When you have a conscious experience—such as feeling pain, watching the sunset, or thinking about your loved ones—are you aware of the experience as your own, even when you do not reflect on, think about, or attend to it? Let us say that an experience has “mineness” just in case its subject is aware of it as her own while she undergoes it. And let us call the view that all ordinary experiences have mineness “typicalism.” Recently, Guillot has offered a (...) novel argument for typicalism by leveraging the relation between self-knowledge and self-awareness. She starts by arguing that all ordinary experiences give their subjects immediate justification to believe that their experiences are their own. She then argues that this can be explained by typicalism. In this paper, I argue that her argument fails. I start by clarifying the notion of mineness and giving more details about her argument. I then explain why her argument fails by raising doubts about whether typicalism explains the target explanandum. I close by considering some implications of our discussion for self-knowledge.

I aim to show that, contrary to standard deflationary or eliminativist theories of the self, we can argue from the phenomenology of pre-reflective self-awareness for the thesis that subjects of experience are substances. The phenomenological datum of subjectivity points to a specific metaphysical structure of our experience, that is, towards the substance view rather than the bundle or the minimal self view. Drawing on modern philosophical accounts of pre-reflective self-awareness, mineness and (self-) acquaintance, I will argue that a subject is (...) aware of being the one individual who has many experiences and that it is revealed to the subject that it is the bearer of experiences and their unifier. The subject is present in pre-reflective awareness and known as the subject of experiences, and even this minimal self-awareness gives us reason to favour the substance view. Thus, one can demonstrate how the debates on the phenomenology of pre-reflective self-awareness and the metaphysics of selfhood intersect. (shrink)

Most recent philosophical theories of consciousness account for it in terms of representation, the bulk of the debate revolving around whether (suitably) representing something is sufficient for consciousness (as per first-order representationalism) or some further (meta-)representation is needed (as per higher-order representationalism and self-representationalism). In this paper, I explore an alternative theory of consciousness, one that aims to explain consciousness not in terms of representation but in terms of the epistemically and metaphysically direct relation of acquaintance. I call this the (...) Inner Acquaintance Theory of consciousness (IAT). Roughly, on IAT, what makes a mental state conscious is its subject being acquainted with it. Though not wholly unprecedented, IAT is still at the fringe of consciousness debates and remains largely underexplored. The main goal of this paper is to take some steps toward developing the details of IAT, illustrate its potential explanatory power, and put it forward as a plausible alternative to representational theories, with the hope that this will contribute to shifting IAT closer to the center of the debate. Here is how I proceed. In §2 I introduce a notion—inner awareness—that is crucial both to contextualize and to understand IAT. In §3 I provide some preliminary motivation for exploring IAT. In §4 I explain the notion of acquaintance and illustrate some of the features that are typically attributed to it in the literature. The details of IAT are then shaped through four main decision points. I address them in §§5-8, where I suggest a particular choice at each decision point, thereby progressively building up a view that I consider particularly promising. (shrink)

How the mind works is the ultimate mystery for human beings. To answer this question, one of the most significant insights is Kant’s argument that we can only perceive phenomena but not the essence of the external world. Following this idea, we formulated a novel computational framework to model the mind based on two assumptions: 1) There is no presupposition of the existence of the external objective world and the main task of the mind is to explore, establish and utilize (...) persistent relationships between senses and actions. 2) Symbolic intermediate-level representation is necessary. We call this framework the self-programming system. Based on the self-programming system, we interpreted the nature of concepts, time, space, causality, and consciousness. Besides that, we also draw a conclusion to the mind-body problem. Specifically, the perspective that considers subjective experience as fundamental is compatible with the existence of the external world and that the physical body serves as the substrate of the mind. However, since the relationship is “compatible” rather than “cause”, skepticism can never be ruled out in principle. Furthermore, we have elucidated the nature of interpretation within the context of reductive physicalism. This serves to provide a clear understanding as to why the hard problem of consciousness is inherently unsolvable. (shrink)

The starting point of this paper is the thought that the phenomenal appearances that accompany mental states are somehow only there, or only real, from the standpoint of the subject of those mental states. The world differs across subjects in terms of which appearances obtain. Not only are subjects standpoints across which the world varies, subjects are standpoints that we can ‘adopt’ in our own theorizing about the world (or stand back from). The picture that is suggested by these claims (...) has an appeal but is at the same time obscure and stands in need of regimentation. This paper explores and motivates a metaphysical account of what it is for subjects to be standpoints, what it is to adopt standpoints in our representations and, most importantly, how these notions might help us better understand the subjective character of conscious mental states. Some well-known observations by Thomas Nagel serve as starting points and the paper concludes by revisiting Nagel’s argument for the inevitable incompleteness of objective accounts of mental states, which will be reframed in terms of the central commitments of the proposed framework.

