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.

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.

How is it possible for David Hume to be both withering skeptic and constructive theorist? I recommend an answer like the Pyrrhonian answer to the question how it is possible to suspend all judgment yet engage in active daily life. Sextus Empiricus distinguishes two kinds of assent: one suspended across the board and one involved with daily living. The first is an act of will based on appreciation of reasons; the second is a causal effect of appearances. Hume makes (...) the same distinction, only he extends the sort of assent involved in daily life to theoretical matters as well. He is a skeptic both in finding no reason to grant the first sort of assent and in being subject to the second. (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 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.

This chapter focuses on the responses that proponents of virtue epistemology (VE) make to radical skepticism and particularly to two related forms of it, Pyrrhonian skepticism and the “underdetermination-based” argument, both of which have been receiving widening attention in recent debate. Section 1 of the chapter briefly articulates these two skeptical arguments and their interrelationship, while section 2 explains the close connection between a virtue-theoretic and a neo-Moorean response to them. In sections 3 and 4 I advance (...) arguments for improving the prospects of virtue-theoretic responses, sketching a particular version of VE that by recasting somewhat how we understand the “externalist turn in epistemology” also suggests ways of improving the adequacy of philosophical diagnoses and responses to skepticism.

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)

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.

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.

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.

This paper argues that Sextus Empiricus’s Pyrrhonism is a form of relativism markedly different from the positions typically referred to by this term. The scholars who have explored the relativistic elements found in Sextus’s texts have claimed that his outlook is not actually a form of relativism, or that those elements are inconsistent with his account of Pyrrhonism, or that he is confusing skepticism with relativism. The reason for these views is twofold: first, when employing the term ‘relativism’ one (...) hardly has in mind the sort of relativist stance adopted by the Pyrrhonist; and second, those scholars have misinterpreted Sextus’s relativistic remarks. The purpose of this paper is to show that he adopts a ‘phenomenological’ kind of relativism that is compatible with his account of Pyrrhonism. (shrink)

This paper approaches the current epistemological debate on peer disagreement from a neo-Pyrrhonian perspective, thus adopting a form of skepticism which is more radical than those discussed in the literature. It makes use of argumentative strategies found in ancient Pyrrhonism both to show that such a debate rests on problematic assumptions and to block some maneuvers intended to offer an efficacious way of settling a considerable number of peer disputes. The essay takes issue with three views held in (...) the peer disagreement debate: there is an objective fact of the matter about at least most controversial questions; we possess theory-neutral evidence bearing on those questions which grants us access to the truth of the matter; and many peer controversies are resolved by attending to which disputant has correctly evaluated the objective evidence. With respect to the first two views, it is argued that the belief in both objective facts and theory-neutral evidence is subject to fierce dispute, and should not therefore be taken for granted in the discussion of peer disagreement. As for the third view, it is argued that from either a first- or a third-person perspective, there seems to be epistemic symmetry between the disputants which makes it necessary to suspend judgment.

In this chapter I sympathetically consider the idea that skepticism is an epistemic virtue. I argue that this depends on whether skepticism is admirable, and articulate three defenses of skepticism as admirable: a Pyrrhonian defense (on which skepticism leads to tranquility), a Cartesian defense (on which skepticism is prophylactic against error), and a liberal defense (on which skepticism counteracts dogmatism and closed-mindedness). I give the liberal defense the most attention: I distinguish skepticism (...) from several species of dogmatism that are sometimes called “skeptical” (e.g. that of “climate change skeptics”), and associate skepticism with political moderation and intellectual independence. (shrink)

Ancient philosophy knew two main skeptical traditions: the Pyrrhonian and the Academic. In this final paper of the three‐part series devoted to ancient skepticism, I present some of the topics about Academic skepticism which have recently been much debated in the specialist literature. I will be concerned with the outlooks of Arcesilaus, Carneades, and Philo of Larissa.

