While concerns of the mental being causally excluded by the physical have persistently plagued non-reductive physicalism, such concerns are standardly taken to pose no problem for reductive type physicalism. Type physicalists have the obvious advantage of being able to countenance the reduction of mental properties to their physical base properties by way of type identity, thereby avoiding any causal competition between instances of mental properties and their physical bases. Here, I challenge this widely accepted advantage (...) of type physicalism over non-reductive physicalism in avoiding the causal exclusion of the mental. In particular, I focus on Jaegwon Kim’s influential version of the causal exclusion argument, namely, his supervenience argument. I argue that type physicalism’s advantage is undermined by the following two things: (1) the generalizability of the supervenience argument, and (2) type physicalism’s incompatibility with mental properties at the fundamental level. This involves evaluating the generalization objection to the supervenience argument, probing the metaphysics of physicalism, and showing how (1) and (2) combine in a way that appears underappreciated given the general confidence in type physicalism’s advantage.

It is part of Jaegwon. Kim’s life’s work that he has demonstrated that non-reductive physicalism is not an option in the philosophy of the mental. However, he also recognizes the problems of mentalism that cannot be solved by physicalism. This concerns above all phenomenal consciousness, which resists naturalization. In the philosophy of the mental, this addresses a very fundamental problem of what the place of the mental is in the physical world. It is Kim’s merit in the philosophy (...) of the mental to have shown non-reductive physicalism to be contradictory and qualitative experience to have shown its place as a phenomenon that cannot be explained physically. But Kim wants to be a physicalist and functionalist at the same time. For this he describes his position as “physicalism, or something near enough”. It is to Kim’s credit that he has presented non-reductive physicalism as a variation of British emergentism. But this raises a very fundamental problem, whether this is a valid research program of systematization of mental experience or whether it needs another research program. (shrink)

This paper advances a version of physicalism which reconciles the “a priori entailment thesis” (APET) with the analytic independence of our phenomenal and physical vocabularies. The APET is the claim that, if physicalism is true, the complete truths of physics imply every other truth a priori. If so, “cosmic hermeneutics” is possible: a demon having only complete knowledge of physics could deduce every truth about the world. Analytic independence is a popular physicalist explanation for the apparent “epistemic gaps” (...) between phenomenal and physical truths. The two are generally seen as incompatible, since the demon’s deductions seem to presuppose analytic connections between physical and phenomenal terms. I begin by arguing, in support of the APET, that implications from the complete truths of physics to phenomenal truths cannot be a posteriori. Such implications are (according to the physicalist) necessarily true. But they cannot be Kripke-style a posteriori necessities, since (according to the physicalist) the complete truths of physics fix any relevant a posteriori facts about the reference of terms. I then show how the physicalist can turn the tables: the demon can exploit the physical fixing of reference to bridge the gap between the vocabularies, by deducing when phenomenal and physical terms co-refer. This opens the way for a “type-C” physicalism, which accepts in-principle deducibility while still appealing to analytic independence to explain why we (who are not demons) find it impossible to see phenomenal-physical connections a priori.

The majority of physicalists are type-B physicalists – believing that the phenomenal-physical truths are only knowable a posteriori. This paper aims to show why this view is misguided. The strategy is to design an agent who (1) has full general physical knowledge, (2) has phenomenal concepts, and yet (3) is wired such that she would be in a position to immediately work out the phenomenal-physical truths. I argue that this derivation yields a priori knowledge. The possibility of such a (...) creature entails that – contrary to type-B physicalism – there is not an ideal epistemic gap between the phenomenal and the physical truths. Out of this argument against type-B physicalism emerges a positive result: a new and compelling version of type-A physicalism, roughly a type-A phenomenal concept strategy. (shrink)

In this paper I shall carefully examine some recent arguments for dualism. These arguments presuppose a strong version of physicalism that I consider inappropriate. I shall try to show that, if we reformulate the thesis of physicalism according to Kim's view of physicalism (in terms of the supervenience relation), there is a third option, a version of type physicalism, where physicalism and quaiia could be conciliated. In order to sketch this option, I shall consider (...) the main argument against type physicalism: the explanatory gap argument, and two arguments that Kim mentions against physicalism: the inverted spectrum / zombies argument and the intrinsicality argument. I shall try to show that these three arguments depend upon a misconception of the nature of our ordinary mental concepts. (shrink)

