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)

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)

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 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.

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.

Ignorance is commonly assumed to be a lack of knowledge in Plato’s Socratic dialogues. I challenge that assumption. In the Protagoras, ignorance is conceived to be a substantive, structural psychic flaw—the soul’s domination by inferior elements that are by nature fit to be ruled. Ignorant people are characterized by both false beliefs about evaluative matters in specific situations and an enduring deception about their own psychic conditions. On my interpretation, akrasia, moral vices, and epistemic vices are products or forms (...) of ignorance, and a person who lacks knowledge is not necessarily ignorant. (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.

This article will contrast two portrayals of Protagoras: one in the "Theaetetus," where Socrates discusses Protagorean theory and even comes to his defense by imitating the deceased sophist; and another in the "Protagoras," where Socrates recounts his encounter with the sophist. I suggest that Plato wants listeners and readers of the dialogues to hear the dissonance between the two portraits and to wonder why Socrates so distorts Protagoras in the "Theaetetus." Protagoras in the "Protagoras" behaves (...) and speaks in ways that are incompatible with the Protagorean position presented in the "Theaetetus." . (shrink)

I advocate an ad hominem reading of the hedonism that appears in the final argument of the Protagoras. I that attribute hedonism both to the Many and to Protagoras, but my focus is on the latter. I argue that the Protagoras in various ways reflects Plato’s view that the sophist is an inevitable advocate for, and himself implicitly inclined toward, hedonism, and I show that the text aims through that characterization to undermine Protagoras’ status as an (...) educator. One of my objectives in the course of my arguments is to explore connections between the final argument of the Protagoras and the Man-Measure Doctrine as it is developed in the Theaetetus. (shrink)

This is the review of L. Regner's translation of Protagoras by Plato.

In the Protagoras, Socrates argues that what appears to be akrasia is, in fact, the result of a hedonic illusion: proximate pleasures appear greater than distant ones. On the face of it, his account is puzzling: why should proximate pleasures appear greater than distant ones? Certain interpreters argue that Socrates must be assuming the existence of non-rational desires that cause proximate pleasures to appear inflated. In this paper, I argue that positing non-rational desires fails to explain the hedonic error. (...) However, careful consideration of Socrates’ treatment of appearances reveals that he is not without resources to explain the illusion. I argue that in the Protagoras, appearances are imagistic mental representations that appear true but tend to be false. I suggest that proximate pleasures produce inflated hedonic predictions because we represent them more vividly than distant ones, yielding greater anticipatory pleasure which causes us to overestimate their magnitude.

Phone is a topic that is not so much explored and examined in Plato. Given eighteen times use of this word in Protagoras, this dialogue can be the suitable place to do a research about its meanings. Here the use of phone covers different subjects and facets of this word as an umbrella word so that in order to reach an ordered and meaningful understanding we place those aspects which are analogous in specific set and title.

I offer a reading of the two conceptions of the good found in Plato’s Protagoras: the popular conception—‘the many’s’ conception—and Socrates’ conception. I pay particular attention to the three kinds of goods Socrates introduces: (a) bodily pleasures like food, drink, and sex; (b) instrumental goods like wealth, health, or power; and (c) virtuous actions like courageously going to war. My reading revises existing views about these goods in two ways. First, I argue that the many are only ‘hedonists’ in (...) a very attenuated sense. They do not value goods of kind (b) simply as means to pleasures of kind (a); rather, they have fundamentally different attitudes to (a) and (b). Second, the hedonism that Socrates’ defends includes a distinction between kinds of pleasures: (a) bodily pleasures and (c) the pleasures of virtuous actions. This distinction between kinds of pleasures—some that do and some that do not exert the ‘power of appearance’—allows Socrates to address one of the central beliefs in the popular conception of akrasia, namely that it involves a special kind of unruly desire: non-rational appetites for pleasures like food, drink, or sex. Socrates replaces the motivational push of non-rational appetites with the epistemic pull of the appearance of immediate pleasures like food, drink, and sex. (shrink)