I offer a novel reading in this dissertation of René Descartes’s (1596–1650) skepticism in his work Meditations on First Philosophy (1641–1642). I specifically aim to answer the following problem: How is Descartes’s skepticism to be read in accordance with the rest of his philosophy? This problem can be divided into two more general questions in Descartes scholarship: How is skepticism utilized in the Meditations, and what are its intentions and relation to the preceding philosophical tradition? -/- I (...) approach the topic from both a historical and a text-based analysis, combining textual and contextual research. I examine Descartes’s skepticism against two main traditions in the historical analysis: philosophical skepticism and Aristotelian Scholasticism. I argue that skepticism in the Meditations is intended to oppose and upheave both Scholasticism and skepticism. The intended results of the work are not merely epistemological but also metaphysical and even ethical. Furthermore, these ambitions cannot be neatly distinguished but merge into each other. -/- The third historical context against which the skeptical meditations are examined is the literary genre of meditative exercises, particularly from the 1500–1600’s, which, while religiously and spiritually oriented, likewise provided the practitioner with an enlightened understanding of self-knowledge and their cognitive place in the world on the way to closer spiritual proximity to God. I argue by this reading that the skepticism of the Meditations is an attentive, meditational cognitive exercise that is not merely instrumental and methodological but is to have a genuine and serious (psychologically real) effect on our thinking. The skeptical meditation is not simply a theoretical thought experiment but is to be seriously practiced as a transformative process of reorienting one’s cognitive framework to discover truth, certainty, and a way to a happy, tranquil, and virtuous life. -/- I offer a close reading in the textual analysis of the first three meditations of the Meditations. I argue that the meditative skepticism employed in the work does not reject the previous beliefs but suspends judgment on them, withdrawing assent until further evidence can be found. I introduce a new term into Descartes scholarship in this analysis, based on the terminology of ancient skepticism: Cartesian epochē (gr. epochē, suspension, withdrawal). Instead of rejecting previous beliefs or assenting to the probably false, the skeptical procedure of the Meditations is argued to emulate in important ways the suspension of judgment on equally balanced reasons in ancient Pyrrhonian skepticism. Novel interpretations are presented along the way of the will’s freedom, of the First Meditation’s skeptical scenarios, of the cogito, and of the vindication of metaphysical certainty, as well as a clarification of the Cartesian Circle problem. -/- Reinterpreting the relation of Descartes’s skepticism to the preceding historical and literary traditions leads to a new look at the skeptical method itself. Presenting a new interpretation of skepticism in the Meditations leads at the same time to a new look at its relation to the historical context. The two research questions are, then, intrinsically tied together. -/- My focus in the study is on the Meditations, but I also reference and discuss Descartes’s other philosophical works, as well as his correspondence, when necessary.

Julia Annas has affirmed that the kind of modern moral skepticism which denies the existence of objective moral values rests upon a contrast between morality and some other system of beliefs about the world which is not called into doubt. Richard Bett, on the other hand, has argued that the existence of such a contrast is not a necessary condition for espousing that kind of moral skepticism. My purpose in this paper is to show that Bett fails to (...) make a good case against Annas’ thesis. To accomplish this, it will be helpful to consider the Pyrrhonean attitude towards morality as expounded in Sextus Empiricus’ work. (shrink)

In the article of Bueno titled “Davidson and Skepticism: How Not to Respond to the Skeptic,” he intends to demonstrate that although Davidson’s theory of Coherence holds many attractions, it does not entail a response to any kinds of skepticism including Global, Lottery, and Pyrrhonian. In this study, the goal is to criticize the work of Prof. Bueno in connection with two criticisms raised by him over Davidson’s anti-skeptical strategy. Further, by giving some reasons in favor of (...) Davidson’s anti-skepticism argument, it will be shown that neither the above stated criticisms nor the global skepticism response could undermine the validity of anti-skepticism argument. (shrink)

Peter Fosl's new monograph offers a bold reading of Hume as a "radical," "coherent," and "hybrid" skeptic, who draws influence from both the Pyrrhonian and Academic skeptical traditions. I press some concerns about whether Fosl's reading of Hume can accommodate his scientific ambitions.

