This paper considers the use that Plato makes of the Principle of Non-Contradiction in his engagements with eristic refutations. By examining Plato’s use of the principle in his most detailed engagements with eristic—in the Sophist, the discussion of “agonistic” argumentation in the Theaetetus, and especially the Euthydemus—I aim to show that the pressure exerted on Plato by eristic refutations played a crucial role in his development of the PNC, and that the principle provided him with a much more sophisticated means (...) of demarcating philosophical argumentation from eristic than he is generally thought to have. In particular, I argue that Plato’s qualified formulation of the PNC restricts the class of genuine contradictions in such a way that reveals the contradictions that eristics produce through their refutations to be merely apparent and that Plato consistently appeals to his qualified conception of genuine contradiction in his encounters with eristics in order to demonstrate that their refutations are merely apparent. The paper concludes by suggesting that the conception of genuine contradiction afforded by the PNC did not just provide Plato with a way of demarcating genuine from eristic refutations, but also with an answer to substantive philosophical challenges that eristics raised through their refutations.

Anscombe raises a difficulty for the very idea of quotation. Davidson seeks to dissolve this difficulty. But the difficulty is real. And its lesson is that, in quotation, language takes itself as its topic in a non-objectifying manner. The idea of a non-objectifying manner of being a topic is crucial, not merely for understanding quotation, but for understanding the distinctive form of sensory consciousness in which language is perceived.

In recent years a great deal of scholarly and philosophical discussion has been devoted to the interpretation and evaluation of the regress arguments which Parmenides is made to deploy against the theory of Ideas in the first part of the dialogue which takes its name from him. By contrast, scarcely anything has been written about the infinite regress argument which Parmenides presents at the start of the second of the deductions which make up the dialogue's second part. Yet while it (...) may contain less to reward the philosopher than the earlier regresses, it can hardly fail to perplex the scholar. (shrink)

Burnet's text should be emended or repunctuated at three points. At d I we should follow Moreschini and with BT omit Proclus' γε: the unanimous voice of our best manuscripts must be allowed to drown the unreliable Neoplatonist. At e 2, as I shall argue, should be excised. And at e 2–3 the clause is to be attributed to Aristoteles, as Brumbaugh advocates. This attribution gives a better and more typical question and answer sequence, although I can find no other (...) example where Aristoteles ventures sua sponte. (shrink)