The primary goal of this paper is to provide substantial motivation for exploring an Acquaintance account of phenomenal consciousness, on which what fundamentally explains phenomenal consciousness is the relation of acquaintance. Its secondary goal is to take a few steps towards such an account. Roughly, my argument proceeds as follows. Motivated by prioritizing naturalization, the debate about the nature of phenomenal consciousness has been almost monopolized by representational theories. Among them, Self-Representationalism is by far the most antecedently promising. However, on (...) thorough inspection, Self-Representationalism turns out not explanatorily or theoretically better than the Acquaintance account. Indeed, the latter seems to be superior in at least some important respects. Therefore, at the very least, there are good reasons to take the Acquaintance account into serious consideration as an alternative to representational theories. The positive contribution of this paper is a sketch of an account of consciousness on which phenomenal consciousness is explained partly in representationalist terms, but where a crucial role is played by the relation of acquaintance.

Paul (2014, 2015a) argues that one cannot rationally decide whether to have a transformative experience by trying to form judgments, in advance, about (i) what it would feel like to have that experience, and (ii) the subjective value of having such an experience. The problem is if you haven’t had the experience then you cannot know what it is like, and you need to know what it is like to assess its value. However, in earlier work I argued that ‘what (...) it is like’-knowledge comes in degrees, and I briefly suggested that, consequently, some instances of Paul’s argument schema might commit a fallacy of equivocation. The aim of this paper is to further explore and strengthen this objection by, first, offering a new argument—the modelling argument—in support of it, and then by evaluating a range of replies that might be given to this objection on Paul’s behalf. I conclude that each reply either fails or, at best, only partially succeeds in defending some but not all instances of Paul’s argument schema. In closing, I consider how we might revise Paul’s concepts of transformative experiences and choices in response to this conclusion. (shrink)

How could physicalism be true of a world in which there are no fundamental physical phenomena? A familiar answer, due to Barbara Gail Montero and others, is that physicalism could be true of such a world if that world does not contain an infinite descent of mentality. Christopher Devlin Brown has produced a counterexample to that solution. We show how to modify the solution to accommodate Brown’s example: physicalism could be true of a world without fundamental physical phenomena if that (...) world does not contain an infinite descent of mentally constituted mentality. This solution is independently plausible and is available to physicalists of virtually all significant varieties. (shrink)

We argue that the projective geometrical component of the Projective Consciousness Model can account for key aspects of pre-reflective self-consciousness and can relate PRSC intelligibly to another signal feature of subjectivity: perspectival character or point of view. We illustrate how the projective geometrical versions of the concepts of duality, reciprocity, polarity, closedness, closure, and unboundedness answer to salient aspects of the phenomenology of PRSC. We thus show that the same mathematics that accounts for the statics and dynamics of perspectival character (...) also accounts for PRSC. More generally, we argue that introducing higher-level geometrical concepts into the theory of PRSC, and into the theory of consciousness broadly, as the PCM does, promises to break longstanding theoretical impasses and dialectical stalemates.

Illusionism is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Many opponents to the thesis take it to be obviously false. They think that they can reject illusionism, even if they conceded that it is coherent and supported by strong arguments. David Chalmers has articulated this reaction to illusionism in terms of a “Moorean” argument against illusionism. This argument contends that illusionism is false, because it is obviously true that we have phenomenal experiences. I argue (...) that this argument fails by showing that its defenders cannot maintain that its crucial premise has the kind of support needed for the argument to work, without begging the question against illusionism.

