In this chapter, data concerning the development of principal aspects of vision is reviewed. First, the development of colour vision and luminance perception is discussed. Relevant data accumulated so far indicates that perception of colour and luminance is present by 6-9 months of age. The presence of typical color illusions at this age suggests that the phenomenal character of color experience is comparable to that of adults well before the first birthday. Thus it seems plausible that color perception develops (...) on the grounds of genetically preprogrammed maturation, in which perceptual learning and plasticity play a limited role. This claim also seems to be supported by case studies of newly sighted patients. On the other hand, perceptual integration of edges and forms in the visual environment as well as the development of binocular vision, and the perception of ambiguous figures seem to depend crucially on early perceptual learning. Both developmental and clinical data indicate a more significant involvement of perceptual learning in such mid-level and higher level perceptual phenomena. (shrink)

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

I discuss the apparent discrepancy between the qualitative diversity of consciousness and the relative qualitative homogeneity of the brain's basic constituents, a discrepancy that has been raised as a problem for identity theorists by Maxwell and Lockwood (as one element of the ‘grain problem’), and more recently as a problem for panpsychists (under the heading of ‘the palette problem’). The challenge posed to panpsychists by this discrepancy is to make sense of how a relatively small ‘palette’ of basic qualities could (...) give rise to the bewildering diversity of qualities we, and presumably other creatures, experience. I argue that panpsychists can meet this challenge, though it requires taking contentious stands on certain phenomenological questions, in particular on whether any familiar qualities are actual examples of ‘phenomenal blending’, and whether any other familiar qualities have a positive ‘phenomenologically simple character’. Moreover, it requires accepting an eventual theory most elements of which are in a certain explicable sense unimaginable, though not for that reason inconceivable. Nevertheless, I conclude that there are no conclusive reasons to reject such a theory, and so philosophers whose prior commitments motivate them to adopt it can do so without major theoretical cost.

The Quality of Thought develops and defends the thesis that thinking is a kind of experience, characterized by a sui generis (“cognitive”) phenomenology, determinates of which are thought contents—what I call the phenomenal intentionality of thought thesis. It draws out the implications of this thesis for issues in philosophy of mind, philosophy of language and metaphysics. The view defended is radically internalist and intensionalist, and thus goes against received doctrines in philosophy of mind (externalism) and language (extensionalism). It (...) also advocates for a metaphysically neutral, non-naturalistic approach to the philosophical study of mind—what I call “Analytic Phenomenology”—in combination with agnosticism about the nature of the relationship between consciousness and physical reality. -/- The book identifies persistent problems with Dretske-inspired causal-informational-teleological theories of conceptual content, and diagnoses them as due to leaving out what it’s like to think a thought—to entertain or grasp a propositional (conceptual) content. It is thus a contribution to the increasingly influential Phenomenal Intentionality Research Program. It includes refutations of classic externalism (Putnam and Burge) and arguments that standard motivations for direct reference theories of names (Kripke), indexicals and demonstratives (Kaplan) are not inevitable, and alternative accounts of their (and their conceptual equivalents’) semantics. It also addresses outstanding challenges to the phenomenal intentionalist view of thought content, including the existence of unconscious thought, the elusiveness of conceptual phenomenology, the matching content problem, phenomenal compositionality, and the determination of conceptual reference.

Pain is often used as the paradigmatic example of a phenomenal kind with a phenomenal quality common and unique to its instantiations. Philosophers have intensely discussed the relation between the subjective feeling, which unites pains and distinguishes them from other experiences, and the phenomenal properties of sensory, affective, and evaluative character along which pains typically vary. At the center of this discussion is the question whether the phenomenal properties prove necessary and/or sufficient for pain. In (...) the empirical literature, sensory, affective, and evaluative properties have played a decisive role in the investigation of psychophysical correspondence and clinical diagnostics. This paper addresses the outlined philosophical and empirical issues from a new perspective by constructing amultidimensional phenomenal spacefor pain. First, the paper will construe the phenomenal properties of pains in terms of a property space whosestructurereflects phenomenal similarities and dissimilarities by means of spatial distance. Second, philosophical debates on necessary and sufficient properties are reconsidered in terms of whether there is a phenomenal space formed of dimensions along which all and only pains vary. It is concluded that there is no space of this kind and, thus, that pain constitutes aprimitivephenomenal kind that cannot be analyzed entirely in terms of its varying phenomenal properties. Third, the paper addresses theutilityof continued reference to pain and its phenomenal properties in philosophical and scientific discourses. It is argued that numerous insights into the phenomenal structure of pain can be gained that have thus far received insufficient attention. (shrink)

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 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. (shrink)

I argue that phenomenal externalism is preferable to phenomenal internalism on the basis of externalism's explanatory power with respect to qualitative character. I argue that external qualities, namely, external physical properties that are qualitative independent of consciousness, are necessary to explain qualitative character, and that phenomenal externalism is best understood as accepting external qualities while phenomenal internalism is best understood as rejecting them. I build support for the claim that external qualities are necessary to explain qualitative (...) character on the basis of a model of color perception as a certain sort of information filter by which perceivers gain access to external qualities. (shrink)

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information-theoretic framework of Dretske (1981), we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so-called secondary qualities of objects. We show that these concepts have a special informational character and semantic structure (...) that closely tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal concepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspection. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory concepts, such as the concept of red. Contrary to widespread opinion, we show that information theory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and predicts the so-called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a substantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.

