Throughout the history of philosophy, skepticism has posed one of the central challenges of epistemology. Opponents of skepticism--including externalists, contextualists, foundationalists, and coherentists--have focussed largely on one particular variety of skepticism, often called Cartesian or Academic skepticism, which makes the radical claim that nobody can know anything. However, this version of skepticism is something of a straw man, since virtually no philosopher endorses this radical skeptical claim. The only skeptical view that has been truly held--by (...) Sextus, Montaigne, Hume, Wittgenstein, and, most recently, Robert Fogelin--has been Pyrrohnian skepticism. Pyrrhonian skeptics do not assert Cartesian skepticism, but neither do they deny it. The Pyrrhonian skeptics' doubts run so deep that they suspend belief even about Cartesian skepticism and its denial. Nonetheless, some Pyrrhonians argue that they can still hold "common beliefs of everyday life" and can even claim to know some truths in an everyday way. This edited volume presents previously unpublished articles on this subject by a strikingly impressive group of philosophers, who engage with both historical and contemporary versions of Pyrrhonian skepticism. Among them are Gisela Striker, Janet Broughton, Don Garrett, Ken Winkler, Hans Sluga, Ernest Sosa, Michael Williams, Barry Stroud, Robert Fogelin, and Roy Sorensen. This volume is thematically unified and will interest a broad spectrum of scholars in epistemology and the history of philosophy. (shrink)

According to Sextus Empiricus, (i) the principal aim of Pyrrhonian skepticism is to achieve tranquility, and (ii) the skeptic is uniquely positioned to realize this aim. I challenge (ii) by arguing that the value nihilist—who believes that nothing is good or bad—can achieve the exact same tranquility as the skeptic. From this comparison I draw important conclusions about the relations among skepticism, tranquility and the value of knowledge.

This paper applies speech-act theory to craft a new response to Pyrrhonian skepticism and diagnose its appeal. Carefully distinguishing between different levels of language-use and noting their interrelations can help us identify a subtle mistake in a key Pyrrhonian argument.

In his Reflective Knowledge, Ernest Sosa offers a theory of knowledge, broadly virtue-theoretic in character, that is meant to transcend simple ways of contrasting "internalist" with "externalist" or "foundationalist" with "coherentist" approaches to knowledge and justification. Getting beyond such simplifications, Sosa thinks, is the key to finding an exit from "the Pyrrhonian Problematic": the ancient and profound skeptical problem concerning the apparent impossibility of validating the reliability of our basic epistemic faculties and procedures in a way that escapes vicious (...) circularity. Central to Sosa's anti-skeptical strategy is the claim that there are two kinds of knowledge. His thought is that animal knowledge, which can be understood in purely reliabilist terms, can ground justified trust in the reliability of our basic cognitive faculties, thus elevating us to the level of reflective knowledge. I offer a sketch of an alternative approach, linking knowledge and justification with epistemic accountability and responsible belief-management, which casts doubt on the idea that "animal" knowledge is knowledge properly so-called. However, it turns out that this approach is close in spirit to Sosa's. I suggest that the differences between us may rest on a disagreement over the possibility of providing a direct answer to the Pyrrhonian challenge. (shrink)

