Over a decade ago, I introduced a large-scale theory of the cognitive brain which explained for the first time how the human brain is able to create internal models of its intimate world and invent models of a wider universe. An essential part of the theoretical model is an organization of neuronal mechanisms which I have named the Retinoid Model (Trehub, 1977, 1991). This hypothesized brain system has structural and dynamic properties enabling it to register and appropriately integrate disparate (...) foveal stimuli into a perspectival, egocentric representation of an extended 3D world scene including a neuronally-tokened locus of the self which, in this theory, is the neuronal origin of retinoid space. As an integral part of the larger neuro-cognitive model, the retinoid system is able to perform many other useful perceptual and higher cognitive functions. In this paper, I draw on the hypothesized properties of this system to argue that neuronal activity within the retinoid structure constitutes the phenomenal content of consciousness and the unique sense of self that each of us experiences. -/- Trehub, A.

According to Uriah Kriegel’s self-representational theory of consciousness, mental state M is conscious just in case it is a complex with suitably integrated proper parts, M1 and M2, such that M1 is a higher-order representation of lower-order representation M2. Kriegel claims that M thereby “indirectly” represents itself, and he attempts to motivate this claim by appealing to what he regards as intuitive cases of indirect perceptual and pictorial representation. For example, Kriegel claims that it’s natural to say that (...) in directly perceiving the front surface of an apple one thereby perceives the apple itself. Cases such as this are supposed to provide intuitive support for the principle that if X represents Y, and Y is highly integrated into complex object Z, then X indirectly represents Z. In this paper I provide counterexamples to Kriegel’s principle of indirect representation, before going on to argue that we can explain what is going on in those cases in which the subject seems to represent a complex whole by representing one its parts without positing indirect representations anyway. I then argue that my alternative approach is superior to Kriegel’s in a number of ways, thereby rendering his theory of consciousness implausible. (shrink)

Advocates of the computational theory of mind claim that the mind is a computer whose operations can be implemented by various computational systems. According to these philosophers, the mind is multiply realisable because—as they claim—thinking involves the manipulation of syntactically structured mental representations. Since syntactically structured representations can be made of different kinds of material while performing the same calculation, mental processes can also be implemented by different kinds of material. From this perspective, consciousness plays a minor role (...) in mental activity. However, contemporary neuroscience provides experimental evidence suggesting that mental representations necessarily involve consciousness. Consciousness does not only enable individuals to become aware of their own thoughts, it also constantly changes the causal properties of these thoughts. In light of these empirical studies, mental representations appear to be intrinsically dependent on consciousness. This discovery represents an obstacle to any attempt to construct an artificial mind. (shrink)

The possibility of empirical test is discussed with respect to three issues: (1) What is the ontological relationship between consciousness and the brain/physical world? (2) What physical characteristics are associated with the mind/brain interface? (3) Can consciousness act on the brain independently of any brain process?

This article explores whether theory-ladenness makes empirical testing an inse cure foundation for objectivity. Specifically, this article uses path diagrams as visual heuristics to assist in (1) developing a parsimonious representation of the traditional empiricist view of empirical testing, (2) showing how the "New Image" view ostensibly threatens the objectivity of science, (3) proposing a unified, realist theory of empirical testing, (4) developing a representation of the unified theory, (5) exploring several potential threats to (...) objectivity, (6) discussing the proposed theory's implications for social science, and (7) adumbrating three foundational premises for scientific realism.

It is fairly common in the modern debates over qualia to find assumptions being made about the views of non-philosophers. It is often assumed that the concept is part of the folk theory of consciousness. In fact, even prominent skeptics about qualia will admit that their views run counter to common sense. I illustrate this by considering the work of Daniel Dennett, focusing on his standard articulation of the debate concerning his heterophenomenological method. While Dennett is often accused (...) of not going far enough (excluding qualia from the catalog of what needs to be explained by a science of consciousness), I argue that he goes too far in accepting that folk psychological utterances should be interpreted in terms of beliefs about qualia. I support this contention by calling on the results of six empirical studies testing Dennett’s theory of the folk theory of consciousness. (shrink)

Conscious experience is one of the most difficult and thorny problems in psychological science. Its study has been neglected for many years, either because it was thought to be too difficult, or because the relevant evidence was thought to be poor. Bernard Baars suggests a way to specify empirical constraints on a theory of consciousness by contrasting well-established conscious phenomena - such as stimulus representations known to be attended, perceptual, and informative - with closely comparable unconscious ones (...) - such as stimulus representations known to be preperceptual, unattended, or habituated. Adducing data to show that consciousness is associated with a kind of global workplace in the nervous system, and that several brain structures are known to behave in accordance with his theory, Baars helps to clarify many difficult problems.

It is usually taken as given that consciousness involves superior or more elaborate forms of information processing. Contemporary models equate consciousness with global processing, system complexity, or depth or stability of computation. This is in stark contrast with the powerful philosophical intuition that being conscious is more than just having the ability to compute. I argue that it is also incompatible with current empirical findings. I present a model that is free from the strong assumption that (...) class='Hi'>consciousness predicts superior performance. The model is based on Bayesian decision theory, of which signal detection theory is a special case. It reflects the fact that the capacity for perceptual decisions is fundamentally limited by the presence and amount of noise in the system. To optimize performance, one therefore needs to set decision criteria that are based on the behaviour, i.e. the probability distributions, of the internal signals. One important realization is that the knowledge of how our internal signals behave statistically has to be learned over time. Essentially, we are doing statistics on our own brain. This ‘higherorder’ learning, however, may err, and this impairs our ability to set and maintain optimal criteria for perceptual decisions, which I argue is central to perception consciousness. I outline three possibilities of how conscious perception might be affected by failures of ‘higher-order’ representation. These all imply that one can have a dissociation between consciousness and performance. This model readily explains blindsight and hallucinations in formal terms, and is beginning to receive direct empirical support. I end by discussing some philosophical implications of the model.

This work advances a theory in the metaphysics of phenomenal consciousness, which the author labels “e-physicalism”. Firstly, he endorses a realist stance towards consciousness and physicalist metaphysics. Secondly, he criticises Strong AI and functionalist views, and claims that consciousness has an internal character. Thirdly, he discusses HOT theories, the unity of consciousness, and holds that the “explanatory gap” is not ontological but epistemological. Fourthly, he argues that consciousness is not a supervenient but an emergent (...) property, not reducible and endowed with original causal powers, with respect to the micro-constituents of the conscious entity. Fifthly, he addresses the “zombie argument” and the “supervenience argument” within the e-physicalism framework. Finally, he elaborates on the claim that phenomenal properties are physical and discusses the “knowledge argument”. (shrink)

The concept of pluralism in corporate governance is stated as an emergent theory. Grounded in the concept of enhancing the input of various stakeholders and lessening the control of managers in corporate governance, the theory is the foundation of proposed legal changes in corporate governance and the board of directors. While more pluralistic control has been conceptually linked to improved social performance of the firm, this proposition is not supported in an empirical investigation.

