A preview of my book *Perception*. Discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, (...) suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

While philosophers of perception develop representational theories of olfactory experiences, there are doubts regarding whether features of olfactory perception can be accommodated within the representationalist framework. In particular, it is argued that the function of olfaction is not to represent stimuli but rather to evaluate it. The paper claims that the major representational accounts of olfaction have problems in accommodating the evaluative aspects of olfactory phenomenology. However, an alternative position, named “olfactory evaluativism,” is proposed which is free of these problems (...) and may serve as a foundation for further developments of representational approach to olfactory experiences. (shrink)

One of the crucial characteristics of the olfactory modality is that olfactory experiences commonly present odours as pleasant or unpleasant. Indeed, because of the importance of the hedonic aspects of olfactory experience, it has been proposed that the role of olfaction is not to represent the properties of stimuli, but rather to generate a valence-related response. However, despite a growing interest among philosophers in the study of the chemical senses, no dominant theory of sensory pleasure has emerged in the case (...) of human olfaction. The aim of this paper is to develop an argument based on the way in which olfactory valence is neurally encoded; one that demonstrates an advantage of the indicative representational approach to olfactory valence over approaches that characterise valence in terms of desires or commands. The argument shows that it is plausible to understand olfactory valence, at least in part, in terms of indicative representations. (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.

Interactionists hold that minds are non-physical objects that interact with brains. The neural discernment problem for interactionism is that of explaining how non-physical minds produce behavior and cognition by exercising different causal powers over physiologically similar neurons. This paper sharpens the neural discernment problem and proposes two interactionist models of mind-brain interaction that solve it. One model avoids overdetermination while the other respects the causal closure of the physical domain.

Reductive physicalists typically accept the causal argument for their view. On this score, Tiehen parts ways with his fellow reductive physicalists. Heretically, he argues that reductive physicalists should reject the causal argument. After presenting Tiehen's challenge, I defend the orthodoxy. Although not myself a reductive physicalist, I show how reductive physicalists can resist this challenge to the causal argument. I conclude with a positive suggestion about how reductive physicalists should use the causal argument.

Develops an empirical argument against naive realism-disjunctivism: if naive realists accept "internal dependence", then they cannot explain the evolution of perceptual success. Also presents a puzzle about our knowledge of universals.

Some recently popular accounts of perception account for the phenomenal character of perceptual experience in terms of the qualities of objects. My concern in this paper is with naturalistic versions of such a phenomenal externalist view. Focusing on visual spatial perception, I argue that naturalistic phenomenal externalism conflicts with a number of scientific facts about the geometrical characteristics of visual spatial experience.

This paper argues that a common form of representationalism has trouble accommodating empirical findings about visual space perception. Vision science tells us that the visual system systematically gives rise to different experiences of the same spatial property. This, combined with a naturalistic account of content, suggests that the same spatial property can have different veridical looks. I use this to argue that a common form of representationalism about spatial experience must be rejected. I conclude by considering alternatives to this view.

Recent philosophy has seen a resurgence of the realist view of sensible qualities such as colour. The view holds that experienced qualities are properties of the objects in the physical environment, not mentally instantiated properties like qualia or merely intentional, illusory ones. Some suggest that this move rids us of the explanatory gap between physical properties and the qualitative features of consciousness. Others say it just relocates the problem of qualities to physical objects in the environment, given that such qualities (...) cannot be derived from the non-qualitative properties of objects, and it does not resolve the problem of consciousness either. I argue that such an outcome is welcome: if the physical world is full of explanatory gaps, then the mind–body explanatory gap is not so special. Moreover, the explanatory gaps regarding qualities of objects are less puzzling than the brain-qualia gap. In order to counter the usual worries concerning realism about objective qualities, I introduce ‘imperfect realism’ as an alternative to colour pluralism and complex reductionism, which accommodates realism in the face of widespread perceptual error. I conclude with a discussion of how this ‘multiple-gaps view’ sits better with a naturalistic framework compared to the Galilean-Cartesian account of qualities. (shrink)

Andreas Mogensen has recently argued that the current debate over evolutionary debunking in ethics is mired in confusion due to a simple fallacy committed by debunkers and uncritically taken on board by their opponents. I argue that no party to this debate is involved in the type of confusion and fallacy Mogensen has in mind, which he himself notes would be an absurd and outlandish mistake for anyone to make in other domains. Debunkers do plausibly commit an error in their (...) explanatory claims about our moral beliefs, and it is related to an issue Mogensen discusses, but it is not the confusion and fallacy he identifies.

