Qualia are the elements of phenomenal consciousness -- the raw feels which constitute what it is like to be in a conscious mental state. Some claim that qualia are epiphenomenal properties -- mere by-products of brain function which are causally inert. Though this is an implausible theory, it is difficult to show that it is false. Here I present an ad hominem argument -- the argument from coincidence -- which shows that epiphenomenalism about qualia is explanatorily (...) deficient because it leaves unexplained a highly improbable state of affairs, and so we have good reason to suppose that qualitative properties must be causally efficacious, and must be so in virtue of their qualitative nature.

Agent causation presupposes that actions are behaviors under the causal control of the agent’s mental states, its beliefs and desires. Here the idea of conscious causation in causal explanations of actions is examined, specifically, actions said to be the result of conscious efforts. Causal–functionalist theories of consciousness purport to be naturalistic accounts of the causal efficacy of consciousness. Flanagan argues that his causal–functionalist theory of consciousness satisfies naturalistic constraints on causation and that his causal efficacy thesis is compatible with (...) results of Libet’s experiments on conscious causation. First, the notions of conscious effort and conscious causation are analyzed with respect to the project of naturalizing the mind, that is, the attempt to assimilate folk-psychological explanation to the causal model of explanation in the natural sciences. It is argued that a serious obstacle for any naturalist program is that mental states are individuated by their semantic content, not the mechanistic, physical properties of their neural state instantiations. In particular, it is argued that explanation by reference to mental state content yields not a causal but an interpretive or rationalizing account of action in which the question of causal efficacy is irrelevant. Then, Flanagan’s causal–functionalist theory of consciousness is critically assessed; specifically his interpretations of Libet’s negative experimental results on the causal efficacy of consciousness are diagnosed and disputed. It is contended that Flanagan misinterprets the results of Libet’s consciousness experiments and that his functionalist concept of consciousness fails to yield an adequate explanation of the alleged causal efficacy of consciousness. Finally, his thesis is countered with other experimental results that appear to favor an epiphenomenalist view over the causal efficacy account of consciousness. (shrink)

Nonreductivist physicalists are increasingly regarded as unwitting epiphenomenalists, since their refusal to reduce mental traits to physical properties allegedly implies that even if there are mental causes, none of them produces its effects by virtue of its being a type of mental state. I examine and reject a reply to this concern that relies on the idea of ​​"tropes". I take the failure of the tropes-based model of causal relevance to illustrate a confusion at the (...) heart of the notion of causal relevance, a notion that is central to the critique of non-reductive physicalism. I aim to dispel the idea that non-reductive physicalism is committed to epiphenomenalism. (shrink)

In respect of the question whether mental properties, i.e. contents of mental states, are causally relevant the distinction between type and token physikalism and externalism and their consequences concerning the problems of property dualism and content epiphenomenalism are sketched. Fodor's theory - a functionalist version of token physikalism - is presented and criticized. Distinguishing between naming a causally relevant property and quantifying over it a solution to the threat of epihenomenalism is suggested, and finally Davidson's (...) Anomalous Monism is defended.

This paper responds to critical commentaries on my book, Perceiving Reality (OUP, 2012), by Laura Guerrero, Matthew MacKenzie, and Anand Vaidya. Guerrero focuses on the metaphysics of causation, and its role in the broader question of whether the ‘two truths’ framework of Buddhist philosophy can be reconciled with the claim that science provides the best account of our experienced world. MacKenzie pursues two related questions: (i) Is reflexive awareness (svasaṃvedana) identical with the subjective pole of a dual-aspect cognition or are (...) there alternative, perhaps better, ways of understanding this self-intimating character of mental states? (ii) Is perception constitutively intentional or is it representational? Vaidya argues that, in so far as Husserlian phenomenology and Buddhism differ in terms of their fundamental ontological commit- ments, they must be incompatible, thus rendering any cross-cultural philosophical project that seeks their rapprochement tenuous. One of my aims in Perceiving Reality is to show how accounts of perception informed by metaphysical realism can be problematic on both metaphysical and epistemological grounds, especially when relying on conceptions of consciousness that ignore its properly phenomenological features.

The purpose of this paper is to address a well-known dilemma for physicalism. If mental properties are type identical to physical properties, then their causal efficacy is secure, but at the cost of ruling out mentality in creatures very different to ourselves. On the other hand, if mental properties are multiply realizable, then all kinds of creatures can instantiate them, but then they seem to be causally redundant. The causal exclusion problem depends on the (...) widely held principle that realized properties inherit their causal powers from their realizers. While this principle holds for functional realization, it fails on a broader notion of realization that permits the realization of complex qualitative properties such as spatial and temporal patterns. Such properties are best seen as dependent powerful qualities, which have their causal roles in virtue of being the qualities they are, and do not inherit powers from their realizers. Recent studies have identified one such property—neural synchrony—as a correlate of consciousness. If synchrony is also partially constitutive of consciousness, then phenomenal properties are both multiply realizable and causally novel. I outline a version of representationalism about consciousness on which this constitution claim holds. (shrink)

Chapter 1 is devoted to taking care of some preliminary issues. I begin by distinguishing those states of awareness in virtue of which we’re acquainted with the phenomenal characters of our experiences from those states of awareness some claim are at the very nature of experience. Then I reconcile the idea that experience is transparent with the claim that we can be acquainted with phenomenal character. -/- In Chapter 2 I set up a dilemma that is the (...) primary focus of the dissertation. In the first part of this chapter I argue that phenomenal acquaintance has three key features, what I call its ‘directness’, ‘thickness’, and ‘infallibility’. In the second part I argue, however, that it’s really quite puzzling how thoughts about phenomenal character (or any thoughts, for that matter) could have them. In the next two chapters I consider how we might resolve the dilemma described above. -/- I begin in Chapter 3 by considering an account of phenomenal acquaintance inspired by Bertrand Russell’s discussion of acquaintance. The general idea here is to excise mental representation from phenomenal acquaintance, and I ultimately reject the proposal. -/- Chapter 4 is the core chapter of the dissertation. In it I propose an account of phenomenal acquaintance that doesn’t excise mental representation. My account is comprised of three theses. First, token experiences are complex and have instances of phenomenal properties as components. Second, instances of phenomenal properties are mental representations, and they represent themselves. Third, the attention relevant to phenomenal acquaintance is underwritten by self-representation. I argue that my account explains how phenomenal acquaintance is direct, thick, and infallible, thereby resolving our dilemma. -/- I argue in Chapter 5 that my account of phenomenal acquaintance explains why there is an explanatory gap between the phenomenal and non-phenomenal truths. Accordingly, I conclude that the explanatory gap doesn’t pose a problem for physicalism. Here I implement what has come to be called the ‘phenomenal concept strategy’ for responding to the challenge posed by the explanatory gap. (shrink)

Like all causal theories in philosophy, the causal theory of action is plagued by the problem of deviant causal chains. I have proposed a solution on the basis of the assumption that mental states and events are causally efficacious in virtue of their contents. This solution has been questioned by Torbjörn Tännsjö (2009). First, I will reply to the objection, and then I will discuss Tännsjö’s alternative.

