The many definitions of sophistry at the beginning of Plato’s Sophist have puzzled scholars just as much as they puzzled the dialogue’s main speakers: the Visitor from Elea and Theaetetus. The aim of this paper is to give an account of that puzzlement. This puzzlement, it is argued, stems not from a logical or epistemological problem, but from the metaphysical problem that, given the multiplicity of accounts, the interlocutors do not know what the sophist essentially is. It transpires that, in (...) order to properly account for this puzzle, one must jettison the traditional view of Plato’s method of division, on which divisions must be exclusive and mark out relations of essential predication. It is then shown on independent grounds that, although Platonic division in the Sophist must express predication relations and be transitive, it need not be dichotomous, exclusive, or express relations of essential predication. Once the requirements of exclusivity and essential predication are dropped, it is possible to make sense of the reasons that the Visitor from Elea and Theaetetus are puzzled. Moreover, with this in hand, it is possible to see Plato making an important methodological point in the dialogue: division on its own without any norms does not necessarily lead to the discovery of essences.

In this second installment on the Theaetetus, I discuss Theaetetus' second and third definitions of knowledge, namely, ‘true judgment’ and then ‘true judgment with the addition of an account’. I offer a brief description of Socrates' intricate examination of these suggestions, concentrating especially on the discussion of false judgment and that of the so-called ‘Dream Theory’. I then proceed to map different lines of interpretation for these passages that have been offered by scholars writing in the last 40 years.

ABSTRACTThis article aims at understanding the functions of the forms of Being and the Other in Plato's Sophist. In contrast with a linguistic interpretation purporting to draw a distinction between uses of the verb “to be,” I shed light on the ontological role ascribed to “the great genus” in the interweaving of forms. Focusing on the vowel analogy, I argue that the roles of Being and the Other respectively are that of a connector and a separator actualizing the participations and (...) the differences between the forms. The outcome of this analysis is to offer an explanation of the dialectical methods described in that dialogue in a rather obscure, abstract way; the much-debated question of self-predication can be settled without recourse to selfparticipation.

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)

Resumen Propongo interpretar la inversión de Deleuze del platonismo como la creación de conceptos nuevos a partir de elementos teóricos tomados de la filosofía del propio Platón. En primer lugar, consideraré el origen nietzscheano de la inversión y su interpretación heideggeriana, de la cual, creo, Deleuze se vale para ciertos argumentos. En segundo lugar, me basaré en la hipótesis de Francis Wolff e Isabelle Ginoux de que la filosofía platónica tiene un carácter ambiguo en la obra deleuziana para analizar esa (...) ambigüedad en términos de la pregunta por los elementos positivos que Deleuze rescata para la creación de una nueva imagen del pensamiento.I propose to interpret the deleuzian reversal of Platonism as the creation of new concepts from the same elements the French philosopher extracts from Plato’s thought. To justify this I will first examine the nietzschean origins of the reversal as well as Heidegger’s interpretation of it, which I think inspires Deleuze. Then, based on the works of Francis Wolff and Isabelle Ginoux, I will explore the ambiguity of Plato’s role in Deleuze’s philosophy, especially in those elements he recovers and exploits to build a new image of thought.

In Plato’s Statesman, the Eleatic Stranger leads Socrates the Younger and their audience through an analysis of the statesman in the service of the interlocutors’ becoming “more capable in dialectic regarding all things”. In this way, the dialectical exercise in the text is both intrinsically and instrumentally valuable, as it yields a philosophically rigorous account of statesmanship and exhibits a method of dialectical inquiry. After the series of bifurcatory divisions in the Sophist and early Statesman, the Stranger changes to a (...) non-bifurcatory method of dividing to account for the statesman, but does not explain the reason for this change. I argue that the change is prepared by the elements discussed in the digression from 277a2 to 287b2. Here the Stranger makes use of four concepts that are crucial for understanding this change: the notion of paradigm, the paradigms of care and the weaver, and the notion of due measure. I claim that the notion of paradigm clarifies the nature of dialectical inquiry, care and weaving act as paradigms appropriate to dialectical practice, and an account of due measure offers insight into the constitutive ratios that govern the structuring of kinds pursued through dialectical inquiry. I suggest that the non-bifurcatory method is intended to articulate knowledge in the strictest sense, or knowledge of the forms, presenting a method of inquiry into being and its structure that will foster the turning of the soul from things to forms that Socrates describes in the Republic.

