This paper deals with an important strand of nihilistic arguments to be found in the works of two philosophers who have so far never been studied comparatively: the sophist Gorgias and the Buddhist monk Nāgārjuna. After having reconstructed Gorgias' moves in the first section of On What is Not (Sections 1-4), the paper shows how the nihilist arguments Gorgias uses mostly feature, under a new light, in the philosophy of emptiness developed by Nāgārjuna (Sections 5-8). The paper ends with a (...) hermeneutical suggestion: that is, to replace traditional ‘sceptical’ interpretations of Gorgias and Nāgārjuna with an alternative one, which takes them as possibly committed to nihilism.
