In the Treatise of Human Nature , Hume argues that, because we have adequate ideas of the smallest parts of space, we can infer that space itself must conform to our representations of it. The paper examines two challenges to this argument based on Descartes's and Locke's treatments of adequate ideas, ideas that fully capture the objects they represent. The first challenge, posed by Arnauld in his Objections to the Meditations , asks how we can know that an idea is (...) adequate. The second challenge, implicit in Locke's Essay , asks how an empiricist can characterize an idea as inadequate, as both picking out an object and yet failing to capture it fully. In showing how Hume responds to these challenges, his theory of perceptual representation is explained and his treatment of space is related to his scepticism. His conclusion is shown not to be a characterization of space as it exists wholly apart from our powers of conception. Instead, in an adumbration of Kant, his claim is restricted to space as it appears to us. (shrink)

This paper asks whether we should still be haunted by scepticism about other minds. It draws on the writings of Cavell and Husserl to show that there is some truth in the Cartesian premise that has given rise to scepticism about other minds, namely, that our self-awareness is of a fundamentally different type from our awareness of objects and other subjects. While this leads Cavell to argue that there is a truth to scepticism, it proves the opposite to Husserl, viz. (...) that other minds scepticism is necessarily non-sensical. The paper shows why Husserl's position is more convincing than Cavell's. 1. (shrink)

The scandal to philosophy and human reason, wrote Kant, is that we must take the existence of material objects on mere faith . In contrast, the skeptical paradox that has scandalized recent philosophy is not formulated in terms of faith, but rather in terms of justification, warrant, and entitlement. I argue that most contemporary approaches to the paradox (both dogmatist/liberal and default/conservative) do not address the traditional problem that scandalized Kant, and that the status of having a warrant (or justification) (...) that is derived from entitlement is irrelevant to whether we take our beliefs on mere faith. For, one can have the sort of warrant that most contemporary anti-skeptics posit while still taking one’s belief on mere faith. An alternative approach to the traditional problem is sketched, one that still makes use of contemporary insights about “entitlement.”. (shrink)

This review article responds to Paul Guyer's account of the relationship between Kant and Hume, focusing in particular on the ways in which he connects questions of cognition to questions of causation.

I examine the conditions which hypotheses must satisfy if they are to be used to raise significant sceptical challenges. I argue that sceptical hypotheses do not have to be logically, metaphysically or epistemically possible: they need only to depict scenarios subjectively indistinguishable from the actual world and to show how subjects can believe what they do while not having knowledge. I also argue that sceptical challenges can be raised against a priori beliefs, even if those beliefs are necessarily true. I (...) hope to broaden our conception of the legitimate kinds of sceptical challenges which can be raised. (shrink)

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

In "Of Personal Identity,", Hume attempts to explain how one arrives at the fiction of a substantial self which retains its numerical identity through time. In "Of Scepticism with Regard to the Senses," Hume offers a similar explanation of the origin of another fiction - that of objects which enjoy a continued and distinct existence. In this paper, I will argue that his pair of parallel explanations does not jointly account for the pair of fictions to be explained.

This paper compares two kinds of epistemic principles-an underdetermination principle and a deductive closure principle. It argues that each principle provides the basis for an independently motivated skeptical argument. It examines the logical relations between the premises of the two kinds of skeptical argument and concludes that the deductive closure argument cannot be refuted without refuting the underdetermination argument. The underdetermination argument, however, can be refuted without refuting the deductive closure argument. In this respect, the deductive closure argument is the (...) stronger of the two. (shrink)

Ethnomethodology is in trouble, its conceptual apparatus prone to indifference or misunderstanding both from "conventional" sociologists and from its own practitioners. This article describes some of these loci of confusion and suggests that they have a common root in the relationship between ethnomethodology and conventional sociology. Ethnomethodologists' desire to find a principled theoretical framework for dealing with this relationship is shown to be the common basis for subsequent confusion, and some of the corollaries of their putative solution(s) are elaborated with (...) regard to their philosophical and programmatic implications. Key Words: ethnomethodology • social constructionism • situated action • social structures. (shrink)

This paper shows that the resources mobilized by recent arguments against individualism in the philosophy of mind also suffice to construct a good argument against a Humean-style skepticism about our knowledge of extra-mental reality. The argument constructed, however, will not suffice to lay to rest the attacks of a truly global skeptic who rejects the idea that we usually know what our occurrent mental states are.

