This paper shows why qualia constitute a problem for any theory of mental phenomena. We use the term ‘qualia’ in reference to non-intentional features of mental states which are eminently qualitative, i.e. perceptions, emotions, moods and body sensations. These non-intentional features are usually described as intrinsic, ineffable, infallible, atomic, private, direct and irreducible to the physical. The paper also explains the absent qualia argument which is addressed as a critique to functionalism.

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)

According to Tye's PANIC theory of consciousness, perceptual states of creatures which are related to a disjunction of external contents will fail to represent sensorily, and thereby fail to be conscious states. In this paper I argue that heat perception, a form of perception neglected in the recent literature, serves as a counterexample to Tye's radical externalist claim. Having laid out Tye's absent qualia scenario, the PANIC theory from which it derives and the case of heat perception as (...) a counterexample, I defend the putative counterexample against three possible responses: (1) that heat perception represents general (i.e. non-disjunctive) intrinsic properties of objects, (2) that heat perception represents the non-specific heat energy that is transferred between a subject's body and another body and (3) that heat perception exclusively represents heat properties of the subjects own body.

I develop several new arguments against claims about "cognitive phenomenology" and its alleged role in grounding thought content. My arguments concern "absent cognitive qualia cases", "altered cognitive qualia cases", and "disembodied cognitive qualia cases". However, at the end, I sketch a positive theory of the role of phenomenology in grounding content, drawing on David Lewis's work on intentionality. I suggest that within Lewis's theory the subject's total evidence plays the central role in fixing mental content and (...) ruling out deviant interpretations. However I point out a huge unnoticed problem, the problem of evidence: Lewis really has no theory of sensory content and hence no theory of what fixes evidence. I suggest a way of plugging this hole in Lewis's theory. On the resulting theory, which I call " phenomenal functionalism", there is a sense in which sensory phenomenology is the source of all determinate intentionality. Phenomenal functionalism has similarities to the theories of Chalmers and Schwitzgebel. (shrink)

Often, sensory input underdetermines perception. One such example is the perception of illusory contours. In illusory contour perception, the content of the percept includes the presence of a contour that is absent from the informational content of the sensation. (By “sensation” I mean merely information-bearing events at the transducer level. I intend no further commitment such as the identification of sensations with qualia.) I call instances of perception underdetermined by sensation “underdetermined perception.” The perception of illusory contours is (...) just one kind of underdetermined perception. The focus of this chapter is another kind of underdetermined perception: what I shall call "active perception". Active perception occurs in cases in which the percept, while underdetermined by sensation, is determined by a combination of sensation and action. The phenomenon of active perception has been used by several to argue against the positing of representations in explanations of sensory experience, either by arguing that no representations need be posited or that far fewer than previously thought need be posited. Such views include, but are not limited to those of Gibson (1966, 1986), Churchland. (shrink)

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.

According to representionalists, qualia-the introspectible properties of sensory experience-are exhausted by the representational contents of experience. Representationalists typically advocate an informational psychosemantics whereby a brain state represents one of its causal antecedents in evolutionarily determined optimal circumstances. I argue that such a psychosemantics may not apply to certain aspects of our experience, namely, our experience of space in vision, hearing, and touch. I offer that these cases can be handled by supplementing informational psychosemantics with a procedural psychosemantics whereby a (...) representation is about its effects instead of its causes. I discuss conceptual and empirical points that favor a procedural representationalism for our experience of space. (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)

The claim that behaviourally undetectable inverted spectra are possible has been endorsed by many physicalists. I explain why this starting point rules out standard forms of scientific explanation for qualia. The modern ‘phenomenal concept strategy’ is an updated way of defending problematic intuitions like these, but I show that it cannot help to recover standard scientific explanation. I argue that Chalmers is right: we should accept the falsity of physicalism if we accept this problematic starting point. I further argue (...) that accepting this starting point amounts to at least implicitly endorsing certain theoretical claims about the nature of introspection. I therefore suggest that we allow ourselves to be guided, in our quest to understand qualia, by whatever independently plausible theories of introspection we have. I propose that we adopt a more moderate definition of qualia, as those introspectible properties which cannot be fully specified simply by specifying the non-controversially introspectible ‘propositional attitude’ mental states (including seeing x, experiencing x, and so on, where x is a specification of a potentially public state of affairs). Qualia thus defined may well fit plausible, naturalisable accounts of introspection. If so, such accounts have the potential to explain, rather than explain away, the problematic intuitions discussed earlier; an approach that should allow integration of our understanding of qualia with the rest of science. (shrink)

