What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have contents. She then introduces a (...) method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision. (shrink)

Wittgenstein finished part 1 of the Philosophical Investigations in the spring of 1945. From 1946 to 1949 he worked on the philosophy of psychology almost without interruption. The present two-volume work comprises many of his writings over this period. Some of the remarks contained here were culled for part 2 of the Investigations ; others were set aside and appear in the collection known as Zettel . The great majority, however, although of excellent quality, have hitherto remained unpublished. This bilingual (...) edition of the Remarks on the Philosophy of Psychology presents the first English translation of an essential body of Wittegenstein's work. It elaborates Wittgenstein's views on psychological concepts such as expectation, sensation, knowing how to follow a rule, and knowledge of the sensations of other persons. It also shows strong emphasis on the "anthropological" aspect of Wittgenstein's thought. Philosophers, as well as anthropologists, psychologists, and sociologists will welcome this important publication. (shrink)

This paper defends a novel view of ‘what it is like’-sentences, according to which they attribute certain sorts of relations—I call them ‘affective relations’—that hold between events and individuals. The paper argues in detail for the superiority of this proposal over other views that are prevalent in the literature. The paper further argues that the proposal makes better sense than the alternatives of the widespread use of Nagel’s definition of conscious states and that it also shows the mistakes in two (...) prominent suggestions about the definition when properly understood: first, that it is empty and uninformative, and second, that it leads directly to a substantial claim in the theory of consciousness, namely that an individual is in a conscious state only if the individual is aware of their being in that state.

It is common for philosophers to hold that experience can be characterized in a basic way as being something it is like for someone to undergo. In the paper it is argued that when this slogan is examined it is in some respects trivial and in others mistaken. It is concluded that the slogan should be abandoned.

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)

In this book, William Lycan reviews the diverse philosophical views on consciousness--including those of Kripke, Block, Campbell, Sellars, and Casteneda--and ..

Is there an explanatory gap between raw feels and raw material? Some philosophers argue, and many other people believe, that scientific explanations of conscious experience cannot be as satisfying as typical scientific explanations elsewhere, even in our wildest dreams. The underlying philosophical claims are.

It is common parlance among philosophers who inquire into the nature of consciousness to speak of there being something it is like for the subject of a mental state to be in it. The popularity of the ‘what-it-is-like’ phrase stems, in part, from the assumption that it enables us to distinguish, in an intuitive and illuminating way, between conscious and unconscious mental states: conscious mental states, unlike unconscious mental states, are such that there is something it is like for their (...) subjects to be in them. The ‘what-it-is-like’ phrase, however, has not gone unopposed; some very clever philosophers have vigorously disputed it. Peter Hacker, for example, has argued that the phrase should be abandoned because it is ungrammatical, and Paul Snowdon has argued that it should be abandoned because the propositions expressed by its usage are either trivial or false. This paper mounts a case for the claim that neither of these conclusions is warranted. Against Hacker, it is argued that the arguments he produces for the ungrammaticality of the phrase are unpersuasive, and against Snowdon it is argued that he fails to consider a plausible and independently motivated interpretation of the phrase, and that, on this interpretation, the propositions expressed by its usage are non-trivially true.

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.

I discuss the meaning of 'There's something e is like', in the context of a reply to Eric Lormand's 'The explanatory stopgap'. I argue that Lormand is wrong to think it has a specially perceptual meaning. Rather, it has one of at least four candidate meanings: e is some way as regards its subject; e is some way and e's being that way is in the possession of its subject; e is some way in the awareness of its subject; e's (...) subject is the "experiencer" of e. I provide additional argumentation for the view in this paper that in the context, 'like this' functions as a predicate variable. (shrink)

The concept of consciousness has been the source of much philosophical, cognitive scientific and neuroscientific discussion for the past two decades. Many scientists, as well as philosophers, argue that at the moment we are almost completely in the dark about the nature of consciousness. Stuart Sutherland, in a much quoted remark, wrote that.