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

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

Plato’s Protagoras contains, among other things, three short but puzzling remarks on the media of philosophy. First, at 328e5–329b1, Plato makes Socrates worry that long speeches, just like books, are deceptive, because they operate in a discursive mode void of questions and answers. Second, at 347c3–348a2, Socrates argues that discussion of poetry is a presumptuous affair, because, the poems’ message, just like the message of any written text, cannot be properly examined if the author is not present. Third, at (...) 360e6–361d6, it becomes clear that even if the conversation between Socrates and Protagoras was conducted by means of short questions and answers, this spoken mode of discourse is problematic too, because it ended up distracting the inquiry from its proper course. As this paper 2 sets out to argue, Plato does not only make Socrates articulate these worries to exhibit the hazards of discursive commodifi cation. In line with Socrates’ warning to the young Hippocrates of the dangers of sophistic rhetoric, and the sophists’ practice of trading in teachings, they are also meant to problematize the thin line between philosophical and sophistical practice. By examining these worries in the light of how the three relevant modes of discourse are exemplifi ed in the dialogue, this paper aims to isolate and clarify the reasons behind them in terms of deceit, presumptuousness and distraction; and to argue that these reasons cast doubts on the common assumption that the dialogue’s primary aim is to show how sophistical rhetoric must succumb to Socratic dialectic.

One of the issues in regard to any language including classical Greek is phone. But it seems that Plato reflections on this notion are scattered, fragmented, and the like. With regard to this issue, by working on Protagoras dialogue I have tried to explore and explain the word/idea of phone that is used eighteen times in different meanings and significations.

The common 4th century B.C. view according to which Homer was regarded as a poet and a wise man, the leading and most honorable, to the point of being considered “the educator of Greece” (Pl. Resp. 606e-607a), is strongly supported by the Platonic dialogues. The works of Plato are the main available source to get to know not only the great pedagogical esteem for Homer, but also the several educational traditions that used or relied on Homeric poetry in Classical Athens. (...) We are certainly used to thinking of Socrates as standing out for contesting or blaming such customs and methods provided by rhapsodes, sophists and common people (Pl. Resp.; Ion; Hp. mi.). But conversely, he is also often depicted quoting, alluding to or remaking on Homeric passages when presenting his own views. Socrates even claims to feel a certain friendship or reverence for the poet and declares to be charmed by contemplating things through him, whom he considers to be amongst the few deserving to be called “philosophers” (Pl. Resp. 595b; 607c-d; Phdr. 278b-279b). The puzzling twofold nature of the Socratic attitude towards Homer, coupled with the fact that Plato would become a figure as honored as the poet was, led ancient literary criticism to focus on the Platonic use and sharing of material and techniques proper to Homeric poetry. Works like those of Dionysius of Halicarnassus, Maximus of Tyre, Longinus and above all Proclus, not only pointed out the philosopher’s debt to the poet, but even considered him to be an admirer of the Homeric genius unlike anyone else, and whose emulation basically attempted to reach and outperform the pedagogical power that the legendary poet had (Dion. Hal. Pomp. I, 13; Max. Tyr. Or. 26; [Longinus]; Subl. XIII, 2-3; Procl., In R. VI, 163.13-164.7; 202.7-205.23). With an analogous spirit, studies of contemporary Platonists suggest that the dialogues were shaped using the Homeric text, especially the Odyssey, as a template, and making Socrates appear as going through equivalent experiences to those of Odysseus’ “νόστος”. With respect to Protagoras, previous attempts focused on explicit references to books X and XI, placing the dispute with the sophist and the events at Callias’ house in the symbolic context of Odysseus’ encounter with Circe and the following journey into the underworld. I attempt to bring that reading one step further, paying special attention to the narrated character and the dramatic context for the singing of those episodes and the parallel ones in Protagoras. In first place, I consider the whole dialogue refiguring the episode in the Odyssey that works as a dramatic frame for the singing of Odysseus’ past adventures, the arrival at Phaeacia and the reception at Alcinous’ court. I regard Odysseus’ need to sing the Apologue as a call for hospitality to secure a safe passage home, working as a pattern for Socrates’ need of a tale at his own appearance in Athens to fulfill and secure a philosophical education in the city. In second place, I take into consideration the metanarrative dimension of such remaking. Since Socrates’ narration comes in response to a certain “Ὁμήρου ἐπαινέτης”, a “praiser of Homer” (Pl. Prt. 309b1), as Odysseus’ Apologue is to Demodocus the “ἀοιδὸς”, I examine how the dialogue could evince a dispute for pedagogical primacy amongst the different narratives and uses of poetry in Athens, a dispute that the Platonic narrative would attempt to surpass precisely by imitating Homer.

