False consciousness requires a general explanation for why, and how, oppressed individuals believe propositions against, as opposed to aligned with, their own well-being in virtue of their oppressed status. This involves four explanatory desiderata: belief acquisition, content prevalence, limitation, and systematicity. A social constructionist approach satisfies these by understanding the concept of false consciousness as regulating social research rather than as determining the exact mechanisms for all instances: the concept attunes us to a complex of mechanisms conducing oppressed individuals to (...) mistake social understandings of themselves as natural self-understandings—the limits lie where these overlap (sometimes), or are entirely absent.

In this paper, I argue that no theory of consciousness can simultaneously respect four initially plausible metaphysical claims – namely, ‘first-person realism’, ‘non-solipsism’, ‘non-fragmentation’, and ‘one world’ – but that any three of the four claims are mutually consistent. So, theories of consciousness face a ‘quadrilemma’. Since it will be hard to achieve a consensus on which of the four claims to retain and which to give up, we arrive at a landscape of competing theories, all of which have pros (...) and cons. I will briefly indicate which kinds of theories correspond to the four horns of the quadrilemma. (shrink)

This third paper locates the synthetic neurorobotics research reviewed in the second paper in terms of themes introduced in the first paper. It begins with biological non-reductionism as understood by Searle. It emphasizes the role of synthetic neurorobotics studies in accessing the dynamic structure essential to consciousness with a focus on system criticality and self, develops a distinction between simulated and formal consciousness based on this emphasis, reviews Tani and colleagues' work in light of this distinction, and ends by forecasting (...) the increasing importance of synthetic neurorobotics studies for cognitive science and philosophy of mind going forward, finally in regards to most- and myth-consciousness.

In _Matter and Consciousness_, Paul Churchland presents a concise and contemporary overview of the philosophical issues surrounding the mind and explains the main theories and philosophical positions that have been proposed to solve them. Making the case for the relevance of theoretical and experimental results in neuroscience, cognitive science, and artificial intelligence for the philosophy of mind, Churchland reviews current developments in the cognitive sciences and offers a clear and accessible account of the connections to philosophy of mind. For this (...) third edition, the text has been updated and revised throughout. The changes range from references to the iPhone's "Siri" to expanded discussions of the work of such contemporary philosophers as David Chalmers, John Searle, and Thomas Nagel. Churchland describes new research in evolution, genetics, and visual neuroscience, among other areas, arguing that the philosophical significance of these new findings lies in the support they tend to give to the reductive and eliminative versions of materialism. Matter and Consciousness, written by the most distinguished theorist and commentator in the field, offers an authoritative summary and sourcebook for issues in philosophy of mind. It is suitable for use as an introductory undergraduate text. (shrink)

Intuitively, we can conceive of the existence of a conscious state as a pure activity that does not necessarily require a body (or even a brain). This idea has found new support in certain recent theories that present the possibility of a totally disconnected and disembodied consciousness. Against this hypothesis, I argue that human experience is intrinsically embodied and embedded, though in a specific way. Using Sartre’s phenomenology of the body, I first analyze the concept of consciousness as intentionality and (...) a world-disclosing activity, thus explaining how conscious activity can only be expressed through a body that is spatiotemporally related to the world. Then, I argue that bodily consciousness does not necessarily imply the actual presence of an anatomical body but, rather, a process of spatialization and temporalization (hodological space and temporal synthesis) through the “spatiotemporal body”. Finally, I test my thesis by critiquing some cases of apparent disembodied/disconnected consciousness, i.e., dreams, out-of-body experiences, and the brain-in-a-vat scenario. (shrink)

Direct neurological and especially imaging-driven investigations into the structures essential to naturally occurring cognitive systems in their development and operation have motivated broadening interest in the potential for artificial consciousness modeled on these systems. This first paper in a series of three begins with a brief review of Boltuc’s (2009) “brain-based” thesis on the prospect of artificial consciousness, focusing on his formulation of h-consciousness. We then explore some of the implications of brain research on the structure of consciousness, finding limitations (...) in biological approaches to the study of consciousness. Looking past these limitations, we introduce research in artificial consciousness designed to test for the emergence of consciousness, a phenomenon beyond the purview of the study of existing biological systems.

