Epistemological disjunctivism (ED) has been thought to solve the conditionality problem for epistemic externalism. This problem arises from externalists’ characterization of our epistemic standings as conditional on the obtaining of worldly facts which we lack any reflective access to. ED is meant to avoid the conditionality problem by explicating subjects’ perceptual knowledge in paradigmatic cases of perceptual knowledge via their possession of perceptual reasons that are both factive and reflectively accessible. I argue that ED’s account of reflectively accessible factive perceptual (...) reasons is also prey to the conditionality problem. After that, I submit that Stroud’s influential formulation of the conditionality problem relies on a methodological requirement that is potentially dissociable from ED. So, it is possible to put ED in the service of a more modest anti-skeptical strategy. I close by suggesting that this modest anti-skeptical strategy successfully undercuts the underdetermination-based skeptical paradox. Nevertheless, it does not have substantial advantages over some forms of epistemic externalism. (shrink)

According to epistemological disjunctivism (ED), in paradigmatic cases of perceptual knowledge, a subject, S, has perceptual knowledge that p in virtue of being in possession of reasons for her belief that p which are both factive and reflectively accessible to S. It has been argued that ED is better placed than both knowledge internalism and knowledge externalism to undercut underdetermination-based skepticism. I identify several principles that must be true if ED is to be uniquely placed to attain this goal. After (...) that, I use those principles to formulate a diachronic skeptical argument. This argument yields the counterintuitive conclusion that understanding a global skeptical hypothesis is all it takes for a rational subject to lose all her perceptual knowledge of the world. Next, I show that a popular Austinian move must reject one or another of the principles that underlie ED. I close by delineating a novel strategy that can block the diachronic skeptical argument while preserving all the principles. The key idea is that perceptual knowledge is grounded in primitive, perceptual and recognitional abilities. This view sheds new light on some puzzling features of global skepticism that have been noted by Descartes and Hume, among others. (shrink)

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.

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.

Intellectual humility plays a crucial role among intellectual virtues. It has attracted considerable attention from virtue epistemologists, who have offered a fair number of treatments. In this essay, I argue that, regardless of the difference among these treatments, they are beset by two problems: they fall into a circular argument; they fall into a self-referential contradiction. I then argue that a recent proposal by D. Pritchard allows us to avoid, but not. However, by combining this proposal with another reflection advanced (...) by the same author while he discusses the Wittgensteinian notion of hinge commitments, it is possible to avoid. The thesis that emerges is that only a partial application of intellectual humility solves. Finally, I reinforce this thesis by rejecting an alternative solution to. (shrink)

In this essay, we put forth a novel solution to Plantinga’s Evolutionary Argument Against Naturalism, utilizing recent work done by Duncan Pritchard on radical skepticism. Key to the success of Plantinga’s argument is the doubting of the reliability of one’s cognitive faculties. We argue (viz. Pritchard and Wittgenstein) that the reliability of one’s cognitive faculties constitutes a hinge commitment, thus is exempt from rational evaluation. In turn, the naturalist who endorses hinge epistemology can deny the key premise in Plantinga’s argument (...) and avoid the dilemma posed on belief in the conjunction of naturalism and evolution.

In this paper I claim that perceptual discriminatory skills rely on a suitable type of environment as an enabling condition for their exercise. This is because of the constitutive connection between environment and perceptual discriminatory skills, inasmuch as such connection is construed from an ecological approach. The exercise of a discriminatory skill yields knowledge of affordances of objects, properties, or events in the surrounding environment. This is practical knowledge in the first-person perspective. An organism learns to perceive an object by (...) becoming sensitized to its affordances. I call this position ecological disjunctivism. A corollary of this position is that a case of perception and its corresponding case of hallucination—which is similar to the former only in some respects—are different in nature. I show then how the distinguishability problem is addressed by ecological disjunctivism. (shrink)

