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)

My aims are exegetical rather than critical: I offer a systematic account of Hursthouse's ethical naturalism with an emphasis on the normative authority of the four ends, and try to correct some misconceptions found in the literature. Specifically, I argue that the four ends function akin to Wittgensteinian hinge-propositions for our practice of ethical reasoning and as such form part of a description of the logical grammar of said practice.

We review the "Entitlement" projects of Tyler Burge and Crispin Wright in light of recent work from and surrounding both philosophers. Our review dispels three misunderstandings. First, Burge and Wright are not involved in a common “entitlement” project. Second, though for both Wright and Burge entitlement is the new notion, “entitlement” is not some altogether third topic not clearly connected to the nature of knowledge or the encounter with skepticism. Third, entitlement vs. justification does not align with the externalism vs. (...) internalism distinction. (shrink)

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.

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.

Common knowledge is ubiquitous in our lives and yet there remains considerable uncertainty about how to model or understand it. Standard analyses of common knowledge end up being challenged by either regress or circularity which then give rise to well-known paradoxes of practical reasoning, such as the Two Generals’ Paradox. This paper argues that the nature and utility of common knowledge can be illuminated by appeal to Wittgenstein’s Hinge Epistemology. It is argued that those things that we standardly think of (...) as being common knowledge in our lives are the same as those that Wittgenstein identified as hinge certainties. This identification of common knowledge with hinge certainties allows us to resolve the regress problem for common knowledge and explain how the Two Generals’ Paradox arises. (shrink)

The influence of Wittgenstein’s work in the study of deep disagreements has been dominated by On Certainty. Since the metaphor of ‘hinges’ plays a central role in the scholarship of On Certainty, a Wittgensteinian theory of deep disagreements is assumed to be based on hinge epistemology. This means that a disagreement would be deep because it concerns parties with conflicting hinges. When we shift our attention to a different part of Wittgenstein’s oeuvre, however, another picture of deep disagreements emerges. This (...) article proposes a new Wittgensteinian approach to disagreements through the analysis of the Lectures on Religious Belief. Some of the disagreements that Wittgenstein and his pupils discuss in these lectures are deep, but not because they are grounded in different hinges, but because they are disagreements about pictures.

Open-mindedness appears as a potential intellectual virtue from the beginning of the rise of the literature on intellectual virtues. It often takes up a special role, sometimes thought of as a meta-virtue rather than a first-order virtue: as an ingredient that makes other virtues virtuous. Jason Baehr has attempted to give a unified account of open-mindedness as an intellectual virtue. He argues that the conceptual core of open-mindedness lies in the fact that a person departs, moves beyond, or transcends a (...) certain default cognitive standpoint. Two of his main aims are to show that (1) one does not need to assume a doxastic conflict or disagreement to be at the heart of open-mindedness—that is, there are also instances where the virtue of open-mindedness is needed when there is no opposing view to be considered—and (2) that not all forms of open-mindedness include rational assessment—that is, sometimes being open-minded is not about weighing evidence for and against a claim. So, his main aim is to show that there are various situations that afford open-mindedness, in each of which a slightly different kind of open-mindedness is called for. To unify all these different kinds of open-mindedness is then the goal of his work. He arrives at the following definition of open-mindedness (OM): an open-minded person is characteristically (a) willing and (within limits) able (b) to transcend a default cognitive standpoint (c) in order to take up or take seriously the merits of (d) a distinct cognitive standpoint. In this article, I take seriously Baehr’s suggestion of how to understand open-mindedness as an intellectual virtue and argue that the crux lies in formulating how we can be able to transcend a default cognitive standpoint. This is not as obvious as it has been taken to be in the literature on open-mindedness. Biases, overconfidence, and wishful thinking are difficult exactly because we don’t know that we are engaging in them. That is, they are systematically hidden from our consciousness, otherwise they would not be a bias, overconfidence, or wishful thinking. Hence, the crux of making open-mindedness open-minded is to see how it is possible to make something of one’s own mind visible that is systematically hidden from oneself. I argue that this problem can be solved by looking at research on attention. I base my considerations in this article on Sebastian Watzl’s account of attention, which essentially holds that paying attention is an activity of foregrounding and backgrounding mental contents. That is, attention is the activity of structuring mental contents into a priority structure of foreground and background. If I pay attention to the scene in front of me, I foreground the black letters on my screen, and I background the coffee cup next to them. In this way, I create a priority structure between the letters (as they appear to me) and the coffee cup (as it appears to me). I argue that what allows us to make something of our own mind visible that is systematically hidden from us is a special way of paying attention, hence a special way of foregrounding and backgrounding the involved mental contents. That is, the crux of what enables us to transcend a default cognitive standpoint, the conceptual core of open-mindedness, is a special kind of attention, which I will call ‘open-minded attention’ (OMA). The claim of this article is not that open-minded attention fully describes the virtue of open-mindedness (OMA is not sufficient for open-mindedness). Rather, what I try to show is that in all cases of open-mindedness it turns out that open-minded attention is the necessary component that ensures that we can indeed get rid of prior biases, that is, transcend also those implicit beliefs and expectations that are systematically hidden from us (OMA is necessary for open-mindedness).

Some philosophers have argued that Wittgenstein’s hinges, the centrepiece of his book On Certainty, are the “ungrounded ground” on which knowledge rests. It is usually understood by this that hinges provide a foundation for knowledge without being themselves epistemically warranted. In fact, Wittgenstein articulates that hinges lack any truth-value and are neither justified nor unjustified. This inevitably places them wholly outside the categorial framework of JTB epistemology. What I call the “groundlessness interpretation”, inspired by OC 166, understands the fundamental pieces (...) of our cognitive scaffolding this way. The view has been largely successful. I argue that this interpretation is incomplete for two basic reasons: first, it is not based on undisputed evidence; second, by assuming that hinges are committed to reality by epistemic fiat, it looks as if Wittgenstein is asking us to blindly trust them regardless of their actual content. Contrary to this, I argue that Wittgenstein describes hinges as illuminating world-pictures that reflect reality and are answerable to facts in a derivate way. As the book shows, hinges originate in our engagement with reality and, while considered unquestionable, could be challenged, reassessed, and replaced by new ones. This indicates that hinges are both the result of knowledge-acquisition and somewhat continuous with one’s set of beliefs. It follows that hinges are ultimately rational, and so, apt instruments to confront scepticism. (shrink)
