In this article I develop Heidegger's phenomenology of poetry, showing that it may provide grounds for rejecting claims that he lapses into linguistic idealism. Proceeding via an analysis of the three concepts of language operative in the philosopher's work, I demonstrate how poetic language challenges language's designative and world-disclosive functions. The experience with poetic language, which disrupts Dasein's absorption by emerging out of equipmentality in the mode of the broken tool, brings Dasein to wonder at the world's existence in such (...) a way that doubt about its reality cannot enter the picture.

Inferential internalism holds that for one to be inferentially justified in believing P on the basis of E one must be justified in believing that E makes probable P. Inferential internalism has long been accused of generating a vicious regress on inferential justification that has drastic skeptical consequences. However, recently Hookway and Rhoda have defended a more modest form of internalism that avoids this problem. They propose a form of weak inferential internalism according to which internalist conditions are restricted to (...) only certain kinds of inferential justification. In this paper, I clarify and argue against weak internalism. I contend that while weak internalism avoids the vicious regress, it does so at the cost of compromising its internalist credentials. For I show that unless weak internalism makes an arbitrary distinction between individuals who believe for the very same reasons, the view collapses into externalism. (shrink)

Two strikingly similar critiques of epistemological foundationalism are examined: J. L. Austin's critique of A. J. Ayer in the former's "Sense and Sensibilia," and part of Candrakīrti's critique of Dignāga in the first chapter of the "Prasannapadā." With respect to Austin, it is argued that his writings on epistemology in fact relate quite closely to his better-known philosophy of speech acts, and that the appeal to ordinary language is part of a transcendental argument against the possibility of radical skepticism. It (...) is then argued that Candrakīrti makes some very similar moves, and that his argument against Dignāga makes still clearer the sense in which both Austin and Candrakīrti can be characterized as making transcendental arguments. In particular, if a condition of the possibility of meaningful discourse is the making of certain kinds of assents, then the epistemologist's demand for the justification of those assents is unreasonable.

Most solutions to the skeptical paradox about justified belief assume closure for justification, since the rejection of closure is widely regarded as a non-starter. I argue that the rejection of closure is not a non-starter, and that its problems are no greater than the problems associated with the more standard anti-skeptical strategies. I do this by sketching a simple version of the unpopular strategy and rebutting the three best objections to it. The general upshot for theories of justification is that (...) it is not a constraint on such theories that we must somehow have justification to believe that we are not massively deceived. (shrink)

A well known skeptical paradox rests on the claim that we lack warrant to believe that we are not brains in a vat (BIVs). The argument for that claim is the apparent impossibility of any evidence or argument that we are not BIVs. Many contemporary philosophers resist this argument by insisting that we have a sort of warrant for believing that we are not BIVs that does not require having any evidence or argument. I call this view ‘New Rationalism’. I (...) argue that New Rationalists are committed to there being some evidence or argument for believing that we are not BIVs anyway. Therefore, New Rationalism, since its appeal is that it purportedly avoids the problematic commitment to such evidence or argument, undermines its own appeal. We cannot avoid the difficult work of coming up with evidence or argument by positing some permissive sort of warrant. (shrink)

This article is a response to an important objection that Sherrilyn Roush has made to the standard closure-based argument for skepticism, an argument that has been studied over the past couple of decades. If Roush's objection is on the mark, then this would be a quite significant finding. We argue that her objection fails.

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.

Today we find philosophical naturalists and Christian theists both expressing an interest in virtue epistemology, while starting out from vastly different assumptions. What can be done to increase fruitful dialogue among these divergent groups of virtue-theoretic thinkers? The primary aim of this paper is to uncover more substantial common ground for dialogue by wielding a double-edged critique of certain assumptions shared by `scientific' and `theistic' externalisms, assumptions that undermine proper attention to epistemic agency and responsibility. I employ a responsibilist virtue (...) epistemology to this end, utilizing it most extensively in critique of Alvin Plantinga’s Warranted Christian Belief (2000). Epistemological externalism presages, I also argue, a new demarcation problem, but a secondary aim of the paper is to suggest reasons to think that `responsibilist externalism,' especially as glossed in virtue-theoretic terms, provides its proponents with the ability to adequately address this problem as we find it represented in a potent thought-experiment developed by Barry Stroud.