Half a century later, a Dretskean stance on epistemic closure remains a minority view. Why? Mainly because critics have successfully poked holes in the epistemologies on which closure fails. However, none of the familiar pro-closure moves works against the counterexamples on display here. It is argued that these counterexamples pose the following dilemma: either accept that epistemic closure principles are false, and steal the thunder from those who attack classical logic on the basis of similarly problematic cases—specifically, relevance logicians and (...) like-minded philosophers—or stick with closure and surrender to relevantist claims of failure in truth-preservation aimed at classical rules of inference. Classicist closure advocates find the promise of a way out of the dilemma in the works of Roy Sorensen and John Hawthorne. The paper argues against their pro-closure move and renews Robert Audi’s call for a theory of closure-failure. (shrink)

Philosophers disagree. A lot. Pervasive disagreement is part of the territory; consensus is hard to find. Some think this should lead us to embrace philosophical skepticism: skepticism about the extent to which we can know, or justifiably believe, the philosophical views we defend and advance. Most philosophers in the literature fall into one camp or the other: philosophical skepticism or philosophical anti-skepticism. Drawing on the insights of hinge epistemology, this paper proposes another way forward, an intermediate position that appeals both (...) to skeptical and anti-skeptical intuitions concerning the possibility and scope of philosophical knowledge. The main advantage of our account is that it’s able to recover some philosophical knowledge while also being compatible with philosophical skepticism. (shrink)

Despite its intrinsic plausibility, the sensitivity principle has remained deeply unpopular on the grounds that it violates an even more plausible closure principle. Here we show that sensitivity does not, in general, violate closure. Sensitivity only violates closure when combined with further auxiliary premises—regarding which of an agent’s commitments constitute that agent’s beliefs—which are optional for the sensitivity theorist.

The paper discusses some themes in Duncan Pritchard’s last book, Epistemic Angst. Radical Skepticism and the Groundlessness of Our Believing. It considers it in relation to other forms of Wittgenstein-inspired hinge-epistemology. It focuses, in particular, on the proposed treatment of Closure in relation to entailments containing hinges, the treatment of Underdetermination-based skeptical paradox and the avail to disjunctivism to respond to the latter. It argues that, although bold and thought-provoking, the mix of hinge epistemology and disjunctivism Pritchard proposes is not (...) motivated. (shrink)

_ Source: _Volume 7, Issue 4, pp 281 - 295 The paper contains the replies to the comments made by Alan Millar, Yuval Avnur, Giorgio Volpe, and Maria Baghramian on my _Extended Rationality: A Hinge Epistemology_. It addresses, in particular, the nature of perceptual justification, the truth of hinges, my response to Humean skepticism and the issue of epistemic relativism.

Hinge epistemology has to dispel the worry that disagreeing over hinges is rationally inert. Building on a companion piece (Coliva and Palmira 2020), this paper offers a constitutivist solution to the problem of rational inertia by maintaining that a Humean sceptic and a hinge epistemologist disagree over the correct explication of the concept of epistemic rationality. The paper explores the implications of such a solution. First, it clarifies in what sense a disagreement over hinges would be a conceptual disagreement. Secondly, (...) it uses considerations about the (alleged) rational inertia of hinge disagreement to offer a test whereby to demarcate genuine hinges from merely entrenched beliefs. Thirdly, it offers a response to the challenge of explaining why we have reason to engage in the epistemic practices that hinges are constitutive of in the first place. Fourthly, it argues that the constitutivist approach to hinge disagreement does not result in a relativist view. (shrink)

What cognitive goods do children plausibly have a right to in an education? In attempting to answer this question, I begin with a puzzle centred around Feinberg’s observation that a denial of certain cognitive goods can violate a child’s right to an open future. I show that propositionalist, dispositionalist and objectualist characterisations of the kinds of cognitive goods children have a right to run in to problems. A promising alternative is then proposed and defended, one that is inspired in the (...) main by Wittgenstein’s ‘hinge’ epistemology as developed in his posthumous On Certainty. (shrink)

