Radical skepticism relies on the hypothesis that one could be completely cut off from the external world. In this paper, I argue that this hypothesis can be rationally motivated by means of a conceivability argument. Subsequently, I submit that this conceivability argument does not furnish a good reason to believe that one could be completely cut off from the external world. To this end, I show that we cannot adequately conceive scenarios that verify the radical skeptical hypothesis. (...) Attempts to do so fall prey to one or another of three pitfalls: they end up incomplete, reveal a deep contradiction or recreate a non-skeptical hypothesis. I use these results to improve upon Pritchard’s recent attempt at undercutting radical skepticism. (shrink)

The Neo-Moorean response to the radical skeptical challenge boldly maintains that we can know we’re not the victims of radical skeptical hypotheses; accordingly, our everyday knowledge that would otherwise be threatened by our inability to rule out such hypotheses stands unthreatened. Given the leverage such an approach has against the skeptic from the very start, the Neo-Moorean line is an especially popular one; as we shall see, though, it faces several commonly overlooked problems. An initial problem is that (...) this particular brand of anti-skeptical strategy is available only to a theory of knowledge that will compromise itself to especially weak epistemic standards—indeed, standards as weak as our epistemic grounds are for accepting the denials of skeptical hypotheses. With this said, the aim here is to investigate whether the Neo-Moorean line could be advanced against the skeptic in a way that wouldn’t require wholesale lowering of epistemic standards. Unfortunately, as we’ll see, Sosa’s (2007; 2009) view as well as what I argue to be the other two most plausible contender-views for maintaining a Neo-Moorean line—Greco’s and Pritchard’s—run (for similar reasons) into dead ends. The way forward, I’ll argue, is to take on board a unique variety of robust virtue epistemology accord­ing to which knowledge is thought to be situated a certain way within a gradient balance between ability and luck.

This paper explores how hinge epistemology might fruitfully be applied not only to the problem of radical skepticism, but also to certain domain specific skepticisms, and in particular, moral skepticism. The paper explains the idea of a domain specific skepticism, and how domain specific skepticisms contrast with radical skepticism. I argue that a domain specific skeptical problem can be resolved in just the same way as radical skepticism, if there are hinge commitments (...) within that domain. I then suggest that there are hinge commitments in the moral domain, and use this to address a moral skeptical problem due to our apparent inability to know moral nihilism to be false. (shrink)

The radical skeptic argues that I have no knowledge of things I ordinarily claim to know because I have no evidence for or against the possibility of being systematically fed illusions. Recent years have seen a surge of interest in pragmatic responses to skepticism inspired by C. S. Peirce. This essay challenges one such influential response and presents a better Peircean way to refute the skeptic. The account I develop holds that although I do not know whether the (...) skeptical hypothesis is true, I still know things I ordinarily claim to know. Although it will emerge that this reply appears similar to a classic contextualist response to radical skepticism, it avoids two central problems facing that response. (shrink)

Is ruling out the possibility that one is dreaming a requirement for a knowledge claim? In “Philosophical Scepticism and Everyday Life” (1984), Barry Stroud defends that it is. In “Others Minds” (1970), John Austin says it is not. In his defense, Stroud appeals to a conception of objectivity deeply rooted in us and with which our concept of knowledge is intertwined. Austin appeals to a detailed account of our scientific and everyday practices of knowledge attribution. Stroud responds that what Austin (...) says about those practices is correct in relation to the appropriateness of making knowledge claims, but that the skeptic is interested in the truth of those claims. In this paper, we argue that Stroud’s defense of the alleged requirement smuggles in a commitment to a kind of internalism, which asserts that the perceptual justification available to us can be characterized independently of the circumstances in which we find ourselves. In our reading of Austin, especially of Sense & Sensibilia, he rejects that kind of internalism by an implicit commitment to what is called today a “disjunctive” view of perception. Austin says that objectivity is an aspect of knowledge, and his disjunctivism is part of an explanation of why the alleged requirement is not necessary for a knowledge claim. Since both Stroud and Austin are committed to the objectivity of knowledge, Stroud may ask which view of perceptual knowledge is correct, whether the internalist or the disjunctive. We argue that by paying closer attention to what Austin says about our practices of knowledge attribution, one can see more clearly that it is grounded not only on a conception of objectivity, but also on a conception of ourselves as information agents, a conception that is as deeply rooted as that of the objectivity of knowledge. This gives us moral and practical reasons to favor the disjunctive view of perception. (shrink)

Are we perhaps in the "matrix", or anyway, victims of perfect and permanent computer simulation? No. The most convincing—and shortest—version of Putnam's argument against the possibility of our eternal envattment is due to Crispin Wright (1994). It avoids most of the misunderstandings that have been elicited by Putnam's original presentation of the argument in "Reason, Truth and History" (1981). But it is still open to the charge of question-begging. True enough, the premisses of the argument (disquotation and externalism) can be (...) formulated and defended without presupposing external objects whose existence appears doubtful in the light of the very skeptical scenario which Putnam wants to repudiate. However, the argument is only valid if we add an extra premiss as to the existence of some external objects. In order to avoid circularity, we should run the argument with external objects which must exist even if we are brains in a vat, e.g. with computers rather than with trees. As long as the skeptic is engaged in a discussion of the brain-in-a-vat scenario, she should neither deny the existence of computers nor the existence of causal relations; for if she does, she is in fact denying that we are brains in a vat.