A growing movement in contemporary philosophy of mind is looking back on Indian thought to gain new insights into the problem of consciousness. This paper weighs the prospects of thinking about mentality through the lenses of Śaṅkaran Advaita Vedānta. To start, I outline micropsychist and cosmopsychist accounts of consciousness, introduce Śaṅkaran monism, and describe a potential reason of attraction of the framework over micropsychist and cosmopsychist alternatives. I then show that the eliminativist commitments of the view threaten to yield a (...) self-defeating account of ordinary experience, and that Advaitins took the accommodation of the issue to be beyond the reach of rational inquiry. Finally, I discuss how the analytical debate over Śaṅkaran monism might proceed based on these premises. (shrink)

I define two metaphysical positions that anti-physicalists can take in response to Jonathan Schaffer’s ground functionalism. Ground functionalism is a version of physicalism where explanatory gaps are everywhere. If ground functionalism is true, arguments against physicalism based on the explanatory gap between the physical and experiential facts fail. In response, first, I argue that some anti-physicalists are already safe from Schaffer’s challenge. These anti-physicalists reject an underlying assumption of ground functionalism: the assumption that macrophysical entities are something over and above (...) the fundamental entities. I call their position “lightweight anti-physicalism.” Second, I go on to argue that even if anti-physicalists accept Schaffer’s underlying assumption, they can still argue that the consciousness explanatory gap is especially mysterious and thus requires a special explanation. I call the resulting position “heavyweight anti-physicalism.” In both cases, the consciousness explanatory gap is a good way to argue against physicalism. (shrink)

I defend the actualist higher-order thought theory against four objections. The first objection contends that the theory is circular. The second one contends that the theory is unable to account for the alleged epistemic position we are in with respect to our own conscious mental states. The third one contends that the theory is unable to account for the evidence we have for the proposition that all conscious mental states are represented. The fourth one contends that the theory does not (...) accommodate the intimacy we have with our own conscious mental states. To some extent, my defense will be heterodox, in the sense that I will show that some objections are satisfactorily answerable even if we concede to the objectors a point that higher-order theorists do not seem to be willing to concede, that is, that the theory is the result of conceptual analysis.

Self-evidencing describes the purported predictive processing of all self-organising systems, whether conscious or not. Self-evidencing in itself is therefore not sufficient for consciousness. Different systems may however be capable of self-evidencing in different, specific and distinct ways. Some of these ways of self-evidencing can be matched up with, and explain, several properties of consciousness. This carves out a distinction in nature between those systems that are conscious, as described by these properties, and those that are not. This approach throws new (...) light on phenomenology, and suggests that some self-evidencing may be characteristic of consciousness. (shrink)

In this chapter, I revisit the issue of the explanatory gap that is supposed to open when considering identity statements between physical and mental phenomena. I show that the question asked in the original formulation of the explanatory gap was this: ʻwhy this phenomenal character, rather than any other, is attached to this physiological process?ʼ I argue that this question can be answered, because there is a natural fit between the phenomenal character of experiences and their functional roles. For example, (...) pains feel inherently unpleasant, and that explains why they cause avoidance behaviour, and the felt location and intensity of pain indicates the location and extent of damage to the body. I discuss some other possible gaps in our understanding the relationship between the mental and the physical, and conclude that the fit between functional role and phenomenal character goes a long way, though probably not the whole way, to closing the explanatory gap.

It is common belief that semantic properties supervene on non-semantic properties: no two possible worlds can be non-semantic duplicates and fail to be semantic duplicates. The view enjoys somewhat of an orthodoxy status in contemporary philosophy of language and metaphysics, and is often assumed without argument. Yet, work by Stephen Kearns and Ofra Magidor has claimed that it is vulnerable to a variant of the classical arguments against the supervenience of the phenomenal on the physical. This paper does three things: (...) it clarifies what semantic supervenience is about, it responds to the objections that have been leveled against it, and provides a new battery of arguments in its favor. I argue that the thesis of semantic supervenience is safe from classical anti-supervenience arguments, and show that its rejection generates unwelcome consequences. I conclude that there are substantial reasons to embrace the received wisdom: semantic properties supervene. (shrink)

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.

This essay is an introduction to the Routledge Handbook of Philosophy of Colour. Why has the examination of many different aspects of colour been a prominent feature in philosophy, to such an extent that the topic is worthy of a handbook? Here are two related answers. First, colours are exceedingly familiar, seemingly simple features that become enigmatic under scrutiny, and they are difficult to capture in any familiar-sounding, unsophisticated theory. Second, through colour one can confront various problems that span the (...) breadth of philosophy, including problems pertaining to perception, the mind-body relation, the nature of science, scepticism, vagueness, meta-ethics, and aesthetics. In this introduction we elaborate and guide the reader to the essays in the rest of this volume. (shrink)

This paper examines an argument by Schaffer (2017) that aims to prove how, contrary to what many philosophers hold, there is no special explanatory gap occurring in the connection between the physical and the phenomenal. This is because a gap of the same kind can be found in every connection between a more fundamental and a less fundamental level of reality. These gaps lurk everywhere in nature. For Schaffer, they can be bridged by means of substantive metaphysical principles such as (...) grounding principles. He thus puts forward a version of grounding-based physicalism, which is supposed to provide this kind of substantive bridge principle. My main contention is as follows: even if Schaffer’s argument indeed proves the existence of a gap in every connection between fundamental and derivative entities, and such gaps can be bridged by means of grounding principles, a different gap remains open in the psycho-physical connection.