One notable line of argument for epistemic relativism appeals to considerations to do with non-neutrality: in certain dialectical contexts—take for instance the famous dispute between Galileo and Cardinal Bellarmine concerning geocentrism—it seems as though a lack of suitably neutral epistemic standards that either side could appeal to in order to resolve their first-order dispute is itself—as Rorty influentially thought—evidence for epistemic relativism. In this essay, my aim is first to present a more charitable reformulation of this line of reasoning, one (...) that is framed not merely in terms of the availability of epistemic norms that are suitably neutral between interlocutors, but in terms of the availability of what I call Archimedean metanorms. Once this more charitable line of argument is developed, I show how, even though it avoids problems that face ‘non-neutrality’ versions of the argument, it nonetheless runs into various other problems that appear ultimately intractable and, further, that the strategy in question gives us no decisive reason to draw the relativist’s conclusion rather than the Pyrrhonian sceptic’s.

Pragmatic theories of truth need to pass the pragmatic test: they need to make a difference. Unfortunately, defenders of the pragmatic theory have rarely applied this test. I argue that a Deweyan pragmatic account of truth passes the test by identifying the political and epistemic dangers of certain types of social networks that create a durable consensus around false beliefs. To better understand Dewey’s account of truth I propose an excursion through Wittgenstein’s later views on knowledge and certainty.

The paper introduces a new problem for fallibilist and infallibilist epistemologies – the diachronic threshold problem. As the name suggests, this is a problem similar to the well–known threshold problem for fallibilism. The new problem affects both fallibilism and infallibilism, however. The paper argues that anyone who worries about the well known problem for fallibilism should also worry about this new, diachronic version of the problem.

Recently, hinge epistemologists have applied Wittgenstein’s metaphor of hinges to religious belief. The most prominent proposal in this context is Pritchard’s “quasi-fideism”. This paper examines some historical precursors of the notion of religious hinges, with the aim of shedding more light on it. After outlining the framework of hinge epistemology and its application to religious belief, I briefly examine the views of Thomas Reid and John Henry Newman as acknowledged forerunners of this framework (or cognate views). Next, I turn to (...) two hitherto unacknowledged forerunners, the pragmatists William James and Charles S. Peirce. I then focus on some insights that the pragmatists offer. On this basis, I conclude that religious beliefs are a special class of hinges. As such, while they can be defended through hinge epistemology, they cannot constitute a model through which we can interpret the nature of hinges in general. (shrink)

Although research on epistemic injustice has focused on the effects of prejudice in epistemic exchanges, the account of prejudice that emerges in Fricker’s (2007) view is not completely clear. In particular, I claim that the epistemic role of prejudice in the structure of testimonial justification is still in need of a satisfactory explanation. What special epistemic power does prejudice exercise that prevents the speaker’s words from constituting evidence for the hearer’s belief? By clarifying this point, it will be possible to (...) address two more general issues concerning the nature of prejudice: its resistance to counterevidence and the steps involved in overcoming prejudice. I propose a hinge account of prejudice, based on the recent perspective of hinge epistemology, to help clarify these aspects. According to the hinge account, prejudices share a fundamental feature with hinges: they work as norms of evidential significance, and as such, they determine what can and cannot count as evidence for belief.

Here we show that sensitivity does not, in general, violate closure.

