With a masterful sense of the place of rhetoric in both thought and practice and an ear attuned to the clarity, natural simplicity, and charm of Plato's Greek prose, James H. Nichols Jr., offers precise yet unusually readable translations of two great Platonic dialogues on rhetoric. The Gorgias presents an intransigent argument that justice is superior to injustice: To the extent that suffering an injustice is preferable to committing an unjust act. The dialogue contains some of Plato's most (...) significant and famous discussions of major political themes, and focuses dramatically and with unrivaled intensity on Socrates as a political thinker and actor. Featuring some of Plato's most soaringly lyrical passages, the Phaedrus investigates the soul's erotic longing and its relationship to the whole cosmos, as well as inquiring into the nature of rhetoric and the problem of writing. Nichols's attention to dramatic detail brings the dialogues to life. Plato's striking variety in conversational address is carefully reproduced, as is alteration in tone and implication even in the short responses. The translations render references to the gods accurately and non-monotheistically for the first time, and include a fascinating variety of oaths and invocations. A general introduction on rhetoric from the Greeks to the present shows the problematic relation of rhetoric to philosophy and politics, states the themes that unite the two dialogues, and outlines interpretive suggestions that are then developed more fully for each dialogue. The twin dialogues reveal both the private and the political rhetoric emphatic in Plato's philosophy, yet often ignored in commentaries on it. Nichols believes that Plato's thought on rhetoric has been largely misunderstood, and he uses his translations as an opportunity to reconstruct the classical position on right relations between thought and public activity.

Plato and Xenophon: Apologies compares two key dialogues on the death of Socrates. Socrates was accused of impiety and corrupting the youth of ancient Athens and was tried, convicted, imprisoned, and executed. Both Plato and Xenophon make clear that the charges were not brought forward in the spirit of true piety, and that Socrates was a man of real virtue and beneficence. To this day, his trial and execution remain a mark upon the democracy that put him (...) to death. These dialogues underscore the limitations of democratic relativism and emphasize the nature of philosophy or the free mind. Plato’s Apology of Socrates is both poetry and an act of reformation, justifying the life of philosophy, challenging the authority of the pagan gods and heroes, and introducing Socrates as a heroic and even divine figure. In contrast, Xenophon’s Socrates is not dialectical and otherworldly, but makes a different appeal for philosophy. From Xenophon emerges the heroic tradition of Plutarch with its reflections on the virtues and vices of great historical men. Focus Philosophical Library translations are close to and are non-interpretative of the original text, with the notes and a glossary intending to provide the reader with some sense of the terms and the concepts as they were understood by Plato and Xenophon’s immediate audience.

Anscombe ends her seminal 1958 essay “Modern Moral Philosophy” with a presentation of five characters, each answering an ancient (and contemporary) question as to “whether one might ever need to commit injustice, or whether it won’t be the best thing to do?” Her fifth character is the execrated consequentialist who “shows a corrupt mind.” But who are the first four characters? Do they “show a mind”? And what precisely is the significance (if any) of her presenting those five just (...) then? In this paper, we interpret Anscombe’s essay with an eye to making sense of her character presentation. We argue that the first four characters can be seen to embody the chief negative and positive doctrines of the essay and to thereby represent and charter a pluralistic school of anti-consequentialist ethics. The upshot is something exegetically interesting yet of broader philosophical importance. (shrink)

THE THEORY OF SOCIAL JUSTICE IN THE POLIS IN PLATO'S REPUBLIC l GREGORY VLASTOS A few years ago an international committee of classical scholars decided ...

The Hipparchus features a conversation between Socrates and an un-named companion, at an unknown time and place, about gain and whether we should in any way limit our pursuit of gain. Socrates argues intransigently that we should not place any limits on our pursuit of gain, while the companion, despite being unable to counter his arguments, is equally firm in his rejection of Socrates’ moral position. The dialogue thus shows the strength of the conviction, in the souls of decent people, (...) that unrestrained pursuit of the good things is not good for you. This conviction exists prior to calculation, and the action of the dialogue thereby testifies to the existence of man’s natural conscience. (shrink)

