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.

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)

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.

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)

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.

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)

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)

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.

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)

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)

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)

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.

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)

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)

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.

Case studies in the psychophysics, modeling and localization of human vision are presented as an example of.

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.

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.

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.

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.

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)

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)

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)

According to phenomenal transparency, phenomenal concepts are transparent where a transparent concept is one that reveals the nature of that to which it refers. What is the connection between phenomenal transparency and our concept of a subject of experience? This paper focuses on a recent argument, due to Philip Goff, for thinking that phenomenal transparency entails transparency about subjecthood. The argument is premissed on the idea that subjecthood is related to specific phenomenal properties as (...) a determinable of more specific determinates. I argue that the argument fails, which opens the door for one to endorse phenomenal transparency while denying transparency about the concept of a subject of experience. I draw out the consequences of this for certain versions of the combination problem for panpsychist metaphysics and moreover argue that rejecting the transparency of subjecthood does not undermine anti-physicalist arguments premissed on considerations relating to phenomenal transparency.

Phenomenal socialism says that what we actually, directly, literally perceive is only or primarily instances of high-level phenomenal properties; this paper argues for phenomenal socialism in the weaker, primarily version. Phenomenal socialism is the philosophy of perception that goes with recognitionalism, which is the metaethics that goes with epiphanies. The first part states the recognitionalist manifesto. The second part situates this manifesto relative to some more global concerns, about naturalism, perception, the metaphysics of value, and (...) theory vs. anti-theory in ethics. The third part rehearses two familiar views about the possible contents of perceptual experience, Phenomenal Conservativism and Phenomenal Liberalism. It notes that the usual catalogue omits two other theoretical possibilities, Phenomenal Socialism and Phenomenal Nihilism, and it defends a watered-down form of Phenomenal Socialism from four main objections. The fourth part makes some connections with the epistemology of modality and with the role of the imagination. (shrink)

: Phenomenal knowledge usually comes from experience. But it need not. For example, one could know what it’s like to see red without seeing red—indeed, without having any color experiences. Daniel Dennett (2007) and Pete Mandik (forthcoming) argue that this and related considerations undermine the knowledge argument against physicalism. If they are right, then this is not only a problem for anti‐physicalists. Their argument threatens to undermine any version of phenomenal realism— the view that there are phenomenal (...) properties, or qualia, that are not conceptually reducible to physical or functional properties. I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. This will strengthen the case for physically and functionally irreducible qualia. 2 Phenomenal knowledge usually comes from experience. For example, I know what it’s like to see red because I have done so. Does knowing what it’s like to have an experience with phenomenal character X require having an experience with X? No. A famous counterexample is Hume’s missing shade of blue, in which one can extrapolate from phenomenally similar experiences (A Treatise of Human Nature, Bk. I, Pt. I, Sec. I).1 One might think that a weaker version of the no‐phenomenal‐knowledge‐without‐experience thesis remains tenable, e.g., that knowing what it’s like to see in color requires having or having had color experiences. But this thesis also seems doubtful. Peter Unger (1966) devised plausible counterexamples over four decades ago, and since then others (e.g., Lewis 1988, Alter 1998, Stoljar 2005) have done the same. One could have phenomenal knowledge of color experiences without having such experiences. Indeed, one could have such knowledge without having experiences that are remotely like color experiences. What is the significance of this observation for contemporary debates about consciousness and physicalism? Daniel Dennett (2007) and Pete Mandik (forthcoming) suggest that it undermines the knowledge argument against physicalism.2 That is because they take the claim that someone who has never seen in color could not know what it’s like to see in color to be the basis of the knowledge argument’s main epistemic premise: the premise that (roughly put) 3 no amount of physical knowledge is sufficient for phenomenal knowledge of color experiences. If they are right, then this is not only a problem for anti‐ physicalists. Many physicalists (e.g., Loar 1990/97, Papineau 2002, 2007) accept the knowledge argument’s epistemic premise. Dennett’s and Mandik’s arguments threaten all versions of what David Chalmers (2003) calls phenomenal realism, the view that there are phenomenal properties, or qualia, that are not conceptually reducible to physical or functional properties.3 I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. The net result will be to strengthen the case for physically inexplicable qualia. (shrink)

