This essay uses a puzzle about assertion and time to explore the pragmatics, semantics, and epistemology of future discourse. The puzzle concerns cases in which a subject is in a position to say, at an initial time t, that it will be that ϕ, but is not in a position to say, at a later time t′, that it is or was that ϕ, despite not losing or gaining any relevant evidence between t and t′. We consider a number of (...) approaches to the puzzle and defend the view that subjects in these cases lose knowledge simply by moving through time. (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)

Wittgenstein’s On Certainty is sometimes read as providing a response to the skeptical puzzle from closure, according to which our commitment to the trustworthiness of our evidence is not itself evidentially grounded. In this paper, I argue both that this standard reading of Wittgenstein is incorrect, and that a more accurate reading of Wittgenstein provides us with a more plausible solution to the Closure Puzzle.

This paper looks at an argument strategy for assessing the epistemic closure principle. This is the principle that says knowledge is closed under known entailment; or (roughly) if S knows p and S knows that p entails q, then S knows that q. The strategy in question looks to the individual conditions on knowledge to see if they are closed. According to one conjecture, if all the individual conditions are closed, then so too is knowledge. I give a deductive argument (...) for this conjecture. According to a second conjecture, if one (or more) condition is not closed, then neither is knowledge. I give an inductive argument for this conjecture. In sum, I defend the strategy by defending the claim that knowledge is closed if, and only if, all the conditions on knowledge are closed. After making my case, I look at what this means for the debate over whether knowledge is closed. (shrink)

We give a general description of a class of contrastive constructions, intended to capture what is common to contrastive knowledge, belief, hope, fear, understanding and other cases where one expresses a propositional attitude in terms of “rather than”. The crucial element is the agent's incapacity to distinguish some possibilities from others. Contrastivity requires a course-graining of the set of possible worlds. As a result, contrastivity will usually cut across logical consequence, so that an agent can have an attitude to p (...) rather than q but not to r rather than q , where r is a logical consequence of p . We relate these ideas to some general issues about thought, such as the question of whether all possibilities that can be distinguished in emotion can be distinguished in belief. (shrink)

One objection to the thesis that multilocation is possible claims that, when combined with a preference for parsimonious theories, it leads to the absurd result that we ought to believe the material universe is composed of just one simple particle. I argue that this objection fails.

Contextualism, in its standard form, is the view that the truth conditions of sentences of the form ‘S knows that P’ vary according to the context in which they are uttered. One possible objection to contextualism appeals to what Keith DeRose calls a warranted assertability maneuver (or WAM), according to which it is not our knowledge sentences themselves that have context-sensitive truth conditions, but what is pragmatically conveyed by the use of such sentences. Thus, proponents of WAMs argue, the context (...) sensitivity of knowledge attributions is not a semantic phenomenon but a pragmatic one. I examine a number of WAMs and show that each (i) is seriously flawed, or (ii) undercuts standard contextualism if we hold a minimalist conception of semantic content. I propose an alternative form of contextualism that accommodates minimalism and is immune to the second type of WAM, and show that this new form of contextualism shares the virtues of standard contextualism. (shrink)

In the paper, I contrast my contextualist account of Cartesian skepticism with Keith DeRose’s account. I agree with DeRose that when the Cartesian skeptic and her opponent meet in the same context, their claims are truth-value-less. But I agree with him on the basis of different conception of context sensitivity. According to DeRose, the content of context sensitive expressions in general, and of knowledge in particular, is personally indicated. Instead, for me, the content of context sensitive expressions in general, and (...) of knowledge in particular, is objectively determined by the goals of the conversation and the environment in which the conversation takes place.

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)

We often claim to know about what is good or bad, right or wrong. But how do we know such things? Both historically and today, answers to this question have most commonly been rationalist or sentimentalist in nature. Rationalists and sentimentalists clash over whether intellect or affect is the foundation of our evaluative knowledge. This paper is about the form that this dispute takes among those who agree that evaluative knowledge depends on perceptual-like evaluative experiences. Rationalist proponents of perceptualism invoke (...) intellectual experiences, while sentimentalist proponents invoke affective experiences. The goal of this paper is to offer a fresh strategy for adjudicating between intellectual and sentimental perceptualism. I argue that the perceptualist’s hand will be forced either in the direction of intellectual or sentimental perceptualism once she decides between two views about the modal status of our basic evaluative knowledge. I close with an argument that the more plausible of the two options is the one which fits best with sentimental perceptualism. The argument, then, is that perceptualists ought to be sentimentalists.

