The present PhD dissertation aims to examine the relation between modality and change in Aristotle’s metaphysics. -/- On the one hand, Aristotle supports his modal realism (i.e., worldly objects have modal properties - potentialities and essences - that ground the ascriptions of possibility and necessity) by arguing that the rejection of modal realism makes change inexplicable, or, worse, banishes it from the realm of reality. On the other hand, the Stagirite analyses processes by means of modal notions (‘change is the (...) actuality of what is virtual insofar as it is virtual’). In other words: to grasp what change is, one has to resort to the modal idiom of potentialities, while the fact that there is change is indicative of the fact that nature is full of modal properties. -/- Aristotle’s modal and kinetic realism finds a negative in the figure of the Megaric Diodorus Kronus. The polemical situation of Greek philosophy has indeed the dialectical advantage of not opposing the Aristotelian position to a sui generis straw man. Both in its reduction of modal judgements to temporal quantifications and in its dissolution of the reality of the state-of-being-in-motion in favour of a cinematographic view of processes, the philosophical figure of reductionist antirealism embodied by Diodorus constitutes an alternative that takes the opposite view of Aristotle’s realism. -/- The present study is structured as a discussion between these two positions. In the face of Diodorus’ antirealist challenges, Aristotle articulates modal and kinetic considerations: the answers he gives to Diodorus’ puzzles thus provide valuable insight into his metaphysics. Moreover, the examination of Aristotle’s and Diodorus’ metaphysics, because of their insight and originality, will not fail to interest the philosopher concerned with the metaphysical foundations of modern physics, insofar as the entanglement between modalities and processes is nowadays at the core of mechanics (phase spaces, path integrals, etc.).

This selective and opinionated overview of English-language scholarship on the philosophical method(s) of Plato's Socrates discusses whether this Socrates has any expertise or method, how he examines others and why, and how he exhorts others to care about wisdom and the state of their soul.

At a crucial juncture in Plato’s Sophist, when the interlocutors have reached their deepest confusion about being and not-being, the Eleatic Visitor proclaims that there is yet hope. Insofar as they clarify one, he maintains, they will equally clarify the other. But what justifies the Visitor’s seemingly oracular prediction? A new interpretation explains how the Visitor’s hope is in fact warranted by the peculiar aporia they find themselves in. The passage describes a broader pattern of ‘exploring both sides’ that lends (...) insight into Plato’s aporetic method. (shrink)

Plato is commonly considered a metaphysical dualist conceiving of a world of Forms separate from the world of particulars in which we live. This paper explores the motivation for postulating that second world as opposed to making do with the one we have. The main objective is to demonstrate that and how everything, Forms and all, can instead fit into the same world. The approach is exploratory, as there can be no proof in the standard sense. The debate between explaining (...) Plato’s ontology with a single world and requiring a two-world model to make sense of the same thing is typically about scouring the Platonic corpus for evidence and turning to Aristotle for help where we need it. The aim here is to dig deeper than what either of them, or anyone else, has said or implied about the number or worlds, searching instead for any insight that might be gained from the way Forms are supposed to exist versus what we ourselves might understand by existence. Although the paper is, at its most basic level, about the existence of the Forms, the intention is not to prove that they exist, nor to evaluate the proofs and objections already on record, but to consider how they might exist and what follows if they do. Dialogue toward consensus on why we think the Forms exist, and why we think they do not, could perhaps provide a smoother “second sailing” in waters where we have been unable to agree whether they do and where they would if they did.

The article tries to prove that the famous formula "epekeina tês ousias" has to be understood in the sense of being beyond being and not only in the sense of being beyond essence. We make hereby three points: first, since pure textual exegesis of 509b8–10 seems to lead to endless controversy, a formal proof for the metaontological interpretation could be helpful to settle the issue; we try to give such a proof. Second, we offer a corollary of the formal proof, (...) showing that not only self-predication of the form of the Good, but of any form is not possible, that is: no form of F has the form of F. Third, we apply Spinoza’s distinction between an ens imaginarium and a chimaera to Plato’s Idea of the Good. (shrink)

Taking up the controversial issue of the value of the laws of non-ideal cities in Plato’s Statesman, the paper argues for a modified version of the traditional interpretation, as defended against Christopher Rowe’s influential criticism. The paper agrees with the traditional view that the established laws of non-ideal cities are assumed to be good laws and that the Eleatic Stranger’s justification for this assumption can be found in 300b. But it also argues that this defence of the traditional interpretation must (...) be based on a revised understanding of the role of legislation in the Stranger’s conception of ideal rule. The unique contribution of the expert to good government consists in his distinctive ability to judge what is appropriate in each case, not in his work as legislator, which, on closer inspection, turns out to be based on the very same ancestral traditions that the second best city must resort to.