This paper defends a novel account of how we introspect phenomenal states, the Demonstrative Attention account (DA). First, I present a set of necessary and sufficient conditions for phenomenal state introspection which are not psychological, but purely metaphysical and semantic. Next, to explain how these conditions can be satisfied, I describe how demonstrative reference to a phenomenal content can be achieved through attention alone. This sort of introspective demonstration differs from perceptual demonstration in being non-causal. DA nicely (...) explains key intuitions about phenomenal self-knowledge, makes possible an appealing diagnosis of blindsight cases, and yields a highly plausible view as to the extent of our first-person epistemic privilege. Because these virtues stem from construing phenomenal properties as non-relational features of states, my defense of DA constitutes a challenge to relational construals of phenomenal properties, including functionalism and representationalism. And I provide reason to doubt that they can meet this challenge. (shrink)

In Physical Realization, Sydney Shoemaker considers the question of how physicalism can be true: how can all facts about the world, including mental ones, be constituted by facts about the distribution in the world of physical properties? Physicalism requires that the mental properties of a person are 'realized in' the physical properties of that person, and that all instantiations of properties in macroscopic objects are realized in microphysical states of affairs. Shoemaker offers an account (...) of both these sorts of realization, one which allows the realized properties to be causally efficacious. He also explores the implications of this account for a wide range of metaphysical issues, including the nature of persistence through time, the problem of material constitution, the possibility of emergent properties, and the nature of phenomenal consciousness.

The object of this paper is to discuss several issues raised by Fred Dretske’s account of the causal efficacy of content, as given in his book Explaining Behavior. To warrant the causal efficacy of folk-psychological properties while keeping attached to a naturalistic framework, Fred Dretske proposes that these properties are causes of a peculiar type, what he calls structuring causes. Structuring causes are not postulated ad hoc, to somehow account for the causal efficacy of content. Dretske claims that (...) we independently need this dualism of causes to make sense of some of our (not necessarily involving mental states) causal explanations. Even if this variety of dualism is not untenable from a openly-minded physicalistic viewpoint, it seems for several reasons preferable to establish that content properties are causally efficacious in the same sense that physical properties are. The main point I will try to make in this paper is a metaphysical one, namely, that Drestke’s structuring causes are causes of a more ordinary kind. I will try to show that we can make sense of the phenomena that structuring causes are introduced to account for in more conservative terms, having only recourse to the material we must anyway posit to understand ordinary causal explanations.

In discussions on mental causation and externalism, it is often assumed that extrinsic, or relational, properties cannot have causal efficacy. In this paper I argue that this assumption is based on a category mistake, in that causal efficacy (dependence among events or states of affairs) is confused with causal influence (persistence of and interaction among objects). I then argue that relational properties are indeed causally efficacious, which I explain with the help of Dretske's notion of a (...) 'structuring cause'. (shrink)

This paper argues that Twin Earth twins belong to the same psychological natural kind, but that the reason for this is not that the causal powers of mental states supervene on local neural structure. Fodor’s argument for this latter thesis is criticized and found to rest on a confusion between it and the claim that Putnamian and Burgean type relational psychological properties do not affect the causal powers of the mental states that have them. While it is (...) true that Putnamian and Burgean type relational psychological properties do not affect causal powers, it is false that no relational psychological properties do. Examples of relational psychological properties that do affect causal powers are given and psychological laws are sketched that subsume twins in virtue of them instantiating these relational properties rather than them sharing the narrow contents of their thoughts.

Let’s consider the following paradox (Fodor [1989], Jackson and Petit [1988] [1992], Drestke [1988], Block [1991], Lepore and Loewer [1987], Lewis [1986], Segal and Sober [1991]): i) The intentional content of a thought (or any other intentional state) is causally relevant to its behavioural (and other) effects. ii) Intentional content is nothing but the meaning of internal representations. But, iii) Internal processors are only sensitive to the syntactic structures of internal representations, not their meanings. Therefore it seems that if (...) we want to defend the idea -absolutely plausible from an intuitive point of view- that mental / intentional states are causally responsible for behavioural outputs and we want to do it on the physicalist basis of any scientific methodology, we will have to give up the conviction that such intentional states qua intentional, i. e. as having a particular meaning, are the ones causally responsible for our behaviour. The path that takes us to mental epiphenomenalism is clear: 1) the causal powers of any event are completely determined by its physical properties; 2) although intentional properties supervene on physical properties, they can’t be identified with them; 3) intentional properties, as intentional, are not causally responsible for behaviour, because they don’t take part in the causal powers of the states to which they belong, i. e., intentional properties are epiphenomenal. Let’s consider now a different yet parallel position to the one just described. There is an important debate in cognitive science about whether the class of mechanisms to which we belong and which the computational modelling project of cognitive processes refers to is best represented by classical or connectionist approaches (McClelland, Rumelhart et. al [1986], Smolensky [1987] [1988], Fodor and Pylyshyn [1988], Pinker and Prince [1988], Clark [1989], Ramsey, Stich and Rumelhart [1991], Clark and Karmiloff-Smith [forthcoming]).In classical, serial processing models, information is encoded in terms of rules that have a linguistic character. In connectionist or parallel distributed processing (PDP) models, the causal relationships among the units that constitute the system determine how the information is processes by the network, although these units don’t have a direct semantic interpretation. But, for both, classical and connectionist models, all the computations can be explained without any reference to the content of the processed information, i.e., in both cases the properties that seem to be responsible for the system’s behaviour are ultimately physical properties nor intentional ones. This situation mirrors thus, within cognitive science, the philosophical discussion concerning the causal efficacy of semantic properties. Now, if in this debate we opt for the classical paradigm, there is a way of finding a solution to the computational version of the epiphenomenalism paradox. This solution is based mainly on the notion of supervenience or, more precisely, on the notion of mereological supervenience (Kim [1984] [1988])1 . The idea of intentional properties supervening on physical properties makes sense within the classical context because there exists an easily isolable supervenience base comprising the syntactic items in the socalled language of thought. But, what happens if we opt for the connectionist paradigm?. The situation here doesn’t seem to favour the use of the same supervenience strategy. For it has been argued (Ramsey, Stich and Garon [1991]) that beliefs, desires, and other mental states are nor, in the connectionist paradigm, individuable as weight or activation states of the system. This is because information is encoded by the network in distributed and superpositional representations, i.e., there are no straightforwardly isolable vehicles at the physical level that can be identified as the articulated supervenience base on which the semantic properties supervene2 . If this is true, then the connectionist not only loses the battle against epiphenomenalism but more drastically, seems to offer a standing invitation to eliminativism, since talk of beliefs and desires, etc. now seems to be floating free of any acceptable scientific underpinning, i.e., she has lost the necessary theoretical apparatus for supporting the intuitive idea that propositional attitudes -beliefs, desires and any mental states with semantic content- are physically realized. This second line of argumentation doesn’t take us to a paradox but to a dilemma: either we accept eliminativism, if connectionist hypothesis are correct or we defend the causal efficacy of mental states with semantic content by showing that, after all, connectionist networks are not plausible cognitive models (Davies [1991]). From my point of view, however, both lines of argumentation need to be revised. The aim of this paper is to find an account of the causal efficacy of content that avoids the aforementioned epiphenomenalist objections and that doesn’t require the discovery of inner symbols in the computational modelling of such contentful mental states. In short, the aim is to find a meeting point where a philosophical story about content and cause and the connectionist computational model can be brought together (Cfr. Clark [1989]). (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.