El objetivo de este artículo consiste en mostrar que no basta con cuestionar las opiniones establecidas y con argumentar dialécticamente para adoptar una actitud filosófica; es preciso además matar al Padre, es decir asumir un nombre propio, un lugar de enunciación que conlleva una colisión más o menos polémica con los pensadores con quienes dialogamos. Si Sócrates representa la figura del tábano que cuestiona y persuade, el Extranjero del Sofista representa la figura del parricida. Sostendré entonces que la actitud filosófica (...) solo puede explicarse en toda su amplitud y profundidad a partir de estas dos figuras. Asimismo, mostraré que la institución académica tiende a privilegiar la figura del tábano en detrimento de la figura del parricida. (shrink)

This paper defends an interpretation of Plato, Soph. 259c7–d7, which describes a distinction between genuine and pretender forms of ‘examination’ or ‘refutation’ (ἔλεγχος). The passage speaks to a need, throughout the dialogue, to differentiate the truly philosophical method from the merely eristic method. But its contribution has been obscured by the appearance of a textual problem at 259c7–8. As a result, scholars have largely not recognized that the Eleatic Stranger recommends accepting contrary predication as a condition of genuine refutation. After (...) reviewing various proposals to change the text, the paper defends this reading. Finally, the paper turns to the methodological significance of accepting contrary predication. The dialogue depicts contrary predication as an instance of a class of statements that compel the soul's disbelief. Soph. 259c7–d7 suggests that these kinds of statements are a crossroad: one can either reject them and turn to eristic discourse or accept them and practise genuine refutation. The paper reflects on what this indicates about Plato's meditations on contradiction and philosophy. (shrink)

This paper defends Plotinus’ reading ofSophist248e-249d as an expression of the togetherness or unity-in-duality of intellect and intelligible being. Throughout the dialogues Plato consistently presents knowledge as a togetherness of knower and known, expressing this through the myth of recollection and through metaphors of grasping, eating, and sexual union. He indicates that an intelligible paradigm is in the thought that apprehends it, and regularly regards the forms not as extrinsic “objects” but as the contents of living intelligence. A meticulous reading (...) ofSophist248e-249d shows that the “motion” attributed to intelligible being is not temporal change but the activity of intellectual apprehension. Aristotle’s doctrines of knowledge as identity of intellect and the intelligible, and of divine intellect as thinking itself, are therefore in continuity with Plato, and Plotinus’ doctrine of intellect and being is continuous with both Plato and Aristotle.

Contextualização e identificação dos processos dialéticos em alguns diálogos de Platão. Constituição da dialética platônica, a partir da dialética socrática e eleática.

At 252e1 to 253c9 in Plato’s Sophist, the Eleatic Visitor explains why philosophy is a science. Like the art of grammar, philosophical knowledge corresponds to a generic structure of discrete kinds and is acquired by systematic analysis of how these kinds intermingle. In the literature, the Visitor’s science is either understood as an expression of a mature and authentic platonic metaphysics, or as a sophisticated illusion staged to illustrate the seductive lure of sophistic deception. By showing how the Visitor’s account (...) of the science of philosophy is just as comprehensive, phantasmatic and self-concealing as the art of sophistry identified at the dialogue’s outset, this paper argues in favor of the latter view.

