The traditional epistemological problem of other minds seeks to answer the following question: how can we know someone else's mental states? The problem is often taken to be generated by a fundamental asymmetry in the means of knowledge. In my own case, I can know directly what I think and feel. This sort of self-knowledge is epistemically direct in the sense of being non-inferential and non-observational. My knowledge of other minds, however, is thought to lack these epistemic features. So what (...) is the basic source of my knowledge of other minds if I know my mind in such a way that I cannot know the minds of others? The aim of this paper is to clarify and assess the pivotal role that the asymmetry in respect of knowledge plays within a broadly inferentialist approach to the epistemological problem of other minds. The received dogma has always been to endorse the asymmetry for conceptual reasons and to insist that the idea of knowing someone else's mental life in the same way as one knows one's own mind is a complete non-starter. Against this, I aim to show that it is at best a contingent matter that creatures such as us cannot know other minds just as we know a good deal of our own minds and also that the idea of having someone else's mind in one's own introspective reach is not obviously self-contradictory. So the dogma needs to be revisited. As a result, the dialectical position of those inferentialists who believe that we know about someone else's mentality in virtue of an analogical inference will be reinforced. (shrink)

The notion of cognitive act is of importance for an epistemology that is apt for constructive type theory, and for epistemology in general. Instead of taking knowledge attributions as the primary use of the verb 'to know' that needs to be given an account of, and understanding a first-person knowledge claim as a special case of knowledge attribution, the account of knowledge that is given here understands first-person knowledge claims as the primary use of the verb 'to know'. This means (...) that a cognitive act is an act that counts as cognitive from a first-person point of view. The method of linguistic phenomenology is used to explain or elucidate our epistemic notions. One of the advantages of the theory is that an answer can be given to some of the problems in modern epistemology, such as the Gettier problem. (shrink)

How must knowledge be formed, if made in the image of assertion? That is, given that knowledge plays the normative role of governing what one may assert, what can be inferred about the structure of the knowledge relation from this role? I will argue that what one may assert is sensitive to the question under discussion, and conclude that what one knows must be relative to a question. In short, knowledge in the image of assertion is question-relative knowledge.

Contextualism treats ‘knows’ as an indexical that denotes different epistemic properties in different contexts. Contrastivism treats ‘knows’ as denoting a ternary relation with a slot for a contrast proposition. I will argue that contrastivism resolves the main philosophical problems of contextualism, by employing a better linguistic model. Contextualist insights are best understood by contrastivist theory.

Knowledge ascriptions seem context sensitive. Yet it is widely thought that epistemic contextualism does not have a plausible semantic implementation. We aim to overcome this concern by articulating and defending an explicit contextualist semantics for ‘know,’ which integrates a fairly orthodox contextualist conception of knowledge as the elimination of the relevant alternatives, with a fairly orthodox “Amherst” semantics for A-quantification over a contextually variable domain of situations. Whatever problems epistemic contextualism might face, lack of an orthodox semantic implementation is not (...) among them. (shrink)

In the following I discuss the debate between epistemological internalists and externalists from an unfamiliar meta-epistemological perspective. In doing so, I focus on the question of whether rationality is best captured in externalist or internalist terms. Using a conception of epistemic judgments as “doxastic plans,” I characterize one important subspecies of judgments about epistemic rationality—focusing on the distinctive rational/functional role these judgments play in regulating how we form beliefs. Then I show why any judgment that plays this role should be (...) expected to behave the manner internalists predict. In this way, I argue, we can explain why our basic toolbox for epistemic evaluation includes an internalist conception of rationality. (shrink)

Suppose that Ann says, “Keith knows that the bank will be open tomorrow.” Her audience may well agree. Her knowledge ascription may seem true. But now suppose that Ben—in a different context—also says “Keith knows that the bank will be open tomorrow.” His audience may well disagree. His knowledge ascription may seem false. Indeed, a number of philosophers have claimed that people’s intuitions about knowledge ascriptions are context sensitive, in the sense that the very same knowledge ascription can seem true (...) in one conversational context but false in another. This purported fact about people’s intuitions serves as one of the main pieces of evidence for epistemic contextualism. (shrink)

