Corrective intervention in Plato's metaphysics replacing the standard view of Plato as a metaphysical dualist with a novel and revolutionary paradigm of unitary pluralism in a single reality built on ontological diversity.

At a crucial juncture in Plato’s Sophist, when the interlocutors have reached their deepest confusion about being and not-being, the Eleatic Visitor proclaims that there is yet hope. Insofar as they clarify one, he maintains, they will equally clarify the other. But what justifies the Visitor’s seemingly oracular prediction? A new interpretation explains how the Visitor’s hope is in fact warranted by the peculiar aporia they find themselves in. The passage describes a broader pattern of ‘exploring both sides’ that lends (...) insight into Plato’s aporetic method. (shrink)

In general, scholars have viewed the mathematical detail of Plato’s Divided Line discussion in Republic VI-VII as irrelevant to the substance of his epistemology.Against this stance this essay argues that this detail serves a serious and instructive purpose and makes manifest some central features of Plato’s account of human knowledge.

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief has it if and only if it (...) has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

Investigating Plato’s ontological as well as epistemological status in each of his dialogues, this book is going to challenge the current theories of Plato’s development and suggest a new one. Regarding the relation of Plato’s early and middle period dialogues, scholars have been divided to two opposing groups: unitarists and developmentalists. While developmentalists try to prove that there are some noticeable and even fundamental differences between Plato’s early and middle period dialogues, the unitarists assert that there is no essential difference (...) in there. The main goal of the first two chapters is to suggest that some of Plato’s ontological as well as epistemological principles change, both radically and fundamentally, between the early and middle period dialogues. Though this is a kind of strengthening the developmentalistic approach corresponding the relation of the early and middle period dialogues, based on the fact that what is to be proved here is a essential development in Plato’ ontology and his epistemology, by expanding the grounds of development to the ontological and epistemological principles, it hints to a more profound development. The fact that the bipolar and split knowledge and being of the early period dialogues give way to the tripartite and bound knowledge and benig of the middle period dialogues indicates the development of the notions of being and knowledge in Plato’s philosophy before the dialogues of the middle period. The first chapter entitled “Plato’s Onto-Epistemological Principles in the Early Dialogues” tries to draw out six principles out of Plato’s early dialogues specially Euthyphro, Laches, Charmides, Hippias Major and Euthydemus. We discuss that these principles present kind of a bipolar as well as split ontology and epistemology. The second chapter, “Revision of First Socrates’ Principles in the Middle Period Dialogues”, aims to argue that the onto-epistemological principles of the early dialogues are being radically changed in three dialogues of Meno, Phaedo and Republic in the middle period dialogues. Not only the bipolar ontology and epistemology of the early dialogues give place to a tripartite ontology and epistemology but also their split being and knowledge are inclined to be replaced by bound being and knowledge. Our next step in this book is to suggest a new approach to Plato’s theory of being in Republic V and Sophist based on the notion of difference and the being of a copy. To understand Plato’s ontology in these two dialogues we are going to suggest a theory we call Pollachos Esti; a name we took from Aristotle’s pollachos legetai both to remind the similarities of the two structures and to reach a consistent view of Plato’s ontology. Based on this theory, when Plato says that something both is and is not, he is applying difference on being which is interpreted here as saying, borrowing Aristotle’s terminology, 'is is (esti) in different senses'. I hope this paper can show how Pollachos Esti can bring forth not only a new approach to Plato’s ontology in Sophist and Republic but also a different approach to being in general. Thence, chapter three, “Pollachos Esti; Plato’s Ontology in Sophist and Republic”, intends to discuss that i) the theories of ‘being as difference’ and ‘being of a copy’, considered together in what we call the theory of pollachos esti, can well be compared to the structure of pollachos legetai in Aristotle when it is attached to the theories of pros hen and substance; and ii) the ontology of Republic V-VII is based on this theory and is, thus, almost the same as the ontology of Sophist. Investigating the most famous chronologies of the last 150 years from Campbell on, the fourth chapter, “The Standard Chronology of the Dialogues”, is to argue that all of them have a somewhat fix and dogmatic arrangement of Plato’s dialogues in which Meno, Phaedo and Republic are located after some early dialogues and before Theaetetus and Parmenides, on the one hand, and all the so-called late period dialogues after Theaetetus and Parmenides on the other hand. It is also reminded that all that the stylometric evidences can show is the lateness and homogeneity of the late period dialogues and, thence, nothing about the relation between dialogues like Theaetetus, Parmenides and Republic. The standard chronology is the subject of many criticisms some of which are discussed in our fifth chapter, “Objections against the Standard Chronology”, in three groups. While the first group of objections criticizes the place of the middle period dialogues immediately after the early ones, the second group attacks the place of late dialogues after the middle ones. The third group includes objections against the place of Parmenides in the standard chronology and tries to show that it cannot be considered after the middle period dialogues. The efforts of the first five chapters lead to a new theory of Plato’s ontological as well as epistemological development in an onto-epistemological chronology of his dialogues in our sixth chapter, “An Onto-Epistemological Chronology of Plato’s dialogues”. Instead of three periods, this chronology includes four waves of dialogues, Socratic wave, ontological wave, epistemological wave and political wave, in which all the so-called middle and late period dialogues are to be interpreted based on the problems presented in Parmenides I. The main changes we suggest in the standard chronology include firstly that Theaetetus and Parmenides I must be posited before Meno and Phaedo and, secondly, Republic must be posited after Sophist. Based on this arrangement, we can find Philosophos, Plato’s promised but unwritten dialogue, inside Republic. (shrink)

