Ajatus mentaalisesta kausaatiosta – siitä että mentaaliset ominaisuudet, tilat tai tapahtumat aiheuttavat fysikaalisia vaikutuksia, esimerkiksi ruumiinliikkeitä ja käyttäytymistä – on keskeinen osa niin arkiajattelua kuin tieteellistä psykologiaakin. Itsessään se tuntuu lähes latteudelta. Tarkemmassa filosofisessa tarkastelussa se kuitenkin synnyttää huomattavia filosofisia ongelmia (ks. esim. Block 1990; Heal & Mele 1993; Crane 1995).

In this doctoral dissertation I consider, and reject, the claim that recent varieties of non-reductive physicalism, particularly Donald Davidson's anomalous monism, are committed to a new kind of epiphenomenalism. Non-reductive physicalists identify each mental event with a physical event, and are thus entitled to the belief that mental events are causes, since the physical events with which they are held to be identical are causes. However, Jaegwon Kim, Ernest Sosa and others have argued that if we follow the non-reductive physicalist (...) in denying that mental features can be reduced to physical properties, then we must regard mental properties as being causally irrelevant to their bearers' effects, In short, the non-reductive physicalist is said to be committed to the belief that while there are mental causes, they do not cause their effects in virtue of being the types of mental state that they are. It is in this sense that non-reductive physicalists are thought to represent a new form of epiphenomenalism. After a brief survey of the history of epiphenomenalism, and its mutation into the contemporary strain that is believed to afflict non-reductive physicalism, 1 argue against the counterfactual criterion of the sort of causal relevance that we take mental features to enjoy. I then criticize the 'trope' response to the epiphenomenalist threat, and conclude that much of the current debate on this topic is premised on the mistaken belief that there is some variety of causal relevance that is not simply a brand of explanatory relevance. Once this is seen, it will seem much less plausible that mental properties are excluded from relevance to the phenomena of which we typically take them to be explanatory. (shrink)

Plausibly, agents act freely iff their actions are responses to reasons. But what sort of relationship between reason and action is required for the action to count as a response? The overwhelmingly dominant answer to this question is modalist. It holds that responses are actions that share a modally robust or secure relationship with the relevant reasons. This thesis offers a new alternative answer. It argues that responses are actions that can be explained by reasons in the right way. This (...) explanationist answer comes apart from the modalist answer. For it holds that actions are responses to reasons if they are explained by those reasons even if they don’t share a modally robust relationship. Explanationism thus offers a novel way of vindicating the intuition that alternative possibilities don’t matter to responding to reasons and (consequently) free agency. The key dialectical position the thesis develops is that both modalism and explanationism constitute attempts to capture he core type of relationship encoded by the notion of a response. Responses to reasons, at core, involve a non-accidental relationship between reason and action. We can either understand non-accidentality as a modal phenomenon – as a modally robust tracking between two facts. Or we can understand non-accidentality as an explanatory phenomenon – as a special explanatory relationship between two facts. According to my rival explanationist proposal, two facts share a non-accidental relationship iff we can give a unified explanation of why both obtain. Unified explanations are explanations of why [p&q] that cannot be decomposed into two (or more) separate independent explanations of p and of q. Consequently, according to explanationism about responding to reasons, actions are responses to reasons iff those reasons offer a rational explanation of the action that cannot be decomposed into separate independent components.

In this paper I distinguish two types of mental causation, called 'higher-level causation' and 'exploitation'. These notions superficially resemble the traditional problematic notions of supervenient causation and downward causation, but they are different in crucial respects. My new distinction is supported by a radically externalist competitor of the so-called Standard View of mental states, i.e. the view that mental states are brain states. I argue that on the Alternative View, the notions of 'higher-level causation' and 'exploitation' can in combination dissolve (...) the problem of mental causation as standardly discussed. (shrink)

In this paper we present a two-stage argument against Peter Carruthers' theory of phenomenal consciousness. The first stage shows that Carruthers' main argument against first-order representational theories of phenomenal consciousness applies with equal force against his own theory. The second stage shows that if Carruthers can escape his own argument against first-order theories, it will come at the cost of wedding his theory to certain unwelcome implausibilities. discusses Carruthers' argument against first-order representationalism. presents Carruthers' theory of consciousness. presents our argument (...) against Carruthers' theory. sums up.