This article explores the motif of psychic nourishment in Plato’s Protagoras. It does so by analyzing what consequences Socrates’ claim that only a physician of souls will be able adequately to assess the quality of such nourishment has for the argument of the dialogue. To this purpose, the first section of the article offers a detailed analysis of Socrates’ initial conversation with Hippocrates, highlighting and interpreting the various uses of medical metaphors. Building on this, this section argues that the (...) warning Socrates utters against sophistry is much more complex than commonly assumed, and further that Socrates demonstrates his own skill as a physician of souls during this conversation. The second part analyzes the first half of Socrates’ discussion with Protagoras, arguing that Socrates here demonstrates another aspect of his expertise as a physician of souls by making Protagoras participate, although against his will, in bringing the unhealthy character of his teachings to light.

The position of this paper is that the political developments in Nigeria has bearing with Protagoras’ “man is the measure”. This dictum simply implies humanism. It is based on this that this work posits that humanism is what underlies and informs the political developments in Nigeria. Hence, it is argued that all the political eras in Nigeria have the well-being of human beings as their impetus. Thus, this work is premised on the need to meet up with the welfare (...) of Nigerians, in which its failure has resulted in the political developments experienced within the Nigerian-nation states. This conclusion is reached through critical analysis and evaluation. (shrink)

The Protagoras features the first known venture into detailed textual interpretation in the Western intellectual tradition. Yet if Socrates is to be taken at his wordat the close of his hermeneutic contest with Protagoras, this venture is to be regarded as a playful demonstration of the worthlessness of texts for aiding in the pursuit of knowledge. This essay is an attempt to view Socrates’ puzzling remarks on this point within their dramatic and historical contexts. I argue that, far (...) from having us lay our inherited texts aside, we can find in the Protagoras a reorientation to the linked activities of reading and dialogue, where we need not be forced to choose between merely using our own unaided voices and relying upon the (textual) voices of others in the project of philosophic education.

In Plato’s Protagoras, Socrates argues that ‘the many’ are confused about the experience they describe as ‘being overcome by pleasure’. They think the cause is ‘something other than ignorance’. He argues it follows from what they believe that the cause is ‘ignorance’ and ‘false belief’. I show that his argument depends on a premise he does not introduce but they should deny: that when someone is overcome by pleasure, the desire stems from a belief. To explain why Plato does (...) not make Socrates introduce this premise, the account I construct is speculative. It starts from the assumption that Plato is thinking through an understanding of human beings and what they must do to live good lives that he takes the historical Socrates to set out. (shrink)

The phenomenon of self-reference combines self-refutation in the case of Plato’s critics of Protagoras in “Theaetetus” and self-predication in the case of a difficulty which Plato himself faces developing the theory of ideas in “Parmenides”. The author of the article asserts that self-predication does not produce a negative impact on Plato’s metaphysics and in no way destroys the integrality of Plato’s philosophy: It is logically correct as are both his criticism of Protagoras’ relativism and the theory of ideas.

This literature review describes the current state of research on the Greek sophists. It draws on recent work on the beginnings of rhetoric, overviews of sophistic thought and case studies on Protagoras, Gorgias, Antiphon and Prodicus. It is shown that the traditional notion of a sophistic antithesis to philosophy has lost further ground: While earlier »rehabilitations« of sophistic thought still use the dichotomous distinction of philosophy und sophistic, now any generic talk of »the sophist« should better be regarded as (...) misleading.

The opening of Protagoras leads to a dramatic misunderstanding concerning the companion’s suspicion that Socrates has been in pursuit of the young Alcibiades. The remark that today Socrates paid him no attention and forgot about him, together with the announcement that the supposed reason for such a strange incident was the alleged wisdom of Protagoras, mitigates and confuses Socrates’ previous acknowledgement that indeed he has come from being with Alcibiades just now. The narration following the meeting with the (...) sophist reinforces that Alcibiades, while having been present and come to the aid of Socrates, was neither the aim of Socrates’ erotic pursuit, nor left the meeting to enjoy his company in private. However, previous studies claim that this impression could be false and prompted ironically by Socrates in the dialogue in order to redirect the attention of this companion, who would judge the relationship with Alcibiades inappropriate. This paper discusses previous studies and provides new textual evidence that could confirm that the drama indicates that Socrates, in spite of his dissimulation, actually appears to be in pursuit of Alcibiades. It also explains how Socrates’ feigned forgetting, which makes it possible to avoid the matter, may be read as a necessary precaution of the philosophy in its public appearance, to protect the course of a certain educational relationship with the youngster which has just begun.