At Sophist 253d-e the Eleatic Visitor offers a notoriously obscure description of the fields of one-and-many that the dialectician “adequately discerns.” Against the readings of Stenzel, Cornford, Sayre, and Gomez-Lobo, I propose an interpretation of that passage that takes into account the trilogy of Theaetetus-Sophist-Statesman as its context. The key steps are to respond to the irony of Socrates’ refutations at the end of the Theaetetus by reinterpreting the last two senses of logos as directed to forms and to recognize (...) their correlation with the two different modes of diairesis practiced by the Eleatic Visitor. These steps position us to recognize in the Visitor’s remarks at Sophist 253d-e a schematic description of the two kinds of eidetic field that the two modes of diairesis trace. (shrink)

rotágoras de Abdera, conhecido sofista da Grécia antiga, é compreendido em seus dizeres no decorrer da história da filosofia principalmente devido às contribuições de Platão. O ateniense não apenas dedicou uma obra com seu nome, como também apresentou sua famosa tese do homem-medida no diálogo Teeteto, contribuindo imensamente para elucidar questões importantes sobre seu relativismo. O quão seria pertinente afirmar que é possível saber na íntegra o que queria dizer Protágoras nesse fragmento quando seguimos apenas os testemunhos de Platão. No (...) presente trabalho, iremos propor algumas interpretações dos fragmentos de Protágoras de Abdera com a finalidade de percebermos se há divergências com a interpretação platônica, acima de tudo sobre o fragmento do homem-medida. Traremos, para a análise de Protágoras, o livro de Edward Schiappa, Protagoras and Logos, fazendo as devidas considerações sobre suas conclusões, para, ao final da pesquisa, nos posicionar devidamente diante do que Platão, de fato concordou e acertou sobre o homem-medida.

The standard interpretation of "Theaetetus" 152-160 has Plato attribute to Protagoras a relativistic theory of truth and existence. It is argued here that in fact the individuals of Protagorean worlds are inter-Personal. (thus the Protagorean theory has public objects, but private truth). Also, a new interpretation is offered of Plato's use of heraclitean flux to model relativism. The philosophical and semantic consequences of the interpretation are explored.

Embora a noção de crença e sua relação com a ação sejam bastante discutidas na literatura sobre o ceticismo, a descrença e as mudanças de crenças são pouco examinadas, apesar de bastante relevantes para a análise das crenças. Em que condições mudamos de crenças, abandonamos crenças anteriores e adotamos novas crenças? Examinaremos dois exemplos significativos e muito influentes na tradição que podem nos esclarecer quanto a isso: Agostinho e Martinho Lutero.

The purpose of this paper is to reassess some mathematical examples in Plato’s dialogues which at a first glance may appear to be nothing more than trivial puzzles. In order to provide the necessary background for this analysis, I shall begin by sketching a brief overview of Plato’s mathematical passages and discuss the criteria for aptly selecting them. Second, I shall explain what I mean by ‘mathematical examples,’ and reflect on their function in light of the discussion on παραδείγματα outlined (...) in theSophistand theStatesman. Against this framework, I shall move to a close examination of specific examples drawn from theTheaetetus(154c–55d), theRepublic(523c–24d), and thePhaedo(96d–97b, 100e–101d). By placing these examples in the broader context of pre-Euclidean mathematics, I shall show that their mathematical content is often less elementary than might appear at first sight. Moreover, by placing emphasis on the specific philosophical concerns that motivated their introduction, I shall argue that the examples are not merely nonsensical jokes. Even if their illustrative purpose is not always immediately clear, and even if they can sound playful and bizarre, they in fact fulfil an important function: by virtue of their power to generate wonder or confusion, they serve as exercises and act as a trigger with respect to the difficult philosophical issues they are intended to clarify.

There is more to be said about two of the topics Chris Peers addresses in his article Freud, Plato and Irigaray: A morpho-logic of teaching and learning (2012, Educational Philosophy and Theory, 44, 760–774), namely the Socratic method of teaching and Plato’s stance with regard to women and feminism. My purpose in this article is to continue Peers’s discussion of these two topics.

