I develop a psychological account for how it is that we use imagination to metaphysically modalize, i.e., to reach conclusions about metaphysical modality. Specifically, I argue that Nichols and Stich’s (2003) cognitive theory of imagination can be extended to metaphysical modalizing. I then use the extension to explicate philosophical disagreements about whether a scenario is metaphysically possible. Thereafter, I address Nichols’ (2006) objection that psychologizing imagination makes it clear that imagination is unreliable when used to metaphysically modalize. The end result (...) is a naturalistic account for how imagination enables us to metaphysically modalize. (shrink)

Llamamos “conocimiento fenoménico” al conocimiento de nuestras experiencias conscientes: al saber cómo es tener una determinada experiencia. Los conceptos fenoménicos son aquellos asociados a este conocimiento y refieren, de modo introspectivo y directo, a las propiedades fenoménicas de nuestras experiencias. El papel que juegan estos conceptos es esencial en la filosofía de la mente contemporánea en la medida que muchos de sus defensores creen que una explicación adecuada de su naturaleza nos permitirá disipar un sinfín de rompecabezas epistemológicos (sobre la (...) relación de los individuos con sus estados fenoménicos) y metafísicos (que giran en torno a la naturaleza de la consciencia). Estos problemas son dos caras de la misma moneda y una respuesta a uno conlleva, necesariamente, implicaciones para el otro. Mi objetivo en este artículo es ofrecer una introducción al papel que desempeñan los conceptos fenoménicos en el debate metafísico en torno a la naturaleza de la consciencia. En especial, esta exposición se centra en la Estrategia de los Conceptos Fenoménicos, una de las respuestas fisicistas a los argumentos dualistas cuya conclusión es que no es posible acomodar una explicación de la consciencia en un marco fisicista. Para ello, en §1 describo la tesis central del fisicismo y presento uno de los más célebres argumentos en su contra: el argumento del conocimiento. Enseguida, en §2 expongo qué son los conceptos fenoménicos y en qué difieren de otro tipo de conceptos, en §3 explico el modus operandi de la Estrategia de los Conceptos Fenoménicos en respuesta a los retos dualistas señalados en §1, y en §4 menciono algunas de las objeciones más frecuentes en contra de esta estrategia. Finalmente, en §5 hago una síntesis de los puntos esenciales discutidos en este artículo. (shrink)

Monism is our name for a range of views according to which the connection between dispositions and their categorical bases is intimate and necessary, or on which there are no categorical bases at all. In contrast, Dualist views hold that the connection between dispositions and their categorical bases is distant and contingent. This paper is a defence of Monism against an influential conceivability argument in favour of Dualism. The argument suggests that the apparent possibility of causal behaviour coming apart from (...) categorical bases is best explained by Dualism. We argue that Monism can explain the apparent possibility as well, if we take metaphysically alien laws — namely, laws whose metaphysical nature is alien to the actual world — into account. (shrink)

This paper argues for a view of free will that I will call the conceptual impossibility of the truth of free will error theory - the conceptual impossibility thesis. I will argue that given the concept of free will we in fact deploy, it is impossible for our free will judgements - judgements regarding whether some action is free or not - to be systematically false. Since we do judge many of our actions to be free, it follows from the (...) conceptual impossibility thesis that many of our actions are in fact free. Hence it follows that free will error theory - the view that no judgement of the form ‘action A was performed freely’ - is false. I will show taking seriously the conceptual impossibility thesis helps makes good sense of some seemingly inconsistent results in recent experimental philosophy work on determinism and our concept of free will. Further, I will present some reasons why we should expect to find similar results for every other factor we might have thought was important for free will. (shrink)

According to the preference-centric approach to understanding partial belief, the connection between partial beliefs and preferences is key to understanding what partial beliefs are and how they’re measured. As Ramsey put it, the ‘degree of a belief is a causal property of it, which we can express vaguely as the extent to which we are prepared to act on it’ The Foundations of Mathematics and Other Logical Essays, Routledge, Oxon, pp 156–198, 1931). But this idea is not as popular as (...) it once was. Nowadays, the preference-centric approach is frequently dismissed out-of-hand as behaviouristic, unpalatably anti-realist, and/or prone to devastating counterexamples. Cases like Eriksson and Hájek’s :183–213, 2007) preferenceless Zen monk and Christensen’s :356–376, 2001) other roles argument have suggested to many that any account of partial belief that ties them too closely to preferences is irretrievably flawed. In this paper I provide a defence of preference-centric accounts of partial belief. (shrink)