I have long admired the work of Jennifer Nagel, Ram Neta, and Duncan Pritchard. Each of them is an extremely impressive philosopher from whom I’ve learned much over the years. To have the three of them participating in this symposium on my book, "Radical Skepticism and Epistemic Intuition", is a great honor as well as a delight. Many thanks to each of them for taking the time to read my book and to write up such excellent, challenging, and helpful comments. (...) I won’t be able to address everything they say, but I’ll try to address their main concerns in the space available. (shrink)

ABSTRACTThis article intends to reconsider the epistemological status of delusional beliefs on the basis of Wittgenstein’s conception of certainty. Several works over the last two decades have compared delusional beliefs with so-called hinge propositions, which – according to Wittgenstein – function as expressions of objective certainty. This gives rise to a paradox. On the one hand, delusions are compatible to Wittgensteinian certainties in some respects; on the other hand, they contradict beliefs shared by other members of the community, which makes (...) them different from ‘normal’ certainties. In order to address this issue, I use Moyal-Sharrock’s taxonomy of hinge propositions. This taxonomy allows one to distinguish between different types of hinge propositions; all types share the same features, but these features are manifested in a variety of ways. Thus, delusional beliefs might also be regarded as constituting a specific type of hinge propositions. This move makes it possible to resolve the paradox and to identify the special epistemic features of delusional beliefs. (shrink)

The paper articulates a novel strategy against external world skepticism. It shows that a modal assumption of the skeptical argument cannot be justified.

The problem of skepticism is often understood as a paradox: a valid argument with plausible premises whose conclusion is that we lack justification for perceptual beliefs. Typically, this conclusion is deemed unacceptable, so a theory is offered that posits conditions for justification on which some premise is false. The theory defended here is more general, and explains why the paradox arises in the first place. Like Strawson’s (Introduction to logical theory, Wiley, New York, 1952) “ordinary language” approach to induction, the (...) theory posits something built into the very notion of justification: it is loaded with a bias towards the proposition that we are not massively deceived. Beyond the paradox, remaining skeptical problems consist of metaphysical and practical questions: whether we are massively deceived, or why we should use our loaded notion rather than some other. Such challenges have pro- found epistemological significance, but they are not problems that an a priori theory of justification can solve. (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)

Uno de los cargos habituales contra el proyecto epistemológico cartesiano consiste en señalar que su principal objetivo y los medios para alcanzarlo son incompatibles, de forma que el método bloquea ab initio su propia función. En este artículo argumento que dicha acusación solo es plausible al precio de ignorar tanto la naturaleza terapéutica del método cartesiano como los procedimientos concretos que Descartes emplea para alcanzar una posiciónepistémica desde la que las hipótesis escépticas radicales dejan de tener sentido. La estrategia antiescéptica (...) cartesiana compite con ventaja con procedimientos rivales contemporáneos, se trate de estrategias externistas de orden revisionista o de estrategias de minimización del escepticismo que acentúen el carácter a-racional de nuestras creencias fundacionales.

An overview of the ancient philosophers and their philosophical system (divided into the fields of logic, physics, and ethics) comprising the living, organic, enduring, and evolving body of interrelated ideas identifiable as the Stoic perspective.

n the first part of the paper I will present Pritchard’s approach to Wittgenstein’s notion of hinge commitments, which is essential to his solution to the closure-based sceptical arguments. And, in the second par of the paper, I will raise some concerns that I have regarding Pritchard’s non-belief reading of the hinge commitments. In the third and final part, I make some concluding remarks regarding Pritchard’s overall strategy to solve the closure-based sceptical paradox.

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

What is it that we are doing when we make ethical claims and judgments, such as the claim that we morally ought to assist refugees? This dissertation introduces and defends a novel theory of ethical thought and discourse. I begin by identifying the surface features of ethical thought and discourse to be explained, including the realist and cognitivist (i.e. belief-like) appearance of ethical judgments, and the apparent close connection between making a sincere ethical judgment and being motivated to act on (...) it. I examine prominent attempts to explain these features, with a focus on recent ‘hybrid’ theories combining elements of expressivism and cognitivism. Despite their initial promise, I argue that extant hybrid theories are nevertheless committed to problematic semantic, metasemantic, or pragmatic assumptions. I then discuss what I take to be the strongest existing option, ethical neo-expressivism (Bar-On and Chrisman, 2009; Bar-On, Chrisman, and Sias, 2014), and develop it into an explicitly hybrid theory proposing that ethical judgments incorporate both motivationally-charged affective states and moral beliefs. I then supplement this account with a theory of the proper function (following Millikan, 1984) of ethical claims and judgments, arguing that they function simultaneously to track the morally salient features of social situations, and to coordinate our behavior around these features. Finally, I defend one of the cognitivist commitments of the theory – namely, that objective moral knowledge is possible – by applying recent work on the epistemology of fundamental or ‘core’ intellectual commitments (Lynch, 2012; Pritchard, 2016) to the moral realm.

