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)

This book defends Frank Jackson’s knowledge argument against physicalism. According to physicalism, consciousness is a physical phenomenon. The knowledge argument stars Mary, who learns all objective, physical information through black-and-white media and yet acquires new information when she first sees colors for herself: information about what it is like to see in color. Based partly on that case, Jackson concludes that not all information is physical. The book argues that the knowledge argument succeeds in refuting all standard versions of physicalism: (...) versions on which consciousness is grounded by what objective science reveals. It also argues that given further, plausible assumptions, the knowledge argument leads to Russellian monism, on which there are intrinsic properties that both constitute consciousness and underlie properties physics describes, such as mass and charge. It explains how the knowledge argument establishes those two conclusions and defends the argument against numerous objections. (shrink)

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.

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.

Yoga has come to be an icon of Indian culture and civilization, and it is widely regarded as being timeless and unchanging. Based on extensive ethnographic research and an analysis of both ancient and modern texts, Yoga in Modern India challenges this popular view by examining the history of yoga, focusing on its emergence in modern India and its dramatically changing form and significance in the twentieth century. Joseph Alter argues that yoga's transformation into a popular activity idolized for its (...) health value is based on modern ideas about science and medicine. Alter centers his analysis on an interpretation of the seminal work of Swami Kuvalayananda, one of the chief architects of the Yoga Renaissance in the early twentieth century. From this point of orientation he explores current interpretations of yoga and considers how practitioners of yogic medicine and fitness combine the ideas of biology, physiology, and anatomy with those of metaphysics, transcendence, and magical power. The first serious ethnographic history of modern yoga in India, this fluently written book is must reading not only for students and scholars but also practitioners who seek a deeper understanding of how yoga developed over time into the exceedingly popular phenomenon it is today.

According to Russellian monism, consciousness is constituted at least partly by quiddities: intrinsic properties that categorically ground dispositional properties described by fundamental physics. If the theory is true, then consciousness and such dispositional properties are closely connected. But how closely? The contingency thesis says that the connection is contingent. For example, on this thesis the dispositional property associated with negative charge might have been categorically grounded by a quiddity that is distinct from the one that actually grounds it. Some argue (...) that Russellian monism entails the contingency thesis and that this makes its consciousness‐constituting quiddities epiphenomenal—a disastrous outcome for a theory that is motivated partly by its prospects for integrating consciousness into physical causation. We consider two versions of that argument, a generic version and an intriguing version developed by Robert J. Howell, which he bases on Jaegwon Kim's well‐known “exclusion argument.” We argue that neither succeeds. (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)

It is often claimed that Russellian monism carries a commitment to a structuralist conception of physics, on which physics describes the world only in terms of its spatiotemporal structure and dynamics. We argue that this claim is mistaken. On Russellian monism, there is more to consciousness, and to the rest of concrete reality, than spatiotemporal structure and dynamics. But the latter claim supports only a conditional claim about physics: _if_ structuralism about physics is true, then there is more to consciousness (...) and to the rest of concrete reality than physics describes. Given the fundamental nature of their position, Russellian monists can, we argue, deny the antecedent without inconsistency. We also draw out two significant consequences of that result. One is that it provides a response to some recent objections to Russellian monism, by Alyssa Ney and Eric Hiddleston. The other consequence concerns a line of reasoning known as _the structure and dynamics argument_—reasoning that is thought to motivate Russellian monism. In David J. Chalmers’s version, which is regarded as canonical, structuralism about physics is implied by a premise. If our main thesis is true, then that version is problematic, at least from the perspective of Russellian monists who take the argument to motivate their theory. However, we argue, the argument can be reformulated without relying on structuralism about physics. (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)

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)

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 (Journal of Consciousness Studies 2016, 2017) 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 (actual or possible) grounding roles. Not only is that assumption questionable: it is antithetical to Russellian monism. (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?

Physicalism is standardly construed as a form of monism, on which all concrete phenomena fall under one fundamental type. It is natural to think that monism, and therefore physicalism, is committed to a supervenience claim. Monism is true only if all phenomena supervene on a certain fundamental type of phenomena. Physicalism, as a form of monism, specifies that these fundamental phenomena are physical. But some argue that physicalism might be true even if the world is disorderly, i.e., not ordered by (...) supervenience relations in the way commonly supposed (Montero in J Philos 110:92–110, 2013; Leuenberger in Inquiry 57:151–174, 2014; Montero and Brown in Topoi 37(3):523–532, 2018; Zhong in Philos Stud 178(5):1529–1544, 2021). Unless these authors intend to challenge the claim that physicalism is a type of monism—a claim so central to the dialectic in philosophy of mind that rejecting it risks changing the subject—they are committed to challenging a supervenience requirement for monism. We argue that monism entails that there are substantial supervenience relations among concrete phenomena: relations that would not obtain in a disorderly world. Our argument thus has implications for debates about physicalism and supervenience, and sheds light on an under-discussed issue: what is implied by classifying a theory in the philosophy of mind as a form of monism? We also argue that physicalism’s commitment to monism creates problems for _via negativa_ physicalism, on which the physical is characterized negatively. (shrink)

