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)

In their update to Intentionality All-Stars, Hutto and Satne claim that there is currently no satisfactory account for a naturalised conception of content. From this the pair suggest that we need to consider whether content is present in all aspects of intelligence, that is, whether it is content all the way down. Yet if we do not have an acceptable theory of content such a question seems out of place. It seems more appropriate to question whether content itself is the (...) problematic assumption. This paper will explore this question, with the analysis hinging on whether those trying to naturalise content are facing a tough challenge as Haugeland has suggested, or whether it is a genuine dilemma as Hutto has suggested elsewhere. If those attempting to naturalise content are facing a genuine dilemma, a dilemma in which the non-existence of content is one of the horns, then it would seem that the issue is not at what stage you posit content, but whether you should posit content at all. This also has the added benefit of shifting the debate to a more global discussion, that is, the best way to explain intelligence, period. (shrink)

This critical examination of Roderick Chisholm's agent causal brand of libertarianism develops a problem about luck that undermines his earlier and later libertarian views on free will and moral responsibility and defends the thesis that a modest libertarian alternative considerably softens the problem. The alternative calls for an indeterministic connection in the action-producing process that is further removed from action than Chisholm demands. The article also explores the implications of a relatively new variant of a Frankfurt-style case for Chisholm's views (...) of free will and moral responsibility and for libertarianism in general. It is suggested that Chisholm's efforts will and should continue to offer important assistance to libertarians who are determined to succeed where he apparently fell short. (shrink)

Recently, many philosophers have been inclined to ascribe mentality to animals on the main grounds that they possess certain complex computational abilities. In this paper I contend that this view is misleading, since it wrongly assumes that those computational abilities demand a psychological explanation. On the contrary, they can be just characterised from a computational level of explanation, which picks up a domain of computation and information processing that is common to many computing systems but is autonomous from the domain (...) of psychology. Thus, I propose that it is possible to conceive insects and other animals as mere computing agents, without having any commitment to ascribe mentality to them. I conclude by sketching a proposal about how to draw the line between mere computing and genuine mentality. (shrink)

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

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

Many debates in philosophy focus on whether folk or scientific psychological notions pick out cognitive natural kinds. Examples include memory, emotions and concepts. A potentially interesting type of kind is: kinds of mental representations (as opposed, for example, to kinds of psychological faculties). In this chapter we outline a proposal for a theory of representational kinds in cognitive science. We argue that the explanatory role of representational kinds in scientific theories, in conjunction with a mainstream approach to explanation in cognitive (...) science, suggest that representational kinds are multi-level. This is to say that representational kinds’ properties cluster at different levels of explanation and allow for intra- and inter-level projections. (shrink)

An introduction to functionalism in the philosophy of psychology/mind, and review of the current state of debate pro and con. Forthcoming in the Routledge Companion to the Philosophy of Psychology (John Symons and Paco Calvo, eds.).

In this paper, I argue that theories of perception that appeal to Helmholtz’s idea of unconscious inference (“Helmholtzian” theories) should be taken literally, i.e. that the inferences appealed to in such theories are inferences in the full sense of the term, as employed elsewhere in philosophy and in ordinary discourse. -/- In the course of the argument, I consider constraints on inference based on the idea that inference is a deliberate acton, and on the idea that inferences depend on the (...) syntactic structure of representations. I argue that inference is a personal-level but sometimes unconscious process that cannot in general be distinguished from association on the basis of the structures of the representations over which it’s defined. I also critique arguments against representationalist interpretations of Helmholtzian theories, and argue against the view that perceptual inference is encapsulated in a module. (shrink)

This volume contains 12 papers addressed to researchers and advanced students in informal logic and related fields, such as argumentation, formal logic, and communications. Among the issues discussed are attempts to rethink the nature of argument and of inference, the role of dialectical context, and the standards for evaluating inferences, and to shed light on the interfaces between informal logic and argumentation theory, rhetoric, formal logic and cognitive psychology.