To improve our methods of rational inquiry and decision-making we need to recognize that such methods should guide but not fully determine the choices of individuals. Failure to acknowledge the essential incompleteness of rational methods made the methods of Classical Rationalism quite impractical and opened them to skeptical refutation. Mitigated Skepticism and Fideism failed to correct the error, and as a result put undesirable limits on rational inquiry. When the guiding character of rational methods is recognized, existing methods of scientific (...) research of personal and social decision-making can themselves be rationally assessed and improved. Viewing rational methods as guides thus opens a whole field of inquiry, the inquiry into what rational methods are most useful for specific purposes and in specific situations. (shrink)

It is argued that contrary to appearances, Berkeleyan Idealism lacks anti-sceptical force. The problem stems from the way in which the idealist draws the appearance/reality distinction.

The guiding questions of this volume are: Can we have knowledge of the external world of things outside our minds?

Michael Williams believes that scepticism about the externalworld seems compelling only because the considerations that underpin it are thoughtto be ``mere platitudes'''' about e.g., the nature and source of human knowledge, and hence,that if it shown through a ``theoretical diagnosis'''' that it does not rest upon suchplatitudes, but contentious theoretical considerations that we are no means bound toaccept, we can simply dismiss the absurd sceptical conclusion. Williams argues thatscepticism does presuppose two extremely contentious doctrines, however, he admits thatif (...) these doctrines are themselves motivated by ``platitudes'''' then scepticism follows. Iaddress Williams''s arguments for thinking scepticism must presuppose these doctrines,and argue that he overlooks a way that they can be seen as motivated by mere platitudes.Thus, I conclude that William''s novel rejection of scepticism fails.

In the preceding pages, Husserl's objections to the content of Descartes'Meditations on First Philosophy have been reconstructed over the line ofargument in that work. The tone of his interpretation moved from ambivalence to outfight rejection. Husserl's ambivalence manifested itself intwo of the three meditations to which he pays significant attention. We sawthe much heralded methodological strategy of the First Meditation, uponclose examination, is not endorsed by Husserl, that he finds reason toprotest (...) against the content of each individual skeptical argument and seesthere in general a subjectivistic doctrine of consciousness already at work.Nevertheless, Husserl clearly wanted to preserve the essential intent of theCartesian method of doubt if not its letter, namely, the move toward callinginto question naive presuppositions about the world, raising the possibilityof its non-existence, thereby resuscitating sheer wonder about the world,and rendering it problematic in its relation to subjectivity. Historically, thisstrategy has precedent in the ancient Greek sophists, who, however unintentionally, Husserl claims were the first to manifest a transcendental im-pulse. Moving into the Second Meditation and the so-called discovery ofthe ego cogito, we found a stronger ambivalence on Husserl's part. Whileapplauding Descartes for uncovering the truth that lay hidden at the basis ofskepticism, the subsequent interpretation of the ego as soul and substantialentity clouds this inchoative insight into pure transcendental subjectivity.By the Third Meditation Husserl's ambivalence moved to out right rejection. There are a number of reasons why: the circularity of Descartes'theological theory of evidence (Hua VII, 341); the epistemologicalcommitment to a subjectivistic theory of consciousness; hisScheinprobleme (Hua VII, 73) along with the assumption of an objectivein-itself forever remote from intuition; the ontological commitment to twofinite substances; and the attempt to deductively redress the cognitiveschism created by these commitments through appeal to the principle ofcausality and the goodness of God. All these gave Husserl decisive occa-sion to take leave of the Cartesian path of meditation.A further reason why Husserl's meditations consistently break off in theThird Meditation is suggested by noticing the textual moment whereHusserl's silence begins. It is that moment where Descartes dips into theScholastic tradition for the concepts of objective and formal reality in orderto prove the existence of God. The problem, I suggest, is that here Des-cartes insufferably compromises his radicalness. More specifically, with theconcepts of objective and formal reality Descartes installs on the metaphysi-cal level the distinction between image and original already operative allalong in the earlier Meditations. Now, through the concepts of objective andformal reality, the image(effect)/original(cause) distinction is given ex-planatory power and raised to a truth so evident as to be beyond the reach ofmethodic doubt. The fact that this distinction is employed to deduce theexistence of God is not so much the phenomenological offense as themetaphysical naivete of positing a formal reality, an in itself, to account forthe very matters in question.

