The aim of this paper is to offer a general survey of the latest development of metaphysical idealism in contemporary Anglo-American philosophy. It consists of five main parts. The first part is a short introduction, it states the position of idealism and its current status in the Anglophone world. The second part focuses on the negative programme of idealism, which challenges physicalism on the problem of matter (2.1) and the problem of consciousness (2.2). The third part illustrates the positive programme (...) of idealism, whose varieties can be grouped into two principal types: constitutive and elementary. Constitutive idealism (3.1) is subdivided into the theocentric (3.1.1), the anthropocentric (3.1.2), and the acentric (3.1.3). Elementary idealism (3.2), on the other hand, can be unity-based (3.2.1), language-based (3.2.2), or knowledge-based (3.2.3). The six categories form a general framework of metaphysical idealism, and various accounts in the existing literature are discussed under each category. The fourth part addresses the relation between idealism and panpsychism. The paper is concluded with some caveats and future prospects. (shrink)

Plato argues that four political arts—politics, kingship, slaveholding, and household-management—are the same. His argument, which prompted Aristotle’s reply in Politics I, has been universally panned. The problem is that the argument clearly identifies household-management with slaveholding, and household-management with politics, but does not fully identify kingship with any of the others. I consider and reject three ways of saving the argument, and argue for a fourth. On my view, Plato assumes that politics is identical with kingship, just as he does (...) elsewhere, but he begs no questions because the point of his argument is to identify the public arts of politics and kingship with the private arts of household-management and slaveholding. He does this successfully by answering three reasons why one might distinguish the private from the public arts. His argument leaves room for Aristotle to propose other reasons. One of them—involving differences among men and women and slaves—is unfortunate, but another is more promising. The Aristotelian can assume that political expertise is a matter of know-how gathered by experience of the particular actions which differ in the public and private arts. But Plato might well be right to reject this, and to insist that the essential difference between the expert and non-expert—the dividing line between good and bad rule—is not in experience but in their grasp of their goals.

Aristotle was wont to say that most of those who heard Plato's Discourse on the Good had the following experience. Each came thinking he would be told something about one of the recognised human goods, such as Wealth, Health or Strength, or, in sum, some marvellous Happiness. But when it appeared that Plato was to talk on Mathematics and Numbers and Geometry and Astronomy, leading up to the statement that the Good was Unity, they were overwhelmed by the paradox (...) of the whole matter. Some then pooh-poohed the whole thing and others were outraged by it.1. (shrink)

The article argues for the following interpretation of Plato's dialogue Ion. (1) the dialogue is designed primarily to refute Ion's claims to knowledge in his discourse about Homer—i.e. in his role as critic or eulogist of Homer; (2) as regards the rhapsode as performer and as regards the poet, it is especially the fineness of their output that cannot be explained by way of techne; and (3) Plato genuinely assumes the existence of poetic and rhapsodic technai. Points (2) and (3) (...) are compatible. It is merely that excercising a techne is not the basis of artistic success (as we would now call it). The article argues that this reading gives the dialogue greater unity and philosophical plausibility than readings that deny any techne at all to either rhapsode or poet. (shrink)

The Parmenides is known as the dialogue in which Plato makes a criticism of his theory of forms. Through paradoxes, the character Parmenides criticizes the theory of forms presented by Socrates in the dialogue, targeting the relation they have with sensibles and with each other, call for participation, and the discoursive consequences of this relation. I present a reading of the Parmenides that suggests that the self-criticism points out inconsistencies in the Platonic theory of participation as it is presented in (...) the Parmenides, and that will be corrected later in the Sophist. (shrink)

The ancient quarrel between philosophy and poetry has a parallel in an equally ancient dispute between philosophy and history. Which is to be the great teacher, ideas, words, or deeds? In the education of the human race, particularly for political life, are we to think of the state as an ideal concept, as a work of art, or as an achievement of a person of action? These themes have exercised political thinkers as old as Plato and Aristotle and as modern (...) as Hobbes and Hegel, as well as perhaps the first modern, Niccolò Machiavelli. The issues of power, reason, and language, raised again and again in his masterpiece, The Prince, are equally central to the longer, less often read, but no less profound work, the Discourses on Livy, here given a loving and lucid translation, with a perceptive and helpful introduction, notes, glossary, and index. The Prince, usually taken as recommending absolute and ruthless individual sovereignty, is presumed to be the characteristic work of its author. The Discourses, with its recommendation of virtue and republicanism, on the other hand, is thought of as an inconsistent extravagation from the true Machiavellian position. However, as the translators make clear, this is textually and conceptually foreign to the facts. Machiavelli perhaps emphasizes the one set of values in the shorter book, and the other in the longer, but both are necessary to a full picture of his thought. The political problem for Machiavelli is balancing force with freedom. The unity of states is effected by force, their diversity by freedom. There is a problem of the one and the many in political theory as there is in other branches of philosophy. (shrink)