Supervenience physicalism holds that all facts, of whatever type, globally supervene upon the physical facts, even though neither type-type nor token-token nonphysical-physical identities hold. I argue that, invoked like this, supervenience is metaphysically mysterious, needing explanation. I reject two explanations (Lewis and Forrest). I argue that the best explanation of the appearance of supervenience is an error-theoretic, projectivist one: there are no nonphysical properties, but we erroneously project such onto the physical world in a systematic way, (...) yielding the appearance of supervenience.

Flat Physicalism is a theory of through and through type reductive physicalism, understood in light of recent results in the conceptual foundations of physics. In Flat Physicalism, as in physics, so-called "high level" concepts and laws are nothing but partial descriptions of the complete states of affairs of the universe. "Flat physicalism" generalizes this idea, to form a reductive picture in which there is no room for levels, neither explanatory nor ontological. The paper explains how (...) phenomena that seem to be cases of multiple realization of special sciences kinds by physical kinds are fully explains in a reductive physicalist way. Finally, the paper exemplifies the fruitfulness of this reductive approach by showing how it can account even for a case of high-level anomaly in a deterministic universe (for example anomaly of the mental, should this turn our to be a fact about the world) - a result that may be called Anomalous Physicalism.

ABSTRACTType B, or a posteriori, physicalism is the view that phenomenal-physical identity statements can be necessarily true, even though they cannot be known a priori—and that the key to understanding their status is to understand the special features of our phenomenal concepts, those concepts of our experiential states acquired through introspection. This view was once regarded as a promising response to anti-physicalist arguments that maintain that an epistemic gap between phenomenal and physical concepts entails that phenomenal and physical properties (...) are distinct. More recently, however, many physicalists have lost confidence in the view, and have proposed less promising defences of physicalism—or have become outright sceptical about its prospects. I argue here that these physicalists have underestimated the resources of Type B physicalism and are thereby retreating too quickly—or fighting battles that have already been won. (shrink)

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)

In this paper, I provide further elaboration of my theory of conscious experience, in response to the criticisms made by David Cole, and I directly address a number of the issues he raises. In particular, I examine Cole's claim that functionalism rather than neurophysiology is the theoretical key to consciousness. I argue that weak type-physicalism provides an analysis which is more fine grained, makes weaker assumptions, and allows more scope for empirical methods.

Chalmers has provided a dilemmatic master argument against all forms of the phenomenal concept strategy. This paper explores a position that evades Chalmers's argument, dubbed Type Bb: it is for Type B physicalists who embrace horn b of Chalmers's dilemma. The discussion concludes that Chalmers fails to show any incoherence in the position of a Type B physicalist who depends on the phenomenal concept strategy.

Colours appear to instantiate a number of structural properties: for instance, they stand in distinctive relations of similarity and difference, and admit of a fundamental distinction into unique and binary. Accounting for these structural properties is often taken to present a serious problem for physicalist theories of colour. This paper argues that a prominent attempt by Byrne and Hilbert to account for the structural properties of the colours, consistent with the claim that colours are types of surface spectral reflectance, is (...) unsuccessful. Instead, it is suggested that a better account of the structural properties of the colours is provided by a form of non-reductive physicalism about colour: a naïve realist theory of colour, according to which colours are superficial mind-independent properties. (shrink)

One strategy for blocking Chalmers's overall case against physicalism has been to deny his claim that showing that phenomenal properties are in some sense physical requires an a priori entailment of the phenomenal truths from the physical ones. Here I avoid this well-trodden ground and argue instead that an a priori entailment of the phenomenal truths from the physical ones does not require an analysis in the Jackson/Chalmers sense. This is to sever the dualist's link between conceptual analysis and (...) a priori entailment by showing that the lack of the former does not imply the absence of the latter. Moreover, given the role of the argument from conceptual analysis in Chalmers's overall case for dualism, undermining that argument effectively undermines that case as a whole in a way that, I'll argue, undermining the conceivability arguments as stand-alone arguments does not. (shrink)