In the following article, I aim to elucidate the meaning and scope of Spinoza’s vocabulary related to ‘consciousness’. I argue that Spinoza, at least in his Ethics, uses this notion consistently, although rarely. He introduces it to account for the knowledge we may have of the mind considered alone, as conceptually distinct from the body. This serves two purposes in Spinoza’s Ethics: to explain our illusion of a free will, on the one hand, and to refer to the knowledge we (...) have of our mind as something eternal, on the other. I contend, therefore, that we should not confuse Spinoza’s technical use of the notion of ‘consciousness’ with the ‘degrees of animation’ that he also evokes in the Ethics. Consciousness, for Spinoza, is neither a faculty, nor a property specific to certain minds or ideas. Furthermore, consciousness does not come in degrees. Indeed, Spinoza’s account of consciousness is not intended to differentiate kinds of minds in terms of awareness of their respective ideas. (shrink)

Ambitious higher-order theories of consciousness aim to account for conscious states when these are understood in terms of what-it-is-like-ness. This paper considers two arguments concerning this aim, and concludes that ambitious theories fail. The misrepresentation argument against HO theories aims to show that the possibility of radical misrepresentation—there being a HO state about a state the subject is not in—leads to a contradiction. In contrast, the awareness argument aims to bolster HO theories by showing that subjects are aware of all (...) their conscious states. Both arguments hinge on how we understand two related notions which are ubiquitous in discussions of consciousness: those of what-it-is-like-ness and there being something it is like for a subject to be in a mental state. This paper examines how HO theorists must understand the two crucial notions if they are to reject the misrepresentation argument but assert the awareness argument. It shows that HO theorists can and do adopt an understanding—the HO reading—which seems to give them what they want. But adopting the HO reading changes the two arguments. On this reading, the awareness argument tells us nothing about those states there is something it is like to be in, and so offers no support to ambitious HO theories. And to respond to the misrepresentation understood according to the HO reading is to simply ignore the argument presented, and so to give no response at all. As things stand, we should deny that HO theories can account for what-it-is-like-ness. (shrink)

An overview of higher-order representational theories of consciousness. Representational theories of consciousness attempt to reduce consciousness to “mental representations” rather than directly to neural or other physical states. This approach has been fairly popular over the past few decades. Examples include first-order representationalism (FOR) which attempts to explain conscious experience primarily in terms of world-directed (or first-order) intentional states (Tye 2005) as well as several versions of higher-order representationalism (HOR) which holds that what makes a mental state M conscious is (...) that it is the object of some kind of higher-order mental state directed at M. The primary focus of this entry is on HOR and especially higher-order thought (HOT) theory. The key question that should be answered by any theory of consciousness is: What makes a mental state a conscious mental state? Section 1 introduces the overall representationalist approach to consciousness and briefly discuss Tye’s FOR. Section 2 presents three major versions of HOR: higher-order thought theory, dispositional higher-order thought theory, and higher-order perception theory. In section 3, a number of common and important objections and replies are presented. Section 4 briefly outlines a close connection between HOT theory and conceptualism, that is, the claim that the representational content of a perceptual experience is entirely determined by the conceptual capacities the perceiver brings to bear in her experience. Section 5 examines several hybrid higher-order and “self-representational” theories of consciousness which all hold that conscious states are self-directed in some way. Section 6 addresses the potentially damaging claim that HOT theory requires neural activity in the prefrontal cortex (PFC) in order for one to have conscious states. (shrink)

Cognitive science typically postulates unconscious mental phenomena, computational or otherwise, to explain cognitive capacities. The mental phenomena in question are supposed to be inaccessible in principle to consciousness. I try to show that this is a mistake, because all unconscious intentionality must be accessible in principle to consciousness; we have no notion of intrinsic intentionality except in terms of its accessibility to consciousness. I call this claim the The argument for it proceeds in six steps. The essential point is that (...) intrinsic intentionality has aspectual shape: Our mental representations represent the world under specific aspects, and these aspectual features are essential to a mental state's being the state that it is.

