Plato: Epistemology

La presente tesis doctoral se suma al proyecto general del grupo de investigación “Eidos: Hermenèutica, Platonisme i Modernitat”, ofreciendo una nueva lectura e interpretación del diálogo platónico Fedro. La tesis se divide en tres apartados. El primero, que sirve de introducción, establece los objetivos principales de la tesis y el método de trabajo que hemos seguido; además, ofrece toda una serie de consideraciones generales sobre el texto, como su autenticidad, su fecha de composición, una caracterización general de sus personajes y (...) su fecha de acción dramática. El segundo es con diferencia el más extenso de todos y constituye propiamente el núcleo de la tesis. A lo largo de sus once sub-apartados se ofrece una lectura pormenorizada del diálogo, en la que discutimos con algunas de las interpretaciones más relevantes y ofrecemos luz sobre los problemas más sustantivos del diálogo. Por una parte, se analizan las diferentes partes del diálogo, como la escena inicial, cada uno de los tres discursos eróticos, y la discusión posterior sobre la retórica tradicional, la dialéctica y la escritura; por otra, se trata de ofrecer una visión general de cómo se unen entre sí las distintas partes del diálogo y en qué sentido unas derivan de las otras. Esta manera de proceder nos ha permitido encontrar la controvertida unidad dramática y temática del diálogo: de un lado, la segunda parte del diálogo se muestra como una continuación necesaria de la primera; de otro, los temas del amor, el alma, la retórica tradicional y la dialéctica aparecen como diferentes aspectos a tratar para resolver el problema que Platón presenta en la escena inicial del diálogo a través de la figura de Fedro. Por último, el tercer apartado recoge de manera sintética las principales conclusiones del análisis llevado a cabo en desarrollo de la tesis. En él subrayamos el carácter unitario del diálogo y la relevancia capital que tiene la correcta comprensión de esta obra para la consideración de la naturaleza de las obras de Platón en general.

El presente artículo defiende que Platón bromea cuando su Sócrates afirma estar inspirado o bajo posesión divina en Fedro 238d y Crátilo 396d. Para ello, primero se sitúan en contexto ambos pasajes; a continuación, se muestra que a lo largo de todo el corpus Platón contrapone el conocimiento y el arte (τέχνη) al falso saber y a la inspiración (ἐνθουσιασμός); en tercer y cuarto lugar respectivamente, leemos los pasajes en cuestión en función de esta contraposición, para mostrar que hay que (...) desconfiar de cuanto dice Sócrates cuando burlonamente afirma estar inspirado.

The critique of the poetry in Plato’s Ion unfolds in a clearly political context in which, in contrast to the old model of knowledge represented by poetry, Plato presents a new model, identified with philosophy, which questions the legitimacy of poets and rhapsodists as competent guides of the polis and citizens. In this critique, the characters and dramatic elements of dialogue are fundamental. Thus in Ion and Socrates the Athenian philosopher brings together all the characteristics that describe a real rhapsodist (...) of that time as well as the philosophical activity of the historical Socrates.

Plato’s Phaedrus is a dialogue in which rhetoric is not only discussed, but also displayed. The first half of the plot depicts a rhetorical contest in which Socrates himself offers two opposite speeches on love, a kind of dissoi logoi. The current paper tries to explain that the second half of the dialogue offers the necessary keys to understand that for Plato true rhetoric is nothing but dialectic and that beyond the apparent antilogic exercise carried out by Socrates there can (...) be found philosopher’s dialectical practice itself. Last but not least, the article defends that dialectic does not necessarily deal with Forms. (shrink)

The current article offers a new reading of Socrates’ prayer to Pan in Plato’s Phaedrus. By means of a comprehensive approach, the paper shows that the prayer not only gathers together the most relevant topics dealt with during the conversation but it also exhorts us to engage in the way of life depicted by Socrates’ character, namely that of philosophy, which can be clearly distinguished from that of traditional rhetoric. To this extent, eros and logos, two elements closely related to (...) Pan, show themselves to be of primary relevance. Besides these issues, we discuss the puzzling nature of the prayer, defending the idea that it was authored with the same writing method as the full dialogue. Socrates’ psychagogic attempt with Phaedrus is analogous to Plato’s didactic effort to engage the reader in philosophy: instead of supplying a straight message which must be learnt by heart by Phaedrus or the reader, both Socrates and Plato offer friendly logoi intended to promote active research in the receivers.