A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts (...) are importantly different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience. (shrink)

This paper presents and discusses the most influential attempts to characterize physicalism without postulating relations of identity between the physical and the prima facie non-physical. The first section deals with a possible criticism that these attempts are misguided, since they contradict the physicalist slogan “everything there is physical.” In the second section, I elucidate the different formulations of the physicalist supervenience claim, and argue that none of them consists in an adequate characterization of physicalism. Three reasons are given (...) in favor of this conclusion: their compatibility with forms of dualism ; the fact that the supervenience relation is left unexplained; and Kim’s causal exclusion argument, which asserts that merely supervenient entities must be epiphenomenal. The third section presents the general features of another identity-independent attempt to characterize physicalism, namely realization physicalism. According to this view, tokens of prima facie non-physical types are realized by tokens of strictly physical types performing functional roles that specify the nature of the former. The third section also shows how realization physicalism deals with the objections that make physicalist supervenience claims inadequate for characterizing physicalism. Resumo O artigo apresenta e discute as tentativas mais influentes de caracterizar o fisicalismo sem postular relações de identidade entre o que é físico e o que é prima facie não físico. A primeira seção trata da possível crítica de que essas tentativas são equivocadas, porque contradizem o bordão fisicalista “tudo o que existe é físico”. Na segunda seção, elucido as diferentes formulações da tese fisicalista da superveniência, e argumento que nenhuma delas consiste em uma caracterização adequada do fisicalismo. Três razões são oferecidas em favor dessa conclusão: sua compatibilidade com formas de dualismo ; o fato de que a relação de superveniência é mantida sem explicação; e o argumento de Kim da exclusão causal, segundo o qual entidades meramente supervenientes devem ser epifenomenais. A terceira seção apresenta os aspectos gerais de outra tentativa de caracterizar o fisicalismo independente da identidade, a saber, o fisicalismo de realização. De acordo com essa posição, ocorrências de tipos prima facie não físicos são realizadas por ocorrências de tipos físicos quando estes executam os papéis funcionais que especificam a natureza dos primeiros. A terceira seção também revela como o fisicalismo de realização lida com as objeções que tornam as teses fisicalistas da superveniência inadequadas para a caracterização do fisicalismo. (shrink)

Russellian physicalism is becoming increasingly popular because it promises to deliver what everybody wants, realism and physicalism about consciousness. But Russellian physicalists are not the first to swear on “the promise”, standard Type-B physicalism is a less fanciful view that also claims to give everything and take nothing. In this paper, I argue that our hopes should not be placed on Russellian physicalism because, unlike Type-B physicalism, it cannot explain how phenomenal concepts can (...) reveal the nature of phenomenal properties without weakening its physicalist credentials. The revelation challenge shows that Russellian physicalism is either committed to an anti-realist and self-defeating view of phenomenal concepts or it is physically unacceptable. (shrink)

This paper describes a version of type identity physicalism, which we call Flat Physicalism, and shows how it meets several objections often raised against identity theories. This identity theory is informed by recent results in the conceptual foundations of physics, and in particular clar- ifies the notion of ‘physical kinds’ in light of a conceptual analysis of the paradigmatic case of reducing thermody- namics to statistical mechanics. We show how Flat Physi- calism is compatible with the appearance (...) of multiple realisation in the special sciences, and how and in what sense the special sciences laws are autonomous from the laws of physics, despite the full reductive picture of Flat Physicalism. We compare our view with a recent proposal by William Bechtel that accounts for the appearance of levels in mechanistic explanations. (shrink)

