Hui Shi (; 370–310 BCE), or Huizi (; "Master Hui"), was a Chinese philosopher during the Warring States period. He was a representative of the School of Names (Logicians), and is famous for ten paradoxes about the relativity of time and space, for instance, "I set off for Yue (southeastern China) today and came there yesterday." Philosophy The Yiwenzhi attributes a philosophical work to Hui Shi, but it is no longer extant, probably being lost prior to the Tang dynasty. For this reason, knowledge of his philosophy relies on the several Chinese classic texts that refer to him, including the Zhan Guo Ce, Lüshi Chunqiu, Han Feizi, Xunzi, and most frequently, the Zhuangzi. Nine Zhuangzi chapters mention Hui Shi, calling him "Huizi" 26 times and "Hui Shi" 9 times. "Under Heaven" (chapter 33), which summarizes Warring States philosophies, contains all of the latter 9 references by name. Belonging to the School of Names, Hui Shi's philosophy is characterised by arguments centred around the relativity of the concepts of sameness ( ) and difference ( ). He frequently used analogies and paradoxes to convey his arguments. The Ten Theses The final chapter of the Zhuangzi, ( 'Under Heaven') claims that Hui Shi held ten main opinions, referred to as "The Ten Theses" or "The Ten Paradoxes", and lists them as follows: The largest thing has nothing beyond it; it is called the One of largeness. The smallest thing has nothing within it; it is called the One of smallness. That which has no thickness cannot be piled up; yet it is a thousand li in dimension. Heaven is as low as earth; mountains and marshes are on the same level. The sun at noon is the sun setting. The thing born is the thing dying. Great similarities are different from little similarities; these are called the little similarities and differences. The ten thousand things are all similar and are all different; these are called the great similarities and differences. The southern region has no limit and yet has a limit. I set off for Yueh today and came there yesterday. Linked rings can be separated. I know the center of the world: it is north of Yen and south of Yueh. Let love embrace the ten thousand things; Heaven and earth are a single body. The list in the does not, however, explain how Hui Shi argued these theses. Though the
