Consciousness and Content

According to Sparse views of perceptual content, the phenomenal character of perceptual experience is exhausted by the experiential presentation of ‘low-level’ properties such as (in the case of vision) shapes and colours and textures Whereas, according to Rich views of perceptual content, the phenomenal character of perceptual experience can also sometimes involve the experiencing of ‘high-level’ properties such as natural kinds, artefactual kinds, causal relations, linguistic meanings, moral properties. An important dialectical tool, which has frequently been employed in the debate (...) between Rich vs. Sparse theorists, is the so-called ‘method of phenomenal contrast’. I explore how this method of phenomenal contrast interacts with the sort of content-externalism made familiar by Putnam. I show that the possibility of Twin Earth style cases places important restrictions on the range of properties that the method of phenomenal contrast could plausibly apply to. Moreover, these restrictions would apply to some paradigmatically low- level properties as well as to some of the frequently advanced high-level properties. I also draw some general lessons about the different ways one might conceive of the relation between phenomenal character and representational content. (shrink)

Skilled sportsmen or musicians—more generally, skilled agents—often fill us with awe with the way they perform their actions. One question we may ask ourselves is whether they intended to perform some awe-inspiring aspects of their actions. This question becomes all the more pressing as it often turns out that these agents were not conscious of some of those aspects at the time of performance. As I shall argue, there are reasons for suspecting lack of conscious access to an aspect of (...) one’s action to be incompatible with intending to perform that aspect of one’s action. Subsequently, though, I will also argue that, in some cases, the incompatibility is only prima facie, and can be dispelled by drawing the following distinction: that between aspects of one’s action that are merely temporarily not consciously accessed, versus aspects of one’s action that are permanently inaccessible to consciousness. I will thus remove an obstacle towards saying that skilled agents intended to perform certain aspects of their actions, despite lack of conscious access to those aspects at the time of performance.

Starting from Proust’s distinction between the self-attributive and self-evaluative views on metacognition, this paper presents a third view: self-mindshaping. Based on the notion of mindshaping as the core of social cognition, the self-mindshaping view contends that mindshaping abilities can be turned on one’s own mind. Against the self-attributive view, metacognition is not a matter of accessing representations to metarepresent them but of giving shape to those representations themselves. Against the self-evaluative view, metacognition is not blind to content but relies heavily (...) on it. We characterize our view in terms of four issues that, according to Proust, distinguish the previous approaches, namely, whether metacognitive mechanisms are the same as those employed to access other minds, whether metacognitive control requires conceptual representation, whether metacognition is propositional, and whether metacognitive access is linked to mental action. After describing some of the mechanisms for self-mindshaping, we show how this view regards metacognition as grounded on social interaction mechanisms, conceptually driven, possibly, but not necessarily, propositional, and engaged in the practical regulation of mental states. Finally, we examine the prospects for the primacy of self-mindshaping as the primary metacognitive function. We argue that self-attributive processes typically subserve the practical goals emphasized by the mindshaping view, and that the evaluative role played by procedural metacognition can be grounded on social cues rather than on experiential feelings. Even if this is not enough to claim the primacy of self-mindshaping, it still appears as a third kind of metacognition, not reducible to the other two. (shrink)

Higher-order theories of consciousness come in many varieties, but all adopt the 'transitivity principle' as a central, explanatory premise. The transitivity principle states that a mental state of a subject is conscious if and only if the subject is aware of it. This higher-order awareness is realized in different ways in different forms of higher-order theory. I argue that empirical studies of metacognition have falsified the transitivity principle by showing that there can be awareness of a mental state without that (...) state's becoming conscious. I present two such studies in detail and argue that the measures they employ cannot be interpreted in a way that would make the results compatible with higher-order theory. Since all versions of the theory rely on the transitivity principle, this entails that all forms of higher-order theory are false. (shrink)

