Theories of Consciousness, Miscellaneous

The most prominent theories of perceptual content are incapable of accounting for the phenomenal particularity of perceptual experience. This difficulty, or so I argue, springs from the absence of a series of distinctions that end up turning the problem apparently unsolvable. After briefly examining the main shortcomings of representationalism and naïve realism, I advance a proposal of my own that aims to make the trivial fact of perceptually experiencing a particular object as such philosophically unproblematic. Though I am well aware (...) of the sketchy and schematic way in which my proposal is advanced and the other alternatives are criticized, I hope this paper is still worth its ink at least insofar as it is capable of pointing to a novel and promising way out of old and resilient difficulties that have been haunting philosophers of perception. If not a fully developed theory, at least I deliver here a sketch that, or so I sell, is worth the bet. (shrink)

At the time of his death in May of 2012, Ralph Pred was working on a critical social theory inspired by process philosophy. In the book manuscript he left unfinished, Syntax and Solidarity, he develops a “radically empirical” sociology that enables him to identify and critically evaluate the different forms that social solidarity has taken in the history of civilization. The purpose of this paper is to draw attention to the importance of his unfinished project. The executors of Pred’s literary (...) estate would be happy to see his project, with due acknowledgment, publicized and continued. Keywords: Active Voice Bias, Concrescence, Middle Voice, Sociogeny, Solidarity, Substance. (shrink)

Sebastian Rödl portrays much of his work as attempts at articulating a German idealist view of self-consciousness. Although he rarely engages directly with German idealist texts, his accounts of first-person and second-person knowledge arrive at strikingly Fichtean theses regarding the necessary identity of subject and object in the former and the necessary reciprocity of subject and other in the latter. Despite this affinity, I argue, Rödl's accounts lack a feature that is essential to Fichte's and, indeed, to German idealism's distinctive (...) orientation: the thought of a first principle. I show that while second-person knowledge between subjects is genetically prior to self-consciousness—for Fichte as for Rödl—first-person knowledge of the I as first principle is systematically prior to self-consciousness—a point of architectonic and anti-nihilistic importance for Fichte, but which goes missing on Rödl's accounts, thereby obstructing their intended German idealist articulation.

A popular issue in mind is to explain why conscious mental states are conscious. Prinz (2012) defends three claims in an effort to make such an explanation: (i)mental states become conscious when and only when we attend to them; (ii)attention is a process by which mental states become available to working memory; so (iii) mental states are conscious when and only when they become available to working memory. Here I attack Prinz's theory, made explicit in (iii), by showing that there (...) is strong empirical reason to doubt each of the foregoing claims. I rehearse defenses of the claims Prinz has made, as well as possible replies he does not explicitly employ, and show how they are inadequate to save his view. (shrink)

The main aim of this paper is to show that we can extract an elaborate account of phe- nomenal consciousness from Leibniz’s (1646-1716) writings. Against a prevalent view, which attributes a higher-order reflection account of phenomenal consciousness to Leibniz, it is argued that we should understand Leibniz as holding a first-order concep- tion of it. In this conception, the consciousness aspect of phenomenal consciousness is explained in terms of a specific type of attention. This type of attention, in turn, is (...) accounted for in terms of cognitive appetites aiming at knowledge about a repre- sented object by means of initiating cognitive operations on representational content. Furthermore, against the view that Leibniz holds a reifying account, it is argued that Leibniz accepts an epistemic account of phenomenal character. According to this view, the phenomenal character of phenomenally conscious states rests on the con- fusing effect of imperfect acts of attention directed towards representational contents. Holding this view, Leibniz finds fruitful middle ground between contemporary stan- dard positions like higher-order theories, representationalist conceptions, and qualia accounts of phenomenal consciousness. His position possesses resources to meet sev- eral objections these standard accounts are confronted with. (shrink)

The Global Workspace Theory (GWT) proposed by Bernard Baars (1988) along with Daniel Dennett’s (1991) Multiple Drafts Model (MDM) of consciousness are renowned cognitive theories of consciousness bearing similarities and differences. Although Dennett displays sympathy for GWT, his own MDM does not seem to be fully compatible with it. This work discusses this compatibility, by asking if GWT suffers from Daniel Dennett’s criticism of what he calls a “Cartesian Theater”. We identified in Dennett 10 requirements for avoiding the Cartesian Theater. (...) We believe that some of these requirements are violated by GWT, but not all, hence there is partial incompatibility with MDM, and it is nonsense to answer if GWT is or is not a Cartesian Theater. However, by asking such question we conclude that the issues around this discussion involve fuzzy claims about degrees of consciousness and we show how the Neuro-Astroglial Interaction Model (NAIM) is fit for solving such conceptual issues.

