I argue that zombies are inconceivable. More precisely, I argue that the conceivability-intuition that is used to demonstrate their possibility has been misconstrued. Thought experiments alleged to feature zombies founder on the fact that, on the one hand, they _must_ involve first-person imagining, and yet, on the other hand, _cannot_. Philosophers who take themselves to have imagined zombies have unwittingly conflated imagining a creature who lacks consciousness with imagining a creature without also imagining the consciousness it may or may not (...) possess.

Recent work on signaling has mostly focused on communication between organisms. The Lewis–Skyrms framework should be equally applicable to intra-organismic signaling. We present a Lewis–Skyrms signaling-game model of painful signaling, and use it to argue that the content of pain is predominantly imperative. We address several objections to the account, concluding that our model gives a productive framework within which to consider internal signaling.

The central fact about the problem of personal identity is that it is a problem posed by an apparent dichotomy: the dichotomy between the objective, third-person viewpoint on the one hand and the subjective perspective provided by the first-person viewpoint on the other. Everyone understands that the mind/body problem is precisely the problem of what to do about another apparent dichotomy, the duality comprising states of consciousness on the one hand and physical states of the body on the other. By (...) contrast, contemporary discussions of the problem of personal identity generally display little or no recognition of the divide which to my mind is at the heart of the problem. As a consequence, there has been a relentlessly third-personal approach to the issue, and the consequent proposal of solutions which stand no chance at all of working. I think the idea that the problem is to be clarified by an appeal to the idea of a human being is the latest manifestation of this mistaken approach. I am thinking in particular of the claim that what ought to govern our thinking on this issue is the fact that human beings constitute a natural kind, and that standard members of this kind can be said to have some sort of essence. Related to this is the idea that ‘person’, while not itself a natural kind term, is not a notion which can be framed in entire independence of this natural kind. (shrink)

It is widely accepted that physicalism faces its most serious challenge when it comes to making room for the phenomenal character of psychological experience, its so-called what-it-is-like aspect. The challenge has surfaced repeatedly over the past two decades in a variety of forms. In a particularly striking one, Frank Jackson considers a situation in which Mary, a brilliant scientist who knows all the physical facts there are to know about psychological experience, has spent the whole of her life in a (...) black and white room. He asks, What will happen when Mary is released from her black and white room or is given a colour television monitor? Will she learn anything or not? It seems just obvious that she will learn something about the world and our visual experience of it. But then it is inescapable that her previous knowledge was incomplete. But she had all the physical information. (Jackson 1986: 130). (shrink)

My primary aim in this chapter is to explain in what the traditional mind–body problem consists, what its possible solutions are, and what obstacles lie in the way of a resolution. The discussion will develop in two phases. The first phase, sections 1.2–1.4, will be concerned to get clearer about the import of our initial question as a precondition of developing an account of possible responses to it. The second phase, sections 1.5–1.6, explains how a problem arises in our attempts (...) to answer the question we have characterized, and surveys the various solutions that can be and have been offered. More specifically, sections 1.2–1.4 are concerned with how to understand the basic elements of our initial question – how we should identify the mental, on the one hand, and the physical, on the other – and with what sorts of relations between them we are concerned. Section 1.2 identifies and explains the two traditional marks of the mental, consciousness and intentionality, and discusses how they are related. Section 1.3 gives an account of how we should understand ‘physical’ in our initial question so as not to foreclose any of the traditional positions on the mind–body problem. Section 1.4 then addresses the third element in our initial question, mapping out the basic sorts of relations that may hold between mental and physical phenomena, and identifying some for special attention. Sections 1.5–1.6 are concerned with explaining the source of the difficulty in answering our initial question, and the kinds of solutions that have been offered to it. Section 1.5 explains why our initial question gives rise to a problem, and gives a precise form to the mind–body problem, which is presented as a set of four propositions, each of which, when presented independently, seems compelling, but which are jointly inconsistent. Section 1.6 classifies responses to the mind–body problem on the basis of which of the propositions in our inconsistent set they reject, and provides a brief overview of the main varieties in each category, together with some of the difficulties that arise for each. Section 1.7 is a brief conclusion about the source of our difficulties in understanding the place of mind in the natural world. (shrink)