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)

Due to its discussion of the question of non-being and its intention of grounding the philosophical discourse, Plato ́s dialogue The Sophist occupies a central position in the history of philosophy. The purpose of this article is to relate the definition method used by Plato in the dialogue (the diaeresis) with his conception of philosophical discourse. The different definitions for the sophist proposed in the dialogue are not only part of Plato's polemic against sophistry, but underpin the very Platonic conception (...) of the philosopher and philosophical discourse. While dialectics would be the method employed by the philosopher to arrive at knowledge and wisdom, sophistry would be only an imitation of true knowledge and true wisdom. (shrink)

Education is crucial to the overall development of all communities. Since the early days of Greek philosophy, philosophers have made significant contributions to the advancement of education for both individuals and the states. Greek philosophers, notably Plato, emphasized the importance and relevance of education for his conceptual ideal state. His educational ideas were rooted in his philosophy, notably idealism, and it continues to have a great effect, particularly on education. Idealism focuses on ideas and believes that genuine knowledge can be (...) found in the ideas' world. His age-based educational system advocates both public education and equal access. The purpose of this paper is to revisit his educational ideas in depth and have a better understanding of them in terms of contemporary education. This paper adopts an analytical strategy to achieve its purposes, and it maintains, based on secondary evidence, that the features of the educational ideas of Plato are truly pertinent and might be applied to contemporary education after appropriate integration.

El presente artículo contiene una lectura cruzada del Fedro y el Crátilo en la que se aclaran algunos de sus ejes temáticos centrales con el fin de sacar a relucir las constantes del pensamiento platónico que ambos diálogos comparten. La descripción de la dialéctica presente en el Fedro encaja con una definición socrática del Crátilo que explicita que el nombre es un instrumento al servicio del dialéctico. Todo ello nos lleva a concluir que la técnica dialéctica, además de constituir el (...) principal mecanismo regulador de la oratoria, se postula en los diálogos platónicos como un procedimiento de corrección que permite validar cualquier tipo de proposición y aproximar a la verdad los más variados discursos y representaciones de la realidad. Abstract: The current paper contains a comparative reading of the Phaedrus and the Cratylus. Some of their central topics are here contrasted in order to highlight the characteristic traits of Platonic thought present in both dialogues. The description of dialectic in the Phaedrus fits well with a Socratic definition in the Cratylus which clearly specifies that names are tools at the service of the dialectician. This evidence leads us to the conclusion that -besides being the main mechanism to control and judge rhetoric- dialectical technic appears in the dialogues as the only correcting procedure that makes it possible to verify any sort of proposition and bring speeches and depictions of reality closer to the truth.

At key moments in the Phaedrus and the Republic, Socrates qualifies our capacity to “see” the highest realities (the “place of being,” the “Good beyond being”) with the adverb “mogis” (mogis kathorosa, Phdr. 248a; mogis horisthai, Rep. 517b). Mogis can be used to indicate either the toilsome difficulty of some undertaking or the subject’s proximity to failing to accomplish the undertaking. Socrates uses mogis to qualify the nature of the human soul’s capacity to make the intellectual ascent and see the (...) divine, but it is not prima facie clear whether the qualification is meant to express (1) the difficulty we have in undertaking the intellectual ascent (a comment on the effort required) or (2) the fact that the human soul’s capacity to make the intellectual ascent will, on account of its limitations, only “just barely” be achieved, if at all. After discussing the uses of mogis in classical literature and surveying Plato’s uses of mogis across the corpus, I interpret Plato’s use of mogis at Phaedrus 248a, arguing that mogis kathorosa should be translated as “only gets a good look at the things that are with much toil” rather than the more common “scarcely able to gaze upon the things that are.” I then turn to the parallel passage at Republic 517b and argue against a prominent account, put forward by John Sallis, among others, of Plato’s understanding of divine inaccessibility. Whereas Sallis et al. argue that Plato’s use of mogis indicates that which is to be seen at the acme of the ascent is only “barely glimpsed” on account of the fact that it “withdraws” from our view, I argue instead that Plato’s use of mogis indicates that though we can “get a good look” at the highest realities, that good look is qualified by their inexhaustible excess. The human capacity to see the highest realities is qualified because there is “always more to see,” not because that which is there to be seen “withdraws” from view, and still less because there is some intrinsic limitation to human intellectual vision that prevents us from apprehending the highest realities. Accordingly, the divine is accessible but never exhaustible. (shrink)

This chapter examines Plato’s account of the method of learning by paradeigma (‘model’) in the Statesman. I first explain what the method is. I then consider the two parties who are described as using it: children who are learning to read and write and the dialogue’s two interlocutors. I highlight some parallels between each party’s use of the method. These parallels illuminate important features of dialectical inquiry in general and the Visitor and Young Socrates’ inquiry in particular, including the nature (...) of the knowledge they ultimately hope to achieve and one stage in the complex process by which they aim achieve it.

