Antireductionist philosophers have argued for higher-order classifications of qualia that locate consciousness outside the scope of conventional scientific explanations, viz., by classifying qualia as intrinsic, basic, or subjective properties, antireductionists distinguish qualia from extrinsic, complex, and objective properties, and thereby distinguish conscious mental states from the possible explananda of functionalist or physicalist explanations. I argue that, in important respects, qualia are intrinsic, basic, and subjective properties of conscious mental states, and that, contrary to antireductionists' suggestions, these (...) higher-order classifications are compatible with qualia reduction. I demonstrate this compatibility by examining the putative higher-order properties of qualia and comparing them to the higher-order properties characteristic of connectionist models of cognitive processes. I contend that the higher-order properties characteristic of connectionist networks approximate the putative higher-order properties of qualia sufficiently well to conclude that qualia reductionism can accommodate claims that qualia are intrinsic, basic, and subjective properties, and explain the motivating intuitions for those claims generated by inverted, absent, and alien qualia thought experiments. In this way I argue that the putative higher-order classifications of qualia not only fail to defeat qualia reduction but, ironically, turn out to support it. (shrink)

What is the difference between the discriminations made by a home appliance able to distinguish salt from sugar, and my sensations of salty and sweet? It is never taken into consideration that, in contrast to the appliance, I can have offline sensations, i.e., phenomenal experiences in the absence of direct environmental stimuli, mainly evoked by words occurring into thought, conversation, reading, etc. If we put this detachment stimuli/sensations in relation with the correlative detachment signs/referents inaugurated by the cognitive revolution of (...) symbolic language , we might rethink the role played by language in our phenomenal experience as a whole. Qualia can be defined as forms of relationship between organisms and environment, given that human environment is extended to the linguistic dimension, and that the latter has ignited a coevolutionary process with human cognition. The very same properties we attribute to qualia, even when conceiving of them as pre-linguistic phenomenal traits, rely on the cognitive resources that language has made available. The substantialist notion of qualia, I argue, is formed by an online sensation on which the focus shifts from the perceived object to the sensory quality by virtue of linguistic modes of thinking, which are systematically neglected.

The exact relationship between qualia and the function of the brain remains elusive. The present approach focuses on the linkage between the neural mechanisms of the brain and the phenomenological and epistemological mechanisms of qualia. It is hypothesized that distinct characteristics of the ventral prefrontal cortical function may be crucial for the generation of these phenomenological and epistemological mechanisms this is reflected in the so-called 'neurophenomenological hypothesis'. The 'phenomenological—qualitative' character of qualia may be related with an early (...) activation in the ventromedial prefrontal cortex . The experience of 'presence' in qualia may be accounted for by a co-activation in both VMPFC and hippocampus and a concurrent deactivation in the ventrolateral prefrontal cortex and posterior cingulate. Past and future temporal dimensions may therefore be integrated within the experience of events, which in turn may account for the phenomenal characteristics of 'presence' and thus 'phenomenal time'. 'Non-structural homogeneity' in the experience of qualia may be accounted for by either 'supramodal character' or 'modality unspecifity' of >the VMPFC. The 'heterogenous' stimuli can therefore be included and integrated within one 'homogenous' event as experienced in qualia. Finally, 'transparency' in the experience of qualia may be related with the 'reciprocal suppression' between VMPFC and VLPFC. Simultaneous cognitive processing during the experience of qualia may be suppressed and may consequently account for their transparent character. Due to several methodological limitations, these 'neurophenomenological hypotheses' must be considered as preliminary. However, they may nevertheless serve as a starting point for the development of a more elaborate neuroscientific hypothesis of qualia in the future. (shrink)

Accounting for qualia in the natural world is a difficult business, and it is worth understanding why. A close examination of several theories of mind—Behaviorism, Identity Theory, Functionalism, and Integrated Information Theory—will be discussed, revealing shortcomings for these theories in explaining the contents of conscious experience: qualia. It will be argued that in order to overcome the main difficulty of these theories the senses should be interpreted as physical detectors. A new theory, Grounded Functionalism, will be proposed, which (...) retains multiple realizability while allowing for a scientifically based approach toward accounting for qualia in the natural world.