This dissertation presents a new translation of Plato's Euthyphro that emphasizes the literary qualities of the dialogue and also clarifies controversial philosophical passages. The translation assists a holistic interpretation of the dialogue. Main features of the commentary include attention to Euthyphro's case at the start of the dialogue. Its significance is intertwined with the whole of the work, as Euthyphro's case exemplifies a dilemma already present in Athenian religious thinking. This case intensifies the need to discover a standard notion (...) of piety against which any innovation about the gods---the charge of impiety against Socrates---can be decided. I defend a causal interpretation of the Euthyphro Dilemma, which succeeds when the ancient Greek is carefully translated, and then show how this dilemma sets the stage for a definition of piety that can succeed. The dialogue's fourth definition of piety as service to the gods appears again in the Apology as the way in which Socrates describes and defends his philosophical mission. I examine the structure of this proposed definition and relate it to the comments found in the Apology. I propose that the Delphic Dictum, "Know Thyself," is the task with which humans serve the gods, and this notion best accounts for Socratic Piety. Moreover, if Socratic Piety regards the Delphic commandment, Socrates' view of piety is less innovative than might appear. Pious actions are situated within a religious context that respects the gods and also the gulf between human and divine wisdom. (shrink)

In book VI of his Parmenides commentary, Proclus surveys the previous Neoplatonic interpretations of the “hypotheses” of Plato’s Parmenides, starting with Amelius, a disciple of Plotinus. This paper analyses Amelius’ exegesis of the hypotheses. After presenting the extant evidence about his Parmenides commentary, I explore three puzzling aspects of his interpretation: 1) unlike most Neoplatonists, Amelius distinguished eight hypotheses instead of nine. I argue that he considered the last section (Prm. 165e2-166c2) to be devoid of any positive content (...) and merged it with the previous one – contrary to the modern advocates of an eight-fold divisio textus. 2) Amelius assumed that each hypothesis deals with one layer of reality, but the precise meaning of some identifications is elusive: what are the three kinds of matter matched to hypotheses 5-7? I show that these three material layers probably correspond to three entities whose existence is posited on the basis of the Timaeus: the chōra/prime matter, the level of the element-traces, and the ordered universe. 3) In at least one point, Amelius’ exegesis disrupts the descending hierarchical ordering of the subject-matters of the hypotheses (i.e. from the highest to the lowest-ranked entity), which was an undisputed governing principle of the Neoplatonic interpretations. This irregularity depends, as I argue, on a further interpretative rule: the negative quality of a hypothesis (except for the first one) is taken to indicate some sort of debasement of the corresponding entity. Since, in the second part of the Parmenides, the negative hypotheses alternate with the positive ones, this further principle clashed with the linear downward arrangement implied by the hierarchical principle. In the conclusion of the paper, I sketch how the insights gained by this analysis can shed some light on the subsequent development of the ancient Parmenides exegesis. (shrink)

The paper argues that ancient dogmatic Platonists, beginning with Antiochus, reconstructed Plato’s ethics in different ways, as a result of their different emphasis on parts of Plato’s work and often argued with each other about what Plato’s ethics actually was. This situation, it is argued, is due to the existence of different strands of ethical views found in Plato’s work itself, such as, for instance, the Protagoras and the Gorgias versus the central books of the (...) Republic and the Philebus on the question of what eudaimonia consists in. The paper argues against the thesis of Julia Annas, outlined in her Platonic Ethics Old and New, that ancient dogmatic Platonists considered the argument of the Republic as being essentially the same with that of all Platonic dialogues and that they unanimously represented Plato’s ethical position as the view that virtue is sufficient for happiness. The testimonies regarding the ethics of Platonists like Antiochus, Plutarch, Numenius, Taurus, or Atticus rather suggest a picture of variance and tension about the reconstruction of Plato’s ethics. Antiochus, Plutarch, and Taurus, for instance, are guided by the theory of the partite soul and maintain that for Plato emotions should be balanced by reason, a view they also find in Aristotle, whereas Eudorus and Atticus appear to favor the elimination of all emotions. Alcinous and, more systematically, Plotinus tend to reconcile and synthesize into a system the different views found in Plato’s dialogues, which brings them to attribute to Plato a complex ethical doctrine. This synthesis corroborates the evidence examined in the paper in support of the view that ancient Platonists recognized diverse strands of ethics in Plato and, far from being unanimous about what Plato’s ethics was, varied significantly in their reconstruction of it.