Plato scholars such as Matthias Baltes (1940-2003) and Luc Brisson have defended the thesis that Plato‘s Idea of the Good is on the one hand beyond being (epekeina tês ousias) in dignity and power, but is nevertheless not transcendent over being. The article gives first (I.), an introduction into the status questionis. Second (II.), it delivers the most important arguments for the thesis of Baltes and Brisson. Third (III.), it gives two counterarguments against the thesis. Fourth (IV), it deals with (...) the translation of L. Brisson "Apollon, quelle merveilleuse emphase" of 509c1-2. Fifth (V.), it concludes with some general questions concerning the deflationist interpetation of Plato‘s Republic, 509b9-10. (shrink)

How can we acquire understanding? Linda Zagzebski has long claimed that understanding is acquired through, or arises from, mastering a particular practical technê. In this paper, I explicate Zagzebski’s claim and argue that the claim is problematic. Based on a critical examination of Zagzebski’s claim, I propose, in conclusion and in brief, a new claim regarding the acquisition of understanding.

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.

An existential reading of ‘is’ in the argument at Republic 476–480 is widely thought to be objectionable because it commits Plato to belief in degrees of existence. In this paper, I argue that neither proposed alternative—the veridical reading or the predicative reading—can be reconciled with the text, thus forcing the existential reading upon us. Further, I show that when Plato's doctrine of existence is properly understood, his commitment to degrees of existence is not at all absurd.

The article resonates Plato's ideas on education and art. In the Apology, Socrates describes his life's mission of practicing philosophy as aimed at getting the Athenians to care for virtue; in the Gorgias, Plato claims that happiness depends entirely on education and justice; in the Protagoras and the Meno, he puzzles about whether virtue is teachable or how else it might be acquired; in the Phaedrus, he explains that teaching and persuading require knowledge of the soul and its powers, which (...) requires knowledge of what objects the soul may act on and be acted on by which, in turn, requires knowledge of nature. The article also looks at musical and gymnastic education's effects on the soul using images from metallurgy and dyeing wool, saying that prerational souls are “most malleable and take on any pattern one wishes to impress on them.”.

This article offers a new formulation of the Socratic principle known as the Principle of the Sovereignty of Virtue. It is divided in three sections. In the first section I criticize Vlastos’ formulation of the PSV. In the second section I present the weighing model of practical deliberation, introduce the concepts of reason for action, simple reason, sufficient reason and conclusive reason that were offered by Thomas Scanlon in Being realistic about reasons, and then I adapt these concepts so as (...) to render them apt to be used in the formulation I intend to offer. In the third section I present my formulation of the PSV using the concepts introduced in the second section and explain why I believe this formulation is better than the one offered by Vlastos.

Prior to the nineteenth century, those who are now regarded as scientists were referred to as natural philosophers. With empiricism, science was claimed to be a superior form of knowledge to philosophy, and natural philosophy was marginalized. This claim for science was challenged by defenders of natural philosophy, and this debate has continued up to the present. The vast majority of mainstream scientists are comfortable in the belief that through applying the scientific method, knowledge will continue to accumulate, and that (...) claims to knowledge outside science apart from practical affairs should not be taken seriously. This is referred to as scientism. It is incumbent on those who defend natural philosophy against scientism not only to expose the illusions and incoherence of scientism, but to show that natural philosophers can make justifiable claims to advancing knowledge. By focusing on a recent characterization and defense of natural philosophy along with a reconstruction of the history of natural philosophy, showing the nature and role of Schelling’s conception of dialectical thinking, I will attempt to identify natural philosophy as a coherent tradition of thought and defend it as something different from science and as essential to it, and essential to the broader culture and to civilization.