Plato invokes the Theory of Recollection to explain both ordinary and philosophical learning. In a new reading of Meno's Paradox and the Slave‐Boy Interrogation, I explain why these two levels are linked in a single theory of learning. Since, for Plato, philosophical inquiry starts in ordinary discourse, the possibility of success in inquiry is tied to the character of the ordinary comprehension we bring to it. Through the claim that all learning is recollection, Plato traces the knowledge achievable through inquiry (...) back to our pretheoretical comprehension, showing not just that knowledge is in us, but that it is inchoate in the grasp of a property—akin to a concept—that enables us to speak and think about it ordinarily. Plato acknowledges in the Meno that a second step of argument, and a second application of Recollection, is needed to explain how knowledge comes to be inchoate in our ordinary grasp of a property. Though this second argument is provided most fully in the Phaedo, the evidence of the Meno is sufficient to outline Recollection as a two‐stage theory of learning, beginning in ordinary speech and thought and extending, through philosophical reflection, to knowledge.

Socrates and Plato are one in species, but diverse in number. What accounts for their diversity in this sense? This question lies at the center of a longstanding controversy over what has been called the principle of individuation. Though multiple questions have been investigated using the terminology of individuation, the author’s focus here is on the question of what, for Aristotle, explains the numerical diversification of cospecific organisms, along with the two mainstream answers to this question: that their diversity derives (...) from the diversity of their matter, or that it derives from the diversity of their forms. She argues that if we take Aristotle’s metaontology as our starting point for investigating this question, both of the mainstream views falter for the same reason. Aristotle’s analyses of the concepts of unity and diversity support the conclusion that the diversity of cospecific organisms is underived. (shrink)

If philosophy weaves its speeches by distinguishing the basic elements of human experience and then collecting them into significant wholes, Dorter's wise book exemplifies the essential movement of philosophical thought. This polished, scholarly, insightful study explores the unity, not only of the four dialogues mentioned in its title, but in an important sense of the Platonic corpus as a whole. Dorter's fresh defense of the unorthodox view that in the so-called later dialogues Plato "retained the theory [of forms] in (...) all its essentials" constitutes an important contribution to Platonic studies. This is not all. The Plato that emerges from Dorter's study is no longer a primitive practitioner of modern techniques of analysis, but a thinker who challenges all of the major alternatives on the contemporary philosophical scene. In reacquainting us with the distinctive shape of Plato's metaphysics, Dorter opens up a possibility that is scarcely acknowledged in current philosophical discourse, namely, that "ontological thinking may lead to moral or spiritual transformation". His book will be of interest to anyone willing to entertain the idea that philosophy can improve the soul. (shrink)

Studies of Plato’s metaphysics have tended to emphasise either the radical change between the early Theory of Forms and the late doctrines of the Timaeus and the Sophist, or to insist on a unity of approach that is unchanged throughout Plato’s career. The author lays out an alternative approach. Focussing on two metaphysical doctrines of central importance to Plato’s thought – the Theory of Forms and the doctrine of Being and Becoming – he suggests a continuous progress can be (...) traced through Plato’s works. He presents his argument through an examination of the metaphysical sections of six of the dialogues: the Euthyphro, Phaedo, Republic, Parmenides, Timaeus, and Sophist. (shrink)

Plato's "laches" is an investigation into the nature of courage with the intention of demonstrating the difficulty of singling out one virtue, namely courage, and defining it separately from the other cardinal virtues such as bravery, wisdom, justice, temperance, and piety. As the dialogue proceeds it becomes evident that socrates not only relates courage with the battlefield, but also with other spheres of life. Of special interest is his reference of being courageous regarding desires and pleasures where an overlap of (...) virtues is anticipated. This extension of the range of manifestations of courage indicates that his conception of courage transcends the traditional one in which he hints at a new sort of unity of courage and temperance, and on the other of courage and justice. One of plato's main aims in writing this dialogue was to mark out the intellectual limits of the two generals' positions, especially that of nicias, whose philosophical position could appear to be deceptively similar to the socratic one which he did not fully understand.

