Explanatory Role of Content

Mental capacities for perceiving, remembering, thinking, and planning involve the processing of structured mental representations. A compositional semantics of such representations would explain how the content of any given representation is determined by the contents of its constituents and their mode of combination. While many have argued that semantic theories of mental representations would have broad value for understanding the mind, there have been few attempts to develop such theories in a systematic and empirically constrained way. This paper contributes to (...) that end by developing a semantics for a ‘fragment’ of our mental representational system: the visual system’s representations of the bounding contours of objects. At least three distinct kinds of composition are involved in such representations: ‘concatenation’, ‘feature composition’, and ‘contour composition’. I sketch the constraints on and semantics of each of these. This account has three principal payoffs. First, it models a working framework for compositionally ascribing structure and content to perceptual representations, while highlighting core kinds of evidence that bear on such ascriptions. Second, it shows how a compositional semantics of perception can be compatible with holistic, or Gestalt, phenomena, which are often taken to show that the whole percept is ‘other than the sum of its parts’. Finally, the account illuminates the format of a key type of perceptual representation, bringing out the ways in which contour representations exhibit domain-specific form of the sort that is typical of structured icons such as diagrams and maps, in contrast to typical discursive representations of logic and language.

The purpose of the paper is twofold. It first aims at clarifying and developing an important tension within enactivism concerning the relations between intentionality and content, once representationalism has been abandoned. In which sense(s) do enactivists (still) say that intentionality is contentful and not contentful? Secondly, it puts this tension in perspective with two paradigmatic ways of defining the relations between intentional states and their objects: Husserl’s theory of intentionality in the Logical Investigations, and Charles Sanders Peirce’s triadic semiotics.

A number of biologists and philosophers have noted the diversity of interpretations of evolvability in contemporary evolutionary research. Different clusters of research defined by co-citation patterns or shared methodological orientation sometimes concentrate on distinct conceptions of evolvability. We examine five different activities where the notion of evolvability plays conceptual roles in evolutionary biological investigation: setting a research agenda, characterization, explanation, prediction, and control. Our analysis of representative examples demonstrates how different conceptual roles of evolvability are quasi-independent and yet exhibit important (...) relationships across scientific activities. It also provides us with the resources to detail two distinct strategies for how evolvability can help to synthesize disparate areas of research and thereby potentially serve as a unifying concept in evolutionary biology.

Onofri [Onofri, A. 2018. ‘The Publicity of Thought.’ Philosophical Quarterly 68 (272): 521–541.] proposes an individuation criterion for thoughts that purports to satisfy both shareability (the notion that different thinkers, or a single thinker at different times, can and generally do think type-identical thoughts) and Frege's constraint (according to which two thoughts are different if it is possible for a rational subject to endorse one while rejecting the other). I argue that his proposal fails to satisfy Frege's constraint. Then I (...) propose a modification to Onofri's proposal to fix the problem. (shrink)

What are mental states? When we talk about people’s beliefs or desires, are we talking about what is happening inside their heads? If so, might cognitive science show that we are wrong? Might it turn out that mental states do not exist? Mental fictionalism offers a new approach to these longstanding questions about the mind. Its core idea is that mental states are useful fictions. When we talk about mental states, we are not formulating hypotheses about people’s inner machinery. Instead, (...) we simply talk "as if" people had certain inner states, such as beliefs or desires, in order to make sense of their behaviour. This is the first book dedicated to exploring mental fictionalism. Featuring contributions from established authors as well as up-and-coming scholars in this burgeoning field, the book reveals the exciting potential of a fictionalist approach to the mind, as well as the challenges it faces. In doing so, it offers a fresh perspective on foundational debates in the philosophy of mind, such as the nature of mental states and folk psychology, as well as hot topics in the field, such as embodied cognition and mental representation. Mental Fictionalism: Philosophical Explorations essential reading for advanced undergraduates, postgraduates and professionals alike. (shrink)