Orthodox neurocognitive accounts of the bodily sense of agency suggest that the experience of agency arises when action-effects are anticipated accurately. In this paper, I argue that while successful anticipation is crucial for the sense of agency, the role of unsuccessful prediction has been neglected, and that inefficacy and uncertainty are no less central to the sense of agency. I will argue that this is reflected in the phenomenology of agency, which can be characterized both as the experience of efficacy (...) and effort. Specifically, the “sense of efficacy” refers to the perceptual experience of an action unfolding as anticipated. The “sense of effort”, in contrast, arises when an action has an uncertain trajectory, feels difficult, and demands the exertion of control. In this case, actions do not unfold as anticipated and require continuing adaptation if they are to be efficacious. I propose that, taken individually, the experience of efficacy and effort are insufficient for the sense of agency and that these experiences can even disrupt the sense of agency when they occur in isolation from each other. I further argue that a fully-fledged sense of agency depends on the temporally extensive process of prediction error-cancelation. This way, a comparator account can accommodate both the role of accurate prediction and prediction error and thus efficacy and effort. (shrink)

An explanatory gap exists between physics and experience, raising the hard problem of consciousness: why are certain physical systems associated with an experience of an external world from an internal perspective? The living mirror theory holds that consciousness can be understood as arising from the computational interaction between a living system and its environment that is required for the organism's existence and survival. Maintaining a boundary that protects the system against destructive forces requires an interaction between the organism and its (...) outside world that can be cast in terms of Bayesian inference. The living mirror theory holds that this computational interaction results in statistical properties of the material world that are, in the absence of life, only implicit, becoming explicit in informational terms. This is held to give rise to the beliefs in qualities that constitute consciousness. Consciousness is therefore a necessary feature of all living systems as, in a world governed by the second law of thermodynamics, survival depends on the construction of beliefs regarding the potentially destructive forces in the outside world. From this perspective, consciousness is shown to be not a property of the brain in particular but instead to be a necessary feature of the life process itself. (shrink)

An abundant literature on autism shows differences in emotional consciousness between neurotypical and autistic people. This paper proposes an interpretation of these results through a conceptual clarification of emotional consciousness. It suggests that autistic people generally access their emotions through a thirdperson's perspective whereas neurotypical people's emotions reach consciousness via first-person access. This interpretation is based on a model of 'emotional consciousness' that applies leading theories of consciousness to emotions as well as on research on the way autistic people relate (...) to their own emotions. This model differentiates two routes through which emotions can access consciousness. Therefore, research on emotions in autism helps to give a more complete account for emotional consciousness in general. (shrink)

La recente pubblicazione in lingua italiana del Libro Rosso, che è stato definito l’inedito forse più importante nella storia della psicologia, è stata celebrata in numerosi convegni specialistici, compreso quello da cui originano i saggi che costituiscono questo libro. Il Libro Rosso è il libro segreto di Jung, quello sul quale egli trascrisse in parole e immagini, per oltre sedici anni, i sogni e le visioni che popolarono la sua autoanalisi. Negli ultimi anni di vita Jung lo definiva come il (...) nucleo vitale da cui erano sbocciate tutte le intuizioni che poi aveva elaborato nei suoi testi scientifici; malgrado ciò, fu sempre riluttante alla sua pubblicazione. Al massimo, permise che qualche copia circolasse tra gli amici più intimi; progettò anche di vincolarne la pubblicazione ad almeno cinquant’anni post mortem. (shrink)

Emotions and feelings affect economic systems. This is well known as e.g. stock markets tend to react to sudden political and emotional events. However, the link between emotions, consciousness, and economic systems at a deeper level than the aggregate resulting action of people at large is yet to be explored and understood. In this paper, a first building block is presented as it is shown that a variable derived from the random numbers obtained by the Global Consciousness Project is statistically (...) related to various well-known stock market index returns. The relationship is shown to be non-linear and that variations in the variable, to some extent, predate the underlying trade. The results presented are found to be robust and qualitatively unaffected by the removal of outliers. Apart from the pure economic value of these findings, the results have truly baffling implications. This is the case as they confirm some previous unorthodox research suggesting that consciousness stretches out beyond the locally confined space of our heads and that consciousness can affect hardwaregenerated random numbers at a distance. Thus, these results put doubt on the existing paradigm with regards to consciousness and highlight the need for further research. (shrink)

The meta-problem of consciousness is to explain why we think that there is a hard problem of consciousness. On Chalmers' view of the meta-problem, our judgments about the hard problem of consciousness arise non-inferentially as a result of introspection. I raise two problems for such a non-inferentialist view of the metaproblem. It does not seem to match the psychological facts about how we come to the realization of the hard problem, and it is unclear how the view can bridge the (...) gap between the content of introspection and the content involved in formulations of the hard problem. The inferentialist view of the meta-problem, on which the hard problem results from inference, explains both the psychology and content introduction. We should therefore prefer an inferentialist view of the meta-problem. (shrink)

