"辨"是戰國諸子普遍運用的思想方法,"辯"是諸子普遍運用的話語方式,二者構成戰國公共理性的兩大基石。儒、墨、道、法、名諸家不僅實踐"辨"與"辯",亦對二者皆有論述。諸子均重"辨",對"辯"則態度不一。戰國論辯之風的盛行,催生眾多側重辨析的公共議題。《莊子》雖有齊物之論,但辨察物之分際,疑析概念之確定性,亦是其重要方法。書中雖標舉"辯不若默",然而,論辯亦是其常用的話語方式。命名與析理是《莊子》之辨的展開方式。其命名,是在純思理的世界提出概念,并加以界定。推進式地析分,窮究事物之理,是《莊子》之辨的顯著特征。《莊子》對某些公共議題的辨析,其命名與析理方式,拓展并深化了戰國公共理性的內涵。《莊子》以長于辨析的話語方式將論辯文的藝術水平提升到新的高度。

"Bian 辨 (dialectic)"is the ideological method commonly used by Chinese philosophers during the Warring States Period,"bian 辯 (argument)"is the popular discourse mode for them,these two constituted the two cornerstones of the public reason of the Warring States.Confucians, Mohists, Taoists, Legalists,and Logicians not only practiced "dialectic"and "argument,"but also discussed both.Pre-Qin philosophers all attached importance to "dialectic,"but had different attitudes to"argument."The prevalence of debate during the Warring States Period had spawned many public issues that focus on discrimination.Despite its adjustment of controversies,Zhuangzi still advocates the discerning of objects,and the doubt about and analysis of the certainty of concepts as an important method.Although the book is remarkable for its preach of"not arguing,"argumentation is also a common way that it uses in its discourse.Naming and logic analysis are the development patterns of the dialectic in the Zhuangzi.Its naming is to propose concepts in a purely rational world and define them.Progressive analyses to excavate the truth of things are the distinguishing features of the dialectic in the Zhuangzi.For the analysis of certain public issues in the Zhuangzi,its naming and analytic mode expanded and deepened the connotation of public reason in the Warring States Period.The Zhuangzi raised the artistic level of the argumentative essay to a new height with a discourse that is good at discrimination and analysis.
