Plato: Epistemology

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.

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.

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)

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)

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)

The present chapter investigates Heidegger's early understanding of Platonic dialectic in its contrast to sophistry as this comes to expression in his lectures on Plato's Sophist.

In this paper, I question a widespread reading of a passage in the last part of the Phaedrus dealing with the science of dialectic. According to this reading, the passage announces a new method peculiar to the later Plato aiming at defining natural kinds. I show that the Phaedrus itself does not support such a reading. As an alternative reading, I suggest that the science of dialectic, as discussed in the passage, must be seen as dealing primarily with philosophical rhetoric (...) and knowledge of human souls.

The “battle” between corporealists and idealists described in Plato’s Sophist 245e6–249d5 is of significance for understanding the philosophical function of the dramatic exchange between the Eleatic guest and Theaetetus, the dialogue's main interlocutors. Various features of this exchange indicate that the Eleatic guest introduces and discusses the dispute between corporealists and idealists in order to educate Theaetetus in ontological matters. By reading the discussion between Theaetetus and the Eleatic guest in the light of these features, one comes to see that (...) the primary audience for the proposal advanced by the Eleatic guest in this passage, namely that being is power, is not any of the participants in the “battle,” as has been commonly assumed, but Theaetetus himself—a fact to bear in mind in any viable interpretation of the passage.

This article explores the motif of psychic nourishment in Plato’s Protagoras. It does so by analyzing what consequences Socrates’ claim that only a physician of souls will be able adequately to assess the quality of such nourishment has for the argument of the dialogue. To this purpose, the first section of the article offers a detailed analysis of Socrates’ initial conversation with Hippocrates, highlighting and interpreting the various uses of medical metaphors. Building on this, this section argues that the warning (...) Socrates utters against sophistry is much more complex than commonly assumed, and further that Socrates demonstrates his own skill as a physician of souls during this conversation. The second part analyzes the first half of Socrates’ discussion with Protagoras, arguing that Socrates here demonstrates another aspect of his expertise as a physician of souls by making Protagoras participate, although against his will, in bringing the unhealthy character of his teachings to light.

According to many interpreters, Socrates in the Euthyphro thinks that an answer to ‘what is the holy?’ should pick out some feature that is prior to being holy. While this is a powerful way to think of answers to the ‘what is it?’ question, one that Aristotle develops, I argue that the Euthyphro provides an important alternative to this Aristotelian account. Instead, an answer to ‘what is the holy?’ should pick out precisely being holy, not some feature prior to it. (...) I begin by showing how this interpretation allows for a straightforward reading of a key argument: Socrates’ refutation of Euthyphro’s proposal that the holy is the god-loved. Then I address considerations that seem to favor the Aristotelian account. I end by explaining how answers to ‘what is f-ness?’ questions are informative on this account, even though they do not identify anything other than f-ness. (shrink)

Sut Jhally begins his essay “Advertising at the Edge of the Apocalypse” with the following provocative claim: “Advertising is the most powerful and sustained system of propaganda in human history and its cumulative effects, unless quickly checked, will be responsible for destroying the world as we know it.” Jhally argues that the advertising industry, in fostering an association between human aspiration and desire for consumable goods, creates an artificial demand for such goods that is, at once, far in excess of (...) what is needed for human flourishing and catastrophic to the global environment. Jhally sees capitalism as the ultimate culprit. In a system in which wealth is defined as a “vast collection of commodities” (Marx, Capital), those who produce such commodities have no other choice but to promote excess consumption. Hence the advertising industry emerges as the propaganda arm of capitalism. My paper argues that, though Jhally’s analysis of the problem is both compelling and alarming, his diagnosis fails to reach its heart. Indeed, it is not Marx but Plato who provides us with the terms needed both to understand and respond to the problem Jhally cites. My paper provides a Platonic analysis of these issues and concludes with some suggestions as to how to address them. (shrink)

A close reading of Socrates' refutation of the final proposed definition of knowledge, "true opinion with an account." I examine the provocations to further thinking Socrates poses with his dilemma of simplicity and complexity and then by his rejections of the three senses of "account," and I argue that these provocations guide the responsive reader to that rich and determinate understanding of the sort of 'object' which knowledge requires that the Parmenides and the Eleatic dialogues will go on to explicate.