There is a set of texts in the history of ancient skepticism that have not been widely understood. Michael Frede has done much to set these texts in their proper context, but his work has not gotten the appreciation it deserves. Historians have tended to think that ancient skepticism in the Clitomachian-Pyrrhonian tradition is the suspension of belief on all matters and that Frede’s attempt to show otherwise is confused. This may turn out to be correct, but (...) Frede’s interpretation, as I think it should be understood, is more plausible and interesting than is usually thought. Frede has made it possible to see the skeptics in the Clitomachian-Pyrrhonian tradition as taking some of the first steps in working out the philosophical view that epistemic justification is a matter of whether a belief is the sustained outcome of a correct cognitive process and that correctness here need not and perhaps should not be understood in terms of modal reliability.

It is standardly believed that the only way to justify an assertion in the face of a challenge is by making another assertion. Call this claim ASSERTIONS ONLY. Besides its intrinsic interest, ASSERTIONS ONLY is relevant to deciding between competing views of the norms that govern reasoned discourse. ASSERTIONS ONLY is also a crucial part of the motivation for infinitism and Pyrrhonian skepticism. I suggest that ASSERTIONS ONLY is false: I can justify an assertion by drawing attention to (...) something that clearly makes the assertion true, or likely true. (shrink)

Several philosophers have recently advanced wager-based arguments for the existence of irreducibly normative truths or against normative nihilism. Here I consider whether these wager-based arguments would cause a normative Pyrrhonian skeptic to lose her skepticism. I conclude they would not do so directly. However, if prompted to consider a different decision problem, which I call the normativity wager for skeptics, the normative Pyrrhonian skeptic would be motivated to attempt to act in accordance with any normative reasons to (...) which she might be subject. Consideration of the normativity wager will not inevitably cause the normative Pyrrhonian skeptic to lose her skepticism, but there are at least three routes by which it might: first, in considering the wager the agent may spontaneously (non-rationally) acquire a normative belief; second, considering the wager can motivate the agent to cause herself to (non-rationally) acquire a normative belief. Via either of these indirect, non-rational routes, she would cease to be a normative Pyrrhonian skeptic. Thus, consideration of the normativity wager may have value, even if it does not supply a rational argument that will dissuade skeptics. In addition, I consider the possibility of a third (rational) route by which the agent might lose her skepticism. (shrink)

It is generally thought that suspension of judgment about a proposition p is the doxastic attitude one is rationally compelled to adopt whenever the epistemic reasons for and against p are equipollent or equally credible, that is, whenever the total body of available evidence bearing on p epistemically justifies neither belief nor disbelief in p. However, in a recent contribution to this journal, Jan Wieland proposes “to broaden the conditions for suspension, and argue that it is rational to suspend belief (...) on a certain issue even if one’s current evidence is not neutral (or even close to neutral)”. My aim in this paper is to point to a number of problems in Wieland’s position, some of which in connection with the account of Pyrrhonian skepticism found in the extant works of Sextus Empiricus.

My purpose in this paper is to examine whether Pyrrhonian skepticism, as this stance is described in Sextus Empiricus’s extant works, has practical or epistemic value. More precisely, I would like to consider whether the Pyrrhonist’s suspension of judgment (ἐποχή) and undisturbedness (ἀταραξία) can be deemed to be of practical or epistemic value. By ‘practical’ value I mean both moral value and prudential value. Moral value refers to moral rightness and wrongness; prudential value to the value of well-being, (...) personal or social. Hence, when I ask whether the Pyrrhonist’s suspension and undisturbedness have practical value, I mean whether they make us behave in a manner that is morally right or wrong, and whether they allow us to attain those goals that would make it possible to live well. As for ‘epistemic’ value, it refers basically to the values of attaining truth and avoiding error. Hence, when I ask whether the Pyrrhonist’s suspension has epistemic value, I mean whether it allows us to attain truth and avoid error. My main focus will be the practical value of both suspension and undisturbedness because this is the value on which ancient philosophy scholars critical of Pyrrhonism have laid emphasis. The reason for examining the epistemic value of suspension is that doing so will enable a fuller assessment of the significance of Pyrrhonism as a kind of philosophy, which is my primary concern.

