  This entry skips over the puzzles about being, which aim to show that we are in as much confusion about being as we are about not-being, a situation that gives the Stranger hope: to the extent that he and Theaetetus get clear about being or not-being, they will get clear about the other as well (Sophist 250e–251a) (Owen 1971, 229–31, calls this claim the “Parity Assumption.”)[2]
