In this paper, it is argued that the late twentieth century conception of consciousness in analytic philosophy emerged from the idea of consciousness as givenness, via the behaviourist idea of “raw feels”. In the post-behaviourist period in philosophy, this resulted in the division of states of mind into essentially unconscious propositional attitudes plus the phenomenal residue of qualia: intrinsic, ineffable and inefficacious sensory states. It is striking how little in the important questions about consciousness depends on this conception, or on (...) this particular division of mental states. So accepting this division and its associated conceptions of intentionality and consciousness is not an obligatory starting point for the philosophy of mind. A historical investigation of how these ideas came to be seen as inevitable can also help us see how we might reasonably reject them. (shrink)

What would Gottfried Wilhelm Leibniz have said about today’s problem of consciousness? Some philosophers claim that Leibniz was one of the first to argue that there is an ‘explanatory gap’ between our knowledge of matter and our knowledge of consciousness, and that he thought this posed a problem for materialism (see for example Churchland 1995: 191-2; Kriegel 2015: 49; Seager 1991; Searle 1983: 267-8). This is supposed to be the point of the famous passage in the Monadology (1714), in which (...) Leibniz argues that perception is ‘inexplicable in terms of mechanical reasons’... (shrink)

This paper starts from the assumption that panpsychism is counterintuitive and metaphysically demanding. A number of philosophers, whilst not denying these negative aspects of the view, think that panpsychism has in its favour that it offers a good explanation of consciousness. In opposition to this, the paper argues that panpsychism cannot help us to explain consciousness, at least not the kind of consciousness we have pre-theoretical reason to believe in.

The mind-body problem in philosophy is typically understood as a discourse concerning the relation of mental states to physical states, and the experience of sensation. On this level it seems to transcend issues of race and racism, but Another Mind-Body Problem demonstrates that racial distinctions have been an integral part of the discourse since the Modern period in philosophy. Reading figures such as Descartes, Leibniz, and Kant in their historical contexts, John Harfouch uncovers discussions of mind and body that engaged (...) closely with philosophical and scientific notions of race in metaphysics and the philosophy of mind, in particular in understanding how the mind unites with the body at birth and is then passed on through sexual reproduction. Kant argued that a person’s exterior body and interior psyche are bound together, that non-White people lacked reason, and that this lack of reason was carried on through reproduction such that non-Whites were an example of a union of mind and body without full being. Charting the development of this phenomenon from sixteenth-century medical literature to modern-day race discourse, Harfouch argues for new understandings of Descartes’s mind-body problem, Fanon’s experience of being ‘not-yet human,’ and the place of racism in relation to one of philosophy’s most enduring and canonical problems. -/- “Harfouch has written an important book on the intersection of race and the Western construction of the mind-body problem … This book is a significant resource for theorists dealing with race and decolonization issues, but it is more significant for the critique of philosophy itself and the continued teaching of mind-body issues. Readers will need some knowledge of philosophy, but the volume is in general accessible. It should be required reading for scholars of philosophy. Harfouch establishes a logically strong argument and makes a unique contribution to the field.” — CHOICE. (shrink)

RESUMEN La psicopatologia contemporánea sufre de una brecha descriptiva respecto de la experiencia patológica, y la tradición de la psicopatologia contiene un capital descriptivo acumulado que debe ser explotado para la necesaria superación de este déficit. Se argumenta examinando el caso particular de la psicopatologia cognitiva de la esquizofrenia y del contenido de la experiencia del delirio de control, mostrando cómo la teoría de Henri Ey, así como la del automatismo mental del siglo xix en la cual tiene sus raíces, (...) contienen herramientas descriptivas importantes para establecer que la experiencia de un delirio de control es esencialmente diferente de la experiencia de una simple ilusión de control. ABSTRACT This article defends the general view that contemporary psychopathology suffers from a descriptive gap with respect to pathological experience and that the psycho-pathological tradition has accumulated a descriptive capital that should be used in the necessary effort to overcome this gap. This general thesis is argued for by examining the specific case of the cognitive psychopathology of schizophrenia and the experience of the delusion of control, showing how Henri Ey's theory and the 19th century theory of mental automatism in which the former is rooted contain important descriptive tools for establishing that the experience of a delusion of control is fundamentally different from that of a sheer illusion of control.

