CRATYLUS by Plato Translated by Benjamin Jowett the Project Gutenberg Ebook of Cratylus, by Plato
CRATYLUS By Plato Translated by Benjamin Jowett The Project Gutenberg EBook of Cratylus, by Plato INTRODUCTION. The Cratylus has always been a source of perplexity to the student of Plato. While in fancy and humour, and perfection of style and metaphysical originality, this dialogue may be ranked with the best of the Platonic writings, there has been an uncertainty about the motive of the piece, which interpreters have hitherto not succeeded in dispelling. We need not suppose that Plato used words in order to conceal his thoughts, or that he would have been unintelligible to an educated contemporary. In the Phaedrus and Euthydemus we also find a difficulty in determining the precise aim of the author. Plato wrote satires in the form of dialogues, and his meaning, like that of other satirical writers, has often slept in the ear of posterity. Two causes may be assigned for this obscurity: 1st, the subtlety and allusiveness of this species of composition; 2nd, the difficulty of reproducing a state of life and literature which has passed away. A satire is unmeaning unless we can place ourselves back among the persons and thoughts of the age in which it was written. Had the treatise of Antisthenes upon words, or the speculations of Cratylus, or some other Heracleitean of the fourth century B.C., on the nature of language been preserved to us; or if we had lived at the time, and been 'rich enough to attend the fifty-drachma course of Prodicus,' we should have understood Plato better, and many points which are now attributed to the extravagance of Socrates' humour would have been found, like the allusions of Aristophanes in the Clouds, to have gone home to the sophists and grammarians of the day. -
Plato's Euthyphro and Meno
Plato's Euthyphro and Meno Reading and Essays Questions Exeter College, Oxford University, HT13 Tutor: Simona Aimar E-mail: [email protected] Weekly Meetings: TBA General Information This is a syllabus for eight weeks work for the first-year course on Plato’s Meno and Euthyphro. Please email your assignments to me 24h before the tutorials. I am afraid that I will not be able to write comments on essays that are handed in later than this (unless – for exceptional reasons, e.g. illness – I have agreed to this beforehand). You are required to do at least five essays in the course of the term, plus one set of gobbets. You should each write an essay for the first tutorial. In week 7, you will write gobbets (comments on passages) instead of an essay. In any week when you do not do an essay/gobbets, you should do the reading and think about the question in advance of the tutorial, so that you are ready to discuss the essay question in the tutorial. We shall focus each week on one of the essays in the tutorial, alternating between you and the other student who will be attending the tutorials with you. If we are focusing on your essay, I’ll ask you to summarize it at the start of the tutorial. If we are focusing on someone else’s essay, you should have read her/his essay before the tutorial, and have spent some time thinking about whether you agree with it and how it might be improved. -

