Breaking new ground in the debate about the relation of mind and body, David Armstrong's classic text - first published in 1968 - remains the most compelling and comprehensive statement of the view that the mind is material or physical. In the preface to this new edition, the author reflects on the book's impact and considers it in the light of subsequent developments. He also provides a bibliography of all the key writings to have appeared in the materialist debate.

In 1995, in my book, Ten Problems of Consciousness, I proposed a version of the theory of phenomenal consciousness now known as representationalism. The present book, in part, consists of a further development of that theory along with replies to common objections. It is also concerned with two prominent challenges for any reductive theory of consciousness: the explanatory gap and the knowledge argument. In addition, it connects representationalism with two more general issues: the nature of color and the location of (...) the phylogenetic dividing line between those creatures that are phenomenally conscious and those that are not.

One of the most vivid aspects of consciousness is the experience of emotion, yet this topic is given relatively little attention within consciousness studies. Emotions are crucial, for they provide quick and motivating assessments of value, without which action would be misdirected or absent. Emotions also involve linkages between phenomenal and intentional consciousness. This paper examines emotional consciousness from the standpoint of the representational theory of consciousness . Two interesting developments spring from this. The first is the need for the (...) representation of value, which is distinctive of emotional experience. The second is an extension of RTC’s theory of introspection to emotional states, revealing why emotional consciousness is so often introspective even though introspective abilities are not needed to experience emotions, and also explaining why introspection of emotional states is so much less reliable than that of other states of consciousness.

Russell's version of the multiple-relation theory from the "Theory of Knowledge" manuscript is presented and defended against some objections. A new problem, related to defining truth via correspondence, is reconstructed from Russell's remarks and what we know of Wittgenstein's objection to Russell's theory. In the end, understanding this objection in terms of correspondence helps to link Russell's multiple-relation theory to his later views on propositions.

According to a common account, grammatical mood is merely a conventional indicator of force with no semantic significance. Focusing on indicatives, interrogatives and imperatives, I advance two reasons to reject this “force treatment” of mood. First, it can be shown that the mood of a subordinate clause can have semantic significance that affects the sense of a sentence in which it is embedded—which the force treatment cannot accommodate. Second, the speech acts of asserting, asking and ordering have something in common (...) even when they do not involve the same descriptive content, namely, the commitment that is present when one speaks seriously for oneself. The force treatment cannot accommodate the fact that when we subtract this positive force from the act, what we are left with is not bare descriptive content, but the mere expression of a proposition, question or order (as appropriate). I conclude by suggesting that the sense of a mood indicator is a function from descriptive content to a proposition, question or order. (shrink)

How the various things that are said to have meaning—purpose, natural signs, linguistic signs, perceptions, and thoughts—are related to one another.

A list of groceries, Professor Anscombe once suggested, might be used as a shopping list, telling what to buy, or it might be used as an inventory list, telling what has been bought (Anscombe 1957). If used as a shopping list, the world is supposed to conform to the representation: if the list does not match what is in the grocery bag, it is what is in the bag that is at fault. But if used as an inventory list, the (...) representation is supposed to conform to the world: if the list does not match what is in the bag, it is the list that is at fault. The first kind of representation, where the world is supposed to conform to the list, can be called "directive"; it represents or directs what is to be done. The second, where the list is supposed to conform to the world, can be called "descriptive"; it represents or describes what is the case. I wish to propose that there exist representations that face both these ways at once. With apologies to Dr. Doolittle, I call them pushmi-pullyu representations or PPRs. (shrink)

Locke put forward the theory of consciousness as "internal Sense" or "reflection"; Kant made it inner sense, by means of which the mind intuits itself or its inner state." On that theory, consciousness is a perception-like second-order representing of our own psychological states events. The term "consciousness," of course, has many distinct uses.

The paper's first four sections give a taxonomy and criticism of three classes of objections to the argument from illusion. the last section raises the question whether its main premise does not misclassify perceptual accusatives (e.g. 'sensation of bentness') as individuatives that imply the existence of, say, bent particulars.

Many bodily sensations are connected quite closely with specific actions: itches with scratching, for example, and hunger with eating. Indeed, these connections have the feel of conceptual connections. With the exception of D. M. Armstrong, philosophers have largely neglected this aspect of bodily sensations. In this paper, I propose a theory of bodily sensations that explains these connections. The theory ascribes intentional content to bodily sensations but not, strictly speaking, representational content. Rather, the content of these sensations is an imperative: (...) in the case of itches, 'Scratch!' The view avoids non-intentional qualia and hence accords with what could be called, generalizing Lycan slightly, the 'hegemony of intentionality'. (shrink)