Drawing on data from contemporary experimental psychology and research in artificial intelligence, Dennett argues for a multiple drafts model of human consciousness, which he offers as an alternative to what he calls Cartesian materialism. I argue that the considerations Dennett advances do not, in fact, call for the abandonment of Cartesian materialism. Moreover, the theory presented by Dennett does not, as he claims, succeed in explaining consciousness; in particular, it fails to do justice to qualia. Illuminating though Dennett's discussion is, (...) in many ways, it nevertheless leaves the traditional mind?body problem intact. (shrink)

This paper considers the so-called explanatory gap between brain activity and conscious experience. A number of different, though closely related, explanatory gaps are distinguished and a monistic account of conscious experience, a version of Herbert Feigl’s “twofold-access theory,” is advocated as a solution to the problems they are taken to pose for physicalist accounts of mind. Although twofold-access theory is a version of the mind-body identity thesis, it in no way “eliminates” conscious experience; rather, it provides a parsimonious and explanatorily (...) fruitful theory of the consciousness-body relation which faithfully preserves the nature of conscious experience while going quite far in “bridging” the various explanatory gaps distinguished below.

This paper argues, not that physicalism is wrong, but that it is irrational. The paper defines standards of rationality, both metaphysical and epistemological, that physicalism necessarily inherits from science. Then it assesses physicalist efforts to naturalize consciousness in light of these. It concludes that physicalism allows its metaphysics to outrun its epistemology, in defiance of applicable standards, revealing a fundamental incoherence in the doctrine. The paper also briefly reviews other naturalization programs, to claim that physicalism, unlike the sciences, hasn’t proved (...) fruitful. (shrink)

Most definitions of radical emergentism characterize it epistemologically. This leads to misunderstandings and makes it hard to assess the doctrine's metaphysical worth. This paper puts forward purely metaphysical characterizations of emergentism and property emergence. It explores the nature of the necessitation relation between base and emergent and argues that emergentism entails a Humean account of causation and related relations. Then it presents arguments against emergentism, both as a wider metaphysic and as an account of consciousness. These maintain that emergentism makes (...) implausible claims about how the world works. The paper also stresses the doctrine's contemporary relevance: most current property dualists endorse views effectively identical to classical emergentism less its historical commitment to novel emergent forces.

In a footnote to his ‘What is it Like to be a Bat?’, Thomas Nagel sketches a promising account of phenomenal concepts that purports to explain why mind-body identity statements, even if necessary, will always seem contingent. Christopher Hill and Brian McLaughlin have recently developed this sketch into a more robust theory. In Nagel's more recent work, however, he suggests that the only adequate theory of phenomenal concepts is one that makes the relation between phenomenal and physical states intelligible, or (...) ‘transparent’. Developing such a theory, however, appears to be no easy task. In this paper I argue that the Nagel-Hill-McLaughlin proposal is preferable – and that a serious problem with it, noticed by Stephen Yablo, can be avoided by revising the proposal according to some further suggestions made by Nagel himself.

In traditional armchair methodology, philosophers attempt to challenge a thesis of the form ‘F iff G’ or ‘F only if G’ by describing a scenario that elicits the intuition that what has been described is an F that isn’t G. If they succeed, then the judgment that there is, or could be, an F that is not G counts as good prima facie evidence against the target thesis. Moreover, if these intuitions remain compelling after further (good faith) reflection, then traditional (...) armchair methodology takes the judgment to be serious (though not infallible) evidence against the target thesis—call it secunda facie evidence—that should not be discounted as long as those intuitions retain their force. Some philosophers, however, suggest that this methodology is incompatible with epistemological naturalism, the view that philosophical inquiry should be sensitive to empirical observations, and argue that traditional armchair methodology must deemphasize the role of intuitions in philosophical inquiry. In my view, however, this would be a mistake: as I will argue, the most effective way to promote philosophical progress is to treat intuitions as having the (prima and secunda) evidential status I’ve described. But I will also argue that philosophical inquiry can produce a theory that is sensitive to empirical observations and the growth of empirical knowledge, even if it gives intuitions the prima- and secunda-facie evidential status that traditional armchair methodology demands—and thus that traditional armchair methodology, if properly practiced, need not be abandoned by naturalists, or even (except for a few exceptions) be much revised.

