Causal theories of mental content attempt to explain how thoughts can be about things. They attempt to explain how one can think about, for example, dogs. These theories begin with the idea that there are mental representations and that thoughts are meaningful in virtue of a causal connection between a mental representation and some part of the world that is represented. In other words, the point of departure for these theories is that thoughts of (...) dogs are about dogs because dogs cause the mental representations of dogs. (shrink)

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)

Some mental states are about themselves. Nothing is a cause of itself. So some mental states are not about their causes; they are about things distinct from their causes. If this argument is sound, it spells trouble for causal theories of mental content—the precise sort of trouble depending on the precise sort of causal theory. This paper shows that the argument is sound (§§1-3), and then spells out the trouble (§4).

The project of explaining intentional phenomena in terms of nonintentional phenomena has become a central task in the philosophy of mind.' Since intentional phenomena like believing, desiring, intending have content essentially, the project is one of showing how semantic properties like content can be reconciled with nonsemantic properties like cause. As Jerry A. Fodor put it, The worry about representation is above all that the semantic (and/or the intentional) will prove permanently recalcitrant to integration in the natural order; (...) for example that the semantic/intentional properties of things will fail to supervene upon their physical properties.2.

Recently some arguments against Cartesian-style skepticism have been based on causal theories of content. I hope to show that the relevance of causal theories of content to what we can know is conditional in a more complex way than has been recognized so far.

Recently some arguments against Cartesian-style skepticism have been based on causal theories of content. I hope to show that the relevance of causal theories of content to what we can know is conditional in a more complex way than has been recognized so far.

This paper has two interrelated aims. The primary aim is to specify the character of philosophical theories of mental content that are usually classified as ‘Causal Theories of Intentionality’, ‘Causal Theories of Representation’, or ‘Causal Theories of Mental Content’ (CTs). More specifically, the aim is to characterize the role and place of causation in philosophical reflections on the nature of mental content, as suggested by theories of this kind. Elucidation (...) of the role of the concept of causation in CTs requires examining the philosophical background against which versions of CTs are proposed; therefore the second aim of this paper is to clarify the link between CTs and the two philosophical theories that accompany it: the doctrine of philosophical naturalism (PN) and the representational theory of mind (RTM). Clarification of the relationship between the three theories is not only necessary for an adequate specification of the causal component that plays a central role in CTs, and so for a better understanding of CTs themselves; it also shows how the role that causation plays in CTs implies a genuinely relational conception of intentionality.

It is generally agreed upon that Grice's causal theory of perception describes a necessary condition for perception. It does not describe sufficient conditions, however, since there are entities in causal chains that we do not perceive and not all causal chains yield perceptions. One strategy for overcoming these problems is that of strengthening the notion of causality. Another is that of specifying the criteria according to which perceptual experiences should match the way the world is. Finally, one (...) can also try to provide sufficient conditions by elaborating on the content of perceptual experiences. These different strategies are considered in this paper, with the conclusion that none of them is successful. However, a careful examination of their problems points towards the general solution that we outline at the end. (shrink)

Radical enactivism, an increasingly influential approach to cognition in general, has recently been applied to memory in particular, with Hutto and Peeters New directions in the philosophy of memory, Routledge, New York, 2018) providing the first systematic discussion of the implications of the approach for mainstream philosophical theories of memory. Hutto and Peeters argue that radical enactivism, which entails a conception of memory traces as contentless, is fundamentally at odds with current causal and postcausal theories, which remain (...) committed to a conception of traces as contentful: on their view, if radical enactivism is right, then the relevant theories are wrong. Partisans of the theories in question might respond to Hutto and Peeters’ argument in two ways. First, they might challenge radical enactivism itself. Second, they might challenge the conditional claim that, if radical enactivism is right, then their theories are wrong. In this paper, we develop the latter response, arguing that, appearances to the contrary notwithstanding, radical enactivism in fact aligns neatly with an emerging tendency in the philosophy of memory: radical enactivists and causal and postcausal theorists of memory have begun to converge, for distinct but compatible reasons, on a contentless conception of memory traces.