In lieu of an abstract, here is a brief excerpt of the content:Wittgenstein on Non-Mediative CausalityJames C. KlaggeIn the late autumn of 1947 Wittgenstein dictated a selection of manuscript material to a typist1 that contains some remarks so striking that they merit extensive quotation:903. No supposition seems to me more natural than that there is no process in the brain correlated with associating or with thinking; so that it would be impossible to read off thought-processes from brain-processes. I mean this: (...) if I talk or write there is, I assume, a system of impulses going out from my brain and correlated with my spoken or written thoughts. But why should the system continue further in the direction of the centre? Why should this order not proceed, so to speak, out of chaos? The case would be like the following—certain kinds of plants multiply by seed, so that a seed always produces a plant of the same kind as that from which it was produced—but nothing in the seed corresponds to the plant which comes from it; so that it is impossible to infer the properties or structure of the plant from those of the seed that it comes out of—this can only be done from the history of the seed. So an organism might come into being even out of something quite amorphous, as it were causelessly; and there is no reason why this should not really hold for our thoughts, and hence for our talking and writing. (Zettel 608)904. It is thus perfectly possible that certain psychological phenomena cannot be investigated physiologically, because physiologically nothing corresponds to them. (Z 609)905. I saw this man years ago; now I have seen him again, I recognize him, I remember his name. And why does there have to be a cause of this remembering in my nervous system? Why must something or other, whatever it may be, be stored-up there in any form? Why must a trace have been left behind? Why should there not be a psychological regularity to which no physiological regularity corresponds? If this upsets our concepts of causality, then it is high time they were upset. (Z 610) [End Page 653]906. The prejudice in favor of psycho-physical parallelism is also a fruit of the primitive conception of grammar. For when one admits a causality between psychological phenomena, which is not mediated physiologically, one fancies that in doing so one is making an admission of the existence of a soul alongside the body, a ghostly soul-nature. (cf. Z 611)909. Why should not the initial and terminal states of a system be connected by a natural law, which does not cover the intermediary state? (Only don’t think of efficacy/influence [Wirkung]!) (Z 613)918. …Well—but now that the structure of the eye is known—how does it come about that we act, react, in this way? But must there be a physiological explanation here? Why don’t we just leave explaining alone?—But you would never talk like that, if you were examining the behavior of a machine!—Well, who says that a living creature, an animal body, is a machine in this sense?— (Z 614)Lest you think, or hope, these ideas were just a passing fancy of Wittgenstein’s, it is worth noting that these passages were among the ones that he cut from this typescript to save in a box and rearrange and perhaps revise for future use. They were published posthumously as Zettel.2What are we to make of these striking ideas? Do they hint at “mystical vitalism”? Is there an intellectual trajectory along which they can be located and appreciated, even if perhaps ultimately rejected? Or is he simply making a “natural” objection to reductionism about memory?3In an earlier publication I briefly offered a motivation for these views,4 but I now have more to say and wish to try again. Earlier I saw these passages primarily in relation to Wittgenstein’s other views about mental phenomena, but I now think something can be gained by seeing them in relation to his views about causality. Unfortunately causality is not a topic about which Wittgenstein had... (shrink)

At the core of the essay that follows is a set of intuitions that distinguish the mental and subjective from the public and objective. I call these intuitions Cartesian intuitions even though Descartes himself ignored some of them. I argue that some of them survive the best efforts of critics to explain them away. This, I contend, is the basis of the mind-body problem, which should be seen as a paradox, in which both materialist and dualist lines of argument (...) seem conclusive. My aim is thus to clarify and to bolster what I call the neo-Cartesian half of the mind-body paradox, to show that there really is a paradox, one that remains with us, undissolved. ;I use two forms of arguments to accomplish this. One is the Knowledge Argument, according to which there are certain things which you can know everything physical about but not know everything about and which, because of that, make physicalism false. The Knowledge Argument says that your having this extra knowledge depends on the existence of special properties called qualia, which are supposed to be separate from any physical or functional properties. I argue that the Knowledge Argument is what survives from Descartes's original critique of materialism. I defend the Knowledge Argument, or at least I defend the claim that it has not so far been refuted. ;The other form of argument is the Absent Qualia Argument. I use it further to support the case against functionalism, the approach to the mind according to which mental states are definable by their causal relations to behaviors, perceptions, and each other. Against this position, I argue that there might be so-called absent qualia states which filled the causal roles of some of our genuine mental states but did not look or feel like anything. The functionalist response to this position is that since absent qualia states cause the same beliefs as genuine states do we could never know whether we were having real states or absent qualia replicas. I argue that there is no such skeptical problem. ;At the heart of both arguments is an account of our direct reference to our own phenomenal states. Critics of the Knowledge Argument have argued that the Cartesian intuitions the argument exploits can be explained away as a result of two distinct forms of reference: roughly, the direct reference distinctive to the mental, the descriptive reference distinctive to our neurophysiological talk. But I argue that we could not refer directly to our phenomenal states unless we did so by way of properties distinct from any neurophysiological properties. Critics of the Absent Qualia Argument can argue that our direct reference to phenomenal states requires mental processing with phenomenal aspects, processing that necessarily runs outside any causal role that might be shared with absent qualia replicas. These side-effects mean that absent qualia are impossible in us. I grant that but argue that this would not rule out the possibility of absent qualia in nonsentient creatures. They might be similar enough to have states with identical causal roles to our phenomenal states; but since they would be free of experience, there would be no chance for the side-effects that make absent-qualia states impossible to realize in us.