Ockham holds what nowadays would be characterized as a “higher-order perception” theory of consciousness. Among the most common objections to such a theory is the charge that it gives rise to an infinite regress in higher-order states. In this paper, I examine Ockham’s various responses to the regress problem, focusing in particular on his attempts to restrict the scope of consciousness so as to avoid it. In his earlier writings, Ockham holds that we are conscious only of those states to (...) which we explicitly attend. This view, I go on to argue, is inadequate on both phenomenological and philosophical grounds. Interestingly, and perhaps for this very reason, in later works, Ockham goes on to develop an alternative explanation for his account of the limited scope of consciousness. (shrink)

Difficulties in distinguishing veridical reports of experience from confabulations have implications for theories of consciousness. I develop some of these implications through a consideration of out-of-body experiences (OBEs). Do these variations indicate individual variation in experience or are they post-hoc confabulations, stories told by subjects to themselves in an attempt to make sense of the core phenomenology? I argue that no existent or possible evidence would be sufficient to favour one hypothesis over the other. How such evidence is interpreted depends (...) on prior commitments to one or other of these hypotheses or to a theory of consciousness that is not neutral as to these hypotheses. One of these types of theory, namely vehicle theories, has difficulty accommodating the existence of confabulations and so allows for only the elaborate phenomenology hypothesis. Because we cannot know that reports are not confabulations, vehicle theories are insufficient to explain OBEs. (shrink)

The experience of embodiment may be studied using the rubber hand illusion. Little is known about the cognitive mechanism that elicits the feeling of embodiment. In previous models of the rubber hand illusion, bodily signals are processed sequentially. Such models cannot explain some more recent findings. Carruthers (2013) proposed a multidimensional model of embodiment, in which the processing of embodiment is understood in terms of conceptual hand space. Visual features of hands are represented along several dimensions. The rubber hand illusion (...) is then explained as the erroneous matching of the online representation of the artificial hand to the stored prototype in a space defined by those dimensions. We conducted the first experimental tests to investigate the multidimensional conceptual space account. First, participants performed a series of odd-one-out judgments for triads of hand images (including their own hand) and we then employed multidimensional scaling analyses. We found that a multidimensional model of perceived hand similarity could be fitted to our data. Second, we tested if a multisensory bodily signal manipulation (the rubber hand illusion) influences the position of the viewed artificial hand in hand space. We employed synchronous and asynchronous stroking and found that in the synchronous condition, which elicits the rubber hand illusion, compared to the asynchronous condition, which does not, the artificial hand was closer to the center of hand space; that is, to a prototype hand. We discuss these findings in the context of the Carruthers (2013) conceptual space model as well as other rubber hand illusion models. (shrink)

This festschrift commemorates the legacy of UK-based Portuguese sociologist Hermínio Martins (1934-2015). It introduces Martins’ wide-ranging contributions to the social sciences, encompassing seminal works in the fields of philosophy and social theory, historical and political sociology, studies of science and technology, and Luso-Brazilian studies, among others.

We review a rough scheme of quantum mechanics using the Clifford algebra. Following the steps previously published in a paper by another author [31], we demonstrate that quantum interference arises in a Clifford algebraic formulation of quantum mechanics. In 1932 J. von Neumann showed that projection operators and, in particular, quantum density matrices can be interpreted as logical statements. In accord with a previously obtained result by V. F Orlov , in this paper we invert von Neumann’s result. Instead of (...) constructing logic from quantum mechanics , we construct quantum mechanics from an extended classical logic. It follows that the origins of the two most fundamental quantum phenomena , the indeterminism and the interference of probabilities, lie not in the traditional physics by itself but in the logical structure as realized here by the Clifford algebra.

The subject of free will has suffered something of a renascence in recent popularized American philosophy. The issue is, of course, a Gordian knot of underlying metaphysical and ontological presupposition, in both the analytic and continental traditions. In this paper, I attempt a bit of an untangling, and in doing so, I find that the fundamental position of the contemporary champion of “no freedom” (Galen Strawson) is not only compatible with a radical Sartrean freedom, but that the two philosophers’ deeper (...) ontology is much the same, supports the same metaphysics and the same outline of an existentialist ethics. My approach is a combination of analytic and continental method and background: I continue to believe that there is no necessary separation between the analytic and continental camps, and that there is much to be gained from the reabsorption of analytic style into the broader philosophic tradition.