Whether or not qualia are ways things seem, the view that qualia have the properties typically attributed to them is unjustified. Ways things seem do not have many of the properties commonly attributed to them. For example, inverted ways things seem are impossible. If ways things seem do not have the features commonly attributed to them, and qualia do have those same features, this looks like good reason to distinguish the two. But if your reasons for believing (...) that qualia have the features are epistemically on a par with reasons for believing that ways things seem have the features, and you know that ways things seem do not have the features, then those reasons cannot justify your belief that qualia have the features. I argue that the reasons are epistemically on a par in this way. (shrink)

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)

Qualia are defined as subjective or private feelings associated with sensory and other experiences. This article argues that private feelings might be expressed by or in a personal brain and discusses possible neurobiological implications. Four issues are considered: Functional dualism implies that mental functions are realized as emergent properties of the brain. In practice, functional dualism is compatible with both substance dualism and pan-psychism. The (adult) human brain is the product of biological and environmental processes, including cultural influences, and (...) is individually unique. Part of the cerebral neuronal processing is molded by individual memories and previous experiences. Biological processes underlying the realization of qualia, including neural activities, escape conscious control. The temporal expression of qualia is in part consciously channeled by, for instance, actual situations and cultural habits. Neuroscientific explanations refer to general principles of nature, rather than to individual phenomena. Hence, future neurobiological approaches might aim to identify which neuronal processes are involved in qualia and how. It seems illusory to explain each quale. (shrink)

In this paper we advocate the thesis that qualia are tropes (or qualitons), and not (universal) properties. The main advantage of the thesis is that we can accept both the Wittgensteinian and Sellarsian assault on the given and the claim that only subjective and private states can do justice to the qualitative character of experience. We hint that if we take qualia to be tropes, we dissolve the problem of inverted qualia. We develop an account of sensory (...) concept acquisition that takes the presence of qualia as an enabling condition for learning. We argue that qualia taken to be qualitons are part of our mechanism of sensory concept acquisition. (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.

Many so-called problems in contemporary philosophy of mind depend for their expression on a collection of inter-defined technical terms, a few of which are qualia, phenomenal property, and what-it’s-like-ness. I express my scepticism about Keith Frankish’s illusionism, the view that people are generally subject to a systematic illusion that any properties are phenomenal, and scout the relative merits of two alternatives to Frankish’s illusionism. The first is phenomenal meta-illusionism, the view that illusionists such as Frankish, in holding their view, (...) are themselves thereby under an illusion. The second is qualia quietism, the view that nothing worth saying is said by employing any of the aforementioned inter-defined technical terms. (shrink)

How does one know the phenomenal character of one’s own experience? I aim to present and defend a new view of the epistemology of qualia that addresses this issue. My view results from a reworking of Dretske’s displaced perception model. The guiding line is the key Wittgensteinian insight of his Private Language Argument, namely the claim that no inner perception of qualia can justify our corresponding qualia-beliefs. My reworking of the original model starts with the rejection of (...) Dretske’s representationalism, as well as any other metaphysical views about the ultimate nature of qualia. The reworking of the displaced perception model I am proposing is supposed to be compatible with any available meta- physical view on qualia. The second step consists of rejecting the epistemological misgivings of the original model, namely the view that knowing qualia requires “connecting beliefs” along with “meta-representations.” Yet, Dretske’s crucial mistake has been to force knowledge of qualia into the “belief-box.” As a matter of fact, there is only one belief involved in intro- specting qualia, namely the qualia-belief itself. The third final step is this. Assuming the key Wittgensteinian insight, I argue that introspection of qualia is a process that is both epis- temically reliable and automatic. It is reliable because it dispenses with justification of any beliefs whatsoever. Moreover, it is automatic because it also dispenses with reflexive con- necting beliefs. For example, it takes nonconceptual awareness of the color blue as an input and automatically yields the belief that phenomenal blue is the conscious character of my experience of the sky as an output just by employing the concept BLUE. (shrink)

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)