Book review of Tom Rockmore's "Kant & Phenomenology," which appeared in "Review of Metaphysics" in 2011.

Philosophers of education often view the role of religion in education with suspicion, claiming it to be impossible, indoctrinatory or controversial unless reduced to secular premises and aims. The ‘post-secular’ and ‘decolonial’ turns of the new millennium have, however, afforded opportunities to revaluate this predilection. In a social and intellectual context where the arguments of previous generations of philosophers may be challenged on account of positivist assumptions, there may be an opening for the reconsideration of alternative but traditional religious epistemologies. (...) In this article, we pursue one such line of thought by revisiting a classic question in the philosophy of education, Meno’s Paradox of inquiry. We do this to revitalise understanding and justification for religious education. Our argument is not altogether new, but in our view, is in need of restatement: liturgy is at the heart of education and it is so because it is a locus of knowledge. We make this argument by exploring St Augustine’s response to Meno’s Paradox, and his radical claim that only Christ can be called ‘teacher’. Though ancient, this view of the relationship of the teacher and student to knowledge may seem surprisingly contemporary because of its emphasis on the independence of the learner. Although our argument is grounded in classic texts of the Western tradition, we suggest that arguments could be made by drawing on similar resources in other religious traditions, such as Islam, that also draw upon the Platonic tradition and similarly emphasise the importance of communal and personal acts of worship.

Through detailed analysis of Plato’s Meno, I identify and set general argumentative rules (useful both to scientists and philosophers) concerning how to use definitions. I show how the character Socrates establishes strong requirements for knowledge in general, i.e., that the knowledge of the definition of a thing must be prior to the knowledge of properties or instances of that thing. Socrate’s requirements and the way he characterizes a definition (as coextensive to the definiendum, not circular, true and explanatorily relevant) lead (...) Meno to aporia and to enunciate the famous Meno’s Paradox concerning the impossibility of inquiry for knowledge. That only occurs because Meno is unable to identify Socrate’s dialectical move: strong requirements for knowing a definition, the priority of the knowledge of the definition and the taking of all knowledge to be like the knowledge by acquaintance. After the paradox, Socrate’s proceeds the discussion using hypotheses to map the truth conditions of some theses Meno is inquiring about. I explain what are Meno’s paradox, the socratic definition and the Method of Hypotheses, in a way só as to find in this classical text in the history of philosophy general principles of argumentation that are still usefull today.

The primary aim of this paper is to argue that the value of understanding derives in part from a kind of subjective stability of belief that we call epistemic resilience. We think that this feature of understanding has been overlooked by recent work, and we think it’s especially important to the value of understanding for social cognitive agents such as us. We approach the concept of epistemic resilience via the idea of the experience of epistemic ownership and argue that the (...) former concept has Platonic pedigree. Contrary to longstanding exegetical tradition, we think that Plato solves the “Meno problem” with an appeal to the epistemic resilience characteristic of understanding, not the well-groundedness characteristic of canonical cases of propositional knowledge. Finally, we apply our discussion to the case of science outreach and the challenge of global warming skepticism and conclude with directions for future research. (shrink)

I give an interpretation according to which Meno’s paradox is an epistemic regress problem. The paradox is an argument for skepticism assuming that acquired knowledge about an object X requires prior knowledge about what X is and any knowledge must be acquired. is a principle about having reasons for knowledge and about the epistemic priority of knowledge about what X is. and jointly imply a regress-generating principle which implies that knowledge always requires an infinite sequence of known reasons. Plato’s response (...) to the problem is to accept but reject : some knowledge is innate. He argues from this to the conclusion that the soul is immortal. This argument can be understood as a response to an Eleatic problem about the possibility of coming into being that turns on a regress-generating causal principle analogous to the regress-generating principle presupposed by Meno’s paradox.

