This article explicates Xunzi's three types of cognitive delusions in Xunzi's Zhengming Pian. The followings are my conclusions: first, general names such as “a white horse,” “a horse,” “a thief,” and “a man” are thought of as proper nouns because the classic Chinese theory of language concerned pragmatics rather than semantics. Second, classic Chinese epistemology does not address conceptual (logical) knowledge or knowledge based on argumentation distinguished from the art of description. Third, Gongsun Long believes in an extreme form of one-name-one-thingism. Fourth, Neo-Moists' theory of inference is based on intensional contexts. Fifth, Hui Shi's position presupposes the art of knowing objects before any verbal expression and suggests the arbitrariness in the expressions of known objects. Sixth, Xunzi's logic and semantics are extensional.