In this article we aim to see how far one can get in defending the identity thesis without challenging the inference from conceivability to possibility. Our defence consists of a dilemma for the modal argument. Either “pain” is rigid or it is not. If it is not rigid, then a key premise of the modal argument can be rejected. If it is rigid, the most plausible semantic account treats “pain” as a natural-kind term that refers to its causal or historical (...) origin, namely, C-fibre stimulation. It follows that any phenomenon that is not C-fibre stimulation is not pain, even if it is qualitatively similar to pain. This means there could be phenomena that feel like pain but are not pain since they are not C-fibre stimulation. These possible phenomena can be used to explain away the apparent conceivability of pain without C-fibre stimulation. On either horn of the dilemma, the identity theorist has ample resources to respond to Kripke's argument, even without wandering into the contentious territory of conceivability and possibility.

Um dos grandes desafios da era da informação consiste em filtrar informações claras, rigorosas e atualizadas sobre tópicos importantes. O mesmo vale para a filosofia. Como encontrar conteúdo filosófico confiável em meio a milhares de artigos publicados diariamente na internet? Para ir ainda mais longe, como encontrar uma introdução a algum tópico com uma lista de referências bibliográficas atualizadas e que seja organizada por um especialista da área? Já que você começou a ler este livro, é provável que tenha ouvido (...) falar em algum momento da Enciclopédia Stanford de Filosofia, disponível gratuitamente na internet desde 1995. A página da Stanford faz exatamente isso. Ela cobre inúmeros verbetes sobre quase tudo em filosofia, oferecendo informação confiável sobre temas como feminismo, filosofia na América Latina, zumbis, metafísica e milhares de outros tópicos. A sugestão típica aos profissionais da filosofia que têm interesse em começar a estudar algum tópico, mas não sabem sequer por onde começar, é procurar pelo verbete relevante da Stanford. Infelizmente, o grande empecilho da página para o nosso contexto é que todos os verbetes estão disponíveis apenas em inglês, algo que cria um obstáculo a inúmeros estudantes e interessados que não dominam a língua. Neste sentido, acreditamos que esta publicação preencha um hiato importante na filosofia brasileira. Embora a filosofia no Brasil tenha se profissionalizado e expandido ao longo dos anos, há ainda lacunas em diversas áreas, e os verbetes foram aqui selecionados cuidadosamente no intuito de preencher ao menos algumas dessas lacunas. Este livro apresenta quatro verbetes cruciais para a filosofia, aqui divididos em quatro capítulos: (1) condições necessárias e suficientes, (2) referência (3) causação e (4) consciência. (shrink)

What is the source of logical and mathematical truth? This book revitalizes conventionalism as an answer to this question. Conventionalism takes logical and mathematical truth to have their source in linguistic conventions. This was an extremely popular view in the early 20th century, but it was never worked out in detail and is now almost universally rejected in mainstream philosophical circles. Shadows of Syntax is the first book-length treatment and defense of a combined conventionalist theory of logic and mathematics. It (...) argues that our conventions, in the form of syntactic rules of language use, are perfectly suited to explain the truth, necessity, and a priority of logical and mathematical claims, as well as our logical and mathematical knowledge.

La discusión en filosofía de la mente del último siglo giró en torno a los dualismos y monismos ontológicos para explicar la consciencia y los conceptos mentales. Uno de los rasgos distintivos de la discusión fue la pregunta por la existencia de una brecha explicativa entre las categorías mentales y físicas, y el reto de explicar la relación causal entre estas. De ahí que el objetivo de este trabajo sea analizar los problemas que no permitieron el avance en la reflexión (...) filosófica sobre la ontología de la consciencia y los conceptos mentales. Para ello, primero, se introduce el problema difícil de la consciencia y las diversas acepciones sobre lo que significa ser consciente; segundo, se analiza críticamente algunas de las tendencias ontológicas dualistas y monistas más emblemáticas de la filosofía; tercero, se presentan varias de las inconsistencias de las teorías ontológicas tradicionales respecto a la comprensión de la consciencia y el lenguaje psicológico, y cuarto, se brindan argumentos a favor de la idea de que muchos de los problemas filosóficos sobre la consciencia y la relación entre la mente y el cuerpo son el resultado de un mal entendimiento de la naturaleza de los conceptos mentales. El artículo concluye que la negación de la experiencia consciente, el lenguaje mental y los dilemas categoriales de la tradición dualista cartesiana deben quedar en el pasado. (shrink)