James Doyle’s book interprets and defends the arguments of G. E. M. Anscombe’s essays “Modern Moral Philosophy” and “The First Person.” Though both essays are widely cited, Doyle argues that in each instance Anscombe’s readers have missed the force of her arguments, which, when properly understood, are able to withstand the common objections to them.Anscombe’s “Modern Moral Philosophy” is commonly read as arguing that talk of moral obligation, permission etc., once had a legitimate place within conceptual frameworks that included the (...) existence of a divine legislator, and can be vindicated outside that framework by adopting the schema of a neo-Aristotelian virtue ethics. But Doyle argues convincingly that this is... (shrink)

Faith has many aspects. One of them is whether absolute logical proof for God’s existence is a prerequisite for the proper establishment and individual acceptance of a religious system. The treatment of this question, examined here in the Jewish context of Rabbi Prof. Eliezer Berkovits, has been strongly influenced in the modern era by the radical foundationalism and radical skepticism of Descartes, who rooted in the Western mind the notion that religion and religious issues are “all or (...) nothing” questions. Cartesianism, which surprisingly became the basis of modern secularism, was criticized by the classical American pragmatists. Peirce, James and Dewey all rejected the attempt to achieve infallible absolute knowledge, as well as the presumptuousness of establishing such a knowledge by means of casting Cartesian hyperbolic doubt. They advocated an alternative approach which was more holistic and humane. This paper lays out Descartes’s approach and the pragmatists’ critique. Despite the place that pragmatic considerations hold in Jewish tradition, some thinkers reject the relevance of these ideas. Yet Berkovits’s thought suggest a different path. He rejected Descartes’ radical skepticism and his radical foundationalism, in favor of a moderate foundationalism, which allows for a belief in God alongside constructive doubts. Similar to Peirce’s conception of the fixation of belief, Berkovits views local doubts (distinct from the hyperbolic doubt) as necessary for thought. Berkovits’s understanding of the biblical human-divine encounter, following Rosenzweig, Buber, and Heschel, is conceptualized here as “encounter theology”. Berkovits criticizes the propositionalist attempts to prove God’s existence logically, as well as the presumptuousness of basing religious belief on the teleological world-order. However, Berkovits’s conception of the ‘caring God’ is not provable, and thus defined as a pragmatic ‘postulate’. The article concludes by considering Berkovits’s “encounter theology”. In contrast to the approach described by Haym Soloveitchik, of halakhic stringency and lack of subjective experience of God’s face, Berkovits’s approach is dialogic through and through. (shrink)

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)

Radical skepticism about the external world is founded on two assumptions: one is that the mind and the external world are logically independent; the other is that all our evidence for the nature of that world consists of facts about our minds. In this paper, I explore the option of denying the epistemic, rather than the logical assumption. I argue that one can do so only by embracing externalism about justification, or, after all, by rejecting the logical independence (...) assumption. Since (I argue) externalism is not a solution to the problem of skepticism, this means that skepticism is false only if the mind and the world are not logically independent. (shrink)

We revisit an important exchange on the problem of radical skepticism between Richard Rorty and Michael Williams. In his contribution to this exchange, Rorty defended the kind of transcendental approach to radical skepticism that is offered by Donald Davidson, in contrast to Williams’s Wittgenstein-inspired view. It is argued that the key to evaluating this debate is to understand the particular conception of the radical skeptical problem that is offered in influential work by Barry Stroud, a (...) conception of the skeptical problem which generates metaepistemological ramifications for anti-skeptical theories. In particular, we argue that, contra Williams, Rorty’s view that Davidson was offering a theoretical diagnosis of radical skepticism can be consistently maintained with his transcendental approach.

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 lack of knowledge—as Timothy Williamson (2000) famously maintains—is ignorance. Radical sceptical arguments, at least in the tradition of Descartes, threaten universal ignorance. They do so by attempting to establish that we lack any knowledge, even if we can retain other kinds of epistemic standings, like epistemically justified belief. If understanding is a species of knowledge, then radical sceptical arguments threaten to rob us categorically of knowledge and understanding in one fell swoop by implying universal ignorance. If, however, (...) understanding is not a species of knowledge, then three questions arise: (i) is ignorance the lack of understanding, even if understanding is not a species of knowledge? (ii) If not, what kind of state of intellectual impoverishment best describes a lack of understanding? (iii) What would a radical sceptical argument look like that threatened that kind of intellectual impoverishment, even if not threatening ignorance? This paper answers each of these questions in turn. I conclude by showing how the answers developed to (i-iii) interface in an interesting way with Virtue Perspectivism as an anti-sceptical strategy.

