Philosophers of perception have a notoriously difficult time trying to account for hallucinatory experiences. One surprisingly quite popular move, and one that cross-cuts the representationalism/relationalism divide, is to say that hallucinations involve an awareness of uninstantiated properties. In this paper, I provide a new argument against this view. Not only are its proponents forced to classify many hallucinations as veridical, such experiences turn out to be necessarily veridical. In addition, I show that representationalists who endorse the uninstantiated property view must (...) reject the common fundamental kind claim and adopt disjunctivism, and naïve realists/relationalists must radically modify their disjunctivism: The distinction between ‘veridical’ and ‘hallucinatory’ will no longer track a metaphysical distinction between the relevant experiences.

Conceptualism is the thesis that, for any perceptual experience E, (i) E has a Fregean proposition as its content and (ii) a subject of E must possess a concept for each item represented by E. We advance a framework within which conceptualism may be defended against its most serious objections (e.g., Richard Heck's argument from nonveridical experience). The framework is of independent interest for the philosophy of mind and epistemology given its implications for debates regarding transparency, relationalism and representationalism, demonstrative (...) thought, phenomenal character, and the speckled hen objection to modest foundationalism.

Many people have recently argued that we need to distinguish between experiences and seemings and that this has consequences for views about how perception provides evidence. In this article I spell out my take on these issues by doing three things. First, I distinguish between mere sensations like seeing pitch black all around you and perceptual experiences like seeing a red apple. Both have sensory phenomenology in presenting us with sensory qualities like colors, being analog in Dretske's sense, and being (...) fine-grained. However, only the latter have furthermore a perceptual phenomenology characterized by objectification and related dualities of perspectivality/completion and variation/constancy. Second, I elaborate on the reasons for thinking that both mere sensations and perceptual experiences need to be distinguished from accompanying seemings that passively assign things into conceptual categories and thereby tell you something about them. For example, when you look at a red apple and have the relevant recognitional abilities it will also normally seem to you that this is an apple. Finally, I argue that the best version of the popular dogmatist view about evidence is one which claims that it's neither experiences nor seemings by themselves, but rather the right sorts of composites of experiences and seemings that provide evidence.

Naïve Realists hold that perceptual experience is a conscious relation to an object and its property-instances. In contrast, Representationalists hold that it is a conscious representational state with content, something which is accurate or inaccurate in certain conditions. The most common versions of Representationalism take perceptual content to be either general (Generalism) or singular in the object-place and otherwise consisting of attribution of properties (Singularism/Attributionism). Susanna Schellenberg has recently developed a version on which perceptual content is singular even in the (...) property-place in containing a de re mode of presentation of a property-instance (Particularism) (Schellenberg 2018). Particularism is explicitly motivated by its ability to capture certain Naïve Realist insights and it would be genuine progress if it were the best version of Representationalism. Then the debate between Naïve Realism and Representationalism would reduce to the debate over Disjunctivism. In this paper I show that Particularism faces a version of the problem of the Unity of Perceptual Content. Namely, its supporters haven’t told us how objects can be bound together with property-instances into a content such that it represents them and has accuracy-conditions. Furthermore, I argue that Particularists face an in-principle obstacle in solving it. In contrast, Attributionists can say that objects are bound together with properties into a content because the latter are attributed to the former. This establishes Attributionism as the only Representationalist game in town. But Attributionism can’t capture all Naïve Realist insights that the Particularists are after. Thus, the debate between Naïve Realism and Representationalism doesn’t reduce to the debate over Disjunctivism. (shrink)

Many philosophers and scientists take perceptual experience, whatever else it involves, to be representational. In ‘The Silence of the Senses’, Charles Travis argues that this view involves a kind of category mistake, and consequently, that perceptual experience is not a representational or intentional phenomenon. The details of Travis’s argument, however, have been widely misinterpreted by his representationalist opponents, many of whom dismiss it out of hand. This chapter offers an interpretation of Travis’s argument from looks that it is argued presents (...) a genuine and important challenge to orthodox representational views of experience. Whilst this challenge may not be insurmountable, it places a substantial burden upon the representationalist to explain not only how experiences come to have the contents that they do, but how those contents come to feature in our conscious mental lives.