For Richard Rorty the autonomy of philosophy and the idea of an ahistorical criterion of truth are ideas that stand or fall together. This article challenges that assumption. However, before proceeding to this criticism, it is necessary in this section of the article to provide some rudimentary exposition of Rorty's position.Richard Rorty wished to subjugate philosophy to history. He announced this position in Philosophy and the Mirror of Nature (1979), and his opinion on this matter did not change substantially in (...) any subsequent work. He argued that although it might be interesting to read the great philosophical texts of the past as having something to say to us directly (as proposed by Ryle and Austin), or .. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.3 (2001) 351-383 [Access article in PDF] Hume's Pyrrhonian Skepticism and the Belief in Causal Laws Graciela De Pierris Hume endorses in no uncertain terms the normative use of causal reasoning. The most striking example of this commitment is Hume's argument in the Enquiry against the possibility of miracles. The argument sanctions, in particular, the use of scientific reflection on uniform (...) experience issuing in causal laws of nature (E 114): "A miracle is a violation of the laws of nature; and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience can possibly be imagined." 1 These words should give us pause; for how can Hume so confidently say, after his skeptical conclusions concerning our causal beliefs, that "a firm and unalterable experience has established" the laws of nature, and that we can therefore produce "proofs" against miracles? The Treatise gives rise to the same puzzle. In this text, too, Hume confidently prescribes methodical reflection based on causal reasoning. For example, in Book One, Part Three, Section Fifteen, Hume offers eight "Rules by which to judge of causes and effects." These rules are more than descriptions of our natural causal inferences. They are meant to guide us in making better causal inferences; in Hume's words they "ought to regulate" our probable reasoning since (T 149): "by them we learn to distinguish the accidental circumstances from the efficacious causes." 2Moreover, Hume consistently takes Newtonian science as a model for the proper employment of causal inferences in inquiries into matters of fact and, [End Page 351] in particular, as a model to be followed in his own science of human nature. 3 This paradigm of what the science of nature ought to be is understood by Hume as an inductive, experimental inquiry. 4 In the Enquiry, for example, Hume uses the label "sciences" for "politics, natural philosophy, physic, chemistry, &c." and in the preceding discussion argues that these sciences are not a priori but are based on causal reasoning (E 164-165). Thus, there are for Hume inquiries into matters of fact and existence that amount to more than blindly following natural propensities and habit. The sciences and many of our causal inferences in common life involve more than mere belief as a sentiment. They involve, in addition, careful reflection that results in improved causal inferences and thus provides normative standards. Yet, in thus upholding the normative use of causal reasoning in science and in everyday life, Hume appears to contradict his own radical skeptical conclusions concerning our knowledge of causation and induction. I here propose a novel way to resolve this puzzle.To acknowledge the existence of a puzzle, however, amounts to accepting the now controversial view that Hume provides, and takes at face value, a radical skeptical argument concerning our knowledge of causation and induction. 5 Moreover, the attempt to resolve this puzzle involves rejecting the suggestion [End Page 352] that Hume, without awareness or concern, happily holds flatly inconsistent views. 6 It also goes against the more sophisticated suggestion that Hume lightly alternates among different psychological moods, or perhaps different perspectives, which might eventually issue in results that contradict each other but are sufficiently localized so as to prevent serious conflict. Such a view might lead us to conceive Hume's texts as an unstructured and arbitrary patchwork of reflections, driven by different psychological moods or by the embellishments of a radiant literary style. This kind of reading is unacceptable as an interpretative tool, however, as H. J. Paton has acutely noted in his criticism of the patchwork interpretation of Kant's Critique of Pure Reason. 7 For such a reading would place no constraints at all on the task of establishing which parts of Hume's text belong to which moods or perspectives. The suggestion that Hume offers an unstructured patchwork of reflections masks the novel and systematic distinction Hume draws between his radical philosophical... (shrink)

What was it like to be a practitioner of Pyrrhonist skepticism? This important volume brings together for the first time a selection of Richard Bett's essays on ancient Pyrrhonism, allowing readers a better understanding of the key aspects of this school of thought. The volume examines Pyrrhonism's manner of self-presentation, including its methods of writing, its desire to show how special it is, and its use of humor; it considers Pyrrhonism's argumentative procedures regarding specific topics, such as signs, space, (...) or the Modes; and it explores what it meant in practice to live as a Pyrrhonist, including the kind of ethical outlook which Pyrrhonism might allow and, in general, the character of a skeptical life - and how far these might strike us as feasible or desirable. It also shows how Pyrrhonism often raises questions that matter to us today, both in our everyday lives and in our philosophical reflection. (shrink)

Early in Outlines of Pyrrhonism Sextus Empiricus writes.