This paper examines the terms ‘elenchos’ and ‘elenchō’ as they occur in the Sophist in order to reveal a refined view of elenchos as a philosophical method. The explicit discussion of elenchos as a method in 226a6–231b8 must be read together with other passages described by these terms. Once this is done, it shall be seen that there are two types of elenchus employed in several ways. The first type, which I identify with the familiar Socratic elenchus, is used to (...) purge false opinions or to arrive at plausible answers to philosophical difficulties. The second type, which appears to be the Stranger’s own method, is used to positively disclose relations between Forms. On this reading, elenchos is not merely destructive or preparatory for dialectic; it also forms a part of it. (shrink)

In this paper, I provide an interpretation of the symploke ton eidon at Soph. 259e. My goal is to show that the specific metaphysical view expressed by the interweaving of forms best accounts for Plato’s explanation of truth and falsehood. In the first section, I introduce the fundamentals of the interpretation of the greatest kinds and their functions. After that, I propose an interpretation of the assertion at 259e, the upshot of which is that the interweaving of forms only deals (...) with extra-linguistic items, that it is related to both truth and meaning of linguistic items, in a very complex way which I aim to explain throughout the paper, and that it never involves sensible particulars. In the second section, I put forward my reading of the Stranger’s description of how logoi are structured and how they work. I pay particular attention to the view that words reveal being when they intertwine to form a statement. In the third section, I interpret the statements concerning Theaetetus. My goal is to advance a new reading of the specific role that kinds and their interweaving play with regard to the truth and falsehood of the statements concerning Theaetetus. The result is the very specific view that the kinds, which are the separated ontological cause of what happens in space and time, are the grounds of both the truth and the meaning of statements.

Truth of x (independently of any description of x) that it is f. A property f which holds of x but is not per se of x is said to hold per accidens of x. The essence of an individual is the sum of its per se properties. We can formulate the following: doctrine a: concrete individuals do not have essences though abstract entities do. Doctrine b: concrete individuals have essences but they do not individuate, whereas abstract entities have essences (...) which do individuate. Assumption i: we shall say that a thing exists insofar as it has an essence. Assumption ii: we shall say that we know a thing when we know what its per se properties are. We argue that plato held doctrine a and aristotle doctrine b (with assumptions i and ii). (edited). (shrink)

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)

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.

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.

In this paper I focus on the relationships between language, definition and being in Antisthenes. I start from Plato’s Sophist 251b–c, in which the reference to the ὀψιμαθεῖς stands out, and I conclude that it is not possible to identify these characters with Antisthenes. The conception of ὀψιμαθεῖς provides for the exclusive legitimacy of identical judgments, exploiting in an eristic sense an evident Eleatic legacy. But this position, rather than concordances, reveals serious opposition to what is surely known to us (...) of the logical and linguistic doctrines of Antisthenes. The most explicit testimony about the relationship between language and being in Antisthenes is handed down by Porphyry, who attributes to Antisthenes the equation λέγειν = λέγειν τι = λέγειν τὸ ὄν. My analysis intends to show that this equation is assumed by Antisthenes through a Socratic mediation and has a double objective: to ensure an objective reference of language, as opposed to Gorgias’ self-referential conception of language, and to nullify the antilogy, which is typical of sophistic argumentation. To it Antisthenes contrasts the ἐπίσκεψις τῶν ὀνομάτων, which is a development of Socratic ἐξετάζειν, and whose aim is to reach, at the end of the examination, no longer just a ὁμολογία, but a definition valid once and for all. Antisthenes is aware that there is a distinction between essence and quality, and with this, he moves a first important step beyond the univocal conception of being proper to Parmenides. The doxography will sum up Antisthenes’ position by describing him as the first philosopher to advance a definition of logos, i. e., definition. He bases his theory of definition on the identification of that attribute which is ἴδιον καὶ οἰκεῖον of the proposed object. Antisthenes coined the phrase τὸ τί ἦν to designate what the predicate is meant to say in a definition, i. e., the proper quality. This expression does not seem to identify the general notion of a predicate as such, but rather to indicate the determination or qualification necessary to actually define the object in question. In the final part of my article, I examine some testimonies that show how, with his theory of definition, Antisthenes is, and was considered already in antiquity, the precursor of the Stoic theory of definition, whose objective is, according to Chrysippus’ formula, to provide the explanation of what is proper (ἰδίου ἀπόδοσις).