The connectionist vehicle theory of phenomenal experience in the target article identifies consciousness with the brain’s explicit representation of information in the form of stable patterns of neural activity. Commentators raise concerns about both the conceptual and empirical adequacy of this proposal. On the former front they worry about our reliance on vehicles, on representation, on stable patterns of activity, and on our identity claim. On the latter front their concerns range from the general plausibility of a (...) vehicle theory to our specific attempts to deal with the dissociation studies. We address these concerns, and then finish by considering whether the vehicle theory we have defended has a coherent story to tell about the active, unified subject to whom conscious experiences belong.

It is not uncommon to find assumptions being made about folk psychology in the discussions of phenomenal consciousness in philosophy of mind. In this article I consider one example, focusing on what Dan Dennett says about the “folk theory of consciousness.” I show that he holds that the folk believe that the sensory qualities that we are acquainted with in ordinary perception are phenomenal qualities. Nonetheless, the shape of the folk theory is an empirical matter (...) and in the absence of empirical investigation there is ample room for doubt. Fortunately, experimental evidence on the topic is now being produced by experimental philosophers and psychologists. This article contributes to this growing literature, presenting the results of six new studies on the folk view of colors and pains. I argue that the results indicate against Dennett’s theory of the folk theory of consciousness. (shrink)

The so-called 'higher-order thought' (HOT) theory of consciousness says that what makes a mental state conscious is the presence of a suitable higher-order thought directed at it (Rosenthal, 1986; 1990; 1993; 2002; 2004; Gennaro, 1996; 2004). The HOT theory has been or could be attacked from two apparently opposite directions. On the one hand, there is what Stubenberg (1998) has called 'the problem of the rock' which, if successful, would show that the HOT theory proves too (...) much. On the other hand, it might also be alleged that the HOT theory does not or cannot address the so-called 'hard problem' of phenomenal consciousness. If so, then the HOT theory would prove too little. We might say, then, that the HOT theory is arguably between a rock and a hard place. In this paper, I critically examine these objections and defend the HOT theory against them. In doing so, I hope to show that the HOT theory, or at least some version of it, neither proves too little nor too much, but is just right. I also show that these two objections are really just two sides of the same coin, and that the HOT theory is immune from David Chalmers' (1995; 1996) criticisms of other attempted reductionist accounts of consciousness.

from non-conscious components by positing that consciousness is a universal primitive. For example, the double aspect theory of information holds that infor- mation has a phenomenal aspect. How then do you get from phenomenal infor- mation to human consciousness? This paper proposes that an entity is conscious to the extent it amplifies information, first by trapping and integrating it through closure, and second by maintaining dynamics at the edge of chaos through simul- taneous processes of divergence and (...) convergence. The origin of life through autocatalytic closure, and the origin of an interconnected worldview through conceptual closure, induced phase transitions in the degree to which informa- tion, and thus consciousness, is locally amplified. Divergence and convergence of cognitive information may involve phenomena observed in light e.g. focusing, interference, and resonance. By making information flow inward- biased, clo- sure shields us from external consciousness; thus the paucity of consciousness may be an illusion. (shrink)

Quantum mechanics unites epistemology and ontology: it brings human knowledge explicitly into physical theory, and ties this knowledge into brain dynamics in a causally efficacious way. This development in science provides the basis for a natural resolution of the dualist functionalist controversy, which arises within the classical approach to the mind brain system from the fact that the phenomenal aspects are not derivable from the principles of classical mechanics. A conceptually simple causal quantum mechanical theory of the mind/brain (...) is described, and used to examine the necessity and function of consciousness in brain process. (shrink)

I make three points about Searle’s philosophical work on consciousness and intentionality. First, I comment on Searle’s presentation and paper “The Problems of Consciousness.” I show that one of Searle’s philosophical claims about the relation between consciousness and intentionality appears to conflict with a demand he makes on acceptable empirical theories of the brain. Second, I argue that closer attention to the difference between conceptual connections and empirical connections corrects and improves Searle’s response to the (...) so-called “Logical Connections” argument, the argument that claims that mental states cannot be causes, since they are conceptually connected with actions. Third, I give a formulation of his Chinese Room argument that avoids some tempting responses. (shrink)

A new phenomenological framework for the characterization of human consciousness is presented. The theory is introduced in several stages - making distinctions concerning types of consciousness, levels, parameters, functional features and dynamic operations. The phenomenology encompasses both ordinary and non-ordinary states of mind. It appears that in its totality the phenomenology of human consciousness comprises a well- structured system exhibiting coherence and internal structure. In addition, this framework presents a new approach for cognitive research, methodologically as (...) well as theoretically. Observations concerning the intellectual challenge of consciousness are.

Charles Darwin is generally credited with having formulated the first systematic attempt to explain the evolutionary origins and function of the expression of emotions in animals and humans. His ingenious theory, however, was burdened with popular misconceptions about human phylogenetic heritage and bore the philosophical and theoretical deficiencies of the brain science of his era that his successors strove to overcome. In their attempts to rectify Darwin?s errors, William James, James Mark Baldwin and John Dewey each made important contributions (...) to a theory of emotion, which attempted to put it on a more secure philosophical and scientific footing. My contention is that Dewey and his collaborator, infant experimentalist Myrtle McGraw, succeeded where their contemporaries failed. They pointed the way out of the morass of recapitulationism, and showed how a developmental theory of consciousness, mind and emotion could be formulated that avoided the epistemological and ontological pitfalls of Darwin?s theory. Drawing on an extensive body of research from contemporary experimental studies of infant development, this essay attempts to put the questions raised by these historical figures about the structure, function and value of emotions in a theoretical framework. A developmental theory is proposed about the complex, interacting neurobiological and neurobehavioral factors that contribute to human emotional development. This theory identifies the possible relationships among emotions, consciousness and mind and how their co-development influences the capacity of young children to form moral judgments. (shrink)

This book offers a comprehensive analysis and re-evaluation of Hume's Treatise of Human Nature. Kant viewed Hume as the sceptical destroyer of metaphysics. Yet for most of this century the consensus among interpreters is that for Hume scepticism was a means to a naturalistic, anti-sceptical end. The author seeks here to achieve a balance by showing how Hume's naturalism leads directly to a kind of scepticism even more radical than Kant imagined. In the process it offers the first systematic treatment (...) of Humean associationalist psychology, including detailed exploration of his views on time-consciousness, memory, aspect-seeing, and the comparison with animal reason. Within this framework, Hume's views on language, belief, induction, causality, and personal identity emerge in a novel and revealing light. (shrink)

This paper develops an empirically motivated theory of visual consciousness. It begins by outlining neuropsychological support for Jackendoff's (1987) hypothesis that visual consciousness involves mental representations at an intermediate level of processing. It then supplements that hypothesis with the further requirement that attention, which can come under the direction of high level representations, is also necessary for consciousness. The resulting theory is shown to have a number of philosophical consequences. If correct, higher-order thought accounts, the (...) multiple drafts account, and the widely held belief that sensation precedes perception will all be found wanting. The theory will also be used to illustrate and defend a methodology that fills the gulf between functionalists who ignore the brain and neural reductionists who repudiate functionalism. (shrink)

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory of (...) personal identity. But the former stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

