An epistemological how-possible question asks how knowledge, or knowledge of some specific kind, is possible. The main contention of Duncan Pritchard‟s stimulating comments is that what I call „explanatory minimalism‟ appears to offer us just what we are seeking when we ask such a question. This looks like a problem for me given that I defend a version of explanatory anti-minimalism. Pritchard outlines a version of minimalism inspired by the writings of John McDowell and does not find it obvious that (...) this position is lacking in any relevant respect. Nor do I. My minimalism is moderate rather than extreme but Pritchard‟s objections to anti-minimalism are objections to extreme anti-minimalism. Indeed, his comments do not seem to me to have any direct bearing on what I take to be the fundamental disagreement between minimalism and anti-minimalism. (shrink)

The standard taxonomy of theories of epistemic justification generates four positions from the Foundationalism v. Coherentism and Internalism v. Externalism disputes. I develop a new taxonomy driven by two other distinctions: Fundamentalism v. Non-Fundamentalism and Actual-Result v. Proper-Aim conceptions of epistemic justification. Actual-Result theorists hold that a belief is justified only if, as an actual matter of fact, it is held or formed in a way that makes it more likely than not to be true. Proper-Aim theorists hold that a (...) belief is justified only if it is held or formed in a way that it proper or correct insofar as truth is the aim or norm. Fundamentalists hold that which particular ways of holding or forming beliefs that confer justification is knowable a priori; epistemic principles are a priori necessary truths. Non- Fundamentalists disagree; epistemic principles are empirical contingent truths. The new taxonomy generates four positions: Cartesianism, Reliabilism, Intuitionism, and Pragmatism. The first two are Actual-Result; the second two are Proper-Aim. The first and third are Fundamentalist, the second and fourth are Non-Fundamentalist. The new taxonomy illuminates much of the current debate in the theory of epistemic justification. (shrink)

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? (...) Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

This paper argues that formal models of coherence are useful for constructing a legal epistemology. Two main formal approaches to coherence are examined: coherence-based models of belief revision and the theory of coherence as constraint satisfaction. It is shown that these approaches shed light on central aspects of a coherentist legal epistemology, such as the concept of coherence, the dynamics of coherentist justification in law, and the mechanisms whereby coherence may be built in the course of legal decision-making.

How all philosophical explanations of human consciousness and the fundamental structure of the cosmos are bizarre—and why that’s a good thing Do we live inside a simulated reality or a pocket universe embedded in a larger structure about which we know virtually nothing? Is consciousness a purely physical matter, or might it require something extra, something nonphysical? According to the philosopher Eric Schwitzgebel, it’s hard to say. In The Weirdness of the World, Schwitzgebel argues that the answers to these fundamental (...) questions lie beyond our powers of comprehension. We can be certain only that the truth—whatever it is—is weird. Philosophy, he proposes, can aim to open—to reveal possibilities we had not previously appreciated—or to close, to narrow down to the one correct theory of the phenomenon in question. Schwitzgebel argues for a philosophy that opens. According to Schwitzgebel’s “Universal Bizarreness” thesis, every possible theory of the relation of mind and cosmos defies common sense. According to his complementary “Universal Dubiety” thesis, no general theory of the relationship between mind and cosmos compels rational belief. Might the United States be a conscious organism—a conscious group mind with approximately the intelligence of a rabbit? Might virtually every action we perform cause virtually every possible type of future event, echoing down through the infinite future of an infinite universe? What, if anything, is it like to be a garden snail? Schwitzgebel makes a persuasive case for the thrill of considering the most bizarre philosophical possibilities. (shrink)

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

Contemporary epistemology has explored the notion of a hinge commitment as set out in Wittgenstein’s final notebooks, published as On Certainty. These are usually understood as essentially groundless certainties that provide the necessary framework within which rational evaluations can take place. John Greco has recently offered a striking account of hinge commitments as a distinctive kind of knowledge that he calls ‘common knowledge’. According to Greco, this is knowledge that members of the community get to have without incurring any epistemic (...) burden, and as such is fundamentally different from other kinds of knowledge. I offer a critique of Greco’s proposal. While I agree that there is a variety of knowledge that counts as common knowledge, I contend that it is not to be understood as knowledge that one gets for free as Greco suggests. Moreover, I argue that our hinge commitments do not count as common knowledge—either in Greco’s sense of the term or in the alternative manner that I set out—because properly understood they are not in the market for knowledge at all. In defence of this claim, I suggest that Greco’s conception of a hinge commitment is both missing some crucial elements and also too broad in its extension, in that it encompasses both instances of common knowledge and hinge commitments proper.