This volume is a collection of some of the most important philosophical papers by Peter Gärdenfors. Spanning a period of more than 20 years of his research, they cover a wide ground of topics, from early works on decision theory, belief revision and nonmonotonic logic to more recent work on conceptual spaces, inductive reasoning, semantics and the evolutions of thinking. Many of the papers have only been published in places that are difficult to access. The common theme of all the (...) papers is the dynamics of thought. Several of the papers have become minor classics and the volume bears witness of the wide scope of Gärdenfors’ research and of his crisp and often witty style of writing. The volume will be of interest to researchers in philosophy and other cognitive sciences. (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)

A comprehensive introduction to the Language of Though Hypothesis (LOTH) accessible to general audiences. LOTH is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, thought is, roughly, the tokening of a representation that has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in (...) syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking. (shrink)

Dramatic changes or revolutions in a field of science are often made by outsiders or 'trespassers,' who are not limited by the established, 'expert' approaches. Each essay in this diverse collection shows the fruits of intellectual trespassing and poaching among fields such as economics, Kantian ethics, Platonic philosophy, category theory, double-entry accounting, arbitrage, algebraic logic, series-parallel duality, and financial arithmetic.

What is the mind? Is consciousness a process in the brain? How do our minds represent the world? Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

It is often held that it is conceptually impossible to distinguish between a pain and a pain experience. In this article I present an argument which concludes that people make this distinction. I have done a web-based statistical analysis which is at the core of this argument. It shows that the intensity of pain has a decisive effect on whether people say that they 'feel a pain'(lower intensities) or 'have a pain' (greater intensities). This 'intensity effect'can be best explained by (...) people's varying confidence about their pain, and indicates that 'feeling pain' can be identified as introspective report and 'having pain' as an objective statement — analogous to the traditional sense modalities. However, if people have the ability to make both introspective and objective statements about pain, then it seems indeed the case that they distinguish the appearance from the reality of pain.

Mental imagery (varieties of which are sometimes colloquially refered to as “visualizing,” “seeing in the mind's eye,” “hearing in the head,” “imagining the feel of,” etc.) is quasi-perceptual experience; it resembles perceptual experience, but occurs in the absence of the appropriate external stimuli. It is also generally understood to bear intentionality (i.e., mental images are always images of something or other), and thereby to function as a form of mental representation. Traditionally, visual mental imagery, the most discussed variety, was thought (...) to be caused by the presence of picturelike representations (mental images) in the mind, soul, or brain, but this is no longer universally accepted.

The main aim of this paper is to investigate what becomes of normativity in naturalistic epistemologies. What particular stand a given naturalistic epistemology takes on normativity will depend both on what it thinks is wrong with traditional epistemology and on what level of normativity is at stake. I propose a tentative typology of possible attitudes towards normativity from within naturalistic epistemology. In section I, I give a brief presentation of traditional epistemology, stressing the dimensions of this approach that may appear (...) problematic to naturalists. In section II, I present and discuss the naturalist project in its radical form, as personified by Quine, who questions not only the way in which traditional epistemology proceeds in order to attain its objectives, but also the validity of these objectives. The last two sections concentrate on more moderate versions of naturalism. Section III investigates the various possible roles that may be assigned to psychology in these moderate forms of naturalism and the ensuingconsequences vis-a-vis the problem of normativity. In section IV, I distinguish between two levels of normativity in epistemology, what I call the normativity of means and the normativity of ends and I discuss the prospects of a naturalization of epistemic ends.

Many philosophers and cognitive scientists claim that our everyday or "folk" understanding of mental states constitutes a theory of mind. That theory is widely called "folk psychology" (sometimes "commonsense" psychology). The terms in which folk psychology is couched are the familiar ones of "belief" and "desire", "hunger", "pain" and so forth. According to many theorists, folk psychology plays a central role in our capacity to predict and explain the behavior of ourselves and others. However, the nature and status of folk (...) psychology remains controversial. (shrink)

Aristotle’s Naïve Somatism is a re-interpretation of Aristotle’s cognitive psychology in light of certain presuppositions he holds about the living animal body. The living animal body is presumed to be sensitive, and Aristotle grounds his account of cognition in a rudimentary proprioceptive awareness one has of her body. With that presupposed metaphysics under our belts, we are in a position to see that Aristotle in de Anima (cognition chapters at least) has a di erent explanatory aim in view than that (...) which the literature generally imputes to him. He is not explicating what we would call the “mental”—the private, inner realm which some take to be of a di erent kind than the physical—as most take him to be. His explanandum is content acquisition; the explanans is showing how the body becomes like various aspects of objects. Although he famously describes the mind (nous) as unmixed with the body, he is guided by functional constrains—nous cannot be limited or qualified if it is to potentially think all things. Thus, his inquiry into cognition is philosophically limited from a contemporary perspective. Aristotle is not doing philosophy of mind, for he doesn’t seem to find the “mental” philosophically perplexing. (shrink)

