There are two different varieties of question concerning the unity of consciousness: questions about unity at a time, and unity over time. A recent trend in the debate about unity has been to attempt to provide a ‘generalized’ account that purports to solve both problems in the same way. This attempt can be seen in the accounts of Barry Dainton and Michael Tye. In this paper, I argue that there are crucial differences between unity over time and unity at a (...) time that make it impossible to provide a generalized account of unity. The source of these crucial differences is the phenomenon of the ‘continuity of consciousness’. I argue that accounts of unity over time have to provide an account of this continuity, and that there is no phenomenon analogous to continuity in the case of unity at a time. Attention to the continuity of consciousness reveals crucial structural differences between the two varieties of unity. These structural differences make it impossible to provide a generalized account of unity. I show that the problems faced by Dainton’s and Tye’s accounts in the light of the structural differences make their accounts of unity appear far less appealing than they might initially have looked. I conclude by noting that, in the light of the important differences between the two varieties of unity, it is a mistake to attempt to model accounts of unity over time on accounts of unity at a time.

The Nagel inspired “something-it-is-like” conception of conscious experience remains a dominant approach in philosophy. In this paper I criticize a prevalent philosophical construal of SIL consciousness, one that understands SIL as a property of mental states rather than entities as a whole. I argue against thinking of SIL as a property of states, showing how such a view is in fact prevalent, under-warranted, and philosophically pernicious in that it often leads to an implausible reduction of conscious experience to qualia. I (...) then develop a holistic conception of SIL for entities and argue that it has at least equal pre-empirical warrant, is more conservative philosophically in that it decides less from the a priori “armchair,” and enjoys a fruitful two-way relationship with empirical work.

The phenomenology of the unity of consciousness can be analyzed in terms of perceptual spatial and object unity. Subject unity—what we commonly understand by “the unity of consciousness”—has no attendant phenomenology. The further, non-phenomenological, effects of unity can be analyzed in terms of the functional notion of access unity. The unity of consciousness in general can therefore be analyzed in terms of access unity. As a consequence, we can avoid the theoretical introduction of problematic notions such as subsumptive or phenomenal (...) unity. (shrink)

Barry Dainton has developed a sophisticated version of the bundle theory of the subject of experiences. I shall focus on three claims Dainton makes: the identity-conditions of subjects can be specified in terms of capacities to produce experiences; the identity-conditions of token capacities are not determined by their subjects; and a subject is nothing over and above a bundle of such capacities. I shall argue that Dainton’s key notion of co-consciousness, a primitive relation of experienced togetherness, presupposes a subject common (...) to each of the experiences which are experienced together. Therefore, co-consciousness cannot be used to state the identity-conditions of subjects in a non-circular manner. I shall also argue that none of the different options Dainton offers for specifying the identity-conditions of token experiential capacities independently of their subjects are successful. I shall then outline a way in which this can be done, but argue that it undermines the claim that a subject is nothing over and above a bundle of such capacities. (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.

Panpsychism has often been motivated on the grounds that any attempt to account for experience and consciousness in organisms in purely physical, nonexperiential terms faces severe difficulties. The “combination problem” charges that attributing phenomenal properties to the basic constituents of organisms, as panpsychism proposes, likewise fails to provide a satisfactory basis for experience in humans and other organisms. This paper evaluates a recent attempt to understand, and solve, the combination problem. This approach, due to Sam Coleman, is premised on a (...) distinction between mere aggregates and genuine unities, and the purported inability of subjects to constitute a unity. In response, I first argue that it may not be incumbent upon the panpsychist to explain how microphenomenal properties could constitute a unity in the way that Coleman supposes. I then argue that even if such a burden does fall on the panpsychist, it is far from clear that a plurality subjects cannot constitute such a unity. Finally, I argue that if one adopts a functionalist account of macrosubjects, as Coleman does, there is little reason to think that a plurality of subjects could not constitute a macrosubject. In these ways, I argue that the force of the combination problem does not turn on whether microphenomenal properties require minds or subjects that have them. (shrink)

We explore the integrated structure of consciousness by examining the “phenomenological axioms” of the “integrated information theory of consciousness ” from the perspective of Husserlian phenomenology. After clarifying the notion of phenomenological axioms by drawing on resources from Edmund Husserl and Maurice Merleau-Ponty, we develop a critique of the integration axiom by drawing on phenomenological analyses developed by Aron Gurwitsch and Merleau-Ponty. This axiom is ambiguous. It can be read either atomistically as claiming that the phenomenal content of conscious experience (...) is an integrated complex and holistically as claiming that it is an integrated Gestalt. We argue that the latter reading provides a better characterization of the internal structure of the phenomenal content. Furthermore, the integrated structure of consciousness is not confined to the phenomenal content, but it also extends into the subjective attitude. Subjective attitudes and phenomenal contents are interdependent constituents that jointly make up conscious experiences. This implies a novel theoretical challenge to the scientific component of IIT, which is to explain how to accommodate the subjective dimension of consciousness into its explanatory scope. IIT can respond in a few different ways, but most importantly, it cannot just ignore it once and for all. As one possible way to address the challenge, we propose introducing a novel construct, noetic complex, to develop a fine-grained model of the neural underpinning of consciousness. (shrink)