Disposition terms, such as 'cowardice,' 'fragility' and 'reactivity,' often appear in explanations. Sometimes we explain why a man ran away by saying that he was cowardly, or we explain why something broke by saying it was fragile. Scientific explanations of certain phenomena feature dispositional properties like instability, reactivity, and conductivity. And these look like causal explanations - they seem to provide information about the causal history of various events. Philosophers such as Ned Block, Jaegwon Kim, Elizabeth Prior, Robert Pargetter, (...) and Frank Jacksonl have suggested reasons for thinking that dispositions are causally inert. I call this the "Inert Dispositions View." According to this view, the glass's fragility was not responsible for its breaking; the man's cowardice was causally impotent as he fled. The Inert Dispositions View would call many of the explanations we give into question. By employing a disposition in an explanation, we might have thought we were giving a causal explanation of the event. Perhaps we took ourselves to be explaining an effect with some feature of its cause that was responsible for the effect. However, if dispositions are causally inert, we are explaining the event in some other way, or not really explaining it at all. The Inert Dispositions View suggests that something is amiss with many scientific explanations. If properties like conductivity and volatility are causally inert, it is not clear how appealing to them provides us with information about why certain phenomena occur. This is especially problematic if one thinks, as some do, that the fundamental properties that scientists attribute to the ultimate constituents of matter -- things like force, mass, charge, impenetrability -- are dispositional. If, as Simon Blackburn says, "science finds only dispositional properties all the way down,"2 and if dispositions are causally inert, it would seem that science does not provide us with real causal explanations. The Inert Dispositions View implies that there is something amiss with psychological explanations as well. At least some psychological states are dispositional -- being courageous or shy, being such that you would accept a drink if you were offered one. On some views, all mental states are like dispositions, since having a mental state is a matter of having some brain state or other that performs a certain causal role. If mental properties are relevantly similar to dispositions, and dispositions are inert, then mental properties make no difference to what a body does. However, it is natural to think that my believing and desiring certain things has much to do with my body moving in certain ways. It would take powerful arguments to cast these beliefs into serious doubt. In this paper, I defend the causal efficacy of dispositions against two types of arguments that l call "Analyticity Arguments" and "No Work Arguments." According to Analyticity Arguments, there is an analytic or necessary connection between a disposition and its manifestation, and this goes to show that there is no causal connection. I argue, on the contrary, that it shows no such thing. According to No Work arguments, manifestations of dispositions already have sufficient causes, and so there is "no work" for dispositions to do. I claim that these arguments rest on some questionable assumptions. (shrink)

According to Karen Neander’s causal-informational teleosemantics, the contents of perceptual states depend on the etiological response functions of sensory-perceptual systems. In this paper, I argue that this theory is, despite its virtues, unable to explain how humans and other animals are capable of perceiving properties with which no sensory-perceptual system has ever been confronted. After rejecting Neander’s own proposal in terms of second-order similarity and a proposal inspired by Ruth Millikan in terms of simplicity, I offer a solution which (...) equates functions with manifestations of dispositions that made a difference to evolutionary success. My suggestion is able to generate determinate and plausible contents for new perceptual states while still preserving the idea that etiological functions explain evolutionary success. (shrink)

I draw attention to an ambiguity of the expression ‘phenomenal consciousness’ that is an avoidable yet persistent source of conceptual confusion among consciousness scientists. The ambiguity is between what I call phenomenality and what I call conscious states, where the former denotes an abstract property and the latter denotes a phenomenon or class of its instances. Since sentences featuring these two terms have different semantic properties, it is possible to equivocate over the term ‘consciousness’. It is also possible (...) to fail to distinguish between statements that are true about conscious states in virtue of their phenomenality, and statements that are true in virtue of other properties of conscious states. I review empirically informed arguments by scientists Bernard Balleine and Anthony Dickinson, Stevan Harnad, and Jeffrey Alan Gray, arguing that each of them makes errors based on the ambiguity. I conclude with some tentative suggestions for avoiding further confusion about the ambiguity. (shrink)

Despite the progress made in studying the observable exteriors of conscious processes, which are reflected in the neural correlates of consciousness (NCC), there are still no satisfactory answers to two closely related core questions. These are the question of the origin of the subjective, phenomenal aspects of consciousness, and the question of the causal mechanisms underlying the generation of specific phenomenal states. In this article, we address these questions using a novel variant of cosmopsychism, a holistic form of (...) panpsychism relying on the central idea that the universe is imbued with a ubiquitous field of consciousness (UFC). This field is understood as a foundational dual-aspect component of the cosmos, the extrinsic appearance of which is physical in nature and the intrinsic manifestation of which is phenomenological in nature. We argue that this approach brings a new perspective into play, according to which the organizational characteristics of the NCC are indicative of the brain’s interaction with and modulation of the UFC. Key insights from modern physics suggest that the modulation mechanism is identical with the fundamental mechanism underlying quantum systems, resulting in the conclusion that a coherently oscillating neural cell assembly acquires phenomenal properties by tapping into the universal pool of phenomenal nuances predetermined by the UFC, or more specifically, by entering into a temporary liaison with the UFC and extracting a subset of phenomenal tones from the phenomenal color palette inherent in the basic structure of the UFC. This hypothesis is supported by a substantial body of empirical evidence. (shrink)

In my dissertation, "Psychosemantics and its Thematic Duality", I have examined Fodor, Dretske and Millikan's psychosemantic approaches to meaning and mind. The focus is to disclose the fact that there is a thematic duality with which psychosemantics begins and also ends. Psychosemantics is committed to the belief that psychological states and processes are not fully explained unless their semantic properties are grasped. For, according to psychosemantics, semantic properties are causally efficacious in our mental transactions--cognition is best (...) described as semantic causation. To say that semantic properties are causally efficacious is intentional realism. To say that semantic properties are physical properties is physicalism. Psychosemantics wants to build intentional realism under physicalism or physicalism under intentional realism. The duality thesis is that intentional realism and physicalism have failed to be unified in psychosemantics. ;The dissertation has six chapters plus a short introduction. Chapter 1: "What is psychosemantics?" provides a general characterization of psychosemantics. Chapter 2: "Dretske's proof of mental causation" examines the problems in Dretske's proof of mental causation. Chapter 3: "Dual Contents and Fodor's Representational Theory of Mind" argues for the duality thesis in general by criticizing Fodor's representational theory of mind in specific. Chapter 4: "Mental Causation: Causal Efficacy and Causal Relevance" criticizes mental causation thesis from a broad perspective. Chapter 5: "Millikan's Biosemantics and its Thematic Duality" argued that Millikan's biosemantics also fails to bring physicalism and intentional realism together. Chapter 6: "Psychological Explanation" is the conclusion. (shrink)

A pigeon has been conditioned to peck at red objects and has also been conditioned to peck at triangular objects. The pigeon is now presented with a red triangle and pecks. In virtue of which of the object's properties did the pigeon peck? I argue that the disjunctive property "red or triangular" best answers this question and that this in turn gives us reason to admit such disjunctive properties to our ontology. I also show how the criterion (...) for causal efficacy that I employ, expressed in terms of counterfactual conditionals, works to preclude spurious disjunctive properties from counting as efficacious.