A central problem for any truthmaker theory is the problem of negative truths. In this paper, I develop a novel, piecemeal strategy for solving this problem. The strategy puts central focus on a truth-relevant notion of aboutness within a metaphysically modest version of truthmaker theory and uses key conceptual tools gained by taking a deeper look at the best attempts to solve the problem of intentionality. I begin this task by critically discussing past proposed solutions to P-NEG in light of (...) Russell’s debate with Demos. This reveals a central difficulty with addressing the problem, specifically that one cannot be committed to incompatibility facts in one’s account of negation and of the truth of negative truths. I then present an aboutness-based version of truthmaker theory. Utilising what I call the strict and full account of aboutness, I extract aboutness-based theories of truth and falsity. I use this machinery to present a promising new strategy for solving P-NEG which does not have the problems of alternative approaches. Finally, I present and respond to some potential objections.

The force of sceptical inquiries into out knowledge of other people is a paradigm of the force that philosophical views can have. Sceptical views arise out of philosophical inquiries that are identical in all major respects with inquiries that we employ in ordinary cases. These inquiries employ perfectly mundane methods of making and assessing claims to know. This paper tries to show that these inquiries are conducted in cases that lack certain contextual ingredients found in ordinary cases. The paper concludes (...) that these ordinary methods of inquiry, when employed in these limited cases, put us in a position in which we actually cannot know. Thus our ability to know will be a function of the added contextual elements that are found in ordinary cases. A second conclusion is that we come literally to observe bodily behaviour in the course of the sceptical inquiry; while in ordinary cases we observe pain-behaviour. (shrink)

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.

Moore’s paradox occurs with sentences, such as (1) It’s raining and I don’t think it’s raining. which are self-defeating in a way that prevents one from making an asser- tion with them.1 But Mark Crimmins has given us a case of a sentence that is syntactically just like (1) but is nonetheless assertible. Suppose I know somebody, and know or have excellent reason to believe that I know that very person under some other guise. I do not know what that (...) other guise is, though I do know that I believe that the person I know under that other guise is an idiot. (shrink)

Gareth Evans famously affirmed an explanatory connection between answering the question whether p and knowing whether one believes that p. This is commonly interpreted in terms of the idea that judging that p constitutes an adequate basis for the belief that one believes that p. This paper formulates and defends an alternative, more modest interpretation, which develops from the suggestion that one can know that one believes that p in judging that p.

This paper introduces the Special Issue on 'post-truth'. The contributions to this special issue try between them to strike a right balance. To establish how new ‘post-truthism’ really is – or isn’t. To seek a point of reflection on whatever is new in our current socio-political straits. And to consider seriously how philosophy can help. Whether by wondering about the extent to which reason, or truth, may rightly, if one follows Wittgenstein, be viewed in certain respects as a constraint upon (...) thought or opinion. Or indeed by wondering whether we still have a long way to go in approaching truth at all. (shrink)

Recent work on the development of a dialogical approach to the logic of fiction stresses the notion of existence as choice. Moreover, this approach to existence has been combined with the notion of ontolog-ical dependence as deployed by A. Thomasson’s artifactual theory of fiction. In order to implement such a combination within the dialogical frame several predicates of ontological dependence have been de-fined. However, the definition of such predicates seems to lean on a model-theoretic semantics for mod-al logic after all. (...) The main aim of the present paper is to set a dialogical frame for the study of fictions in the context of the dialogical approach of CTT recently developed by S. Rahman and N. Clerbout where a fully-interpreted language is unfolded. We will herewith develop the idea that in such a setting fiction-al entities are understood as hypothetical objects, that is, objects (functions) the existence of which is dependent upon one or more hypotheses that restrict the scope of choices available. We will finish the paper by suggesting that this provides both a natural and genuinely dialogical way to understand R. Frigg’s take on scientific models as fictions and a new perspective on Thomasson’s notion of generic ontological dependence. Keywords: fiction, dialogues, dialogical logic, hypothetical objects, scientific models. (shrink)

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)