The component structures of two distinct neuropsychological systems are described. "System-Y" depends upon "system-X" which, on the other hand, can operate independently of system-Y. System-X provides a matrix upon which system-Y must operate, and, system-Y is transformed by the operations of system-X. In addition these neuropsychological structures reverberate in political history and in the cosmos. The most fundamental structure in the soul, in society, and in the cosmos, has the form of a conical spiral. It can be described mathematically as (...) an harmonic system and mythologically in terms of the birth, marriage and death of the divine-king. ;System-Y corresponds to the neocortex. System-X corresponds to the region below the cortex including the limbic brain. Many of the essential structures of system-Y are captured by Plato's image of the helmsman: orientation, locomotion, manual control and dexterity, visual guidance, verbal command, intention, and volition. System-X on the other hand has been systematically neglected by Western culture, beginning with Plato. ;The dissertation builds upon Yakovlev's distinction between "teleokinesis," "ectokinesis" and "endokinesis." "Teleokinesis" refers to goal-directed action in external space, and belongs to system-Y. Ectokinesis and endokinesis are components of system-X. "Endokinesis" refers to movements within the body. "Ectokinesis" refers to the emotions, which are expressions of endokinesis. The mechanics of ectokinesis is that of an harmonic or vibrational system, as is the mechanics of a musical instrument. ;Within a trance the structure of system-Y is temporarily altered, such that system-X enters the foreground of awareness. Because ectokinesis is analogous to music cultures inspired by trance experience understand the universe in terms of music. The structure of ectokinesis in a trance is that of a conical spiral. Plato inherited the mystical traditions of the ancient Near East but replaced the spiral of emotions with a spiral of ideas , by understanding the axis of the cone as the paradigmatic dimension, and the angular rotation of the spiral as the syntagmatic dimension, of language. Finally I explain how the mythology and political structure of theocratic society imitated the neuropsychological structures of trance experience. (shrink)

Mind, Consciousness and Body -/- We do not know how to think with or about these notions and others such as reality, perception, space, time, etc… In the following I will deal with the umbrella notions of mind, consciousness and body. The contents is relevant, but of greater importance is the manner or method in which I deal with these notions. I first present as an illustration of my approach or method, how I have dealt with the notions of intuition (...) and intuiting. One of the points I am trying to make is that: we do not know how to think about many things, for example mind, consciousness, awareness, body, intuition, etc. Therefore, I attempt to explore a number of things that we must investigate and deal with before we use these and other notions, as if they are clearly defined terms, before we try to use them to think and to think about anything, especially many leveled and multi- dimensional issues and problems such as the workings of ‘the mind, the body, intuition, consciousness and the relationship, if there are any, between these and other things. Then I suggest the initial steps for a few very basic requirements before the exploration of a theory of embodied, living, conscious tissues and a model for embodied (self-) consciousness research.

Integrated Information Theory (IIT) is one of the most influential theories of consciousness, mainly due to its claim of mathematically formalizing consciousness in a measurable way. However, the theory, as it is formulated, does not account for contextual observations that are crucial for understanding consciousness. Here we put forth three possible difficulties for its current version, which could be interpreted as a trilemma. Either consciousness is contextual or not. If contextual, either IIT needs revisions to its axioms to include contextuality, (...) or it is inconsistent. If consciousness is not contextual, then IIT faces an empirical challenge. Therefore, we argue that IIT in its current version is inadequate. (shrink)

In this paper, I respond to Kriegel’s criticism of McGinn’s mysterianism. Kriegel objects to a particular argument for the possibility of human cognitive closure and also gives a direct argument against mysterianism. I intend to show that neither the objection nor the argument is convincing.

Dr. Vukov analyzing patients with disorders of consciousness, proposed that medical well-regarded policy recommendations cannot be justified by looking solely to patients’ actual levels of consciousness (minimally conscious state – MCS versus vegetative state – VS), but that they can be justified by looking to patients’ potential for consciousness. One objective way to estimate this potential (actual physical possibility) is to consider a neurophysiologically informed strategy. Ideally such strategy would utilize objective brain activity markers of consciousness/unconsciousness. The Operational Architectonics (OA) (...) theory of brain-mind functioning is an example of such a strategy. Besides being mathematically simple, neurophysiologically accurate, and compatible with the cognitive/phenomenal perspectives on consciousness, application of OA strategy to quantitative EEG analysis of patients in VS and MCS revealed that the absence of consciousness in VS is paralleled by impairment of overall EEG operational architecture. Specifically, neuronal assemblies become smaller, their life span shortened, and they became highly unstable and functionally disconnected (desynchronized). At the same time, fluctuating (minimal) awareness in patients in MCS was paralleled by partial restoration of EEG operational architecture (increased size, life span, and stability of neuronal assemblies, together with an increased number and strength of functional connections among them), approaching the level found in healthy fully conscious participants. Moreover OA strategy to EEG analysis allowed predicting the emergence of consciousness in VS patients after six years following the brain trauma. Therefore, the OA methodology could reliably predict which patients may regain consciousness, and thus determine which patients may have the potential for consciousness. (shrink)

