Plato, Misc

This paper aims to suggest a new arrangement of Plato’s dialogues based on a different theory of the ontological as well as epistemological development of his philosophy. In this new arrangement, which proposes essential changes in the currently agreed upon chronology of the dialogues, Parmenides must be considered as criticizing an elementary theory of Forms and not the theory of so-called middle dialogues. Dated all as later than Parmenides, the so-called middle and late dialoguesare regarded as two consecutive endeavors to (...) resolve the problems drawn out in there; an effort in the theory of knowledge through Theaetetus, Meno and Phaedo and another in ontology through the second part of Parmenides, Sophist and Republic. -/- Key Words: Plato; chronology; development; ontology; epistemology -/- Introduction There are many determinative factors regarding the chronology of the dialogues about which our informationis terribly deficient. There is no certain evidence about the date of each of the dialogues, nor any reliable information about the beginning and ending time of Plato’s writing. The most determinative issue among all chronological matters, I am inclined to insist, is the question that if did Plato use to manipulate or, as Dionysius of Halicarnassus said (1808, 406), polish, comb and curl his previously written dialogues and, if so, to what extent? That there is almost no answer to this most crucial issue shows how far deficient, indefinite and inconclusive the chronological plans can be. The fact that we do not even have enough information to decide, in case of Socratic dialogues, to what extent they are reporting or reflecting the actual dialogues of historical Socrates, and to what extent they are Plato-made stories so that even now we have a schizophrenic character between Socrates and Plato, can be good evidence for this deficiency. There are, nevertheless, somemore certain informations that can be contributive in case of the arrangement of some dialogues. a) The only external evidence provided by Aristotle that Lawswas written after Republic (Politics, II, 6) which was repeated by others . b) Few internal evidences provided by references in dialogues themselves including: i) the cross references in the Sophist 217a and Politicus 257a and 258b which indicate the prior composition of Sophist; ii) Timaeus 27 which hints to Critias as its sequel; iii) Theaetetus 183e where Socrates says he met Parmenides when he was young which has been taken as a reference to Parmenides; iv) a similar reference to the discussion of young Socrates with Parmenides this time in Sophist 217c; v) Sophist 216a refers to a previous discussion which has been thought to be referring to Theaetetus, and vi) the Timaeus 17b-19b in which Socrates tries to summarize his previous dialogue about the structure of cities, and the kind of men these cities must bring up to become the best people and so on which, among the dialogues we have now, must refer to Republic.

La dialectique, un processus qui nous conduit à la connaissance des Formes et finalement à la Forme la plus élevée du Bien, à travers la discussion, le raisonnement, les questions et l'interprétation, a préoccupé les philosophes depuis les temps anciens. Socrate pratiquait la dialectique par la méthode du dialogue oral, qu'il appelait l'art de « la naissance des âmes » (méthode aussi appelée maya, ou méthode d'Elenchus), qui pouvait conduire, selon l'intention de Socrate, à confirmer ou infirmer déclarations, ou à (...) la soi-disant « aporie » dans laquelle aucune conclusion définitive n'a été tirée. Chez Platon, la dialectique est un type de connaissance, avec un rôle ontologique et métaphysique, auquel on accède en confrontant plusieurs positions pour dépasser l'opinion (doxa), un passage du monde des apparences (ou « sensible ») à la connaissance intellectuelle (ou « intelligible ») aux premiers Principes. Il implique également l'ordonnancement des concepts en genres et espèces par la méthode de la division, et embrasse la multiplicité dans l'unité, étant utilisé pour comprendre l'ensemble du processus d'illumination, par lequel le philosophe est éduqué afin d'atteindre la connaissance du bien suprême, le Forme du bien. -/- DOI: 10.13140/RG.2.2.30743.85925 .

