Hui Shi

Hui Shi (370 to 310 BCE), also called Huizi or Master Hui, was a Chinese philosopher of the Warring States period and a representative of the School of Names, or Logicians. According to the Lushi Chunqiu he served as prime minister of the state of Wei, also called Liang, and is said to have written a code of laws. He is famous for ten paradoxes about the relativity of time and space, such as the claim that he set off for Yue today and arrived there yesterday, and his philosophy centres on the relativity of sameness and difference, often argued through analogy. His own book, the Huizi, is lost, so what survives of his thought comes from texts that mention him, above all the Zhuangzi, whose final chapter, Under Heaven, lists his ten theses.
