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)

Consciousness in the Physical World collects historical selections, recent classics, and new pieces on Russellian monism, a unique alternative to the physicalist and dualist approaches to the problem of consciousness.

What is the nature of consciousness? How is consciousness related to brain processes? This volume collects thirteen new papers on these topics: twelve by leading and respected philosophers and one by a leading color-vision scientist. All focus on consciousness in the "phenomenal" sense: on what it's like to have an experience. Consciousness has long been regarded as the biggest stumbling block for physicalism, the view that the mind is physical. The controversy has gained focus over the last few decades, and (...) phenomenal knowledge and phenomenal concepts--knowledge of consciousness and the associated concepts--have come to play increasingly prominent roles in this debate. Consider Frank Jackson's famous case of Mary, the super-scientist who learns all the physical information while confined in a black-and-white room. According to Jackson, if physicalism is true, then Mary's physical knowledge should allow her to deduce what it's like to see in color. Yet it seems intuitively clear that she learns something when she leaves the room. But then how can consciousness be physical? Arguably, whether this sort of reasoning is sound depends on how phenomenal concepts and phenomenal knowledge are construed. For example, some argue that the Mary case reveals something about phenomenal concepts but has no implications for the nature of consciousness itself. Are responses along these lines adequate? Or does the problem arise again at the level of phenomenal concepts? The papers in this volume engage with the latest developments in this debate. The authors' perspectives range widely. For example, Daniel Dennett argues that anti-physicalist arguments such as the knowledge argument are simply confused; David Papineau grants that such arguments at least reveal important features of phenomenal concepts; and David Chalmers defends the anti-physicalist arguments, arguing that the "phenomenal concept strategy" cannot succeed.

According to social externalism, it is possible to possess a concept not solely in virtue of one’s intrinsic properties but also in virtue of relations to one’s linguistic community. Derek Ball (2009) argues, in effect, that (i) social externalism extends to our concepts of colour experience and (ii) this fact undermines both the knowledge argument against physicalism and the most popular physicalist response to it, known as the phenomenal concept strategy. I argue that Ball is mistaken about (ii) even granting (...) (i). The knowledge argument and the phenomenal concept strategy might have to be modified to make them consistent with social externalism, but not in fundamental or detrimental ways. (shrink)

Mary learns all the physical facts that one can learn by watching lectures on black-on-white television. According to Jackson, Mary learns new facts when she leaves the room and has color experiences, and that this undermines physicalism. Physicalists have responded by denying the new facts thesis; they argue, she acquires abilities, acquaintance knowledge, or new guises. I argue that the NFT is more plausible than any of the proposed alternatives. I also argue that the NFT does not undermine physicalism unless (...) physicalism entails that all physical facts are discursively learnable, and that the latter entailment is questionable. (shrink)

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?

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)

: 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)

Some argue that God’s omnipotence and moral perfection prevent God from being afraid and having evil desires and thus from understanding such states—which contradicts God’s omniscience. But, I argue, God could acquire such understanding indirectly, either by (i) perceiving the mental states of imperfect creatures, (ii) imaginatively combining the components of mental states with which God could be acquainted, or (iii) having false memory traces of such states. (i)–(iii) are consistent with the principal divine attributes.

‘Free action’ is subject to the causal theory of reference and thus that The essential nature of free actions can be discovered only by empirical investigation, not by conceptual analysis. Heller ’s proposal, if true, would have significant philosophical implications. Consider the enduring issue we will call the Compatibility Issue : whether the thesis of determinism is logically compatible with the claim that.

Many philosophers accept the conceivability of zombies: creatures that lack consciousness but are physically and functionally identical to conscious human beings. Many also believe that the conceivability of zombies supports their metaphysical possibility. And most agree that if zombies are metaphysically possible, then physicalism is false. So, the claim that zombies are conceivable may have considerable significance. 1.

