Platonic arguments often have premises of a particular form which is misunderstood. These sentences look like universal generalizations, but in fact involve an implicit qua phrase which makes them a fundamentally different kind of predication. Such general implicit redoubled qua predications (girqps) are not an expression of Plato's proprietary views; they are also very common in everyday discourse. Seeing how they work in Plato can help us to understand them.

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.

This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images but (...) that “consistency should suffice for truth” (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

The question concerning names and things discussed in Cratylus, repeats the old and fundamental philosophical subject of "phusis" and "nomos"; an essential issue which may be considered as the ground for many theories in Greek philosophy. The question In Cratylus is how relates a name to its object or thing to which the name refers. Are names by nature, i.e. is there any necessary relation between a name and its object, or as long as there is a convention, an object (...) could be called by any name. According to Socrates the true nature of anything is tobe found in its idea and not in its perishable material form. Thus the naturally correct name is that which imitates the idea and reveals it.

The non-identity argument at Phaedo 74b–c is among the most studied and disputed arguments in Plato’s dialogues. In the passage, equality is distinguished from perceptible equals insofar as the latter sometimes appear (phainetai) unequal. A long-standing crux is whether the distinction concerns perceptible equals’ merely appearing unequal or actually being so. A fresh approach to the construal of the verb phainomai is taken here and shown to favor the latter view, thereby securing a stronger argument for non-identity.

This dissertation is a defense of a particular theory of the metaphysics of time which I call "accretivism", but which is popularly known in a form usually called the "Growing Block Theory". The goal of a metaphysics of time is to incorporate the various aspects of our temporal experience into a single, comprehensive whole. To this end I delineate five aspects of our ordinary experience of time: 1) The Tensed Aspect, in virtue of which objects are presented to us as (...) past, present, or future; 2) The Transitory Aspect, in virtue of which time passes or "flows"; 3) The Durational Aspect, in virtue of which entities have a certain temporal extent; 4) The Structural Aspect, in virtue of which entities are given as being in temporal relations to one another, and 5) The Differential-Repetitive Aspect, in virtue of which things are different from one time to another, and yet there is a certain recurrence of aspects of our experience form one time to another. I contrast the accretivist picture of time, according to which that which is past and that which is present both have ontological status, but nothing which is future has ontological status, and in which temporal passage consists in the coming-into-being of new entities at the temporal edge of reality marked by the present, with the two dominant theories of time in the contemporary literature: 1) presentism, according to which only that which is present has ontological status, and 2) four-dimensionalism, according to which time is to be understood on analogy with spatial dimensions. Accretivism, I argue, is superior to the other two views in virtue of the fact that it gives full status to both the Structural Aspect of Time, for which the presentist has difficulty accounting, and the Transitory Aspect of Time, for which the four-dimensionalist has difficulty accounting. I then defend the accretivist picture against a variety of objections that might be raised to it. (shrink)

The present paper aims to discuss how the Socratic method oper­ates with Euthyphro inside the Euthyphro. The first part of the article focuses on the character’s description, upon which it moves to analyz­ing the very method itself not only in terms of its argumentative form but also in terms of its psychological and social aspects. Euthyphro is shown to have been a supporter of religion that was entirely incapable of living up to the religious ideals that he so confidently advocated (...) for. Through his portrayal of Socrates’ refutation of Euthyphro, Plato seeks not only to redeem his teacher but also to criticize the then society. When describing the Socratic method, the present paper proposes to view it with a “calm distance” on the grounds of the fact that the distinc­tive feature of the method consists in creating an emotional distance between Socrates and Euthyphro. The purpose of such a strategy is to make Euthyphro realize the weakness of his position and embrace the purification through the socratic elenchos. (shrink)