This monograph introduces a meta-framework for conducting interdisciplinary research in the science of emotion, as well as a framework for a particular kind of theory of emotion. It can also be understood as a “cross-over” book that introduces neophytes to some of the current discourse and major challenges for an interdisciplinary approach to the science of emotion, especially from a philosophical perspective. It also engages experts from across the disciplines who are interested in conducting an interdisciplinary approach to research and (...) theorizing in the science of emotion, and introduces to them some of the contemporary debates in the philosophy of emotion. It does so by providing a taxonomy of theories of emotion which allows one to understand the contemporary interdisciplinary discourse in the science of emotion as a debate between four fundamental types of theories of emotion—realism, instrumentalism, eliminative-realism, and eliminativism—and which can be found or potentially found across the disciplines, and by arguing for foundational principles which can unify, without consilience, these four kinds of approaches as perspectives about the same object of inquiry. It also covers a wide range of concerns, including the problem of skepticism in the science of emotion, the problem of the underdetermination of a theory by the evidence, the question of the place of ordinary intuitions and ordinary language for a science of emotion, the mind-body problem, the hard problem of consciousness, the meta-hard problem of consciousness, the problem of intentionality, questions about the rationality of emotions and whether emotions can be a vehicle for knowledge, and the debate between cognitive and noncognitive theories in the philosophy of emotion.

This book reports on the results of the third edition of the premier conference in the field of philosophy of artificial intelligence, PT-AI 2017, held on November 4 - 5, 2017 at the University of Leeds, UK. It covers: advanced knowledge on key AI concepts, including complexity, computation, creativity, embodiment, representation and superintelligence; cutting-edge ethical issues, such as the AI impact on human dignity and society, responsibilities and rights of machines, as well as AI threats to humanity and AI safety; (...) and cutting-edge developments in techniques to achieve AI, including machine learning, neural networks, dynamical systems. The book also discusses important applications of AI, including big data analytics, expert systems, cognitive architectures, and robotics. It offers a timely, yet very comprehensive snapshot of what is going on in the field of AI, especially at the interfaces between philosophy, cognitive science, ethics and computing. (shrink)

In light of recent breakneck pace in machine learning, questions about whether near-future artificial systems might be conscious and possess moral status are increasingly pressing. This paper argues that as matters stand these debates lack any clear criteria for resolution via the science of consciousness. Instead, insofar as they are settled at all, it is likely to be via shifts in public attitudes brought about by the increasingly close relationships between humans and AI users. Section 1 of the paper I (...) briefly lays out the current state of the science of consciousness and its limitations insofar as these pertain to machine consciousness, and claims that there are no obvious consensus frameworks to inform public opinion on AI consciousness. Section 2 examines the rise of conversational chatbots or Social AI, and argues that in many cases, these elicit strong and sincere attributions of consciousness, mentality, and moral status from users, a trend likely to become more widespread. Section 3 presents an inconsistent triad for theories that attempt to link consciousness, behaviour, and moral status, noting that the trends in Social AI systems will likely make the inconsistency of these three premises more pressing. Finally, Section 4 presents some limited suggestions for how consciousness and AI research communities should respond to the gap between expert opinion and folk judgment. (shrink)

It seems certain to me that I will die and stay dead. By “I”, I mean me, Greg Nixon, this person, this self-identity. I am so intertwined with the chiasmus of lives, bodies, ecosystems, symbolic intersubjectivity, and life on this particular planet that I cannot imagine this identity continuing alone without them. However, one may survive one’s life by believing in universal awareness, perfection, and the peace that passes all understanding. Perhaps, we bring this back with us to the Source (...) from which we began, changing it, enriching it. Once we have lived – if we don’t choose the eternal silence of oblivion by life denial, vanity, indifference, or simple weariness – the Source learns and we awaken within it. Awareness, consciousness, is universal – it comes with the territory – so maybe you will be one of the few prepared to become unexpectedly enlightened after the loss of body and self. You may discover your own apotheosis – something you always were, but after a lifetime of primate experience, now much more. Since you are of the Source and since you have changed from life experience and yet retained the dream of ultimate awakening, plus you have brought those chaotic emotions and memories back to the Source with you (though no longer yours), your life & memories will have mattered. Those who awaken beyond the death of self will have changed Reality. (shrink)