Experimental philosophers are often puzzled as to why many armchair philosophers question the philosophical significance of their research. Armchair philosophers, in contrast, are often puzzled as to why experimental philosophers think their work sheds any light on traditional philosophical problems. I argue there is truth on both sides.

Dretske’s theory of self-knowledge is interesting but peculiar and can seem implausible. He denies that we can know by introspection that we have thoughts, feelings, and experiences. But he allows that we can know by introspection what we think, feel, and experience. We consider two puzzles. The first puzzle, PUZZLE 1, is interpretive. Is there a way of understanding Dretske’s theory on which the knowledge affirmed by its positive side is different than the knowledge denied by its negative side? The (...) second puzzle, PUZZLE 2, is substantive. Each of the following theses has some prima facie plausibility: there is introspective knowledge of thoughts, knowledge requires evidence, and there are no experiences of thoughts. It is unclear, though, that these claims form a consistent set. These puzzles are not unrelated. Dretske’s theory of self-knowledge is a potential solution to PUZZLE 2 in that Dretske’s theory is meant to show how,, and can all be true. We provide a solution to PUZZLE 1 by appeal to Dretske’s early work in the philosophy of language on contrastive focus. We then distinguish between “Closure” and “Transmissibility”, and raise and answer a worry to the effect that Dretske’s theory of self-knowledge runs counter to Transmissibility. These results help to secure Dretske’s theory as a viable solution to PUZZLE 2. (shrink)

Discrimination is a central epistemic capacity but typically, theories of discrimination only use discrimination as a vehicle for analyzing knowledge. This paper aims at developing a self-contained theory of discrimination. Internalist theories of discrimination fail since there is no compelling correlation between discriminatory capacities and experiences. Moreover, statistical reliabilist theories are also flawed. Only a modal theory of discrimination is promising. Versions of sensitivity and adherence that take particular alternatives into account provide necessary and sufficient conditions on discrimination. Safety in (...) contrast is not sufficient for discrimination as there are cases of safety that are clearly instances of discrimination failure. The developed account of discrimination between objects will be extended to discrimination between kinds and between types. (shrink)

This is an anthology of ?fteen papers concerning various philosophical problems related to the topic of self-knowledge. All but one of the papers were previously unpublished, and all but two are descendants of presentations at a conference on self-knowledge held at the University of St Andrews in 1995.

John Martin Fischer's The Metaphysics of Free Will is devoted to two major projects. First, Fischer defends the thesis that determinism is incompatible with a person's control over alternatives to the actual future. Second, Fischer defends the striking thesis that such control is not necessary for moral responsibility. This review essay examines Fischer's arguments for each thesis. Fischer's defense of the incompatibilist thesis is the most innovative to date, and I argue that his formulation restructures the free will debate. To (...) defend his second thesis Fischer relies upon examples designed to show that an agent is responsible for an unavoidable action. I criticize Fischer's account of these examples, but I also maintain that my criticisms do not compromise his theory of responsibility. I raise several other difficulties for Fischer's theory of responsibility, and I close by offering some suggestions about how he might further defend it. (shrink)

The first step in responding to the challenge of external world skepticism is to get clear on the structure of the skeptic’s argument. The most prominent varieties of skeptical arguments either rely on closure principles or underdetermination principles. The relationship between these two sorts of arguments is contentious. Some argue that these arguments can independently motivate skepticism. Others argue that they are really equivalent. I argue that although these two arguments are distinct, their independence is not as obvious as some (...) have thought. The fact that these arguments are not equivalent is important because skeptical arguments that appeal to underdetermination principles cannot be refuted by simply denying closure. So, the strategy for responding to skepticism offered by Nozick/Dretske does not seem an adequate solution. (shrink)

I propose an account of desire that reconciles two apparently conflicting intuitions about practical agency. I do so by exploring a certain intuitive datum. The intuitive datum is that often when an agent desires P she will seem to immediately and conclusively know that there is a reason to bring P about. Desire-based theories of reasons seem uniquely placed to explain this intuitive datum. On this view, desires are the source of an agent’s practical reasons. A desire for P grounds (...) conclusive knowledge of a reason to bring P about because that desire makes it true that there is a reason to do so. However, this implies that a basic desire for P can never be in error about there being at least some reason to bring P about. We have the conflicting intuition that basic desires sometimes rationally count for nothing. The guise of the good explains this intuition about the fallibility of desires. On this view, a desire for P represents P as good in some respect. Desires and reasons are independent, so a desire might misrepresent one’s reasons. But this independence is usually taken to rule out that desires ever provide conclusive knowledge of reasons. Capturing the intuition about conclusive knowledge rules out capturing the intuition about fallibility, and vice versa. I propose an epistemological disjunctivist version of the guise of the good that reconciles fallibility with the possibility of conclusive knowledge. (shrink)