We motivate five constraints on theorizing about sensory experience. We then propose a novel form of naturalistic intentionalism that succeeds where other theories fail by satisfying all of these constraints. On the proposed theory, which we call structure matching tracking intentionalism, brains states track determinables. Internal structural features of those states select determinates of those determinables for presentation in experience. We argue that this theory is distinctively well-positioned to both explain internal-phenomenal structural correlations and accord external features a role in (...) fixing phenomenology. In addition, we use the theory to shed light on how one comes to experience “missing shades”. (shrink)

It is common for an object to present different colour appearances to different perceivers, even when the perceivers and viewing conditions are normal. For example, a Munsell chip might look unique green to you and yellowish green to me in normal viewing conditions. In such cases, there are three possibilities. Ecumenism: both experiences are veridical. Nihilism: both experiences are non-veridical. Inegalitarianism: one experience is veridical and the other is non-veridical. Perhaps the most important objection to inegalitarianism is the ignorance objection, (...) according to which inegalitarianism should be rejected because it is committed to the existence of unknowable colour facts. The goal of this paper is to show that ecumenists are also committed to unknowable colour facts. More specifically, I argue that, with the exception of colour eliminativism, all major philosophical theories of colour are committed to unknowable colour facts. (shrink)

According to a familiar modern view, color and other so-called secondary qualities reside only in consciousness, not in the external physical world. Many have argued that this “Galilean” view is the source of the mind-body problem in its current form. This paper critically examines a radical alternative to the Galilean view, which has recently been defended or sympathetically discussed by several philosophers, a view I call “anti-modernism.” Anti-modernism holds, roughly, that the modern Galilean scientific image is incomplete – in particular, (...) it leaves out certain irreducible qualitative properties, such as colors – and that we can solve (or dissolve) the hard problem of consciousness by accepting these properties as objective features of the external physical world. I argue, first, that anti-modernism cannot fulfill its promise. Even if the outer world is resplendent with primitive colors, color experience remains a mystery. Second, I argue that the theoretical costs of accepting irreducible colors in the world are enormous. Even if irreducible colors in the world could dispel the mysteries surrounding consciousness, the theoretical benefit would not be worth the cost. If the problems of consciousness and color require that we posit irreducible properties somewhere, it would be far more plausible to accept irreducible phenomenal properties on the side of the subject, and to reject irreducible colors on the side of the object.

This paper defends a non-reductive realist view of the sensible qualities—roughly, the view that the sensible qualities are really instantiated by the external objects of perception, and not reducible to response-independent physical properties or response-dependent relational properties. I begin by clarifying and motivating the non-reductive realist view. I then consider some familiar difficulties for the view. Addressing these difficulties leads to the development and defence of a general theory, inspired by Russellian Monist theories of consciousness, of how the sensible qualities (...) relate to physical reality. I conclude by showing how this theory, which I call ‘Secondary Quality Russellian Monism’, resolves the most significant difficulties for the non-reductive realist view of the sensible qualities.