L'ensemble de l'œuvre de Platon est restée intacte jusqu'à ce jour, influençant de manière décisive la culture occidentale. Pour Platon, le dialogue est le seul outil capable de mettre en évidence le caractère de recherche de la philosophie, élément clé de sa pensée. Certes, l'écrit est plus précis et approfondi que le discours, mais le discours oral permet un échange de vues immédiat sur le sujet en discussion. Le principal protagoniste des dialogues est Socrate, à l'exception des derniers dialogues où (...) il se voit attribuer un rôle secondaire, disparaissant complètement dans Lois et Épinomis. Les dialogues platoniciens ont été regroupés par de nombreux commentateurs dans diverses classifications. Selon certains, un classement serait chronologique : les premiers dialogues seraient caractérisés par la forte influence de Socrate, ceux de la maturité dans lesquels il aurait développé la théorie des idées, et la dernière période dans laquelle il éprouvait le besoin de défendre son propre conception des attaques contre l'adresse de sa philosophie, réalisant une profonde autocritique de la théorie des Idées. -/- DOI: 10.13140/RG.2.2.10198.32327.

Le modèle éducatif de Platon (paidèia) différencie le niveau d'éducation selon les compétences des élèves. Ainsi, une éducation de base comprend, outre la gymnastique et le combat (l'exercice du corps), la musique (l'exercice de l'esprit), sans être imposée par la force car un homme libre doit être libre dans la conquête du savoir. Si l'élève a des compétences, il est éduqué en mathématiques pour devenir stratège, et en astronomie pour élever l'âme. Parmi ceux-ci, les meilleurs sont sélectionnés pour devenir de (...) bons leaders, étudiant la philosophie et la dialectique. Les femmes auront les mêmes droits et devoirs que les hommes. Selon les principes socratiques, pour faire justice, il faut savoir ce qui est bien, et c'est ce que le philosophe sait le mieux. Platon a détaillé ce concept en soulignant la distinction entre le philosophe (qui cherche les principes de vérité sans prétendre les posséder) et le sophiste (qui se laisse guider par l'opinion comme seul paramètre valable de la connaissance). Platon considère les philosophes comme des leaders idéaux pour deux raisons principales : parce qu'ils savent ce qui est juste et parce qu'ils ne veulent pas diriger. -/- DOI: 10.13140/RG.2.2.14844.82564.

The Stoics have often been compared to the earthborn Giants in the Battle of Gods and Giants in Plato’s Sophist, but with diverging opinions about the lessons they drew in reaction to Plato. At issue are questions about what in the Sophist the Stoics were reacting to, how the Stoics are like and unlike the Giants, the status of being for the Stoics, and the extent to which they were Platonizing with their incorporeals. With these open questions in mind, I (...) reexamine the Sophist from the Stoic perspective, finding eight distinct challenges that are likely to have been salient to the Stoics, and offer a new account of the Stoics as responding to these challenges with an innovative ontology that prises apart something from being to make room for what is not, and a sophisticated one-world metaphysics that grounds everything there is in two fundamental bodies.

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.

Meinwald, Michael Frede, Emily Fletcher, Verity Harte, Rachana Kamtekar, and Rachel Singpurwalla. -/- The first edition of the Cambridge Companion to Plato (1992), edited by Richard Kraut, shaped scholarly research and guided new students for thirty years. This new edition introduces students to fresh approaches to Platonic dialogues while advancing (...) the next generation of research. Of its seventeen chapters, nine are entirely new, written by a new generation of scholars. Six others have been thoroughly revised and updated by their original authors. The volume covers the full range of Plato's interests, including ethics, political philosophy, epistemology, metaphysics, aesthetics, religion, mathematics, and psychology. Plato's dialogues are approached as unified works and considered within their intellectual context, and the revised introduction suggests a way of reading the dialogues that attends to the differences between them while also tracing their interrelations. The result is a rich and wide-ranging volume which will be valuable for all students and scholars of Plato. (shrink)