Ostensibly a discussion about love, the debate in the Phaedrus also encompasses the art of rhetoric and how it should be practised. This new edition contains an introductory essay outlining the argument of the dialogue as a whole and Plato's arguments about rhetoric and eros in particular. The Introduction also considers Plato's style and offers an account of the reception of the dialogue from its composition to the twentieth century. A new Greek text of the dialogue is accompanied by a (...) select textual apparatus. The greater part of the book consists of a Commentary, which elucidates the text and makes clear how Plato achieves his philosophical and literary objectives. Primarily intended for advanced undergraduates and graduate students of ancient Greek literature and philosophy, it will also benefit scholars who want an up-to-date account of how to understand the text, argument, style and background of the work.

_The Being of the Beautiful_ collects Plato’s three dialogues, the _Theaetetus_, _Sophist_, and _Statesmen_, in which Socrates formulates his conception of philosophy while preparing for trial. Renowned classicist Seth Benardete’s careful translations clearly illuminate the dramatic and philosophical unity of these dialogues and highlight Plato’s subtle interplay of language and structure. Extensive notes and commentaries, furthermore, underscore the trilogy’s motifs and relationships. “The translations are masterpieces of literalness.... They are honest, accurate, and give the reader a wonderful sense of (...) the Greek.”—Drew A. Hyland, _Review of Metaphysics_. (shrink)

In Platonic dialogues the author’s reflections and intention are to be found not only in the statements of particular characters, but in the arrangement of the text as a whole. Not only does Plato decide what his main character says but he also chooses the reactions of his interlocutors, the progress and results of the conversation and whether his characters consider these results to be final answers. It seems that a Platonic dialogue could tell his reader more than what the (...) interlocutors tell each other. In my paper I try to reconstruct from discernible phenomena what the Meno is intended to tell us. My starting point is the question how the topics of this dialogue are connected with each other. Why did Plato present the question whether ἀρετή is teachable, the theory of recollection, the method of hypothesis and the distinction between knowledge and opinion in the same dialogue? Is the Meno to be considered as a collection of philosophical topics independent of each other, or did Plato see an interconnection between them? And how could this interconnection be described?

Professor Sallis has read the Apology, Meno, Phaedrus, Cratylus, Republic, and Sophist with the intention of elucidating Platonic responses to three questions: what is philosophy? what is logos? and what is being? His task, as he states it, is not to collect Plato’s opinions on these matters, as though such were either possible or interesting, but rather to elicit "an understanding of the manifold way in which a Platonic dialogue, by virtue of its character as a dialogue, lets whatever is (...) at issue in it become manifest." The actions described in the dialogues embody the results of the discourses recounted therein. The first part of the book, "Socratic Logos," attempts to clarify Plato’s answer to the first question by answering the far from obvious question "who was Socrates." The answer involves three points. First, the philosopher Socrates was aware of his own ignorance as well as the implicit limits of human wisdom; this "innate distance from a total and immediate revelation of beings" is, though, what motivates and makes possible the "second sailing" in logos described in the Phaedo. Athens’ obliviousness to the Apollonian origin of Socrates’ elenchtic [[sic]] activities led to its condemnation of him as a sophist. Second, the Meno’s myth of recollection "is founded on the capacity of man, with his peculiar mixture of knowledge and ignorance, to apprehend an image as an image, i.e., to apprehend the original that shows through it." The original, though, is the whole, of which the "manys" are images; the activity proper to the philosopher is recollection of the whole and mediation between whole and part. Third, Sallis’ work on the Phaedrus links Socrates’ divine mania and philosophic eros for the beautiful to his apprehension of eide. Sallis claims that the eidos of beauty is the most proper beginning for philosophic recollection of the eide because "the beautiful is that eidos which is most manifest to man in his embodied condition." The second half of the work poses the problem of the relation of being and logos. His excellently wrought study of the Republic accomplishes what several others in his exegetic tradition have failed to deliver: Sallis shows the actual engagement in what he calls "upward-moving dianoia" which Socrates compels Glaucon to undertake. Following Klein, Sallis stresses the unity of the "divided" line, though with this novel thesis: the distinction between "opinable" and "knowable" "is not fundamentally a distinction between two kinds of things, between which some relation would subsist, but rather between two ways in which an eidos can show itself... in both cases what shows itself is the same thing." He arrives at this by not wholly satisfying analyses of the mixture of beauty and ugliness in sensible things, and by reflection on the finger-example Socrates offers, at Rep. 523, ff. Concerning the good, Sallis’ judgment is that Socrates’ inexact analogy of it to the light of the sun means that it "makes possible that sort of showing in which something can show itself as one." The course of his exegesis and argument must be studied in detail, but whatever its lacunae, it does allow a good explanation of the unity of logoi and erga in this long dialogue, of its apparent abstraction from eros, and of its central images of sun, line, and cave. Sallis’ section on the Sophist lacks the precision and sureness of his work on the Republic. He continues, though, with his emphasis on the central importance of the study of the structure of images. Image-making raises the problem of non-being, which raises the problem of being, which is resolved into a dyadic structure unsusceptible of a dianoetic or arithmetical account. This problem leads beyond counting to dialectic as the required means of showing that both true and false logos, and hence non-being itself, are within being. (shrink)