Computationalism treats minds as computations. It hasn't explained how our quite similar sensory circuits encode our quite different qualia, nor how these circuits encode the binding of the different qualia into unifi ed perceptions. But there is growing evidence that qualia and binding come from neural electrochemical substances such as sensory detectors and the strong continuous electromagnetic field they create. Qualia may thus be neural substances, not neural computations (though computations may still help modulate qualia). (...) This neuroelectrical view not only avoids computationalism's empirical issues but also its problematic metaphysics. (shrink)

Neurological syndromes in which consciousness seems to malfunction, such as temporal lobe epilepsy, visual scotomas, Charles Bonnet syndrome, and synesthesia offer valuable clues about the normal functions of consciousness and ‘qualia’. An investigation into these syndromes reveals, we argue, that qualia are different from other brain states in that they possess three functional characteristics, which we state in the form of ‘three laws of qualia’. First, they are irrevocable: I cannot simply decide to start seeing the sunset (...) as green, or feel pain as if it were an itch; second, qualia do not always produce the same behaviour: given a set of qualia, we can choose from a potentially infinite set of possible behaviours to execute; and third, qualia endure in short-term memory, as opposed to non-conscious brain states involved in the on-line guidance of behaviour in real time. We suggest that qualia have evolved these and other attributes because of their role in facilitating non-automatic, decision-based action. We also suggest that the apparent epistemic barrier to knowing what qualia another person is experiencing can be overcome by using a ‘bridge’ of neurons; and we offer a hypothesis about the relation between qualia and one's sense of self. (shrink)

Experiences of motion and change are widely taken to have a ‘flow-like’ quality. Call this ‘temporal qualia’. Temporal qualia are commonly thought to be central to the question of whether time objectively passes: (1) passage realists take temporal passage to be necessary in order for us to have the temporal qualia we do; (2) passage antirealists typically concede that time appears to pass, as though our temporal qualia falsely represent time as passing. I reject both claims (...) and make the case that passage-talk plays no useful explanatory role with respect to temporal qualia, but rather obfuscates what the philosophical problem of temporal qualia is. I offer a ‘reductionist’ account of temporal qualia that makes no reference to the concept of passage and argue that it is well motivated by empirical studies in motion perception. (shrink)

When reasoning about dependence relations, philosophers often rely on gradualist assumptions, according to which abrupt changes in a phenomenon of interest can only result from abrupt changes in the low-level phenomena on which it depends. These assumptions, while strictly correct if the dependence relation in question can be expressed by continuous dynamical equations, should be handled with care: very often the descriptively relevant property of a dynamical system connecting high- and low-level phenomena is not its instantaneous behavior, but its stable (...) fixed points (those in the vicinity of which it spends most of the time, after comparatively short transitory periods), and stable fixed points can change abruptly as a result of infinitesimal changes of the low-level phenomenon. We illustrate this potential gradualist trap by showing that Chalmers’s fading qualia argument falls in it. (shrink)

The claim that consciousness is propositional has be widely debated in the past. For instance, it has been discussed whether consciousness is always propositional, whether all propositional consciousness is linguistic, whether propositional consciousness is always articulated, or whether there can be non-articulated propositions. In contrast, the question of whether propositions are conscious has not very often been the focus of attention.

First, I briefly characterize Dretske’s particular naturalization project, emphasizing his naturalistic reconstruction of the notion of representation. Second, I note some apparent similarities between his notion of representation and Husserl’s notion of intentionality, but I find even more important differences. Whereas Husserl takes intentionality to be an intrinsic, phenomenological feature of thought and experience, Dretske advocates an “externalist” account of mental representation. Third, I consider Dretske’s treatment of qualia, because he takes it to show that his representational account of (...) mind succeeds in naturalizing even the “subjective” features of experience. I claim that Dretske's argument for his account of qualia turns on an ambiguous characterization of qualia. I conclude that he succeeds in naturalizing qualia only if qualia are understood as nonphenomenological features of experience and that he therefore has less to say than he thinks about the subjective life of beings such as us.