Plato’s Philebus has often been said to lack unity as a dialogue. In particular, what is the relation between the methodological and metaphysical reflections early in the dialogue and the investigations of pleasure and knowledge that constitutes its main subject matter? This chapter argues that Plato’s Philebus provides a division of knowledge (epistēmē), which satisfies the methodological norms explained earlier in the dialogue. In order to make this claim, Socrates is shown to provide an example of a cross-cutting division not (...) unlike those found in the Gorgias and Sophist. With this account of the division in place, we are able to better appreciate how the divine method of inquiry ensures the unity of all forms of knowledge. (shrink)

Ignorance is commonly assumed to be a lack of knowledge in Plato’s Socratic dialogues. I challenge that assumption. In the Protagoras, ignorance is conceived to be a substantive, structural psychic flaw—the soul’s domination by inferior elements that are by nature fit to be ruled. Ignorant people are characterized by both false beliefs about evaluative matters in specific situations and an enduring deception about their own psychic conditions. On my interpretation, akrasia, moral vices, and epistemic vices are products or forms of (...) ignorance, and a person who lacks knowledge is not necessarily ignorant. (shrink)

Plato’s Timaeus reveals a cosmos governed by Necessity and Intellect; commentators have debated the relationship between them. Non-literalists hold that the demiurge, having carte blanche in taming Necessity, is omnipotent. But this omnipotence, alongside the attributes of benevolence and omniscience, creates problems when non-literalists address the problem of evil. We take the demiurge rather as limited by Necessity. This position is supported by episodes within the text, and by its larger consonance with Plato’s philosophy of evil and responsibility. By recognizing (...) the analogy between man and demiurge, the literal reading provides a moral component that its non-literal counterpart lacks. (shrink)

The main idea of this allegory is the difference between people who simply experience their sensory experiences, and call that knowledge, and those who understand real knowledge by seeing the truth. The allegory actually digs into some deep philosophy, which is not surprising since it comes from Plato. Its main idea is the discussion of how humans perceive reality and if human existence has a higher truth. It explores the theme of belief versus knowledge. The Perception Plato theorizes that the (...) group of people tied up in the cave would assume that the shadows they see on the wall are reality. Plato's theory further states that the echoing sounds the prisoners hear are perceived as reality. This false reality is all that the people in the cave know. They have no true knowledge of the real world. However, they fully believe that what they see on the cave wall is reality, and even try to name the shadows they see passing by. Plato's cave allegory further proposes that one of the prisoners escapes or gains freedom from the cave. The freed prisoner moves toward the fire, which temporarily blinds him. As he gains his eyesight and moves into the real world, he gains a greater sense of reality. (shrink)

It is widely accepted that ruling is the sole prerogative of Plato’s philosopher-rulers because they alone possess knowledge (ἐπιστήμη). This knowledge is knowledge of the Good, taken to be the only knowledge there is in Kallipolis. Let us call this the sufficiency condition thesis (the SCT). In this paper, I challenge this consensus. I cast doubt on the adequacy of the SCT, arguing that part of the training and education of the philosopher-rulers involves their gaining practical wisdom (φρόνησις) and experience (...) (ἐμπειρία). To succeed in this, I have two main aims. First, I argue that the philosopher-rulers must attain optimum cognitive success in these three modes of cognition to function efficiently in ruling. This involves showing that Plato, for his political project, appeals to other senses of cognitive successes besides his strictly metaphysical epistemology. Second, I attempt to demonstrate how these three modes of cognition coalesce or coincide in ruling the perceptible world, especially in the judgement and determination of concrete perceptible matters.

Main purpose of this work is to state the ideas of Plato about God, the universe, and the creation of universe. While explaining about his ideas on this subject, not only his time, but also ideas of the philosophers preceding him are taken into consideration. It also includes usual views and belief systems about the God, the universe and the creation of universe during his time. Thus, we had a chance to examine Plato’s ideas about our subject in detail. Our (...) work, which is formed by Literature Reading method, has approached Plato’s ideas and the preceding ideas as different categories, classified each section as the God, the universe, and the creation of universe to examine.