Is skeptical theism tenable once one acknowledges, as proponents of that view do, one's cognitive limitations vis-à-vis religious matters? In this article, I aim to answer that question both by examining the apparent radical skeptical implications of the skeptical component of skeptical theism and by comparing this view with fideism and Pyrrhonism, which also lay emphasis on our cognitive limitations. My ultimate purpose is to determine which of the three stances it makes more sense to adopt once the limitations of (...) human cognitive powers are recognized. (shrink)

This dissertation focuses on the philosophy of Sextus Empiricus, a skeptic who provides the most complete account of Pyrrhonian skepticism that survives from antiquity. In particular, this dissertation examines Sextus' account of skeptical assent, the attitude that structures and informs the life of the skeptic. Accordingly, this dissertation has two aims: first, to elaborate and defend a novel method of interpreting Sextus' claims and concepts, one based on their significance in ordinary life and language; and, second, to apply (...) this method to Sextus' claims about the nature of skeptical assent in order to generate a novel account thereof. In the first chapter, the most widely-held and influential interpretations of skeptical assent are elaborated and taxonomized. It is argued that all these interpretations neglect to pay sufficient attention to the self-reflexivity of Sextus' skepticism, in consequence of which Sextus' own claims about skeptical assent must be understood as expressing skeptical assent. It is argued, moreover, that this neglect of self-reflexivity cannot be remedied without abandoning these interpretations. In the second chapter, Sextus' claims about ordinary life are examined and it is argued that Sextus regards skepticism as a distinctive expression of ordinary life. However, ordinary life may be understood in two different ways and the failure to distinguish them has resulted in a misconception of Sextus' outlook. The two different conceptions are therefore elaborated and it is argued that Sextus' understanding of ordinary life accords with only one of them. Finally, responses are provided to some important objections to the close connection between iii skepticism and ordinary life. In the third and final chapter, Sextus' conception of ordinary life is deployed to produce a novel understanding of skeptical assent. The focus here is Sextus' account of assent in Outlines of Pyrrhonism 1.13. Each of the key concepts in that account are explained in light of chapter two's results. Additionally, the roots of a concept central to skeptical assent are located in Aristotle's methodological reflections. Finally, the novel account of skeptical assent is distinguished from two other closely related accounts.. iv. (shrink)

By means of the Ten Modes, Pyrrhonian skeptics appeal to conflicting appearances to bring about suspension of judgment. However, precisely how the skeptic might do so in a nondogmatic manner is not entirely clear. In this paper, I argue that existing accounts of the Modes face significant objections, and I defend an alternative account that better explains the logical structure, rational nature, and effectiveness of the Modes. In particular, I clarify how the Modes appeal to concerns about epistemic impartiality (...) and circularity, the nature of the skeptic's nondoxastic attitude(s), and how the skeptic can employ the Modes nondogmatically.

Review of Bett, R. (2019). How to Be a Pyrrhonist: The Practice and Significance of Pyrrhonian Skepticism. Cambridge: Cambridge UP.

An objection that has been raised to the conciliatory stance on the epistemic significance of peer disagreement known as the Equal Weight View is that it is self-defeating, self-undermining, or self-refuting. The proponent of that view claims that equal weight should be given to all the parties to a peer dispute. Hence, if one of his epistemic peers defends the opposite view, he is required to give equal weight to the two rival views, thereby undermining his confidence in the correctness (...) of the Equal Weight View. It seems that the same objection could be leveled against those who claim to suspend judgment in the face of pervasive unresolvable disagreements, as do the Pyrrhonian skeptics. In this paper, I explore the kind of response to the objection that could be offered from a neo-Pyrrhonian perspective, with the aim of better understanding the intriguing character of Pyrrhonian skepticism.