In this response to David Bradnick's and Bradford McCall's defense of Amos Yong's usage of emergence theory, we defend our previous argument regarding the tension between Yong's Pentecostal commitments and the philosophical entailments of emergence theory. We clarify and extend our previous concerns in three ways. First, we explore the difficulties of construing divine action naturalistically. Second, we clarify the problems of employing supervenience in theology. Third, we show why Bradnick's and McCall's advice to Yong to adopt weak emergence is (...) theologically costly. In conclusion, it is suggested that theologians within the science and religion dialogue should not fear, but recover, the language of supernaturalism and dualism. (shrink)

This article critically analyzes Owen Flanagan's physicalism and attempt at deriving ethical normativity from current neuroscience. It is argued that neurophysicalism, despite Flanagan's harsh critique of “the new mysterians,” entails a form of mysterianism and that it fails to appropriately ground human mentality within physicalism. Flanagan seeks to bring spirituality and a physicalist ontology together by showing how it is possible to derive an account of the good life from science. This attempt is critiqued and it is shown that Flanagan (...) fails to establish the consistency between ethical normativity and physicalism. Hence, another form of mysterianism seems to emerge within this normative mind science. (shrink)

In Chinese body culture, the construct of qi 氣—literally translated as breath or energy—is at the heart of several programs of self‐cultivation, as well as other domains of bodily knowledge related to the subjective and inter‐subjective realm of everyday life. Also, among Chinese societies and communities, discourses on qi have assumed social significance in the milieus of politics, religion, and popular culture. Therefore, it appears to be the case that a concern for the qi experience is significant to both the (...) Chinese sensorium and its sociocultural context. However, while this category is ubiquitous, we are still left with the question of how people learn, elaborate, and make sense of it. By drawing from an in‐depth ethnographic study of a group of neidan qigong 內丹氣功 practitioners in Taipei, Taiwan, the aim of this article is twofold. To a greater extent, it investigates what role qigong, a mind‐body practice to cultivate and balance the vital energy, plays in the individual learning, elaboration, and understanding of the qi sensory experience. To a lesser extent, it considers this case study in the broader sociocultural context, in order to demonstrate that a first‐person approach to the qi experience can contribute to understanding the dynamics between embodied learning, consciousness, and society.

McGinn claims that there is nothing “inherently mysterious” about consciousness, even though we will never be able to understand it. The first claim is no more than a rhetorical flourish. The second may be read either as a claim that we are unable to construct an explanatory theory of consciousness, or that any such theory must strike us as unintelligible, in the sense in which quantum mechanics is sometimes said to be unintelligible. On the first reading, McGinn's argument is based (...) on a false premiss . On the second reading, it suffers from the shortcoming that the central notion of intelligibility is too obscure to permit any definite conclusion. I close with a brief discussion of the contemporary tendency to reject non-physicalist approaches to consciousness on a priori grounds. (shrink)

The paper discusses Colin McGinn’s mysterianist approach to the phenomenon of consciousness. According to McGinn, consciousness is, in and of itself, a fully natural phenomenon, but we humans are just cognitively closed to it, meaning that we cannot in principle understand its nature. I argue that, on a proper conception of the relation between an intellectual problem and its solution, we may well not know what the solution is to a problem we understand, or we may not understand exactly what (...) the problem is, but it is incoherent to suppose that we cannot understand what would count as a solution to a problem we can and do understand. The argument appeals to certain accepted assumption in the logic of questions, developed in the early sixties, mainly by Stahl. I close with a general characterization of mysterianism as such, and formulate a form of mysterianism which is in some sense more optimistic and in another more pessimistic than McGinn’s. (shrink)

