Sextus Empiricus

Pyrrhonian skeptics, according to Sextus Empiricus, suspend judgment in the face of equally strong oppositions, but they also continue to investigate. This joint characterization has puzzled scholars: Why keep investigating if the evidence demands epochē? On this point, Sextus has been accused of muddled thinking at best and incoherence at worst. In this paper, I explain how investigative activity harmonizes with the suspensive mindset. My interpretation helps to explain several puzzling features of Pyrrhonian philosophy in addition to the idea that (...) one can both suspend judgment and continue investigating. (shrink)

I propose to dissolve the distinction between “rustic” and “urbane” interpretations of Sextus Empiricus’ account of Pyrrhonian assent to appearances. On the traditional picture, the “rustic” takes the skeptic to have no beliefs while the “urbane” takes the skeptic to have some “everyday” beliefs. I examine the distinction in two forms. First, in the original suite of papers by Frede, Burnyeat, and Barnes, I find that aside from a few differences in English terminology choice, the three authors substantially agree on (...) the interpretation of assent to appearances. Second, turning to the revised distinction proposed by Fine, I find that the two supposedly divergent interpretations give us pictures of the Pyrrhonist indistinguishable from each other on the basis of the skeptic’s actions or assent. The distinction dissolved, I propose a unified interpretation that expresses what I find to be the ultimate agreement between the two supposedly different camps. Finally, I turn to the question of the skeptical life and use this unified interpretation to argue that both an everyday life and an unconventional one are equally consistent with Pyrrhonian practice.

At Outlines of Pyrrhonism (PH) 2.227–8, Sextus Empiricus argues that certain entities which his adversaries hold to be one and the same for different individuals are in fact not. This he does by, among other things, considering the truth-value of sentences of which the subject is a common noun, thereby drawing an interesting connection between metaphysics and semantics. In this article, I provide a careful analysis of Sextus’ arguments at PH 2.227–8 and explore the origins and limits of such a (...) connection. In particular, I argue that Sextus’ argument at PH 2.227 probably reflects a Stoic argument against Aristotelian essences, thereby relying on specifically Stoic doctrines about universals and common nouns, whereas his next argument at PH 2.228 targets accidents. If this is true, it follows that the overall structure of PH 2.227–8 fits well with the typically Aristotelian distinction between essence and accident. (shrink)

Sextus Empiricus presents Pyrrhonism as a skeptical lifestyle that is appealing, in large part, because of the tranquility it appears to afford. Addressing concerns about the practicality of such a lifestyle, Sextus suggests that Pyrrhonists can lead sufficiently ordinary lives while suspending belief about everything unclear. Here, I aim to offer a partial examination of the practicality and appeal of Pyrrhonism from the Pyrrhonist’s perspective. In particular, I examine how a skeptic would likely respond if asked to consider his potential (...) use of problematic concepts in his daily life. I argue that, even if the Pyrrhonist’s skepticism is limited to certain types of controversial theoretical commitments, consideration of this issue would likely still cause him to worry that he is relying on beliefs about things unclear in his ordinary life. Along the way, I also hope to highlight some of the difficulties that a philosophically reflective person is likely to encounter if he is resistant to taking on philosophical commitments. (shrink)

This article is an investigation of the nature of suspension of judgement as it is conceived by Sextus Empiricus. I carry out this investigation by examining what I take to be Sextus’ most pertinent remarks on the topic and by considering them in the context of contemporary philosophical work on the nature of suspension. Against the more frequently encountered idea that Sextus is operating with a privative conception of suspension, I argue that Sextus instead has a metacognitive account of suspension, (...) whereby suspending constitutively involves acknowledging that one is not in a position to tell whether or not p.

Hermodorus of Syracuse, a Sicilian disciple of Plato, is reported by Simplicius to have set out a classification of beings, which is of a piece with an argument for principle monism (in Ph. 247.30–248.18 > F 5 IP2; 256.28–257.4 = F 6 IP2). A similar classification appears in Sextus Empiricus’ Aduersus mathematicos X (262–75), where it is officially ascribed to some ‘Pythagoreans’ (Πυθαγορικοί) or ‘children of the Pythagoreans’ (Πυθαγορικῶν παῖδες), but seems ultimately based on Early Academic material. Virtually all commentators (...) have read these classifications conjointly. More radically, both have been taken to record Plato's oral teaching and to give essentially the same categorial scheme, which is regarded as the most developed instance of a so-called ‘Academic doctrine of the categories’. This article re-examines these texts and provides an alternative reading. Section 1 focusses on Hermodorus and defends three theses: (1) there was never such a thing as an ‘Academic doctrine of the categories’; (2) Hermodorus does not seem to recount what Plato said, but to propose an integrated interpretation and defence of aspects of his thought; (3) Hermodorus’ pronouncements about principles are incompatible with other testimonies on Plato's unwritten teaching, notably Aristotle's. Section 2 moves to Sextus and defends a fourth thesis: (4) despite their similarities, the classifications of Hermodorus and Sextus’ Pyrhagoreans are considerably different, though perhaps originated from the same debate.