What happens to the inner light of consciousness with the death of the individual body and brain? Reductive materialism assumes it simply fades to black. Others think of consciousness as indicating a continuation of self, a transformation, an awakening or even alternatives based on the quality of life experience.

Does the self exist? If so, what is its nature? How long do selves last? Galen Strawson draws on literature and psychology as well as philosophy to discuss various ways we experience having or being a self.

According to David Chalmers, the hard problem of consciousness consists of explaining how and why qualitative experience arises from physical states. Moreover, Chalmers argues that materialist and reductive explanations of mentality are incapable of addressing the hard problem. In this chapter, I suggest that Chalmers’ hard problem can be usefully distinguished into a ‘how question’ and ‘why question,’ and I argue that evolutionary biology has the resources to address the question of why qualitative experience arises from brain states. From this (...) perspective, I discuss the different kinds of evolutionary explanations (e.g., adaptationist, exaptationist, spandrel) that can explain the origins of the qualitative aspects of various conscious states. This argument is intended to clarify which parts of Chalmers’ hard problem are amenable to scientific analysis. (shrink)

This dissertation concerns the foundations of epistemic modality. I examine the nature of epistemic modality, when the modal operator is interpreted as concerning both apriority and conceivability, as well as states of knowledge and belief. The dissertation demonstrates how phenomenal consciousness and gradational possible-worlds models in Bayesian perceptual psychology relate to epistemic modal space. The dissertation demonstrates, then, how epistemic modality relates to the computational theory of mind; metaphysical modality; deontic modality; logical modality; the types of mathematical modality; to the (...) epistemic status of undecidable propositions and abstraction principles in the philosophy of mathematics; to the apriori-aposteriori distinction; to the modal profile of rational propositional intuition; and to the types of intention, when the latter is interpreted as a modal mental state. Examining the nature of epistemic logic itself, I develop a novel approach to conditions of self-knowledge in the setting of the modal μ-calculus, as well as novel epistemicist solutions to Curry's, the liar, and the knowability paradoxes. Solutions to previously intransigent issues concerning the first-person concept; the distinction between fundamental and derivative truths; and the unity of intention and its role in decision theory, are developed along the way.

It is widely accepted that supervenience is a minimal commitment of physicalism. In this article, however, I aim to argue that physicalism should be exempted from the supervenience requirement. My arguments rely on a parallel between ontological dependence and causal dependence. Since causal dependence does not require causal determination, ontological dependence should not require ontological determination either. Moreover, my approach has a significant theoretical advantage: if physicalism is not committed to supervenience, then the metaphysical possibility of zombies—which is still wide (...) open after all these years—would pose no challenge to physicalism.

Although physicalism is a dominant position in contemporary philosophy of mind and metaphysics, there are surprisingly very few serious arguments for physicalism, which may contribute to the revival of anti-physicalism in recent decades. In this article, I develop a causal argument for physicalism in general, inspired by the causal argument for reductive physicalism. By comparing each pair of premises, I argue that, while the causal argument for reductive physicalism is controversial, the causal argument for physicalism simpliciter is promising.

Nowadays, physicalism is arguably the received view on the nature of mental states. Among the arguments that have been provided in its favour, the inductive one seems to play a pivotal role in the debate. Leveraging the past success of materialistic science, the physicalist argues that a materialistic account of consciousness will eventually be provided, hence that physicalism is true. This article aims at evaluating whether this strategy can provide support for physicalism. According to the standard objection raised against the (...) inductive line of reasoning, the argument would beg the question by assuming some sort of metaphysical uniformity between consciousness and the rest of the natural domain. Here, I concede that there is a way to avoid this criticism. However, I argue that the argument still fails to support physicalism due to a structural problem of justification transmission. (shrink)

In Feeling of Knowing cases, subjects have a form of consciousness about the presence of a content (such as an item of information) without having access to it. If this phenomenon can be correctly interpreted as having to do with consciousness, then there would be a P-conscious mental experience which is dissociated from access.

