A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts are importantly (...) different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience. (shrink)

According to Frank Jackson’s famous knowledge argument, Mary, a brilliant neuroscientist raised in a black and white room and bestowed with complete physical knowledge, cannot know certain truths about phenomenal experience. This claim about knowledge, in turn, implies that physicalism is false. I argue that the knowledge argument founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been (...) removed, Mary can know the relevant truths. If we give Mary the epistemological capabilities necessary to draw metaphysical conclusions about physicalism, she will, while trapped in the black and white room, be able to know every truth about phenomenal experience.

Current attempts to understand psychological content divide into two families of views. According to externalist accounts such as those advanced by Tyler Burge and Ruth Millikan, psychological content does not supervene on the physical features of the individual subject, but is fixed partially by the nature of the world external to her.¹ In the rival functional role theories developed by Ned Block and Brian Loar, content does supervene on the physical features of the individual, and is, in addition, determined solely (...) by the role it plays in the causal network of an individual's sensations, behavior, and mental states.² Over the past fifteen years, criticism of these two types of views has often focussed on their capacity to individuate content in an acceptable way, and both seem to be deficient in this respect.

This article presents the knowledge argument against physicalism and objections to it. The focus is on the ways responses to that argument have tried to account for phenomenal knowledge within a physicalist picture. Various ‘phenomenal concepts’ strategies are considered, along with recent arguments against them. Also considered are attempts to explain phenomenal knowledge in terms of indexical knowledge and in terms of acquaintance.

Is conceptual analysis required for reductive explanation? If there is no a priori entailment from microphysical truths to phenomenal truths, does reductive explanation of the phenomenal fail? We say yes . Ned Block and Robert Stalnaker say no.

In chapter 1 of Reason, Truth, and History, Hilary Putnam argues from some plausible assumptions about the nature of reference to the conclusion that it is not possible that all sentient creatures are brains in a vat. If this argument is successful, it seemingly refutes an updated form of Cartesian skepticism concerning knowledge of physical objects. In this paper, I will state what I take to be the most promising interpretation of Putnam's argument. My reconstructed argument differs from an argument (...) strongly suggested by Putnam's text. I will show that the latter argument obviously does not work. The more promising argument which I reconstruct on behalf of Putnam raises some interesting questions about the relation between the contents of one's beliefs and one's environment and about how this relation affects the evaluation of anti-skeptical arguments. I conclude that my reconstructed argument ultimately fails as a response to Cartesian skepticism: the argument engenders a skepticism about knowledge of meaning, or propositional content, which undercuts its anti-skeptical force.

It has long been widely agreed that some concepts can be possessed only by those who have undergone a certain type of phenomenal experience. Orthodoxy among contemporary philosophers of mind has it that these phenomenal concepts provide the key to understanding many disputes between physicalists and their opponents, and in particular offer an explanation of Mary’s predicament in the situation exploited by Frank Jackson's knowledge argument. I reject the orthodox view; I deny that there are phenomenal concepts. My arguments exploit (...) the sort of considerations that are typically used to motivate externalism about mental content. Although physicalists often appeal to phenomenal concepts to defend their view against the knowledge argument, I argue that this is a mistake. The knowledge argument depends on phenomenal concepts; if there are no phenomenal concepts, then the knowledge argument fails. (shrink)

Mary learns all the physical facts that one can learn by watching lectures on black-on-white television. According to Jackson, Mary learns new facts when she leaves the room and has color experiences, and that this undermines physicalism. Physicalists have responded by denying the new facts thesis; they argue, she acquires abilities, acquaintance knowledge, or new guises. I argue that the NFT is more plausible than any of the proposed alternatives. I also argue that the NFT does not undermine physicalism unless (...) physicalism entails that all physical facts are discursively learnable, and that the latter entailment is questionable. (shrink)

Oxford Studies in Metaphysics is the forum for the best new work in this flourishing field. Much of the most interesting work in philosophy today is metaphysical in character: this new series is a much-needed focus for it. OSM offers a broad view of the subject, featuring not only the traditionally central topics such as existence, identity, modality, time, and causation, but also the rich clusters of metaphysical questions in neighbouring fields, such as philosophy of mind and philosophy of science. (...) Besides independent essays, volumes will often contain a critical essay on a recent book, or a symposium that allows participants to respond to one another's criticisms and questions. Anyone who wants to know what's happening in metaphysics can start here. Volume Two begins with a major paper on consciousness by Ned Block. Block examines 'Max Black's Objection to Mind-Body Identity', an argument for a dualism of physical and phenomenal properties, closely related to Jackson's 'knowledge argument'. His extensive exploration of this family of arguments for property dualism includes considerable discussion of John Perry and Stephen White; their responses to Block's paper complete the section on the metaphysics of consciousness.Three papers consider the thesis that the future is, in some sense, 'open'. Eli Hirsch elaborates a view according to which contingent statements about the future can be indeterminate in truth-value, while preserving 'straight logic', including a principle of bivalence. Peter Forrest defends a sort of 'growing block' theory of the passage of time, emphasizing the way such a metaphysics, combined with a truth-maker principle, can provide an analysis of natural necessity. Trenton Merricks presents a trenchant and original criticism of the 'growing block' theory of time.The volume continues with a group of papers on problems of ontology. Thomas Hofweber's paper, defending nominalism from the objection that there are 'inexpressible' properties and propositions, won the first annual Oxford Studies in Metaphysics Younger Scholar Prize. The papers by Phillip Bricker and Michael Loux examine a couple of deep divides within ontology. John Hawthorne's paper raises some extremely puzzling questions about the nature of persons, given the ontology needed for Timothy Williamson's theory of vagueness. Hawthorne uses these problems to motivate an alternative style of epistemicism. The final three papers take up several issues in the metaphysics of traditional theism. Michael Bergmann and Jeffrey Brower raise objections to combining a Platonic conception of universals with the doctrine of divine aseity; while Brian Leftow defends a non-Platonic theory of universals - a kind of divine-concept nominalism. Hud Hudson suggests that contemplation of the possibility of higher dimensions opens up new avenues in theodicy. (shrink)