In this paper, I examine how the Mode of Infinite Regress functions in Pyrrhonian scepticism. I argue that it is used both to generate an infinite regress of reasons and to show that such infinite regresses are epistemically defective. I clarify precisely how this occurs while examining the Mode’s efficaciousness and whether ancient philosophers might have accepted infinite regresses of reasons. I ultimately argue that they would not for reasons which have hitherto not been adequately appreciated and which shed further (...) light on how the Mode of Infinite Regress functions, its efficacy, and the relevant notions of justification at stake.

In Sextus’ discussion of ‘place’ we find an attempt to insulate the philosophical questions about the conception of place and the ordinary answers to questions about where certain things are from one another. Common moves in dialectical practice against begging the question are used to delimitate the two contexts. Contrary to Myles Burnyeat’s interpretation, I argue, through close reading of the relevant texts, that there is no inconsistency in Sextus’ attempt.

Este libro recopila siete estudios que discuten algunas de las aportaciones de Aristóteles, Platón y Sexto Empírico en temas de argumentación filosófica, tiempo, causalidad y escepticismo radical. Algunas de las preguntas que abordo incluyen: ¿Qué papel debe tener la metáfora y la analogía en el discurso filosófico? ¿Cuáles son los presupuestos éticos de una discusión filosófica abierta y productiva y por qué a veces fracasa? ¿Cuál es el alcance y qué se debe responder ante el escepticismo radical? ¿Es el tiempo (...) una categoría fundamental para comprender la realidad? ¿Qué es una causa y cuántos tipos hay? El interés por la argumentación filosófica atraviesa todos los capítulos del libro. Sin embargo, este tema es más prominente en los caps. 1, 3, 4 y 5. Hay tres capítulos que analizan de manera detallada diversos aspectos de la metafísica Platónica, incluyendo la causalidad en el Sofista (cap. 4) y Fedón (cap. 6), así como el concepto del tiempo en el contexto de la cosmogonía del Timeo (cap. 8). Una tercera terna de capítulos desarrollan el escepticismo de Sexto Empírico (cap. 2, 5 y 7). Todos los capítulos fueron publicados con anterioridad en revistas especializadas y compilaciones en el lapso de doce años (de 2009 a 2022). Cinco capítulos fueron publicados originalmente en inglés, y presento aquí una traducción al español para poner estos textos al alcance de lectores hispanoparlantes. Los otros tres capítulos fueron publicados en libros y revistas en español y presento ahora una versión que corregida. (shrink)

In Hellenistic philosophy, one can find contrasting evaluations of the argumentative use of merely conceivable states of affairs. On the one hand, Epicureans discard any proposal that has no plausibility from the point of view of someone in possession of the relevant expertise. On the other hand, Sceptics regularly invoke views which one might conceivably hold, irrespective of the view’s epistemic credentials or whether or not it has or has ever had actual proponents. Since thought experiments often introduce scenarios involving (...) merely conceivable but non-actual states of affairs, the positions of Epicureans and Sceptics regarding conceivability can be transposed into different attitudes towards the method of thought experiments.

Hegel opens the first book of his Science of Logic with the statement of a problem: “The beginning of philosophy must be either something mediated or something immediate, and it is easy to show that it can be neither the one nor the other, so either way of beginning finds its rebuttal.” Despite its significant placement, exactly what Hegel means in his expression of this problem and exactly what his solution to it is, remain unclear. -/- In this book, Robb (...) Dunphy provides a detailed engagement with Hegel’s “problem of beginning”, locating it within Hegel’s account of significant approaches to the topic of beginning in the history of Western philosophy, as well as making an extended case for the influence of Pyrrhonian Scepticism on the beginning of Hegel’s Logic. Dunphy’s discussion of the various putative solutions that Hegel might be thought to put forward contributes to debates concerning Hegel’s views on the methodology of logic, the relation between his Logic and his Phenomenology of Spirit, and differences between his Encyclopaedia presentation of logic and that of his greater Science of Logic. -/- Hegel and the Problem of Beginning also functions as a critical commentary on Hegel’s essay, “With what must the beginning of the science be made?” which should be of interest to both researchers and students working on the opening of Hegel’s Logic.