How should ‘the physical’ be defined for the purpose of formulating physicalism? In this paper I defend a version of the via negativa according to which a property is physical just in case it is neither fundamentally mental nor possibly realized by a fundamentally mental property. The guiding idea is that physicalism requires functionalism, and thus that being a type identity theorist requires being a realizer-functionalist. In §1 I motivate my approach partly by arguing against Jessica Wilson's (...) no fundamental mentality constraint. In §2 I set out my preferred definition of ‘the physical’ and make my case that physicalism requires functionalism. In §3 I defend my proposal by attacking the leading alternative account of ‘the physical,’ the theory-based conception. Finally, in §4 I draw on my definition, together with Jaegwon Kim's account of intertheoretic reduction, to defend the controversial view that physicalism requires a priori physicalism. (shrink)

It is often said that there are two varieties of identity theory. Type-identity theorists interpret physicalism as the claim that every property is identical to a physical property, while token-identity theorists interpret it as the claim that every particular is identical to a physical particular. The aim of this paper is to undermine the distinction between the two. Drawing on recent work connecting generalized identity to truth-maker semantics, I demonstrate that these interpretations are logically equivalent. I then argue (...) that each has the resources to resolve problems facing the other. (shrink)

How should thought and consciousness be understood within a view of the world as being through-and-through physical? Many philosophers have proposed non-reductive, levels-based positions, according to which the physical domain is fundamental, while thought and consciousness are higher-level processes, dependent on and determined by physical processes. In this book, Kevin Morris's careful philosophical and historical critique shows that it is very difficult to make good metaphysical sense of this idea - notions like supervenience, physical realization, and grounding all fail to (...) articulate a viable non-reductive, levels-based physicalism. Challenging assumptions about the mind-body problem and providing new perspectives on the debate over physicalism, this accessible and comprehensive book will interest scholars working in metaphysics, philosophy of mind, and philosophy of science.

Token physicalism is often viewed as a modest and unproblematic physicalist commitment, as contrasted with type physicalism. This paper argues that the prevalence of functional individuation in biology creates serious problems for token physicalism, because the latter requires that biological entities can be individuated physically and without reference to biological functioning. After characterizing the main philosophical roles for token physicalism, I describe the distinctive uses of functional individuation in models of biological processes. I then introduce (...) some requirements on token identity claims that arise from a position on individuation and identity known as sortalism. An examination of biological examples shows that these sortalist requirements cannot be plausibly met due to differences between individuation by functional biological criteria and by physical criteria. Even without assuming sortalism, token physicalism faces the more basic problem of excluding functionally irrelevant detail from the individuation of biological tokens. I close by suggesting that the philosophical roles for token identity are better fulfilled by a notion of token composition, which promotes a hierarchical picture of individuality. (shrink)

Though not myself a physicalist, I develop a new argument against antiphysicalist positions that are motivated by zombie arguments. I first identify four general features of phenomenal states that are candidates for non-physical types; these are used to generate different types of zombie. I distinguish two antiphysicalist positions: strict dualism, which posits exactly one general non-physical type, and pluralism, which posits more than one such type. It turns out that zombie arguments threaten strict dualism and some pluralist positions (...) as much as they threaten physicalism—indeed, more so, since such positions need zombies to motivate them as alternatives to physicalism—and that the only pluralist position that escapes zombie arguments has a radically inflated ontology.

The article critically examines Jaegwon Kim’s book Physicalism, or Something Near Enough (Princeton: Princeton University Press, 2005). It recognizes the »near enough type of physicalism« involving functional reduction and covering the relational properties of qualia. Its intrinsic qualites are left out, but since it is qualia’s differences and similarities that matter, i.e. which affect our cognition and behaviour, this is, according to Kim, “no big loss”. While appreciating the book’s effort to offer an intelligible physicalistic theory of (...) the world, the paper concludes that it fails to do so. (shrink)

The distinction between token and type physicalism is a familiar feature of discussion of psychophysical relations. Token physicalism, or ontological physicalism, is the view that every token, or particular, in the spatiotemporal world is a physical particular. It is contrasted with type physicalism, or property physicalism -- the view that every first-order type, or property, instantiated in the spatiotemporal world is a physical property. Token physicalism is commonly viewed as a clear (...) thesis, strictly weaker than property physicalism, strictly stronger than substance physicalism, and as a good statement on its own or in conjunction with other theses of minimal physicalism.[i] It is also generally simply assumed to be true, though Davidson has offered a famous argument for its truth, and some have argued against it. Many of those arguing against it are substance physicalists, indicating that they believe token physicalism to be a strictly stronger view.[ii]. (shrink)