Causal theories of action are attempts to develop an account of actions in terms of events which have the right kind of causal ancestry. The causal ancestry must be traced back to some kind of intentional state in the agent, such intentional state must have the right kind of content, and it must cause the bodily movement in the ‘right’ way. Causal accounts differ on the nature of the intentional state, the nature of the (...) content it must have, and the specification of the ‘right’ kind of causal connection to bodily movements or other effects. Causal accounts also differ on the identification of the action itself. Some acounts say that the action is the bodily movement, provided that it was caused in the right way and had the right kind of effects. Others identify the action with the triggering intentional state, provided that it has the right kind of effects. Yet others identify the action with the composite event of the intentional state's causing the appropriate effects. Finally there are those which fail to identify the action with any of these events or combinations of them. (shrink)

Many philosophers worry that the classical computational theory of mind (CTM) engenders epiphenomenalism. Building on Block’s (1990) discussion, I formulate a particularly troubling version of this worry. I then present a novel solution to CTM’s epiphenomenalist conundrum. I develop my solution within an interventionist theory of causal relevance. My solution departs substantially from orthodox versions of CTM. In particular, I reject the widespread picture of digital computation as formal syntactic manipulation.1.

Putnam originally developed his causal theory of meaning in order to support scientific realism and reject the notion of incommensurability. Later he gave up this position and adopted instead what he called ‘internal realism’, but apparently without changing his mind on topics related to his former philosophy of language. The question must arise whether internal realism, which actually is a species of antirealism, is compatible with the causal theory of meaning. In giving an answer I begin with an (...) analysis of the content and metaphysical background of scientific realism. I show that it presupposes metaphysical realism and that Putnam's philosophical conversion is due to his becoming aware of the latter's incoherence. After giving a brief sketch of internal realism I conclude by arguing that within this new theoretical framework the causal theory of meaning loses its force as a weapon against incommensurability.

In this paper, I focus on a problem related to teleological theories of content namely, which notion of function makes content causally relevant? It has been claimed that some functional accounts of content make it causally irrelevant, or epiphenomenal; in which case, such notions of function could no longer act as the pillar of naturalized semantics. By looking closer at biological questions about behavior, I argue that past discussion has been oriented towards an ill-posed question. What (...) I defend is a Very Boring Hypothesis: depending on the representational phenomenon and the explanatory question, different aspects might be important, and it is difficult to say a priori which ones these might be. There are multiple facets to biological functionality and causality relevant for explaining representational phenomena, and ignoring them will lead to unmotivated simplifications. In addition, accounting for different facets of functionality helps dispense with intuition-based specifications of cognitive phenomena. (shrink)

According to the anti-Humean theory of motivation, it is possible to be motivated to act by reason alone. According to the Humean theory of motivation, this is impossible. The debate between these two theories remains as vigorous as ever (see for example Pettit 1987, Lewis 1988, Price 1989 and Smith 1994). In this paper I shall argue that the anti-Humean theory of motivation is incompatible with a number of prominent recent theories of content. I shall focus on (...) causal or informational theories of content (such as Dretske 1981, Fodor 1990 and Stalnaker 1984), and on verificationist theories of content (such as Dummett 1993, Putnam 1983 and Wright 1986), though in fact I believe that the same argument applies to several other theories of content as well.

The disjunction problem and the distality problem each presents a challenge that any theory of mental content must address. Here we consider their bearing on purely probabilistic causal theories. In addition to considering these problems separately, we consider a third challenge—that a theory must solve both. We call this “the hard problem.” We consider 8 basic ppc theories along with 240 hybrids of them, and show that some can handle the disjunction problem and some can handle (...) the distality problem, but none can handle the hard problem. This is our main result. We then discuss three possible responses to that result, and argue that though the first two fail, the third has some promise. (shrink)

This entry surveys a range of proposed solutions to the problem of intentionality, that is, the problem of explaining how human thoughts can be about, or be directed toward, objects. The family of solutions described here takes the content of a mental representation—what that concept represents or is about—to be a function of causal relations between mental representations and their typically external objects. This emphasis on causal relations should be understood broadly, however, so as to cover (...) class='Hi'>theories couched in terms of law-like natural relations or the law-governed way in which one natural event carries information about another.