This book presents an attempt to develop a theory of knowledge and a philosophy of mind using ideas derived from the mathematical theory of communication developed by Claude Shannon. Information is seen as an objective commodity defined by the dependency relations between distinct events. Knowledge is then analyzed as information caused belief. Perception is the delivery of information in analog form for conceptual utilization by cognitive mechanisms. The final chapters attempt to develop a theory of meaning by viewing meaning as (...) a certain kind of information-carrying role. (shrink)

Higher‐order theories purport to account for the conscious character of such states in terms of higher‐order representations. This chapter focuses on three classes of higher‐order theory of phenomenal consciousness, including inner‐sense theory, actualist higher‐order thought theory, and dispositionalist higher‐order thought theory. All three of these higher‐order theories purport to offer reductive explanations of phenomenal consciousness. Inner‐sense theory has important positive virtues, but faces problems; whereas actualist higher‐order thought theory avoids those problems, but at the cost of losing the positive virtues. (...) Actualist higher‐order thought theory has the advantage that no special organs or mechanisms need to be postulated. Dispositionalist higher‐order thought theory claims to split the difference, providing an account that has all of the advantages of inner‐sense theory with none of the flaws. The success of dispositionalist higher‐order thought theory is premised upon the existence of dual analog contents. (shrink)

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.

A further development of Tye's theory of phenomenal consciousness along with replies to common objections.

Consciousness and Mind presents David Rosenthal's influential work on the nature of consciousness. Central to that work is Rosenthal's higher-order-thought theory of consciousness, according to which a sensation, thought, or other mental state is conscious if one has a higher-order thought that one is in that state. The first four essays develop various aspects of that theory. The next three essays present Rosenthal's homomorphism theory of mental qualities and qualitative consciousness, and show how that theory fits with and helps sustain (...) the HOT theory. A crucial feature of homomorphism theory is that it individuates and taxonomizes mental qualities independently of the way we're conscious of them, and indeed independently of our being conscious of them at all. So the theory accommodates the qualitative character not only of conscious sensations and perceptions, but also of those which fall outside our stream of consciousness. Rosenthal argues that, because this account of mental qualities makes no appeal to consciousness, it enables us to dispel such traditional quandaries as the alleged conceivability of undetectable quality inversion, and to disarm various apparent obstacles to explaining qualitative consciousness and understanding its nature. Six further essays build on the HOT theory to explain various important features of consciousness, among them the complex connections that hold in humans between consciousness and speech, the self-interpretative aspect of consciousness, and the compelling sense we have that consciousness is unified. Two of the essays, one an extended treatment of homomorphism theory, appear here for the first time. There is also a substantive introduction, which draws out the connections between the essays and highlights their implications. (shrink)

What does feeling a sharp pain in one's hand have in common with seeing a red apple on the table? Some say not much, apart from the fact that they are both conscious experiences. To see an object is to perceive an extramental reality -- in this case, a red apple. To feel a pain, by contrast, is to undergo a conscious experience that doesn't necessarily relate the subject to an objective reality. Perceptualists, however, dispute this. They say that both (...) experiences are forms of perception of an objective reality. Feeling a pain in one's hand, according to this view, is perceiving an objective condition of one's hand. Who is closer to truth? Because of such metaphysical issues, the subjectivity of pains combined with their clinical urgency raises methodological problems for pain scientists. How can a subjective phenomenon be studied objectively? What is the role of the first-person method in science? Some suggest that the subjectivity of pains is due to their metaphysical irreducibility to purely physical processes in the nervous system. Can this be true? The study of pain and its puzzles offers opportunities for understanding such larger issues as the place of consciousness in the natural order and the methodology of psychological research. In this book, leading philosophers and scientists offer a wide range of views on how to conceptualize and study pain. The essays include discussions of perceptual and representationalist accounts of pain; the affective-motivational dimension of pain; whether animals feel pain, and how this question can be investigated; how social pain relates to physical pain; whether first-person methods of gathering data can be integrated with standard third-person methods; and other methodological and theoretical issues in the science and philosophy of pain.

How can phenomenal consciousness exist as an integral part of a physical universe? How can the technicolour phenomenology of our inner lives be created out of the complex neural activities of our brains? Many have despaired of finding answers to these questions; and many have claimed that human consciousness is inherently mysterious. Peter Carruthers argues, on the contrary, that the subjective feel of our experience is fully explicable in naturalistic terms. Drawing on a variety of interdisciplinary resources, he develops and (...) defends a novel account in terms of higher-order thought. He shows that this can explain away some of the more extravagant claims made about phenomenal consciousness, while substantively explaining the key subjectivity of our experience. Written with characteristic clarity and directness, and surveying a wide range of extant theories, this book is essential reading for all those within philosophy and psychology interested in the problem of consciousness.

