Hui Shi (; 370âÂÂ310 BCE), or Huizi (; "Master Hui"), was a Chinese philosopher and prime minister of the Wei state during the Warring States period. A representative of the School of Names (Logicians), he 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." He is said to have written a code of laws.
The Yiwenzhi attributes an eponymous one-chapter philosophical work to Hui Shi named Huizi (), 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.
After the death of the Prime Minister of Liang, Shuo Yuan records Hui Shi as rushing at the opportunity to serve the state: <blockquote> æ¢Âç¸æÂ»ï¼ÂæÂ åÂÂ欲ä¹Âæ¢Âï¼Â渡河èÂÂé½墮水ä¸Âï¼Âè¹人æÂÂä¹ÂãÂÂè¹人æÂ°ï¼ÂãÂÂÃ¥ÂÂ欲ä½Âä¹ÂèÂÂé½ä¹Âï¼ÂãÂÂæÂ°ï¼ÂãÂÂæ¢Âç¡ç¸ï¼Âå¾欲å¾Âç¸ä¹ÂãÂÂãÂÂè¹人æÂ°ï¼ÂãÂÂÃ¥ÂÂå± è¹橶ä¹ÂéÂÂèÂÂå°ï¼Âç¡æÂÂÃ¥ÂÂÃ¥ÂÂæÂȍ£ï¼ÂÃ¥ÂÂä½Âè½ç¸æ¢Âä¹Âï¼ÂãÂÂæÂ åÂÂæÂ°ï¼ÂãÂÂÃ¥ÂÂå± èÂÂ楫ä¹ÂéÂÂÃ¥ÂÂå¾ä¸Âå¦ÂÃ¥ÂÂï¼Âè³æÂ¼å®ÂÃ¥ÂÂå®¶ï¼Â堨社稷ï¼ÂÃ¥ÂÂä¹Âæ¯ÂæÂÂï¼ÂèÂÂèÂÂå¦ÂæÂªè¦Âä¹ÂçÂÂè³ãÂÂãÂÂ<br> When the Prime Minister of Liang died, Master Hui desired to serve in the position. He hurriedly tried to cross the river, but fell in and was saved by a boatman. The boatman said: "Sir, just why do you wish to rush?" Hui replied: "Liang has no Prime Minister, so I wish to go and serve as them." The boatman retorted: "If you were to live amongst ships and oars, you would be no match. Without me, you would have died. How, then, could you serve as Prime Minister?" to which Hui said: "Correct: If I were to live amongst oars and boats, I would be no match for you. As for serving the kingdom, this entire nation, compared to me, you are no better than a dog that has neither seen nor heard anything." </blockquote>
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.
Sinologist Hansen took historical commentary on the Zhuangzi as considering Hui Shi's central statement to be that "Heaven, earth and I were born together, the myriad things and I are one." A "poetic expression of the everything concept", Hansen questioned whether a historical Zhuangzi himself would have ever tried to make such a concept. In relation to the Zhuangzi, it is a "classic" or "key" example to understanding the work as "endorsing ideas and then abandoning them."
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 list in the does not, however, explain how Hui Shi argued these theses. Though the theses seem haphazard, and the list lacking in logical structure, Chris Fraser argues that they can be divided into four natural groups:
Another passage from the attributes 21 more paradoxes to Hui Shi and other members of the School of Names, which they are said to have used in their debates. Compared to the Ten Theses listed above, they appear even more absurd and unsolvable:
The last statement in particular, "if from a stick a foot long you every day take the half of it, in a myriad ages it will not be exhausted" is notable for its resemblance to the Dichotomy paradox described by Zeno of Elea. Zeno's paradox takes the example of a runner on a finite race track, arguing that, because runner must reach the halfway point before they can reach the finish line, and the length of the track can be divided into halves infinitely many times, it should be impossible for them to reach the finish line in a finite amount of time. The Mohist canon appears to propose a solution to this paradox by arguing that in moving across a measured length, the distance is not covered in successive fractions of the length, but in one stage.
Due to the lack of surviving works, most of the other paradoxes listed are difficult to interpret.
A dialogue in the Shuo Yuan portrays Hui Shi as having a tendency to overuse analogies ( , which can also be translated as "illustrative examples") with Hui Shi justifying this habit with the claim that communication is impossible without analogies:
A. C. Graham argues that this philosophical position suggests some affinity between Hui Shi and the Mohists, in their shared opinion that "the function of names is to communicate that an object is like the objects one knows by the name"
Most of the other Zhuangzi passages portray Hui Shi (Huizi) as a friendly rival of Zhuangzi (). Hui Shi acts as an intellectual foil who argues the alternative viewpoint, or criticizes the Daoist perspective, often with moments of humor. The best known of the Zhuang-Hui dialogues concerns the subjectivity of happiness.
According to these ancient Daoist stories, Zhuangzi and Hui Shi remained friendly rivals until death.
Chad Hansen (2003:146) interprets this lament as "the loss of a philosophical partnership, of two like-minded but disagreeing intellectual companions engaged in the joys of productive philosophical argument."