According to the thesis of powerism, our world is pervaded by causal powers which are metaphysically basic. The aim of this paper is to defend the existence of the self, defined as a substantial entity, and its mental powers. This claim, which may seem a bold one, should not be deemed as inconsistent with scientific evidence. In fact, this approach does not ignore empirical knowledge, but is not bound only to it in order to understand entities, properties, and (...) the relationship between them. Aristotelian powerism may show that the self, as the subject of one’s mental acts, is a substance that has an essential nature. Firstly, we shall analyze the immediate evidence we have in support of the existence of the self as a substantial entity. We will show that the self is a substance because it possesses an essential character, i.e. an individual essence. We will take into account the Aristotelian perspective of substance, trying to show how the presence of a necessary property that makes every subject identical to itself and the phenomenal features of one’s private experience point to the existence of a substantial entity that corresponds to the self. Secondly, we will try to justify the adoption of a metaphysical theory of causation based on powers, analyzing it in comparison with the main competing theories, namely hypotheticalism and nomism. Then, we shall proceed to show the causal properties of the substance in question, namely the mental powers. In fact, thirdly, we will embrace the thesis of powerism by defending the existence of a set of mental powers that should be attributed to the self. We will describe the main features of mental powers and we will show that they are conceivable as the pure intentional acts we perform by directing an intentional state towards an intentional object. In this way we show how a classic problem of philosophy of mind, relevant to science as well, can be addressed in an original way by a metaphysical approach involving powers. (shrink)

Emergentists such as Samuel Alexander and C. Lloyd Morgan held that the mental is causally efficacious, supervenes on the physical, but does so mysteriously. We must accept the emergent mind, in Alexander's phrase, with "natural piety". Emergentism emerged late last century and all but disappeared in the twentieth. This dissertation attempts to revive the position. ;To explain psycho-physical supervenience is to provide a proof of the mental facts from the physical facts, such that mental vocabulary only (...) occurs in the proof in the form of a priori bridge principles connecting mental goings on with the physical facts. Offering a proof of the mental facts from the physical facts would be one way to justify supervenience, thus simultaneously vindicating and explaining it. ;Those philosophers who try to "naturalize intentionality" can be seen as seeking such proofs for intentional states. Various theories of this kind are considered: those of Fodor, Millikan, Lewis, and others. It is argued in chapters 2 and 3 that these theories are either false or unknowable. ;The case for eliminativism is examined in chapter 4, where it is argued that eliminativism is, of necessity, not a rational thesis to adopt. ;A view found in the writings of Davidson and Dennett is the topic of chapter 5. This is a kind of third-person Cartesianism: a person's mind is completely revealed by the deliverances of a suitably equipped interpreter. This position would elegantly vindicate supervenience without explaining it, at the price of a kind of anti-realism about the mind. It is argued that the price is not worth paying. ;In the sixth chapter it is argued that if the phenomenal aspects of the mind supervene, they do so mysteriously. An argument is then presented for psycho-physical supervenience. It was argued earlier that if supervenience holds for intentional states, it cannot be adequately explained. Therefore physicalism is true, but the mind-body problem has no solution. (shrink)

Phenomenal concepts are the concepts that we deploy when – but arguably not only when – we introspectively examine, focus on, or take notice of the phenomenal character of our experiences. They refer to phenomenal properties (or qualities) and they do so in a subjective (first-personal) and direct (non-relational) manner. It is through the use of such concepts that the phenomenal character of our experiences is made salient to us. Discourse about the nature of (...) class='Hi'>phenomenal concepts plays an important role in the philosophy of mind. For one, phenomenal concepts have been used to explain the epistemological relation that holds between a subject and her conscious mental states. Most prominently, however, discussions of phenomenal concepts figure in the on-going and multifaceted debate concerning the metaphysical status of consciousness. Even though some theorists have utilized phenomenal concepts in arguments purporting to show that consciousness is ontologically distinct from physical entities and processes, most accounts of phenomenal concepts are advanced having the opposite objective in mind: a proper articulation of the nature of phenomenal concepts, it is held, can defend the view that consciousness is physical against epistemic arguments to the contrary. The present entry focuses on the nature of phenomenal concepts as this is articulated and developed in attempts to defend the contention that conscious states are identical to (realized by, metaphysically necessitated by, or supervenient upon) physical states.

objects are standardly taken to be causally inert, but this claim is rarely explicitly argued for. In the context of his platonism about musical works, in order for musical works to be audible, Julian Dodd argues that abstracta are causally efficacious in virtue of their concrete tokens participating in events. I attempt to provide a principled argument for the causal inertness of abstracta by first rejecting Dodd’s arguments from events, and then extending and generalizing the causal exclusion (...) argument to the abstract/concrete distinction. For reasons of parsimony, if concrete tokens or instantiations of abstract objects account for all causal work, then there is no reason to attribute causal efficacy to abstracta, and thus reason to maintain their causal inertness. I then consider how one of the main arguments against causal exclusion, namely Stephen Yablo’s notion of “proportionality”, could be modified to support the causal efficacy of abstracta. I argue that from a few simple premises Yablo’s account in fact supports their causal inertness. Having a principled reason for the causal inertness of abstracta appears to entail that the musical platonist must admit that we never literally hear the musical work, but only its performances. I sketch a solution to this problem available to Dodd, so that the musical platonist can maintain that musical works are abstract objects and are causally inert while retaining their audibility.

