Republic is the central work of the western world's most famous philosopher. Essentially an inquiry into morality, Republic also contains crucial arguments and insights into many other areas of philosophy. It is also a literary masterpiece: the philosophy is presented for the most part for the ordinary reader, who is carried along by the wit and intensity of the dialogue and by Plato's unforgettable images of the human condition. This new, lucid translation by Robin Waterfield is complemented by full (...) explanatory notes and an up-to-date critical introduction. (shrink)

The edition includes a select bibliography, a synopsis of each book, a glossary of terms, a glossary and index of names, and a general index.

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.

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.

This is a commentary on selected texts of Plato concerned with poetry: the Ion and relevant sections of the Republic. It is the first commentary to present these texts together in one volume, and the first in English on Republic 2 and 3 and Ion for nearly 100 years. The introduction sets Plato's views in their Greek context and outlines their influence on later aesthetic thought. An important feature of the commentary is its exploration of the ambivalence of (...) Plato's pronouncements through an analysis of his own skill as a writer. (shrink)

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 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.

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.

This pedagogical reader of the Greek text of Plato?s Gorgias, originally published for students in Victorian England, is an immensely helpful textbook for the student of the Greek language and literature. Edited by the prominent W. H. Thompson.

In Plato's Gorgias, Gorgias of Leontini, a famous teacher of rhetoric, has come to Athens to recruit students, promising to teach them how to become leaders in politics and business. A group has gathered at Callicles' house to hear Gorgias demonstrate the power of his art. This dialogue blends comic and serious discussion of the best human life, providing a penetrating examination of ethics, the foundations of knowledge, and the nature of the good.

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)

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)

Plato's dialogues frequently treat several topics and show their connection to each other. The Phaedrus is a model of that skill because of its seamless progression from examples of speeches about the nature of love to mythical visions of human nature and destiny to the essence of beauty and, finally, to a penetrating discussion of speaking and writing. It ends with an examination of the love of wisdom as a dialectical activity in the human mind. Phaedrus lures Socrates outside (...) the walls of Athens, where he seldom goes, by promising to share a new work by his friend and mentor Lysias, a famous writer of speeches. This dialogue provides a powerful example of the dialectical writing that Plato uses to manifest ideas that are essential to human existence and to living a good life. The Phaedrus shows how oral and written forms of language relate to each other and to philosophy. It simultaneously embodies the entire process in some of the greatest poetry ever written. (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)

A fluent and accurate new translation of the dialogue that, all of Plato's works, has seemed to speak most directly to the interests of contemporary analytical philosophers. White's extensive introduction explores the dialogue's center themes, its connection with related discussions in other dialogues, and its implication for the interpretation of Plato's metaphysics.

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. It is also a seminal document for many ideas deeply ingrained in western culture, and provides one of the best introductions to Plato's thought. 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.

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)

Written by Plato as an act of homage to Socrates, these dialogues attempt to define bravery, discuss the relationship between philosophy and politics, and include a debate on poetic inspiration.

'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.

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)

"Gill's and Ryan's Parmenides is, simply, superb: the Introduction, more than a hundred pages long, is transparently clear, takes the reader meticulously through the arguments, avoids perverseness, and still manages to make sense of the dialogue as a whole; there is a fine selective bibliography; and those parts of the translation I have looked at in detail suggest that it too is very good indeed." --Christopher Rowe, _Phronesis_.

"Gorgias" addresses the temptations of success and the rewards of a moral life while "Timaeus" explains the world in terms not only of physical laws but also of metaphysical and religious principles.

Gentzen's systems of natural deduction and sequent calculus were byproducts in his program of proving the consistency of arithmetic and analysis. It is suggested that the central component in his results on logical calculi was the use of a tree form for derivations. It allows the composition of derivations and the permutation of the order of application of rules, with a full control over the structure of derivations as a result. Recently found documents shed new light on the discovery of (...) these calculi. In particular, Gentzen set up five different forms of natural calculi and gave a detailed proof of normalization for intuitionistic natural deduction. An early handwritten manuscript of his thesis shows that a direct translation from natural deduction to the axiomatic logic of Hilbert and Ackermann was, in addition to the influence of Paul Hertz, the second component in the discovery of sequent calculus. A system intermediate between the sequent calculus LI and axiomatic logic, denoted LIG in unpublished sources, is implicit in Gentzen's published thesis of 1934—35. The calculus has half rules, half “groundsequents,” and does not allow full cut elimination. Nevertheless, a translation from LI to LIG in the published thesis gives a subformula property for a complete class of derivations in LIG. After the thesis, Gentzen continued to work on variants of sequent calculi for ten more years, in the hope to find a consistency proof for arithmetic within an intuitionistic calculus. (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)

This chapter presents an excerpt from the The Republic with Socrates conversing with Glaucon. Socrates shows Glaucon the figure of a cave to explain how far our nature is enlightened or unenlightened. He shows prisoners in an underground den facing a wall and shackled in such a way that they cannot move, and can only see before them. Men walk behind the prisoners, they and the objects they carry cast shadows on the cave wall. Knowing nothing of the real causes (...) of the shadows, the prisoners naturally mistake these shadows for the real nature of things. Plato asks whether this is analogous to our own understanding of reality; that is, is the human condition such that our grasp of reality is only partial, catching only the slightest glimpse into the true nature of things, like the prisoners’ world of shadows?.

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 Gorgias is a vivid introduction to central problems of moral and political philosophy. In answer to an eloquent attack on morality as conspiration of the weak against the strong, Plato develops his own doctrine, insisting that the benefits of being moral always outweigh any benefits to be won from immorality.

Presents translations of five dialogues from Plato, as well as additional notes on history and mythology.

Toward the end of the astonishing period of Athenian creativity that furnished Western civilization with the greater part of its intellectual, artistic, and political wealth, Plato wrote The Republic, his discussion of the nature and meaning of justice and of the ideal state and its ruler. All subsequent European thinking about these subjects owes its character, directly or indirectly, to this most famous (and most accessible) of the Platonic dialogues. Although he describes a society that looks to some like (...) the ideal human community and to others like a totalitarian nightmare, in the course of his description Plato raises enduringly relevant questions about politics, art, education, and the general conduct of life.