Conscious experiences are characterized by mental qualities, such as those involved in seeing red, feeling pain, or smelling cinnamon. The standard framework for modeling mental qualities represents them via points in geometrical spaces, where distances between points inversely correspond to degrees of phenomenal similarity. This paper argues that the standard framework is structurally inadequate and develops a new framework that is more powerful and flexible. The core problem for the standard framework is that it cannot capture precision structure: for (...) example, consider the phenomenal contrast between seeing an object as crimson in foveal vision versus merely as red in peripheral vision. The solution I favor is to model mental qualities using regions, rather than points. I explain how this seemingly simple formal innovation not only provides a natural way of modeling precision, but also yields a variety of further theoretical fruits: it enables us to formulate novel hypotheses about the space and structures of mental qualities, formally differentiate two dimensions of phenomenal similarity, generate a quantitative model of the phenomenal sorites, and define a measure of discriminatory grain. A noteworthy consequence is that the structure of the mental qualities of conscious experiences is fundamentally different from the structure of the perceptible qualities of external objects.

Epiphenomenalism is the view that phenomenal properties – which characterize what it is like, or how it feels, for a subject to be in conscious states – have no physical effects. One of the earliest arguments against epiphenomenalism is the evolutionary argument (James 1890/1981; Eccles and Popper 1977; Popper 1978), which starts from the following problem: why is pain correlated with stimuli detrimental to survival and reproduction – such as suffocation, hunger and burning? And why is pleasure correlated with (...) stimuli beneficial to survival and reproduction – such as eating and breathing? According to the argument, the fact that we have these particular correlations and not other ones must have an evolutionary explanation. But given epiphenomenalism, differences in phenomenal properties could not cause differences in fitness, so natural selection would not be expected to favor these correlations over any other ones. Epiphenomenalism thus renders these correlations an inexplicable coincidence, and should therefore be rejected. The evolutionary argument has been widely criticized and few have deemed it cogent (Broad 1925; Jackson 1982; Robinson 2007; Corabi 2014). In this paper, I will consider previous and potential criticisms and conclude some of them are indeed fatal to the argument if it is understood, as it traditionally has been, as an argument for any standard version of non-epiphenomenalism such as physicalism and interactionism. I will then offer a new and improved version of the argument, as an argument for a particular non-epiphenomenalist view, which I will call the phenomenal powers view. This is the view that phenomenal properties produce and thereby (metaphysically) necessitate their effects in virtue of how they feel, or in virtue of their intrinsic, phenomenal character alone – along the lines of C. B. Martin and John Heil’s powerful qualities view (Martin and Heil 1999; Heil 2003). I will argue that the phenomenal powers view explains the correlations given natural selection far better than any other view. It follows that if (and only if) understood as an argument for the phenomenal powers view, the evolutionary argument is far stronger than it is usually thought to be. (shrink)

Imagism about Phenomenal Thought is (roughly) the view that there is some concept *Q* (for some sensory quality Q) that we can employ only while we experience the quality Q. I believe this view is theoretically significant, is or can be made intuitively appealing, and is explicitly or implicitly accepted by many contemporary philosophers However, there is no good reason to accept it. Or so I argue.

It is often thought that consciousness has a qualitative dimension that cannot be tracked by science. Recently, however, some philosophers have argued that this worry stems not from an elusive feature of the mind, but from the special nature of the concepts used to describe conscious states. Marc Champagne draws on the neglected branch of philosophy of signs or semiotics to develop a new take on this strategy. The term “semiotics” was introduced by John Locke in the modern period – (...) its etymology is ancient Greek, and its theoretical underpinnings are medieval. Charles Sanders Peirce made major advances in semiotics, so he can act as a pipeline for these forgotten ideas. Most philosophers know Peirce as the founder of American pragmatism, but few know that he also coined the term “qualia,” which is meant to capture the intrinsic feel of an experience. Since pragmatic verification and qualia are now seen as conflicting commitments, Champagne endeavors to understand how Peirce could (or thought he could) have it both ways. The key, he suggests, is to understand how humans can insert distinctions between features that are always bound. Recent attempts to take qualities seriously have resulted in versions of panpsychism, but Champagne outlines a more plausible way to achieve this. So, while semiotics has until now been the least known branch of philosophy ending in –ics, his book shows how a better understanding of that branch can move one of the liveliest debates in philosophy forward.

Quantities like mass and temperature are properties that come in degrees. And those degrees (e.g. 5 kg) are properties that are called the magnitudes of the quantities. Some philosophers (e.g., Byrne 2003; Byrne & Hilbert 2003; Schroer 2010) talk about magnitudes of phenomenal qualities as if some of our phenomenal qualities are quantities. The goal of this essay is to explore the anti-physicalist implication of this apparently innocent way of conceptualizing phenomenal quantities. I will first argue for (...) a metaphysical thesis about the nature of magnitudes based on Yablo’s proportionality requirement of causation. Then, I will show that, if some phenomenal qualities are indeed quantities, there can be no demonstrative concepts about some of our phenomenal feelings. That presents a significant restriction on the way physicalists can account for the epistemic gap between the phenomenal and the physical. I’ll illustrate the restriction by showing how that rules out a popular physicalist response to the Knowledge Argument. (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)

This paper starts by providing a succinct overview of the sensorimotor approach to phenomenal consciousness, describing its two parts: the part that concerns the quality of sensations, and the part that concerns whether or not such qualities are (consciously) experienced. The paper goes on to discuss the explanatory status of the approach, claiming that the approach does not simply “explain away” qualia, but that on the contrary, it provides a way of thinking about qualia that explains why they (...) are the way they are, stimulates scientific paradigms and produces testable predictions. A final part of the paper examines the relation of the theory to radical enactivism, claiming that some kind of “higher order” cognitive mechanism similar to that used in Higher Order Thought theories of consciousness is needed to account for what is usually meant by being conscious of something.