This paper responds to critical comments by Christopher Hill, Ram Neta, and Nico Orlandi on my book The Unity of Perception: Content, Consciousness, Evidence (OUP 2018). It addresses questions about why analyzing mental states in terms of capacities is more explanatory powerful than analyzing them in terms of processes. It further develops my view of functions and their relation to mental capacities. It clarifies the internalist commitments of my externalist view of content, consciousness, and evidence. The topics addressed include further (...) the many-properties problem, the relation between what is perceived and what is represented, as well as the evidential transparency principle. (shrink)

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)

Perception grounds demonstrative reference, yields singular thoughts, and fixes the reference of singular terms. Moreover, perception provides us with knowledge of particulars in our environment and justifies singular thoughts about particulars. How does perception play these cognitive and epistemic roles in our lives? I address this question by exploring the fundamental nature of perceptual experience. I argue that perceptual states are constituted by particulars and discuss epistemic, ontological, psychologistic, and semantic approaches to account for perceptual particularity.

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)

I argue that perceptual consciousness is constituted by a mental activity. The mental activity in question is the activity of employing perceptual capacities, such as discriminatory, selective capacities. This is a radical view, but I hope to make it plausible. In arguing for this mental activist view, I reject orthodox views on which perceptual consciousness is analyzed in terms of peculiar entities, such as, phenomenal properties, external mind-independent properties, propositions, sense-data, qualia, or intentional objects.

Recently, the thesis that experience is fundamentally a matter of representing the world as being a certain way has been questioned by austere relationalists. I defend this thesis by developing a view of perceptual content that avoids their objections. I will argue that on a relational understanding of perceptual content, the fundamental insights of austere relationalism do not compete with perceptual experience being representational. As it will show that most objections to the thesis that experience has content apply only to (...) accounts of perceptual content on which perceptual relations to the world play no explanatory role. With austere relationalists, I will argue that perceptual experience is fundamentally relational. But against austere relationalists, I will argue that it is fundamentally both relational and representational. (shrink)

I argue that perceptual experience provides us with both phenomenal and factive evidence. To a first approximation, we can understand phenomenal evidence as determined by how our environment sensorily seems to us when we are experiencing. To a first approximation, we can understand factive evidence as necessarily determined by the environment to which we are perceptually related such that the evidence is guaranteed to be an accurate guide to the environment. I argue that the rational source of both phenomenal and (...) factive evidence lies in employing perceptual capacities that we have in virtue of being perceivers. In showing that both kinds of evidence have the same rational source, I provide a unified account of perceptual evidence and its rational source in perceptual experience. (shrink)

This paper addresses the title question and provides an argument for the conclusion that so-called phenomenal intentionality, in both its relational and non-relational construals, cannot be identified with intentionality meant as the property for a mental state to be about something. A main premise of the argument presented in support of that conclusion is that a necessary requirement for a property to be identified with intentionality is that it satisfy the features taken to be definitory of it, namely: the possible (...) non-existence of the intentional object and aspectuality. By taking this premise on board, I attempt to show that phenomenal intentionality cannot be identified with intentionality because, appearances notwithstanding, it ultimately satisfies neither of the two above mentioned features.

The most common form of direct realism is Phenomenological Direct Realism. PDR is the theory that direct realism consists in unmediated awareness of the external object in the form of unmediated awareness of its relevant properties. I contrast this with Semantic Direct Realism, the theory that perceptual experience puts you in direct cognitive contact with external objects but does so without the unmediated awareness of the objects’ intrinsic properties invoked by PDR. PDR is what most understand by direct realism. My (...) argument is that, under pressure from the arguments from illusion and hallucination, defenders of intentionalist theories, and even of relational theories, in fact retreat to SDR. I also argue briefly that the sense-datum theory is compatible with SDR and so nothing is gained by adopting either of the more fashionable theories. (shrink)

Phenomenal character is the what-it's-likeness of subjective experience. I develop an ontology of phenomenal feel as process. My being in some phenomenal state R is the process of my instantiating R’s neurological correlate. The ontology explains why we have asymmetric epistemic access to phenomenal characters: the ontological ground for the subjective or first-personal stance is different from the ontological ground for the objective or third-personal stance. I end by situating my account in debates about physicalism.