This paper examines some of the central arguments of John McDowell's Mind and World, particularly his treatment of the Kantian themes of the spontaneity of thought and of the nature of self-consciousness. It is argued that in so far as McDowell departs from Kant, his position becomes less plausible in three respects. First, the space of reason is identified with the space of responsible and critical freedom in a way that runs together issues about synthesis below the level of (...) concepts and at the level of complete judgements. This leads to the unwarranted exclusion of animal minds from the space of reasons. Second, McDowell draws no essential distinction between apperception and inner sense, a distinction which is important to a defensible Kantian view and to the very idea of a sui generis transcendental knowledge of the mind that is consistent with Kant's critical principles. McDowell does not take into account some of Kant's developed arguments about the inherently reflective nature of consciousness which is interpreted as an adverbial theory of the nature of conscious experience, a mode of being in a mental state (so neither an intrinsic nor extrinsic property of it). Third, McDowell endorses a standard treatment of Kant's approach to the mind in which a merely formal account of mind needs to be anchored outside consciousness on the physical body. The arguments for this conclusion, both in Mind and World and in related work by Bermudez and Hurley, is shown to be very inconclusive as a criticism of Kant. The capacity to self-ascribe thoughts that are already conscious shows, but does not say, a truth about the unity of our conscious experience that does not require further anchoring on a physical body; at that stage of the Critique Kant is describing conditions for conscious experience in general, not the conscious experience of spatio-temporally located makers of judgements. The alleged lacuna in Kant's arguments is no lacuna at all. (shrink)

In the physical sciences a rigorous theory is a hierarchy of descriptions in which causal relationships between many general types of entity at a phenomenological level can be derived from causal relationships between smaller numbers of simpler entities at more detailed levels. The hierarchy of descriptions resembles the modular hierarchy created in electronic systems in order to be able to modify a complex functionality without excessive side effects. Such a hierarchy would make it possible to establish a rigorous scientific (...) theory of consciousness. The causal relationships implicit in definitions of access consciousness and phe- nomenal consciousness are made explicit, and the corresponding causal relationships at the more detailed levels of perception, memory, and skill learning described. Extension of these causal relationships to physiological and neural levels is discussed. The general capability of a range of current consciousness models to support a modular hierarchy which could generate these causal relationships is reviewed, and the specific capabilities of two models with good general capabilities are compared in some detail.

In a series of closely connected papers, Rosenthal has defended what has come to be known as “the higher-order thought theory of state-consciousness.” According to this theory, a mental state which one instantiates is conscious if and only if one is conscious of being in it in some relevant way, and one’s being conscious of being in the state which is conscious consists in one’s having a contemporaneous thought to the effect that one is in that state. (...) The main aim of this paper is to disarm a Searle-style objection to Rosenthal’s account of state-consciousness, one that takes mentality, in particular intentionality, to presuppose state-consciousness. It is argued that the Searlean attempt to convict Rosenthal’s hypothesis of circularity fails, because the postulation of what Searle called “subjective ontology,” as well as the requirement that there be an uncancelable connection between mode of representation and state-consciousness, is unreasonable. While defending Rosenthal against Searle, this paper also aims to develop a fresh objection to the higher-order thought conception of state-consciousness. (shrink)

In Thinking About Consciousness , David Papineau [2002] presents a criticism of so-called 'actualist HOT theories of consciousness'. The HOT theory, held most notably by David Rosenthal, claims that the best explanation for what makes a mental state conscious is that it is the object of an actual higher-order thought directed at the mental state. Papineau contends that actualist HOT theory faces an awkward problem in relation to higher-order memory judgements; for example, that the theory (...) cannot explain how one could later recall an earlier experience that was not introspected. He argues that, on the HOT theory, we are even left with the absurd conclusion that the consciousness of, say, an earlier visual experience might even depend on the later act of memory. I show that Papineau's criticism of actualist HOT theory not only fails, but also that it seriously mischaracterizes and underestimates the theory. In particular, Papineau badly conflates the crucial difference between an introspective state (i.e., where a conscious HOT is directed at a mental state) and an outer-directed first-order conscious state (i.e., a case where one has a nonconscious HOT).

I show that Nietzsche's puzzling and seemingly inconsistent claims about consciousness constitute a coherent and philosophically fruitful theory. Drawing on some ideas from Schopenhauer and F.A. Lange, Nietzsche argues that conscious mental states are mental states with conceptually articulated content, whereas unconscious mental states are mental states with non-conceptually articulated content. Nietzsche's views on concepts imply that conceptually articulated mental states will be superficial and in some cases distorting analogues of non-conceptually articulated mental states. Thus, the claim that (...) conscious states have a conceptual articulation renders comprehensible Nietzsche's claim that consciousness is "superficial" and "falsifying.". (shrink)

This review summarises why it is difficult for Darwinian evolutionary theory to explain the existence and function of consciousness. It then evaluates whether Humphrey's book Soul Dust overcomes these problems. According to Humphrey, consciousness is an illusion constructed by the brain to enhance reproductive fitness by motivating creatures that have it to stay alive. Although the review entirely accepts that consciousness gives a first-person meaning to existence, it concludes that Humphrey does not give a convincing account (...) of how this can arise from random variations in the genome. Nor does he demonstrate how first-person experiences might enter into or be reducable to third-person functioning. The review concludes that Humphrey's case is unconvincing, and goes on to suggest that an entirely different, non-reductive approach may be required to understand consciousness. (shrink)

The relationship between quantum collapse and consciousness is reconsidered under the assumption that quantum collapse is an objective dynamical process. We argue that the conscious observer can have a distinct role from the physical measuring device during the process of quantum collapse owing to the intrinsic nature of consciousness; the conscious observer can know whether he is in a definite state or a quantum superposition of definite states, while the physical measuring device cannot “know”. As a result, the (...) consciousness observer can distinguish the definite states and their quantum superposition, while the physical measuring device without consciousness cannot do. This provides a possible quantum physical method to distinguish man and machine. The new result also implies that consciousness has causal efficacies in the physical world when considering the existence of quantum collapse. Accordingly consciousness is not reducible or emergent, but a new fundamental property of matter. This may establish a quantum basis for panpsychism, and make it be a promising solution to the hard problem of consciousness. Furthermore, it is suggested that a unified theory of matter and consciousness includes two parts: one is the psychophysical principle or corresponding principle between conscious content and matter state, and the other is the complete quantum evolution of matter state, which includes the definite nonlinear evolution element introduced by consciousness and relating to conscious content. Lastly, some experimental schemes are presented to test the proposed quantum theory of consciousness. (shrink)

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

Among our conscious states are conscious thoughts. The question at the center of the recent growing literature on cognitive phenomenology is this: In consciously thinking P, is there thereby any phenomenology—is there something it’s like? One way of clarifying the question is to say that it concerns whether there is any proprietary phenomenology associated with conscious thought. Is there any phenomenology due to thinking, as opposed to phenomenology that is due to some co-occurring sensation or mental image? In this paper (...) we will present two arguments that a “yes” answer to this question of cognitive phenomenology can be obtained via appeal to the HOT theory of consciousness, especially the version articulated and defended by David Rosenthal.