Given the hard problem of consciousness, there are no brain electrophysiological correlates of the subjective experience (the felt quality of redness or the redness of red, the experience of dark and light, the quality of depth in a visual field, the sound of a clarinet, the smell of mothball, bodily sensations from pains to orgasms, mental images that are conjured up internally, the felt quality of emotion, the experience of a stream of conscious thought, or the phenomenology (...) of thought). However, there are occipital and left temporal brain electrophysiological correlates of the subjective experience. Notwithstanding, as an evoked signal, the change in event-related brain potential phase (frequency is the change in phase over time) is instantaneous, that is, the frequency will transiently be infinite: a transient peak in frequency (positive or negative), if any, is instantaneous in electroencephalogram averaging or filtering that the event-related brain potentials required and the underlying structure of the event-related brain potentials in the frequency domain cannot be accounted for, for example, by the Wavelet Transform or the Fast Fourier Transform analysis, because they require that frequency be derived by convolution rather than by differentiation. However, as I show, one suitable method for analysing the instantaneous change in event-related brain potential phase and accounting for a transient peak in frequency (positive or negative), if any, in the underlying structure of the event-related brain potentials is the Empirical Mode Decomposition with post-processing Ensemble Empirical Mode Decomposition.

The Vienna Circle was a group of scientifically-minded philosophers, many physicists by training, who in the 1920s and 30s developed the cluster of philosophical doctrines known as Logical Positivism. Among the Circle’s most distinguished members were Rudolf Carnap and Herbert Feigl, each of whom emigrated to America during the Nazi era. It is said that Feigl, the author of an important 1958 monograph defending a materialist approach to the mind-body problem, once gave a visiting lecture on the problem of consciousness (...) at UCLA, where Carnap was teaching. Feigl argued that although there were good reasons for believing that the mind is fundamentally physical, the physical explanation of the ‘qualia’ of sensory experience – the ineffable sensory qualities involved in, say, smelling coffee – was still a mystery to science. Now the story becomes apocryphal. Carnap is supposed to have interrupted, ‘But Feigl, there is something missing from your lecture. Science is beginning to explain qualia in terms of the alpha factor!’. We can imagine Feigl somewhat alarmed by this interjection from the great Carnap: ‘But Carnap, please tell me: what is the alpha factor?’. ‘Well, Feigl’ Carnap replied ‘if you tell me what qualia are, I’ll tell you what the alpha factor is’.

The sensorimotor theory of perception and consciousness is frequently presented as a variety of anti-representationalist cognitive science, and there is thus a temptation to suppose that those who take representation as bedrock should reject the approach. This paper argues that the sensorimotor approach is compatible with representationalism, and moreover that representationalism about phenomenal qualities, such as that advocated by Tye, would be more complete and less vulnerable to criticism if it incorporated the sensorimotor account of conscious feel. The paper (...) concludes by arguing that the project of naturalizing phenomenal qualities would nonetheless be better served by abandoning ‘representation’ talk altogether, a move that would require only a small modification of existing representationalist accounts.

In the marketplace of opinions concerning the metaphysics of mind and consciousness panqualityism (PQ) occupies an interesting position. It is a distinct variant of neutral monism, as well as of protophenomenalism, and as such it strives to carve out a conceptual niche midway between physicalism and mentalism. It is also a brand of Russellian monism, advocated by its supporters as a less costly and less extravagant alternative to panpsychism. Being clearly articulated and relatively well-developed it constitutes an intriguing view. Nonetheless, (...) the present paper takes a decisively critical stance towards PQ. In particular, it challenges it on two principal grounds. First, I argue that PQ's analysis of experience, and of the qualities tasked with constituting the phenomenal character of experience, is fundamentally flawed. Second, I argue that PQ's attempt to explain phenomenal consciousness as a function of reflective awareness is equally misguided. Along the way, the paper also points the shortcomings of previously established critiques of PQ. All in all, the discussion identifies some difficulties that are likely to generalize beyond PQ's specific circumstances, raising concerns regarding the viability of a "middle of the road" solution to the mind–body problem.

I elaborate and defend a set of metaphysical and epistemic claims that comprise what I call the acquaintance approach to introspective knowledge of the phenomenal qualities of experience. The hallmark of this approach is the thesis that, in some introspective judgments about experience, (phenomenal) reality intersects with the epistemic, that is, with the subject’s grasp of that reality. In Section 1 of the paper I outline the acquaintance approach by drawing on its Russellian lineage. A more detailed picture (...) of the approach emerges in succeeding sections, which respond to a range of objections. Some critics charge that approaches of this sort are overly idealized, in that they ignore the cognitive flaws and limitations of actual human beings. I begin to address these worries in Section 2, by arguing that the epistemic commitments of the acquaintance approach are in fact relatively modest. In Section 3, I sketch a picture of introspective reference that explains how phenomenal reality can intersect with the epistemic in a phenomenal judgment, as the acquaintance approach requires. Drawing on this picture of introspective reference, Section 4 sets out a practical strategy for achieving knowledge by acquaintance. Some contemporary acquaintance theorists (BonJour 2003, Fumerton 1996) employ demanding epistemic standards for knowledge by acquaintance, standards beyond those mandated by the acquaintance approach. In Section 5 I show that instances of introspective knowledge that meet less demanding standards can satisfy the acquaintance approach’s epistemic commitments. The final sections concern the most direct challenges to the acquaintance approach, which target the claim that phenomenal reality intersects with the epistemic. According to one such challenge, this claim is belied by the fact that possessing a phenomenal concept is a matter of having certain dispositions. Section 6 draws on a discussion by Sosa (2003) to articulate this challenge, and responds to it on behalf of the acquaintance approach. Section 7 addresses Stalnaker’s (2008) worry that, if phenomenal reality intersected with the epistemic, phenomenal information would be incommunicable. (shrink)

