This much-anticipated book is a detailed elaboration and defense of Levine’s influential claim that there is an “explanatory gap” between the mental and the physical.

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.

No mental phenomenon is more central than consciousness to an adequate understanding of the mind. Nor does any mental phenomenon seem more stubbornly to resist theoretical treatment. Consciousness is so basic to the way we think about the mind that it can be tempting to suppose that no mental states exist that are not conscious states. Indeed, it may even seem mysterious what sort of thing a mental state might be if it is not a conscious state. On this way (...) of looking at things, if any mental states do lack consciousness, they are exceptional cases that call for special explanation or qualification. Perhaps dispositional or cognitive states exist that are not conscious, but nonetheless count as mental states. (shrink)

be realized. Whatever gets access to phenomenal awareness is represented within this absent together.

Ned BlockÕs influential distinction between phenomenal and access consciousness has become a staple of current discussions of consciousness. It is not often noted, however, that his distinction tacitly embodies unargued theoretical assumptions that favor some theoretical treatments at the expense of others. This is equally so for his less widely discussed distinction between phenomenal consciousness and what he calls reflexive consciousness. I argue that the distinction between phenomenal and access consciousness, as Block draws it, is untenable. Though mental states that (...) have qualitative character plainly differ from those with no mental qualities, a mental stateÕs being conscious is the same property for both kinds of mental state. For one thing, as Block describes access consciousness, that notion does not pick out any property that we intuitively count as a mental stateÕs being conscious. But the deeper problem is that BlockÕs notion of phenomenal consciousness, or phenomenality, is ambiguous as between two very different mental properties. The failure to distinguish these results in the begging of important theoretical questions. Once the two kinds of phenomenality have been distinguished, the way is clear to explain qualitative consciousness by appeal to a model such as the higher-order-thought hypothesis.

Because metacognition consists in our having mental access to our cognitive states and mental states are conscious only when we are conscious of them in some suitable way, metacognition and consciousness shed important theoretical light on one another. Thus, our having metacognitive access to information carried by states that are not conscious helps con?rm the hypothesis that a mental state.

Recent writing on consciousness has increasingly stressed ways in which the terms.

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 word ?consciousness? is notoriously ambiguous. This is mainly because it is not a term of art, but a mundane word we all use quite frequently, for different purposes and in different everyday contexts. In this paper, I discuss consciousness in one specific sense of the word. To avoid the ambiguities, I introduce a term of art ? intransitive self-consciousness ? and suggest that this form of self-consciousness is an essential component of the folk notion of consciousness. I then argue (...) for a specific account of consciousness as intransitive self-consciousness. According to this account, a mental state is conscious iff it represents its own occurrence. The argument is a ?modernizing? modification of an older argument due to Aristotle and Brentano. (shrink)

This paper supports the basic integrity of the folk psychological conception of consciousness and its importance in cognitive theorizing. Section 1 critically examines some proposed definitions of consciousness, and argues that the folk- psychological notion of phenomenal consciousness is not captured by various functional-relational definitions. Section 2 rebuts the arguments of several writers who challenge the very existence of phenomenal consciousness, or the coherence or tenability of the folk-psychological notion of awareness. Section 3 defends a significant role for phenomenal consciousness (...) in the execution of a certain cognitive task, viz., classification of one's own mental states. Execution of this task, which is part of folk psychologizing, is taken as a datum in scientific psychology. It is then argued that the most promising sort of scientific model of the self-ascription of mental states is one that posits the kinds of phenomenal properties invoked by folk psychology. Cognitive science and neuroscience can of course refine and improve upon the folk understanding of consciousness, awareness, and mental states generally. But the folk-psychological constructs should not be jettisoned; they have a role to play in cognitive theorizing. (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.

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.

There are two broad classes of empirical theories of consciousness, which I will call the biological and the functional. The biological approach is based on empirical correlations between experience and the brain. For example, there is a great deal of evidence that the neural correlate of visual experience is activity in a set of occipetotemporal pathways, with special emphasis on the infero-temporal cortex. The functionalist approach is a successor of behaviorism, the view that mentality can be seen as tendencies to (...) emit certain behavioral outputs given certain sensory inputs. The trouble with behaviorism is that it did not allow that mental states were causes and effects, but functionalists do allow this. They characterize consciousness in terms of its causal role: the causal influence on it from inputs and other mental states, and its causal efficacy with respect to other mental states and behavior. The central idea of functionalism is a proposal about the concept of consciousness, but scientific functionalists have filled the view in with empirical details—the idea is that a representation is conscious if it is broadcast in a global neuronal workspace. The functional approach says consciousness is a role, whereas the biological approach says consciousness is a realizer of that role. For example, one could take solubility to be a role—dissolving in certain circumstances—or, as with the biological view of consciousness, the physico-chemical configuration that has that role. The.

A touchstone of much modern theorizing about the mind is the idea, still tac- itly accepted by many, that a state's being mental implies that it's conscious. This view is epitomized in the dictum, put forth by theorists as otherwise di-.