It is claimed that the radical sceptical problem that is the focus of much of contemporary epistemological discussion in fact divides into two logically distinct subproblems --a formulation that turns on the closure principle, and a second formulation which turns on the underdetermination principle. The Wittgensteinian account of the structure of rational evaluation is set out, and it is shown how this proposal --at least when properly formulated--can deal with closure-based radical scepticism. It is also claimed, however, that this account (...) fails to gain any purchase on underdetermination-based radical scepticism. The antidote to this latter form of radical scepticism lies elsewhere--with, it is suggested, epistemological disjunctivism. (shrink)

An orthodox sceptical hypothesis claims that one’s belief that “I am not a brain-in-a-vat (BIV)” (or any other ordinary anti-sceptical belief) is insensitive. A form of sensitivity-based scepticism, can thus be constructed by combining this orthodox hypothesis with the sensitivity principle and the closure principle. Unlike traditional solutions to the sensitivity-based sceptical problem, this paper will propose a new solution—one which does not reject either closure or sensitivity. Instead, I argue that sceptics’ assumption that one’s ordinary anti-sceptical beliefs are insensitive (...) will give rise to self-contradiction. The orthodox sceptical hypothesis is thus revealed to be incoherent and arbitrary. Given that there is no coherent reason to presuppose our ordinary anti-sceptical beliefs to be insensitive, the argument for sensitivity-based scepticism can thus be blocked at a lower epistemological cost.

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.

This is a critical commentary on Pritchard's book Epistemic Angst. In Section 2, I present the closure-based radical skeptical paradox. Then in Section 3, I sketch Pritchard’s undercutting response to this paradox. Finally, in Section 4, I put forward two concerns about Pritchard’s response and I also propose a reading of hinge commitments, the ability reading, that might put some pressure on Pritchard’s own reading of these commitments.

This paper focuses on a potential problem with Sosa’s theory of default assumption, viz., the alleged incompatibility of this theory with the closure principle. Given the similarity between the notion of default assumption and Wittgenstein’s notion of hinge commitment, I suggest that two influential hinge epistemologies including Wright’s entitlement theory and Pritchard’s non-belief theory provide resources for possible solutions to the problem. I argue that default assumption should be classified as acceptance and hence as a non-doxastic propositional attitude. Sosa’s theory (...) can deal with the apparent incompatibility with the closure principle by adopting the solution of the non-belief theory, while also avoiding problems affecting the latter view.

Questions about the possibility of thought as an activity directed to reality, are deeper than those concerning the possibility of knowledge. These deeper questions have found intuitive expression in the Agrippan Trilemma, particularly in the trope of arbitrary presupposition. This trope can be raised as a criticism of current varieties of hinge epistemology inspired by Wittgenstein, mainly by virtue of the fact that Wittgensteinian hinges are foundational principles governing our epistemic practice. As such, they are necessarily unsupportable, being thus dificult (...) to see how it would be possible to conciliate the hinges’ lack of support with their being not bare, arbitrary assertions. Facing up to this challenge, hinge epistemologists have proposed practical --though not pragmatic-- arguments according to which hinges are either postulates legitimately demanded to every epistemic agent or rules constitutive of quotidian practices. It is the aim of this article to show that practical arguments for hinges fall short, necessarily so. (shrink)
