Phenomenal intentionality is a kind of intentionality, or aboutness, that is grounded in phenomenal consciousness, the subjective, experiential feature of certain mental states. The phenomenal intentionality theory (PIT), is a theory of intentionality according to which there is phenomenal intentionality, and all other kinds of intentionality at least partly derive from it. In recent years, PIT has increasingly been seen as one of the main approaches to intentionality.

A central task of philosophy of mind in recent decades has been to come up with a comprehensive account of the mind that is consistent with materialism. To this end, philosophers have offered useful reductive accounts of mentality in terms that are ultimately explainable by neurobiology. Although these accounts have been useful for explaining some psychological states, one feature—phenomenality or consciousness—has proven to be particularly intractable. The Higher-Order Thought theory (HOT) has been offered as one reductive theory of consciousness. According (...) to HOT, a mental state is conscious if it becomes the content of a suitable higher-order thought that one is in that mental state. In recent years, critics have lodged a series of challenging objections to the view and several alternative theories have been proposed in response to these objections. This paper offers a defense of the traditional Higher-Order Thought theory. First, two different models of consciousness based on HOT are distinguished. The paper argues that one of the models is better supported by the HOT literature. It is then demonstrated that the better supported model is not vulnerable to the objections most commonly lodged against the HOT theory. Finally, it is shown that alternative self-representational theories do not improve upon the HOT theory in the way that they are proposed to. In fact, each of the alternative self-representational views reviewed here is vulnerable to a unique set of problems. In light of these factors, HOT still offers a viable reductive solution to the hard problem. (shrink)

Although panpsychism has had a very long history, one that goes back to the very origin of western philosophy, its force has only recently been appreciated by analytic philosophers of mind. And even if many still reject the theory as utterly absurd, others have argued that it is the only genuine form of physicalism. This paper examines the case for panpsychism and argues that there are at least goodprima faciereasons for taking it seriously. In a second step, the paper discusses (...) the main difficulty the theory has to face, the ‘composition problem’. This is the problem of explaining how the primitive experiences that are supposed to exist at the ultimate level of reality could give rise to the unified experience of a human being. What assumptions as to the nature of experience generate the composition problem? Is mental composition impossible in principle or do we simply lack at present any understanding of phenomenal parts and wholes? (shrink)

Recently, some philosophers have suggested that a form of robust realism about ethics, or normativity more generally, does not face a significant explanatory burden in metaphysics. I call this view metaphysically quietist normative realism . This paper argues that while this view can appear to constitute an attractive alternative to more traditional forms of normative realism, it cannot deliver on this promise. I examine Scanlon’s attempt to defend such a quietist realism, and argue that rather than silencing metaphysical questions about (...) normative reasons, his defense at best succeeds only in shifting the focus of metaphysical enquiry. I then set aside the details of Scanlon’s view, and argue on general grounds that that the quietist realist cannot finesse a crucial metanormative task: to explain the contrast between the correct normative system and alternative putatively normative standards.

How has multiplicity superseded impossibility in philosophical challenges to artificial consciousness? I assess a trajectory in recent debates on artificial consciousness, in which metaphysical and explanatory challenges to the possibility of building conscious machines lead to epistemological concerns about the multiplicity underlying ‘what it is like’ to be a conscious creature or be in a conscious state. First, I analyse earlier challenges which claim that phenomenal consciousness cannot arise, or cannot be built, in machines. These are based on Block’s Chinese (...) Nation and Chalmers’ Hard Problem. To defuse such challenges, theorists of artificial consciousness can appeal to empirical methods and models of explanation. Second, I explain why this naturalistic approach produces an epistemological puzzle on the role of biological properties in phenomenal consciousness. Neither behavioural tests nor theoretical inferences seem to settle whether our machines are conscious. Third, I evaluate whether the new challenge can be managed through a more fine-grained taxonomy of conscious states. This strategy is supported by the development of similar taxonomies for biological species and animal consciousness. Although it makes sense of some current models of artificial consciousness, it raises questions about their subjective and moral significance. (shrink)

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)

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

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 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.