An anthropological perspective on biosemiosis raises important questions about sociality, ecology and communication in contexts that encompass many different forms of life. As such, these questions are important for understanding the problem of religion in relation to social theory, as well as understanding our collective, biosocial animal history and the development of human culture, as an articulation of power, on an evolutionary time scale. The argument presented here is that biosemiotics provides a framework for extending Talal Asad’s genealogical critique of (...) religion to culture more broadly, providing an important perspective on power in relation to communication and in relation to the ‘supernatural’ attributes of language in a multi-species environment of signs and sign relationships.

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)

According to Jessica M. Wilson, physicalism is incompatible with the existence of fundamental mentality. Although widely endorsed, this No Fundamental Mentality constraint faces serious challenges, including alleged counterexamples. In this paper, I clarify the constraint, defend it against objections, and explain its basis.

According to Russellian monism, there are non-structural properties that both underlie physical, structural properties and help constitute, and thus necessitate, phenomenal properties (Alter and Pereboom Citation2023). Derk Pereboom (Citation2011, Citation2014, Citation2015, Citation2019) characterizes the relevant non-structural properties as absolutely intrinsic properties, where ‘P is an absolutely intrinsic property of X just in case P is an intrinsic property of X and P is not grounded in extrinsic properties of either X or parts of X’ (Pereboom Citation2019: 184). Justin Mendelow (Citation2024) (...) argues that Pereboom’s characterization is inadequate because it implies that non-structural properties do not necessitate phenomenal properties, either alone or in combination with structural properties. We argue that Mendelow’s argument rests on premises that Pereboom can reasonably reject. (shrink)

The supervenience requirement on physicalism says roughly that if physicalism is true then mental properties supervene on fundamental physical properties. After explaining the basis of the requirement, I defend it against objections presented by Lei Zhong (“Physicalism without supervenience,” Philosophical Studies 178 (5), 2021: 1529–44), Barbara Gail Montero (“Must physicalism imply supervenience of the mental on the physical?” Journal of Philosophy 110, 2013: 93–110), and Montero and Christopher Devlin Brown (“Making room for a this-worldly physicalism,” Topoi 37 (3), 2018: 523–32).

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.

In The Matter of Consciousness (TMOC), I defend Frank Jackson’s (1982, 1986, 1995) knowledge argument, which poses a significant challenge to physicalism. I also argue that the knowledge argument leads to Russellian monism.

In this issue of Cognition, Thompson and her colleagues challenge the results from a paper we published several years ago. That paper demonstrated that metacognitive difficulty or disfluency can trigger more analytical thinking as measured by accuracy on several reasoning tasks. In their experiments, Thompson et al. find evidence that people process information more deeply—but not necessarily more accurately—when they experience disfluency. These results are consistent with our original theorizing, but the authors misinterpret it as counter-evidence because they suggest that (...) accuracy is a measure of deeper processing rather than a contingent outcome of such processing. We further suggest that Thompson et al. err when they discriminate between “perceptual fluency” and “answer fluency,” the former of which is an element of the latter. Thompson et al. advance research by adding reaction time as a measure of deeper cognitive processing, but we caution against misinterpreting the meaning of accuracy. (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.

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.

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)

One of the chief difficulties we encounter as modern readers in perceiving the artistry of biblical narrative is precisely that we have lost most of the keys to the conventions out of which it was shaped. The professional Bible scholars have not offered much help in this regard, for their closest approximation to the study of convention is form criticism, which is set on finding recurrent regularities of pattern rather than the manifold variations upon a pattern that any system of (...) literary convention elicits; moreover, form criticism uses these patterns for excavative ends to support hypotheses about the social functions of the text, its historical evolution, and so forth.... The most crucial case in point is the perplexing fact that in biblical narrative more or less the same story often seems to be told two or three or more times about different characters, or sometimes even about the same character in different sets of circumstances. Three times a patriarch is driven by famine to a southern region where he pretends that his wife is his sister, narrowly avoids a violation of the conjugal bond by the local ruler, and is sent away with gifts. Twice Hagar flees into the wilderness from Sarah's hostility and discovers a miraculous well, and that story itself seems only a special variation of the recurrent story of bitter rivalry between a barren, favored wife and a fertile co-wife or concubine. That situation, in turn, suggests another oft-told tale in the Bible, of a woman long barren who is vouchsafed a divine promise of progeny, whether by God himself or through a divine messenger or oracle, and who then gives birth to a hero. Robert Alter, professor of Hebrew and comparative literature at the University of California at Berkeley, is the author of, among other works, Partial Magic: The Novel as a Self-Conscious Genre and Defenses of the Imagination. He has written a general literary study of biblical narrative, of which this essay forms a chapter. (shrink)

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.