The Knowledge Norm of Assertion claims that it is proper to assert that p only if one knows that p. Though supported by a wide range of evidence, it appears to generate incorrect verdicts when applied to utterances of “I don't know.” Instead of being an objection to KNA, I argue that this linguistic data shows that “I don't know” does not standardly function as a literal assertion about one's epistemic status; rather, it is an indirect speech act that has (...) the primary illocutionary force of opting out of the speaker's conversational responsibilities. This explanation both reveals that the opt-out is an under-appreciated type of illocutionary act with a wide range of applications, and shows that the initial data in fact supports KNA over its rivals.

By understanding the sense in which Sextus thinks reason is deceptive we may clarify his attitude towards ordinary life. The deception, like that of the Siren's song, is practical rather than epistemic. It is not a matter of leading us to assent to false or unjustified conclusions but is rather a distraction from, or even corruption of, ordinary life.

In her book Michel de Montaigne: Accidental Philosopher, Ann Hartle argues that Montaigne’s thought is dialectical in the Hegelian sense. Unlike Hegel’s progressive dialectic, however, Montaigne’s thought is, according to Hartle, circular in that the reconciliation of opposed terms comes not in the form of a newly emergent term, but in a return to the first term, where the meaning of the first is transformed as a result of its dialectical interaction with the second. This analysis motivates Hartle’s claim that (...) Montaigne is not a skeptic at all, let alone a Pyrrhonian skeptic. In this paper, I argue that Hartle’s circular-dialectical interpretation of Montaigne is not only compatible with Pyrrhonism, but is in fact an ideal model for understanding Sextus Empiricus’s skeptical therapy.

Hume's Treatise arguments concerning space, time, and geometry, especially ones involving his denial of infinite divisibility; have suffered harsh criticism. I show that in the section "Of the ideas of space and time," Hume gives important characterizations of his skeptical approach, in some respects Pyrrhonian, that will be developed in the rest of the Treatise. When that approach is better understood, the force of Hume's arguments can be appreciated, and the influential criticisms of them can be seen to miss (...) the mark. (shrink)

The first article of the cycle “The role of skeptical evidence in the First and Second ‘Meditations’” compares the Cartesian and Sextus Empiricus’ concepts of doubt in, respectively, “Metaphysical meditations” and “Outlines of Pyrrhonism”. The article starts with the current state of the problem “Descartes and skepticism” and admits the existence of consensus about Cartesian perception of skeptical tradition: Cartesius (1) was influenced by all skeptical movements, known in his time, and (2) created a generalized notion that contains elements (...) of both Academic and Pyrrhonian origin. This consensus is the source of many contemporary studies on how different skeptical doctrines influenced certain parts of Cartesian philosophy. This article attempts to analyze possible Descartes’ use of Sextus Empiricus’ notion of phenomenon. Sextus clearly states in “Outlines of Pyrrhonism” that one cannot doubt phenomenon as something perceived directly. The article proves that (a) Sextus’ thesis about the “sensory” nature of phenomenon is metaphorical, so far as it includes (without distinction) both sensuality and the experience of thinking; (b) the phenomenon is realized through a wide range of passive states of mind that all have irresistible force of influence; (c) the impact of phenomena is always mediated by our self, because all skeptical phrases are strictly correlated with the first person singular. Some researchers distinguish Sextus’ isostenia, as one of such insurmountable states, from Cartesian doubt at the First Meditation, which is allegedly based on a purely volitional decision. The article proved that this argument is artificial, since Descartes’ volitional decision is caused by initial inability to take the dubious as if it were certain. Thus, Cartesian approach can be considered a specific kind of isostenia. Such parallelism is a reason to assume a key role of Sextus’ understanding of insurmountable power of phenomena in Cartesian anti-sceptical argumentation. This assumption will be tested in the following articles of the cycle. (shrink)