In Metaphysics Γ 4-6 Aristotle argues that Protagoras is committed not just to denying the PNC, but also to asserting its contrary. In this paper, I offer an analysis of this commitment. I try to show that Aristotle is working with a specific idea in mind: a Protagoreanism ontologically linked to the flux doctrine, as Plato suggested in Theaetetus 152-160.

The paper is devoted to the sophistic method of "two-fold arguments" (antilogic). The traditional understanding of antilogic understood as an expression of agonistic and eristic tendencies of the sophists has been in recent decades, under the influence of G.B. Kerferd, replaced by the understanding of antilogic as an independent argumentative technique, having its own sources, essence, and goals. Following the interpretation of G.B. Kerferd, according to which the foundation of the antilogic is the opposition of two logoi resulting from contradictions (...) or opposites, necessarily associated with the contradictory character of the sensual world, in the paper it is argued that the philosophical basis of antilogic should be sought in the presentation of the views attributed to Protagoras and "adherents of flux" in Plato's dialogue Theaetetus.

A critical examination of the charge of self-refutation, particularly as leveled by orthodoxy-defending philosophers against those maintaining epistemologically unorthodox, especially relativistic or skeptical, views. Beginning with an analysis of its classic illustration in Plato’s *Theaetetus* as leveled against Protagoras’s “Man is the measure ...,” I consider various aspects of the charge, including logical, rhetorical, pedagogic, affective, and cognitive.

What is paradoxical about the Socratic paradoxes is that they are not paradoxical at all. Socrates famously argued that knowledge is sufficient for virtue and that no one errs willingly. Both doctrines are discussed in the Protagoras between Socrates and the Abderian sophist, however the argumentative line that Socrates chooses to follow in order to refute ‘the many’ has raised a serious degree of controversy among scholars. Is Socrates upholding the hedonistic view? Or, is he only trying to show (...) the bankruptcy of the explanation of akrasia as ‘being overcome by pleasure’ which ‘the many’ advocate? Socrates intends to do the latter, showing that this hedonistic explanation of akrasia leads to absurdity. Plato’s and Socrates’ identification of goodness with pleasure would mark a sudden and unexplained departure from their moral theories, and would render the Socratic denial of akrasia an argument with limited range –only for those assuming hedonism. If we are correct to hold that Socrates does not intend to identify the good with the pleasant, then we are immediately put against a new and much more difficult challenge; that is, to suggest how the Socratic denial of akrasia could regain its catholic plausibility against the commonsensical stance to akrasia, namely that people act against their best judgment due to their impotence to resist to motivational forces such as pleasure, pain, fear, passion and love. Socrates does not offer any other explicit account –apart from the hedonistic one- of how his doctrine could be catholically defended; hence the task of decoding the Socratic line of thought is far from an easy one. The key move in order to decode the puzzling Socratic doctrine is to understand how Socrates treats the notion of ‘knowledge’. For Socrates, moral knowledge is distinguished from mere belief; in this sense, only knowledge has the commanding power which enables one to sustain his best evaluative judgment against other motivational forces and only knowledge is sufficient for the virtuous conduct. By contrast, as mere belief is susceptible to other motivational forces like pleasure, pain, fear, etc. its possessor will, in turn, be susceptible to the revision of his intentions which derive from his best value judgment. In the Protagoras, Socrates implies that intentions grounded on belief can be ‘dragged around’ by desire; and according to my view in this paper, this Socratic stance allows a non-epistemic interpretation of his thesis. According to the traditional epistemic interpretation of the Socratic denial of akrasia, one’s wrongdoing is always a miscalculation that takes place on his practical syllogism. However, my understanding of the Socratic denial of akrasia allows cases of one even going against his best judgment, when his judgment is based on belief. In that sense, a judgment grounded on belief has insufficient power to guarantee that the chosen action will follow, whereas only judgments grounded on knowledge have a commanding and lordly power. For Socrates, everyone always goes for the good but only those with knowledge can infallibly discover and act on the good. Those with mere belief can only reach an apparent good, which may be good or bad. The motivation for the good is not unshakeable for those with mere belief since the grounding of their belief is scarcely strong enough to hold on the correct intention. Socrates therefore holds that the grounding of knowledge influences the motivational state of the moral agent. Thereupon, my interpretation differs from others in suggesting that for Socrates not all the cases of akrasia are cognitive mistakes in their judgment. Rather I hold, in opposition to the received stance on akrasia, that Socrates allows that one could act against his best judgment, when the latter is grounded on mere belief. (shrink)

