Abstract: The pre-Qin period was the prime time for the study of debate,with the theory of“Debates with Victory”of the late Mohist school as the representative.However,Zhuang Zi went against this theory and put forward“Debates with No Victory”.The dispute between Zhuang Zi and the late Mohist school on“Debates with Victory”and“Debates with No Victory”had multiple theoretical connotations.Adopting the Western pragmatism and the traditional coincidental theory of truth as the framework,the article tries to analyze both the advantages and disadvantages of the two sides,so as to rediscover and reevaluate the deep meanings of Zhuang Zi's“Debates with No Victory”from a new point of view.
