The Cartesian arguments for external world skepticism are usually considered to be significant for at least two reasons: they seem to present genuine paradoxes and that providing an adequate response to these arguments would reveal something epistemically important about knowledge, justification, and/or our epistemic position to the world. Using only premises and reasoning the skeptic accepts, I will show that the most common Cartesian argument for external world skepticism leads to a previously unrecognized self-undermining dilemma: it either leads to a (...) reductio ad absurdum, or to avoid this reductio the skeptic must accept that this argument is epistemically idle—it does not provide any support for external world skepticism. Either way, this Cartesian argument cannot legitimately threaten or even call into question our beliefs about the external world. And thus, either way, this Cartesian argument for external world skepticism is not epistemically significant—it is not a genuine paradox and adequately responding to it need not reveal anything epistemically important.

In the Essay Concerning Human Understanding, Locke insists that all knowledge consists in perception of the agreement or disagreement of ideas. However, he also insists that knowledge extends to outer reality, claiming that perception yields ‘sensitive knowledge’ of the existence of outer objects. Some scholars have argued that Locke did not really mean to restrict knowledge to perceptions of relations within the realm of ideas; others have argued that sensitive knowledge is not strictly speaking a form of knowledge for Locke. (...) This chapter argues that Locke’s conception of sensitive knowledge is in fact compatible with his official definition of knowledge, and discusses his treatment of the problem of skepticism, both in the Essay and in the correspondence with Stillingfleet.

A number of philosophers have recently suggested that the role of intuitions in the epistemology of armchair philosophy has been exaggerated. This suggestion is rehearsed and endorsed. What bearing does the rejection of the centrality of intuition in armchair philosophy have on experimentalist critiques of the latter? I distinguish two very different kinds of experimentalist critique: one critique requires the centrality of intuition; the other does not.

In the recent literature on Moore's Proof of an external world, it has emerged that different diagnoses of the argument's failure are prima facie defensible. As a result, there is a sense that the appropriateness of the different verdicts on it may depend on variation in the kinds of context in which the argument is taken to be a move, with different characteristic aims. In this spirit, Martin Davies has recently explored the use of the argument within two different epistemic (...) projects called respectively ‘deciding what to believe’ and ‘settling the question’. Depending on which project is in hand, according to Davies, the diagnoses of its failure—if indeed it fails—will differ. I believe that, by introducing the idea that the effectiveness of a valid argument may be epistemic project-relative, Davies has pointed the way to an important reorientation of the debates about Moore's Proof. But I wish to take issue with much of the detail of his proposals. I argue that Davies's characterization of his two projects is misleading (§1), and his account of their distinction defective (§2). I then canvass some suggestions about how it may be improved upon and about how further relevant kinds of epistemic projects in which Moore's argument may be taken to be a move can be characterized, bringing out how each of these projects impinges differently on the issue of the Proof's failure and of its diagnosis (§§3 and 4). In conclusion (§5) I offer an overview of the resulting terrain. (shrink)

The sceptic about the external world presents us with a paradox: an apparently acceptable argument for an apparently unacceptable conclusion—that we do not know anything about the external world. Some paradoxes, for instance the liar and the sorites, are very hard. The defense of a purported solution to either of these two inevitably deploys the latest in high-tech philosophical weaponry. On the other hand, some paradoxes are not at all hard, and may be resolved without much fuss. They do not (...) contain profound lessons about the human condition. Where should we place the sceptical paradoxes? (shrink)

We offer an overview of what we take to be the main themes in Annalisa Coliva’s book, Moore and Wittgenstein: Scepticism, Certainty and Common Sense. In particular, we focus on the ‘framework reading’ that she offers of Wittgenstein’s On Certainty and its anti-sceptical implications. While broadly agreeing with the proposal that Coliva puts forward on this score, we do suggest one important supplementation to the view—viz., that this way of dealing with radical scepticism needs to be augmented with an account (...) of the meta-sceptical problem which this proposal generates, which we call epistemic vertigo.

There are two epistemological problems connected with dreaming, which are of different kinds and require different treatment. The internal problem is best seen as a problem of rational consistency, of how we can maintain all of: Dreams are experiences we have during sleep. Dream-experiences are sufficiently similar to waking experiences for the subject to be able to mistake them for waking experiences. We can tell that we are awake. (1)-(3) threaten to violate a requirement on discrimination: that we can only (...) tell Xs from Ys if there is some detectable difference between Xs and Ys. Attempts to solve the problem by Descartes and Williams are considered. It is suggested that if we take account of levels of epistemic risk, we can use Descartes's criterion of lack of coherence, at least with hindsight - which is the time when we need to use it.

