Consider the argument: Circus-1 Men in clown suits are handing out tickets. So, probably: Circus-2 There’s a circus in town. So: Circus-3 There’s an entertainment venue in town. Presumably you’d be able to warrantedly believe Circus-2 on the basis of Circus-1. And we can suppose you’re reasonably certain that wherever there are circuses, there are entertainment venues. So you’d seem to be in a position to reasonably go on to infer Circus-3.

Is the nature of testimonial warrant epistemically internalist or externalist? I will argue that the question should be answered ‘yes!’ The disjunction is not exclusive. Rather, a testimonial belief may possess epistemically internalist warrant—justification—as well as epistemically externalist warrant—entitlement. I use the label ‘pluralism’ to denote the view that there are both internalist and externalist species of genuinely epistemic warrant and argue for pluralism in the epistemology of testimony.

Two different versions of epistemological disjunctivism have recently been upheld in the literature: a traditional, Justified True Belief Epistemological Disjunctivism (JTBED) and a Knowledge First Epistemological Disjunctivism (KFED). JTBED holds that factive reasons of the form “S sees that p” provide the rational support in virtue of which one has perceptual knowledge, while KFED holds that factive reasons of the form “S sees that p” just are ways of knowing that p which additionally provide justification for believing that p. We (...) argue that both accounts remain ultimately unsatisfactory. JTBED faces two formidable problems: first, it cannot account for animal knowledge, and, second, it does not offer a satisfactory account of how we access factive reasons. Although KFED can solve these two problems, it has some problems of its own. While intuitively knowledge is logically stronger than justified belief, on KFED it turns out to be weaker: knowledge does not entail justified belief, but justified belief does entail knowledge. Nevertheless, disjunctivists are right on at least a couple of points: we standardly justify our perceptual beliefs by appealing to factive reasons such as seeing that p and so factive reasons ought to play some role in our theory of justification. In addition, KFED’s account of our access to factive reasons also is spot on. Rather than going disjunctivist, these insights can be suitably incorporated into a Knowledge First Virtue Epistemology (KFVE). (shrink)

This book takes purism about knowledge as the default position and defends it from the challenges of pragmatic encroachment. The book is divided into two parts, a negative and a positive one. The negative part critically examines existing purist strategies in response to pragmatic encroachment. The positive part provides a new theory of how practical factors can systematically influence our confidence and explores some implications of such influence. In particular, it provides a new purist explanation of the data commonly used (...) to motivate pragmatic encroachment on knowledge. Moreover, it develops a new variety of pragmatic encroachment, not on knowledge but on credence. Thus, my aim in this book is not to provide a full-fledged defence of all kinds of purism. Rather, I argue for purism about knowledge but pragmatic encroachment about credence. This book is a revised version of my PhD dissertation “Belief, Knowledge and Action”. In this revision, I have made some substantive changes, introduced some stylistic changes and added discussions of new relevant literature. (shrink)

The case of very young children is a test case for the plausibility of reductionism about testimonial warrant. Reductionism requires reductive reasons, reductively justified and actively deployed for testimonial justification. Though nascent language-users enjoy warranted testimony based beliefs, they do not meet these three reductionist demands. This paper clearly formulates reductionism and the infant/child objection. Two rejoinders are discussed: an influential conceptual argument from Jennifer Lackey’s paper “Testimony and the Infant/Child Objection” and the growing empirical evidence from developmental psychology on (...) selective trust in children. Neither Lackey’s argument nor the empirical evidence vindicate reductionism. (shrink)

This paper is an essay in counterfactual epistemology. What if experience have high-level contents, to the effect that something is a lemon or that someone is sad? I survey the consequences for epistemology of such a scenario, and conclude that many of the striking consequences could be reached even if our experiences don't have high-level contents.

On two standard views of vagueness, vagueness as to whether Harry is bald entails that nobody knows whether Harry is bald—either because vagueness is a type of missing truth, and so there is nothing to know, or because vagueness is a type of ignorance, and so even though there is a truth of the matter, nobody can know what that truth is. Vagueness as to whether Harry is bald does entail that nobody clearly knows that Harry is bald and that (...) nobody clearly knows that Harry is not bald. But it does not entail that nobody knows that Harry is bald or that nobody knows that Harry is not bald. Hence, the two standard views of vagueness are mistaken. (shrink)