This paper provides an interpretation of Aristotle’s criticism to the solution to Meno’s Paradox suggested by Plato. According to Aristotle, when Plato says that reminiscence (anámnēsis) is achieved, what is actually achieved is induction (epagōgê). Our interpretation is based on two aspects: (1) semantic criticism, since Plato’s use of the term anámnēsis is unusual; and (2) the theory is not able to give an adequate explanation of the effective discovery.

Review of Gail Fine, The Possibility of Inquiry (OUP 2014).

I argue that Meno’s Paradox targets the type of knowledge that Socrates has been looking for earlier in the dialogue: knowledge grounded in explanatory definitions. Socrates places strict requirements on definitions and thinks we need these definitions to acquire knowledge. Meno’s challenge uses Socrates’ constraints to argue that we can neither propose definitions nor recognize them. To understand Socrates’ response to the challenge, we need to view Meno’s challenge and Socrates’ response as part of a larger disagreement about the value (...) of inquiry. (shrink)

We simply cannot make sense of Socrates' procedure for cross-examining his interlocutors in the early dialogues if we insist that Socrates uses cross-examination only for the purpose of testing his interlocutor's claim to knowledge. This view of Socratic cross-examination cannot explain the fact that Socrates examines theses that he himself proposes and that neither he nor his interlocutor explicitly endorses. In contrast,the supposition that Socrates is inquiring on these occasions provides a good explanation for his procedure. When one is attempting (...) to gain true belief and knowledge, it is important to consider the cases that can be made for hypotheses that one has never before considered, much less believed to be true.

This work articulates two thesis: one Socratic and one Platonic; and displays how the first one is heir of the second. The Socratic one is called the principle of priority of definition; the Platonic one is the Recollection theory. The articulation between both theses is possible due to the Meno’s paradox, which makes a criticism on the first thesis, but it is solved with the second one. The consequence of this articulation is a new interpretation of the Recollection theory, as (...) a theory of knowledge acquisition that depends, mainly, on a distinction between knowledge and true opinion. To conclude, a new interpretation of the knowledge/true opinion distinction is displayed –not in the traditional fashion, evaluating the propositions one by one, and in an atomic way–, but as big blocks or chains of propositions shaping knowledge through explanatory reasoning (aitías logismós).

Plato articulates a deep perplexity about inquiry in ?Meno's Paradox??the claim that one can inquire neither into what one knows, nor into what one does not know. Although some commentators have wrestled with the paradox itself, many suppose that the paradox of inquiry is special to Plato, arising from peculiarities of the Socratic elenchus or of Platonic epistemology. But there is nothing peculiarly Platonic in this puzzle. For it arises, too, in classical Indian philosophical discussions, where it is formulated with (...) great clarity, and analysed in a way that casts it in a new light. We present three treatments of the puzzle in Indian philosophy, as a way of refining and sharpening our understanding of the paradox, before turning to the most radical of the Indian philosophers to tackle it. The Indian philosophers who are optimistic that the paradox can be resolved appeal to the existence of prior beliefs, and to the resources embedded in language to explain how we can investigate, and so move from ignorance to knowledge. Highlighting this structural feature of inquiry, however, allows the pessimist philosopher to demonstrate that the paradox stands. The incoherence of inquiry is rooted in the very idea of aiming our desires at the unknown. Asking questions and giving answers rests on referential intentions targeting objects in a region of epistemic darkness, and so our ?inquiry sceptic? also finds structurally similar forms of incoherence in the pragmatics of interrogative discourse.

Psiche sets up a close-knit comparison between the psychology of Plato's Republic and Freud's psychoanalysis. Convergences and divergences are discussed in relation both to the Platonic conception of the oneiric emergence of repressed desires that prefigures the main path of Freud's subconscious, to the analysis of the psychopathologies related to these theoretical formulations and to the two diagnostic and therapeutic approaches adopted. Another crucial theme is the Platonic eros - the examination of which is also extended to the Symposium and (...) Phaedrus - taken up explicitly by Freud in relation to the concept of libido.

Altro tema cruciale è l'eros platonico - la cui disamina viene estesa anche al "Simposio" e al "Fedro" - ripreso esplicitamente da Freud in relazione al concetto di libido.