Phenomenal qualities are embodied spaciotemporal abstractions subjectively perceived by a conscious observer. Specific examples, i.e., qualia, include the color purple, the taste of chocolate, and the fragrance of a rose. The question of whether phenomenal awareness can be empirically understood forms one important facet of the “Hard Problem of Consciousness” (Chalmers, 1995, pp. 200–219). It is the position of this analysis that we will never understand why we experience sensory qualities in the manner we do until we first (...) comprehend how they may have evolved in the very distant past. This examination explores the evolutionary development of phenomenal experience. In so doing, it proposes that behind the mechanisms through which external stimuli interface with our sensory apparatus, there lies a long evolutionary process of standardization, approximation, and synchronization that has ultimately forged the close links between the two. The consistent and efficient correlations that the resultant evolutionary links give rise to cumulatively generate conscious experience. There is a tight correspondence between our sensations and incoming stimuli, and this synchronous covariance is meaningful and functional; however, it does not result from a strict cause-and-effect relationship between the physical properties of external objects and our internal neurophysiology. As such, this investigation endorses Hoffman’s (1998, 2003, 2008, 2009) view that the external world is largely hidden from direct sensory evaluation. The following inquiry utilizes Jung’s (1952) “Acausal Connecting Principle” to further explore the concept of complementary sensory phenomena as it may have originally been envisioned by Wolfgang Pauli. (Meier, 2001) This thesis, with respect to meaningful acausality and synchronicity, is first used to provide a plausible explanation for the initial genetic development of color perception, and then employed to examine the analogous evolutionary ties that ultimately engender all sensory modalities. Without invoking the Quantum-Mind hypothesis, this paper supports the idea that our five senses are not direct, or true, or even approximate abstract representations of any underlying material properties of incoming stimuli; instead, they efficiently provide useful higher-order assumptions pertaining to the macro properties of spacetime, matter, and motion, as well as the causal-objective of all life. The overall investigation concludes that it is the structural categorization, hierarchical organization, and qualitative characterization of this indirect presumptive meta-information that has engendered meaningful sensory experience, and all conscious thought over evolutionary time.

The objective of the current paper is to provide a critical analysis of Dretske's defense of the naturalistic version of the privileged accessibility thesis. Dretske construed that the justificatory condition of privileged accessibility neither relies on the appeal to perspectival ontology of phenomenal subjectivity nor on the functionalistic notion of accessibility. He has reformulated introspection (which justifies the non-inferentiality of the knowledge of one's own mental facts in an internalist view) as a displaced perception for the defense of naturalistic (...) privileged accessibility. Both internalist and externalist have been approved the plausibility of first-person authority argument through privileged accessibility; however, their disagreement lies on the justificatory condition of privileged accessibility. Internalist hold the view that the justificatory warrant for privileged accessibility is grounded on phenomenal subjectivity. In contrast to the internalist view, externalists uphold the view that the justificatory condition for privileged accessibility lies outside the domain of phenomenal subjectivity. As a proponent of naturalistic content externalism, Dretske defends the view that subject's privileged accessibility is not due to having access to the particular representational state (hence, they have the privilege of getting sensory representational information) and the awareness of mental fact rather the awareness of the whole representational mechanism. Having the knowledge of a particular representational state through privileged access is not the sufficient condition for the accuracy of knowledge about one’s own mental facts. The justificatory warrant lies external to the subject. Even though Dretske’s naturalistic representation is not plausible enough while dealing with the reduction of phenomenal qualities of experience, however, provides a new roadmap to compatibilists for the defense of privileged accessibility and has a major impact on transparency theorists.

The materialist version of the mind/brain identity theory has met with considerable challenges from philosophers of mind. The author first dispenses with a popular objection to the theory based on the law of indiscernibility of identicals. By means of discussing the vexatious problem of phenomenal qualities, he explores how the debate may be advanced by seeing each dualist and monist ontology through the lens of an evolutionary epistemology. The author suggests that by regarding each ontology as the core of (...) a scientific research programme, each of these logically irrefutable hypotheses can be tested rationally. (shrink)

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes (...) in degrees. Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

The sense of touch provides us knowledge of two kinds of events. Tactile sensation (T) makes us aware of events on or just below the skin; haptic perception (H) gives us knowledge of things outside the body with which we are in contact. This paper argues that T and H are distinct experiences, and not (as some have argued) different aspects of the same touch-experience. In other words, T ≠ H. Moreover, H does not supervene on T. Secondly: In T, (...) we are aware of immanent, phenomenal qualities; in H, we come to know of transcendent qualities in things that exist independently of ourselves. Finally: T is non-spatial; it is indexed by parts of the body, but not by position in space. H, by contrast, is spatial. This brings to mind Kant’s contention that things are presented as existing objectively when they are represented spatially. (shrink)

In consciousness science, several promising approaches have been developed for how to represent conscious experience in terms of mathematical spaces and structures. What is missing, however, is an explicit definition of what a 'mathematical structure of conscious experience' is. Here, we propose such a definition. This definition provides a link between the abstract formal entities of mathematics and the concreta of conscious experience; it complements recent approaches that study quality spaces, qualia spaces or phenomenal spaces; it provides a (...) general method to identify and investigate structures of conscious experience; and it may serve as a framework to unify the various approaches from different fields. We hope that ultimately this work provides a basis for developing a common formal language to study consciousness. (shrink)

Representationalism is the view that the phenomenal character of experiences is identical to their representational content of a certain sort. This view requires a strong transparency condition on phenomenally conscious experiences. We argue that affective qualities such as experienced pleasantness or unpleasantness are counter-examples to the transparency thesis and thus to the sort of representationalism that implies it.

I examine Michel Bitbol’s proposal of a metaphysical counterpart of neurophenomenology, arguing that such a metaphysics should address the issue of the origin of consciousness. This can be accomplished through panqualityism, which conceives of the subject and object of experience as grounded in a flow of pre-phenomenal qualities. I conclude by framing this view in terms of a critical metaphysics that is consistent with the pragmatic and existential dimension of neurophenomenology.