Daniel Dennett provides many compelling reasons to question the existence of phenomenal experiences in his paper titled Quining Qualia, however, from the perspective of the individual, qualia appear to be an inherent feature of consciousness. The act of reflecting on one’s experiences suggests that subjective feelings and sensations are a necessary element of human life, as personal opinions on various artistic works are apt to demonstrate. This paper argues that by considering subjective experiences from a naturalized functionalist perspective, (...) a comprehensive explanation for qualia can be provided given its origins in evolutionary biology. As information passing through the nervous system, qualia serve to guide the behaviour of individuals to ultimately facilitate survival. Specifically, qualia are representations of environmental features, existing as information messages supported by neural physiology and encoded in electrochemical formats. In addition to addressing the Hard Problem of Consciousness and clarifying the four properties Dennett associates with qualia, this theoretical foundation enables further metaphysical discussion on the nature of consciousness more generally. Although many outstanding questions on the contents of subjective experiences are apt to linger given the explanatory gap, a robust theory for the existence of qualia can be developed through the integration of ideas and concepts from a variety of domains.

The mind-body problem in contemporary philosophy has two parts: the problem of mental causation and the problem of consciousness. These two parts are not unrelated; in fact, it can be helpful to see them as two horns of a dilemma. On the one hand, the causal interaction between mental and physical phenomena seems to require that all causally efficacious mental phenomena are physical; but on the other hand, the phenomenon of consciousness seems to entail that not all mental phenomena are (...) physical.2 One may avoid this dilemma by adopting an epiphenomenalist view of consciousness, of course; but there is little independent reason for believing such a view. Rejecting epiphenomenalism, then, leaves contemporary philosophers with their problem: mental causation inclines them towards physicalism, while consciousness inclines them towards dualism. (shrink)

Despite recent breakthroughs in the field of artificial intelligence (AI) – or more specifically machine learning (ML) algorithms for object recognition and natural language processing – it seems to be the majority view that current AI approaches are still no real match for natural intelligence (NI). More importantly, philosophers have collected a long catalogue of features which imply that NI works differently from current AI not only in a gradual sense, but in a more substantial way: NI is closely related (...) to consciousness, intentionality and experiential features like qualia (the subjective contents of mental states)1 and allows for understanding (e.g., taking insight into causal relationships instead of ‘blindly’ relying on correlations), as well as aesthetical and ethical judgement beyond what we can put into (explicit or data-induced implicit) rules to program machines with. Additionally, Psychologists find NI to range from unconscious psychological processes to focused information processing, and from embodied and implicit cognition to ‘true’ agency and creativity. NI thus seems to transcend any neurobiological functionalism by operating on ‘bits of meaning’ instead of information in the sense of data, quite unlike both the ‘good old fashioned’, symbolic AI of the past, as well as the current wave of deep neural network based, ‘sub-symbolic’ AI, which both share the idea of thinking as (only) information processing: In symbolic AI, the name explicitly references to its formal system based, i.e. essentially rule-based, nature, but also sub-symbolic AI is (implicitly) rule-based, only now via globally parametrized, nested functions. In the following I propose an alternative view of NI as information processing plus ‘bundle pushing’, discuss an example which illustrates how bundle pushing can cut information processing short,and suggest first ideas for scientific experiments in neuro-biology and information theory as further investigations.

Scientific realists argue that a good track record of multi-agent, and multiple method, validation of empirical claims is itself evidence that those claims, at least partially and approximately, reflect ways nature actually is independent of the ways we conceptualize it. Constructivists contend that successes in validating empirical claims only suffice to establish that our ways of modelling the world, our “constructions,” are useful and adequate for beings like us. This essay presents a thought experiment in which beings like us intersubjectively (...) validate claims about properties of particular things in nature under conditions in which those beings have profoundly different personal phenomenological experiences of those properties. I submit that the thought experiment scenario parallels our actual situation, and argue that this shows that successes in intersubjectively validating empirical claims are indeed enough to claim victory for the realist. More specifically, I champion a variation of realism that marries Ronald Giere’s brand of ‘perspectival realism’ with Philip Kitcher’s ‘real realism,’ and posits that causal relations between ourselves and properties instantiated in nature ground our references to the relevant properties even though our conceptions of them are perspective relative.

