 Among Warring States texts, only two show any familiarity with the details of Hui Shi’s and Gongsun Long’s theses. (The “Under Heaven” book of the Zhuangzi, the major source for our discussion of Hui Shi, dates probably from the first few decades of the Han dynasty.) One is the Xunzi, which as we saw ascribes a list of seven paradoxes to Hui Shi and Deng Xi, as well as alluding elsewhere (22.3) to the white horse sophism. The other is the famous “Discourse on Equalizing Things,” Book 2 of the Zhuangzi, though the text does not attribute the theses to Hui Shi or Gongsun Long by name. “Equalizing Things” is critical of the disputers’ ideas and in one passage explicitly criticizes Hui  Shi.[24]  But it also praises his intelligence and is not downright hostile toward him, as Xunzi is.
