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 '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.

Plato's First Alcibiades was the recognised introduction to the dialogues of Plato in late antiquity, because it addresses the important question of the nature of the self. Only by discovering this can we understand the perspective from which we view the rest of reality. It was also considered as a necessary first step in our pursuit of happiness, for unless we know what we are we cannot know what will bring about our fulfilment - and without the fulfilment of (...) our true nature we cannot be happy. As a key to human understanding and happiness, the dialogue is as important today as it was in antiquity. Approximate Stephanus pagination accompanies the text. Added to this dialogue, in the form of additional notes and an introduction, is much of Proclus' Commentary written on the understanding that "it will be found by those who are deeply skilled in the philosophy of Plato, that each of his dialogues contains that which the universe contains." The Commentary reveals to the thoughtful student the depths of this important dialogue, its universal form, and its living heart - which is the quickening of the soul by the touch of divine vision. Three modern essays, written with the newcomer in mind, accompany the text and commentary: A Survey of the Soul and Socrates as the Symbolic Daemon of the Alcibiades by Tim Addey, and Possibilities of Self by Guy Wyndham-Jones.

"Plato's Statesman reconsiders many questions familiar to readers of the Republic: questions in political theory - such as the qualifications for the leadership of a state and the best from of constitution (politeia) - as well as questions of philosophical methodology and epistemology. Instead of the theory of Forms that is the centrepiece of the epistemology of the Republic, the emphasis here is on the dialectical practice of collection and division (diairesis), in whose service the interlocutors also deploy (...) the ancillary methods of myth and of models (paradeigmata). Plato here introduces the doctrine of due measure (to metrion) and a conception of statecraft (politikē) as an architectonic expertise that governs subordinate disciplines such as rhetoric and the military - doctrines later developed by Aristotle. Readers will find a sustained defence of the importance of expertise (technē or epistēmē) in the conduct of affairs of state, a robust (although not unqualified) defence of the rule of law, and an unsparing but nuanced critique of democratic government. The chapters in this volume provide a comprehensive and detailed philosophical engagement with the entirety of Plato's wide-ranging dialogue, with successive chapters devoted to the sections of the dialogue as it unfolds, and an introduction that places the dialogue in the context of Plato's philosophy as a whole. While not a commentary in the traditional sense, the volume engages with Plato's Statesman in its entirety" -- Publisher's description. (shrink)

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)

Plato's most magisterial dialogue, the Republic, takes up the question "what is justice," and its central image is an imaginary city constructed in speech designed to aid in this inquiry. In Book V of the Republic, Socrates tells his interlocutors that they have completed the "Male Drama," of the city in speech and that it is now time for them to take up the "Female." The "Female Drama" is Socrates name for the action of the central books of the (...) Republic: V-VII. Much has been made of what this transition in the Republic signifies for political questions. The Republic is not only concerned with politics or political justice, however. Like all of the images and arguments in the Republic, the Female Drama of the city in speech has meaning both for political and individual justice, but there has been no systematic inquiry into the central books of the Republic for their meaning for individual justice. That is the ambition of this book. On the level of moral psychology, Thomas argues that while the Male Drama of Books II-IV presents images of fully formed versions of the psychological activities that come together to define justice in a human life, the Female Drama explores the modes of potentiality and becoming necessary for those psychological activities to come into being. More specifically, Books V-VII explore the three modes of potentiality necessary for the development of justice: genesis, trophe, and paideia. (shrink)

Gentzen's “Untersuchungen” [1] gave a translation from natural deduction to sequent calculus with the property that normal derivations may translate into derivations with cuts. Prawitz in [8] gave a translation that instead produced cut-free derivations. It is shown that by writing all elimination rules in the manner of disjunction elimination, with an arbitrary consequence, an isomorphic translation between normal derivations and cut-free derivations is achieved. The standard elimination rules do not permit a full normal form, which explains the cuts in (...) Gentzen's translation. Likewise, it is shown that Prawitz' translation contains an implicit process of cut elimination. (shrink)

Plato's Sophist is a dialogue which is key to the understanding of Platonic metaphysics and dialectics: its traditional subtitle is 'On Being.' Thomas Taylor's translation was first published in 1804 as part of his Works of Plato - the first ever complete translation of Plato into English. This Students' Edition volume has extensive notes to help those coming anew to the Sophist to grasp some of the important concepts which stand behind the dialogue. Also added is an extract from (...) Proclus On Forms, Reasons and Dialectic (from his Commentary on the Parmenides); a dissertation, On Ideas, by Thomas Taylor; and two modern essays which the Trust hopes will further the understanding of the newcomer to Plato and his tradition.