The relation between subjective consciousness and the physical brain is widely regarded as the last mystery facing science. David Papineau argues that there is no real puzzle here. Consciousness seems mysterious, not because of any hidden essence, but only because we think about it in a special way. Papineau exposes the confusion, and dispels the mystery: we see consciousness in its place in the material world, and we are on the way to a proper understanding of the mind.

Contemporary Materialism brings together the best recent work on materialism from many of our leading contemporary philosophers. This is the first comprehensive reader on the subject. The majority of philosophers and scientists today hold the view that all phenomena are physical, as a result materialism or 'physicalism' is now the dominant ontology in a wide range of fields. Surprisingly no single book, until now, has collected the key investigations into materialism, to reflect the impact it has had on current thinking (...) in metaphysics, philosophy of mind and the theory of value. The classic papers in this collection chart contemporary problems, positions and themes in materialism. At the invitation of the editors, many of the papers have been specially up-dated for this collection: follow-on pieces written by the contributors enable them to appraise the original paper and assess developments since the work was first published. The book's selections are largely non-technical and accessible to advanced undergraduates. The editors have provided a useful general introduction, outlining and contextualising this central system of thought, as well as a topical bibliography. Contemporary Materialism will be vital reading for anyone concerned to discover the ideas underlying contemporary philosophy.

The contributions to this book are original articles, representing a cross-section of current philosophical work on consciousness and thereby allowing students and readers from other disciplines to acquaint themselves with the very latest debate, so that they can then pursue their own research interests more effectively. The volume includes a bibliography on consciousness in philosophy, cognitive science and brain research, covering the last 25 years and consisting of over 1000 entries in 18 thematic sections, compiled by David Chalmers and Thomas (...) Metzinger. (shrink)

The arguments presented in this comprehensive collection have important implications for the philosophy of mind and the study of consciousness.

By definition zombies would be physically and behaviourally just like us, but not conscious. This currently very influential idea is a threat to all forms of physicalism, and has led some philosophers to give up physicalism and become dualists. It has also beguiled many physicalists, who feel forced to defend increasingly convoluted explanations of why the conceivability of zombies is compatible with their impossibility. Robert Kirk argues that the zombie idea depends on an incoherent view of the nature of phenomenal (...) consciousness. His book has two main aims. One is to demolish the zombie idea once and for all. There are plenty of objections to it in the literature, but they lack intuitive appeal. He offers a striking new argument which reveals fundamental confusions in the implied conception of consciousness. The book's other main contribution is to develop a fresh and original approach to the true nature of phenomenal consciousness. Kirk argues that a necessary condition is a 'basic package' of capacities. An important component of his argument is that the necessary cognitive capacities are not as sophisticated as is often assumed. By focusing on humbler creatures than ourselves he avoids some of the distracting complications of our sophisticated forms of cognition. The basic package does not seem to be sufficient for phenomenal consciousness. What is also needed is 'direct activity' - a special feature of the way the events which constitute incoming perceptual information affect the system. This is an integrated process, to be conceived of holistically, and contrasts sharply with what is often called the 'availability' or 'poisedness' of perceptual information. This original, penetrating, and readable book will be of interest to all who have a serious concern with the nature of consciousness: not only professional philosophers and students, but psychologists and neuroscientists.

A number of popular arguments for dualism start from a premise about an epistemic gap between physical truths about truths about consciousness, and infer an ontological gap between physical processes and consciousness. Arguments of this sort include the conceivability argument, the knowledge argument, the explanatory-gap argument, and the property dualism argument. Such arguments are often resisted on the grounds that epistemic premises do not entail ontological conclusion. My view is that one can legitimately infer ontological conclusions from epistemic premises, if (...) one is very careful about how one reasons. To do so, the best way is to reason first from epistemic premises to modal conclusions , and from there to ontological conclusions. Here, the crucial issue is the link between the epistemic and modal domains. How can one reason from theses about what is knowable or conceivable to theses about what is necessary or possible? To bridge the epistemic and modal domains, the framework of two-dimensional semantics can play a central role. I have used this framework in earlier work to mount an argument against materialism. Here, I want to revisit the argument, laying it out in a more explicit and careful form, and responding to a number of objections. In what follows I will concentrate mostly on the conceivability argument. I think that very similar considerations apply to the other arguments mentioned above, however. In the final section of the paper, I show how this analysis might yield a unified treatment of a number of anti-materialist arguments. (shrink)

In this speculative paper I would like to show how important the integration of mental content is for a theory of phenomenal consciousness. I will draw the reader's attention to two manifestations of this problem which already play a role in the empirical sciences concerned with consciousness: The binding problem and the superposition problem. In doing so I hope to be able to leave the welltrodden paths of the debate over consciousness. My main concern is to gain a fresh access (...) to the familiar theoretical difficulties associated with the concept of 'consciousness'. (shrink)
