Some philosophers understand epistemological skepticism as merely presenting a paradox to be solved, a paradox given rise to by some apparently forceful arguments. I argue that such a view needs to be justified, and that the best way to do so is to show that we cannot help seeing skepticism as obviously false. The obviousness (to us) of the falsity of skepticism is, I suggest, explained by the fact that we cannot live without knowledge-beliefs (a knowledge-belief about the world is (...) a belief that a person or a group of people know that p, where p is an empirical proposition about the world). I then go on to argue for the indispensability of knowledge-beliefs. The first line of argument appeals to the practical aspects of our employment of the concept of knowledge, and the second line of argument draws on some Davidsonian ideas concerning understanding and massive agreement.

P. F. Strawson suggests an anti-sceptical strategy which consists in offering good reason for ignoring scepticism rather than trying to refute it, and the reason he offers is that beliefs about the external world are indispensable to us. I give an exposition of Strawson's arguments for the indispensability thesis and explain why they are not strong enough. I then propose an argument based on some of Davidson's ideas in his theory of radical interpretation, which I think can establish the indispensability (...) thesis. Finally, I spell out the force of Strawson's anti-sceptical strategy by arguing that we have good reason for ignoring scepticism not only because beliefs about the world are indispensable, but also because it is irrational to have both beliefs about the world and sceptical doubts.

A new reading of G.E. Moore's ‘Proof of an External World’ is offered, on which the Proof is understood as a unique and essential part of an anti-sceptical strategy that Moore worked out early in his career and developed in various forms, from 1909 until his death in 1958. I begin by ignoring the Proof and by developing a reading of Moore's broader response to scepticism. The bulk of the article is then devoted to understanding what role the Proof plays (...) in Moore's strategy, and how that role is played. (shrink)

Disjunctivists (Hinton 1973, Snowdon 1990, Martin 2002, 2006) often motivate their approach to perceptual experience by appealing in part to the claim that in cases of veridical perception, the subject is directly in contact with the perceived object. When I perceive a table, for example, there is no table-like sense-impression that stands as an intermediary between the table and me. Nor am I related to the table as I am to a deer when I see its footprint in the snow. (...) I do not experience the table by experiencing some- thing else over and above the table and its facing surface. I see the facing surface of the table directly. (shrink)

Many philosophers claim that interesting forms of epistemic evaluation are insensitive to truth in a very specific way. Suppose that two possible agents believe the same proposition based on the same evidence. Either both are justified or neither is; either both have good evidence for holding the belief or neither does. This does not change if, on this particular occasion, it turns out that only one of the two agents has a true belief. Epitomizing this line of thought are thought (...) experiments about radically deceived “brains in vats.” It is widely and uncritically assumed that such a brain is equally justified as its normally embodied human “twin.” This “parity” intuition is the heart of truth-insensitive theories of core epistemological properties such as justification and rationality. Rejecting the parity intuition is considered radical and revisionist. In this paper, I show that exactly the opposite is true. The parity intuition is idiosyncratic and widely rejected. A brain in a vat is not justified and has worse evidence than its normally embodied counterpart. On nearly every ordinary way of evaluating beliefs, a false belief is significantly inferior to a true belief. Of all the evaluations studied here, only blamelessness is truth-insensitive. (shrink)

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

According to factive accounts of the norm of belief and decision-making, you should not believe or base decisions on a falsehood. Even when the evidence misleadingly suggests that a false proposition is true, you should not believe it or base decisions on it. Critics claim that factive accounts are counterintuitive and badly mischaracterize our ordinary practice of evaluating beliefs and decisions. This paper reports four experiments that rigorously test the critic’s accusations and the viability of factive accounts. The results undermine (...) the accusations and provide the best evidence yet of factive norms of belief and decision-making. The results also help discriminate between two leading candidates for a factive norm: truth and knowledge. Knowledge is the superior candidate. (shrink)

This paper examines the role of ?situations? in John Dewey's philosophy of logic. To do this properly it is necessary to contrast Dewey's conception of experience and mentality with views characteristic of modern epistemology. The primary difference is that, rather than treat experience as peripheral and or external to mental functions (reason, etc.), we should treat experience as a field in and as a part of which thinking takes place. Experience in this broad sense subsumes theory and fact, hypothesis and (...) evidence, reason and observation, thought and perception. Logic in this view is a formal study of the generic features of all possible kinds of experience in this broad (thick, deep, wide, multifaceted) sense. The goal of this paper is to explain what Dewey thinks a situation is in the context of this view of experience, and to argue for the fundamental importance of that idea for logic and philosophy in general.

