 Understanding the Zhuangzi is made more difficult by the huge differences not only in the philosophical context, but in the pervasive metaphors that structure and focus discussions of norms of behavior in the Chinese vs Indo-European classical traditions. His positions invite comparisons with modern metaethical naturalism but he does not focus them with concepts linked to grammatical sentences such as “laws” or “rules” (sentences in all form) or “facts” (sentence-sized chunks of reality) or “properties (realities corresponding to sentence predicates).” Zhuangzi used the traditional 道 dàopath metaphor together with the technical terminology developed in Mohism  of shì-fēithis-not that, biàndistinction and kěpermissible.