Recent work on consciousness has featured a number of debates on the existence and character of controversial types of phenomenal experience. Perhaps the best-known is the debate over the existence of a sui generis, irreducible cognitive phenomenology – a phenomenology proper to thought. Another concerns the existence of a sui generis phenomenology of agency. Such debates bring up a more general question: how many types of sui generis, irreducible, basic, primitive phenomenology do we have to posit to just be able (...) to describe the stream of consciousness? This book offers a first general attempt to answer this question in contemporary philosophy. It develops a unified framework for systematically addressing this question and applies it to six controversial types of phenomenal experience, namely, those associated with thought and judgment, will and agency, pure apprehension, emotion, moral thought and experience, and the experience of freedom.

In which a scientist searches for an empirical explanation for phenomenal experience, spurred by his instinctual belief that life is meaningful. What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. This engaging book--part scientific overview, part memoir, part futurist speculation--describes (...) Koch's search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest--his instinctual belief that life is meaningful. Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action. Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work--to uncover the roots of consciousness. (shrink)

Which objects and properties are represented in perceptual experience, and how are we able to determine this? The papers in this collection address these questions together with other fundamental questions about the nature of perceptual content. The book draws together papers by leading international philosophers of mind, including Alex Byrne (MIT), Alva Noë (University of California, Berkeley), Tim Bayne (St Catherine’s College, Oxford), Michael Tye (University of Texas, Austin), Richard Price (All Souls College, Oxford) and Susanna Siegel (Harvard University) Essays (...) address the central questions surrounding the content of perceptual experience Investigates how are we able to determine the admissible contents of experience Published in association with the journal Philosophical Quarterly .

Does thought have distinctive experiential features? Is there, in addition to sensory phenomenology, a kind of cognitive phenomenology--phenomenology of a cognitive or conceptual character? Leading philosophers of mind debate whether conscious thought has cognitive phenomenology and whether it is part of conscious perception and conscious emotion.

What is consciousness? How does the subjective character of consciousness fit into an objective world? How can there be a science of consciousness? In this sequel to his groundbreaking and controversial The Conscious Mind, David Chalmers develops a unified framework that addresses these questions and many others. Starting with a statement of the "hard problem" of consciousness, Chalmers builds a positive framework for the science of consciousness and a nonreductive vision of the metaphysics of consciousness. He replies to many critics (...) of The Conscious Mind, and then develops a positive theory in new directions. The book includes original accounts of how we think and know about consciousness, of the unity of consciousness, and of how consciousness relates to the external world. Along the way, Chalmers develops many provocative ideas: the " consciousness meter", the Garden of Eden as a model of perceptual experience, and The Matrix as a guide to the deepest philosophical problems about consciousness and the external world. This book will be required reading for anyone interested in the problems of mind, brain, consciousness, and reality. (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.

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.

I argue on linguistic grounds that when Mary comes to know what it's like to see a red thing, she comes to know a certain inexpressible truth about the character of her own experience. This affords a "no concept" reply to the knowledge argument. The reason the Knowledge Argument has proven so intractable may be that we believe that an inexpressible concept and an expressible concept cannot have the same referent.

Mary is confined to a black-and-white room, is educated through black-and-white books and through lectures relayed on black-and white television. In this way she learns everything there is to know about the physical nature of the world. She knows all the physical facts about us and our environment, in a wide sense of 'physical' which includes everything in completed physics, chemistry, and neurophysiology, and all there is to know about the causal and relational facts consequent upon all this, including of (...) course functional roles. If physicalism is true, she knows all there is to know. For to suppose otherwise is to suppose that there is more to know than every physical fact, and that is just what physicalism denies. … It seems, however, that Mary does not know all there is to know. For when she is let out of the black-and- white room or given a color television, she will learn what it is like to see something red, say. This is rightly described as learning—she will not say “ho, hum.” Hence, physicalism is false. (Jackson 1986, p. 291, Chapter 2, this volume). (shrink)

The terminology surrounding the dispute between higher-order and first-order theories of consciousness is piled so high that it sometimes obscures the view. When the debris is cleared away, there is a real prospect.