It has been argued that an advantage of the safety account over the sensitivity account is that the safety account preserves epistemic closure, while the sensitivity account implies epistemic closure failure. However, the argument fails to take the method-relativity of the modal conditions on knowledge, viz., sensitivity and safety, into account. In this paper, I argue that the sensitivity account and the safety account are on a par with respect to epistemic closure once the method-relativity of the modal conditions is (...) taken into account. Therefore, epistemic closure is no longer an arbiter in the debate. (shrink)

In this talk I present the main results from Anta (2021), namely, that the theoretical division between Boltzmannian and Gibbsian statistical mechanics should be understood as a separation in the epistemic capabilities of this physical discipline. In particular, while from the Boltzmannian framework one can generate powerful explanations of thermal processes by appealing to their microdynamics, from the Gibbsian framework one can predict observable values in a computationally effective way. Finally, I argue that this statistical mechanical schism contradicts the Hempelian (...) (1958) thesis that the predictive power of a scientific theory is directly proportional to its explanatory potential, and vice versa. (shrink)

This paper examines the relationship between the KK principle and the epistemological theses of externalism and internalism. In particular we examine arguments from Okasha (Analysis 73(1):80–86, 2013) and Greco (J Philos 111(4):169–197, 2014) which deny that we can derive the denial of the KK principle from externalism.

Skeptical invariantism isn’t a popular view about the semantics of knowledge attributions. But what, exactly, is wrong with it? The basic problem is that it seems to run foul of the fact that we know quite a lot of things. I agree that it is a key desideratum for an account of knowledge that it accommodate the fact that we know a lot of things. But what sorts of things should a plausible theory of knowledge say that we know? In (...) this paper I sketch an answer to this question and then apply it to skeptical invariantism. I start by distinguishing between a “radical” skeptical invariantist position (on which the standards for knowing are so high that we rarely if ever satisfy them) and a more “moderate” skeptical invariantist position (on which the standards are very hard, but not impossible, to satisfy). I then argue that, while radical forms of skeptical invariantism are clearly not going to do a good job of satisfying the key desideratum, more moderate forms can do quite well with respect to it. In particular, I argue the version of moderate skeptical invariantism defended by Davide Fassio can plausibly satisfy it. (shrink)

Nuno Venturinha holds that the contextualist epistemology adumbrated in Wittgenstein’s On Certainty--the most powerful response to philosophical skepticism yet developed-- falls short of providing a complete answer to Cartesian radical skepticism about knowledge of the external world. I argue that Venturinha underestimates the range and complexity of Wittgenstein’s epistemological. He does so because he reads Wittgenstein along the lines of so-called ‘hinge epistemology’. Hinge epistemology indeed fails as a diagnosis of skepticism. But it also fails as a reading of Wittgenstein. (...) A more adequate understanding of Wittgenstein suggests that Venturinha’s pessimistic conclusion can be avoided. (shrink)

‘Relativism’ is often treated as a dirty word in philosophy. Showing that a view entails relativism is almost always considered tantamount to showing that it is nonsensical. However, relativistic theories are not entirely unappealing – they have features which might be tempting if they weren’t thought to be outweighed by problematic consequences. In this paper I argue that it’s possible to secure the intuitively appealing features of at least one kind of relativism – epistemic relativism – without having to accept (...) any problematic consequences. I do this by defending what I call 'stratified relativism'. (shrink)

Carter and Pritchard (2016) and Pritchard (2010, 2012, 2016) have tried to reconcile the intuition that perceptual knowledge requires only limited discriminatory abilities with the closure principle. To this end, they have introduced two theoretical innovations: a contrast between two ways of introducing error-possibilities and a distinction between discriminating and favoring evidence. I argue that their solution faces the “sufficiency problem”: it is unclear whether the evidence that is normally available to adult humans is sufficient to retain knowledge of the (...) entailing proposition and come to know the entailed proposition. I submit that, on either infallibilist or fallibilist views of evidence, Carter and Pritchard have set the bar for deductive knowledge too low. At the end, I offer an alternative solution. I suggest that the knowledge-retention condition of the closure principle is not satisfied in zebra-like scenarios. (shrink)

Two of the most orthodox ideas in epistemology are fallibilism and purism. According to the fallibilist, one can know that a particular claim is true even though one’s justification for that claim is less than fully conclusive. According to the purist, knowledge does not depend on practical factors. Fallibilism and purism are widely assumed to be compatible; in fact, the combination of these views has been called the ‘ho-hum,’ obvious, traditional view of knowledge. But I will argue that fallibilism and (...) purism are incompatible. The best explanation for fallibilism requires one to reject purism, while maintaining purism should lead one to reject fallibilism. It follows that the orthodox view of knowledge is deeply mistaken.