The skepticism I propose to discuss concerns the reality of an external world of perceivable material objects. There are three questions our skeptic may ask. The first is nonmodal and nonepistemic: Are some of the objects we perceive real? The second is also nonmodal but epistemic: Do we know, or at least have evidence, that some of the objects we perceive are real? The third is both modal and epistemic: Can we know, or at least have evidence, that some of (...) the objects we perceive are real? By definition, the epistemic questions are the ones the skeptic asks. But I shall take the first, the nonepistemic question as primary; it is, surely, also the one in which we, including the skeptic, are really interested. The traditional approach to skepticism has been to take it as asking one or both of the epistemic questions. I suggest that.. (shrink)

One of the most important and perennially debated philosophical questions is whether we can have knowledge of the external world. Butchvarov here considers whether and how skepticism with regard to such knowledge can be refuted or at least answered. He argues that only a direct realist view of perception has any hope of providing a compelling response to the skeptic and introduces the radical innovation that the direct object of perceptual, and even dreaming and hallucinatory, experience is always a material (...) object, but not necessarily one that actually exists. This leads him to a metaphysics in which reality is ultimately constructed by human decisions out of objects that are ontologically more basic but which cannot be said in themselves to be either real or unreal.

Strawson's philosophical attitude towards scepticism is frequently thought to have undergone a significant shift from the “strong” or “robust” employment of transcendental arguments in Individuals to a more “modest” understanding of the efficacy of such arguments in Skepticism and Naturalism: Some Varieties. I argue that this interpretation is based upon a misunderstanding of the function of transcendental arguments in Strawson's earlier works. Examining the continuity of Strawson's modest naturalistic approach to scepticism can offer some insight as to the continuing overestimation (...) of the anti-sceptical efficacy of transcendental arguments. (shrink)

One skeptical strategy against A's claim to know that P is to hold that it is logically possible for someone to have the same "base" (a term needing explaining) for P as A does in spite of its not being true that P. Philosophical replies have focussed on showing that these are not genuine possibilities. Whether they are can be an interesting question of metaphysics, but it is argued in this paper that this metaphysical discussion is not the proper focus (...) for an assessment of skepticism. Even if there are the odd logical possibilities, they do not suffice to warrant skeptical doubts. Rather, there has to be good reason to think that there is a genuine chance of the alleged possibility obtaining. This requirement cannot be satisfied generically, and that is what is wrong with generic skepticism. (shrink)

These lectures by one of the most influential and original philosophers of the twentieth century constitute a sustained argument for the philosophical basis of romanticism, particularly in its American rendering. Through his examination of such authors as Emerson, Thoreau, Poe, Wordsworth, and Coleridge, Stanley Cavell shows that romanticism and American transcendentalism represent a serious philosophical response to the challenge of skepticism that underlies the writings of Wittgenstein and Austin on ordinary language.

Descartes refuted skepticism in 1641. George Berkeley refuted skepticism in 1710. O.K. Bouwsma refuted skepticism in 1949. Hilary Putnam refuted skepticism in 1981. The locus classicus for the form of skepticism refuted is Descartes' Meditations -- which also goes on to set out a famous realist refutation of skepticism. Indeed, Descartes is the principal inventor of the philosophic enterprise of skepticism refutation so central to Modern philosophy and its epistemic preoccupations. What the cited successors of Descartes and many others have (...) in common is a rejection of both skepticism and Descartes' refutation of it. Berkeley, Bouwsma and Putnam offer a sophisticated, undercutting, refutation which undermines the very coherence of skepticism. And for all, issues of language and meaning rise to the fore, determining the coherence of any skeptical doubts and constraining the possibilities of systematic error and deception (for Berkeley, these appear as issues about the objects of thought, which in turn are the foundation of the meaning of language).

