1 Grasping Properties I will present an argument for property dualism. The argument employs a distinction between having a concept of a property and grasping a property via a concept. If you grasp a property P via a concept C, then C is a concept of P. But the reverse does not hold: you may have a concept of a property without grasping that property via any concept. If you grasp a property, then your cognitive relation to that property (...) is more intimate then if you just have some concept or other of that property. To grasp a property is to understand what having that property essentially consists in. (shrink)

What is the connection between having a phenomenal property and knowing that one has that property? A traditional view on the matter takes the connection to be quite intimate. Whenever one has a phenomenal property, one knows that one does. Recently most authors have denied this traditional view. The goal of this paper is to defend the traditional view. In fact, I will defend something much stronger: I will argue that what it is for a property to be (...) phenomenal is for it to be a property one must know oneself to have when on has it. As we will see, this theory has a number of surprising and welcome upshots, suggesting that the traditional view has been unjustly maligned. (shrink)

According to non-reductive physicalism, mental properties of the phenomenal sort are essentially different from physical properties, and cannot be reduced to them. This being a quarrel about properties, I draw on the categorical / dispositional distinction to discuss this non-reductive claim. Typically, non-reductionism entails a categorical view of phenomenal properties. Contrary to this, I will argue that phenomenal properties, usually characterized by what it is like to have them, are mainly the manifestation (...) of dispositional properties. This paper is thus divided into two parts. In the first part, after tracing a working distinction between categorical and dispositional properties, I argue that there is a form of incoherence looming behind the idea of taking phenomenal properties as categorical. In the second part, I argue in favor of the view that phenomenal properties are dispositional properties with an essential manifestation. This interpretation allows us to broaden dispositionalism so as to include the sciences of mind, thus ultimately favoring a physicalist view on the mind. (shrink)

We experience the intuition of distinctness when, for example, we attend introspectively to the phenomenal redness of a current visual sensation and it seems to us that that very property could not literally be a physical property of neural activity in a certain tiny region of our brain. The book begins by arguing that the intuition of distinctness underlies certain otherwise puzzling attitudes manifested in debates both inside and outside philosophy about whether physicalism (or materialism) can accommodate phenomenal (...) properties (or qualia). It then argues systematically against the dualist suggestion that the intuition of distinctness gives us reason to reject the physicalist view that phenomenal properties are physical, and to adopt property dualism instead. In the course of the argument, it defends an unorthodox version of representationalism and offers positive accounts of what makes our introspective knowledge of phenomenal properties special, how introspection could tell us that an introspected property is physical, and what the subjectivity of phenomenal properties could be. Finally, after critically surveying previous attempts to account for the intuition of distinctness consistently with physicalism, it elaborates a novel explanation of the intuition of distinctness. The intuition arises because introspection is, in a certain way, conceptually encapsulated, as a result of which we are unable to do something that we can do in the case of every other kind of identity claim that we believe or entertain, and therefore unable to believe, or even to imagine believing, that an introspected phenomenal property is physical.

What assumptions are built into the claim that experience has “phenomenal properties,” and could these assumptions turn out to be false? I consider the issue specifically for the similarity relations between experiences: for example, experiences of different shades of red are more similar to each other than an experience of red and an experience of green. It is commonly thought that we have a special kind of epistemic access to experience that is more secure than our access to (...) the external environment. In the first part of the paper, I argue than one way of elucidating this claim is especially plausible—that systematic error, of the kind subjects make about the external environment in traditional “skeptical” scenarios, is not conceivable for introspection of experience, including for our knowledge of similarity relations. I argue that focusing on similarity relations gives us a more interesting version of the argument than for other forms of experiential introspection. Then in the second part of the paper I describe an example, inspired by a similar case due to Sydney Shoemaker, in which a subject, despite being fully rational and attentive, apparently is systematically mistaken about the character of their experience in a surprising way. I argue that the example calls into question whether there are properties of experience satisfying the epistemic access constraint, and therefore whether experience has “phenomenal properties” in the intuitive sense.