The Humility Thesis is a persistent thesis in contemporary metaphysics. It is known by a variety of names, including, but not limited to, Humility, Intrinsic Humility, Kantian Humility, Kantian Physicalism, Intrinsic Ignorance, Categorical Ignorance, Irremediable Ignorance, and Noumenalism. According to the thesis, we human beings, and any knowers that share our general ways of knowing, are irremediably ignorant of a certain class of properties that are intrinsic to material entities … Continue reading Humility Regarding Intrinsic Properties →.

Several philosophers claim that a mental state is phenomenally conscious only if it exhibits so-called for-me-ness, or subjective character, i.e., the fact that there is something it is like to be in a conscious state not just for everyone but only for the subject who undergoes it. Consequently, they stress, a proper explanation of consciousness requires to address the question of what the nature of for-me-ness is. This question forms what I call the problem of for-me-ness. Although the debate on (...) the problem of for-me-ness has assumed a centre stage within philosophy of consciousness, relatively scant attention has been paid to systematize it. In this paper, I propose to fill this gap by developing a taxonomy of the existing responses to the problem at stake. I start by claiming that for-me-ness—the phenomenon to be explained—is best thought of as a minimal form of self-consciousness. Answering the problem of for-me-ness, hence, means to provide an account of the metaphysical structure of such a phenomenon. Next, I claim that the nature and the structure of minimal self-consciousness can be established by considering five conceptual distinctions. Based on such distinctions, finally, I classify the existing responses to the problem of for-me-ness into five positions. Scholars interested in the debate at issue should find this taxonomy useful not only to recognise and assess the core theses of the existing answer to the problem of for-me-ness but also to develop their own response.

In this paper, I argue for a new solution to Mary’s puzzle in Jackson’s famous knowledge argument. We are told that imprisoned Mary knows all facts or truths about color and color vision. On her release, she learns something new according to B-type of materialism and according to property dualism. I argue that this cognitive improvement can only be accounted for in terms of what Schellenberg has recently called “capacitism,” namely the claim that that experience is constitutively a matter of (...) discriminating and singling out particulars by employing perceptual capacities. Of course, I am not claiming that knowing the phenomenal character is simply the possession of abilities, let alone that the phenomenal character is a sort of know-how. That is why my claim is not affiliated with Lewis and Nemirow's ability hypothesis position. I take for granted here a sort of property-representationalism, according to which the phenomenal character of experience supervenes on the cluster of properties that the respective experiences represent. On her release, Mary acquires those perceptual abilities on the basis of which she learns to discriminate all shades of color. And after applying her old physical concept RED to the shade of red, she comes to know what it is like to experience red (propositional knowledge). (shrink)

When you and I share an experience, each of us lives through a we-experience. The paper claims that we-experiences have unique phenomenality and structure. First, we-experiences’ phenomenality is characterised by the fact that they feel like ours to their subject. This specific phenomenality is contended to derive from the way these experiences self-represent: a we-experience exemplifies us-ness or togetherness because it self-represents as mine qua ours. Second, living through a we-experience together with somebody else is not to have this experience (...) in parallel with the experience of the other. Rather, the paper argues that a we-experience is partly co-constituted by the experience of the other. After offering an account of the phenomenality and constitution of we-experiences, which traces these two elements back to the subject’s self-understanding as a group member, the paper argues for the claim that an experience’s for-us-ness is committal to this experience being co-constituted by another we-experience.