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.

The point of departure of this paper is the striking similarities between the dispositions critical media literacy education aims to cultivate and the characteristics conspiracy theorists claim to embody. The golden question of critical literacy, “who benefits?” is in fact the central question of conspiracy theorists: “cui bono?” While critical media literacy educators teach learners to disrupt the common sense, to interrogate multiple viewpoints, to focus on sociopolitical issues, and to take actions and promote social justice, conspiracy theorists claim that (...) they do exactly those things. What I wish to illuminate through this juxtaposition, however, is not a way to clearly demarcate “critical” from “conspiratorial” theorizing, but is a question of educational desirability of skepticism. Skepticism in this paper is not understood as a classical epistemological question of the possibility of knowledge attainment, but as a form of vigilance toward epistemic authorities like the government, media, and academic institutions. Drawing on philosophy of conspiracy theories and political epistemology, I illuminate the problem of radical skepticism that characterizes some conspiracy theories and discuss the pivotal epistemic role of trust. Through this, I claim that critical media literacy education for democratic citizenship must strike a balance between cultivation of skepticism and building of trust toward epistemic authorities.

Global meta-philosophical skepticism (i.e. completely unrestricted skepticism about philosophy) based upon disagreement faces the problem of self-defeat since it undercuts its motivating conciliatory principle. However, the skeptic may easily escape this threat by adopting a more modest kind of skepticism, that will be called “extensive meta-philosophical skepticism”, i.e., the view that most of our philosophical beliefs are unjustified, except our beliefs in epistemically fundamental principles. As I will argue in this paper, this kind of skepticism (...) is well-motivated, does not undercut the conciliatory principle, but still poses a radical challenge to philosophy as a cognitive discipline. Moreover, I will argue that non-global skepticism that is still extensive undermines itself as well. The deeper reason for this is that this more modest kind of skepticism can only be motivated by the assumption that disagreement with philosophical peers is abundant and that we can identify peers only by relying on track-record arguments. But then one can argue for extensive meta-philosophical skepticism only if one presupposes that those philosophical beliefs that form the basis of track-record evaluations are justified. Here, the threat of self-defeat looms again. I will proceed by first defending the premises of this new anti-skeptical argument against standard objections from the literature. Second, I will show in more detail where the epistemic inconsistency arises in the argument for extensive meta-philosophical skepticism. I conclude with an assessment of the scope and the limits of my argument. (shrink)

According to Immanuel Kant’s well-known account of his own intellectual development, it was the skeptic David Hume who roused him from his dogmatic slumber. According to some popular accounts of post-Kantian philosophy, it was the soporific speculation of the idealists that quickly returned German philosophy to the Procrustean bed of unverifiable metaphysics, where it dogmatically slept for half of the nineteenth century. This popular picture of post-Kantian German philosophy receives some apparent support from the relevant evidence. After all, Kant had (...) allegedly demonstrated the illegitimacy of all metaphysical speculation that transcends the bounds of experience, and the writings of the German idealists - filled as they are with references to what is putatively “absolute” and “unconditioned” - seem to violate Kant’s strictures. In place of this popular conception, I seek to sketch out a rather difference picture of German idealism. The development of post-Kantian German idealism is best described, not as a turning away from skepticism, but rather as a radicalization of it. The radicalization of skepticism from Kant through Fichte to Hegel, however, does not lead away from systematic philosophy. The movement of thought from Kant to Hegel coincides with the gradual realization that skeptical thought is not external to systematic philosophy, but is in fact internal to, or even identical with it. This thesis concerning the progressive “radicalization” or “internalization” of skepticism in German idealism receives some prima facie support form the relevant writings of Kant, Fichte, and Hegel.

Donald Davidson has argued that attention to the necessarily public character of language shows that we cannot be massively mistaken about the world around us, and that consequently skeptical doubts about empirical knowledge are misplaced. The arguments Davidson advances rely on taking as the fundamental methodological standpoint for investigating meaning and related concepts the standpoint of the interpreter of another speaker, on the grounds that it is from the interpreter’s standpoint that we discover what constraints are placed on meaning by (...) the public character of language. In this paper, I argue that although Davidson’s arguments reveal important conceptual connections between meaning and belief on the one hand, and truth and interpretation on the other, they do not show that it is impossible that we are massively mistaken about the external world.

