ordered the prince’s death. Shensheng committed suicide.
This is one of the most famous succession crises in Chinese history, and it resulted in the State of Jin having no royal clansmen. The royal house’s power was systematically weakened, paving the way for powerful non‑surnamed ministers to expand their influence and ultimately led to the fragmentation of Jin into three states (Han, Zhao, Wei) a century later.
The Poisoned Lord of Zheng:
The ruler of Zheng had already established a crown prince, but a favored concubine wanted her own son to become heir. The principal consort, fearing for her son’s position, poisoned the ruler. This illustrates the reverse scenario: when the “established” side strikes first to preserve the status quo.
Zhou Yu of Wei:
Zhou Yu (州吁), a prince of Wei whose power and prestige rivaled that of the ruler himself. The common people and officials feared his authority. He eventually assassinated his brother, Duke Huan of Wei (卫桓公, personal name Wan), and seized the throne. This is a classic case of a prince whose elevated status created a “Mutual Suspicion Among Rivals” that could only be resolved through violence.
Prince Gen and the Split of Zhou:
The Zhou royal domain had already been reduced to a tiny territory. Prince Gen (公子根), the younger brother of the Zhou ruler, was deeply favored. After the ruler’s death, Prince Gen rebelled and seized the eastern portion of the domain. The Zhou royal house was permanently split into Eastern Zhou and Western Zhou, with the Zhou Son of Heaven reduced to a mere figurehead residing within the Eastern Zhou domain.
Shang Chen and Prince Zhi of Chu:
King Cheng of Chu (楚成王) had established Shang Chen (商臣) as crown prince, but later favored Prince Zhi (王子职) and considered replacing Shang Chen. Shang Chen, upon learning of this through a clever ruse devised by his tutor Pan Chong (潘崇), launched a preemptive coup. He surrounded the palace with guards and forced his father to commit suicide. When King Cheng begged for time to cook a bear’s paw (a dish requiring long preparation, thus buying time for counterattack), Shang Chen refused. This is one of the most dramatic patricides in Chinese history.
Yan Sui and Han Wei of Han:
Han Wei (韩廆) served as chancellor under Marquis Ai of Han (韩哀侯), while Yan Sui (严遂) was another minister who enjoyed the marquis’s special favor. The two became bitter rivals. Yan Sui hired an assassin to kill Han Wei at court. When Han Wei was attacked, he threw himself around the marquis for protection – and the assassin’s blade struck both men, killing the marquis as well.
Tian Chang and Kan Zhi of Qi:
Tian Chang (田常) was the chancellor of Qi, while Kan Zhi (阚止) was a minister favored by Duke Jian of Qi (齐简公). The two were irreconcilable enemies. Tian Chang used the opportunity to distribute private largesse, win popular support, and eventually assassinate Duke Jian, seizing control of Qi. The Tian clan would later replace the Jiang clan as rulers of Qi entirely.
Dai Huan and Huang Xi of Song:
Dai Huan (戴驩) served as Grand Administrator of Song, while Huang Xi (皇喜) enjoyed the lord of Song’s special favor. They engaged in a deadly power struggle, and Huang Xi ultimately killed the lord of Song and seized power.
Hu Tu’s “Two Favorites”:
Hu Tu (狐突) was a minister of Jin. He stated: “When the ruler favors those within the inner chambers (concubines), the crown prince is in danger; when the ruler favors those outside the court (new ministers), the chancellor is in danger.” This elegantly identifies the two sources of “Mutual Suspicion Among Rivals” – internal (harem politics) and external (court politics).
Zheng Zhao’s “Not Yet Born”:
When the ruler of Zheng asked Zheng Zhao about the status of the crown prince, Zheng Zhao replied: “The crown prince has not yet been born.” The ruler was confused – the prince had already been formally established. Zheng Zhao explained: “Although the prince has been established, your fondness for beauty never ends. When a favored concubine bears a son, you will surely love him, and loving him, you will surely want to make him heir. Therefore I say the crown prince has not yet been truly born.” This is one of the most penetrating observations in Chinese political thought: a crown prince is only as secure as the ruler’s self-restraint.
Mutual Suspicion Among Rivals / Structural Ambiguity:
It refers to a political situation in which multiple power centers exist at comparable levels, creating structural ambiguity about who holds ultimate authority. In Legalist theory, this is the most dangerous condition a state can face – not because any individual is evil, but because the system itself generates a prisoner’s dilemma in which preemptive violence becomes the rational choice for all parties.
Internal Struggle:
The full title of this canon is “mutual suspicion leading to internal struggle”. Han Fei argues that internal struggle is not caused by individual malice but by structural conditions. When the ruler fails to establish clear hierarchies, the system itself produces violence.
Prisoner’s Dilemma:
Although Han Fei did not use this modern game-theoretic term, his analysis of “Mutual Suspicion Among Rivals” is essentially a description of the prisoner’s dilemma applied to politics. Each rival faction faces the choice: strike first (and possibly survive) or wait (and possibly be destroyed). The rational choice for each individual is to strike first, even though mutual restraint would be better for all.
Hierarchical Distinction:
A core Legalist principle. Han Fei argues that the ruler must maintain strict, unambiguous hierarchies – the queen above concubines, the crown prince above other princes, the chancellor above other ministers. Any blurring of these distinctions creates “Mutual Suspicion Among Rivals” and inevitably leads to disorder.
经五参疑
参疑之势，乱之所由生也，故明主慎之。是以晋骊姬杀太子申生，而郑夫人用毒药，卫州吁杀其君完，公子根取东周，王子职甚有宠而商臣果作乱，严遂、韩廆争而哀侯果遇贼，田常、阚止、戴驩、皇喜敌而宋君、简公杀。其说在狐突之称”二好”，与郑昭之对”未生”也。