A perceptual experience of a given object seems to make the object itself present to the perceiver’s mind. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) provides a better account of this phenomenological directness of perceptual experience than does the content view (the view that to perceive is to represent the world to be a certain way). But the naïve realist account of this phenomenology (...) has a conspicuous shortcoming: it explains the phenomenological directness of veridical perceptual experiences but not of hallucinations. Conversely, I maintain that a particular variety of the content view provides a unified account of the phenomenological directness of both veridical and hallucinatory experiences. If so, then contrary to what is often assumed, the phenomenological facts concerning perceptual experience are explained better by the content view than by naïve realism, and consequently, we have a compelling reason to prefer the content view to naïve realism.

When you have a perceptual experience of a given physical object that object seems to be immediately present to you in a way it never does when you consciously think about or imagine it. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) can provide a satisfying account of this phenomenological directness of perceptual experience while the content view (the view that to perceive is to (...) represent the world to be a certain way) cannot. I argue that this claim is false. Specifically, I maintain that the only acceptable naïve realist account of the relevant phenomenology is circular and that the content view can provide a similar account. In addition, I maintain that a certain specific variety of the content view provides a non-circular and thus more satisfactory account of this phenomenology. If so, then contrary to what is commonly assumed there are powerful phenomenological grounds for preferring the content view to naïve realism. (shrink)

Naïve realism, the view that perceptual experiences are irreducible relations between subjects and external objects, has intuitive appeal, but this intuitive appeal is sometimes thought to be undermined by the possibility of certain kinds of hallucinations. In this paper, I present the intuitive case for naïve realism, and explain why this intuitive case is not undermined by the possibility of such hallucinations. Specifically, I present the intuitive case for naïve realism as arguing that the only way to make sense of (...) the phenomenal character associated with perceptual experiences is by means of a naïve realist ontology. I then explain why this intuitive argument is not undermined by the possibility of hallucinatory experiences that possess the phenomenal character associated with perceptual experiences but, being hallucinations, do not have the ontological nature specified by naïve realism.

Externalist representationalism is touted as a superior rival to naïve realism, and yet a careful analysis of the externalist representationalist's analysis of our ordinary perceptual experiences shows the view to be far closer to naïve realism than we might have expected. One of the central advertised benefits of representationalist views in general is that they are compatible with the idea that ordinary, illusory and hallucinatory perceptual experiences are of the same fundamental kind. Naïve realists are forced to deny the ‘common (...) fundamental kind claim’ and adopt disjunctivism. However, I argue that externalist representationalism is also a version of disjunctivism. Consequently, one of the main rivals to naïve realism turns out not to be a rival at all. (shrink)

Externalist representationalists claim that the phenomenal character of a visual perceptual experience is determined by the representational content of that experience. Their deployment of the idea that perceptual experience is transparent shows that they account for representational content with reference to the properties which are represented – the properties out there in the world. I explain why this commits the externalist representationalist to objectivism and realism about colour properties. Colour physicalism has proved to be the position of choice for externalist (...) representationalists. However, my aim in this paper is to demonstrate that the proponent of the view which combines externalist representationalism with colour physicalism is unable to account for the phenomenal character of colour hallucination.