Disjunctivism is the view that perceptual experience is either constituted by fact in the world or mere appearance. This view is said to be able to guarantee our cognitive contact with the world, and thus remove a crucial “prop” upon which skepticism depends. This paper has two aims. First, it aims to show that disjunctivism is a solution to Cartesian skepticism. Cartesian skepticism is an epistemological thesis, not an ontological one. Therefore, if there is an external world, (...) we may well undergo a veridical experience, and thus we can take advantage of disjunctivism to adopt an anti-evidential-skepticism strategy to counter Cartesian skepticism. Second, this paper argues that disjunctivism fails to solve Pyrrhonian skepticism. To counter Pyrrhonian skepticism, one has to give reasons both for his belief and for his believing. But disjunctivism can only account the former, that is, the reason for the content of perceptual belief. Given that one’s experience in good case and bad case is subjectively indistinguishable, one cannot just use his experience to justify his believing. This shows that disjunctivism cannot meet the requirement to provide an adequate account for reflective knowledge. (shrink)

ABSTRACT Friedrich Nietzsche offers different opinions of the ancient Skeptics. On certain occasions, he praises them as philosophers of intellectual integrity, because they constantly question dogma and continue to inquire (ζητϵῖν) into the truth. He insists, however, that it is indispensable for every individual to adopt her own perspective in specific conditions, rather than suspend judgment as the Skeptics do. On other occasions, Nietzsche criticizes the ancient Skeptics because they separate their academic investigations from their philosophy of life and only (...) comply with conventions or apparent phenomena observed through sensations. Furthermore, he ridicules their ultimate goal – tranquility of mind (ἀταραξία) – as a product of feeble exhaustion. He himself is ready to embrace torments of life as part of the will to power. Although some similarities can be traced between Nietzsche and the ancient Skeptics, Nietzsche is more consistent in connecting his theoretical investigation and his philosophy as a way of life.

Early on in the Outlines of Pyrrhonism (PH), Sextus Empiricus offers an account of τὸ τέλος τῆς σκεπτικῆς—the aim or final end of Pyrrhonian skepticism. Having previously explained such crucial aspects of Pyrrhonism as the sense in which Skeptics do not hold any beliefs and what its constitutive principles are, in sections I 25-30 Sextus turns to what he seems to regard as the equally important matter of what the aim of Skepticism is. He tells us, An (...) aim [τέλος] is that for the sake of which everything is done or considered, while it is not done or considered for the sake of anything else. Or: an aim is the final object of desire. Up to now we say the aim of the Skeptic is tranquility [ἀταραξία] in matters of opinion and moderation of feeling [μετριοπάθεια] in matters forced on us. (PH I.25)2 In the sense of ‘ethics’ relevant to the Ancients, this constitutes Sextus’ major pronouncement on ethics in the general survey of Skepticism contained in PH I, apart from the specific arguments of the Tenth Mode (PH I 145-163). It is perhaps unsurprising that Sextus’ ethics, the heart of which is evident even in the.. (shrink)

Though ancient Pyrrhonian skepticism is apparently based on disagreement, this aspect of skepticism has been widely neglected in contemporary discussion on skepticism. The paper provides a rational reconstruction of the skeptical argument from disagreement that can be found in the books of Sextus Empiricus. It is argued that this argument forms a genuine skeptical paradox that has no fully satisfactory resolution. All attempts to resolve it make knowledge or justified belief either intuitively too easy or impossible.