Since the early 20th century, two new disciplines emerged in the tradition of analytic philosophy: meta-ethics and political epistemology. Nevertheless, debates on such questions go back to the ancient Greeks and, in particular, to the debates between Plato and Protagoras. This article elucidates the controversy between Plato and the influential sophist Protagoras from the perspective of contemporary meta-ethics and political epistemology. It argues that the main motivation of Plato’s philosophical endeavors is to overcome Protagoras’s skeptical claims (...) that no moral facts and no moral knowledge applicable to political issues exist. The paper defends the thesis that there exists a deep disagreement between Protagoras and Plato on the existence of moral facts and moral knowledge. A deep disagreement is a disagreement that cannot be resolved through the use of reasons and arguments. Applying the foundationalist approach Robert J. Fogelin proposes in his seminal paper “The Logic of Deep Disagreements”, this article argues that the deep disagreement between Protagoras and Plato exists because their political thought is based on “underlying principles” that clash. While Plato’s political philosophy rests on his religious and theological convictions, the political thought of Protagoras is based on his skepticism, relativism, and agnosticism. (shrink)

This pathbreaking work pursues two interwoven themes. Firstly, it engages in a deconstruction of Ancient philosopher's texts--mainly from Plato, but also from Homer and Parmenides--in order to free four Greek female figures from the patriarchal discourse which for centuries had imprisoned them in a particular role. Secondly, it attempts to construct a symbolic female order, reinterpreting these figures from a new perspective. Building on the theory of sexual difference, Cavarero shows that death is the central category on which (...) the whole edifice of traditional philosophy is based. By contrast, the category of birth provides the thread with which new concepts of feminist criticism can be woven together to establish a fresh way of thinking. Cavarero develops a philosophical narrative which, by re-interpreting each of the four figures of ancient thought, uncovers several images of the female desire for self-representation. Plato himself had not forseen that one day female subjectivity would assert its autonomy, plundering and throwing into confusion the patriarchal text in order to tell another story. (shrink)

In Plato’s Sophist (245e–247e) an argument against metaphysical materialism in the “battle of gods and giants” is presented which is oft the cause of consternation, primarily because it appears the characters are unfair to the materialist position. Attempts to explain it usually resort to restructuring the argument while others rearrange the Sophist entirely to rebuild the argument in a more satisfying form. I propose a different account of the argument that does not rely on a disservice to the materialist (...) nor restructuring Plato’s argument. I contend, instead, that the argument is enthymematic in nature, allowing the definitions employed to flow out of the reasoning as originally presented. Moreover, it suggests that Plato’s idealism was so deeply ingrained that modern defenses of materialism were not even live options. (shrink)

Presents outstanding translations of the Greek philosopher's works by leading British and American scholars of the last century.

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.

Most commentators think that Plato's account of the varieties of false pleasure is disjointed and that various types of false pleasure he identifies are false in different ways. It really doesn't look that way to me: I think that the discussion is unified, and that Plato starts with less difficult cases to build up to a point about more important but less clear cases. In this paper, I do my best to show how this might work. I don't (...) think I will ever work on this again: the experience of writing this paper and dealing with frustrating refereeing practices has led me to pretty much switch to aesthetics. I'm much happier. But here are the fruits of my labor. I know there are a few details I got wrong (in particular a place or two where I should have scrutinized Frede's translation more closely), but I still think that I'm on the right track. I hope it's useful to someone. (shrink)

De Finetti's representation theorem is a special case of the ergodic decomposition of stationary probability measures. The problems of the interpretation of probabilities centred around de Finetti's theorem are extended to this more general situation. The ergodic decomposition theorem has a physical background in the ergodic theory of dynamical systems. Thereby the interpretations of probabilities in the cases of de Finetti's theorem and its generalization and in ergodic theory are systematically connected to each other.

R.E. Allen's superb new translations of four Socratic dialogues—_Ion_, _Hippias Minor_, _Laches_, and _Protagoras_—bring these classic texts to life for modern readers. Allen introduces and comments on the dialogues in an accessible way, inviting the reader to reexamine the issues continually raised in Plato's works. In his detailed commentary, Allen closely examines the major themes and central arguments of each dialogue, with particular emphasis on _Protagoras_. He clarifies each of Plato's arguments and its refutation; places the themes in (...) historical perspective; ties each theme to interpretations of rival translations; and links the philosopher's thought to trends in late modern philosophy. Topics discussed include: whether virtue is an art, whether wisdom and courage are logically equivalent, whether virtue is knowledge, and whether to know the good is to do it. Allen connects his discussion of these issues to the Benthamite tradition of hedonism and utilitarianism and to the ethical theories of Mill, Sidgwick, Moore, and Freud. (shrink)