The hard problem – focusing essentially on vision here – is in fact the problem of the origin of our image of the external world. This formulation in terms of the “image” is never seen stated, for the forms populating our image of the world are considered computable, and not considered qualia – the “redness” of the cube is the problem, not the cube as form. Form, however, cannot be divorced from motion and hence from time. Therefore we must (...) examine the classical, spatial metaphysic of space and time, for practical purposes initiated by Galileo, wherein the real has been equated with the quantitative and wherein quality has been stripped from the material world. In this metaphysic, which sees form as quantitative or computable, the origin of qualia is problematic, with a problem of even greater primacy becoming the “memory” that supports the transforming events of perception, e.g., rotating cubes, buzzing flies, twisting leaves. It is this memory, supporting time-extended, flowing events, that necessarily supports all qualia. The concept of storage of “snapshots” of time-flowing events, a notion which the classic metaphysic engenders, is unworkable as a solution to the perception of these flows. Form, in fact being dynamic and defined over flowing fields, equally is a quality, equally requires this memory, and since forms populate the image, the origin of the entire image is indeed a problem. The counter-proposal becomes Bergson’s temporal metaphysic wherein motion is indivisible (or non-differentiable), the global motion of the universal field itself then carrying an intrinsic form of memory. In this framework, with this field viewed as holographic, Bergson provides a unique solution – one that leaves the problem of representation behind – as to how the brain specifies the qualitative image of the dynamically transforming external world.

Discussions of psychiatric nosology focus on a few popular examples of disorders, and on the validity of diagnostic criteria. Looking at Anorexia Nervosa, an example rarely mentioned in this literature, reveals a new problem: the DSM has a strict taxonomic structure, which assumes that disorders can only be located on one branch. This taxonomic assumption fails to fit the domain of psychopathology, resulting in obfuscation of cross-category connections. Poor outcomes for treatment of Anorexia may be due to it being pigeonholed (...) as an Eating Disorder, when a disturbance of body perception may be a more central symptom than food restriction. This paper explores the possibility of restructuring the DSM taxonomy to allow for a pluralist classification of disorders. This change could improve treatment and research without requiring any changes to diagnostic criteria. (shrink)

The Absent World is an essay about the operation of language and thought concerning the gap between sense and referent. Due to variations in the structure of this gap, when we speak or think about the absent world, without the present object to supplement our meaning, unique psychological and ethical dimensions arise as we try to understand a world that surpasses us. As opposed to phenomenology, where the concept of absence structures our understanding of the absent world, (...) this work will posit the actuality of the absent as the basis of another relationship between ourselves and a world that is unseen. This thought of actuality will be developed through an exploration of empathy and a particular thought of death. Then it will be shown how it provides an aspect of a re-imagined concept of depth which, as it refers to a world that overflows any generality, will manipulate the gap between sense and referent in such a way that the usually silent operations of generalisation become not only manifest but pushed towards new extremes. This conceptual movement will be shown to be operative in our understanding of the absent, altering the way a subject’s world can be transformed by its interaction with the unknowns that surpass it.

Many believe that a suitably programmed computer could act for its own goals and experience feelings. I challenge this view and argue that agency, mental causation and qualia are all founded in the unique, homeostatic nature of living matter. The theory was formulated for coherence with the concept of an agent, neuroscientific data and laws of physics. By this method, I infer that a successful action is homeostatic for its agent and can be caused by a feeling - which (...) does not motivate as a force, but as a control signal. From brain research and the locality principle of physics, I surmise that qualia are a fundamental, biological form of energy generated in specialized neurons. Subjectivity is explained as thermodynamically necessary on the supposition that, by converting action potentials to feelings, the neural cells avert damage from the electrochemical pulses. In exchange for this entropic benefit, phenomenal energy is spent as and where it is produced - which precludes the objective observation of qualia. (shrink)

In this paper I explore the logical relationship between the question of the reality of qualia and the problem of universals. I argue that nominalism is inconsistent with the existence of qualia, and that realism either implies or makes plausible the existence of qualia. Thus, one's position on the existence of qualia is strongly constrained by one's answer to the problem of universals.

