Radical skepticism endorses the extreme claim that large swaths of our ordinary beliefs, such as those produced by perception or memory, are irrational. The best arguments for such skepticism are, in their essentials, as familiar as a popular science fiction movie and yet even seasoned epistemologists continue to find them strangely seductive. Moreover, although most contemporary philosophers dismiss radical skepticism, they cannot agree on how best to respond to the challenge it presents. In the tradition (...) of the 18th century Scottish philosopher, Thomas Reid, Radical Skepticism and Epistemic Intuition joins this discussion by taking up four main tasks. First, it identifies the strongest arguments for radical skepticism, namely, underdetermination arguments, which emphasize the gap between our evidence and our ordinary beliefs based on that evidence. Second, it rejects all inferential or argument-based responses to radical skepticism, which aim to lay out good noncircular reasoning from the evidence on which we base our ordinary beliefs to the conclusion that those beliefs are probably true. Third, it develops a commonsense noninferential response to radical skepticism with two distinctive features: it consciously and extensively relies on epistemic intuitions, which are seemings about epistemic goods, such as knowledge and rationality, and it can be endorsed without difficulty by both internalists and externalists in epistemology. Fourth, and finally, it defends this commonsense epistemic-intuition-based response to radical skepticism against a variety of objections, including those connected with underdetermination worries, epistemic circularity, disagreement problems, experimental philosophy, and concerns about whether it engages skepticism in a sufficiently serious way.

Epistemic Angst offers a completely new solution to the ancient philosophical problem of radical skepticism—the challenge of explaining how it is possible to have knowledge of a world external to us. Duncan Pritchard argues that the key to resolving this puzzle is to realize that it is composed of two logically distinct problems, each requiring its own solution. He then puts forward solutions to both problems. To that end, he offers a new reading of Wittgenstein's account of the (...) structure of rational evaluation and demonstrates how this provides an elegant solution to one aspect of the skeptical problem. Pritchard also revisits the epistemological disjunctivist proposal that he developed in previous work and shows how it can effectively handle the other aspect of the problem. Finally, he argues that these two antiskeptical positions, while superficially in tension with each other, are not only compatible but also mutually supporting. The result is a comprehensive and distinctive resolution to the problem of radical skepticism, one that challenges many assumptions in contemporary epistemology. (shrink)

Donald Davidson famously argued, contra radical skepticism, that belief is in its nature veridical. In assessing whether Davidson was successful in this regard, it is first necessary to establish the exact philosophical basis Davidson was adducing for this claim, which is far from clear. In particular, a lot of the critical focus on Davidson's approach to radical skepticism has tended to focus on his appeal to an omniscient interpreter, and yet a closer evaluation of Davidson's antiskepticism (...) reveals that this notion is almost certainly dialectically inessential. Following some introductory remarks, in Section 2, I outline how the project of radical interpretation, and the associated principle of charity, are key parts of the philosophical background to Davidson's argument against radical skepticism. In Section 3, I critically evaluate Davidson's appeal to an omniscient interpreter. In Section 4, I demonstrate the role that Davidson's specific brand of content externalism plays in his antiskepticism, in particular in virtue of his notion of triangulation. Finally, in Section 5 I consider, and defend, an interpretation of Davidson's view that treats it as a kind of transcendental argument against 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.

Support is canvassed for a novel solution to the sceptical problem regarding our knowledge of the external world. Key to this solution is the claim that what initially looks like a single problem is in fact two logically distinct problems. In particular, there are two putative sceptical paradoxes in play here, which each trade on distinctive epistemological theses. It is argued that the ideal solution to radical scepticism would thus be a biscopic proposal—viz., a two-pronged, integrated, undercutting treatment of (...) both putative sceptical paradoxes. A particular biscopic proposal is then explored which brings together two apparently opposing anti-sceptical theses: he Wittgensteinian account of the structure of rational evaluation and epistemological disjunctivism. It is argued that each proposal enables us to gain a purchase on one, but only one, aspect of the two-sided sceptical problem. Furthermore, it is argued that these proposals are not only compatible positions, but also mutually supporting and advanced in the same undercutting spirit. A potential cure is thus offered for epistemic angst. (shrink)

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)