Do I have a special reason to care about my future, as opposed to yours? We reject the common belief that I do. Putting our thesis paradoxically, we say that nothing matters in survival: nothing in our continued existence justifies any special self-concern. Such an "extreme" view is standardly tied to ideas about the metaphysics of persons, but not by us. After rejecting various arguments against our thesis, we conclude that simplicity decides in its favor. Throughout the essay we honor (...) Jim Rachels, whose final days exemplified his own unselfish morality as well as the “neutralist” ideal we espouse. As an appendix, we include the last original work to be published by James Rachels, in which he criticizes Sidgwick’s most famous defense of egoism. (shrink)

Zombies make trouble for physicalism. Intuitively, they seem conceivable, and many take this to support their metaphysical possibility – a result that, most agree, would refute physicalism. John Hawthorne (2002) [Philosophical Studies 109, 17–52] and David Braddon-Mitchell (2003) [The Journal of Philosophy 100, 111–135] have developed a novel response to this argument: phenomenal concepts have a conditional structure – they refer to non-physical states if such states exist and otherwise to physical states – and this explains the zombie intuition. I (...) argue that this strategy fails. The considerations Hawthorne and Braddon-Mitchell adduce in support of their analysis in fact do no such thing. Further, their main argument for the analysis is self-defeating: exactly similar reasoning would undermine the view it is meant to establish. Finally, on closer inspection the conditional analysis is incompatible with the zombie intuition. Thus, not only is the analysis incapable of explaining the intuition: the intuition’s plausibility indicates that the analysis is incorrect. I also suggest that the allure of the conditional-analysis strategy may derive from a questionable view about what explaining the intuition would require. (shrink)

A Dialogue on Consciousness introduces readers to the debate about consciousness and physicalism, starting with its origins in Descartes, through a lively and entertaining dialogue between unemployed graduate students, who, secretly living in a university library, discuss major theories and quote passages from classic and contemporary texts in search of an answer.

Frank Jackson first presented the Knowledge Argument in "Epiphenomenal Qualia" 1982). The KA is an argument against physicalism, the doctrine that everything is physical. The general thrust of the KA is that physicalism errs by misconstruing or denying the existence of the subjective features of experience. Physicalists have given numerous responses, and the debate continues about whether the KA ultimately succeeds in refuting any or all forms of physicalism. Jackson himself has recently.

Some argue that split-brain cases undermine the thesis that phenomenal consciousness is necessarily unified. This paper defends the phenomenal unity thesis against Michael Tye's (2003 ) version of that argument. Two problems are identified. First, his argument relies on a questionable analysis of the split-brain data. Second, his analysis leads to the view that in experimental situations split-brain patients are not single subjects – a result that would render the analysis harmless to the phenomenal unity thesis.

In "What is it Like to be a Bat?" Thomas Nagel argues that we cannot imagine what it is like to be a bat or presently understand how physicalism might be true. Both arguments have been seriously misunderstood. I defend them against various objections, point out a problem with the argument against physicalism, and show how the problem can be solved.

I wish to consider an objection to Frank Jackson's knowledge argument recently made by Derk Pereboom.

The Confederate Battle Flag (CBF) is in the news again. On January 16th, 2000, 46,000 people came to Columbia, South Carolina, to protest its display over the state’s capital dome. On July 1st, the CBF was removed. But on the same day, it was raised in front of the Statehouse steps. The controversy has received a great deal of media coverage and was a factor in the 2000 presidential primaries. CBF displays raise a philosophical question I wish to address: What (...) determines whether a symbol or symbol-display is racist? I will focus on the CBF because of its contemporary relevance. But the discussion will shed light on the general issue of when a symbol or symbol-display has a particular meaning and when it does not. (shrink)

Derek Parfit's combined-spectrum argument seems to conflict with epistemicism, a viable theory of vagueness. While Parfit argues for the indeterminacy of personhood, epistemicism denies indeterminacy. But, we argue, the linguistically based determinacy that epistemicism supports lacks the sort of normative or ontological significance that concerns Parfit. Thus, we reformulate his argument to make it consistent with epistemicism. We also dispute Roy Sorensen's suggestion that Parfit's argument relies on an assumption that fuels resistance to epistemicism, namely, that 'the magnitude of a (...) modification must be proportional to its effect.'.

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.

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)

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)

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.

Physicalism should be characterized in a way that makes it compatible with the possibility that the physical world is infinitely decomposable. Some have proposed solving this problem by replacing a widely accepted No Fundamental Mentality requirement on physicalism with a more general No Low-Level Mentality requirement. The latter states that physicalism could be true if there is a level of decomposition beneath which nothing is mental, whereas physicalism is false otherwise. Brown argues that this solution does not work. He devises (...) an infinitely decomposable possible world in which physicalism should come out as true even though there is mentality all the way down. I propose a solution that circumvents his argument. The key is to specify the sort of mentality that physicalism cannot abide at any level, namely, mentality that does not consist solely in a structural-dynamic arrangement of entities. I also argue that the problem Brown identifies has significant implications for what is at stake in the debate over physicalism’s truth or falsity—implications he undersells. (shrink)

In The Nature of Consciousness, Mark Rowlands argues that phenomenal properties, which constitute what it is like to have a conscious experience, are “transcendental”: that they are properties by which we are conscious of the nonphenomenal world, but they are not objects of conscious awareness or even linguistic reference. He uses that conclusion to support a mysterian position on the explanatory-gap problem: that it is impossible to understand how phenomenal consciousness arises from physical systems such as the brain.

