The general topic of skepticism crops up in Wittgenstein's work, from his remarks on solipsism in the Tractactus, to the potentially skepticism‐inducing claims about rule‐following in Philosophical Investigations. Wittgenstein's radical new conception of the structure of rational evaluation blocks even this route to radical skepticism, since it excludes the possibility that the radical skeptic's wholesale rational evaluations could constitute a purified version of our everyday local rational evaluations. According to epistemic externalism, knowledge can be sometimes 'brute', at least from a (...) rational point of view. Given the problems facing the externalist and entitlement proposals, one might be tempted to adopt a more radical proposal, one that is arguably closer in spirit to what Wittgenstein himself intended. According to this proposal, we need to take very seriously how Wittgenstein talks of these commitments as being utterly visceral in nature and conclude on this basis that such commitments simply are not in the market for knowledge.

This paper aims to motivate a scepticism about scepticism in contemporary epistemology. I present the sceptic with a dilemma: On one parsing of the BIV (brain-in-a-vat) scenario, the second premise in a closure-based sceptical argument will turn out false, because the scenario is refutable; on another parsing, the scenario collapses into incoherence, because the sceptic cannot even save the appearances. I discuss three different ways of cashing out the BIV scenario: ‘Recent Envatment’ (RE), ‘Lifelong Envatment’ (LE) and ‘Nothing But Envatment’ (...) (NBE). I show that RE scenarios are a kind of ‘local’ sceptical scenario that does not pose a significant threat to the possibility of perceptual knowledge as such. I then go on to consider the more radical (or global) LE and NBE scenarios, which do undermine the possibility of perceptual knowledge of an ‘external’ world by positing that it is conceivable that one has always been envatted and, hence, trapped in a ‘global’ illusion. I start by assuming that we could be in such a scenario (LE or NBE) and then spell out what we would need to presuppose for such scenarios to be capable of being actual. Drawing on some central insights from Wittgenstein’s anti-private language considerations, I show that the truth of a global scepticism would presuppose the possibility of a private ‘vat-language’, a notion that cannot be rendered coherent. But, if so, then neither can the sceptical scenarios that presuppose such a conception. (shrink)

_ Source: _Volume 6, Issue 2-3, pp 165 - 181 Wittgenstein’s notion of ‘hinge propositions’—those propositions that stand fast for us and around which all empirical enquiry turns—remains controversial and elusive, and none of the recent attempts to make sense of it strike me as entirely satisfactory. The literature on this topic tends to divide into two camps: either a ‘quasi-epistemic’ reading is offered that seeks to downplay the radical nature of Wittgenstein’s proposal by assimilating his thought to more mainstream (...) epistemological views, or a non-epistemic, ‘quasi-pragmatic’ conception is adopted that goes too far in the opposite direction by, for example, equating ‘hinge propositions’ with a type of ‘animal’ certainty. Neither interpretative strategy, I will argue, is promising for the reason that ‘hinges’ are best not conceived as certainties at all. Rather, what Wittgenstein says in respect to them is that doubt is “logically” excluded, and where there can be no doubt, I contend, there is no such thing as knowledge or certainty either. (shrink)

Genia Schönbaumsfeld has recently argued for the view that our ordinary perceptual reasons provide support for heavyweight metaphysical and epistemological views, such as that there is a mind-independent physical world. Call this the Heavyweight Reasons Thesis. In this paper, I argue that we should reject the Heavyweight Reasons Thesis. I also argue that the rejection of the Heavyweight Reasons Thesis is compatible with the Factive Perceptual Reasons Thesis, the thesis that our perceptual reasons for our ordinary beliefs can be factive, (...) but that factive reasons aren’t necessarily better reasons than subjectively indiscriminable non-factive reasons.

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. (shrink)

The axiological account of deep disagreements is described and defended. This proposal understands this notion in terms of the existential importance of the topic of disagreement. It is argued that this account provides a straightforward explanation for the main features of deep disagreements. This proposal is then compared to the contemporary popular view that deep disagreements are essentially hinge disagreements – i.e. disagreements concerning clashes of one’s hinge commitments, in the sense described by the later Wittgenstein. It is claimed that (...) hinge disagreements are only plausibly deep disagreements insofar as there can be a specific class of hinge commitments that are axiological in nature, thereby lending further support to the axiological account of deep disagreement.