This discussion surveys recent developments in the treatment of the epistemological problem of skepticism. These are arguments which attack our knowledge of certain truths rather than, say, our belief in the existence of certain entities. In particular, this article focuses on the radical versions of these skeptical arguments, arguments which purport to show that knowledge is, for the most part, impossible, rather than just that we lack knowledge in a particular discourse. Although most of the key recent developments (...) in this area have taken place since the late 1980s and early 1990s, it is necessary to also discuss some of the movements that have developed since 1970 in order to give these recent developments the necessary setting. The date of 1970 is dictated by the publication in that year of Fred Dretske’s seminal article “Epistemic Operators,” which both pushed a “relevant alternatives” theory of knowledge to the fore of discussion and also brought into focus one possible line of argument against the so-called “closure” principle for knowledge. In so doing, it provided one of the main sources of response to the emergent.. (shrink)

Michael Bergmann's Radical Skepticism and Epistemic Intuition develops a response to radical skepticism inspired by commonsense philosophers, such as Reid and Moore. Bergmann argues against radical skepticism on the grounds of its conflicting with strongly-held "epistemic intuitions" about the "epistemic value or goodness” of our particular perceptual, recollective, introspective and a priori beliefs. I press concerns about whether Bergmann's "intuitionist particularist" response can diagnose the source of skepticism, and argue that his methodology turns (...) out to itself be strikingly skeptical.

I defend the view that Cicero writes the Academica from the perspective of an aspirationalist radical skeptic. In section 2 I examine the textual evidence regarding the nature of Cicero’s skeptical stance in the Academica. In section 3 I consider the textual evidence from the Academica for attributing aspirationalism to Cicero. Finally, in section 4 I argue that while aspirationalist radical skepticism is open to a number of philosophical objections, none of those objections is decisive.

ABSTRACTHilary Putnam provides an anti-skeptical argument motivated by semantic externalism. He argues that our best theorizing about what it takes to experience, think, and so on, entails that the world is much as we take it to be. This fact eliminates the possibility of radical skeptical scenarios, where from our perspective everything seems as it does in the actual case, but we are widely and systematically mistaken. I think that this approach is generally correct, and that it is the (...) most promising strategy for undermining radical skepticism. There are, however, well-discussed difficulties with Putnam's way of pursuing this strategy. I argue that in order to avoid these objections we will have to be more radical externalists than Putnam proposed; in particular, we will have to beperspectival externalists. According to perspectival externalism, a subject's reliable relations to her environment play a crucial role in determining not only the contents of her mental events, but also what it is like for her to grasp those contents. While semantic externalism is widely accepted in epistemology, perspectival externalism is not. I argue that perspectival externalism is independently more plausible than mere semantic externalism, and that such an account can enable us to better pursue Putnam's anti-skeptical strategy.

A great deal of discussion in the recent literature has been devoted to the so-called 'McKinsey' paradox which purports to show that semantic externalism is incompatible with the sort of authoritative knowledge that we take ourselves to have of our own thought contents. In this paper I examine one influential epistemological response to this paradox which is due to Crispin Wright and Martin Davies. I argue that it fails to meet the challenge posed by McKinsey but that, if it is (...) set within an externalist epistemology, it may have application to a related paradox that concerns the problem of radical scepticism.

In this précis of Radical Skepticism and Epistemic Intuition, I highlight the main lines of argument in the book and provide an outline of each of the book’s three parts. I explain how: Part I lays out an argument for radical skepticism and objects to one of the two main ways of responding to it; Part ii presents my version of the other main way of responding to that skeptical argument (a version that relies heavily on (...) epistemic intuition); and Part iii defends epistemic intuition (and, thereby, my response to radical skepticism) from several important objections.

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)

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)

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)

It is becoming increasingly apparent that Elizabeth Anscombe, long known as a student, friend and translator of Wittgenstein, was herself one of the most important philosophers of the twentieth century. No Morality, No Self examines her two best-known papers, in which she advanced her most amazing theses. In 'Modern Moral Philosophy', she claimed that the term moral, understood as picking out a special, sui generis category, is literally senseless and should therefore be abandoned. In 'The First Person', she maintained that (...) the word 'I' is not a referring expression: in other words, its function in the language is not to pick out the speaker, or 'the self' - or any entity whatsoever. Both papers are considered influential, and are frequently cited; but their main claims, and many of their arguments, have been widely misunderstood. In this book James Doyle shows that once various errors of interpretation have been cleared away, the claims can be seen to be far more plausible, and the arguments far more compelling, than even her defenders have realized. Philosophers often seek attention by making startling claims which are subsequently revealed as little more than commonplaces wrapped in hyperbole. Doyle's book makes it clear that here, in her greatest papers, Anscombe achieves something vanishingly rare in philosophy: a persuasive case for genuinely unsettling and profound conclusions. The two lines of argument, seemingly so disparate, are also shown to be connected by Anscombe's deep opposition to the Cartesian picture of the mind.--. (shrink)

In this paper, I present and criticize a number of influential contemporary anti-skeptical strategies inspired by G.E. Moore’s “proof of an external world”. I argue that these accounts cannot represent a valid response to skeptical worries. Furthermore, drawing on Wittgenstein’s criticisms of Moore, I argue that Radical skeptical hypotheses should be considered nonsensical combinations of signs, excluded from our epistemic practices.