This chapter introduces several versions of mental fictionalism, along with the main lines of objection and reply. It begins by considering the debate between eliminative materialism (“eliminativism”) versus realism about mental states as conceived in “folk psychology” (i.e., beliefs, desires, intentions, etc.). Mental fictionalism offers a way to transcend the debate by allowing talk of mental states without a commitment to realism. The idea is to treat folk psychology as a “story” and three different elaborations of this are reviewed. First, (...) prefix semantics paraphrases a sentence like ‘Biden believes that Trump lost’ as ‘According to folk psychology, Biden believes that Trump lost’, whereby ontological commitment to belief is avoided. Similarly, pretense theory suggests that we do not assert ‘Biden believes that Trump lost’, but only pretend to assert it. Third, affective theory proposes that such discourse is used in a metaphorical way to understand a person’s affective and dispositional states vis-a-vis the community. The main objections concern whether folk psychology has the features of storytelling, and whether mental fictionalism ends up being self-refuting. The chapter also recaps a less discussed fictionalist view about “qualia” or phenomenal states, and closes by summarizing the papers contained in the volume. (shrink)

Epiphenomenalism denies some or all putative cases of mental causation. The view is widely taken to be absurd: if a theory can be shown to entail epiphenomenalism, many see that as a reductio of that theory. Opponents take epiphenomenalism to be absurd because they regard the view as undermining the evident agency we have in action and precluding substantial self-knowledge. In this paper, I defend epiphenomenalism against these objections, and thus against the negative dialectical role that the view plays in (...) philosophy of mind. I argue that nearly in all cases where a theory implies one kind of epiphenomenalism, it is an epiphenomenalism of a non-problematic kind, at least as far as issues about agency and self-knowledge are concerned. There is indeed a problematic version of epiphenomenalism, but that version is not relevant to the debates where its apparent absurdity is invoked. (shrink)

Perception of a property (e.g. a colour, a shape, a size) can enable thought about the property, while at the same time misleading the subject as to what the property is like. This long-overlooked claim parallels a more familiar observation concerning perception-based thought about objects, namely that perception can enable a subject to think about an object while at the same time misleading her as to what the object is like. I defend the overlooked claim, and then use it to (...) generate a challenge for a standard way of thinking about the relationship between visual experience and rational belief formation. Put informally, that view holds that just as we can mislead others by saying something false, illusory experience misleads by misrepresenting how things stand in the world. I argue that we ought to abandon this view in favour of some radical alternative account of the relationship between visual experience and rational belief formation. (shrink)

I present a paradoxical combination of desires. I show why it's paradoxical, and consider ways of responding. The paradox saddles us with an unappealing trilemma: either we reject the possibility of the case by placing surprising restrictions on what we can desire, or we deny plausibly constitutive principles linking desires to the conditions under which they are satisfied, or we revise some bit of classical logic. I argue that denying the possibility of the case is unmotivated on any reasonable way (...) of thinking about mental content, and rejecting those desire-satisfaction principles leads to revenge paradoxes. So the best response is a non-classical one, according to which certain desires are neither determinately satisfied nor determinately not satisfied. Thus, theorizing about paradoxical propositional attitudes helps constrain the space of possibilities for adequate solutions to semantic paradoxes more generally. (shrink)

If there is content that we reason on, cognitive content, it is in the head and accessible to reasoning mechanisms. This paper discusses the phenomenal theory of cognitive content, according to which cognitive contents are the contents of phenomenal consciousness. I begin by distinguishing cognitive content from the closely associated notion of narrow content. I then argue, drawing on prior work, that the phenomenal theory can plausibly account for the cognitive contents of many relatively simple mental states. My main focus (...) in this paper is the question whether the phenomenal theory can account for the apparently abstract and complex cognitive contents of "high-level" thoughts. It might seem dubious that the theory can account for such cognitive contents, because cognitive phenomenology is too scarce and too thin. However, I argue there are in fact few abstract or complex cognitive contents, so the phenomenal theory's predictions are correct. This position explains some apparently irrational behavior that is otherwise hard to explain, and it makes sense of the central role of inner speech and other forms of consciousness in reasoning.