The Problems of Mental Causation. Functionalism in the philosophy of mind identifies mental states with their dispositional connections with other mental states, perceptions and actions. Many theories of the mind have sailed under the Functionalist flag. But what I take to be essential to Functionalism is that mental states are individuated causally: the reality of mental states depends essentially on their causal efficacy.

The exclusion problem is held to show that mental and physical events are identical by claiming that the denial of this identity is incompatible with the causal completeness of physics and the occurrence of mental causation. The problem relies for its motivation on the claim that overdetermination of physical effects by mental and physical causes is objectionable for a variety of reasons. In this paper, I consider four different definitions of? overdetermination? and argue that, on each, overdetermination in all cases (...) of mental causation either does not occur or is unobjectionable, even when mental and physical events are non-identical. I therefore conclude that the exclusion problem cannot be used as a reason to accept that mental and physical events are identical unless some other definition of? overdetermination? is provided.

Absence of evidence arguments are indispensable to comparative neurobiology. The absence in a given species of a homologous neural architecture strongly correlated with a type of conscious experience in humans should be able to be taken as a prima facie reason for concluding that the species in question does not have the capacity for that conscious experience. Absence of evidence reasoning is, however, widely disparaged for being both logically illicit and unscientific. This paper argues that these concerns are unwarranted. There (...) is no logical barrier to formulating cogent absence of evidence arguments; indeed, accepting such arguments is part of what it is to be committed to falsifiability as a critical aspect of the scientific method. Absence of evidence arguments can always be blocked, however, by assuming that psychological properties are ‘multiply realizable’. While we take multiple realizability to be highly likely at some level of analysis, we argue that it is question-begging to assume that it exists at every level of analysis, and thus it should not automatically be thought to undermine absence of evidence reasoning in the animal consciousness debate. Using the example of pain and focusing on homologies at the level of information processing tasks, we show how, in the science of consciousness, an absence of evidence might well serve as evidence of absence.

The independence problems for functionalism stem from the worry that if functional properties are defined in terms of their causes and effects then such functional properties seem to be too intimately connected to these purported causes and effects. I distinguish three different ways the independence problems can be filled out – in terms of necessary connections, analytic connections and vacuous explanations. I argue that none of these present serious problems. Instead, they bring out some important and over-looked features of functionalism.

In this paper I present an analysis of causal relevance for properties. I believe that most of us are already familiar with the notion of a causally relevant property. But some of us may not recognize it "under that description." So I begin below with some intuitive explanations and some illustrative examples.

The basic form of the exclusion problem is by now very, very familiar. 2 Start with the claim that the physical realm is causally complete: every physical thing that happens has a sufficient physical cause. Add in the claim that the mental and the physical are distinct. Toss in some claims about overdetermination, give it a stir, and voilá—suddenly it looks as though the mental never causes anything, at least nothing physical. As it is often put, the physical does all (...) the work, and there is nothing left for the mental to do. (shrink)

The argument from causal overdetermination is considered to be the shortest route to token monism. It only assumes that:1.Efficacy: Mental events are causes of physical events.2.Closure: Every physical event has a sufficient physical cause.3.Exclusion: Systematic Causal Overdetermination is impossible: if an event x is a sufficient cause of an event y then no event x* distinct from x is a cause of y.4.Identity: Therefore, mental events are physical events.Exclusion does not deny the possibility of two gunmen that fi re at (...) a victim at the same time. But event-dualism is like a systematic fi ringsquad case — whenever I want to raise my arm, my arm is raised, and that is intolerable. (shrink)

In this paper I propose a defense of a posteriori materialism.Problems with a posteriori identity materialism are identified,and a materialism based on composition, not identity, is proposed.The main task for such a proposal is to account for the relationbetween physical and phenomenal properties. Composition does notseem to be fit as a relation between properties, but I offer apeculiar way to understand property-composition, based on somerecent ideas in the literature on ontology. Finally, I propose amaterialist model for the mind-body relation that (...) is able to resistthe attack from conceivability arguments. (shrink)

Epiphenomenalism has had a long historical tradition. It is the view that mental properties are causally inert with respect to the physical world. In this paper, I argue that this tradition faces enormous challenges and needs better arguments to defend its position, and to demonstrate this, I interrogate the strands including computationalism, the idea of the illusion of conscious will, and causal exclusionism.

