Xunzi 荀子 provided naturalistic answers to questions regarding human sociality and our characteristic “groupishness” (qun 羣). Central to his theories were so-called “social divisions and righteousness” (fenyi 分義), which can be interpreted as a uniquely human package of “cultural technology” produced via cultural evolution to suppress intragroup conflict stemming from what Xunzi calls “the mind of covetous comparison” (liangyi zhi xin 兩疑之心). For Xunzi, fenyi is the uniquely human attribute which kickstarts a salutary causal chain which facilitates prosociality and the (...) upscaling of cooperation, and ultimately results in human ecological dominance. This essay will argue that an incipient form of cultural evolution is discoverable in the Xunzi, and moreover that a solution to the problem of the origin of the “ritual and righteousness” (liyi 禮義) cultural package derives neatly from the incipient cultural evolution of the Xunzi. That is to say, while this solution is not explicitly adduced in the Xunzi, it is nonetheless consistent with Xunzian ideas and is an improvement on the much-lambasted solution Xunzi actually gives, according to which “the former kings hated … chaos, and so they established rituals and righteousness.”.