Plato’s doctrine of the ideal state is the first form of political philosophy in the written history for European thought. The influence of Plato on the formation of political philosophy cannot be overestimated, since its further development in one way or another was based on the discourse and methodology that was set by his dialogues. This study aims to identify common discourses and dialectical foundations of the most influential modern schools of political philosophy converging in the ideas of Plato. Also, (...) the study is aimed at identifying the main forms in which the philosophical ideas of Plato function in modern political philosophy in an explicit and implicit way. The contribution of the research and its novelty lies in the disclosure of the implicitly immanent features that connect political philosophy with the ideas of Plato as its primary source. (shrink)

Being can no longer be thought, for Plato, in accordance with Parmenides’ either/or; rather, it is both/and, both present in and absent from things, which is how they can come-to-presence and go-out-into-absence. But as the Parmenides demonstrates, Greek grammar hints at a fundamental ontological truth: the expression, “one one,” ἓν ἕν, shows that being can be implied, neither present nor absent—for being is an implication. But then participating must be rethought in terms of implying: being is implied in everything that (...) is and is one, which is how it is present in beings and absent therefrom. But this understanding of participation—as Aristotle insists—is contradictory. Luckily, there is another way: implication qua belonging—being no longer participates-in, but belongs-to things, which is how it is one with them, distinct but inseparable. But this too, betrays implication, fails to grasp being’s way of being, and the meaning of being qua implied, and so cannot illuminate how being and beings are and are one—for as the suspension of presence and/or absence, implying is irreducible to participating or belonging. Rather, if being is implied, it is because implication is suspension, which is why it is so suspenseful. (shrink)

By comparing the role of harmony in Eryximachus’ discourse with other Platonic passages, especially from the Timaeus, this article aims to provide textual evidence concerning Plato’s conception of cosmological medicine as “harmonic techne”. The comparison with other dialogues will enable us to demonstrate how Eryximachus’ thesis is consistent with Plato’s cosmology — a cosmology which cannot be reduced to a physical conception of reality but represents the expression of a dialectical, and erotic cosmos, characterized by the agreement of parts. Arguably, (...) Eryximachus’ discourse is expression of the Platonic tendency to translate onto the philosophical plane the implications of a model peri physeos. Harmonic techne is thus always linked to the theme of moral responsibility: the philosopher is also doctor, musician and demiurges in his harmonizing activity. The speech of Eryximachus can be approached as a Platonic step which is fundamental for establishing the need for a “medicine” to cure disorder, with a view to obtaining a cosmos ordered according to the harmonic principle.

A study of the methods, approaches, prayers, etc to realize the 'unity experience' with THE ONE REAL SELF (Vedanta, Hinduism, ) God (Judaism), Gottheit (Christianity), Buddha mind (Buddhism), The Beloved (Sufism, Islam) of a number of mystics from several religious traditions. I wrote about this in a number of books and articles, for example about methods, techniques, practices and methodology here: as well as exploring and illustrating the subject-matter of philosophizing here: Explorations, questions and searches not put down on (...) paper are probably more important than the ones mentioned above. These were occurrences for almost as long as I can remember. They took many forms, endless questions about everything under the sun, unsatisfied with unexplained socio-cultural institutions, communities, social relationships, social roles, behaviour, values, norms and much more – I had to question them rather than merely submit to them or act in accordance with them. Although I expressed these questions and queries about the status quo in many areas such as sport, art, social sciences, endless reading and marginal groups and relationships I realized that they form part of the philosophical discourse. Not the discourse that has become the expression of the professionalization of philosophy the last few hundred years, but of the not-institutionalized practice of original thinking, of creative philosophical thinking. As examples of the latter, Socrates, of course, the pre-Socratics, Plato, Leibniz, Spinoza, Kant, Hegel, Plotinus, writers on Mysticism such as Meister Eckhart, van Ruysbroeck, John of the Cross, Teresa of Avila, Nietzsche, Kierkegaard, from Advaita, Zen and other Buddhist schools, Wittgenstein, Hume, German Idealists, Rumi, novelists and poets, Paul Klee and other visual artists and many names who form part of the seeking for the unity-experience as explored in History of Mysticism (those who seek the unity experience, to become ONE with THE ONE, Godhead, the one real Self, Buddha mind, Sophos, etc). History of Mysticism *was first published by Atma Books in 1987, now and is a unique compendium of the lives and teachings of the world's best known mystics. They are presented in chronological order, and include representatives of every religious tradition, revealing the broad universality of genuine religious experience. expanded and revised Thirtieth Anniversary edition is available as a free downloadable PDF document on this website at my Downloads page.