This paper develops an adverbial theory of consciousness. Adverbialism is described and endorsed and defended from its near rival, an identity thesis in which conscious mental states are those that the mental subject self-knows immediately that he or she is "in". The paper develops an account of globally supported self-ascription to embed this neo-Brentanian view of experiencing consciously within a more general account of the relation between consciousness and self-knowledge. Following O'Shaughnessy, person level consciousness is explained (...) as a feature of the bundle of mental capacities characteristic of persons: person level consciousness involves a capacity holism. Drawing on Kant, it is argued that if a person is in a mental state intentionally directed to an object then such a subject can "self token" such knowledge. The content of that self-knoweldge supervenes on the possession of a global set of capacities, and this capacity for self-ascription depends on the fact that our experience has a perspectival character with, as it were, nothing at the vanishing point of this perspective. The fact that one can attach the cogito to any one of one's representation shows a truth about the unity of the conscious life of a person that cannot be stated and this capacity is distinguished from self-conscious thinking about oneself. This approach is contrasted to Shoemaker's functionalist treatment of the self-tokening of conscious states and of "self-blindness". It is argued that to be fully consistent, Shoemaker has to abandon the claim that introspectionism is guilty of a self-scanning model or rational control as he seems committed to that model too.

Michael Tye has recently argued that the phenomenal character of conscious experiences is "one and the same as" (1) Poised (2) Abstract (3) Non-conceptual (4) Intentional Content (PANIC). Tye argues extensively that PANIC Theory accounts for differences in phenomenal character in representational terms. But another task of a theory of phenomenal consciousness is to account for the difference between those mental states that have phenomenal character at all and those that do not. By going through each of (...) the four qualifiers of PANIC, we argue that PANIC Theory fails to account for this difference in genuinely representational terms. We suggest, furthermore, that the reasons it fails are likely to be endemic to all representational theories of phenomenal consciousness. (shrink)

[Final version in Philosophical Papers, 2000] Much has been made over the past few decades of two related problems in aesthetics. First, the "feeling fiction problem," as I will call it, asks: is it rational to be moved by what happens to fictional characters? How can we care about what happens to people who we know are not real?[i] Second, the so-called "paradox of tragedy" is embodied in the question: Why or how is it that we take pleasure in artworks (...) (e.g. tragedies) which are clearly designed to cause in us such feelings as sadness and fear?[ii] Various solutions to these puzzles have been proposed, but my primary aim is neither to offer a novel solution nor to summarize and critique most of the alternatives.[iii] My focus instead will be on the issue of consciousness and, more specifically, to view these problems from the point of the view of the so-called "higher-order thought theory of consciousness" (the HOT theory). Although some work on these puzzles have raised important questions about the nature of consciousness and "aesthetic experience," no attempt has yet been made to examine them in light of a specific theory.

From Descartes to Hume, philosophers in the seventeenth and eighteenth centuries developed a dialectic of radically conflicting claims about the nature of the self. In the Paralogisms of The Critique of Pure Reason, Kant comes to terms with this dialectic and with the character of the experiencing self. In this study, Powell seeks to elucidate these difficult texts, showing that the structure of the Paralogisms provides an essential key to understanding both Kant's critique of "rational psychology" and his theory (...) of self-consciousness. As Kant realized, the ways in which we must represent ourselves to ourselves have import not only for epistemology, but for our view of persons and of our own immortality, as well as for moral philosophy. His theory of self-consciousness is also shown to have implications for contemporary discussions of the problem of other minds, functionalism, and the problem of indexical self-reference. (shrink)

An innovative theory of consciousness, drawing on the phenomenology of Edmund Husserl and supported by brain-imaging, presented in the form of a hardboiled ...

Theories of what it is for a mental state to be conscious must answer two questions. We must say how we're conscious of our conscious mental states. And we must explain why we seem to be conscious of them in a way that's immediate. Thomas Natsoulas (1993) distinguishes three strategies for explaining what it is for mental states to be conscious. I show that the differences among those strategies are due to the divergent answers they give to the foregoing questions. (...) Natsoulas finds most promising the strategy that amounts to the higher-order-thought hypothesis that I've defended elsewhere. But he raises a difficulty for it, which he thinks probably can be met only by modifying that strategy. I argue that this is unnecessary. The difficulty is a special case of a general question, the answer to which is independent of any issues about consciousness. So it's no part of a theory of consciousness to address the problem, much less solve it. Moreover, the difficulty seems to have intuitive force only given the picture that underlies the other two explanatory strategies, which both Natsoulas and I reject. (shrink)

The present article distinguishes three kinds of accounts of direct (reflective) awareness (i.e. awareness of one's mental occurrences causally unmediated by any other mental occurrence): mental-eye theory, self-intimational theory and appendage theory. These aim to explain the same phenomenon, though each proposes that direct (reflective) awareness occurs in a fundamentally different way. Also, I address a crucial problem that appendage theory must solve: how does a direct (reflective) awareness succeed in being awareness specifically of the particular (...) mental-occurrence instance that is its object? Appendage theory is singled out for this attention because psychologists, as they embark on their renewed study of consciousness, are most likely to be attracted by appendage theory for their explanation of direct (reflective) awareness.

Integrative social contracts theory (ISCT) uses empirical methods to develop guidelines for international business ethics. This article criticizes ISCT in terms of the way people actually think about contracts and agreements around the globe. Differences in orientations to communications context, moral reasoning, and institutional and structural conditions make the identification of authentic norms, hypernorms, and relevant communities problematic. The difficulties of the empirical methods suggest recourse to more traditional theoretical approaches for the identification of hypernorms as well (...) as a stronger test for the compatibility of authentic norms with hypernorms.

This article summarizes a variety of current as well as previous research in support of a new theory of consciousness. Evidence has been steadily accumulating that information about a stimulus complex is distributed to many neuronal populations dispersed throughout the brain and is represented by the departure from randomness of the temporal pattern of neural discharges within these large ensembles. Zero phase lag synchronization occurs between discharges of neurons in different brain regions and is enhanced by presentation of (...) stimuli. This evidence further suggests that spatiotemporal patterns of coherence, which have been identified by spatial principal component analysis, may encode a multidimensional representation of a present or past event. How such distributed information is integrated into a holistic percept constitutes the binding problem. How a percept defined by a spatial distribution of nonrandomness can be subjectively experienced constitutes the problem of consciousness. Explanations based on a discrete connectionistic network cannot be reconciled with the relevant facts. Evidence is presented herein of invariant features of brain electrical activity found to change reversibly with loss and return of consciousness in a study of 176 patients anesthetized during surgical procedures. A review of relevant research areas, as well as the anesthesia data, leads to a postulation that consciousness is a property of quantumlike processes, within a brain field resonating within a core of structures, which may be the neural substrate of consciousness. This core includes regions of the prefrontal cortex, the frontal cortex, the pre- and paracentral cortex, thalamus, limbic system, and basal ganglia. (shrink)

Leibniz viewed the principle of continuity, the principle that all natural changes are produced by degrees, as a useful heuristic for evaluating the truth of a theory. Since the Cartesian laws of motion entailed discontinuities in the natural order, Leibniz could safely reject it as a false theory. The principle of continuity has similar implications for analyses of Leibniz's theory of consciousness. I briefly survey the three main interpretations of Leibniz's theory of consciousness and (...) argue that the standard account entails a discontinuity that Leibniz could not allow. I argue that the principle of continuity and the textual data favor an interpretation according to which a conscious mental state just is a perception that is distinct to a sufficient degree.