Multiple realizability (MR) is traditionally conceived of as the feature of computational systems, and has been used to argue for irreducibility of higher-level theories. I will show that there are several ways a computational system may be seen to display MR. These ways correspond to (at least) five ways one can conceive of the function of the physical computational system. However, they do not match common intuitions about MR. I show that MR is deeply interest-related, and for this reason, difficult (...) to pin down exactly. I claim that MR is of little importance for defending computationalism, and argue that it should rather appeal to organizational invariance or substrate neutrality of computation, which are much more intuitive but cannot support strong antireductionist arguments.

Worries about mental causation are prominent in contemporary discussions of the mind and human agency. Originally, the problem of mental causation was that of understanding how a mental substance (thought to be immaterial) could interact with a material substance, a body. Most philosophers nowadays repudiate immaterial minds, but the problem of mental causation has not gone away. Instead, focus has shifted to mental properties. How could mental properties be causally relevant to bodily behavior? How could something mental qua mental cause (...) what it does? After looking at the traditional Problem of Interaction, we survey various versions of the property-based problem and look at proposed solutions to them. (shrink)

Der These des erweiterten Geistes zufolge befinden sich manche mentalen Repräsentationen außerhalb der körperlichen Grenzen der Wesen, zu denen sie gehören. Einer der stärksten Einwände gegen diese These stellt das Argument der Nichtabgeleitetheit von Frederick Adams, Ken Aizawa und Jerry Fodor dar. Dieses Argument setzt voraus, dass genuine mentale Repräsentationen nichtabgeleitete Gehalte haben – ihre semantischen Eigenschaften sind also nicht durch Absichten, Wünsche oder Konventionen konstituiert. Repräsentationen mit nichtabgeleitetem Gehalt finden sich jedoch, so das Argument weiter, nur innerhalb der körperlichen (...) Grenzen mentaler Wesen. Ich werde dafür argumentieren, dass das Argument der Nichtabgeleitetheit scheitert, da es insbesondere bei Tieren externe Repräsentationen gibt, deren Gehalt nichtabgeleitet ist. Dies folgt jedenfalls aus der aussichtsreichsten Theorie nichtabgeleiteter Repräsentationen, der Teleosemantik, und es gibt gute Gründe anzunehmen, dass auch andere naturalistische Gehaltstheorien dieselbe Implikation haben.

The thesis that mental properties are dependent, or supervenient, on physical properties, but this dependence is not lawlike, has been influential in contemporary philosophy of mind. It is put forward explicitly in Donald Davidson's seminal ‘Mental Events.’ On the one hand, Davidson claims that the mental is anomalous, that ‘there are no strict deterministic laws on the basis of which mental events can be predicted and explained’, and, in particular, that there are no strict psychophysical laws. On the other hand, (...) he insists that the mental supervenes on the physical; that ‘mental characteristics are in some sense dependent, or supervenient, on physical characteristics’. (shrink)

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

A comprehensive introduction to the Language of Though Hypothesis (LOTH) accessible to general audiences. LOTH is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, thought is, roughly, the tokening of a representation that has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in (...) syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking. (shrink)

In Zhong (Philos Phenomenol Res 83:129–147, 2011; Analysis 72:75–85, 2012), I argued that, contrary to what many people might expect, the counterfactual theory of causation will generate (rather than solve) the exclusion problem. Recently some philosophers raise an incisive objection to this argument. They contend that my argument fails as it equivocates between different notions of a physical realizer (see Christensen and Kallestrup in Analysis 72:513–517, 2012). However, I find that their criticism doesn’t threaten the central idea of my view. (...) In this paper, I make two separate responses that appeal to two unequivocal notions of physical realizers, respectively. I aim to show that a modified argument that uses either notion would work.

The realization relation that allegedly holds between mental and physical properties plays a crucial role for so-called non-reductive physicalism because it is supposed to secure both the ontological autonomy of mental properties and, despite their irreducibility, their ability to make a causal difference to the course of the causally closed physical world. For a long time however, the nature of realization has largely been ignored in the philosophy of mind until a couple of years ago authors like Carl Gillett, Derk (...) Pereboom, or Sydney Shoemaker proposed accounts according to which realization is understood against the background of the so-called 'causal theory of properties'. At least partially, the hope was to solve the problem of mental causation, in particular the kind of causal exclusion reasoning made famous by Jaegwon Kim, in a way acceptable to nonreductive physicalists. The paper asks whether a proper explication of the realization relation can indeed help explain how physically realized mental properties can be causally efficacious in the causally closed physical world and argues for a negative answer: it is important for the non-reductive physicalist to understand what exactly the realization relation amounts to, but it does not solve the problem of mental causation.