The titular ‘Mary’ refers to Jackson’s famous protagonist. Her story takes place in the future, when all physical facts have been discovered. This includes “everything in completed physics, chemistry, and neurophysiology, and all there is to know about the causal and relational facts consequent upon all this, including of course functional roles” . Mary learns all this by watching lectures on a monochromatic television monitor. But she spends her life in a black-and-white room and has no color experiences. Then she (...) leaves the room and sees colors for the first time. (shrink)

According to Russellian monism, phenomenal consciousness is constituted by inscrutables: intrinsic properties that categorically ground dispositional properties described by fundamental physics. On Russellian physicalism, those inscrutables are construed as protophenomenal properties: non-structural properties that both categorically ground dispositional properties and, perhaps when appropriately structured, collectively constitute phenomenal properties. Morris and Brown argue that protophenomenal properties cannot serve this purpose, given assumptions Russellian monists typically make about the modal profile of such properties. Those assumptions, it is argued, entail that protophenomenal properties (...) are ‘experience specific’, that is, they are individuated by their potential to constitute phenomenal properties, and are thus not genuinely physical. However, we argue, that reasoning assumes that physical inscrutables must be individuated in terms of their grounding roles. Not only is that assumption questionable: it is antithetical to Russellian monism. (shrink)

A symbol might have racist connotations in the sense that a substantial portion of the relevant population associates it with racist values or institutions. A governmental symbol display might therefore carry racist connotations that the government doesn’t intend, including connotations that haven’t always been attached to the symbol. So I claimed recently in the pages of this journal (Alter 2000b). I also explained how those claims create problems for some of George Schedler’s (1998) main views about governmental displays of the (...) Confederate battle flag. In his response, Schedler rejects my claims, arguing that they lead to absurdities when applied to various examples. He adds that one of his examples brings into question my “political savvy” (Schedler 2000, p. 5). Be that as it may, his arguments against my claims are entirely without force, and serve to confirm the weakness of his initial position. So I’ll argue. I’ll also identify a problematic assumption in our dispute, which is not uncommon in discussions of symbolic meaning and racist speech. (shrink)

Sawyer characterizes the zombie intuition as the claim that zombies are metaphysically possible. That’s not what I mean by the phrase. On my usage, ‘the zombie intuition’ refers to a conceivability claim: the claim that there’s no a priori incoherence in the hypothesis of a minimal physical/functional duplicate of the actual world but without consciousness, i.e., that PT&~Q is conceivable. The claim is the first step of a two-step argument, the second step of which is to infer the corresponding metaphysical (...) possibility. The inference is controversial, but that’s not my concern here. By ‘the zombie intuition’, I mean the first step, which is a claim of conceivability, not metaphysical possibility. (shrink)

The God Dialogues is an intriguing and extensive philosophical debate about the existence of God.

The God Dialogues is an intriguing and extensive philosophical debate about the existence of God. Engaging and accessible, it covers all the main arguments for and against God's existence, from traditional philosophical "proofs" to arguments that involve the latest developments in biology and physics. Three main characters represent the principal views: Theodore Logan, the theist; Eva Lucien, the atheist; and Gene Sesquois, the agnostic. Their debate takes place during a post-college cross-country road trip during which Gene expresses dismay over his (...) future. He wants to do something meaningful with his life but is at a loss as to how to proceed, despite having just earned a degree in engineering. Gene's quandary precipitates a discussion of the meaning of life and its connection to God's existence. This in turn leads to vigorous debates about morality and theism, evidence for and against God's existence, probability and the rationality of belief, and the relationship between faith and reason. The strongest arguments from all three perspectives are fairly represented. An annotated list of suggested readings directs readers to relevant and helpful primary sources.Assuming no background knowledge, The God Dialogues is ideal for courses in the philosophy of religion, an excellent supplement for introduction to philosophy courses, and a compelling introduction for anyone with an interest in the subject.

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.