Given its brevity, Plato's Meno covers an astonishingly wide array of topics: politics, education, virtue, definition, philosophical method, mathematics, the nature and acquisition of knowledge and immortality. Its treatment of these, though profound, is tantalisingly short, leaving the reader with many unresolved questions. This book confronts the dialogue's many enigmas and attempts to solve them in a way that is both lucid and sympathetic to Plato's philosophy. Reading the dialogue as a whole, it explains how different arguments are related to (...) one another and how the interplay between characters is connected to the philosophical content of the work. In a new departure, this book's exploration focuses primarily on the content and coherence of the dialogue in its own right and not merely in the context of other dialogues, making it required reading for all students of Plato, be they from the world of classics or philosophy.

This chapter focuses on the development of Gerhard Gentzen's structural proof theory and its connections with intuitionism. The latter is important in proof theory for several reasons. First, the methods of Hilbert's old proof theory were limited to the “finitistic” ones. These methods proved to be insufficient, and they were extended by infinitistic principles that were still intuitionistically meaningful. It is a general tendency in proof theory to try to use weak principles. A second reason for the importance of intuitionism (...) for proof theory is that the proof-theoretical study of intuitionistic logic has become a prominent part of logic, with applications in computer science.

In his Republic Plato considers grasping the unity of mathematics as the ultimate goal of the mathematical studies in which the future philosopher-rulers must engage before they turn to philosophy. How the unity of mathematics is supposed to be understood is not explained, however. This book argues that Plato conceives of the unity of mathematics in terms of the mutually benefiting links between its branches, just as he conceives of the unity of the state outlined in (...) the Republic in terms of the common benefit for all citizens. Evidence for this view is provided by a discussion of his conception of astronomy as a propedeutic to philosophy, which can be best understood as hinting at a historically possible link between fourth-century-BC astronomy and solid geometry. The monograph also includes a detailed discussion of two well-known stories about Plato: not only he motivated Greek mathematicians to solve a difficult problem in solid geometry with his interpretation of a Delphic oracle given to the inhabitants of the island of Delos but he also posed the question which led to the development of the astronomical theory of homocentric spheres. It is argued that these stories are best understood as fictional episodes in Plato's life, constructed from passages in his works. (shrink)

A lively dialogue between a foreign philosopher and a powerful statesman, Plato's Laws reflects the essence of the philosopher's reasoning on political theory and practice. It also embodies his mature and more practical ideas about a utopian republic. Plato's discourse ranges from everyday issues of criminal and matrimonial law to wider considerations involving the existence of the gods, the nature of the soul, and the problem of evil. Translated by the distinguished scholar Benjamin Jowett, this edition is an authoritative choice (...) for students of philosophy, political science, and literature. (shrink)

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.

Plato's Republic, one of the great works in the history of philosophy, is presented here as it was written - as a dramatic performance exploring various perspectives on justice, truth, knowledge, and the good. Plato wrote each book of The Republic to be performed by actors playing the characters of Socrates, Glaucon, Adeimantus, Thrasymachus, and the others. When Book One was performed, he then invited his students—the brightest and best young people in Athens—to respond to each and every argument, issue, (...) and question posed by the characters. Rather than passively listening, they were lured into the process and challenged to evaluate and improve on the ideas presented in the performance. Based on their responses, Plato then wrote Book Two. The same process was repeated, and Book Three was generated. In this way all ten books evolved as part of a dynamic and creative dialectic intended to take place in the souls of each and every participant—including Plato himself. This dramatized version is an adaptation of the Benjamin Jowett translation. (shrink)

The Phaedo is acknowledged to be one of Plato's greatest masterpieces, showing him both as a philosopher and as a dramatist at the height of his powers. For its moving account of the execution of Socrates, the Phaedo ranks among the supreme literary achievements of antiquity.

This new edition is a revised version of the Clarendon Press (...) translation, and is eminently suitable for readers new to Plato, and ideal for classroom use, thanks to the provision of Stephanus page and letter numbering.