PLATO’S EXPLANATORY PREDICATION A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Saul Gordon Rosenthal January 2011 © 2011 Saul Gordon Rosenthal All rights reserved PLATO’S EXPLANATORY PREDICATION Saul Gordon Rosenthal, Ph. D. Cornell University 2011 One of the most classic puzzles in Plato’s metaphysics is how to interpret his apparently self-predicational language. Plato seems committed, at least in his middle dialogues, to the view that for all forms, the form of F “is F”. For instance, he seems to say that the form of largeness itself “is large”, and to generalize this claim to all forms. Commentators have struggled to find an interpretation of such claims that is consistent with Plato’s text and that attributes to Plato a view with some plausibility. One aim of this dissertation is to show that we have good reason to doubt all of the most influential interpretations offered by commentators. The views discussed include Narrow Self-Predication, the Tautologous Identity view, two Non- Tautologous Identity views, the Pauline Predication view, Broad Self-Predication, and a view distinguishing different kinds of predication. It is doubtful whether any of these interpretations correctly captures Plato’s self-predicational commitments. Another aim of the dissertation is to argue that the textual evidence most often thought to commit Plato to the Self-Predication Assumption (SP), that for all forms, the form of F is itself an F thing, is insufficient to establish such a commitment. One chapter focuses on Plato’s repeated discussion of the resemblance between form and participant. -
A Moderately Ironic Reading of Xenophon's Oeconomicus
David M. JOHNSON Ischomachus the Model Husband? A Moderately Ironic Reading of Xenophon's Oeconomicus Xenophon's Oeconomicus is usually considered a treatise on household management masquerading as a Socratic dialogue (Pomeroy). But for others the reverse is true (Strauss and the Straussians; see also Mackenzie and Nails in EMC 1985, Too's review of Pomeroy in CR 1995, and the less orthodox Straussian Stevens). How one comes down on this issue will obviously affect one's evaluation of Ischomachus' relationship with his wife, and of Xenophon as a Socratic writer. I argue that the Oeconomicus is both Socratic and economic, both didactic and ironic. Xenophon chose Ischomachus because both his virtues and his vices have much to teach Critobulus, Socrates' immediate interlocutor, and Xenophon's readers. Our Ischomachus is probably the man whose wife went on to become the Chrysilla who would marry and bear a son to her son-in-law Callias, driving her daughter to attempt suicide (Andocides 1.124-127). There may be evidence for this in Oeconomicus itself. Callias would fall for Chrysilla again when she was "an old battleaxe" (Andocides 1.127); Ischomachus promises his wife that she can maintain her status even in old age (Oec. 7.20). The scandals which would beset Chrysilla and her children may shed light on Ischomachus' otherwise odd failure to say much about children to the wife he had married in large part for the sake of children. There are other ironies. Ischomachus hardly shares Socrates' understanding of property as that one knows how to use. Critobulus, in fact, is evidently already rich enough in conventional terms: he needs another sort of help. -
Glaucon's Dilemma. the Origins of Social Order
[Working draft. Please do not circulate or cite without author’s permission] Glaucon’s Dilemma. The origins of social order. Josiah Ober Chapter 2 of The Greeks and the Rational (book-in-progress, provisional title) Draft of 2019.09.20 Word count: 17,200. Abstract: The long Greek tradition of political thought understood that cooperation among multiple individuals was an imperative for human survival. The tradition (here represented by passages from Plato’s Republic, Gorgias, and Protagoras, and from Diodorus of Sicily’s universal history) also recognized social cooperation as a problem in need of a solution in light of instrumental rationality and self-interest, strategic behavior, and the option of free riding on the cooperation of others. Ancient “anthropological” theories of the origins of human cooperation proposed solutions to the problem of cooperation by varying the assumed motivations of agents and postulating repeated interactions with communication and learning. The ways that Greek writers conceived the origins of social order as a problem of rational cooperation can be modeled as strategic games: as variants of the non-cooperative Prisoners Dilemma and cooperative Stag Hunt games and as repeated games with incomplete information and updating. In book 2 of the Republic Plato’s Glaucon offered a carefully crafted philosophical challenge, in the form of a narrative thought experiment, to Socrates’ position that justice is supremely choice-worthy, the top-ranked preference of a truly rational person. Seeking to improve the immoralist argument urged by Thrasymachus in Republic book 1 (in order to give Socrates the opportunity to refute the best form of that argument), Glaucon told a tale of Gyges and his ring of invisibility.1 In chapter 1, I suggested that Glaucon’s story illustrated a pure form of rational and self-interested behavior, through revealed preferences when the ordinary constraints of uncertainty, enforceable social conventions, and others’ strategic choices were absent. -

Title of the Thesis: EOS: An Epistemological Ontology-driven System for Knowledge Processing Author: Dipl.-Inform. Univ. Wolfgang Wohner Keywords: Knowledge Representation and Processing, Ontologies, Epistemology, Concept Theory Abstract: This thesis introduces EOS, a new approach to knowledge representation and processing that is based on Concept Theory, a unicategorical formalism we developed for defining semanti- cally enriched formal ontologies. Generally, ontologies are a means for knowledge represen- tation and reuse. They provide a shared understanding about a knowledge domain. EOS ex- tends the scope of ontologies by offering means to also formalize epistemological processes, i.e. guidelines for knowledge processing that may be employed in knowledge acquisition, generation and retrieval tasks. This general idea is molded into an EOS framework for epis- temological ontology-driven systems for knowledge processing. On this formal basis we will show how an actual EOS system can be designed, implemented and successfully put to work. -
Theory of Forms 1 Theory of Forms
Theory of Forms 1 Theory of Forms Plato's theory of Forms or theory of Ideas[1] [2] [3] asserts that non-material abstract (but substantial) forms (or ideas), and not the material world of change known to us through sensation, possess the highest and most fundamental kind of reality.[4] When used in this sense, the word form is often capitalized.[5] Plato speaks of these entities only through the characters (primarily Socrates) of his dialogues who sometimes suggest that these Forms are the only true objects of study that can provide us with genuine knowledge; thus even apart from the very controversial status of the theory, Plato's own views are much in doubt.[6] Plato spoke of Forms in formulating a possible solution to the problem of universals. Forms Terminology: the Forms and the forms The English word "form" may be used to translate two distinct concepts that concerned Plato—the outward "form" or appearance of something, and "Form" in a new, technical nature, that never ...assumes a form like that of any of the things which enter into her; ... But the forms which enter into and go out of her are the likenesses of real existences modelled after their patterns in a wonderful and inexplicable manner.... The objects that are seen, according to Plato, are not real, but literally mimic the real Forms. In the allegory of the cave expressed in Republic, the things that are ordinarily perceived in the world are characterized as shadows of the real things, which are not perceived directly. That which the observer understands when he views the world mimics the archetypes of the many types and properties (that is, of universals) of things observed. -

