Plato: Knowledge and Belief

Limits of the Conversation about Forms. Types of Knowledge and Necessity of Forms in Plato's "Parmenides". - Forms (ideas) are among the things that Plato is serious about. But about these things he says in his "Seventh Letter": "There neither is nor ever will be a treatise of mine on the subject." (341c, transl. J. Harward). Plato's statement suggests the question, why one does not and never can do justice to the Platonic forms by means of a written text about (...) the forms. Another big question of Plato research is whether the conversations documented in the Platonic dialogues are also affected by this verdict. This paper aims to provide, as far as possible, newly substantiated answers to these two questions. To this end, the systematic limits of the discussion about forms, which are particularly evident in Plato's dialogue "Parmenides", are examined in eight steps: First, two types of knowledge are presented that play an important systematic role in Plato's philosophy with regard to the limits of conversation: knowledge-how (practical knowledge) and knowledge-that (propositional knowledge) (I). Then the Socratic model of these two types of knowledge is interpreted, which is drafted in the tenth book of the "Republic". This model uses the example of bridle, bridlemaker and rider to explain the primacy of practical knowledge and the limits of propositional knowledge (II). Subsequently, it will be shown how the dialogues "Republic" and "Parmenides" are connected with each other in content and form (III). The gradation of the two types of knowledge, which is indicated by the motifs of the bridle and the horse on the image level of the "Parmenides", proves to be the structure that systematically underlies the structure of the entire dialogue (IV). It also makes clear why the conversation about the forms in the first part of the "Parmenides" has to fail (V). The assumption that the two parts of the "Parmenides" express two different types of knowledge in dealing with forms is supported by the results of a logical analysis of the last defence of the acceptance of forms (135b-c). This analysis shows why, for reasons of principle, it is impossible to speak adequately about forms (VI). Forms have the function of being presuppositions of 'talking about something'. Thus forms are always presupposed in conversation when one talks about them, and thus elude appropriate discussion in conversation (VII). That this is not only a methodical insight of the Platonic Parmenides, but can also be attributed to Plato himself, is demonstrated by the concluding reinterpretation of the central sentence of the critique of writing in Plato's "Seventh Letter". It will become apparent that, contrary to the now widespread view of the representatives of the Tübingen school, philosophical and also good philological reasons speak for the fact that Plato related his criticism only to the communicability of forms through treatises, i.e. tract-like writings (VIII).

An account of Plato’s theory of knowledge is offered. Plato is in a sense a contextualist: at least, he recognizes that his own use of the word for “knowledge” varies – in some contexts, it stands for the fullest possible level of understanding of a truth, while in other contexts, it is broader and includes less complete levels of understanding as well. But for Plato, all knowledge, properly speaking, is a priori knowledge of necessary truths – based on recollection of (...) aspects of the Forms – and so in contemporary terms, it meets the conditions of “safety” and “adherence” (or “indefeasibility”) to the highest degree. This account is defended on the basis of the text of Meno, Phaedo, and the Republic, against some objections – especially objections that are due to Gail Fine. (shrink)

It is often claimed that Plato’s definition of knowledge as “true opinion with an account” is in agreement with the contemporary analysis of knowledge as “justified true belief”. Some scholars disagree with the attribution of JTB to Plato. I analyze three influential arguments against the assumption of Plato’s agreement with JTB, and refute them. Then I provide my own argument against the assumption. I argue that the contemporary interpretation of the JTB formula understands “belief” not in the sense of an (...) “opinion,” but rather of a “degree of confidence.” Accordingly, “justification” is understood not as applying to the opinion itself, but rather to the person having a certain degree of confidence. I support this claim by showing the difference between the traditional and the contemporary understanding of “evidence,” the former referring to a property of the proposition, while the latter meaning the body of reasons, which supports the person’s confidence to a certain degree. Thus, I conclude that Plato understands knowledge as “correct opinion validated by a rational explanation,” and it has very little in common with the contemporary understanding of knowledge as “sufficiently supported subjective degree of confidence in the truth of a proposition.”.

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)

In the Phaedo, Socrates endorses the view that the senses are not a means whereby we may come to gain knowledge. Whenever one investigates by means of the senses, one is deceived. One can attain truth only by inquiry through intellect alone. It is a measure of the success of empiricism that modern commentators take a very different approach to Phaedo 65a9-67b3 than their neoplatonist forebearers did. In what follows I shall argue that, if they made too much of "Socrate's" (...) anti-empiricism, we make too little of it.I believe that careful examination of the presuppositions of Socratic questioning will reveal some principled reasons which lead to the view about sense perception that Socrates endorses in the Phaedo. These reasons are, I believe, wrong and I think that Plato may have had occassion to reconsider them later in his career. But even if this is so, it remains that Socrates' anti-empiricism in this dialogue is not simply a gratuitous epistemological reflection of the dialogue's otherworldly, ascetic ethical outlook.

Possibility of falsehood arises in the early parts of plato's "sophist". I argue that the participants in the dialogue operate with two related analogies, one which considers spoken images to be fundamentally like seen images, and another analogy which considers the objects of stating or believing to be like the objects of perceiving. (the second analogy has parallels in "theaetetus" 188c-189b). These analogies lead to confusions which plato attempts to dispel in the later portions of the "sophist".