In lieu of an abstract, here is a brief excerpt of the content:The Pyrrhonian Revival in Montaigne and NietzscheJessica N. BerryMichel de Montaigne occupies a unique place in Nietzsche's history of ideas. He is one of a very few figures for whom Nietzsche expresses deep admiration and about whom he has virtually nothing critical to say. This is a rare enough mark of distinction; but contrary to what it might lead us to expect, the relationship between Montaigne and Nietzsche (...) has seldom been carefully examined. There has yet to be a book-length study devoted solely to Montaigne and Nietzsche,1 and article-length treatments of the relationship between their works and thought have been surprisingly scarce. What discussions there have been tend to locate the connections between Nietzsche and Montaigne mainly in matters of either literary or personal style,2 but studies that examine Montaigne's influence on Nietzsche with an eye toward philosophical rather than literary or stylistic issues have been almost non-existent.3 This dearth of treatments can be explained, at least in part, by the fact that, while Montaigne is rightly recognized for the literary merits of his work and for its subsequent influence on later prose stylists (and not only in French), his work on the whole has seldom been appreciated as having any philosophical value in its own right. Small wonder, then, that the connection between Montaigne and Nietzsche has [End Page 497] appeared more significant to commentators on Montaigne who are interested in tracing his influence on later thinkers than to scholars of Nietzsche—even those Nietzsche scholars who take an acute interest in his intellectual heritage. What I will argue here is that Montaigne makes a more concrete and philosophically more substantive contribution to Nietzsche's thought than has generally been appreciated; specifically, by giving impetus to the naturalism that develops in Human, All Too Human as an antidote to Schopenhauer's pessimistic metaphysics of will.In this essay, I present a two-fold thesis about Montaigne's influence on Nietzsche's early work. First, I will argue that the "naturalistic turn" in Human, All Too Human reflects Nietzsche's engagement with Montaigne during a crucial moment in the development of his thought. Second, I will demonstrate that the naturalism Nietzsche adopts from Montaigne has roots in the tradition of Pyrrhonian skepticism that Montaigne carries forward into the Renaissance. In the end, a better understanding of the skeptical ancestry of Nietzsche's naturalism should help us make better sense of Human, All Too Human and its immediate successors in Nietzsche's oeuvre, which cultivate what otherwise seems to be an uneasy partnership between naturalism and skepticism.I. It is by now widely accepted that Nietzsche's estimation of the value of the techniques and methods of the natural sciences undergoes radical revision in the period culminating in the first volume of Human, All Too Human (HAH),4 a book sometimes described as inaugurating a "positivist" phase in Nietzsche's work. From the first of its nine major sections, "Of First and Last Things," HAH narrates a struggle between science on the one hand and philosophy on the other. It is important to note the breadth of the extension of the term "science" (Wissenschaft), which includes not only what we think of as the "hard" or physical sciences (physics, chemistry, and the like) but also areas of inquiry we now consider "behavioral sciences" such as psychology and sociology—and, Nietzsche would say, philology as well. "Philosophy," by contrast is specified more narrowly. As Nietzsche uses the term throughout HAH, "philosophy" is usually shorthand for "metaphysical philosophy" and singles out for criticism the discourse of metaphysics that has dominated the philosophical landscape at least since Plato.In the sense in which Nietzsche worries about it "metaphysical philosophy" promotes speculation about such supra-sensible entities as Platonic forms, Descartes's "immaterial substances," and Kantian things-in-themselves. That its contributions include, for instance, theories about the existence and immortality of the soul accounts for Nietzsche's grouping "metaphysical philosophy" [End Page 498] together with religion and art as "arts of narcosis."5 Consciously or not they endeavor to comfort us by assuaging our fear of death, our existential anxieties about the purposelessness of...

This work, written from a neo-Pyrrhonian perspective, is an examination of contemporary theories of knowledge and justification. It takes ideas primarily found in Sextus Empiricus's Outlines of Pyrrhonism, restates them in a modern idiom, and then asks whether any contemporary theory of knowledge meets the challenges they raise. The first part, entitled "Gettier and the Problem of Knowledge," attempts to rescue our ordinary concept of knowledge from those philosophers who have assigned burdens to it that it cannot bear. Properly (...) understood, Fogelin shows that the concept of knowledge is unproblematic. The second part of this study, called "Agrippa and the Problem of Justification," examines Agrippa's contribution to Pyrrhonism, a systematic reduction of its procedures which came to be known as the "Five Modes Leading to the Suspension of Belief." These modes present a completely general procedure for refuting any claim a dogmatist might make. Though largely unnoticed, there is, according to Fogelin, an uncanny resemblance between problems posed by Agrippa's "Five Modes" and those that contemporary epistemologists address under the heading of a theory of justification. Fogelin examines the strongest contemporary theories of justification--in both foundationalist and anti-foundationalist forms. The conclusion is that recent philosophical writings on justification have made no significant progress in responding to the Pyrrhonian problems these writings have addressed. (shrink)