Growing concern with the panpsychist's ostensive inability to solve the ‘combination problem’ has led some authors to adopt a view titled ‘Cosmopsychism’. This position turns panpsychism on its head: rather than many tiny atomic minds, there is instead one cosmos-sized mind. It is supposed that this view voids the combination problem, however I argue that it does not. I argue that there is a ‘de-combination problem’ facing the cosmopsychist, which is equivalent to the combination problem as they are both concerned (...) with subjects being proper parts of other subjects. I then propose two methods for both theorists to avoid the problem of subject-subject proper parthood relations: a distinction between absolute and relative phenomenal unity, and a modification of the essential nature of subjects. Of these two options, I find the latter option wanting and propose that the first should be adopted. (shrink)

The goal of this paper is to raise a few questions about Bayne s mereological account of the unity of consciousness. In Section 1, I raise a few clarificatory questions about the account and the thesis that consciousness is necessarily unified. In Sections 2 and 3, I offer an alternative view of unity of consciousness and contrast it with Bayne's view. I call this view the connectivity account. These sections prepare the ground for the main question of this article: why (...) should we prefer Bayne's mereological view to the connectivity view? (shrink)

The metaphysical vision of Advaita Vedānta has been making its way into some corners of Western analytic philosophy, and has especially garnered attention among those philosophers who are seeking to develop metaphysical systems in opposition to both reductionist materialism and dualism. Given Vedānta’s monistic view of consciousness, it might seem natural to put Vedānta in dialogue with the growing position of panpsychism which, although not fully monistic, similarly takes mind to be a fundamental feature of reality. This paper will evaluate (...) to what extent Śaṅkara’s monism can bypass the most pressing issues facing panpsychism, namely combination and individuation problems. As will be seen in this paper, while Advaita Vedānta is able to avoid some of the panpsychist problems, it struggles ultimately to ontologically ground illusion in a coherent manner. As a result, a conclusion of this paper is that although Śaṅkara’s vision offers a promising route for those philosophers who take consciousness to be fundamental – including panpsychists – it cannot be uncritically adopted due to the problem of grounding Illusion.

I give an account of the difference between "Holistic" and "Atomistic" views of conscious experience. On the Holistic view, we enjoy a unified "field" of awareness, whose parts are mere modifications of the whole, and therefore owe their existence to the whole. There is some tendency to saddle those who reject the Holistic field model with a (perhaps) implausible "building block" view. I distinguish a number of different theses about the parts of an experience that are suggested by the "building (...) block" metaphor, but which can be rejected by those who also reject the holistic field view.

Disputes about what is phenomenologically manifest in conscious experience have a way of leading to deadlocks with remarkable immediacy. Disputants reach the foot-stomping stage of the dialectic more or less right after declaring their discordant views. It is this fact, I believe, that leads some to heterophenomenology and the like attempts to found Consciousness Studies on purely third-person grounds. In this paper, I explore the other possible reaction to this fact, namely, the articulation of methods for addressing phenomenological disputes. I (...) suggest two viable methods, of complementary value, which I call “the method of contrast” and “the method of knowability.”. (shrink)

When a person has an intuition, it seems to her that things are certain ways; to many it seems that torturing the innocent for fun is wrong, for example. When a person has an intuition, there is also something particular it is like to be her: intuitions have a characteristic phenomenal character. This article asks how the phenomenal character of intuition is related to two core core questions in the philosophy of intuition, namely: Is intuition a source of justification and (...) knowledge? and What are intuitions?. (shrink)

Propositional attitudes are often classified as non-phenomenal mental states. I argue that there is no good reason for doing so. The unwillingness to view propositional attitudes as being essentially phenomenal stems from a biased notion of phenomenality, from not paying sufficient attention to the idioms in which propositional attitudes are usually reported, from overlooking the considerable degree to which different intentional modes can be said to be phenomenologically continuous, and from not considering the possibility that propositional attitudes may be transparent, (...) just like sensations and emotions are commonly held to be: there may be no appropriate way of describing their phenomenal character apart from describing the properties and objects they represent. (shrink)

Two debates loom large in current discussions on phenomenal consciousness. One debate concerns the relation between phenomenal character and representational content. Representationalism affirms, whereas “content separatism” denies, that phenomenal character is exhausted by representational content. Another debate concerns the relation between phenomenal consciousness and cognitive access. “Access separatism” affirms, whereas, e.g., the global workspace model denies, that there are phenomenally conscious states that are not cognitively accessed. I will argue that the two separatist views are related. Access separatism supports content (...) separatism by undermining the most prominent sort of arguments in favor of representationalism, namely ones that appeal to the phenomenology of perceptual experiences.