. When I have a conscious experience of the sky, there is a bluish way it is like for me to have that experience. We may distinguish two aspects of this "bluish way it is like for me": the bluish aspect and the for-me aspect. Let us call the bluish aspect of the experience its qualitative character and the for-me aspect its subjective character . What is this elusive for-me-ness, or subjective character , of conscious experience? In this paper, I (...) examine six different attempts to account for subjective character in terms of the functional and representational properties of conscious experiences. After arguing against the first five, I defend the sixth. (shrink)

It is often assumed thatconsciousness and intentionality are twomutually independent aspects of mental life.When the assumption is denounced, it usuallygives way to the claim that consciousness issomehow dependent upon intentionality. Thepossibility that intentionality may bedependent upon consciousness is rarelyentertained. Recently, however, John Searle andColin McGinn have argued for just suchdependence. In this paper, I reconstruct andevaluate their argumentation. I am in sympathyboth with their view and with the lines ofargument they employ in its defense. UnlikeSearle and McGinn, however, I am (...) quite attachedto a naturalist approach to intentionality. Itwill turn out to be somewhat difficult toreconcile naturalism with the notion thatintentionality is dependent upon consciousness,although, perhaps surprisingly, I will arguethat McGinn's case for such dependence iscompatible with naturalism.

Illusionism about phenomenal consciousness is the thesis that phenomenal consciousness does not exist, even though it seems to exist. This thesis is widely judged to be uniquely counterintuitive: the idea that consciousness is an illusion strikes most people as absurd, and seems almost impossible to contemplate in earnest. Defenders of illusionism should be able to explain the apparent absurdity of their own thesis, within their own framework. However, this is no trivial task: arguably, none of the illusionist theories currently on (...) the market is able to do this. I present a new theory of phenomenal introspection and argue that it might deal with the task at hand. (shrink)

Many philosophers have tried to defend physicalism concerning phenomenal consciousness, by explaining dualist intuitions within a purely physicalist framework. One of the most common strategies to do so consists in interpreting the alleged “explanatory gap” between phenomenal states and physical states as resulting from a fallacy, or a cognitive illusion. In this paper, I argue that the explanatory gap does not rest on a fallacy or a cognitive illusion. This does not imply the falsity of physicalism, but it has consequences (...) on the kind of physicalism we should embrace. (shrink)

This article addresses two issues: the distinction between objective and subjective measures and the directness of such measures. It is argued that the distinction is unambiguous only when based on a methodological criterion rather than a semantic one. Different senses of directness are discussed: metaphysical, methodological, semantic, and causal.

In a recent Zygon article (June 1991), Roger Sperry argues for the unification of science and religion based on the principle of emergent causation within the central nervous system. After illustrating Sperry's position with some current experiments, I suggest that his conclusions exceed his argument and the findings of contemporary neuroscience and propose instead a pluralistic, rather than unified, approach to the relations between religion and science necessitated by the incompleteness inherent in any strictly neurological account of human nature.