I lay out the framework for my theory of sensory imagination in “Imagining as a guide to possibility.” Sensory imagining involves mental imagery , and crucially, in describing the content of imagining, I distinguish between qualitative content and assigned content. Qualitative content derives from the mental image itself; for visual imaginings, it is what is “pictured.” For example, visually imagine the Philadelphia Eagles defeating the Pittsburgh Steelers to win their first Super Bowl. You picture the greenness of the field and (...) the football’s brown oblong shape. Some of what you imagine isn’t explicitly pictured, however. That it is Sunday, that it is the Super Bowl: these facts are assigned. (shrink)

One central fact about hallucinations is that they may be subjectively indistinguishable from perceptions. Indeed, it has been argued that the hallucinatory experiences concerned cannot— and need not—be characterized in any more positive general terms. This epistemic conception of hallucinations has been advocated as the best choice for proponents of experiential (or “naive realist”) disjunctivism—the view that perceptions and hallucinations differ essentially in their introspectible subjective characters. In this chapter, I aim to formulate and defend an intentional alternative to experiential (...) disjunctivism called experiential intentionalism. This view not only enjoys some advantages over its rival but is also compatible with the epistemic conception of hallucinations, as well as with the disjunctivist view that perceptions and hallucinations differ essentially in their third-personal structures (e.g., their causal, informational, or reason-providing links to reality). It also maintains that there are actually two aspects to the subjective indistinguishability of mental episodes: (i) we cannot distinguish their first-personal characters in introspective awareness; and (ii) we cannot distinguish their third-personal structures in experiential awareness—that is, in how they are given to consciousness. While experiential disjunctivism makes the mistake of ignoring (ii) and reducing subjective indiscriminability to (i), experiential intentionalism correctly identifies (ii) as the primary source of the subjective indistinguishability of perception-like hallucinations. Accordingly, the intentional error involved in such hallucinations is due to the fact that we consciously experience them as possessing a relational structure. (shrink)

I argue that its appearing to you that P does not provide justification for believing that P unless you have independent justification for the denial of skeptical alternatives – hypotheses incompatible with P but such that if they were true, it would still appear to you that P. Thus I challenge the popular view of ‘dogmatism,’ according to which for some contents P, you need only lack reason to suspect that skeptical alternatives are true, in order for an experience as (...) of P to justify belief that P. I pursue three lines of objection to dogmatism, having to do with probabilistic reasoning, considerations of future or hypothetically available justification, and epistemic circularity. I briefly sketch a fall-back position which avoids the problems raised. (shrink)

In previous work, I have suggested a doxastic account of perceptual experience according to which experiences form a kind of belief: Beliefs with what I have called “phenomenal” or “looks-content”. I have argued that this account can not only accommodate the intuitive reason providing role of experience, but also its justificatory role. I have also argued that, in general, construing experience and perceptual beliefs, i.e. the beliefs most directly based on experience, as having different contents best accounts for the defeasibility (...) of experiential reasons. In this paper, I shall have a closer look at the evidential or inferential relation between looks-propositions and the contents of perceptual beliefs and argue for a form of what I shall call “Pollockianism” about experiential reasons: such reasons are good unless defeated. Questions to be investigated include: Does the resulting picture of perceptual justification contain an externalist element? Is it compatible with Bayesianism? And how does it do with respect to problems that have been raised for other forms of Pollockianism such as dogmatism or phenomenal conservatism? (shrink)

In this paper I try to defend McDowell’s empiricism from a certain objection made by Davidson, Stroud and Glüer. The objection states that experiences cannot be reasons because they are—as McDowell conceives them—inert. I argue that, even though there is something correct in the objection, that is not sufficient for rejecting the epistemological character that McDowell attributes to experiences. My strategy consists basically in showing that experiences involve a constitutive attitude of acceptance of their contents.

Perceptual experiences justify beliefs. A perceptual experience of a dog justifies the belief that there is a dog present. But there is much evidence that perceptual states can occur without being conscious, as in experiments involving masked priming. Do unconscious perceptual states provide justification as well? The answer depends on one’s theory of justification. While most varieties of externalism seem compatible with unconscious perceptual justification, several theories have recently afforded to consciousness a special role in perceptual justification. We argue that (...) such views face a dilemma: either consciousness should be understood in functionalist terms, in which case our best current theories of consciousness do not seem to imbue consciousness with any special epistemic features, or it should not, in which case it is mysterious why only conscious states are justificatory. We conclude that unconscious perceptual justification is quite plausible. (shrink)

Nearly everyone agrees that perception gives us justification and knowledge, and a great number of epistemologists endorse a particular two-part view about how this happens. The view is that perceptual beliefs get their justification from perceptual experiences, and that they do so by being based on them. Despite the ubiquity of these two views, I think that neither has very much going for it; on the contrary, there’s good reason not to believe either one of them.