The Parmenides has been unduly overlooked in discussions of hypothesis in Plato. It contains a unique method for testing first principles, a method I call ‘exploring both sides’. The dialogue recommends exploring the consequences of both a hypothesis and its contradictory and thematizes this structure throughout. I challenge the view of Plato’s so-called ‘method of hypothesis’ as an isolated stage in Plato’s development; instead, the evidence of the Parmenides suggests a family of distinct hypothetical methods, each with its own peculiar (...) aim. Exploring both sides is unique both in its structure and in its aim of testing candidate principles. (shrink)

In the Republic Plato contrasts dialectic with mathematics on the grounds that the former but not the latter gives justifications of some kind for its hypotheses, pursuing this process until it reaches ‘an unhypothetical principle’. But which principles are unhypothetical, and why, is rather dark. One reason for this is the scarcity of forms of that precious word, ‘unhypothetical’ (aνυπoθετος), used only twice by Plato (Rep. 510 b 7, 511 b 6) and just once by Aristotle (Metaph. 1005B14). But that (...) very scarcity also suggests the intriguing possibility that Aristotle has Plato’s text in mind when he uses the word, so we might expect to understand Plato better by grasping how Aristotle took him. That is a notoriously defeasible assumption since plenty of modern accounts of Plato want to save him from Aristotle’s numerous critiques, and hence imply that the master of them that know frequently missed the point when it came to his own master. But surely we can be more confident that Aristotle will give us access to Plato when it appears not merely that he is dealing with the same topic, but using the same rare vocabulary to boot. Hence the understandable temptation to turn to Metaphysics Γ for help in identifying Platonic unhypothetical principles. I shall argue that Aristotle is indeed thinking of Plato’s text when he uses the word for ‘unhypothetical’, and further that what is explicitly an unhypothetical principle for Aristotle might well have been one for Plato too. But later I shall claim that their joint use of a much more common word in the same philosophical context is either coincidence or misunderstanding on Aristotle’s part, for he must mean something different by it from what Plato means.

Plato’s Theory of Perception This research deals with Plato's perceptual theory, as the perceptual theory in Plato's philosophy represents one of the steps of the Plato’s epistemology. Plato divided knowledge into four categories: Sensory knowledge, presumptive knowledge, mathematical knowledge, and rational knowledge. The theory of sensory perception is in the first place, so this research focuses on the statements, the meaning of perception, the senses, the difference between sensation and mind, the topics of sensory perception, and the nature of the (...) work of sensory perception.

At the end of the Meno, Socrates suggests that genuine virtue is knowledge. This is surprising because he has recently concluded that virtue is true opinion. I show that Socrates’ new position is motivated by two commitments. First, that being virtuous requires being responsible for the correctness of one’s actions. Second, that only a knower has this kind of ownership of action. An implication of my argument is that, despite his emphasis on virtuous action in the Meno, Socrates endorses an (...) agent-centred ethics. He thinks the epistemic status of the agent is essential to the assessment of her goodness. (shrink)

The book "Theory of Forms: The Construction of Plato and Aristotle’s Criticism" focuses on two main aspects, construction and criticism. The constriction of Forms theory is the basis on which Plato built all of his philosophy and which influenced all forms of ideas philosophy that emerged after Plato. The research topic was completed by adding Aristotle's critique of the theory of Forms in order to put a clear picture in front of the reader, which was presented by Plato himself and (...) Aristotle's criticism of this theory. -/- Therefore, the book consists four chapters, the first chapter covers the following topics; The philosophical roots of Plato's theory of Forms, The numbers in the Pythagorean school, The Heraclitus' idea of change, Anaxagoras’ idea of Mind, Sophists. Chapter two, Plato's theory of Forms. Definitions of the Forms. The importance of the Forms, The existential and logical significance, Evidence of Forms, Evidence that knowledge is remembering. Chapter Three, Forms and Levels of Knowledge, Dialectic ,Inferential knowledge, Mental knowledge The fourth chapter, The nature of the Forms existence and its being Causes. Forms as numbers and their relationship to movement. The problem of Participation. The final Evaluation of Forms. (shrink)

The Five Greatest Kinds discussed in Plato‘s Sophist are taken to be just one instance of a fivefold structure found in various related texts. Contemporary linguistic theories are a source for ideas about its functioning.

In book X, Plato's rejection of mimetic poetry can be read as a parallel to rejecting the conventions of the poetic style contemporary to his time. This rejection can, owing to the premises derived and the analyses made in this paper, further be read as to suggest that Plato presses for a reformation of the poetic vocabulary. That is, as to suggest that Plato proposes that the non-rational imagistic tradition, embodied in mimetic poetry, get replaced by a rational and noetic-aspiring (...) rhetoric that opts for knowledge and truth.