We argue that any account of mental disorders that meets the desideratum of assigning causal efficacy to mental disorders faces the so-called “causal exclusion problem”. We argue that fully reductive accounts solve this problem but run into the problem of multiple realizability. Recently advocated symptom-network approaches avoid the problem of multiple realizability, but they also run into the causal exclusion problem. Based on a critical analysis of these accounts, we will present our own account according to which (...) class='Hi'>mental disorders are dispositional properties that are token-identical to physical properties. More specifically, they are analyzed as dispositions to cause the specific set of symptoms. We argue that our account is not only able to account for multiple realizability without running into the causal exclusion problem, but that it also allows for the integration of very different factors into the description and explanation of mental disorders, such as neurological and neurochemical factors on the one side and social and cultural factors on the other. It thereby gives the psychiatric level of causal explanation autonomy while securing the causal efficacy of mental disorders in a causally closed physical world. (shrink)

Contrary to certain rumours, the mind-body problem is alive and well. So argues Joseph Levine in Purple Haze: The Puzzle of Consciousness . The main argument is simple enough. Considerations of causal efficacy require us to accept that subjective experiential, or 'phenomenal', properties are realized in basic non-mental, probably physical properties. But no amount of knowledge of those physical properties will allow us conclusively to deduce facts about the existence and nature of phenomenal (...) class='Hi'>properties. This failure of deducibility constitutes an explanatory problem - an explanatory gap - but does not imply the existence of immaterial mental properties. Levine introduced this notion of the explanatory gap almost two decades ago. Purple Haze allows Levine to situate the explanatory gap in a broader philosophical context. He engages with those who hold that the explanatory gap is best understood as implying anti-materialist metaphysical conclusions. But he also seeks to distance himself from contemporary naturalistic philosophical theorizing about consciousness by arguing that reductive and eliminative theories of consciousness all fail. Levine's work is best seen as an attempt to firmly establish a definite status for the mind-body problem, i.e. that the mind-body problem is a real, substantive epistemological problem but emphatically not a metaphysical one. Because Levine's work is tightly focused upon contemporary Anglophone analytic philosophy of mind, there is little discussion of the broader conceptual background to the mind-body problem. My aim here is to place Levine's work in a broader conceptual context. In particular, I focus on the relationship between consciousness and intentionality in the belief that doing so will allow us better to understand and evaluate Levine's arguments and their place in contemporary theorizing about mentality and consciousness.

My dissertation puts forward a critique of the phenomenal intentionality theory (PIT). According to standard accounts of PIT, all genuine intentionality is either identical to or partly grounded in phenomenal consciousness. I argue that it is a conceptually significant mistake to construe conscious experiences in terms of token mental states that instantiate phenomenal properties. This mistake is predicated on ignoring an important difference in the temporal character—what I call the “temporal shape”—between states and properties (...) as opposed to conscious experiences. States and properties lack a temporal shape, but conscious experience has a temporal shape. Thus, in order to adequately capture our phenomenology of temporality we need a mental ontology that adequately reflects this distinction. A second aim of this dissertation is to defend a mereological account of phenomenal intentionality, which says that phenomenality and intentionality are related by being proper parts of a first-personal, subjective, mental event. On this approach, the conditions of satisfaction for a subject’s first-personal, subjective, mental event just are the conditions of satisfaction for phenomenal intentionality. I explore the theoretical grounds for a mereological account of phenomenal intentionality and conclude that it does a better job of explaining difficult cases like the problem of unconscious thought (e.g., your belief that “grass is green”). Thus, we have prima facie support for a mereological account of phenomenal intentionality exactly where competing accounts fail. (shrink)

David Rosenthal's higher-order thought theory is one of the most widely argued for of the higher-order accounts of consciousness. I argue that Rosenthal vacillates between two models of the HOT theory. First, I argue that these models employ different concepts of 'state consciousness'; the two concepts each refer to mental state tokens, but in virtue of different properties. In one model, the concept of 'state consciousness' is more consistent with how the term is typically used, both by (...) philosophers and scientists, and in commonsense usage. This model, however, also has its problems. In the second part of the paper, I develop a modified version of Rosenthal's transitivity principle, thereby avoiding some complications that stem from the original transitivity principle. I suggest that Rosenthal occasionally employs this modified model himself, and that the inconsistency identified in the first section of this paper might really reflect Rosenthal's vacillation between these two versions of the transitivity principle. I offer one explanation for how this equivocation may have occurred. These two versions would result if articulations of the transitivity principle employed the term 'mental state' inconsistently, to refer on some occasions merely to mental state types, and on others, to tokened mental states. I conclude by arguing, contrary to Rosenthal and others, that the theory is not incompatible with view that conscious states are uniquely casual efficacious. (shrink)

Throughout the 1990s, Jaegwon Kim developed a line of argument that what purport to be nonreductive forms of physicalism are ultimately untenable, since they cannot accommodate the causal efficacy of mental states. His argument has received a great deal of discussion, much of it critical. We believe that, while the argument needs some tweaking, its basic thrust is sound. In what follows, we will lay out our preferred version of the argument and highlight its essential dependence on a causal-powers (...) metaphysic, a dependence that Kim does not acknowledge in his official presentations of the argument.i We then discuss two recent physicalist strategies for preserving the causal efficacy of the mental in the face of this sort of challenge, strategies that (ostensibly) endorse a causal powers metaphysics of properties while offering distinctive accounts of the physical realization of mental properties. We argue that neither picture can be satisfactorily worked out, and that seeing why they fail strongly suggests that nonreductive physicalism and a causal powers metaphysic are not compatible, as our original argument contends. Since we also believe that robust realism concerning mental causation should not be abandoned, we take the argument of this paper to strongly motivate an account on which the mental is unrealized by and ontologically emergent from the physical. In a final section, we sketch what an ontologically emergentist account of the mental might look like. (shrink)

We defend Jaegwon Kim’s ‘causal inheritance’ principle from an objection raised by Jurgen Schröder. The objection is that the principle is inconsistent with a view about mental properties assumed by Kim, namely, that they are second-order properties. We argue that Schröder misconstrues the notion of second-order property. We distinguish three notions of second-order property and highlight their problems and virtues. Finally, we examine the consequence of Kim’s principle and discuss the issue of whether Kim’s ‘supervenience argument’ generalizes (...) to all special sciences or not. (shrink)

For some time now, Jaegwon Kim has argued that irreducible mental properties face the threat of causal inefficacy. The primary weapon he deploys to sustain this charge is the supervenience/exclusion argument. This argument, in a nutshell, states that any mental property that irreducibly supervenes on a physical property is excluded from causal efficacy because the underlying physical property takes care of all of the causal work itself. Originally intended for mental properties alone, it did not (...) take long for his critics to suggest the argument generalizes across all of the special science properties as well. Kim responds in two different ways to the generalization problem. The first response, which I call the higher-level solution, is ably dismissed by numerous critics. The second response, which I call the identity solution, has not faced comparable scrutiny. In this paper I argue that the identity solution faces numerous problems of its own. (shrink)

It has been argued that nonreductive physicalism leads to epiphenominalism about mental properties: the view that mental events cannot cause behavioral effects by virtue of their mental properties. Recently, attempts have been made to develop accounts of causal relevance for irreducible properties to show that mental properties need not be epiphenomenal. In this paper, I primarily discuss the account of Frank Jackson and Philip Pettit. I show how it can be developed (...) to meet several obvious objections and to capture our intuitive conception of degrees of causal relevance. However, I argue that the account requires large-scale miraculous coincidence for there to be causally relevant mental properties. I also argue that the same problem arises for two apparently very different accounts of causal relevance. I suggest that this result does not show that these accounts, on appropriate readings, are false. Therefore, I tentatively conclude that we have reason to believe that irreducible mental properties are causally irrelevant. Moreover, given that there is at leastprima facie evidence that mental properties can be causally relevant, my conclusion casts doubt on nonreductive physicalist theories of mental properties.