Some of the objections most frequently raised against the thesis of physicalism can be summarized as follows: The notions of the biological and social sciences, as e. g. organic whole and Gestalt, means and ends, leadership and hierarchical order, the entire structure and meaning of these scientific systems, are of a type essentially different from those of physics. Consequently they can not be expressed by means of the mathematical language used by physics, and it is “logically impossible” to (...) reduce these sciences to physics. (shrink)

Two ways are considered of formulating a version of retentive physicalism, the view that in some important sense everything is physical, even though there do exist properties, e.g. higher-level scientific ones, which cannot be type-identified with physical properties. The first way makes use of disjunction, but is rejected on the grounds that the results yield claims that are either false or insufficiently materialist. The second way, realisation physicalism, appeals to the correlative notions of a functional property and (...) its realisation, and states, roughly, that any actual property whatsoever is either itself a physical property or else is, ultimately, realised by instances of physical properties. Realisation physicalism is distinctive since it makes no claims of identity whatsoever, and involves no appeal to the dubious concept of supervenience. After an attempt to formulate realisation physicalism more precisely, I explore a way in which, in principle, we could obtain evidence of its truth. (shrink)

Many authors have taken up the challenge of formulating physicalism as a supervenience thesis. These endeavors have met with varying response, but it seems that the general consensus still remains that a supervenience thesis that is both sufficient and necessary for physicalism has yet to be developed. Terence Horgan¹ and Jaegwon Kim² have most famously argued that supervenience theses are not sufficiently strong for physicalism. Nonetheless, several recent articles suggest that there are philosophers who still hold out (...) hope for some type of supervenience of the mental upon the physical being, if not both sufficient and necessary, at least necessary for physicalism.³ In this paper, I will 1) investigate some of the motivation for finding a supervenience thesis that characterizes physicalism, 2) briefly review the types of supervenience theses that have been proposed as necessary (or necessary and sufficient) for physicalism, and 3) investigate in some detail the recent supervenience thesis proposed by Frank Jackson and expounded upon by Gene Witmer. Jackson, in his recent book, claims to have a supervenience thesis that is both necessary and sufficient for physicalism. (shrink)

The dominant way to define physical entities is by appeal to ideal physics (as opposed to current physics). However, it has been worried that physicalism understood in terms of ideal physics would be too liberal to rule out “psychism”, the view that mentality exists at the fundamental metaphysical level. In this article, I argue that whereas physicalism is incompatible with some psychist cases, such as the case of “phenomenalism” in which ideal physics adopts mental concepts to denote fundamental (...) entities, physicalism should accommodate a certain type of psychist case in which fundamental mental entities are denoted by non-mental concepts in ideal physics. In so doing, I propose a distinctive account of physical entities, which asserts that physical entities are entities denoted by non-mental natural concepts in ideal physics. Physicalism thus understood is expected to be neither too liberal nor too demanding. (shrink)

Larry Hardin has been the most steadfast and influential critic of physicalist theories of color over the last 20 years. In their modern form these theories originated with the work of Smart and Armstrong in the 1960s and 1970s1 and Hardin appropriately concentrated on their views in his initial critique of physicalism.2 In his most recent contribution to this project3 he attacks Michael Tye’s recent attempts to defend and extend color physicalism.4 Like Byrne and Hilbert5, Tye identifies color (...) with the reflecting properties of objects (“reflectance physicalism”). Specifically, the determinate and determinable colors are identified with types of reflectances. (Setting some complications aside, the reflectance of an object is the proportion of light that it reflects at each wavelength in the visible spectrum.) These reflectance types are, in the terminology of Hilbert, anthropocentric—in the terminology of Lewis6, they are not very “natural”. (shrink)