The basic philosophical controversy regarding ordinary objects is: Do tables and chairs, sticks and stones, exist? This paper aims to do two things: first, to explain why how this can be a controversy at all, and second, to explain why this controversy has arisen so late in the history of philosophy. Section 1 begins by discussing why the 'obvious' sensory evidence in favor of ordinary objects is not taken to be decisive. It goes on to review the standard arguments against (...) the existence of ordinary objects – including those based on problems with causal redundancy, parsimony, co-location, sorites arguments, and the special composition question. Section 2 goes on to address what it is about the contemporary approach to metaphysics that invites and sustains this kind of controversy, and helps make evident why debates about ordinary objects lead so readily to debates in metametaphysics about the nature of metaphysics itself.

This paper (1) sketches a phenomenological analysis of visual mental imagery; (2) applies this analysis to the mental imagery debate in cognitive science; (3) briefly sketches a neurophenomenological approach to mental imagery; and (4) compares the results of this discussion with Dennett’s heterophenomenology.

The main thesis of this paper is that it is not possible to determine the nature of epistemic justification apart from scientific psychological investigation. I call this view the strong thesis of methodological psychologism. Two sub-theses provide the primary support for this claim. The first sub-thesis is that no account of epistemic justification is correct which requires for the possession of at least one justified belief a psychological capacity which humans do not have. That is, the correct account of epistemic (...) justification must be psychologically realistic. The second sub-thesis is that it is not possible to determine whether an account of epistemic justification is psychologically realistic apart from scientific psychological investigation. After defending these subtheses, I point out some interesting consequences of the overall thesis which present a challenge to traditional epistemology. (shrink)

I start from Phillips' discussion of Rhees's dissatisfaction with the idea of a language‐game. Then, from a rereading of Moore, I go on to exemplify interconnected uses of the expressions “language‐game,”“recurrent procedure,”“world‐picture,”“formal procedure,”“agreement in judgment,”“genre picture” and “form of life.” The discussion is related to sense perception, our knowledge of time and space, and the picture‐theory. These topics connect with Wittgenstein's earlier treatment of the will – which changed markedly later. The subtext (in footnotes) confronts (i) the sceptical methods of (...) Descartes and Hume with the grammatical methods of Leibniz, Kant and Wittgenstein, and (ii) the realism of Leibniz and the Tractatus with the transcendental idealism of Kant. My conclusion is that, although the method of Wittgenstein's later work remains in a sense grammatical, (i) in its new form it can free us from the conviction that the intellect can and must resolve one way or the other the conflicts that arise in the course of the latter confrontation, and that (ii), although release from such a conviction is to be seen as the aim of philosophical discourse in general, it allows philosophy to retain its overriding significance. A positive element in that lies in the respect the method demands for that in a human life which is transcendental to the activity of scientific theorising: respect, therefore, for the unique perspective of the individual historical agent.

No topic in informal logic is more important than begging the question. Also, none is more subtle or complex. We cannot even begin to understand the fallacy of begging the question without getting clear about arguments, their purposes, and circularity. So I will discuss these preliminary topics first. This will clear the path to my own account of begging the question. Then I will anticipate some objections. Finally, I will apply my account to a well-known and popular response to scepticism (...) by G. E. Moore. (shrink)

A 1% skeptic is someone who has about a 99% credence in non-skeptical realism and about a 1% credence in the disjunction of all radically skeptical scenarios combined. The first half of this essay defends the epistemic rationality of 1% skepticism, appealing to dream skepticism, simulation skepticism, cosmological skepticism, and wildcard skepticism. The second half of the essay explores the practical behavioral consequences of 1% skepticism, arguing that 1% skepticism need not be behaviorally inert.