In this paper I propose a hypothetical model of mental causation that I call semantic pruning and which could be defined as the causal influence of contents and meanings on the spatial configuration of the network of synapses of an individual. I will be guided by two central principles: 1) the causal influence of the mental occurs by virtue of external semantic constraints and consists in the selective activation of certain physical powers, 2) when the selective activation is continual, it (...) triggers a process of synaptic pruning in the neural and neuromuscular network.

On the dominant interpretation, Ockham is an externalist about mental content. This reading is founded principally on his theory of intuitive cognition. Intuitive cognition plays a foundational role in Ockham’s account of concept formation and judgment, and Ockham insists that the content of intuitive states is determined by the causal relations such states bear to their objects. The aim of this paper is to challenge the externalist interpretation by situating Ockham’s account of intuitive cognition vis-à-vis his broader account of efficient (...) causation. While there can be no doubt that intuitive states are causally individuated, I argue that, given Ockham’s broader theory of efficient causation (on which causation turns out to be an internal relation), this very fact entails that the content of such states is determined by factors internal (rather than external) to the states themselves.

This article examines one argument in favour of the position that the relational properties of mental states do not have causal powers over behaviour. This argument states that we establish that the relational properties of mental states do not have causal powers by considering cases where intrinsic properties remain the same but relational properties vary to see whether, under such circumstances, behaviour would ever vary. The individualist argues that behaviour will not vary with relational properties alone, which means that they (...) don’t have causal powers. Four replies are presented which all reject the premise that under such conditions behaviour can never be different, and each of these are refuted. The article concludes by arguing that knowing about the relational properties of mental states gives no predictive advantage over (and, in fact, is predictively worse than) knowing about the intrinsic properties of mental states plus context.

This paper centers around the notion that internal, mental representations are grounded in structural similarity, i.e., that they are so-called S-representations. We show how S-representations may be causally relevant and argue that they are distinct from mere detectors. First, using the neomechanist theory of explanation and the interventionist account of causal relevance, we provide a precise interpretation of the claim that in S-representations, structural similarity serves as a “fuel of success”, i.e., a relation that is exploitable for the representation using (...) system. Then, we discuss crucial differences between S-representations and indicators or detectors, showing that—contrary to claims made in the literature—there is an important theoretical distinction to be drawn between the two.

Unpleasant sensations possess a unique ability to make certain aversive actions seem reasonable to us. But what is it about these experiences that give them that ability? According to some recent evaluationist accounts, it is their representational content: unpleasant sensations represent a certain event as bad for one. Unfortunately evaluationism seems unable to make sense of our aversive behavior to the sensations themselves, for it appears to entail that taking a painkiller is akin to shooting the messenger, and is every (...) bit as unreasonable. In this paper I distinguish two versions of the shooting-the-messenger challenge: First, how do we account for the badness of unpleasant sensation? And second, how do we account for our access to that badness? I suggest plausible responses to the first question, but I also argue that the seriousness of the second has not been appreciated. I then propose a solution to the second: when we introspect our pains we also turn our emotional distress inwards, enabling them to represent our pains as bad. (shrink)

The subject of zombies is one of the most discussed and controversial topics of philosophy of mind. In this paper I will first examine the main argument of zombies, providing a summary of the current discussion. Then I will introduce a thought experiment, an epistemic window on a metaphysical scenario. By the thought experiment I will argue that zombies are logically impossible. Further I will discuss another recent epistemic window. Finally I will provide some other logical consideration to prove that (...) intentionality is not reducible to the cognitive functional aspects of the mind and that, moreover, the subjective recognition of semantic contents is necessary in order to consider as sensical the verbal behavior of a zombie.

Jaegwon Kim once refrained from excluding distinct mental causes of effects that depend upon the sufficient physical cause of the effect. At that time, Kim also refrained from excluding distinct mental explanations of effects that depend upon complete physical explanations of the effect. More recently, he has excluded distinct mental causes of effects that depend upon the sufficient cause of the effect, since the physical cause is individually sufficient for the effect. But there has been, to this point, no parallel (...) shift in the explanatory realm, such that distinct mental explanations of effects that depend upon complete physical explanations of the effect are excluded since the physical explanation is objectively complete. In this paper I consider, defend, and apply this update to the principle of explanatory exclusion—an update, which, in the final analysis, demonstrates a significant advantage that non-reductive physicalism has over reductive physicalism.