In this thesis, I will defend a new kind of compatibilist account of free action, indirect conscious control compatibilism (or indirect compatibilism for short), and argue that some of our actions are free according to it. My argument has three components, and involves the development of a brand new tool for experimental philosophy, and the use of cognitive neuroscience. The first component of the argument shows that compatibilism (of some kind) is a conceptual truth. Contrary to the current orthodoxy in (...) the free will literature, which is that our concept of free will is an incompatibilist concept - a concept according to which we have free will only if determinism is false - I will show that our concept of free will is in fact a compatibilist concept - a concept according to which we can have free will even if determinism is true - and I do so using a new experimental philosophy methodology inspired by two-dimensional semantics. -/- Of course, even if our concept of free will is a compatibilist concept, this does not mean that there are any free actions in the world: the current empirical evidence from the brain sciences appears to show that there might be no, or very few, free actions in the world, even on many compatibilist understandings of what it would take for there to be free will. The second component of the argument addresses this concern by extending our understanding of compatibilism. Agents act freely either when their actions are caused by compatibilistically acceptable psychological processes, or are indirectly caused by those same processes. Hence the name of my account: indirect compatibilism. -/- The final component of the argument defends my new account against some interesting objections and provides evidence from cognitive neuroscience that some of our actions count as free by the lights of indirect compatibilism.

According to the scrutability argument against physicalism, an a priori gap between the physical and conscious experience entails a lack of necessitation and the falsity of physicalism. This paper investigates the crucial premise of the scrutability argument: the inference from an a priori gap to a lack of necessitation. This premise gets its support from modal rationalism, according to which there are important, potentially constitutive, connections between a priori justification and metaphysical modality. I argue against the strong form of modal (...) rationalism that underwrites the scrutability argument and suggest a more moderate rationalist view. I offer a novel demonstrative reply to the scrutability argument, according to which demonstratives play a vital role in the generation of meaning for our representations of conscious experience. This connection between conscious experience and demonstratives, rather than a metaphysical gap generated by the truth of dualism, is the source of the epistemic gap between consciousness and the physical.

This is the introductory essay to the collection of essays: 'Acquaintance: New Essays' (eds. Knowles & Raleigh, forthcoming, OUP). In this essay I provide some historical background to the concept of acquaintance. I examine various Russellian theses about acquaintance that contemporary acquaintance theorists may wish to reject. I consider a number of questions that acquaintance theorists face. I provide a survey of current debates in philosophy where acquaintance has recently been invoked. And I also provide brief summaries of the other (...) essays in this volume. (shrink)

This paper explores early Australasian philosophy in some detail. Two approaches have dominated Western philosophy in Australia: idealism and materialism. Idealism was prevalent between the 1880s and the 1930s, but dissipated thereafter. Idealism in Australia often reflected Kantian themes, but it also reflected the revival of interest in Hegel through the work of ‘absolute idealists’ such as T. H. Green, F. H. Bradley, and Henry Jones. A number of the early New Zealand philosophers were also educated in the idealist tradition (...) and were influential in their communities, but produced relatively little. In Australia, materialism gained prominence through the work of John Anderson, who arrived in Australia in 1927, and continues to be influential. John Anderson had been a student of Henry Jones, who might therefore be said to have influenced both main strands of Australian philosophical thought. (shrink)

Eddy Nahmias, with various collaborators, has used experimental data to argue for the claim that folk intuition is generally compatibilist. We try to undermine this claim in two ways. First, we argue that the various formulations of determinism he uses are not conceptually equivalent, jeopardizing the kinds of conclusions that can be drawn from the resulting data. Second, prompted by these conceptual worries we supplement the typical quantitative surveys that dominate the extant literature with short qualitative interviews. This, in turn, (...) guides us to make a minor modification to the quantitative survey that provides better access to the relevant folk intuitions. (shrink)