Plato gives us two model philosophical figures, apparently in contrast with each other—one is the otherworldly philosopher who sees truth and reality outside the cave and has the knowledge to rule authoritatively within it; the other is the demotic figure of Socrates, who insists that he does not know but only asks questions. I consider Plato’s contrasting idioms of seeing and asking or talking, and argue that the rich account of perception that is represented in the Republic requires both idioms, (...) and both models, to explain the development of epistemic virtue. Furthermore, the conditions he places on the giving and taking of reasons show how Plato takes intellectual virtue to be inseparable from moral virtue. That integrated picture of virtue may—however disposed we may be towards the role of virtue in either ethics or epistemology—have something to say to us about how philosophy might best be carried on.

In his dialogues, Plato presents different ways in which to understand the relation between Forms and particulars. In the Symposium, we are presented with yet another, hitherto unidentified Form-particular relation: the relation is Love (Erôs), which binds together Form and particular in a generative manner, fulfilling all the metaphysical requirements of the individual’s qualification by participation. Love in relation to the beautiful motivates human action to desire for knowledge of the Form, resulting in the lover actively cultivating and bringing into (...) being new beauty in the world, and in herself. Chapters 1 and 2 of this thesis offer a survey of the arguments and examples Plato puts forward in the text of the corpus regarding the nature of Forms and the nature of participation, alongside a framework of the traditional interpretations of these two Platonic concepts in the literature. Chapter 3 turns to a close examination of Erôs in the Symposium, arguing that the love Plato presents in this dialogue is of a different sort than appetitive emotion. It is an aesthetic and intellectual attraction, capable of stimulating cognitive achievement. Erôs, however, does not stop there. The lover is led not only to contemplation of beauty, but to the generation of beauty, which is the subject of Chapter 4. The emotive-turn-to-cognitive relation of Erôs, I argue, is the clearest picture Plato paints of how possession of properties can be explained through participation in Forms. Erôs leads the lover to produce beauty in the world and in the soul, which explains how love in relation to the beautiful can lead to becoming beautiful. The object of love is the generation of beauty, the mortal mechanism of participation in the Form by which the lover herself becomes beautiful. Finally, Chapter 5 focusses on beauty itself and its role in moral education. Beauty, for Plato, is required for creative generation and can be understood as a uniquely powerful virtue of soul.

This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

Epistemology today centrally concerns the conceptual analysis of knowledge. Historically, however, this is a concept that philosophers have seldom been interested in analysing, particularly when it is construed as broadly as the English language would have it. Instead, the overriding focus of epistemologists over the centuries has been, first, to describe the epistemic ideal that human beings might hope to achieve, and then go on to chart the various ways in which we ordinarily fall off from that ideal. I discuss (...) in detail two historical manifestations of idealized epistemology — Aristotle and Descartes — and then consider how this perspective might make a difference to the discipline today. In the end, an idealized epistemology points toward a normative, prescriptive rather than descriptive enterprise. (shrink)

My dissertation is a reading of Plato’s Timaeus that centers sexual difference and in particular femininity. I analyze the role of sexual difference in the framing of the dialogue as well as its accounts of body in the first and second discourse and its account of health in the third discourse. I argue that sexual difference, and, in particular, sexual reproduction, serves as a guiding paradigm of Timaeus’ entire project. I argue in each part of my dissertation that various aspects (...) of the Timaeus depend on a certain notion of sexual difference—even aspects which are seemingly causally prior to the issue of sexual difference (e.g., the nature of cause itself, structure). The dissertation consists of three parts. In the first part of my dissertation, I give a new reading of the myth of the origin of women at the end of the Timaeus and bring it into conversation with the dialogue’s opening in order to give an interpretation of the dialogue’s framing. I analyze the concept of sexual difference presented in this myth and argue that its philosophical richness has been overlooked, with many considering it to be either a joke or a sexist account. Focusing on Timaeus’s account of the woman’s relationship with her womb, I argue that womanhood in this myth is constituted by features that are elsewhere characterized as essentially philosophical (e.g., collaboration, making room, recognizing the complex structure of things, and nurture). In the second part of my dissertation, I introduce the two paradigms for the origin and composition of the cosmos in the Timaeus: the first discourse’s craft paradigm that construes the cosmos as a crafted artifact, and the second discourse’s genetic paradigm that construes the cosmos as a birthed organism. I am especially concerned with each discourse’s account of body. Here, I argue that the second discourse’s genetic paradigm is a significant revision of the first discourse’s craft paradigm. While some scholars have found that Timaeus’s insights in the second discourse are a further development of the groundwork he lays in the first discourse, I argue that the genetic paradigm’s focus on femininity and the mutual collaboration of masculine and feminine capacities is incompatible with the craft paradigm’s androcentrism. Finally, in the third part of my dissertation, I analyze the way that the Timaeus centers women’s bodies in its account of health in body and soul. Here, I argue that the Timaeus characterizes health by drawing on ideas about women’s bodies that are framed as symptoms of feminine disease in the Hippocratic texts (e.g., disequilibrium, flux, and porosity). Taken together, the three articles of my dissertation constitute a reading of the role of sexual difference in each part of the Timaeus. (shrink)