This dissertation develops and defends a detailed realist, internalist account of qualia which is consistent with physicalism and which does not resurrect the epistemological 'myth of the Given.' In doing so it stakes out a position in the sparsely populated middle ground between the two major opposing factions on the problem of phenomenal consciousness: between those who think we have a priori reasons to believe that qualia are irreducible to the physical , and those who implicitly or explicitly treat (...) qualia as contentful but non-phenomenal physical properties . ;I present a minimal, non-question-begging definition of "qualia" and then use this definition in a reformulation of the argument from perceiver relativity which shows that qualia must, at least in humans, be properties of states of the central nervous system. That is, brain states do not simply indicate the colours of external objects---they instantiate phenomenal colours. Since brain states are not coloured in the same way as are external objects, I argue that to token phenomenal property F must be to be the first-person phenomenal sensation of F. I build on this position to argue that the phenomenal apprehension of qualia, is "given"---immediate, certain and private---but that qualia nevertheless do not provide an absolutely certain epistemological foundation since they do not constitute a set of indisputable propositions about facts. I then define what it would be for physicalism to be true of qualia, but argue that the main a priori arguments for and against qualia physicalism---including the logical possibility of zombies and the impossibility of epiphenomenalism---fail. Whether qualia are consistent with physicalism, I claim, is still an open question, answerable only when we discover in more detail how qualia depend upon the brain. ;Although strongly in sympathy with many commonsensical intuitions about qualia, this account stands in contrast to most influential extant theories of qualia, such as eliminativism , externalism , or property-dualism : I conclude the dissertation by using its results to argue explicitly against these three positions.

In this paper I give an overview of the recent developments in the phenomenalism – intentionalism debate and try to show that the proposed solutions of neither sides are satisfying. The claims and arguments of the two parties are rather vague and attribute to intentional and phenomenal properties either a too weak or a too strong relationship: too weak in the sense that they establish only mere coexistence, or too strong in the sense that they attribute some a (...) priori conceptual connection to intentional and phenomenal properties. I also compare these theories to other theories developed for solving the mind–body problem and argue that these former are much less elaborated. In the end of the paper I try to explain that all of this is not just a contingent feature of the topic, but has deep conceptual roots: intentionality and phenomenal consciousness are two quite distinct concepts on two quite distinct levels.

Can the physicalist consistently hold that representational content is all there is to sensory experience and yet that two perceivers could have inverted phenomenal spectra? Yes, if he holds that the phenomenal properties the inverts experience are dummy properties, not instantiated in the physical objects being perceived nor in the perceivers.

What are the relations between preattentive feature-placing and states of perceptual awareness? For the purposes of this paper, states of "perceptual awareness" are confined to the simplest possible exemplars: states in which one is aware of some aspect of the appearance of something one perceives. Subjective contours are used as an example. Early visual processing seems to employ independent, high-bandwidth, preattentive feature "channels", followed by a selective process that directs selective attention. The mechanisms that yield subjective contours are found very (...) early in this processing. An experiment by Greg Davis and Jon Driver is described; it seems to show that multiple subjective figures can be coded in these preattentive, parallel stages of visual processing. I propose that some of these preattentive states might register the very same differences that, were one aware of them, would be phenomenal differences. Some arguments pro and con on this possibility are assessed. (shrink)

“Strong AI” is the view that it is possible for an artificial agent to be mentally indistinguishable from human agents. Because the behavioral dispositions of artificial agents are determined by underlying dispositional systems, Strong AI seems to entail human behavioral dispositions are also determined by dispositional systems. It is, however, highly intuitive that non-dispositional, phenomenal properties, such as being in pain, at least partially determine certain human behavioral dispositions, like the disposition to take a pain killer. Consequently, Strong (...) AI seems to conflict with an intuitive view of phenomenal properties’ role in determining human behavioral dispositions. My goal here is not directly to evaluate this tension, but rather to clarify how dispositionalism in the metaphysics of properties bears on it. While a tempting thought is that dispositionalism fits well with Strong AI’s thoroughly dispositional account of human behavior, I argue that this thought does not hold for dispositionalism in general. In particular, I argue that combining a version of the “powerful qualities view” with certain dispositionalist conceptions of the will leads to a version of the intuitive view of phenomenal properties that is radically incompatible with Strong AI. I argue further that this view also raises a challenge for the weaker claim that an artificial agent could be behaviorally indistinguishable from a human agent. (shrink)