We provide an overview of our previous ‘knowledge repository’ now need redefining.

This has created a peculiar kind of tension between KM and SM, in which one is perceived as derpinned by the fact that the real essence of knowledge is its threatening the continued relevance of the other. Particularly, actionability, especially when it contributes to the advancement with the advances of social media and social software, KM is more of a proposed undertaking [3]. Measuring the value of such in need of delivering measurable value to corporate organizations, contributions has been one of the main issues of disagreement if it is to remain relevant in the strategic planning and positioning in Knowledge Management, which is why we devised a of organizations. In view of this, this paper presents EMSoD mechanism for measuring the KM value which our framework — Enterprise Mobility and Social Data — a conceptual social helps in delivering to corporate organizations. -

If that is your desire, I’d like to weld you together and join you into something whole, so that the two of you are made into one. Look at your love and see if this is what you desire: wouldn’t this be all that you want?’ No one, apparently, would think that mere sex is the reason each lover takes such deep joy in being with the other. The soul of each lover apparently longs for something else, but cannot say what it is. The beloved holds out the promise of something beyond itself, but that something lovers are unable to name.1 Hephaestus’ question is a pressing one. -

The objective of this paper is to give an update on the state of the discussion and to offer my own interpretation. The words 'OtKlXtOOUVTj' and 'OtKlXtoV' are typically translated as 'jus- tice' and 'just'. Thus, (1) is rendered as 'Justice is just'. The words '6CH6'tT1~' and 'ocrtoV' are typically translated as 'piety' or 'holiness' and 'pious' or 'holy'. But 'piety' and 'holiness' are not synonyms. Humans and their actions can be pious or holy, but inanimate objects can be holy, 330c4-dl 2 330d2-el 3 331a7-b3 4 331a7-b3 182 David Wolfsdorf ~lKato(jUVT\ and 'CXn6'!T\~ at Protagoras 330-1 183 but not pious.

The Phaedo by Plato
Selections from The Phaedo by Plato The Death of Scorates, David, 1787. [The Phaedo tells the story of Socrates’ final moments spent, as one would expect, in philosophical dialogue with his friends. The main subject of the dialogue is the immortality of the soul. The Phaedo is one of Plato’s middle period dialogues and, as such, reveals much of Plato’s own philosophy. In the arguments Socrates puts forth for the immortality of the soul we find a clear exposition of both Plato’s metaphysics as well as his epistemology. In the first section we find Socrates explaining to his friends why a true philosopher does not fear death. Philosophy is here described as a preparation for death.] ECHECRATES: Were you there with Socrates yourself, Phaedo, when he was executed, or 57 did you hear about it from somebody else? PHAEDO: No, I was there myself, Echecrates. ECHECRATES: Then what did the master say before he died, and how did he meet his end? I should very much like to know. None of the people in Phlius go to Athens much in these days, and it is a long time since we had any visitor from there who could give us any definite b information, except that he was executed by drinking hemlock. Nobody could tell us anything more than that. PHAEDO: Then haven't you even heard how his trial went? 58 ECHECRATES: Yes, someone told us about that, and we were surprised because there was obviously a long interval between it and the execution. How was that, Phaedo? PHAEDO: A fortunate coincidence, Echecrates.