G. E. Moore famously offered a strikingly straightforward response to the radical sceptic which simply consisted of the claim that one could know, on the basis of one's knowledge that one has hands, that there exists an external world. In general, the Moorean response to scepticism maintains that we can know the denials of sceptical hypotheses on the basis of our knowledge of everyday propositions. In the recent literature two proposals have been put forward to try to accommodate, to varying (...) extents, this Moorean thesis. On the one hand, there are those who endorse an externalist version of contextualism, such as Keith DeRose, who have claimed that there must be some contexts in which Moore is right. More radically still, Ernest Sosa has expanded on this externalist thesis by arguing that, contra DeRose's contextualism, Moore may be right in all contexts. In this paper I evaluate these claims and argue that, suitably modified, one can resurrect the main elements of the Moorean anti-sceptical thesis. (shrink)

Following David Hitchcock and Stephen Toulmin, this paper takes warrants to be material inference rules. It offers an account of the form such rules should take that is designed (a) to implement the idea that an argument/inference is valid only if it is entitlement preserving and (b) to support a qualitative version of evidence proportionalism. It attempts to capture what gives warrants their normative force by elaborating a concept of reliability tailored to its account of the form such rules should (...) take. (shrink)

According to the perceptual model, our knowledge of others' minds is a form of perceptual knowledge. We know, for example, that Jones is angry because we can literally see that he is. In this essay, I argue that mental states do not have the kind of distinctive looks that could sufficiently justify perceptual knowledge of others’ mentality. I present a puzzle that can arise with respect to mental states that I claim does not arise for non-mental properties like being an (...) apple and argue that this is explained by the fact that the looks of non-mental properties adhere to a certain explanatory principle that does not hold for mental states. This shows, I argue, that, even if we think mental states do have looks, these cannot offer sufficient grounds for perceptual knowledge of others' minds. In the final section of the essay, I suggest an alternative way of thinking about our knowledge of others' minds and about the sorts of looks or appearances that might be associated with mental states.

Ordinarily when someone tells us something about her beliefs, desires or intentions, we presume she is right. According to standard views, this deferential trust is justified on the basis of certain epistemic properties of her assertion. In this paper, I offer a non-epistemic account of deference. I first motivate the account by noting two asymmetries between the kind of deference we show psychological self-ascriptions and the kind we grant to epistemic experts more generally. I then propose a novel agency-based account (...) of deference. Drawing on recent work on self-knowledge, I argue that a person normally has a distinctive type of cognitive agency; specifically she is able to constitute her psychological attitudes by making judgments about what they ought to be. I then argue that a speaker expresses this agentive authority when she self-ascribes a psychological attitude and this is what justifies deferentially trusting what she says. Because the notion of expression plays a central role in this account, I contrast it with recent neo-expressivist theories. (shrink)

One reason why the problem of other minds keeps cropping up in modern philosophy is that we seem to have conflicting intuitions about our access to the mental lives of others. On the one hand, we are inclined to think that it is wrong to claim, like Cartesian dualists must, that the minds of others are essentially inaccessible to direct experience. But on the other hand we feel that it is equally wrong to claim, like the behaviorists, that the mental (...) lives of others are completely accessible to an outside spectator. This paper attempts to address the problem of the accessibility of other minds while staying faithful to both these intuitions. Central to this undertaking is the idea that we express our mental lives in our bodily behavior. With a firm grasp of the notion of expression, as it is developed in the writings of Wittgenstein and Levinas, we can understand how other minds can be directly perceivable and yet retain a certain inaccessibility. The key is to emphasize the difference between the expressive appearance of a human being and the way an object appears in perception. (shrink)

I distinguish three kinds of other minds problems—conceptual, epistemological and empirical. I argue that while Merleau-Ponty believes embodiment helps with tackling the conceptual and epistemological problems, he suggests that it is of no clear use in solving the empirical problem. I sketch some considerations that could lend support to Merleau-Ponty’s claims about the conceptual and epistemological problems, without claiming that these are conclusive. I then proceed to argue that Merleau-Ponty’s take on the empirical problem is essentially correct.