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.

I begin by making some brief remarks about commonsense particularism. Commonsense particularists hold that we know pretty much what we think we know and hold that some of these beliefs are more reasonable than competing skeptical principles. However, commonsense philosophers often differ about what justifies these particular beliefs. Michael Bergmann holds that that our commonsense epistemic beliefs depend for their justification on epistemic intuitions or epistemic seemings. After a brief description of his views, I raise some questions about the nature (...) and epistemic role of these epistemic seemings. (shrink)

James Doyle’s book interprets and defends the arguments of G. E. M.

But Doyle argues convincingly that this is... (shrink)

Baron Reed has developed a new argument for skepticism: (1) contemporary epistemologists are all committed to two theses, fallibilism and attributabilism; unfortunately, (2) these two theses about knowledge are incompatible; therefore, (3) knowledge as conceived by contemporary epistemologists is impossible. In this brief paper I suggest that Reed's argument appears to rest on an understanding of attributabilism that is so strong (call it maximal attributabilism) that it's doubtful that many contemporary epistemologists actually embrace it. Nor does Reed offer any (...) direct argument for the truth of maximal attributabilism. Therefore, we need not be persuaded by Reed's new argument for skepticism. (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)

A study of how contemporary cinema and film-philosophers explore radical skepticism about our knowledge of the world.

Goodman concurs in Hume’s contention that no theory has any probability relative to any set of data, and offers two accounts, compatible with that contention, of how some inductive inferences are nevertheless justified. The first, framed in terms of rules of inductive inference, is well known, significantly flawed, and enmeshed in Goodman’s unfortunate entrenchment theory and view of the mind as hypothesizing at random. The second, framed in terms of characteristics of inferred theories rather than rules of inference, is less (...) well known, but provides a compelling view of inductive justification. Once the two accounts are clearly delineated, one can see that both are driven by a single deep conviction: that inductive justification can only be understood in terms of our actual inductive practice.

This paper critically surveys 20 years of recent work on radical skepticism. It focuses on three key issues. First, it starts by exploring how philosophers have recently challenged our understanding of radical skeptical arguments. It then unpacks and critically evaluates some influential reactions to radical skepticism: structuralism, knowledge-first epistemology, epistemological disjunctivism, and hinge epistemology. Third, it explores some novel developments of pragmatism, like pragmatic skepticism, gauges its anti-skeptical import, and reflects on the ways in (...) which radical skeptical epistemology and ethics might meet.

Skepticism is one of the perennial problems of philosophy: from antiquity, to the early modern period of Descartes and Hume, and right through to the present day. It remains a fundamental and widely studied topic and, as Annalisa Coliva and Duncan Pritchard show in this book, it presents us with a paradox with important ramifications not only for epistemology but also for many other core areas of philosophy. In this book they provide a thorough grounding in contemporary debates about (...) skepticism, exploring the following key topics: the core skeptical arguments, with a particular focus on Cartesian and Humean radical skepticism. the epistemic principles that are held to underlie skeptical arguments, such as the closure and underdetermination principles. the content externalism of Putnam, Davidson and Chalmers, and how it might help us respond to radical skepticism. the epistemic externalism/internalism distinction and how it relates to the skeptical problematic. contextualism in epistemology and its anti-skeptical import. the various interpretations of a Wittgensteinian hinge epistemology. the viability of epistemological disjunctivism, including whether it can be combined with hinge epistemology as part of a dual response to radical skepticism. liberal and conservative responses to the Humean skeptical paradox. Both authors are themselves prominent figures who work on skepticism, and so one novelty of the book is that it provides an insight into their own contrasting responses to this philosophical difficulty. With the addition of annotated further reading and a glossary this is an ideal starting point for anyone studying the philosophy of skepticism, along with students of epistemology, metaphysics and contemporary analytic philosophy.

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)

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