Consider the following epistemological principle:KR: A knowledge source K can yield knowledge for subject S only if S knows K is reliable.Traditional epistemologists face a dilemma: either reject KR and confront what Stewart Cohen calls “the Problem of Easy Knowledge” or embrace KR and deny that unreflective beings can possess knowledge. In order to avoid this dilemma, an epistemological theory must allow for knowledge on the part of unreflective beings without falling prey to the problem of easy knowledge. I argue (...) that the epistemology of the dying Wittgenstein, presented posthumously in On Certainty, avoids the dilemma. (shrink)

In this article I construe Russell's definite description notation as a fragment of an "ideal language"– a language in which, as Russell puts it in the "Logical Atomism" lectures, "the words in a proposition correspond one by one with the components of the corresponding fact." Russell's notation – containing as it does variables, quantifiers and the identity sign – commits him to an ontology that is lavish indeed. It thus conflicts with the spirit of the theory of descriptions, which is (...) developed in the service of ontological frugality. I make use of arguments derived from the Tractatus to show that an ideal language need not contain logical signs. I thus defend the spirit of the theory of descriptions while departing from its letter. (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)

This paper defends a principle I call Equal Treatment, according to which the rationality of a belief is determined in precisely the same way as the rationality of any other state. For example, if wearing a raincoat is rational just in case doing so maximizes expected value, then believing some proposition P is rational just in case doing so maximizes expected value. This contrasts with the popular view that the rationality of belief is determined by evidential support. It also contrasts (...) with the common idea that in the case of belief, there are two different incommensurable senses of rationality, one of which is distinctively epistemic. I present considerations that favor Equal Treatment over these two alternatives, reply to objections, and criticize some arguments for Evidentialism. I also show how Equal Treatment opens the door to a distinctive kind of response to skepticism. (shrink)

This paper responds to Stroud's important The Significance of Philosophical Scepticism. The author defends a view in which statements in a natural language have truth-evaluable content only in concrete contexts. It is argued that just what counts as a concrete possibility that must be defeated before one can say that one knows something is a highly context-sensitive matter, and that Stroud's alternative to this context-sensitive account of the way the verb "know" functions seems to be either a semantics in which (...) knowledge claims (about the "external world") are trivially logically false or no intelligible semantics at all. (shrink)

In this essay, I explain how certain suggestions put forth by Frege. Wittgenstein, and Schlick regarding the interpretation of indexical expressions may be incorporated within a systematic semantic account. I argue that the 'hybrid' approach they propose is preferable to more conventional systems, in particular when it comes to the interpretation of cases of cross-contextual ellipsis. I also explain how the hybrid view entails certain important and independently motivated distinctions among contextually dependent expressions, for instance between 'here' and 'local'.

The combinatory restriction known in linguistics as ‘selection restrictions’ are generally assumed to be a kind of linguistic structures, either syntactic or semantic, or at best cognitive structures. The idea discussed in this paper is that selection restrictions, although relevant for the description of complex meanings of linguistic expressions, do not belong to the structure of either language or cognition in any reasonable sense. Instead, they are criteria for conceptual consistency. They form a layer of shared presuppositions that lie at (...) the grounds of consistent human behaviour and therefore of consistent thought and expression and belong to a natural ontology shared far beyond the boundaries of a given linguistic community.

Alice Crary claims that “the standard view of the bearing of Wittgenstein's philosophy on ethics” is dominated by “inviolability interpretations”, which often underlie conservative readings of Wittgenstein. Crary says that such interpretations are “especially marked in connection with On Certainty”, where Wittgenstein is represented as holding that “our linguistic practices are immune to rational criticism, or inviolable”. Crary's own conception of the bearing of Wittgenstein's philosophy on ethics, which I call the “intrinsically-ethical reading”, derives from the influential New Wittgenstein school (...) of exegesis, and is also espoused by James Edwards, Cora Diamond, and Stephen Mulhall. To my eyes, intrinsically-ethical readings present a peculiar picture of ethics, which I endeavour to expose in Part I of the paper. In Part II I present a reading of On Certainty that Crary would call an “inviolability interpretation”, defend it against New Wittgensteinian critiques, and show that this kind of reading has nothing to do with ethical or political conservatism. I go on to show how Wittgenstein's observations on the manner in which we can neither question nor affirm certain states of affairs that are fundamental to our epistemic practices can be fruitfully extended to ethics. Doing so sheds light on the phenomenon that I call “basic moral certainty”, which constitutes the foundation of our ethical practices, and the scaffolding or framework of moral perception, inquiry, and judgement. The nature and significance of basic moral certainty will be illustrated through consideration of the strangeness of philosophers' attempts at explaining the wrongness of killing. (shrink)

In some sections of On Certainty, Wittgenstein uses the term “persuasion,” pitting it, on the one hand, against “giving reasons”, and comparing it, on the other, to conversion, while, finally, defining it as “giving someone one's own picture of the world.” In this essay, I analyse these sections, in an effort to fit them into the broader context of On Certainty, and to clarify the meaning and the limits of the comparison between persuasion and conversion. My aim is to show (...) that persuasion as Wittgenstein understands it here is quite similar to what we could call “re-education.”. (shrink)

