Protagoras was an important Greek thinker of the fifth century BC, the most famous of the so called Sophists, though most of what we know of him and his thought comes to us mainly through the dialogues of his strenuous opponent Plato. In this book, Ugo Zilioli offers a sustained and philosophically sophisticated examination of what is, in philosophical terms, the most interesting feature of Protagoras' thought for modern readers: his role as the first Western thinker to argue (...) for relativism. Zilioli relates Protagoras' relativism with modern forms of relativism, in particular the 'robust relativism' of Joseph Margolis, gives an integrated account both of the perceptual relativism examined in Plato's Theaetetus and the ethical or social relativism presented in the first part of Plato's Protagoras and offers an integrated and positive analysis of Protagoras' thought, rather than focusing on ancient criticisms and responses to his thought. This is a deeply scholarly work which brings much argument to bear to the claim that Protagoras was and remains Plato's subtlest philosophical enemy. (shrink)

This paper aims to define the position of Protagoras on poetry, taking some crucial passages of Platonic Protagoras as texts that express the positions of the historical Protagoras. These passages, strictly incompatible with some essential theses of Plato’s thought, are the Great Speech (320c8-328d2), the intervention on the variety and variability of the good (334a3-c6) and the comment on the poem by Simonides (338e6-339d9). From these passages we can infer the position of the sophist towards poetry which (...) could be summarized in the following theses: 1. Poetry is an essential part of education. Epic poetry provides models for the education. Lyric poetry in turn helps to internalize in the souls of children the rhythm and the harmony that its verses contain. 2. However, an educated person should know how to evaluate what is right or wrong in the words of the poets. Criticism of Simonides’ poem is an example. From this perspective, the myth of Prometheus contained in the Protagoras Great Speech, which amends the versions of Hesiod and Aeschylus, can be considered as an model of poetic orthoepeia.

Reassesses the philosophical and pedagogical contributions of Protagoras Protagoras and Logos brings together in a meaningful synthesis the contributions and rhetoric of the first and most famous of the Older Sophists, Protagoras of Abdera. Most accounts of Protagoras rely on the somewhat hostile reports of Plato and Aristotle. By focusing on Protagoras's own surviving words, this study corrects many long-standing misinterpretations and presents significant facts: Protagoras was a first-rate philosophical thinker who positively influenced the (...) theories of Plato and Aristotle, and Protagoras pioneered the study of language and was the first theorist of rhetoric. In addition to illustrating valuable methods of translating and reading fifth-century B.C.E. Greek passages, the book marshals evidence for the important philological conclusion that the Greek word translated as rhetoric was a coinage by Plato in the early fourth century. -/- In this second edition, Edward Schiappa reassesses the philosophical and pedagogical contributions of Protagoras. Schiappa argues that traditional accounts of Protagoras are hampered by mistaken assumptions about the Sophists and the teaching of the art of rhetoric in the fifth century. He shows that, contrary to tradition, the so-called Older Sophists investigated and taught the skills of logos, which is closer to modern conceptions of critical reasoning than of persuasive oratory. Schiappa also offers interpretations for each of Protagoras's major surviving fragments and examines Protagoras's contributions to the theory and practice of Greek education, politics, and philosophy. In a new afterword Schiappa addresses historiographical issues that have occupied scholars in rhetorical studies over the past ten years, and throughout the study he provides references to scholarship from the last decade that has refined his views on Protagoras and other Sophists.

Taking a cue from the interpretive difficulties faced by Socrates and his interlocutors in Plato’s Theaetetus as they struggle to determine the meaning of Protagoras’ homo-mensura doctrine (HM), I argue that Protagoras, or early Protagoreans, used HM to speak on the relativity of literary criticism. For evidence I adduce an overlooked passage of the anonymous Certamen Homeri et Hesiodi, which contains an ethical formulation of HM. This formulation of HM, compatible with the portrait of Protagoras from Theaetetus, (...) explains the concern for literary interpretation latent in two sections of the Certamen. From the evidence in the Certamen, we may infer that HM was directly related to Protagorean education in civic virtue, part of which included a study of how to read and listen to texts. (shrink)