Ostensibly a discussion of the nature of justice, The Republic presents Plato's vision of the ideal state, covering a wide range of topics: social, educational, psychological, moral, and philosophical. It also includes some of Plato's most important writing on the nature of reality and the theory of the "forms." Translated with an Introduction by Desmond Lee.

In the summer of 1928, Kurt Gödel (1906–1978) embarked on his logical journey that would bring him world fame in a mere three years. By early 1929, he had solved an outstanding problem in logic, namely the question of the completeness of the axioms and rules of quantificational logic. He then went on to extend the result to the axiom system of arithmetic but found, instead of completeness, his famous incompleteness theorem that got published in 1931. It belongs to the (...) most iconic achievements of 20th century science and has been instrumental in the development of theories of formal languages and algorithmic computability – two essential components in the birth of the information society. This book explores Gödel’s way from an exceptional high-school student to a firmly established young logician. Essays in Gödel’s hand from the high school show that his central philosophical and scientific convictions were formed early on, before his university studies. Particular emphasis is laid on the course that made Gödel one of the foremost logicians of all times. The scientific biography of young Gödel is followed by English translations from Gödel’s German Gabelsberger shorthand of all his early preserved notebooks on logic and related topics. (shrink)

This excellent book consists of a translation of Plato's Euthyphro, plus "interspersed comment" intended "partly as a help to the Greekless reader in finding his way, and partly as a means of embedding the discussion of the earlier theory of Forms which follows it." That subsequent discussion is a series of sections aimed at establishing "that there is an earlier theory of Forms, found in the Euthyphro and other early dialogues as an essential adjunct of Socratic dialect" (...) and that it is not the same as the theory of Forms found in the Phaedo, Republic and other middle dialogues. In the Euthyphro Socrates' question of what holiness is assumes that there is a Form of holiness, "that this Form is a universal, the same in all holy things;... that that Form may be used as a standard, by which to judge what things are holy and what are not...; that it is an essence, by which or in virtue of which holy things are holy." As essences Forms are causes--formal, not efficient. They are "causes in the sense that they are that by which things are what they are. They therefore affect the career of the world, in that if they did not exist, the world would not be what it is." They "are not identical with their instances and [are] prior to their instances" and, hence, they are not in their instances. In fact, "Forms are as 'separate' from their instances in the early dialogues as they are" in the later ones. Do they not differ, then, from these latter Forms? Yes, because "of the way in which separation is conceived." In the Phaedo and other middle dialogues separation "involves something more than... nonidentity, independence, or priority. It involves the claim that instances of Forms are deficient imitations or resemblances of Forms.... To that theory was later conjoined, as a natural corollary, the theory that sensibles and Forms differ in their degree of reality, that Forms are more real than their instances." There are, in fact, "Two Worlds, Visible and Invisible.... The objects of the Visible World... are in a perpetually changing mortal realm, never the same with respect to each other or themselves. By contrast, Forms, the reality of whose existence we render an account in questioning and answering, exist always in the same way with respect to the same things, single in nature, alone by themselves, never in any way under any circumstances admitting alteration." This contrast between the Two Worlds is not drawn in the Euthyphro and earlier writings. Hence, between them and the middle dialogues there is a development in the theory of Forms. Of course, there also is "a unity to Plato's thought; but it is not the unity of a monument. It is the unity of growth and development, the unity of life." In these splendid pages one point remains unclear: how can a Form be universal and thus distinct from its instances and yet be their formal cause? Allen leaves no doubt that this is his position: "In Plato's early dialogues Forms are not the being of that of which they are Forms. A universal, being one, cannot constitute the being of a plurality--precisely why Aristotle was led to distinguish substantial form from universal. The Euthyphro does not imply that holiness is the being of any given holy thing or action as holy; it implies only that holiness is that by which holy things are holy. It implies, to borrow another bit of Aristotelian vocabulary, that holiness is a cause." But precisely in what way is a Form "that by which" something is what it is? Plato subsequently answers by distinguishing the Form itself, its character as participated by a particular thing, and the participant : the Form is that by which some thing is what it is through the participated character which the thing has. Is this answer implied in the Euthyphro? Or in what sense is a Form distinct from particular things? In what sense a formal cause? That puzzlement, though, is minor in the context of the entire book, which is valuable not only for the interpretation Allen gives of the early and middle dialogues but also for all sorts of unexpected bonuses. These are points either newly made or brilliantly reiterated--for example, the influence of Anaxagoras on Plato re the notion of essence and in philosophical vocabulary; Aristotle's abandonment of the contrast made in the Categories between primary and secondary substance; the crucial difference between genus/species in Aristotle and in Plato (enriched/impoverished; the analogy of a Platonic definition to mapping a field; the evaluation of Aristotle's interpretation of Plato's Forms, of his report on the "unwritten doctrines," of esoteric and exoteric teachings. This last culminates in a paragraph which all students of Plato should reflect upon constantly: "It is possible to treat Plato's text, not as evidence for something else, but as itself the primary object of historical understanding. The aim of the inquiry is then to interpret a set of literary documents, not to fathom the entertained beliefs of their author. It is reasonable, of course, to assume that the documents are a reliable index to the beliefs; but the connection, after all, is contingent, and as far as interpretation is concerned, unimportant. If Plato, in his heart of hearts, had been a nominalist, an atheist, a sceptic about immortality, and a hedonist, and had yet gone on to write the dialogues which he wrote for some obscure motive now unknown, this would not change the proper interpretation of what he wrote and privately disbelieved by one iota: when a man says what he does not believe, we may still perfectly well understand what it is he has said. The question, then, of whether Plato had beliefs he did not express, or beliefs contrary to what he did express, may be left to those with skill in the arts of divination; the historian may more reasonably limit himself to the study of texts and their meaning. If inquiry is construed in this way, it is self-referentially inconsistent to prefer the testimony of Aristotle to the evidence of Plato's text in the interpretation of Plato."--L. S. (shrink)