In this paper I would like to defend three interconnected claims. The first stems from the fact that the definition of substance dualism recently proposed by Dean Zimmerman needs some essential adjustments in order to capture the genuine spirit of the doctrine. In this paper I will formulate the conditions for genuine substance dualism, as distinct from quasi-dualisms, and provide a definition for genuine substance dualism that I consider more appropriate than Zimmerman’s. The second is that none of the currently (...) proposed forms of substance dualism are able to provide a satisfactory account of conscious subjectivity. To support this claim I present two arguments, the first against Cartesian Dualism, the other against Emergent Dualism. The third, I believe, derives from the two just mentioned: if the dualistic arguments against the ability of physicalist theories to provide a sound account of the unity of the subject of consciousness are persuasive enough, then, in order to acquire a more adequate account of the unity of the conscious subject, we will have to look more closely at such forms of quasi-dualism as spiritualism or a broadly Aristotelian view of human persons.

Haptic touch is an inherently active and exploratory form of perception, involving both coordinated movements and an array of distinct sensory receptors in the skin. For this reason, some have claimed that haptic touch is not a single sense, but rather a multisensory collection of distinct sensory systems. Though this claim is often made, it relies on what I regard as a confused conception of multisensory interaction. In its place, I develop a nuanced hierarchy of multisensory involvement. According to this (...) hierarchy, touch turns out to be a single modality in that its various receptors assign their features to the same tangible objects. When we grasp an object a range of distinct properties?shape, warmth, heft, texture, etc.?are all felt to belong to the object, just as different visual properties are associated with a visual object. Paradigm multisensory experiences, on the other hand, involve associations between distinct perceptual experiences, as when the way something looks affects the way something sounds. Thus despite its functional and physiological diversity, haptic touch can be regarded as a single sense. (shrink)

Buddhism teaches that ‘self’ as a substantial, enduring entity is an illusion. But for self to be an illusion there must be something in our experience that is misinterpreted as self. What is this? The notion of an experiential self plays an important role in phenomenological investigations of conscious experience. Does the illusion of self consist in mistaking a purely experiential self for a substantial self? I argue against this and locate the source of the illusion in time-consciousness. It is (...) the essence of consciousness to flow, but the flow of consciousness presupposes an experiential present. The experiential present — an abiding sense of ‘now’ — is the dimension through which experiences are experienced as streaming. It is this, I argue, that is misinterpreted as an enduring self. I support my account by arguing that the synchronic and diachronic unity of consciousness can be accounted for in terms of impersonal, temporal experience, and that conceiving of consciousness as the presence-dimension rather than as the I-dimension affords a solution to the brain-bisection puzzle. (shrink)

In this article I distinguish the notion of there being something it is like to be a certain kind of creature from that of there being something it is like to have a certain kind of experience. Work on consciousness has typically dealt with the latter while employing the language of the former. I propose several ways of analyzing what it is like to be a certain kind of creature and find problems with them all. The upshot is that even (...) if there is something it is like to have certain kinds of experience, it does not follow that there is anything it is like to be a certain kind of creature. Skepticism about the existence of something that it is like to be an F is recommended. (shrink)

When it comes to personal identity, two approaches have long ruled the roost. The first is the psychological approach, which has it that our persistence through time consists in the continuance of certain of our psychological traits, such as our memories, beliefs, desires, or personality. The second is the biological approach, according to which personal persistence consists in continuity in our physical or biological makeup. Amid the bipartite reign of these approaches, a third contender has emerged: the phenomenal approach. On (...) this approach, personal persistence consists in continuity in phenomenal consciousness or the capacity for phenomenal consciousness. In this paper I will introduce and defend a new argument for the phenomenal approach. In the process, I will argue against the psychological and biological approaches. I will also address some lingering questions and outline further ways to develop the phenomenal approach. (shrink)

According to the Phenomenal Unity Thesis (“PUT”) – most prominently defended by Tim Bayne and David Chalmers – necessarily, any set of phenomenal states of a subject at a time is phenomenally unified. The standard formulation of this thesis is unacceptably vague because it does not specify what it is to be a subject. In this paper, I first consider possible meanings for ‘subject’ as used in PUT and argue that every plausible candidate definition renders the thesis trivially true. I (...) consider and reject Tim Bayne’s proposal that ‘subject’ means ‘human being’. Then I argue, contra Bayne and Chalmers, that PUT is not incompatible with any major theory of consciousness, and contra Michael Tye, that split-brain patients do not provide evidence against PUT. I close by considering some nontrivial alternatives to PUT. (shrink)

Does consciousness collapse the quantum wave function? This idea was taken seriously by John von Neumann and Eugene Wigner but is now widely dismissed. We develop the idea by combining a mathematical theory of consciousness (integrated information theory) with an account of quantum collapse dynamics (continuous spontaneous localization). Simple versions of the theory are falsified by the quantum Zeno effect, but more complex versions remain compatible with empirical evidence. In principle, versions of the theory can be tested by experiments with (...) quantum computers. The upshot is not that consciousness-collapse interpretations are clearly correct, but that there is a research program here worth exploring. (shrink)

I argue that it is metaphysically necessary that: (i) every fundamental entity is conscious, and (ii) every fundamental property is a phenomenal property.