It has become almost a conventional wisdom to argue that Cartesian scepticism poses a far more radical sceptical threat than its classical Pyrrhonian counterpart. Such a view fails to recognise, however, that there is a species of sceptical concern that can only plausibly be regarded as captured by the Pyrrhonian strategy. For whereas Cartesian scepticism is closely tied to the contentious doctrine of epistemological internalism, it is far from obvious that Pyrrhonian scepticism bears any such theoretical commitments. (...) It is argued here that by viewing the Pyrrhonian style of sceptical argument in terms of this contemporary epistemological externalist/internalist distinction one can gain a new insight into some of the more problematic elements of this variety of classical thought and also get a handle on certai contemporary worries that have been raised regarding the anti-sceptical efficacy of externalist theories of knowledge.

The Pyrrhonian skeptic’s stance, as described by Sextus Empiricus, is in good part defined by his suspending judgment or belief about all the matters he has so far investigated. Most interpreters of Pyrrhonism maintain that it is a mistake to understand this form of skepticism in terms of doubt because suspension as conceived of by the Pyrrhonist is markedly different from the state of doubt. In this article, I expound the reasons that have been offered in support of (...) that prevailing view and assess their strength. (shrink)

Peter Fosl presents an engaging and historically rich account of Hume's skepticism. For those readers interested in deepening their knowledge and understanding of Pyrrhonian and Academic skepticism, both in regard to their origins and their legacy, I highly recommend it. But I also recommend it for those who would like to better understand Hume's skepticism, although I do think there is some tension in Fosl's reading. Before I discuss this tension, a brief summary of the book (...) is in order. Fosl's primary claim is that Hume's skepticism is a hybrid of Academic and Pyrrhonian skepticism. To show this, Fosl divides the book into two parts. In the first, Fosl presents a detailed account of the ancient and modern versions... (shrink)

Markus Lammenranta’s essay sheds light on at least one of the reasons for this. Arguing that disagreement plays a key role not only in the Pyrrhonian but also in the Cartesian skeptical arguments, he contends that these arguments are intuitively sound and that their intuitiveness cannot be accounted for unless we assume a dialectical conception of justification. As we saw, this view maintains that one is justified in holding a belief if and only if, when appropriately challenged, one is (...) able to defend it by offering reasons for it. Lammenranta claims that such a conception of justification should be accepted because it is rooted in our ordinary epistemic practices, and that most epistemologists fail to appreciate and explain the strength of disagreement-based skeptical arguments because of their adoption of an individualistic and nondialectical epistemology.

This book puts forward a much-needed reappraisal of Immanuel Kant's conception of and response to skepticism, as set forth principally in the Critique of Pure Reason. It is widely recognized that Kant's theoretical philosophy aims to answer skepticism and reform metaphysics--Michael Forster makes the controversial argument that those aims are closely linked. He distinguishes among three types of skepticism: "veil of perception" skepticism, which concerns the external world; Humean skepticism, which concerns the existence of a (...) priori concepts and synthetic a priori knowledge; and Pyrrhonian skepticism, which concerns the equal balance of opposing arguments. Forster overturns conventional views by showing how the first of these types was of little importance for Kant, but how the second and third held very special importance for him, namely because of their bearing on the fate of metaphysics. He argues that Kant undertook his reform of metaphysics primarily in order to render it defensible against these types of skepticism. Finally, in a critical appraisal of Kant's project, Forster argues that, despite its strengths, it ultimately fails, for reasons that carry interesting broader philosophical lessons. These reasons include inadequate self-reflection and an underestimation of the resources of Pyrrhonian skepticism. (shrink)