Despite its central role in his important theories of self and external world, Hume’s account of numerical identity has been neglected or misunderstood. The account is designed as a response to a difficulty concerning identity apparently original with Hume. I argue that the problem is real, crucial, and remains unresolved today. Hume’s response to the difficulty enlists his idiosyncratic, empiricist views on time: time consists of discrete, partless moments, some of which coexist with successions of others. Time is more like (...) a wall of variously sized bricks than like a continuous line. Hume’s arguments that time (and space) are not infinitely divisible have met with literal contempt. I show that his unusual views are motivated and consistent. The topic of identity leads naturally to Hume’s account of personal identity and his later retraction--one of the most widely discussed topics in Hume scholarship. I give a new, straightforward explanation of the retraction, by arguing that Hume’s views on consciousness preclude his prior account of the self as a fiction. I then suggest that Hume’s fundamental problem for personal identity is his general difficulty concerning identity. Discussing Hume’s metaphysics raises perhaps the most central and difficult topic in Hume scholarship--how to reconcile the constructive, theoretical Hume with the skeptical Hume. The prevailing view for the last century has been that Hume’s skepticism is limited, leaving room for his theorizing. I argue, rather, that Hume is an unlimited Pyrrhonian skeptic in relevant respects, and that this interpretation of him best reconciles his two sides. (shrink)

Justin Garson introduces the distinction between two views on Madness we encounter again and again throughout history: Madness as dysfunction, and Madness as strategy. On the latter view, Madness serves some purpose for the person experiencing it, even if it’s simultaneously harmful. The strategy view makes intelligible why Madness often holds a certain allure – even when it’s prima facie terrifying. Moreover, if Madness is a strategy in Garson’s metaphorical sense – if it serves a purpose – it makes sense (...) to use consciously chosen strategies for living with Madness that doesn’t necessarily aim to annihilate or repress it as far as possible. In this paper, we use our own respective stories as case studies. We have both struggled to resist the allure of Madness, and both ended up embracing a kind of Pyrrhonian scepticism about reality instead of clinging to sane reality. (shrink)

Philosophical counselling is generally understood as the discussion or resolution of everyday problems with the help of philosophy. However, few agree on this definition. This leads to a crisis of definition for philosophical counselling which in turn causes practical problems regarding, inter alia, the teaching of future philosophical counsellors, the question of method, and the potential scope of philosophical counselling. I identify in this study a prevalent therapeutic thesis on the nature of philosophical counselling which ties together some of the (...) more popular conceptions of philosophical counselling. This thesis predominates when philosophical counsellors focus on the counselling part and neglect the philosophical part of philosophical counselling. This stance keeps philosophical counselling firmly contained within a medico-therapeutic framework. In opposition to this predominant view, I propose a reconceptualisation of philosophical counselling which does not subscribe to the therapeutic thesis and by implication works outside of a medical framework. More specifically, in fleshing out my non-therapeutic understanding of philosophical counselling, I propose twelve context-dependent conditions of philosophical counselling by drawing on a Pyrrhonian disposition and also on examples of philosophical counsellors who begin to work outside of the medico-therapeutic framework. I argue that these conditions should be met for philosophical counselling to stay firmly within the realm of philosophy as an aim in itself, thereby remaining true to its origin and basic orientation, and drawing on its innate strengths. With this fundamental reconceptualisation and the accompanying twelve context-dependent conditions, I propose a novel account of philosophical counselling which (i) does not subscribe to the therapeutic thesis, (ii) gives a novel answer to the problem of educating future philosophical counsellors, and (iii) has a clear scope of potential counselees.

The Pyrrhonist’s argumentative practice is characterized by at least four features. First, he makes a therapeutic use of arguments: he employs arguments that differ in their persuasiveness in order to cure his dogmatic patients of the distinct degrees of conceit and rashness that afflict them. Secondly, his arguments are for the most part dialectical: when offering an argument to oppose it to another argument advanced by a given dogmatist, he accepts in propria persona neither the truth of its premises and (...) conclusion nor the validity of its logical form. Thirdly, he avails himself of arguments in his own open-minded inquiry into the truth about a wide range of topics. Fourthly, Pyrrhonian argumentation is oppositional inasmuch as it typically works by producing oppositions among arguments that appear to the Pyrrhonist to be equipollent. In this article, I focus on the first three features with the aim of both shedding some light on them and determining whether they are in tension or coherently relate to each other. (shrink)