One of the promising approaches to the problem of consciousness has been the Higher-Order Monitoring Theory of Consciousness. According to the Higher-Order Monitoring Theory, a mental state M of a subject S is conscious iff S has another mental state, M*, such that M* is an appropriate representation of M. Recently, several philosophers have developed a Higher-Order Monitoring theory with a twist. The twist is that M and M* are construed as entertaining some kind of (...) constitutive relation, rather than being logically independent of each other. We may call this the Same-Order Monitoring Theory of Consciousness. In this paper, I discuss the nature of the Same-Order Monitoring Theory and argue for its superiority over the more traditional Higher-Order Monitoring Theory. (shrink)

In the physical sciences a rigorous theory is a hierarchy of descriptions in which causal relationships between many general types of entity at a phenomenological level can be derived from causal relationships between smaller numbers of simpler entities at more detailed levels. The hierarchy of descriptions resembles the modular hierarchy created in electronic systems in order to be able to modify a complex functionality without excessive side effects. Such a hierarchy would make it possible to establish a rigorous scientific (...) theory of consciousness. The causal relationships implicit in definitions of access consciousness and phe- nomenal consciousness are made explicit, and the corresponding causal relationships at the more detailed levels of perception, memory, and skill learning described. Extension of these causal relationships to physiological and neural levels is discussed. The general capability of a range of current consciousness models to support a modular hierarchy which could generate these causal relationships is reviewed, and the specific capabilities of two models with good general capabilities are compared in some detail.

Gadamer's philosophical hermeneutics belongs to the phenomenological tradition. What is striking then is that one of the central themes in phenomenology, the nature of time consciousness, receives no sustained treatment in Gadamer's writings. It's fair to say that Gadamer is the only major figure in phenomenology not to address the issue of time at length. In this paper I argue that Gadamer does have an account of time consciousness and it can be found most fully (...) articulated in his account of the aesthetic experience connected to festivals. Festivals, as models of epochal experiences, are the primordial experiences of time upon which other forms of time consciousness (time as used and filled and scientific time) are constituted. Significantly, then, the reproduction of the meaning of tradition plays a role in the heart of Gadamer's theory of time and therefore his theory of experience. (shrink)

The human ability to represent, conceptualize, and reason about mind and behavior is one of the greatest achievements of human evolution and is made possible by a “folk theory of mind” — a sophisticated conceptual framework that relates different mental states to each other and connects them to behavior. This chapter examines the nature and elements of this framework and its central functions for social cognition. As a conceptual framework, the folk theory of mind operates prior to any (...) particular conscious or unconscious cognition and provides the “framing” or interpretation of that cognition. Central to this framing is the concept of intentionality, which distinguishes intentional action (caused by the agent’s intention and decision) from unintentional behavior (caused by internal or external events without the intervention of the agent’s decision). A second important distinction separates publicly observable from publicly unobservable (i.e., mental) events. Together, the two distinctions define the kinds of events in social interaction that people attend to, wonder about, and try to explain. A special focus of this chapter is the powerful tool of behavior explanation, which relies on the folk theory of mind but is also intimately tied to social demands and to the perceiver’s social goals. A full understanding of social cognition must consider the folk theory of mind as the conceptual underpinning of all (conscious and unconscious) perception and thinking about the social world.

This is a Precis of my book _Subjective Consciousness: A Self-Representational Theory_. It does the usual.

This paper offers a novel way of reconstructing conceptual change in empirical theories. Changes occur in terms of the structure of the dimensions—that is to say, the conceptual spaces—underlying the conceptual framework within which a given theory is formulated. Five types of changes are identified: (1) addition or deletion of special laws, (2) change in scale or metric, (3) change in the importance of dimensions, (4) change in the separability of dimensions, and (5) addition or deletion of dimensions. (...) Given this classification, the conceptual development of empirical theories becomes more gradual and rationalizable. Only the most extreme type—replacement of dimensions—comes close to a revolution. The five types are exemplified and applied in a case study on the development within physics from the original Newtonian mechanics to special relativity theory. (shrink)

While previous studies of Dewey's work have taken either a historical or topical focus, Shook offers an innovative, organic approach to understanding Dewey and eloquently shows that Dewey's instrumentalism grew seamlessly out of his idealism. He argues that most current scholarship operates under a mistaken impression of Dewey's early philosophical positions.

I argue that a dual-aspect theory of consciousness, associated with a particular class of quantum states, can provide a consistent account of consciousness. I illustrate this with the use of coherent states as this class. The proposal meets Chalmers 'requirements of allowing a structural correspondence between consciousness and its physical correlate. It provides a means for consciousness to have an effect on the world (it is not an epiphenomenon, and can thus be selected by evolution) (...) in a way that supplements and completes conventional physics, rather than interfering with it. I draw on the work of Hameroff and Penrose to explain the consistency of this proposal with decoherence, while adding details to this work. The proposal is open to extensive further research at both theoretical and experimental levels. (shrink)

The same-order representation theory of consciousness holds that conscious mental states represent both the world and themselves. This complex representational structure is posited in part to avoid a powerful objection to the more traditional higher-order representation theory of consciousness. The objection contends that the higher-order theory fails to account for the intimate relationship that holds between conscious states and our awareness of them--the theory 'divides the phenomenal labor' in an illicit fashion. This 'failure of (...) intimacy' is exposed by the possibility of misrepresentation by higher-order states. In this paper, I argue that despite appearances, the same-order theory fails to avoid the objection, and thus also has troubles with intimacy. (shrink)

This article tackles problems concerning the reduction of phenomenal consciousness to brain processes that arise in consideration of specifically epistemological properties that have been attributed to conscious experiences. In particular, various defenders of dualism and epiphenomenalism have argued for their positions by assuming special epistemic access to phenomenal consciousness. Many physicalists have reacted to such arguments by denying the epistemological premises. My aim in this paper is to take a different approach in opposing dualism and argue that when (...) we correctly examine both the phenomenology and neural correlates of phenomenal consciousness we will see that granting the epistemological premises of special access are the best hope for a scientific study of consciousness. I argue that essential features of consciousness involve both their knowability by the subject of experience as well as their egocentricity, that is, their knowability by the subject as belonging to the subject. I articulate a neuroscientifically informed theory of phenomenal consciousness. (shrink)

A new constructivist approach to modeling in economics and theory of consciousness is proposed. The state of elementary object is defined as a set of its measurable consumer properties. A proprietor's refusal or consent for the offered transaction is considered as a result of elementary economic measurement. Elementary (indivisible) technology, in which the object's consumer values are variable, in this case can be formalized as a generalized economic measurement. The algebra of such measurements has been constructed. It has (...) been shown that in the general case the quantummechanical formalism of the theory of selective measurements is required for description of such conditions. The economic analogs of the elementary slit experiments in physics have been created. The proposed approach can be also used for consciousness modeling. (shrink)

Mandik (2010) defends a motor theory of control consciousness according to which nonsensory states, like motor commands, directly contribute to the awareness we have of ourselves as being in control of our actions. Along the way, he argues that his theory is to be preferred over Prinz’s (2007) sensory imagery theory, which denies that nonsensory states play any direct role in the generation of control consciousness. I argue that Mandik’s criticisms of Prinz’s theory fall (...) short, but that nonetheless there are reasons to favor a motor theory of control consciousness over a sensory imagery theory. (shrink)