I attempt to set the stage for a constructive analysis of the nature and function of tensed belief as a distinct psychological type. After introducing tensed beliefs, I describe the philosophical issues that implicate them, including Prior’s “ thank goodness it’s over ” argument against the B-theory of time. I proceed to flesh out, and then argue against, two traditional treatments of tensed belief from the philosophy of time: the A-theoretic view, which starts from present facts or properties, and Hugh (...) Mellor's B-theoretic reply, which starts from the tenseless properties of tensed belief tokens. The explanatory failure of the former shows that, pace Prior, the existence of tensed attitudes does not favor the A-theory, while the failure of both shows that there are still explanatory gaps that we need to fill. I conclude by offering a working definition of tensed belief and the ideal methodology for filling out these explanatory gaps in future study. (shrink)

Our awareness of the boundedness of the spatial sensory field—a paradigmatic structural feature of visual experience—possesses a distinctive epistemic role. Properly understood, this result undermines a widely assumed picture of how visual experience permits us to learn about the world. This paper defends an alternative picture in which visual experience provides at least two kinds of non-inferential justification for beliefs about the external world. Accommodating this justification in turn requires recognising a new way for visual experience to encode information about (...) the world. Reflection upon the epistemic contribution of sensory experience's structural features thus forces us to revise our understanding of how perception, cognition, and the world fit together. (shrink)

In this paper, I argue against recent versions of justification norms of action and practical deliberation . I demonstrate that these norms yield unacceptable results in deception cases. However, a further modification of justification norms in the light of these results appears to be ad hoc. Hence, I claim, we should reject justification norms of action and practical deliberation.

Though the divide between reason-based and causal-explanatory approaches in psychiatry and psychopathology is old and deeply rooted, current trends involving multi-factorial explanatory models and evidence-based approaches to interpersonal psychotherapy, show that it has already been implicitly bridged. These trends require a philosophical reconsideration of how reasons can be causes. This paper contributes to that trajectory by arguing that Donald Davidson’s classic paradigm of 1963 is still a valid option.

I am going to argue for a robust realism about magnitudes, as irreducible elements in our ontology. This realistic attitude, I will argue, gives a better metaphysics than the alternatives. It suggests some new options in the philosophy of science. It also provides the materials for a better account of the mind’s relation to the world, in particular its perceptual relations.

This article develops and defends a full account of the nature and normativity of resistance to evidence, according to which resistance to evidence is an instance of input-level epistemic malfunctioning. At the core of this epistemic normative picture lies the notion of knowledge indicators, as evidential probability increasing facts that one is in a position to know; resistance to evidence is construed as a failure to uptake knowledge indicators.

De re or singular thoughts are, intuitively, those essentially or constitutively about a particular object or objects; any thought about different objects would be a different thought. How should a philosophical articulation or thematization of their nature look like? In spite of extended discussion of the issue since it was brought to the attention of the philosophical community in the late fifties by Quine (1956), we are far from having a plausible response. This is glaringly revealed by the contrasting recent (...) takes on the issue by writers such as Soames (2005) – who adopts the view by Donnellan (1979) to be outlined presently – and Jeshion (2001), otherwise sharing a similar direct-reference approach to the prototypical expression of those contents. Discussing the matter in connection with the status of the Kripkean category of the contingent a priori in the just mentioned article, Donnellan (1979) argued that what can be properly classified as knowable a priori about utterances like those involving ‘one meter’ or ‘Neptune’ famously proposed by Kripke (1980) cannot be the very same singular content that is contingent; he distinguished to that end between knowing a true proposition expressed by an utterance, and knowing that an utterance expresses a true proposition. (Thus, for instance, if, while listening to an utterance in a language that I do not know, I am told by a reliable person who knows the language and whom I trust that the utterance is true, I come thereby to know that the sentence expresses a truth, without knowing the truth that it expresses.) Evans (1979) replied that, for a very specific sort of cases involving “descriptive names”, a related proto-two-dimensionalist account should be preferred, on which it is not the singular contingent content, but rather a general descriptive one which is knowable a priori. In a series of papers, Robin Jeshion (2000, 2001) has recently attacked Donnellan's proposal, arguing in favour of the most straightforward interpretation of Kripke's claim: in the relevant cases, the very same singular content can be both contingent and knowable a priori. In this paper, I will appeal to a generalized version of two-dimensional semantics to advance an account of the Kripkean cases along the lines of Evans's, and I will argue that Jeshion's compelling arguments against Donnellan's view do not apply to this version.