If we want to assess whether or not a naturalized phenomenology is a desideratum or a category mistake, we need to be clear on precisely what notion of phenomenology and what notion of naturalization we have in mind. In the article I distinguish various notions, and after criticizing one type of naturalized phenomenology, I sketch two alternative takes on what a naturalized phenomenology might amount to and propose that our appraisal of the desirability of such naturalization should be more positive, (...) if we opt for one or both of the latter alternatives.

Some cases of prosopagnosia involve a highly circumscribed loss of A-consciousness. When seen in this way they offer further support for the arguments made in Block's target article.

Today, when it comes to soul-body dualism, the view that comes to mind is the substance dualism that Descartes systematized. As the name suggests, this dualism implies that there are two different types of substances. Similarly, although Ibn Sīnā also adopted a kind of substance dualism by stating that the soul is a different type of substance than matter, his dualism differs from Descartes’ in important aspects. It can be said that the most important reason for this difference is that (...) both ideas belong to different traditions. While Ibn Sīnā’s dualism carries the traces of Aristotelian hylomorphism, Cartesian thought is built on the post-Newtonian understanding of the mechanical universe. This significant difference has deeply affected soul-body conception of both philosophers. The aim of this study is to reveal the fundamental differences between the dualistic understandings of these philosophers in the context of soul-body. Thus, it will become clearer where the Avicennian dualism stands in terms of contemporary philosophy of mind. In this context, the first question to be addressed here is whether, according to both philosophers, the immaterial part of man means the same thing. The answer to this question is negative. The functions that Ibn Sīnā and Descartes attribute to the immaterial substance are quite different from each other. According to Descartes, it can be said that the soul is actually identical with the mind. Because, he describes the soul as the substance whose essence is to think. Here, Descartes is not only referring to theoretical calculations by thinking. It also includes phenomenal consciousness, that is, conscious phenomena, which is also called qualia in contemporary philosophy of mind. Thus, according to the Cartesian tradition, the fundamental distinction between soul/mind (the immaterial substance) and body is phenomenal consciousness: A thing is a soul only if it can have phenomenal consciousness. Whereas, Ibn Sīnā does not see phenomenal consciousness, which is the most basic function that the present Cartesian dualist tradition attributes to the soul, as the basic function of the immaterial substance. In fact, he does not even see it as a function of the human nafs. In other words, according to him, the main function of the human nafs is not to feel/experience or to have phenomenal consciousness. Such functions can also be performed by animals that do not have an immaterial substance. According to Ibn Sīnā, the main functions of the human soul are theoretical or universal thinking and being self-conscious. One of the places where this distinction can be seen most clearly is their thoughts about animal souls. Both philosophers argue that animals do not have an immaterial substance in addition to their material bodies. However, while this means that animals are unconscious automatons for one philosopher (Descartes), it does not mean anything like that for the other. Because, according to Avicenna, an immaterial substance is not necessary to have consciousness or feeling. However, according to Descartes, for a being to be conscious or sentient requires it to have an immaterial substance. Since animals do not have such (substantial) souls, Descartes saw them as unconscious robots. Another point where the same difference can be observed is an argument put forward by Avicenna to prove this immaterial substance, which he addresses as the human soul. According to Avicenna’s argument, the existence of an immaterial substance is necessary for man’s access to universal knowledge, not for having consciousness. However, according to the argument used in the Cartesian tradition and known as the unity of consciousness argument, the existence of immaterial substance is necessary for the unity of consciousness (not knowledge). The aim of this study is to reveal the basic differences between the dualistic understandings of these philosophers in the context of soul and body. In order to reveal these differences, the following points will be discussed: The question of whether animals are conscious and Avicenna’s argument mentioned above. Because the differences in the handling of these two issues by both philosophers will guide us to reveal the fundamental differences in their dualistic understanding. In this study, it will be argued that the dualistic understanding of Avicenna and Descartes in the context of soul-body are radically different from each other, especially over these two issues.

