This article considers the function and value of the mythos in Plato's Statesman. As first, I recall the context of the story and its function within the framework of diairetic inquiry about the definition of the real politician. Secondly, I point out that the formulation of the myth is based on a series of traditional stories to which a historical-reconstructive method is applied. I then highlight the ways of reasoning used by the characters in order to reconstruct a rational and (...) plausible account from the mythical tradition. Finally, I try to show that the story, even though it cannot reach the truth of the most stable objects of knowledge, displays a certain degree of plausibility, based on the internal coherence, on the respect of a series of principles admitted as true and, eventually, on its correspondence with the mythical tradition.

The problem of negative truth is the problem of how, if everything in the world is positive, we can speak truly about the world using negative propositions. A prominent solution is to explain negation in terms of a primitive notion of metaphysical incompatibility. I argue that if this account is correct, then minimal logic is the correct logic. The negation of a proposition A is characterised as the minimal incompatible of A composed of it and the logical constant ¬. A (...) rule based account of the meanings of logical constants that appeals to the notion of incompatibility in the introduction rule for negation ensures the existence and uniqueness of the negation of every proposition. But it endows the negation operator with no more formal properties than those it has in minimal logic. (shrink)

Despite intensive exegetical work, Plato’s description of dialectic in the Sophist still raises many questions. Through a close reading of this passage that contextualizes it in the general organisation of the Sophist, this paper provides answers to these questions. After presenting the difficult text, I contend that the “vowel-kinds” are necessary conditions for the blending of kinds. Then, I interpret the “cause of divisions” mentioned by the Stranger as the kinds responsible of the dichotomous division in the first half of (...) the dialogue. In the next part, I show that 235d5-e2 does not describe a procedure of “meta-divison” as some commentators have it, but that it describes the method of division itself. Finally, I connect the difficulty and the obscurity of the passage to the fact that dialectic is the supreme science and I explain why dialectic is the science of free men. (shrink)

This paper transposes for evaluation in relation to the concerns of Plato’s Politicus a claim developed by Verity Harte in the context of his Philebus, that ‘external imposition of a practical aim would in some way corrupt paideutic [philosophical] knowledge’. I argue that the Politicus provides a case for which the Philebus distinction may not allow: ruling, or statecraft, as embodying a form of knowledge that can be answerable to practical norms in a way that does not necessarily subordinate or (...) corrupt its epistemic norms. I argue further that while Harte shows that the Philebus develops a view of the ethical value for a knower in being a knower, the Politicus for its part does not develop any view of the ethical value for a knower in being a ruler.

The cosmological myth in Plato’sStatesmanhas generated several longstanding scholarly disputes, among them a controversy concerning the number and nature of the cosmic rotation cycles that it depicts. According to the standard interpretation, there are two cycles of rotation: west-to-east rotation occurs during the age of Cronus, and east-to-west rotation occurs during the age of Zeus, which is also our present era. Recent readings have challenged this two-cycle interpretation, arguing that the period of rotation opposed to our own is governed neither (...) by Cronus nor by Zeus, but is instead a separate rotational cycle during which chaos reigns before a divine ruler reestablishes control. We introduce a new constraint on any plausible interpretation of the myth. According to theCorrespondence Principle, changes in fundamental cyclical processes that shape the way of life on earth (mode of generation, growth, aging, and mode of death) occur if and only if there is a change in the direction of cosmic rotation. We use theCorrespondence Principleto defend a version of the standard two-cycle interpretation. (shrink)

It has become commonplace in introductions to Indian philosophy to construe Plato’s discussion of forms (εἶδος/ἰδέα) and the treatment in Nyāya and Vaiśeṣika of universals ( sāmānya/jāti ) as addressing the same philosophical issue, albeit in somewhat different ways. While such a comparison of the similarities and differences has interest and value as an initial reconnaissance of what each says about common properties, an examination of the roles that universals play in the rest of their philosophical enquiries vitiates this commonplace. (...) This paper draws upon the primary texts to identify the following metaphysical, epistemological, semantic and soteriological roles that universals play in the philosophy of Plato and of Nyāya and Vaiśeṣika: Metaphysical: causal of the existence of x Metaphysical: constitutive of the identity/essence of x Epistemological: cognitively causal (i.e. of the cognition of one over many) Epistemological: epistemically causal (i.e. of knowledge of x) Semantic: necessary condition of speech and reason Epistemological: vindicatory of induction (Nyāya only) Metaphysical: explanatory of causation (Nyāya only) Soteriological: cathartic contemplation (Plato only) These roles provide us with motivations or reasons to believe that universals exist. As we examine these motivations, we find pressures mounting against our assimilating Platonic forms and the universals of Nyāya and Vaiśeṣika in the discourse about common properties. It is especially when we appreciate the utterly different contribution that universals make in securing our highest welfare that we realize how Plato and the two sister schools are not so much talking somewhat differently about the same thing, but talking somewhat similarly about different things. This better understanding of this difference in these philosophies opens a route for our better understanding of their unique contributions in the ongoing dialogue of philosophy. (shrink)