“Strong AI” is the view that it is possible for an artificial agent to be mentally indistinguishable from human agents. Because the behavioral dispositions of artificial agents are determined by underlying dispositional systems, Strong AI seems to entail human behavioral dispositions are also determined by dispositional systems. It is, however, highly intuitive that non-dispositional, phenomenal properties, such as being in pain, at least partially determine certain human behavioral dispositions, like the disposition to take a pain killer. Consequently, Strong (...) AI seems to conflict with an intuitive view of phenomenal properties’ role in determining human behavioral dispositions. My goal here is not directly to evaluate this tension, but rather to clarify how dispositionalism in the metaphysics of properties bears on it. While a tempting thought is that dispositionalism fits well with Strong AI’s thoroughly dispositional account of human behavior, I argue that this thought does not hold for dispositionalism in general. In particular, I argue that combining a version of the “powerful qualities view” with certain dispositionalist conceptions of the will leads to a version of the intuitive view of phenomenal properties that is radically incompatible with Strong AI. I argue further that this view also raises a challenge for the weaker claim that an artificial agent could be behaviorally indistinguishable from a human agent. (shrink)

My dissertation concerns the long-standing mind-body problem in a contemporary context. I investigate whether a content property of a mental state can be causally efficacious in bringing about behavior. I argue that general objections against the causal efficacy of content are not warranted. I then propose my own account of the causal efficacy of content. ;In Chapter 1, I examine the claim that the supervenience thesis renders mental causation incompatible with underlying physical causation. I argue that if (...) we understand the supervenience thesis and the concept of causation probabilistically, it turns out that the causal efficacy of the mental is compatible with that of the physical. ;In Chapter 2, I claim that given the compatibility claim established in the previous chapter, the computational theory of the mind can be understood as a causal hypothesis. I examine this hypothesis in details and Fodor's "narrow content" proposal. I argue that Fodor's proposal has a serious problem. ;In Chapter 3, I discuss individualism which implies that content is not a psychologically relevant property. I argue that individualism is in conflict with legitimate scientific practices and that there is no reason not to individuate psychological properties in terms of diachronic, causal relations. ;In Chapter 4, I investigate the screening-off argument that since content is unnecessary and redundant for the genesis of behavior, content cannot be causally efficacious. I argue that the argument is not valid. I also critically examine three accounts of the causal efficacy of content and claim that they fall short of conferring causal efficacy to content. ;In Chapter 5, I propose an account of causal efficacy which is consistent with the requirement of causal transaction via local, physical mechanism. My account is based on the notion of causal connection which is, in turn, understood as a category of token probabilistic causal significances. According to my account, content can be causally efficacious in bringing about behavior. I conclude that reasons qua reasons have causal have causal efficacy. (shrink)

In this essay I shall argue that the crucial assumptions of Kripke's argument, i.e. the collapse of the appearance/reality distinction in the case of phenomenal states and the idea of a qualitatively identical epistemic situation, imply an objective principle of identity for mental-state types. This principle, I shall argue, rather than being at odds with physicalism, is actually compatible with both the type-identity theory of the mind and Kripke's semantics and metaphysics. Finally, I shall sketch a version of (...) the type-identity theory. (shrink)

Mental states in psychology Many of our thoughts, emotions and motivations have intentional content: they are ‘about’ something. In this paper I present my VENI research project, which starts from the observation that the everyday practice of empirical psychological research is built on the idea that mental states have content. However, empirical psychology lacks a clear view on how mental content should be understood and how mental states could be causally efficacious in virtue of (...) their content. I focus on mental states that play a role in psychiatric symptomatology, and develop an interpretivist answer to these questions. I also offer some suggestions showing how an interpretivist notion of mental content could be used in empirical research on psychiatric symptoms. (shrink)

Non-reductive physicalism is the view that mental events cause other events in virtue of their mental properties and that mental properties supervene on, without being identical to, physical properties. Jaegwon Kim has presented several much-discussed arguments against this view. But the much simpler causal closure argument, which purports to establish that every mental property is identical to a physical property, has received less attention than Kim’s arguments. This paper aims to show how (...) a non-reductive physicalist should rebut the causal closure argument. A crucial premise in the argument is a principle stating that the physical world is causally closed. It states, roughly, that every physical event has a physical sufficient cause. I argue that when the principle is formulated in this way, the causal closure argument is invalid. Less frequently, the causal closure principle is formulated in terms of a difference-making conception of causation so that it states that every physical effect has a physical difference-making cause. I argue that the principle, so formulated, is false and the causal closure argument unsound. Either way the argument lacks the apodeictic force to compel acceptance of its conclusion. (shrink)

Semantic normativism, which is the view that semantic properties/concepts are some kind of normative properties/concepts, has become increasingly influential in contemporary meta-semantics. In this paper, I aim to argue that semantic normativism has difficulty accommodating the causal efficacy of semantic properties. In specific, I raise an exclusion problem for semantic normativism, inspired by the exclusion problem in the philosophy of mind. Moreover, I attempt to show that the exclusion problem for semantic normativism is peculiarly troublesome: while we (...) can solve mental-physical exclusion by adopting the so-called ‘autonomy approach’, a similar autonomy solution to semantic exclusion is implausible if semantic properties are understood as normative properties.

Relying on a range of now-familiar thought-experiments, it has seemed to many philosophers that phenomenal consciousness is beyond the scope of reductive explanation. (Phenomenal consciousness is a form of state-consciousness, which contrasts with creature-consciousness, or perceptual-consciousness. The different forms of state-consciousness include various kinds of access-consciousness, both first-order and higher-order--see Rosenthal, 1986; Block, 1995; Lycan, 1996; Carruthers, 2000. Phenomenal consciousness is the property that mental states have when it is like something to possess them, or when (...) they have subjectively-accessible feels; or as some would say, when they have qualia (see fn.1 below).) Others have thought that we can undermine the credibility of those thought-experiments by allowing that we possess purely recognitional concepts for the properties of our conscious mental states. This paper is concerned to explain, and then to meet, the challenge of showing how purely recognitional concepts are possible if there are no such things as qualia--in the strong sense of intrinsic (non-relational, non-intentional) properties of experience. It argues that an appeal to higher-order experiences is necessary to meet this challenge, and then deploys a novel form of higher-order thought theory to explain how such experiences are generated.