Epistemological disjunctivism is a philosophical theory that has received special attention in the recent years. Particularly because it has been seen by many as a way of renewing discussions that range from the nature of justification of our daily beliefs to the possibility of unveiling the structure of the problem of radical skepticism and of responding to it. Duncan Pritchard is one of the authors who have offered a particular view of disjunctivism and ways of conceiving of disjunctivist (...) treatments to such questions. His work has as its main source of inspiration the seminal work of John McDowell. In this paper, I present a way of understanding the problem ofradicalskepticism and the mannerin which epistemological disjunctivism aimsto offer solutionsto it. In orderto do that, I present McDowell’s general proposal and discuss in which way his account differs from Pritchard’s own disjunctivism. At the end, I try to show how Pritchard’s approach tries to respond to radical skepticism not only by appealing to a disjunctivist reading of our epistemic position, but also by offering a revision of our structure of reasons.

In this paper, I attempt to show how Davidson’s anti-sceptical argument can respond to the closureRK-based radical scepticism. My approach will focus on the closureRK principle rather than the possibility that our beliefs could be massively wrong. I first review Davidson’s principle of charity and the triangulation argument, and then I extract his theory on content of a belief. According to this theory, content of a belief is determined by its typical cause and other relevant beliefs. With this constraint (...) on content, I argue that doubt must be local. Furthermore, since one cannot rationally believe that one’s commitment to the cause of beliefs could be false, our commitment to the denial of a sceptical hypothesis is not a knowledge-apt belief. Therefore, the closureRK principle is not applicable to rational evaluations of this commitment. As a result, the closureRK-based sceptical argument fails while the closureRK principle remains.

Wouter Kusters argues that madness has much to offer philosophy, as does philosophy to madness. In this paper, i support both claims by drawing on a mad phenomenon which I label Radical Psychotic Doubt, or RPD. First, although skepticism is a minority position in epistemology, it has been claimed that anti-skeptical arguments remain unsatisfying. I argue that this complaint can be clarified and strengthened by showing that anti-skeptical arguments are irrelevant to RPD sufferers. Second, there's a debate about (...) whether so-called hinge commitments are beliefs or not. I argue that RPD can be used to strengthen the case that they are. Moreover, if hinges are beliefs, some madpeople are more epistemically rational than some sane philosophers. Third, drawing on my own mad experiences, I challenge evidentialism by presenting a better candidate for a truly forced cchoice about what to believe than William James' traditional religious example. I further show that in certain psychiatric contexts, evidentialism has more radical implications than Jamesian pragmatism, which comes out as more conservative. Finally, I discuss how philosophical theories like pragmatism and Pyrrhonism can provide inspiration for new and much-needed coping strategies for RPD sufferers. (shrink)

In this paper, I present and criticize a number of influential anti-skeptical strategies inspired by Wittgenstein’s remarks on ‘hinges’. Furthermore, I argue that, following Wittgen- stein’s analogy between ‘hinges’ and ‘rules of grammar’, we should be able to get rid of Cartesian skeptical scenarios as nonsensical, even if apparently intelligible, combinations of signs.

This paper responds to the Radical Behavioral Challenge to normative business ethics. According to RBC, recent research on bounded ethicality shows that it is psychologically impossible for people to follow the prescriptions of normative business ethics. Thus, said prescriptions run afoul of the principle that nobody has an obligation to do something that they cannot do. I show that the only explicit response to this challenge in the business ethics literature is flawed because it limits normative business ethics to (...) condemning practitioners’ behavior without providing usable suggestions for how to do better. I argue that a more satisfying response is to, first, recognize that most obligations in business are wide-scope which, second, implies that there are multiple ways of fulfilling them. This provides a solid theoretical grounding for the increasingly popular view that we have obligations to erect institutional safeguards when bounded ethicality is likely to interfere with our ability to do what is right. I conclude with examples of such safeguards and some advice on how to use the research findings on bounded ethicality in designing ethical business organizations. (shrink)

Rationalism, my target, says that in order to have perceptual knowledge, such as that your hand is making a fist, you must “antecedently” (or “independently”) know that skeptical scenarios don’t obtain, such as the skeptical scenario that you are in the Matrix. I motivate the specific form of Rationalism shared by, among others, White (Philos Stud 131:525–557, 2006) and Wright (Proc Aristot Soc Suppl Vol 78:167–212, 2004), which credits us with warrant to believe (or “accept”, in Wright’s terms) that our (...) senses are reliably veridical, where that warrant is one we enjoy by default, that is, without relying on any evidence or engaging in any positive argument. The problem with this form of Rationalism is that, even if you have default knowledge that your senses are reliable, this is not adequate to rule out every kind of skeptical scenario. The problem is created by one-off skeptical scenarios, scenarios that involve a highly reliable perceiver who, by a pure fluke, has a one-off, non-veridical experience. I claim you cannot infer that your present perceptual experience is veridical just on the basis of knowledge of your general reliability. More generally, if you infer that the present F is G, just on the basis of your knowledge that most Fs are Gs, this is what I call statistical inference, and, as I argue, statistical inference by itself does not generate knowledge. I defend this view of statistical inference against objections, including the objection that radical skepticism about our ordinary inductive knowledge will follow unless statistical inference generates knowledge.