A broad range of evidence regarding the functional organization of the vertebrate brain – spanning from comparative neurology to experimental psychology and neurophysiology to clinical data – is reviewed for its bearing on conceptions of the neural organization of consciousness. A novel principle relating target selection, action selection, and motivation to one another, as a means to optimize integration for action in real time, is introduced. With its help, the principal macrosystems of the vertebrate brain can be seen to form (...) a centralized functional design in which an upper brain stem system organized for conscious function performs a penultimate step in action control. This upper brain stem system retained a key role throughout the evolutionary process by which an expanding forebrain – culminating in the cerebral cortex of mammals – came to serve as a medium for the elaboration of conscious contents. This highly conserved upper brainstem system, which extends from the roof of the midbrain to the basal diencephalon, integrates the massively parallel and distributed information capacity of the cerebral hemispheres into the limited-capacity, sequential mode of operation required for coherent behavior. It maintains special connective relations with cortical territories implicated in attentional and conscious functions, but is not rendered nonfunctional in the absence of cortical input. This helps explain the purposive, goal-directed behavior exhibited by mammals after experimental decortication, as well as the evidence that children born without a cortex are conscious. Taken together these circumstances suggest that brainstem mechanisms are integral to the constitution of the conscious state, and that an adequate account of neural mechanisms of conscious function cannot be confined to the thalamocortical complex alone.

In recent years, there has been much focus on the apparent heterogeneity of schizophrenic symptoms. By contrast, this article proposes a unifying account emphasizing basic abnormalities of consciousness that underlie and also antecede a disparate assortment of signs and symptoms. Schizophrenia, we argue, is fundamentally a self-disorder or ipseity disturbance that is characterized by complementary distortions of the act of awareness: hyperreflexivity and diminished self-affection. Hyperreflexivity refers to forms of exaggerated self-consciousness in which aspects of oneself are experienced as akin (...) to external objects. Diminished self-affection or self-presence refers to a weakened sense of existing as a vital and self-coinciding source of awareness and action. This article integrates recent psychiatric research and European phenomenological psychiatry with some current work in cognitive science and phenomenological philosophy. After introducing the phenomenological approach along with a theoretical account of normal consciousness and self-awareness, we turn to a variety of schizophrenic syndromes. We examine positive, then negative, and finally disorganization symptoms—attempting in each case to illuminate shared distortions of consciousness and the sense of self. We conclude by discussing the possible relevance of this approach for identifying early schizophrenic symptoms. (shrink)

This chapter focuses on the relationship between consciousness and knowledge, and in particular on the role perceptual consciousness might play in justifying beliefs about the external world. We outline a version of phenomenal dogmatism according to which perceptual experiences immediately, prima facie justify certain select parts of their content, and do so in virtue of their having a distinctive phenomenology with respect to those contents. Along the way we take up various issues in connection with this core theme, including the (...) possibility of immediate justification, the dispute between representational and relational views of perception, the epistemic significance of cognitive penetration, the question of whether perceptual experiences are composed of more basic sensations and seemings, and questions about the existence and epistemic significance of high-level content. In a concluding section we briefly consider how some of the topics pursued here might generalize beyond perception. (shrink)

The paper discusses the utility of the notion of consciousness for the behavioural and brain sciences. It describes four distinctively different senses of 'conscious', and argues that to cope with the heterogeneous phenomena loosely indicated thereby, these sciences not only do not but should not discuss them in terms of 'consciousness'. It is thus suggested that 'the problem' allegedly posed to scientists by consciousness is unreal; one need neither adopt a realist stance with respect to it, nor include the term (...) and its cognates in the sciences' conceptual apparatus. The paper briefly examines Nagel's [1974] article, since this presents the strongest counter to the thesis proposed. (shrink)

Following the seminal work of Ingvar (1985. “Memory for the future”: An essay on the temporal organization of conscious awareness. Human Neurobiology, 4, 127–136), Suddendorf (1994. The discovery of the fourth dimension: Mental time travel and human evolution. Master’s thesis. University of Waikato, Hamilton, New Zealand), and Tulving (1985. Memory and consciousness. Canadian Psychology/Psychologie Canadienne, 26, 1–12), exploration of the ability to anticipate and prepare for future contingencies that cannot be known with certainty has grown into a thriving research enterprise. (...) A fundamental tenet of this line of inquiry is that future-oriented mental time travel, in most of its presentations, is underwritten by a property or an extension of episodic recollection. However, a careful conceptual analysis of exactly how episodic memory functions in this capacity has yet to be undertaken. In this paper I conduct such an analysis. Based on conceptual, phenomenological, and empirical considerations,I conclude that the autonoetic component of episodic memory, not episodic memory per se, is the causally determinative factor enabling an individual to project him or herself into a personal future.