In Disturbed Consciousness, philosophers and other scholars examine various psychopathologies in light of specific philosophical theories of consciousness. The contributing authors—some of them discussing or defending their own theoretical work—consider not only how a theory of consciousness can account for a specific psychopathological condition but also how the characteristics of a psychopathology might challenge such a theory. Thus one essay defends the higher-order thought (HOT) theory of consciousness against the charge that it cannot account for somatoparaphrenia (a delusion in which (...) one denies ownership of a limb). Another essay argues that various attempts to explain away such anomalies within subjective theories of consciousness fail. -/- Other essays consider such topics as the application of a model of unified consciousness to cases of brain bisection and dissociative identity disorder; prefrontal and parietal underconnectivity in autism and other psychopathologies; self-deception and the self-model theory of subjectivity; schizophrenia and the vehicle theory of consciousness; and a shift in emphasis away from an internal (or brainbound) approach to psychopathology to an interactive one. Each essay offers a distinctive perspective from the intersection of philosophy, consciousness research, and psychiatry. -/- Contributors Alexandre Billon, Andrew Brook, Paula Droege, Rocco J.

We can divide philosophical theories of consciousness into two main camps: First-Order theories and Higher-Order theories. Like all Higher-Order theories, many First-Order theories are mentalistic theories of consciousness: they attempt to reduce a mental state’s being consciousness using mental (but non-phenomenal) terms, such as being available to certain cognitive centers. I argue that mentalistic First-Order theories, once fully cashed out, collapse into some form of Higher-Order theory. I contend that not only is there general considerations in favor of this conclusion, (...) but that the four most prominent mentalistic ‘First-Order’ theories are, in fact, Higher-Order theories in disguise. Given a strong assumption in favor of some form of mental ism, if this is right, what emerges is a powerful argument for the Higher-Order theory of consciousness. (shrink)

Quale sia la natura della coscienza è uno dei problemi più analizzati e discussi sia nella ricerca filosofica sia in quella scientifica. Ogni mese nel mondo vengono pubblicati diversi libri dedicati a questo argomento, e decine di riviste specialistiche ospitano articoli e saggi volti a chiarirne le varie componenti; sotto una tale pressione sono nate alcune riviste scientifiche dedicate esclusivamente all'argomento. A questo fiorire di ricerche corrisponde una quantità altrettanto elevata di approcci. Una rivista come il Journal of consciousness studies, (...) ad esempio, annovera contributi di filosofi e neurobiologi, scienziati cognitivi e psicologi gli uni accanto agli altri, a testimoniare proprio la varietà delle questioni e dei metodi di indagine che si addensano attorno ai fenomeni coscienti. Nel libro ho tenuto fede a questa molteplicità, descrivendo le principali teorie filosofiche accanto ai risultati empirici di psicologi e neurologi. Per ragioni di spazio e di taglio generale ho dovuto eliminare molto, e ogni volta penso a quanti autori e correnti di un certo rilievo ho dovuto tralasciare. Lo scopo principale di questo volume, tuttavia, non è quello dell'esaustività, quanto piuttosto di fornire un quadro per chi voglia orientarsi nel problema della coscienza, purché sia attrezzato di una buona dose di curiosità e di un po' di tenacia per poter affrontare qualche dettaglio più tecnico; non è dunque una summa enciclopedica di quel che si studia oggi sotto l'etichetta “coscienza”. Con questo spirito ho descritto, nel primo capitolo, le radici filosofiche del problema della coscienza rifacendomi a molti classici, alcuni dei quali davvero sorprendentemente attuali. Nel capitolo successivo ho analizzato i diversi risultati empirici sui quali si stanno costruendo le teorie più interessanti; il terzo capitolo presenta una serie di teorie filosofiche volte a difendere l'autonomia della coscienza dalle spiegazioni naturalistiche, e il filosofo David Chalmers fa la parte del campione di questo schieramento. L'ultimo capitolo propone invece le teorie più marcatamente naturalistiche, ed è il filosofo Daniel Dennett a portare il vessillo del rappresentante. I quattro capitoli che compongono il libro, dunque, alternano l'approccio filosofico, dedito a chiarire i presupposti concettuali, e quello naturalistico ed empirico, basato sulle tecniche sperimentali, per rendere conto proprio della varietà del problema coscienza, e di come esso rappresenti forse l'ultima frontiera con la quale noi esseri umani proviamo a ritagliarci un posto speciale tra ciò che ci circonda. È sufficiente volgersi alla storia della scienza per constatare le radici di una simile esigenza. Galileo Galilei ha spostato il nostro pianeta dal centro del cosmo ad una marginale periferia; Charles Darwin ci ha inserito, esseri naturali ed emotivi, nel mondo biologico al pari di ogni altra specie; Alan Turing, infine, ha mostrato che molta della nostra cognizione può essere trattata con metodi computazionali. La coscienza sembra l'ultimo baluardo che separa, categorialmente se non ontologicamente, la nostra specie da tutto il resto. L'eventualità di tradurla in termini neurobiologici è da molti considerata una chimera, e la liceità di una simile ipotesi è posta sotto scrutinio per evidenziarne i presupposti filosofici. Questo testo dovrebbe aiutare a capire quali sono gli snodi del problema e chi ha buone prospettive di cogliere nel segno. (shrink)