Chalmers (2018) maintains that even if we understood every physical process in the brain we could still wonder why these processes give rise to conscious experience. The meta-problem is the challenge of explaining why we think this 'hard problem' exists. This response to the target paper endorses illusionist accounts of three 'problem intuitions' about consciousness: duality, presentation, and revelation. Subject–object duality is explained in terms of a clash between two compelling but contradictory convictions about consciousness. Phenomenal presence is understood in (...) relation to the configurational features of sensory experiences. And intuitions of revelation are explained as due to an unfounded belief in introspective ontological access. These illusionist analyses are used to bolster the case for physicalist realism rather than to support 'strong' illusionism. In addition to addressing the meta-problem they suggest a promising approach to the hard problem as wel. (shrink)

Why is there a 'hard problem' of consciousness? Why do we seem unable to grasp intuitively that physical brain processes can be identical to experiences? Here I comment on the 'meta-problem' (Chalmers, 2018), based on previous ideas (Storm, 2014; 2018). In short: humans may be 'inborn dualists' ('neuroscepticism'), because evolution gave us two (types of) brain systems (or functional modes): one (Sp) for understanding relatively simple physical phenomena, and another (Sm) specialized for mental phenomena. Because Sp cannot deal with the (...) immense complexity of the brain processes underlying consciousness, it represents them as fundamentally different from nonmental physical phenomena (dualist intuition), using 'simulations' to produce 'Sm-type understanding'/predictions that seems radically different from 'Sp-type understanding'. (By analogy, different sensory modalities, handled by distinct brain systems, evoke qualitatively different experiences.) Brain systems for Sp representations of our brain processes never evolved, because they would be useless. When lacking a single 'template' matching different aspects of reality (objective vs. subjective = simulated), complementary 'models' are needed ('neuro-complementarity'), like the wave–particle duality in quantum mechanics. Thus, it seems plausible that Sp and Sm evolved because they were needed to cope with different challenges, and that 'problem intuitions' are side effects of these useful but different brain systems. (shrink)

Chalmers (2018) considers a wide range of possible responses to the meta-problem of consciousness. Among them is the ignorance hypothesis -- the view that there only appears to be a hard problem because of our inadequate conception of the physical. Although Chalmers quickly dismisses this view, I argue that it has much greater promise than he recognizes. The plausibility of the ignorance hypothesis depends on how exactly one frames the 'problem intuitions' that a solution to the meta-problem must explain. I (...) argue that problem intuitions are hybrid intuitions that encompass one's intuitive take on the phenomenal and one's intuitive take on the physical. The ignorance hypothesis undermines the second half of these hybrid intuitions. I show how the ignorance hypothesis is preferable to the alternatives and attempt to explain why there is such widespread resistance to this promising position. (shrink)

Integration information theories posit that the integration of information is necessary and/or sufficient for consciousness. In this paper, we focus on three of the most prominent information integration theories: Information Integration Theory, Global Workspace Theory, and Attended Intermediate-Level Theory. We begin by explicating each theory and key concepts they utilize. We then argue that the current evidence indicates that the integration of information is neither necessary nor sufficient for consciousness. Unlike GWT and AIR, IIT maintains that conscious experience is both (...) necessary and sufficient for consciousness. We present empirical evidence indicating that simple features are experienced in the absence of feature integration and argue that it challenges IIT’s necessity claim. In addition, we challenge IIT’s sufficiency claim by presenting evidence from hemineglect cases and amodal completion indicating that contents may be integrated and yet fail to give rise to subjective experience. Moreover, we present empirical evidence from subjects with frontal lesions who are unable to carry out simple instructions and argue that they are irreconcilable with GWT. Lastly, we argue that empirical evidence indicating that patients with visual agnosia fail to identify objects they report being conscious of present a challenge to AIR’s necessity claim. (shrink)

We have been left with a big challenge, to articulate consciousness and also to prove it in an artificial agent against a biological standard. After introducing Boltuc’s h-consciousness in the last paper, we briefly reviewed some salient neurology in order to sketch less of a standard than a series of targets for artificial consciousness, “most-consciousness” and “myth-consciousness.” With these targets on the horizon, we began reviewing the research program pursued by Jun Tani and colleagues in the isolation of the formal (...) dynamics essential to either. In this paper, we describe in detail Tani’s research program, in order to make the clearest case for artificial consciousness in these systems. In the next paper, the third in the series, we will return to Boltuc’s naturalistic non-reductionism in light of the neurorobotics models introduced (alongside some others), and evaluate them more completely.