Reductive, naturalistic psychosemantic theories do not have a good track record when it comes to accommodating the representation of kinds. In this paper, I will suggest a particular teleosemantic strategy to solve this problem, grounded in the neurocomputational details of the cerebral cortex. It is a strategy with some parallels to one that Ruth Millikan has suggested, but to which insufficient attention has been paid. This lack of attention is perhaps due to a lack of appreciation for the severity of (...) the problem, so I begin by explaining why the situation is indeed a dire one. One of the main tasks for a naturalistic psychosemantic theory is to describe how the extensions of mental representations are determined. (Such a theory may also attempt to account for other aspects of the “meaning” of mental representations, if there are any.) Some mental representations, e.g. the concept of water, denote kinds (I shall be assuming this is non-negotiable). How is this possible? Unfortunately, I haven’t the space to canvass all the theories out there and show that each one fails to accommodate the representation of kinds, but I will point out the major types of problems that arise for the kinds of theories that, judging by the literature, are considered viable contenders.1 In general, the theories either attempt and fail to account for the representation of kinds, or they fall back on something like an intention to refer to a kind – not exactly the most auspicious move for a reductive theory. There are a number of problems that prevent non-teleosemantic theories from explaining how it is possible to represent kinds. A concept of a kind K must.. (shrink)

Sense data are the alleged mind-dependent objects that we are directly aware of in perception, and that have exactly the properties they appear to have. For instance, sense data theorists say that, upon viewing a tomato in normal conditions, one forms an image of the tomato in one's mind. This image is red and round. The mental image is an example of a “sense datum.” Many philosophers have rejected the notion of sense data, either because they believe that perception gives (...) us direct awareness of physical phenomena, rather than mere mental images, or because they believe that the mental phenomena involved in perception do not have the properties that appear to us (for instance, I might have a visual experience representing a red, round tomato, but my experience is not itself red or round). Defenders of sense data have argued, among other things, that sense data are required to explain such phenomena as perspectival variation, illusion, and hallucination. Critics of sense data have objected to the theory's commitment to mind-body dualism, the problems it raises for our knowledge of the external world, its difficulty in locating sense data in physical space, and its apparent commitment to the existence of objects with indeterminate properties.

Our subjective sensory experiences are thought to be heavily shaped by interactions between expectations and incoming sensory information. However, the neural mechanisms supporting these interactions remain poorly understood. By using combined psychophysical and functional MRI techniques, brain activation related to the intensity of expected pain and experienced pain was characterized. As the magnitude of expected pain increased, activation increased in the thalamus, insula, prefrontal cortex, anterior cingulate cortex (ACC) and other brain regions. Pain-intensity-related brain activation was identified in a widely (...) distributed set of brain regions but overlapped partially with expectation-related activation in regions, including the anterior insula and ACC. When expected pain was manipulated, expectations of decreased pain powerfully reduced both the subjective experience of pain and activation of pain-related brain regions, such as the primary somatosensory cortex, insular cortex, and ACC. These results confirm that a mental representation of an impending sensory event can significantly shape neural processes that underlie the formulation of the actual sensory experience and provide insight as to how positive expectations diminish the severity of chronic disease states.

This paper examines pain states (and other intransitive bodily sensations) from the perspective of the problems they pose for pure informational/representational approaches to naturalizing qualia. I start with a comprehensive critical and quasi-historical discussion of so-called Perceptual Theories of Pain (e.g., Armstrong, Pitcher), as these were the natural predecessors of the more modern direct realist views. I describe the theoretical backdrop (indirect realism, sense-data theories) against which the perceptual theories were developed. The conclusion drawn is that pure representationalism about pain (...) in the tradition of direct realist perceptual theories (e.g., Dretske, Tye) leaves out something crucial about the phenomenology of pain experiences, namely, their affective character. I touch upon the role that introspection plays in such representationalist views, and indicate how it contributes to the source of their trouble vis-à-vis bodily sensations. The paper ends by briefly commenting on the relation between the affective/evaluative component of pain and the hedonic valence of emotions. (shrink)

Representationism 1, as I use the term, says that the phenomenal character of an experience just is its representational content, where that representational content can itself be understood and characterized without appeal to phenomenal character. Representationists seem to have a harder time handling pain than visual experience. I will argue that Michael Tye's heroic attempt at a representationist theory of pain, although ingenious and enlightening, does not adequately come to terms with the root of this difference.

This essay surveys representationalist theories of phenomenal consciousness as well as the major arguments for them. It also takes up two major objections. The essay is divided into five sections. Section I offers some introductory remarks on phenomenal consciousness. Section II presents the classic view of phenomenal consciousness to which representationalists are opposed. Section III canvasses various versions of representationalism about consciousness. Section IV lays out the main arguments for the representationalist stance. The final section addresses the two objections.