Our current culture is dominated by the ideology of creativity. One is supposed to create the new and not to care about the things as they are. This ideology legitimises the domination of the "creative class" over the rest of the population that is predominantly occupied by forms of care - medical care, child care, agriculture, industrial maintenance and so on. We have a responsibility to care for our own bodies, but here again our culture tends to thematize the (...) bodies of desire and to ignore the bodies of care - ill bodies in need of self-care and social care. But the discussion of care has a long philosophical tradition. The book retraces some episodes of this tradition - beginning with Plato and ending with Alexander Bogdanov through Hegel, Heidegger, Bataille and many others. The central question discussed is: who should be the subject of care? Should I care for myself or trust the others, the system, the institutions? Here, the concept of the self-care becomes a revolutionary principle that confronts the individual with the dominating mechanisms of control. (shrink)

Recently discovered documents have shown how Gentzen had arrived at the final form of natural deduction, namely by trying out a great number of alternative formulations. What led him to natural deduction in the first place, other than the general idea of studying “mathematical inference as it appears in practice,” is not indicated anywhere in his publications or preserved manuscripts. It is suggested that formal work in axiomatic logic lies behind the birth of Gentzen’s natural deduction, rather than any single (...) decisive influence in the work of others. Various axiomatizations are explored in turn, from the classical axioms of Hilbert and Ackermann to the intuitionistic axiomatization of Heyting. (shrink)

A way is found to add axioms to sequent calculi that maintains the eliminability of cut, through the representation of axioms as rules of inference of a suitable form. By this method, the structural analysis of proofs is extended from pure logic to free-variable theories, covering all classical theories, and a wide class of constructive theories. All results are proved for systems in which also the rules of weakening and contraction can be eliminated. Applications include a system of predicate logic (...) with equality in which also cuts on the equality axioms are eliminated. (shrink)