Within theoretical and empirical enquiries, many different meanings associated with consciousness have appeared, leaving the term itself quite vague. This makes formulating an abstract and unifying version of the concept of consciousness – the main aim of this article –into an urgent theoretical imperative. It is argued that consciousness, characterized as dually accessible (cognized from the inside and the outside), hierarchically referential (semantically ordered), bodily determined (embedded in the working structures of an organism or conscious system), and useful in action (...) (pragmatically functional), is a graded rather than an all-or-none phenomenon. A gradational approach, however, despite its explanatory advantages, can lead to some counterintuitive consequences and theoretical problems. In most such conceptions consciousness is extended globally (attached to primitive organisms or artificial systems), but also locally (connected to certain lower-level neuronal and bodily processes). For example, according to information integration theory (as introduced recently by Tononi and Koch, 2014), even such simple artificial systems as photodiodes possess miniscule amounts of consciousness. The major challenge for this article, then, is to establish reasonable, empirically justified constraints on how extended the range of a graded consciousness could be. It is argued that conscious systems are limited globally by the ability to individuate information (where individuated information is understood as evolutionarily embedded, socially altered, and private), whereas local limitations should be determined on the basis of a hypothesis about the action-oriented nature of the processes that select states of consciousness. Using these constraints, an abstract concept of consciousness is arrived at, hopefully contributing to a more unified state of play within consciousness studies itself. (shrink)

Book reviewed in this article: Lawrence Weiskrantz, Consciousness Lost and Found: A Neuropsychological Exploration.

Most ?theories of consciousness? are based on vague speculations about the properties of conscious experience. We aim to provide a more solid basis for a science of consciousness. We argue that a theory of consciousness should provide an account of the very processes that allow us to acquire and use information about our own mental states ? the processes underlying introspection. This can be achieved through the construction of information processing models that can account for ?Type-C? processes. Type-C processes can (...) be specified experimentally by identifying paradigms in which awareness of the stimulus is necessary for an intentional action. The Shallice (1988b) framework is put forward as providing an initial account of Type-C processes, which can relate perceptual consciousness to consciously performed actions. Further, we suggest that this framework may be refined through the investigation of the functions of prefrontal cortex. The formulation of our approach requires us to consider fundamental conceptual and methodological issues associated with consciousness. The most significant of these issues concerns the scientific use of introspective evidence. We outline and justify a conservative methodological approach to the use of introspective evidence, with attention to the difficulties historically associated with its use in psychology. (shrink)

Recent philosophy has seen a resurgence of the realist view of sensible qualities such as colour. The view holds that experienced qualities are properties of the objects in the physical environment, not mentally instantiated properties like qualia or merely intentional, illusory ones. Some suggest that this move rids us of the explanatory gap between physical properties and the qualitative features of consciousness. Others say it just relocates the problem of qualities to physical objects in the environment, given that such qualities (...) cannot be derived from the non-qualitative properties of objects, and it does not resolve the problem of consciousness either. I argue that such an outcome is welcome: if the physical world is full of explanatory gaps, then the mind–body explanatory gap is not so special. Moreover, the explanatory gaps regarding qualities of objects are less puzzling than the brain-qualia gap. In order to counter the usual worries concerning realism about objective qualities, I introduce ‘imperfect realism’ as an alternative to colour pluralism and complex reductionism, which accommodates realism in the face of widespread perceptual error. I conclude with a discussion of how this ‘multiple-gaps view’ sits better with a naturalistic framework compared to the Galilean-Cartesian account of qualities. (shrink)

According to constitutive reductionism of Derek Parfit, a subject/person is not a separate existing being but his existence consists in the existence of a brain and body, performance of actions, thinking and occurrence of other physical and mental events. The identity of the subject in time comes down only to “Relation R” - mental consistency and/or connectedness – elicited by appropriate reasons. In the following article, I will try, relying on Frank Johnson's Knowledge Argument, to argue in favour of the (...) following conclusions: a person/subject is a “fact”irreducible to body and physical relations with the environment and a subject is something/”fact” non-reducible to mental occurrences.

In recent years two‐dimensional semantics has become one of the most serious alternatives to Millianism for the proper interpretation of modal discourse. It has origins in the works of a diverse group of philosophers, and it has proven popular as an interpretation of both language and thought. It has probably received most of its attention, however, because of its use by David Chalmers in his arguments against materialism. It is this more metaphysical application of two‐dimensionalism that is the concern in (...) this paper. For though there is probably something salvageable from two‐dimensionalism as a way to explain the content of thought, as a metaphysical tool it should be abandoned. In this paper I aim to establish this point by reductio: if ‘metaphysical’ two‐dimensionalism is assumed, it can be shown to be false. (shrink)

In this paper I argue that Frank Jackson.

