How is consciousness possible? What biological purpose does it serve? And why do we value it so highly? In Soul Dust, the psychologist Nicholas Humphrey, a leading figure in consciousness research, proposes a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us and makes us feel special and transcendent. Thus consciousness paves the way for spirituality, and allows us, (...) as human beings, to reap the rewards, and anxieties, of living in what Humphrey calls the "soul niche." Tightly argued, intellectually gripping, and a joy to read, Soul Dust provides answers to the deepest questions. It shows how the problem of consciousness merges with questions that obsess us all--how life should be lived and the fear of death. Resting firmly on neuroscience and evolutionary theory, and drawing a wealth of insights from philosophy and literature, Soul Dust is an uncompromising yet life-affirming work--one that never loses sight of the majesty and wonder of consciousness.

Robert Stalnaker opposes the traditional view that knowledge of one's own current thoughts and feelings is the unproblematic foundation for all knowledge. He argues that we can understand our knowledge of our thoughts and feelings only by viewing ourselves from the outside, by seeing our inner lives as features of the world as it is in itself.

We are material beings in a material world, but we are also beings who have experiences and feelings. How can these subjective states be just a matter of matter? To defend materialism, philosophical materialists have formulated what is sometimes called "the phenomenal-concept strategy," which holds that we possess a range of special concepts for classifying the subjective aspects of our experiences. In Consciousness Revisited, the philosopher Michael Tye, until now a proponent of the the phenomenal-concept strategy, argues that the strategy (...) is mistaken. A rejection of phenomenal concepts leaves the materialist with the task of finding some other strategy for defending materialism. Tye points to four major puzzles of consciousness that arise: How is it possible for Mary, in the famous thought experiment, to make a discovery when she leaves her black-and-white room? In what does the explanatory gap consist and how can it be bridged? How can the hard problem of consciousness be solved? How are zombies possible? Tye presents solutions to these puzzles -- solutions that relieve the pressure on the materialist created by the failure of the phenomenal-concept strategy. In doing so, he discusses and makes new proposals on a wide range of issues, including the nature of perceptual content, the conditions necessary for consciousness of a given object, the proper understanding of change blindness, the nature of phenomenal character and our awareness of it, whether we have privileged access to our own experiences, and, if we do, in what such access consists.

In this paper I begin to develop an account of the acquaintance that each of us has with our own conscious states and processes. The account is a speculative proposal about human mental architecture and specifically about the nature of the concepts via which we think in first personish ways about our qualia. In a certain sense my account is neutral between physicalist and dualist accounts of consciousness. As will be clear, a dualist could adopt the account I will offer (...) while maintaining that qualia themselves are non-physical properties. In this case the non-physical nature of qualia may play no role in accounting for the features of acquaintance. But although the account could be used by a dualist, its existence provides support for physicalism. (shrink)

In this wide-ranging study, Levine explores both sides of the mind-body dilemma, presenting the first book-length treatment of his highly influential ideas on the How does one explain the physical nature of an experience? This puzzle, the "explanatory gap" between mind and body, is the focus of this work by an influential scholar in the field.

There are two main ways in which things with minds, like us, differ from things without minds, like tables and chairs. First, we are conscious--there is something that it is like to be us. We instantiate phenomenal properties. Second, we represent, in various ways, our world as being certain ways. We instantiate representational properties. Jeff Speaks attempts to make progress on three questions: What are phenomenal properties? What are representational properties? How are the phenomenal and the representational related?