All non-relational views of perceptual experience face Jackson's famous many-property problem. I argue that the original problem, and the existing responses to it, have focused too closely on the controversial terminology for which adverbialism is best known. We can also direct Jackson's many-property problem explicitly onto the adverbialist's metaphysics, generating a new challenge. The responses contemporary adverbialists and non-relationalists have made to the original objection are not successful against this challenge. We need a new non-relational account. I sketch an outline (...) of a new theory, and motivate the view by explaining how it can respond successfully to this additional challenge. -/- . (shrink)

Awareness is a two-place determinable relation some determinates of which are seeing, hearing, etc. Abstract objects are items such as universals and functions, which contrast with concrete objects such as solids and liquids. It is uncontroversial that we are sometimes aware of concrete objects. In this paper I explore the more controversial topic of awareness of abstract objects. I distinguish two questions. First, the Existence Question: are there any experiences that make their subjects aware of abstract objects? Second, the Grounding (...) Question: if an experience makes its subject aware of an abstract object, in virtue of what does it do so? I defend the view that intuitions, specifically mathematical intuitions, sometimes make their subjects aware of abstract objects. In defending this view, I develop an account of the ground of intuitive awareness. (shrink)

Hallucination: Philosophy and Psychology is an edited MIT press collection that contributes to the philosophy of perception. This collection is a significant addition to the literature both for its excellent choice of texts, and its emphasis on the case of hallucinations. Dedicating a volume to hallucinatory phenomena may seem somewhat peculiar for those not entrenched in the analytic philosophy of perception, but it is easy enough to grasp their significance. Theories of perception aim to give a fundamental characterization of perceptual (...) experience, which are experiences with a sensory phenomenal character. Such perceptual experiences include cases of successfully perceiving something, but also some cases of merely seeming to perceive. This is because prima facie, some cases of seeming to perceive are more than merely thinking that one does ; they are cases of misperceiving. Hallucinations are .. (shrink)

Many philosophers have held that perceptual experience is fundamentally a matter of perceivers being in particular representational states. Such states are said to have representational content, i.e. accuracy or veridicality conditions, capturing the way that things, according to that experience, appear to be. In this thesis I argue that the case against representationalism — the view that perceptual experience is fundamentally and irreducibly representational — that is set out in Charles Travis’s ‘The Silence of the Senses’ (2004) constitutes a powerful, (...) but much misunderstood and neglected argument against this prevailing philosophical orthodoxy. -/- In chapter 2, I present an interpretation of Travis’s arguments that poses a dilemma for the representationalist concerning the indeterminacy and availability of perceptual content. Chapters 3 and 4 evaluate a variety of arguments in favour of such content based upon the nature of appearances, or ‘looks’, including those by Byrne (2009), Siegel (2010) and Schellenberg (2011b), each of which I find to be problematic. Finally, chapters 5 and 6 examine the relationship between representational content and phenomenal character, i.e. what perceptual experience is subjectively like, outlining some potential responses to Travis’s anti-representationalism. These include the external individuation of content and self-knowledge, and the operation of perceptual discriminatory capacities (the latter of which does not necessarily favour a representationalist account of experience). -/- I conclude that Travis’s arguments establish substantive constraints upon the nature and role of perceptual content. Moreover, I argue that the debate centres less upon the existence of such content than its explanatory role, particularly in relation to phenomenal character and the contents of other mental states: belief, intention, thought, knowledge, and so on. This in turn highlights the need for representationalists to better clarify the role of the contents their theories posit, and why such theories constitute a better explanation of the relevant phenomena than the corresponding non-representational view..

My dissertation contributes to a central and ongoing debate in the philosophy of perception about the fundamental nature of perceptual states. Such states include cases like seeing, hearing, or tasting as well as cases of merely seeming to see, hear, or taste. A central question about perceptual states arises in light of misperceptual phenomena. A commonsensical view of perceptual states construes them as simply relating us to the external and mind independent objects. But some misperceptual cases suggest that these states (...) fall short of contact with the world. The result is that perceptual states are either thought to fundamentally consist in a highest common factor that falls short of perceptual contact with the world, or are thought to be disjunctive in nature, with some cases involving perceptual contact, and others receiving a different analysis. Contrary to these views, I argue that no misperceptual cases compromise perceptual contact with worldly objects, so perceptual states should be understood as relations to the external and mind-independent world. I call this view I defend Pure Relationalism, and the view of misperceptual cases that makes pure relationalism possible Illusionism. (shrink)