Parallels between the ancient Hellenistic philosophies of the Stoics and Epicureans, on the one hand, and modern cognitive psychotherapy, on the other, are well known and a topic of current discussion. The present article argues that there are also important parallels between Pyrrhonism, the third of the major Hellenistic philosophies, and the currently state-of-the-art “3rd wave” cognitive-behavioral therapies in general, and Acceptance and Commitment Therapy (act) in particular. This provides a crucial insight into Pyrrhonism: understanding Sextus’ term adoxastos using the (...) technical act term ‘defusion’ illuminates the psychological condition of the Pyrrhonist and explains why the apraxia objection against Pyrrhonism is misguided.

Hellenistic philosophy concerns the thought of the Epicureans, Stoics, and Skeptics, the most influential philosophical groups in the era between the death of Alexander the Great and the defeat of the last Greek stronghold in the ancient world. The Routledge Handbook of Hellenistic Philosophy provides accessible yet rigorous introductions to the theories of knowledge, ethics, and physics belonging to each of the three schools. It explores the fascinating ways in which interschool rivalries shaped the philosophies of the era, and offers (...) unique insight into the relevance of Hellenistic views to issues today, such as environmental ethics, consumerism, and bioethics. Eleven countries are represented among the Handbook's thirty-five authors, whose chapters were written specifically for this volume and are organized thematically into six sections: I. The people, history, and methods of Epicureanism, Stoicism, and Skepticism. II. Earlier philosophical influences on Hellenistic thought, such as Aristotle, Socrates, and Presocratics. III. The soul, perception, and knowledge. IV. God, fate, and the primary principles of nature and the universe. V. Ethics, political theory, society, and community. VI. Hellenistic philosophy's relevance to contemporary life. Spanning from the ancient past to the present, this Handbook aims to show that Hellenistic philosophy has much to offer all thinking people of the twenty-first century. (shrink)

Anaxarchus accompanied Pyrrho on Alexander the Great’s expedition to India and was known as “the Happy Man” because of his impassivity and contentment. Our sources on his philosophy are limited and largely consist of anecdotes about his interactions with Pyrrho and Alexander, but they allow us to reconstruct a distinctive ethical position. It overlaps with several disparate ethical traditions but is not merely a hodge-podge; it hangs together as a unified whole. Like Pyrrho, he asserts that things are indifferent in (...) value and that realizing this indifference leads to contentment. But this doctrine of indifference is rooted in Democritean atomism. And in his pursuit of pleasure and dismissiveness of conventional standards of what is just, noble, and pious, Anaxarchus is closer to fifth century thinkers such as Aristippus, Antiphon, and Critias.

In Against the Musicologists (Math. 6), Sextus uses two types of arguments against musicology. Some would argue that a science of music – does not contribute to a happy life, while others deny that such a science has ever been established. Since the respective beliefs that musicology exists and that it benefits those who have mastered it are fine specimens of dogmatism, all Sextus has to do is to set the naysayers and the believers against each other in good Pyrrhonian (...) fashion. If their accounts balance each other out, he can go on to suggest that reasonable inquirers will suspend judgement as to the truth about these matters, while leaving everyday musical practice intact. Against the Musicologists thus lends itself to being read as an attempt to display the Sceptical capacity to motivate suspension of judgement in a specific domain where the Sceptic has detected dogmatic belief. -/- In what follows, I develop a reading of the treatise along these lines. In Section 5.1, I argue that Sextus’ polemical engagement with philosophical musicology sits well with the project of the treatise to which it belongs, and with a plausible understanding of his philosophical position as presented in the Outlines of Pyrrhonism (Pyr.). Then I turn to the two kinds of arguments that are contrasted by Sextus as being ‘more dogmatic’ and ‘more aporetic’ in spirit. After their brief presentation in Section 5.2, explaining the nature of their contrast by pointing to the diverging agendas that they originally served, I give an overview of both as ultimately aiming at epochē in Sections 5.3 and 5.4. Finally, in Section 5.5, I push back against readings that take the treatise to present a deviation from the suspensive outlook. (shrink)

Pyrrhonian inquiry responds to the hope of intellectual tranquillity, and aims at the achievement and maintenance of said tranquillity. According to the Tranquillity Charge, philosophical inquiry aims at the truth; hence, insofar as Pyrrhonian inquiry aims at tranquillity, it does not qualify as philosophical inquiry. Furthermore, Pyrrhonian philanthropy rests on the Partisan Premise, i.e. the claim that all philosophers aim at the removal of psychological disturbance. I show that the origin-story of Pyrrhonism evades the Tranquillity Charge, and that the Partisan (...) Premise is not as partisan as it seems. Unlike previous attempts, my reconstruction preserves all tranquillity-related features of Sextan Pyrrhonism. (shrink)

