Many philosophers believe that there is a fundamental distinction between knowing that something is the case and knowing how to do something. According to Gilbert Ryle, to whom the insight is credited, knowledge-how is an ability, which is in turn a complex of dispositions. Knowledge-that, on the other hand, is not an ability, or anything similar. Rather, knowledge-that is a relation between a thinker and a true proposition.

Language and Problems of Knowledge is sixteenth in the series Current Studies in Linguistics, edited by Jay Keyser.

I hear the patter of little feet around the house, I expect Bruce. What I expect is a cat, a particular cat. If I heard such a patter in another house, I might expect a cat but no particular cat. What I expect then seems to be a Meinongian incomplete cat. I expect winter, expect stormy weather, expect to shovel snow, expect fatigue---a season, a phenomenon, an activity, a state. I expect that someday mankind will inhabit at least five planets. (...) This time what I expect is a state of affairs. If we let surface grammar be our guide, the objects of expectation seem quite a miscellany. The same goes for belief, since expectation is one kind of belief. The same goes for desire: I could want Bruce, want a cat but no particular cat, want winter, want stormy weather, want to shovel snow, want fatigue, or want that someday mankind will inhabit at least five planets. The same goes for other attitudes to the extent that they consist partly of beliefs or desires or lacks thereof. But the seeming diversity of objects might be an illusion. Perhaps the objects of attitudes are uniform in category, and it is our ways of speaking elliptically about these uniform objects that are diverse. That indeed is our consensus. We mostly think that the attitudes uniformly have propositions as their objects. That is why we speak habitually of "propositional attitudes.". (shrink)

This is a new release of the original 1949 edition.

David Lewis and Laurence Nemirow claim that knowing what an experience is like is knowing-how, not knowing-that. They identify this know-how with the abilities to remember, imagine, and recognize experiences, and Lewis labels their view ‘the Ability Hypothesis’. The Ability Hypothesis has intrinsic interest. But Lewis and Nemirow devised it specifically to block certain anti-physicalist arguments due to Thomas Nagel and Frank Jackson . Does it?

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

Lycan not only uses the numerous arguments against materialism, and functionalist theories of mind in particular, to gain a more detailed positive view of the ..

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

Much of the contemporary debate in the philosophy of mind is concerned with the clash between certain strongly held intuitions and what science tells us about the mind and its relation to the world. What science tells us about the mind points strongly towards some version or other of physicalism. The intuitions, in one way or another, suggest that there is something seriously incomplete about any purely physical story about the mind.

Oxford Handbooks offer authoritative and up-to-date surveys of original research in a particular subject area. Specially commissioned essays from leading figures in the discipline give critical examinations of the progress and direction of debates. Oxford Handbooks provide scholars and graduate students with compelling new perspectives upon a wide range of subjects in the humanities and social sciences. The Oxford Handbook of Contemporary Philosophy is the definitive guide to what's going on in this lively and fascinating subject. Jackson and Smith, themselves (...) two of the world's most eminent philosophers, have assembled more than thirty distinguished scholars to contribute incisive and up-to-date critical surveys of the principal areas of research. The coverage is broad, with sections devoted to moral philosophy, social and political philosophy, philosophy of mind and action, philosophy of language, metaphysics, epistemology, and philosophy of the sciences. This Handbook will be a rich source of insight and stimulation for philosophers, students of philosophy, and for people working in other disciplines of the humanities, social sciences, and sciences, who are interested in the state of philosophy today.

This book maintains that our conception of consciousness and cognition begins with and depends upon a few fundamental errors. Thau elucidates these errors by discussing three important philosophical puzzles - Spectrum Inversion, Frege's Puzzle, and Black-and-White Mary - each of which concerns some aspect of either consciousness or cognition. He argues that it has gone unnoticed that each of these puzzles presents the very same problem and, in bringing this commonality to light, the errors in our natural conception of consciousness (...) and cognition are also reviewed.

In a now famous thought experiment, Frank jackson asked us t0 imagine an omniscient scientist, Mary, who is coniincd in a black-and-white room and then released into the world 0f color . Assuming that she is omniscicnt in respect of all physical facts—roughiy, all the facts available to physics and all the facts that they in turn Hx or determine-physicalism would suggest that there is no new fact Mary can discover after emancipation; physicalism holds that all facts are physical in (...) the relevant sense . Yet we cannot help but feel that coming out of that room would be an occasion of dramatic enlightenment and, in particular, an occasion for learning facts to do with how red or yellow or blue 100ks or, as it is usually said, with what it is like t0 sec red or yellow or blue. Many in the black-and—whit<—: room knew all the physical facts about the world, where these may be taken to include three sorts of color facts: objcctual facts, as to what surface colors different objects have, assuming as I shall do throughout—that colors are properties of objects; intentional facts, as to which colors different objects 0r apparent objects are represented as having in the subjc-:ct’s experience, rightly or wrongly; and nonintentional facts, about what such color experiences are like in their effects on subiccts—wh<—:ther they are comforting, or arousing, or whatever. But, according to the argument, Mary didn’t know how any color looks or, equivalently, what color experience is like in itself, not just in its effects O1'1 subjects. This particular nonintentional fact about the quality of color c-zxpc-2ri<—:ncc-—this phenomenal fact, as it is often describcd—she did not. (shrink)

Michael Thau’s book challenges much of current orthodox theory about consciousness and cognition. It is an enormously stimulating tour de force. I highly recommend it.

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.

In this lucid, deep, and entertaining book, John Perry supposes that type-identity physicalism is antecedently plausible, and that rejecting this thesis requires good reason. He aims to show that experience gap arguments, as given by Jackson, Kripke, and Chalmers, fail to provide such reason, and moreover that each failure stems from an overly restrictive conception of the content of thought.