Platonic religiosity is the first of two volumes devoted to the analysis of religiosity or religious feeling (pathos) in Plato. -/- (Back cover) Platonic Religiosity is a hermeneutical attempt to read Platonic works from the perspective of their religiosity. The aspects examined in the book are limited for the moment to the most basic, perhaps even the simplest, dimensions of religious feeling, those involving the representation of a relationship between man and divinity, Earth and Heaven, "low" and "high". Low and (...) high are spatial metaphors constitutive of our thinking. Although, in this case, they indicate the link between man and the super-sensible world, they also presuppose, at all times, the devout feeling (and the risk) of an insurmountable distance and remoteness that divides men from the numen. The need to affirm the relationship partly overcomes the presence of this feeling of distance, but never manages to neutralise it completely. -/- Religious feeling as such always oscillates between two terms: the need to establish a relationship with the divinity, and thus to guarantee its proximity to man, and the affirmation of its transcendence, namely the distance that divides us from the numen, up to the point, eventually, where the danger becomes the greatest: the denial of the god by man (atheism) or the human feeling of being abandoned by the god. The presence of these oscillations in the Platonic texts is analysed in several chapters of the book, devoted to different themes, such as the representations of reciprocity (do ut des), the images of the friendly god and the hostile god, the feeling of the threshold, prayers and invocations, verecundia and nostalgia, the feeling of dependence, the notion of prescience, assimilation to the god, the different types of ineffability, the role of atheism and incredulity, and lastly the notion of conversion, which substantiates Platonic religiosity by characterising it in the sense of a redemption-belief.

In this article I seek to come to some understanding of the interlocutors in the first book of Plato’s Republic, particularly Cephalus. A more complete view of Cephalus not only provides some interesting ways to think about Plato and the Republic, but also suggests an interesting alternative to Plato’s view of justice. The article will progress as follows: First, I discuss Plato’s allegory of the cave. I, then, critique the cave allegory by applying the same kind of reasoning that O. (...) K. Bouwsma used to criticize Descartes’ evil genius. Next, I present what I think is a fruitful way to understand Cephalus. Finally, I draw some important conclusions regarding justice and offer some interesting critiques of Plato and Platonism. (shrink)

Freiwilligkeit, personale Identität (im Sinne eines harmonisch verfassten und stabilen Selbst) und epistemische Gewissheit sind bei den meisten antiken Philosophieschulen untrennbar miteinander verbunden und garantieren im Rahmen einer als Lebenskunst verstandenen Philosophie das Glück. Im Anlehnung an Überlegungen bei Aristoteles und dem zeitgenössischen Philosophen Peter Bieri analysieren wir, wie Entscheidungen, die zum Zeitpunkt ihres Treffens als bedingt frei und selbstbestimmt wahrgenommen wurden, im Nachhinein vom Han-delnden aufgrund des damals fehlenden Wissens über die Handlungsumstände als unfrei wahrgenommen werden und zu Erfahrungen (...) der Selbstentfremdung führen können. Anknüpfend an Pamela Hieronymis Unterscheidung zwischen zwei Formen der Ausübung mentaler Freiheit zeigen wir anhand von fiktiven Fallbeispielen, wie die Protagonisten trotz epistemischer Ungewissheit zur Autorität über ihren Geist sowie zu einer funktionalen Selbstbeziehung zurückfinden können, und stellen dies in den Kontext einer zeitgenössischen Philosophie als Lebenskunst.

Dans l’œuvre de Platon, l’image du rêve semble d’abord servir à désigner l’état d’ignorance du commun des mortels qui « rêvent » leur vie. Cet usage métaphorique ne saurait correspondre parfaitement à la pensée platoni- cienne du phénomène onirique, particulièrement lorsqu’on l’envisage d’un point de vue éthique (qu’advient-il de la vertu de l’homme dans son sommeil ?), plutôt qu’épistémologique ou ontologique. Dans la République, le sommeil apparaît essentiellement comme l’endormissement d’une partie de l’âme – la rationnelle – au profit d’une (...) autre – la désirante. Platon laisse pourtant entendre que, sous certaines conditions, les visions qui s’y manifestent ne sont pas nécessairement mensongères et pourraient même, pour certaines, avoir une origine divine. Le rêve doit donc être compris non seulement comme un moment de séparation de l’âme et du corps, mais aussi de différenciation des facultés ou parties de l’âme elles-mêmes qui acquièrent là leur autonomie propre et déploient, sans se limiter l’une l’autre, leur plein pouvoir. In Plato’s works the image of a dream at first seems to serve the purpose of indicating the state of ignorance of ordinary humans who « dream » their way through life. This metaphorical usage does not reflect perfectly Plato’s thought on the phenomenon of dreams, especially when it is considered from an ethical point of view (what happens to human virtue during sleep?) rather than an epistemological or ontological one. In the Republic sleep appears to be essen- tially where a part of the soul goes asleep – namely the rational part – to the advantage of the desiring part. However, Plato implies that under certain condi- tions the visions that occur in sleep are not necessarily false and could even, in some cases, have a divine origin. Dreams must therefore be understood not merely as a moment of separation of soul and body, but also of differentiation of the faculties or parts of the soul themselves, which acquire their own autonomy in dreams and deploy their full power without limiting one another (transl. J. Dudley). (shrink)