Some truths about color are knowable a priori. For example, it is knowable a priori that redness is not identical to the property of being square. This extremely modest and plausible claim has significant philosophical implications, or so I shall argue. First, I show that this claim entails the falsity of standard forms of color functionalism, the view that our color concepts are functional concepts that pick out their referents by way of functional descriptions that make reference to the subjective (...) responses of perceivers. I then argue that, while some sophisticated forms of color functionalism can accommodate the a priori knowability of a truth like “redness is not identical to squareness,” they can only do so by abandoning color realism, the thesis that colors are instantiated by external material objects. In practice, color functionalists are almost invariably color realists. Thus, given extremely modest assumptions concerning what can be known a priori about color, we should conclude that color functionalism, at least in its typical realist form, is false. (shrink)

Imagine your mirror‐inverted counterpart on Mirror Earth, a perfect mirror image of Earth. Would her experiences be the same as yours, or would they be phenomenally mirror‐inverted? I argue, first, that her experiences would be phenomenally the same as yours. I then show that this conclusion gives rise to a puzzle, one that I believe pushes us toward some surprising and philosophically significant conclusions about the nature of perception. When you have a typical visual experience as of something to your (...) left, the following three claims seem very plausible: (1) No one could have an experience phenomenally just like yours without thereby having an experience as of something to her left. (2) Your experience is veridical. (3) Your experience doesn't differ from that of your mirror‐inverted counterpart with respect to veridicality. But (1)‐(3) jointly contradict the claim that you and your mirror‐inverted counterpart would have the same experiences. I argue that any viable response to this puzzle will embrace the following disjunction: either there is a degree of independence between perceptual phenomenology and representational content, contrary to popular intentionalist views of perception, or spatial subjectivism is true, where spatial subjectivism is the view that the spatial properties presented in perception are either mind‐dependent or illusory.

Bodily pain strikes many philosophers as deeply paradoxical. The issue is that pains seem to bear both physical characteristics, such as a location in the body, and mental characteristics, such being mind-dependent. In this paper I clarify and address this alleged paradox of pain. I begin by showing how a further assumption, Objectivism, the thesis that what one feels in one’s body when one is in pain is something mind-independent, is necessary for the generation of the paradox. Consequently, the paradox (...) can be avoided if one rejects this idea. However, doing so raises its own difficulties, for it is not obvious how anything can possess all of the features we typically associate with bodily pain. To address this puzzle and finally put the paradox of pain to rest, I develop the Embodied View, a novel metaphysical account on which pains are constitutively mind-dependent features of parts of a subject’s body. (shrink)

Relationalism holds that perceptual experiences are relations between subjects and perceived objects. But much evidence suggests that perceptual states can be unconscious. We argue here that unconscious perception raises difficulties for relationalism. Relationalists would seem to have three options. First, they may deny that there is unconscious perception or question whether we have sufficient evidence to posit it. Second, they may allow for unconscious perception but deny that the relationalist analysis applies to it. Third, they may offer a relationalist explanation (...) of unconscious perception. We argue that each of these strategies is questionable. (shrink)

Many theorists maintain that perceptual experience exhibits the what is often called the phenomenology of particularity: that in perceptual experience it phenomenally seems that there are particular things. Some urge that this phenomenology demands special accounts of perception on which particulars somehow constitute perceptual experience, including versions of relationalism, on which perception is a relation between perceivers and particular perceived objects, or complex forms of representationalism, on which perception exhibits demonstrative or special particular-involving types of content. I argue here that (...) no such account required. I develop and defend a novel account of such phenomenology, grounded in the higher-order theory of consciousness. In short, this view holds that the phenomenology of particularity arises because suitable higher-order states make it appear to one that one is in perceptual relations to particulars, even if perception is not in any way constituted by particulars. I argue that this account has many advantages and avoids problems that other theories of such phenomenology face. (shrink)

Representationalism holds that a perceptual experience's qualitative character is identical with certain of its representational properties. To date, most representationalists endorse atomistic theories of perceptual content, according to which an experience's content, and thus character, does not depend on its relations to other experiences. David Rosenthal, by contrast, proposes a view that is naturally construed as a version of representationalism on which experiences’ relations to one another determine their contents and characters. I offer here a new defense of this holistic (...) representationalism, arguing that some objections to atomistic views are best interpreted as supporting it. (shrink)