Partant de la “ définition provisoire ” que N. Frye dans Le Grand Code donne du littéraire qui serait “ une structure verbale qui existe pour elle-même ”, Robert Alter pense que cette théorie, qui reste au centre de l'ouvrage, est vulnérable du point de vue de la théorie de la littérature et par rapport à la description de la nature de la Bible. Dans les deux parties de cet article, R. Alter entend montrer comment la conception imaginative de Frye (...) est fondée sur toute une série d'interprétations plus ou moins systématiquement erronées des textes bibliques. Il rappelle que malgré la présence de la métaphore dans sa poésie, la Bible laisse cette poésie dans un “ genre minoritaire ” par rapport à l'emploi de la prose, principal outil de narration typique du projet biblique.Starting with the “Provisory definition” that N.Frye, in The Great Code. The Bible and Literature,, gives to literary: "a verbal structure that exists for itself, Robert Alter thinks that this theory, which is basic to Frye's work, is vulnerable from the point of view of literary theory and in relation to the description of the nature of the Bible. In the two parts of this article, M Alter wants to show how the imaginative conception of Frye is founded on a series of interpretations of biblical texts more or less systematically wrong. He reminds us that despite the Presence of metaphor in its poetry, the Bible leaves this poetry in a "minority genre" in comparison with prose, the principal tool of narration typical of the biblical project.

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)

This essay traces the interlinked origins of two concepts found in Charles Darwin's writings: "unconscious selection," and sexual selection as applied to humanity's anatomical race distinctions. Unconscious selection constituted a significant elaboration of Darwin's artificial selection analogy. As originally conceived in his theoretical notebooks, that analogy had focused exclusively on what Darwin later would call "methodical selection," the calculated production of desired changes in domestic breeds. By contrast, unconscious selection produced its results unintentionally and at a much slower pace. Inspiration (...) for this concept likely came from Darwin's early reading of works on both animal breeding and physical ethnology. Texts in these fields described the slow and unplanned divergence of anatomical types, whether animal or human, under the guidance of contrasting ideals of physical perfection. These readings, it is argued, also led Darwin to his theory of sexual selection as applied to race, a theme he discussed mainly in his book The Descent of Man. There Darwin described how the racial version of sexual selection operated on the same principle as unconscious selection. He thereby effectively reunited these kindred concepts. (shrink)

How could physicalism be true of a world in which there are no fundamental physical phenomena? A familiar answer, due to Barbara Gail Montero and others, is that physicalism could be true of such a world if that world does not contain an infinite descent of mentality. Christopher Devlin Brown has produced a counterexample to that solution. We show how to modify the solution to accommodate Brown’s example: physicalism could be true of a world without fundamental physical phenomena if that (...) world does not contain an infinite descent of mentally constituted mentality. This solution is independently plausible and is available to physicalists of virtually all significant varieties. (shrink)

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)

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.

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

In Explanatory Optimism about the Hard Problem of Consciousness, Josh Weisberg tries to debunk the hard problem of consciousness. In his view, although consciousness appears to have DISC (directly accessed, indescribable, simple, contingently connected) properties, it does not: the appearance is better explained by automation, ‘a quick and seemingly spontaneous kind of cognitive processing, one whose underlying mechanistic activity is subjectively inaccessible to us’ (p. 92). I raise two problems for Weisberg’s argument. First, even if automation explains why consciousness appears (...) DISCy, that is not enough to explain the hard-problem intuitions. Second, neither methodological naturalism nor the impressive track record of scientific explanations suffices to justify ascribing presumptive status to the claim that consciousness can be fully explained in structural-dynamic terms.

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.

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.

This essay examines the analogy of a savage observing a sailing ship found in the final chapter of Darwin’s Origin of Species, an image that summed up his critique of British natural theology’s “design” thesis. Its inspiration drawn from works by Mandeville and Hume, and Darwin’s experience on the Beagle voyage, the ship illustration shows how Darwin conceived of natural selection’s relationship to theistic design in terms of a historical consciousness developed by Scottish Enlightenment thinkers. That outlook involved a dual (...) emphasis on the rationality of historical inquiry and the largely irrational character of the actual historical process. Symbolized by the history of ship construction, this perspective aided Darwin in formulating his response to British natural theology. (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.