No part ot Plato's writings has been more debated than the three similes in Books VI.-VII. of the Republic, and still there is a diversity of opinion about their meaning. I believe that most of these difficulties arise from certain assumptions about their purpose which need revision. The current view applies the Cave to the Line, as Plato seems to direct, and this application, which is itself attended by considerable difficulties, leads to an assimilation of the two figures till (...) they seem to have much the same content and purpose. Again, as this makes the lower line appear to be the phenomenal world, it is thought that the simile of the sun foreshadows the theme of the Line by hinting at a connexion between the intelligible and the sensible which is made more explicit in the Line. Thus the group of similes seem mainly intended to show the dependence of Becoming upon Being. This paper will argue that such a view depends upon the misrepresentation of the symbolism adopted by Plato, that two antithetical groups of symbols are confused with one another, and that symbols are even identified with antitypes. Owing to these misinterpretations the Form of the Good has been mistaken for a material cause; both the Line and the Cave have been thought to reveal Plato as embarrassed by a dualism between sense and intellect, and the purpose of the Cave in particular, since the error is cumulative, has been completely obscured. This paper will attempt to substitute for current accounts another interpretation which will relate the three similes closely with the political arguments of Book VI., and with the Platonic education which is set forth in close connexion with them.

The similes of the Sun, Line, and Cave in the Republic remain a reproach to Platonic scholarship because there is no agreement about them, though they are meant to illustrate. I propose to analyse the form of the argument, a clue that has never been properly weighed. The Greek theory and practice of analogia and diairesis give good evidence about the method that Plato adopted; if this usage were respected, the analogical argument would not be so loosely interpreted, and the (...) double diairesis and proportion that the Line actually is could not be mistaken for a classification.

This is a proposal for rethinking the main lines of Plato’s philosophy, including some of the conceptual tools he uses for building and maintaining it. Drawing on a new interpretive paradigm for Plato’s overall vision, the central focus is on the so-called Forms. Regarding the guiding paradigm, we propose replacing the dualism of a world of Forms separated from a world of particulars, with the monistic model of a hierarchically structured universe comprising interdependent levels of reality. Regarding the (...) tools of the trade, we distinguish between three constructs that have come, one and all, and largely indiscriminately, to be regarded as Forms: Ideal Forms, Conceptual Forms, and Relational Forms. This recalibration of what we know of Plato’s outlook, tools, and methods, together with a realignment of these with his general aims, will also help restore the philosopher’s emphasis on that which is good, a perspective often blurred in the structure of two worlds.

Much of the debate about Aristotle’s criticisms of Plato has focused on the separability of the Forms. Here the dispute has to do with the ontological status of the Forms, in particular Plato’s claim for their ontological priority in relation to perceptible objects. Aristotle, however, also disputes the explanatory and causal roles that Plato claims for the Forms. This second criticism is independent of the first; even if the problem of the ontological status of the Forms (...) were resolved to Aristotle’s satisfaction, this second criticism would still stand. The problem here is not that there is no room for Aristotle’s four causes in Plato’s ontology; on the contrary, antecedents for all four can be found in Plato’s works. The problem, instead, is that Plato’s Forms fail to meet the general requirements that Aristotle sets out for the material, efficient, formal, and final causes of perceptible objects. Hence, even if the Forms were immanent in perceptible objects, they would still explain nothing about them. (shrink)

Do the later Platonic dialogues abandon the earlier doctrine of forms? If not, do the forms, as the objects or contents of thought, have any relation to experienced things? Schipper, in this lucid and scholarly study of the Parmenides, Theaetetus, Sophist, Philebus, and Timaeus, maintains that Plato continues to assume the essentials of the earlier doctrine of forms, and that while he offers no complete and explicit answer to the second question, the later dialogues do provide clues (...) which are consistent with each other. In formulating this answer, Schipper suggests that sensible things can be considered in two aspects: as immediately sensed and as known by means of the forms; the two aspects are united by the perceiving and knowing mind. However, this seems to be merely a restatement of the problem. Her other, more provocative suggestion is that forms are not discovered by an intellectual perception, but are assumed or posited as demanded by logos or argument in order to explain and define experienced things. Thus the interrelated forms can apply to things without being immanent in them. Although the treatment of the dialogues is careful, the book is primarily a spiritless exegesis of the text, together with an account of what other scholars have said. It is bereft of an index.—S. A.

