This paper argues for a possible-worlds interpretation of the arguments marshalled by Socrates against Protagoras in Plato’s Theaetetus. Specifically, it reads Protagoras’ position as implying a limited form of modal realism, and evaluates both the self-refutation sequence at 170a–71d and the Future Argument at 177c–9c on the basis of this reading. It emerges that Socrates’ project is only partly successful: while the three main arguments of the self-refutation sequence force Protagoras into ever more awkward and metaphysically top-heavy positions, and the (...) Future Argument is psychologically compelling, these arguments do not force a collapse of the relativist position. Protagoras can still defend himself, though the cost is high. (shrink)

The topic of degrees of being in Aristotle is almost universally ignored. A very few scholars do discuss the topic or make use of it in passing. This situation mightbe explained by a scholarly consensus that Aristotle did have a doctrine ofdegrees of being, but this doctrine is too uninteresting to be worth much discussion. Conversation with a number of scholars from several countries has convinced me, however, that a rather different consensus lies behind the current silence. It turnsout that (...) many experts in the subject deny that Aristotle believed in degrees of being.No one, to my knowledge, has defended this denial in print. But the reason forsilence is not that the topic is dull, but that it is scandalous. Both defenders andopponents of the view that Aristotle had a doctrine of degrees of being tend, in conversation, to find the topic embarrassing. Our contemporary metaphysical prejudices areso opposed to degrees of being that people find themselves unable to make anysense of such a doctrine. As a result, one group of scholars is embarrassed on Aristotle's behalf at the suggestion that he might have held such a senseless doctrine.Another group, less sure of where the philosophical truth lies, finds itself in theinterpretative embarrassment of being unable to explain and motivate the doctrine. So bothgroups avoid the subject. (shrink)

Scholarship on ancient skepticism has undergone a remarkable renaissance in the last three decades. Specialists in ancient philosophy have explored the complex history of the Greco‐Roman skeptical traditions and discussed difficult philological and exegetical issues. But they have also assessed the philosophical significance of the various ancient skeptical outlooks. In this first paper, I provide a general presentation of this area of study, while in the two subsequent articles I will focus on some of the topics that have been the (...) object of much attention in the recent literature on ancient skepticism.