A naturalistic scheme of primitive conceptual representations is proposed using the statistical measure of mutual information. It is argued that a concept represents, not the class of objects that caused its tokening, but the class of objects that is most likely to have caused it (had it been tokened), as specified by the statistical measure of mutual information. This solves the problem of misrepresentation which plagues causal accounts, by taking the representation relation to be determined via ordinal relationships between (...) conditional probabilities. The scheme can deal with statistical biases and does not rely on arbitrary criteria. Implications for the theory of meaning and semantic content are addressed. (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 his recent book, The Elm and the Expert, Fodor attempts to reconcile the computational model of human cognition with information‐theoretic semantics, the view that semantic, and mental, content consists of nothing more than causal or nomic relationships, between words and the world, or (roughly) brain states and the world. In this paper, we do not challenge the project. Nor do we show that Fodor has failed to carry it out. instead, we urge that his analysis, when made (...) explicit, turns out rather differently than he thinks. In particular, in some places where he sees problems, he sometimes shows that there is no problem. And while he says two conceptions of information come to much the same thing, his analysis shows that they are very different. This is rather strange. (shrink)

Externalism is the view that the intentional content of a mental state supervenes on its relations to objects in the extramental world. Nativism is the view that some of the innate states of the mind/brain have intentional content. I consider both “causal” and “nomic” versions of externalism, and argue that both are incompatible with nativism. I consider likely candidates for a compatibilist position – a nativism of “narrow” representational states, and a nativism of the contentless formal “vehicles” (...) of representational states. I argue that “narrow nativism” is either too implausible to appeal to the nativist – because it entails that innate representational states are lost as the mind becomes more experienced, or too costly to appeal to the externalist – because a reasonable version of it requires the analytic-synthetic distinction. Finally, I argue that “syntactic nativism” is indistinguishable from classical anti-nativist empiricism, given the latter’s broad tolerance for innate implementation of psychological principles and mechanisms.

Philosophical accounts of "action" standardly take an action to be a doing which _satisfies some description that is semantically related to the content of a propositional attitude of the subject's which _explains why that doing occurred. Causal theories of action require that the explanation in question must involve the causation of action-doings by propositional attitudes (typically intentions, volitions, or combinations of belief and desire). I argue that there are actions whose status, as such, cannot be acknowledged by (...) any causal theory, since no such theory can allow that they fulfill the satisfaction condition. (shrink)

The present dissertation deals with the issue of the individuation of beliefs. This is an issue that falls into philosophy of psychology as well as philosophy of language. There are two major schools of thought that are involved in the debate. Individualism claims that the individuation does not need to take intentional, semantic properties of beliefs into account, while Anti-Individualism claims that it does. The former is represented by Jerry Fodor and the latter is represented by Tyler Burge. ;This dissertation (...) is divided into three parts. In Part I, I review Tyler Burge's several attempts to refute Individualism. My conclusion is that Burge does not give us a viable alternative theory of content. In Part II, I examine Jerry Fodor's arguments for a new form of Individualism, one that proposes to individuate beliefs with respect to their causal powers. My conclusion is that Fodor runs into a problem in arguing that the individuation of mental states should be based on causal powers alone, since he would have to sacrifice the causal relevance of intentional mental properties. Finally in Part III, I formulate my arguments against Fodor's Individualism. I first present a holistic view of beliefs according to which, beliefs cannot be considered in isolation from the individual's system of beliefs. My view is that the individuation of beliefs not only needs to consider the semantic properties of the belief in question, it also needs to consider the semantic properties of relevant beliefs. I then argue for the causal relevance of intentional mental properties. My conclusion is that since the individuation of beliefs has to be based on groupings of their intentional, semantic properties, Individualism cannot be accepted. (shrink)

An argument is offered against three naturalistic theories of intentional content: causal-covariation theories, teleological theories, and certain versions of conceptual role semantics. The strategy involves focusing on a normative problem regarding the practice of associating content expressions (e.g., that-clauses) with internal entities (states, symbol structures, etc.). The problem can be expressed thus: Which content expressions are the right ones to associate with internal entities? I argue, first, that an empirical solution to this problem—what (...) I call the Normative Problem—will follow naturally from a descriptive-explanatory account of the practice of associating content expressions with internal entities; and second, that the empirical solution will be accepted and adopted within cognitive science. Naturalistic theories of content also entail solutions to the Normative Problem, and such theories are shown to be false by showing that their solutions to the Normative Problem are inconsistent with the empirical solution coming out of cognitive science. (shrink)

Some proponents of structural representations (henceforth, structuralists) claim that no other theory of representation can legitimatize the explanatory appeals that cognitive science makes to mental content. Because other naturalistic approaches to representation purportedly posit an arbitrary relation between representing vehicles and representational content, these approaches must appeal to the role played by a representation, i.e., how it is used by the system in which it is embedded, to ground its content. This is in supposed contrast to structural (...) representations, in which the relation of resemblance results in a non-arbitrary relationship between vehicles and content. Structuralists argue that, as a result, approaches that posit structural representations can, and alternative approaches cannot, explain how representational content can be causally relevant in the production of behavior. In this paper, I will argue that structural representations are susceptible to the very same critiques that proponents level against what they sometimes refer to as “use” theories. This, I contend, is not surprising given that a theory of structural representations is, in fact, just as much a use-theory as alternative approaches. (shrink)