Even thirty years after Thomas Morris wrote The Logic of God Incarnate, there are some claims that Morris makes that require examination in analytic Christology. One of those claims is a concession that Morris gives to modalists near the end of the book, where he says that the two-minds view he has defended can be used to provide a consistent modalistic understanding of Jesus’s prayer life. This view, he says, blocks the inference from the fact that Jesus prays to the (...) Father to the additional claim that Jesus and the Father are numerically distinct. I argue that Oneness Pentecostals can appropriate central concepts from The Logic of God Incarnate as Morris suggests, and further that this means Oneness Pentecostals should abandon the claim that Jesus believes he just is the Father. Once Oneness Pentecostals abandon this claim, they can give a possible explanation of how it is that Jesus relates to the Father in prayer even though he just is the Father. (shrink)

G.E. Moore alludes to a notion of consciousness that is diaphanous, elusive to attention, yet detectable. Such a notion, I suggest, approximates what Bina Gupta has called `witness-consciousness'--in particular, the aspect of mode-neutral awareness with intrinsic phenomenal character. This paper offers a detailed definition and defence of the appearance and reality of witness-consciousness. While I claim that witness- consciousness captures the essence of subjectivity, and so must be accounted for in the `hard problem' of consciousness, it is not to be (...) confused with the more commonly defended notion of `for-me-ness'.

It is common to hold that our conscious experiences at a single moment are often unified. But when consciousness is unified, what are the fundamental facts in virtue of which it is unified? On some accounts of the unity of consciousness, the most fundamental fact that grounds unity is a form of singularity or oneness. These accounts are similar to Newtonian views of space according to which the most fundamental fact that grounds relations of co-spatiality between various points (or regions) (...) of a space is the fact that these points (or regions) are parts of the same single space. In this paper, I sketch and defend an alternative account of unity of consciousness. Very roughly, the view holds that experiences are unified when they are connected in the right way. In this respect, the view is analogous to Leibnizian views of space according to which the oneness of space emerges from certain conditions over spatial relations. The Leibnizian alternative has significant implications for our understanding of the metaphysics of conscious experience, the cognitive architecture of the mind and our assessment of the conditions under which unity of consciousness breaks.

Arguably no concept is more fundamental to science than that of causality, for investigations into cases of existence, persistence, and change in the natural world are largely investigations into the causes of these phenomena. Yet the metaphysics and epistemology of causality remain unclear. For example, the ontological categories of the causal relata have been taken to be objects (Hume 1739), events (Davidson 1967), properties (Armstrong 1978), processes (Salmon 1984), variables (Hitchcock 1993), and facts (Mellor 1995). (For convenience, causes and effects (...) will usually be understood as events in what follows.) Complicating matters, causal relations may be singular (Socrates’s drinking hemlock caused Socrates’s death) or general (Drinking hemlock causes death); hence the relata might be tokens (e.g., instances of properties) or types (e.g., types of events) of the category in question. Other questions up for grabs are: Are singular causes metaphysically and/or epistemologically prior to general causes or vice versa (or neither)? What grounds the intuitive asymmetry of the causal relation? Are macro-causal relations reducible to micro-causal relations? And perhaps most importantly: Are causal facts (e.g., the holding of causal relations) reducible to non-causal facts (e.g., the holding of certain spatiotemporal relations)? (shrink)

Is attention both necessary and sufficient for consciousness? Call this central question of this treatise, “Q.” We commonly have the experience of consciously paying attention to something, but is it possible to be conscious of something you are not attending to, or to attend to something of which you are not conscious? Where might we find examples of these? This treatise is a quest to find an answer to Q in two parts. Part I reviews the foundations upon which the (...) discourse on Q is built. Different inputs to Q produce different answers. After consideration of the many ways “attention” and “consciousness” have been defined, I settle upon phenomenal consciousness and Executive Attention (defined as a suite of strategies for structuring cognition for further processing implemented by the executive of working memory) as the most interesting inputs to Q, and the ones on which Part II focuses. Attention without consciousness seems relatively easy to establish empirically, but consciousness without attention is much harder. The putative candidates all seem to have major problems, but I build a strong abductive case for the hitherto ignored case of foveal phenomenal overflow. We consciously see far more detail in our foveal fields than we can Executively Attend, although there is a serious obstacle to our ever confirming that empirically—identifying conscious content relies on Executive Attentional report. Triangulating the capacity limitations of attention, consciousness, and working memory strengthens this case for consciousness without attention, and suggests that cognition must work something like my “Witches’ Hat Model,” on which content can become conscious outside of Executive Attention or working memory. I conclude with some reflections on the implications of my arguments for the discourse on Q, and for other discourses such as the ontologies of attention and consciousness, theories of consciousness, some other cognitive concepts, and ethical considerations in humans, animals, and machines. A conclusive answer to Q continues to elude us. It may perhaps be an ultimately insoluble conundrum. But it is the very essence of humanity to seek an answer, and in so doing, to improve our understanding of our own nature: “The proper study of mankind is man.”1. (shrink)