In his book The Conscious Mind David Chalmers introduced a by now familiar distinction between the hard problem and the easy problems of consciousness. The easy problems are those concerned with the question of how the mind can process information, react to environmental stimuli, and exhibit such capacities as discrimination, categorization, and introspection (Chalmers, 1996, 4, 1995, 200). All of these abilities are impressive, but they are, according to Chalmers, not metaphysically baffling, since they can all be tackled by means (...) of the standard repertoire of cognitive science and explained in terms of computational or neural mechanisms. This task might still be difficult, but it is within reach. In contrast, the hard problem—also known as the problem of consciousness (Chalmers, 1995, 201)—is the problem of explaining why mental states have phenomenal or experiential qualities. Why is it like something to ‘taste coffee’, to ‘touch an ice cube’, to ‘look at a sunset’ etc.? Why does it feel the way it does? Why does it at all feel like anything? Chalmers’s distinction confronts us with a version of the so-called ‘explanatory gap’. On the one hand, we have certain cognitive functions, which can apparently be explained reductively, and on the other hand, we have a number of experiential qualities, which seem to resist this reductive explanation. We can establish that a certain function is accompanied by a certain experience, but we have no idea why that happens, and regardless of how closely we scrutinize the neural mechanisms we don’t seem to be getting any closer at an answer. In his book, Chalmers also distinguished two concepts of mind: a phenomenal concept and a psychological concept. The first captures the conscious aspect of mind: Mind is understood in terms of conscious experience. The second concept understands mind in functional terms as the causal or explanatory basis for behavior.. (shrink)

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.

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 we should not ascribe beliefs and desires to subjects like zombies or (present day) computers which do not have phenomenal consciousness. In order to ascribe beliefs, we must distinguish between personal and subpersonal content. There may be states in my brain which represent the array of light intensities on my retina, but these states are not beliefs, because they are merely subpersonal. I argue that we cannot distinguish between personal and subpersonal content without reference (...) to phenomenal consciousness. I argue for this by examining two attempts to account for belief without reference to phenomenal consciousness, functionalism and Dennett's patterns of behavior theory, and showing that they both fail. In the course of the arguments that these attempts fail, I develop some positive reasons for believing that phenomenal consciousness is indeed necessary. (shrink)

Fodor's thinking on modularity has been influential throughout a range of the areas studying cognition, chiefly as a prod for positive work on modularity and domain-specificity. In _The Mind Doesn't Work That Way_, Fodor has developed the dark message of _The Modularity of Mind_ regarding the limits to modularity and computational analyses. This paper offers a critical assessment of Fodor's scepticism with an eye to highlighting some broader issues in play, including the nature of computation and the role of recent (...) empirical developments in the cognitive sciences in assessing Fodor's position.

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.

The evidence of blindsight is occasionally used to argue that we can see things, and thus have perceptual belief, without the distinctive visual awareness accompanying normal sight; thereby displacing phenomenality as a component of the concept of vision. I maintain that arguments to this end typically rely on misconceptions about blindsight and almost always ignore associated visual (or visuomotor) pathologies relevant to the lessons of such cases. More specifically, I conclude, first, that the phenomena very likely do not result from (...) dissociations within a single system, but from the interaction of evolutionarily distinct, if interacting, systems; second, that a closer study of spared motor abilities indicates that verbal responses of patients result not from degraded vision but from proprioception; and, finally, above chance verbal responses, being forced guesses, are not tentative beliefs and cannot become beliefs just by training patients to have more confidence in their responses.

In the visual system, the represented features of individual objects (shape, colour, movement, and so on) are distributed both in space and time within the brain. Representations of inner and outer event sequences arrive through different sense organs at different times, and are likewise distributed. Objects are nevertheless perceived as integrated wholes - and event sequences are experienced to form a coherent "consciousness stream." In their thoughtful article, Dennett & Kinsbourne ask how this is achieved.

Blocks distinction between “phenomenal feel” consciousness and “thought/cognition” consciousness is a cultural construction. Consciousness (and its “subspecies”) is not a natural kind. Some crosscultural data are presented to support this.

It is argued that there is no fallacy in the reasoning in the example of the thirsty blindsight subject, on one reconstruction of that reasoning. Neither the case of orgasm nor the case of a visual versus an auditory experience as of something overheard shows that phenomenal content is not representational.

One standard objection to the view that phenomenal experience is functionally determined is based upon what has come to be called ‘The Absent Qualia Hypothesis’, the idea that there could be a person or a machine that was functionally exactly like us but that felt or consciously experienced nothing at all . Advocates of this hypothesis typically maintain that we can easily imagine possible systems that meet the appropriate functional specifications but that intuitively lack any phenomenal consciousness. Ned Block , (...) for example, asks us to suppose that a billion Chinese people are each given a two-way radio with which to communicate with one another and with an artificial body. The movements of the body are controlled by the radio signals, and the signals themselves are made in accordance with instructions the Chinese people receive from a vast display in the sky which is visible to all of them. The instructions are such that the participating Chinese people together realize whatever programs the functionalist supposes underlie human phenomenal experience. (shrink)