Frank Jackson’s famous Knowledge Argument moves from the premise that complete physical knowledge is not complete knowledge about experiences to the falsity of physicalism. In recent years, a consensus has emerged that the credibility of this and other well-known anti-physicalist arguments can be undermined by allowing that we possess a special category of concepts of experiences, phenomenal concepts, which are conceptually independent from physical/functional concepts. It is held by a large number of philosophers that since the conceptual independence of (...) phenomenal concepts does not imply the metaphysical independence of phenomenal properties, physicalism is safe. This paper distinguishes between two versions of this novel physicalist strategy –Phenomenal Concept Strategy (PCS) – depending on how it cashes out “conceptual independence,” and argues that neither helps the physicalist cause. A dilemma for PCS arises: cashing out “conceptual independence” in a way compatible with physicalism requires abandoning some manifest phenomenological intuitions, and cashing it out in a way compatible with those intuitions requires dropping physicalism. The upshot is that contra Brian Loar and others, one cannot “have it both ways.”. (shrink)

This paper explores the relationship between phenomenal properties and intentional properties. In recent years a number of philosophers have argued that intentional properties are sometimes necessitated by phenomenal properties, but have not explained why or how. Exceptions can be found in the work of Katalin Farkas and Farid Masrour, who develop versions of reductionism regarding phenomenally-necessitated intentionality (or "phenomenal intentionality"). I raise two objections to reductive theories of the sort they develop. Then I (...) propose a version of primitivism regarding phenomenal intentionality. I argue that primitivism avoids the pitfalls of reductionism while promising broad explanatory payoffs. (shrink)

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)

During the last two decades, several different anti-physicalist arguments based on an epistemic or conceptual gap between the phenomenal and the physical have been proposed. The most promising physicalist line of defense in the face of these arguments – the Phenomenal Concept Strategy – is based on the idea that these epistemic and conceptual gaps can be explained by appeal to the nature of phenomenal concepts rather than the nature of non-physical phenomenal properties. Phenomenal (...) concepts, on this proposal, involve unique cognitive mechanisms, but none that could not be fully physically implemented. David Chalmers has recently presented a Master Argument to show that the Phenomenal Concept Strategy – not just this or that version of it, but any version of it – fails. Chalmers argues that the phenomenal concepts posited by such theories are either not physicalistically explicable, or they cannot explain our epistemic situation with regard to qualia. I argue that it is his Master Argument that fails. My claim is his argument does not provide any new reasons to reject the Phenomenal Concept Strategy. I also argue that, although the Phenomenal Concept Strategy is successful in showing that the physicalist is not rationally compelled to give up physicalism in the light of the anti-physicalist arguments, the anti-physicalist is not rationally compelled to give up the anti-physicalist argument in the light of the Phenomenal Concept Strategy either.

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.

This paper defends a novel account of how we introspect phenomenal states, the Demonstrative Attention account (DA). First, I present a set of necessary and sufficient conditions for phenomenal state introspection which are not psychological, but purely metaphysical and semantic. Next, to explain how these conditions can be satisfied, I describe how demonstrative reference to a phenomenal content can be achieved through attention alone. This sort of introspective demonstration differs from perceptual demonstration in being non-causal. DA nicely (...) explains key intuitions about phenomenal self-knowledge, makes possible an appealing diagnosis of blindsight cases, and yields a highly plausible view as to the extent of our first-person epistemic privilege. Because these virtues stem from construing phenomenal properties as non-relational features of states, my defense of DA constitutes a challenge to relational construals of phenomenal properties, including functionalism and representationalism. And I provide reason to doubt that they can meet this challenge. (shrink)