In recent years, interpreters of the fourth century BCE Chinese Daoist text, the Zhuangzi, have increasingly appropriated the term, 'skepticism' as a label for the philosophical contribution of that text to classical Chinese philosophy. Despite their terminological agreement, these authors differ significantly in what they take to be the substance of this philosophical term, especially in its context as an interpretive device for understanding the Zhuangzi. This dissertation aims to understand the philosophy of the Zhuangzi by reference to the (...) Greek tradition of Pyrrhonian skepticism transmitted to the modern age by Sextus Empiricus. ;I illustrate the limitations of interpreting skepticism merely as negative dogmatism and illuminate the virtues of understanding it as the recommendation of a philosophical attitude of non-assertion and open-mindedness. Robert E. Allinson, Philip J. Ivanhoe, Bryan W. Van Norden, and Chad Hansen interpret skepticism as an anti-intellectual negative dogmatism, and I take issue with the appropriateness of such an interpretation. In so doing, I examine the work of A.C. Graham, Paul Kjellberg, and Lisa Raphals, who understand the skeptical sections of the Zhuangzi as recommendations for living a fulfilling life. These thinkers offer more coherent interpretations in so far as their readings construe Zhuangzi's skepticism as supporting rather than conflicting with the passages that advocate a variety of spiritual practices designed to bring about peace of mind and harmony. While these interpreters have drawn attention to the importance of Zhuangzi's spiritual and moral recommendations for living a productive life, my analysis, in suggesting that Zhuangzi moves from non-dogmatic or aporetic skepticism to way-making , develops this positive result of Zhuangzi's non-dogmatic skepticism further. This positive result is explored in connection with the extent to which non-dogmatic skepticism can serve as a foundation for the adoption of an attitude of philosophical pluralism, which suggests that there are a plurality of different standpoints, attitudes, approaches, perspectives, and 'positions' each of which may be valid in some sense and in some degree, and yet none of which is immune from criticism. I also address the criticism of aporetic skepticism that living a life without dogmatic commitments is impossible. (shrink)

Hegel’s Science of Logic is widely acknowledged as one of the greatest works of European philosophy. However, its contribution to arguably the most important philosophical problem, Pyrrhonian scepticism, has never been examined in any detail. Pyrrhonian Scepticism and Hegel's Theory of Judgement fills a great lacuna in Hegel scholarship by convincingly proving that the dialectic of the judgement in Hegel’s Science of Logic successfully refutes this kind of scepticism. Although Ioannis Trisokkas has written the book primarily for those (...) students of philosophy who already have an interest in Hegel’s epistemology and philosophy of language and/or his Science of Logic, it will also appeal to those who investigate the problem of scepticism independently of the Hegel corpus.

In this article, I tackle a heretofore unnoticed difficulty with the application of Pyrrhonian scepticism to science. Sceptics can suspend belief regarding a dogmatic proposition only by setting up opposing arguments for and against that proposition. Since Sextus provides arguments exclusively against particular geometrical definitions in Adversus Mathematicos III, commentators have argued that Sextus’ method is not scepticism, but negative dogmatism. However, commentators have overlooked the fact that arguments in favour of particular geometrical definitions were absent in ancient geometry, (...) and hence unavailable to Sextus. While this might explain why they are also absent from Sextus’ text, I survey and evaluate various strategies to supply arguments in support of particular geometrical definitions. (shrink)

In his Pyrrhonian Outlines , Sextus Empiricus employs an argument based upon the possibility of disagreement in order to show that one should not assent to a Dogmatic claim to which at present one cannot oppose a rival claim. The use of this argument seems to be at variance with the Pyrrhonian stance, both because it does not seem to accord with the definition of Skepticism and because the argument appears to entail that the search for truth (...) is doomed to failure. In the present paper, I examine the passages in which Sextus utilizes the argument from possible disagreement and offer an interpretation that makes the use of this argument compatible with the Pyrrhonian outlook.

Pyrrhonism was one of the two main ancient skeptical traditions. In this second paper of the three‐part series devoted to ancient skepticism, I present and discuss some of the issues on Pyrrhonian skepticism which have been the focus of much attention in the recent literature. The topics to be addressed concern the outlooks of Pyrrho, Aenesidemus, and Sextus Empiricus.

