Does phenomenal consciousness have a subjective character that physicalism cannot capture?","position":"There is something it is like to be a bat. There is something it is like to be each conscious creature, and the subjective character of conscious experience is what physicalism, in attempting to reduce or eliminate the mental, must miss. A physicalist account of bat neurology gives us, at most, knowledge of the objective character of the bat's brain states; what such an account cannot give us is what the bat's experience is like for the bat. The fact that we cannot know what bat-experience is like (because the bat's perceptual modalities are too different from ours) does not show that there is nothing there to be known; it shows that our objective methods cannot reach the subjective character of an experience whose perspective we do not share. The argument generalizes: phenomenal consciousness has a subjective character that is essentially perspectival, and the reduction-elimination-annexation strategies of physicalism cannot capture it. The bat thesis is not the claim that consciousness is non-physical in some Cartesian-dualist sense; it is the claim that physicalist methods, as currently understood, do not have the conceptual resources to handle the subjective character of experience. Future understanding will require a richer framework — one of the projects of Mind and Cosmos (2012) is to gesture at what such a framework might look like.","paragraphs":[[{"t":"There is something it is like to be a bat.","n":[]},{"t":"There is something it is like to be each conscious creature, and the subjective character of conscious experience is what physicalism, in attempting to reduce or eliminate the mental, must miss.","n":[1,2]},{"t":"A physicalist account of bat neurology gives us, at most, knowledge of the objective character of the bat's brain states; what such an account cannot give us is what the bat's experience is like for the bat.","n":[]}],[{"t":"The fact that we cannot know what bat-experience is like (because the bat's perceptual modalities are too different from ours) does not show that there is nothing there to be known; it shows that our objective methods cannot reach the subjective character of an experience whose perspective we do not share.","n":[]},{"t":"The argument generalizes: phenomenal consciousness has a subjective character that is essentially perspectival, and the reduction-elimination-annexation strategies of physicalism cannot capture it.","n":[]}],[{"t":"The bat thesis is not the claim that consciousness is non-physical in some Cartesian-dualist sense; it is the claim that physicalist methods, as currently understood, do not have the conceptual resources to handle the subjective character of experience.","n":[]},{"t":"Future understanding will require a richer framework — one of the projects of Mind and Cosmos (2012) is to gesture at what such a framework might look like.","n":[3,4,5]}]],"texts":"'What Is It Like to Be a Bat?'

Frank Jackson's 'Epiphenomenal Qualia' (1982) and the Mary's-room argument provide a parallel anti-physicalist case. David Chalmers's The Conscious Mind (1996) and 'Facing Up to the Problem of Consciousness' (1995) extend the bat thesis as the \"hard problem of consciousness.\" The eliminativist response (Dennett's Consciousness Explained, Churchland's eliminative materialism, the Quining-qualia tradition) treats the subjective character as an illusion to be eliminated. The debate is not settled; the field divides between those who treat phenomenal consciousness as a real explanandum that physicalism has not explained and those who treat it as a residual confusion.","era":"1937-present","discipline":"Philosophy","refs":[{"n":1,"work":"Mortal Questions","page":"pp. 180–181","canonical":"","quote":"There may be further* *implications about the form of the experience; there may even* *(though I doubt it] e implications about the behavior of the* *organism.