Physicalist epiphenomenalism is the conjunction of the doctrine that tokens of mental events are tokens of physical events and the doctrine that mental events do not exert causal powers by virtue of falling under mental types. The purpose of the paper is to show that physicalist epiphenomenalism, contrary to what many have thought, is not subject to the objections that have been raised against classic epiphenomenalism. This is argued with respect to five such objections: that introspection shows that our mental (...) properties are causally efficacious; that concrete existents and their properties necessarily possess causal powers; that the explanatory and predictive success of psychology implies that psychological properties exist and are causally efficacious; that epiphenomenalism cannot deal with the other minds problem, and that it is unlikely that our mentality does not endow us with evolutionary advantages and therefore it is unlikely that mental properties are not causally efficacious. (shrink)

In this paper I argue that the problem of mental causation can be solved by distinguishing between classificatory mental properties, like being a pain, and instances of those properties.Antireductive physicalism allows only that the former be irreducibly mental. Consequently, properties like being a pain cannot have causal commerce with the physical without violating causal closure. But instances of painfulness, according to the token identity thesis, are identical with various physical tokens and can therefore have causal efficacy in the physical (...) world. Since we expect particular mental phenomena, not types or classes of mental phenomena to be involved in causal interactions, it is argued that antireductive physicalism can explain satisfactorily mental causation, despite the protests of Kim, Sosa, Honderich, and others. Being a mental state of a certain sort may have no causal efficacy, but the intentional and phenomenal properties of such states should, if my argument is correct. (shrink)

The meta-problem of consciousness is the problem of explaining why we believe that there is a hard problem of consciousness. A solution to the former promises to take us one step closer to solving the latter. While many hope for a physicalist realist solution to the meta-problem, I argue that the two prominent physicalist realist positions in the literature, orthodox Russellian and type-B physicalism, cannot deliver a solution. I then introduce a posteriori Russellian physicalism, a Russellian version (...) of the phenomenal concept strategy, and show that it can overcome the difficulties of traditional Russellian and type-B physicalism. If successful, the paper shows that physicalists need not turn to illusionism because the prospects for a physicalist realist answer to the meta-problem are bright. (shrink)

In his (1977) "Anomalous Monism and Kripke's Cartesian Intuitions," Colin McGinn argues that Donald Davidson's anomalous monism is untouched by Kripke's (1980) argument against the identity theory. The type-identity of the physical with the mental may very well fall at the feet of Kripke's powerful arguments, but a token identification, argues McGinn, is left standing due to the simple fact that token physicalism countenances a kind of imagined separation of token mental states with their corresponding token physical states. (...) If McGinn is correct, a full-blooded physicalism is consistent with Kripke's Cartesian intuitions regarding the non-identity of the mental and the physical. But I think McGinn is mistaken. In particular, McGinn misunderstands the nature of an "epistemic counterpart" of a token pain. So contrary to McGinn, token physicalism does not seem to be able to defend against Kripke after all.

Boran Berčić, in the second volume of his recent book "Filozofija" , offers two responses to David Chalmers’s conceivability or modal argument against physicalism. This latter argument aims at showing that zombies, our physical duplicates who lack consciousness, are metaphysically possible, given that they are conceivable. Berčić’s first response is based on the principle of the uniformity of nature that states that causes of a certain type will always cause effects of the same type. His second response (...) is based on the assumption that the basic statements of physicalism in philosophy of mind are or should be contingently true. I argue that if Berčić’s first defence is aimed at the conceivability of zombies, it is unsatisfactory. Moreover, I argue that a quite similar argument, offered by John Perry in his book "Knowledge, Possibility and Consciousness" , is afflicted by a similar problem. Nevertheless, under a more plausible interpretation, Berčić’s argument might be taken to attack the metaphysical possibility of zombies. This version of the argument might be effective and has the merit to point out a so far overlooked link between the discussion of the Chalmers’s conceivability arguments against physicalism and the modal strength of causal links and natural laws. Then, I argue that Berčić’s second defence of physicalism, which cannot be combined consistently with his first one, in any case, should not be formulated in the terms of contingent physicalism.