Sometimes when we describe our own sensory experiences we seem to attribute to experience itself the same sorts of familiar properties – such as shape or colour – as we attribute to everyday physical objects. But how literally should we understand such descriptions? Can there really be phenomenal elements or aspects to an experience which are, for example, quite literally square? This paper examines how these questions connect to a wide range of different commitments and theories about the (...) metaphysics of mind. In particular, I consider whether there may be phenomenological reasons to accept or reject the idea that there are elements or aspects of conscious experience itself which instantiate familiar spatial properties. I also explore how some general theses about the nature of empirical properties can motivate different answers to these questions. (shrink)

Sydney Shoemaker offers an account of color perception that attempts to do justice, within a functionalist framework, to the commonsense view that colors are properties of ordinary objects, to the existence of qualia, and to the possibility of spectrum inversions. Shoemaker posits phenomenal properties as dispositional properties of colored objects that explain how there can be intersubjective variation in the experience of a particular color. I argue that his account does not in fact allow for the (...) description of a spectrum inversion scenario, and that it cannot sustain a functionalist relationship between an object's color and its phenomenal properties. Functionalists must, however, come to terms with Shoemaker's recognition that intersubjective spectrum shifts are possible. (shrink)

In this essay I shall argue that the crucial assumptions of Kripke's argument, i.e. the collapse of the appearance/reality distinction in the case of phenomenal states and the idea of a qualitatively identical epistemic situation, imply an objective principle of identity for mental-state types. This principle, I shall argue, rather than being at odds with physicalism, is actually compatible with both the type-identity theory of the mind and Kripke's semantics and metaphysics. Finally, I shall sketch a version of the (...) type-identity theory. (shrink)

My interest in this chapter is to investigate this crossroad as applied to mental properties, considered powers. In particular, I scrutinize the possibility of taking the phenomenal property of feeling pain as a complex power or disposition. This possibility comes in handy in discussing panpsychism, the view that the ultimate elements of reality are phenomenal properties, which would ground physical properties as well.

The aim of this essay is to show that phenomenal properties are contentless modes of appearances of representational properties. The essay initiates with examination of the first-person perspective of the conscious observer according to which a “reference to I” with respect to the observation of experience is determined. A distinction is then drawn between the conscious observer and experience as observed, according to which, three distinct modifications of experience are delineated. These modifications are then analyzed with respect (...) to the content of experience and from this the ground of the distinction between phenomenal and representational properties is identified. (shrink)

Conservatives claim that all phenomenal properties are sensory. Liberals countenance non-sensory phenomenal properties such as what it’s like to perceive some high-level property, and what it’s like to think that p. A hallmark of phenomenal properties is that they present an explanatory gap, so to resolve the dispute we should consider whether experience has non-sensory properties that appear ‘gappy’. The classic tests for ‘gappiness’ are the invertibility test and the zombifiability test. I suggest (...) that these tests yield conflicting results: non-sensory properties lend themselves to zombie scenarios but not to inversion scenarios. Which test should we trust? Against Carruthers & Veillet (2011), I argue that invertibility is not a viable condition of phenomenality. In contrast, being zombifiable is credibly necessary and sufficient for phenomenality. I conclude that there are non-sensory properties of experience that are ‘gappy’ in the right way, and that liberalism is therefore the most plausible position. (shrink)