In this paper, I will present an argument against Husserl’s analysis of picture consciousness. Husserl’s analysis of picture consciousness (as it can be found primarily in the recently translated volume Husserliana 23) moves from a theory of depiction in general to a theory of perceptual imagination. Though, I think that Husserl’s thesis that picture consciousness is different from depictive and linguistic consciousness is legitimate, and that Husserl’s phenomenology avoids the errors of linguistic theories, such (...) as Goodman’s, I submit that his overall theory is unacceptable, especially when it is applied to works of art. Regarding art, the main problem of Husserl’s theory is the assumption that pictures are constituted primarily as a conflict between perception/physical picture thing and imagination/picture object. Against this mentalist claim, I maintain, from a hermeneutic point of view, that pictures are the result of perceptual formations [Bildungen]. I then claim that Husserl’s theory fails, since it does not take into account what I call “plastic perception” [Bildliches Sehen], which plays a prominent role not only within the German tradition of art education but also within German art itself. In this connection, “plastic thinking” [Bildliches Denken] was prominent especially in Klee, in Kandinsky, and in Beuys, as well as in the overall doctrine of the Bauhaus. Ultimately, I argue that Husserl’s notion of picture consciousness and general perceptive imaginary consciousness must be replaced with a more dynamic model of the perception of pictures and art work that takes into account (a) the constructive and plastic moment, (b) the social dimension and (c) the genetic dimension of what it means to see something in something (Wollheim).

The emulation theory of representation articulated in the target article is further explained and explored in this response to commentaries. Major topics include: the irrelevance of equilibrium-point and related models of motor control to the theory; clarification of the particular sense of “representation” which the emulation theory of representation is an account of; the relation between the emulation framework and Kalman filtering; and addressing the empirical data considered to be in conflict with the emulation theory. (...) In addition, I discuss the further empirical support for the emulation theory provided by some commentators, as well as a number of suggested theoretical applications. (shrink)

It would be hard to deny that the experience of emotion is one of the most significant aspects of consciousness. While it is possible to imagine a being who enjoyed some forms of consciousness while lacking any awareness of its emotional states, such a being’s conscious life would be radically different from human consciousness. Yet, I believe that in fact we are surrounded by such beings and, most of the time, we ourselves are such. This is not (...) to say that such beings lack emotions, or that they lack consciousness, or even that they lack a specific sort of emotional consciousness. But to be conscious of one’s own emotional state is much more complex than any of that, and much more rare. The framework within which I want to explore emotional consciousness is that of the representational theory of consciousness (RTC). One of the most exciting and fruitful advances in recent philosophical research in consciousness, there is now a plethora of distinct versions of RTC (see for example Carruthers 2000, Dretske 1995, Gennaro 1999, Lycan 1996, Rosenthal 1985, 1993a, 1993b, Tye 1995). Although I think the ultimate mystery of how or why the brain generates conscious experience remains unresolved by RTC, the theory nonetheless offers many insights into the nature of consciousness, and provides a theoretical viewpoint which addresses many of the philosophical problems of consciousness. In this paper, I want to extend the RTC so as to provide a theory of emotional consciousness and emotional introspection. The RTC postulates that if a cognitive system is conscious then it represents. More, consciousness is a kind of representation. Obviously, not every system that represents is conscious and not every representation generated by a conscious system is a conscious representation. Unfortunately, it is not yet very well understood what are the exact criteria for a representation’s being a conscious representation. Very abstractly, RTC posits that representations which play a certain ‘appropriate’ role within a cognitive system of ‘sufficient’ complexity are conscious representations.. (shrink)

Consciousness and the mind are prescientific concepts that begin with Greek theorizing. They suppose human rationality and reasoning placed in the human head by God, who structured the universe he created with the same kind of underlying characteristics. Descartes’ development of the model included scientific objectivity by placing the mind outside the physical universe. In its failure under evidential scrutiny and without physical explanation, this model is destined for terminal decline. Instead, a genuine biological and physical function for the (...) brain phenomenon can be developed. This is the theory of brain-sign. It accepts the causality of the brain as its physical characteristics, already under scientific scrutiny. What is needed is a new neurophysiological language that specifies the relation of the structure and operation of the brain to organismic action in the world. Still what is lacking is an account of how neurophysiologies in different organisms communicate on unpredictable dynamic tasks. It is this evolved capacity that has emerged as brain-sign. Thus rather than mentality being an inner epistemological parallel world suddenly appearing in the head, brain-sign, as the neural sign of the causal status of the brain capable of being held adequately in common, facilitates the communicative medium of otherwise isolated organisms. The biogenesis of the phenomenon thus emerges directly from the account of the physical brain, and functions as a monistic feature of organisms in the physical world. This new paradigm offers disciplinary compatibility, and genuine development in behavioral and brain sciences. (shrink)

In this article, we argue that a critical examination of epistemological and anthropological presuppositions might lead to a more fruitful use of theory in clinical-ethical practice. We differentiate between two views of conceptualizing ethics, referring to Charles Taylors' two epistemological models: ‘monological’ versus ‘dialogical consciousness’. We show that the conception of ethics in the model of ‘dialogical consciousness’ is radically different from the classical understanding of ethics in the model of ‘monological consciousness’. To reach accountable moral (...) judgments, ethics cannot be conceptualized as an individual enterprise, but has to be seen as a practical endeavor embedded in social interactions within which moral understandings are being negotiated. This view has specific implications for the nature and the role of ethical theory. Theory is not created in the individual mind of the ethicist; the use of theory is part of a joint learning process and embedded in a cultural context and social history. Theory is based upon practice, and serves practical purposes. Thus, clinical ethics support is both practical and theoretical. (shrink)

In scientific explanations, the explanans theory is sometimes incommensurable with the explanandum empirical data. How is this possible, especially when the explanation is deductive in nature? This paper attempts to solve the puzzle without relying on any particular theory of reference. For us, it is rather obvious that the geometric idea of projection plays a key role in Keplers explanation of Tycho Brahes empirical data. We discover that a similar mechanism operates in theoretic explanations in general. (...) In short, all theoretic explanations are projective explanations. If so, there should be no logical reason why explanans theories cannot be incommensurable with explanandum data. For illustration, we analyse Einsteins explanation of the results of the Michelson–Morley experiment in some detail. (shrink)

Dienes & Perner offer us a theory of explicit and implicit knowledge that promises to systematise a large and diverse body of research in cognitive psychology. Their advertised strategy is to unpack this distinction in terms of explicit and implicit representation. But when one digs deeper one finds the “Higher-Order Thought” theory of consciousness doing much of the work. This reduces both the plausibility and usefulness of their account. We think their strategy is broadly correct, but that (...) consensus on the explicit/implicit knowledge distinction is still a fair way off. (shrink)

Reconstructing the evolution of cognition requires maximal extraction of information from very sparse data. The role that archaeology plays in this process is important, but strong empirical tests of plausible hypotheses are absolutely critical. Quantitative measures of symmetry must be devised, a much deeper understanding of nonhuman primate spatial cognition is needed, and a better understanding of brain/behavior relationships across species is necessary to properly ground these hypotheses.