This paper argues that qualia share their physical correlates' locations. The first premise comes from the theory of relativity: If something shares a time with a physical event in all reference frames, it shares that physical event’s location. The second premise is that qualia share times with their correlates in all reference frames. Having qualia and correlates share locations makes relations between them easier to explain, improving both physicalist and dualist theories.

We define qualia space Q to be the space of all possible conscious experience. For simplicity we restrict ourselves to perceptual experience only, though other kinds of experience could also be considered. Qualia space is a highly idealized concept that unifies the perceptual experience of all possible brains. We argue that Q is a closed pointed cone in an infinite-dimensional separable real topological vector space. This quite technical structure can be explained for the most part in a simple, (...) intuitive way. The structure of qualia space allows us to consider and even answer in a precise way such questions as: Is there a continuous path from the sensation of blue to the sensation of pain? Once we fix a desired accuracy of approximation, do there exist finitely many perceptual experiences such that any possible perceptual experience is approximately equal to one of them? What should be meant by ‘fundamentally different’ perceptual experiences? There is the possibility of additional structure, such as a Hilbert space structure on the vector space in which Q is embedded. (shrink)

Qualia have proved difficult to integrate into a broadly physicalistic worldview. In this paper, I argue that despite popular wisdom in the philosophy of mind, qualia’s intrinsicality is not sufficient for their non-reducibility. Second, I diagnose why philosophers mistakenly focused on intrinsicality. I then proceed to argue that qualia are categorical and end with some reflections on how the conceptual territory looks when we keep our focus on categoricity.

The indirect realist theory of our knowledge of the external world which Russellian philosophers of mind have appealed to in formulating and defending a unique version of the mind-brain identity theory can be applied also to the formulation and defence of a unique version of functionalism. On the view that results, qualia turn out to be features which do not exist over and above the natural world , and are irreducibly subjective but are non-intrinsic properties of brain states . (...) This view, which can be called ‘Hayekian functionalism’ , thus shows how we can combine the best insights of functionalism with the respect for the subjectivity of qualia which critics of functionalism claim it cannot accommodate.

" Qualia " is an unfamiliar term for something that could not be more familiar to each of us: the ways things seem to us. As is so often the case with philosophical jargon, it is easier to give examples than to give a definition of the term. Look at a glass of milk at sunset; the way it looks to you--the particular, personal, subjective visual quality of the glass of milk is the quale of your visual experience at (...) the moment. The way the milk tastes to you then is another, gustatory quale, and how it sounds to you as you swallow is an auditory quale; These various "properties of conscious experience" are prime examples of qualia. Nothing, it seems, could you know more intimately than your own qualia ; let the entire universe be some vast illusion, some mere figment of Descartes' evil demon, and yet what the figment is made of will be the qualia of your hallucinatory experiences. Descartes claimed to doubt everything that could be doubted, but he never doubted that his conscious experiences had qualia, the properties by which he knew or apprehended them. (shrink)

Qualia internalism is the thesis that qualia are intrinsic to their subjects: the experiences of intrinsic duplicates have the same qualia. Content externalism is the thesis that mental representation is an extrinsic matter, partly depending on what happens outside the head. 1 Intentionalism comes in strong and weak forms. In its weakest formulation, it is the thesis that representationally identical experiences of subjects have the same qualia. 2.

This paper investigates the status of the purported explanatory gap between pain phenomena and natural science, when the “gap” is thought to exist due to the special properties of experience designated by “ qualia ” or “the pain quale” in the case of pain experiences. The paper questions the existence of such a property in the case of pain by: looking at the history of the conception of pain; raising questions from empirical research and theory in the psychology of (...) pain; considering evidence from the neurophysiological systems of pain; investigating the possible biological role or roles of pain; and considering methodological questions of the comparable status of the results of the sciences of pain in contrast to certain intuitions underpinning “the explanatory gap” in the case of pain. Skepticism concerning the crucial underlying intuitions seems justified by these considerations. (shrink)

