Between having had two undergraduate courses on the Platonic dialogues —one on ancient Greek philosophy, one on Plato’s dialogues, specifically, and having read the remainder of the dialogues on my own—, I had never encountered the “Unitarianism versus Revisionism” debate, until taking (currently) a graduate course on Plato’s theory of knowledge. Not just that, I had no inkling or intuition that there might be such a debate. In examining why, with a mind to Theaetetus, I felt it difficult to buy the Revisionist position, and so it seems blog-post worthy to explain.