Suppose one has a visual experience as of having hands, and then reasons as follows: I have hands, If I have hands an external world exists; An external world exists. Suppose one’s visual experience gives one defeasible perceptual warrant, or justification, to believe – that is, one’s experience makes it epistemically appropriate to believe . And suppose one comes to believe on the basis of this visual experience. The conditional premise is knowable a priori. And can be established by modus (...) ponens inference. If one reasons thus, say one’s engaged in -reasoning. What, if anything, is wrong with -reasoning? I consider two prominent responses to this question – the dogmatists’ and Crispin Wright’s. Each finds fault in -reasoning, but on different grounds. I argue Wright’s response faces a problem which is standardly only taken to be faced by dogmatists. (shrink)

John Hawthorne has two forceful arguments in favour of:Single-Premise Closure Necessarily, if S knows p, competently deduces q from p, and thereby comes to believe q, while retaining knowledge of p throughout, then S knows q.Each of Hawthorne's arguments rests on an intuitively appealing principle which Hawthorne calls the Equivalence Principle. I show, however, that the opponents of SPC with whom he's engaging - namely Fred Dretske and Robert Nozick - have independent reason to reject this principle, and resultantly conclude (...) that Hawthorne's arguments in favour of SPC are not knock-down.

This article addresses the question of whether judges can take the internal point of view towardtheir legal system's rule of recognition for purely prudential reasons. It takes a fresh look at an underappreciated conceptual argument of Joseph Raz's that answers: no. In a nutshell, Raz argues that purely prudential reasons are reasons of the wrong kind for judges to accept their legal system's rule of recognition. And should Raz's argument succeed, an important necessary connection between law and morality would be (...) established. (shrink)

Take the following principle (or schema) as the focus of the ensuing discussion (“P” and “Q” are placeholders for propositions): 1 (Closure) If one knows P and competently deduces Q from P, thereby coming to believe Q, while retaining one's knowledge that P, one comes to know that Q. My strategy in outline: first, I want to set out Fred Dretske's classic challenge to (Closure) – a challenge which began in 1970–1971. Then I want to consider a specific, recent counter‐challenge (...) to Dretske's challenge to (Closure) mounted by John Hawthorne, and to defend Dretske's challenge from Hawthorne's counter‐challenge. Doing this is not to invalidate (Closure). In this regard my conclusions are modest: Dretske's challenge to (Closure) is – or, better: can be made – sophisticated and, so far, unmet. (shrink)

Stewart Cohen considers a case where his son wants a red table for his room. Cohen and his son go to the furniture store. Cohen’s son is concerned that the table his father is considering purchasing, which appears red, may in fact be white with red lights shining on it. Cohen responds with the following reasoning: The table looks red. The table is red. If the table is red, then it is not white with red lights shining on it. The (...) table is not white with red lights shining on it. If one reasons thus, say one’s engaged in -reasoning. Cohen finds such a response unsatisfactory. It is not a way of coming to know —it is too easy. And structurally similar reasoning delivers the falsity of sceptical hypotheses concerning the external world, testimony, other minds etc. So the unsatisfactoriness threatens to generalise. I consider Martin Davies ’s attempt to diagnose this unsatisfactoriness and find it incomplete. I then attempt to remedy the incompleteness in Davies ’s attempt. (shrink)

One common objection to Dretske’s Information Theoretic Account of Knowledge (ITAK) is that it violates closure. I show that it does not, and that extant arguments attempting to establish that it does rely instead on the KK thesis. That thesis does fail for ITAK. I show moreover that an interesting consequence of ITAK obeying the closure principle after all is that on this view if skepticism is false, we can have a great deal of empirical knowledge, but it is in (...) principle impossible to know that skepticism is false. In short, a proper understanding of how ITAK closes off the KK thesis shows that we can 1) take seriously the skeptic, we can 2) respond to her appropriately that we do have knowledge and we can 3) keep closure.