Perception and thought are often, although not exclusively, concerned with information about the world. In the case of perceiving though, unlike thinking, it is widely believed that there is an additional element involved, a subjective feeling or, as it is often put, something that it is like to be perceiving. Qualia are these characteristic feelings that accompany perceiving. One motivation for the idea that we experience qualia is that there is a clear difference between seeing a red tomato (...) and thinking that a tomato is red and that the difference has to do with some extra element present in the case of seeing that is absent in the case of thinking. Philosophical attempts to understand qualia and their place in the world have played a central role in recent debates about the nature of mind and its place in the world. Before getting to those debates, we will take a more detailed look at the distinction between the content of perceptual experiences,what they tell us about the world, and their qualitative or phenomenal character, what it is like to experience them.

The qualia theory says that experiences’ phenomenal properties can come apart from and completely outrun their representational properties and that phenomenal properties are to be accounted for in terms of “qualia,” intrinsic nonrepresentational mental properties of experience. In Consciousness and Cognition Michael Thau argues that QT is incoherent. Thau’s argument fails. It rests on an illegitimate assimilation of phenomenal differences to differences in “the way things seem.” It begs the question by assuming that representational content can suffice for (...) phenomenal character. And it overlooks a crucial difference between two very different versions of QT. The upshot is that QT is much more plausible than representationalist critics like Thau have supposed. (shrink)

In this article, I give an original objection to Frank Jackson's argument for the conclusion that the subjective, felt properties of experience are causally inert. I show that the very act of asserting the existence of these properties undermines the claim that they are epiphenomenal. If this objection goes through, it is fatal to the argument in question.

According to Frank Jacksonʼs knowledge argument, Mary, who lives in a black-and-white world, has all the physical knowledge about the world, yet she has new information when she sees a red apple. If we accept this, then physicalism – according to which the description of the world can be realised entirely with the help of physical theories – is false. However, even if Jacksonʼs argument about new information is true, we do not have to discard physicalism. Even exclusively physical computer (...) systems are not capable of predicting their own sensory information if they are built using a specific structure and complexity. It can be shown that a specific type of computational system can lead to the creation of decision-related unpredictability of a specific type of sensory information. This investigation takes a charitable position towards the concept of qualia to provide it with a physicalist and computationalist explanation. (shrink)

In the field of machine consciousness, it has been argued that in order to build human-like conscious machines, we must first have a computational model of qualia. To this end, some have proposed a framework that supports qualia in machines by implementing a model with three computational areas (i.e., the subconceptual, conceptual, and linguistic areas). These abstract mechanisms purportedly enable the assessment of artificial qualia. However, several critics of the machine consciousness project dispute this possibility. For instance, (...) Searle, in his Chinese room objection, argues that however sophisticated a computational system is, it can never exhibit intentionality; thus, would also fail to exhibit consciousness or any of its varieties. This paper argues that the proposed architecture mentioned above answers the problem posed by Searle, at least in part. Specifically, it argues that we could reformulate Searle’s worries in the Chinese room in terms of the three-stage artificial qualia model. And by doing so, we could see that the person doing all the translations in the room could realize the three areas in the proposed framework. Consequently, this demonstrates the actualization of self-consciousness in machines. (shrink)