This paper comprises a defence of Infallibilism about knowledge. In it, I articulate two arguments in favour of Infallibilism, and for each argument show that Infallibilism about knowledge does not lead to an unpalatable Scepticism if justified belief is neither necessary nor sufficient for knowledge, and if Fallibilism about justified belief is true.

When is a belief or judgment justified? One might be forgiven for thinking the search for single answer to this question to be hopeless. The concept of justification is required to fulfil several tasks: to evaluate beliefs epistemically, to fill in the gap between truth and knowledge, to describe the virtuous organization of one’s beliefs, to describe the relationship between evidence and theory (and thus relate to confirmation and probabilification). While some of these may be held to overlap, the prospects (...) for fulfilling all may well seem poor. Furthermore the internalist requires that justification be an introspectible property of beliefs and a fundamental epistemic concept, while the externalist is often happy to ignore the concept altogether or at best regard it as an embarrassing add-on to their epistemology. In the light of this one might reasonably give up on justification altogether or adopt pluralist approach, denying that justification is any single property of beliefs of judgments. (shrink)

The notion of a non-sensory mental state or event that plays a prominent role in coming to understand, an epistemic achievement distinct from mere knowledge, featured prominently in historical writings on philosophy, and philosophical methodology. It is, however, completely absent from contemporary discussions of the subject. This paper argues that intuition plays an epistemic role in understanding, including philosophical understanding, and offers an explanation of how intuition manages to play this role, if and when it does. It is argued, subsequently, (...) that this role is autonomous, in the sense that a source of understanding cannot be reduced to a source of justification, evidence, or reason. Finally, it is noted that such autonomy implies that popular forms of skepticism about intuition do not impugn intuition’s epistemic significance with respect to its status as a source of understanding.

Logical realism is the metaphysical view asserting that the facts of logic exist and are mind-and-language independent. McSweeney argues that if logical realism is true, we encounter a dilemma. Either we cannot determine which of the two logically equivalent theories holds a fundamental status, or neither theory can be considered fundamental. These two conclusions together constitute what is known as the Unfamiliarity Dilemma, which poses significant challenges to our understanding of the epistemological and metaphysical features of logic. In this article, (...) I present two strategies to address McSweeney’s dilemma. If these arguments prove effective, they would demonstrate that our knowledge of logic is not susceptible to the skeptical concerns raised by McSweeney’s hypothesis. (shrink)

In this article, I reply to Juli Eflin's “Epistemic Presuppositions and Their Consequences.” I query Eflin's construal of the aims, scope and method of traditional epistemology, and go on to evaluate several of the central characteristics of Eflin's positive account – pluralistic virtue epistemology.

Consider the argument: Circus-1 Men in clown suits are handing out tickets. So, probably: Circus-2 There’s a circus in town. So: Circus-3 There’s an entertainment venue in town. Presumably you’d be able to warrantedly believe Circus-2 on the basis of Circus-1. And we can suppose you’re reasonably certain that wherever there are circuses, there are entertainment venues. So you’d seem to be in a position to reasonably go on to infer Circus-3.

In On Certainty, Wittgenstein formulates several criticisms against skepticism about our knowledge of the external world. My goal is to show that Wittgenstein does not here offer a convincing answer to the skeptical problem. First, I will present a strong version of the problem, understanding it as a paradoxical argument. In the second part, I will introduce and raise problems for two pragmatic responses against skepticism that appear in On Certainty. Finally, I will present some of Wittgenstein’s logical criticisms against (...) skepticism, which may initially be considered strong, because they seem to refute some skeptical assumptions. They concern Wittgenstein’s ideas that it is logically impossible to doubt and to be mistaken about Moorean propositions, and that these propositions don’t have a truth-value. But even these, I intend to show, do not really challenge skepticism, for they are not well grounded. (shrink)

In this essay I defend a solution to a skeptical paradox. The paradox I focus on concerns epistemic justification (rather than knowledge), and skeptical scenarios that entail that most of our ordinary beliefs about the external world are false. This familiar skeptical paradox hinges on a “closure” principle. The solution is to restrict closure, despite its first appearing as a fully general principle, so that it can no longer give rise to the paradox. This has some extra advantages. First, it (...) suggests a general strategy that provides solutions to other versions of the paradox, not just those that depend on closure. Second, it clarifies the relation between the paradox and other kinds of skeptical problem. (shrink)