According to Rosenthal's higher-order thought (HOT) theory of consciousness, one is in a conscious mental state if and only if one is aware of oneself as being in that state via a suitable HOT. Several critics have argued that the possibility of so-called targetless HOTs—that is, HOTs that represent one as being in a state that does not exist—undermines the theory. Recently, Wilberg (2010) has argued that HOT theory can offer a straightforward account of such cases: since consciousness is a (...) property of mental state tokens, and since there are no states to exhibit consciousness, one is not in conscious states in virtue of targetless HOTs. In this paper, I argue that Wilberg's account is problematic and that Rosenthal's version of HOT theory, according to which a suitable HOT is both necessary and sufficient for consciousness, is to be preferred to Wilberg's account. I then argue that Rosenthal's account can comfortably accommodate targetless HOTs because consciousness is best understood as a property of individuals, not a property of states. (shrink)

A reductionistic, bottom‐up, cellular‐based concept of the origins of sentience and consciousness has been put forward. Because all life is based on cells, any evolutionary theory of the emergence of sentience and consciousness must be grounded in mechanisms that take place in prokaryotes, the simplest unicellular species. It has been posited that subjective awareness is a fundamental property of cellular life. It emerges as an inherent feature of, and contemporaneously with, the very first life‐forms. All other varieties of mentation are (...) the result of evolutionary mechanisms based on this singular event. Therefore, all forms of sentience and consciousness evolve from this original instantiation in prokaryotes. It has also been identified that three cellular structures and mechanisms that likely play critical roles here are excitable membranes, oscillating cytoskeletal polymers, and structurally flexible proteins. Finally, basic biophysical principles are proposed to guide those processes that underly the emergence of supracellular sentience from cellular sentience in multicellular organisms. (shrink)

Dualist and Reductionist theories of mind disagree about whether or not consciousness can be reduced to a state of or function of the brain. They assume, however, that the contents of consciousness are separate from the external physical world as-perceived. According to the present paper this assumption has no foundation either in everyday experience or in science. Drawing on evidence for perceptual projection in both interoceptive and exteroceptive sense modalities, the case is made that the physical world as-perceived is a (...) construct of perceptual processing and, therefore, part of the contents of consciousness. A finding which requires a Reflexive rather than a Dualist or Reductionist model of how consciousness relates to the brain and the physical world. The physical world as-perceived may, in turn be thought of as a biologically useful model of the world as described by physics. Redrawing the boundaries of consciousness to include the physical world as-perceived undermines the conventional separation of the 'mental' from the physical', and with it the very foundation of the Dualist-Reductionist debate. The alternative Reflexive model departs radically from current conventions, with consequences for many aspects of consciousness theory and research. Some of the consequences which bear on the internal consistency and intuitive plausibility of the model are explored, e.g. the causal sequence in perception, representationalism, a suggested resolution of the Realism versus Idealism debate, and the way manifest differences between physical events as-perceived and other conscious events are to be construed. In the present paper I wish to challenge some of our most deeply-rooted assumptions about what consciousness is, by re-examining how consciousness, the human brain, and the surrounding physical world relate to each other.

blurb from publisher: "In Apperception and Self-Consciousness in Kant and German Idealism, Dennis Schulting examines the themes of reflexivity, self-consciousness, representation and apperception in the philosophy of Immanuel Kant and German Idealism more widely. Central to Schulting’s argument is the claim that all of human experience is inherently self-referential and that this is part of a self-reflexivity of thought, or what is called transcendental apperception, a Kantian insight that was first apparent in the work of Christian Wolff and came to (...) inform all of German Idealism. In a rigorous text suitable for students of German philosophy and upper-level students of metaphysics, epistemology, moral and political philosophy, and aesthetics courses, the author establishes the historical roots of Kant’s thought and traces it through to his immediate successors Karl Leonhard Reinhold, Johann Gottlieb Fichte and Georg Wilhelm Friedrich Hegel. He specifically examines the cognitive role of self-consciousness and its relation to idealism and places it in a clear and coherent history of rationalist philosophy." . (shrink)