This work aims to present and discuss recent developments in epistemology that seek for satisfactory formulations and responses to the problem of radical skepticism. Its main goal is to understand how the skeptical problem can be properly characterized, how it can be viewed as inserted in the traditional dispute in epistemology between externalism and internalism, and to which extent antiskeptical theories are situated within this dispute. After identifying their place in the dispute, another antiskeptical proposal is discussed, one (...) that suggests a conciliatory take on the internalist/externalist debate. The way Duncan Pritchard presents this conciliatory view, known as epistemological disjunctivism, intends to show that we can know the things that radical skepticism wants to preclude us to know. In order to do that, we just have to consider our structure of reasons as one that allows us to have factive reasons, reasons of externalist and internalist nature, that could put us in a privileged position to know the things we ordinarily believe. After the presentation and discussion of Pritchard's epistemological disjunctivism, and his general rejection of skepticism, it is suggested that its antiskeptical tools are also available to more traditional epistemic theories - but to access them, some epistemological assumptions need to be adjusted. In order to do that, an alternative take on the internalism/externalism dispute is offered, so it can allow for a different way of conceiving the conciliatory antiskeptical strategy, one that has epistemic reliabilism as its framework. The final propposal consists in an attempt to democratize the disjunctivist tool against radical skepticism. (shrink)

The paper advances the hypothesis that René Descartes presents a skeptical system of philosophy in Thomas Reid’s reading. There is a sort of ‘involun-tary’ or ‘accidental’ skepticism that results from the adoption by Descartes of both a skeptical method and a skeptical principle. The first section shows to what extent the Cartesian method of doubt – which focuses on the reliability of the faculties of the mind - is a skeptical demand that cannot be satisfied. The second section shows (...) how the principle of the Cartesian system – which establishes that ideas are the immediate objects of the operations of the mind – is not only skeptic but leads exactly and naturally to the most radical form of skepticism, namely, solipsism. The third section discusses the Cartesian sources of the doubt on the existence of external world according to Reid. (shrink)

JOURNAL OF THE HISTORY OF PHILOSOPHY PRIZE for the best published book in the history of philosophy [Awarded in 2010] _______________ -/- Although it is widely recognized that David Hume's A Treatise of Human Nature (1739-40) belongs among the greatest works of philosophy, there is little agreement about the correct way to interpret his fundamental intentions. It is an established orthodoxy among almost all commentators that skepticism and naturalism are the two dominant themes in this work. The difficulty has (...) been, however, that Hume's skeptical arguments and commitments appear to undermine and discredit his naturalistic ambition to contribute to "the science of man". This schism appears to leave his entire project broken-backed. The solution to this riddle depends on challenging another, closely related, point of orthodoxy: namely, that before Hume published the Treatise he removed almost all material concerned with problems of religion. Russell argues, contrary to this view, that irreligious aims and objectives are fundamental to the Treatise and account for its underlying unity and coherence. It is Hume's basic anti-Christian aims and objectives that serve to shape and direct both his skeptical and naturalistic commitments. When Hume's arguments are viewed from this perspective we can solve, not only puzzles arising from his discussion of various specific issues, we can also explain the intimate and intricate connections that hold his entire project together. This "irreligious" interpretation provides a comprehensive fresh account of the nature of Hume's fundamental aims and ambitions in the Treatise. It also presents a radically different picture of the way in which Hume's project was rooted in the debates and controversies of his own time, placing the Treatise in an irreligious or anti-Chrisitan philosophical tradition that includes Hobbes, Spinoza and freethinking followers. Considered in these terms, Hume's Treatise constitutes the crowning achievement of the Radical Enlightenment. (shrink)

This paper argues that McDowell wrongly assumes that “terror”, Cavell’s reaction to the radical contingency of our shared modes of knowing or our “attunement”, expresses a skepticism that is antinomically bound to an equally unacceptable dogmatism because Cavell rather regards terror as a mood that reveals the “truth of skepticism”, namely, that there is no conclusive evidence for necessary attunement on pain of a category error, and that a precedent for McDowell’s misunderstanding is Hegel’s argument for necessary (...) attunement in a system of knowing, whose refutation Schelling holds it is the “merit of skepticism” to provide.