While there is now considerable anxiety about whether the psychological theory presupposed by virtue ethics is empirically sustainable, analogous issues have received little attention in the virtue epistemology literature. This paper argues that virtue epistemology encounters challenges reminiscent of those recently encountered by virtue ethics: just as seemingly trivial variation in context provokes unsettling variation in patterns of moral behavior, trivial variation in context elicits unsettling variation in patterns of cognitive functioning. Insofar as reliability is a condition on epistemic virtue, (...) we have reason to doubt that human beings possess the cognitive materials required for epistemic virtue, and thereby reason to think that virtue epistemology is threatened by skepticism. We conclude that while virtue epistemology has resources for addressing this challenge, exploiting these resources forces tradeoffs between empirical and normative adequacy. (shrink)

Abstract: Some seventy years ago, G. E. Moore invoked his own sensory experience (as of a hand before him in the right circumstances), added some philosophical analysis about externality, and took himself to have offered his "Proof" of the existence of an external world. Current neo-Mooreans either reject completely the standard negative assessment of the Proof or qualify it substantially. For Sosa, the Proof can be persuasive, but only when read literally as offering reasons for the conclusion that there is (...) at least one external object—rather than that the prover is justified in believing, or even knowing, that there is at least one external object. Sosa, then, is a neo-Moorean—though not of the sort we might expect in light of the ongoing debate about the Proof. I argue that Sosa needs to say more about the circularity often thought to vitiate the Proof before we can accept his view. (shrink)

Many epistemologists are interested in offering a positive account of how it is that many of our common sense beliefs enjoy one or another positive epistemological status (e.g., how they are warranted, justified, reasonable, or what have you). A number of philosophers, under the influence of Wittgenstein and/or J. L. Austin, have argued that this enterprise is misconceived. The most effective version of this argument is to be found in Mark Kaplan’s paper “Epistemology on Holiday”. After explaining what this criticism (...) amounts to and why it is important, I then respond to it. My response is based upon, and is intended to display the explanatory power of, a contractarian account of our practice of epistemic appraisal. (shrink)

A skeptic claims that I do not have knowledge of the external world. It has been thought that the skeptic reaches this conclusion because she employs unusually stringent standards for knowledge. But the skeptic does not employ unusually high standards for knowledge. Rather, she employs unusually restrictive standards of evidence. Thus, her claim that we lack knowledge of the external world is supported by considerations that would equally support the claim that we lack evidence for our beliefs about the external (...) world. These considerations do not threaten the truth of our ordinary attributions of evidence, however, for such attributions are context-sensitive in their semantics. It is argued that this solution to the problem of the external world enjoys all of the benefits, and suffers none of the problems, of other solutions to the problem of the external world. (shrink)

In this paper I focus on the notion of worldview as a conceptual scheme and the role of language in shaping our view of reality. In particular, I engage with Wittgenstein’s notion of World-picture in order to suggest an alternative account to the deceptive dogmatic conception of worldview, which is exemplified by C.I. Lewis’s account of cognitive experience. I argue that worldviews constitute the way in which the world is given in a particular socio-linguistic context and they presuppose the mastery (...) of a World-picture, that is, the inherited background of our acting and thinking. First, I will distinguish between two different uses of the term “worldview”. Then I will show the way in which a metaphysical-dogmatic conception of worldview leads to the Myth of the Semantic Given. Finally, I will present Wittgenstein’s notion of World-picture and its connection to the notion of worldview. (shrink)

The transparency argument concludes that we're directly aware of external properties and not directly aware of the properties of experience. Focusing on the presentation used by Michael Tye (2002) I contend that the argument requires experience to have content that it cannot plausibly have. I attribute the failure to a faulty account of the transparency phenomenon and conclude by suggesting an alternative understanding that is independently plausible, is not an error-theory and yet renders the transparency of experience compatible with mental-paint (...) style views. (shrink)

I can be wrong about things I seem to perceive; the conditions might lead me to be mistaken about them. Since I can't rule out the possibility that the conditions are misleading, I can't be sure that I am perceiving this thing in my hand correctly. But suppose that I am able to examine it actively—handling it, looking closer, shining a light on it, and so on. Then, my level of uncertainty goes down; in the limit it is eliminated entirely. (...) Of course, I might be mistaken because I am a brain in a vat, or because some other sceptical scenario obtains. But sceptical scenarios apply not just to this thing in my hand, but to everything all at once. Define "empirical certainty" as the absence of the kind of doubt that spreads to all empirical states of affairs. Sensory exploration, or active examination, can in principle lead to empirical certainty. (shrink)