A thought experiment focuses attention on the kinds of commonalities and differences to be found in two small parts of visual cortical areas during responses to stimuli that are either identical in quality, but different in location, or identical in location and different only in the one visible property of colour. Reflection on this thought experiment leads to the view that patterns of neural activation are the best candidates for causes of qualitatively conscious events . This view faces a strong (...) objection, namely, that patterns can be realized in many media, and thus candidates for patterns that cause qualia might be realized in ways that would not plausibly result in consciousness. It is argued that this objection can be overcome if qualia-causing patterns of events must be realized within small spatial and temporal regions. Much more importantly, it is argued that this restriction on region size need not be ad hoc. The key concept needed to establish this important point is ‘natural salience’, i.e., distinction from background noise that does not depend on application of a criterion of selection. It is explained how natural salience could figure in an empirically-based theory that would entail size restrictions for qualia-causing neural activation patterns. The question is then raised as to how the resulting view diverges from Chalmers’ account, which relies on the Principle of Organizational Invariance. A second thought experiment envisages replacement of neurons by computer chips with synaptic interfaces. Reflection on this thought experiment enables us to conceptually, and possibly empirically, separate the two views. An argument for preferring the patterns- as-causes , or PACQ, view is given. Because natural salience does not plausibly produce strictly discontinuous boundaries between pattern and noise, questions naturally arise as to the relation of the PACQ view to panpsychism and to ‘emergence’. The PACQ view is distinguished from panpsychism, and it is explained how the former avoids what Seager calls ‘the combination problem', and is thus preferable to panpsychism. The relation of the PACQ view to ‘emergence’ is explained. The conclusion of the paper is that the PACQ view is a philosophically defensible and potentially scientifically fruitful view that offers qualia realists the best hypothesis concerning the neural causes of qualia.

This chapter focuses on the long‐term implications of exotic activities that can be experienced through Qualia Surfing: how they might seep into every nook and cranny of our culture, redefining what it means to be human. It produces a quick survey of different types and degrees of qualia surfing. Today, even the most utopian visions of the future contain a worm at their heart: the inevitable decline of humanity into a state of boredom and stagnation. The chapter discusses (...) the subject of abstract qualia because there are changes that could be made to uploaded brain that would give sensations of newness over and above simple sensory qualia. The most complete form of qualia surfing would involve a visit to a domain – a place where a group of people go to create some way of life or historical epoch, but with constraint that outside memories are checked at the door.

This paper revisits some classic thought experiments in which experiences are detached from their characteristic causal roles, and explores what these thought experiments tell us about qualia epiphenomenalism, i.e., the view that qualia are epiphenomenal properties. It argues that qualia epiphenomenalism is true just in case it is possible for experiences of the same type to have entirely different causal powers. This is done with the help of new conceptual tools regarding the concept of an epiphenomenal property. (...) One conclusion is that it is not obvious if qualia epiphenomenalism is false; and it is also not obvious what should make us believe that it is false—or for that matter, true. Connections between qualia epiphenomenalism, physicalism, and non-physicalist property dualism are further explored. (shrink)

In this paper I use thought-experiments to argue that functional organization fully determines conscious experience. These thought-experiments involve the gradual replacement of neurons by silicon chips, and similar scenarios. I argue that if "absent qualia" or "inverted qualia", are possible, then phenomena I call "fading qualia" and "dancing qualia" will be possible; but I argue that it is very implausible that fading or dancing qualia are possible. The resulting position is a sort of nonreductive functionalism.

Crooks has rightly pointed out that perceptions are unlike the external stimuli that trigger them, and that any discussion of "objective qualia" is likely to confuse or mislead. The important issue is whether the concept of objective qualia has been just unfortunate terminology and a bad example, or whether discarding the concept seriously harms the underlying position of mind-body identity. Neuroscience research to date has been fully consistent with some version of mind-brain monism, and is beginning to establish (...) which brain areas and types of brain activity are critical for conscious awareness. Nevertheless, it is uncertain how soon, if ever, research will answer the question of why consciousness and brain activity are linked. (shrink)

In this essay, I want to take another look at the phenomenon of transparency and its relevance to qualia realism and representationalism. I don’t suppose that what I have to say will cause those who disagree with me to change their minds, but I hope not only to clarify my position and that of others who are on my side of the debate but also to respond to various criticisms and objections that have arisen over the last 10–15 years (...) or so.The transparency thesisI begin with four quotations, two from G. E. Moore, one from Gilbert Harman, and one from an earlier paper of mine:…that which makes the sensation of blue a mental fact seems to escape us; it seems, if I may use a metaphor, to be transparent — we look through it and see nothing but the blue… (Moore 1903, p. 446).When we try to introspect the sensation of blue, all we can see is the blue: the other element is as if it were diaphanous (Moore 1903, p. 450).When Eloise sees a tree before her, the colors she experiences are all experien.