Philosophy and Literature is an internationally renowned refereed journal founded by Denis Dutton at the University of Canterbury, Christchurch. It is now published by the Johns Hopkins University Press. Since its inception in 1976, Philosophy and Literature has been concerned with the relation between literary and philosophical studies, publishing articles on the philosophical interpretation of literature as well as the literary treatment of philosophy. Philosophy and Literature has sometimes been regarded as iconoclastic, in the sense that it repudiates academic pretensions, (...) insidious jargon and institutional vogue. Dutton, who remains the editor, still writes a regular column. A distinctive feature of Philosophy and Literature was the annual Bad Writing Contest, held from 1995–98, which sought to identify (and publish) the ‘most stylistically lamentable passages’ of academic prose, often to great amusement.

This dissertation contains four independent essays addressing a cluster of related topics in the philosophy of mind. Chapter 1: “Fundamentality Physicalism” argues that physicalism can usefully be conceived of as a thesis about fundamentality. The chapter explores a variety of other potential formulations of physicalism (particularly modal formulations), contrasts fundamentality physicalism with these theses, and offers reasons to prefer fundamentality physicalism over these rivals. Chapter 2:“Modal Rationalism and the Demonstrative Reply to the Master Argument Against Physicalism” introduces the Master Argument (...) Against Physicalism and investigates its crucial premise: the inference from an a priori gap between the physical and consciousness to a lack of necessitation between the two. I argue against the strong form of modal rationalism that underwrites the master argument and offer a more moderate rationalist view. I offer a novel demonstrative reply to the master argument, according to which a connection between conscious experience and demonstratives, not dualism, is the source of the epistemic gap between consciousness and the physical. Chapter 3: “Conceptual Mastery and the Knowledge Argument” argues that Frank Jackson’s famous anti-physicalist knowledge argument featuring Mary, a brilliant neuroscientist raised in a black and white room, founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been removed, Mary can know the relevant truths. Chapter 4: “Toward a Theory of Conceptual Mastery” investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I argue against three views of conceptual mastery, according to which conceptual mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain intuitions. I propose and respond to objections to my own “meaning postulate view” of the conditions under which a thinker has mastery of a concept. (shrink)

Many have argued that there is something that is a priori about all necessary truths, including a posteriori necessities. According to a particularly popular claim of this kind, one can know a priori whether a sentence is G-necessary, i.e. whether it is either necessarily true or necessarily false. In this paper, I identify the most plausible version of this claim and I argue that it fails. My discussion also reveals, and depends upon, an important feature of putative natural kind terms (...) that has been widely overlooked. I conclude by outlining a proposal of what is really a priori about necessities. (shrink)

I assume that there exists a general phenomenon, the phenomenon of the explanatory gap, surrounding consciousness, normativity, intentionality, and more. Explanatory gaps are often thought to foreclose reductive possibilities wherever they appear. In response, reductivists who grant the existence of these gaps have offered countless local solutions. But typically such reductivist responses have had a serious shortcoming: because they appeal to essentially domain-specific features, they cannot be fully generalized, and in this sense these responses have been not just local but (...) parochial. Here I do better. Taking for granted that the explanatory gap is a genuine phenomenon, I offer a fully general diagnosis that unifies these previously fragmented reductivist responses. (shrink)

This paper develops an endurantist theory of persistence. The theory is built around one basic tenet, which concerns existence at a time – the relation between an object and the times at which that object is present. According to this tenet, which I call transcendentism, for an object to exist at a time is for it to participate in events that are located at that time. I argue that transcendentism is a semantically grounded and metaphysically fruitful. It is semantically grounded, (...) insofar as a semantic analysis of our temporal talk favors it over rivals. It is metaphysically fruitful, insofar as the theory of persistence that can be built around it – the transcendentist theory of persistence, to give it a name – requires neither temporal parts nor the problematic commitments to which all extant forms of endurantism are committed, such as the possibility of extended simples or multilocation.