This is a collection of the late Heda Segvic's papers in ancient moral philosophy. At the time of her death at age forty-five in 2003, Segvic had already established herself as an important figure in ancient philosophy, making bold new arguments about the nature of Socratic intellectualism and the intellectual influences that shaped Aristotle's ideas. Segvic had been working for some time on a monograph on practical knowledge that would interpret Aristotle's ethical theory as a response to Protagoras. The (...) essays collected here are those on which her reputation rests, including some that were intended to form the backbone of her projected monograph. The papers range from a literary study of Homer's influence on Plato's Protagoras to analytic studies of Aristotle's metaphysics and his ideas about deliberation. Most of the papers reflect directly or indirectly Segvic's idea that both Socrates' and Aristotle's universalism and objectivism in ethics could be traced back to their opposition to Protagorean relativism. The book represents the considerable achievements of one of the most talented scholars of ancient philosophy of her generation. (shrink)

In his theory of society Protagoras, one of the most influential sophists thinkers, applies a contractarian approach, similar in many respects to those of Locke, Hobbes and Rousseau. Protagoras, unlike Aristotle or Plato, was convinced that individual perceptions and beliefs as well as those of the body political are relative, because there is no uniform ground on which things could be perceived or experienced. He offers an evolutionary account of the development of human species, arguing that society is (...) a result of a contract among its members, based on commonly shared and taught social virtues. On the other hand, Protagoras is not a nihilist: In his account there is still a possibility of an expertise within the polis, related to the good of the particular community. (shrink)

En el presente trabajo intentaremos poner en evidencia un singular enfoque sobre la pólis ateniense ofrecido por Protágoras en el diálogo platónico que lleva su nombre. Dicho enfoque, soslayado por los intérpretes, hace hincapié en la dimensión visual de la praxis política de los ciudadanos y es coherente con los posicionamientos ontológicos que emergen de los fragmentos del sofista.

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

According to a fragment of Porphyry (410 F Smith = 80 B 2 DK), containing a dialogue on the theme of plagiarism, Plato made use of the same arguments as Protagoras’ Περὶ τοῦ ὄντος against monistic thinkers, most likely the Eleatics. My paper aims to analyse Porphyry’s testimony to assess some aspects of Protagoras’ reflection on being through a comparison with parallel sources, in particular Plato’s dialogues (Theaetetus, Euthydemus, Sophist, Parmenides). I conclude that it is plausible to suppose (...) that, within the framework of a more general reflection on ὀρθοέπεια, Protagoras viewed the notion of being in Περὶ τοῦ ὄντος from a linguistic perspective.

The Protagoras is one of Plato's most entertaining dialogues. It represents Socrates at a gathering of the most celebrated and highest-earning intellectuals of the day, among them the sophist Protagoras. In flamboyant displays of both rhetoric and dialectic, Socrates and Protagoras try to out-argue one another. Their arguments range widely, from political theory to literary criticism, from education to the nature of cowardice; but in view throughout this literary and philosophical masterpiece are the questions of what part (...) knowledge plays in a successful life, and how we may acquire the knowledge that makes for success. This edition contains the first commentary in English on the Greek text for almost a hundred years. The commentary provides the assistance with linguistic, literary and philosophical detail that will enable students and scholars to savour to the full the pleasures of the Protagoras. (shrink)

In this contribution, I explore the treatment that Plato devotes to Protagoras’ relativism in the first section of the Theaetetus (151 E 1–186 E 12) where, among other things, the definition that knowledge is perception is put under scrutiny. What I aim to do is to understand the subtlety of Plato’s argument about Protagorean relativism and, at the same time, to assess its philosophical significance by revealing the inextric¬ability of ontological and epistemological aspects on which it is built (for (...) this latter aspect, I refer to contemporary discussions of relativism, mainly to Margolis’ robust relativism). I then turn to Aristotle’s treatment of Protagoras’ relativism in Metaphysics Γ, sections 5 and 6, in order to show that Plato and Aristotle surprisingly share the same view as regards the philosophical content of Protagoras’ relativism (in doing so, I take position against the standard opinion among scholars that Plato and Aristotle understand Protagoras’ relativism in different, even incompatible, ways). What I ultimately aim to demonstrate is that Protagoras’ relativism, as understood by both Plato and Aristotle, is a coherent, even attractive, philosophical position. (shrink)

In this dialogue Plato shows the pretensions of the leading sophist, Protagoras, challenged by the critical arguments of Socrates. The dialogue broadens out to consider the nature of the good life and the role of intellect and pleasure.

Este artículo se propone mostrar que el significado de aisthesis para Protágoras responde al uso y significación de la filosofía jónica, esto es, aún significa indistintamente juicio, sensación, emoción, creencia, en fin, doxa. Esto tiene una consecuencia muy relevante para la comprensión del homo mensura y la tesis que afirma: aisthesis es episteme.