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 disagreement about consciousness largely owed to no adequate initial clarification of the subject, to people in fact answering different questions clarified as actual consciousness. Philosophical method like the scientific method includes transition from the figurative to literal theory or analysis. A new theory will also satisfy various criteria not satisfied by many existing theories. The objective physical world has specifiable general characteristics including spatiality, lawfulness, being in science, connections with perception, and so on. Actualism, the literal theory or analysis (...) of actual consciousness, deriving mainly from the figurative database, is that actual consciousness has counterpart but partly different general characteristics. Actual consciousness is thus subjectively physical. So physicality in general consists in objective and also subjective physicality. Consciousness in the case of perception is only the dependent existence of a subjective external physical world out there, often a room. But cognitive and affective consciousness, various kinds of thinking and wanting, differently subjectively physical, is internal – subjectively physical representations-with-attitude, representations that also are actual. They differ from the representations that are lines of type, sounds etc. by being actual. Thus they involve a subjectivity or individuality that is a lawful unity. Actualism, both an externalism and an internalism, does not impose on consciousness a flat uniformuity, and it uniquely satisfies the various criteria for an adequate theory, including naturalism. Actual consciousness is a right subject and is a necessary part of any inquiry whatever into consciousness. All of it is a subject for more science, a workplace. There is no unique barrier or impediment whatever to science, as often said, no want of understanding of the mind-consciousness connection, no known unique hard problem of consciousness, no insuperable difficulty having to do with physicality and the history of science, no arguable ground at all of mysterianism.

This article examines the critique of materialism in the work of Noam Chomsky which treats the doctrine as lacking in any clear content. It is argued that Chomsky’s critique is a coherent one drawing on an understanding of the Newtonian revolution in science, on a modular conception of the mind, and on the related conception of epistemic boundedness. The article also seeks to demonstrate the limits of Chomsky’s position by drawing attention to his use of the third-person point of view (...) in considering the mental and his resulting failure to make good sense of consciousness. Finally, a dual-aspect theory is recommended which would incorporate Chomsky’s agnosticism about the nature of matter. (shrink)

The subjectivity of the mental consists in the idea that there are features of our mental states that are perspectival in that they are accessible only from the first-person point of view. This is held to be a problem for materialist theories of mind, since such theories contend that there is nothing about the mind that cannot be fully described from a third-person point of view. Lycan suggests a notion of “phenomenal information” that is held to be perspectival in the (...) relevant sense but also perfectly objective, since it is explicated in terms of the computational roles of higher-order mental representations. I argue that his project fails because phenomenal information is accessible to observers, and hence it fails to be perspectival in the required sense. That sense demands that there be aspects of our conscious experiences that cannot be intersubjectively compared. (shrink)

In an oft-quoted passage fromThe Principles of Morals and Legislation, Jeremy Bentham addresses the issue of our treatment of animals with the following words: ‘the question is not, Can theyreason? nor, can theytalk? but, Can theysuffer?’ The point is well taken, for surely if animals suffer, they are legitimate objects of our moral concern. It is curious therefore, given the current interest in the moral status of animals, that Bentham's question has been assumed to be merely rhetorical. No-one has seriously (...) examined the claim, central to arguments for animal liberation and animal rights, that animals actually feel pain. Peter Singer'sAnimal Liberationis perhaps typical in this regard. His treatment of the issue covers a scant seven pages, after which he summarily announces that ‘there are no good reasons, scientific or philosophical, for denying that animals feel pain’. In this paper I shall suggest that the issue of animal pain is not so easily dispensed with, and that the evidence brought forward to demonstrate that animals feel pain is far from conclusive.