The phenomenal overflow thesis states that the content of phenomenally conscious mental states can exceed our capacities of cognitive access. Much of the philosophical and scientific debate about the phenomenal overflow thesis has been focused on vision, attention, and verbal report. My view is that we feel things in our bodies that we don’t always process with the resources of cognitive access. Thinking about the question of phenomenal overflow from the perspective of embodied affect rather than the content of visual (...) experience is the novel contribution of this paper. I argue that we have reason to think that hydranencephalic children are phenomenally conscious but incapable of cognitive access. Further, I claim that we should interpret the reactive behavior of these subjects in terms of a kind of access to content that is distinct from cognitive access, I call this novel form of access ‘affective access.’.

Integrated information theory attempts to account for both the quantitative and the phenomenal aspects of consciousness, and in taking consciousness as fundamental and widespread it bears similarities to panpsychist Russellian monism. In this paper I compare IIT's and RM's response to the conceivability argument, and their metaphysical account of conscious experience. I start by claiming that RM neutralizes the conceivability argument, but that by virtue of its commitment to categoricalism it doesn't exclude fickle qualia scenarios. I argue that IIT's core (...) notion of intrinsic cause-effect power makes it incompatible with categoricalist versions of RM and, to the contrary, is best understood as entailing pandispositionalism, the view for which all properties are powers. I show that, thus construed, IIT can cope with both the conceivability and with the fickle qualia arguments, offers a promising way to account for the content of experience, and hence is preferable to categoricalist RM.

Consciousness-altering behaviour is, to a first approximation, a universal phenomenon; practically all human societies have experimented with altered states of consciousness in some form. In this article, we review the neuroscientific and psychological evidence in favour of the transient hypofrontality theory, a general brain mechanism that can account for a great number of phenomenological features shared by all ASCs. The theory is based on the conceptualization of brain areas and mental abilities into a functional hierarchy with the top layers in (...) the prefrontal cortex contributing the most sophisticated elements of the conscious experience. Analogous to peeling an onion, the THT simply postulates that alteration to consciousness involves the progressive downregulation of brain networks supporting the highest cognitive capacities, down the functional hierarchy, one phenomenological subtraction at a time, to those supporting more basic ones. Accordingly, ASCs are principally due to a transient state of hypoactivity, of various depths and extent, in networks of the prefrontal cortex. Given the universality of ASCs, we ask why hypofrontality might have evolved. (shrink)

This article reviews the most recent information and data regarding brain processes associated with altered states of consciousness. It takes a neurotheological approach, seeking to blend what is known about these states, particularly as they relate to religious and spiritual experiences, in terms of brain processes and subjective elements of the experiences. The overall goal is to provide a comprehensive model that incorporates multiple brain areas including cortical, limbic, and subcortical structures, as well as considers the various neurotransmitters that might (...) be involved. It is the hope that this framework provides a starting point for future investigations into the detailed neurophysiological and phenomenal aspects of altered states of consciousness. (shrink)

The nature of the self has long been a topic of discussion in philosophical and religious contexts, and has recently also garnered significant scientific attention. Although evidence exists to suggest the multifaceted nature of self-experience, the amount of research done on each of its putative components has not been uniform. Whereas selfreflective processing has been studied extensively, non-reflective aspects of self-experience have been the subject of comparatively little empirical research. This discrepancy may be linked to the methodological difficulties in experimentally (...) isolating the latter. Recent work suggests that one potential way to overcome these difficulties is through the experimentally-controlled administration of psychedelic substances that have the ability to reliably alter non-reflective aspects of self-experience. Here, we review what we know so far about the phenomenology of alterations in self-experience that occur as a result of the administration of psychedelics. We also introduce a taxonomy of such alterations in terms that can bridge contemporary cognitive neuroscience and research on psychedelics. We conclude that the scientific understanding of self-experience may be significantly advanced by expanding experimental paradigms and theoretical accounts to incorporate work with psychedelic substances.