It has been argued that Pyrrhonists will have trouble acquiescing in the religious practices of their compatriots, since those practices depend on beliefs that are supposedly eliminated by suspension of judgement. According to this objection ..., the Sceptic’s religious behaviour will be inescapably disingenuous. As a way out of this predicament, some interpreters have suggested that the sort of religion that Sextus was familiar with did not require the kind of belief that is subjected to Sceptical examination. This, however, acquits (...) Sextus of the charge of insincerity at the price of taking religious behaviour to be a culturally contingent exception to, rather than a standard case of, Pyrrhonian conduct. Another worry concerns the fixity of Sextus’ philosophical agenda. The argument in PH 3 concludes that, if one goes by what dogmatic philosophers have to say, one will be forced to think that god is inconceivable. By contrast, the first part of the M 9 section on theology argues not for suspension of judgement across the board, but only for the more modest claim that several noteworthy explanations of the emergence of religious belief are unsatisfactory. Insofar as this is the case, M 9 fails to live up to the standard set by PH 3, a failure due either to authorial incompetence or to a difference in philosophical objective. If that is the case, then the two discussions cannot be read as successful examples of the same philosophical outlook. In this paper, I argue for a comprehensive reading of Sextus’ take on religious matters that responds to these worries. In the first half of the paper, I present the two caveats as formulating a uniform agenda concerning theology (Section 1) which is further consistent with the Pyrrhonian stance as presented in PH 1 (Section 2). I show not only that Sextan Sceptics are able to engage in ordinary religious practices, but also that they can do so whether or not their cultural environment takes these practices to depend on holding dogmatic beliefs. In the second half of the paper, I argue by way of a detailed analysis that both PH 3 and M 9 are intended to motivate suspension of judgement about highly specific dogmatic tenets, and while their sources and targets might change, their intended outcome remains the same. The argument in PH 3, often understood as a sort of ‘master argument’ aimed at disarming a broad theistic consensus, depends in fact on peculiar commitments concerning the nature of inquiry (Section 3). The conceptual section of M 9 incorporates explicitly dogmatic—and quite plausibly Epicurean—material in order to argue for suspension of judgement about yet another issue, namely, the question of the natural or conventional origin of the concept of god (Section 4).

Two versions of Peri tou mē ontos ptmo by Gorgias, related by an Anonymous Author MXG and by Sextus Empiricus SE, have been alternatively accredited by scholars according to their disposition to seek a doctrine or a rhetorical- communicational dimension respectively with the first tendency prevailing. Comparing the ptmo to the rest of Gorgiasʼ works, we verify and clearly demonstrate how SE manages to convey a precise modus argumentandi. In effect, SE shows Gorgias’ demonstrative reasoning as employing: 1 the application (...) of demonstrandum and quod erat demonstrandum typical of Gorgiasʼ speeches, reinforced by a substantial and abundant use of verbs of explanation and demonstration, especially in comparison to the rest of the same Against the Logicians’ section. Otherwise, MXG reduces this lexicon to the more generic phēmi; 2 the continuous employment of the reductio ad absurdum, like in all of Gorgias’ works; 3 a very refined formulation of the principle of non-contradiction §67, similar to the one seen in Pal. 25. In addition, MXG is accurate in the discussion of some arguments as in the third kephalaion, however, presents as an overcorrected interpreter, more interested in questioning Gorgias than reporting his original text, also directly referring to Zeno, Melissus, and Leucippus. The context of the ptmo in SE’s work the structure presented leads us to believe that SE had the text or at least an accurate summary of the ptmo different from MXG. The aims of this paper are: 1 to demonstrate that SE shows well the Gorgianic demonstrative reasoning and, for this specific reason, he is reliable and valuable resource for us; 2 to hypothesise that SE’s version is based on and independent as yet unknown source.

The standard “gladiatorial” interpretation of the Modes of Agrippa has undergone several recent attacks. Scholars have criticized it because it seems to portray the skeptic as a dogmatist about logical support and because it does not treat all five Modes as part of the system. Although some have attempted to patch up the standard interpretation to address these issues, I raise a further problem: The gladiatorial interpretation cannot make sense of the skeptic using the Modes on herself, to suspend her (...) own judgment. In light of these problems, I propose a fresh interpretation: The Agrippan Modes should be understood, not as arguments (or argument forms), but as types of dialectical challenge that the skeptic can use in an endless inquiry into any dogmatic position.