With the use of a particular metaphor, which appears at the end of the Cratylus and is taken up with perfect symmetry at the beginning of the Theaetetus, Plato certainly wanted to indicate the succession of Cratylus–Theaetetus as an order for reading the two dialogues, which Trasillus faithfully reproduced in structuring the second tetralogy of Platonic dialogues. The claim of the theory of ideas, with which the Cratylus ends, must therefore be considered the background in which to place not only (...) the analysis of the name carried out in the Cratylus, but also the discussion and criticism of the epistemological theories examined and refuted in the Theaetetus. The transition from the discussion of the name to that of the logos is another important theoretical element that connects the two dialogues. Another one is the theory of knowledge, already precisely elaborated in the Cratylus, and taken up and deepened in the Theaetetus. Finally, the theme of false and error is a third theoretical element common to the two dialogues, which, starting from Euthydemus, finds its solution in the Sophist. (shrink)

This paper studies Sentence 16 of Porphyry's Pathways to the Intelligible. It is argued that it should be understood against the background of Plotinus' discussions of the similes of the waxen block and the aviary from Plato's Theaetetus. The first part of the paper concentrates on Plotinus' reception of these similes. In the second part of the paper Plotinus' discussions of the two similes are used to shed light on Sentence 16, in particular on the term προχείρισις. Furthermore it is (...) argued that Porphyry does not reject Plotinus' claim that, pace Aristotle, intellection does not require imaging. (shrink)

In Soph. 237b7–239a11 Plato lays out a sequence of arguments that are generally considered homogenous. An analysis of each argument can shed light on the need to differentiate their respective nature. Firstly, it will be shown that the arguments do not work only at the linguistic level, contrary to the way these passages are interpreted by most of commentators. The meta–linguistic nature of the third argument will be particularly emphasised. Secondly, it will be argued that the three arguments follow each (...) other according to a crescendo. The implications of this argumentative structure will be specifically appreciated. Both these results of the analysis induce to attribute a crucial importance to the notion of medamos on: the arguments do not aim to definitively exclude the possibility of a Parmenidean non–being; they play a positive role within the inquiry of the Stranger of Elea, inasmuch the thematisation of Parmenidean non–being is seriously taken into account and embraced at this stage of the dialogue. In fact it is only through this dialectical step that the Stranger gains the chance to proceed in the direction of a relational ontology and a new concept of non–being. The positive role played by the medamos on presupposes that this expression and the equivalent ones are not mere absurdities and can find place in the Platonic use of language; this implies that the notion of medamos on must have a justification in the framework of Platonic relational ontology and conception of language. The consideration of this aspect eventually gives the opportunity to return to the three arguments and present an explanation of their positioning in that stage of the dialogue. (shrink)

Any comprehensive interpretation of the "Theaetetus" has to provide answers to, among others, two very general questions concerning that dialogue: "What is Plato's relation to the problems faced in the "Theaetetus"?" and "What is the significance of the absence of the Forms from the discussion of the "Theaetetus", given their undoubted relevance to the topic of the dialogue, i.e. knowledge?" Predominantly, the answer given to the first question in the literature has been that the problems are those that Plato is (...) trying to tackle and the one to the second question, when it has been addressed at all, that the Forms are left out of the discussion because Plato no longer thought them relevant, either for having abandoned or seriously revised them, by the time of writing the "Theaetetus". In this study of the Wax Block and the Aviary models of judgment that occur in the second part of the "Theaetetus" as part of its discussion of the problem of false judgment, I argue that the problems faced there actually arise because of the neglect of Forms. The discussion of the second part is, I contend, carried out on a materialist ontology, an ontology assumed because it suits the definition of knowledge as true judgment which inaugurates that part of the dialogue, an ontology in no way subscribed to by Plato. The Wax Block is, I explain, a materialist model and fails in the case of judgments about numbers for treating them on a par with material subjects, ignoring their intelligible status. In particular, it fails to distinguish judging 5 and 7 to be 11 from judging 12 to be 11 because of its neglect of Forms; Plato would distinguish those judgments by distinguishing 5 and 7 from 12 with help from his part-whole analysis, to which the Forms are essential.