Russellian monism – an influential doctrine proposed by Russell (1927/1992) – is roughly the view that the natural sciences can only ever tell us about the causal, dispositional, and structural properties of physical entities and not about their categorical properties, and, moreover, that our qualia are constituted by categorical properties. Recently, Stoljar (2001a, 2001b), Strawson (2008), Montero (2010, 2015), Alter and Nagasawa (2012), and Chalmers (2015) have attempted to develop this doctrine into a version of physicalism. Russellian monism faces the (...) so-called combination problem, according to which it is difficult to see how categorical properties could collectively constitute qualia. In this paper, I suggest that there is an insufficiently discussed aspect of the combination problem which I call the difference-maker problem. Taking the difference-maker problem into account, I argue that the combination problem – whether or not it can be solved – results in a dilemma for the project of developing Russellian physicalism. That is, Russellian monism is either physicalistically unacceptable or it is implausible; hence, Russellian monism and physicalism are incompatible. (shrink)

This chapter analyzes the relation between brain sciences and philosophy of mind, in order to clarify in what ways philosophy can contribute to neuroscience and neuroscience can contribute to philosophy. Especially since the 1980s and the emergence of “neurophilosophy”, more and more philosophers have been bringing home morals from neuroscience to settle philosophical issues. I mention examples from the problem of consciousness, philosophy of perception and the problem of free will, and I argue that such attempts are not successful in (...) trying to settle questions like whether psychology can be reduced to neuroscience, whether we see the external world directly in perception, or whether we have free will. The failure results from an ability of the philosophical questions to evade the data. What makes these questions persisting philosophical questions is precisely that there is no way to settle them through empirical evidence, as they are conceptual questions and their solution lies in conceptual analysis.

Chalmers’ meta-problem of consciousness is the problem of explaining “problem reports”; i.e. reports to the effect that phenomenal consciousness has the various features that give rise to the hard problem. Chalmers (Journal of Consciousness Studies 25: 6–61, 2018, 8) suggests that solving the meta-problem will likely “shed significant light on the hard problem.” Against this, I argue that work on the meta-problem will likely fail to make the hard problem any easier. For each of the main stances on the hard (...) problem can provide an account of problem reports, and we have no way of deciding which of these accounts gives the correct explanation of an individual’s problem reports without presupposing a stance on the hard problem. We thus cannot determine which of the available solutions to the meta-problem is correct without having already solved the hard problem. (shrink)

A group of philosophers suggests that a sense of mineness intrinsically contained in the phenomenal structure of all conscious experiences is a necessary condition for a subject to become aware of himself as the subject of his experiences i.e. self-awareness. On this view, consciousness necessarily entails phenomenal self-awareness. This paper argues that cases of delusions of thought insertion undermine this claim and that such a phenomenal feature plays little role in accounting for the most minimal type of self-awareness entailed by (...) phenomenal consciousness. First, I clarify the main view endorsing this claim i.e. the Self-Presentational View of Consciousness and formulate the challenge from thought insertion. After, I offer a systematic evaluation of all the strategies used by the advocates of this view to deal with this challenge. Finally, I conclude that most of these strategies are unsatisfactory for they rest in unwarranted premises, imprecisions about the agentive nature of cognitive experiences, and especially, lack of distinction between the different ways in which subjects can become aware of their own thoughts.

Various psychopathologies of self-awareness, such as somatoparaphrenia and thought insertion in schizophrenia, might seem to threaten the viability of the higher-order thought (HOT) theory of consciousness since it requires a HOT about one’s own mental state to accompany every conscious state. The HOT theory of consciousness says that what makes a mental state a conscious mental state is that there is a HOT to the effect that “I am in mental state M.” I have argued in previous work that a (...) HOT theorist can adequately respond to this concern with respect to somatoparaphrenia and thought insertion. There is also Cotard syndrome which is a rare neuropsychiatric disorder in which people hold the delusional belief that they are dead, do not exist, or have lost their blood or internal organs. In this paper, I argue that HOT theory has nothing to fear from it either and can consistently account for what happens in such unusual cases. I analyze Cotard syndrome in light of my previous discussion of somatoparaphrenia and thought insertion, and argue that HOT theory can provide a somewhat analogous account without the worry of inconsistency. It is crucial to recognize that there are multiple “self-concepts” and levels of HOTs which can help to provide a more nuanced explanation. With regard to the connection between consciousness and self-consciousness, it is proposed that Cotard patients are indeed capable of having some “I-thoughts” about their bodies and mental states.