What do thoughts, hopes, paintings, words, desires, photographs, traffic signs, and perceptions have in common? They are all about something, are directed, are contentful - in a way chairs and trees, for example, are not. This book inquires into the source of this power of directedness that some items exhibit while others do not. An approach to this issue prevalent in the philosophy of the past half-century seeks to explain the power of directedness in terms of certain items' ability to (...) reliably track things in their environment. A very different approach, with a venerable history and enjoying a recent resurgence, seeks to explain the power of directedness rather in terms of an intrinsic ability of conscious experience to direct itself. This book attempts a synthesis of both approaches, developing an account of the sources of such directedness that grounds it both in reliable tracking and in conscious experience. (shrink)

The Phenomenal Concept Strategy offers the physicalist perhaps the most promising means of explaining why the connection between mental facts and physical facts appears to be contingent even though it is not. In this article, we show that the large body of evidence suggesting that our concepts are often embodied and grounded in sensorimotor systems speaks against standard forms of the PCS. We argue, nevertheless, that it is possible to formulate a novel version of the PCS that is thoroughly in (...) keeping with embodied cognition, focuses on features of physical concepts, and succeeds in explaining the appearance of contingency.

Published annually, this book brings together original and first-rate articles written by leading scholars in the field of philosophy.

Phenomenal concepts are the concepts that we deploy when – but arguably not only when – we introspectively examine, focus on, or take notice of the phenomenal character of our experiences. They refer to phenomenal properties (or qualities) and they do so in a subjective (first-personal) and direct (non-relational) manner. It is through the use of such concepts that the phenomenal character of our experiences is made salient to us. Discourse about the nature of phenomenal concepts plays an important role (...) in the philosophy of mind. For one, phenomenal concepts have been used to explain the epistemological relation that holds between a subject and her conscious mental states. Most prominently, however, discussions of phenomenal concepts figure in the on-going and multifaceted debate concerning the metaphysical status of consciousness. Even though some theorists have utilized phenomenal concepts in arguments purporting to show that consciousness is ontologically distinct from physical entities and processes, most accounts of phenomenal concepts are advanced having the opposite objective in mind: a proper articulation of the nature of phenomenal concepts, it is held, can defend the view that consciousness is physical against epistemic arguments to the contrary. The present entry focuses on the nature of phenomenal concepts as this is articulated and developed in attempts to defend the contention that conscious states are identical to (realized by, metaphysically necessitated by, or supervenient upon) physical states.

This paper compares tracking and phenomenal intentionality theories of intentionality with respect to the issue of naturalism. Tracking theories explicitly aim to naturalize intentionality, while phenomenal intentionality theories generally do not. It might seem that considerations of naturalism count in favor of tracking theories. We survey key considerations relevant to this claim, including some motivations for and objections to the two kinds of theories. We conclude by suggesting that naturalistic considerations may in fact support phenomenal intentionality theories over tracking theories.

Theories that combine physicalism with phenomenal concepts abandon the phenomenal irrealism characteristic of 1950s physicalism, thereby leaving physicalists trying to reconcile themselves to concepts appropriate only to dualism. Physicalists should instead abandon phenomenal concepts and try to develop our concepts of conscious states. Employing an account of concepts as structured mental representations, and motivating a model of conceptual development with semantic externalist considerations, I suggest that phenomenal concepts misrepresent their referents, such that if our conception of consciousness incorporates them, it (...) needs development. I then argue that the ?phenomenal concept strategy? (PCS) of a purely cognitive account of the distinction between phenomenal and physical concepts combines physicalism with phenomenal concepts only by misrepresenting physical properties. This is because phenomenal concepts carry ontological commitment, and I present an argument to show the tension between this commitment and granting ontological authority to physical concepts only. In the final section, I show why phenomenal concepts are more ontologically committed than PCS theorists can allow, revive U.T. Place's notion of a ?phenomenological fallacy? to explain their enduring appeal, and then suggest some advantages of functional analyses of concepts of conscious states over the phenomenal alternative.