The central problem addressed by this thesis is how narrow content can be genuinely representational and relate to the individuation of mental representations. A second problem relates to the explanatory role of narrow content. The challenge facing the proponent of narrow content is that externalism is the standard position with regard to representation, individuation, and explanation, and it is often held that narrow content is either incoherent or explanatorily redundant. To this end, I defend a version of a two-component theory (...) of content which accepts that wide content is relatively uncontroversial but holds that narrow content has an important role to play. The thesis is divided into two main parts. In part one I focus on the problem of representation and the individuation of mental representations. In Chapter 1 I consider two of the main accounts of wide content from Putnam and Fodor and show that in each case there is a notion of narrow content that is compatible with the externalist approach to representation. In particular, I discuss versions of narrow content associated with two-dimensionalism and radical internalism, among other views, and highlight important objections to these existing accounts of narrow content. In response to these problems, I defend a pluralistic view of narrow content according to which there are two main forms of narrow representation, and contend that this account can be systematically supported by understanding the supervenience claim made by the internalist, the kinds of properties represented by mental representations, and the nature of the underlying mental representations that bear narrow content. I then show that this account of narrow content has the resources to respond to a common objection to narrow content. In support of this approach to narrow content I show in Chapter 2 that internalism is consistent with recent work on concepts, and in particular with concept pluralism – the view that concepts are comprised of a variety of conceptual structures. I argue that such conceptual structures can be coherently individuated by the narrow contents outlined in Chapter 1, giving rise to an internalist version of concept pluralism. I support the internalist construal of concept pluralism by identifying problems with externalist versions and responding to objections to narrow content. In Chapter 3 I develop an extended critique of social externalism, and accounts of perceptual psychology, both of which purport to have anti-internalist consequences for the individuation and nature of mental representations and provide a challenge to the account of narrow content and mental representations developed in Chapters 1 and 2. In part two, I defend the explanatory role of narrow content. In Chapter 4 I contend that the truth conditions of propositional attitude ascriptions may relate to the narrow contents expressed by attitude ascribing sentences. To show this, I defend a Fregean theory of attitude ascriptions and consider two objections to Fregean accounts that would block the relevant semantic role of narrow content. In addition, I show how this account provides a basis for rejecting two externalist arguments that rely on assumptions about the nature and role of attitude ascriptions. I contrast this account with existing internalist accounts, and show how it provides a response to Soames’ Perfect Earth objection. In Chapter 5 I critically assess two existing accounts of the role of narrow content in psychological explanations of behaviour, focusing on objections raised in connection with proximal causes and explanatory generality and causal relevance. In response to these objections, I develop an alternative approach which appeals to the rational role of reasons, and contend that only narrow content can provide a suitably rational explanation of behaviour. I show how this provides a response to the objections raised, and how the appeal to reasons provides a basis for rejecting Fodor’s more recent externalist account of behaviour. (shrink)

In this paper, I recommend a creature-level theory of representing. On this theory, a creature represents some entity just in case the creature adapts its behavior to that entity. Adapting is analyzed in terms of establishing new patterns of behavior. The theory of representing as adapting is contrasted with traditional causal and informational theories of mental representation. Moreover, I examine the theory in light of Putnam-Burge style externalism; I show that Putnam-Burge style externalism follows from and is explained by it. (...) I also suggest that the theory of representing as adapting easily accommodates a significant causal-explanatory role for representational content. (shrink)

In this commentary on Gerard O’Brien’s “How does mind matter? —Solving the content causation problem”, I will investigate the notion of representational content presented in the latter. With this notion, O’Brien aims at giving an explanation of how mind matters in physicalist terms. His argumentation is motivated by, and supposedly directed towards, a problem he calls the content causation problem. Regarding this, I am most interested in reconstructing how his account relates to the presuppositions that make this problem so pressing (...) in philosophical enquiry. O’Brien provides a very interesting answer to the question of “ why mental content matters ”, as motivated by the content causation problem. In particular, I will try to show that by making use of the notion of dispositions, it provides an interesting way of avoiding the presupposition that understanding content causation always requires the reduction of individual relational properties to individual intrinsic properties —probably because it is presupposed that such a reduction is impossible.