Does inner sense, like outer sense, provide inner sensations or, in other words, a sensory manifold of its own? Advocates of the disparity thesis on inner and outer sense claim that it does not. This interpretation, which is dominant in the preexisting literature, leads to several inconsistencies when applied to Kant’s doctrine of inner experience. Yet, while so, the parity thesis, which is the contrasting view, is also unable to provide a convincing interpretation of inner sensations. In this paper, I (...) argue that this deadlock can be traced back to an inadequate understanding of inner sense shared by both sides. Drawing upon an analysis of the notion of obscure representations, I offer an alternative interpretation of inner sense with a special regard to self-affection, apprehension, and attention. From this basis, I will infer that outer sense delivers sensory content that is initially and intrinsically unaccompanied by phenomenal consciousness; inner sense contributes by endowing such content with phenomenal consciousness. Therefore, phenomenal qualities can be regarded as the sensory manifold of inner sense. This alternative interpretation solves the long-standing dispute concerning inner sensations and would further illuminate Kant’s notion of inner experience. (shrink)

It is widely held that it is only contingent that the sensation of pain is disliked, and that when pain is not disliked, it is not intrinsically bad. This conjunction of claims has often been taken to support a subjectivist view of pain’s badness on which pain is bad simply because it is the object of a negative attitude and not because of what it feels like. In this paper, I argue that accepting this conjunction of claims does not commit (...) us to this subjectivist view. They are compatible with an objectivist view of pain’s badness, and with thinking that this badness is due to its phenomenal quality. Indeed, I argue that once the full range of options is in view, the most plausible account of pain is incompatible with subjectivism about value. (shrink)

This article argues that religious emotions are variations of general emotions that we already know from our everyday life, which nevertheless exhibit specific features that enable us to think of them as forming a coherent subclass. The article claims that there is an experience of joy, sorrow, regret, fear, and so on that is specifically religious. The aim is to develop an account that specifies what makes them “religious.” The argument is developed in three stages. The first section develops a (...) phenomenologically inspired account of the emotions by focusing on three of their moments: phenomenal quality, cognitive dependency, and intentionality. Drawing on this theory, section 2 distinguishes the class of religious emotions from similar phenomena. The third and final section examines the main features of religious emotions. (shrink)

Some have argued that a subject has an inner awareness of its conscious mental states by virtue of the non-introspective, reflexive awareness that any conscious state has of itself. But, what exactly is it like to have a ubiquitous and reflexive inner awareness of one’s conscious states, as distinct from one’s outer awareness of the apparent world? This essay derives a model of ubiquitous inner awareness (UIA) from Sebastian Watzl’s recent theory of attention as the activity of structuring consciousness into (...) an experiential center and periphery. I develop Watzl’s theory into an account of UIA by suggesting that a subject is acquainted with its own conscious mental states through being reflexively aware of how these states are structured by attention into a unified subjective perspective. I favorably compare this Watzl-inspired account of UIA against other contemporary analytic and classical Buddhist accounts of reflexive awareness and subjective character, which variously ground the inner awareness of conscious states on their intrinsic phenomenal quality of “for-me-ness,” their affective/hedonic valence, or a subject’s disposition to introspect them. The Watzl-inspired account also accommodates possible counter-examples to Watzl’s theory posed by states of minimal phenomenal experience such as lucid dreamless sleep and non-dual meditative awareness.

This paper suggests that reference to phenomenal qualities is best understood as involving iconicity, that is, a passage from sign-vehicle to object that exploits a similarity between the two. This contrasts with a version of the ‘phenomenal concept strategy’ that takes indexicality to be central. However, since it is doubtful that phenomenal qualities are capable of causally interacting with anything, indexical reference seems inappropriate. While a theorist like David Papineau is independently coming to something akin to iconicity, (...) I think some of the awkwardness that plagues his account would be remedied by transitioning to a more inclusive philosophy of signs. (shrink)

Contemporary accounts on fictional emotions, i.e., emotions experienced towards objects we know to be fictional, are mainly concerned with explaining their rationality or lack thereof. In this context dominated by an interest in the role of belief, questions regarding their phenomenal quality have received far less attention: it is often assumed that they feel “similar” to emotions that target real objects. Against this background, this paper focuses on the possible specificities of fictional emotions’ qualitative feel. It starts by (...) presenting what I call the “phenomenological question” about the qualitative feel of fictional emotions (section 1) and by showing that this is irreducible to questions about their cognitive, intentional, evaluative, and embodied nature (section 2). Drawing on some insights from early phenomenologists, the next two sections elaborate criteria to distinguish between real and sham emotions on the one side (section 3) and between genuine and non-genuine emotions on the other (section 4). Finally, I apply this orthogonal distinction to the particular case of fictional emotions (section 5). The paper argues that fictional emotions are neither sham emotions nor quasi-emotions, but full-fledged emotional experiences, despite them displaying the distinctive phenomenology of emotions experienced as non-genuine. In the particular case of fictional emotions, they are non-genuine because our psychology is in fact in a state dominated by aesthetic enjoyment. (shrink)

The science of the mind, and of consciousness in particular, needs carefully to consider people's common-sense views of the mind, not just what the mind really is. Such views are themselves an aspect of the nature of (conscious) mind, and therefore part of the object of study for a science of mind. Also, since the common-sense views allow broadly successful social interaction, it is reasonable to look to the common-sense views for some rough guidance as to the real nature of (...) the mind. On the other hand, to the extent that common-sense views are inaccurate, and perhaps even in gross conflict with the true nature of the mind, one interesting scientific question is: why do we hold such views, given our access to our own minds? Why should introspection be limited in a way that allows inaccurate views to hold sway? Now, common-sense views of the mind are revealed in natural language discourse that describes mental states, and such descriptions are largely metaphorical. The metaphors are used within thinking about the mind as well as in language. Therefore the study of metaphor is central to the study of mind. The present article is a preliminary study of the importance of metaphor in the scientific study of consciousness. It concentrates on analysing the nature of a range of important metaphors of mind, briefly discussing the extent to which they can be used to describe or qualify states of consciousness, and pointing to important questions about the nature of consciousness that the study of the metaphors raises. The article further conjectures that the reason people use metaphors in describing themselves is often not (just) that they have intellectually worked out some structural analogy --- e.g., between interactions of physical objects in physical space and interactions of ideas in the mind --- but rather that they {\it feel} their own minds to be as described by the metaphor --- e.g., they feel that the ideas in their minds are interacting physical entities. This matter of how a mind feels to itself is an aspect of the central issue of consciousness, namely its phenomenal quality. -/- (NB: The archived file is a preprint. However, it is substantially the same as the published version.). (shrink)