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

It is argued that standard accounts of the epistemology of religious commitmentfail to be properly sensitive to certain important features of the nature of religious conviction. Once one takes these features of religious conviction seriously, then it becomes clear that we are not to conceive of the epistemology of religious conviction along completely rational lines.But the moral to extract from this is not fideism, or even a more moderate proposal that casts the epistemic standing of basic religious beliefs along nonrational (...) lines. Rather, one needs to recognise that in an important sense religious convictions are not beliefs at all, but that this is compatible with the idea that many other religious commitments are beliefs. This picture of the nature of religious commitment is shown to fit snugly with the Wittgensteinian account of hinge commitments, such that all rational belief essentially presupposes certain basic arational hinge commitments, along lines originally suggested by John Henry Newman. We are thus able to marshal a parity-style argument in defence of religious commitment. Although religious belief presupposes basic arational religious convictions, it is not on this score epistemically amiss since all belief presupposes basic arational convictions, or hinge commitments. The resulting view of the epistemology of religious commitment is a position I call quasi-fideism. (shrink)

This thesis investigates Hume’s philosophy of external existence in relation to, and within the context of, his philosophy of scepticism. In his two main works on metaphysics – A Treatise of Human Nature (1739–40) and the first Enquiry (first ed. 1748) – Hume encounters a predicament pertaining to the unreflective, ‘vulgar’ attribution of external existence to mental perceptions and the ‘philosophical’ distinction between perceptions and objects. I argue that we should understand this predicament as follows: the vulgar opinion is our (...) natural and default belief for Hume, but causal reasoning reveals it to be false, and the philosophical alternative is a confabulation that we cannot permanently believe and is devoid of justification. Hume uses the fact that we cannot have a satisfactory account of belief in external existence as a sceptical consideration to motivate his wider philosophical scepticism. Hume’s response to his predicament about external existence is found in the context of his confrontation with other sceptical worries (Treatise 1.4.7 and Enquiry 12), in which Hume also reflects generally on the nature and implications of scepticism. I argue that we should characterise Hume’s position as residually sceptical. This means that, while Hume accepts the unanswerability of some sceptical problems, he denies that it is possible to eradicate all belief as a result (and denies that it is practically useful to even try) and instead uses sceptical problems as a motivation to adopt a moderately sceptical position. While we inevitably return to entertaining the vulgar belief, there is no solution to the sceptical predicament; Hume does not endorse the vulgar belief, or the philosophical system, or indeed any alternative system of the external world that might extinguish the predicament. Sceptical doubt, for Hume, does not derail intellectual pursuits, but rather modifies our attitudes in those very pursuits. (shrink)

Duncan Pritchard recently proposed a Wittgensteinian solution to closure-based skepticism. According to Wittgenstein, all epistemic systems assume certain truths. The notions that we are not disembodied brains, that the Earth has existed for a long time and that one’s name is such-and-such all function as “hinge commitments.” Pritchard views a hinge commitment as a positive propositional attitude that is not a belief. Because closure principles concern only knowledge-apt beliefs, they do not apply to hinge commitments. Thus, from the fact that (...) a subject knows that he is sitting in a room, and the fact that the subject’s sitting in a room entails his bodily existence, it does not follow that the subject also knows that he is not an envatted brain. This paper rejects Pritchard’s non-belief reading of hinge commitments. I start by showing that the non-belief reading fails to solve the skeptical paradox because the reasons that Pritchard uses to support the non-belief reading do not exempt hinge propositions from closure principles. I then proceed to argue that the non-belief reading is false as it claims that hinge commitments, unlike ordinary beliefs, are rationally unresponsive—with the help of a scenario in which a subject’s experience is internally chaotic, we can safely conclude that the hinge commitment that one is not systematically mistaken about the world is equally responsive to one’s evidential situations.