Humans can think about their conscious experiences using a special class of ?phenomenal? concepts. Psychophysical identity statements formulated using phenomenal concepts appear to be contingent. Kripke argued that this intuited contingency could not be explained away, in contrast to ordinary theoretical identities where it can. If the contingency is real, property dualism follows. Physicalists have attempted to answer this challenge by pointing to special features of phenomenal concepts that explain the intuition of contingency. However no physicalist account of their distinguishing (...) features has proven to be satisfactory. Leading accounts rely on there being a phenomenological difference between tokening a physical-functional concept and tokening a phenomenal concept. This paper shows that existing psychological data undermine that claim. The paper goes on to suggest that the recalcitrance of the intuition of contingency may instead by explained by the limited means people typically have for applying their phenomenal concepts. Ways of testing that suggestion empirically are proposed. (shrink)

This paper replies to objections from perceptual distortion against the representationalist thesis that the phenomenal characters of experiences supervene on their intentional contents. It has been argued that some pairs of distorted and undistorted experiences share contents without sharing phenomenal characters, which is incompatible with the supervenience thesis. In reply, I suggest that such cases are not counterexamples to the representationalist thesis because the contents of distorted experiences are always impoverished in some way compared to those of normal experiences. This (...) can be shown by considering limit cases of perceptual distortion, for example, maximally blurry experiences, which manifestly lack details present in clear experiences. I argue that since there is no reasonable way to draw the line between distorted experiences that have degraded content and distorted experiences that do not, we should allow that an increase in distortion is always accompanied by a change in content. This applies to perceptual distortions due to blur, double vision, perspective, and illumination conditions. (shrink)

In the nearly half a century since its modern inception (Anscombe (1965), Hintikka (1969)), the Representation theory has faced no more implacable enemy than Ned Block. He has offered objection after objection, usually in the form of apparent counterexamples, and as I write this he shows no sign of flagging.

Frank Jackson’s famous Knowledge Argument moves from the premise that complete physical knowledge is not complete knowledge about experiences to the falsity of physicalism. In recent years, a consensus has emerged that the credibility of this and other well-known anti-physicalist arguments can be undermined by allowing that we possess a special category of concepts of experiences, phenomenal concepts, which are conceptually independent from physical/functional concepts. It is held by a large number of philosophers that since the conceptual independence of phenomenal (...) concepts does not imply the metaphysical independence of phenomenal properties, physicalism is safe. This paper distinguishes between two versions of this novel physicalist strategy –Phenomenal Concept Strategy (PCS) – depending on how it cashes out “conceptual independence,” and argues that neither helps the physicalist cause. A dilemma for PCS arises: cashing out “conceptual independence” in a way compatible with physicalism requires abandoning some manifest phenomenological intuitions, and cashing it out in a way compatible with those intuitions requires dropping physicalism. The upshot is that contra Brian Loar and others, one cannot “have it both ways.”. (shrink)

In this book, Derk Pereboom explores how physicalism might best be formulated and defended against the best anti-physicalist arguments. Two responses to the knowledge and conceivability arguments are set out and developed. The first exploits the open possibility that introspective representations fail to represent mental properties as they are in themselves; specifically, that introspection represents phenomenal properties as having certain characteristic qualitative natures, which these properties might actually lack. The second response draws on the proposal that currently unknown fundamental intrinsic (...) properties provide categorical bases for known physical properties and would also yield an account of consciousness. While there are non-physicalist versions of this position, some are amenable to physicalism. The book's third theme is a defense of a nonreductive account of physicalism. The type of nonreductivism endorsed departs from others in that it rejects all token identity claims for psychological and microphysical entities. The deepest relation between the mental and the microphysical is constitution, where this relation is not to be explicated by the notion of identity. (shrink)

This paper presents an ‘over-representational’ account of blurred visual experiences. The basic idea is that blurred experiences provide too much, inconsistent, information about objects’ spatial boundaries, by representing them as simultaneously located at multiple locations. This account attempts to avoid problems with alternative accounts of blurred experience, according to which blur is a property of a visual field, a way of perceiving, a form of mis-representation, and a form of under-representation.

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.