Perceptions are externally-directed—they present us with a mind-independent reality, and thus contribute to our abilities to think about this reality, and to know what is objectively the case. But perceptions are also internally-dependent—their phenomenologies depend on the neuro-computational properties of the subject. A good theory of perception must account for both these facts. But naive realism has been criticized for failing to accommodate internal-dependence. This paper evaluates and responds to this criticism. It first argues that a certain version of naive (...) realism, often called “selectionism”, does indeed struggle with internal-dependence. It then develops an alternate version of naive realism which does not. This alternate version, inspired by an idea of Martin’s, accommodates the internal-dependence of perceptions by recognizing the role that the subject’s neuro-computational properties play in shaping perceptual phenomenology. At the same time, it retains the distinctive naive realist account of the external-directedness of perceptions. (shrink)

Unconscious perceptions have recently become a focal point in the debate for and against naive realism. In this paper I defend the naive realist side. More specifically, I use an idea of Martin’s to develop a new version of naive realism—neuro-computational naive realism. I argue that neuro-computational naive realism offers a uniform treatment of both conscious and unconscious perceptions. I also argue that it accommodates the possibility of phenomenally different conscious perceptions of the same items, and that it can answer (...) a further challenge to naive realism raised by Berger and Nanay.

The IASP definition of 'pain' defines pain as a subjective experience. The Note accompanying the definition emphasizes that as such pains are not to be identified with objective conditions of body parts (such as actual or potential tissue damage). Nevertheless, it goes on to state that a pain "is unquestionably a sensation in a part or parts of the body, but it is also always unpleasant and therefore also an emotional experience." This generates a puzzle that philosophers have been well (...) familiar with: how to understand our utterances and judgments attributing pain to body parts. (The puzzle is of course general extending to all sensations routinely located in body parts.) The present work tackles this puzzle. I go over various options specifying the truth-conditions for pain attributing judgments, and at the end make my own recommendation which is an adverbialist, qualia-friendly proposal with completely naturalistic credentials that is also compatible with forms of weak intentionalism. The results are generalizable to other bodily sensations and can be used to illustrate, quite generally, the viability of a qualia-friendly adverbialist (but naturalist and weakly intentionalist) account of perception. (shrink)

I distinguish between two claims of transparency of experiences. One claim is weaker and supported by phenomenological evidence. This I call the transparency datum. Introspection of standard perceptual experiences as well as bodily sensations is consistent with, indeed supported by, the transparency datum. I formulate a stronger transparency thesis that is entailed by representationalism about experiential phenomenology. I point out some empirical consequences of strong transparency in the context of representationalism. I argue that pain experiences, as well as some other (...) similar experiences like itches, tickles, orgasms, hedonic valence, etc., are not transparent in this strong sense. Hence they constitute empirical counterexamples to representationalism. Given that representationalism is a general metaphysical doctrine about all experiential phenomenology for good reasons, I conclude that representationalism about phenomenal consciousness is false. Then, I outline a general framework about how the introspection of phenomenal qualities in perceptual experience works in light of the transparency datum, but consistent with the rejection of strong transparency. The result is a form of qualia realism that is naturalist and intentionalist, and has close affinities to the adverbialist views developed in the latter part of the last century. I then apply this framework to pain experiences and their bodily locations. (shrink)

Many favor representationalism about color experience. To a first approximation, this view holds that experiencing is like believing. In particular, like believing, experiencing is a matter of representing the world to be a certain way. Once you view color experience along these lines, you face a big question: do our color experiences represent the world as it really is? For instance, suppose you see a tomato. Representationalists claim that having an experience with this sensory character is necessarily connected with representing (...) a distinctive quality as pervading a round area out there in external space. Let us call it “sensible redness” to highlight the fact that the representation of this property is necessarily connected with the sensory character of the experience. Is this property, sensible redness, really co-instantiated with roundness out there in the space before you? (shrink)

[Special issue honoring Nikola Grahek] Representationalism in philosophy of perception has become more or less the dominant view. There are various versions of it not all of which are motivated by the same set of concerns. Different metaphysical and epistemological agendas are at work in different strands of the movement. In this paper, I will focus on what has come to be known as strong representationalism. This view has reductive and non-reductive versions, which are usually paired with realist and irrealist (...) versions respectively. First, I will develop a simple, largely empirical, argument against the realist reductive version. Later, rather more briefly, I will extend the argument to cover irrealist representationalism. (shrink)

In “The Meta-Problem of Consciousness”, David Chalmers briefly raises a problem about how the connection between consciousness and our verbal and other behavior appears “lucky”. I raise a counterexample to Chalmers’s formulation of the problem. Then I develop an alternative formulation. Finally, I consider some responses, including illusionism about consciousness.