In this article, I argue that consciousness is a unique way of processing information, in that: it produces information, rather than purely transmitting it; the information it produces is meaningful for us; the meaning it has is always individuated. This uniqueness allows us to process information on the basis of our personal needs and ever-changing interactions with the environment, and consequently to act autonomously. Three main basic cognitive processes contribute to realize this unique way of information processing: the self, attention (...) and working memory. The self, which is primarily expressed via the central and peripheral nervous systems, maps our body, the environment, and our relations with the environment. It is the primary means by which the complexity inherent to our composite structure is reduced into the “single voice” of a unique individual. It provides a reference system that (albeit evolving) is sufficiently stable to define the variations that will be used as the raw material for the construction of conscious information. Attention allows for the selection of those variations in the state of the self that are most relevant in the given situation. Attention originates and is deployed from a single locus inside our body, which represents the center of the self, around which all our conscious experiences are organized. Whatever is focused by attention appears in our consciousness as possessing a spatial quality defined by this center and the direction toward which attention is focused. In addition, attention determines two other features of conscious experience: periodicity and phenomenal quality. Self and attention are necessary but not sufficient for conscious information to be produced. Complex forms of conscious experiences, such as the various modes of givenness of conscious experience and the stream of consciousness, need a working memory mechanism to assemble the basic pieces of information selected by attention.

Vehicle externalists hold that the physical substrate of mental states can sometimes extend beyond the brain into the body and environment. In a particular variation on vehicle externalism, Susan Hurley (1998) and Alva Noë (2004) have argued that perceptual states, states with phenomenal qualities, are among the mental states that can sometimes spread beyond the brain. Their vehicle externalism about perceptual states will be the main topic of this article. In particular, I will address three strong objections to their (...) vehicle externalism, objections by Ned Block (2005), Jesse Prinz (2006), and Fred Adams & Ken Aizawa (2008). Though in some ways these objections appear disparate, I will argue that all of them depend on a crucial presupposition, one which Hurley, Noë, and their sympathizers should reject. This presupposition is that perceptual character is fixed by an instantaneous snapshot of neural states, a view that Hurley dubbed ‘temporal atomism.’ To put the presupposition in more familiar terms, all three objections are implicitly committed to something like Dennett’s Cartesian Theater (1991). -/- In the first part of the article, I will discuss Hurley and Noë’s views, and include reasons why their views entail the rejection of the Cartesian Theater. In the next part of the article I will introduce the three objections and show how they presuppose something like a Cartesian Theater. I will also show that, if the Cartesian Theater is rejected, the objections all vanish. In the final part of the article I address the charge that Noë and Hurley confuse causation with constitution. This charge reveals a lack of appreciation for the way in which dynamical explanation motivates Hurley’s externalism. (shrink)

What does it take for a subject to experience a personal memory as being her own? According to Fernández’ (2019) model of endorsement, this particular phenomenal quality of our memories, their “sense of mineness”, can be explained in terms of the experience of the mnemonic content as veridical. In this article, I criticize this model for two reasons: (a) the evidence that is used by Fernández to ground his theoretical proposal is dubious; and more importantly, (b) the endorsement (...) model does not accommodate many non-pathological everyday memories that preserve their sense of mineness, but whose veridicality is explicitly denied, suspected, not automatically endorsed, or neither denied nor endorsed. Finally, I sketch two alternative explanations: one also problematic, the other one more promising, and present some normative advantages of the latter. This also displays the undesirability of the endorsement model from a normative perspective. (shrink)

The sensorimotor theory is an influential account of perception and phenomenal qualities that builds, in an empirically supported way, on the basic claim that conscious experience is best construed as an attribute of the whole embodied agent's skill-driven interactions with the environment. This paper, in addition to situating the theory as a response to certain well-known problems of consciousness, develops a sensorimotor account of why we are perceptually conscious rather than not.