This paper defends and develops the structuring account of conscious attention: attention is the conscious mental process of structuring one’s stream of consciousness so that some parts of it are more central than others. In the first part of the paper, I motivate the structuring account. Drawing on a variety of resources I argue that the phenomenology of attention cannot be fully captured in terms of how the world appears to the subject, as well as against an atomistic conception of (...) attention. In the second part of the paper, I show how the structuring account can be made precise: attention causes and causally sustains phenomenal relations to hold between the parts of the stream of consciousness; most importantly the relation of one part being peripheral to another. I end by pointing out consequences for both the scientific study of attention as well as for several areas of central philosophical interest. (shrink)

We sometimes experience pleasures and displeasures simultaneously: whenever we eat sfogliatelle while having a headache, whenever we feel pain fading away, whenever we feel guilty pleasure while enjoying listening to Barbara Streisand, whenever we are savouring a particularly hot curry, whenever we enjoy physical endurance in sport, whenever we are touched upon receiving a hideous gift, whenever we are proud of withstanding acute pain, etc. These are examples of what we call " mixed feelings ". Mixed feelings are cases in (...) which one and the same person experiences pleasure and displeasure at the same time. Mixed feelings raise two questions: (1) If pleasure and displeasure are contraries, how can mixed feelings be possible? (2) Does the excess of pleasure (or displeasure) that we feel when experiencing mixed feelings itself constitute a new feeling, that results from the co-occurrence of the first two? I will argue (1) that mixed feelings are possible and that their existence does not threaten the contrariety of pleasure and displeasure, and (2) that there are no resultant feelings: having a lot of pleasure and a little displeasure does not result in having additional mild pleasure. Finally, I will suggest (3) that although both false, scepticism towards the existence of mixed feelings, as well as the idea according to which resultant feelings exist, are inspired from a single and correct idea: that pleasure and displeasure do fuse in some cases.

My central claim is that philosophers of mind have failed to take adequate account of empirical evidence regarding human consciousness and vision. Experiments on split-brain patients over the past fifty years reveal consciousness in both cerebral hemispheres. I claim specifically that (a) consciousness in the right hemisphere is inherited from our animal ancestors; (b) consciousness in the left hemisphere arose during human evolution in association with language; and (c) the existence of both forms of consciousness provides the best explanation for (...) many aspects of normal human experience. Evidence for two cortical visual pathways in the human brain has been expanding for twenty years. The ventral pathway is specialised for object identification, and the dorsal pathway for the control of actions in respect of those objects. The evidence has been challenged by those who have failed (a) to distinguish between the visual pathways themselves and processes served by the pathways, and (b) to recognise the specific circumstances in which actions draw on one pathway. I claim that in the left hemisphere only the ventral pathway reaches consciousness. The combination of two visual pathways with two centres of consciousness challenges traditional views about perception. I claim that (a) perception is distinct from seeing; (b) perception is limited to the left hemisphere; and (c) the parallel process in the right hemisphere is associated with the emotions. The presence of two centres of consciousness challenges traditional views on the unity of consciousness and on personhood; but it also offers an explanation for conflicting views on the emotions and the existence of self-deception. I distinguish my claims about human consciousness from the Dual Systems (or Two Minds) Theory. Although there are superficial parallels, the latter theory denies that both systems/minds are conscious, and takes no account of the specialisation of the cerebral hemispheres revealed by experiments on split-brain patients. I conclude that philosophy must incorporate empirical evidence if it is to avoid claims of irrelevance. (shrink)

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)