There is a mystery at the heart of Plato's Parmenides. In the first part, Parmenides criticizes what is widely regarded as Plato's mature theory of Forms, and in the second, he promises to explain how the Forms can be saved from these criticisms. Ever since the dialogue was written, scholars have struggled to determine how the two parts of the work fit together. Did Plato mean us to abandon, keep or modify the theory of Forms, (...) on the strength of Parmenides' criticisms? Samuel Rickless offers something that has never been done before: a careful reconstruction of every argument in the dialogue. He concludes that Plato's main aim was to argue that the theory of Forms should be modified by allowing that forms can have contrary properties. To grasp this is to solve the mystery of the Parmenides and understand its crucial role in Plato's philosophical development. (shrink)

Plato had a great deal to say about the nature and function of the soul, much of it inspired by Socrates’ death by hemlock. According to Plato, the body and soul are two separate entities. The soul, Aristotle hypothesized, is a sort of non‐corporeal nervous system that directs sensory perception, movement, and thought, a great blob of form that animates a matter, entirely useless without a vessel to fill. In direct opposition to Plato and Socrates, Aristotle believed the physical and (...) metaphysical comprised an integrated system, and, therefore, the soul could not exist separate from a body. Medieval theologian, and later saint, Thomas Aquinas, really, really tried to tint the stained‐glass windows rose by combining the Platonic and Aristotelian philosophies on the nature of our spiritual guts. Thomas leaned much more heavily on Aristotle than he did on Plato when formulating his own theory of post‐demise, body–soul logistics. (shrink)

We discuss the one–many problem as it appears in the Philebus and find that it is not restricted to the usually understood problem about the identity of universals across particulars that instantiate them (the Hylomorphic Dispersal Problem). In fact some of the most interesting aspects of the problem occur purely with respect to the relationship between Forms. We argue that contemporary metaphysicians may draw from the Philebus at least three different one–many relationships between universals themselves: instantiation, subkind and part, (...) and thereby construct three new ‘problems of the one and the many’ (an Eidetic Dispersal Problem, a Genus–Species Problem, and an Eidetic Combination Problem), which are as problematic as the version generally discussed. We then argue that this taxonomy sheds new and interesting light on certain discussions of higher-order universals in recent Australian analytic philosophy. (shrink)

I myself became interested in textual work when I began checking the logical rigor of Plato’s Parmenides hypotheses. To my great surprise, the proof patterns were not simply valid, but as woodenly uniform and rigorous as Euclid’s Elements. Such rigor was exactly what a Neo-Platonist like Proclus would have expected, admired, and possibly imposed; it is not paralleled anywhere else in Plato. At that time, it was believed that the three primary manuscripts containing this dialogue—Oxford B, Venice T, and Vienna (...) W—came from a common archetype of a date as late as the fifth century, and that the only other records of the text of any extent—the lemmata in Proclus’ Commentary and the quoted passages in Damascius’ Problems—were, or at least could be, equally late. Only some evidence that the text as the ninth century manuscripts have it had been in this rigid form before the fifth century could finally settle the question of whether it was Plato’s own or that plus stringent re-styling. I thought that if there were traces of independent descent from some earlier archetype or archetypes, a dragnet technique applied to a collection of all the reported variant readings ought to catch them.

Despite the fact that the theory of Forms is regarded as the hallmark of Plato’s philosophy, it has remained remarkably elusive, because it is more hinted at than explained in his dialogues. Given the uncertainty concerning the nature and extension of the Forms, this article makes no pretense to coming up with solutions to all problems that have occupied scholars since antiquity. It aims to elucidate only two aspects of that theory: the indication in certain dialogues that the (...) Forms are what in modern parlance are called functions or purposes, and the indication in other dialogues that such functions rely on harmonious structures. (shrink)

Crombie's second volume deals with Plato's epistemology, cosmology and theory of forms. The author attempts to fit Plato "more into the company of Aristotle, Hume, Kant or Russell." He distinguishes Plato the poet from Plato the philosopher, and suggests that it is the poetic aspect of Plato's writings which lend credence to the mystical Plato of Plotinus. The analysis is detailed, sometimes tedious, but also at times quite ingenious.--P. S.