It is one thing to have phenomenal states and another thing to think about phenomenal states. Thinking about phenomenal states gives us knowledge that we have them and knowledge of what they are like. But how do we think about phenomenal states? These days, the most popular answer is that we use phenomenal concepts. Phenomenal concepts are presumed to be concepts that represent phenomenal states in a special, intrinsically phenomenal, way. The special nature of phenomenal concepts is said to be (...) important for defending materialism against epistemic arguments for dualism. In this paper I present an account of phenomenal knowledge that does not depend on phenomenal concepts. In fact, I argue that we have no phenomenal concepts. Instead my account appeals to mental pointing, a process that I explain in terms of phenomenal demonstratives. Phenomenal demonstratives are sometimes referred to as concepts in the literature, but I suggest that this is a mistake. I also present a theory of phenomenal demonstratives that equates them with attentional control structures in working memory. In a concluding section I describe how this theory can be used to defuse the knowledge argument for dualism. That is only a subsidiary goal, and my response to the knowledge argument echoes others in the literature. I think the project of developing a substantive, empirically informed theory of phenomenal knowledge has interest independent of debates about mental ontology. That is my central focus. Thinking about phenomenal knowledge can shed light on the relationship between consciousness, attention and memory. This paper has a philosophical agenda and an empirical agenda. Those who reject my philosophical claims about the nonexistence of phenomenal concepts, the conditions.. (shrink)

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them. This argument is defended against several objections. Then I use what I call “minimal pair” experiences—sentences read without and with understanding—to induce in the reader an experience of the kind I claim exists. Further objections are considered and rebutted. (shrink)

It's a common idea in philosophy that we possess a peculiar kind of "phenomenal concept" by which we can think about our conscious states in "inner" and "direct" ways, as for example, when I attend to the way a current pain feels and think about this feeling as such. Such phenomenal ways of thinking figure in a variety of theoretical contexts. The bulk of this article discusses their use in a certain strategy – the phenomenal concept strategy – for defending (...) the physicalist view that conscious states are reducible to brain states. It also considers, more briefly, how phenomenal concepts have been used to defend dualism about consciousness, and how they have been used to explain our special access to our consciousness. It concludes with a discussion about whether, and in what more precise sense of the term, we at all possess "phenomenal concepts" of our conscious states. (shrink)

Much of recent philosophy of perception is oriented towards accounting for the phenomenal character of perception—what it is like to perceive—in a non-mentalistic way—that is, without appealing to mental objects or mental qualities. In opposition to such views, I claim that the phenomenal character of perception of a red round object cannot be explained by or reduced to direct awareness of the object, its redness and roundness—or representation of such objects and qualities. Qualities of perception that are not captured by (...) what one is directly aware of or by representational content are instances of what Gilbert Harman has called “mental paint” (Block, 1990; Harman, 1990). The claim of this paper is that empirical facts about attention point in the direction of mental paint. The argument starts with the claim (later modified) that when one moves one's attention around a scene while keeping one's eyes fixed, the phenomenology of perception can change in ways that do not reflect which qualities of objects one is directly aware of or the way the world is represented to be. These changes in the phenomenology of perception cannot be accounted for in terms of awareness of or representation of the focus of attention because they manifest themselves in experience as differences in apparent contrast, apparent color saturation, apparent size, apparent speed, apparent time of occurrence and other appearances. There is a way of coping with these phenomena in terms of vague contents, but vague contents cannot save direct realism or representationism because the kind of vagueness required clashes wth the phenomenology itself.

Phenomenal intentionality is supposed to be a kind of directedness of the mind onto the world that is grounded in the conscious feel of mental life. This book of new essays explores a number of issues raised by the notion of phenomenal intentionality.

Consciousness is perhaps the most puzzling problem we humans face in trying to understand ourselves. It has been the subject of intense study for several decades, but, despite substantial progress, the most difficult problems have still not reached any generally agreed solution. Future research can start with this book. Eighteen original, specially written essays offer new angles on the subject. The contributors, who include many of the leading figures in philosophy of mind, discuss such central topics as intentionality, phenomenal content, (...) knowledge of mental states, consciousness and the brain, and the relevance of quantum mechanics to the study of consciousness.