On chercherait en vain dans l’œuvre de Platon des développements explicites sur le silence. Mais le génie littéraire de Platon lui fait une place, et la mise en scène des dialogues, comme les interactions des personnages, mettent en jeu différentes figures du silence par lesquelles se dévoilent d’autres aspects des réflexions socratico-platoniciennes sur le langage. Les silences du philosophe s’opposent, en effet, à ceux de ses interlocuteurs, autant que la pratique philosophique du dialogue aux discours sophistiques. Car le silence véritable (...) n’est pas que l’absence de voix, ni même simplement l’attente d’une parole à venir, mais, en dernière analyse, un retour à la source du logos : la pensée et l’être même.

Socrates' attitude towards falsehood is quite puzzling in the Republic. Although Socrates is clearly committed to truth, at several points he discusses the benefits of falsehood. This occurs most notably in Book 3 with the "noble lie" (414d-415c) and most disturbingly in Book 5 with the "rigged sexual lottery" (459d-460c). This raises the question: What kinds of falsehoods does Socrates think are beneficial, and what kinds of falsehoods does he think are harmful? And more broadly: What can this tell us (...) about the relationship between ethics and epistemology? The key to answering these questions lies in an obscure and paradoxical passage in Book II; at 382a-d Socrates distinguishes between "true falsehoods" and "impure lies." True falsehoods are always bad, but impure lies are sometimes beneficial. Despite Socrates' insistence that he is not saying anything deep, his distinction is far from straightforward. Nevertheless, in order to determine why some falsehoods are beneficial and why some are always harmful, we must understand what exactly true falsehoods are and how they differ from impure lies. In this paper, I argue that true falsehoods are a restricted class of false beliefs about ethics; they are false beliefs about how one should live and what one should pursue. I refer to these beliefs as "normative commitments." False normative commitments are always pernicious because they create and sustain psychological disharmony. Unlike true falsehoods, impure lies can be about anything. Nevertheless, they are only beneficial when they help produce and sustain true normative commitments. I argue that the upshot of this is that practical concerns have a kind of primacy over theoretical concerns. (shrink)

Analisi della possibile influenza esercitata dalla lettura di Platone su Freud, e in particolare della teoria del sogno come via per conoscere dei desideri precedentemnte "repressi" esposta nella "Repubblica".

The essay illustrates the figure of Demetrios Kavàkis Rhaoul, Byzantine official at the service of the last two Paleologue emperors and of the Despots of the Peloponnese, who was also George Gemistos Plethon’s friend and student. Two short works of his are here published for the first time, one on the Sun God and another on the classification of the religions professed by humanity, alongside two small inedited letters by Plethon. In the first of the two writings, Kavàkis clears the (...) reasons for his aversion towards any kind of religion or philosophy that places the divine beyond the visible world and that believes in the existence of an intelligible or, even worse, over-intelligible world. These ideas lead him to clash not only with Christianity, but also with Plato and with the ideas of his beloved teacher Plethon, who, however, seems to agree with him in a dream. In the second writing this peculiar solar religion is reaffirmed, against the religion of poets and the religions of transcendence, warning however that nature wants some respect for the religion of ancestors, whichever this might be, when it is functional to the life of the society and of the State.

This is the annotated bibliography that accompanied Volume 2 of American Association of Philosophy Teachers Studies in Pedagogy, a special issue on teaching Plato. It includes sections covering teaching several specific dialogues: Republic, Meno, Euthyphro, Apology, Crito and Lysis, as well as sections on "Socrates as Teacher" and general articles on teaching Plato.