Cet article examine le fragment de l’homme-mesure de Protagoras, tout d’abord en exposant les grands courants de son interprétation, ensuite et surtout en présentant les positions respectives et antagonistes de Nietzsche et Heidegger. Heidegger, contre Nietzsche, fait reposer l’homo-mensura sur un arrière-fond ontologique et platonicien, où la mesure n’est possible que depuis l’ouverture ontologique qui la précède. Cette interprétation a sa légitimité historique et philologique. Mais Nietzsche comprend le fragment comme entièrement irréductible au platonisme : Protagoras (et son (...) frère de pensée Thucydide) aurait pensé la connaissance comme l’étude de types psychologiques, non pas selon une norme épistémique stable, mais selon les variations d’intensité qui touchent toute psychè mais aussi toute communauté sociale. Je prends appui sur cette dernière intuition pour dégager ce qui me semble l’interprétation la plus riche du fragment de l’homme-mesure, à partir des remarques d’Eugène Dupréel – une interprétation sociale et normative où Protagoras est le penseur d’une praxis (la médecine, la politique…) qui, dans une situation et dans une communauté données, est capable d’améliorer les impressions subjectives du plus grand nombre.

Les penseurs qu’aujourd’hui nous appelons les sophistes ont été rassemblés en tant que groupe ou école de pensée par Platon. Platon, comme on l’a souvent dit, nous a donné (à dessein ou non) une impres­sion fausse de l’unité de ce groupe et de ses idées au ve siècle. À cette époque – et même au ive siècle – le mot « sophiste » fut une appellation souple, et les membres de ce groupe ont soutenu des idées et des posi­tions intellectuelles (...) diverses. Platon lui-même nous montre clairement, surtout dans le Protagoras, que les sophistes étaient plutôt rivaux que col­lègues dans un mouvement intellectuel cohérent. (shrink)

Plato's Theaetetus discusses and ultimately rejects Protagoras's famous claim that "man is the measure of all things." The most famous of Plato's arguments is the Self-Refutation Argument. But he offers a number of other arguments as well, including one that I call the 'Future Argument.' This argument, which appears at Theaetetus 178a−179b, is quite different from the earlier Self-Refutation Argument. I argue that it is directed mainly at a part of the Protagorean view not addressed before , namely, that (...) all beliefs concerning one's own future sensible qualities are true. This part of the view is found to be inconsistent with Protagoras's own conception of wisdom as expertise and with his own pretenses at expertise in teaching. (shrink)

PLATO: PROTAGORAS, trans, with Notes by C. C. W. Taylor. Clarendon Press: O.U.P., 1976. vii+230 pp. £7.50 cloth, £3.75 paper.

Chapter 6 offers a detailed analysis of the Protagoras conceived as the first dialogue in which Plato starts to reflect on the failure of the early dialogues and to provide definitive solutions to moral problems. Although the dialogue is labelled as aporetic, one part of it--the discussion of hedonism--is considered dialectal. How the hedonism of the Protagoras tries to be an advancement of the one of the early dialogues is examined. Then the two theories of virtues are presented: (...) the “unity thesis” and the “reciprocity thesis.” The former holds that all the virtues are the same, while the latter holds that all the virtues imply each other. Finally, it is emphasised that despite their differences, Plato does not dismiss any of the views. (shrink)

Protagoras u Sekstusa Empiryka (PH I 216) a platoński Teajtet Dzieła Sekstusa Empiryka stanowią ważne źródło doksograficzne, zawierając m. in. fragmenty i przekazy poświęcone sofistyce. Są wśród nich omówienia poglądów Protagorasa. W świetle problemów, jakie stwarza rekonstrukcja myśli tego sofisty, warto poddać badaniu źródła i perspektywę Sekstusa, zwracając szczególną uwagę na krótkie przedstawienie tez Protagorasa zawarte w Zarysach Pyrrońskich (PH I 216). Porównując omówienie Sekstusa i przedstawienie Platona w Teajtecie, dostrzec możemy podobieństwo prezentowanych poglądów. W przekazie Seksusa podobnie jak (...) w Teajtecie główny akcent położony jest na tezę homo-mensura, z którą wiąże się dwa inne podstawowe dla platońskiego dialogu wątki: zmienności rzeczy oraz "prywatności" spostrzeżeń. Mimo charakterystycznej dla sceptycyzmu modyfikacji strony pojęciowej, nadinterpretacji oraz wyrwania tez z dialogowego kontekstu przedstawienia obu wątków wykazują daleko idące paralele z Teajtetem. Bez względu na to, czy omówienie to jest dziełem samego Sekstusa, czy zaczerpnięte zostało z jakiegoś wcześniejszego źródła mającego charakter sceptycznej "ściągawki", możemy na jego podstawie wnioskować, że dialog Teajtet uważany był w późnej starożytności za wiarygodne źródło informacji na temat poglądów Protagorasa. Należy jednak podkreślić, że przekaz Sekstusa stanowi jedynie interpretację treści zawartych w platońskim Teajtecie i – wbrew praktyce wielu uczonych - nie może być brany pod uwagę jako niezależne źródło wiedzy o myśli Protagorasa.