This article will contrast two portrayals of Protagoras: one in the "Theaetetus," where Socrates discusses Protagorean theory and even comes to his defense by imitating the deceased sophist; and another in the "Protagoras," where Socrates recounts his encounter with the sophist. I suggest that Plato wants listeners and readers of the dialogues to hear the dissonance between the two portraits and to wonder why Socrates so distorts Protagoras in the "Theaetetus." Protagoras in the "Protagoras" behaves and speaks in ways that (...) are incompatible with the Protagorean position presented in the "Theaetetus." . (shrink)

Selon Platon, la sensation n’est assurément pas en elle-même et par ellemême épistémique, car la science ne comporte rien de sensible, puisqu’elle advient sans l’intervention du corps, tandis que la sensation est précisément une affection qui unit âme et corps dans un même mouvementCe point fait l’objet d’un long passage du Théétète, au cours duquel la thèse de Protagoras selon laquelle science et sensation sont identiques est réfutée. Ceci est bien connu, mais il importe néanmoins de clarifier la raison pour (...) laquelle Platon invalide cette identité, ce qui rend impossible l’assimilation de la sensation à la science, que celle-ci soit, du reste, intuitive ou judicative.

Philosophy becomes speculative when it raises questions about the ultimate nature of being and thought. What does it mean to be? What does it mean to think? How are being and thought related? What does it mean to ask these questions? These questions have occupied a central place in philosophy throughout history, but have led a shadow existence in twentieth-century thought, which has cut the tie between reason and these fundamental questions, leaving the questions in the twilight, and reason instrumentalised. (...) A.N. Whitehead (1861-1947), one of the founders of analytic philosophy and co-author (with Bertrand Russell) of Principia Mathematica, is one of the few contemporary thinkers to have developed an explicit speculative philosophy. Unsurprisingly, his philosophy has played a marginal role in academic debates. In this study, the methodological foundation of Whitehead’s speculative thought is reconstructed. On the basis of a systematic and historical examination of the nature of the question of being, Whiteheads ontology of the event as the passage into novelty emerges in its full scope, allowing the reader to understand why and to what extent Whitehead has walked a different path than other contemporary thinkers. His philosophy contains a conception of reason that is not alien to newness and creativity while being more than procedural or pragmatic, and a mode of understanding existence that brings out the acuteness of freedom, value and legitimacy, as well as the unity of things, of thought and nature. In order to show what is really happening in this philosophy, the received interpretation of Whitehead’s ontology is radically dismantled. The central thought, that to be means to happen, is explained in a process of reiteration and gradual clarification, examining traditional philosophical problems in metaphysics and epistemology (on topics like: nature and matter, knowledge, categorical structure, freedom and necessity, truth and meaning, modality) from its perspective. What emerges is a philosophy in which the temporality of being, when taken seriously, changes the status of familiar problems and dualisms and offers possibilities for thought, which previously did not exist. Whitehead “hears” the classical questions of philosophy in a new way. Beyond the trenches of twentieth-century philosophy, Whitehead’s speculative thinking contains many elements that will be of value to those studying the foundations of thought today and looking for new directions. In a time when the dualism of nature and man is maintained cynically in our economies and dismantled, but only in a biologistic fashion and therefore only seemingly, as a cover-up, in science and philosophy, Whitehead’s new and creative way of hearing, and answering, old questions about ultimate concerns, when understood properly, is more up to date than ever before.

We show how an epistemology informed by cognitive science promises to shed light on an ancient problem in the philosophy of mathematics: the problem of exactness. The problem of exactness arises because geometrical knowledge is thought to concern perfect geometrical forms, whereas the embodiment of such forms in the natural world may be imperfect. There thus arises an apparent mismatch between mathematical concepts and physical reality. We propose that the problem can be solved by emphasizing the ways in which the (...) brain can transform and organize its perceptual intake. It is not necessary for a geometrical form to be perfectly instantiated in order for perception of such a form to be the basis of a geometrical concept. (shrink)

We examine the discussion about the definition of knowledge as true judgment accompanied by logos in Theaetetus 201c-210c, in order to ascertain which of the recent alternative interpretations is more consistent with the text. To accomplish this, we intend to analyze the text and explore in detail the secondary literature about it.