The majority of the excerpts traditionally taken to derive from a planned book 8 of Clement of Alexandria’s Stromateis concern the theory of demonstration (apodeixis) and related matters of logic. The suspension of judgement (epochē), a recognisably sceptical response to disagreement and a lack of demonstrative certainty, receives two brief treatments in this context. Apart from an attempted refutation of scepticism which points to the allegedly self-refuting character of universal epochē (5.15.2–16.3), the text also includes an account of the causes (...) that lead one to suspend judgement (7.22.1–4). ... First, I will give a brief overview of both the argument from self-refutation employed in the first Clementine excerpt and Sextus Empiricus' rejection of a related argument. I will argue that the comparison does not support definite claims about the origin of the Clementine material (section 1). Then I will discuss the second excerpt, which offers a series of remarks on the causal origin of epochē (section 2). I will then contrast it to Sextus’s account of the origin of suspensive disposition in terms of originative principles (archai) rather than causes (aitiai), arguing that Sextus’s formulation allows for a more nuanced sceptical position (section 3). In conclusion, I will briefly consider possible views on the relevance of this material, or the lack thereof, for Clement’s Christian project (section 4). (shrink)

How can we quiet the mind? How can we prevent it from endlessly worrying away at philosophical questions that serve only to keep us awake at night, with no hope of ever being resolved? Simply ignoring them is not an option, since they lurk around the corner of every decision; nor will argument suffice, argument being merely a continuation of philosophy. What we need, again, is not a theory but a method, one in which each claim is systematically juxtaposed against (...) its opposite, together with evidence just compelling enough to allow the two of them to cancel each other out. It is this method that Beckett’s Trilogy—Molloy, Malone Dies, The Unnamable—crucially offers its readers. A latter-day work of ancient skepticism, it begins from the same premise, aims at the same telos, and employs the same devices along the way. What it provides, in the end, is not insight and not inspiration but the opportunity to detach ourselves from our desire for certainty and to achieve, for the first time, an enduring peace of mind.

Luca Castagnoli, Ancient Self-Refutation. The Logic and History of the Self- Refutation Argument from Democritus to Augustine, Cambridge: Cambridge University Press 2010, pp. XX+394. Hardback, ISBN 9780521896313. -/- Abstract. In his book Ancient Self-Refutation L. Castagnoli rightly observes that selfrefutation is not falsification; it overturns the act of assertion but does not prove that the content of the act is false. He argues against the widely spread belief that Sextus Empiricus accepted the self-refutation of his own expressions. Castagnoli also claims (...) that Sextus was effective in answering to the self-refutation charge. The achievement of the book is the disperitropécovery that in passages where Sextus seems to embrace the selfrefutation of his expressions (PH 1.14-15), he does not use the term peritropé, technical for self-refutation, but the term perigraphé, which means self-bracketing. Selfbracketing is weakening one’s own thesis, but not overturning it. Castagnoli claims that Sextus embraces the self-bracketing of his expressions, but never accepts their selfrefutation. However, Castagnoli is not right in saying that self-refutation is a shameful mistake for everybody. The mature skeptic cannot even think that self-refutation is wrong, because it would be a dogmatic view. Sextus seems to accept self-refutation at the end of Against the Logicians, where he presents the argument against proof and the metaphor of the ladder (M 8.480-1). Regardless of Sextus’ declarations, we have reason to think that he does not avoid self-refutation in a pragmatic sense. Self-bracketing of his position is not a consistent dialectical strategy, as Castagnoli writes, but the end of a rational discussion. Sextus avoids absolute self-refutation (we cannot falsify what he suggests), but he is unable to avoid pragmatic self-refutation (there is no way to assert his position without contradiction). This is the case even if Sextus refuses to assert his position. (shrink)

This chapter presents Gustave Flaubert’s Madame Bovary and Samuel Beckett’s Trilogy as modern fictions with ancient-skeptical ambitions. Whether in the affective domain (Flaubert) or in the cognitive (Beckett), the aim is to help the reader achieve a position of studied neutrality—ataraxia, époché—thanks not to an a priori decision but to the mutual cancellation of opposing tendencies. Understanding Flaubert and Beckett in this way allows us, first, to enrich our sense of what “catharsis” may involve; second, to see why the apparently (...) odious Charles, in Madame Bovary, suddenly becomes a deeply touching figure; and third, to recognize the severe limitations of empathy-based moralist theories of fiction.

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.