This work examines and critically evaluates the proposal that phenomenal properties, or the subjective qualities of experience, present a formidable challenge for the mind-body identity theory. Physicalism per se is construed as being ontically committed only to phenomena which can be made epistemically and cognitively available in the third person; observed and understood from within an objective frame of reference. Further, the identity relation between the mental and the physical is taken to be strict identity; the mental phenomena (...) in question just are the physical phenomena on which, ex hypothesi, they supervene. The problem of phenomenal properties has two basic strands. The first is the problem of how they are causally related to the physical; if they are not physical phenomena, by what causal mechanism might they be related to physical phenomena? One of the motivating considerations which led to the identity thesis was that it appeared to remove this problem. Our interest, however, is in evaluating the arguments which purport to establish that phenomenal properties are, indeed, distinct from the physical. (shrink)

Case studies in the psychophysics, modeling and localization of human vision are presented as an example of “hands-on” philosophy of the cognitive sciences. These studies also yield important results for familiar problems in philosophy of mind: the explanatory gap surrounding phenomenological feels is not closed by the kinds of investigations surveyed. However, the science is able to explain some sorts of phenomenological facts, such as why the human color space takes the form of the Munsell color solid, or why there (...) is a phenomenologically-pure yellow but not a phenomenologically-pure orange.

Reductive representationalism offers a promising route to an intelligible account of phenomenal consciousness. However, reductive representationalist accounts entail phenomenal externalism. Here I develop a new argument against phenomenal externalism and, by extension, standard reductive representationalism. I argue that the external determination of ‘here-and-now’ phenomenal properties entails an irreconcilable unintelligibility at the heart of reductive representationalist accounts. As reductive representationalism is motivated by the promise of rendering phenomenal experience intelligible, this criticism is fatal.

The purpose of this paper is to defend and further develop an account of the phenomenal character of perceptual experience. Rather than identify the phenomenal character with the intrinsic properties represented by perceptual experience (phenomenal externalism), my aim is to support the alternative claim that the phenomenal character of a perceptual experience is to be identified with the mode of presentation of environmental properties.

This chapter defends the property dualism argument. The term “semantic premise” mentioned is used to refers to an assumption identified by Brian Loar that antiphysicalist arguments, such as the property dualism argument, tacitly assume that a statement of property identity that links conceptually independent concepts is true only if at least one concept picks out the property it refers to by connoting a contingent property of that property. It is argued that, the property that does the work in explaining the (...) possibility of a posteriori identities need not be a first-order property of the referent in question. On his view, the property dualism argument requires only a weaker semantic premise, which allows that the property in question be a higher order property. A refined version of the property dualism argument is formulated, which uses the weaker premise, and defends the argument against various objections. (shrink)

According to phenomenal functionalism, whether some object or event has a given property is determined by the kinds of sensory experiences such objects or events typically cause in normal perceivers in normal viewing conditions. This paper challenges this position and, more specifically, David Chalmers’s use of it in arguing for what he calls virtual realism.

We argue that Block's charge of fallacy remains ungrounded so long as the existence of P-consciousness, as Block construes it, is independently established. This, in turn, depends on establishing the existence of “phenomenal properties” that are essentially not representational, cognitive, or functional. We argue that Block leaves this fundamental thesis unsubstantiated. We conclude by suggesting that phenomenal consciousness can be accounted for in terms of a hybrid set of representational and functional properties.

In this paper I argue that bodily pain, as a phenomenal property, is an essentially and substantial dispositional property. To this end, I maintain that this property is individuated by its phenomenal roles, which can be internal -individuating the property per se- and external -determining further phenomenal or physical properties or states. I then argue that this individuation allows phenomenal roles to be organized in a necessarily asymmetrical net, thereby overcoming the circularity objection to dispositionalism. (...) Finally, I provide reasons to argue that these roles satisfy modal fixity, as posited by Bird, and are not fundamental properties, contra Chalmers’ panpsychism. Thus, bodily pain can be considered a substantial dispositional property entrenched in non-fundamental laws of nature. (shrink)