This paper is a study about the social dimension of the philosophical education according to Aristotle. Aristotle is not a individualistic thinker but he understands the philosophical activity in the social context of the friendship.

From the second half of the 16th century the question about Platonis Aristotelisque Concordia is no more a merely doctrinal problem, but it involves a discussion about methodus and ordo, according to the importance given to them in the coeval philosophical debate. In many cases underscoring Plato’s scientific merits, not only about inventio but also about the transmission of knowledge, meant promoting Platonism as a philosophy suitable for University. In this context the need for Platonic handbooks is perceived as compelling, (...) due to the recognised didactic superiority of Aristotle’s writings. The Compendio and the Vere Conclusioni are the specific contribution of Francesco Verino secondo, who gave holiday lectures on Plato at the Florentine Studium from 1576 to 1579. The present study focuses on the platonism of Francesco Verino, covering nearly all his works, printed and manuscript, in a constant comparison with his noble predecessors Marsilio Ficino, Giovanni Pico della Mirandola and Francesco Cattani da Diacceto. In order to give light to Verino’s lectureship, particular attention is paid to glosses in his working and teaching copy of Platonis Opera. (shrink)

Plato was a Socrates’ friend and disciple, but he wasn’t the only one. No doubt, Socrates had many followers, however, the majority of their work is lost. Was there any antagonism among his followers? Who succeeded in interpreting Socrates? Who could be considered as his successor? Of course, we don’t know if these questions emerged after the death of Socrates, but the Greek doxography suggests that there was a literary rivalry. As we underlined earlier, most unfortunately, we can’t examine all (...) of them thoroughly due to the lack of their work, but we can scrutinize Xenophon’s and Aristippus’ work. All of them, Plato, Xenophon and Aristippus, presented to a certain extent their ideas concerning education. Furthermore, they have not neglected the matter of gymnastikè, but what is exactly the role of physical education in their work? Are there any similarities or any differences between them? Since, Xenophon and Aristippus (as well as Plato) seem to be in favor of gymnastikè, it is necessary to understand its role. (shrink)

El hombre actual como dios. Textos de Platón, Lactancio, Malebranche... ISBN 978 84 686 6212 1 Published by Bubok Publishing S.L., 2015.

In this article, the author examines how Diogenes of Sinope and Plato employed the analogy of the dog in order to illustrate two very different conceptions of the philosopher. Although in both cases the analogy of the dog is used to exemplify and explain certain moral or psychological characteristics of the philosopher, the author argues that the differences between Diogenes’ and Plato’s usages of the analogy are both more essential and more philosophically significant. Thus, against those scholars who claim that (...) there is a tight link between the Cynic’s and Plato’s analogy, the author demonstrates that these two versions of the paradigm should be understood independently from one another. The article is accordingly devoted to contrasting Diogenes’ and Plato’s respective usages of the analogy of the dog in order to bring out the profound rift separating their rival conceptions of the philosopher: whereas Plato’s guardian assumes the responsibility of protecting the just society and its institutions, Diogenes’ philosopher, by contrast, defends a marginal way of living that shuns institutions altogether.

Starting with the reference to “Plato’s dictum” that Freud added in the second last page of the first edition of The Interpretation of Dreams, the author explains the convergences between the conception of dreams expounded by Plato in the Republic and Freud’s fundamental insights. The analysis of bibliographic sources used by Freud, and of his interests, allow than to suppose not only that Freud omitted to acknowledge the Plato’s theoretical genealogy of “the Via Regia to the unconscious”, but also the (...) possibility that the Republic constituted a tacit source of inspiration for the composition of The Interpretations of dreams. -/- Muovendo dal richiamo al «detto di Platone» inserito nella penultima pagina della prima edizione de "L’interpretazione dei sogni" di Freud (1899), vengono preliminarmente esposte le convergenze tra la concezione del sogno di Platone esposta ne "La Repubblica" e le intuizioni poste alla base dell’edificio freudiano. Alla luce delle fonti testuali citate e utilizzate da Freud, e dei suoi interessi, viene poi avanzata l’ipotesi che egli non soltanto abbia omesso di riconoscere la genealogia teoretica platonica della «via regia che porta alla conoscenza dell’inconscio» (p. 282), ma che l’antico dialogo abbia potuto rappresentare una fonte tacita di ispirazione per la composizione de "L’interpretazione dei sogni".

