I develop the relatively familiar idea of a variety of forms of knowledge —not just propositional knowledge but also knowledge -how and experiential knowledge —and show how this variety can be used to make interesting sense of Plato’s and Aristotle’s philosophy, and in particular their ethics. I then add to this threefold analysis of knowledge a less familiar fourth variety, objectual knowledge, and suggest that this is also interesting and important in the understanding of Plato and Aristotle.

En este trabajo intento mostrar que la función de la doctrina heraclítea en el Teeteto es argumentar a favor de la equivalencia entre la tesis de Protágoras y la definición de Teeteto “la percepción es conocimiento”, y que de esta manera la doctrina apoya la relatividad del conocimiento. Esta lectura va en contra de quienes sostienen que Platón introduce la doctrina porque la cree correcta acerca de lo sensible, y va un paso más allá de la interpretación que afirma que (...) Platón introduce la doctrina como una tesis ontológica para apoyar la tesis de Protágoras. (shrink)

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.

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 argues for a possible-worlds interpretation of the arguments marshalled by Socrates against Protagoras in Plato’s Theaetetus. Specifically, it reads Protagoras’ position as implying a limited form of modal realism, and evaluates both the self-refutation sequence at 170a–71d and the Future Argument at 177c–9c on the basis of this reading. It emerges that Socrates’ project is only partly successful: while the three main arguments of the self-refutation sequence force Protagoras into ever more awkward and metaphysically top-heavy positions, and the (...) Future Argument is psychologically compelling, these arguments do not force a collapse of the relativist position. Protagoras can still defend himself, though the cost is high. (shrink)

Socratic irony can be understood independently of the immortal heroics of Plato’s Socrates. We need a systematic account and criticism of it both as a debate-winning strategy of argumentation and teaching method. The Speaker introduces an issue pretending to be at a lower intellectual level than her co-debaters, or Participants. An Audience looks over and evaluates the results. How is it possible that the Speaker like Socrates is, consistently, in the winning position? The situation is ironic because the Participants fight (...) from a losing position but realize it too late. Socratic irony compares with divine irony: divine irony is a subtype of Socratic irony since you lose when you challenge gods. Socratic irony is also, prima facie, a subtype of dramatic irony when the Audience knows more than the Participants on the stage. We must distinguish between the ideal and realistic elements of Socratic Irony. The very idea of Socratic irony looks idealized, or it is an ideal case, which explains the Speaker’s consistently winning position. In real life, the debate must be rigged, or the Dutch Book argument applies to the Participants, if the Speaker is so successful. (shrink)

This paper argues for the presence in Plato’s work of a conception of thinking central to which is what I call the Transparency View. According to this view, in order for a subject to think of a given object, the subject must represent that object just as it is, without inaccuracy or distortion. I examine the ways in which this conception influences Plato’s epistemology and metaphysics and explore some ramifications for contemporary views about mental content.

In this paper, I examine several key issues relating to the definition of knowledge as perception in the first part of Plato's Theaetetus. I begin by explaining the workings of the ‘secret doctrine’ of perception, which is introduced in order to support the idea that perception is incorrigible, and then turn to examine the two refutations of the definition of knowledge as perception which appear at the end of the first part of the Theaetetus. I shall present and explain distinct (...) lines of interpretation pertaining to these passages and explore the consequences they attempt to draw regarding Plato's views on the perceptual world, the nature of perception and how these bear on his conception of knowledge.

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.

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.

This article updates “The State of the Question in the Study of Plato” (Southern Journal of Philosophy, 1996) based on research covering the years from 1995–2015. Its three major parts examine: (1) how the mid‐twentieth‐century consensus has fared, (2) whether the new trends identified in that article have continued, and (3) identify trends either new or missed in the original article. On the whole, it shows the continuing decline of dogmatic and nondramatic Plato interpretation and the expansion and ramification of (...) the more literary, dramatic, and nondogmatic “new Platonism.” What was a growing insurgency twenty years ago can now be described as a, if not the, dominant approach.

Movement and, more particularly, kinesthesia as a modality and as a metaphor has become of interest at the intersection of phenomenology and cognitive science. In this paper I wish to combine three historically related strands, aisthêsis, kinesthesis and aesthetics, to advance an argument concerning the aesthetic value of certain somatic sensations. Firstly, by capitalizing on a recent regard for somatic or inner bodily senses, including kinesthesia, proprioception and the vestibular system by drawing lines of historical continuity from earlier philosophical investigations (...) on bodily background experience, initially from aisthêsis, Aristotle’s concept of the sensory faculty. Secondly, concepts of the sensate body are advanced through discoveries in the nervous system and related discussions of the ‘inner’ senses such as Charles Bell’s ‘muscle sense’ (1826), and what Charles Sherrington later termed ‘proprio-ception’ (1906). Thirdly, we consider the possibility of aesthetic status for those inner senses, where recently aesthetic arguments by Montero (2006) and Cole and Montero (2007) seek to determine aesthetic criteria for proprioception, and similarly in dance theory the aesthetic status of kinesthesia has been questioned (e.g. Foster 2011). Finally we consider whether previous exposure to a ‘grammar’ of movement is a factor in determining the relative aesthetic value. (shrink)

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.

The digression of Plato’s Theaetetus (172c2–177c2) is as celebrated as it is controversial. A particularly knotty question has been what status we should ascribe to the ideal of philosophy it presents, an ideal centered on the conception that true virtue consists in assimilating oneself as much as possible to god. For the ideal may seem difficult to reconcile with a Socratic conception of philosophy, and several scholars have accordingly suggested that it should be read as ironic and directed only at (...) the dramatic character Theodorus. When interpreted with due attention to its dramatic context, however, the digression reveals that the ideal of godlikeness, while being directed at Theodorus, is essentially Socratic. The function of the passage is to introduce a contemplative aspect of the life of philosophy into the dialogue that contrasts radically with the political-practical orientation characteristic of Protagoras, an aspect Socrates is able to isolate as such precisely because he is conversing with the mathematician Theodorus.

In this paper I argue that in the digression in Plato’s Theaetetus godlikeness may be construed as Socrates’ ethical achievement, part and parcel of his art of mental mid­wifery. Although the philosophical life of contemplation and detachment from earthly affairs exemplifies the human ideal of godlikeness, Socrates’ godlikeness is an inferior but legitimate species of the genus. This is the case because Socratic godlikeness abides by the two requirements for godlikeness that Socrates sets forth in the digression: first, it is (...) a kind of escape from the phenomenal world; and second, it allows Socrates to become just and pious with wisdom. The crucial difference between Socrates and the philosopher that prevents the former from being as godlike as the latter is his epistemic barrenness, on account of which he cannot define the constitutive virtues of godlikeness, i.e., justice, piety, and wisdom. As a barren midwife of the intellect, Socrates practices godlikeness but does not have a philosophical understanding of its nature. Nevertheless, by extolling the life of the philosopher he urges others to aspire to what he can never attain, philosophical godlikeness. (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.