Part one offers a précis of my book, Epistemic Angst, with particular focus on the themes discussed by the participants in this symposium. Part two then examines a number of topics raised in this symposium in light of this précis. These include how best to understand the ‘non-belief’ account of hinge epistemology, whether we should think of our hinge commitments as being a kind of procedural knowledge, whether hinge epistemology can be used to deal with underdetermination-based scepticism, what the status (...) of my acceptance of the closure principle amounts to, whether one’s total evidence in fact supports our hinge commitments, and the nature of the kind of reasoning that Wittgenstein employs when advancing a hinge epistemology. Finally, I offer some remarks on the notion of epistemic risk in the context of the sceptical problematic, and show how this has application to legal epistemology. (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)

My interest is in the relationship between the contemporary account of the epistemology of religious belief, known as quasi-fideism, and the sceptical fideism that has been so important, historically, in motivating fideistic ideas. I argue that we can profitably construe quasi-fideism along sceptical fideist lines, in that it is a proposal that is naturally understood as both arising within the context of a sceptical investigation and as exhibiting core features that it shares with Pyrrhonian scepticism. Moreover, I suggest that sceptical (...) fideism, properly rendered, is inclined towards the kind of restricted fideism that is essential to quasi-fideism. (shrink)

God’s omniscience generates certain puzzles, not least regarding how such omniscience is compatible with human free will. One option in this regard is to impose limitations on the scope of God’s knowledge, but that then poses the further question of how such limitations can be compatible with God’s nature as a perfect being. I offer a novel way of approaching these questions, which appeals to what I claim is an independently motivated distinction between lacking knowledge and being ignorant. In particular, (...) it is contended that God’s omniscience is best understood not as a complete knowledge of all truths, but rather as a kind of deliberate non-knowing that excludes ignorance. God might not know all truths, but that’s not because of any cognitive lack, and there is certainly no truth about which he is ignorant. (shrink)

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.

My interest is the kind of philosophical vertigo that is a theme of Cavell’s work on scepticism. This describes the anxiety that is elicited via philosophical engagement with certain kinds of sceptical questions. There is a standing puzzle about this notion of vertigo, however, forcefully pressed, for example, by McDowell. Why should a resolution of the sceptical problem, one that putatively completely undercuts the motivation for scepticism in that domain, nonetheless generate vertigo in this sense? I aim to resolve the (...) puzzle, in a way that I believe underwrites this Cavellian notion, via consideration of Wittgenstein’s remarks on the structure of rational evaluation in his final notebooks, published as On Certainty.

This paper clarifies Wittgenstein’s critique of Moore in _On Certainty,_ and argues that this critique is largely misunderstood, for two reasons. Firstly, Wittgenstein partly misrepresents Moore. Secondly, Wittgenstein is wrongly taken to be an internalist regarding justification for knowledge. Once we realize these two points, we can understand Wittgenstein’s critique properly as a grammatical argument in that Moore fails to see how the concepts of knowledge and certainty relate to those of justification and evidence. On this reading, we can also (...) understand that Moore and Wittgenstein were in more agreement than many people have thought, even though Moore was not able to exploit and express his philosophical insights properly.

Annalisa Coliva (Int J Study Skept 10(3–4):346–366, 2020) asks, “Are there mathematical hinges?” I argue here, against Coliva’s own conclusion, that there are. I further claim that this affirmative answer allows a case to be made for taking the concept of a hinge to be a useful and general-purpose tool for studying mathematical practice in its real complexity. Seeing how Wittgenstein can, and why he would, countenance mathematical hinges additionally gives us a deeper understanding of some of his latest thoughts (...) on mathematics. For example, a view of how mathematical hinges relate to Wittgenstein’s well-known river-bed analogy enables us to see how his way of thinking about mathematics can account nicely for a “dynamics of change” within mathematical research—something his philosophy of mathematics has been accused of missing (e.g., by Robert Ackermann (Wittgenstein’s city, The University of Massachusetts Press, Amherst, 1988) and Mark Wilson (Wandering significance: an essay on conceptual behavior, Oxford University Press, Oxford, 2006). Finally, the perspective on mathematical hinges ultimately arrived at will be seen to provide us with illuminating examples of how our conceptual choices and theories can be ungrounded but nevertheless the right ones (in a sense to be explained).