Against the background of the model of the metaphysics of the person (presented in the article “The Existential Metaphysics of the Person. Part 1: The Classical Concept of the Person and the Metaphysical Theory of Esse,” Studia Gilsoniana 10, no. 2) which was initiated by Thomas Aquinas and developed in the Lublin Philosophical School, this paper focuses on the attempt to show the philosophical breakthrough that the concept of personal existence can bring, and points out the most important theoretical consequences (...) of adopting this theory in metaphysics. It outlines the elements of a new metaphysics of the person, based on the concept of personal existence, and hypothesizes about the metaphysical turn this concept could make. The investigations undertaken in the paper lead to the conclusion that not all inferences have yet been drawn from the concept of esse personale, and that the entire depth of the metaphysics of existence has not yet been explored.

In this paper the explanatory gap of the philosophy of mind is explored, and found to have a similar structure even in different framings of the mind–body problem. This leads to the consideration that the MBP may be a special case of the more general whole-part problem: how do properties of wholes arise from the particular assembly of isolated parts? The conclusion is argued that only an approach of mereological holism offers solace from the explanatory gap problem, exchanging it for (...) a reverse explanatory gap problem that has more promising prospects for future solution, possibly in the form of integrated information theory. These considerations, along with the problem of explaining qualia lead to a proposed solution to the MBP in holistic cosmopsychism. (shrink)

Some opponents of the incommensurability thesis, such as Davidson and Rorty, have argued that the very idea of incommensurability is incoherent and that the existence of alternative and incommensurable conceptual schemes is a conceptual impossibility. If true, this refutes Kuhnian relativism and Kantian scepticism in one fell swoop. For Kuhnian relativism depends on the possibility of alternative, humanly accessible conceptual schemes that are incommensurable with one another, and the Kantian notion of a realm of unknowable things-in-themselves gives rise to the (...) possibility of humanly inaccessible schemes that are incommensurable with even our best current or future science. In what follows we argue that the possibility of incommensurability of either the Kuhnian or the Kantian variety is inescapable and that this conclusion is forced upon us by a simple consideration of what is involved in acquiring a concept. It turns out that the threats from relativism and scepticism are real, and that anyone, including Davidson himself, who has ever defended an account of concept acquisition is committed to one or the other of these two possibilities.1.

Many philosophers and scientists believe that we need an explanation as to why the laws of physics and the initial conditions of the universe are fine-tuned for life. The standard two options are: theism and the multiverse hypothesis. Both of these theories are extravagant and arguably have false predictions. Drawing on contemporary philosophy of mind, I outline a form of panpsychism that I believe offers a more parsimonious and less problematic explanation of cosmological fine-tuning.

The plain man thinks that material objects must certainly exist, since they are evident to the senses. Whatever else may be doubted, it is certain that anything you can bump into must be real; this is the plain man’s metaphysic. This is all very well, but the physicist comes along and shows that you never bump into anything: even when you run your hand along a stone wall, you do not really touch it. When you think you touch a thing, (...) there are certain electrons and protons, forming part of your body, which are attracted and repelled by certain electrons and protons in the thing you think you are touching, but there is no actual contact. … The electrons and protons themselves, however, are only crude first approximations, a way of collecting into a bundle either trains of waves or the statistical probabilities of various different kinds of events. Thus matter has become altogether too ghostly to be used as an adequate stick with which to beat the mind. —Bertrand Russell, “What is the Soul?” 193.. (shrink)

This paper calls into question the viability of materialist reduction of the phenomenal. I revisit the 'Knowledge Argument', which claims that there is information about the phenomenal which is not reducible to, nor even inferable from, information about the physical. I demonstrate the failure of the two chief strategies for blocking the Knowledge Argument: analyzing phenomenal knowledge as an ability, and construing it as knowledge of facts which are ontologically reducible to physical facts. Materialist reduction of the phenomenal is, thus, (...) untenable; materialists must adopt a more extreme, eliminativist view about the phenomenal. (shrink)