This paper is about philosophical disputes where the literal content of what speakers communicate concerns such object-level issues as ground, supervenience, or real definition. It is tempting to think that such disputes straightforwardly express disagreements about these topics. In contrast to this, I suggest that, in many such cases, the disagreement that is expressed is actually one about which concepts should be employed. I make this case as follows. First, I look at non-philosophical, everyday disputes where a speaker employs a (...) metalinguistic usage of a term. This is where a speaker uses a term to express a view about the meaning of that term, or, relatedly, how to correctly use that term. A metalinguistic negotiation is a metalinguistic dispute that concerns a normative issue about what a word should mean, or, similarly, about how it should be used, rather than the descriptive issue about what it does mean. I argue that the same.. (shrink)

The Phenomenal Concept Strategy offers the physicalist perhaps the most promising means of explaining why the connection between mental facts and physical facts appears to be contingent even though it is not. In this article, we show that the large body of evidence suggesting that our concepts are often embodied and grounded in sensorimotor systems speaks against standard forms of the PCS. We argue, nevertheless, that it is possible to formulate a novel version of the PCS that is thoroughly in (...) keeping with embodied cognition, focuses on features of physical concepts, and succeeds in explaining the appearance of contingency.

In Constructing the World, Chalmers seeks to articulate and defend an important epistemic accessibility thesis, the Scrutability of Truth, which is crucial to Chalmers’ rationalist approach to meaning and modality. Chapters 3 and 4 of the book are devoted to persuading us that the move from weaker to stronger forms of Scrutability is intuitively plausible. In these comments, I want to question this move. The plausibility of strong forms of Scrutability hinges on controversial views about epistemic norms for answering ‘what (...) is x?’ questions that semantic externalists have good reason to reject.

If Australasian philosophers constitute the kind of group to which a collective identity or broadly shared self-image can plausibly be ascribed, the celebrated history of Australian materialism rightly lies close to its heart. Jack Smart’s chapter in this volume, along with an outstanding series of briefer essays in A Companion to Philosophy in Australia and New Zealand (Forrest 2010; Gold 2010; Koksvik 2010; Lycan 2010; Matthews 2010; Nagasawa 2010; Opie 2010; Stoljar 2010a), effectively describe the naturalistic realism of Australian philosophy (...) of mind. In occasional semi-serious psychogeographic speculation, this long-standing and strongly-felt intellectual attitude has been traced back to the influences of our light, land, or lifestyle (Devitt 1996, x; compare comments by Chalmers and O’Brien in Mitchell, 2006). Australasian work in philosophy of mind and cognition has become more diverse in the last 40 years, but is almost all still marked, in one way or another, by the history of these debates on materialism.

It's a common idea in philosophy that we possess a peculiar kind of "phenomenal concept" by which we can think about our conscious states in "inner" and "direct" ways, as for example, when I attend to the way a current pain feels and think about this feeling as such. Such phenomenal ways of thinking figure in a variety of theoretical contexts. The bulk of this article discusses their use in a certain strategy – the phenomenal concept strategy – for defending (...) the physicalist view that conscious states are reducible to brain states. It also considers, more briefly, how phenomenal concepts have been used to defend dualism about consciousness, and how they have been used to explain our special access to our consciousness. It concludes with a discussion about whether, and in what more precise sense of the term, we at all possess "phenomenal concepts" of our conscious states. (shrink)

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

Dualists say plausible things about our mental concepts: there is a way of thinking of pain, in terms of how it feels, which is independent of causal role. Physicalists make attractive ontological claims: the world is wholly physical. The attraction of a posteriori physicalism is that it has seemed to do both: to agree with the dualist about our mental concepts, whilst retaining a physicalist ontology. In this paper I argue that, in fact, a posteriori physicalism departs from the dualist's (...) intuitive picture of our phenomenal concepts in just as radical a manner as more traditional forms of physicalism. Whereas the physicalism of David Lewis and David Armstrong is counterintuitive in holding that our only way of thinking about pain is in terms of its causal role, the physicalism of David Papineau and Brian Loar departs from common sense in holding that our phenomenal concept of pain is opaque: thinking of pain in terms of how it feels reveals nothing of what it is for something to feel pain. The arguments of David Chalmers and Frank Jackson against a posteriori physicalism involve general claims about all concepts. In contrast, my argument makes a claim only about phenomenal concepts: phenomenal concepts are not opaque. (shrink)

