Jin Xin II · 孟子 7B.22
Passage 22
高子曰:「禹之聲,尚文王之聲。」孟子曰:「何以言之?」曰:「以追蠡。」曰:「是奚足哉?城門之軌,兩馬之力與?」
The disciple Gao said, 'The music of Yu was better than that of king Wen.' Mencius observed, 'On what ground do you say so?' And the other replied, 'Because at the pivot the knob of Yu's bells is nearly worn through.' Mencius said, 'How can that be a sufficient proof? Are the ruts at the gate of a city made by a single two-horsed chariot?'