For several decades, renewed interest in the connection between perception and knowledge has sustained a robust debate over external world skepticism. Recently, however, a growing consensus claims the skeptical challenge has been substantially met, and that realism in some robust form has emerged a clear victor. I invite us to rethink this consensus in a two-part response. The first forges a temporary alliance with skepticism against prominent forms of contemporary realism. That these fail to rebuff ews bolsters Barry Stroud’s call (...) for a new paradigm of objectivity. In the second part I sketch such a paradigm based upon a transactional interpretation of John Dewey’s pragmatism, and indicate its resilience to skeptical attacks. (shrink)

Epistemological contextualism ‐ the claim that the truth‐value of knowledge‐attributions can vary with the context of the attributor ‐ has recently faced a whole series of objections. The most serious one, however, has not been discussed much so far: the factivity objection. In this paper, I explain what the objection is and present three different versions of the objection. I then show that there is a good way out for the contextualist. However, in order to solve the problem the contextualist (...) has to accept a relationalist version of contextualism. (shrink)

Radical skepticism relies on the hypothesis that one could be completely cut off from the external world. In this paper, I argue that this hypothesis can be rationally motivated by means of a conceivability argument. Subsequently, I submit that this conceivability argument does not furnish a good reason to believe that one could be completely cut off from the external world. To this end, I show that we cannot adequately conceive scenarios that verify the radical skeptical hypothesis. Attempts to do (...) so fall prey to one or another of three pitfalls: they end up incomplete, reveal a deep contradiction or recreate a non-skeptical hypothesis. I use these results to improve upon Pritchard’s recent attempt at undercutting radical skepticism. (shrink)

This paper responds to the generous comments by Alexander Klein and Cheryl Misak on my “American Pragmatism and the Vienna Circle: The Early Years”. First, besides offering some clarification of my original thesis, I argue that Jerusalem was not liable to the anti-Spencerian criticisms by James that Klein adduces in the course of defending James against the charge of psychologism. Then I investigate the impact of Wittgenstein’s Ramsey-derived pragmatism, importantly foregrounded by Misak, on the Vienna Circle and argue that it (...) was mainly limited to Schlick but not recognized as pragmatist, also leaving unaffected the impact of James’s pragmatism on Frank, Hahn and Neurath specified in my original paper. That said, Klein’s and Misak’s comments add significantly to our understanding of long-neglected transatlantic philosophical connections in the early twentieth century. (shrink)

_ Source: _Volume 6, Issue 2-3, pp 97 - 119 In this paper, I briefly summarize the nature of Wittgenstein’s ‘hinge certainties,’ showing how they radically differ from traditional basic beliefs in their being nonepistemic, grammatical, nonpropositional, and enacted. I claim that it is these very features that enable hinge certainties to put a logical stop to justification, and thereby solve the regress problem of basic beliefs. This is a ground-breaking achievement—worthy of calling _On Certainty_ Wittgenstein’s ‘third masterpiece.’ As I (...) go along, I question some differing interpretations and respond to some objections from fellow-readers of _On Certainty_: Duncan Pritchard, Michael Williams, and Crispin Wright.

_ Source: _Volume 5, Issue 1, pp 13 - 28 Linking the idea of knowledge with the idea of a certain form of life is uncontestedly one of the lessons the later Wittgenstein wanted to teach us. However, what Wittgenstein exactly meant by this is highly contested in the Wittgenstein literature. In this paper, I distinguish two ways of appealing to the idea of a form of life in order to understand knowledge. According to the first way, the appeal to (...) the idea of a form of life is supposed to “solve” the skeptical problem. On that account the appeal to a form of life is conceived of as an appeal to something that is more fundamental than knowledge and thereby explains how knowledge is possible. According to the second way, the appeal to the idea of a form of life is taken to be a consequence of an insight that makes it impossible for the skeptical problem to even get formulated: it is the insight that the fundamental meaning of the concept of knowledge is to describe a kind of capacity, more precisely, a capacity for knowledge. I take this to be Wittgenstein’s deepest lesson for epistemology which is still to be acknowledged. According to this interpretation, the thought that knowledge is linked with a certain form of life no longer expresses the idea that knowledge rests upon something that is more fundamental than knowledge. It rather expresses the idea that knowledge rests upon a form of life that cannot exist without knowledge. (shrink)