Philosophy and Phenomenological Research, EarlyView.

Fodor advocates a view of cognitive processes as computations defined over the language of thought (or Mentalese). Even among those who endorse Mentalese, considerable controversy surrounds its representational format. What semantically relevant structure should scientific psychology attribute to Mentalese symbols? Researchers commonly emphasize logical structure, akin to that displayed by predicate calculus sentences. To counteract this tendency, I discuss computational models of navigation drawn from probabilistic robotics. These models involve computations defined over cognitive maps, which have geometric rather than logical (...) structure. They thereby demonstrate the possibility of rational cognitive processes in an exclusively non-logical representational medium. Furthermore, they offer much promise for the empirical study of animal navigation. (shrink)

Recent philosophical discussions of self-knowledge have focused on basic cases: our knowledge of our own thoughts, beliefs, sensations, experiences, preferences, and intentions. Empiricists argue that we acquire this sort of self-knowledge through inner perception; rationalists assign basic self-knowledge an even more secure source in reason and conceptual understanding. I try to split the difference. Although our knowledge of our own beliefs and thoughts is conceptually insured, our knowledge of our experiences is relevantly like our perceptual knowledge of the external world.

Perceptual beliefs that categorize objects can be justified by demonstrating basic properties (eg shapes) of the objects. In these justifications, perceptual justifiers have different contents to the beliefs they justify. I argue that the justifications are not inferential. Subjects are unlikely to have bodies of beliefs adequate to inferentially justify the beliefs they actually form on the strength of their object recognition abilities, especially when recognition depends on stimulus-dependent retrieval of visual memories. Instead, I argue, the justifications exploit a partial (...) awareness that subjects have of states and processes involved in object recognition. As such, they show that subjects have a degree of internal access to the principles of externalistic perceptual warrant, and to the features of perceptual states that give them justificatory force on externalistic accounts. The justifications themselves are evidential, but in order for them to have any justificatory force, they have to be placed in an externalistic framework for perceptual justification. I conclude that this form of justification shows that subjects have a degree of insight into why their perceptual experiences justify their beliefs. (shrink)

According to Burge, it is not possible to commit brute errors in the process of critical reasoning. This thesis lies at the heart of Burge’s influential theory of self-knowledge. By appealing to a version of the slow-switching argument, this paper contends that Burge’s view is not compatible with his commitment to externalism about mental content. In particular, it is argued that accepting externalism opens up the possibility of brute errors in the process of critical reasoning.

In this article, I reply to the comments that Richard Holton, Peter Railton, and James Lenman have made on my 2007 book "The Nature of Normativity".

¿Hay requisitos epistemológicos para la posesión de conceptos? Aunque nuestra intuición apunta claramente a una relación muy estrecha entre condiciones de posesión de conceptos y ciertos tipos de conocimiento, posiciones naturalistas en filosofía —como la defendida por Jerry Fodor— traen consigo una visión según la cual los conceptos que un sujeto posee son independientes metafísica y conceptualmente de las capacidades epistémicas de dicho sujeto. En este artículo argumentaré que, tal y como el análisis del dogmatismo de Pryor puede mostrar, las (...) teorías de la justificación epistémica proporcionan, desde un punto de vista general, apoyo independiente a la idea intuitiva de requisitos epistemológicos para la posesión de conceptos. Por este motivo, las aproximaciones naturalistas a los conceptos harían bien en evitar condiciones de posesión que carezcan de compromisos epistemológicos. (shrink)

This article is concerned with the question of the nature of the epistemic liaison between experience and belief. The problem, often known as the problem of nondoxastic justification, is to see how a causal transition between experience and belief could assume a normative dimension, that is, how perceptual experience serves to justify beliefs about the world. Currently a number of theories have been proposed to resolve this problem. The article considers a particular solution offered by Tyler Burge which, among other (...) things, introduces a new type of positive epistemic status or warrant, namely, entitlement. It contends that Burge's notion of entitlement cannot be of any help in resolving the problem of nondoxastic justification. Burge's account is compared and contrasted with other, similar, approaches to the problem of nondoxastic justification. (shrink)

In this paper I argue that the representational theory of perception, on which the world is represented as being a certain way in perceptual experience, cannot explain how there can be a genuinely epistemic connection between experience and belief. I try to show that we are positively required to deny that perceptual consciousness is contentful if we want to make its fitness for epistemic duties intelligible. (So versions of the representational theory on which experience has a merely causal purchase on (...) belief are not considered.) But my aim is not just negative. I try to defeat representationalism in such a way as to motivate a robustly presentational theory of perception. According to such a theory, perceptions are relations not between a subject and a content but between a subject and an ordinary object (such that if the relation holds at t, an appropriate subject and object must exist at t, and the object must be presented to the subject). I end by sketching an account of perceptual experience that is meant to show that, contrary to a very popular misconception, there is a way to conceive perceptual consciousness as relational and presentational (not intentional and representational) that does not succumb to the celebrated ?myth of the Given?