Timothy Williamson's epistemology leads to a fairly radical version of scepticism. According to him, all knowledge is evidence. It follows that if S knows p, the evidential probability for S that p is 1. I explain Williamson's infallibilist account of perceptual knowledge, contrasting it with Peter Klein's, and argue that Klein's account leads to a certain problem which Williamson's can avoid. Williamson can allow that perceptual knowledge is possible and that all knowledge is evidence, while at the same time avoiding (...) Klein's problem. But while Williamson can allow that we know some things through experience, there are very many things he must say we cannot know. Given just how very many these are, he should be considered a sceptic. (shrink)

Speakers of the “green backlash” movement frequently advertise their approach as one of rigorous scepticism, and themselves as defenders of scientific method. In reality, their use of scepticism is often highly flawed and inconsistent; this is clearly seen in case examples focusing on Philip Stott's arguments on climate change, and Julian Simon's arguments on physical limits to growth. What this discourse illustrates is that sceptical language is often used as a rhetorical tool for advancing an underlying political philosophy that is (...) based on an ideal of modern science as bestower of unlimited material power. In order to understand, and to criticise this discourse effectively, one needs to recall the criticisms made by the likes of Hayek and Arendt of “scientism”—the misuse of the language of science, and its aura of predictive certainty, to portray certain political visions as being inevitably true and triumphant.

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)

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)

A naturalistic project descended from Hume seeks to explain „ought‟ and normativity as a product of motivational states such as desires and aversions.2 Following Kant, rationalists reject this thesis, holding that „ought‟ rather expresses a command of reason or intellect independent of desires. On Hume‟s view the only genuine form of practical reason is theoretical reason operating in the service of desire, as in calculation of means to ends. Reason at most discovers normative requirements, which exist through the interrelation of (...) subjective desires and objective world. The Humean desiredependence view of the source of normativity is commonly associated with instrumentalism, an influential theory of normative content according to which agents ought always and only to act so as to optimize satisfaction of their own desires. But rationalists (including Thomas Nagel, Jean Hampton, and Christine Korsgaard) have recently argued that proponents of desire-dependence are not entitled even to this instrumentalist „ought.‟3 Instrumentalism holds that all normativity derives from the instrumental norm: approximately, the principle that one ought to take the means to one‟s ends, or..

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)

The epistemological consequences of paradox are paradoxical. They can be usefully generated by telling a series of once-upon-a-time stories that make various philosophical points, starting out innocent and ending up, well, paradoxical.

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

I once overheard a telling conversation between two of my colleagues. One asked the other about a new book on a topic of some importance to both of them. He asked whether they would have to do anything different because of the book. The second colleague said not, so the first colleague said he would not read the book. The conversation encapsulates an excellent test of the worth of a philosophical work: an idea is important if as a result of (...) it experts will have to change what they do when they work on the idea’s topic. It’s not good enough to be right, or to choose an important topic, or to choose a topic of contemporary interest, or to be original; it isn’t even enough to have all of those qualities. I know now that much of the work I have done, especially as a graduate student, failed that test—even work that found its way into leading philosophy journals. (shrink)

Harry Collins' central argument about experimental practice revolves around the thesis that facts can only be generated by good instruments but good instruments can only be recognized as such if they produce facts. This is what Collins calls the experimenters' regress. For Collins, scientific controversies cannot be closed by the 'facts' themselves because there are no formal criteria independent of the outcome of the experiment that scientists can apply to decide whether an experimental apparatus works properly or not.No one seems (...) to have noticed that the debate is in fact a rehearsal of the ancient philosophical debate about skepticism. The present article suggests that the way out of radical skepticism offered by the so-called mitigated skeptics is a solution to the problem of consensus formation in science. (shrink)

Some opponents of the incommensurability thesis, such as Davidson and Rorty, have argued that the very idea of incommensurability is incoherent and that the existence of alternative and incommensurable conceptual schemes is a conceptual impossibility. If true, this refutes Kuhnian relativism and Kantian scepticism in one fell swoop. For Kuhnian relativism depends on the possibility of alternative, humanly accessible conceptual schemes that are incommensurable with one another, and the Kantian notion of a realm of unknowable things-in-themselves gives rise to the (...) possibility of humanly inaccessible schemes that are incommensurable with even our best current or future science. In what follows we argue that the possibility of incommensurability of either the Kuhnian or the Kantian variety is inescapable and that this conclusion is forced upon us by a simple consideration of what is involved in acquiring a concept. It turns out that the threats from relativism and scepticism are real, and that anyone, including Davidson himself, who has ever defended an account of concept acquisition is committed to one or the other of these two possibilities.1.