Dans cet article, je me propose de reconstruire le cadre général de la pensée politique protagoréenne et de dégager ses conditions de possibilité à partir d’une analyse du mythe et des déclarations exposées dans le Protagoras. J’essaierai de montrer que la conception protagoréenne est axée sur les notions de loi et de citoyen d’une part, et sur la relation que le sophiste d’Abdère établit entre loi et nature de l’autre. Protagoras est le premier penseur dans l’histoire de la (...) philosophie grecque qui est en mesure de distinguer le niveau du social (marquant la deuxième phase du développement de la vie humaine) et le niveau du politique (marquant la troisième phase, représentée par la fondation de la cité). Dans ce cadre, j’établirai un parallélisme entre la conception protagoréenne et le concept kantien d’« insociable sociabilité ». J’articulerai enfin cette conception à la définition du sophiste qu’offre Protagoras dans le Théétète, en vue de mettre en évidence le rôle directif du sophiste par rapport au dèmos et son intervention active dans le processus de constitution de la loi, et d’éclaircir ainsi son rapport à la démocratie athénienne.

En el Gran Discurso de Protágoras, en el diálogo platónico que lleva su nombre, Platón pone en boca de Protágoras un mito acerca del origen, desarrollo y naturaleza del ser humano, que es de gran relevancia filosófica. Se expresa que los dioses crearon a los seres mortales desde dos elementos: la tierra y el fuego. A su vez, también asignaron dos titanes, Epimeteo y Prometeo, para que proveyeran a los mortales de sus facultades. ¿Acaso esto implica que la creación no (...) fue terminada por los dioses? ¿Hasta qué punto los dioses crearon enteramente al ser humano? ¿Podría afirmarse que este es un mito creacionista? El desarrollo de los seres vivientes puede dividirse en cuatro instancias. A lo largo de este artículo, se proponen distintos modelos hermenéuticos para responder los interrogantes mencionados anteriormente. (shrink)

Der Dialog Protagoras gehort zu den "kunstlerisch vollendetsten und sorgfaltigst gearbeiteten Dialogen," so Rudolf Hirzel. Von den Werken Platons hat Protagoras neben Der Staat am starksten die staatspolitische Theorie seit der Antike beeinflusst.".

The famous dispute between Protagoras and Euathlus concerning Protagoras’s tuition fee reportedly owed to him by Euathlus is solved on the basis of practical argumentation concerning actions. The dispute is widely viewed as a kind of a logical paradox, and I show that such treating arises due to the double confusion in the dispute narrative. The linguistic expressions used to refer to Protagoras’s, Euathlus’s and the jurors’ actions are confused with these actions themselves. The other confusion is (...) the collision between the pairs of incompatible actions ambiguously expressed by two different pairs of sentences, one of which is a propositionally consistent pair whereas the other is an inconsistent one. The actional paradox solution aims to clear up these confusions by means of two core borderlines, propositional and expressive, drawn between the actions and the propositions. The propositional distinction says that actions are empirical facts and they lack truth values unlike propositions, which are mental entities and are often employed for referring to the actions. This distinction helps to avoid the confusion between the empirical incompatibility of actions and the truth-functional inconsistency of propositions. The expressive distinction claims that although the same linguistic sentences can be used to refer both to actions and propositions, two empirically incompatible actions can be expressed both by a pair of inconsistent propositions as well as by a pair of consistent ones. Therefore, the action of Protagoras’s being paid may be linguistically symbolized in four different ways: Protagoras gets paid due to the verdict, Protagoras gets paid due to the contract that amount to Protagoras does not get paid by the contract and Protagoras does not get paid by the verdict respectively, and likewise for Euathlus’s actions. The two distinctions are used for classifying the two groups of paradox solutions, legal and logical, proposed so far depending on which of the two confusions they purport to escape from. The actional reconstruction of the paradox suggests that there is only one single agent in the dispute, Protagoras, while the other named Euathlus is a ‘phantom,’ which most probably was invented by Protagoras himself for the sake of creating this challenging sophism.