This essay critically examines Rush Rhees’ Wittgensteinian account of language against the backdrop of Plato’s complete reversal of Protagoras’ axiom regarding man as the measure. Rhees jettisons Plato’s notion of Transcendence while retaining his emphasis on dialogue and unity. Despite trenchant points Rhees makes in that regard, it argues that Rhees’ view of language is in the end Protagorean. The essay traces out the problem of autonomy from rules to the practice to discourse itself, addresses Rhees’ missteps in relation (...) to instinctive reactions and intentionality, all of which are instructive in arriving at a better understanding of the relation between God and language.

The paper discusses the problem of the source of the analogies between philosophical outlook of the Sophists and the skeptical tradition of Pyrrho and his successors. Its main objective is to point out that the similarities in standpoints, arguments and methods between these philosophical phenomena result from the transmission of Plato’s Theaetetus. It is argued that main ideas (phenomenalism, subjectivism, relativity and indeterminacy of things, rejection of being and acceptance of becoming and constant flux, antilogical position consisting in opposing two (...) contradictory statements etc.) which in Theaetetus constituted so called “Secret Doctrine” (attributed by Plato to Protagoras and disciples of Heraclitus), after being criticized by Aristotle in his discussion about the principle of contradiction in Metaphysics (books IV and XI), were acknowledged by Pyrrho and, revived by Aenesidemus, can be found incorporated into the skeptical tradition in the works of Sextus Empiricus. -/- .

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)

Kafka's work provoked more than three decades of interpretations before Wagenbach provided information showing that Kafka was quite familiar with the work of Brentano and his Prague followers, including their unique conceptions of natural law, ethical concepts, and human acquaintance with them. Kafka took a lively interest in discussions in this Prague circle, and The Trial may without violence be read as a deliberate illustration for issues in philosophy of law as they would have been understood within this circle. This (...) does not require that it be read as a reflection of Kafka's personality, nor does it require that he accepted Brentano's views. Wagenbach demonstrated Kafka's familiarity with unique conceptions, in the work of Brentano and his Prague followers, of natural law and ethics. Issues involved in these conceptions are cogently illustrated in The Trial. K. is tried for violating a law which is no positive law but a necessary condition for all positive law since all positive laws imply that they ought to be obeyed. Brentano adamantly rejected all forms of nativism. The opposite of 'natural' in the phrase 'natural law' is not 'acquired' but 'conventional.' Acquaintance with natural norms is entirely acquired: persons having no such acquaintance can exist; K. is such a person. Natural norms, have a cognizable inherent correctness; any other norms oblige only through being authoritatively decreed. Conventional guilt or innocence is subject to influence. K.'s quest for a person to exert such influence on his behalf is evidence of his guilt. K. is unaware that absolute guilt is possible. In the Prometheus myth related by Plato's Protagoras, a sense of justice and right is necessary for politically organized society. Without insight into the natural sanction for correct positive laws, citizens cannot fulfill the duty rationally to choose positive laws: citizens will wrong one another, cities perish, humankind will be threatened. The myth gives important clues to the imagery of the parable "Before the Law." Every authentic act of willing requires that something be desired for its own sake. Since there is a plurality of intrinsic goods, authentic action requires recognizing the chosen action to be better than its alternatives. Acquaintance with good, evil, better, and worse is acquired, Brentano insisted, only by perceiving certain affects to be correct. Like judgments, affects are either blind or evident. Basic moral concepts arise like all others from perception. K. could become innocent by acquiring the lacking concepts. Then, actual acquittal would be just despite his guilt when arrested. His trial tests whether he is likely to experience intrinsically correct emotions. Guilt would be objective, independent of any finding by the Court. K.'s guilt entails his lacking any such concept of absolute guilt. He is convinced that guilt depends entirely on the Court, is altogether a matter of authority. This is K.'s delusion concerning his relation to the Court and the Law, the delusion illustrated by the legend, "Before the Law.". (shrink)