This paper analyzes the way in which skepticism led to the crisis of the criteria of truth and action that developed in Stoic philosophy. The attempts of the skeptics to escape the difficulties caused by their radical philosophical views are presented. Special attention was paid to the importance that yielding to the customs and traditions of the community in which they lived had in the life of skeptics deprived of these criteria. This approach to action and problem solving (...) in general has a special significance and value in times of crisis, and it is often easy to overlook. (shrink)

The paper states a hypothesis concerning Thomas Reid's moderation in his reply to skepticism. It is initially argued that commonsense beliefs, though due to reliable faculties, are doubtful, fallible, and correctable. They are not completely immune to skeptical attack. It is further argued that Reid intends to reply only to one form of skepticism, the partial one – the skepticism of authors who accept at least one mental faculty as a reliable source of knowledge. Reid does not (...) intend to argue with the skeptic who equally denies his assent to the reliability of all faculties – that is, the radical skeptic. This radical form of skepticism is harmless to practical life and philosophy and, for that reason, is not a threat. Finally, the hypothesis advanced is discussed considering other interpretations of Reid’s reply to skepticism. (shrink)

Commentators have noticed the striking similarities between the skep­tical arguments of al-Ghazālī’s Deliverance from Error and Descartes’ Discourse on Method and Meditations on First Philosophy. However, commentators agree that their solutions to skepticism are radically different. Al-Ghazālī does not use rational proofs to defeat skepticism; rather, he relies on a supernatural light [nūr] sent by God to rescue him from skepticism. Descartes, on the other hand, relies on the natural light of reason [lumen naturale] to prove the (...) existence of God, mind, and body. In this paper, I argue that Descartes’ solution is closer to al-Ghazālī’s than commentators have allowed. A close reading of the cosmological argument of the Third Meditation reveals that there is also a type of divine intervention em­ployed in the Meditations, which helps Descartes defeat skepticism. This reading may buttress the case made by some that al-Ghazālī influenced Descartes; but more importantly, it requires us to rethink key features of Descartes’ epistemology. (shrink)

We argue that knowledge doesn‘t require any of truth, justification, or belief. This is so for four primary reasons. First, each of the three conditions has been subject to convincing counterexamples. In addition, the resultant account explains the value of knowledge, manifests important theoretical virtues (in particular, simplicity), and avoids commitment to skepticism.

Radical skepticism is the view that we know nothing or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an (...) interaction between two factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e., that something is not the case) than when it is positive (i.e., that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

A recent study dealing with Western European countries suggests a connection between vaccine skepticism and support for populist parties (Kennedy 2019). Of all countries in the study, Italy scored highest on both counts, with 44% of the electorate voting for populists in 2014 and 14% of the population not deeming vaccinations important. The study concludes that both phenomena have a common root in the distrust of elite and experts. While that seems plausible, this paper establishes that there is much (...) more to be said about the relation between populism and the anti-vaccination movement. Using the case study of the Italian anti-vaxxers, I spell out how populists have reinforced an echo chamber in an effort to mobilize it. I argue that besides the common root cause, in this instance there is also indication of a causal relation between populism and anti-vaccination. Moreover, I show that populism and echo chambers in general are conceptually linked through their dichotomous division of society and rejection of legitimate opposition. (shrink)

The focus of this chapter will be Kant’s understanding of Hume, and its impact on Kant’s critical philosophy. Contrary to the traditional reading of this relationship, which focuses on Kant’s (admittedly real) dissatisfaction with Hume’s account of causation, my discussion will focus on broader issues of philosophical methodology. Following a number of recent interpreters, I will argue that Kant sees Hume as raising, in a particularly forceful fashion, a ‘demarcation challenge’ concerning how to distinguish the legitimate use of reason in (...) (say) natural scientific contexts from the illegitimate use of it in (say) dogmatic metaphysics. I will then go on to argue that Kant sees Hume’s tendency to slide into more radical forms of skepticism as a symptom of his failure to provide a systematic or principled account of this distinction. This failure, I argue, can be traced (according to Kant) to Hume’s impoverished, non-hylomorphic account of our faculties – which both robs Hume of the materials necessary to construct a genuinely systematic philosophy as Kant understands this, and makes it impossible for Hume to clearly conceive of what Kant calls ‘Formal Idealism.’ In this way, the failings of Hume’s account of causation are (for Kant) symptoms of more fundamental limitations within Hume’s philosophy. I close by briefly discussing the similarities between Hume and Kant’s understanding of the relationship between, first, philosophical methodology and, second, the nature of our faculties. (shrink)