What is it that makes a mental state conscious? Recent commentators have proposed that for Kant, consciousness results from differentiation: A mental state is conscious insofar as it is distinguished, by means of our conceptual capacities, from other states and/or things. I argue instead that Kant’s conception of state consciousness is sensory: A mental state is conscious insofar as it is accompanied by an inner sensation. Interpreting state consciousness as inner sensation reveals an underappreciated influence of Crusius on Kant’s view, (...) solves some long-standing puzzles concerning Kant’s difficult doctrine of self-affection, and sheds light on his theory of inner experience.

Introspective and phenomenological methods are once again being used to support the use of subjective reports, rather than objective behavioural measures, to investigate and measure consciousness. Objective measures are often seen as useful ways of investigating the range of capacities subjects have in responding to phenomena, but are fraught with the interpretive problems of how to link behavioural capacities with consciousness. Instead, gathering subjective reports is seen as a more direct way of assessing the contents of consciousness. This article explores (...) three different ways of gathering subjective reports that have been discussed in recent literature on consciousness, including immediate retrospection (Schwitzgebel [2007]) and two types of introspective training (Overgaard et al. [2004]; Schwitzgebel [2008]). Although not an exhaustive survey of the range of introspective methods now used, the discussion below highlights a range of general methodological problems with introspective methods, many identified up to a century ago. It is argued that none of the methodological problems established in earlier criticisms of the use of subjective reports have been dealt with, yet are still valid criticisms. Given that this is not the first time proponents of introspective, subjective measures of conscious have failed to answer these criticisms, this raises the question of whether the goal of providing a measure of consciousness is a methodological muddle worth pursuing.

Abstract: The article considers how the relationship between consciousness and neural events in the brain should be viewed. The approach is that conscious experiences – perceptions, feelings and mental images – are the subjective versions of the neural events. It is the conscious experiences that are the essence of intentionality and meaning; the neural events do the causative work. From this viewpoint there are discussions of the neural representations that figure in thinking and their corresponding subjective experiences – in what (...) way neural events can be the representations of things in the world and the body, and how the subjectivity of conscious experiences converts causation into intentionality. Finally the article seeks to explain how, if consciousness has no causative efficacy, we can think about it at all, including a discussion of “zombies”, and discusses whether machines can think or be conscious..

This article is not an attempt to explain consciousness in terms basically of quantum physics or neuro-biology. Instead I should like to place the term "Consciousness" on a broader footing. I shall therefore proceed from everyday reality, precisely where we experience ourselves as conscious beings. I shall use the term in such a general way as to resolve the question whether only a human being enjoys consciousness, or even a thermostat. Whilst the difference is considerable, it is not fundamental. Every (...) effect exists in the perception of a consciousness. I elaborate on its freedom of choice, in my view the most important source of creativity, in a similarly general way. The problems associated with a really conscious decision do not disappear by mixing determination with a touch of coincidence. Both must enter into a higher unity. In so doing it will emerge that a certain degree of freedom of choice is just as omnipresent as consciousness - an inherent part of reality itself. (shrink)

Przedmiotem artykułu jest krytyczna analiza teorii świadomości rozumianej jako dwuczłonowa relacja asymetryczna. Koncepcja taka została sformułowana przez Paula Natorpa w Allgemeine Psychologie nach kritischer Methode. Według tej teorii świadomość nie jest ani aktem, ani czynnością, ani stanem, lecz czystym stosunkiem podmiotu do przedmiotu. Świadomość jako relacja różnicująca jest w tym ujęciu relacją asymetryczną, to znaczy, że nie można podmiotu ująć jako przedmiotu i odwrotnie, czyli tylko przedmiot może być uświadomiony przez podmiot.