This article contends that Socratic wisdom (sophia) in Plato's Apology should be understood in relation to moderation (sophrosune), not knowledge (episteme). This stance is exemplified in an interpretation of Socrates' disavowal of knowledge. The god calls Socrates wise. Socrates holds both that he is wise in nothing great or small and that the god does not lie. These apparently inconsistent claims are resolved in an interpretation of elenchus. This interpretion says that Socrates is wise insofar as he does not (...) believe himself to know what he does not know. Whether one knows is demonstrated through elenchus, which moderates between knowledge claims. Thus, elenchus is productive of a kind of wisdom even if it does not produce knowledge. This claim, if true, forms a suitable basis for Socrates' defense of himself. That it does so serves as further evidence for the interpretation of sophia as sophrosune. (shrink)

Miller begins by contrasting two ways of regarding Plato’s Statesman. According to "the standard view," this late work is more a treatise than a dialogue. Here Plato’s doctrinal intent clearly overwhelmed his flair for dramatic invention. His positive teaching is presented by a stranger; Socrates the questioner is given a minor role. According to Miller, on the other hand, the Statesman is no less than any other Platonic dialogue a unity whose form and content, dramatic situation and argument, communicative function (...) and "philosophic substance," are internally related. Furthermore, the doctrine it presents is adequately understood only if one regards it both as a mean between truth and ignorance about what is in question and as a means to the truth still in question. The dialogue’s "surface" and "subsurface" content, too, are internally related. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Measurement, Pleasure, and Practical Science in Plato's Protagoras HENRY S. RICHARDSON 1. INTRODUCTION TOWARDS THE END OF THE PROTAGORAS Socrates suggests that the "salvation of our life" depends upon applying to pleasures and pains a science of measurement (metr$tik~techn~).Whether Plato intended to portray Socrates as putting forward sincerely the form of hedonism that makes these pleasures and pains relevant has been the subject of a detailed and probably (...) interminable debate, to which this paper will not directly contribute. By contrast, it seems to be supposed by almost all who have written on the topic that this hedonism, whoever is espousing it, puts forward pleasure as a single, homogeneous yardstick of value to serve as the basis of a supremely simple standard of choice. This standard simply directs one to seek the maximal amount of pleasure. The underlying supposition is that the hedonism put forward in the Protagorasallows one to define a maximum because all goods are commensurable. But, as I shall emphasize in the sequel, hedonism does not imply commensurability, nor does commensurability imply hedonism. The interpretive thesis of this essay is that the common presumption that the dialogue's hedonism carries commensurability with it has impeded our ability to understand the Protagor~'s relation to the other dialogues, and has distorted the fundamental purpose of Socrates's practical science. These matters are of more than textual interest. My reasons for trying to remain neutral as to the longstanding debate about attributing the dialogue's hedonism are not limited to wanting to avoid quagmires and remove confusions that have resulted from unwarranted interpretive assumptions. To many, the Protagorasis of tremendous importance as an early articulation of a calculative ideal for ethical or practical decisionmaking, whether or not Plato or Socrates was committed to that ideal. Looking [7] 8 JOURNAL OF THE HISTORY OF PHILOSOPHY 28:1 JANUARY x99 o back at the Protagorasfrom our twentieth-century perspective encourages the expectation that we might find there some argument for the crucial features of such a calculative ideal, as we have come to understand it. One such feature, prominent especially in the classical utilitarians, is that of the commensurability of goods, which in turn allows the precise definition of a maximizing rule.