The identity theory’s rise to prominence in analytic philosophy of mind during the late 1950s and early 1960s is widely seen as a watershed in the development of physicalism, in the sense that whereas logical behaviourism proposed analytic and a priori ascertainable identities between the meanings of mental and physical-behavioural concepts, the identity theory proposed synthetic and a posteriori knowable identities between mental and physical properties. While this watershed does exist, the standard account of it is misleading, as it is (...) founded in erroneous intensional misreadings of the logical positivists’—especially Carnap’s—extensional notions of translation and meaning, as well as misinterpretations of the positivists’ shift from the strong thesis of translation-physicalism to the weaker and more liberal notion of reduction-physicalism that occurred in the Unity of Science programme. After setting the historical record straight, the essay traces the first truly modern identity theory to Schlick’s pre-positivist views circa 1920 and goes on to explore its further development in Feigl, arguing that the fundamental difference between the Schlick-Feigl identity theory and the more familiar and influential Place-Smart-Armstrong identity theory has resurfaced in the deep and seemingly unbridgeable gulf in contemporary philosophy of consciousness between inflationary mentalism and deflationary physicalism.

As a step towards comprehensive computer models of communication, and effective human machine dialogue, some of the relationships between communication and affect are explored. An outline theory is presented of the architecture that makes various kinds of affective states possible, or even inevitable, in intelligent agents, along with some of the implications of this theory for various communicative processes. The model implies that human beings typically have many different, hierarchically organized, dispositions capable of interacting with new information to produce affective (...) states, distract attention, interrupt ongoing actions, and so on. High "insistence" of motives is defined in relation to a tendency to penetrate an attention filter mechanism, which seems to account for the partial loss of control involved in emotions. One conclusion is that emulating human communicative abilities will not be achieved easily. Another is that it will be even more difficult to design and build computing systems that reliably achieve interesting communicative goals. (shrink)

Subjective rightness (or ‘ought’ or obligation) seems to be the sense of rightness that should be action guiding where more objective senses fail. However, there is an ambiguity between strong and weak senses of action guidance. No general account of subjective rightness can succeed in being action guiding in a strong sense by providing an immediately helpful instruction, because helpfulness always depends on the context. Subjective rightness is action guiding in a weaker sense, in that it is always accessible and (...) comprehensible to the agent. Hence traditional belief formulations say roughly, “do what you believe is best.” This is not yet a satisfactory formulation, because it cannot make sense of our ongoing subjective duty to improve our beliefs. The notion of ‘trying’ does capture the dynamic and diachronic nature of our subjective obligation. Thus, we should formulate subjective obligation in terms of trying: “try to do well by morality.”.

Many debates about consciousness appear to be endless, in part because of conceptual confusions preventing clarity as to what the issues are and what does or does not count as evidence. This makes it hard to decide what should go into a machine if it is to be described as 'conscious'. Thus, triumphant demonstrations by some AI developers may be regarded by others as proving nothing of interest because the system does not satisfy *their* definitions or requirements specifications.

The Matrix presents a version of an old philosophical fable: the brain in a vat. A disembodied brain is floating in a vat, inside a scientist’s laboratory. The scientist has arranged that the brain will be stimulated with the same sort of inputs that a normal embodied brain receives. To do this, the brain is connected to a giant computer simulation of a world. The simulation determines which inputs the brain receives. When the brain produces outputs, these are fed back (...) into the simulation. The internal state of the brain is just like that of a normal brain, despite the fact that it lacks a body. From the brain’s point of view, things seem very much as they seem to you and me. (shrink)