In this paper I use the traditional image of Plato as swan to suggest that interpreting Plato should not be a matter of getting to know what his doctrines are (a doctrinal approach), but rather a of getting to know Plato himself (a knowledge by acquaintance approach). I argue that the dialogues encourage the knowledge by acquaintance approach and discourage the doctrinal approach, through the use of Platonic anonymity, Platonic irony and Platonic self-effacement. I point out how the knowledge by (...) acquaintance approach values the rich diversity of historical opinions about Plato, whereas the doctrinal approach seeks to resolve such diversity once and for all. Even though the doctrinal approach has powerful tools at its disposal—such as the testimony of Aristotle, the principle that the main speaker in a dialogue is Plato’s mouthpiece, and stylometric analysis—the product of a doctrinal approach is a brand of Platonism that is weak, rigid, and ultimately dispensable. The philosophy of Plato is worthy of more respect than that, and it repays such respect with wider understanding. (shrink)

My dissertation is devoted to an examination of the resolution of fallacy in Plato's Euthydemus. It is a familiar claim that the Euthydemus champions Socratic argumentation over sophistical or eristic reasoning. No consensus however exists regarding either the nature or philosophical significance of Socrates’ treatment of the fallacies he confronts. I argue that a careful reading of the dialogue reveals that the Socratic response to fallacious reasoning is conducted at two different levels of philosophical sophistication. Socrates relies upon the resources (...) of Socratic dialectic in responding to sophisms due to ignorance of refutation. Insofar as Socratic dialectic is grounded in a grasp of the nature of genuine refutation, the objections it raises to false refutation are fully explanatory. On the other hand, Socrates employs various self-refutation arguments against theses which depend on false assumptions regarding the nature of predication---for example, the thesis that false speaking is impossible. It is however characteristic of Socratic dialectic that this method of examination cannot explain why the sophists’ theses are false. The Socratic response to fallacy in these cases is non-explanatory in this sense. On the other hand, these limitations on Socratic expertise are overcome in other passages in the dialogue which are replete with clues to the reader that point to a genuine explanation and resolution of the sophists’ arguments for their various theses. In particular, the reader is invited at every turn to modify, clarify, or reject various assumptions made by the brothers regarding the nature of predication. Here Plato implicitly relies on the results of what I call higher dialectic. This theory, which receives explicit formulation in the Sophist, is conceptually rich enough to expose and dispose of the various false assumptions upon which the sophists’ theses rest. I conclude that the Euthydemus is concerned to identify Socratic dialectic as only a part of philosophy, and to locate and strictly delimit its epistemological status as lying above eristic and the rhetorical arts, but below that of dialectic as that is conceived in the Republic and even later dialogues---thus anticipating the Sophist’s conception of Socrates as the practitioner of a ‘noble sophistry’, and the elenchus as a propaedeutic to philosophy, which purges the soul of false beliefs.

Although most scholars trace the Liar Paradox to Plato’s contemporary, Eubulides, the paper argues that Plato builds something very like the Liar Paradox into the very structure of his dialogues with significant consequences for understanding his views. After a preliminary exposition of the liar paradox it is argued that Plato builds this paradox into the formulation of many of his central doctrines, including the “Divided Line” and the “Allegory of the Cave” and the “Ladder of Love”. Thus, Plato may have (...) been the first to formulate the view that Graham Priest calls dialetheism, roughly, the view that some contradictions are, in an illuminating way, inescapable and true. The paper argues that Plato builds this Liar paradox into the formulation of his signature views because he holds that the attempt by finite human beings to theorize about transcendent realities results in the simultaneous necessity, and impossibility, of transgressing the limits of language—leading to the paradoxes. Finally, it is argued that the existence of these paradoxes in these Platonic doctrines is the direct result of an intrinsic hermeneutical circle in Plato’s aforementioned signature views. (shrink)