The purpose of this paper is to provide a new solution to the radical sceptical paradox. A sceptical paradox purports to indicate the inconsistency within our fundamental epistemological commitments that are all seemingly plausible. Typically, sceptics employ an intuitively appealing epistemic principle (e.g., the closure principle, the underdetermination principle) to derive the sceptical conclusion. This paper will reveal a dilemma intrinsic to the sceptical paradox, which I refer to as the self-hollowing problem of radical scepticism. That is, on the one (...) hand, if the sceptical conclusion turns out to be true, then the epistemic principle employed by sceptics would lose its foundation of plausibility; on the other hand, if the sceptical conclusion does not follow, then the sceptical problem would not arise. In either case, the so-called sceptical paradox cannot be a genuine paradox. This new solution has three theoretical merits: it is undercutting, less theory-laden, and widely applicable. (shrink)

This paper seeks to widen the dialogue between the “epistemology of peer disagreement” and the epistemology informed by Wittgenstein’s last notebooks, later edited as On Certainty. The paper defends the following theses: not all certainties are groundless; many of them are beliefs; and they do not have a common essence. An epistemic peer need not share all of my certainties. Which response to a disagreement over a certainty is called for, depends on the type of certainty in question. Sometimes a (...) form of relativism is the right response. Reasonable, mutually recognized peer disagreement over a certainty is possible.—The paper thus addresses both interpretative and systematic issues. It uses Wittgenstein as a resource for thinking about peer disagreement over certainties. (shrink)

Scepticism and negative theology are best understood not as theoretical positions, but rather as forms of philosophical practice that performatively undermine our knowledge claims or our seeming understanding of God. In particular, I am arguing that both scepticism and negative theology invoke the failure of the attempt to understand the absolute, be it God or the notion of absolute objectivity. However, with reference to L. A. Paul’s notion of epistemically transformative experience, I am arguing that we still understand something about (...) the absolute through the experience of failing to think it. This, of course, is a non-propositional form of understanding, and I am arguing that there is something about the finitude of the human condition that can only be understood through a transformative philosophical experience with respect to the absolute.

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)

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.

The skeptical challenge to politics is that if knowledge is in short supply and it is a condition for the proper use of political power, then there is very little just politics. Cicero’s Republicanism is posed as a program for political legitimacy wherein both citizens and their states are far from ideal. The result is a form of what is termed negative conservatism, which shows political gridlock in a more positive light.

Wittgenstein's 'plan for the treatment of psychological concepts' in the second volume of his Remarks on the Philosophy of Psychology (§§63, 148) is often understood as motivated by purely classificatory concerns that have little philosophical significance. I argue that this is a misinterpretation of Wittgenstein and that his planned and partly realized 'treatment of psychological concepts' deserves a better fate. In the first part of the paper I attempt to show that Wittgenstein's interest in psychological concepts in RPPII, far from (...) being merely an interest in their classification, is in fact closely connected to one important element of his conception of philosophy in the Philosophical Investigations, the requirement that 'all explanation must disappear, and description alone must take its place' (PI §109). In the second part of the paper I present the broad outlines of Wittgenstein's new, post-Investigations treatment of psychological concepts, as they are seen both in the account of the concepts directly addressed in RPPII §§63, 148 (those of seeing and other sense-impressions, of sensations, mental images and emotions), and also elsewhere in that volume where other important psychological concepts are discussed, e.g., those of thinking, intention and states of mind (Seelenzustande). Although it represents work in progress that was never brought to completion, I suggest that the account of psychological concepts in RPPII is an original, insufficiently appreciated strand of thought within Wittgenstein's oeuvre, and also that it is an account worth exploring for anyone not convinced by the scientism accepted by so much of the recent philosophy of mind.

In this paper, I argue that hinge propositions are ways of acting that constitute abilities or skills. My starting point is Moyal-Sharrock's account of hinge propositions. However, Moyal-Sharrock's account leaves gaps to be filled, as it does not offer a unified explanation of the origin of our ungrounded grounds. Her account also lacks resources to respond to the issue of demarcation, since it does not provide a criterion for distinguishing ways of acting that can legitimately fulfill the role of ungrounded (...) grounds from those that cannot. Without an answer to this issue, the relativistic threat is serious. I then propose that by narrowing the ways of acting to those that are constitutive of abilities, we can deal with the relativistic threat. I provide an ecological approach to abilities through which I explain why abilities are reality-soaked and therefore why the ways of acting that constitute them are legitimate ungrounded grounds. Based on that approach, I provide an answer to the issue of demarcation that defuses the relativistic threat. (shrink)

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)

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.