This paper provides an original approach to research on the logical processes that determine how certain forms participate in others. By introducing the concept of relational participation, the problems of self-referentiality of the Platonic forms can be dealt with more effectively. Applying this to the forms of likeness and unlikeness in Parmenides 132d-133a reveals a possible way to resolve different versions of the Third Man Argument. The method of generating numbers from oddness and evenness may also be of interest; relational (...) participation in these forms clarifies the interpretation of Parmenides 143e-144a. (shrink)

En la primera parte del Teeteto Sócrates refuta tres tesis que considera estrechamente vinculadas entre sí: la tesis de Teeteto que identifica conocimientoy percepción, la tesis relativista y la tesis movilista. El propósito de este trabajo es mostrar que en tres de las refutaciones ofrecidas contra estas posiciones se exhibe una misma estrategia tendiente a remitis a un prerrequisito dialéctico vinculado a la pretensión de verdad. ESta constituiría una estrategia radical, en el sentido de que pone en cuestión la misma (...) posibilidad de enmitir la propia tesis por parte del adversario. (shrink)

Emotions ( pathè) such as anger, fear, shame, and envy, but also pity, wonder, love and friendship have long been underestimated in Plato’s philosophy. The aim of Emotions in Plato is to provide a consistent account of the role of emotions in Plato’s psychology, epistemology, ethics and political theory. The volume focuses on three main issues: taxonomy of emotions, their epistemic status, and their relevance for the ethical and political theory and practice. This volume, which is the first edited volume (...) entirely dedicated to emotions in Plato’s philosophy, shows how Plato, in many aspects, was positively interested in these affective states in order to support the rule of reason.

In consoling the lover of sights and sounds at Republic 475e4-479d5, Socrates describes a tripartite distinction among knowledge, doxa, and ignorance. Socrates claims that knowledge is ‘over’ what-is, doxa is over what is and is-not, and ignorance is over nothing at all. I argue that Plato shows that doxa and ignorance are also related to what-is. While knowledge, doxa, and ignorance interact with different first-degree objects, these three capacities have a common second-degree object: what-is. The fact that Socrates claims that (...) doxa is inferior to knowledge, and ignorance is inferior to doxa, shows that these three capacities have a shared aspiration that doxa and ignorance each fail to fulfill in their own way. Following Plato’s analogy to the senses at 477c1-d1, I use an analogy to the senses to demonstrate Plato’s understanding of the relationship between doxa and what is. (shrink)

Irwin, Leonard Brandwood, Eric Brown, Agnes Callard, Gail Fine, Suzanne Obdrzalek, Gábor Betegh, Elizabeth Asmis, Henry Mendell, Constance C. Meinwald, Michael Frede, Emily Fletcher, Verity Harte, Rachana Kamtekar, and Rachel Singpurwalla. -/- The first edition of the Cambridge Companion to Plato (1992), edited by Richard Kraut, shaped scholarly research and guided new students for thirty years. This new edition introduces students to fresh approaches to Platonic dialogues while advancing (...) the next generation of research. Of its seventeen chapters, nine are entirely new, written by a new generation of scholars. Six others have been thoroughly revised and updated by their original authors. The volume covers the full range of Plato's interests, including ethics, political philosophy, epistemology, metaphysics, aesthetics, religion, mathematics, and psychology. Plato's dialogues are approached as unified works and considered within their intellectual context, and the revised introduction suggests a way of reading the dialogues that attends to the differences between them while also tracing their interrelations. The result is a rich and wide-ranging volume which will be valuable for all students and scholars of Plato. (shrink)

O presente artigo aduz a interpretação de Martin Heidegger do conceito de ἀλήθεια – tradicionalmente traduzido por verdade – na filosofia de Platão, a partir da célebre alegoria da caverna presente na República. Segundo o posicionamento inicial de Heidegger, ἀλήθεια era originalmente pensada pelos gregos como desvelamento até Platão, com quem o sentido do termo se transforma e passa a expressar a retitude da percepção. Contudo, as críticas filológicas proferidas contra Heidegger por Paul Friedländer fizeram com que seu posicionamento histórico-filológico (...) inicial fosse em certa medida alterado, passando a sustentar que os gregos antigos, embora tivessem experimentado o acontecimento original de ἀλήθεια, não foram capazes de expressá-lo como tal. Por conseguinte, Heidegger também abandonou a tese de que houve em Platão uma mudança essencial no sentido de ἀλήθεια. (shrink)