C. S. Peirce is often credited as a forerunner of the verificationist theory of meaning. In his early pragmatist papers, Peirce did say that if we want to make our ideas clear(er), then we should look downstream to their actual and future effects. For many who work in philosophy of mind, this is enough to endorse functionalism and dismiss the whole topic of qualia. It complexifies matters, however, to consider that the term qualia was introduced by the founder (...) of pragmatism himself. Peirce was adamant that only triadic relations can support language and cognition. Even so, he insisted on purely logical grounds that, when we analyze triadic signs all the way, we are left with a qualitative residue he called Firstness. Such an isolated relatum could never be studied experimentally. Yet, given that this primitive state can be confirmed by means of a formal or prescissive distinction, I believe the Peircean account can do justice to many of the intuitions that generate the so-called hard problem of consciousness. My goal, then, is to show that Peirce's semiotic commitment to qualia is compatible with his foundational statements about pragmatism. (shrink)

Abstract to Equations, Qualia, and Qualations -/- With regard to consciousness, we could write an equation B = black. But it is possible to rewrite this using a quale, namely, B = █. This latter equation might be called a ‘qualation’. It has the same meaning regardless of the physiology that apprehends it. This article argues a whole theory of qualations could be developed. Further, to a Dualist, it could be that a materialist is convinced by materialist arguments involving (...) the first equation, but it is unimaginable how this could ever be for a qualation. In view of the strong association of qualia with McTaggart’s A-series (future/present/past) a few notes on time are included. (shrink)

Computational neuroscience attributes coloured areas and other perceptual qualia to calculations that are realizable in multiple cellular forms. This faces serious issues in explaining how the various qualia arise and how they bind to form overall perceptions. Qualia may instead be neuroelectrical. Growing evidence indicates that perceptions correlate with neuroelectrical activity spotted by locally activated EEGs, the different qualia correlate with the different electrochemistries of unique detector cells, a unified neural-electromagnetic field binds this activity to form (...) overall perceptions, and this field interacts with sensory circuits to help attentively guide perception. The coloured areas in images may thus be seated in the electrochemistry of unique cells, while constancy mechanisms and other multiply realizable computations just help refine these images behind the scenes. This theory is ultimately testable. (shrink)

Things strike me in a variety ways. F and F# sound slightly different, ripe and unripe tomatoes neither look nor taste nor smell the same, and silk feels smoother than corduroy. In each case, I distinguish an experience of something on the basis of what it is like to be its subject. That is to say, in philosophical parlance, if not quite the vernacular, its “quale,” leads me to categorize it and, thus, respond appropriately to its stimulus. The function of (...) a quale being established, we must define it along with its subject and, as Sartre maintained, their relation. How should we understand the subject and predicate terms and the copula in sentences such as ‘He is listening to Chopin’ or ‘She is seeing the sights of Paris’? Elaborating upon adverbialism, I shall argue that the subject of experiencing is a hylomorphic compound that is temporarily identical to the 'accidental compound' that it forms along with a qualified passion. I begin by explicating the adverbialist’s treatment of qualitative consciousness and defending it against the charge of circularity. (shrink)

The logic of qualia is different than classical logic. We take the first steps in defining it and applying it to the Hard Problem.

The world provides us with an ocean of opportunities for fitting emotion. But we are beings with limited emotional resources, so missed opportunities are common. This chapter argues that these failures to take up fitting emotions are very frequently unfitting in their own right—so frequently, in fact, that most of us lead lives replete with unfitting absences of emotion. It begins by showing that, whenever an emotion can be unfitting in virtue of being too weak, the absence of that emotion (...) can also be unfitting, and for just the same reason. But emotional responses to a host of everyday objects—a funny joke, a nasty insult, and so on—can be unfittingly weak. This means that failures to respond emotionally to an enormous host of everyday objects are similarly unfitting. (shrink)

Why is there something rather than nothing? I don’t know. But ‘nothing’ may not be the correct default state. It may be that the existence of possibilities requires fewer (weaker) assumptions. In this case, arguably, we should start with the existence of possibilities and not ‘nothing’. In this case, there exists the possibility of (for example) red qualia. But the possible existence of a red quale does not delineate what it is the possibility of if the possibility contains only (...) a reference to red. Instead, the possibility must contain an actual instance of red to delineate what it is the possibility of. But, if possibilities are the weakest and (therefore) starting assumption, and the possibility of a red quale must itself contain an instance of red, then red exists necessarily. This argument would work for all qualia. Further, it could be that physical things and physical laws are (in some sense) instances of qualia. Incidentally, this would solve the problem of evil: pain, too, is made of qualia. These considerations align with some suggestions by Leibniz. (shrink)

Why is there something rather than nothing? I don't know. But I give an argument that qualia exist *necessarily*. The *possibility* of the existence of red qualia requires actual red qualia to specify what the possibility is a possibility *of*.