This paper discusses recent neuroscientific research that indicates a solution for what we label the ''causal problem'' of pain qualia, the problem of how the brain generates pain qualia. In particular, the data suggest that pain qualia naturally supervene on activity in a specific brain region: the anterior cingulate cortex (ACC). The first section of this paper discusses several philosophical concerns regarding the nature of pain qualia. The second section overviews the current state of knowledge regarding the neuroanatomy and physiology (...) of pain processing. The third section highlights the recent research by Rainville et al. [(1997) Pain affect encoded in human anterior cingulate but not somatosensory cortex, Science, 277, 968-971], which suggests that pain affect is encoded in the ACC. The final section of the paper spells out exactly how these data affect the causal problem of pain qualia. (shrink)

We argue that Kant’s views about consciousness, the mind-body problem, and the status of psychology as a science all differ drastically from the way in which these topics are conjoined in present debates about the prominent idea of a science of consciousness. Kant did never use the concept of consciousness in the now dominant sense of phenomenal qualia; his discussions of the mind-body problem center not on the reducibility of mental properties but of substances; and his views about the possibility (...) of psychology as a science did not employ the requirement of a mechanistic explanation, but of quantification of phenomena. This shows strikingly how deeply philosophical problems and conceptions can change even if they look similar on the surface. (shrink)

This paper takes up the critique of armchair philosophy drawn by some experimental philosophers from survey results. It also takes up a more recent development with increased methodological sophistication. The argument based on disagreement among respondents suggests a much more serious problem for armchair philosophy and puts in question the standing of our would-be discipline.

If phenomenal consciousness is distinct from the computationally based access-consciousness that controls overt behavior, how can I tell which things (other than myself) enjoy phenomenal consciousness? And if phenomenal consciousness 'plays no role in controlling overt behavior, how do human bodies come to write target articles arguing for the existence of phenomenal consciousness?

Neuropsychological results are increasingly cited in cognitive theories although their methodology has been severely criticised. The book argues for an eclectic approach but particularly stresses the use of single-case studies. A range of potential artifacts exists when inferences are made from such studies to the organisation of normal function – for example, resource differences among tasks, premorbid individual differences, and reorganisation of function. The use of “strong” and “classical” dissociations minimises potential artifacts. The theoretical convergence between findings from fields where (...) cognitive neuropsychology is well developed and those from the normal literature strongly suggests that the potential artifacts are not critical. The fields examined in detail in this respect are short-term memory, reading, writing, the organisation of input and output speech systems, and visual perception. Functional dissociation data suggest that not only are input systems organised modularly, but so are central systems. This conclusion is supported by findings on impairment of knowledge, visual attention, supervisory functions, memory, and consciousness. (shrink)

Seeing, hearing and touching are phenomenally different, even if we are detecting the same spatial properties with each sense. This presents a prima facie problem for intentionalism, the theory that phenomenal character supervenes on representational content. The paper reviews some attempts to resolve this problem, and then looks in detail at Peter Carruthers' recent proposal that the senses can be individuated by the way in which they represent spatial properties and incorporate time. This proposal is shown to be ineffective in (...) distinguishing auditory from either visual or tactual perception, and substantial classes of visual and tactual perceptions are found that the posited spatial and temporal features fail to individuate.

The purpose of this article is to show why consciousness and thought are not manifested in digital computers. Analyzing the rationale for claiming that the formal manipulation of physical symbols in Turing machines would emulate human thought, the article attempts to show why this proved false. This is because the reinterpretation of designation and meaning to accommodate physical symbol manipulation eliminated their crucial functions in human discourse. Words have denotations and intensional meanings because the brain transforms the physical stimuli received (...) from the microworld into a qualitative, macroscopic representation for consciousness. Lacking this capacity as programmed machines, computers have no representations for their symbols to designate and mean. Unlike human beings in which consciousness and thought, with their inherent content, have emerged because of their organic natures, serial processing computers or parallel distributed processing systems, as programmed electrical machines, lack these causal capacities.

Phenomenal consciousness, what it is like to have or undergo an experience, is typically understood as an empirical item – an actual or possible object of consciousness. Accordingly, the problem posed by phenomenal consciousness for materialist accounts of the mind is usually understood as an empirical problem: a problem of showing how one sort of empirical item – a conscious state – is produced or constituted by another – a neural process. The development of this problem, therefore, has usually consisted (...) in the articulation of an intuition: no matter how much we know about the brain, this will not allow us to see how it produces or constitutes phenomenal consciousness. Developing a theme first explored by Kant, and then later by Sartre, this paper argues that the real problem posed by phenomenal consciousness is quite different. Consciousness, it will be argued, is not an empirical but a transcendental feature of the world. That is, what it is like to have an experience is not something of which we are aware in the having of that experience, but an item in virtue of which the genuine objects of our consciousness are revealed as being the way they are. Phenomenal consciousness, that is, is not an empirical object of awareness but a transcendental condition of the possibility of there being empirical objects of awareness. (shrink)