Jerry Fodor has recently proposed a new entry into the list of information based approaches to semantic content aimed at explicating the general notion of representation for both mental states and linguistic tokens. The basic idea is that a token means what causes its production. The burden of the theory is to select the proper cause from the sea of causal influences which aid in generating any token while at the same time avoiding the absurdity of everything's being (...) literally meaningful (since everything has a cause). I argue that a detailed examination of the theory reveals that neither burden can be successfully shouldered. (shrink)

We start this paper by arguing that causality should, in analogy with force in Newtonian physics, be understood as a theoretical concept that is not explicated by a single definition, but by the axioms of a theory. Such an understanding of causality implicitly underlies the well-known theory of causal nets and has been explicitly promoted by Glymour. In this paper we investigate the explanatory warrant and empirical content of TCN. We sketch how the assumption of directed cause–effect relations (...) can be philosophically justified by an inference to the best explanation. We then ask whether the explanations provided by TCN are merely post-facto or have independently testable empirical content. To answer this question we develop a fine-grained axiomatization of TCN, including a distinction of different kinds of faithfulness. A number of theorems show that although the core axioms of TCN are empirically empty, extended versions of TCN have successively increasing empirical content. (shrink)

This is a paper about The Causal Self-Referential Theory of Perception. According to The Causal Self-Referential Theory as developed by above all John Searle and David Woodruff Smith, perceptual content is satisfied by an object only if the object in question has caused the perceptual experience. I argue initially that Searle's account cannot explain the distinction between hallucination and illusion since it requires that the state of affairs that is presented in the perceptual experience must exist in (...) order for the perception to be veridical. Smith's account is interestingly different in that the descriptive content, i.e. the content that presents the perceptual object as having certain properties, does not determine the object of the experience. His account consequently does not require that the state of affairs that is presented in perception exists in order for the perception to have an object. Smith argues instead that perceptual reference is determined by a specific kind of demonstrative content. In this paper it is argued that Smith's account of demonstrative content is too indeterminate and in certain circumstances prescribes the wrong object. It is subsequently argued that the theory of demonstrative content can be modified so as to avoid these consequences. This modification involves deriving the conditions of satisfaction of seeing an object from the conditions of satisfaction of seeing the shape of the object, where the shape of the object is conceived of as a particularized property, what is also called a ‘trope’.

In her landmark book, Language, Thought, and Other Biological Categories (Millikan1984),1 Ruth Garrett Millikan utilizes the idea of a biological function to solve philosophical problems associated with the phenomena of language, thought, and meaning. Language and thought are activities of biological organisms, according to Millikan, and we should treat them as such when trying to answer related philosophical questions. Of special interest is Millikan’s treatment of intentionality. Here Millikan employs the notion of a biological function to explain what it is (...) for one thing in nature, a bee dance (43), for example, to be about another, in this case, the location of a nectar source. My concern in this paper is to understand whether Millikan’s account of intentionality adequately explains how humans achieve reference, in language or thought, to individuals and groups in their environment. In bringing her theory of intentional content to bear on human activities, Millikan focuses largely on natural language. Thus, in what follows, I begin by laying out the biology-based principles that underlie Millikan’s theory of content, then proceed with an explanation of how the theory is to apply to natural language. As it appears, Millikan’s account of how content is determined for natural language terms and sentences rests on the determinacy of intentional content at the psychological level. This leads me to take a careful look at what Millikan says about the content of mental representations, in hopes of finding a sufficient basis there for the application of Millikan’s theory of content to natural language. Ultimately, I conclude that Millikan’s theory faces a problem of vacuity. If we approach the theory as a theory of intentional content, intended to explain the nature of reference, the theory is lacking in an extremely important respect: Millikan explains how it could be one of the biological functions of a mental or natural language term to refer, without telling us precisely what in the natural order constitutes the reference relation..

