Condemnation of Music (Fei Yue)

Mozi's argument is deliberately not an aesthetic judgment. He concedes that bells, drums, and dances are pleasant to hear and beautiful to see. What he rejects is the claim that beauty or pleasure alone justifies an activity. His standard is strictly consequentialist: does the practice benefit the people? Musical performance fails on three counts. It imposes heavy taxes to fund instruments and performers, it diverts able-bodied people from productive labor into entertainment, and it distracts rulers from governance and farmers from their fields. The chapter's opening formula is explicit: the humane person acts only when it benefits people and stops when it does not . Fei Yue is thus a specific application of the broader Jie Yong principle, not a separate doctrine about sound.

The concession is strategic and philosophical. By acknowledging that music is enjoyable, Mozi isolates the disagreement from questions of taste. He is not a philistine who cannot appreciate beauty; he is a critic who denies that aesthetic pleasure has independent moral weight. This distinction separates his position from a crude rejection of art and forces the Confucian opponent onto defensive ground. The argument becomes: given that music is pleasant but costly, what justifies its cost? Mozi's answer is nothing, because the resources consumed by music could be redirected to food, clothing, and shelter for people who lack them. The concession makes the condemnation stronger, not weaker, because it shows the rejection is principled rather than temperamental .

The Mozi originally circulated with many core doctrines in triplets, reflecting competing versions among Mohist factions. For Fei Yue, only Part I survives; Parts II and III are lost. This is significant because the surviving chapter is not the whole Mohist argument but a single version of it. Scholars of the Mozi's textual history, including Watanabe Takashi and Carine Defoort, have analyzed the triplet structure to reconstruct how the text evolved across different Mohist communities. The loss means we cannot compare how different factions framed the anti-music case, whether they emphasized economic harm differently, or what rebuttals they anticipated. Reading Fei Yue as a complete statement of Mohist aesthetics overstates the evidence of a single surviving part .

Xunzi wrote the 'Discourse on Music' (Yue Lun) as a direct rebuttal, structured almost as a point-by-point response to Mozi's arguments. Where Mozi argued that music wastes resources and distracts from production, Xunzi argued that music is rooted in human emotion and cannot be eliminated without distorting human nature. Where Mozi saw music as a drain on social welfare, Xunzi saw it as essential to social harmony, capable of uniting people and refining their moral sensibilities. The debate became one of the defining fault lines between Mohist and Confucian thought. Modern scholarship notes that Xunzi's treatment is more dialectical and culturally sophisticated, distinguishing between legitimate ritual music and corrupting 'deviant sounds,' whereas Mozi's critique operates at a single register of economic utility .

The evidence suggests he understood it well. In Fei Yue, Mozi describes in specific detail the scale of musical performances, the costumes performers wore, and the quality of food they consumed. He mentions Duke Kang of Qi's Wan dance and the resources devoted to it. A 2020 study in Philosophy Compass notes that Mozi's doctrine was 'the conclusion of his philosophical speculation about music, rather than a condemnation led by his dislike or ignorance of music' . This matters for interpretation: Fei Yue is not the rant of someone who does not understand what he is attacking. It is a deliberate argument that a practice he knows to be pleasurable and culturally significant is nonetheless unjustifiable on grounds of public welfare.

Fei Yue is the most visible application of the Jie Yong (Economy of Expenditures) principle, but it is not identical with it. Jie Yong establishes the general rule: expenditure is justified only when it meets a basic need and adds benefit. Fei Yue applies this rule to a specific and highly contested target: musical performance, which Confucians defended as essential to moral cultivation and social order. The relationship is one of premise to conclusion. If Jie Yong is correct, Fei Yue follows for any practice that fails the benefit test. The anti-music chapters also connect to the condemnation of elaborate funerals and prolonged mourning, which Mozi attacked on the same grounds of wasted resources and diverted labor. Together, these doctrines form a coherent program of austerity in consumption and ritual expenditure .