According to a view I’ll call Epistemic Normativism, knowledge is normative in the same sense in which paradigmatically normative properties like justification are normative. This paper argues against EN in two stages and defends a positive non-normativist alternative. After clarifying the target in §1, I consider in §2 some arguments for EN from the premise that knowledge entails justification. I first raise some worries about inferring constitution from entailment. I then rehearse the reasons why some epistemologists reject the Entailment Thesis (...) and argue that a non-normativist picture provides the best explanation of all the intuitions surrounding this thesis, favorable and unfavorable. On this picture, human knowledge is a structured non-normative complex that has as one of its parts a justification-making property, analogous in role to good-making properties like pleasurableness. After giving three arguments against EN in §3 and answering an objection in §4, I turn in §5 to further develop the positive view sketched in §2. In §6, I take stock and conclude. (shrink)

I undermine the argument that ‘high’ epistemic standards are false because children and other cognitively unsophisticated subjects possess justification while lacking certain logical and epistemic concepts. I argue, instead, that the standards we often use to attribute logical and epistemic concepts to ordinary, cognitively sophisticated adults can easily be seen to cover many unsophisticated subjects; therefore, the alleged lack of certain concepts is no basis for rejecting ‘high’ epistemic standards. Whether or not such standards are correct has to be argued (...) on other grounds. (shrink)

In this paper, I argue that perception justifies belief about the external world in virtue of its phenomenal character together with its relations to the external world. But I argue that perceptual relations to the external world impact on the justifying role of perception only by virtue of their impact on its representational content. Epistemic level-bridging principles provide a principled rationale for avoiding more radically externalist theories of perceptual justification.

Tyler Burge notably offers a truth‐first account of perceptual entitlement in terms of a priori necessary representational functions and norms: on his account, epistemic normativity turns on natural norms, which turn on representational functions. This paper has two aims: first, it criticises Tyler Burge's truth‐first a priori derivation on functionalist and value‐theoretic grounds. Second, it develops a novel, knowledge‐first a priori derivation of perceptual entitlement. According to the view developed here, it is a priori that we are entitled to believe (...) the deliverances of our perceptual belief formation system, in virtue of the latter's constitutive function of generating knowledge.

This paper examines how new evil demon problems could arise for our access to the internal world of our own minds. I start by arguing that the internalist/externalist debate in epistemology has been widely misconstrued---we need to reconfigure the debate in order to see how it can arise about our access to the internal world. I then argue for the coherence of scenarios of radical deception about our own minds, and I use them to defend a properly formulated internalist view (...) about our access to our minds. The overarching lesson is that general epistemology and the specialized epistemology of introspection need to talk---each has much to learn from each other. (shrink)

Psychologists and neuroscientists have delivered a lot of bad news about the inner workings of our minds, raising challenging questions about the extent to which we are rational in important domains of our judgments. I will focus on a central case of an unsettling effect on our perception, and primarily aim to establish that there actually is no impact from it on the rationality of our perceptual beliefs. To reach my goal, I will start with a rough review of different (...) ways bad news about our minds might negatively affect our rationality. I’ll then propose a test for when negative consequences would follow from the truth of some bad news about our minds, and I will argue that the test is not passed in a paradigmatic case of influence of bias on perception. I will then close by looking at potential wider implications of the psychological bad news for debates about internalism vs. externalism in epistemology. (shrink)

This paper evaluates the prospects of harnessing “anti-individualism” about the contents of perceptual states to give an account of the epistemology of perception, making special reference to Tyler Burge’s ( 2003 ) paper, “Perceptual Entitlement”. I start by clarifying what kind of warrant is provided by perceptual experience, and I go on to survey different ways one might explain the warrant provided by perceptual experience in terms of anti-individualist views about the individuation of perceptual states. I close by motivating accounts (...) which instead give a more prominent role to consciousness. (shrink)