Experiences vary widely. For example, I run my fingers over sandpaper, smell a skunk, feel a sharp pain in my finger, seem to see bright purple, become extremely angry. In each of these cases, I am the subject of a mental state with a very distinctive subjective character. There is something it is _like_ for me to undergo each state, some phenomenology that it has. Philoso- phers often use the term 'qualia' to refer to the introspectively accessible properties of (...) experiences that characterize what it is like to have them. In this standard, broad sense of the term, it is very difficult to deny that there are qualia. There is another, more restricted use of the term. (shrink)

How does mind fit into nature? Philosophy has long been concerned with this question. No contemporary philosopher has done more to clarify it than Jaegwon Kim, a distinguished analytic philosopher specializing in metaphysics and philosophy of mind. With new contributions from an outstanding line-up of eminent scholars, this volume focuses on issues raised in Kim's work. The chapters cluster around two themes: first, exclusion, supervenience, and reduction, with attention to the causal exclusion argument for which Kim is widely celebrated; and (...) second, phenomenal consciousness and qualia, with attention to the prospects for a functionalist account of the mental. This volume is sure to become a major focus of attention and research in the disciplines of metaphysics and philosophy of mind. (shrink)

Sydney Shoemaker has reconciled a broadly functionalist and materialist conception of the mind with what he calls “the common-sense view‘ of the inverted spectrum. This paper explores Shoemaker’s articulation and defence of the common sense view, and the conception of the content of qualitative experience the lies behind it. It examines the Frege-Schlick view, and a counterargument that Shoemaker uses to raise a prima facie problem for the view he is defending. It is argued that when Shoemaker’s account of (...) class='Hi'>qualia is developed in response to the paradox, it loses its intuitive appeal and its claim on the label “common-sense view‘. (shrink)

What follows is a short thought experiment that aims to show, reductio ad absurdum, that narrow qualia internalism is probably inconsistent with a physicalist/functionalist theory of mind. Those wishing to rebut the argument presented here will need to demonstrate why spatial proximity and the right sort of causal connection of functionally isolated components are necessary to the instantiation of qualia.

In "Experience as a Way of Knowing" (this journal), the author tries to create some troubles for philosophers who believe in "qualia" or "what it is like". I think the author has underestimated the complexity of the issues, and I will voice my concerns in five sections. Besides presenting my interpretation of the author's position and challenging it, I will (1) challenge the author's treatment of the knowledge argument, especially the author's treatment of "this is what it is like (...) to see red", (2) challenge the author's interpretation of "what-it-is-like" talk and the author's view that phenomenal properties are theoretical postulates, (3) challenge the author's rejection of "apparent properties", and (4) point out some issues with the author's interpretation of several authors who write about the knowledge argument.

Qualia are phenomenal properties of sensations and perceptual states: they are whatever it is that gives such states their “felt,” qualitative character. (In speaking of sensations, I speak of course not of mental objects or mental contents, but of mental events—of sensings, not sensa.).

The aim of the paper is to defeat some standard anti-reductionist arguments concerning sensory qualia. Initially conditions on intertheoretic reduction in general are established. The standard arguments are then shown to presuppose a false conception of what reduction requires; or to commit a familiar intensional fallacy; or to be unsound; or to equivocate on crucial terms. An exploration of our making direct introspective contact with our neurophysiological states concludes the paper.

Despite such widespread acclaim, there are some influential theater critics who have panned Qualia!

In this paper, I propose that those who reject higher-order theories of consciousness should not rule out the possibility of having conscious experiences that they cannot introspect. I begin by offering four arguments that such non-introspectible conscious experiences are possible. Next, I offer two arguments for thinking that we actually have such experiences. According to the first argument, it is unlikely that evolution would have furnished us with a faculty of introspection that worked flawlessly. According to the second argument, there (...) are many plausible potential sources of non-introspectible experiences. Given that all of these sources are at least somewhat plausible, it is fairly probable that we have some kind or other. Finally, I consider whether we might be justified in believing that we can introspect all of our conscious experiences if in fact we can. I show that current approaches to justifying belief in epiphenomenal qualia do not carry over. The upshot of these arguments is that we should be less certain that we really know what it feels like to be us. There may be much more to our experiences than we are aware of. (shrink)