It is not necessarily the case that we ever have experiences of self, but human beings do regularly report instances for which self is experienced as absent. That is there are times when body parts, mental states, or actions are felt to be alien. Here I sketch an explanatory framework for explaining these alienation experiences, a framework that also attempts to explain the “mental glue” whereby self is bound to body, mind, or action. The framework is a multi-dimensional model that (...) integrates personal and sub-personal components, psychological and neural processes. I then proceed to show how this model can be applied to explain the action-related passivity experiences of persons suffering from schizophrenia. I argue that a distinctive phenomenological mark of these experiences is that they are vividly felt, unlike ordinary actions (those taken to belong to self), and I seek to explain these heightened sensory experiences from within the proposed framework. I also propose hypotheses concerning such phenomena as thought insertion and anarchic hand syndrome that are motivated by this framework. Finally, I argue that the proposed model and view of self-experiences is consistent with several aspects of and theories of consciousness, especially theories which indicate that consciousness is more likely to be engaged when we are dealing with novelty or error—e.g. when self seems to have gone missing. I conclude by recommending that if we wish to learn about self, we would be well advised to attend closely to those times when it seems absent. (shrink)

Some philosophers suggest that a minimal form of self-awareness is an integral element of the way in which all experiences are given (SPC: self-presenting claim). The main argument for this is that the phenomenological quality of ‘mineness’ of the experience reveals the self as a part of all experiences. Since the sense of mineness is taken as intrinsic to the givenness of the experience, it counts as an argument for the SPC. In this essay, I assess this claim and its (...) main argument. After describing the phenomenological approach to self- awareness that grounds the discussion, I comment on some pathological cases that challenge the SPC. After this, I examine the standard reply in defence of the SPC and I focus the discussion on cases of thought insertion. I conclude that although the standard reply adds interesting elements to the general discussion, it becomes philosophically problematic especially when it tries to deal with cases of thought insertion.

A review of Thomas Natsoulas's "Consciousness and Perceptual Experience.".

In this paper I argue that neuroscience has been harmed by the widespread adoption of seriously inadequate methodologies or philosophies of science - most notably inductivism and falsificationism. I argue that neuroscience, in seeking to understand the human brain and mind, needs to follow in the footsteps of evolution.

I highlight a neglected but striking phenomenological fact about our experiences: they have a pervasively spatial character. Specifically, all (or almost all) phenomenal qualities – roughly, the introspectible, philosophically puzzling properties that constitute ‘what it’s like’ to have an experience – introspectively seem instantiated in some kind of space. So, assuming a very weak charity principle about introspection, some phenomenal qualities are instantiated in space. But there is only one kind of space – the ordinary space occupied by familiar objects. (...) And the only objects appropriately located in ordinary space are outside the subject’s mind. This entails experiential externalism, the view that at least one phenomenal quality is instantiated outside the subject’s mind. Experiential externalism is incompatible with many leading theories of experience, including certain mental paint theories; some forms of representationalism; paradigmatic versions of sense-datum theory; and views on which no phenomenal qualities are instantiated. My argument is structurally similar to familiar arguments based on the ‘transparency of experience.’ However, I suggest, phenomenological intuitions about spatiality are considerably more stable than phenomenological intuitions about transparency. For many philosophers, transparency intuitions fade markedly with respect to non-standard experiences, including experiences associated with blurry or double vision. But spatiality intuitions remain robust even for these experiences. Thus, spatiality intuitions should be more dialectically effective than transparency intuitions for supporting experiential externalism. (shrink)