ABSTRACTAn undemanding claim ϕ sometimes implies, or seems to, a more demanding one ψ. Some have posited, to explain this, a confusion between ϕ and ϕ*, an analogue of ϕ that does not imply ψ. If-thenists take ϕ* to be If ψ then ϕ. Incrementalism is the form of if-thenism that construes If ψ then ϕ as the surplus content of ϕ over ψ. The paper argues that it is the only form of if-thenism that stands a chance of being (...) correct. (shrink)

This paper offers a new interpretation of Kant's relationship with skepticism in the Groundwork for the Metaphysics of Morals. My position differs from commonly held views in the literature in two ways. On the one hand, I argue that Kant's relationship with skepticism is active and systematic (contrary to Hill, Wood, Rawls, Timmermann, and Allison). On the other hand, I argue that the kind of skepticism Kant is interested in does not speak to the philosophical tradition in any straightforward sense (...) (contrary to Forster and Guyer). On my reading, Kant takes up a skeptical method in the Groundwork as a way of exposing certain obstacles in our ordinary and philosophical thinking about morality. The central obstacle he is interested in is practical in character, arising from a natural tendency we have to rationalize against the moral law. In attempting to resolve this tendency, I argue, the Groundwork turns out to have a profoundly educative task. (shrink)

Crispin Wright’s “Unified Strategy” for addressing some familiar sceptical paradoxes exploits a subtle distinction between two different ways in which we can be related to a proposition: (full-blown) belief and (mere) acceptance. The importance of the distinction for his strategy stems from his conviction that we cannot acquire any kind of evidence, either empirical or a priori, for the “cornerstones” of our cognitive projects, i.e., for those basic presuppositions of our inquiries that we must be warranted to endorse if we (...) are to claim warrant for any of the beliefs formed as a result of such inquiries: regarding the idea of a non-evidential warrant to believe a proposition as a kind of “conceptual solecism”, he doesn’t set himself the task of showing that we are evidentially warranted to believe such presuppositions, but only that of showing that we are non-evidentially warranted to accept them. In the present paper, I argue that such choice involves a fatal departure from a basic principle governing doxastic commitment—a principle that requires that we regard cornerstones propositions as propositions we are rationally committed to believe, not just entitled to accept. I press the point by presenting the Acceptance Argument, a sceptical paradox whose consideration leads to the conclusion that the Unified Strategy is caught between the Scylla of incoherently invoking a rather dubious form of epistemic alchemy and the Charybdis of placing an unexpected and apparently ad hoc restriction on the doxastic commitments we undertake by believing the things we believe. My final suggestion is that the Unified Strategy might be spared this dilemma only by undergoing a rather radical revision—a revision that would require setting aside the distinction between belief and acceptance to re-conceptualise its goal unabashedly in terms of (non-evidentially) warranted belief.

If it works, I can use Putnam’s vat argument to show that I have not always been a brain-in-a-vat. It is widely thought that the vat argument is of no use against closure scepticism – that is, scepticism motivated by arguments that appeal to a closure principle. This is because, even if I can use the vat argument to show that I have not always been a BIV, I cannot use it to show that I was not recently envatted, and (...) it is thought that the claim that I am not justified in thinking that I was not recently envatted is all that the closure sceptic requires. In this paper I first argue that scenarios in which I have been recently envatted are inadequate for the sceptic’s purposes, and so the standard argument that the vat argument is of no use against closure scepticism fails. I then argue that it is not possible to revise the standard argument to meet my objection. I conclude that, if it works, I can use the vat argument as a defence against closure scepticism. (shrink)

I will be arguing that a subject’s belief that p is justified if and only if he knows that p: justification is knowledge. I will start by describing two broad classes of allegedly justified beliefs that do not constitute knowledge and which, hence, cannot be what they are often taken to be if my view is correct. It is far from clear what my view is until I say a lot more about the relevant concept or concepts of justification that (...) concern me. The following section describes several concepts of justification that epistemologists have employed, and, in particular, identifies the two concepts of justification that I claim are coextensive with the concept of knowledge. One of those is the deontological conception of justification: I will be arguing that one ought not believe that p unless one knows that p. I imagine that the major opposition to my view will be that it is simply obvious that there are justified false beliefs, a feeling that I try to dispel in the lengthy section on concepts of justification before I finally get around to giving the main arguments in favor of my view. A view as unorthodox as mine demands more than a single argument: I offer four in the third section. Everyone allows that many people have many unjustified beliefs, and everyone has some unjustified beliefs, but such beliefs appear to be far more prevalent on my view than on more orthodox views. In the last section, I argue that unjustified beliefs, although widespread, are not quite as common as they might appear to be on my view. (shrink)