Plato’s invention of the metaphor of carving the world by the joints (Phaedrus 265d-66c) gives him a privileged place in the history of natural kind theory in philosophy and science; he is often understood to present a paradigmatic but antiquated view of natural kinds as possessing eternal, immutable, necessary essences. Yet, I highlight that, as a point of distinction from contemporary views about natural kinds, Plato subscribes to an intelligent-design, teleological framework, in which the natural world is the product of (...) craft and, as a result, is structured such that it is good for it to be that way. In Plato’s Philebus, the character Socrates introduces a method of inquiry whose articulation of natural kinds enables it to confer expert knowledge, such as literacy. My paper contributes to an understanding of Plato’s view of natural kinds by interpreting this method in light of Plato’s teleological conception of nature. I argue that a human inquirer who uses the method identifies kinds with relational essences within a system causally related to the production of some unique craft-object, such as writing. As a result, I recast Plato’s place in the history of philosophy, including Plato’s view of the relation between the kinds according to the natural and social sciences. Whereas some are inclined to separate natural from social kinds, Plato holds the unique view that all naturalness is a social feature of kinds reflecting the role of intelligent agency. (shrink)

Plato’s Sophist and Statesman stand out from many other Platonic dialogues by at least two features. First, they do not raise a ti esti question about a single virtue or feature of something, but raise the questions what sophist, statesman, and philosopher are, how they differ from each other, and what worth each should be accorded. Second, a visitor from Elea, rather than Socrates, seeks to addressed these questions and does so by employing what is commonly referred to as the (...) method of collection and division. Some scholars have argued that this so-called method is value neutral and therefore unable to address the question how philosophy differs from sophistry and statesmanship according to worth. This article contends that the procedures of collection and division does not preclude the visitor from taking considerations of worth into account, but rather helps establish an objective basis for settling the main questions of the dialogue.

This paper examines whether Socrates provides his interlocutors with good reasons to seek knowledge of what virtue is, reasons that they are in a position to appreciate. I argue that in the Laches he does provide such reasons, but they are not the reasons that are most commonly identified as Socratic. Socrates thinks his interlocutors should be motivated not by the idea that virtue is knowledge nor by the idea that knowledge is good for its own sake, but rather by (...) the idea that knowledge is needed to recognize what to aim at. His argument reaches the potentially life-altering conclusion that we should all seek knowledge of what virtue is. It is powerful precisely because it relies on uncontroversial premises that his interlocutors could be expected to accept. In laying out this argument, I distinguish different ways in which someone could count as a teacher of virtue. At the end of the article, I situate the argument within the debate about whether virtue is teachable. (shrink)

A review of John Beversluis' "Cross-Examining Socrates: A Defense of the Interlocutors in Plato's Early Dialogues".

Different reasons give rise to the question, what philosophy really is, and by tradition we know many answers. Plato’s answer can be found by examining his explicit statements about philosophy in his dialogues, or by analyzing his representation of Socrates – philosophy become fl esh. But an other way to fi nd an answer to the question lies in examining the things which – according to Plato – we cannot do without. There are three of them, namely the idea, logos (...) and aporia. These three taken together – the insight that we orient ourselves according to some unity in our different fi elds of life; that we cannot dismiss dialogue and debate; and questions outlive answers – paint a picture of philosophy as «unbehauptendes Denken»1 [undogmatic thought]. Such «unbehauptendes Denken» does not aim to insist on new claims against old ones, but instead seeks to analyze and to refl ect upon old views. (shrink)

I argue that Meno’s Paradox targets the type of knowledge that Socrates has been looking for earlier in the dialogue: knowledge grounded in explanatory definitions. Socrates places strict requirements on definitions and thinks we need these definitions to acquire knowledge. Meno’s challenge uses Socrates’ constraints to argue that we can neither propose definitions nor recognize them. To understand Socrates’ response to the challenge, we need to view Meno’s challenge and Socrates’ response as part of a larger disagreement about the value (...) of inquiry. (shrink)
