This paper presents an interpretation of Gongsun Long’s white horse paradox. The Chinese sentence he uses to state his main thesis (Bai ma fei ma) has two potential readings: (a) The white horses are not horses. (b) The white horses are not the horses. Although (a) gives the usual and correct reading of the sentence, according to the interpretation, Gongsun Long takes it to state (b). He gives good arguments for (b) while taking them to establish (a) as well, for he fails to distinguish between the two different theses. In presenting this interpretation, the paper gives an account of the function of numeral classifiers and discusses the semantics of count nouns in languages with no grammatical number system, including classical Chinese and classifier languages (e.g., contemporary Chinese).