We view the mind-body problem in terms of the two interconnected problems of phenomenal consciousness and mental causation, namely, how subjective conscious experience can arise from physical neurological processes and how conscious mental states can causally act upon the physical world. In order to address these problems, I develop here a non-physicalist framework that combines two apparently antithetical views: the materialist view of the mind as a product of the brain and the metaphysical view of consciousness rooted in an underlying (...) hidden reality. I discuss how this framework resolves the problem of mental causation while being simultaneously consistent with fundamental physical principles. I will elucidate how the framework ties in to the perspective of 'meaning' that acts as the bridge between physical neurological processes and the conscious mind. Moreover, we will see how both our awareness of the self and our representation of the external world are connected to this perspective. (shrink)

Daniel Dennett and others have suggested that qualia and introspectible phenomena do not exist. Dennett's account of consciousness, along with several related approaches, has been called illusionism by Keith Frankish. Frankish's analysis is helpful and provocative. As currently presented, however, his 'strong' version of illusionism suffers from several basic confusions, particularly regarding its relationship to eliminative materialism. This paper contrasts strong illusionism with an alternative that is easier to understand and more sharply focused -- fallibilist experiential realism, or, less technically, (...) modest realism. Fallibilist realism affirms the existence of experiential states that are commonly considered qualitative and phenomenal, but shares Frankish's agenda of thoroughly re-evaluating our judgments about such experiences. To illustrate the advantages of modest realism, I compare the ways illusionism and modest realism address two challenging puzzles: explaining how qualitative differences among sensory experiences could be constituted by differences among neural states, and explaining how neural states could constitute any conscious experiences whatsoever.

This paper addresses John Searle's criticism of the integrated information theory of consciousness. Among other things, Searle claimed that, since information is a syntactic notion, IITC cannot account for the content of consciousness. He also argued that IITC cannot explain consciousness in causal terms. In this paper, I demonstrate that the original formulation of IITC is compatible with a structuralist reading. After that, I explain how a structuralist reconstruction of IITC could deal with the objections that Searle raised. Among other (...) things, I argue that IITC could provide genuine scientific explanations of consciousness, but the explanations are to be presented in structural, rather than causal, terms.

We present the results of a phenomenological methodology that allowed for the investigation of the experience of understanding an abstract mathematical object as effectively lived by active mathematicians. Our method of analysis reveals the essential structure of such a phenomenon and, as a consequence, permits us to address the conditions of possibility for the occurrence of this particular phenomenon. We show that the different modalities of the experience of understanding an abstract mathematical object, as unearthed by the elucidation of the (...) three phenomenological classes reflect -- in addition to well-expected mathematical functional aspects -- what we call an embodiment of abstraction.

This paper tells the story of consciousness from each of the three 'person' perspectives of the English language, with the author arguing for the equally fundamental social and personal bases of human consciousness. The 'lived' second-person position of ecological psychology is the starting point for the organic, yet socially embedded, consciousness of the non-symbolic human infant. First- and third-person positions are 'reflective' sociohistorical perspectives enabled by the development of symbolic functioning. The paper presents Llinás's compelling evolutionary account but supplements this (...) third-person narrative to do justice to the profound transformation of conscious experience in the human species. Prefacing its account of consciousness from a first-person perspective, the paper argues for a developmental model that privileges both the organic and the sociohistorical bases of consciousness. Our introspections may not tease apart these influences, but they must be acknowledged as we consider what Gelernter refers to as the 'tides of our minds'. (shrink)

An astrologer (McRitchie) replied to our article criticizing the claims of astrologers who hold that psychic or supernatural factors play a role in astrological readings (JCS, 2003). However, McRitchie mistakes our 2003 JCS article 'Is Astrology Relevant to Consciousness and Psi' for an attack on astrology when it merely asks if the performance of astrologers has implications for consciousness and psi. For example, he attempts to validate astrology by citing studies we ignored and by highlighting the supposed flaws that made (...) our tests useless. A proper scientific validation of astrology or any other practical field would critically review the existing empirical studies and then demonstrate replication of effect sizes commensurate with the claims. But McRitchie does not do this, which is most easily explained by the seeming impossibility of doing so. Our conclusion that the performance of astrologers has no useful implications for consciousness and psi is unchanged by recent or previously missed studies, whose outcomes we describe. (shrink)