In this book Reale presents Plato and Aristotle. At the center of Reale’s interpretation of Plato is the fulcrum of the supersensible, the metaphysical discovery that Plato presented as a result of the Second Voyage. This discovery of the supersensible is, in Reale’s view, not only the fundamental phase of ancient thought, but it also constitutes a milestone on the path of western philosophy. Reale presents Plato in three different dimensions: the theoretic, the mystical-religious, and (...) the political. Each of these components takes on meaning from the Second Voyage. In addition, Reale has shown that only in the light of the Unwritten Doctrines handed down through the indirect tradition, do these three components, and the Second Voyage itself, acquire their full meaning, and only in this way is a unitary conception of Plato’s thought achieved. The interpretation of Aristotle that Reale proposes depends on his interpretation of Plato. Aristotle read without preconceptions is not the antithesis of Plato. Reale points out that Aristotle was unique among thinkers close to Plato, in being the one who developed, at least in part, his Second Voyage. The systematic-unitary interpretation of Aristotle which Reale has previously supported converges with the new systematic-unitary interpretation of Plato. Certain doctrinal positions which are usually reserved to treatments in monographs will be explored, because only in this way can the two distinctive traits of Aristotle’s thought emerge: the way in which he tries to overcome and confirm the Socratic-Platonic positions, and the way in which he formally creates the system of philosophical knowledge.

Plato's 'Euthyphro' is important because it gives an excellent example of Socratic dialogue in operation and of the connection of that dialectic with Plato's earlier 'Theory of Forms'. This edition of the dialogue provides a translation with interspersed commentary.

Benjamin Jowett's translations of Plato have long been classics in their own right. In this volume, Professor Hayden Pelliccia has revised Jowett's renderings of five key dialogues, giving us a modern Plato faithful to both Jowett's best features and Plato's own masterly style. Gathered here are many of Plato's liveliest and richest texts. Ion takes up the question of poetry and introduces the Socratic method. Protagoras discusses poetic interpretation and shows why cross-examination is the best way (...) to get at the truth. Phaedrus takes on the nature of rhetoric, psychology, and love, as does the famous Symposium. Finally, Apology gives us Socrates' art of persuasion put to the ultimate test--defending his own life. Pelliccia's new Introduction to this volume clarifies its contents and addresses the challenges of translating Plato freshly and accurately. In its combination of accessibility and depth, Selected Dialogues of Plato is the ideal introduction to one of the key thinkers of all time. (shrink)

The structure of derivations in natural deduction is analyzed through isomorphism with a suitable sequent calculus, with twelve hidden convertibilities revealed in usual natural deduction. A general formulation of conjunction and implication elimination rules is given, analogous to disjunction elimination. Normalization through permutative conversions now applies in all cases. Derivations in normal form have all major premisses of elimination rules as assumptions. Conversion in any order terminates.Through the condition that in a cut-free derivation of the sequent Γ⇒C, no inactive weakening (...) or contraction formulas remain in Γ, a correspondence with the formal derivability relation of natural deduction is obtained: All formulas of Γ become open assumptions in natural deduction, through an inductively defined translation. Weakenings are interpreted as vacuous discharges, and contractions as multiple discharges. In the other direction, non-normal derivations translate into derivations with cuts having the cut formula principal either in both premisses or in the right premiss only. (shrink)

The paper borrows from recent work by classicists on satyr play and demonstrates significant parallels between Plato’s Republic and the structure, theme and stereotypical contents that characterize this newly studied genre of ancient Greek drama. Like satyr play, the Republic includes repeated passages where metatheatricality can reverse the meaning. The frequent occurrence of all the stereotypical elements of satyr play in Plato’s Republic also suggests to readers that they should be responding to Socrates’ narration as they would (...) to a satyr play, again reversing meaning by communicating a set of literary expectations to Plato’s readers over the heads of Socrates’ interlocutors. As is frequently the case with satyr play, the political purpose of the drama is the critique of tyrannical government. The need for a systematically ironic interpretation of the dialogue is raised.

In addition to its interest as one of Plato's most brilliant dramatic masterpieces, the Protagoras presents a vivid picture of the crisis of fifth-century Greek thought, in which traditional values and conceptions of man were subjected on the one hand to the criticism of the Sophists and on the other to the far more radical criticism of Socrates. The dialogue deals with many themes which are central to the ethical theories which Plato developed under the influence of Socrates, (...) notably the nature of human excellence, the relation of knowledge to right conduct, and the place of pleasure in the good life. This translation of the Protagoras was originally published in 1976. In this revised edition, C. C. W. Taylor has made a number of changes in the translation and commentary, and has added a new Preface and Introduction. The Bibliography has also been extended to include titles published up to 1990.

The paper proposes (1.) a non-standard interpretation of the proverbial expression “deuteros plous” by giving a fresh look to Phaedo, 99c9-d1. Then (2.) it proceeds to the philosophical problem raised in this passage according to this interpretation, that is, the problem of the “hypothesis” or the “unproved principle”. It indicates finally (3.) the kernel of truth contained in the standard Interpretation and it concludes with some remarks on the “weakness of the logoi”.

'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.