Epistemic minimalism affirms that mere true belief is sufficient for propositional knowledge. I construct a taxonomy of some specific forms of minimalism and locate within that taxonomy the distinct positions of various advocates of minimalism, including Alvin Goldman, Jaakko Hintikka, Crispin Sartwell, Wolfgang Lenzen, Franz von Kutschera, and others. I weigh generic minimalism against William Lycan’s objection that minimalism is incompatible with plausible principles about relations between knowledge, belief, and confidence. I argue that Lycan’s objection fails for equivocation but that (...) some specific forms of minimalism are better able than others to articulate that defense. (shrink)

ABSTRACTThis paper consists of a story about unorthodox assessment procedures in theology, and a discussion of their implications. Among the issues raised are the possibility of testing values, the relationship of test validity to test reliability and ethical questions involved in assessment.

This paper seeks to defend, develop, and revise Edward Craig's “genealogy of knowledge”. The paper first develops the suggestion that Craig's project is naturally thought of as an important instance of “social cognitive ecology”. It then introduces the genealogy of knowledge and some of its main problems and weaknesses, suggesting that these are best taken as challenges for further work rather than as refutations. The central sections of the paper conduct a critical dialogue between Craig's theory and Wittgenstein's claim–familiar from (...) On Certainty–that common-sense certainties cannot be known. It turns out that Craig's distinction between different stages in the development of our concept of knowledge can illuminate and make plausible Wittgenstein's claim. But it can do so only if Craig's traditional commitment to a central “core” in our concept of knowledge is replaced with the idea of knowledge as a family-resemblance concept. (shrink)

Epistemic and moral certainities like ' This is a hand' or 'Killing people is evil' will be interpreted as constitutive rules of language games, such that they are unjustifiable, undeniable and serving as obliging standards of truth, goodness and rationality for members of a community engaging in the respective practices.

The debate surrounding eliminative materialism, and the role of empiricism more broadly, has been one of the more prominent philosophical debates of the last half-century. But too often what is at stake in this debate has been left implicit. This essay surveys the rhetoric of two participants in this debate, Paul Churchland and Thomas Nagel, on the question of whether or not scientific explanations will do away with the need for nonscientific descriptions. Both philosophers talk about this possibility in language (...) reminiscent of revolutionary politics. These authors do not see eliminative materialism merely as an idea to be evaluated, but a revolution to be welcomed or quashed. After surveying their rhetoric, the paper turns to the work of four philosophers—G.E.M. Anscombe, Peter Winch, Paul Holmer, and G.H. von Wright—to suggest that there is within Wittgensteinian tradition a ‘nonrevolutionary’ approach to the question of eliminative materialism. (shrink)

It is argued in this article that the concept of practice is one of the key concepts in Wittgenstein's later philosophy. It partly replaces his earlier talk about the inexpressible. ?The practice has to speak for itself, as Wittgenstein succinctly puts it. The concept of practice not only points to the ways in which the unity of our concepts are underpinned, as Gordon Baker has it, it also comprises the skills involved in handling the conceptualized phenomena, our prereflective familiarity with (...) them, expressed in the sureness in our behaviour towards them, and the judgmental power exercised in applying or withholding a given concept on a particular occasion. These factors are all relevant to the establishment of knowledge, but they cannot themselves be fully and straightforwardly articulated by verbal means. Nevertheless, they represent what we go by when we apply concepts and other types of rules. To follow a rule is what Wittgenstein calls a practice. The sketched analysis of this concept makes us understand better how it is possible to apply a rule without the support of another rule. It also makes us realize in what sense one is justified in talking about tacit knowledge in connection with the application of concepts and rule?following in general. Quite a lot hangs on seeing the world aright at this point. (shrink)

The power of Wittgenstein's N operator described in the Tractatus is that every proposition which can be expressed in the Russellian variant of the predicate calculus familiar to him has an equivalent proposition in an extended variant of his N operator notation. This remains true if the bound variables are understood in the usual inclusive sense or in Wittgenstein's restrictive exclusive sense. The problematic limit of Wittgenstein's N operator comes from his claim that symbols alone reveal the logical status of (...) propositions. This would require knowledge of the size of the Tractarian domain of unchangeable, simple objects, and this, Wittgenstein maintained, cannot be known. (shrink)
