Samuel C. Rickless [To appear in Ancient Philosophy] Abstract: Plato’s Sophist is puzzling inasmuch as it presents us with seven completely different definitions of sophistry. Though not all seven definitions could be accurate, Plato never explicitly indicates which of the definitions is mistaken. Recently, Kenneth Sayre, Mary Louise Gill, and Noburu Notomi have proposed a clever solution to this puzzle. In this paper I explain why the Sayre-Gill-Notomi solution is mistaken, and suggest a better solution.
