Protagoras

This paper discusses two broadly logical issues related to Protagoras’ measure doctrine (M) and the self-refutation argument (SRA). First, I argue that the relevant interpretation of (M) has it that every individual human being determines all her own truths, including the truth of (M) itself. I then turn to what I take to be the most important move in the SRA: that Protagoras recognises not only that his opponents disagree with him about the truth of (M), but also that they (...) hold that (M) is false simpliciter. By recognising that his opponents do not make the relativising concession he makes for them, he is forced to accept that (M) is false. I go on to argue that several other defenders of the SRA end up with a regress which is difficult to end and might not favour anti-Protagoreans. On my reading, by recognising what his opponents believe, Protagoras is barred from adding qualifiers, and the possible regress doesn’t get off the ground. I conclude with brief discussions of how Protagoras might try to avoid the result of the SRA and the argument’s role in this part of the Theaetetus. (shrink)

The paper discusses the debate on the human nature in the sophistic thought. Focusing on the "nature-culture" controversy it presents the evolution of the views of the sophists: from Protagoras' optimistic contention of the progress of mankind and his appraisal of culture to its criticism and the radical turn to nature in Antiphon, Hippias, Trasymachos, and Callicles. The paper aims at presenting the analysis of the ongoing discussion, with the stress laid on reconstruction of the arguments and concepts as well (...) as the attitudes that are associated with various positions of this debate. -/- .

Excerpt from Forschungen zur Geschichte des Erkenntnissproblems im Alterthum: Protagoras, Demokrit, Epikur und die Skepsis Welches sachliche Band die hier vorliegenden Abhandlungen verknupft sagt wohl dem Kundigen ein Blick auf die Ueber schriften. Der Zusammenschluss liegt in den drei Arbeiten uber die Skepsis. Das nahe Verhaltniss der Skepsis zu Protagoras ist langst im Allgemeinen anerkannt, doch im Einzelnen noch keines wegs hinreichend erforscht. Auf ihre kaum minder engen Be ziehungen zu Demokrit Epikur ist man seit kurzerer Zeit erst aufmerksam geworden; (...) in dieser Richtung durften am ehesten neue Aufschlusse erwartet werden.

Despite Protagoras’ infamous reputation for corrupting his students, his “Great Speech” (Plato,Protagoras 320c-328d) presents one of the most important arguments in the history of ethics. Refuting Socrates’ contention that virtue must be unteachable since even the best of men cannot raise good children, Protagoras argues that everyone is capable of learning the difference between right and wrong.

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.

This paper argues that essential features of Feyerabend's philosophy, namely his radicalization of critical rationalism and his turn to relativism, could be understood better in the light of his engagement with early Greek thought. In contrast to his earlier, Popperian views he came to see the Homeric worldview as a genuine alternative, which was not falsified by the Presocratics. Unlike socio–psychological and externalist accounts my reading of his published and unpublished material suggests that his alternative reconstruction of the ancient beginnings (...) of the Western scientific tradition motivate and justify his moderate Protagorean relativism.

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.

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 character Protagoras in Plato's Protagoras holds similar views to the one in the Theaetetus, and faces similar problems. The dialogue considers issues in epistemology and moral epistemology, as a central theme. The Protagorean position is immune from Socrates' attacks, and Socrates needs Protagorean methods to make any impact.

This is the translation of Protagoras' life from Diogenes Laertius' "Lives of eminent Philosophers" (IX, 8).

The paper is concerned with the medical and the biological sources of Protagoras' views.

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.

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)

Relativism was first formulated in Western philosophy by Protagoras in the fifth century BC. Protagoras is famous for his claim that 'man is the measure of all things'. Mi-Kyoung Lee examines this and the work of Plato, Aristotle, and Democritus"--Provided by publisher.