It is pretty obvious to most of us that self-consciousness is a product of evolution. But its nature is unknown. We propose here a scenario addressing a possible evolutionary nature of self-consciousness covering the segment linking pre-human primates to humans. The scenario is based on evolutions of representations and of inter-subjectivity that could have taken place within the minds of our pre-human ancestors . We begin by situating self-consciousness relatively to other aspects of human consciousness. With the help of anthropology, (...) we date a possible starting point of our scenario at a time when our non self-conscious pre-human ancestors were able to build meaningful representations and were capable of inter-subjectivity, like are our today modern apes. As the proposed scenario is based on an evolution of representations, we recall an existing model for meaningful representations based on the generation of meaningful information by systems submitted to internal constraints. This model allows us to define representations of conspecifics and auto-representations that we assume as having been present in the minds of our pre-human ancestors. The next step of the scenario is to consider an evolution of inter-subjectivity towards identification with conspecifics that could have led to a merger of the auto-representation with the representations of conspecifics in the minds of our ancestors. Such a merger brought the auto-representation to become about an entity existing in the environment, as were the representations of conspecifics. We consider that such identification with conspecifics has introduced in the mind of our ancestors an elementary and embryonic sense of being an existing entity that we name ‘ancestral self-consciousness’. The same process has also imposed to our ancestors an identification with suffering or endangered conspecifics which has produced an important anxiety increase that could have blocked the evolutionary process. We propose that the performances developed by our ancestors to manage that anxiety increase have also generated significant evolutionary advantages that have helped the development of ancestral self-consciousness and favored its evolution toward our full-fledged self-consciousness. It is also proposed that some pre-human primates have avoided the anxiety increase by finding a niche where evolutionary advantages were not necessary. This may have led to our today apes. The contribution of anxiety to the proposed scenario brings to position anxiety management as having guided the evolution of self-consciousness and as still being a key player in our today human minds. Regarding philosophy of mind, possible links between phenomenal consciousness and the proposed nature of self-consciousness are introduced. The conclusion presents a summary of the points addressed here. Possible continuations are highlighted as related to human mind, to anxiety management and to artificial intelligence. (shrink)

Meanings are present everywhere in our environment and within ourselves. But these meanings do not exist by themselves. They are associated to information and have to be created, to be generated by agents. The Meaning Generator System (MGS) has been developed on a system approach to model meaning generation in agents following an evolutionary perspective. The agents can be natural or artificial. The MGS generates meaningful information (a meaning) when it receives information that has a connection with an internal constraint (...) to which the agent is submitted. The generated meaning is to be used by the agent to implement actions aimed at satisfying the constraint. We propose here to highlight some characteristics of the MGS that could be related to items of philosophy of information. (shrink)

Evolutionary advantages of consciousness and intersubjectivity are part of current philosophical debates on the nature of consciousness. Both are linked and intersubjectivity is sometimes considered as a form of consciousness [1]. Regarding the evolution of consciousness, studies tend to focus on phenomenal consciousness [2]. We would like here to bring the focus on self-consciousness and continue the build up of a corresponding evolutionary scenario. We also propose to introduce a possible evolutionary link between self-consciousness and phenomenal consciousness. Our starting point (...) is the evolutionary scenario based on the evolution of intersubjectivity that goes thru the identification with conspecifics at pre-human primate time frame [3, 4, 5]. The scenario considers that such identification with conspecifics brought the non self-conscious auto-representation carried by our prehuman primate ancestors to merge with the representations of conspecifics. The latter transferred to the auto-representation the characteristics of an entity existing in the environment, and by this way introduced some first elements of self-consciousness for our pre-human ancestors. In addition, an anxiety increase coming from the identification with suffering or endangered conspecifics produced an evolutionary engine based on anxiety limitation. We want here to complement this evolutionary approach by introducing the improvement of action programs as a contributor to the evolutionary advantages of intersubjectivity and self-consciousness. We look at the possibility for a subject to improve the action programs that conspecifics implement. The performance of identification with conspecifics allows the subject to consider that errors made by conspecifics are potentially her own errors, and consequently allows the subject to correct the errors of conspecifics for her own benefit. We describe the process of non successful action identification from the perspective of an observer and present the synergetic action program improvements with their contribution to the evolution of intersubjectivity and self-consciousness. We add this contribution to the existing evolutionary scenario on self-consciousness and introduce a possible evolutionary link between self-consciousness and phenomenal consciousness. We use for that the relation existing between phenomenal consciousness and pre-reflexive self-consciousness [6] and propose to link the latter to the proposed evolutionary nature of self-consciousness. We finish by summarizing the points addressed and by introducing some possible continuations. (shrink)

This paper uses a paradox inherent in any solution to the Hard Problem of Consciousness to argue for God’s existence. The paper assumes we are “thought machines”, reading the state of a relevant physical medium and then outputting corresponding thoughts. However, the existence of such a thought machine is impossible, since it needs an infinite number of point-representing sensors to map the physical world to conscious thought. This paper shows that these sensors cannot exist, and thus thought cannot come solely (...) from our physical world. The only possible explanation is something outside, argued to be God. (shrink)

Este artigo pretende caracterizar de forma geral os posicionamentos fisicalistas na filosofia da mente e indicar como a questão do livre-arbítrio surge e pode ser crucial para tal corrente de pensamento. Primeiramente pretende mostrar a diferença entre a posição reducionista e a não-reducionista e depois salientar suas potencialidades e dificuldades na abordagem da questão do livre-arbítrio. Enfim, mesmo que a questão ainda fique em aberto, verificar-se-á que o livre-arbítrio parece não encontrar espaço no cenário apresentado pelas correntes fisicalistas.