Most ?theories of consciousness? are based on vague speculations about the properties of conscious experience. We aim to provide a more solid basis for a science of consciousness. We argue that a theory of consciousness should provide an account of the very processes that allow us to acquire and use information about our own mental states ? the processes underlying introspection. This can be achieved through the construction of information processing models that can account for ?Type-C? processes. Type-C (...) processes can be specified experimentally by identifying paradigms in which awareness of the stimulus is necessary for an intentional action. The Shallice (1988b) framework is put forward as providing an initial account of Type-C processes, which can relate perceptual consciousness to consciously performed actions. Further, we suggest that this framework may be refined through the investigation of the functions of prefrontal cortex. The formulation of our approach requires us to consider fundamental conceptual and methodological issues associated with consciousness. The most significant of these issues concerns the scientific use of introspective evidence. We outline and justify a conservative methodological approach to the use of introspective evidence, with attention to the difficulties historically associated with its use in psychology. (shrink)

Supervenience physicalism attempts to combine non-reductionism about properties with a physical determination thesis in such a way as to ensure physicalism. I argue that this attempt is unsuccessful: the specific supervenience relation in question is either strong enough to ensure reductionism, as in the case of strong supervenience, or too weak to yield physical determination, as in the case of global supervenience. The argument develops in three stages. First, I propose a distinction between two types of reductionism, definitional (...) and scientific, a distinction thanks to which we can reply to a standard objection against the ontological reductionism of strong supervenience. Second, I claim that because of "the problem of random distribution," global supervenience needs strengthening to be an adequate relation to capture our physicalistic intuitions; and I show, in accordance with Stalnaker's relevant proof, why a natural strengthening of global supervenience renders it equivalent to strong supervenience. Finally, I argue against Stalnaker about the possibility of a non-reductionist global supervenience. The upshot is that despite appearances, supervenience physicalism is a form of reductive physicalism. (shrink)

A well-known ``overdetermination''argument aims to show that the possibility of mental causes of physical events in a causally closed physical world and the possibility of causally relevant mental properties are both problematic. In the first part of this paper, I extend an identity reply that has been given to the first problem to a property-instance account of causal relata. In the second, I argue that mental types are composed of physical types and, as a consequence, both mental and physical types (...) may be causally relevant with respect to the same physical effect, contrary to the overdetermination argument. In further sections, I argue that mental types have causal powers, consider some objections and reject an alternative version of part-whole physicalism. Throughout I assume that causal relata are tropes and property types are classes of tropes. (shrink)

In this book, Derk Pereboom explores how physicalism might best be formulated and defended against the best anti-physicalist arguments. Two responses to the knowledge and conceivability arguments are set out and developed. The first exploits the open possibility that introspective representations fail to represent mental properties as they are in themselves; specifically, that introspection represents phenomenal properties as having certain characteristic qualitative natures, which these properties might actually lack. The second response draws on the proposal that currently unknown fundamental (...) intrinsic properties provide categorical bases for known physical properties and would also yield an account of consciousness. While there are non-physicalist versions of this position, some are amenable to physicalism. The book's third theme is a defense of a nonreductive account of physicalism. The type of nonreductivism endorsed departs from others in that it rejects all token identity claims for psychological and microphysical entities. The deepest relation between the mental and the microphysical is constitution, where this relation is not to be explicated by the notion of identity. (shrink)

Nonetheless, several recent articles suggest that there are philosophers who still hold out (...) hope for some type of supervenience of the mental upon the physical being, if not both sufficient and necessary, at least necessary for physicalism.3 In this paper, I will 1) investigate some of the motivation for finding a supervenience thesis that characterizes physicalism, 2) briefly review the types of supervenience theses that have been proposed as necessary (or necessary and sufficient) for physicalism, and 3) investigate in some detail the recent supervenience thesis proposed by Frank Jackson and expounded upon by Gene Witmer. Jackson, in his recent book, claims to have a supervenience thesis that is both necessary and sufficient for physicalism. (shrink)