In this chapter, I present and explore various arguments for skepticism that are related to memory. My focus will be on the aspects of the arguments that are unique to memory, which are not shared, for example, by the more often explored skeptical arguments related to perception. -/- Here are some interesting upshots. First, a particular problem for justifiably concluding that one's memory is reliable is that any reasoning in favor of this conclusion will either result in epistemically circularity (...) or not be sufficient to justify the conclusion. Second, since many beliefs stored in memory do not appear to be based on evidence, it might also appear to follow that they are not justified. Third, although many stored memory beliefs are not based on stored memory experiences in the same way that perceptual beliefs are based on perceptual experiences, skeptical scenarios loom just as problematically for memory beliefs as they do for perceptual beliefs.

A common response to radical skeptical challenges to our knowledge of the external world has been that there are explanatory reasons (e.g., simplicity, coherence, explanatory power, conservatism) for favoring commonsense explanations of our sensory experiences over skeptical explanations. Despite the degree of visibility this class of response has enjoyed, it has often been viewed with skepticism [sic] by the epistemological community because of concerns about the epistemic merits of explanatory reasoning. I argue that skeptical challenges that employ skeptical hypotheses (...) presuppose central explanationist tenets and that this fact should raise one’s estimation of the strength of explanationist responses to skepticism.

Skepticism about the internal world is actually more troubling than skepticism about the external world.

Abstract Timothy Williamson has recently proposed to undermine modal skepticism by appealing to the reducibility of modal to counterfactual logic ( Reducibility ). Central to Williamson’s strategy is the claim that use of the same non-deductive mode of inference ( counterfactual development , or CD ) whereby we typically arrive at knowledge of counterfactuals suffices for arriving at knowledge of metaphysical necessity via Reducibility. Granting Reducibility, I ask whether the use of CD plays any essential role in a Reducibility-based (...) reply to two kinds of modal skepticism. I argue that its use is entirely dispensable, and that Reducibility makes available replies to modal skeptics which show certain propositions to be metaphysically necessary by deductive arguments from premises the modal skeptic accepts can be known.

The epistemological debate about radical skepticism has focused on whether our beliefs in apparently obvious claims, such as the claim that we have hands, amount to knowledge. Arguably, however, our concept of knowledge is only one of many knowledge-like concepts that there are. If this is correct, it follows that even if our beliefs satisfy our concept of knowledge, there are many other relevantly similar concepts that they fail to satisfy. And this might give us pause. After all, we (...) might wonder: What is so great about the concept of knowledge that we happen to have? Might it be more important, epistemically speaking, to investigate whether our beliefs satisfy some other relevantly similar concept instead? And how should questions such as these even be understood? This paper discusses the epistemological significance of these issues. In particular, a novel skeptical stance called ‘meta-skepticism’ is introduced, which is a kind of skepticism about the idea that some knowledge-like concepts are epistemically more important than others. It suggested that it is unclear whether this form of skepticism can be avoided. (shrink)

Counterfactual skepticism says that most ordinary counterfactuals are false. While few endorse counterfactual skepticism, the precise costs of the view are disputed and not generally well-understood. I have two aims in this paper. My first and primary aim is to establish, on grounds acceptable to all parties, that counterfactual skepticism is not benign. I argue it leads to significant skepticism about the future: if counterfactual skepticism is true, then we can have only very limited knowledge (...) about the future. I give three arguments to this conclusion, taking as premises principles connecting knowledge of indicative conditionals to knowledge of disjunctions; and principles linking knowledge of indicative conditionals to knowledge of counterfactual conditionals.My second aim is to examine the consequences for non-skeptical theories. My arguments indicate that not only are many ordinary counterfactuals true, but that we also know them. How can this be reconciled with the very real tension between counterfactuals and chance? I consider two solutions, one purely epistemic and one contextualist. Together they suggest something like contextualism about knowledge is required to fully resolve the skeptical threat. (shrink)