In this paper I want to do the following things. First I want to show that in the part of the Theaetetus where the relationship between knowledge and perception is examined, the concept of knowledge that is in question is very clearly characterized. We are left in no doubt as to what is to count as knowing. Secondly I want to unravel in some detail the case that Socrates puts on Protagoras’ behalf where he draws on what Protagoras (...) actually wrote ; as opposed to what he may have taught secretly to his pupils. Thirdly I wish to argue that if we let the dialogue speak for itself, it is manifest that this case put up on Protagoras’ behalf at 151 E-152C is not overthrown; it is not even shaken.In that part of the dialogue where the question is under examination whether or not knowledge and perception are the same, Socrates uses an idealized concept of knowledge. That is, he restricts the use of the word by setting down what he will consider to be the essential characteristics of knowledge, the sufficient and necessary conditions of its being instantiated. An excellent piece of philosophical procedure. (shrink)

In both Metaphysics Γ 4 and 5 Aristotle argues that Protagoras is committed to the view that all contradictions are true. Yet Aristotle’s arguments are not transparent, and later, in Γ 6, he provides Protagoras with a way to escape contradictions. In this paper I try to understand Aristotle’s arguments. After examining a number of possible solutions, I conclude that the best way of explaining them is to (a) recognize that Aristotle is discussing a number of Protagorean opponents, (...) and (b) import another of Protagoras’ views, namely the claim that there are always two logoi opposed to one another.

The presocratic philosopher Protagoras of Abdera (490–420 BC), founder of the sophistic movement, was famously agnostic towards the existence and nature of the gods, and was the proponent of the doctrine that 'man is the measure of all things'. Still relevant to contemporary society, Protagoras is in many ways a precursor of the postmodern movement. In the brief fragments that survive, he lays the foundation for relativism, agnosticism, the significance of rhetoric, a pedagogy for critical thinking and a (...) conception of the human being as a social construction. -/- This accessible introductory survey by Daniel Silvermintz covers Protagoras' life, ideas and lasting legacy. Each chapter interprets one of the surviving fragments and draws connections with related ideas forwarded by other sophists, showing its relevance to an area of knowledge: epistemology, ethics, education and sociology.

This paper argues, first, that one can render Protagoras’s view on the teach ability of political virtue coherent by distinguishing between the affect required for achieving it and the capacity for developing these affect into fully fledged virtues.

In Protagoras’ so called Great Speach, in Plato’s dialogue named after him, the Greek philosopher attributes the sophist a myth about the origin, development and nature of human beings, which has philosophical relevance. It is said that the gods created the mortal beings out of two elements, earth and fire. They assigned two titans, Epimetheus and Prometheus, to provide mortals with their faculties. Do this implies that creation had not been finished by the gods? To what extent do the (...) gods entirely create human beings? Is this mith a creationist one? In this paper, the development of living beings is divided in four stages, and different hermeneutic and explanatory models are proposed to adress the myth and answer the questions raised before.

Is virtue teachable? What should we value as an ideal? Is pleasure or perception the highest good that ought to be the object of our lives? Three of Plato's most important dialogues are brought together in a single volume to address these concerns which continue to occupy serious minds today. In the Protagoras Plato attempts to answer questions about the nature of virtue and whether it is inherent in humans or a subject capable of being taught. In the Philebus (...) he addresses the nature and content of the good and whether wisdom or pleasure is to be preferred. The Gorgias applies what is learned from the previous discussions to address larger issues, such as the proper functioning of society and the state and the individual's appropriate place within them.

This article aims at reconstructing the logic and assessing the force of Socrates' argument against Protagoras' 'Measure Doctrine' at Theaetetus 171a–c. I examine and criticise some influential interpretations of the passage, according to which, e.g., Socrates is guilty of ignoratio elenchi by dropping the essential Protagorean qualifiers or successfully proves that md is self-refuting provided the missing qualifiers are restored by the attentive reader. Having clarified the meaning of MD, I analyse in detail the broader section 170a–171d and argue, (...) against an extensive scholarly consensus, that it contains two slightly different formulations of the same argument, and not two distinct arguments, that Socrates does not highlight his own strategy at 171a–c as especially clever, and that his argument successfully shows that md turns out to be untenable for Protagoras himself when submitted to scrutiny in dialectical contexts, without aiming at proving its absolute falsehood. Finally, I clarify the philosophical import of the final image of Protagoras' momentary return from the underworld. (shrink)