The majority of physicalists are type-B physicalists – believing that the phenomenal-physical truths are only knowable a posteriori. This paper aims to show why this view is misguided. The strategy is to design an agent who (1) has full general physical knowledge, (2) has phenomenal concepts, and yet (3) is wired such that she would be in a position to immediately work out the phenomenal-physical truths. I argue that this derivation yields a priori knowledge. The possibility of such a creature (...) entails that – contrary to type-B physicalism – there is not an ideal epistemic gap between the phenomenal and the physical truths. Out of this argument against type-B physicalism emerges a positive result: a new and compelling version of type-A physicalism, roughly a type-A phenomenal concept strategy. (shrink)

All living organisms are under stress imposed by their surrounding environments. They must adapt to their stressors to live and survive. At the forefront of this adaptation is a defense system called immunity. Immunity, as the most ancient cognitive apparatus with memory function, is present in all living organisms. In previous reports, minimal cognitive function was defined as a “biologized” concept—namely, perception of elements in a milieu, integration of perceived information, reaction according to integrated information, and memory of that experience. (...) In this study, I aim to explore the essential feature of immunity by synthesizing scientific facts and “metaphysicalizing” them with logical reasoning. As a result of my analysis, I have realized the essential element in immunity: the capacity to preserve the existence of organisms by regulating their physiology and pathology. Having further analyzed immunity with special reference to the philosophy of Baruch Spinoza and George Canguilhem, _conatus_ (“appetite”, to be precise) with normative activities is deeply embedded in immunity and may constitute its essential feature. Given that _conatus_ and normativity imply mental elements, including the judgment of good and bad or health and disease, it is possible to conclude that the essential function of immunity includes cognition with normative connotations. This inclusive view encourages us to rethink the fundamental nature and philosophical implications of immunity from the cognitive perspective. (shrink)

This paper examines the relevance of philosophical work on consciousness to its scientific study. Of particular concern is the debate over whether consciousness can be naturalized, which is typically taken to have consequences for the prospects for its scientific investigation. It is not at all clear that philosophers of consciousness have properly identified and evaluated the assumptions about scientific activity made by both naturalization and anti- naturalization projects. I argue that there is good reason to think that some of the (...) assumptions about physicalism and explanation made by the parties to the debate are open to serious doubt. Thus this paper is an invitation for those inquiring into whether consciousness can be naturalized to more carefully consider the expected payoff of such efforts. (shrink)

This paper argues that the form of explanation at issue in the hard problem of consciousness is scientifically irrelevant, despite appearances to the contrary. In particular, it is argued that the 'sense of understanding' that plays a critical role in the form of explanation implicated in the hard problem provides neither a necessary nor a sufficient condition on satisfactory scientific explanation. Considerations of the actual tools and methods available to scientists are used to make the case against it being a (...) necessary condition, and work by J.D. Trout that exploits psychological research on the hindsight and overconfidence biases is used to show that it is not a sufficient condition. It is argued, however, that certain intellectual and moral concerns give us good reason to still try to meet the hard problem's explanatory challenge, despite its extrascientific nature. (shrink)

: In this paper I argue that Velmens’ reflexive model of perceptual consciousness is useful for understanding the first-person perspective and sentience in animals. I then offer a defense of the proposal that ray-finned bony fish have a first-person perspective and sentience. This defense has two prongs. The first prong is presence of a substantial body of evidence that the neuroanatomy of the fish brain exhibits basic organizational principles associated with consciousness in mammals. These principles include a relationship between a (...) second-order sensory relay, the preglomerular complex, and the fish pallium which bears a resemblance to the relationship between the mammalian thalamus and the neocortex, the existence of feedback/feedforward and reentrant circuitry in the pallium, and structural and functional differences among divisions of the fish pallium. The second prong is the existence of behaviors in fish that exhibit significant flexibility in the presence of environmental change and require relational learning among stimuli distributed in space, over time, or both. I conclude that, although they are instantiated differently, a first-person perspective and sentience are present in fish. Resumo: Neste artigo, argumento que o modelo reflexivo de consciência perceptiva de Velmans é útil para se entender a perspectiva de primeira pessoa e a sentiência em animais. Em seguida, ofereço uma defesa da proposta de que os peixes ósseos com nadadeiras raiadas tenham sentiência e perspectiva de primeira pessoa. Esta defesa tem dois momentos. O primeiro ponto é a presença de um corpo substancial de evidências de que a neuroanatomia do cérebro de peixes exibe os princípios organizacionais básicos associados à consciência em mamíferos. Esses princípios incluem a interação entre um relê sensorial de segunda ordem e o pálio, os quais apresentam, respectivamente, estreita semelhança com o tálamo e o neocórtex dos mamíferos; a existência de circuitos de retroalimentação e reentrada, assim como diferenças estruturais e funcionais entre as divisões do pálio. A segunda questão é a existência de comportamentos de peixes que exibem flexibilidade significativa na presença de mudanças ambientais e requerem aprendizado relacional entre estímulos distribuídos no espaço, ao longo do tempo, ou ambos. Concluo que, embora sejam instanciados de maneira diferente dos mamíferos, uma perspectiva de primeira pessoa e sentiência estão presentes nos peixes. (shrink)