One of David Rosenthal’s many important contributions to the philosophy of mind was his clear and unshirking account of introspection. Here we argue that while there is a kind of introspection (we call it “reflective introspection”) that Rosenthal’s account may be structurally fit to accommodate, there is also a second kind (“primitive introspection”) that his account cannot recover. We introduce Rosenthal’s account of introspection in §1, present the case for the psychological reality of primitive introspection in §2, and argue that (...) Rosenthal’s account lacks the resources to accommodate it in §3. (shrink)

In this chapter, Pautz raises a puzzle about spatial experience for phenomenal internalists like Ned Block. If an accidental, lifelong brain-in-the-void (BIV) should have all the same experiences as you, it would have an experience as of items having various shapes, and be able to acquire concepts of those shapes, despite being cut off from real things with the shapes. Internalists cannot explain this by saying that BIV is presented with Peacocke-style visual field regions having various shapes, because these would (...) have to be non-physical sense data. They might instead explain this by saying that BIV “phenomenally represents” various shape properties. But since BIV lacks any interesting physical relations to shapes, this would imply that phenomenally representation is an irreducible relation. (shrink)

Illusionists claim that phenomenal consciousness does not exist, but merely seems to exist. Most debates concerning illusionism focus on whether or not it is true—whether phenomenal consciousness really is an illusion. Here I want to tackle a different question: assuming illusionism is true, what kind of illusion is the illusion of phenomenality? Is it a “rich” illusion—the cognitively impenetrable activation of an incorrect representation—or a “sparse” illusion—the cognitively impenetrable activation of an incomplete representation, which leads to drawing incorrect judgments? I (...) present this distinction and I classify the most influential illusionist theories along this line of divide. I then offer an argument against the accounts of the illusion of phenomenality in terms of sparse illusion. (shrink)

In the philosophy of mind, revelation is the claim that the nature of qualia is revealed in phenomenal experience. In the literature, revelation is often thought of as intuitive but in tension with physicalism. While mentions of revelation are frequent, there is room for further discussion of how precisely to formulate the thesis of revelation and what it exactly amounts to. Drawing on the work of David Lewis, this paper provides a detailed discussion on how the thesis of revelation, as (...) well as its incompatibility with physicalism, is to be understood. (shrink)

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

Illusionism about phenomenal consciousness is the thesis that phenomenal consciousness does not exist, even though it seems to exist. This thesis is widely judged to be uniquely counterintuitive: the idea that consciousness is an illusion strikes most people as absurd, and seems almost impossible to contemplate in earnest. Defenders of illusionism should be able to explain the apparent absurdity of their own thesis, within their own framework. However, this is no trivial task: arguably, none of the illusionist theories currently on (...) the market is able to do this. I present a new theory of phenomenal introspection and argue that it might deal with the task at hand. (shrink)

Over the past three decades, psychological distress has increasingly come to be explained in neurobiological terms by both mental health professionals and the general public. Disorders like major depression are now most commonly understood to be symptoms of some, as of yet unidentified, biochemical or neurological disturbance in the brain and thus treatment often focuses exclusively on the pharmacological without being inclusive of psychotherapeutic options. This etiological claim rests on the same assumptions as does reductive physicalism within philosophy. Understanding this (...) paradigm, as it appears in philosophy, can potentially play an important role in informing the debate over how best to understand and ease mental suffering. In particular, by critiquing reductive physicalism and identifying the importance of nuanced understandings of complex phenomena, philosophers can aid mental health practitioners and policy makers in developing more robust, holistic approaches to mental healthcare.

Many philosophers have tried to defend physicalism concerning phenomenal consciousness, by explaining dualist intuitions within a purely physicalist framework. One of the most common strategies to do so consists in interpreting the alleged “explanatory gap” between phenomenal states and physical states as resulting from a fallacy, or a cognitive illusion. In this paper, I argue that the explanatory gap does not rest on a fallacy or a cognitive illusion. This does not imply the falsity of physicalism, but it has consequences (...) on the kind of physicalism we should embrace. (shrink)

Subjectivity is that feature of consciousness whereby there is something it is like for a subject to undergo an experience. One persistent challenge in the study of consciousness is to explain how subjectivity relates to, or arises from, purely physical brain processes. But, in order to address this challenge, it seems we must have a clear explanation of what subjectivity is in the first place. This has proven challenging in its own right. For the nature of subjectivity itself seems to (...) resist straightforward characterization. In this paper, I won't address how subjectivity relates to the physical. Instead, I'll address subjectivity itself. I'll do this by introducing and defending a model of subjectivity based on self-acquaintance. My model does not purport to reduce, eliminate, or naturalize subjectivity, but it does make subjectivity more tractable, less paradoxical, and perhaps less dubious to those averse to obscurity.