This provocative but persuasive book is essentially a radical attack upon the Humean conception of causality and the presentation and defense of a counter-theory, closer to everyday experience and pre-Humean traditional views. As formulated by empiricist philosophers, the Humean approach depends on two basic postulates. The philosophical analysis of any non-empirical concept must be a formal explication; any residue elements have to be accounted for in terms of their psychological origins. The world as experienced can be conceived adequately as a (...) logically independent system of things or flux of events, without the unwarranted assumption that individuals persist diachronically. As the grounds for undermining these assumptions, the authors develop a conception of causes as "powerful particulars," i.e., things which have both a nature and powers. So long as the nature remains unchanged the agent in question will continue to behave in this fashion with a natural necessity, stemming from the individual’s nature and specific powers. The opening chapter discusses the problem of conceptual and natural necessity—as distinct from logical necessity which alone is allowed by the Humean empiricists. Natural necessity is the mark of the relationship between real causes and their respective effects, whereas conceptual necessity characterizes the way our statements about such are themselves related. Later the irreducibility of natural necessity is emphasized and its differences from logical entailment spelled out. Chapter two takes up the subject of the "regularity theory and its allies." Characteristic of such are two claims: the empirical content of a causal-relationship statement is exhausted by the actual or hypothetical regularity between independent entities, and the necessity ordinarily attributed to causal production is an illusion, to be accounted for in various ways. Subsequent chapters are devoted to assaulting the pillars of the Humean notion either directly or indirectly through an illuminating and attractive account of their own theory of nature, causal powers, and natural necessity. The final chapter, entitled "Fields of Potential," indulges in speculation about the nature of ultimate entities on the basis of an extended generalization of the notion of the powerful individual, and concludes with a brief account of the historical antecedents of Faraday’s modern field theory and the metaphysical implications of a generalized field theory.—A.B.W.

The thesis of this paper is that the causal theory of mental content (hereafter CT) is incompatible with an elementary fact of perceptual psychology, namely, that the detection of distal properties generally requires the mediation of a “theory.” I shall call this fact the nontransducibility of distal properties (hereafter NTDP). The argument proceeds in two stages. The burden of stage one is that, taken together, CT and the language of thought hypothesis (hereafter LOT) are incompatible with NTDP. The (...) burden of stage two is that acceptance of CT requires acceptance of LOT as well. It follows that CT is incompatible with NTDP. I organize things in this way in part because it makes the argument easier to understand, and in part because the stage-two thesis—that CT entails LOT—has some independent interest and is therefore worth separating from the rest of the argument.

This paper is an attempt to present a Kripkean (Causal) picture of Reference where the cognitive content in fixing reference plays a vital role. It also points out that Kripke is not a pure causal theorist. By introducing Thomas Kuhn and his theory on vulnerability of the rigid designation, I have shown that there is a danger for causal theory of reference. However Kuhn’s argument fails to have an impact if a Knowledge aspect is augmented to (...) Kripkean theory of reference. This new causal theory of reference preserves the truth of the referential term in spite of the vulnerability of the rigid designation and problem of reference change. It can also adequately answer the question of theoretical terms reference failure. (shrink)

The current essay introduces the guidance theory of representation, according to which the content and intentionality of representations can be accounted for in terms of the way they provide guidance for action. The guidance theory offers a way of fixing representational content that gives the causal and evolutionary history of the subject only an indirect role, and an account of representational error, based on failure of action, that does not rely on any such notions as proper functions, (...) ideal conditions, or normal circumstances. Moreover, because the notion of error is defined in terms of failure of action, the guidance theory meets the “meta-epistemological requirement” that representational error should be potentially detectable by the representing system itself. In this essay, we offer a brief account of the biological origins of representation, a formal characterization of the guidance theory, some examples of its use, and show how the guidance theory handles some traditional problem cases for representation: the representation of fictional and abstract entities. Being both representational and actiongrounded, the guidance theory may provide some common ground between embodied and cognitivist approaches to the study of the mind. (shrink)