The problem this paper deals with is the problem of how dispositional properties can have causal relevance. In particular, the paper is focused on the question of how dispositions can have causal relevance given that the categorial bases that realise them seem to be sufficient to bring about the effects that dispositions explain. I show first that this problem of exclusion has no general solution. Then, I discuss some particular cases in which dispositions are causally relevant, despite of this exclusion (...) problem. My claim is that dispositions have causal relevance in selection or recruitment processes, when they are converted into teleological functions. (shrink)

Recent years have seen renewed interest in the emergence issue. The contemporary debate, in contrast with that of past times, has to do not so much with the mind–body problem as with the relationship between the physical and other domains; mostly with the biological domain. One of the main sources of this renewed interest is the study of complex and, in general, far-from-equilibrium self-preserving systems, which seem to fulfil one of the necessary conditions for an entity to be emergent; namely, (...) that its causal powers are not predictable from the causal powers of basic physical properties. However, I argue that much of the current emergentism debate has misfired by focusing on the interpretation of self-maintaining systems. In contrast, I claim that if we want to find emergent properties, we should look not at complex systems, but at selection (natural selection, in particular). I argue that selection processes make the causal world ‘exuberant’ by making non-physical functional and relational properties enter the causal web of the world. (shrink)

According to a model defended by some authors, dispositional concepts can be legitimately used in causal explanations, although such a use is not necessary. I argue, however, that there is a kind of use of dispositions in explanations that does not fall within this model: we will miss some explanations if we forsake dispositional concepts and explanations.

In a recent paper, Bird (in: Groff (ed.) Revitalizing causality: Realism about causality in philosophy and social science, 2007 ) has argued that some higher-order properties—which he calls “evolved emergent properties”—can be considered causally efficacious in spite of exclusion arguments. I have previously argued in favour of a similar position. The basic argument is that selection processes do not take physical categorical properties into account. Rather, selection mechanisms are only tuned to what such properties can do, i.e., to their causal (...) powers. This picture seems ultimately untenable in the light of further exclusion problems; but at the same time, it meets our explanatory demands. My purpose is therefore to show that there is a real antinomy with regard to evolved emergent properties. I develop a physicalist exclusion argument and then I go on to consider an argument that seems to establish that evolved emergent properties are causally efficacious, and propose a compatibilist solution. Finally, I very briefly consider what the proposed model may imply for the issue of mental causation. (shrink)

Among philosophers of mind, it is common to assume that at least some mental properties are functional in nature, and that functional properties are second-order properties. In the functionalist literature, the notion of being a second-order property is cashed out in three different ways: (i) in terms of semantic features of characterizations or definitions of properties, (ii) in terms of syntactic features of second-order quantification, and (iii) in terms of a metaphysical criterion, according to which properties are second order if (...) they are properties of first-order properties. It is shown that in the context of functionalism reference to these interpretations is misguided, and it is suggested that the notion of an ordering of properties in this context is best understood as being tied to dependence-relations. (shrink)

In this paper I will discuss Kims powerful explanatory exclusion argument against the causal efficacy of mental properties. Baker and Burge misconstrue Kims challenge if they understand it as being based on a purely metaphysical understanding of causation that has no grounding in an epistemological analysis of our successful scientific practices. As I will show, the emphasis on explanatory practices can only be effective in answering Kim if it is understood as being part of the dual-explanandum strategy. Furthermore, a fundamental (...) problem of the contemporary debate about mental causation consists in the fact that all sides take very different examples to be paradigmatic for the relation between psychological and neurobiological explanations. Even if we should expect some alignment in the explanatory scope of neurobiology and psychology/folk-psychology, there is no reason to expect that all mental explanations are exempted by physical explanations, since they do not in general explain the same phenomena. (shrink)

I aim to reconcile two apparently conflicting theses: (a) Everything that can be explained, can be explained in purely physical terms, that is, using the machinery of fundamental physics, and (b) some properties that play an explanatory role in the higher level sciences are irreducible in the strong sense that they are physically undefinable: their nature cannot be described using the vocabulary of physics. I investigate the contribution that physically undefinable properties typically make to explanations in the high-level sciences, and (...) I show that when they are explanatorily relevant, it is in virtue of their extension (or something close) alone. They are irreducible because physics cannot capture their nature; this is no obstacle, however, to physics' more or less capturing their extension, which is all that it need do to duplicate their explanatory power. In the course of the argument, I sketch the outlines of an account of the explanation of physically contingent regularities, such as the regularities found in most branches of biological inquiry, at the center of which is an account of the nature of contingent, empirical bridge principles.