This paper examines the relationship between some scholia to the IIId book of Plato’s Republic, Proclus’ commentary on it, and the so-called Chrestomathia, a work that the manuscripts attribute to the Neoplatonic philosopher himself. The conclusion is that the relationship between the three texts is highly problematic, and that we cannot think of a simple and direct derivation from one another. The author of the scholia probably made use of texts different from those that have come down to us, or (...) alternatively he has reworked his sources in a personal way. (shrink)

Each of us is a measure. The project of advocates of change in Plato’s Theaetetus as compared with sophistic thought -/- Summary -/- One of the most intriguing motives in Plato’s Theaetetus is its historical-based division of philosophy, which revolves around the concepts of rest (represented by Parmenides and his disciples) and change (represented by Protagoras, Homer, Empedocles, and Epicharmus). This unique approach gives an opportunity to reconstruct the views of marginalized trend of early Greek philosophy - so called „the (...) sophistic movement”. Paradoxically, previous research shows little interest in sophistic thought as a source of the standpoint of advocates of change („the secret doctrine”). The roots of „the secret doctrine” were investigated in the works of Heraclitus, Aristippus, and Antisthenes or those related to “neoheracliteanism”. However, researchers did not make any significant attempt to confront this concept with the contemporary research on the sophistic movement. The conviction that sophistry was primarily humanistically oriented was one of the main reasons why researches were opposed to the fact that „the secret doctrine” could represent a true expression of Protagoras’ views. This is why J. Burnet and F. M. Cornford in their seminal works assumed that “the secret doctrine” should be attributed to Plato, who simply combined a series of loose statements into one single project. In this work, we argue that the thesis which questions the parallels between the sophists’ interests and the philosophers of nature requires a significant revision. There is ample evidence to suggest that the philosophy of nature was a part of sophists’ research. This is supported by two main arguments. First, the tutors of sophists were philosophers of nature. Second, there are numerous sources that explicitly show sophists’ interest in the physical issues. These sources include anecdotal evidence about the fact that sophists wrote works On nature. There is also information confirming that they deliberated on detailed physical issues. The analogies between the concepts attributed to the advocates of change and our knowledge about sophists from other sources is very wide and contains most elements, which are included in the project of “changeable reality” presented in Theaetetus. The deliberations on the mechanism of perception, which are close to those of flux theory of perception in Theaetetus, are present in the sources referring to Gorgias of Leontinoi, the famous sophist and rhetorician. Also, the second element of “the secret doctrine” that is the metaphysics of flux matches up with what we know about the sophists’ views from other sources. On this basis, one can deduce that – contrary to the tradition which marginalized the role of sophistic considerations on the issue of being and non-being – it was one of the major subjects of sophistic research. Its main point was the criticism of the Eleatic conception of a single and unchangeable being, which also plays a key role in the doctrine of flux in Theaetetus. The epistemological theses which are presented in Theaetetus are borne out in sophistic sources. They include the definition of knowledge as perception, the „Man-measure” formula and a number of principles, which result from these foundational theses. Sophists’ empirical preferences resonate with the theses of the advocates of change in Theaetetus. Special attention that is given to the issues of differences among people, and even to cognitive differences in one person depending on the changeable states to which a person is subject, goes well together with what we know about reciprocal influence between the sophistry and medicine. The consequences of the epistemological conception present in Theaetetus have their equivalents in sophists’ works and other testimonies. An example of these consequences may be the abolition of truth and falsehood or the abolition of contradiction, which finds its expression in the thesis ouk estin antilegein. The analogies also concern reflections on the language itself. The project of the “new language” uses categories, which were developed by sophists. These include the antithesis of nomos and physis. The general intentions of this project reflect Protagoras’ ideas, at least to the extent to which they are known from the sources reporting his thoughts on language. Plato’s Theaetetus can thus be considered a veritable treasury of sophistic motifs. Even though the problem remains unsolved and one is still not able to unambiguously decide about the author of “the secret doctrine”, one can come to a certain conclusion – even if Plato synthesized various doctrines, he must have relied in his project mostly on the elements that he borrowed from sophists. Moreover, the value of reconstructing the project of the advocates of change in Theaetetus does not consist of mere enumeration of sophistic motifs. The dialogue is key to understanding the sophistic movement, whose separate doctrines – for the lack of sources and as a result of centuries-old disregard – are usually treated as rhetorical formulae that are interpreted in many ways and have no philosophical foundations. If it is really the case that the theses attributed to Protagoras in Theaetetus were actually a part or a derivative of Protagoras’ thought, or – speaking more conservatively – if they constitute a synthesis of sophistic thought done by Plato, they could represent philosophical foundations for the most important sophistic theses: the “Man-measure” formula, the ouk estin antilegein principle, the concept of language as a tool, the idea of the relativity of good and the whole practical sphere of sophists’ activity. Contrary to the views of many researchers, we are certain that the representatives of the sophistic movement did not limit themselves only to the application of practical rules, which determined the extent of their educational or rhetorical-political activity. They were capable of creating – indeed, they did create comprehensive projects that embraced the whole thematic scope subject to philosophical reflection. (shrink)