I investigate the status of subjectivity in Integrated Information Theory. This leads me to examine if Integrated Information Theory can answer the hard problem of consciousness. On itself, Integrated Information Theory does not seem to constitute an answer to the hard problem, but could be combined with panpsychism to yield a more satisfying theory of consciousness. I will show, that even if Integrated Information Theory employs the metaphysical machinery of panpsychism, Integrated Information would still suffer from a different problem, not (...) being able to account for the subjective character of consciousness.

The Significance Argument (SA) for the irreducibility of consciousness is based on a series of new puzzle-cases that I call multiple candidate cases. In these cases, there is a multiplicity of physical-functional properties or relations that are candidates to be identified with the sensible qualities and our consciousness of them, where those candidates are not significantly different. I will argue that these cases show that reductive materialists cannot accommodate the various ways in which consciousness is significant and must allow massive (...) vagueness in conscious experience. I also will argue that a nonreductive theory of the conscious-of relation can easily provide a very satisfying, unified explanation of the ways in which this relation is significant. (shrink)

There is converging evidence that high doses of hallucinogenic drugs can produce significant alterations of self-experience, described as the dissolution of the sense of self and the loss of boundaries between self and world. This article discusses the relevance of this phenomenon, known as “drug-induced ego dissolution (DIED)”, for cognitive neuroscience, psychology and philosophy of mind. Data from self-report questionnaires suggest that three neuropharmacological classes of drugs can induce ego dissolution: classical psychedelics, dissociative anesthetics and agonists of the kappa opioid (...) receptor (KOR). While these substances act on different neurotransmitter receptors, they all produce strong subjective effects that can be compared to the symptoms of acute psychosis, including ego dissolution. It has been suggested that neuroimaging of DIED can indirectly shed light on the neural correlates of the self. While this line of inquiry is promising, its results must be interpreted with caution. First, neural correlates of ego dissolution might reveal the necessary neurophysiological conditions for the maintenance of the sense of self, but it is more doubtful that this method can reveal its minimally sufficient conditions. Second, it is necessary to define the relevant notion of self at play in the phenomenon of DIED. This article suggests that DIED consists in the disruption of subpersonal processes underlying the “minimal” or “embodied” self, i.e., the basic experience of being a self rooted in multimodal integration of self-related stimuli. This hypothesis is consistent with Bayesian models of phenomenal selfhood, according to which the subjective structure of conscious experience ultimately results from the optimization of predictions in perception and action. Finally, it is argued that DIED is also of particular interest for philosophy of mind. On the one hand, it challenges theories according to which consciousness always involves self-awareness. On the other hand, it suggests that ordinary conscious experience might involve a minimal kind of self-awareness rooted in multisensory processing, which is what appears to fade away during DIED.

Quality-space theory (QST) explains the nature of the mental qualities distinctive of perceptual states by appeal to their role in perceiving. QST is typically described in terms of the mental qualities that pertain to color. Here we apply QST to the olfactory modalities. Olfaction is in various respects more complex than vision, and so provides a useful test case for QST. To determine whether QST can deal with the challenges olfaction presents, we show how a quality space (QS) could be (...) constructed relying on olfactory perceptible properties and the olfactory mental qualities then defined by appeal to that QS of olfactory perceptible properties. We also consider how to delimit the olfactory QS from other modalities. We further apply QST to the role that experience plays in refining our olfactory discriminative abilities and the occurrence of olfactory mental qualities in non-conscious olfactory states. QST is shown to be fully applicable to and useful for understanding the complex domain of olfaction. (shrink)

One of the leading concerns animating current philosophy of mind is that, no matter how good a scientific account is, it will leave out what its like to be conscious. The challenge has thus been to study or at least explain away that qualitative dimension. Pursuant with that aim, I investigate how philosophy of signs in the Peircean tradition can positively reshape ongoing debates. Specifically, I think the account of iconic or similarity-based reference we find in semiotic theory offers a (...) more promising variant of the phenomenal concept strategy. Philosophers who endorse this strategy think that the difficulties we have fitting conscious qualia into a scientific picture may owe to the peculiar nature of indexical concepts. They point to the fact that, when we try to convey the feel of our experiences, we employ context-dependent gestures and/or utterances that are indexed to perspectives unique to each person. However, according to the theory I defend, there are three ways signs can refer, namely by convention, causal contact, and similarity. Since similarity is not reducible to proximity, I argue that a theory of reference that turns on shared quality can bypass some of the implausible consequences that plague indexical accounts. In the first chapter, I describe the apparatus needed to make sense of this claim. In the second chapter, I present my account of iconic reference. In the third chapter, I justify my reliance on a distinction that is less than real yet more than nominal. In the fourth chapter, I sketch a trinitarian metaphysics well-suited to house the foregoing account of qualia. (shrink)