Gentzen writes in the published version of his doctoral thesis Untersuchungen über das logische Schliessen that he was able to prove the normalization theorem only for intuitionistic natural deduction, but not for classical. To cover the latter, he developed classical sequent calculus and proved a corresponding theorem, the famous cut elimination result. Its proof was organized so that a cut elimination result for an intuitionistic sequent calculus came out as a special case, namely the one in which the sequents have (...) at most one formula in the right, succedent part. Thus, there was no need for a direct proof of normalization for intuitionistic natural deduction. The only traces of such a proof in the published thesis are some convertibilities, such as when an implication introduction is followed by an implication elimination [1934–35, II.5.13]. It remained to Dag Prawitz in 1965 to work out a proof of normalization. Another, less known proof was given also in 1965 by Andres Raggio.We found in February 2005 an early handwritten version of Gentzen's thesis, with exactly the above title, but with rather different contents: Most remarkably, it contains a detailed proof of normalization for what became the standard system of natural deduction. The manuscript is located in the Paul Bernays collection at the ETH-Zurichwith the signum Hs. 974: 271. Bernays must have gotten it well before the time of his being expelled from Göttingen on the basis of the racial laws in April 1933. (shrink)

'What exactly is knowledge?' The Theaetetus is a seminal text in the philosophy of knowledge, and is acknowledged as one of Plato's finest works. Cast as a conversation between Socrates and a clever but modest student, Theaetetus, it explores one of the key issues in philosophy: what is knowledge? Though no definite answer is reached, the discussion is penetrating and wide-ranging, covering the claims of perception to be knowledge, the theory that all is in motion, and the perennially tempting idea (...) that knowledge and truth are relative to different individuals or states. The inquirers go on to explore the connection between knowledge and true judgement, and the famous threefold definition of knowledge as justified true belief. Packed with subtle arguments, the dialogue is also a work of literary genius, with an unforgettable portrait of Socrates as a midwife of wisdom. This new edition uses the acclaimed translation by John McDowell. It includes a valuable introduction that locates the work in Plato's oeuvre, and explains some of the competing interpretations of its overall meaning. The notes elucidate Plato's arguments and draw connections within the work and with other philosophical discussions.

“As one would expect from the team of Brann, Kalkavage and Salem, their edition of Plato's _Meno_ is a fine one. The translation meets their stated goal of remaining 'as faithful as possible to the Greek, while using lively, colloquial English.' Their notes are consistently helpful and will be particularly useful to those readers willing to explore the nuances of Plato's extraordinary prose. Their introduction is clear and compact, and it highlights the most philosophically important themes of the dialogue. One (...) particularly useful feature of this edition is the manner in which it displays the diagrams Socrates draws in order to illustrate his famous 'square within a square.' Instead of relegating them to the notes, it integrates them into the text of the dialogue itself. Readers are able to follow along, and 'watch' Socrates actually construct them." _—David Roochnik, Boston University_. (shrink)

Although my main goal is to provide a context for a deeper understanding of Plato's political thought, I introduce distinctions and principles that may be profitably applied to other political thinkers and represent considerations all political scholars should address, and I conclude with two critical comments on Plato's aristocracy. In proceeding, I will argue first that the inconsistency reading is inadequate because there is sufficient textual support for attributing to Plato two theses that make different, even conflicting, political prescriptions appropriate. (...) I then argue that the full consistency reading is inadequate because it obscures important and genuine differences in Plato's two accounts. In the course of these two arguments, the weak consistency reading is explained and defended through textual support. My final tasks are to add a clarification of the weak consistency reading, address a likely objection to my view, and raise two critical concerns for Plato's aristocracy. (shrink)

Gentzen writes in the published version of his doctoral thesis Untersuchungen über das logische Schliessen that he was able to prove the normalization theorem only for intuitionistic natural deduction, but not for classical. To cover the latter, he developed classical sequent calculus and proved a corresponding theorem, the famous cut elimination result. Its proof was organized so that a cut elimination result for an intuitionistic sequent calculus came out as a special case, namely the one in which the sequents have (...) at most one formula in the right, succedent part. Thus, there was no need for a direct proof of normalization for intuitionistic natural deduction. The only traces of such a proof in the published thesis are some convertibilities, such as when an implication introduction is followed by an implication elimination [1934–35, II.5.13]. It remained to Dag Prawitz in 1965 to work out a proof of normalization. Another, less known proof was given also in 1965 by Andres Raggio.We found in February 2005 an early handwritten version of Gentzen's thesis, with exactly the above title, but with rather different contents: Most remarkably, it contains a detailed proof of normalization for what became the standard system of natural deduction. The manuscript is located in the Paul Bernays collection at the ETH-Zurichwith the signum Hs. 974: 271. Bernays must have gotten it well before the time of his being expelled from Göttingen on the basis of the racial laws in April 1933. (shrink)

