Abstract

This essay examines the question of whether language, knowledge, and truth are possible in a world of relativism and flux, developing along a line of comparison between the Cratylus and Theaetetus of Plato on the one hand, and the Zhuangzi 莊子 of the Daoist philosophical tradition on the other. Against Plato’s image of “leaky pots” that symbolizes the impossibility of language in a state of flux, the Zhuangzi introduces “spillover-goblet words” that resist the language of necessity and essence by continually emptying themselves out, only to be filled again with the always contingent. To put the ideas and metaphors of each of these perspectives into conversation, the essay drafts a comparison between two manners of animal classification, with classical taxonomy aligning with Platonism on the one hand, and the evolutionary science of “cladistics”—taxonomy based on ancestry—allying with Daoism on the other. In the end, it is Plato who is left holding his pejorative “leaky pots,” as under conditions of essential change it is putatively unchanging categories themselves that are shown to create the worst problems for knowledge.