I argue that an identity theorist can successfully resist a Kripkean modal argument by employing what I call a metaconceptual move. Furthermore, by showing how this move fails to apply straightforwardly to Chalmers' argument, I clarify the nature of the threat presented by Chalmers and how it differs from a Kripkean modal argument.

This chapter sketches what is considered the best interpretation of physicalism, rehearses the best way of defending it, and shows that the physicalism forthcoming is still going to be less than fully satisfying; it is going to leave us short of the satisfaction that might be expected from a philosophical theory. The chapter is organized into three sections. The first section gives an interpretation of physicalism in the spirit of Frank Jackson's; this involves a rich version under which the way (...) things are phenomenally is derivable in principle from physical premisses. The second sketches a representationalist or intentionalist argument for physicalism about phenomenal experience, one which also appeals to Jackson. The third section argues that even if we accept this case for a rich physicalism, still we should not expect to find the doctrine fully satisfying; the simulatory gap will stand between us and a sort of satisfaction that we might have expected to achieve.

The recent literature on mental causation has not been kind to nonreductive, materialist functionalism (‘functionalism’, hereafter, except where that term is otherwise qualified). The exclusion problem2 has done much of the damage, but the epiphenomenalist threat has taken other forms. Functionalism also faces what I will call the ‘problem of metaphysically necessary effects’ (Block, 1990, pp. 157-60, Antony and Levine, 1997, pp. 91-92, Pereboom, 2002, p. 515, Millikan, 1999, p. 47, Jackson, 1998, pp. 660-61). Functionalist mental properties are individuated partly (...) by their relation to the very effects those properties’ instantiations are thought to cause. Consequently, functionalist causal generalizations would seem to have the following problematical structure: The state of being, among other things, a cause of e (under such-andsuch conditions) causes e (under those conditions).3 The connection asserted lacks the contingency one would expect of a causal generalization. Mental states of the kind in question are, by metaphysical necessity, causes of e; any state that does not cause e is thereby a different kind of state. Yet, a mental state’s being the sort of state it is must play some causal role if functionalism is to account for mental causation.4 In what follows, I first articulate more fully the problem of metaphysically necessary effects. I then criticize three functionalist attempts to solve the problem directly. Given the failure of functionalist efforts to meet the problem head-on, I consider less direct strategies: these involve formulating functionalism or its causal claims in such a way that they appear not to generate the problem of metaphysically necessary effects. I argue against these indirect solutions, in each case concluding either that the problem still arises or that avoiding it requires the adoption of an unorthodox form of functionalism (itself a surprising result). In the final.. (shrink)

What has come to be known as “a priori physicalism” is the thesis, roughly, that the non-physical truths in the actual world can be deduced a priori from a complete physical description of the actual world. To many contemporary philosophers, a priori physicalism seems extremely implausible. In this paper I distinguish two kinds of a priori physicalism. One sort – strict a priori physicalism – I reject as both unmotivated and implausible. The other sort – liberal a priori physicalism – (...) I argue is both motivated and plausible. This variety of a priori physicalism insists that the necessitation of non-physical truths by the physical facts must be underwritten in a certain fashion by a priori knowledge, but the a priori knowledge need not amount to a simple deduction of the non-physical truths from a complete physical description of the world. Further, this sort of liberal a priori physicalism has the advantage that it offers hope for a genuinely satisfying account of how the physical facts manage to necessitate the facts about phenomenal consciousness – thereby in effect solving the “hard problem” of consciousness. The first half of the paper sets out the motivation for liberal a priori physicalism and its superiority to the strict version; the second half presents one strategy available to the liberal a priori physicalist for showing how consciousness can be accommodated in a purely physical world.