I respond to Ned Block’s claim that it is ridiculous to suppose that consciousness is a cultural construction based on language and learned in childhood. Block is wrong to dismiss social constructivist theories of consciousness on account of it being ludicrous that conscious experience is anything but a biological feature of our animal heritage, characterized by sensory experience, evolved over millions of years. By defending social constructivism in terms of both Julian Jaynes’ behaviorism and J.J. Gibson’s ecological psychology, I draw (...) a distinction between the experience or what-it-is-like of nonhuman animals engaging with the environment and the secret theater of speechless monologue that is familiar to a linguistically competent human adult. This distinction grounds the argument that consciousness proper should be seen as learned rather than innate and shared with nonhuman animals. Upon establishing this claim, I defend the Jaynesian definition of consciousness as a social–linguistic construct learned in childhood, structured in terms of lexical metaphors and narrative practice. Finally, I employ the Jaynesian distinction between cognition and consciousness to bridge the explanatory gap and deflate the supposed hard problem of consciousness. (shrink)

Note: this is the first published presentation and defense of the 'proper subset strategy' for making sense of non-reductive physicalism or the associated notion of realization; this is sometimes, inaccurately, called "Shoemaker's subset strategy"; if people could either call it the 'subset strategy' or better yet, add my name to the mix I would appreciate it. Horgan claims that physicalism requires "superdupervenience" -- supervenience plus robust ontological explanation of the supervenient in terms of the base properties. I argue that Horgan's (...) account fails to rule out physically unacceptable emergence. I rather suggest that this and other unacceptable possibilities may be ruled out by requiring that each individual causal power in the set associated with a given supervenient property be numerically identical with a causal power in the set associated with its base property. I go on to show that a wide variety of physicalist accounts, both reductive and non-reductive, are implicitly or explicitly designed to meet this condition, and so are more similar than they seem. In particular, non-reductive physicalism accounts typically appeal to a relation plausibly ensuring that the powers of a higher-level property are a proper subset of those of its physical base property.

Russell and others have argued that the real nature of colour is transparentto us in colour vision. It's nature is fully revealed to us and no further knowledgeis theoretically possible. This is the doctrine of revelation. Two-dimensionalFourier analyses of coloured checkerboards have shown that apparently simple,monadic, colours can be based on quite different physical mechanisms. Experimentswith the McCollough effect on different types of checkerboards have shown thatidentical colours can have energy at the quite different orientations of Fourierharmonic components but no (...) energy at the edges of the checkerboards, thusrefuting revelation. It is concluded that this effect is not explained by a superveniencedispositional account of colour as proposed by McGinn . It was argued that theMcCollough effect in checkerboards was an example of a local mind/body reduction, by which the different characteristics of identical colours falsifies revelation. This reduction being based on both physical and neurological mechanisms led to a clear explanation of the perceive phenomenal effects and thus laid a small bridge over the explanatory gap. (shrink)