In lieu of an abstract, here is a brief excerpt of the content:Measurement, Pleasure, and Practical Science in Plato's Protagoras HENRY S. RICHARDSON 1. INTRODUCTION TOWARDS THE END OF THE PROTAGORAS Socrates suggests that the "salvation of our life" depends upon applying to pleasures and pains a science of measurement (metr$tik~techn~).Whether Plato intended to portray Socrates as putting forward sincerely the form of hedonism that makes these pleasures and pains relevant has been the subject of a detailed and probably (...) interminable debate, to which this paper will not directly contribute. By contrast, it seems to be supposed by almost all who have written on the topic that this hedonism, whoever is espousing it, puts forward pleasure as a single, homogeneous yardstick of value to serve as the basis of a supremely simple standard of choice. This standard simply directs one to seek the maximal amount of pleasure. The underlying supposition is that the hedonism put forward in the Protagorasallows one to define a maximum because all goods are commensurable. But, as I shall emphasize in the sequel, hedonism does not imply commensurability, nor does commensurability imply hedonism. The interpretive thesis of this essay is that the common presumption that the dialogue's hedonism carries commensurability with it has impeded our ability to understand the Protagor~'s relation to the other dialogues, and has distorted the fundamental purpose of Socrates's practical science. These matters are of more than textual interest. My reasons for trying to remain neutral as to the longstanding debate about attributing the dialogue's hedonism are not limited to wanting to avoid quagmires and remove confusions that have resulted from unwarranted interpretive assumptions. To many, the Protagorasis of tremendous importance as an early articulation of a calculative ideal for ethical or practical decisionmaking, whether or not Plato or Socrates was committed to that ideal. Looking [7] 8 JOURNAL OF THE HISTORY OF PHILOSOPHY 28:1 JANUARY x99 o back at the Protagorasfrom our twentieth-century perspective encourages the expectation that we might find there some argument for the crucial features of such a calculative ideal, as we have come to understand it. One such feature, prominent especially in the classical utilitarians, is that of the commensurability of goods, which in turn allows the precise definition of a maximizing rule. If the Protagoraspresented a calculative conception involving commensurability, then we might expect to find in the dialogue some argumentfor the rational necessity of commensurability. My claim will be that since there is no compelling evidence that the idea of commensurability is found in the dialogue, there is'hardly likely to be an argument for it there. In fact, it is of philosophical interest to see how far the arguments against weakness of will and for the unity of virtue (whoever is making them) can proceed without relying upon commensurability; This way of putting the philosophical points at issue here underlines the relative modesty of what I am claiming about commensurability.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.1 (2001) 166-169 [Access article in PDF] Book Review Cross-Examining Socrates: A Defense of the Interlocutors in Plato's Early Dialogues Cross-Examining Socrates: A Defense of the Interlocutors in Plato's Early Dialogues, by John Beversluis; xii & 416 pp. Cambridge: Cambridge University Press, 2000, $69.95. This book is more than a cross-examination of Socrates: it is a carefully wrought indictment. Beversluis, unlike Socrates' historical adversaries (...) Anytus and Meletus, brings philosophically serious charges against Socrates by offering a rigorous defense of the interlocutors in Plato's early dialogues, the so-called Socratic dialogues. In so doing, he charts new territory in the vast area of recent analytic scholarship on Plato.According to traditional readings, Socrates deploys his elenchus to defeat his interlocutors, leaving them "either to retreat in anger or to submit to his power." Allegedly, Plato, guided by his Socratic intellectualism, draws them as distinctive, complex characters, though intellectually and thus ethically flawed. Beversluis argues against this standard view, providing sympathetic reassessment of Socrates' interlocutors. Although some previous scholars have defended some of the interlocutors, Beversluis widens the scope of the argument, leveling a scathing attack on Socratic intellectualism and its correlative method of moral education.He deals not only with Socrates' interlocutors and their logical defeats, but also with the idea of an interlocutor, and in so doing casts light on the philosophical dialogue as a genre. This emerges in the first and perhaps most original chapter, entitled "The Socratic Interlocutor," which may be of value to readers interested in philosophical writing or the philosophy of literature more generally. Here he illuminates Plato's use of the interlocutor, in part, by contrasting it with that of other philosophers who wrote in dialogue form, such as Augustine, Anselm, Hume, and Berkeley. The Socratic interlocutors are not, he says, "embodiments of error." Socrates, unlike the protagonists drawn by these other authors, does not subject them to his scrutiny in order to make them accept his beliefs, but rather to reject theirs. Beversluis claims that Plato's portrayal expresses his Socratic belief in the good life as one of bewilderment and uncertainty, a view, Beversluis rightly says, Plato will come to repudiate in his middle dialogues. Beversluis is clearly aware of the disparity between the [End Page 166] discomfort Socrates visits on his interlocutors and that which he is willing to endure himself.While many interpreters forgive Socrates' lapses of logic, Beversluis is unsparing. There is no reason, he thinks, to judge Socrates' arguments by any other criterion than their logical merits, and he therefore rejects the idea that Socrates' most fallacious arguments are valuable for psychological illumination. He also rejects Vlastos's view that only those of Socrates' arguments that are offered "seriously" should be criticized seriously. If they appear to be logical arguments, Beversluis contends, they must be assessed on their logical merits, not their rhetorical or therapeutic virtues. Some might find this approach rather arid until they see that Beversluis is warning the reader not to be dazzled by Socrates as the interlocutors are.It is widely believed that the aim of Socratic elenchus is to uncover the structure of a person's beliefs and to show that it is either internally inconsistent or at best unreflectively constructed. Beversluis's account, however, portrays Socrates as a Svengali who makes people assent to claims they would not otherwise accept. If this is right, Socrates is not actually elucidating the interlocutor's real beliefs. Beversluis challenges the notion of sincere assent, both as an interpretative guide to the early dialogues and as an epistemic concept. He points out that sincere belief is not simply an occurrent interior state accompanying, and indicated by, a verbal act of assent; rather, it emerges from the totality of a person's lived character, from the relation between word and act.Some readers will object to his axiom that a character in a literary work, and thus in a Platonic dialogue, has a life subject to scrutiny outside of the literary work.