The appearance in 1945 of the idea of the open texture of empirical concepts, which anticipated Friedrich Waismann’s thesis of a many-level-structure of language, led to a re-evaluation of “context”. It widens the sense of context that we are accustomed to mentioning as being Wittgenstein’s conception of meaning in his later philosophy. The new idea Waismann brought into the landscape is how to “clarify the context”, which is in a way a very non-Wittgensteinian question as well as an “explanation of (...) context”, where open texture plays a key role. But despite the amount of literature about open texture, this idea of Waismann is still not properly understood. Open texture must be situated as an obstacle to exhaustiveness of definition for internal reasons not only because of unforeseen conditions that could always arise in the future, but also by virtue of an a priori aspect of the texture of concepts. Thus, the main goal of this paper is to propose an interpretation of open texture as an immanent property of a concept, that is, as something that is underlying its nature. (shrink)

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

What is the relation between the intentionality of states and attitudes which can miss their mark, such as belief and desire, and the intentionality of acts, states and attitudes which cannot miss their mark, such as the different types of knowledge and simple seeing? Two theories of the first type of intentionality, the theory of correctness conditions and the theory of satisfaction conditions, are compared. It is argued that knowledge always involves knowledge of formal objects such as facts and values, (...) that emotions are reactions to (apparently) known values and that beliefs are reactions to known or apparently known facts or to the objects of relational states.

This article outlines a conception of perceptual-recognitional abilities. These include abilities to recognize certain things from their appearance to some sensory modality, as being of some kind, or as possessing some property. An assumption of the article is that these abilities are crucial for an adequate understanding of perceptual knowledge. The specific aim here is to contrast those abilities with abilities or competences as conceived in the virtue-theoretic literature, with particular reference to views of Ernest Sosa and John Greco. In (...) the course of the discussion, it is emphasized that the notion of exercising a perceptual-recognitional ability is a success notion: exercising such an ability is nothing less than acquiring knowledge. Even so, the view can make sense of our fallibility. It can also be defended in the face of an objection stemming from consideration of what are here called success-rate abilities. (shrink)

Arguments for scepticism about perceptual knowledge are often said to have intuitively plausible premises. In this discussion I question this view in relation to an argument from ignorance and argue that the supposed persuasiveness of the argument depends on debatable background assumptions about knowledge or justification. A reasonable response to scepticism has to show there is a plausible epistemological perspective that can make sense of our having perceptual knowledge. I present such a perspective. In order give a more satisfying response (...) to scepticism, we need also to consider the standing of background beliefs. This is required since the recognitional abilities that enable us to have perceptual knowledge are informed by, or presuppose, a picture or conception of the world the correctness of which we have not ascertained. The question is how, in the face of this, to make sense of responsible belief-formation. In addressing this problem I make a suggestion about the standing of certain crucial beliefs linking appearances with membership of kinds. (shrink)

Abstract: Some propose that the question of how you know that James is angry can be adequately answered with the claim that you see that James is angry. Call this the Perceptual Hypothesis. Here, I examine that hypothesis. I argue that there are two different ways in which the Perceptual Hypothesis could be made true. You might see that James is angry by seeing his bodily features. Alternatively, you might see that James is angry by seeing his anger. If you (...) see that James is angry in the first way, your knowledge is inferential. If you see that James is angry in the second way, your knowledge is not inferential. These are different ways of knowing that James is angry. So the Perceptual Hypothesis alone does not adequately answer the question of how you know that fact. To ascertain how you know it, we need to decide whether or not you saw his anger. This is an epistemological argument. But it has consequences for a theory of perception. It implies that there is a determinate fact about which features of an object you see. This fact is made true independently of what you come to know by seeing. In the final section of the paper, I seek to undermine various ways in which the claim that you see James' anger may be thought implausible. (shrink)

Participants on both sides of the contemporary debate between reductionism and anti-reductionism about testimony commonly describe testimonial knowledge as knowledge acquired at second hand. I argue that fully appreciating the distinctive sense in which testimonial knowledge is secondhand supports anti-reductionism over reductionism but also that it supports a particular kind of anti-reductionism very different from that typically offered in the literature. Testimonial knowledge is secondhand in the demanding sense of being justified by the authority of a speaker where this requires (...) that epistemic responsibility for meeting challenges to the audience's testimonial knowledge is shared between speaker and audience. The epistemic credentials of testimonial knowledge are in this sense importantly interpersonal. (shrink)

Consider the following proposition: It is possible that all of our perceptual experiences are ‘delusive.’ According to Gilbert Ryle, is demonstrably absurd. In this paper I address four questions: What is Ryle’s argument against?; How persuasive is it?; What positions are ruled out if is absurd?; and How does Ryle’s position compare with contemporary work on skepticism?

