The knowledge argument aims to refute physicalism, the view that the world is entirely physical. The argument first establishes the existence of facts about consciousness that are not a priori deducible from the complete physical truth, and then infers the falsity of physicalism from this lack of deducibility. Frank Jackson gave the argument its classic formulation. But now he rejects the argument . On his view, it relies on a false conception of sensory experience, which should be replaced with representationalism (...) , the view that phenomenal states are just representational states. And he argues that mental representation is physically explicable. (shrink)

Consider the conscious states of a single subject at a time. Arguably, split-brain cases show that such states need not be jointly accessible. It is less clear that these cases also show that such states need not be jointly experienced. Michael Tye (2004) argues split-brain cases do have that implication, and Timothy Bayne and David Chalmers (2003) argue that they do not. I will develop two objections to Tye’s arguments. First, an analogy to blindsight on which he relies is questionable. (...) Second, even if his analogy succeeds, it shows only that a single person can simultaneously have two separate sets of phenomenally conscious mental states. That result fails to undermine the phenomenalunity thesis that Bayne and Chalmers defend, on which phenomenal consciousness is necessarily unified. (shrink)

Ideal for courses in consciousness and the philosophy of mind, Consciousness and The Mind-Body Problem: A Reader presents thirty-three classic and contemporary readings, organized into five sections that cover the major issues in this debate: the challenge for physicalism, physicalist responses, alternative responses, the significance of ignorance, and mental causation. Edited by Torin Alter and Robert J. Howell, the volume features work from such leading figures as Karen Bennett, Ned Block, David J. Chalmers, Frank Jackson, Colin McGinn, David Papineau, and (...) many others. (shrink)

Does synesthesia undermine representationalism? Gregg Rosenberg (2004) argues that it does. On his view, synesthesia illustrates how phenomenal properties can vary independently of representational properties. So, for example, he argues that sound/color synesthetic experiences show that visual experiences do not always represent spatial properties. I will argue that the representationalist can plausibly answer Rosenberg.

: Phenomenal knowledge usually comes from experience. But it need not. For example, one could know what it’s like to see red without seeing red—indeed, without having any color experiences. Daniel Dennett (2007) and Pete Mandik (forthcoming) argue that this and related considerations undermine the knowledge argument against physicalism. If they are right, then this is not only a problem for anti‐physicalists. Their argument threatens to undermine any version of phenomenal realism— the view that there are phenomenal properties, or qualia, (...) that are not conceptually reducible to physical or functional properties. I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. This will strengthen the case for physically and functionally irreducible qualia. 2 Phenomenal knowledge usually comes from experience. For example, I know what it’s like to see red because I have done so. Does knowing what it’s like to have an experience with phenomenal character X require having an experience with X? No. A famous counterexample is Hume’s missing shade of blue, in which one can extrapolate from phenomenally similar experiences (A Treatise of Human Nature, Bk. I, Pt. I, Sec. I).1 One might think that a weaker version of the no‐phenomenal‐knowledge‐without‐experience thesis remains tenable, e.g., that knowing what it’s like to see in color requires having or having had color experiences. But this thesis also seems doubtful. Peter Unger (1966) devised plausible counterexamples over four decades ago, and since then others (e.g., Lewis 1988, Alter 1998, Stoljar 2005) have done the same. One could have phenomenal knowledge of color experiences without having such experiences. Indeed, one could have such knowledge without having experiences that are remotely like color experiences. What is the significance of this observation for contemporary debates about consciousness and physicalism? Daniel Dennett (2007) and Pete Mandik (forthcoming) suggest that it undermines the knowledge argument against physicalism.2 That is because they take the claim that someone who has never seen in color could not know what it’s like to see in color to be the basis of the knowledge argument’s main epistemic premise: the premise that (roughly put) 3 no amount of physical knowledge is sufficient for phenomenal knowledge of color experiences. If they are right, then this is not only a problem for anti‐ physicalists. Many physicalists (e.g., Loar 1990/97, Papineau 2002, 2007) accept the knowledge argument’s epistemic premise. Dennett’s and Mandik’s arguments threaten all versions of what David Chalmers (2003) calls phenomenal realism, the view that there are phenomenal properties, or qualia, that are not conceptually reducible to physical or functional properties.3 I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. The net result will be to strengthen the case for physically inexplicable qualia. (shrink)

As I type these words, cognitive systems in my brain engage in visual and auditory information processing. This processing is accompanied by subjective states of consciousness, such as the auditory experience of hearing the tap-tap-tap of the keyboard and the visual experience of seeing the letters appear on the screen. How does the brain's activity generate such experiences? Why should it be accompanied by conscious experience in the first place? This is the hard problem of consciousness.

Kulvicki’s goal is to give a representationalist account of what it’s like to see a property that is “fully externalist about perceptual representation” (p. 1) and yet accommodates a certain “internalist intuition” (p. 4), which he describes as follows: “something about what it is like to see a property is internally determined, dependent only on the way one is built from the skin in” (p. 3). He illustrates this intuition with an inverted spectrum case and the manifest-image problem. On his (...) view, there’s an apparent conflict between the intuition and representationalism. That’s because, on representationalism, “what it is like to see a shade of color can be exhaustively explained in terms of what is perceptually represented” (p. 1) and, he claims, “all representational facts are externally determined” (p. 4). In short, if what it’s like is partly internally determined, then how can it be fully explained in terms of externally determined representational facts? (shrink)

This paper examines the way Charles Darwin applied his domestic breeding analogy to the practical workings of species evolution: that application, it is argued, centered on Darwin's distinction between methodical and unconscious selection. Methodical selection, which entailed pairing particular individuals for mating purposes, represented conditions of strict geographic isolation, obviously useful for species multiplication (speciation). By contrast, unconscious selection represented an open landmass with a large breeding population. Yet Darwin held that this latter scenario, which often would include multiple ecological (...) subdistricts and thus partial isolation, was better suited for speciation than were isolated conditions. At the same time, many passages in Darwin's writings that apparently portrayed phyletic evolution exclusively (these including references to unconscious selection), actually applied to speciation as well, for phyletic change in a single district could constitute a local manifestation of a larger common-descent pattern. This generic use of "phyletic" change was reflected in Darwin's deployment of the unconscious selection analogy in his published writings as well as in his dispute with Moritz Wagner over the necessity of geographic isolation for speciation. We can thus understand Darwin's otherwise puzzling declaration in The Origin of Species that unconscious selection was 'more important' than the methodical approach. (shrink)

This volume presents thirteen new essays on phenomenal concepts and phenomenal knowledge: twelve by philosophers and one by a scientist. In this introduction, we provide some background and summarize the essays.

The startling empirical data that concern us here are well known. Severing the corpus callosum produces a kind of mental bifurcation (Sperry 1968). In one experiment, a garlic smell is presented to a patient.

Russellian monism offers a distinctive perspective on the relationship between the physical and the phenomenal. For example, on one version of the view, phenomenal properties are the categorical bases of fundamental physical properties, such as mass and charge, which are dispositional. Russellian monism has prominent supporters, such as Bertrand Russell, Grover Maxwell, Michael Lockwood, and David Chalmers. But its strengths and shortcomings are often misunderstood. In this paper we try to eliminate confusions about the view and defend it from criticisms. (...) We present its core and distinguish different versions of it. We then compare these versions with traditional theories, such as physicalism, dualism, and idealism. We also argue that the knowledge argument and the conceivability argument are consistent with Russellian monism and that existing arguments against the view, such as the argument from weirdness, are not decisive. We conclude that Russellian monism is an attractive view that deserves serious consideration. (shrink)