There are some tantalizing suggestions that Pyrrhonian skepticism has its roots in ancient India. Of them, the most important is Diogenes Laertius’s report that Pyrrho accompanied Alexander to India, where he was deeply impressed by the character of the “naked sophists” he encountered (DL IX 61). Influenced by these gymnosophists, Pyrrho is said to have adopted the practices of suspending judgment on matters of belief and cultivating an indifferent composure amid the vicissitudes of ordinary life. Such conduct, and (...) the attitudes that it embodied, became inspirations to later skeptical thinkers. It is a fact that practices of the sort attributed to Pyrrho are richly evident in a number of ancient Indian philosophical and ascetic movements. On this basis, attempts have been made to determine the identity of these gymnosophists and, further, to pinpoint the dialectical tropes within Pyrrhonism that may have their basis in Indian thought. But despite these attempts, and in the absence of any new discoveries, these suggestions will likely remain just that. The paucity of the historical data and the problematic nature of the data itself prevent us from reconstructing a solid bridge between ancient India and Greek skepticism that may serve as the basis of robust historical theorizing. Classical India does, however, lay claim to a sophisticated and diverse culture of epistemological reflection, which includes a number of innovative skeptical thinkers deserving study on their own merits. This chapter is meant to provide such a study, or perhaps more accurately, a prolegomena for such. After some initial ground-laying, I will discuss three leading Indian skeptics and situate them historically and conceptually within the network of competing schools that comprise classical Indian philosophy. They are Nāgārjuna (c. 150 CE), the founder of Madhyamaka Buddhism, Jayarāśi (c. 800), associated with the Indian materialist tradition, and Śrīharṣa (c. 1150), a thinker connected to the school of Nondual (Advaita) Vedānta.

In his defense of a coherence theory of truth and knowledge, Donald Davidson insists that (i) we must take the objects of a belief to be the causes of that belief, and (ii) given the nature of beliefs, most of our be-liefs are veridical. As result, a response to skepticism is provided. If most of our beliefs turn out to be true, global skepticism is ultimately incoher-ent. In this paper, I argue that, despite the many attractions that a (...) co-herence theory has, a response to skepticism is not among them. After distinguishing three forms of skepticism (global skepticism, Pyrrhonian skepticism and lottery skepticism), I argue that none of them is affected by Davidson’s strategy. (shrink)

This is a defense of Pyrrhonian skepticism against the charge that the suspension of judgment based on equipollence is vitiated by the assent given to the equipollence in question. The apparent conflict has a conceptual side as well as a practical side, examined here as separate challenges with a section devoted to each. The conceptual challenge is that the skeptical transition from an equipollence of arguments to a suspension of judgment is undermined either by a logical contradiction or (...) by an epistemic inconsistency, perhaps by both, because the determination and affirmation of equipollence is itself a judgment of sorts, one that is not suspended. The practical challenge is that, independently of any conceptual confusion or contradiction, suspending judgment in reaction to equipollence evinces doxastic commitment to equipollence, if only because human beings are not capable of making assessments requiring rational determination without believing the corresponding premises and conclusions to be true. The two analytic sections addressing these challenges are preceded by two prefatory sections, one laying out the epistemic process, the other reviewing the evidentiary context. The response from the conceptual perspective is that the suspension of judgment based on equipollence is not a reasoned conclusion adopted as the truth of the matter but a natural reaction to an impression left by the apparently equal weight of opposing arguments. The response from the practical perspective is that the acknowledgment of equipollence is not just an affirmation of the equal weight of arguments but also an admission of inability to decide, suggesting that any assent, express or implied, is thrust upon the Pyrrhonist in a state of epistemic paralysis affecting the will and the intellect on the matter being investigated. This just leaves a deep disagreement, if any, regarding whether equipollence is an inference based on discursive activity or an impression coming from passive receptivity. But this, even if resolved in favor of the critic (which it need not and ought not be), is not the same as confusion or inconsistency on the part of the Pyrrhonist, the demonstration of which is the primary aim of this paper.