Analisa-se neste artigo a controvérsia protagonizada por J. Derrida e J.R. Searle acerca da obra Quando dizer é fazer de J.L.

Ela é também marcada pelo atravessamento de questões linguísticas e ontológicas relacionados à comunicação, à ação, ao sentido, à repetição, à citação etc. (shrink)

Roderick Chisholm famously held that our knowledge of the world is supported entirely by a foundation of self‐justifying statements, none of which logically implies the existence of any physical object in that world. The only contingent statements to be found in the foundation, he maintained, are those that are “about our own psychological states and the ways we are ‘appeared to’.” It is a view that, as Chisholm was well aware, tallies poorly with our ordinary practice of justifying statements. We (...) are typically happy to justify statements by ultimate appeal to what we have seen or heard; that is, by ultimate appeal to statements that logically imply that certain things in the world are as we take them to be. This essay examines how Chisholm sought to explain away this apparent disconfirmation of foundationalism by ordinary practice—in effect, how Chisholm responded to one of the chief criticisms of foundationalism launched by J. L. Austin. My suggestion will be that, when the dust clears, it is Austin who comes out ahead. (shrink)

Do we insult, offend or slight a speaker when we refuse her testimony? Do we compliment, commend or extol a speaker when we accept her testimony? I argue that the answer to both of these questions is “yes”, but only in some instances, since these respective insults and compliments track the reasons a hearer has for rejecting or accepting testimony. When disbelieving a speaker, a hearer may insult her because she judges the speaker to be either incompetent as a knower (...) or insincere as a teller. However, there are many instances where we reject testimony without making this negative evaluation of the speaker, and as such, without paying her an insult. Testimonial compliments are fewer in number, and are not constitutive of “everyday” testimonial exchanges, since, speakers who are competent as knowers and sincere as tellers are merely behaving correctly in accordance with the norms of testifying. Nevertheless, deferring to an authority on belief can be complimentary to that speaker if by doing so we judge her to have some mastery in a particular domain. Testimonial insults and compliments have important moral implications, particularly with regard to epistemic injustice and therapeutic trust. (shrink)

The Knower Paradox has had a brief but eventful history, and principles of epistemic closure (which say that a subject automatically knows any proposition she knows to be materially implied, or logically entailed, by a proposition she already knows) have been the subject of tremendous debate in epistemic logic and epistemology more generally, especially because the fate of standard arguments for and against skepticism seems to turn on the fate of closure. As far as I can tell, however, no one (...) working in either area has emphasized the result I emphasize in this paper: the Knower Paradox just falsifies even the most widely accepted general principles of epistemic closure. After establishing that result, I discuss five of its more important consequences. (shrink)

Any good theory of knowledge ascriptions should explain and predict our judgments about their felicity. I argue that any such explanation must take into account a distinction between three ways of using knowledge ascriptions: to suggest acceptance of the embedded proposition, to explain or predict a subject's behavior or attitudes, or to understand the relation of knowledge as such. The contextual effects on our judgments about felicity systematically differ between these three types of uses. Using such a distinction is, in (...) principle, open to both contextualist and pragmatic invariantist accounts of knowledge ascriptions. However, there are some implications pertaining to the use of the “method of cases” in the debate about knowledge ascriptions. (shrink)

Can knowledge be defined? We expound an argument of John Cook Wilson's that it cannot. Cook Wilson's argument connects knowing with having the power to inquire. We suggest that if he is right about that connection, then knowledge is, indeed, indefinable.

In ordinary circumstances in which we know there is a goldfinch on a branch in the garden, do we know that the thing on the branch isn’t stuffed? Austin’s methodology is perfectly compatible with holding both that we do and that we wouldn’t know it’s a goldfinch if we didn’t. Moreover, Austin’s methodology supports the claim that if we had no information whatsoever about whether it is stuffed, we wouldn’t know the thing on the branch is a goldfinch. Finally, Mark (...) Kaplan’s claim that P is part of your evidence if and only if you know that P leaves him with good reason to agree that in ordinary circumstances, you do know that the goldfinch isn’t stuffed. This result suggests a distinctive way of approaching arguments for external world skepticism with the structure of the so-called Argument from Ignorance. And it highlights just how much can be learned from approaching epistemological issues in an Austinian spirit. (shrink)