Many interpretations of Kant’s first Critique fail to appreciate the revolutionary nature of his account of knowledge and its implications for skepticism, givenness and mind-independence, because they read Kant as holding a compositional account of knowledge. I contend that the reason for this is that this account is both naturally appealing in its own right, and fits an influential reading of Kant’s Transcendental Deduction. On this reading, the Deduction aims to respond to a skeptical worry which issues from the (...) empiricist version of epistemic compositionalism and which questions the intelligibility of the claim to knowledge of our judgements. Against this, I argue that what Kant’s Deduction actually aims to address is a radicalization of this epistemic worry, which instead questions the intelligibility of the objective purport of our judgements. I contend that the compositional account is unable to respond to this more radical worry, thereby putting it into question both as a reading of Kant, and as an account of knowledge generally. To corroborate this, I provide a reading of the Deduction that overcomes epistemic compositionalism by thinking through its shortcomings in order to arrive at a more adequate successor account: the hylomorphic account of knowledge, which, I contend, is able to dissolve both the more radical and the epistemic worry. I suggest that this implies generally that the epistemic worry issuing from the compositional account is not self-contained, but must give way to Kant’s more radical worry, which I argue can only be addressed within the underappreciated framework of epistemic hylomorphism.

Free will skepticism is radical in its core claim that free will is illusory. Criminal law, however, appears to presuppose that persons are free and hence, morally responsible for their actions. So, if free will skepticism is true, our current practices that hold people to account for their wrongs appears unjustified–even immoral. This paper will challenge the free will skeptic’s core claim that free will does not exist and defend current practices of moral responsibility by offering (and (...) defending) a Frankfurtian-compatibilist approach to the topics of free will and determinism.

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)

There are four main positions in the argument about whether God exists: atheism, theism, agnosticism, and scepticism. From an epistemological standpoint, scepticism is the most rational; even if a decisive argument which would settle the debate has not been discovered yet, one cannot exclude the possibility of finding it eventually. Agnosticism is too radical, but theism and atheism exceed the available data. However, from a practical standpoint, choosing theism or atheism seems to be more rational than scepticism ; one (...) of them is bound to be right, because there are only two possibilities, one of which has to be true: either God exists or not.

Part 1 of this paper discusses some uses of arguments from radical moral disagreement—in particular, as directed against absolutist cognitivism—and surveys some semantic issues thus made salient. It may be argued that parties to such a disagreement cannot be using the relevant moral claims with exactly the same absolutist cognitive content. That challenges the absolutist element of absolutist cognitivism, which, combined with the intractable nature of radical moral disagreement, in turn challenges the viability of a purely cognitivist account (...) of moral judgments. Such a conclusion could be staved off if it could be held that a sufficient condition for commonality of cognitive content in moral judgments could consist, despite the presence of radical moral disagreement, in the parties’acceptance of a common set of fundamental moral principles. Part 1 begins, and Part 2 further develops, a destructive critique of that idea, leading thereby to a skeptical appraisal of the important role sometimes assigned, in metaethical theorizing, to moral rules. Inter alia the paper is intended to suggest the possibility of overlap between relativist and particularist agendas. (shrink)

Political philosophy has been under the sway of a certain picture since Rawls's A Theory of Justice was published in 1971. This picture com- bines the idea that the problem of justice should be approached from the direction oi ideal normative theory, and that there are some anchor- ing ideas that secure the justificatory role of a hypothetical agreement. I think this picture and the hold it has over political philosophy is beginning to fragment. This fragmentation I think is most (...) evident in the skepticism that has become a routine response to the Kantian idea that 'we' can 'discover' the terms of an agreement that has both a categorical force and a universal scope. But as the picture fragments we are still left with the framework and vocabulary of Rawls's difficult and elaborate theory. The major difficulty confronting the Rawlsian project (the problem of pluralism as I will argue below) is itself defined in terms of Rawls's conceptual language. And this serves only to obscure the real challenge and keep us 'bewitched' by Rawls's nar- row way of seeing issues. In being bewitched in this way we do not see that the problem of pluralism confronts Rawls's project as a whole, rather than requiring adjustments and accommodations. (shrink)

Critics of skeptical theism often claim that if it (skeptical theism) is true, then we are in the dark about whether (or for all we know) there is a morally justifying for God to radically deceive us. From here, it is argued that radical skepticism follows: if we are truly in the dark about whether there is a morally justifying reason for God to radically deceive us, then we cannot know anything. In this article, I show that skeptical (...) theism does not entail that we are in the dark about whether (or for all we know) there is a morally justifying reason for God to deceive us. And hence arguments against skeptical theism that make use of this assumption fail. (shrink)

Epistemologists understand radical skepticism as arising from two principles: Closure and Underdetermination. Both possess intuitive prima facie support for their endorsement. Understanding how they engender skepticism is crucial for any reasonable anti-skeptical attempt. The contemporary discussion has focused on elucidating the relationship between them to ascertain whether they establish distinct skeptical questions and which of the two constitutes the ultimately fundamental threat. Major contributions to this debate are due to Brueckner, Cohen, and Pritchard. This contribution aims at (...) defending Brueckner’s contention that underdetermination expresses the fundamental skeptical threat and that the closure-based argument can ultimately be reduced to it, at least concerning skeptical contexts. This will be achieved by undermining Cohen’s objections to Brueckner on both counts. Cohen’s argument endorses a picture of evidential underdetermination, which, while apt for non-skeptical contexts, cannot be applied to radical skepticism. A comparison with a case of scientific underdetermination is developed to argue for this idea. Our argument is then applied to the principle equivalence issue and to objections against it. It is then shown how this analysis possesses a distinctive effect on our understanding of the skeptical threat and the assessment of successful anti-skeptical strategies. (shrink)