The debate over physicalism in philosophy of mind can be seen as concerning an inconsistent tetrad of theses: (1) if physicalism is true, a priori physicalism is true; (2) a priori physicalism is false; (3) if physicalism is false, epiphenomenalism is true; (4) epiphenomenalism is false. This paper argues that one may resolve the debate by distinguishing two conceptions of the physical: on the theory‐based conception, it is plausible that (2) is true and (3) is false; on the object‐based conception, (...) it is plausible that (3) is true and (2) is false. the paper also defends and explores the version of physicalism that results from this strategy.

The paper criticizes standard functionalist arguments for multiple realization. It focuses on arguments in which psychological states are conceived as computational, which is precisely where the multiple realization doctrine has seemed the strongest. It is argued that a type-type identity thesis between computational states and physical states is no less plausible than a multiple realization thesis. The paper also presents, more tentatively, positive arguments for a picture of local reduction.

Searle’s celebrated Chinese room thought experiment was devised as an attempted refutation of the view that appropriately programmed digital computers literally are the possessors of genuine mental states. A standard reply to Searle, known as the “robot reply” (which, I argue, reflects the dominant approach to the problem of content in contemporary philosophy of mind), consists of the claim that the problem he raises can be solved by supplementing the computational device with some “appropriate” environmental hookups. I argue that not (...) only does Searle himself casts doubt on the adequacy of this idea by applying to it a slightly revised version of his original argument, but that the weakness of this encoding-based approach to the problem of intentionality can also be exposed from a somewhat different angle. Capitalizing on the work of several authors and, in particular, on that of psychologist Mark Bickhard, I argue that the existence of symbol-world correspondence is not a property that the cognitive system itself can appreciate, from its own perspective, by interacting with the symbol and therefore, not a property that can constitute intrinsic content. The foundational crisis to which Searle alluded is, I conclude, very much alive. (shrink)

‘‘Thus I believe that there is no part of matter which is not—I do not say divisible—but actually divided; and consequently the least particle ought to be considered as a world full of an infinity of different creatures.’’ (Leibniz, letter to Foucher).

Dualism holds that some mental events are fundamental and non-physical. I develop a prima facie plausible causal argument for dualism. The argument has several significant implications. First, it constitutes a new way of arguing for dualism. Second, it provides dualists with a parity response to causal arguments for physicalism. Third, it transforms the dialectical role of epiphenomenalism. Fourth, it refutes the view that causal considerations prima facie support physicalism but not dualism. After developing the causal argument for dualism and drawing (...) out these implications, I subject the argument to a battery of objections. Some prompt revisions to the argument. Others reveal limitations in scope. It falls out of the discussion that the causal argument for dualism is best used against physicalism as a keystone in a divide and conquer strategy. (shrink)

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).

Causal theories of mental content (CTs) ground certain aspects of a concept's meaning in the causal relations a concept bears to what it represents. Section 1 explains the problems CTs are meant to solve and introduces terminology commonly used to discuss these problems. Section 2 specifies criteria that any acceptable CT must satisfy. Sections 3, 4, and 5 critically survey various CTs, including those proposed by Fred Dretske, Jerry Fodor, Ruth Garrett Millikan, David Papineau, Dennis Stampe, Dan Ryder, and the (...) author himself. The final section considers general objections to the causal approach. (shrink)

The formal conception of computation (FCC) holds that computational processes are not sensitive to semantic properties. FCC is popular, but it faces well-known difficulties. Accordingly, authors such as Block and Peacocke pursue a ?semantically-laden? alternative, according to which computation can be sensitive to semantics. I argue that computation is insensitive to semantics within a wide range of computational systems, including any system with ?derived? rather than ?original? intentionality. FCC yields the correct verdict for these systems. I conclude that there is (...) only one promising strategy for semantically-laden theorists: identify special computational systems that help generate their own semantic properties, and then show that computation within those systems is semantically-laden. Unfortunately, the few existing discussions that pursue this strategy are problematic. (shrink)