In this dissertation, I examine the nature and structure of consciousness. Conscious experience is often said to be phenomenally unified, and subjects of consciousness are often self-conscious. I ask whether these features necessarily accompany conscious experience. Is it necessarily the case, for instance, that all of a conscious subject's experiences at a time are phenomenally unified? And is it necessarily the case that subjects of consciousness are self-conscious whenever they are conscious? I argue that the answer to the former is (...) affirmative and the latter negative. In the first chapter, I set the stage by distinguishing phenomenal unity from other species of conscious unity. A pair of conscious states is phenomenally unified if they are experienced together as part of a single experience that encompasses them both. In this and the next two chapters I defend the thesis that, necessarily, for any subject (of conscious mental states) at any time, all of that subject's conscious mental states (at that time) are part of a single, maximal state of consciousness. I call this thesis the "Unity Thesis." I proceed by considering some preliminary questions that might be raised about the Unity Thesis. For instance, the thesis presupposes that it is coherent to talk about parts of mental states. I consider objections by Tye and Searle and argue that the notion of an experiential part is unproblematic. In the remaining pages of the chapter, I present the source of the biggest challenge to the Unity Thesis: the data gathered from split-brain subjects. The Unity Thesis is formulated using the notion of a maximal state of consciousness. In the second chapter, I attempt to precisify this notion in a way that does not pre-emptively decide the debate over the Unity Thesis. In informal terms, a maximal state of consciousness is a sum of conscious states that are i) simultaneous, ii) have the same subject, and iii) all have a conjoint phenomenology. I call this the Consensus View. I then consider two unorthodox views that the Consensus View does not take off the table: the views that a "collective consciousness" and a "spread consciousness" are possible. A collective subject is one that can enjoy the experiences of an indeterminate number of "lesser" subjects of consciousness by sharing them together with those subjects. A spread subject is one that can enjoy the experiences of an indeterminate number of lesser subjects of consciousness, but it does so, not by sharing those experiences with the lesser subjects, but by absorbing the lesser subjects of experience into itself, thereby erasing the traditional boundaries between the entities we intuitively think of as subjects of experience. I argue that, although the Consensus View does not decide against them, these views stretch the bounds of coherence and should not, therefore, be accepted. Having presented an account of what maximal state of consciousness is, I define a stream of consciousness in terms of a maximal states of consciousness. In the rest of chapter two, I consider and argue against a number of different ways of interpreting the split-brain data that are either inconsistent with the Unity Thesis or attribute more than one subject of consciousness to split-brain subjects. Among the views I consider are Lockwood's partial-unity view and the views, by theorists such as Sperry, Koch, Puccetti, Marks, and Tye, that split-brain subjects have two non-overlapping streams of consciousness. In chapter three, I consider a recent attempt by Bayne to account for the split-brain data in a way that does not attribute two streams of consciousness to them. According to Bayne's Switch Model, the consciousness of split-brain subjects can be likened to that of a ball that is passed back and forth between the two hemispheres of the upper-brain. The hemispheres take turns supporting a single stream of consciousness. I consider the empirical data in some detail and argue that the data is not as compatible with the Switch Model as Bayne claims. I close the chapter by presenting the rough outline of an interpretation of the split-brain data that is consistent with both the Unity Thesis and the split-brain data. In chapter four, I turn from defending the Unity Thesis to examining an attempt to account for conscious unity. Rosenthal has offered a theory of conscious unity as an extension of his higher-order theory of consciousness. I consider his account of conscious unity in light of a well-known objection to his theory: the (Representational) Mismatch Objection. It can be asked what it is like for a subject of experience when a higher-order state misrepresents its target first-order state. If what it is like for the subject corresponds to the content of the higher-order state, then it appears as though higher-order representation is unnecessary for conscious experience, for it would appear as though it is possible for a state to be conscious without being represented by a higher-order state. If what it is like corresponds to the content of the lower-order state, then it would again seem as though representation at the higher-order level is unnecessary for conscious experience, for the higher-order state would not seem to be doing any work in generating the experience. I consider and argue against two recent defences of Rosenthal's higher-order theory from the Mismatch Objection. Then I turn to Rosenthal's account of conscious unity. Rosenthal's account posits two mental mechanisms. I refer to the ways of accounting for conscious unity via these two mechanisms as the "gathering strategy" and the "common-ascription strategy" respectively. Both of these strategies, I argue, appear to locate the basis for certain phenomenal facts in higher-order representational facts. This raises a prima facie question: does Rosenthal's account of conscious unity land him square within the sights of the Mismatch Objection? Although the gathering strategy may ultimately be understood in a way that does not make it subject to the Mismatch Objection, Rosenthal has certain commitments that bar this strategy from serving as a complete account of conscious unity. This is problematic for Rosenthal, I argue, because his common-ascription strategy faces some difficult questions. This strategy makes conscious unity due to an implicit expectation a subject of consciousness has that, whenever he or she engages in introspection, an explicit sense of conscious unity will be generated. I argue that it is very difficult to see how such an implicit sense could both avoid the Mismatch Objection and do the work it needs to do in order to account for conscious unity. In chapter five, the discussion turns from the unity of consciousness to self-consciousness. The question that is considered in this and the last chapter is the question whether conscious experience is necessarily accompanied by self-consciousness. The affirmative answer to this question I call the Ubiquity Thesis. I spend some time distinguishing robust conceptions of self-consciousness from minimal conceptions of self-consciousness. The notion of self-consciousness invoked by the Ubiquity Thesis is a minimal one. In spite of the fact that the Ubiquity Thesis invokes only a minimal or thin conception of self-consciousness, I believe the thesis to be false and argue against it. In this chapter I take up the views of Husserl. Husserl is often regarded as the progenitor of the phenomenological tradition, a tradition in which many philosophers affirm the Ubiquity Thesis. I examine and argue against an interpretation of Husserl's work, one defended by Zahavi, according to which Husserl could be seen to defend the Ubiquity Thesis. One claim that Husserl makes is that, in order for an object to become the intentional target of a conscious state, it must be given to consciousness beforehand. It is possible, during acts of deliberate introspection, for consciousness to take itself as its object. On Husserl's view, this requires consciousness to be given to itself beforehand. This self-givenness of consciousness, argues Zahavi, can be seen as a kind of minimal self-consciousness. Husserl has also offered an account of this self-givenness of consciousness and it appears in his discussion of inner time-consciousness. I attempt to argue, using some of Husserl's other views regarding psychological stances (or standpoints), that consciousness is not given to itself outside of the adoption of a certain psychological standpoint. I also offer an alternative way of accounting for inner time-consciousness, one that does not have, as a built-in feature, that consciousness always has itself as a secondary object. In the sixth and final chapter, I take up a contemporary defence of the Ubiquity Thesis. Kriegel, a higher-order theorist like Rosenthal, has argued that every conscious state is conscious in virtue of the fact that it represents itself. This self-representation is understood as a kind of self-consciousness and, thus, his theory can be seen as affirming the Ubiquity Thesis. In the first part of the chapter, I take issue with the way in which Kriegel lays out the conceptual terrain. In particular, Kriegel countenances a property he calls "intransitive state self-consciousness." I argue that this way of speaking is confused. I then turn to considering Kriegel's account. Kriegel identifies the species of self-consciousness that pervades all of conscious experience with a peripheral awareness of one's own mental states. I argue that such a peripheral inner awareness does not accompany all of our mental states and, thus, that Kriegel's views do not give us reason to accept the Ubiquity Thesis. (shrink)