The present study aims at giving factual support to the thesis that the Parmenides is serious in intention, rigorous in logical demonstration, and stylistically meticulous in its original composition. While this consideration may be tedious, still it is useful. Against a past history which has claimed to find the tone hilarious, the logic fallacious, the work inauthentic, the text in need of bracketing by divination, the whole incoherent— against these eccentricities a certain firm sobriety seems called for. I hope that (...) my conclusions find support and persist through fluctuations of philosophic and philological styles.The main difficulty with my thesis is that the text as we now have it (in Burnet's and Dies' editions) shows exceptions to every rule that might apply to style and even to logical structure. Thus it is almost but not quite uniformly true that each theorem opens with a theorem statement; that each is marked by a "questioning" response; that each deduction is valid when formalized in propositional calculus; and so on. Are the exceptions the result of careless composition; are they deliberate warnings not to take the proofs too seriously; or are they the result of errors in transmission? One way to test this is to reconstruct early versions of the text: if these show more logical rigor than the later versions the notion of a wholly valid original is supported; if they do not, the result may point toward the need for a less serious interpretation. A second thing to look for is the possibility that, here and there, parts of a coherent original text are uniquely conserved in sources other than the principal mss, B,T, and W. This assumes, of course, that the "original" text in question is the one with the best logical form, and that assumption seems justified. As a matter of fact, later copyings almost universally show deterioration, not improvement in style and logic.My textual findings are more compatible with some lines of interpretation than with others. Thus I offer some reasons for not accepting treatments of the work as a joke, mystical revelation, or abrupt metaphysical revision. The structure of the dialogue is best explained, I think, by reading it as an indirect proof that some non-Platonic interpretations of the theory of forms are unsatisfactory. In particular, these are the Megarian version (represented in the first part of the dialogue by Zeno, in the second by the First Hypothesis), and the Anaxagorean version put forward by Eudoxus (represented in the first part by Cephalus and his friends from Clazomenae, in the second by the Second Hypothesis). At the same time, the dialogue shows the need for a philosophic method other than the "hypothetical— deductive" way of dianoia; presumably this other method is the "dialectic" discussed in Republic VII. It also follows that any interpretation of the Phaedo which falls into either the Eudoxian or Megarian difficulties was not— at least at the date of the Parmenides—Plato's intended reading.Findings concerning the relations and reliability of the manuscripts of this dialogue also apply to the texts of the other Platonic dialogues which these mss contain.Further, the Parmenides is such an important work both historically and intrinsically that any insight which textual study can bring to its interpretation is a contribution to Western philosophy.

This is an analysis of the argument of the "euthyphro" that takes the dialogue form seriously. i contend that plato does "not" present socrates as defending a view incompatible with his claim in the "protagoras" that the religious ("pious") and the just are the same. the suggestion that the religious is only part of the just must be attributed to "euthyphro". i also argue that socrates does not reject the definition of the religious as what the gods love.