This paper distinguishes two types of qualia theory, which I call Galilean and non-Galilean qualia theories. It also offers considerations against each type of theory. To my mind the considerations are powerful. In any case, they bring out the importance of distinguishing the two types of theory. For they show that different considerations come into play—or considerations come into play in quite different ways—in assessing the two types of theory.

The Presocratic philosopher Heraclitus quoted an ancient Greek proverb, “Absent while present.” This paper argues that social technology, which makes us present to those absent, also makes us absent to those present. That is, technology connects our attentions to our virtual community of friends but in doing so it disconnects our attentions from those about us. Because we are finite beings, who dwell wherever our attentions reside, there is a real conflict between the connectivity of social technology (...) and bodily communion with those about us. The interpersonal presence afforded by social technology is a presence purchased at a price: the absence of the body. What social technology is incapable of achieving is bodily presence, and bodily presence is needed for intimacy and friendship. (shrink)

Researching into our past, scientists use different methods, from looking at the night sky to digging traces of our past and analyzing DNA. I propose here another method, that can have the potential of shedding more light into our history and the type of entities that we are. Working under philosophical idealism, I propose that evolution is in the first place the evolution of consciousness, and thus the traces of evolution are mostly not to be found in our physical bodies, (...) but in our consciousnesses. I argue that qualia are selected by evolution in order to solve evolutionary problems, and thus, looking into our qualia we can learn about our evolutionary history. (shrink)

This is a paper about a general representational theory of consciousness. It is quite old, and much progress has been made since. We are building and tracking consensus arround the ideas in the Representational Qualia Theory camp on Canonizer.

In this paper we put forward the thesis that qualia are tropes (or qualitons), and not (universal) properties. Further, we maintain that Wittgenstein hints in this direction. We also find in Wittgenstein elements of an account of language acquisition that takes the presence of qualia as an enabling condition. We conclude by pointing out some difficulties of this view.

This article argues that standard causal and functionalist definitions of realization fail to account for the realization of entities that cannot be individuated in causal or functional terms. By modifying such definitions to require that realizers also logically suffice for any historical properties of the entities they realize, one can provide for the realization of entities whose resistance to causal/functional individuation stems from their possession of individuative historical properties. But if qualia cannot be causally or functionally individuated, then (...) class='Hi'>qualia can be physically realized only if the thesis that all things are physical or physically realized is insufficient for physicalism.

Applying Michel Henry’s philosophical framework to the phenomenological analysis of religious experience, the author introduces a concept of material introspection and a new theory of the constitution of religious experience in phenomenologically material interiority. As opposed to ordinary mental self-scrutiny, material introspection happens when the usual outgoing attention is reverted onto embodied self-awareness in search of mystical self-knowledge or union with God. Such reversal posits the internal field of consciousness with the self-disclosure of phenomenological materiality. As shown by the example (...) of Vedantic self-inquiry, material introspection is conditioned on the attitude ‘I “see” myself’ and employs reductions which relieve phenomenological materiality from the structuring influence of intentionality; the telos of material introspection is expressed by the inward self-transcendence of intentional consciousness into purified phenomenological materiality. Experience in material introspection is constituted by the self-affection and self-luminosity of phenomenological materiality; experience is recognized as religious due to such essential properties as the capacity of being selffulfilled, and specific qualitative “what it’s like”(s). Drawing on more than 5000 live accounts of internal religious experience, it is shown that introspective attention can have different trajectories, producing, within a temporal extension of material introspection, different spatial modifications of embodied selfawareness and a variety of corresponding religious experiences.

For Heidegger, the fundamental “rationality” of Western metaphysics lies in the fact that its “leading question” concerning beings as beings constantly refers back to the question concerning the ground (arche, ratio, Grund) of beings. Whereas metaphysics has sought to ground beings in ideal beingness, Heidegger attempts to think beingness as itself based on the withdrawing “background” dimension of no-thing-ness that grounds finite presence by differing from it. In Heidegger’s earlier work, the structure of this “grounding” is considered in terms of (...) Dasein’s temporal transcendence; later, it is rearticulated through the fourfold dimensionality of meaningfulness (Geviert), converging in a concrete thing. (shrink)