This paper aims to determine whether we can locate temporal passage in a non-dynamical (block universe) world. In particular, we seek to determine both whether temporal passage can be located somewhere in our world if it is non-dynamical, and also to home in on where in such a world temporal passage can be located, if it can be located anywhere. We investigate this question by seeking to determine, across three experiments, whether the folk concept of temporal passage can be satisfied (...) in our world if it is non-dynamical, and, if it can, what sort of thing in our world satisfies that concept. In particular, we focus on the question of whether that concept (if satisfied) is satisfied by something mind-dependent or something mind-independent. In other words, we ask, is temporal passage something that is at least partially in the mind, or is it entirely external to the mind? We find, contrary to what is often assumed by dynamists and non-dynamists alike, that the folk concept of temporal passage is satisfied in our world conditional on it being non-dynamical, and that the concept is satisfied by something mind-independent. This provides further ammunition for recent deflationary accounts of temporal passage that attempt to locate passage somewhere in our non-dynamical world. (shrink)

In this paper, we clarify, unpack, and ultimately resist what is perhaps the most prominent argument for the compatibility of free will and determinism: the epistemic argument for compatibilism. We focus on one such argument as articulated by David Lewis: (i) we know we are free, (ii) for all we know everything is predetermined, (iii) if we know we are free but for all we know everything is predetermined, then for all we know we are free but everything is predetermined, (...) (iv) if for all we know we are free but predetermined, then it is really possible that we are, so (v) compatibilism. We uncover how the crucial epistemic modality underlying (iv) must be understood, and contend that, understood this way, the libertarian can resist (iv). Importantly, however, resisting the argument does commit the libertarian to what has been called “flip-flopping”—but we argue that this is perfectly coherent. We conclude by articulating two crucially ways the libertarian can resist the argument, by saying that we can know that determinism is false "from the armchair". (shrink)

Philosophers often hold that the aim of conceptual analysis is to discover the representational content of a given concept such as freewill, belief, or law. In From Metaphysics to Ethics and other recent work, Frank Jackson has developed a theory of conceptual analysis that is one of the most advanced systematizations of this widespread idea. I argue that this influential way of characterizing conceptual analysis is too narrow. I argue that it is possible that an expressivist account could turn out (...) to be correct as a genuine conceptual analysis of a genuine concept. I claim that since an expressivist analysis does not aim to discover the representational content of a given concept—and, indeed, might itself be based on the idea that the concept in question is not even representational in nature—the possibility of expressivist conceptual analysis shows that Jackson’s theory of conceptual analysis is incomplete as it currently stands. I conclude that Jackson needs to either shift his basic understanding of the nature of conceptual analysis or commit to a particular normative reinterpretation of his project. (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)

David Chalmers' conceivability argument against physicalism relies on the entailment from a priori conceivability to metaphysical possibility. The a posteriori physicalist rejects this premise, but is consequently committed to psychophysical strong necessities. These don't fit into the Kripkean model of the necessary a posteriori, and they are therefore, according to Chalmers, problematic. But given semantic assumptions that are essential to the conceivability argument, there is reason to believe in microphysical strong necessities. This means that some of Chalmers' criticism is unwarranted, (...) and the rest equally afflicts the dualist. Moreover, given that these assumptions are independently plausible, there's a general case to be made for the existence of strong necessities outside the psychophysical domain. (shrink)

Illusionists and a posteriori physicalists agree entirely on the metaphysical nature of reality — that all concrete entities are composed of fundamental physical entities. Despite this basic agreement on metaphysics, illusionists hold that phenomenal consciousness does not exist, whereas a posteriori physicalists hold that it does. One explanation for this disagreement would be that either the illusionists have too demanding a view about what consciousness requires, or the a posteriori physicalists have too tolerant a view. However, we will argue that (...) this divergence of opinion is merely an upshot of the semantic indeterminacy of the term 'conscious' and its cognates. We shall back up this diagnosis by showing how semantic indeterminacy of the kind in question is a pervasive feature of language. By illustrating this pattern with a range of historical examples, we shall show how the dispute between the illusionists and a posteriori physicalists is one instance of a common kind of terminological imprecision. The disagreement between them is thus not substantial. In effect, the two sides differ only about how to make an indeterminate term precise. The moral is that they should stop looking for arguments designed to settle the dispute in their favour. (shrink)