It is natural to think that our ordinary practices in giving explanations for our actions, for what we do, commit us to claiming that content properties are causally relevant to physical events such as the movements of our limbs and bodies, and events which these in turn cause. If you want to know why my body ambulates across the street, or why my arm went up before I set out, we suppose I have given you an answer when (...) I say that I wanted to greet a friend on the other side of the street, and thought that my arm's going up would be interpreted by him as a signal to stop for a moment. This widely held view might be disputed, but I shall not argue for it in this paper. I want to start with the view that our beliefs and desires and other propositional attitudes are causally relevant, in virtue of their modes and particular contents, to our movements, in order to investigate the consequences for analyses of thought content. For this purpose, I argue, in sec. II, for three necessary conditions on causal relevance: (a) a nomic sufficiency condition, (b) a logical independence condition, and (c) a screening-off condition. In sec. III, I apply these conditions to relational and functional theories of thought content, arguing that these theories cannot accommodate the causal relevance of content properties to our behaviour. I argue further that, on two plausible assumptions, one about the dependence of the mental on the physical, and the other about the availability in principle of causal explanations of our movements in terms of our non-relational physical properties, content properties can be causally relevant only if they are nomically type-correlated, relative to certain circumstances, with non-relational physical properties of our bodies. In sec. IV, I respond to a number of objections that might be advanced against this conclusion. (shrink)

Perceptions guide our actions and provide us with evidence of the world around us. Illusions and hallucinations can mislead us: they may prompt as to act in ways that do not mesh with the world around us and they may lead us to form false beliefs about that world. The capacity view provides an account of evidence that does justice to these two facts. It shows in virtue of what illusions and hallucinations mislead us and prompt us to act. (...) Moreover, it shows in virtue of what we are in a better epistemic position when we perceive than when we hallucination. In this paper, I develop the capacity view, that is, the view that perceptual experience has epistemic force in virtue of the epistemic and metaphysical primacy of the perceptual capacities employed in perception. By grounding the epistemic force of experience in facts about the metaphysical structure of experience, the capacity view is not only an externalist view, but moreover a naturalistic view of the epistemology of perceptual experience. So it is an externalist and naturalistic alternative to reliabilism. I discuss the repercussions of this view for the justification of beliefs and the epistemic transparency of mental states, as well as, familiar problem cases. (shrink)

Value, Reality, and Desire is an extended argument for a robust realism about value. The robust realist affirms the following distinctive theses. There are genuine claims about value which are true or false--there are facts about value. These value-facts are mind-independent - they are not reducible to desires or other mental states, or indeed to any non-mental facts of a non-evaluative kind. And these genuine, mind-independent, irreducible value-facts are causally efficacious. Values, quite literally, affect us. These are (...) not particularly fashionable theses, and taken as a whole they go somewhat against the grain of quite a lot of recent work in the metaphysics of value. Further, against the received view, Oddie argues that we can have knowledge of values by experiential acquaintance, that there are experiences of value which can be both veridical and appropriately responsive to the values themselves. Finally, these value-experiences are not the products of some exotic and implausible faculty of "intuition." Rather, they are perfectly mundane and familiar mental states - namely, desires. This view explains how values can be "intrinsically motivating," without falling foul of the widely accepted "queerness" objection. There are, of course, other objections to each of the realist's claims. In showing how and why these objections fail, Oddie introduces a wealth of interesting and original insights about issues of wider interest--including the nature of properties, reduction, supervenience, and causation. The result is a novel and interesting account which illuminates what would otherwise be deeply puzzling features of value and desire and the connections between them. (shrink)

As far as I can see, there are two basic ways of cashing out the claim that intentionality is ultimately phenomenal: an indirect one, according to which the intentional content of an experiential intentional mental state is determined by the phenomenal character that state already possesses, so that intentionality is so determined only indirectly; a direct one, which centers on the very property of intentionality itself and can further be construed in two manners: either that very property (...) is determined by the above phenomenal character, or it is a sui generis phenomenal property, thereby giving its own contribution to the overall phenomenal character of that state. Yet neither way sounds ultimately satisfying. For the indirect way may work only under the assumption that intentionality is monadic. Since the direct way explicitly endorses this assumption, the indirect way must give pride of place to it. Yet the direct way seems to be unsuccessful, in any of its forms. Thus, the phenomenal intentionality research program ought to give way to another research program concerning intentionality. (shrink)

My aim in this thesis is to explain how a non-reductionist metaphysics can accommodate the causal relevance of the psychological and of the special sciences generally. According to physicalism, all behavior is caused by brain-states; given "folk-psychology", behavior is caused by some psychological state. If psychological states are distinct from brain states, then our behavior is overdetermined and this, it is claimed, is unacceptable. I argue that this consequence is not unacceptable. I claim that our explanatory practice should guide our (...) ontological commitment. If we can offer true explanations that appeal to more than one event, then we are committed to overdetermination for the event explained. I argue that accepting overdetermination is not absurd and that we can give an adequate account of causal relevance for psychological and other supervenient properties. The result is a partial defense of both property and event pluralism. Recent work by Davidson, Fodor, Jackson, Kim, Pettit and Yablo receives explicit and critical discussion. (shrink)

Several philosophers have argued recently that semantic properties do play a causal role. 1 It is our view that none of these arguments are satisfactory. Our aim is to reveal some of the deficiencies of these arguments, and to reassess the question in our own way. In section 1, we shall explain in more detail what is involved in the pretheoretical idea of a causally efficacious property and so provide a fuller sense of the issue. In section 2 (...) we shall discuss Fodor's and Kim's arguments that the semantic properties of mental events are causally efficacious. Their tactic is to articulate sufficient conditions for the causal efficacy of a property, and then apply these conditions to the psychological properties under consideration. We shall show that both formulations are inadequate. However, each account can remedy some of the defects of the other. We shall argue that by putting the two together, and modifying this combined account in certain ways, we can arrive at something that might just pass as a general sufficient condition for causal efficacy. We believe that the question of causal efficacy of content is best approached as a question in the philosophy of science. If one wants to know whether a given species of property is efficacious, the most productive strategy is to find a science that investigates the properties and examine the role they are assigned. In keeping with this attitude we shall restrict our discussion to the notion of content deployed within cognitive science. In section 3 we examine the role of content in cognitive science and discuss whether this role suits content to the conditions on efficacy articulated in section two. Our conclusion will be conditional and hedged: on certain views of cognitive science, content will meet the sufficient condition for efficacy. If other views are correct, the question remains open.