Panpsychism, the view that consciousness is present everywhere at the fundamental level of reality, has established itself as an increasingly popular option in the philosophy of mind. Situated between substance dualism and reductive physicalism, panpsychism aims to capture the intuitions behind both, integrating consciousness into the physical world without explaining it in terms of purely physical facts. In this thesis, I offer a defence of panpsychism. -/- First, I examine influential arguments against physicalism, such as Thomas Nagel’s (1974, 1979) perspective-based (...) proposal, Frank Jackson’s (1982) knowledge argument, David Chalmers’ (1996, 2010) conceivability argument, as well as vagueness arguments (Antony 2006a; Tye 1996). I argue that none of them offers a knockdown case against physicalism, particularly because of the threat presented by the phenomenal concept strategy (Chalmers 2007; Papineau 2007a), though they suggest panpsychism as a promising alternative that avoids many common objections. -/- Second, I discuss independent arguments for panpsychism, including the Russellian monist view (Goff 2017; Russell 1927/1992), the intrinsic nature argument (Seager 2006; Strawson 2006), recent developments in the literature as presented by Hedda Hassel Mørch (2018, 2020) and Luca Dondoni (2022), Tye’s (2021b) representational panpsychism based on the vagueness argument, as well as cosmopsychism (Nagasawa & Wager 2016; Shani 2015) – an alternative to panpsychism that shares its aims whilst claiming to avoid its shortcomings. -/- Third, I address the most pressing objection to panpsychism: the combination problem or the question of how fundamental consciousness can combine to lead to complex consciousness (James 1890). Focusing especially on the subject-summing version of the combination problem or the issue of how small subjects can combine to form complex subjects, I go over various proposals for either solving or avoiding it, such as Philip Goff’s (2016) phenomenal bonding relation and William Seager’s (2010) combinatorial infusion proposal, arguing against both and agreeing at the end with Sam Coleman (2014), who advocates that subject-summing is demonstrably incoherent. -/- However, as I argue in the fourth and final chapter, the panpsychist still has an option that avoids the subject-summing problem, while also circumventing the objections faced by the alternative view of cosmopsychism. Inspired though not reliant on the philosophy of Gottfried Wilhelm Leibniz (1902/2005), I introduce what I call monadic panpsychism, the view that the phenomenal character of any given consciousness-bearing physical ultimate is determined by its relations to other such ultimates featuring in the relevant causal structure. -/- The theory consists of two key claims. The first is that phenomenal qualities are relational rather than intrinsic. This view has precedent in literature on the philosophy of mind, such as in Rudolf Carnap (1928), Gottlob Frege (1956), Moritz Schlick (1959), as well as more recently in David Hilbert and Mark Kalderon (2000) and Austen Clark (2000), though not in the context of panpsychism. -/- The second claim is that physical ultimates only possess a very basic form of consciousness necessary for experiencing as such. There are many ways to conceptualise this basic consciousness: non-relational or intrinsic, rudimentary and non-specific, a point of view without experiences, the minimal subject, a mere conduit for experience, phenomenal space, etc. Russellian panpsychists offer a more detailed proposal in which every physical ultimate has an appropriate associated type of experience. For example, all quarks have the same quark-type of experience, assuming for the sake of discussion that quarks are ultimates. Still, arguing for a more minimal notion, as I do, requires making less claims and should not be controversial to any panpsychist. -/- So, what follows from these two claims? I propose that the relational constitution of phenomenal qualities has its endpoint at the fundamental level rather than at the level of a combined complex or emergent subject. Put simply, physical ultimates guarantee the basic consciousness or the point of view that I occupy, while the relational structure constitutes my rich and full human experience. So to speak, relationally constituted phenomenal qualities ‘anchor’ themselves in physical ultimates. As long as these relations result in a phenomenally unified experience, which is an uncontroversial thesis, then no matter where that process reaches the end of its causal chain, it will necessarily be experienced from a subjective point of view. -/- Since only qualities but not subjects need to combine, my proposal avoids the subject-summing version of the combination problem, which is arguably an insurmountable challenge to other forms of panpsychism. Because of this, I conclude that my theory contributes to the field, serving as a good starting point for further developments of neither combinatory nor emergent panpsychism with regard to subjects.

In Sense and Content , Christopher Peacocke points out that two equally-sized trees at different distances from the perceiver are normally represented to be the same size, despite the fact that in a certain sense the nearer tree looks bigger ; he concludes on the basis of this observation that visual experiences possess irreducibly phenomenal properties. This argument has received the most attention of all of Peacocke’s arguments for separatism—the view that the intentional and phenomenal properties of experiences (...) are independent of one another. However, despite its notoriety, the argument is widely misunderstood and underappreciated. I argue that once the structure of the argument is clarified and the replies that have been offered are considered closely, one must conclude that the trees argument is successful. (shrink)

Research on the specific features of daydreaming compared with mind-wandering and night dreaming is a neglected topic in the philosophy of mind and the cognitive neuroscience of spontaneous thought. The extant research either conflates daydreaming with mind-wandering (whether understood as task-unrelated thought, unguided attention, or disunified thought), characterizes daydreaming as opposed to mind-wandering (Dorsch, 2015), or takes daydreaming to encompass any and all “imagined events” (Newby-Clark & Thavendran, 2018). These dueling definitions obstruct future research on spontaneous thought, and are insufficiently (...) precise to guide empirical studies. They also fail to illuminate the phenomenal core of daydreaming, namely, its dreamlike qualities. Although daydreaming is related to both mind-wandering and narrative imagination, it is not reducible to either. We argue that daydreams are experiences of spontaneous, immersive imagination in the waking state. The main task of our investigation is to distinguish daydreaming, conceptually and phenomenologically, from mind-wandering, on the one hand, and night dreaming, on the other. Although daydream experiences can vary widely, we distinguish prototypical experiences of daydreaming from adjacent imaginative activity, including fleeting imagery and “focused daydreaming,” or crafted visualization. We consider our phenomenological analysis as preparatory work for conceptually distinguishing different spontaneous and imaginative states so that they can be investigated accordingly with questionnaires and qualitative methods. We argue that precision about the phenomenal character of daydreaming can guide neurophenomenological investigations, help delimit studies on individual variance in daydreaming features, and identify differences among daydreaming, mind-wandering, and night dreaming conceptually and phenomenologically, and possibly eventually in terms of neural correlates.

Barbara Montero considers whether or not we are able to remember what pain feels like. In order to properly answer this question, she introduces a new type of memory called 'qualitative memory', which seems common to exteroceptive sensations. Having concluded that there is arguably no qualitative memory for pain and other bodily sensations, Montero considers possible philosophical implications for areas including rational choice-making and empathy. In addressing the relationship between pain and memory, the paper raises an issue that has not (...) received much attention and indicates various interesting fields of research for which the apparent inability to remember pain might prove relevant. My comment primarily focuses on the core concepts of pain and qualitative memory which are foundational for the paper. I argue that a deeper engagement with some key aspects of these concepts is necessary. A more fine-grained discussion could have made Montero's argument more convincing. (shrink)