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)

If knowledge requires safety, then one might think that when the epistemic source of knowledge is testimony, that testimony must itself be safe. Otherwise, will not the lack of safety transfer from testimony to hearer, such that hearer will lack knowledge? Resisting this natural line of reasoning, Goldberg (2005; 2007) argues that testimonial knowledge through unsafe testimony is possible on the basis of two cases. Lackey (2008) and Pelling (2013) criticize Goldberg’s examples. But Pelling goes on to provide his own (...) example that attempts to show that Goldberg’s thesis is true: one can gain safe testimonial belief from unsafe testimony. If any of these counterexamples were correct, they would undermine the main reason to think that knowledge based on unsafe testimony is impossible. My aim in this paper is to critically assess these arguments, and to consider the possibility of knowledge through unsafe testimony. Drawing a general moral from the analysis of these cases, I shall contend that it is impossible to acquire safe belief solely on the basis of unsafe testimony. If so, then testimonial knowledge based solely on unsafe testimony is impossible. (shrink)

The principle of Counter-Closure embodies the widespread view that when a proposition is believed solely as the conclusion of single-premise deduction, it can be known only if the premise is also known. I raise a problem for the compatibility of Jason Stanley's Interest-Relative Invariantism (IRI) with Counter-Closure. I explore the landscape of options that might help Stanley resolve this tension and argue that a trilemma confronts Stanley: he must either (i) renounce a key intuition that lies at the foundation of (...) his view; or (ii) admit into his epistemology an IRI-specific novel brand of Gettier case; or (iii) abandon Counter-Closure. (shrink)

I argue that DeRose's attributor contextualism cannot straightforwardly preserve the widespread view that, when a subject believes q solely on the basis of competent deduction from p, knowledge of q requires knowledge of p. I present a novel challenge to the compatibility of this widespread view with DeRose's contextualism, then argue that the tension can be resolved in only one of two ways: if DeRose rejects the widespread view or if DeRose accepts the existence of a range of contextualism-specific Gettier-style (...) cases.

Neste ensaio, pretendemos (1) sugerir algumas vantagens da apresentação do ceticismo na forma de um argumento cético geral, (2) discutir o princípio de fechamento utilizado neste argumento, (3) mostrar que o confiablismo externalista é incapaz de explicar as implicações deste argumento geral e (4) defender uma posição internalista cancelabilista como a mais adequadamente munida de ferramentas para avaliação dos desafios céticos.

Suppose Ted is in an ordinary house in good viewing conditions and believes red, his table is red, entirely because he sees his table and its color; he also believes not-white, it is false that his table is white and illuminated by a red light, because not-white is entailed by red. The following three claims about this table case clash, but each seems plausible: 1. Ted’s epistemic position is strong enough for him to know red. 2. Ted cannot know not-white (...) on the basis of red. 3. The epistemic closure principle, suitably restricted, is true. Stewart Cohen has called this three-way clash of intuitions the problem of easy knowledge. If we wish to resolve the clash without accepting skepticism, we seem to have two options. According to the hard argument, the best response is to reject 3. The easy argument rejects 2. But there may be a third alternative, the reverse argument, which rejects 1 without ceding a substantial amount of ground to the skeptic. In this essay I criticize recent versions of the reverse argument and the hard argument, thereby lending support to the easy argument. (shrink)

In early essays and in more recent work, Fred Dretske argues against the closure of perception, perceptual knowledge, and knowledge itself. In this essay I review his case and suggest that, in a useful sense, perception is closed, and that, while perceptual knowledge is not closed under entailment, perceptually based knowledge is closed, and so is knowledge itself. On my approach, which emphasizes the safe indication account of knowledge, we can both perceive, and know, that sceptical scenarios (such as being (...) a brain in a vat) do not hold. (shrink)

Recently, Jonathan Schaffer has defended a contrastivist analysis of knowledge. By appealing to his account, he has attempted to steer a path between skepticism and Moore-style antiskepticism: much like sensitivity theorists and contextualists, he offers significant concessions to, but ultimately rejects, both. In this essay I suggest that in fact Schaffer ends up succumbing to skepticism.

In this paper, I examine Crispin Wright’s most recent attempt to introduce a diagnostic tool for predicting failures of warrant transmission, the so-called ‘Revised Template’. I show that the Revised Template does not, in fact, generate the predictions about warrant transmission failure that Wright thinks it does. I argue that the failure lies, in large part, with the definition of the technical notion ‘presupposition’ which the Revised Template deploys. Through a consideration of Wright’s own ‘general motivation’ for the Revised Template, (...) I extract an alternative characterization of ‘presupposition’ and use this to fuel a diagnostic tool for predicting failures of warrant transmission which, I believe, is both more faithful to Wright’s own general motivating remarks and more successful in predicting failures of warrant transmission than the Revised Template.