Philosophers frequently treat certainty as some sort of absolute, while ordinary men typically do not. According to the Theory of Important Criteria, on which the present paper is based, this difference is not to be explained in terms of ambiguity or vagueness in the word ?certain?, but rather in terms of disagreement between ordinary men and philosophers as to the importance of one of the criteria of the ordinary sense of ?certain?. I argue that there is reason to think (...) that certainty is some sort of absolute, and thus that no empirical statement is certain. And in any case, the problem of empirical certainty is not a pseudo?problem, as metaphilosophers like Wittgenstein and Wisdom have thought. (shrink)

In the past few decades, scholars have offered positive, normative, and most recently, interpretive theories of contract law. These theories have proceeded primarily (indeed, necessarily) from deontological and consequentialist premises.

Alces confronts the leading interpretive theories of contract and demonstrates their interpretive doctrinal failures. Professor Alces presents the leading canonical cases that inform the extant theories of Contract law in both their historical and transactional (...) contexts and, argues that moral psychology provides a better explanation for the contract doctrine than do alternative comprehensive interpretive approaches.

b>. One major problem many hypotheses regarding the neural correlate of consciousness (NCC) face is what we might call “the why question”: _why _would this particular neural feature, rather than another, correlate with consciousness? The purpose of the present paper is to develop an NCC hypothesis that answers this question. The proposed hypothesis is inspired by the Cross-Order Integration (COI) theory of consciousness, according to which consciousness arises from the functional integration of a first-order representation (...) of an external stimulus and a second-order representation of that first-order representation. The proposal comes in two steps. The first step concerns the “general shape” of the NCC and can be directly derived from COI theory. The second step is a concrete hypothesis that can be arrived at by combining the general shape with empirical considerations. (shrink)

There are currently two main philosophical theories of perception - Direct Realism and the Representative Theory. The former is supported by most contemporary philosophers, whereas the latter forms the groundwork for most scientific theories in this area. The paper describes a recent experiment involving retinal and cortical rivalry that provides strong empirical evidence that the Direct Realist theory is incorrect. There are of course a large number of related experiments on visual perception that would tend to lead (...) us to the same conclusion, but the experiment described in this paper does so in a singularly direct and straightforward manner. Often the most telling experiments are the simplest. (shrink)

David Rosenthal's higher-order thought (HOT) theory is one of the most widely argued for of the higher-order accounts of consciousness. I argue that Rosenthal vacillates between two models of the HOT theory. First, I argue that these models employ different concepts of 'state consciousness'; the two concepts each refer to mental state tokens, but in virtue of different properties. In one model, the concept of 'state consciousness' is more consistent with how the term is typically (...) used, both by philosophers and scientists, and in commonsense usage. This model, however, also has its problems. In the second part of the paper, I develop a modified version of Rosenthal's transitivity principle, thereby avoiding some complications that stem from the original transitivity principle. I suggest that Rosenthal occasionally employs this modified model himself, and that the inconsistency identified in the first section of this paper might really reflect Rosenthal's vacillation between these two versions of the transitivity principle. I offer one explanation for how this equivocation may have occurred. These two versions would result if articulations of the transitivity principle employed the term 'mental state' inconsistently, to refer on some occasions merely to mental state types, and on others, to tokened mental states. I conclude by arguing, contrary to Rosenthal and others, that the theory is not incompatible with view that conscious states are uniquely casual efficacious. (shrink)

From the assumption that the presence of consciousness is detectable, in the first instance, only from behavioral indicators, I offer a proof to the effect that, with respect to any theory T that states that some particular state or process is the neural correlate of consciousness, there are always rival neural correlates that, from T’s perspective, can never be empirically ruled out. That's because, with respect to these states, the means of detecting consciousness is disrupted along (...) with the empirical test. Possible responses are discussed. (shrink)

The topic of the article is how moral development theory can enlighten the understanding of ethical behaviour in business. It discusses previous research on the subject, and reports an empirical study of academics (engineers and business economists with a master degree) working in the private sector in Norway.Moral development theory is based on a long research tradition, and many researchers within business ethics have assumed the importance of moral reasoning in business environments. However, the truth of these (...) assumptions has not been confirmed by previous empirical research. (shrink)

In recent decades, with advances in the behavioral, cognitive, and neurosciences, the idea that patterns of human behavior may ultimately be due to factors beyond our conscious control has increasingly gained traction and renewed interest in the age-old problem of free will. In this book I examine both the traditional philosophical problems long associated with the question of free will, such as the relationship between determinism and free will, as well as recent experimental and theoretical work directly related to (...) class='Hi'>consciousness and human agency. I argue that our best scientific theories indeed have the consequence that factors beyond our control produce all of the actions we perform and that because of this we do not possess the kind of free will required for genuine or ultimate responsibility. I further argue that the strong and pervasive belief in free will, which I consider an illusion, can be accounted for through a careful analysis of our phenomenology and a proper theoretical understanding of consciousness. Indeed, the primary goal of this book is to argue that our subjective feeling of freedom, as reflected in the first-person phenomenology of agentive experience, is an illusion created by certain aspects of our consciousness. So after working to establish that free will is an illusion in the early chapters, I then proceed to give a novel account of just how that illusion is created in the later chapters. I present my illusionist account using one leading theory of consciousness—the higher-order thought (or HOT) theory of consciousness. I maintain that by combining the theoretical framework of the HOT theory with empirical findings in the behavioral, cognitive, and neurosciences, we can come to see that the illusion of free will is created by the particular way our higher-order thoughts make us conscious of our mental states and how our sense of self is constructed within consciousness.

Modern consciousness studies are in a healthy state, with many progressive empirical programmes in cognitive science, neuroscience and related sciences, using relatively conventional third-person research methods. However not all the problems of consciousness can be resolved in this way. These problems may be grouped into problems that require empirical advance, those that require theoretical advance, and those that require a re-examination of some of our pre-theoretical assumptions. I give examples of these, and focus on two problems—what (...) consciousness is, and what consciousness does—that require all three. In this, careful attention to conscious phenomenology and finding an appropriate way to relate first-person evidence to third-person evidence appears to be central to progress. But we may also need to re-examine what we take to be “natural facts” about the world, and how we can know them. The same appears to be true for a trans-cultural understanding of consciousness that combines classical Indian phenomenological methods with the third-person methods of Western science. (shrink)

It is argued that we need a richer version of Bayesian decision theory, admitting both subjective and objective probabilities and providing rational criteria for choice of our prior probabilities. We also need a theory of tentative acceptance of empirical hypotheses. There is a discussion of subjective and of objective probabilities and of the relationship between them, as well as a discussion of the criteria used in choosing our prior probabilities, such as the principles of indifference and of (...) maximum entropy, and the simplicity ranking of alternative hypotheses.

