This essay explores a curious point of intersection in the historical pairing of becoming and negation, between two thinkers and two traditions: the Sophist Protagoras of fifth-century BCE Greece and the second-century CE South Asian Buddhist thinker Nāgārjuna. I offer a speculative account of how becoming and negation are linked in Protagoras—speculative because only so much can be deduced from the extant fragments and testimony. I compare that account to the more coherent picture offered by Nāgārjuna—more coherent because a complete (...) account of the logic that links becoming and negation is carefully preserved in the works attributed to Nāgārjuna. While no specific conclusions regarding the bridge that linked India and Greece may be reached, the similarities between these thinkers and the greater coherence of the Buddhist tradition nevertheless offer hypothetical possibilities for reconstructing the larger architecture of the world of sophistic thought that is now lost to us.