The paper examines the status of conscious presentation with regard to mental content and intentional states. I argue that conscious presentation of mental content should be viewed on the model of a secondary quality, as a subjectiveeffect of the microstructure of an underlying brain state. The brain state is in turn viewed as the instantiation of an abstract computational state, with the result that introspectively accessible content is interpreted as a presentation of the associated computational state realized by the brain. (...) However, if the relation between consciousness and representational content is construed in this manner, then conscious presentation does not provide an adequate foundation for the claim that human mental states areintrinsically intentional. On this model, I argue that functionalism is able to account for (non-intrinsic) intentionality, but not for consciousness, which has implications for the computational paradigm, as well as for Searle's Chinese room thought experiment.

By arguing that qualia is meaning or understanding, a new framework for understanding consciousness is developed. In this way, the meaning of yellow and red are uncovered. The suggested solutions are that yellow means “source of light” and red means “important”. Also, in the process of arguing that qualia is meaning, remarkable similarities in the structure of qualia are uncovered. In this way, a reason for why very hot and very cold water feel the same, is given. (...) The same behaviour is also shown to take place for colours. (shrink)

Color qualia inversion scenarios have played a key role in various philosophical debates. Most notably perhaps, they have figured in skeptical arguments for the fundamental unknowability of other persons’ color experiences. For these arguments to succeed, it must be assumed that a person's having inverted color qualia may go forever unnoticed. This assumption is now generally deemed to be implausible. The present paper defines a variant of color qualia inversion—termed ‘‘color qualia compression’’—and argues that the possibility (...) of undetectable color qualia compression is immune to the objections that have been levelled against color qualia inversion arguments, and that color qualia compression scenarios support full-blown skepticism regarding other people's color experiences.

Qualia are the elements of phenomenal consciousness -- the raw feels which constitute what it is like to be in a conscious mental state. Some claim that qualia are epiphenomenal properties -- mere by-products of brain function which are causally inert. Though this is an implausible theory, it is difficult to show that it is false. Here I present an ad hominem argument -- the argument from coincidence -- which shows that epiphenomenalism about qualia is explanatorily deficient (...) because it leaves unexplained a highly improbable state of affairs, and so we have good reason to suppose that qualitative properties must be causally efficacious, and must be so in virtue of their qualitative nature.

The problem of consciousness has become one of the biggest unsolved problem in philosophy from the last few decades. Qualia and intentionality are the two feature of consciousness. Qualia represents the conscious awareness, subjectivity or phenomenality whereas intentionality represents the understanding or object-directedness. These are the two major issues in the philosophy of mind while we address the problem of consciousness. The objective of this paper is to give an overview of these two features of consciousness namely intentionality (...) and qualia. Qualia is subjective in nature, whereas intentionality or object-directedness is objective in nature. This paper will focus on some major question regarding qualia and intentionality like, do qualia exist? What is the relationship between qualia and intentionality? Can qualia be reduced or to identify with intentionality or intentionality represent the qualia? Science by its nature objective whereas consciousness by its nature subjective so can there be a science of consciousness? And so on. My paper is divided into two parts, the first part will discuss the problem of qualia whereas the second part will focus on the intentionality and subjective-objective distinction both from the epistemological and ontological perspective.

If we are to preserve qualia, one possibility is to take the current academic, philosophical, and theoretical notion less seriously and current natural science and some pre-theoretical intuitions about qualia more seriously. Dennett (1997) is instrumental in showing how ideas of the intrinsicalness and privacy of qualia are misguided and those of ineffability and immediacy misinterpreted. However, by combining ideas of non-mechanicalness used in contemporary natural science with the pre-theoretical idea that qualia are special because they (...) are unique, we get a notion of qualia that is acceptable to naturalistic philosophy. The notion of unique qualia is not opposed to the idea that some of the characterizations of qualia have to be qualified. It is the folk-philosophical, academic, notions of theoreticity and conceptuality that have to be modified. (shrink)