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)

This book is about the nature of skeptical arguments and their role in philosophical inquiry. John Greco delineates three main theses: that a number of historically prominent skeptical arguments make no obvious mistake, and therefore cannot be easily dismissed; that the analysis of skeptical arguments is philosophically useful and important, and should therefore have a central place in the methodology of philosophy; and that taking skeptical arguments seriously requires us to adopt an externalist, reliabilist epistemology. Greco argues that the importance (...) of skeptical arguments is methodological. It is further argued that taking skeptical arguments seriously requires us to adopt a version of 'virtue epistemology', or a theory of knowledge that makes intellectual virtue central in the analysis of knowledge. The above methodology has consequences for moral and religious epistemology; in particular, a theory of moral perception is defended. (shrink)

The first part of this article discusses recent skepticism about character traits. The second describes various forms of virtue ethics as reactions to such skepticism. The philosopher J.-P. Sartre argued in the 1940s that character traits are pretenses, a view that the sociologist E. Goffman elaborated in the 1950s. Since then social psychologists have shown that attributions of character traits tend to be inaccurate through the ignoring of situational factors. (Personality psychology has tended to concentrate on people's conceptions of personality (...) and character rather than on the accuracy of these conceptions). Similarly, the political theorist R. Hardin has argued for situational explanations of bloody social disputes in the former Yugoslavia and in Africa, rather than explanations in terms of ethnic hatred for example. A version of virtue ethics might identify virtues as characteristics of acts rather than character traits, as traits consisting in actual regularities in behavior, or as robust dispositions that would manifest themselves also in counterfactual situations.

This paper examines Honderich's attempt to make sense of the widespread view that acceptance of determinism undermines reason and knowledge. Since I am largely in sympathy with Honderich's approach to these issues, the paper develops a theme suggested by his discussion and disagrees with some details of the focus of his argument rather than challenging the general principles he employs. After introducing the issue and sketching Honderich's version of the argument from determinism to scepticism, I present an alternative which is (...) closer to traditional patterns of sceptical argument. The concluding sections compare the two arguments and the anti?determinist assumptions about agency and the self which each employs: scepticism results from determinism against the background of a conception of rationality and justification which supports a Cartesian approach to epistemology and an internalist theory of justification.

The purpose of this paper is to question some commonly accepted patterns of reasoning involving nonmonotonic logics that generate multiple extensions.

It is sometimes objected that anti-individualism, because of its assumption of the constitutive role of natural and social environments in the individuation of intentional attitudes, raises sceptical worries about first-person authority--that peculiar privilege each of us is thought to enjoy with respect to non-Socratic self-knowledge. Gary Ebbs believes that this sort of objection can be circumvented, if we give up metaphysical realism and scientific naturalism and adopt what he calls a “participant perspective” on our linguistic practices. Drawing on broadly Wittgensteinian (...) considerations, I argue that Ebbs is right about this, and I show how two likely objections to his view can be circumvented. I also argue that mere adoption of the participant perspective does not serve to refute external-world sceptic. (shrink)

Although John Stuart Mill places considerable emphasis on three information signalling devices – debate, votes and prices – he remains curiously sceptical about the prospects of institutional or social epistemology. In this paper, I explore Mill's modest scepticism about institutional epistemolog y and compare and contrast that with the attitudes of liberal theorists such as F. A. Hayek and John Dewey who are much more enthusiastic about the prospects of social epistemology as part of their defences of liberalism. The paper (...) examines the extent to which Hayek and Dewey ignore concerns originally raised by Mill. I conclude that Mill's modest scepticism is reflected in the epistemological abstinence of contemporary liberal philosophers such as John Rawls, and that his elevation of philosophy over democracy remains a challenge to contemporary defenders of the political value of social or institutional epistemology.