In White Noise by Don DeLillo, two characters visit a famous barn, described as the “most photographed barn in America” alongside hordes of picture-taking tourists. One of them complains the barn has become a simulacrum, so that “no one sees” the actual barn anymore. This implies that there was once a real barn, which has been lost in the “virtual” image. This is in line with Plato’s concept of the simulacrum as a false or “corrupt” copy, which has lost all (...) connection with the “original.” Plotinus, however, offered a different definition: the simulacrum distorts reality in order to reveal the invisible, the Ideal. There is a real building which has been called “the most photographed barn in America”: the Thomas Moulton Barn in the Grand Teton National Park. The location—barn in the foreground, mountain range towering over it—forms a striking visual composition. But the site is not only famous because it is photogenic. Images of the barn in part evoke the heroic struggles of pioneers living on the frontier. They also draw on the tradition of the “American sublime.” Ralph Waldo Emerson defined the sublime as “the influx of the Divine mind into our mind.” He followed Plotinus in valuing art as a means of “revelation”—with the artist as a kind of prophet or “seer.” The photographers who collect at the Moulton Barn are themselves consciously working within this tradition, and turning themselves into do-it-yourself “artist-seers.” They are the creators, not the slaves of the simulacrum.

According to a historical claim oft-repeated by contemporary epistemologists, the ‘traditional’ conception of knowledge prevailed in Western philosophy prior to the publication in 1963 of Edmund’s Gettier’s famous three-page article ‘Is Justified True Belief Knowledge?’. On this conception, knowledge consists of justified true belief. In this article, I critically consider evidence for and against this historical claim, and conclude with a puzzle concerning its widespread acceptance.

In Republic V, Plato distinguishes two different cognitive powers, knowledge and belief, which operate differently on different types of object. I argue that in Republic VI Plato modifies this account, and claims that there is a single cognitive power, which under different circumstances behaves either as knowledge or as belief. I show that the circumstances which turn true belief into knowledge are the provision of an individuation account of the object of belief, which reveals the ontological status and the nature (...) of the object. Plato explores many alternative candidates of individuation accounts of objects of true belief, which he discards. I conclude with a Platonic sketch of a teleological account of individuation which would satisfy his requirements of turning true belief into knowledge. (shrink)

Traditionally, the debate between epistemological internalists and externalists has centered on the value of knowledge and its justification. A value pluralist, virtue-theoretic approach to epistemology allows us to accept what I shall call the insight of externalism while still acknowledging the importance of internalists’ insistence on the value of reflection. Intellectual virtue can function as the unifying consideration in a study of a host of epistemic values, including understanding, wisdom, and what I call articulate reflection. Each of these epistemic values (...) is a good internal to inquiry. Thus, an inquiry-based conception of virtue is particularly well suited to help us account for a wide variety of epistemic goods, without reducing the value of those many goods to their contribution to the value of knowledge. Moreover, an inquiry-based conception of virtue can function as the unifying consideration in a general study of value, the scope of which is not restricted to epistemic value. (shrink)

A discussão nos livros dos Tópicos giram em torno dos debates dialéticos e seus elementos. Aristóteles discorre sobre os gêneros, as propriedades e os chamados acidentes e suas relações predicativas em categorias.

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)

Plato decided that the poets, that is, all creative writers, should be banned from his ideal state. He objected to the claim that they imparted knowledge to their audiences. The poets gave no explanation of the basis for the stories that they told or the conclusions to which those stories led. Plato denied the validity of any claim to knowledge that was not accompanied by an account that justified the claim. Management scholars make comparable objections to management consultants. They argue (...) that consultants use rhetoric and story-telling to persuade clients of their knowledge, when their services often have no foundation in real knowledge. Consultancy knowledge is to a large extent socially constructed, dependent for its status as knowledge on clients’ acceptance of it as such. Consultants often sell their services and persuade clients of their value by appealing to their relevance to passing management fashions and fads. The poets necessarily are susceptible to Plato’s objections, because they are creative artists whose proper business is primarily to entertain rather than to impart knowledge. By contrast, consultants have a clear role in imparting and applying management knowledge. They should respond to management scholars’ objections by shifting their focus ever more sharply towards the technoeconomic contributions that consultants can make to their clients, and away from the use of rhetoric and story-telling to promote their services.