It is often taken for granted that our desires can contribute to what it is rational for us to do. This paper examines an account of desire—the ‘guise of the good’— that promises an explanation of this datum. I argue that extant guise-of-the-good accounts fail to provide an adequate explanation of how a class of desires—basic desires—contributes to practical rationality. I develop an alternative guise-of-the-good account on which basic desires attune us to our reasons for action in virtue of their (...) biological function. This account emphasises the role of desire as part of our competence to recognise and respond to normative reasons. (shrink)

This paper evaluates the claim that some desires provide reasons in virtue of their connection with conscious affective experiences like feelings of attraction or aversion. I clarify the nature of affective desires and several distinct ways in which affective desires might provide reasons. Against accounts proposed by Ruth Chang, Declan Smithies and Jeremy Weiss, I motivate doubts that it is the phenomenology of affective experiences that explains their normative or rational significance. I outline an alternative approach that centralises the function (...) of such experiences. (shrink)

The paper starts by describing and clarifying what Williamson calls the consequence fallacy. I show two ways in which one might commit the fallacy. The first, which is rather trivial, involves overlooking background information; the second way, which is the more philosophically interesting, involves overlooking prior probabilities. In the following section, I describe a powerful form of sceptical argument, which is the main topic of the paper, elaborating on previous work by Huemer. The argument attempts to show the impossibility of (...) defeasible justification, justification based on evidence which does not entail the (allegedly) justified proposition or belief. I then discuss the relation between the consequence fallacy, or some similar enough reasoning, and that form of argument. I argue that one can resist that form of sceptical argument if one gives up the idea that a belief cannot be justified unless it is supported by the totality of the evidence available to the subject—a principle entailed by many prominent epistemological views, most clearly by epistemological evidentialism. The justification, in the relevant cases, should instead derive solely from the prior probability of the proposition. A justification of this sort, that does not rely on evidence, would amount to a form of entitlement, in (something like) Crispin Wright’s sense. I conclude with some discussion of how to understand prior probabilities, and how to develop the notion of entitlement in an externalist epistemological framework. (shrink)

Perceptual constancies have been studied by psychologists for decades, but in recent years, they have also become a major topic in the philosophy of mind. One reason for this surge of interest is Tyler Burge’s (2010) influential claim that constancy mechanisms mark the difference between perception and mere sensitivity, and thereby also the difference between organisms with genuine representational capacities and ‘mindless’ beings. Burge’s claim has been the subject of intense debate. It is becoming increasingly clear, however, that we cannot (...) hope to settle this debate (as well as related debates in the philosophy of mind) without a clear and substantive theoretical account of what perceptual constancies are. In the first part of this paper, I argue that the standard definitions in the literature fall short of providing such an account. Still, as I aim to show in the second part of the paper, by taking a closer look at some of the paradigm examples, it is possible to construct a plausible general account of perceptual constancies that is both clear and substantive, and that can serve as a firm foundation for settling debates like the dispute about Burge’s ‘constancy mechanism criterion’ for perception.

What is the metaphysical nature of perceptual experience? What evidence does experience provide us with? These questions are typically addressed in isolation. In order to make progress in answering both questions, perceptual experience needs to be studied in an integrated manner. I develop a unified account of the phenomenological and epistemological role of perceptual experience, by arguing that sensory states provide perceptual evidence due to their metaphysical structure. More specifically, I argue that sensory states are individuated by the perceptual capacities (...) employed and that there is an asymmetric dependence between their employment in perception and their employment in hallucination and illusion. Due to this asymmetric dependence, sensory states provide us with evidence. (shrink)

Perceptions guide our actions and provide us with evidence of the world around us. Illusions and hallucinations can mislead us: they may prompt as to act in ways that do not mesh with the world around us and they may lead us to form false beliefs about that world. The capacity view provides an account of evidence that does justice to these two facts. It shows in virtue of what illusions and hallucinations mislead us and prompt us to act. Moreover, (...) it shows in virtue of what we are in a better epistemic position when we perceive than when we hallucination. In this paper, I develop the capacity view, that is, the view that perceptual experience has epistemic force in virtue of the epistemic and metaphysical primacy of the perceptual capacities employed in perception. By grounding the epistemic force of experience in facts about the metaphysical structure of experience, the capacity view is not only an externalist view, but moreover a naturalistic view of the epistemology of perceptual experience. So it is an externalist and naturalistic alternative to reliabilism. I discuss the repercussions of this view for the justification of beliefs and the epistemic transparency of mental states, as well as, familiar problem cases. (shrink)