Sometimes we get what seem to be good reasons for believing that we’ve misevaluated our evidence for a proposition P. In those cases, can we use our evidence for P itself to show that we haven’t misevaluated our evidence for P? I show why doing so appears to employ viciously circular reasoning. However, I then argue that this appearance is illusory in certain cases and that we sometimes can legitimately reason in that way. This claim sheds new light on the (...) nature of epistemic undermining and epistemic circularity. In addition, it has implications for the current debate about the epistemic significance of disagreement. An important and influential position in that debate says that disagreement with others dramatically undermines our justification for a wide range of our opinions (e.g., political, religious, moral, economic, and philosophical opinions). My view on undermining and circularity implies that this position on disagreement rests on a mistake. (shrink)

This paper contributes to the current debate about radical scepticism and the structure of warrant. After a presentation of the standard version of the radical sceptic’s challenge, both in its barest and its more refined form, three anti-sceptical responses, and their respective commitments, are being identified: the Dogmatist response, the Conservativist response and the Dretskean response. It is then argued that both the Dretskean and the Conservativist are right that the anti-sceptical hypothesis cannot inherit any perceptual warrants from ordinary propositions (...) about the environment—and so the Dogmatist response founders. However, if this is so Epistemic Closure lacks any clear rationale. There is therefore good reason to agree with both the Dretskean and the Dogmatist that perceptual warrants for ordinary propositions about the environment are enough in order for those propositions to enjoy a positive epistemic status—and so the Conservativist response founders. However, the Conservativist is nonetheless right that a warrant for the anti-sceptical hypothesis is needed. For contrary to what much of the recent literature suggests, the radical sceptic need not appeal to Epistemic Closure in order to cast doubt on the legitimacy of our beliefs in ordinary propositions about the environment: there is a Pyrrhonian version of scepticism that, though equally radical, is consistent with failure of Epistemic Closure. For this reason, the Dretskean response is insufficient to answer scepticism. (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)

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.

Genia Schönbaumsfeld has recently argued for the view that our ordinary perceptual reasons provide support for heavyweight metaphysical and epistemological views, such as that there is a mind-independent physical world. Call this the Heavyweight Reasons Thesis. In this paper, I argue that we should reject the Heavyweight Reasons Thesis. I also argue that the rejection of the Heavyweight Reasons Thesis is compatible with the Factive Perceptual Reasons Thesis, the thesis that our perceptual reasons for our ordinary beliefs can be factive, (...) but that factive reasons aren’t necessarily better reasons than subjectively indiscriminable non-factive reasons.

Something about this argument sounds funny. As we’ll see, though, it takes some care to identify exactly what Moore has done wrong. Iwill assume that Moore knows premise (2) to be true. One could inquire into how he knows it, and whether that knowledge can be defeated; but Iwon’t. I’ll focus instead on what epistemic relations Moore has to premise (1) and to his conclusion (3). It may matter which epistemic relations we choose to consider. Some philosophers will diagnose Moore’s (...) argument using Contextualist machinery. They’ll say. (shrink)

One of the key debates in contemporary epistemology is that between Crispin Wright and John McDowell on the topic of radical scepticism. Whereas both of them endorse a form of epistemic internalism, the very different internalist conceptions of perceptual knowledge that they offer lead them to draw radically different conclusions when it comes to the sceptical problem. The aim of this paper is to maintain that McDowell's view, at least when suitably supplemented with further argumentation (argumentation that he may or (...) may not agree with), can be shown to be a viable alternative to Wright's anti-sceptical proposal, one that retains the driving motivation behind Wright's proposal while avoiding one of its most fundamental problems. Wright's wholesale rejection of the McDowellian anti-sceptical strategy is thus premature. (shrink)

A certain interpretation of Wittgenstein’s remarks in On Certaintyadvanced by such figures as Hilary Putnam, Peter Strawson, Avrum Stroll and Crispin Wrighthas become common currency in the recent literature. In particular, this reading focuses upon the supposed anti-sceptical import of the Wittgensteinian notion of a “hinge” proposition. In this paper it is argued that this interpretation is flawed both on the grounds that there is insufficient textual support for this reading and that, in any case, it leads to unpalatable philosophical (...) problems. Moreover, it is claimed that the popularity of this construal of On Certainty in the contemporary debate reflects an implicit commitment to the contentious doctrine of epistemological internalism. Nevertheless, it is argued that, suitably modified along the epistemologically externalist lines suggested by Michael Williams, one might be able to resurrect a viable anti-sceptical hinge proposition thesis. Furthermore, it is claimed that such a conception of the notion also receives some, albeit inconclusive, textual support from On Certainty. (shrink)

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.