HOW NOT TO REFUTE HUME'S THEORY OF CAUSALITY: A REPLY TO GRAY Mr. Robert Gray's alleged refutation of Hume's theory of causality does not strike me as being in reality conclusive. The essential element in his alleged refutation, if I have understood it correctly, is that when two billiard balls strike one another and stop - a paradigm of cause and effect - the striking and the (...) stopping constitute one event as opposed to two. They occupy, as a result, one and the same time, a state of affairs inconsistent with the Humean view that the cause immediately precedes the effect. But, surely, they would, if they are the same event, occupy by parity of reasoning one and the same position. For Hume's theory of space and time, as Gray describes it, implies that there is a one-to-one mapping between positions and times. If, therefore, their being the same event implies that they occupy one and the same time, it would also imply that they occupy one and the same position. And if they occupy the same position, they are not spatially contiguous, a state of affairs inconsistent with the Humean view that the cause is spatially contiguous to the effect. A Humean solution in both cases seems clear. It is to allow that the striking and stopping of the billiard balls are the same event and to seek its cause in their moving towards one another, i.e. to seek it in billiard ball A's being at A, and billiard ball B's being at B,, where both A, and B, are spatially contiguous with and immediately precede the striking and stopping of the respective billiard balls B and A. Gray resists this solution, but only because he is implicitly committed to the anti-Humean view that one and the same event can occupy two different positions at one and the same time. As a result, where A designates the 52. position where billiard ball A strikes billiard ball B and stops it and B designates the position where billiard ball B strikes billiard ball A and stops it - this being simply a re-descriptiön in Gray's view of what happens in the single event of two billiard balls striking one another and stopping - he holds that A is different from B. If A is different from B, then by relocating the cause of billiard ball A's stopping at B, we have sacrificed the spatial contiguity of cause and effect. For B will intervene between position B,, that of the cause, and A, that of the effect. And the same will hold with obvious adjustments when we relocate the cause of billiard ball B's stopping at A,. Fortunately, however, Hume need only reply that A is one and the same as B. Indeed, if he is to be consistent with his theory of space and time, this must be his reply. This reply, moreover, is necessary to Hume's explanation of how the reciprocal striking of billiard ball A and billiard ball B can exist in the first place. Such a phenomenon requires a point of contact, a point common to a part of both billiard balls. This point of contact, it should be clear, is provided by the point designated by both A and B.

If, therefore, their being the same event implies that they occupy one and the same time, it would also imply that they occupy one and the same position. And if they occupy the same position, they are not spatially contiguous, a state of affairs inconsistent with the Humean view that the cause is spatially contiguous to the effect. A Humean solution in both cases seems clear. It is to allow that the striking and stopping of the billiard balls are the same event and to seek its cause in their moving towards one another, i.e. to seek it in billiard ball A's being at A, and billiard ball B's being at B,, where both A, and B, are spatially contiguous with and immediately precede the striking and stopping of the respective billiard balls B and A. Gray resists this solution, but only because he is implicitly committed to the anti-Humean view that one and the same event can occupy two different positions at one and the same time. As a result, where A designates the 52. position where billiard ball A strikes billiard ball B and stops it and B designates the position where billiard ball B strikes billiard ball A and stops it - this being simply a re-descriptiön in Gray's view of what happens in the single event of two billiard balls striking one another and stopping - he holds that A is different from B. If A is different from B, then by relocating the cause of billiard ball A's stopping at B, we have sacrificed the spatial contiguity of cause and effect. For B will intervene between position B,, that of the cause, and A, that of the effect. And the same will hold with obvious adjustments when we relocate the cause of billiard ball B's stopping at A,. Fortunately, however, Hume need only reply that A is one and the same as B. Indeed, if he is to be consistent with his theory of space and time, this must be his reply. This reply, moreover, is necessary to Hume's explanation of how the reciprocal striking of billiard ball A and billiard ball B can exist in the first place. Such a phenomenon requires a point of contact, a point common to a part of both billiard balls. This point of contact, it should be clear, is provided by the point designated by both A and B.

In order to resolve the controversial discussion regarding content effects in deductive reasoning, we propose distinguishing between two inferential sources—an argument's form , and additional relations people associate with the argument's content —and analysing their interplay. Both sources are equally necessary in order to understand the role content plays in deductive reasoning. People make valid deductions from the content relations ( content competence ), but in thematic reasoning tasks, these deductions lead to the intriguing phenomenon (...) known as content effects . Focusing on the interplay of both sources of inferences, the dual source distinction enables a novel class of predictions to be made, namely the correct mastery of the logical connectors ( form competence ) in tasks that require the individual to think about an argument's form in relation to its content. To illustrate the dual source approach and its implications, the selection task paradigm of conditional reasoning with a point of view is used in combination with two content domains: conditional promises with cheating and non-cheating perspectives and technical systems with causal perspectives. Experimental findings corroborate all three phenomena: content competence, content effects, and form competence. The dual source distinction is discussed with regard to current theories of reasoning.