In this paper I explore a famous part of Plato’s Theaetetus where Socrates develops various models of the mind (picturing it first as a wax tablet and then as an aviary full of specimen birds). These are to solve some puzzles about how it is possible to make a mistake. On my interpretation, defended here, the discussion of mistakes is no digression, but is part of the refutation of Theaetetus’s thesis that knowledge is “true doxa”. It reveals that false doxa (...) is possible only if there is a certain stock of abstract knowledge, conceptual knowledge, that is not awareness of the particular individual that is being described. The individual must be identified under some description, or seen as something of a certain kind. Error can only occur if the description applied misdescribes the situation, but then if it is to be applied falsely it must first have been known from somewhere else. So knowledge cannot be reduced to the application of descriptions to particulars, but is to be found in the prior possession of abstract descriptions that can be deployed in identifying particular individuals on the ground.

I look at (I) the problem of false speech which Plato faces, (II) the solution he gives in the Sophist, and (III) how that very solution is undermined by the argument of the Theaetetus. I conclude that we ought to see the account of the Theaetetus as overruling the account of the Sophist. On this alternative, Plato holds that false speech and thought really is impossible.

This essay first differentiates the various meanings of the term as it appears in Plato's dialogues Theaetetus and The Sophist. These are: the colloquy of the soul with itself, a single sentence, a proposing aloud, the enumeration of the constitutive elements of a whole and the giving of a specific difference; further, opinion and imagination. These meanings are then related to Plato's determination of knowledge and therewith truth and falsity. One can be said to possess knowledge only when the universal (...) contents of thought - dialogical thought - are set in relation to the perceivable, imagination or opinion. Reflections on the principle significance of possibility as such - a thematic not addressed by Plato - conclude the essay. (shrink)

Plato's management based on its knowledge of the theory has been the focus of discussion, and scholars on how he sees little "knowledge" concept to make a note. This article is from the following two parts; the first section of Plato's concept of the right knowledge when knowledge is similar to the concept, such as Descartes; second part will discuss, for Plato, knowledge and understanding of the to the relationship between.

Plato provocatively characterizes truth $$ in terms of harmony $$ at various points throughout his dialogues. While limited attention has been directed toward the role of musical concepts in Plato's general cosmology, not any attention has been directed toward how musical concepts function in relation to Plato's characterization of truth. In fact, this issue has had little occasion for consideration. Almost every contemporary translator empties terms such as $\grave\alpha\rho\mu o\nu\acute\iota\alpha,$ when co-incidental with $\acute\alpha\lambda\acute\eta\theta\varepsilon\iota\alpha,$ of their musical content. As a consequence, (...) I argue, Plato's characterization of truth is made readily amenable to contemporary conceptions of truth-not necessarily a good thing since it robs us of the original richness of Plato's thought. The dissertation explores how retaining the aural meaning latent within $\grave\alpha\rho\mu o\nu\acute\iota\alpha$ and other terms of musical import serves to elucidate the rich complexion of Plato's notion of $\acute\alpha\lambda\acute\eta\theta\varepsilon\iota\alpha.$ Ultimately, I show how Plato's use of musical terminology to characterize truth informs other features of his philosophical outlook, illustrate the cohesiveness and consistency of key texts believed problematic by other commentators, and underscore significant differences between Plato's $\acute\alpha\lambda\acute\eta\theta\varepsilon\iota\alpha$ and ideas of truth prevalent today. ;For Plato, I argue $\acute\alpha\lambda\acute\eta\theta\varepsilon\iota\alpha$ bears a meaning different from its primitive sense of oracular unconcealment and its later sense of correctness $,$ and a meaning also different from other terminological alternatives $.$ Truth, accordingly, turns out for Plato to be neither mysterious and groundless nor a matter of simple correspondence to an objective reality. The value of Plato's conception of truth as harmony consists in its ability to avoid the polarity of contemporary conceptions of truth as either objectively determinate or subjectively determinate . Truth is neither arbitrarily imposed upon the world by us, nor artificially imposed upon us by an antecedently structured and independent reality. The dissertation concludes by articulating reasons for favoring Plato's theory of truth, while noting a few underlying assumptions likely problematic for some contemporary philosophers. (shrink)

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.

Guided by the bold ambition to reexamine the nature of philosophy, questions about the foundations and origins of Plato’s dialogues have in recent years gained a new and important momentum. In the wake of the seminal work of Andrea Nightingale and especially her book Genres in Dialogue from 1995, Plato’s texts have come to be reconsidered in terms of their compositional and intergeneric fabric. Supplementing important research on the argumentative structures of the dialogues, it has been argued that Plato’s philosophizing (...) cannot be properly assessed without considering its intellectual debts. By detailed examinations of the practical, generic and textual origins of the dialogues, it has been shown how Plato’s chosen form of philosophical inquiry is deeply influenced by traditional forms of poetry, rhetoric, sophistry, and even medicine...

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.