Au début du Sophiste, Socrate demande au visiteur éléate ce qu’ont pensé des genres philosophe, sophiste et politique, « ceux » qui sont de ce lieu-là ». L’article a pour but d’éclairer cette dernière expression et en particulier son mot clef « topos ». Il est montré que les significations de ce terme, dans son contexte, sont multiples et que cette diversité, loin d’apporter la confusion, permet au contraire et précisément d’ouvrir les diverses perspectives du dialogue. At the beginning of (...) the Sophist, Socrates asks the Eleatic Visitor how the three kinds Philosopher, Sophist and Statesman, have been understood by “those who are in this place”. The purpose of this paper is to enlighten this periphrasis and specially its key-word “topos”. We have showed that, in its context, this word has four main meanings, and that this diversity, far from causing confusion, opens up the dialogue to various perspectives. (shrink)

A commentary on the Symposium as a challenge and a gift to Athens. I begin with a reflection on three dates: 416 bce, the date of Agathon’s victory party, c. 400, the approximate date of Apollodorus’ retelling of the party, and c. 375, the approximate date of the ‘publication’ of the dialogue, and I argue that Plato reminds his contemporary Athens both of its great poetic and legal and scientific traditions and of the historical fact that the way late fourth (...) century Athens appropriated them in some way led to the city’s demise at the turn of the century; thus the dialogue is Plato’s challenge to his contemporary Athens to recognize and overcome its flawed relation to its cultural resources. Heard in this way, the key moments are Aristophanes’ implied critique of Pausanias and Eryximachus and Socrates’ implied critique of Aristophanes and Agathon. Proceeding by a close reading, I argue that Plato exposes, for those moved to rise to his challenge, the failure of his great predecessors to conceive the divine in a way that, worthy of the height and otherness divinity requires, can provide substantive orientation for the burgeoning new reason that animates the city’s culture.

Within the framework of the discussion about the existence of a spokesman in the Platonic dialogues, we look, in the first part, into the possible transfer of this spokesman’s function from Socrates to the Eleatic Stranger, identifying the contact and divergence points between both characters. In the second part, we try to show that this transfer has a dramatic staging at the beginning of the Sophist dialogue, where Socrates makes a demand that enables the Stranger to demonstrate his genuine philosophical (...) condition.

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.

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)

Despite Diotima’s irresistible virtues and attractiveness across the millennia, she spells trouble for philosophy. It is not her fault that she has been misunderstood, nor is it Plato’s. Rather, I suspect, each era has made of Diotima what it desired her to be. Her malleability is related to the assumption that Plato invented her, that she is a mere literary fiction, licensing the imagination to do what it will. In the first part of my paper, I argue against three contemporary (...) ‘majority views’ about Diotima that I regard as false. The first is that we can be certain she is fictional;1 a second is that Diotima is our best evidence for Plato’s feminism; the third, that she is Plato’s mouthpiece for the higher mysteries in the Symposium. After I have set aside what I regard as false, I proceed in the second half of my paper to develop Diotima’s positive contribution to philosophical psychology, her naturalistic account of the psyche as mortal, unified, and developmental. Whether the view Plato assigns to her is one that he held I do not pretend to know; but it is a powerful, defensible, and coherent view that inspired positive aspects of Freudian psychology in the twentieth century. Freud’s insight, in fact, makes clear how erōs can be developed in relation to the bad as well as the good. (shrink)

Sind platonische Ideen oder Formen wirklich in dem Sinn als „eingestaltig“ konzipiert, dass sie nicht aus Teilen bestehen können? Ganz und gar nicht! Christoph Hochholzer zeigt, dass die Relation von Teil und Ganzem einer Form neben der Relation der Teilhabe an Formen zu den zentralen Grundannahmen der Ideenlehre gehört. Von diesem Befund ausgehend, entwickelt die detaillierte Textanalyse eine ganz neuartige Interpretation des Sophistes. Der eleatische Fremde, der Sokrates in dem Spätdialog als Gesprächsführer ablöst, präsentiert demnach eine ausgereifte Variante von Platons (...) Philosophie, mit deren Hilfe er unterschiedlichste Fragen präzise beantwortet: Was ist die Bedeutung von „... ist seiend“ oder „... ist verschieden von...“? Gibt es Nicht-Seiendes? Können auch Formen an Formen teilhaben? Was genau sind eigentlich Sophisten und wieso kann Sokrates ihnen nicht helfen? Die Untersuchung beinhaltet eine streng logische Rekonstruktion des Textes ohne die literarische Form des Dialogs und seine Stellung in Platons Gesamtwerk zu vernachlässigen. Sie bietet eine neue Übersetzung und einen philologisch gründlichen Kommentar. Daraus werden eine Vielzahl von neuen Positionen zu klassischen Forschungsfragen, wie die nach der Selbstprädikation oder dem Mythos, entwickelt. (shrink)

Passage 228a7-8 of Plato’s Sophist has been the object of a broad debate by reason of a number of subtle interpretative problems. The present work attempts to take stock of this passage and to put forward a satisfying solution from both a philological and an exegetic perspective. I seek to show that the reading cited by Galen and adopted in the editions of the Sophist (τὴν τοῦ φύσει συγγενοῦς ἔκ τινος διαφθορᾶς διαφοράν) cannot be preferred to the variant found in (...) the manuscripts of the dialogue (τὴν τοῦ φύσει συγγενοῦς ἔκ τινος διαφορᾶς διαφθοράν). As for the interpretation, both readings stand out as problematic. I propose to reconsider the interpretation of the syntagma τοῦ φύσει συγγενοῦς and to translate it as “the natural kinship” rather than as “what is naturally kindred”. The paper continues with an analysis of the role played by kinship in Plato’s philosophy, showing how its sundering can be identified with stasis. (shrink)