In our society, where interest in Buddhist meditation is expanding enormously, numerous scientific studies are now conducted on the neurophysiological effects of meditation practices and on the neural correlates of meditative states. However, very few studies have been conducted on the experience associated with contemplative practice: what it is like to meditate -- from moment to moment, at different stages of practice -- remains almost invisible in contemporary contemplative science. Recently, 'micro-phenomenological' interview methods have been developed to help us become (...) aware of lived experience and describe it with rigour and precision. The present article presents the results of a pilot project1 aimed at applying these methods to the description of meditative experience. The first part of the article describes these methods and their adjustment for the investigation of meditative experience. The second part provides micro- phenomenological descriptions of two processes of which meditation practice enables the practitioner to become aware: the process of losing contact with the current situation and generation of virtual ones in 'mind-wandering' episodes, and the process of emergence of a thought. The third part of the article highlights the interest such descriptions may have for practitioners and for teachers of meditation, defines the status of these results, and outlines directions for further research.

Episodic memory provides a peculiarly intimate kind of access to our experiential past. Does this tell us anything about the nature of time, and in particular the basis of time's direction? This paper will argue that the causal theory of temporal direction enables us to unify a number of the key features of episodic memory: its being about particular past experiences, its reliable representation of experiences as past, and the derivative nature of this kind of access to the past: that (...) is, what the memory is about, and how reliable it is, depends on the content and reliability of the original experience on which the memory is based.

For over a century we have attempted to understand human aesthetic experience using scientific methods. A typical experiment could be described as reductive and quasi-psychophysical. We vary some aspect of the stimulus and systematically measure some aspect of the aesthetic response. The limitations of this approach can be categorized as problems on the Y axis and the X axis. The most enigmatic components of aesthetic experience include inclination to cry, aesthetic rapture, a sense of the sublime, and intense fascination. However, (...) we cannot evoke these 'hot' aesthetic emotions in the lab, at least not with well controlled stimuli on multiple trials. We thus resort to measuring cold, cognitive preference ratings. There are also problems on the X axis. The reductive psychophysical approach explicitly assumes that there are lawful relations between different stimulus dimensions and preferences. It also tacitly assumes that these dimensions are independent and orthogonal. The second assumption is implausible. Whatever stimulus-preference laws we discover are likely to be twisted and modulated when another dimension is added to the stimuli. This 'gestalt nightmare' has long been recognized, but never resolved. This matters, because human aesthetic faculties are probably tuned to the balance and relationship of parts which make up a whole and are indifferent to the parts presented in isolation. I conclude that the future of scientific aesthetics depends on how successfully we can transcend reductive, quasi-psychophysical approaches. (shrink)

Phenomenal consciousness can be conceptualized innocently enough that its existence should be accepted even by philosophers who wish to avoid dubious epistemic and metaphysical commitments such as dualism, infallibilism, privacy, inexplicability, or intrinsic simplicity. Definition by example allows us this innocence. Positive examples include sensory experiences, imagery experiences, vivid emotions, and dreams. Negative examples include growth hormone release, dispositional knowledge, standing intentions, and sensory reactivity to masked visual displays. Phenomenal consciousness is the most folk-psychologically obvious thing or feature that the (...) positive examples possess and that the negative examples lack, and which preserves our ability to wonder, at least temporarily, about antecedently unclear issues such as consciousness without attention and consciousness in simpler animals. As long as this concept is not empty, or broken, or a hodgepodge, we can be phenomenal realists without committing to dubious philosophical positions. (shrink)

There is no phenomenal consciousness; there is nothing 'that it is like' to be me. To believe in phenomenal consciousness or 'what-it's-like-ness' or 'for-me-ness' is to succumb to a pernicious form of the Myth of the Given. I argue that there are no good arguments for the existence of such a kind of consciousness and draw on arguments from Buddhist philosophy of mind to show that the sense that there is such a kind of consciousness is an instance of cognitive (...) illusion.