that there is something rationally or conceptually defective in judging that an act is right without being in any way motivated towards it—is one which has tended to lead either to error theories of ethics on the one hand, or acceptance of the truth of internalism on the other. This paper argues that it does play a kind of subject-setting role, but that our responses to cases can be rationalised without requiring that internalism is true for ethical realism to be (...) vindicated. Instead what is required is that something like internalism be believed to be true. The widespreadness of the internalist intuition is part of what makes it the case that some actions are right and others wrong. Of course these beliefs might be false—as the present author holds—consistent with ethical realism, just so long as they are widely held, and whatever else it takes to vindicate realism is the case. In such a situation, widespread false belief would be part of what makes it so that some acts are right, and others wrong. (shrink)

A recent strategy for defending physicalism about the mind against the zombie argument relies on the so-called conditional analysis of phenomenal concepts. According to this analysis, what kinds of states our phenomenal concepts refer to depends crucially on whether the actual world is merely physical or not. John Hawthorne, David Braddon-Mitchell and Robert Stalnaker have claimed, independently, that this analysis explains the conceivability of zombies in a way consistent with physicalism, thus blocking the zombie argument. Torin Alter has recently presented (...) three arguments against the conditional analysis strategy. This paper defends the conditional analysis strategy against Alter’s objections. (shrink)

Much of contemporary philosophy of mind is dominated by the intersection of three topics: physicalism, the conceivability argument, and the necessary a posteriori. I will be concerned here to describe the consensus view of these topics; to explain why I think this account is mistaken; and to briefly sketch an alternative.

Jackson argues that conceptual analysis plays a modest, albeit crucial, role in ‘serious metaphysics’: roughly, the project of demystifying phenomena we take to be mysterious by locating them in the natural world. This defence of conceptual analysis is associated with ‘the Canberra Plan’, a philosophical methodology that has its roots in the works of both Lewis :427–446, 1970, Australas J Philos 50:249–258, 1972) and Jackson. There is, however, a distinction to be drawn between conceptual analysis, as it is typically employed (...) in the Canberra plan, and a version of it defended by Jackson himself. In this paper, I elucidate this distinction, and employ examples from the history of science to argue the use of the former, but not the latter, incurs certain problems of conceptual change. Moreover, I also argue neither can be used to undertake serious metaphysics—the former because of the aforementioned problems, and the latter due to the machinery it employs to solve them. (shrink)

In its recent history, the philosophy of mind has come to resemble an entry into the genre of Hammer horror or pulpy science fiction. These days it is unusual to encounter a major philosophical work on the mind that is not populated with bats, homunculi, swamp-creatures, cruelly imprisoned genius scientists, aliens, cyborgs, other-worldly twins, self-aware Computer programs, Frankenstein-monster-like ‘Blockheads,’ or zombies. The purpose of this paper is to review the role in the philosophy of mind of one of these fantastic (...) thought-experiments — the zombie — and to reassess the implications of zombie arguments, which I will suggest have been widely misinterpreted. I shall argue that zombies, far from being the enemy of materialism, are its friend; and furthermore that zombies militate against the computational model of consciousness and in favour of more biologically-rooted conceptions, and hence that zombie- considerations support a morereductivekind of physicalism about consciousness than has been in vogue in recent years.

Thought experiments have played a central role in philosophical methodology, largely as a means of elucidating the nature of our concepts and the implications of our theories.1 Particular attention is given to widely shared “folk” intuitions – the basic untutored intuitions that the layperson has about philosophical questions.2 The folk intuition is meant to underlie our core metaphysical concepts, and philosophical analysis is meant to explicate or sometimes refine these naïve concepts. Consistency with the deliverances of folk intuitions is a (...) sign that the philosopher is making contact with his object of interest. In order to explore folk concepts, people are often asked to provide their intuitions about a state of affairs in some alternate universe or possible world, one that differs in particular, precise ways from the way things are in the actual world. Here we provide evidence that people’s intuitions about moral responsibility sometimes diverge across worlds even when the facts about these worlds are the same. Which world one considers actual affects at least some philosophical judgments, suggesting that it is not just possible worlds to which our intuitions are tied. We will present several possible explanations for the asymmetry we have identified, and we’ll consider some implications for philosophical intuition. (shrink)