I raise some objections to the theory presented in *Outside Color*.

In this chapter, Pautz raises a puzzle about spatial experience for phenomenal internalists like Ned Block. If an accidental, lifelong brain-in-the-void (BIV) should have all the same experiences as you, it would have an experience as of items having various shapes, and be able to acquire concepts of those shapes, despite being cut off from real things with the shapes. Internalists cannot explain this by saying that BIV is presented with Peacocke-style visual field regions having various shapes, because these would (...) have to be non-physical sense data. They might instead explain this by saying that BIV “phenomenally represents” various shape properties. But since BIV lacks any interesting physical relations to shapes, this would imply that phenomenally representation is an irreducible relation. (shrink)

In “Radical Interpretation” (1974), David Lewis asked: by what constraints, and to what extent, do the non-intentional, physical facts about Karl determine the intentional facts about him? There are two popular approaches: the reductive externalist program and the phenomenal intentionality program. I argue against both approaches. Then I sketch an alternative multistage account incorporating ideas from both camps. If we start with Karl's conscious experiences, we can appeal to Lewisian ideas to explain his other intentional states. This account develops the (...) multistage Lewisian approach presented at the end of my earlier "Does Phenomenology Ground Mental Content?" (2013). (shrink)

Affective experiences motivate and rationalize behavior in virtue of feeling good or bad, or their valence. It has become popular to explain such phenomenal character with intentional content. Rejecting evaluativism and extending earlier imperativist accounts of pain, I argue that when experiences feel bad, they both represent things as being in a certain way and tell us to see to it that they will no longer be that way. Such commands have subjective authority by virtue of linking up with a (...) relevant background concern. The imperative content explains but doesn’t constitute world-directed motivation. It also rationalizes action indirectly, by giving rise to an affective seeming that represents the situation as calling for the authoritatively commanded behavior. One experience feels worse than another if its content tells us to bear a higher opportunity cost to comply with the command. Finally, experience-directed motivation is contingent on our being attitudinally (dis)pleased with the character of our experience. (shrink)

This paper develops a new argument from consciousness to theism: the argument from psychophysical harmony. Roughly, psychophysical harmony consists in the fact that phenomenal states are correlated with physical states and with one another in strikingly fortunate ways. For example, phenomenal states are correlated with behavior and functioning that is justified or rationalized by those very phenomenal states, and phenomenal states are correlated with verbal reports and judgments that are made true by those very phenomenal states. We argue that psychophysical (...) harmony is strong evidence for theism (or, at least, strong evidence against atheism in its standard naturalistic form). (shrink)

It is often thought that sensible qualities such as colours do not exist as properties of physical objects. Focusing on the case of colour, I discuss two views: the Galilean view, according to which colours do not exist as qualities of physical objects, and the naive view, according to which colours are, as our perception presents them to be, qualities instantiated by physical objects. I argue that it is far from clear that the Galilean view is better than the naive (...) view. Given the arguments in this paper, the naive view ought to be taken seriously. The discussion here appeals especially to theorists who, like Goff, are already convinced that the quantitative language of physical science fails to capture all qualities. (shrink)

According to pure imperativism, pain experiences are experiences of a specific phenomenal type that are entirely constituted by imperative content. As their primary argument, proponents of imperativism rely on the biological role that pain experiences fulfill, namely, the motivation of actions whose execution ensures the normal functioning of the body. In the paper, I investigate which specific types of action are of relevance for an imperative interpretation and how close their link to pain experiences actually is. I argue that, although (...) imperative theories constitute an apparently promising version of strong intentionalism, they cannot provide an imperative content that meets their own criteria of both sufficiency and necessity. I further argue that this issue cannot be solved by impure imperative theories either. (shrink)