Recently, new life has been breathed into the ancient philosophical topic of skepticism. The subject of some of the best and most provocative work in contemporary philosophy, skepticism has been addressed not only by top epistemologists but also by several of the world's finest philosophers who are most known for their work in other areas of the discipline. Skepticism: A Contemporary Reader brings together the most important recent contributions to the discussion of skepticism. Covering major approaches to the skeptical problem, (...) it features essays by Anthony Brueckner, Keith DeRose, Fred Dretske, Graeme Forbes, Christopher Hill, David Lewis, Thomas Nagel, Robert Nozick, Hilary Putnam, Ernest Sosa, Gail Stine, Barry Stroud, Peter Unger, and Ted Warfield. The book opens with a thorough introduction that outlines the skeptical problem, explains the dominant responses to skepticism, and discusses the strengths, weaknesses, and unresolved issues of each response, providing undergraduate students and nonphilosophers with the background and context necessary to understand the essays. Skepticism: A Contemporary Reader serves as an ideal text for courses in epistemology and skepticism and will also appeal to professional philosophers and interested general readers. (shrink)

The model-theoretic argument known as Putnam´s paradox threatens our notion of truth with triviality: Almost any world can satisfy almost any theory. Formal argument and intuition are at odds. David Lewis devised a solution according to which the very stucture of the world fixes how it is to be divided into elite classes which determine the reference of any true theory. Three claims are defended: Firstly, Lewis´ proposal must be completed by an account of successful referential intentions. Secondly, contrary to (...) Catherine Elgin´s criticism of Lewis, natural properties corresponding to elite classes may play a role in sound scientific inquiry. Thirdly, despite Bas van Fraassen´s objection that the sceptic cannot consistently maintain doubts about reference, there is a promising sceptical strategy of exploiting Putnam´s results which is answered by Lewis´ account.

External world skeptics are typically opposed to admitting as evidence anything that goes beyond the purely phenomenal, and equally typically, they disown the use of rules of inference that might enable one to move from premises about the phenomenal alone to a conclusion about the external world. This seems to bar any a posteriori resolution of the skepticism debate. This paper argues that the situation is not quite so hopeless, and that an a posteriori resolution of the debate becomes possible (...) once it is recognized that the skeptic holds overly defensive and ill-motivated positions vis-à-vis both evidence and inference, and that more reasonable ones are available. In stating these more reasonable positions, as well as in showing how they make possible an a posteriori resolution of the skepticism debate, the paper draws on the machinery of Bayesian epistemology.

Unger (1974/2000) presents an argument for skepticism that significantly differs from the more traditional arguments for skepticism. The argument is based on two premises, to wit, that knowledge would entitle the knower to absolute certainty, and that an attitude of absolute certainty is always inadmissible from an epistemic viewpoint. The present paper scrutinizes the arguments that Unger provides in support of these premises and shows that none of them is tenable. It thus concludes that Unger's argument for skepticism fails to (...) threaten the possibility of knowledge. (shrink)

It is nowadays taken for granted that the core radical sceptical arguments all pivot upon the principle that the epistemic operator in question is 'closed' under known entailments. Accordingly, the standard anti-sceptical project now involves either denying closure or retaining closure by amending how one understands other elements of the sceptical argument. However, there are epistemic principles available to the sceptic which are logically weaker than closure but achieve the same result. Accordingly the contemporary debate fails to engage with the (...) sceptical problem in its strongest form. (shrink)

In previous work I argued that skepticism about the compatibility ofanti-individualism with self-knowledge is incoherent. Anthony Brueckner isnot convinced by my argument, for reasons he has recently explained inprint. One premise in Brueckner's reasoning is that a person'sself-knowledge is confined to what she can derive solely from herfirst-person experiences of using her sentences. I argue that Brueckner'sacceptance of this premise undermines another part of his reasoning – hisattempt to justify his claims about what thoughts our sincere utterances ofcertain sentences would (...) express in various possible worlds. I describe aweird possible world in which a person who uses Brueckner's reasoning endsup with false beliefs about what thoughts her sincere utterances of certainsentences would express in various possible worlds. I recommend that wereject Brueckner's problematic conception of self-knowledge, and adopt onethat better fits the way we actually ascribe self-knowledge. (shrink)

Empirical knowledge exists in the form of antiskeptical conditionals, which are propositions like [if I am not undetectably deceived, then I am holding a pen]. Such conditionals, despite their trivial appearance, have the same essential content as the categorical propositions that we usually discuss, and can serve the same functions in science and practical reasoning. This paper sketches out two versions of a general response to skepticism that employs these conditionals. The first says that our ordinary knowledge attributions can safely (...) be replaced by statements using antiskeptical conditionals, which provides a way around the standard sort of skeptical argument while accepting its soundness with respect to the usual targets. The second analyzes the objects of our ordinary knowledge attributions as antiskeptical conditionals, which allows us to refute, not just evade, the skeptic's argument. Both versions compare favorably to the best-knowncurrent approaches to skepticism, including semantic contextualism. (shrink)