The Protagoras is the touchstone of Socrates’ moral intellectualist stance. The position in a nutshell stipulates that the proper reevaluation of a desire is enough to neutralize it.[1] The implication of this position is that akrasia or weakness of will is not the result of desire (or fear for that matter) overpowering reason but is due to ignorance. -/- Socrates’ eliminativist position on weakness of will, however, flies in the face of the common-sense experience regarding akratic action and thus (...) Aristotle was at pains to render Socrates’ account of moral incontinence intelligible. The key improvement Aristotle makes to Socrates’s model is to underscore that the conditioning of the akratic’s body plays a critical role in determining the power of one’s appetites and, accordingly, the capacity of one to resist the temptations these appetites present for rational evaluation. As Aristotle puts it, “For the incontinent man is like the people who get drunk quickly and on little wine, i.e., on less than most people.” (1151a 3-4). Aristotle presents what I shall call a somatic paradigm (i.e. the drunkard analogy) in order to tackle the problem of akrasia and it is this somatic solution that marks a significant improvement over Socrates’s intellectualist or informational model or so the tradition tells us. -/- In this paper, I wish to push back on the above Aristotelian explanation. I argue that when one fully examines Socrates’ account of weakness of will that Aristotle’s solution is less effective than is traditionally thought. In fact, Socrates can bring Aristotle’s model into his own; just as Aristotle absorbs what is right about Socrates’s model, namely, that akratic action utilizes reason but to a limited degree, Socrates in Meno (77C-78A) develops his own somatic model of weakness of will that connects to the intellectualist paradigm of the Protagoras. To achieve this rapprochement between the two models, I zero in on the description provided by Socrates of those individuals who desire bad things knowing they are bad as “ill-starred” or “bad spirited” (κακοδαίμων ). The “bad-spirited” is the coward and, in contrast to Aristotle’s drunkard, becomes fearful quickly from little danger. This additional somatic component, when connected to Socrates’s position on akrasia in Protagoras adds a new twist to Socrates’s model in the following way: while no one wishes to be ill-starred such that more harm than good will befall one, one may become so as a result of the bad choices one knowingly makes. -/- -/- [1] “After him came Socrates, who spoke better and further about this subject, but even he was not successful. For he used to make the virtues into sciences, and this is impossible. For the sciences all involve reason, and reason is to be found in the intellectual part of the soul. So that all the virtues, according to him arise in the rational part of the soul. The result is that in making the virtues into sciences he is doing away with the nonrational part of the soul and is thereby doing away with passion and character…” (Aristotle, Magna Moralia 1.1. 1182 a15-26).

In the Protagoras, Socrates argues that all the virtues are the very same knowledge of human wellbeing so that virtue is all one. But elsewhere Socrates appears to endorse that the virtues-such as courage, temperance, and reverence-are different parts of a single whole. Ambiguity interpretations harmonize the conflicting texts by taking the virtue words to be equivocal, such as between theoretical and applied expertise, or between a power and its deeds. I argue that such interpretations have failed in their (...) specifics and in general, as I defend an alternative that takes into account Socrates' higher purpose in testing others, namely to show them their ignorance of virtue.

Guided by the bold ambition to reexamine the nature of philosophy, questions about the foundations and origins of Plato’s dialogues have in recent years gained a new and important momentum. In the wake of the seminal work of Andrea Nightingale and especially her book Genres in Dialogue from 1995, Plato’s texts have come to be reconsidered in terms of their compositional and intergeneric fabric. Supplementing important research on the argumentative structures of the dialogues, it has been argued that Plato’s philosophizing (...) cannot be properly assessed without considering its intellectual debts. By detailed examinations of the practical, generic and textual origins of the dialogues, it has been shown how Plato’s chosen form of philosophical inquiry is deeply influenced by traditional forms of poetry, rhetoric, sophistry, and even medicine...