The conditional analysis of phenomenal concepts purports to give physicalists a way of understanding phenomenal concepts that will allow them to (1) accept the zombie intuition, (2) accept that conceivability is generally a good guide to possibility, and yet (3) reject the conclusion that zombies are metaphysically possible. It does this by positing that whether phenomenal concepts refer to physical or nonphysical states depends on what the actual world is like. In this paper, I offer support for the Chalmers/Alter objection (...) that the conditional analysis fails to accommodate the true zombie intuition, and develop a new and far more powerful argument against the conditional analysis. I argue that, as stated, the conditional analysis is radically incomplete. But when fully fleshed out, the analysis becomes viciously circular. The only way to avoid this circularity is to adopt a species of analytic functionalism, on which it’s a priori that phenomenal concepts refer to the state (perhaps physical, perhaps nonphysical) that actually plays so-and-so functional role. While this rigidified analytic functionalism is coherent, it is highly unattractive, running contrary to both the intuitions that motivate functionalism and the intuitions that motivated the conditional analysis.

Suppose P is the conjunction of all truths statable in the austere vocabulary of an ideal physics. Then phsicalists are likely to accept that any truths not included in P are different ways of talking about the reality specified by P. This ‘redescription thesis’ can be made clearer by means of the ‘strict implication thesis’, according to which inconsistency or incoherence are involved in denying the implication from P to interesting truths not included in it, such as truths about phenomenal (...) consciousness. Commitment to the strict implication thesis cannot be escaped by appeal to a posteriori necessary identities or entailments. A minimal physicalism formulated in terms of strict implication is preferable to one based on a priori entailment. (shrink)

According to a widely held physicalist view, consciousness is identical with some physical or functional phenomenon just as liquidity is identical with loose molecular connection. To many of us, this claim about consciousness seems more problematic than the claim about liquidity. To many—including many physicalists—the identification of consciousness with some physical phenomenon even seems “absurd” or “crazy”. A full defence of physicalism should explain why the allegedly correct hypothesis comes across this way. If physicalism is true and we have reason (...) to accept it, why does it seem “absurd”? One possibility is that this is fully explained by the fact that we have an erroneous understanding of consciousness or its physical basis. This explanation is embraced by few if any physicalists. It is rejected by many, including proponents of the “phenomenal concept strategy”, which lately has become the dominant strategy for defending physicalism. But the “error explanation” is clearly the most plausible explanation that is available to physicalists. So this paper argues. (shrink)

We tend to think that our concepts are stable in the sense that, whilst their extensions may vary across distinct epistemic scenarios, the reference-fixing conditions by which we discover these extensions remain fixed. This paper challenges this orthodoxy. In particular, it aims to motivate the position that some concepts are unstable in that their reference-fixing conditions themselves vary across distinct epistemic scenarios. Furthermore, it aims to draw out the implications such instability has for epistemic possibility and apriority. I shall argue (...) that when unstable concepts are concerned epistemic space will be widened, which in turn will restrict our a priori knowledge; and in ways that might be salient to solving certain familiar philosophical problems.

There is a good deal of disagreement about composition. There is firstorder disagreement: there are radically different answers to the special composition question—the question of under what circumstances the xs compose a y. There is second-order disagreement: there are different answers to the question of whether first-order disagreement is real or merely semantic. Virtually all disputants with respect to both the first-and second-order issues agree that the answer or answers to the special composition question will take the form of a (...) necessary truth or truths even though, as I will argue, such answers do not appear to be good candidates to be necessary truths. This paper provides an analysis of the concept of as it pertains to concrete objects, that fulfils two functions. First, it explicates the sense in which claims about composition are contingent and the sense in which they are necessary, and second, it provides a way of understanding when first-order disputes are substantial and when they are merely semantic.