A very natural view about perceptual knowledge is articulated, one on which perceptual knowledge is closely related to perceptual discrimination, and which fits well with a relevant alternatives account of knowledge. It is shown that this kind of proposal faces a problem, and various options for resolving this difficulty are explored. In light of this discussion, a two-tiered relevant alternatives account of perceptual knowledge is offered which avoids the closure problem. It is further shown how this proposal can: accommodate our (...) intuitions about perceptual knowledge and perceptual discrimination in terms of the notion of primary relevance, give an account of how alternatives can be rationally excluded without appeal to perceptual discrimination in terms of the notion of secondary relevance, and deal with the problem posed by inverted Gettier cases, and hence explain what it means to rationally exclude alternatives which are of secondary relevance.

According to Duncan Pritchard, there are two kinds of radical sceptical problem; the closure-based problem, and the underdetermination-based problem. He argues that distinguishing these two problems leads to a set of desiderata for an anti-sceptical response, and that the way to meet all of these desiderata is by supplementing a form of Wittgensteinian contextualism with disjunctivist views about factivity. I agree that an adequate response should meet most of the initial desiderata Pritchard puts forward, and that some version of Wittgensteinian (...) contextualism shows the most promise as a starting point for this, but I argue, contra Pritchard, that the addition of disjunctivism is unnecessary and potentially counter-productive. If we draw on lessons from Michael Williams's inferential contextualism then it is both possible, and preferable, to meet the most important of Pritchard's desiderata, undercutting both closure-based and underdetermination-based sceptical problems in a unified way, without the need to resort to disjunctivism.

I present the arguments Hegel puts forward in favor of this rather challenging account of skepticism. In Section 2, I discuss the celebrated conception of “self-fulfilling skepticism” of the Phenomenology of Spirit that is supposed to overcome untrue types of cognition in order to promote “absolute knowing.” In Section 3, I debate Hegel’s more advanced view according to which genuine skepticism must be construed as dialectic.

The regress of reasons threatens an epistemic agent’s right to claim that any beliefs are justified. In response, Peter Klein’s infinitism argues that an infinite series of supporting reasons of the right type not only is not vicious but can make for epistemic justification. In order to resist the sceptic, infinitism needs to provide reason to think that there is at least one justified belief in the world. Under an infinitist conception this involves showing that at least one belief is (...) supported by an infinite series of supporting reasons. This paper argues that showing this makes problems for the infinitist. The finite minds problem that prevents completion of an infinite series is well documented. This paper examines alternative attempts to provide evidence of infinity that the infinitist might take, whether by using a notion of justification without infinite reasons or by altering the notion of evidence. It concludes that both of these fail and consequently infinitism is unable to offer a solution to Agrippa’s trilemma. (shrink)

On the standard view, pessimism is a philosophically intractable topic. Against the standard view, I hold that pessimism is a stance, or compound of attitudes, commitments and intentions. This stance is marked by certain beliefs—first and foremost, that the bad prevails over the good—which are subject to an important qualifying condition: they are always about outcomes and states of affairs in which one is personally invested. This serves to distinguish pessimism from other views with which it is routinely conflated— including (...) skepticism and nihilism—and to allow for the extent to which pessimism necessarily involves more than the intellectual endorsement of a doctrine.

In his final notebooks, published as On Certainty , Wittgenstein offers a distinctive conception of the nature of reasons. Central to this conception is the idea that at the heart of our rational practices are essentially arational commitments. This proposal marks a powerful challenge to the standard picture of the structure of reasons. In particular, it has been thought that this account might offer us a resolution of the traditional scepticism/anti-scepticism debate. It is argued, however, that some standard ways of (...) filling out the details of this proposal ultimately lead to an epistemology which is highly problematic. The goal here is to present a more compelling version of Wittgenstein’s account of the structure of reasons which can evade these difficulties. (shrink)