This thesis has, as its primary target, the neo-cartesianism, or property dualism of certain philosophers of mind: David Chalmers, Tim Bayne, and others. All begin with a pre-theoretic commitment to the view that all perceptual states are conscious. They define consciousness by saying that it is synonymous with having ‘qualia’ – a term directed at phenomenal properties which defy reduction to physical states. The thesis argues that this position is challenged by certain neurological conditions, - blindsight, visual form agnosia etc- (...) which we can generalise as ‘dissociations’: conditions in which functions are separated from awareness. The thesis holds that these are examples of unconscious perception, which present the case for a different pre-theoretic position, and a redefinition of concepts used in the vicinity. Insofar as the neo-cartesians recognise the empirical, their inclination to reject the dissociations is challenged with new cases and paradigms which have emerged in recent years. It is contended that the dissociations disrupt Chalmers’ coherence between the phenomenal and the psychological, Bayne’s commitment to the Unity of Consciousness, and Phillips’ campaign against unconscious perception. In addition, synaesthesia is advanced as a problem case for Bayne’s unity contention. I argue that the dissociations are not easily dismissed, and present a real challenge for neo-cartesianism. In exploring this challenge, the thesis contributes to the case for a different philosophy of mind – a Higher Order Thought approach. The notion of unconscious perception – it is contended - much more easily finds an accommodation in HOT theories, so this thesis contributes to existing arguments for that position. HOT theories also have an advantage in being receptive to reduction, in giving a developmental account of consciousness, and in being more open to the accommodation of empirical discoveries. In each respect, there is an advantage over the respective positions taken by Chalmers and Bayne. (shrink)

This dissertation seeks to examine the validity of the justification commonly offered for a coercive (1) psychiatric intervention, namely that the intervention was in the ‘best interests’ of the subject and/or that the subject posed a danger to others. As a first step,it was decided to analyse justifications based on ‘best interests’ [the ‘Stage 1’ argument] separately from those based on dangerousness [the ‘Stage 2’ argument]. Justifications based on both were the focus of the ‘Stage 3’ argument. Legal and philosophical (...) analyses of coercive psychiatric interventions generally regard such interventions as embodying a benign paternalism occasioning slight, if any, ethical concern. Whilst there are some dissenting voices even at the very heart of academic and professional psychiatry, the majority of psychiatrists also appear to share such views. The aim of this dissertation is to show that such a perspective is mistaken and that such interventions raise philosophical and ethical questions of the profoundest importance.(2) The philosophical well-spring of the Stage 1 dissertation argument lay in an observation made by Philippa Foot (3) that the “… right to be let free from unwanted interference” is one of the most fundamental and distinctive rights of persons, a right which takes precedence over any “… action we would dearly like to take for his sake.” This – in conjunction with the recognition that some coercive psychiatric interventions are of a gravity as to result in the personhood of the subject being severely damaged if not destroyed – suggested that the concept of personhood play a central role in the formulation of the dissertation argument. For ease of analysis it was presumed that the term ‘person’ could be defined by a set of necessary and sufficient conditions of which ‘minimum levels of rationality’ and ‘ability to communicate’ were the only conditions relevant to the formulation of justifications for coercive psychiatric interventions. This presumption was explicated into a number of postulates which enabled the construction of a rigorous foundation on which to develop the dissertation argument. This argument then sought to determine whether psychiatric assessments of irrationality were accurate and reliable. In furtherance of this analysis it was necessary to examine the reliability of psychiatric determinations in other areas of claimed expertise namely diagnosis, treatment and assessment of dangerousness. This ‘crossing of the disciplinary threshold’ brought to light the dearth of studies on psychiatric misdiagnosis and iatrogenic harm. A variant of the Precautionary Principle was developed to enable the extent of such harms to be estimated. The not insignificant levels of psychiatric misdiagnosis and iatrogenic harm and erroneous assessments of dangerousness which were thus found are of considerable relevance to any ethical analysis of the justification for coercive psychiatric intervention and serve to undermine simple paternalistic justifications. --- (1)The term ‘coercive’ (rather than ‘non-consensual’) is used to indicate an intervention carried out against the explicit and contemporaneous objections of the subject (2)Not least because the number of individuals detained in Irish psychiatric hospitals is of a comparable order of magnitude to the number detained in Irish prisons subsequent to a criminal conviction (3)See Foot (1977), p.102.
