835Philosophical issues about consciousnessIn L. Nadel (ed.), Encyclopedia of Cognitive Science, Nature Publishing Group. 2003.There are a number of different matters that come under the heading of ‘consciousness’. One of them is phenomenality, the feeling of say a sensation of red or a pain, that is what it is like to have such a sensation or other experience. Another is reflection on phenomenality. Imagine two infants, both of which have pain, but only one of which has a thought about that pain. Both would have phenomenal states, but only the latter would have a state of reflexive consciousness. This entry will start …Read more

497If perception is probabilistic, why doesn't it seem probabilistic?Philosophical Transactions of the Royal Society B 373 (1755). 2018.The success of the Bayesian approach to perception suggests probabilistic perceptual representations. But if perceptual representation is probabilistic, why doesn't normal conscious perception reflect the full probability distributions that the probabilistic point of view endorses? For example, neurons in MT/V5 that respond to the direction of motion are broadly tuned: a patch of cortex that is tuned to vertical motion also responds to horizontal motion, but when we see vertical motion, foveal…Read more

467Is experiencing just representing? (review)Philosophy and Phenomenological Research 58 (3): 663-670. 1998.The first problem concerns the famous Swampman who comes into existence as a result of a cosmic accident in which particles from the swamp come together, forming a molecular duplicate of a typical human. Reasonable people can disagree on whether Swampman has intentional contents. Suppose that Swampman marries Swampwoman and they have children. Reasonable people will be inclined to agree that there is something it is like for Swampchild when "words" go through his mind or come out of his mouth. F…Read more

397Measuring away an attentional confound?Neuroscience of Consciousness 3 (1): 1-3. 2017.A recent fMRI study by Webb et al. (Cortical networks involved in visual awareness independent of visual attention, Proc Natl Acad Sci U S A 2016;113:13923–28) proposes a new method for finding the neural correlates of awareness by matching atten- tion across awareness conditions. The experimental design, however, seems at odds with known features of attention. We highlight logical and methodological points that are critical when trying to disentangle attention and awareness.

1041Comparing the major theories of consciousnessIn Michael Gazzaniga (ed.), The Cognitive Neurosciences IV, . pp. 1111-1123. 2009.This article compares the three frameworks for theories of consciousness that are taken most seriously by neuroscientists, the view that consciousness is a biological state of the brain, the global workspace perspective and an account in terms of higher order states. The comparison features the “explanatory gap” (Nagel, 1974; Levine, 1983) the fact that we have no idea why the neural basis of an experience is the neural basis of that experience rather than another experience or no experience at …Read more

325Bodily sensations as an obstacle for representationismIn Murat Aydede (ed.), Pain: New Essays on its Nature and the Methodology of its Study, Bradford Book/mit Press. pp. 137-142. 2005.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 r…Read more

284How not to find the neural correlate of consciousnessIn João Branquinho (ed.), The Foundations of Cognitive Science, Oxford: Clarendon Press. pp. 1. 2001.There are two concepts of consciousness that are easy to confuse with one another, access-consciousness and phenomenal consciousness. However, just as the concepts of water and H2O are different concepts of the same thing, so the two concepts of consciousness may come to the same thing in the brain. The focus of this paper is on the problems that arise when these two concepts of consciousness are conflated. I will argue that John Searles reasoning about the function of consciousness goes wrong …Read more

156Semantics, conceptual roleIn [Book Chapter] (Unpublished), Routledge. pp. 242--256. 1997.According to Conceptual Role Semantics ("CRS"), the meaning of a representation is the role of that representation in the cognitive life of the agent, e.g. in perception, thought and decision-making. It is an extension of the well known "use" theory of meaning, according to which the meaning of a word is its use in communication and more generally, in social interaction. CRS supplements external use by including the role of a symbol inside a computer or a brain. The uses appealed to are not just…Read more

598Wittgenstein and QualiaPhilosophical Perspectives 21 (1): 73-115. 2007.endorsed one kind of inverted spectrum hypothesis and rejected another. This paper argues that the kind of inverted spectrum hypothesis that Wittgenstein endorsed is the thin end of the wedge that precludes a Wittgensteinian critique of the kind of inverted spectrum hypothesis he rejected. The danger of the dangerous kind is that it provides an argument for qualia, where qualia are contents of experiential states which cannot be fully captured in natural language. I will pinpoint the difference …Read more

99Ridiculing social constructivism about phenomenal consciousnessBehavioral and Brain Sciences 22 (1): 199-201. 1999.Money is a cultural construction, leukemia is not. In which category does phenomenal consciousness fit? The issue is clarified by a distinction between what cultural phenomena causally influence and what culture constitutes. Culture affects phenomenal consciousness but it is ridiculous to suppose that culture constitutes it, even in part.

198The photographic fallacy in the debate about mental imageryNoûs 17 (4): 651-62. 1983.There has been considerable debate among philosophers and psychol- ogists about whether the internal representations of imagery represent in the manner of pictures or in the manner of language. One side, pictorialism,holds that an internal imagery representation of Reagan is like a picture of Reagan. The other side, descriptionalism,holds that an internal imagery representation of Reagan is more like a string of words denoting or describing Reagan. My aim here is to expose a widespread fallacy o…Read more

631The higher order approach to consciousness is defunctAnalysis 71 (3). 2011.The higher order approach to consciousness attempts to build a theory of consciousness from the insight that a conscious state is one that the subject is conscious of. There is a well-known objection1 to the higher order approach, a version of which is fatal. Proponents of the higher order approach have realized that the objection is significant. They have dealt with it via what David Rosenthal calls a “retreat” (2005b, p. 179) but that retreat fails to solve the problem.

1287Consciousness and accessibilityBehavioral and Brain Sciences 13 (4): 596-598. 1990.This is my first publication of the distinction between phenomenal consciousness and access consciousness, though not using quite those terms. It ends with this: "The upshot is this: If Searle is using the access sense of "consciousness," his argument doesn't get to first base. If, as is more likely, he intends the what-it-is-like sense, his argument depends on assumptions about issues that the cognitivist is bound to regard as deeply unsettled empirical questions." Searle replies: "He refers …Read more

667Anti-Reductionism Slaps BackNoûs 31 (s11): 107-132. 1997.For nearly thirty years, there has been a consensus (at least in English-speaking countries) that reductionism is a mistake and that there are autonomous special sciences. This consensus has been based on an argument from multiple realizability. But Jaegwon Kim has argued persuasively that the multiple realizability argument is flawed.1 I will sketch the recent history of the debate, arguing that much --but not all--of the anti-reductionist consensus survives Kim's critique. This paper was origi…Read more
