Contra Twelve Philosophers (Fei Shi Er Zi)

The chapter's argument is diagnostic: the twelve thinkers are condemned not for abstract philosophical error but for producing doctrines that 'make the world confused about where right and wrong, order and chaos reside' . Xunzi groups them into six pairs, each pair representing a distinct failure of governance. What he rejects is any teaching that undermines the ritual hierarchy and unified standards he believes are necessary for social order. The chapter's constructive content is implicit: by showing what the twelve deny—gradations of rank, the authority of the sage-kings, the necessity of ritual restraint—Xunzi sketches his own Way. The critique is thus a mirror held up to his positive political philosophy .

The six pairs are: (1) Tuo Xiao and Wei Mou, charged with indulging emotions and behaving like beasts; (2) Chen Zhong and Shi Qiu, charged with repressing emotions and seeking isolation to appear superior; (3) Mo Di and Song Xing, charged with promoting utility and frugality while ignoring social distinctions; (4) Shen Dao and Tian Pian, charged with lacking a classical norm for the state; (5) Hui Shi and Deng Xi, charged with devising devious doctrines; and (6) Zisi and Meng Ke, charged with transmitting fabricated traditions attributed to Confucius . Notably, Xunzi does not label these men by 'schools'—that terminology came later—but targets their specific doctrines and behaviors .

This inclusion is the chapter's most provocative feature. Xunzi accuses Zisi and Mencius of 'presumptuously creating doctrines' and attributing their own inventions to Confucius, thereby misleading later generations . The charge is that they fabricated a tradition, not that they departed from Confucianism outright. For Xunzi, the Mencian claim that human nature is good and that moral cultivation consists in nourishing innate sprouts is precisely the kind of doctrine that removes the necessity for external ritual discipline and the corrective authority of teachers. By placing Mencius alongside Mohists and Sophists, Xunzi signals that the greatest threat to the Confucian Way may come from within, from those who claim to defend it while corrupting its foundations.

The Fei Shi Er Zi functions as a negative image of Xunzi's positive program. Against the first pair's indulgence, it implies the necessity of ritual restraint. Against the second pair's isolation, it implies social integration and clear distinctions. Against Mozi's frugality and leveling, it implies graded hierarchy and the legitimacy of rank. Against the sophists' verbal ingenuity, it implies fixed standards of naming and judgment . The chapter's conclusion makes the positive program explicit: the benevolent person should model himself on Shun and Yu in institutional structure and on Confucius and Zigong in principle, striving to 'put an end to the doctrines of these twelve figures' so that 'the harms in the world will be eliminated' .

The chapter is Xunzi 6 in the received text. The standard complete English translation is John Knoblock's Xunzi: A Translation and Study of the Complete Works, Volume 1 (Stanford, 1988), which renders the title as 'Contra Twelve Philosophers' . Eric Hutton's more recent Xunzi: The Complete Text (Princeton, 2014) is an accessible one-volume alternative. The Chinese Text Project provides a bilingual edition . A significant interpretive issue concerns the identity of several figures: Tuo Xiao's life is unknown, and the historicity of some attributions is uncertain. The chapter's authorship is generally accepted as Xunzi's own, though some scholars note stylistic and doctrinal tensions with other chapters .