Drawing on the findings of neuroscience, this text proposes and defends the hypothesis that the various modalities of sensation share a generic form that the author, Austen Clark, calls feature-placing.

I argue that perceptual content is always affected by the allocation of one’s attention. Perception attributes determinable and determinate properties to the perceived scene. Attention makes (or tries to make) our perceptual attribution of properties more determinate. Hence, a change in our attention changes the determinacy of the properties attributed to the perceived scene.

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)

There are powerful reasons to think of perceptual content as determined at least in part by the environment of the perceiving subject. Externalist views such as this are often rejected on grounds that they do not give a good account of hallucinations. The chapter shows that this reason for rejecting content externalism is not well founded if we embrace a moderate externalism about content, that is, an externalist view on which content is only in part dependent on the experiencing subject“s (...) environment. The chapter starts by motivating content externalism. It then argues that hallucinations are best understood in terms of a deficiency of veridical perceptual experiences. The chapter discusses the consequences of this thesis by developing a view of hallucinations that is committed to externalism about content. (shrink)

With this third edition of Nelson Goodman's The Structure of Appear ance, we are pleased to make available once more one of the most in fluential and important works in the philosophy of our times. Professor Geoffrey Hellman's introduction gives a sustained analysis and appreciation of the major themes and the thrust of the book, as well as an account of the ways in which many of Goodman's problems and projects have been picked up and developed by others. Hellman also (...) suggests how The Structure of Appearance introduces issues which Goodman later continues in his essays and in the Languages of Art. There remains the task of understanding Good man's project as a whole; to see the deep continuities of his thought, as it ranges from logic to epistemology, to science and art; to see it therefore as a complex yet coherent theory of human cognition and practice. What we can only hope to suggest, in this note, is the b. road Significance of Goodman's apparently technical work for philosophers, scientists and humanists. One may say of Nelson Goodman that his bite is worse than his bark. Behind what appears as a cool and methodical analysis of the conditions of the construction of systems, there lurks a radical and disturbing thesis: that the world is, in itself, no more one way than another, nor are we. It depends on the ways in which we take it, and on what we do. (shrink)

I argue that perception is necessarily situation-dependent. The way an object is must not just be distinguished from the way it appears and the way it is represented, but also from the way it is presented given the situational features. First, I argue that the way an object is presented is best understood in terms of external, mind-independent, but situation-dependent properties of objects. Situation-dependent properties are exclusively sensitive to and ontologically dependent on the intrinsic properties of objects, such as their (...) shape, size, and color, and the situational features, such as the lighting conditions and the perceiver’s location in relation to the perceived object. Second, I argue that perceiving intrinsic properties is epistemically dependent on representing situation-dependent properties. Recognizing situation-dependent properties yields four advantages. It makes it possible to embrace the motivations that lead to phenomenalism and indirect realism by recognizing that objects are presented a certain way, while holding on to the intuition that subjects directly perceive objects. Second, it acknowledges that perceptions are not just individuated by the objects they are of, but by the ways those objects are presented given the situational features. Third, it allows for a way to accommodate the fact that there is a wide range of viewing conditions or situational features that can count as normal. Finally, it makes it possible to distinguish perception and thought about the same object with regard to what is represented. (shrink)

This chapter analyzes aspects of the relationship between consciousness and intentionality. It focuses on the phenomenal character and the intentional content of perceptual states, canvassing various possible relations among them. It argues that there is a good case for a sort of representationalism, although this may not take the form that its advocates often suggest. By mapping out some of the landscape, the chapter tries to open up territory for different and promising forms of representationalism to be explored in the (...) future. In particular, it argues for a nonreductive, narrow, and Fregean variety of representationalism, which contrasts strongly with more widely explored varieties. It concludes with some words about the fundamental relationship between consciousness and intentionality. (shrink)