In Conspiracies and Lyes I aim to provide an epistemological account of testimony as one of our faculties of knowledge. I compare testimony to perception and memory. Its similarity to both these faculties is recognised. A fundamental difference is stressed: it can be rational to not accept testimony even if testimony is fulfilling its proper epistemic function because it can be rational for a speaker to not express a belief; or, as I say, it can be rational for a speaker (...) to lye. This difference in epistemic function provides the basis for a sceptical argument against testimony. Scepticism is presented as a method rather than a problem: considering how to refute the sceptical argument is taken to be a means of evaluating theories as to how testimonial beliefs are warranted. I consider two strategies for refuting scepticism and, correlatively, two accounts of how testimonial beliefs are warranted. I show these accounts to be neutral across all theories of justification that entertain the project of investigating our faculties of knowledge. A reductionist account explains the warrant supporting our testimonial beliefs in terms of our inductive ground for accepting testimony. An anti-reductionist account explains the warrant supporting our testimonial beliefs in terms of our possessing an entitlement to accept testimony. I show how both positions can be intuitively motivated. In presenting reductionism I appeal to probability theory, empirical psychology and invoke David Hume. In presenting anti-reductionism I invoke John McDowell and Tyler Burge. A refutation of scepticism is provided by a hybrid of reductionism and anti-reductionism. The hybrid is conceived as part social externalism and part individual internalism. In developing this account I provide a means of conceptualising the dynamic that exists between individual knowers and communities of knowledge. (shrink)

In response to new research into the phenomena of inattentional blindness and change- blindness, several philosophers and vision researchers have proposed a novel form of scepticism: they contend that we do not have the conscious experience that we think we have. I will show that this claim is not supported by the evidence usually cited in support of it, and I expose what I believe to be the underlying error motivating this position: the belief that consciousness is either focal (what (...) occupies the focus of attention) or non- existent. Once we appreciate the phenomenology of the periphery of attention, we see that we have the resources to place the problematic phenomena in our peripheral. (shrink)

Doxastic voluntarism maintains that we have voluntary control over our beliefs. It is generally denied by contemporary philosophers. I argue that doxastic voluntarism is true: normally, and insofar as we are rational, we are able to suspend belief and, provided we have a natural inclination to believe, we are able to rescind that suspension, and thus to choose to believe. I show that the arguments that have been offered against doxastic voluntarism fail; and that, if the denial of doxastic voluntarism (...) is part of a strategy to defeat scepticism, it is inept, because knowledge presupposes doubt.

The publication of Davidson 2001, anthologizing articles from the 1980s and 1990s, encourages reconsidering arguments contained in them. One such argument is Davidson’s omniscient-interpreter argument (‘OIA’) in Davidson 1983. The OIA allegedly establishes that it is necessary that most beliefs are true. Thus the omniscient interpreter, revived in 2001 and now 20 years old, was born to answer the skeptic. In Part I of this paper, I consider charges that the OIA establishes only that it is possible that most beliefs (...) are true; if correct, then it is also possibly the case that most beliefs are false—the skeptic’s very position. Next, I consider two responses on Davidson’s behalf, showing that each fails. In Part II, I show that the OIA establishes neither that it is necessarily merely possibly but actually the case that most beliefs are true. I then conclude that this is enough to answer the skeptic.

People see five kinds of views in epistemology and ontology as hinging on there being words a person can learn only by private ostensive definitions, through direct acquaintance with his own sensations: skepticism about other minds, 2. skepticism about an external world, 3. foundationalism, 4. dualism, and 5. phenomenalism. People think Wittgenstein refuted these views by showing, they believe, no word is learnable only by private ostensive definition. I defend these five views from Wittgenstein’s attack.