This paper explores early Australasian philosophy in some detail. Two approaches have dominated Western philosophy in Australia: idealism and materialism. Idealism was prevalent between the 1880s and the 1930s, but dissipated thereafter. Idealism in Australia often reflected Kantian themes, but it also reflected the revival of interest in Hegel through the work of ‘absolute idealists’ such as T. H. Green, F. H. Bradley, and Henry Jones. A number of the early New Zealand philosophers were also educated in the idealist tradition (...) and were influential in their communities, but produced relatively little. In Australia, materialism gained prominence through the work of John Anderson, who arrived in Australia in 1927, and continues to be influential. John Anderson had been a student of Henry Jones, who might therefore be said to have influenced both main strands of Australian philosophical thought. (shrink)

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)

This thesis has, as its primary target, the neo-cartesianism, or property dualism of certain philosophers of mind: David Chalmers, Tim Bayne, and others. All begin with a pre-theoretic commitment to the view that all perceptual states are conscious. They define consciousness by saying that it is synonymous with having ‘qualia’ – a term directed at phenomenal properties which defy reduction to physical states. The thesis argues that this position is challenged by certain neurological conditions, - blindsight, visual form agnosia etc- (...) which we can generalise as ‘dissociations’: conditions in which functions are separated from awareness. The thesis holds that these are examples of unconscious perception, which present the case for a different pre-theoretic position, and a redefinition of concepts used in the vicinity. Insofar as the neo-cartesians recognise the empirical, their inclination to reject the dissociations is challenged with new cases and paradigms which have emerged in recent years. It is contended that the dissociations disrupt Chalmers’ coherence between the phenomenal and the psychological, Bayne’s commitment to the Unity of Consciousness, and Phillips’ campaign against unconscious perception. In addition, synaesthesia is advanced as a problem case for Bayne’s unity contention. I argue that the dissociations are not easily dismissed, and present a real challenge for neo-cartesianism. In exploring this challenge, the thesis contributes to the case for a different philosophy of mind – a Higher Order Thought approach. The notion of unconscious perception – it is contended - much more easily finds an accommodation in HOT theories, so this thesis contributes to existing arguments for that position. HOT theories also have an advantage in being receptive to reduction, in giving a developmental account of consciousness, and in being more open to the accommodation of empirical discoveries. In each respect, there is an advantage over the respective positions taken by Chalmers and Bayne. (shrink)

Language is expressed in a consecutive way that is called linearity; it is acceptable to think that language understanding also occurs in a linear way. In this paper, it will be argued that although sentences are expressed in a linear way, they are not understood in the same way, because we develop an understanding of the entwined phrases forming a sentence beyond the single words. Therefore, it is argued that linearity cannot adequately explain sentence understanding. In addition, by introducing the (...) concept of mental work that is based on “the law of less work” or our natural tendency toward less mental effort, we will try to explain sentence understanding based on the ladder model instead of the linear model.