This volume contains new translations of two dialogues of Plato, the Protagoras and the Meno, together with explanatory notes and substantial interpretive essays. Robert C. Bartlett's translations are as literal as is compatible with sound English style and take into account important textual variations. Because the interpretive essays both sketch the general outlines of the dialogues and take up specific theoretical or philosophic difficulties, they will be of interest not only to those reading the dialogues for the first time but (...) also to those already familiar with them. The Protagoras and the Meno are linked by the attention each pays to the idea of virtue: the latter dialogue focuses on the fundamental Socratic question, "What is virtue?"; the former on the specific virtue of courage, especially in its relation to wisdom. An appendix contains a short extract from Xenophon's Anabasis of Cyrus that vividly portrays the figure of Meno. (shrink)

ABSTRACTThough the perennial problem of consciousness has outlasted the idealists, the reductivist turn in contemporary naturalistic philosophy of mind and the non-reductivist reactions to it provoke us to re-think post-Kantian idealism. Fichte's Wissenschaftslehre makes for a classical case of non-reductivist approach to mind and his critique of ‘dogmatism’ is all the more relevant in this context. This article contains four sections. The first section is an introduction that explains why post-Kantian idealism is relevant to contemporary philosophy of mind. The second (...) section pinpoints the placement issue that confronts not only current philosophers but also partially motivated Fichte's own philosophy. The third section is a short but essential remark about the normative and practical valence of ‘knowledge’ and ‘science’ in Fichte's traditional understanding of them. In the fourth section, I provide a reconstructive analysis of Fichte's understanding and critique of physicalism. Fichte's argument can be analyzed into two horns with each targeting reductivism and epiphenomenalism respectively. The final section is a brief but positive exposition on a necessary feature, namely reflexivity, of mind and the first-person perspective. Fichte's appropriation of intellectual intuition exemplifies a non-representationalist picture that connects content transparency with the active nature of mind. (shrink)

Graham Priest presents an original exploration of philosophical questions concerning the one and the many. He covers a wide range of issues in metaphysics--including unity, identity, grounding, mereology, universals, being, intentionality, and nothingness--and deploys the techniques of paraconsistent logic in order to offer a radically new treatment of unity. Priest brings together traditions of Western and Asian thought that are usually kept separate in academic philosophy: he draws on ideas from Plato, Heidegger, and Nagarjuna, among other philosophers.

Burnet's text should be emended or repunctuated at three points. At d I we should follow Moreschini and with BT omit Proclus' γε: the unanimous voice of our best manuscripts must be allowed to drown the unreliable Neoplatonist. At e 2, as I shall argue, should be excised. And at e 2–3 the clause is to be attributed to Aristoteles, as Brumbaugh advocates. This attribution gives a better and more typical question and answer sequence, although I can find no other (...) example where Aristoteles ventures sua sponte. (shrink)

This essay examines several of Plato’s philosophical texts to show how in the process of trying to differentiate rhetoric and medicine—to prove that medicine is an art or science like philosophy, and that rhetoric, in comparison, is just a knack or skill—Plato indirectly and unwittingly reveals just how similar the two practices may be. As such, this essay seeks a fuller interpretation of Plato’s attitude toward rhetoric, supplementing the work of scholars who claim the only evidence Plato gives us about (...) an ideal rhetoric is through its relationship to philosophy. This essay shows instead that Plato captures the potential of rhetoric as a true art precisely through its intricate relationship to medicine. (shrink)

These dramatized, unabridged versions of Plato's Euthyphro, Apology, Crito, and Phaedo present the trial, imprisonment, and execution of Socrates, who Phaedo said was the "wisest, best, and most righteous person I have ever known."In the Euthyphro Socrates approaches the court where he will be tried on charges of atheism and corrupting the young. On the way he meets Euthyphro, an expert in religious matters. Socrates challenges Euthyphro's claim that ethics should be based on religion.In the Apology Socrates presents his own (...) defense. He explains why he has devoted his life to challenging the most powerful and important people, a process that has generated great resentment and has led to his indictment. He insists that instead of being punished he should be rewarded for his services to his fellow citizens. Socrates fails in his attempt to avoid the death sentence, but his friend Crito has bribed the guards offers him a way to escape. In the third dialogue Crito tries to persuade Socrates that it is right to flee from the unjust sentence imposed on him. In the course of their conversations they probe the foundations of civil and moral law, and treat issues that are as relevant to our time as to theirs.The Phaedo presents Socrates' final conversation. What will become of him once he drinks the poison prescribed for his execution? Socrates and his friends examine several arguments to prove that the death of the body does not kill the soul.