In this paper I defend a new reading of the final argument of the Gigantomachia passage of Plato’s Sophist (249b5–249c9), according to which it is an argument for a two-kind ontology, based on the distinction between the changing beings and the unchanging beings. This argument, I urge, is addressed not only to Platonists but to all philosophers – with one exception. My reading is based on the claim that this argument does not rely on the view that nous requires unchangeable (...) objects – what I call the traditional reading – but on the view that nous itself is unchanging. The difference between the traditional reading and my reading is that on the former, Plato’s argument relies on a distinctive epistemological assumption, whereas on the latter, Plato’s argument is free from any such commitments. If the argument of this paper is along the right lines, then this implies that this argument has a much more far-reaching scope than critics have usually assumed. It also invites us to reconsider Plato’s approach to the question of being in the Sophist. (shrink)

Hackforth and Menn make a strong case for the identity of nous and the demiurge in Plato, but I argue that it does not hold in the case of the Philebus, where the demiurge is kept in the background, and the world-soul is in fact the referent in the passage assigning nous to the class of cause as governor of the universe. In the Statesman, the world-soul had had to own the problem of natural catastrophe, and I suggest that in (...) the Philebus the role and functions of the world-soul are enhanced in an attempt to make it the basis for a solution to that problem.

Two readings of the much-discussed περιτροπή argument of "Theaetetus" 170c-171c have dominated the literature. One I call "the relativity reading". On this reading, the argument fails by ignoratio elenchi because it "carelessly" omits "the qualifications 'true for so-and-so' which [Protagoras'] theory insists on" (Bostock 1988: 90). The other reading I call "the many-worlds interpretation". On this view, Plato's argument succeeds in showing that "Protagoras' position becomes utterly self-contradictory" because "he claims that everyone lives in his own relativistic world, yet at (...) the same time he is forced by that very claim to admit that no one does" (Burnyeat 1976b: 48). I discuss and criticise both readings, and present a third, according to which the point of the argument is, very roughly, that Protagoras is committed to equating truth and truth-for, and so, further, to their intersubstitutability. This further commitment proves fatal to his argument. (shrink)

In this paper I discuss the dialogues between 'Protagoras', Theodorus and Socrates in "Theaetetus" 161-171 and emphasise the importance for this passage of a dilemma which refutation is shown to pose for relativism at 161e-162a. I argue that the two speeches delivered on Protagoras' behalf contain material that is deeply Socratic and suggest that this feature of the speeches should be interpreted as part of Plato's philosophical case against relativism, reflecting the relativist's own inability to defend his theory from attempts (...) to refute it. I then discuss Theodorus' role in the refutation of Protagoras and argue that his voice is needed to get relativism disproved in the self-refutation argument of 171a-c. I conclude with a brief discussion of the image of Protagoras at 171d. (shrink)

In this paper I offer a reading of one of Plato's later works, the Sophist, that reveals it to be informed by principles comparable on the face of it with those that have emerged recently in the field of critical thinking. As a development of the famous Socratic method of his teacher, I argue, Plato deployed his own pedagogical method, a ‘mid‐wifely’ or ‘maieutic’ method, in the Sophist. In contrast to the Socratic method, the sole aim of this method is (...) not to disabuse the reader or learner of her false opinions. Rather, its purpose is to supply her with the skills and dispositions as well as the claims and counter‐claims she needs to critically evaluate a view, and so facilitate knowledge acquisition, for herself. But the text does not merely teach critical thinking in this indirect manner. One of the strategies its author employed was to encourage the reader/learner to consider under what conditions a claim or idea would be false. To the extent that it achieves this, the Sophist provides both a model and an application of that particular kind of critical thinking in the learning environment that Jonathan Baron has described as ‘active open‐mindedness’.