A perceptual realism that is naive in a good way must be naively realistic about world and mind. But contemporary self-described naive realists often have trouble acknowledging that both the good cases of successful perception and the bad cases of illusion and hallucination involve internal experiential states with intentional contents that present the world as being a certain way. They prefer to think about experience solely in relational terms because they worry that otherwise we won’t be able to escape from (...) radical skepticism. I argue that experiential relations to objects require that their subjects be in internal experiential states. But this does not mean that these states are our epistemological starting point which can be known independently of any knowledge of the external world. We do escape the epistemological predicament of radical skepticism because the good cases are primary over the bad ones. But this is not because the good cases alone provide reasons for belief, but because we do not need a reason to think we are in a good case, but do need a reason to think we are not, and such a reason must come from a good case. So bad cases can only be thought of as deviations from good cases. And we can only understand experiences as states with contents distinct from their objects and present in good and bad cases once we understand misrepresentation, that is, bad cases, and therefore only as we ascribe knowledge of the external world to ourselves.

This is a critical commentary on Pritchard's book Epistemic Angst. In Section 2, I present the closure-based radical skeptical paradox. Then in Section 3, I sketch Pritchard’s undercutting response to this paradox. Finally, in Section 4, I put forward two concerns about Pritchard’s response and I also propose a reading of hinge commitments, the ability reading, that might put some pressure on Pritchard’s own reading of these commitments.

Nietzsche, in his work On the Genealogy of Morals, argues that human cognition is analogous in certain significant respects to the perspectival nature of optical vision. Because of this analogy, his account of human cognition is often referred to as perspectivism. Brian Leiter argues that Nietzsche’s use of this optical perspective metaphor undermines interpretations that take perspectivism to have radically skeptical implications. In this paper, I examine Leiter’s argument and show that the considerations he raises based on the optical perspective (...) metaphor are insufficient to undermine the claim that perspectivism entails radical skepticism.

Philosophers often find themselves in disagreement with contemporary philosophers they know full well to be their epistemic superiors on the topics relevant to the disagreement. This looks epistemically irresponsible. I offer a detailed investigation of this problem of the reflective epistemic renegade. I argue that although in some cases the renegade is not epistemically blameworthy, and the renegade situation is significantly less common than most would think, in a troublesome number of cases in which the situation arises the renegade is (...) blameworthy in her disagreement with recognized epistemic superiors. I also offer some thoughts on what it would mean for philosophical practice for us to refrain from being renegades. Finally, I show how a new kind of radical skepticism emerges from modest theses regarding the renegade. (shrink)

Nietzsche offers a positive epistemology, and those who interpret him as a skeptic or a mere pragmatist are mistaken. Instead he supports what he calls per- spectivism. This is a familiar take on Nietzsche, as perspectivism has been analyzed by many previous interpreters. The present paper presents a sketch of the textually best supported and logically most consistent treatment of perspectivism as a first- order epistemic theory. What’s original in the present paper is an argument that Nietzsche also offers a (...) second-order methodological perspectivism aimed at enhancing understanding, an epistemic state distinct from knowledge. Just as Descartes considers and rejects radical skepticism while at the same time adopting methodological skepticism, one could consistently reject perspectivism as a theory of knowledge while accepting it as contributing to our understanding. It is argued that Nietzsche’s perspectivism is in fact two-tiered: knowledge is perspectival because truth itself is, and in addition there is a methodological perspectivism in which distinct ways of knowing are utilized to produce understanding. A review of the manner in which understanding is conceptualized in contemporary epistemology and philosophy of science serves to illuminate how Nietzsche was tackling these ideas. (shrink)

I have developed transcendental arguments to refute several versions of Nick Bostrom’s simulation hypothesis. I called some of these arguments the SIM-style argument. In this paper, I have four main aims. First, I employ the SIM-style argument to remedy a defect in Hilary Putnam’s Brain-in-vat argument. Second, I show that the most radical skepticism, which Tim Button called the nightmarish Cartesian skepticism, can be refuted by the SIM-style argument or by another transcendental argument I develop here. Third, (...) I compare my approach to radical skepticisms with Donald Davidson’s, as it is often regarded as an exemplar of transcendental arguments. Fourth, I explain how the prominent objections, mainly developed by Barry Stroud, to transcendental arguments can incur two undesirable results: psychologism and Kantian skepticism. (shrink)