According to the received view in philosophy of mind, mental states or properties are _realized_ by brain states or properties but are not identical to them. This view is often called _realization_ _physicalism_. Carl Gillett has recently defended a detailed formulation of the realization relation. However, Gillett’s formulation cannot be the relation that realization physicalists have in mind. I argue that Gillett’s “dimensioned” view of realization fails to apply to a textbook case of realization. I also argue Gillett counts as (...) realization some cases that should not count if realization physicalism is to be distinguished from its competitors in the usual ways. I conclude that the relation described by Gillett cannot be realization. (shrink)

Two strains of interventionist responses to the causal exclusion argument are reviewed and critically assessed. On the one hand, one can argue that manipulating supervenient mental states is an effective strategy for manipulating the subvenient physical states, and hence should count as genuine causes to the subvenient physical states. But unless the supervenient and subvenient states manifest some difference in their manipulability conditions, there is no reason to treat them as distinct, which in turn goes against the basic assumption of (...) nonreductive physicalism. On the other hand, one can preserve the distinction between the two by introducing asymmetric manipulability conditions that the supervenience thesis entails. But this response can be used to argue that mental causes never have physical effects. However, this argumentation can also be used to show that mental causes can have mental effects. (shrink)

The paper defends Functionalism against the charge that it would make mental properties inefficacious. It outlines two ways of formulating the doctrine that mental properties are Functional properties and shows that both allow mental properties to be efficacious. The first (Lewis) approach takes functional properties to be the occupants of causal roles. Block [1990] has argued that mental properties should not be characterized in this way because it would make them properties of the ?implementing science?, e. g. neuroscience. I show (...) why this is not a problem. The second way of formulating the doctrine takes functional properties to be causal role properties. I claim that mental properties so understood would only be inefficacious if a law-centred rather than a property-centred approach is adopted to the introduction of efficacy into the world. I develop a property-centred account that explains how mental properties can be efficacacious without introducing systematic overdetermination. At the close, I provide a better characterization of the difference between these two approaches and offer an explanation as to why my way of resolving the problems has been missed. (shrink)

This paper focuses on an influential line of response to the exclusion problem for nonreductive physicalism, one defended with the most subtlety by Karen Bennett. According to this line of thought, a successful nonreductive response to the exclusion problem, a response that allows one to maintain each of the core components of nonreductive physicalism, may consist in showing that the manner in which the effects of mental causes also have distinct and sufficient physical causes is disanalogous to other types of (...) cases in which an effect may have distinct sufficient causes. After laying out the formulation of the problem that Bennett endorses, along with her response to the problem, I offer an initial critique of this response insofar as it is couched in terms of her preferred formulation. I then present a general critique of disanalogy-style responses to the exclusion problem. I argue that extant implementations of this strategy are at best underdeveloped, and suggest that lack of clarity in the use of “overdetermination” may function to mask the shortcomings of this strategy. While others have questioned the details of such responses, the worries that I raise concern the very logic of the exclusion problem and how such responses fit into this logic. (shrink)

The type-type reductive identity of the mental to the physical was once the dominant position in the mental causation debate. In time this consensus was overturned, largely due to its inability to handle the problem of multiple realizability. In its place a nonreductive position emerged which often included an adherence to functionalism. Functionalism construes mental properties as functional states of an organism, which in turn have specific physical realizers. This nonreductive form of functionalism, henceforth called role functionalism, has faced a (...) number of criticisms itself. Chief among these is the concern that the realizer of the functional role is causally sufficient, so the role property does not make a contribution of its own. In this paper I argue that there is a way for unreduced functional properties to play a role after all. This is done by conceiving of functional properties as higher level functional properties of a macro system which determine that its realizers will play the roles that they play. (shrink)

Jaegwon Kim argues that unreduced mental causes are excluded from efficacy because physical causes are sufficient in themselves. One response to this causal exclusion argument is to embrace some form of overdetermination. In this paper I consider two forms of overdetermination. Independent overdetermination suggests that two individually sufficient causes bring about one effect. This model fails because the sufficiency of one cause renders the other cause unnecessary. Dependent overdetermination suggests that a physical cause is necessary and sufficient for a given (...) effect, but it necessitates a mental cause of the effect as well. This model fails because the necessity of the mental cause renders the physical cause individually insufficient. (shrink)