Empirical work on motivated reasoning suggests that our judgments are influenced to a surprising extent by our wants, desires and preferences (Kahan 2016; Lord, Ross, and Lepper 1979; Molden and Higgins 2012; Taber and Lodge 2006). How should we evaluate the epistemic status of beliefs formed through motivated reasoning? For example, are such beliefs epistemically justified? Are they candidates for knowledge? In liberal democracies, these questions are increasingly controversial as well as politically timely (Beebe et al. 2018; Lynch forthcoming, 2018; (...) Slothuus and de Vreese 2010). And yet, the epistemological significance of motivated reasoning has been almost entirely ignored by those working in mainstream epistemology. We aim to rectify this oversight. Using politically motivated reasoning as a case study, we show how motivated reasoning gives rise to three distinct kinds of skeptical challenges. We conclude by showing how the skeptical import of motivated reasoning has some important ramifications for how we should think about the demands of intellectual humility. (shrink)

There are many different oughts. There is a moral ought, a prudential ought, an epistemic ought, the legal ought, the ought of etiquette, and so on. These oughts can prescribe incompatible actions. What I morally ought to do may be different from what I self-interestedly ought to do. Philosophers have claimed that these conflicts are resolved by an authoritative ought, or by facts about what one ought to do simpliciter or all-things-considered. However, the only coherent notion of an ought simpliciter (...) has preposterous first-order normative commitments. It is more reasonable to reject the ought simpliciter in favor of the form of normative pluralism advocated in (Tiffany 2007). (shrink)

Skepticism is one of the most enduring and profound of philosophical problems. With its roots in Plato and the Sceptics to Descartes, Hume, Kant and Wittgenstein, skepticism presents a challenge that every philosopher must reckon with. In this outstanding collection philosophers engage with skepticism in five clear sections: the philosophical history of skepticism in Greek, Cartesian and Kantian thought; the nature and limits of certainty; the possibility of knowledge and related problems such as perception and the (...) debates between objective knowledge and constructivism; the transcendental method as a response to skepticism and the challenge of naturalism; overcoming the skeptical challenge.

This paper outlines a new type of skepticism that is both compatible with fallibilism and supported by work in psychology. In particular, I will argue that we often cannot properly trust our ability to rationally evaluate reasons, arguments, and evidence (a fundamental knowledge-seeking faculty). We humans are just too cognitively impaired to achieve even fallible knowledge, at least for many beliefs.

A new kind of skepticism about philosophy is articulated and argued for. The key premise is the claim that many of us are well aware that in the past we failed to have good responses to substantive objections to our philosophical beliefs. The conclusion is disjunctive: either we are irrational in sticking with our philosophical beliefs, or we commit some other epistemic sin in having those beliefs.

It has recently been argued that indeterminacy and indeterminism make most ordinary counterfactuals false. I argue that a plausible way to avoid such counterfactual skepticism is to postulate the existence of primitive modal facts that serve as truth-makers for counterfactual claims. Moreover, I defend a new theory of ‘might’ counterfactuals, and develop assertability and knowledge criteria to suit such unobservable ‘counterfacts’.

Keith DeRose’s solution to the skeptical problem is based on his indirect sensitivity account. Sensitivity is not a necessary condition for any kind of knowledge, as direct sensitivity accounts claim, but the insensitivity of our beliefs that the skeptical hypotheses are false explains why we tend to judge that we do not know them. The orthodox objection line against any kind of sensitivity account of knowledge is to present instances of insensitive beliefs that we still judge to constitute knowledge. This (...) objection line offers counter-examples against the claim of direct sensitivity accounts that sensitivity is necessary for any kind of knowledge. These examples raise an easy problem for indirect sensitivity accounts that claim that there is only a tendency to judge that insensitive beliefs do not constitute knowledge, which still applies to our beliefs that the skeptical hypotheses are false. However, a careful analysis reveals that some of our beliefs that the skeptical hypotheses are false are sensitive; nevertheless, we still judge that we do not know them. Therefore, the fact that some of our beliefs that the skeptical hypotheses are false are insensitive cannot explain why we tend to judge that we do not know them. Hence, indirect sensitivity accounts cannot fulfill their purpose of explaining our intuitions about skepticism. This is the hard problem for indirect sensitivity accounts. (shrink)