'The god wanted everything to be good, marred by as little imperfection as possible.'Timaeus, one of Plato's acknowledged masterpieces, is an attempt to construct the universe and explain its contents by means of as few axioms as possible. The result is a brilliant, bizarre, and surreal cosmos - the product of the rational thinking of a creator god and his astral assistants, and of purely mechanistic causes based on the behaviour of the four elements. At times dazzlingly clear, at times (...) intriguingly opaque, this was state-of-the-art science in the middle of the fourth century BC. The world is presented as a battlefield of forces that are unified only by the will of God, who had to do the best he could with recalcitrant building materials.The unfinished companion piece, Critias, is the foundational text for the story of Atlantis. It tells how a model society became corrupt, and how a lost race of Athenians defeated the aggression of the invading Atlanteans. This new edition combines the clearest translation yet of these crucial ancient texts with an illuminating introduction and diagrams. (shrink)

This paper discusses different interpretations of probability in relation to determinism. It is argued that both objective and subjective views on probability can be compatible with deterministic as well as indeterministic situations. The possibility of a conceptual independence between probability and determinism is argued to hold on a general level. The subsequent philosophical analysis of recent advances in classical statistical mechanics (ergodic theory) is of independent interest, but also adds weight to the claim that it is possible to justify an (...) objective interpretation of probabilities in a theory having as a basis the paradigmatically deterministic theory of classical mechanics.

In Plato's Ion & Meno, Socrates questions Ion, an actor who just won a major prize, about his ability to interpret the epic poetry of Homer. As the dialogue proceeds, the nature of human creativity emerges as a mysterious process and an unsolved puzzle. A similar discussion between Socrates and Meno probes the subject of ethics. Can goodness be taught? If it can, then we should be able to find teachers capable of instructing others about what is good and bad, (...) right and wrong, or just and unjust. Socrates and Meno are unable to identify teachers of ethics, and we are left wondering how such knowledge could be acquired. The text is presented in an updated version of the Jowett translation, which helps to bring the work to life for students and non-academic audiences. (shrink)

Plato's Republic, one of the great works in the history of philosophy, is presented here as it was written - as a dramatic performance exploring various perspectives on justice, truth, knowledge, and the good. Plato wrote each book of The Republic to be performed by actors playing the characters of Socrates, Glaucon, Adeimantus, Thrasymachus, and the others. When Book One was performed, he then invited his students—the brightest and best young people in Athens—to respond to each and every argument, issue, (...) and question posed by the characters. Rather than passively listening, they were lured into the process and challenged to evaluate and improve on the ideas presented in the performance. Based on their responses, Plato then wrote Book Two. The same process was repeated, and Book Three was generated. In this way all ten books evolved as part of a dynamic and creative dialectic intended to take place in the souls of each and every participant—including Plato himself. This dramatized version is an adaptation of the Benjamin Jowett translation. (shrink)

Elementary geometry can be axiomatized constructively by taking as primitive the concepts of the apartness of a point from a line and the convergence of two lines, instead of incidence and parallelism as in the classical axiomatizations. I first give the axioms of a general plane geometry of apartness and convergence. Constructive projective geometry is obtained by adding the principle that any two distinct lines converge, and affine geometry by adding a parallel line construction, etc. Constructive axiomatization allows solutions to (...) geometric problems to be effected as computer programs. I present a formalization of the axiomatization in type theory. This formalization works directly as a computer implementation of geometry. (shrink)

In the Lysis, Socrates claims to be looking for an account of what kind of quality in another person or object stimulates friendship or love (philia). He goes through a series of proposals, refuting each in turn. In the end, he throws us back to the point from where the arguments started, declaring an aporetic outcome. What is the purpose of this apparently futile and circular inquiry? Most interpreters try to reconstruct a theory of friendship or love from the arguments (...) of this dialogue. Against such a doctrinal reading, this essay defends an “aporetic reading” of the dialogue and connects it to its protreptic function. Starting with a preliminary discussion of what defines an aporetic dialogue and what distinguishes indirect protreptic from explicit protreptic discourse, the essay then analyzes the aporetic method of the Lysis, distinguishing it from aporetic discourse in some of his earlier dialogues. Finally, it analyzes how, and for what kind of audience, the Lysisfunctions as an indirect protreptic. This includes a comparison with the protreptic use of aporetic argumentation in the Euthydemus.