I will argue that accounts of mineness and pre-reflective self-awareness can be helpful to panpsychists in solving the combination problems. A common strategy in answering the subject combination problem in panpsychism is to deflate the subject, eliminating or reducing subjects to experience. Many modern panpsychist theories are deflationist or endorse deflationist accounts of subjects, such as Parfit’s reductionism of personal identity and G. Strawson’s identity view. To see if there can be deflation we need to understand what the subject/self is. (...) One aspect of consciousness left unexplored and unappreciated by panpsychist theories is pre-reflective self-consciousness/self-awareness. Theories of the self, inspired by phenomenology, that are serious about subjectivity, could be of use in arguing against the deflationary reductionism of the experiencing subject. These theories show that there is more to the subject of experience than just its experiences (qualities). Even without arguing for any precise account of the nature of the self, it can be shown what phenomenology of subjective character of consciousness and pre-reflective self-awareness contributes to the combination problem debate.

Illusionism about consciousness is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Embracing illusionism presents the theoretical advantage that one does not need to explain how consciousness arises from purely physical brains anymore, but only to explain why consciousness seems to exist while it does not. As Keith Frankish puts it, illusionism replaces the “hard problem of consciousness” with the “illusion problem.” However, a satisfying version of illusionism has to explain not only why the illusion (...) of consciousness arises, but also why it arises with its particular strength: Notably, why we are so deeply reluctant to recognize the illusory nature of consciousness. Explaining our strong intuitive resistance to illusionism means solving what I call the “illusion meta-problem,” which I think is a part of the illusion problem. In this paper, I argue that current versions of illusionism are unable to solve the illusion meta-problem. I focus on two of the most promising recent illusionist theories of consciousness, and I show why they fail to explain the peculiar reluctance we encounter whenever we try to accept that consciousness is an illusion.

This dissertation defends the reliability of first-person methods for studying consciousness, and applies first-person experiments to two philosophical problems: the experience of size and of the self. In chapter 1, I discuss the motivations for taking a first-person approach to consciousness, the background assumptions of the dissertation and some methodological preliminaries. In chapter 2, I address the claim that phenomenal judgements are far less reliable than perceptual judgements (Schwitzgebel, 2011). I argue that the main errors and limitations in making phenomenal (...) judgements are due to domain-general factors, which are shared in the formation of perceptual judgements. Phenomenal judgements may still be statistically less reliable than perceptual judgements, though I provide reasons for thinking that Schwitzgebel (2011) overstates the case for statistical unreliability. I also provide criteria for distinguishing between reliable and unreliable phenomenal judgements, hence defending phenomenal judgements against general introspective scepticism. Having identified the main errors in making phenomenal judgements, in chapter 3, I discuss how first-person experiments can be used to control for these errors. I provide examples, and discuss how they overcome attentional and conceptual errors, minimise biases, and exhibit high intersubjective reliability. In chapter 4, I investigate size experience. I use first-person experiments and empirical findings to argue that distant things looking smaller cannot be explained as an awareness of instantiated objective properties (visual angle or retinal image size). I also discuss how an awareness of uninstantiated objective properties cannot adequately account for the phenomenal character of size experience. This provides support for a subjectivist account of variance in size experience. In chapter 5, I investigate the sense of self. I distinguish between a weak sense of self (for-me-ness) and a strong sense of self in which there is a polarity between subject and object. I use first-person experiments from Douglas Harding to demonstrate an explicit strong sense of self, specifically when I point at where others see my face. I also argue that this sense of self is not explained by inference, thoughts, feelings, imagination nor the viewpoint. Rather, it is part of the structure of experience that I seem to be looking from here. Even if there is a sense of self, there may be no self. The question of chapter 6 is whether there can be a direct experience of the self. I argue that to function as a bearer of experience the subject must be single and lack sensory qualities in itself. I use Harding’s first-person experiments to investigate the visual gap where I cannot see my head. I argue that it conforms to the above criteria, and hence is a candidate for being the subject. This finding, in conjunction with the fact that I seem to be looking from the same location, provides prima facie evidence for the reality of the subject. I hold then that contrary to Hume and most philosophers since, that there can be a direct self-experience, if one knows which direction to attend. (shrink)