Giulio Tononi (2008) has offered his integrated information theory of consciousness (IITC) as a “provisional manifesto.” I critically examine how the approach fares. I point out some (relatively) internal concerns with the theory and then more broadly philosophical ones; finally I assess the prospects for IITC as a fundamental theory of consciousness. I argue that the IITC’s scientific promise does carry over to a significant extent to broader philosophical theorizing about qualia and consciousness, though not as directly as Tononi suggests, (...) since the account is much more focused on the qualitative character of experience rather than on consciousness itself. I propose understanding it as “integrated information theory of qualia” (IITQ), rather than of consciousness. (shrink)

A brief article reviewing the links between emotion, cognition, mental processes and images and the nature of cognitive thought in consciousness.

Two of the most important concepts in contemporary philosophy of mind are computation and consciousness. This paper explores whether there is a strong relationship between these concepts in the following sense: is a computational theory of consciousness possible? That is, is the right kind of computation sufficient for the instantiation of consciousness. In this paper, I argue that the abstract nature of computational processes precludes computations from instantiating the concrete properties constitutive of consciousness. If this is correct, then not only (...) is there no viable computational theory of consciousness, the Human Mental State Multiple Realizability in Silicon Thesis is almost certainly false. (shrink)

Our engagement with time is a ubiquitous feature of our lives. We are aware of time on many scales, from the briefest flicker of change to the way our lives unfold over many years. But to what extent does this encounter reveal the true nature of temporal reality? To the extent that temporal reality is as it seems, how do we come to be aware of it? And to the extent that temporal reality is not as it seems, why does (...) it seem that way? These are the central questions addressed by Simon Prosser in Experiencing Time. He defends the B-theory of time, according to which the apparently dynamic quality of change, the special status of the present, and even the passage of time are all illusions. Prosser goes on to explore solutions to certain puzzles raised by experiences of temporal features such as changes, rates, and durations, and in doing so sheds light on broader issues in the philosophy of mind.

Soonya Vaada, the prime and significant contribution to Indian philosophical thought from Buddhism will be scientifically developed and presented. How this scientific understanding helped to sow seeds of origin of rationalism and its development in Buddhist thought and life will be delineated. Its role in the shaping of Buddhist and other Indian philosophical systems will be discussed. Its relevance and use in the field of cognitive science and development of theories of human consciousness and mind will be put forward. The (...) idea of absence as zero in number system, vacuum in physics and other natural sciences and state of absence of cognition in mind machine modeling will be presented. The use of significance of Soonya Vaada in philosophy, rational social life, natural sciences and technology, mathematics and cognitive science will be comprehensively discussed and a model for human cognition and communication will be arrived at. -/- .

Colours and consciousness both present us with metaphysical problems. But what exactly are the problems? According to standard accounts, they are roughly the following. On the one hand, we have reason to believe, about both colour and consciousness, that they are identical with some familiar natural phenomena. But on the other hand, it is hard to see how these identities could obtain. I argue that this is an adequate characterisation of our metaphysical problem of colour, but a mischaracterisation of the (...) problem of consciousness. It mischaracterises the problem by presenting consciousness as more 'colour-like' than we have reason to take it to be. The real problem of consciousness is, I suggest, that almost nothing theoretically useful is known about this phenomenon at present. I also explore some implications of this perspective on the problem of consciousness. Given the shape of the problem, I argue that we can't rule out all forms of eliminativism about consciousness. Nor can we rule out that future research will close the ' explanatory gap' that consciousness gives rise to. (shrink)

My paper consists of five parts. In the first part I explain what I mean by the phenomenology of mind. In the second part I show that in contemporary analytic philosophy the prevailing metaphysical theories of the mind are typically not connected to the phenomenology of mind. Views on the nature of the mind are developed without considering the phenomenological facts. In the third part I outline a notion of metaphysics connected to the phenomenology of mind, then in the fourth (...) and fifth parts I give some examples to illustrate how I envision the nature of this connection.