Induced by intake of the psychedelic substances LSD, psilocybin, DMT and mescaline, psychedelic experiences have been extensively described by subjects as entailing a most unusual increase in the scope and quality of their consciousness. Accordingly, psychedelic experiences have been widely characterised as an “expansion of consciousness.” This article poses the following question, as yet unaddressed in contemporary philosophy and the tradition of phenomenology: to what exactly does “expansion of consciousness” refer as a general characterisation of psychedelic experiences, and what role (...) might attention play therein? On the basis of Aron Gurwitsch’s phenomenology of attention, the following thesis is presented: (a) “expansion of consciousness” refers to a particular restructuration of consciousness in psychedelic experiences. (b) This occurs by means of certain extreme transformations in direction, scope, mode and degree of attention. In order to explicate this thesis, the characteristic features of psychedelic experiences that pertain to expansion of consciousness and attention are first systematically identified from a survey of subject reports. Second, it is demonstrated that the few previous attempts to understand expansion of consciousness in terms of attention as a filter/reducing-valve, spotlight or zoom-lens each fail to explain how consciousness is structured in psychedelic experiences. Third, it is argued that psychedelic expansion of consciousness is a general restructuration of consciousness by means of extreme attentional transformations. In conclusion, brief consideration is given to the question of whether psychedelic expansion of consciousness can have epistemic and ethical value for life. (shrink)

Consciousness is seen as a difficult “binding” problem. Binding, a process where different sensations evoked by an item are associated in the nervous system, can be viewed as a process similar to associative learning. Several reports that consciousness is associated with some form of memory imply that different forms of memories have a common feature contributing to consciousness. Based on a proposed synaptic mechanism capable of explaining different forms of memory, we developed a framework for consciousness. It is based on (...) the formation of semblance of sensory stimulus from (1) synaptic semblances when excitatory postsynaptic potentials arrive at functionally LINKed postsynaptic membranes, and (2) network semblances when these potentials summate to elicit action potential initiating activity in a network of neurons. It is then possible to derive a framework for consciousness as a multi-dimensional semblance. According to this framework, a continuum of semblances formed from background sensory stimuli and oscillating neuronal activities serve to maintain consciousness. Feasibility of this framework to explain various physiological and pathological states of consciousness, its subjective nature and qualia is examined. (shrink)

Colin McGinn presents his latest work on consciousness in ten interlinked papers, four of them previously unpublished. He extends and deepens his controversial solution to the mind-body problem, defending the view that consciousness is both ontologically unproblematic and epistemologically impenetrable. He also investigates the basis of our knowledge that there is a mind-body problem, and the bearing of this on attempted solutions. McGinn goes on to discuss the status of first-person authority, the possibility of atomism with respect to consciousness, extreme (...) dualism, and the role of non-existent objects in constituting intentionality. He argues that traditional claims about our knowledge of our own mind and of the external world can be inverted; that atomism about the conscious mind might turn out to be true; that dualism is more credible the more extreme it is; and that all intentionality involves non-existent objects. These are all surprising positions, but he contends that what the philosophy of mind needs now is 'methodological radicalism' - a willingness to consider new and seemingly extravagant ideas.

Information processing in neural systems can be described and analysed at multiple spatiotemporal scales. Generally, information at lower levels is more fine-grained but can be coarse-grained at higher levels. However, only information processed at specific scales of coarse-graining appears to be available for conscious awareness. We do not have direct experience of information available at the scale of individual neurons, which is noisy and highly stochastic. Neither do we have experience of more macro-scale interactions, such as interpersonal communications. Neurophysiological evidence (...) suggests that conscious experiences co-vary with information encoded in coarse-grained neural states such as the firing pattern of a population of neurons. In this article, we introduce a new informational theory of consciousness: Information Closure Theory of Consciousness (ICT). We hypothesise that conscious processes are processes which form non-trivial informational closure (NTIC) with respect to the environment at certain coarse-grained scales. This hypothesis implies that conscious experience is confined due to informational closure from conscious processing to other coarse-grained scales. ICT proposes new quantitative definitions of both conscious content and conscious level. With the parsimonious definitions and a hypothesise, ICT provides explanations and predictions of various phenomena associated with consciousness. The implications of ICT naturally reconcile issues in many existing theories of consciousness and provides explanations for many of our intuitions about consciousness. Most importantly, ICT demonstrates that information can be the common language between consciousness and physical reality. (shrink)

Kant is said to be the first to distinguish between consciousness of oneself as the subject of one’s experiences and consciousness of oneself as an object, which he calls transcendental and empirical apperception, respectively. Of these, it is empirical apperception that is meant to enable consciousness of any empirical features of oneself; what this amounts to, however, continues to puzzle interpreters. I argue that a key to understanding what empirical apperception consists in is Kant’s claim that each type of apperception (...) corresponds to a distinct type of unity of apperception—that is, a distinct way in which representations can be related for a subject. Whereas transcendental unity of apperception requires that representations be actively combined by the understanding, empirical unity of apperception obtains when representations are passively combined by the reproductive imagination. In light of this, I develop a novel account of Kant’s two types of apperception, according to which they correspond to a cognitive subject’s consciousness of two essential aspects of herself—namely, her spontaneity and receptivity.

