Added by: Nick NovelliAbstract: The claim of the multiple realizability of mental states by brain states has been a major feature of the dominant philosophy of mind of the late 20th century. The claim is usually motivated by evidence that mental states are multiply realized, both within humans and between humans and other species. We challenge this contention by focusing on how neuroscientists differentiate brain areas. The fact that they rely centrally on psychological measures in mapping the brain and do so in a comparative fashion undercuts the likelihood that, at least within organic life forms, we are likely to find cases of multiply realized psychological functions.

Added by: Clotilde Torregrossa, Contributed by: Simon FoktAbstract: What is it like to be a bat? This is one of the most famous questions ever asked in the history of consciousness studies. First posed in 1950 it was made famous in a 1974 paper of that name by American philosopher Thomas Nagel. Nagel argued that understanding how mental states can be neurons firing inside the brain is a problem quite unlike understanding how water canbe H2O, or how genes can be DNA. 'Consciousness is what makes the mind-body problem really intractable,' he said (Nagel, 1974: 435; 1979:165), and by consciousness he meant subjectivity. To make this clear he asked 'What is it like to be a bat?'. Do you think that your cat is conscious? Or the birds outside in the street? Perhaps you believe that horses are conscious but not worms, or living creatures but not stones. We shall return to these questions (Chapter 12) but here let's consider what it means to say that another creature is conscious. If you say that the stone is not conscious you probably mean that it has no inner life and no point of view; that there is nothing it is like to be the stone. If you believe that the neighbour's vicious bloodhound, or the beggar you passed inthe subway, is conscious, then you probably mean that they do have a point of view; there is something it is like to be them. As Nagel put it, when we say that another organism is conscious we mean that 'there is something it is like to be that organism . . . something it is like for the organism' (1974: 436); 'the essence of the belief that bats have experience is that there is something that it is like to be a bat' (ibid.: 438). This is probably the closest we can come to a definition of consciousness - that consciousness is subjectivity, or 'what it is like to be . . .'. Here we must be careful with the phrase 'what it is like . . .'. Unfortunately there are at least two meanings in English. We might say 'this ice cream tastes like rubber' or 'lying on a beach in the sun is like heaven'. In this case we are comparing things, making analogies, or saying what they resemble. This is not what Nagel meant. The other meaning is found in such questions as: What is it like to work at McDonald's? What is it like to be able to improvise fugues at the keyboard?...to be someone inconceivably more intelligent than yourself?...to be a molecule, a microbe, a mosquito, an ant, or an ant colony? (Hofstadter and Dennett, (1981: 404-5), pose many more such provocative questions.) In other words, what is it like from the inside? Now, imagine being a bat. A bat's experience must be very different from that of a human. For a start the bat's sensory systems are quite different, which is why Nagel chose the bat for his famous question. Bats' brains, lives and sensesare well understood (Akins, 1993; Dawkins, 1986). Most use either sound or ultrasound for echolocation. That is, they detect objects by emitting rapid high-pitched clicks that bounce off any objects in the vicinity and then measuring the time taken for the echo to return. Natural selection has found ingenious solutions to the many interesting problems posed by echolocation. Some bats cruise around emitting clicks quite slowly so as not to waste energy, but then when they are homing in on prey or approaching a potential danger, they speed up. Many have mechanisms that protect their ears from the loud blastof each click and then open them to receive the faint echo. Some use the Doppler shift to work out their speed relative to prey or other objects. Others sort out the mixed-up echoes from different objects by emitting downward-swooping sounds. The echoes from distant objects take longer to come back and therefore sound higher than the echoes from nearer objects. In this way we can imagine that a whole bat world is built up in which higher sounds mean distant objects and lower sounds mean nearer objects. What would this be like? According to Oxford biologist Richard Dawkins (1986; see Profile, Chapter 10), it might be like seeing is for us. We humans do not know, or care, that colour is related to wavelength or that motion detection is carried out in the visual cortex. We just see the objects out there in depth and colour. Similarly the bat would just perceive the objects out there in depth, and perhaps even in some batty, sonar, version of colour. Living in this constructed world would be what it is like to be the bat. But can we ever know what it would really be like for the bat? As Nagel pointed out, the question is not answered by trying to imagine that you are a bat. This will not do. It is no good hanging upside down in a darkened room, making little clicks with your tongue and flapping your arms like wings. Perhaps if you could magically be transformed into a bat you would know. But even this won't do. For if you were a bat, the bat in question would notbe an ordinary bat - what with having your memories and your interest inconsciousness. But if you became an ordinary bat then this bat would have no understanding of English, no ability to ask questions about consciousness, and could not tell us what it was like. So we cannot know what it is like to be a bat even if we believe that there is something it is like to be a bat. Nagel's question clarifies the central meaning of the term 'consciousness'. It is what the American philosopher Ned Block (1995) calls 'phenomenal consciousness' or phenomenality. He explains that 'Phenomenal consciousness isexperience; what makes a state phenomenally conscious is that there is something 'it is like' to be in that state.' He distinguishes this from 'access consciousness', which is 'availability for use in reasoning and rationally guiding speech and action' (Block, 1995: 227). We will return to this distinction (Chapter 18), and consider issues to do with availability, but 'phenomenal consciousness' is what this book is all about. So what is it like to be you now? Everything I have said so far implies that there is, uncontroversially, something it is like to be you now - that the problems only begin when you start asking about what it is like to be someone orsomething else. But is this right? A thoroughly sceptical approach would meanquestioning even this. I urge you to do this chapter's 'Practice' and become a little more familiar with what it is like to be you.