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.

This paper explores the possibility of resisting meaning scepticism – the thesis that there are many alternative incompatible assignments of reference to each of our terms - by appealing to the idea that the nature of reference is to maximize knowledge. If the reference relation is a knowledge maximizing-relation, then some candidate referents are privileged among the others - i.e., those referents we are in a position to know about – and a positive reason against meaning scepticism is thus individuated. (...) A knowledge-maximizing principle on the nature of reference was proposed by Williamson in a recent paper (Williamson 2005). According to Williamson, such a principle would count as a defeasible reason for thinking that most of our beliefs tend to be true. My paper reverses Williamson’s dialectic, and argues that reference is knowledge-maximizing from the premise that most of our beliefs tend to be true. (shrink)

Sub-Thesis 1: We should be contingent reliabilists to avoid the threat of an unacceptably strong content skeptical thesis posed by content externalism and the possibility of twin thoughts. The predominant strategy for resisting this threat has been to rely on the claim that introspective self-attributions are immune to brute error; but this claim is problematic from a naturalistic standpoint.

Skeptical theses in general claim that we cannot know what we think we know. Content skepticism in particular claims that we cannot know the contents of our own occurrent thoughtsat least not in the way we think we can. I argue that an externalist account of content does engender a mild form of content skepticism but that the condition is no real cause for concern. Content externalism forces us to reevaluate some of our assumptions about introspective knowledge, but it is (...) compatible with privileged access and the distinctive epistemic character of introspective judgments.

The problem of defining culture has exercised anthropologists but not cross?cultural psychologists because psychological science is based on quantitative forms of empiricism where the validity of categorical boundaries is determined by their predictive utility. Furthermore, many indigenous psychologies have been allied to nation?building projects in the developing world that choose to gloss over within state ethnic differences for the purposes of national strength and unity. Finally, Carl Martin Allwood?s target article ?On the foundation of the indigenous psychologies? (2011, Social Epistemology (...) 25 (1): 3?14) is grounded in western thinking about science that privileges analytical philosophy, particularly the importance of constructing definitional categories as the basis of its critique of indigenous psychologies. This is a limited basis for thinking about psychological science whose flaws have been exposed by highly visible critiques on analytical versus holistic thinking. From the point of view of Asian social psychologists, there is no analytical solution as to where to draw the boundaries of culture because culture is a social construction that will vary according to the situation and motives at play in different situations. But this is not an intractable problem because all human psychology is intentionally realized with elements of social construction that are part and parcel of experienced reality. (shrink)

Modern skepticism can be usefully divided into two camps: the Cartesian and the Humean.1 Cartesian skepticism is a matter of a theoretical doubt that has little or no practical import in our everyday lives. Its employment concerns whether or not we can achieve a special kind of certain knowledge – something Descartes calls “scientia” 2—that is far removed from our everyday aims or standards of epistemic appraisal. Alternatively, Humean skepticism engages the ancient skeptical concern with whether we have good reason, (...) or any reason at all, for our beliefs, including the common or garden beliefs that are presupposed in our ordinary practical affairs. On this traditional conception, philosophical doubt is a projection of everyday doubt and the lessons of the study are potentially lessons for the street. In this paper I shall focus on the Humean strain of skepticism whose focus concerns whether we have adequate reasons for our beliefs. Henceforth when I speak of skepticism it is this variety of skepticism that I am primarily referring to.3 I want to relate skepticism, so understood, to two kinds of self-knowledge. I shall argue that the failure of past solutions and dissolutions of skepticism to provide a satisfying response to the skeptic can be accounted for in terms of two stances that we can take towards our own..

This paper compares Wittgenstein's conception of ?objective certainty? with Descartes's ?metaphysical certainty?. According to both conceptions if you are certain of something in these senses, then it is inconceivable that you are mistaken. But a striking difference is that for Descartes, if you are metaphysically certain of something it follows both that the something is so and that you know it is so; whereas on Wittgenstein's conception neither thing follows. I try to show that there is a form of ?scepticism? (...) in Wittgenstein's outlook on the concept of certainty, although it is not the familiar Philosophical Scepticism. The Appendix takes issue with a recent essay by John Cook which argues that the ?hinge propositions? of On Certainty are based on ?the metaphysics of phenomenalism? (shrink)