In lieu of an abstract, here is a brief excerpt of the content:76. A REFUTATION OF HUME'S THEORY OF CAUSALITY1 Given Hume's conceptions of space and time, which I take to be fundamental to his theory of causality, it is not always possible to meet all of those conditions definitive of the cause-effect relation, i.e., those "general rules, by which we may know when" objects really 2 are "causes or effects to each other" (T. 173). To show this, it (...) will be necessary, first, to give a very brief exposition of Hume's conceptions of space and time, with regard chiefly to their implications for the nature of motion. Then, after briefly summarizing his views on the nature of the cause-effect relation, I shall proceed immediately to my objection. It should be noted first, however, that, if one instance of a cause-effect relation can be found to which Hume's analysis will not apply, that, presumably, would be sufficient to refute his theory. I shall not here repeat all of Hume's arguments for the indivisibility of space and time. Suffice it to say, he takes it to be fairly obvious that each must consist of a finite number of indivisible points or moments, each of which is distinct, and therefore separate, from every other, and, in the case of time, none of which ever "co-exist." Only one of his arguments for the indivisibility of space need concern us here. The argument is brief: The infinite divisibility of space implies that of time, as is evident from the nature of motion. If the latter, therefore, be impossible, the former must be equally so. (T. 31) The argument here seems, roughly, to be this: the motion of an object can be described only by giving its positions at various times (the nature of motion). If, therefore, an object, such as a ball moving along a line AB, can be assigned an infinite number of positions taken between A and B (the infinite divisibility of space), 77. the time taken to traverse AB must also be infinite, i.e., must consist of an infinite number of instants. But the finite time taken to traverse the distance AB is not infinitely divisible; therefore, neither is the line AB. This argument, of course, relies upon the assumption that, in traversing the line AB, the ball will occupy each of the points (whether finite or infinite) of which it consists. The argument can also be turned around so as to derive the finite divisibility of time from that of space. Here, too, it must be assumed that the ball occupies each of those instants which constitute the time taken to traverse the line AB. It thus seems clear that, on Hume's view, the ball's motion can be neither more nor less divisible than the space and time it takes to move. x In its motion from A to B, then, the ball will occupy first one, then another of the points lying between A and B until finally it has occupied them all and has moved from A to B. But, in saying that it will occupy first one and then another, we are saying nothing more than that it successively occupies a series of points, and, insofar as its occupation of these different points is successive, it takes time. We are in a position, then, to define motion (at least motion along a straight line) as "the successive occupation of adjacent, linearly ordered points or places." Now, this is very different from the usual conception of motion. The ball's motion between any two adjacent points is not a moving from one to the other. It is simply its being in the one place at one instant and its being in the other place at the next. It is not a continuous motion, but the occupation of discrete places at different times. It is, as it were, a series of instantaneous leaps. This interpretation, if it is accurate, may also serve to account for Hume's ill-understood propensity for 78. referring to cause and effect as objects rather than as events. Events must, on Hume's view of time at least, be essentially static. Unlike those... (shrink)

Contemporary philosophy and theoretical psychology are dominated by an acceptance of content-externalism: the view that the contents of one's mental states are constitutively, as opposed to causally, dependent on facts about the external world. In the present work, it is shown that content-externalism involves a failure to distinguish between semantics and pre-semantics---between, on the one hand, the literal meanings of expressions and, on the other hand, the information that one must exploit in order to ascertain their literal meanings. (...) It is further shown that, given the falsity of content-externalism, the falsity of the Computational Theory of Mind (CTM) follows. It is also shown that CTM involves a misunderstanding of terms such as "computation," "syntax," "algorithm," and "formal truth." Novel analyses of the concepts expressed by these terms are put forth. These analyses yield clear, intuition-friendly, and extensionally correct answers to the questions "what are propositions?, "what is it for a proposition to be true?", and "what are the logical and psychological differences between conceptual (propositional) and non-conceptual (non-propositional) content?" Naively taking literal meaning to be in lockstep with cognitive content, Burge, Salmon, Falvey, and other semantic externalists have wrongly taken Kripke's correct semantic views to justify drastic and otherwise contraindicated revisions of commonsense. (Salmon: What is non-existent exists; at a given time, one can rationally accept a proposition and its negation. Burge: Somebody who is having a thought may be psychologically indistinguishable from somebody who is thinking nothing. Falvey: somebody who rightly believes himself to be thinking about water is psychologically indistinguishable from somebody who wrongly thinks himself to be doing so and who, indeed, isn't thinking about anything.) Given a few truisms concerning the differences between thought-borne and sentence-borne information, the data is easily modeled without conceding any legitimacy to any one of these rationality-dismantling atrocities. (It thus turns out, ironically, that no one has done more to undermine Kripke's correct semantic points than Kripke's own followers!). (shrink)