This paper deals with Plato’s theoretical views on rhetoric, its value, its conditions, and its genuine ethical-political function. My goal is to show that, even from the theoretical and/or metarhetorical point of view (Gorgias and Phaedrus), Plato would admit the practice of arguing from probabilities (eikós) and opinions, and would accept as a legitimate part of rhetoric –in order to persuade the mob– devices such as appeals to emotion. As it is well known, concrete uses of these devices can be (...) found in the dialogues. I will refer, in this vein, to some passages of Plato’s political writings, esp. Republic and Laws, and to the role of some myths in the dialogues. Nonetheless, I sustain the necessity (and the possibility) of harmonizing this view, with Plato’s strong claim that knowledge of (and commitment to) an objective truth is essential to the true rhétor.

This essay undertakes a reexamination of the notion of the receptacle/chōra in Plato's Timaeus, asking what its value may be to feminists seeking to understand the topology of the feminine in Western philosophy. As the source of cosmic motion as well as a restless figurality, labile and polyvocal, the receptacle/chōra offers a fecund zone of destabilization that allows for an immanent critique of ancient metaphysics. Engaging with Derridean, Irigarayan, and Kristevan analyses, Bianchi explores whether receptacle/chōra can exceed its reduction to (...) the maternal-feminine, and remain answerable to contemporary theoretical concerns.

A close reading of the five mathematical studies Socrates proposes for the philosopher-to-be in Republic VII, arguing that (1) each study proposes an object the thought of which turns the soul towards pure intelligibility and that (2) the sequence of studies involves both a departure from the sensible and a return to it in its intelligible structure.

This is the review of the book by W.K.C. Guthrie, Filozofowie greccy od Talesa do Arystotelesa.

The figure of the cordial host of the Academy, who invited the most gifted mathematicians and cultivated pure research, whose keen intellect was able if not to solve the particular problem then at least to show the method for its solution: this figure is quite familiar to students of Greek science. But was the Academy as such a center of scientific research, and did Plato really set for mathematicians and astronomers the problems they should study and methods they should use? (...) Our sources tell about Plato's friendship or at least acquaintance with many brilliant mathematicians of his day (Theodorus, Archytas, Theaetetus), but they were never his pupils, rather vice versa -- he learned much from them and actively used this knowledge in developing his philosophy. There is no reliable evidence that Eudoxus, Menaechmus, Dinostratus, Theudius, and others, whom many scholars unite into the group of so-called "Academic mathematicians," ever were his pupils or close associates. Our analysis of the relevant passages (Eratosthenes' Platonicus, Sosigenes ap. Simplicius, Proclus' "Catalogue of geometers", and Philodemus' "History of the Academy", etc.) shows that the very tendency of portraying Plato as the architect of science goes back to the early Academy and is born out of interpretations of his dialogues.