In questo lavoro distinguo tra due versioni della tesi del carattere incarnato della mente: “debole” e “forte”. Secondo la versione debole, il possesso di stati mentali presuppone l’esistenza di un corpo che si muove ed agisce nell’ambiente, ossia un corpo funzionale. Secondo la versione forte, invece, il possesso di stati mentali presuppone l’esistenza di un corpo non solo funzionale ma anche senziente, ossia: il corpo come sede della sensibilità o coscienza fenomenica. Sostengo che alcuni approcci all’interno della “scienza cognitiva incarnata” (...) implicano la forma debole di embodiment : la robotica di Brooks, l’enattivismo sensomotorio di Noë e O’Regan e l’enattivismo radicale di Hutto e Myin. In contrapposizione a queste prospettive, e basandomi sull’analisi fenomenologica della corporeità vivente e vissuta, difendo la forma forte di embodiment, secondo cui la mente si fonda essenzialmente sul corpo funzionale e senziente. Parole chiave: Fenomenologia; Embodiment; Coscienza fenomenica; Enattivismo; Qualità sensibili -/- Abstract (english) -/- Functional body and sentient body. The strong view on the embodied mind in phenomenology: In this paper, I draw a distinction between weak and strong versions of the “embodiment thesis”. The weak version claims that mental states are grounded in a body that moves and acts in the environment, i.e., a functional body. The strong version claims that mental states are grounded in a body that is not only functional but also sentient, i.e., a body that is the locus of sensibility or phenomenal consciousness. I argue that some approaches within the “new embodied cognitive science” – Brooks’ robotics, Noë’s and O’Regan’s sensorimotor enactivism, Hutto’s and Myin’s radical enactivism – imply a weak version of the embodiment thesis. In contrast, by drawing on a phenomenological analysis of living and lived corporeality, I argue for the strong version, which claims that the mind is essentially grounded in the functional and sentient body. Keywords: Phenomenology; Embodiment; Phenomenal Consciousness; Enactivism; Sensible Qualities. (shrink)

The aesthetic tradition has identified as paradigmatically sublime such objects as imposing mountains and intense storms, as well as monumental art. But the tradition also acknowledges less paradigmatic cases, including sometimes mathematical structures or abstract concepts. In this paper, we argue that there is also a case for considering phenomenal consciousness – the experiential quality of subjective awareness – as a sublime phenomenon. One appreciates this, we argue, when one is struck by (fitting) awe upon contemplating (a) the (...) perplexing existence of something like phenomenal consciousness in an otherwise completely material universe and (b) the role of consciousness in injecting meaning and value in an otherwise brutally factual reality.

The idea that appearances provide justifications for beliefs—the principle of phenomenal conservatism—is self-evidently true. In the case of cognitive penetration, however, it seems that certain irrational etiologies of a belief may influence the epistemic quality of that belief. Susanna Siegel argues that these etiologies lead to ‘epistemic downgrade.’ Instead of providing us with a decisive objection, cognitive penetration calls for us to clarify our epistemic framework by understanding the formative parts of appearances. In doing so, the two different (...) but inseparable ideas of sensation and intellection provide us with a basis of our appearances. These appearances, in turn, provide us with the objective evidence needed to test our judgements. Thus, the extra-sensory concepts of intellectual identification and the appearances they help form become an epistemic groundwork. (shrink)

The assumption that known physical laws are sufficient for explaining mental phenomena is flawed from the outset. Qualities such as phenomenal redness do not exist within the known physical laws so by definition they are incomplete. Now assuming a new law was added that could explain how some physical property or vibration causes or is associated with phenomenal redness it would not be enough because it still wouldn’t explain how different qualities are bound together into a subjective unity. (...) Assuming more additional laws could now explain the popping into existence of subjective selves this also would still not be enough because a subjective self that cannot be directly observed nor indirectly observed via its effects vanishes into non-existence. This implies that subjective selves must have causal efficacy. But this would require still additional physical laws or perhaps an accommodated interpretation of quantum physics because there is no current understanding of how a mind can change the probability distribution of matter. But even if an expanded quantum physics was understood this would still not be enough because no general law can determine the indexical fact that I am me and you are you. -/- Then the hard problem of consciousness is real, non-trivial and when taken seriously appears to be actually separate problems. 1. How are qualia generated from purely physical activity? This appears to be a strictly deterministic process. 2. The so called binding problem. That is how is that I hear a sound and see a visual scene and feel a bodily sensation, all separate modalities that are unrelated, and yet I experience them all at the same time? 3. Can it be that I am causally efficacious? It certainly seems that the actual feelings of pain and pleasure serve some real purpose. Since conscious entities can never be directly observed and are only known through their effects, if they have no effects they disappear altogether. 4. The so called problem of indexicality. That is why I am me and not you. This seems to be a real fact above and beyond any objective fact. Eliminative materialism ignores the empirical evidence that phenomenal qualities exist and in doing so attains logical consistency. Other forms of emergence that try to explain qualia and give it a meaning while being restricted to physical closure are illogical. I explore these hard problems and arrive at a justification for a panpsychic interactive dualism. (shrink)

The following paper is a panpsychist metaphysics and seeks to avoid any radical emergence of mentality. Science has progressed by stripping the world of all mental qualities but a complete understanding of the world must ultimately put these back. The two types of mental qualities that must be reinstated as fundamentals are the private worlds of individual subjects and phenomenal qualities like colors. I view these as separate aspects of mind although they have a history of being conflated. In (...) this proposal qualities or proto-qualities exist in the public domain and are not restricted to or fenced into the private minds of subjects. Thus there is a fundamental dualism as both private efficacious conscious observers and publically observable phenomenal qualities exist as natural entities at the most basic level. -/- The following is a simple model example: Suppose electrons of certain vibrational energy levels always radiate the color blue while others of different vibrational energy levels radiate different colors thereby expressing universal psychophysical bridging laws. Electrons are mental subjects and within an atom can all perceive each other and orchestrate their actions to create the probabilistic atomic structure. The psychophysical laws that cause generation of phenomenal qualities as public objects are universal and the qualities are the identical ones that are observed by the higher level subjects. -/- In this model all minds at lower and higher levels are fundamental particles that have causal efficacy. The difference is the lowest level particles move themselves by influencing the direction and timing of their own quantum jumps while the higher level minds influence the probability distribution of the quantum jumps of lower level ones. Unlike Leibnizian monads these monads have windows and can really view each other and interact. Then the world can be seen as a communication network of interacting individuals each broadcasting and receiving information in a universal language of phenomenal qualities. (shrink)

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