The phenomenal powers view claims that phenomenal properties metaphysically necessitate their effects in virtue of how they feel, and thereby constitute non-Humean causal powers. For example, pain necessitates that subjects who experience it try to avoid it in virtue of feeling bad. I argue for this view based on the inconceivability of certain phenomenal properties necessitating different effects than their actual ones, their ability to predict their effects without induction, and their ability to explain their (...) effects without appeal to laws or regularities. I also offer a harmony argument according to which the view offers the best explanation for otherwise seemingly fortunate psychophysical regularities. I then outline the view’s main implications for the metaphysics of causation and philosophy of mind. (shrink)

Revelation, or the view that the essence of phenomenal properties is presented to us, is as intuitively attractive as it is controversial. It is notably at the core of defences of anti-physicalism. I propose in this paper a new argument against Revelation. It is usually accepted that low-level sensory phenomenal properties, like phenomenal red, loudness or brightness, stand in relation of similarity and quantity. Furthermore, these similarity and quantitative relations are taken to be internal, that (...) is, to be fixed by what their relata are. I argue that, under some plausible additional premises, no account of what grounds these relations in the essence of their relata is consistent with Revelation, at least if we take common phenomenological descriptions for granted. As a result, the plausibility of Revelation is undermined. One might however resist this conclusion by weakening the epistemic relation postulated between subjects and their phenomenal properties.

There are two main ways in which things with minds, like us, differ from things without minds, like tables and chairs. First, we are conscious--there is something that it is like to be us. We instantiate phenomenal properties. Second, we represent, in various ways, our world as being certain ways. We instantiate representational properties. Jeff Speaks attempts to make progress on three questions: What are phenomenal properties? What are representational properties? How are the (...) class='Hi'>phenomenal and the representational related? (shrink)

Phenomenal intentionality is a view about the representational content of conscious experiences that grounds the content of experiences in their phenomenal character. The view is motivated by evidence from introspection, as well as theoretical considerations and intuitions. This paper discusses one potential problem with the view. The view has difficulty accounting for the intentionality of color experiences. Versions of the view either fail to count things as part of the content of color experience that should be counted, resulting (...) in verdicts that some color experiences are inaccurate which should not be, or they admit properties as part of their contents that ought not to be admitted, resulting in color experiences being considered to be accurate when they ought not to be considered so. This is a problem because color predicates are usefully employed in sciences such as biology, cognitive science, and engineering. They are used in generalizations that take the form of laws governing the presence and behavior of properties. Scientific practice relies on the assumption that the laws governing how entities behave employ terms that refer to actual properties that entities really have. We should therefore assume that there is some consistent set of properties to which our color terms refer. (shrink)

The idea that there are features of or in our conscious experience that are, in some important sense, private has both a long history in philosophy and a large measure of intuitive attraction. Once this idea is in place, it will be very natural to assume that one can think and judge about one’s own private features. And it is then only a small step to the idea that we might communicate such thoughts and judgements about our respective private features (...) with each other. (shrink)

We maintain that no extant argument in favor of phenomenal external- ism is really convincing. PE is the thesis that the phenomenal properties of our experiences must be individuated widely insofar as they are constituted by worldly properties. We consider what we take to be the five best arguments for PE. We try to show that none of them really proves what it aims at proving. Unless better arguments in favor of phenomenal externalism show up (...) in the debate, we see no reason to relinquish an idea that seems intuitive and appeals to many cognitive sci- entists: that phenomenology is narrow, i.e., that phenomenal properties are intrinsic properties of our experiences. This idea grounds the opposite philosophical position, phenomenal internalism. (shrink)