Added by: Clotilde Torregrossa, Contributed by: Juan R. LoaizaAbstract: This paper explores the relationship between several ideas about the mind and cognition. The hypothesis of extended cognition claims that cognitive processes can and do extend outside the head, that elements of the world around us can actually become parts of our cognitive systems. It has recently been suggested that the hypothesis of extended cognition is entailed by one of the foremost philosophical positions on the nature of the mind: functionalism, the thesis that mental states are defined by their functional relations rather than by their physical constituents. Furthermore, it has been claimed that functionalism entails a version of extended cognition which is sufficiently radical as to be obviously false. I survey the debate and propose several ways of avoiding this conclusion, emphasizing the importance of distinguishing the hypothesis of extended cognition from the related notion of the extended mind.
Comment: This text provides a helpful overview of the thesis of the extended mind and its relation to functionalism. It can be used as a central reading in an intermediate or advanced undergraduate course on philosophy of mind.

Abstract: The content of the externalist thesis about the mind depends crucially on how we define the distinction between the internal and the external. According to the usual understanding, the boundary between the internal and the external is the skull or the skin of the subject. In this paper I argue that the usual understanding is inadequate, and that only the new understanding of the external/internal distinction I suggest helps us to understand the issue of the compatibility of externalism and privileged access

Added by: Clotilde Torregrossa, Contributed by: Simon FoktPublisher's Note: Charles Siewert offers a persuasive argument to show that the presence of certain phenomenal features logically suffices for the presence of certain intentional ones. He claims that this shows that phenomenal features are inherently intentional. I argue that he has not established the latter thesis, even if we grant the logical sufficiency claim. For he has not ruled out a rival alternative interpretation of the relevant data, namely, that intentional features are inherently phenomenal

Added by: Nick NovelliAbstract: I defend the view that we should not overintellectualize the mind. Nonhuman animals can occupy islands of practical rationality: they can have contextbound reasons for action even though they lack full conceptual abilities. Holism and the possibility of mistake are required for such reasons to be the agent's reasons, but these requirements can be met in the absence of inferential promiscuity. Empirical work with animals is used to illustrate the possibility that reasons for action could be bound to symbolic or social contexts, and connections are made to simulationist accounts of cognitive skills.
Comment: An excellent argument in favour of a less-intellectual criteria for reason-having. The arguments are clear and compelling, though at least some familiarity with action theory would be helpful to give proper context. Recommended for higher-level or more in-depth examinations of reasons, as its relevance is partly dependent on some of the other arguments made on the subject.

Added by: Nick NovelliPublisher's Note: In this important book, Susan Hurley sheds new light on consciousness by examining its relationships to action from various angles. She assesses the role of agency in the unity of a conscious perspective, and argues that perception and action are more deeply interdependent than we usually assume. A standard view conceives perception as input from world to mind and action as output from mind to world, with the serious business of thought in between. Hurley criticizes this picture, and considers how the interdependence of perceptual experience and agency at the personal level (of mental contents and norms) may emerge from the subpersonal level (of underlying causal processes and complex dynamic feedback systems). Her two-level view has wide implications, for topics that include self-consciousness, the modularity of mind, and the relations of mind to world. The self no longer lurks hidden somewhere between perceptual input and behavioral output, but reappears out in the open, embodied and embedded in its environment. Hurley traces these themes from Kantian and Wittgensteinian arguments through to intriguing recent work in neuropsychology and in dynamic systems approaches to the mind, providing a bridge from mainstream philosophy to work in other disciplines. Consciousness in Action is unique in the range of philosophical and scientific work it draws on, and in the deep criticism it offers of centuries-old habits of thought.
Comment: This book provides an interesting challenge to some standard assumptions about consciousness, action, and perception. The chapters are relatively self-contained, and can be read separately. The appendix of argument outlines is helpful as an aid to comprehension, and could serve as a valuable teaching tool in its own right.