Special volume of "Thaumàzein - Rivista di Filosofia" dedicated to the theme of Socratic Eudaimonia and care for others. It is a multilingual volume comprising twenty papers divided into six sections with an introduction by Linda Napolitano. Edited by Santiago Chame, Donald Morrison, and Linda Napolitano. -/- Despite the appearances given by certain texts, the moral psychology of Socrates needs not imply selfishness. On the contrary, a close look at passages in Plato and Xenophon (see Plato, Meno 77-78; Protagoras (...) 358; Gorgias 466-468; Euthydemus 278; Lysis 219; Xenophon, Memorabilia III 9, 4-5) suggests that the “egoist”’s welfare depends upon the welfare of others (i.e. family, friends or the whole city). Since the welfare of his family, friends and city is part of his own eudaimonìa, the “egoist” (phìlautos) has a direct and intrinsic motive to promote the welfare of these others. -/- This multilingual issue explores the role that other peoples’ welfare plays in Socratic ethics. Special attention is paid to test-cases in which the principle that moral action is always good only for the agent seems to have no validity. I.e., under which circumstances is the self-sacrifice for the sake of others (such as the soldier’s self-sacrifice on the battlefield) good for the agent (as in Alcibiades I 115a-116d)? Essays deal with contradictions or tensions of this sort, and relate them to more general views on eudaimonìa held within Socratic literature. Comparison between different Socratic authors is used as a means to identify the distinctive features of Socratic eudaimonìa if compared to other Greek theories of happiness, such as the Aristotelian theory of philautìa (NE IX, 1166a-1166b; 1168a-1169b).

I examine two startling claims attributed to some philosophers associated with Megara on the Isthmus of Corinth, namely: Ml. Something possesses a capacity at t if and only if it is exercising that capacity at t. M2. One can speak of a thing only by using its own proper A6yor;. In what follows, I will call the conjunction of Ml and M2 'Megaricism' .1 The lit­ erature on ancient philosophy contains several valuable discussions of Ml and M2 taken individually .2 (...) But there is no discussion of them together, much less of their logical relations. I intend to remedy that lack, and to show why it is a lack worth remedying. My aims are both philosophical and historical. Inevitably, in saying anything new and interesting about Megaric views, I will be adopting assumptions scarcely free from controversy, and indulging in quite a bit of charitable recon­ struction. But the resulting picture is of considerable interest. For it explains why, although Ml and M2 seem to have little to do with one another, it is in fact small wonder that anyone who held one would hold the other, for, as I attempt to show, they entail each other. It explains why the Megarics are associated in the primary literature with the names of such diverse philosophical ancestors as Parmenides and Protagoras. And it explains why, although they are both false, Ml and M2 were claims taken seriously by both Plato and Aristotle, who in developing their own views on modality and language saw reason to mention Megaricism, and to argue against it.

The article focuses on a philosophical issue of the Renaissance humanism in William Shakespeare's Hamlet. The humanist tradition originated in Greece with the famous statement “Of all things man is the measure” (Protagoras of Abdera, 485-415 BCE), but it was not until the Renaissance that it reached its peak and became a doctrine. The article focuses on the humanism of the Renaissance, with its glorification of the image of the "giant man," which is mainly expressed in the work of (...) William Shakespeare. By pointing out the nature of Renaissance humanism, the article emphasizes Hamlet's play as a typical work of Renaissance humanism. (shrink)

Although relativism may be said to be one of the oldest doctrines in philosophy, dating back to the teachings of Protagoras in the 5th century B.C., when it comes to contemporary philosophy, there is no consensus on what makes a view qualify as "relativist". The problem is particularly accute in metaethics, since most of the views that up to a decade ago were described as “relativist” would be more accurately described as "contextualist" or even “expressivist” in light of the (...) distinctions currenty drawn in philosophy of language and semantics. In this chapter, we distinguish two construals of relativism, developed in sections 2 and 3 respectively: the “metaphysical” construal, based on the idea that there is no single, absolute, universal morality, and the “semantic” construal, based on the idea that the truth value of moral claims is relative to a set of moral standards, or moral practices, or some other suitable parameter. Section 1 introduces the core relativist ideas in an informal way, and warns against possible misinterpretations. (shrink)

In 1889, the German philologist Friedrich Blass isolated a section of Chapter 20 from Iamblichus’ Exhortation to Philosophy (mid- or late 3rd Century CE) as an extract from a lost sophistic or philosophical treatise from the late 5th Century BCE. In this article, I introduce the text, which is now known as 'Anonymus Iamblichi' (or 'the anonymous work preserved in Iamblichus') by appeal to its two main contexts (source preservation and original historical composition), translate and discuss all eight surviving fragments (...) in their entirety, and provide some closing remarks about its importance to this history of democratic thought. The text itself presents a series of very carefully interwoven arguments concerning the three “parts” of excellence (ἀρετή) – wisdom, courage, and eloquence – and their successful application in society. In the course of presenting this case, Anonymus Iamblichi comments on the conditions under which one should learn to be excellent (Fragments 1-2) and the ends to which one should direct one’s excellence (Fragments 3-4); he provides an anthropological discussion of the weaknesses of human psychology and its effects on the good man (Fragments 5-6) and an hypothetical thought experiment concerning the “Superman” (which naturally solicits comparison with Nietzsche’s übermensch) and his inability to overcome the multitude in a lawless state (Fragments 6 and 8); and a positive defense of law and justice, reflecting a pro-democratic philosophical perspective (Fragments 7-8) – a rara avis indeed in ancient philosophy.