In our dealings with animals at least most of us see them as conscious beings. On the other hand the employment of human categories to animals seems to be problematic. Reflecting on the details of human beliefs, for example, casts serious doubt on whether the cat is able to believe anything at all. These theses try to reflect on methodological issues when investigating animal minds. Developing a theory of animal mentality seems to be a <span class='Hi'>test</span> case of the (...) interdisciplinary research programme in cognitive science. From the philosopher`s perspective the most pressing problem is how to talk about animal minds. Can we just employ the vocabulary of human psychology? If not, exploring animal minds contains the non-trivial task of introducing a terminology that allows to see the distinctness of animal minds and to see its connection to the human case. The treatment of some topic in cognitive science has to reach a reflective equilibrium between our intuitions, a phenomenological approach, philosophical conceptual analysis, various empirical approaches and model building. Reflective equilibrium means in this context that we have to reach a coherent model which incorporates as much of our intuitions concerning animal consciousness and integrates at the same time the findings of the different co-operating sciences. There can be various trade-offs in case of conflict between, say, philosophical definitions of mental terms as to be applied to animals, neurophysiology, our reflected intuitions and ethological model building based on a computational theory of animal minds. The paper gives an example of reflective equilibrium in discussing the case for awareness in vertebrates. It considers the role of evolutionary reasoning. The main focus lays on two examples of comparing our human notions (chosen here are “having concepts” and “belief”) with corresponding abilities in animals, and how an appropriate conceptual apparatus dealing with the abilities of animals could be introduced.

INTRODUCTION This book is devoted to the formulation and the development of a paradigmatic-phenomenological theory of cognition. ...

The purpose of this work is to analyse the cognitive process of the domain theories in terms of the measurement theory to develop a computational machine learning approach for implementing it. As a result, the relational data mining approach, the authors proposed in the preceding books, was improved. We present the approach as an implementation of the cognitive process as the measurement theory perceived. We analyse the cognitive process in the first part of the paper and present the (...) theory and method of the logically most powerful empirical theory discovery in the second. The theory is based on the notion of law-like rules, which conform to all the properties of laws of nature, namely generality, simplicity, maximum refutability and minimum number of parameters. This notion is defined for deterministic and probabilistic cases. Based on the method, the discovery system is developed. The system was successfully applied to many practical tasks. (shrink)

Within the domain of philosophy, it is not unusual to hear the claim that most questions about the nature of consciousness are essentially and absolutely beyond the scope of science, no matter how science may develop in the twenty-first century. Some things, it is pointed out, we shall never _ever_ understand, and consciousness is one of them (Vendler 1994, Swinburne 1994, McGinn 1989, Nagel 1994, Warner 1994). One line of reasoning assumes that consciousness is the manifestation of (...) a distinctly nonphysical thing, and hence has no physical properties that might be explored by techniques suitable to physical things. Dualism, as this view is known, is still to be found among those within the tradition of Kant and Hegel, as well as among some with religious convictions. Surprisingly, however, strenuous foot-dragging is evident even among philosophers of a materialist conviction. Indeed, one might say that it is the philosophical fashion of the 90's to pronounce consciousness unexplainable, and to find the explanatory aspirations of neurobiology to be faintly comic if not rather pitiful. The very word, "reductionism" has come to be used more or less synonymously with "benighted-scientism-run-amok", where scientistm apparently means "applying scientific techniques to domains where they are inapplicable." McGinn, perhaps the most unblushing of the naysayers, insists that we cannot expect even to make any headway on the problem. (p. 114) Ironically perhaps, here we are at a conference in honor of Dr. Herbert Jasper who was a great pioneer in moving neuroscience forward on this problem, and where results will be presented allegedly _showing_ additional progress on the problem. Because I am quite optimistic about future scientific progress on the nature of consciousness, my aim here, as a philosopher, is to address the most popular and influential of the skeptical arguments, and to explain why I find them unconvincing. Thus the overall form of the paper is negative, in the sense that I want to show why a set of naysaying arguments fail. (shrink)

Reading the philosophical literature on consciousness, one might get the idea that there is just one problem in consciousness studies, the hard problem. That would be a mistake. There are other problems; some are more tractable, but none are easy, and all interesting. The literature on the hard problem gives the impression that we have made little progress. Consciousness is just an excuse to work and re-work familiar positions on the mind-body problem. But progress is being made (...) elsewhere. Researchers are moving towards increasingly specific accounts of the neural basis of conscious experience. These efforts will leave some questions unanswered, but they are no less significant for that. (shrink)

This interdisciplinary work contains the most sustained attempt at developing and defending one of the few genuine theories of consciousness.

In many forms of severe acute brain injury there is an early phase when prognosis is uncertain, followed later by physiological recovery and the possibility of more certain predictions of future impairment. There may be a window of opportunity for withdrawal of life support early, but if decisions are delayed there is the risk that the patient will survive with severe impairment. In this paper I focus on the example of neonatal encephalopathy and the question of the timing of prognostic (...) tests and decisions to continue or to withdraw life-sustaining treatment. Should testing be performed early or later; and how should parents decide what to do given the conflicting values at stake? I apply decision theory to the problem, using sensitivity analysis to assess how different features of the tests or different values would affect a decision to perform early or late prognostic testing. I draw some general conclusions from this model for decisions about the timing of testing in neonatal encephalopathy. Finally I consider possible solutions to the problem posed by the window of opportunity. Decision theory highlights the costs of uncertainty. This may prompt further research into improving prognostic tests. But it may also prompt us to reconsider our current attitudes towards the palliative care of newborn infants predicted to be severely impaired. (shrink)

In this paper, I argue that the causal and description theories of natural kind term reference involve certain psychological elements. My main goal is to refine these theories with the help of empirical psychology of concepts, and to argue that the refinement process ultimately leads to the dissolution of boundaries between the two kinds of theories. However, neither the refined theories nor any other existing theories provide an adequate answer to the question of what makes natural kind terms rigid. (...) To provide an answer to this question I conclude my paper by introducing a framework of a unified theory of natural kind term reference that is built on the empirical psychology of concepts.

. Standard considerations of philosophy of science are reformulated in psychological terms and arguments, suggesting a fundamental change in life perspective: subjective experiences or introspective data are subject to motivational biases and therefore not admitted as objective empirical facts in science, However, we never experience objects or events of the external world, i.e., so called objective facts, but exclusively subjective percepts or mental events. They are merely assumed to, but may or may not be accurate or distorted mental representations (...) of objects or events of an external world. Accordingly, the latter are theoretical constructs, i.e., constructs of the fictitious but most successful predictive (implicit) theory, called external world, which seems to be constructed from regularities observed in mental events and serves as a reference fiction for, erroneously called empirical, tests of predictions of scientific theories.

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible (alas!), and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and (...) arguments developed earlier to defend a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

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)

It is suggested that the anatomical structures whichmediate consciousness evolved as decisiveembellishments to a (non-conscious) design strategypresent even in the simplest monocellular organisms.Consciousness is thus not the pinnacle of ahierarchy whose base is the primitive reflex, becausereflexes require a nervous system, which the monocelldoes not possess. By postulating that consciousness isintimately connected to self-paced probing of theenvironment, also prominent in prokaryotic behavior,one can make mammalian neuroanatomy amenable todramatically simple rationalization.

While "Consciousness Explained" has received an enormous amount of attention since its publication, there is still little agreement on what Dennett’s account of consciousness is. Most interpreters treat his view as an instance of one or another of the standard ontological positions (functionalism, behaviorism, eliminativism, instrumentalism). I believe a different metaphysical account underlies Dennett’s view, one that is important though ill-understood. In the paper I attempt to point in the direction of a proper characterization of that account through (...) the use of two illustrative examples. A ten-point story that applies to the examples is developed, and it is suggested that the story applies equally well to Dennett’s view of consciousness. (shrink)