This article seeks to present a detailed textual analysis of Protagoras’ Great Speech in Plato's Protagoras. I will argue that the concept of ἀρετή as it appears in the Great Speech is whittled down to a vague notion of civic duty. In this respect, Protagoras is bringing himself in line with the democracy, but in doing so the ἀρετή he claims to teach loses much of its initial appeal, particularly in the eyes of his aristocratic clientele. Nevertheless, (...) if thecontentof Protagoras’ Great Speech overlooks the abilities required to rise to political prominence, theformmost assuredly does not. As one would expect from Plato's Protagoras, his speech is replete with just that oratorical prowess his students might expect to acquire from him. This, in turn, has a number of interesting and important implications in the broader context of theProtagoras, in particular regarding the contrast or conflict between long speeches and short-answer dialectic. Moreover, although it has long been noticed that Protagoras neglects rhetoric and personal pre-eminence in his account, as far as I know there has not been any serious attempt to analyse the stylistic aspects of this masterful speech. Accordingly, both this and my attempt to interpret it within the economy of the dialogue are original. (shrink)

Der Beitrag untersucht die Bedeutung des Protagoras für die Entwicklung von Platons politischer Philosophie und Ethik anhand des gleichnamigen Dialogs. Im Mittelpunkt steht zunächst die epideiktische Rede des Protagoras, die die Fragen nach dem Wesen und der Lehrbarkeit der Tugend, nach der besten Erziehung sowie der besten politischen Verfassung aufwirft. Konkret werden in diesem Kontext die Auseinandersetzung um die Bewertung der Demokratie, das Verständnis der politischen Technik, das Verhältnis von Natur und Satzung und die Antizipation der späteren Aristotelischen (...) Differenzierung zwischen ethischen und dianoetischen Tugenden im _Protagoras_ analysiert. Durch all diese Punkte läßt sich schließlich nachdrücklich belegen, wie stark Platons eigener Weg von Protagoras bestimmt worden ist, sofern dieser für ihn auf anerkanntermaßen höchstem Niveau und auf eine geradezu paradigmatische Weise all die Irrwege beschreitet, die ihn zu einem idealen Antipoden von Platons eigenen Intentionen werden lassen konnten.

While defending the principle of non-contradiction in Metaphysics 4, Aristotle argues that the Measure Doctrine of Protagoras is equivalent to the claim that all contradictions are true; given all appearances are true (as the Protagorean maintains), anytime people disagree we get a true contradiction. This argument seems clearly invalid: nothing guarantees that actual disagreement occurs over every matter of fact. The argument in fact works perfectly, I propose, because the Protagorean view falls prey to a version of Fitch's “paradox” (...) of knowability. The proposed reading shows how Aristotle treats the Protagorean view at issue as an epistemic theory of truth distinct from the mere claim that all appearances are true (which other opponents put forward on different grounds) and reveals Aristotle's underlying concern with the modal collapse of possibility into actuality. The revised Protagorean view Aristotle confronts in a subsequent chapter is furthermore best understood as an attempt to avoid this Fitch-style result. (shrink)

Protagoras’ Grand Speech is traditionally considered to articulate a contractualist approach to political existence and morality. There is, however, a newly emerging line of interpretation among scholars, which explores a naturalist layer in Protagoras’ ethical and political thought. This article aims to make a contribution to this new way of reading Protagoras’ speech, by discussing one of its most elaborate versions.

In his theory of society Protagoras, one of the most influential sophists thinkers, applies a contractarian approach, similar in many respects to those of Locke, Hobbes and Rousseau.

He offers an evolutionary account of the development of human species, arguing that society is (...) a result of a contract among its members, based on commonly shared and taught social virtues. On the other hand, Protagoras is not a nihilist: In his account there is still a possibility of an expertise within the polis, related to the good of the particular community. (shrink)

Protagoras believes that all beliefs are true. Since Protagoras' belief that all beliefs are true is itself a belief, it follows from Protagoras' belief that all beliefs are true that Protagoras' belief is true. But what about the belief that Protagoras' belief is false? Doesn't it follow, by parallel reasoning and not at all trivially, that if all beliefs are true and there is a belief that Protagoras' belief is false, then Protagoras' belief (...) is false? (shrink)