Added by: Nick NovelliPublisher's Note: The philosophy of mind has long been part of the core philosophy curriculum, and this book is the classic, comprehensive survey of the subject. Designed as an introduction to the field for upper-level undergraduates and graduate students, Philosophy of Mind focuses on the mind-body problem and related issues, some touching on the status of psychology and cognitive science. The third edition has been thoroughly updated throughout to reflect developments of the past decade, and it is the only text of its kind that provides a serious and respectful treatment of substance dualism. This edition also includes two new chapters on the nature of consciousness and the status of consciousness. Improved readability and clarity has been one important aim of the new edition. Throughout the text, author Jaegwon Kim allows readers to come to their own terms with the central problems of the mind. At the same time, Kim's own emerging views are on display and serve to move the discussion forward. Comprehensive, clear, and fair, Philosophy of Mind is a model of philosophical exposition and a significant contribution to the field.
Comment: An excellent textbook for an undergraduate introductory course on philosophy of mind, it offers a good overview of issues such as the mind/body problem, consciousness, and dualism.

Added by: Nick NovelliPublisher's Note: Contemporary discussions in philosophy of mind have largely been shaped by physicalism, the doctrine that all phenomena are ultimately physical. Here, Jaegwon Kim presents the most comprehensive and systematic presentation yet of his influential ideas on the mind-body problem. He seeks to determine, after half a century of debate: What kind of (or "how much") physicalism can we lay claim to? He begins by laying out mental causation and consciousness as the two principal challenges to contemporary physicalism. How can minds exercise their causal powers in a physical world? Is a physicalist account of consciousness possible? The book's starting point is the "supervenience" argument (sometimes called the "exclusion" argument), which Kim reformulates in an extended defense. This argument shows that the contemporary physicalist faces a stark choice between reductionism (the idea that mental phenomena are physically reducible) and epiphenomenalism (the view that mental phenomena are causally impotent). Along the way, Kim presents a novel argument showing that Cartesian substance dualism offers no help with mental causation. Mind-body reduction, therefore, is required to save mental causation. But are minds physically reducible? Kim argues that all but one type of mental phenomena are reducible, including intentional mental phenomena, such as beliefs and desires. The apparent exceptions are the intrinsic, felt qualities of conscious experiences ("qualia"). Kim argues, however, that certain relational properties of qualia, in particular their similarities and differences, are behaviorally manifest and hence in principle reducible, and that it is these relational properties of qualia that are central to their cognitive roles. The causal efficacy of qualia, therefore, is not entirely lost. According to Kim, then, while physicalism is not the whole truth, it is the truth near enough.
Comment: A great book on the mind-body problem. In addition to presenting Kim's own view, it does an excellent job explaining the problem, as well as presenting some of the opposing viewpoints clearly and strongly, before providing good objections. Many sections would be useful as part of an examination of the mind-body problem in general.

Added by: Nick NovelliAbstract: The puzzle of imaginative desire arises from the difficulty of accounting for the surprising behaviour of desire in imaginative activities such as our engagement with fiction and our games of pretend. Several philosophers have recently attempted to solve this puzzle by introducing a class of novel mental states - what they call desire-like imaginings or i-desires. In this paper, I argue that we should reject the i-desire solution to the puzzle of imaginative desire. The introduction of i-desires is both ontologically profligate and unnecessary, and, most importantly, fails to make sense of what we are doing in the imaginative contexts in question.
Comment: Kind provides good arguments against accepting the existence of "i-desires". This article would be useful to teach in the context of philosophy of mind, as well as in philosophy of art and fiction, as it engages with some of the issues surrounding "make-believe".