In the "Republic," Plato has Socrates attack poetry’s use of mimēsis, often translated as ‘imitation’ or ‘representation.’ Various scholars (e.g. Blondell 2002; Frank 2018; Halliwell 2009; K. Morgan 2004) have noticed the tension between Socrates’ theory critical of mimēsis and Plato’s literary practice of speaking through various characters in his dialogues. However, none of these scholars have addressed that it is not only Plato the writer who uses mimēsis but also his own character, Socrates. At crucial moments in several dialogues, (...) Socrates takes on a role and speaks as someone else. I call these moments “Socratic mimēsis.” While previous commentators have noticed some of these moments, they have either overstated their rarity or they have not studied them collectively. My dissertation is the first in-depth investigation of this phenomenon in the dialogues. Socrates’ dramatic imitation of others is way of teaching in a voice separate from his own, and it is also a way for Plato to speak to, and to educate, different kinds of audiences. Although “Socratic mimēsis” occurs throughout the Platonic corpus, I focus on three passages from three different dialogues, which are paradigm instances: [1] in the "Crito" Socrates plays the part of ‘the Laws’ (50a-54c); [2] in the "Theaetetus" he acts the part of ‘Protagoras’ (166a-168c); and [3] in the "Menexenus" he recites a funeral speech learned from ‘Aspasia’ (236d-249c). Instead of one-sidedly reading the dialogues as either only literary works of art or as only a series of philosophical arguments, this study gleans philosophic insights from the literary and dramatic details of the dialogues. In chapter one I argue that in the "Crito" Socrates tries to convince Crito of a universal and absolute ethics based on never committing injustice, but Crito is not able to understand. In order to make Crito more just—but not yet at the level of Socratic ethics—Socrates creates ‘the Laws’ to persuade Crito to expand his personal notion of justice. Socrates instills a political obedience in place of Crito’s existing lawlessness as a second-best recourse. Plato expects the astute listener or reader to see the contrast between Socrates’ earlier ethical principles, said in his own voice, with what he says in the voice of ‘the Laws.’ In chapter two I argue that in the part of the "Theaetetus" where Socrates defends Protagoras (often called ‘the Defense’), Socrates, by imitating ‘Protagoras,’ is actually criticizing Protagorean relativism. The Protagorean theory cannot account for mimēsis and Socrates’ mimetic act performatively contradicts the identity of appearance and reality, which the theory presupposes. Finally, in chapter three I argue that in the Menexenus the funeral oration that Socrates recounts for Menexenus that he heard from ‘Aspasia’ is actually a disguised criticism of political rhetoric and of Athenian imperialism. Although the speech is never interrogated within the dialogue, Plato provokes the listener or reader outside the dialogue to question its message and to see how it conflicts with many of Socrates’ positions in other dialogues. Beyond reconsidering the long-standing and persistent view that Plato was against poetry and mimetic performance, I re-examine the role that performance and role-playing can have in philosophy and pedagogy more generally. Actors, by taking on other personas, and audience members, in observing actors and their actions, are both involved in acts of imagination that can expand their horizon of thinking and feeling.

Are the long, wildly inventive etymologies in Plato’s Cratylus just some kind of joke, or does Plato himself accept them? This standard question misses the most important feature of the etymologies: they are a competitive performance, an agôn by Socrates in which he shows that he can play the game of etymologists like Cratylus better than they can themselves. Such show-off performances are a recurrent feature of Platonic dialogue: they include Socrates’ speeches on eros in the Phaedrus, his rhetorical discourse (...) in the Menexenus, and his literary interpretation in the Protagoras. The paper compares these cases to work out the ground rules, purposes and implications of the Platonic agôn, and the Cratylus etymologies in particular. (shrink)