Each well-known proposed solution to the mind-body problem encounters an impasse. These take the form of an explanatory gap, such as the one between mental and physical, or between micro-subjects and macro-subject. The dialectical pressure to bridge these gaps is generating positions in which consciousness is becoming increasingly foundational. The most recent of these, cosmopsychism, typically casts the entire cosmos as a perspectival subject whose mind grounds those of more limited subjects like ourselves. I review the dialectic from materialism and (...) dualism through to panpsychism, suggesting that explanatory gaps in the latter stem from assuming foundational consciousness to be perspectival. Its renunciation may yield the notion of an aperspectival, universal, “non-dual” consciousness that grounds all manifestation and is unstructured by subject, object or any differentia. Not only is such consciousness suggestive of a natural successor to cosmopsychism, but it has also been reported to be the direct experience of mystics who claim to have transcended the individual perspective. Their purported insight — that our aperspectival conscious nature is identical to the ground of all being — has been termed “the Perennial Philosophy”. Believing this Perennial Philosophy to offer the most promising way forward in the mind-body problem, I construct from it the foundations of a metaphysical system that I call “Perennial Idealism”. This attempts to account for manifestation in terms of dispositional, imagery-bound subjects. I then address an age-old “Parmenidean” conundrum that I refer to as “the problem of the one and the many”: How can an undifferentiated substratum ground differentia without the ground itself differentiating? The proposed solution takes its cue from mystico-philosophical writings in the Advaita Vedānta tradition, known as the ajāta doctrine. (shrink)

In my dissertation I critically survey existing theories of time consciousness, and draw on recent work in neuroscience and philosophy to develop an original theory. My view depends on a novel account of temporal perception based on the notion of temporal qualities, which are mental properties that are instantiated whenever we detect change in the environment. When we become aware of these temporal qualities in an appropriate way, our conscious experience will feature the distinct temporal phenomenology that is associated with (...) the passing of time. The temporal qualities model of perception makes two predictions about the mechanisms of time perception; one that time perception is modality specific and the other that it can occur without awareness. My argument for this view partially depends on a number of psychophysical experiments that I designed and implemented myself and which investigate subjective time distortions caused by looming visual stimuli. These results show that the mechanisms of conscious experience of time are distinct from the mechanisms of time perception, as my theory of temporal qualities predicts. (shrink)

In this thesis I present a phenomenological investigation of our experience of time – of things as they fall within time – and suggest that something important goes missing in recent debates. This is the notion of a point of view. I believe that articulating the sense in which we have a point of view in time, and what this is a point of view upon, is crucial to an account of how things are for an experiencing subject. In the (...) first chapter, I elucidate the specious present. I argue that theorists appeal to the specious present under two guises without explicitly distinguishing between them; yet these two conceptions are not identical, while one entails the other the reverse is not true. In the second chapter I defend an appeal to the specious present against proponents of what I refer to as snapshot models of temporal experience. I argue that perceptual experience minimally presents something of some non-zero temporal extent as such. In the third chapter I discuss how we are to characterise experience over intervals of time of a greater extent than the specious present. I offer a proposal on which a subject is invariably presented with a positive temporal extent, with this interval marking the partition between the past and the future for the subject. In the fourth chapter I compare and contrast our experience of objects and events, and our experiential point of view in space and in time. Among other things, I argue that getting right how things are for the subject requires an appeal to the subject’s asymmetrical awareness of times either side of the specious present. In fifth and final chapter I demonstrate that appeal to an experiencing subject’s tensed temporal perspective can explain the sense in which time seems to pass. (shrink)

In the case of ventriloquism, seeing the movement of the ventriloquist dummy’s mouth changes your experience of the auditory location of the vocals. Some have argued that cases like ventriloquism provide evidence for the view that at least some of the content of perception is fundamentally multimodal. In the ventriloquism case, this would mean your experience has constitutively audio-visual content (not just a conjunction of an audio content and visual content). In this paper, I argue that cases like ventriloquism do (...) not in fact warrant that conclusion. I then try to make sense of crossmodal cases without appealing to fundamentally multimodal content.

A rigorous approach to the study of the mind–body problem is suggested. Since humans are able to talk about consciousness (produce phenomenal judgments), it is argued that the study of neural mechanisms of phenomenal judgments can solve the hard problem of consciousness. Particular methods are suggested for: (1) verification and falsification of materialism; (2) verification and falsification of interactionism; (3) falsification of epiphenomenalism and parallelism (verification is problematic); (4) verification of particular materialistic theories of consciousness; (5) a non-Turing test for (...) machine consciousness. A complex research program is constructed that includes studies of intelligent machines, numerical models of human and artificial creatures, language, neural correlates of con- sciousness, and quantum mechanisms in brain.