This paper argues for the claim that the mental ontology required for what has been called the “Phenomenal Intentionality Theory” (PIT) should be understood in terms of mental events or episodes, not mental states that instantiate phenomenal properties because the former but not the latter has a kind of temporal shape. I begin by laying out the basic commitments of PIT. I then introduce the notion of “temporal shape” and defend the following simple but powerful argument: (1) (...) If conscious experiences are phenomenal mental states that instantiate phenomenal properties, then the phenomenal character of these experiences will lack a temporal shape. (2) The phenomenal character of conscious experience typically has a temporal shape. (3) Therefore, conscious experiences are not mental states that instantiate phenomenal properties. (shrink)

There is a prevalent assumption that the phenomenal character of a mental experience is an ontological property existing as part of the fabric of the world. This implies that the problem of explaining the phenomenal property of a mental experience is a metaphysical one. Contrary to this assumption, the present paper argues that phenomenal properties of mental experiences are the results of our epistemological perspectives of the world. Consequently, the paper contends that in developing issues for (...) African Philosophy of Mind, care must, ab initio, be taken to avoid the metaphysical pitfalls of considering phenomenal characters or properties of mental states to be part of the fabric of the world.

Phenomenal concepts are the concepts that we deploy when – but arguably not only when – we introspectively examine, focus on, or take notice of the phenomenal character of our experiences. They refer to phenomenal properties (or qualities) and they do so in a subjective (first-personal) and direct (non-relational) manner. It is through the use of such concepts that the phenomenal character of our experiences is made salient to us. Discourse about the nature of (...) class='Hi'>phenomenal concepts plays an important role in the philosophy of mind. For one, phenomenal concepts have been used to explain the epistemological relation that holds between a subject and her conscious mental states. Most prominently, however, discussions of phenomenal concepts figure in the on-going and multifaceted debate concerning the metaphysical status of consciousness. Even though some theorists have utilized phenomenal concepts in arguments purporting to show that consciousness is ontologically distinct from physical entities and processes, most accounts of phenomenal concepts are advanced having the opposite objective in mind: a proper articulation of the nature of phenomenal concepts, it is held, can defend the view that consciousness is physical against epistemic arguments to the contrary. The present entry focuses on the nature of phenomenal concepts as this is articulated and developed in attempts to defend the contention that conscious states are identical to (realized by, metaphysically necessitated by, or supervenient upon) physical states.

Cognition is not, and could not possibly be, entirely representational in character. There is also a phenomenal form of cognitive expression that registers the intrinsic properties of mental states themselves. Arguments against the reality of this intrinsic phenomenal dimension to mental experience have focused either on its supposed impossibility, or secondly, the non-appearance of any such qualities to introspection. This paper argues to the contrary, that the registration of cognitive state properties does take place independently of (...) representational content; and necessarily so, since it supports an independent function—self-management. Given the fact that unlike a computer, the brain must, of necessity, operate itself, it needs to be in touch with itself to do so. Intrinsic phenomenal forms of cognitive expression allow the brain to do just that by registering characteristics of the cognitive states themselves. Self-management might well prove to constitute the prime reason for the emergence of subjectivity itself. (shrink)

Definitions of phenomenal types (Nelson Goodman’s definition of qualia, Sydney Shoemaker’s phenomenal types, Austen Clark’s physicalist theory of qualia) imply that numerically distinct experiences can be type-identical in some sense. However, Goodman also argues that objects cannot be replicated in respect of continuous and densely ordered types. In that case, how can phenomenal types be defined for sizes, shapes and colours, which appear to be continuously ordered types? Concentrating on size, I will argue for the following points. (...) (§2) We cannot deny the possibility of replication in respect of dense types, because this would imply that particulars have determinable sizes, shapes and colours. (§3) Phenomenal sizes and shapes are determinable types; objective, or super-determinate, sizes and shapes are unknowable. (§4) We can define and know, prior to verification, groupings of objective sizes for which indiscriminability is transitive. (§5) Phenomenal identity has to be defined on the basis of these transitive groupings, because finer-grained criteria (such as Goodman’s) lead to definition of objective identity. The quality space of phenomenal types consists of overlapping but not dense types, and this prevents a collapse of phenomenal types. (shrink)