This is a report on the II Symposium Platonicum, which took place in Perugia, Italy, September 1-6, 1989, and on the founding of the International Plato Society, which took place in Bevagna, Province of Perugia, Umbria, Italy, September 3, 1989.

In Republic V Socrates offer three successive waves of paradox, the first being that amongst the rulers men and women will be assigned to fulfill the same social functions and the second being that amongst the rulers the traditional private family will be abolished. In her article “Philosopher Queens and Private Wives: Plato on Women and the Family” (Philosophy and Public Affairs (1977)) Susan Moller Okin argued that Plato’s argument is that the second wave of paradox implies the first. In (...) this note I rebut Okin’s arguments and show, in part based on evidence adduced by Okin herself, that for Plato it is the first wave of paradox that implies the second. (shrink)

The main idea of this allegory is the difference between people who simply experience their sensory experiences, and call that knowledge, and those who understand real knowledge by seeing the truth. The allegory actually digs into some deep philosophy, which is not surprising since it comes from Plato. Its main idea is the discussion of how humans perceive reality and if human existence has a higher truth. It explores the theme of belief versus knowledge. The Perception Plato theorizes that the (...) group of people tied up in the cave would assume that the shadows they see on the wall are reality. Plato's theory further states that the echoing sounds the prisoners hear are perceived as reality. This false reality is all that the people in the cave know. They have no true knowledge of the real world. However, they fully believe that what they see on the cave wall is reality, and even try to name the shadows they see passing by. Plato's cave allegory further proposes that one of the prisoners escapes or gains freedom from the cave. The freed prisoner moves toward the fire, which temporarily blinds him. As he gains his eyesight and moves into the real world, he gains a greater sense of reality. (shrink)

A new advanced systems theory concerning the emergent nature of the Social, Consciousness, and Life based on Mathematics and Physical Analogies is presented. This meta-theory concerns the distance between the emergent levels of these phenomena and their ultra-efficacious nature. The theory is based on the distinction between Systems and Meta-systems (organized Openscape environments). We first realize that we can understand the difference between the System and the Meta-system in terms of the relationship between a ‘Whole greater than the sum of (...) the parts’ and a ‘Whole less than the sum of its parts’, i.e., a whole full of holes (like a sponge) that provide niches for systems in the environment. Once we understand this distinction and clarify the nature of the unusual organization of the Meta-system, then it is possible to understand that there is a third possibility which is a whole exactly equal to the sum of its parts that is only supervenient like perfect numbers. In fact, there are three kinds of Special System corresponding to the perfect, amicable, and sociable aliquot numbers. These are all equal to the sum of their parts but with different degrees of differing and deferring in what Jacques Derrida calls “differance”. All other numbers are either excessive (systemic) or deficient (metasystemic) in this regard. The Special Systems are based on various mathematical analogies and some physical analogies. But the most important of the mathematical analogies are the hypercomplex algebras, which include the Complex Numbers, Quaternions, and Octonions, with the Sedenions corresponding to the Emergent Meta-system. However, other analogies are the Hopf fibrations between hyperspheres of various dimensions, nonorientable surfaces, soliton solutions, etc. These Special Systems have a long history within the tradition since they can be traced back to the imaginary cities of Plato. The Emergent Meta-system is a higher order global structure that includes the System with the three Special Systems as a cycle. An example of this from our tradition is in the Monadology of Gottfried Wilhelm von Leibniz. There is a conjunctive relationship between the System schema and the Special Systems that produce the Meta-system schema cycle. The Special Systems are a meta-model for the relationship between the emergent levels of Consciousness (Dissipative Ordering based on the theory of negative entropy of Prigogine), Living (Autopoietic Symbiotic based on the theory of Maturana and Varela), and Social (Reflexive based on the theory of John O’Malley and Barry Sandywell). These different special systems are related to the various existenitals identified by Martin Heidegger in Being and Time and various temporal reference frames identified by Richard M. Pico. We also relate the special systems to morphodynamic and teleodynamic systems of Terrence Deacon in Incomplete Nature to which we add sociodynamic systems to complete the series of Special Systems.