Laws of nature take center stage in philosophy of science. Laws are usually believed to stand in a tight conceptual relation to many important key concepts such as causation, explanation, confirmation, determinism, counterfactuals etc. Traditionally, philosophers of science have focused on physical laws, which were taken to be at least true, universal statements that support counterfactual claims. But, although this claim about laws might be true with respect to physics, laws in the special sciences (such as biology, psychology, economics etc.) (...) appear to have—maybe not surprisingly—different features than the laws of physics. Special science laws—for instance, the economic law “Under the condition of perfect competition, an increase of demand of a commodity leads to an increase of price, given that the quantity of the supplied commodity remains constant” and, in biology, Mendel's Laws—are usually taken to “have exceptions”, to be “non-universal” or “to be ceteris paribus laws”. How and whether the laws of physics and the laws of the special sciences differ is one of the crucial questions motivating the debate on ceteris paribus laws. Another major, controversial question concerns the determination of the precise meaning of “ceteris paribus”. Philosophers have attempted to explicate the meaning of ceteris paribus clauses in different ways. The question of meaning is connected to the problem of empirical content, i.e., the question whether ceteris paribus laws have non-trivial and empirically testable content. Since many philosophers have argued that ceteris paribus laws lack empirically testable content, this problem constitutes a major challenge to a theory of ceteris paribus laws. (shrink)

A commonly expressed worry in the contemporary literature on the problem of epistemological scepticism is that there is something deeply intellectually unsatisfying about the dominant anti-sceptical theories. In this paper I outline the main approaches to scepticism and argue that they each fail to capture what is essential to the sceptical challenge because they fail to fully understand the role that the problem of epistemic luck plays in that challenge. I further argue that scepticism is best thought of not as (...) a quandary directed at our possession of knowledge simpliciter, but rather as concerned with a specific kind of knowledge that is epistemically desirable. On this view, the source of scepticism lies in a peculiarly epistemic form of angst. It is always by favour of Nature that one knows something. [Wittgenstein 1969: §505]. (shrink)

Guided by an account of the norms governing justificatory conversations, I propose that person-level epistemic justification is a matter of possessing a certain ability: the ability to provide objectively good reasons for one's belief by drawing upon considerations which one responsibly and correctly takes there to be no reason to doubt. On this view, justification requires responsible belief and is also objectively truth-conducive. The foundationalist doctrine of immediately justified beliefs is rejected, but so too is the thought that coherence in (...) one's total belief system is sufficient, or indeed necessary, for justification. The problem of the regress is solved by exploiting the 'localist' idea that in order to possess the ability to justify any given belief, one only needs to be in a position to draw upon appropriate justified background beliefs to provide good reasons for holding the belief; one needn't be able to defend the relevant background beliefs, and so on, all at one sitting.

But it’s not the mere fact that the RA theorist needs an account of ‘ruling out’ and ‘relevance’ that has tended to lead people to regard the RA approach with suspicion. In itself, this simply means that the RA theorist has some further work to do; and what theorist doesn’t? No; the principal source of scepticism regarding the ability of the RA theorist to come up with a complete and satisfactory account of knowing stems, rather, from an unhappiness with the (...) specific elaborations of the core RA claim that various theorists have offered; for these elaborations have typically involved some rather controversial claims and/or assumptions, and it is against these claims/assumptions that the bulk of the criticism of the whole RA approach has been directed.

I introduce the key ideas of foundationalist, coherentist and pragmatist theories of knowledge. I then use these ideas as background for presenting the work on knowledge and perception in this part, work by Grace Andrus de Laguna and Marie Collins Swabey. We will see that these authors critique the idea of sense data that was central to the foundationalist theories of knowledge of Bertrand Russel and other early analytic thinkers, though de Laguna’s critique leads to perspectivism about perception and knowledge (...) while Swabey rejects perspectivism. So too, we will see that de Laguna and Swabey develop epistemologies with strong coherentist elements, much as did their idealist teacher James Edwin Creighton. De Laguna’s, developed jointly with her husband, Theodore de Laguna, is a sophisticated form of naturalism that is built on a critique of pragmatist naturalism and is similar to the one made famous later by Willard V. Quine. Swabey rejects all forms of naturalism, arguing that knowledge requires an a priori foundation in reason. (shrink)

I argue in this paper that, like the Pyrrhonism of Sextus Empiricus, Wittgenstein’s response to negative–dogmatic skepticism in On Certainty turns on the attempt to free us from the demands of traditional philosophy and is therefore not a philosophical position, strictly speaking. Rather, it is a therapeutic metaphilosophy designed to bring into view (i.e., to illumine) the relationship between our everyday epistemic practices and those of philosophy such that we simultaneously come to recognize (a) what I call the pragmatic–transcendental self–standingness (...) of the everyday and (b) its philosophical–rational groundlessness. The Pyrrhonian illumination of the everyday is therapeutic in that it aims to purify our metadoxastic attitudes of dogmatism. (shrink)

