In 1986, I argued that pains are essentially not phenomenal states. Using a Wittgen-steinian son of argument, I showed that the same sort of phenomena can be had on different occasions, and on one occasion persons be in pain, while on another occasion persons not be in pain. I also showed that very different phenomena could be experienced and, yet, organisms have the same sort of pain. I supported my arguments with empirical data from both laboratory and clinical studies. There (...) is nothing about this thesis I would now retract. However, there was a further thesis that needs to be reconsidered. I argued that phenomenal states are only accompaniments of pains, that pains are essentially a combination of cognitive, affective and behavioural/motivational states. This thesis I do now zaish to retract. I now argue that phenomenal states are necessary for pains, but still not sufficient. There must also be a cognitive state which involves an evaluation of the phenomenon as something like, 'Harm to the body'. The evaluation is a kind of de re belief, regarding the phenomenon as itself representing harm to the body. Besides admitting that phenomenal states are necessary for pains, I also now claim that other relevant belief states, affective states, and behavioural/motivational states are not necessary for pain, but normal consequences of pain. This revised theory is preferable to the 1986 one because it fits better with empirical facts (including providing better explanations for anomalous cases), fits better with certain powerful common-sense intuitions, and fits better with a larger theory of consciousness I have been developing. Among other things, it turns out that being in pain is a quite peculiar conscious state and considering it as a paradigm for consciousness is a serious mistake. (shrink)

Abstract: “Consciousness” seems to be a polysemic, ambiguous, term. Because of this, theorists have sought to distinguish the different kinds of phenomena that “consciousness” denotes, leading to a proliferation of terms for different kinds of consciousness. However, some philosophers—univocalists about consciousness—argue that “consciousness” is not polysemic or ambiguous. By drawing upon the history of philosophy and psychology, and some resources from semantic theory, univocalism about consciousness is shown to be implausible. This finding is important, for if we accept the univocalist (...) account then we are less likely to subject our thought and talk about the mind to the kind of critical analysis that it needs. The exploration of the semantics of “consciousness” offered here, by way of contrast, clarifies and fine-tunes our thought and talk about consciousness and conscious mentality and explains why “consciousness” means what it does, and why it means a number of different, but related, things.

Searle (1990) argues that unconscious intrinsic intentional states must be accessible to consciousness because (1) all intrinsic intentional states have aspectual shape, the of which cannot be explained in a third-person (e.g., neurophysiological) vocabulary, and (2) ontologically, unconscious mental states are neurophysiological processes. This argument confuses three senses of namely, factuality, individuative properties, and phenomenological presence.

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.

To make progress on the problem of consciousness, we have to confront it directly. In this paper, I first isolate the truly hard part of the problem, separating it from more tractable parts and giving an account of why it is so difficult to explain. I critique some recent work that uses reductive methods to address consciousness, and argue that such methods inevitably fail to come to grips with the hardest part of the problem. Once this failure is recognized, the (...) door to further progress is opened. In the second half of the paper, I argue that if we move to a new kind of nonreductive explanation, a naturalistic account of consciousness can be given. I put forward my own candidate for such an account: a nonreductive theory based on principles of structural coherence and organizational invariance, and a double-aspect theory of information.

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

This paper is an edited transcription of a talk at the 1997 Montreal symposium on "Consciousness at the Frontiers of Neuroscience". There's not much here that isn't said elsewhere, e.g. in "Facing Up to the Problem of Consciousness" and "How Can We Construct a Science of Consciousness?"]].