_The purpose_ of the article is to comprehend the Husserlian model of constituting temporal modes through the ability of intentional "retentional-protentional" consciousness, as well as to clarify the possibility of interpreting its positions in the reconstruction of the concept of anthropic time. _Theoretical basis._ The theoretical framework of the research includes: 1) the interpretation of the phenomenological reflection of "time-consciousness" by E. Husserl in the context of solving the problem of phased-differentiation of this form of temporality; 2) the concept of (...) anthropic time (V. Khanzhy). _Originality._ For the first time in research literature, the possibilities of applying the ideas of Husserl to the reconstruction of the concept of anthropic time are considered through the interpretation of the phenomenological solution to the problem of temporality, proposed and specified in Husserl’s "time-consciousness" concept. _Conclusions._ The comprehension of the Husserlian model of intentionality of consciousness through the "grasping-from-now" and the constitution of phases of phenomenological time through the component of "exiting-from-now" showed that solving the problem of phased-differentiation of phenomenological time leads to the observation of the impossibility of isolating the modes of past, present, and future as self-sufficient and unconditional. More accurate indications, based on the constitutive intentionality of consciousness on the "grasping-from-now" phases of time (as conventional), are as follows: a) the abilities of retention and recollection are the foundation for the constitution of the past and its connections to the present; b) the perception establishes the basis for the phase of the present itself; c) the possibilities of protention and anticipation (as forms of imagination) constitute the future and its connections to the present. By the concept of retention, Husserl fixes a certain primary memory (the present "now" of a past interval), which enables retaining the past in the present. The category of recollection or secondary memory is used by the philosopher to refer to the self-sufficient reproduction of past experiences (without being joined to present perception). The fundamental difference between recollection and retention is that the former _re-_presents a temporal interval, grasping its content and reproducing it as it was in the past, while in the latter, the perceived duration is presented as a fragment of time that has just passed. According to the German philosopher, the "grasping" of the present phase is performed by perception. Through the constitutive intentionality of consciousness, perception synthesizes the results of primary-actual activity and retentional holding of duration. The second part of the article will present solutions to the following research tasks: 1) analysis of the possibilities of protention and anticipation in constituting the future and its connections with the present; 2) understanding the possibility of using interpreted forms of Husser’s ideas in reconstructing the concept of anthropic time.

The currently leading cognitive theory of consciousness, Global Workspace Theory,1,2 postulates that the primary functions of consciousness include a global broadcast serving to recruit internal resources with which to deal with the current situation and to modulate several types of learning. In addition, conscious experiences present current conditions and problems to a "self" system, an executive interpreter that is identifiable with brain structures like the frontal lobes and precuneus.1Be it human, animal or artificial, an autonomous agent3 is said to be (...) functionally conscious if its control structure (mind) implements Global Workspace Theory and the LIDA Cognitive Cycle, which includes unconscious memory and control functions needed to integrate the conscious component of the system. We would therefore consider humans, many animals4 and even some virtual or robotic agents5,6 to be functionally conscious. Such entities may approach phenomenal consciousness, as found in human and other biological brains, as additional brain-like features are added.Here we argue that adding mechanisms to produce a stable, coherent perceptual field7 in a LIDA controlled mobile robot might provide a small but significant step toward phenomenal consciousness in machines.>8 We also propose that implementing several of the various notions of self in such a LIDA controlled robot may well prove another step toward phenomenal consciousness in machines.

Chimpanzee behaviour with mirrors makes it plausible that they can recognise themselves as themselves in mirrors, and so have a 'self-concept'. I defend this claim, and argue that roughly similar behaviour in pigeons, as reported, does not in fact make it equally plausible that they also have this mental capacity. But for all that it is genuine, chimpanzee self-consciousness may differ significantly from ours. I describe one possibility I believe consistent with the data, even if not very plausible: that the (...) chimpanzee is aware of itself only as a material being, and not as a subject of any psychological states. As I try to make clear, this possibility exists even if the chimpanzee has psychological states, and is aware of some of them. (shrink)

Medieval accounts of diachronically unified consciousness have been overlooked by contemporary readers, because medieval thinkers have a unique and unexpected way of setting up the problem. This paper examines the approach to diachronically unified consciousness that is found in Augustine’s and Aquinas’s treatments of memory. For Augustine, although the mind is “distended” by time, it remains resilient, stretching across disparate moments to unify past, present, and future in a single personal present. Despite deceptively different phrasing, Aquinas develops a remarkably similar (...) view when, in order to accommodate Aristotle’s view of memory to Augustine’s, he insists that an implicit self-awareness “time-stamps” all intellectual acts. According to their shared approach, diachronic unified consciousness is the result of the curious way in which the mind is both drawn into and transcends the temporal succession of its own acts.