Radical skepticism about the external implies that no belief about the external is even prima facie justified. A theoretical reply to skepticism has four stages. First, show which theories of epistemic justification support skeptical doubts (show which theories, given other reasonable assumptions, entail skepticism). Second, show which theories undermine skeptical doubts (show which theories, given other reasonable assumptions, do not support the skeptic’s conclusion). Third, show which of the latter theories (which non-skeptical theory) is correct, and in so doing show (...) that all of the rival theories of justification, skeptical and non-skeptical alike, are mistaken. Fourth, explain why skeptical doubts are sometimes (or sometimes merely seem) intuitive, and thereby accommodate skeptical doubts without capitulation. Michael Williams has pioneered the very idea of a theoretical reply. A theoretical diagnosis consists in just the first two stages. An adequate reply, which is correct at each stage, would rebut the skeptic entirely. Williams’ own reply, I argue, is inadequate. I offer in its place an exhaustive and accurate diagnosis of skepticism. I distinguish four kinds of skepticism and five theories of justification. I then show which theories do, and which theories do not, support which kinds of skepticism. (shrink)

In this series of studies A. C. Grayling looks at approaches the problem of how sceptical challenges can be met.

In the history of philosophical thought, few themes loom as large as skepticism. Skepticism has been the most visible and important part of debates about knowledge. Skepticism at its most basic questions our cognitive achievements, challenges our ability to obtain reliable knowledge; casting doubt on our attempts to seek and understand the truth about everything from ethics, to other minds, religious belief, and even the underlying structure of matter and reality. Since Descartes, the defense of knowledge against skepticism has been (...) one of the primary tasks not just of epistemology but philosophy itself. The Oxford Handbook of Skepticism features twenty-six newly commissioned chapters by top figures in the field. Part One contains articles explaining important kinds of skeptical reasoning. Part Two focuses on responses to skeptical arguments. Part Three concentrates on important contemporary issues revolving around skepticism. As the first volume of its kind, the articles make significant contributions to the debate on skepticism. (shrink)

Murray G. Murphey’s masterful treatment of C. I. Lewis’s philosophy leaves two things amply clear: first, that Lewis struggled with skeptical arguments from Hume throughout his career; and second, that Lewis never adequately resolved the problems raised by those arguments. In this paper I will consider Lewis’s approach to Hume’s skepticism in Mind and the World Order (MWO) and in An Analysis of Knowledge and Valuation (AKV), and I will argue that Lewis’s reply to Hume in these works did not (...) change as dramatically as Murphey claims. Nevertheless, I agree with Murphey that there are two quite different lines of reply discernable in Lewis, and that neither adequately answers Hume. In the final part of the paper I argue that Lewis’s pragmatism gives us resources for an adequate reply to Hume’s skeptical arguments, although it is not the reply that Lewis himself gives. (shrink)

I review a familiar skeptical argument from Hume, and conclude that it requires us to accept that there is no necessary relation between beliefs about the world and their evidential grounds; that is, there is no logical or quasi-logical relation between empirical beliefs and their grounds, such that their grounds entail them, or even make them probable. I then argue that generic reliabilism can accommodate this fact about evidential grounds in a non-skeptical way. According to reliabilism, the grounds for our (...) beliefs constitute good evidence so long as they are contingently reliable. Next I argue that agent reliabilism successfully addresses two related problems for other versions of reliabilism: the fact that beliefs can be reliably formed by accident, and the need for subjective justification. Finally, I explain why agent reliabilism is properly conceived as a version of virtue epistemology. (shrink)

Must we believe in logical necessity? I examine an argument for an affirmative answer given by Ian McFetridge in his posthumously published paper 'Logical Necessity: Some Issues', and explain why it fails, as it stands, to establish his conclusion. I contend, however, that McFetridge's argument can be effectively buttressed by drawing upon another argument aimed at establishing that we ought to believe that some propositions are logically necessary, given by Crispin Wright in his paper 'Inventing Logical necessity'. My contention is (...) that Wright's argument, whilst it likewise fails, as it stands, to establish the necessity of necessity, established enough to close off what appears to me to be the only effective-looking sceptical response to McFetridge's original argument. My paper falls into four principal parts. In the first I expound McFetridge's argument and draw attention to the possibility of a certain type of sceptical counter to it. In the second, I begin a response to this sceptical move, taking it as far as I can without reliance upon argument of the kind given by Wright. Turning, then, to Wright's argument, I explain to what extent I think it is successful and seek to rebut some objections to the argument which, were they well-taken, would show that the argument cannot enjoy even the partial success I which to claim for it. Finally, I return to my main theme and try to show, with the assistance of what I take to be solidly established by Wright's argument, that the sceptical response collapses. (shrink)

The main claim of this essay is that knowledge is no more
valuable than lasting true belief.
This claim is surprising. Doesn't knowledge have a unique
and special value? If the main claim is correct and if, as it seems,
knowledge is not lasting true belief, then knowledge does not have a unique value:
in whatever way knowledge is valuable, lasting true belief is just as valuable.
However, this result does not show that knowledge is worthless, nor does it undermine
our knowledge gathering practices. There (...) is, rather, a positive philosophical payoff:
skepticism about knowledge is defused. Assuming one can have lasting true belief,
then even if one cannot have knowledge, one can have something just as valuable.