The kind of self-knowledge at issue in the eye-soul analogy of the Alcibiades is knowledge of one’s epistemic state, i.e. what one knows and does not know, rather than knowledge of what one is. My evidence for this is the connection between knowledge of one’s epistemic state and self-improvement, the equivalence of self-knowledge to moderation, and the fact that ‘looking’ into the soul of another is a metaphor for elenctic discussion. The final lines of the analogy clarify that the part (...) of the soul one ‘looks’ into and the part one learns about when learning about one’s epistemic state is divine. (shrink)

This article defends three claims. First, that collection and division in the Phaedrus are described as procedures that underlie human speaking and thinking in general, as well as philosophical inquiry, and are not identified with either. Second, that what sets the dialectical use of these procedures apart from their ordinary use are philosophical suppositions independent of the procedures of collection and division themselves; for that reason, collection and division cannot be identified with dialectic as such. Third, that the second part (...) of the Phaedrus is concerned with the broader question how noble or beautiful speaking, in general, may be said to depend on dialectic as much as it is concerned with the question how rhetoric, as a kind of expertise, is related to dialectic.

From my ongoing "Metalogical Plato" project. The aim of the diagram is to make reasonably intuitive how the Socratic elenchos (the logic of refutation applied to candidate formulations of virtues or ruling knowledges) looks and works as a whole structure. This is my starting point in the project, in part because of its great familiarity and arguable claim to being the inauguration of western philosophy; getting this point less wrong would have broad and deep consequences, including for philosophy’s self-understanding. -/- (...) (i.) is the first pass at elenchos in which the Socratic interlocutor does not reflect on knowledge being the crux of the problem. (ii.) is the second, rarer, reflective pass in which they are, making the investigation explicitly about knowledge. Its centrality in the Charmides makes that neglected dialogue of superlative importance. This structure is also the gateway through which the discussion/dialectic crosses into the Agathology (discussion of the form of the good) at Republic 505. -/- The problem of elenchos, then, grasped as a whole structure, is that it seems that knowledge can neither satisfactorily be included in nor excluded from its own scope. The development of the ti esti (“what is ---?”) question leads to the introduction of knowledge into its own scope (i. implicitly, as goodness contrasted with blind rule-following ii. explicitly qua knowledge) while the development of the dual peri tinos (“----about what?) question leads to K’s elimination from its own scope. The introductions are motivated to avoid contradiction, but produce regress; the eliminations are motivated to avoid regress, but produce contradiction. In scholarship, and in the history of philosophy, the ti esti question is universally recognized, to the point of being identified with philosophy’s origin and essence; the peri tinos question is neglected textually and never recognized as the equal dual to the ti esti. This, I claim, has blocked the development of a nontrivial logical appreciation of what Plato's Socrates is up to. (One rather disastrous effect of this neglect is taking Aristotle as the beginning of the development of logic, rather than, correctly, for the beginning of logic’s fatal separation from mathematics and dialectic.) -/- Further, because of this monopticism of the ti esti, the function of consistency in the elenchos has not been understood, even with respect to the ti esti. The ti esti is actually in search of completeness, given a norm of consistency; the peri tinos is in search of consistency, given a norm of completeness. Only appreciating the two questions as dual allows space in the structure to clarify these different orientations relative to consistency. (And, dually, to completeness, whose function in the elenchos is generally entirely missed by scholars and relegated to discussions of eros; it's not out of place there, of course, but its significance is secured here.) Recognizing the duality of the ti esti and peri tinos questions is thus the royal road, in the Socratic-Platonic context, to catching sight of what we post-Cantorians can recognize as the metalogical duality of consistency and completeness. (The salutary disruptive effects of this Plato-Cantor proximity have, of course, been traced in complementary ways by Badiou.) -/- Note that the diagram is supposed to provide a relatively accessible orientation, not to stand on its own, and certainly not to be the last word on any subject. An important qualification (telegraphed in the previous paragraph) is that what elenchos shows is not finally circular or paradoxical, though the problem first presents as such (stubbornly, obdurately, as "difficult" Plato's Socrates always says with characteristic understatement). What is depicted here is meant, at a first pass, to be the shape of that first presentation, the form of the problem of elenchos, rather than of its solution. It's not an accident that this problem strongly resembles "Russell's paradox" (not Russell's not a paradox.) Problem is to solution as RP is to the diagonal theorems. (shrink)