For Brentano, an act of consciousness features a presentation of an object joined with an inner presentation – an ‘inner consciousness’ or inner awareness – of that object-presentation. On Mark Textor’s articulation of Brentano’s model, the act has the structure of a single experience directed upon a plurality, viz.: the object and the experience itself. I consider an alternative development of this Brentanian model. Drawing on Husserl’s part-whole ontology, I submit, the act itself has the structure of a whole formed (...) from two co-dependent parts, viz., the object-presentation and inner awareness of that presentation. Looking to Husserl’s analysis of inner time-consciousness, Textor proposes an enhancement of Brentano’s model of inner consciousness. On Textor’s model, inner awareness is such that one may be aware of one’s experience, in the stream of one’s consciousness, ‘without grasping any adumbrations [of the experience], but temporal ones’. I dig into Husserl’s doctrine of ‘abumbration’ (as where a tree is given visually with adumbrations of its shape on the back side, of its color in gradations, etc.). On my reconstruction, inner awareness of an experience presents the experience within a manifold of ‘adumbrated’ temporal retentions and protentions that place the experience in its stream of consciousness.

The hard problem of consciousness is about how we could explain in physicalist terms why we are conscious. The meta-problem of consciousness is about how we could explain why we have a hard problem of consciousness. In this note I argue that the phenomenal concept strategy can in principle provide a satisfactory solution to the meta-problem.

And why is there a subjective component to experience?). It is easy to see that the separation between Weak and Strong Artificial Consciousness mirrors the separation between the easy problems and the hard problems of consciousness.

Dreaming can be explained as the product of an interaction among memory processes, elaborative processes, and phenomenal awareness. A feedback circuit is activated by this interaction according to the associative links and the requirements of the dream scene. Recently, it has been hypothesized that a partial similarity exists between dreaming and mind wandering and that these two processes may involve the same neural default network. This commentary discusses the differences and similarities between phenomenal consciousness during dreaming and phenomenal consciousness during (...) mind wandering from the perspective of the “continuity” of engagement of cognitive systems. The greatest difference consists in the lack of reality testing during dreaming. Dream imagery is hallucinatory by nature. Consequently, the simulated world in dreams makes dream imagery more akin to perception. In contrast, the imagery of mind wandering is more similar to imagination. The level of meta-awareness is preserved more frequ... (shrink)

According to behavioural theories deriving from pragmatism, gestalt psychology, existentialism, and ecopsychology, knowledge about the world is gained by intentional action followed by learning. In terms of the neurodynamics described here, if the intending of an act comes to awareness through reafference, it is perceived as a cause. If the consequences of an act come to awareness through proprioception and exteroception, they are perceived as an effect. A sequence of such states of awareness comprises consciousness, which can grow in complexity (...) to include self-awareness. Intentional acts do not require awareness, whereas voluntary acts require self-awareness. Awareness of the action/perception cycle provides the cognitive metaphor of linear causality as an agency. Humans apply this metaphor to objects and events in the world to predict and control them, and to assign social responsibility. Thus, linear causality is the bedrock of technology and social contracts. Complex material systems with distributed non-linear feedback, such as brains and their neural and behavioural activities, cannot be explained by linear causality. They can be said to operate by circular causality without agency. The nature of self-control is described by breaking the circle into a forward limb, the intentional self, and a feedback limb, awareness of the self and its actions. The two limbs are realized through hierarchically stratified kinds of neural activity. Intentional acts are produced by the self-organized microscopic neural activity of cortical and subcortical components in the brain. Awareness supervenes as a macroscopic ordering state, that defers action until the self-organizing microscopic process has reached closure in reflective prediction. Agency, which is removed from the causal hierarchy by the appeal to circularity, re-appears as a metaphor by which events in the world are anthropomorphized, making them appear subject to human control.