Added by: Nick NovelliAbstract: Philosophers and psychologists have often maintained that in order to attribute mental states to other people one must have a 'theory of mind'. This theory facilitates our grasp of other people's mental states. Debate has then focussed on the form this theory should take. Recently a new approach has been suggested, which I call the 'Direct Perception approach to social cognition'. This approach maintains that we can directly perceive other people's mental states. It opposes traditional views on two counts: by claiming that mental states are observable and by claiming that we can attribute them to others without the need for a theory of mind. This paper argues that there are two readings of the direct perception claims: a strong and a weak one. The Theory-theory is compatible with the weak version but not the strong one. The paper argues that the strong version of direct perception is untenable, drawing on evidence from the mirror neuron literature and arguments from the philosophy of science and perception to support this claim. It suggests that one traditional 'theory of mind' view, the 'Theory-theory' view, is compatible with the claim that mental states are observable, and concludes that direct perception views do not offer a viable alternative to theory of mind approaches to social cognition.
Comment: A good argument against direct perception as an alternative to theory theory. Since the direct perception theory is somewhat trendy, this paper would be a useful counterpoint in philosophy of mind courses.

Added by: Clotilde Torregrossa, Contributed by: Simon FoktAbstract: It seems that a solution to the body problem, or at least one that helps us to better understand the mind-body problem, is not forthcoming. And I take it this indicates that, at least for the time being, we should focus on questions other than the question 'Is the mind physical?' To this end, I would like to suggest a question that, I think, highlights some of the central concerns of both physicalists and dualists. And this is the question of whether the mental is fundamentally non-mental. For it seems that physicalism is, at least in part, motivated by the belief that the mental is ultimately non-mental, that is, that mental properties are not fundamental properties, while a central tenet of dualism, precisely, that they are. Of course the notion of the non-mental is also open ended. And, for this reason, it may be just as difficult to see, what sort of considerations are relevant in determining what counts as non-mental as it is to see what sort of considerations could be relevant in determining what counts as physical. But, of course, this is a project for another paper. One advantage, however, is that, arguably, we do have a grasp of one side of the divide - that is, the mental side. So, perhaps, rather than worrying about whether the mind is fundamentally physical, we should be concerned with whether the mind is fundamentally non-mental. And this, I should mention, is a concern that has little to do with what current physics, future physics, or a final physics says about the world.

Added by: Emily Paul, Contributed by: Greg MillerAbstract: This article discusses recent disagreements over the correct formulation of physicalism. Although there appears to be a consensus outside those who discuss the issue that physicalists believe that what exists is what is countenanced by physics, as we will see, this orthodoxy faces an important puzzle now frequently referred to as 'Hempel's Dilemma'. After surveying the historical trajectory from Enlightenment-era materialism to contemporary physicalism, I examine several mainstream approaches that respond to Hempel's dilemma, and the benefits and drawbacks of each.
Comment: A great paper for an intermediate or advanced metaphysics course that provides a clear and accessible overview of physicalism and its history, but also more detailed discussion around the topic. It canvasses contemporary formulations of physicalism and their problems. This text is helpful for students in supplying them with a strong overview of the debate. Set seminar questions could (for example) ask students to outline Hempel's dilemma, and their preferred response to this dilemma that is discussed by Ney.

Added by: Clotilde Torregrossa, Contributed by: Nora HeinzelmannIntroduction: Everyone familiar with the current mind-body debate has probably heard about Frank Jackson's neurophysiologist Mary. So I tell her story very briefly. Mary knows everything there is to know about the neurophysiological basis of human colour vision but she never saw colours herself (she always lived in a black-and-white environment). When Mary is finally released into the beauty of the coloured world, she acquires new knowledge about the world and - more specifically - about the character of the visual experiences of others. This appears clear at first sight. In the ongoing philosophical debate, however, there is no agreement about whether Mary really gains new knowledge and about whether this would, if it were so, represent a problem for physicalism. Those who defend the so-called argument from knowledge (or 'knowledge argument') think that it does.

Added by: Francesca BrunoAbstract: In general outline, Astell’s A Serious Proposal to the Ladies is well understood. In Part I, Astell argues that women are educable, and she proposes the construction of a women’s academy. In Part II, she proposes a method for the improvement of the mind. In this article, I reconstruct and contextualize Astell’s arguments and proposals within her theory of mind and her account of the skeptical predicament that she sees as being endemic among women. I argue that Astell’s two proposals are best understood as strategies that, when employed, will allow women to critique prejudice and custom.
Comment: This is a very accessible article and would be a good secondary source to assign for an introductory course reading Astell's work, ‘A Serious Proposal to the Ladies.’

Comment: One of the better arguments against multiple realizability. Could be used in any philosophy of mind course where that claim arises as a demonstration of how it could be challenged. A good deal of discussion about neuroscientific practices and methods, but not excessively technical.