The paper aims to show, first, that O’Regan’s and Noë’s Sensorimotor Theory of Vision and Visual Experiences suffers from circularity, and that evidence from empirical research within perception psychology unequivocally invalidates their theory. Secondly, to show that the circularity in O’Regan’s and Noë’s theory of vision and in other general causal and functional theories of perception (i.e. Gibson’s and Marr’s theories of perception) is the inevitable consequence of mutually conflicting assumption of Cartesian dualism underlying these theories. (...) The paper concludes by outlining the consequences of this conflict of assumptions for psychological theories of perception. (shrink)

The Computational Theory of Mind (CTM) holds that the mind is a computer and that cognition is the manipulation of representations. CTM is commonly viewed as the main hypothesis in cognitive science, with classical CTM (related to the Language of Thought Hypothesis) being the most popular variant. However, other computational accounts of the mind either reject LOTH or do not subscribe to RTM. CTM proponents argue that it clarifies how thought and content are causally relevant in the physical world, (...) and they frame this argument in terms of the physical symbol hypothesis, formalism, or syntactic engines. This article focuses on specific problems with CTM, with four main sections covering the introduction of the three main variants of CTM, the most important conceptions of computational explanation in cognitive science, skeptical arguments against CTM raised by Hilary Putnam, and common objections to CTM.

This thesis is an examination and critique of naturalistic representational theories of phenomenal character. Phenomenal character refers to the distinctive quality that perceptual and sensational experiences seem to have; it is identified with 'what it is like' to undergo experiences. The central claims of representationalism are that phenomenal character is identical with the content of experience and that all representational states, bearing appropriate relations to the cognitive system, are conscious experiences. These claims are taken to explain both how (...) conscious experiential states arise and their nature. After examining the desiderata for naturalistic explanations, I argue that theories which ascribe nonconceptual content to experiences are the most plausible versions of representationalism. Further, causal covariation and teleological theories yield distinctive and interesting representationalist positions, hence, they become the focus of this study. To assess representationalism, I investigate whether all differences in phenomenal character can be correlated with differences in content. I claim that a useful distinction can be drawn between implicit and explicit content, which allows one to best describe the phenomena of perfect and relative pitch. I then argue that ambiguous figures show that two experiences can have the same content but different phenomenal character. I explicate the Inverted Earth hypothesis and claim that to identify content and phenomenal character, representationalists either have to condone the possibility of philosophical zombies, or hold that people lack authoritative first-person knowledge of their current experiences. Both these positions are unpalatable. Finally, I argue that representationalists cannot ascribe contents to experiences of novel colours to account for their phenomenal character. I also question, in light of dissociation phenomena, whether there is one distinctive relationship that all experiences bear to the cognitive system. I conclude that phenomenal character cannot be identical with the type of content under investigation, and that naturalistic representationalist theories cannot fully explain conscious experience.

The relationship between quantum collapse and consciousness is reconsidered under the assumption that quantum collapse is an objective dynamical process. We argue that the conscious observer can have a distinct role from the physical measuring device during the process of quantum collapse owing to the intrinsic nature of consciousness; the conscious observer can know whether he is in a definite state or a quantum superposition of definite states, while the physical measuring device cannot “know”. As a result, the consciousness observer (...) can distinguish the definite states and their quantum superposition, while the physical measuring device without consciousness cannot do. This provides a possible quantum physical method to distinguish man and machine. The new result also implies that consciousness has causal efficacies in the physical world when considering the existence of quantum collapse. Accordingly consciousness is not reducible or emergent, but a new fundamental property of matter. This may establish a quantum basis for panpsychism, and make it be a promising solution to the hard problem of consciousness. Furthermore, it is suggested that a unified theory of matter and consciousness includes two parts: one is the psychophysical principle or corresponding principle between conscious content and matter state, and the other is the complete quantum evolution of matter state, which includes the definite nonlinear evolution element introduced by consciousness and relating to conscious content. Lastly, some experimental schemes are presented to test the proposed quantum theory of consciousness. (shrink)