Chalmers (The Conscious Mind, Oxford Unversity Press, Oxford 1996) has argued for a form of property dualism on the basis of the concept of a zombie (which is physically identical to normals), and the concept of the inverted spectrum. He asserts that these concepts show that the facts about consciousness, such as experience or qualia, are really further facts about our world, over and above the physical facts. He claims that they are the hard part of the mind-body issue. He (...) also claims that consciousness is a fundamental feature of the world like mass, charge, etc.He says that consciousness does not logically supervene on the physical and all current attempts to assert an identity between consciousness and the physical are just as non-reductive as his dualism. They are simply correlations and are part of the problem of the explanatory gap. In this paper, three examples of strong identities between a sensation or a quale and a physiological process are presented, which overcome these problems. They explain the identity in an a priori manner and they show that consciousness or sensations (Q) logically supervene on the physical (P), in that it is logically impossible to have P and not to have Q. In each case, the sensation was predicted and entailed by the physical. The inverted spectrum problem for consciousness is overcome and explained by a striking asymmetry in colour space. It is concluded that as some physical properties realize some sensations or qualia that human zombies are not metaphysically possible and the explanatory gap is bridged in these cases. Thus, the hard problem is overcome in these instances. (shrink)

Based on the technique of pressure blinding of the eye, two types of after-image were identified. A physicalist or mind/brain identity explanation was established for a negative a AI produced by moderately intense stimuli. These AI's were shown to be located in the neurons of the retina. An illusory AI of double a grating's spatial frequency was also produced in the same structure and was both prevented from being established and abolished after establishment by pressure blinding, thus showing that the (...) location was not more central. The illusory AI was predicted from the known non-linearity in the retina and this is the first case of a clear cut type-type identity of a sensation and a neural process. Some implications for the concepts of the explanatory gap between neurology and consciousness and multiple neural realizations of conscious states and topic neutrality are discussed. (shrink)

Block has attempted to reduce the confusion and controversy concerning the term “consciousness” by suggesting that there are two forms or types of consciousness, each of which has several characteristics or properties. This suggestion appears to further becloud the topic, however. Perhaps consciousness cannot be defined adequately and should not be considered as a topic that can be studied scientifically.

Since the end of the last century, there has been several ambitious attempts to naturalize Husserlian phenomenology by way of mathematization. To justify themselves in view of Husserl’s adamant antinaturalism, many of these attempts appeal to the new physico-mathematical tools that were unknown in Husserl’s time and thus allegedly make his position outdated. This paper critically addresses these mathematization proposals and aims to show that Husserl had, in fact, sufficiently good arguments that make his antinaturalistic position sound even today. The (...) starting point of the discussion presented in this paper is the mathematization project introduced by Jean-Michel Roy, Jean Petitot, Bernard Pachoud, and Francisco Varela in their introduction to the book Naturalizing Phenomenology. This proposal was followed by a number of critiques but also by several alternative naturalization attempts clearly inspired by Roy et al.’s ambitious project. The review of some of Husserl’s important arguments often overlooked or misinterpreted by both the naturalization advocates and their critics leads the author of the paper to the twofold conclusion which, on the one hand, explores the deeper reasons for the impossibility of a physical and mathematical treatment of phenomenology, on the other hand, clarifies the sense in which such treatments are possible, namely by way of restriction of the variety of experiential aspects that undergo naturalization and substitution of the aspects amenable to the direct mathematization for the directly unmathematizable ones. In the fourth section of this paper, the author attempts to demonstrate that, contrary to widespread belief, Husserl’s arguments are not obsolete by the standards of the contemporary physico-mathematical approaches employed in the mathematization of phenomenology and indeed stand the test of time.

Abstract. Contrary to proposals that seek a harmonious integration of “science and religion” or “science and spirituality,” I argue that contemporary scientific and philosophical work at the mind-brain interface gives us reason to be skeptical of many of the claims found within religious spiritualities. Religious spiritualities typically presume commitment to strong versions of metaphysical dualism, while contemporary mind science gives us every reason to think that the mind is the brain. If materialism is true, what becomes of spirituality? Materialism or (...) naturalism is widely understood to be an anti-religious position with corrosive effects on morality. I correct this impression, arguing that materialism offers a compelling account of moral objectivity and is fully compatible with an appreciation for many aspects of religion. I further suggest that nothing precludes dialogue and conversation between naturalists and religious believers. (shrink)