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

Deep disagreements concern our most basic and fundamental commitments. Such disagreements seem to be problematic because they appear to manifest epistemic incommensurability in our epistemic systems, and thereby lead to epistemic relativism. This problem is confronted via consideration of a Wittgensteinian hinge epistemology. On the face of it, this proposal exacerbates the problem of deep disagreements by granting that our most fundamental commitments are essentially arationally held. It is argued, however, that a hinge epistemology, properly understood, does not licence epistemic (...) incommensurability or epistemic relativism at all. On the contrary, such an epistemology in fact shows us how to rationally respond to deep disagreements. It is claimed that if we can resist these consequences even from the perspective of a hinge epistemology, then we should be very suspicious of the idea that deep disagreements in general are as epistemologically problematic as has been widely supposed.

In On Certainty, §166, Wittgenstein mentions the difficulty of realizing the “groundlessness of our believing.” In the course of reviewing what makes this realization so difficult, I examine a certain way of understanding one of Wittgenstein's techniques for getting us to realize it, his use of the “hinge” metaphor. It implies that hinge-propositions possess that status inherently; for some commentators, this is because of their connection to instinctive and habitual behaviours. I offer an alternative interpretation of the remarks that have (...) been used to support this understanding that better explains their role in Wittgenstein's response to scepticism and other epistemological problems.

Although certainty is a fundamental notion in epistemology, it is less studied in contemporary analytic epistemology than other important notions such as knowledge or justification. This paper focuses on Wittgensteinian certainty, according to which the very basic dimension of our epistemic practices, the elements of our world-pictures, are objectively certain, in that we cannot legitimately doubt them. The aim of the paper is to offer the best philosophical way to clarify Wittgensteinian certainty, in a way that is consonant with Wittgenstein's (...) fundamental insights. The paper critiques two alternative proposals for clarifying Wittgensteinian certainty that are philosophically unsatisfying: the rule view and the proposition view. Finally, it instead shows how viewing world-pictures as pictures, in the sense of unclear conceptions, is a more philosophically fruitful approach to understanding world-pictures. (shrink)

_ Source: _Volume 7, Issue 3, pp 147 - 172 The Indian Buddhist philosopher Vasubandhu has seldom been considered in conjunction with the problem of external-world skepticism despite the fact that his text, _Twenty Verses_, presents arguments from ignorance based on dreams.

On either interpretation, Vasubandhu gives an invitation to the problem of external-world skepticism, although his final conclusion is closer to skepticism (...) on the epistemological phenomenalist interpretation. The article ends with reflections on what light Vasubandhu might shed on the issue of whether skepticism is a natural problem in epistemology as well as why, despite Vasubandhu, the skeptical problem was not a central issue in the later Indian tradition.

The skeptical puzzle consists of three independently plausible yet jointly inconsistent claims: (A) S knows a certain ordinary proposition op; (B) S does not know the denial of a certain skeptical hypothesis sh; and (C) S knows that op only if S knows that not- sh. The variantist solution (to the skeptical puzzle) claims that (A) and not-(B) are true in the ordinary context, but false in the skeptical one. Epistemic contextualism has offered a standards-variantist solution, which is the most (...) prominent variantist solution on the market. In this paper, I argue that the standards-variantist solution in general (and the contextualist solution in particular) is epistemically uninteresting. Proponents of the variantist solution should opt for the position-variantist solution instead. I will discuss some important implications of my findings. (shrink)

Stroud has argued for many years that skepticism is conditionally correct. We cannot, he claims, both undergo a Cartesian-style examination of the extent of our knowledge as well as avoid skepticism. One reason Stroud's position appears quite plausible is the so-called "totality condition" imposed for this kind of examination: as inquiring philosophers we are called upon to assess all of our knowledge, all at once. However, in this paper I argue that Stroud's apparent understanding of the totality condition is mistaken. (...) Evidently, Stroud thinks that honoring the totality condition amounts to imposing the strong requirement that we initially assume that we don't know anything about external reality. However, there is a weaker requirement available: that we initially not assume that we know anything about external reality. I argue i) that the weaker conception of the totality condition is most suitable for the kind of philosophical examination that Stroud seems to have in mind; and ii) that according to this same conception skepticism is not conditionally correct.