May argues that moral skepticism is less plausible than perceptual skepticism if it’s formulated using epistemic closure. In this paper, I argue we should be skeptical of the implausibility thesis. Moral skepticism can be formulated using closure if we combine moral nihilism with a properly formulated evolutionary scenario. Further, I argue that pace May, the phenomenon of ‘imaginative resistance’ isn’t an issue for the moral skeptic; she has an evolutionary explanation of the phenomenon. Thus, we should be skeptical of the (...) implausibility thesis. (shrink)

There is a controversy, within social epistemology, over how to handle disagreement among epistemic peers. Call this the problem of peer disagreement. There is a solution, i.e. the equal-weight view, which says that disagreement among epistemic peers is a reason for each peer to lower the credence they place in their respective positions. However, this solution is susceptible to a serious challenge. Call it the merely modal peers challenge. Throughout parts of modal space, which resemble the actual world almost completely, (...) there are hordes of epistemic peers, who disagree with almost any arbitrarily chosen belief had by residents of the actual world. Further, the mere modality of these peers is not itself an epistemic difference-maker. Thus, on the equal-weight view, we should significantly lower the credence we place in most of our beliefs. Surely, this is seriously mistaken. Thus, there are serious considerations that cut against the equal-weight view. (shrink)

Radical experimentalists argue that we should give up using intuitions as evidence in philosophy. In this paper, I first argue that the studies presented by the radical experimentalists in fact suggest that some intuitions are reliable. I next consider and reject a different way of handling the radical experimentalists' challenge, what I call the Argument from Robust Intuitions. I then propose a way of understanding why some intuitions can be unreliable and how intuitions can conflict, and I argue that on (...) this understanding, both moderate experimentalism and the standard philosophical practice of using intuitions as evidence can help resolve these conflicts.

All standard epistemic logics legitimate something akin to the principle of closure, according to which knowledge is closed under competent deductive inference. And yet the principle of closure, particularly in its multiple premise guise, has a somewhat ambivalent status within epistemology. One might think that serious concerns about closure point us away from epistemic logic altogether—away from the very idea that the knowledge relation could be fruitfully treated as a kind of modal operator. This, however, need not be so. The (...) abandonment of closure may yet leave in place plenty of formal structure amenable to systematic logical treatment. In this paper we describe a family of weak epistemic logics in which closure fails, and describe two alternative semantic frameworks in which these logics can be modelled. One of these—which we term plurality semantics—is relatively unfamiliar. We explore under what conditions plurality frames validate certain much-discussed principles of epistemic logic. It turns out that plurality frames can be interpreted in a very natural way in light of one motivation for rejecting closure, adding to the significance of our technical work. The second framework that we employ—neighbourhood semantics—is much better known. But we show that it too can be interpreted in a way that comports with a certain motivation for rejecting closure.

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)

Clanak se bavi pojmom epistemicke srece i njegovim znacajem za dva vazna epistemoloska problema, analizu znanja i problem skepticizma. Okosnicu rasprava cini poznata sokratovska intuicija, oko koje se filozofi gotovo bezrezervno slazu, da je znanje nespojivo sa prekomernim udelom srecnog sticaja okolnosti u otkricu istine. U svetlu Pricardovog modalnog tumacenja pojma epistemicke srece i razlikovanje veridicke i refleksivne epistemicke srece, razmatraju se prednosti i mane dve osnovne suprotstavljene koncepcije znanja, internalizma i eksternalizma.

Iako ne otklanja refleksivnu epistemicku srecu i ne resava problem skepticizma formulisan na meta-nivou, eksternalizam ukupno uzev predstavlja prihvatljiviju koncepciju ljudskog znanja pogotovu zato sto moze da prihvati cinjenicu da internalisticko opravdanje igra znacajnu ulogu u nasem saznanju.

The notion of relevance plays a role in many accounts of knowledge and knowledge ascription. Although use of the notion is well-motivated, theorists struggle to codify relevance. A reasonable person standard of relevance addresses this codification problem, and provides an objective and flexible standard of relevance; however, treating relevance as reasonableness seems to allow practical factors to determine whether one has knowledge or not—so-called “pragmatic encroachment.” I argue that a fuller understanding of reasonableness and of the role of practical factors (...) in the acquisition of knowledge lets us avoid pragmatic encroachment.