Perhaps the most dominant anti‐sceptical proposal in recent literature –advanced by such figures as Stewart Cohen, Keith DeRose and David Lewis –is the contextualist response to radical scepticism. Central to the contextualist thesis is the claim that, unlike other non‐contextualist anti‐sceptical theories, contextualism offers a dissolution of the sceptical paradox that respects our common sense epistemological intuitions. Taking DeRose's view as representative of the contextualist position, it is argued that instead of offering us an intuitive response to scepticism, contextualism is (...) actually committed to a revisionist stance as regards our everyday usage of epistemic terms. In particular, it is argued that the thesis fails to present a satisfactory explication of a notion –that of‘epistemic descent’– that is pivotal to the anti‐sceptical import of the account. On the positive side, however, it is claimed that although the contextualist response to scepticism is ultimately unsatisfying, DeRose's theory does contain within it the framework for a completely different ‐ and far more persuasive ‐ account of the‘phenomenology’of scepticism which runs along non‐contextualist lines.

_ Source: _Page Count 14 One common problem with anti-skepticism and skepticism alike is their failure to account for our sometimes conflicting epistemic intuitions. In order to address this problem and provide a new direction for solving the skeptical puzzle, I consider a modified version of the puzzle that is based on knowledge claims about appearances and does not result in a paradox. I conclude that combining the elements of both the original and modified puzzle can potentially guide us towards (...) solutions that can fully explain the conflict of epistemic intuitions. (shrink)

The skeptical Dream argument appeals to the possibility of dreaming. The skeptic holds that states of being awake are subjectively indistinguishable from possible dream states and that this means that we do not know that we are awake. This, the skeptic then claims, means that we have to accept that we do not have external world knowledge.It is natural to assume that there must be a connection between the Dream argument and epistemic internalism, the view that a belief is justified (...) for a given person if and only if the person has cognitive access to all the factors that are needed for the belief to be justified. The problem, the skeptic thinks, is that in order for my belief that I am awake to be justified I have to have cognitive access to something that establishes that I am awake. But according to the skeptic, even if I am awake, this is not something I have cognitive access to. However, the more precise connections between internalism and the skeptical argument are not so clear. (shrink)

The paper argues that there is such a thing as luck in acquisition of candidate a priori beliefs and knowledge, and that the possibility of luck in this “armchair” domain shows that definitions of believing by luck that p offered in literature are inadequate, since they mostly rely on the possibility of it being the case that not- p. When p is necessary, such a definition should be supplemented by one pointing to variation in belief, not in the fact believed. (...) Thus the paper suggests a focus upon the agent and her epistemic virtue in the account of epistemic luck in general. (shrink)

I argue that a version of the so-called KK principle is true for principled epistemic reasons; and that this does not entail access internalism, as is commonly supposed, but is consistent with a broad spectrum of epistemological views. The version of the principle I defend states that, given certain normal conditions, knowing p entails being in a position to know that you know p. My argument for the principle proceeds from reflection on what it would take to know that you (...) know something, rather than from reflection on the conditions for knowledge generally. Knowing that you know p, it emerges, is importantly similar to cases of psychological self-knowledge like knowing that you believe p: it does not require any grounds other than your grounds for believing p itself. In so arguing, I do not rely on any general account of knowledge, but only on certain plausible and widely accepted epistemological assumptions. (shrink)

Stewart Cohen considers a case where his son wants a red table for his room. Cohen and his son go to the furniture store. Cohen’s son is concerned that the table his father is considering purchasing, which appears red, may in fact be white with red lights shining on it. Cohen responds with the following reasoning: The table looks red. The table is red. If the table is red, then it is not white with red lights shining on it. The (...) table is not white with red lights shining on it. If one reasons thus, say one’s engaged in -reasoning. Cohen finds such a response unsatisfactory. It is not a way of coming to know —it is too easy. And structurally similar reasoning delivers the falsity of sceptical hypotheses concerning the external world, testimony, other minds etc. So the unsatisfactoriness threatens to generalise. I consider Martin Davies ’s attempt to diagnose this unsatisfactoriness and find it incomplete. I then attempt to remedy the incompleteness in Davies ’s attempt. (shrink)