A recent article by Jeff Kochan contains a discussion of modus ponens that among other thing alleges that the paradox of the heap is a counterexample to it. In this note I show that it is the conditional major premise of a modus ponens inference, rather than the rule itself, that is impugned. This premise is the contrapositive of the inductive step in the principle of mathematical induction, confirming the widely accepted view that it is the vagueness of natural language (...) predicates, not modus ponens , that is challenged by Sorites.

"If a person can think of an F, then that person has come into causal contact with an F in the right way" is a premise in an obvious reconstruction of Putnam’s argument that we are not brains in vats. ’If a person can think of an F, then that person has come into causal contact with an F or with something at least as good as an F’ is the only controversial premise in Descartes’s argument for the existence of (...) God. Putnam’s principle entails Descartes’s, which suggests that we should enquire after better versions of Putnam’s proof. I present three variations and conclude that Putnam’s semantic theory does not have antisceptical consequences. In contrast, given Descartes’s cognitive situation, he was perfectly justified in accepting the soundness of his argument for the existence of God. (shrink)

The aim of this paper is to provide the beginnings of a theory of justification. This theory is an alternative to the two currently available and unsatisfactory options: foundationalism and coherentism. Both of these theories, as well as the decisive sceptical objections to them, are committed to the assumption that there is only one context of justification and only one standard of justification. This assumption is mistaken. There are two contexts of justification, each with a standard peculiar to it. The (...) consequence of this is the need for a radical reorientation in epistemology.

Rich with historical and cultural value, these works are published unaltered from the original University of Minnesota Press editions.

Robert Pasnau’s paper presents a strong thesis, which it does not manage to substantiate. The thesis in question is that the Aristotelian doctrine of the identity of the knower and the known, as interpreted by St. Thomas, cannot possibly be used to fend off skepticism.

Colin Howson argues that (1) my sociologistic reliabilism sheds no light on the objectivity of epistemic content, and that (2) sorites does not threaten the reliability of modus ponens . I reply that argument (1) misrepresents my position, and that argument (2) is beside the point.

Abstract: It is generally accepted that skeptical scenarios must be possible to raise legitimate skeptical doubt. I argue that if the possibility in question is supposed to be genuine metaphysical possibility, the skeptic's reasoning does not straightforwardly succeed. I first motivate the metaphysical possibility requirement on skeptical scenarios: it's a plausible position that several authors accept and that a family of prominent views—sensitivity, safety, relevant alternatives—are committed to. I argue that plausible constraints in modal epistemology show that justification for believing (...) that certain global skeptical scenarios are metaphysically possible rests on some justified beliefs about the external world, and that this undermines the skeptical argument. While there may still be local skeptical challenges, skeptics cannot appeal to the metaphysical possibility of skeptical scenarios to generate global external world skepticism. (shrink)

Duncan Pritchard’s book (Epistemic Luck, Oxford University Press, 2005) concerns the interplay between two disturbing kinds of epistemic luck, termed “reflective” and “veritic,” and two types of arguments for skepticism, one based on a closure principle for knowledge and the other on an underdetermination thesis about the quality of our evidence for the everyday propositions we believe. Pritchard defends the view that a safety-based account of knowledge can answer the closure argument and provide an account of how veritic epistemic luck (...) is eliminated. He also argues that reflective epistemic luck cannot be eliminated, and that even though it is the sort of luck with which the underdetermination argument is concerned, the fact that this type of luck cannot be eliminated doesn’t undermine knowledge. Instead, it undermines the assertibility of our knowledge, at least in skeptical contexts. So when the skeptic challenges the idea that we know using the underdetermination principle, we have no legitimate response to offer, and it is this fundamental fact of epistemic life that Pritchard terms our inevitable epistemic angst.