By reviewing most of the neurobiology of consciousness, this article highlights some major reasons why a successful emulation of the dynamics of human consciousness by artificial intelligence is unlikely. The analysis provided leads to conclude that human consciousness is epigenetically determined and experience and context-dependent at the individual level. It is subject to changes in time that are essentially unpredictable. If cracking the code to human consciousness were possible, the result would most likely have to consist of a temporal pattern (...) code simulating long-distance signal reverberation and de-correlation of all spatial signal contents from temporal signals. In the light of the massive evidence for complex interactions between implicit (non-conscious) and explicit (conscious) contents of representation, the code would have to be capable of making implicit (non-conscious) processes explicit. It would have to be capable of a progressively less and less arbitrary selection of temporal activity patterns in a continuously developing neural network structure identical to that of the human brain, from the synaptic level to that of higher cognitive functions. The code’s activation thresholds would depend on specific temporal signal coincidence probabilities, vary considerably with time and across individual experience data, and would therefore require dynamically adaptive computations capable of emulating the properties of individual human experience. No known machine or neural network learning approach has such potential. (shrink)

I try to reconcile Dretske's representational theory of conscious mental states with Rosenthal's higher-order thought theory of conscious mental states by arguing that Rosenthal's HOT can make room for the notion of a state of consciousness whereby an invidual may be conscious of an object or property without thereby being conscious of being in such a state.

I examine and criticize John Searle's view of the relationships between consciousness, intentionality and function.

I make a few comments concerning the way Recanati analyses imaginary situations in two realms : : the realm of the fictional and the realm of the ascription of beliefs.

In God and Phenomenal Consciousness, Yujin Nagasawa bridges debates in two distinct areas of philosophy: the philosophy of mind and the philosophy of religion. First, he introduces some of the most powerful arguments against the existence of God and provides objections to them. He then presents a parallel structure between these arguments and influential arguments offered by Thomas Nagel and Frank Jackson against the physicalist approach to phenomenal consciousness. By appealing to this structure, Nagasawa constructs novel objections to Jackson's and (...) Nagel's arguments. Finally, he derives, from the failure of these arguments, a unique metaphysical thesis, which he calls 'non-theoretical physicalism'. Through this thesis, he shows that although this world is entirely physical, there are physical facts that cannot be captured even by complete theories of the physical sciences. (shrink)

Representationalism is widely thought to grease the skids of ontological reduction. If phenomenal character is just a certain sort of intentional content, representationalists argue, the hard problem of accommodating consciousness within a broadly naturalistic view of the world reduces to the much easier problem of accommodating intentionality. I argue, however, that there’s a fatal flaw in this reasoning, for if phenomenal character really is just a certain sort of intentional content, it’s not anything like the sort of intentional content described (...) by our best naturalistic theories. These theories make intentional content a mere Cambridge property of intentional states, a property that can be gained or lost through changes to distinct and causally disconnected objects. But consciousness is manifestly not like this; consciousness cannot suffer a mere Cambridge change. Thus, whatever ground is gained by explaining the phenomenal in terms of the intentional is lost again by undermining our best attempts to explain the intentional in terms of the natural. A Pyrrhic victory at best. (shrink)

According to the most popular theories of intentionality, a family of theories we will refer to as “functional intentionality,” a machine can have genuine intentional states so long as it has functionally characterizable mental states that are causally hooked up to the world in the right way. This paper considers a detailed description of a robot that seems to meet the conditions of functional intentionality, but which falls victim to what I call “the composition problem.” One obvious way to escape (...) the problem (arguably, the only way) is if the robot can be shown to be a moral patient – to deserve a particular moral status. If so, it isn’t clear how functional intentionality could remain plausible (something like “phenomenal intentionality” would be required). Finally, while it would have seemed that a reasonable strategy for establishing the moral status of intelligent machines would be to demonstrate that the machine possessed genuine intentionality, the composition argument suggests that the order of precedence is reversed: The machine must first be shown to possess a particular moral status before it is a candidate for having genuine intentionality.

Both Ludwig and Thomasson question my claim that many phenomenal features are intentional features. Further, Ludwig raises numerous objections to my claim that higher order mental representation is not essential to phenomenal consciousness. While Thomasson does not share those objections, she wonders how my view permits me to make first-person knowledge of mind depend on phenomenal consciousness. I respond to these challenges, drawing together questions about the forms of mental representation, the phenomenal character of sensory experience, rational agency, and introspection.