Fred Dretske’s account of mental causation, developed in Explaining Behavior and defended in numerous articles, is generally regarded as one of the most interesting and most ambitious approaches in the field. According to Dretske, meaning facts, construed historically as facts about the indicator functions of internal states, are the structuring causes of behavior. In this article, we argue that Dretske’s view is untenable: On closer examination, the real structuring causes of behavior turn out to be markedly different from Dretske’s meaning (...) facts. Our argument proceeds in three steps. First, we set forth the problem of meaning individuation: We argue that the proposal that meaning facts are structuring causes of behavior commits Dretske to a very fine-grained individuation of meanings that is deeply counterintuitive. In a second step, we show that even these finely individuated meaning facts cannot do the job that they are supposed to do, since information facts—which are constitutive of, but distinct from Dretske’s meaning facts—are better candidates for the role of structuring causes. Finally, we argue that it is not even information facts, but facts of co-instantiation which are the real structuring causes of behavior. In concluding, we briefly consider the options that are left for Dretske if our arguments succeed. (shrink)

In this review of Hutto and Myin's Radicalizing Enactivism, I question the adequacy of a non-representational theory of mind. I argue first that such a theory cannot differentiate cognition from other bodily engagements such as wrestling with an opponent. Second, I question whether the simple robots constructed by Rodney Brooks are adequate as models of multimodal organisms. Last, I argue that Hutto and Myin pay very little attention to how semantically interacting representations are needed to give an account of choice (...) and action. (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.

Premodern Buddhists are sometimes characterized as veritable "mind scientists" whose insights anticipate modern research on the brain and mind. Aiming to complicate this story, Dan Arnold confronts a significant obstacle to popular attempts at harmonizing classical Buddhist and modern scientific thought: since most Indian Buddhists held that the mental continuum is uninterrupted by death, they would have no truck with the idea that everything about the mental can be explained in terms of brain events. Nevertheless, a predominant stream of Indian (...) Buddhist thought, associated with the seventh-century thinker Dharmakirti, turns out to be vulnerable to arguments modern philosophers have leveled against physicalism. By characterizing the philosophical problems commonly faced by Dharmakirti and contemporary philosophers such as Jerry Fodor and Daniel Dennett, Arnold seeks to advance an understanding of both first-millennium Indian arguments and contemporary debates on the philosophy of mind. The issues center on what modern philosophers have called _intentionality_--the fact that the mind can be about other things. Tracing an account of intentionality through Kant, Wilfrid Sellars, and John McDowell, Arnold argues that intentionality cannot, in principle, be explained in causal terms. Elaborating some of Dharmakirti's central commitments, Arnold shows that despite his concern to refute physicalism, Dharmakirti's causal explanations of the mental mean that modern arguments from intentionality cut as much against his project as they do against physicalist philosophies of mind. This is evident in the arguments of some of Dharmakirti's contemporaneous Indian critics, whose critiques exemplify the same logic as modern arguments from intentionality. Elaborating these various strands of thought, Arnold shows that seemingly arcane arguments among first-millennium Indian thinkers can illuminate matters still very much at the heart of contemporary philosophy.

In cognitive neuroscience and in philosophy of mind, causation is a notion that is immensely important but usually not defined precisely enough to afford careful application. A widespread basic flaw is the confusion of causation with correlation. All empirical knowledge in the sciences is based on observing correlations; assigning causal relations to them or interpreting them causally always requires a theoretical background that is implicitly or (better) explicitly stated. This entails that differing theoretical approaches might lead to different interpretations of (...) correlations. In this special volume we attempt to contribute to an improved understanding of causation, in general, and its relationship to consciousness studies, specifically. (shrink)

Despite Spinoza’s reputation as a thoroughgoing critic of teleology, in recent years a number of scholars have argued convincingly that Spinoza does not wish to eliminate teleological explanations altogether. Recent interpretative debates have focused on a more recalcitrant problem: whether Spinoza has the resources to allow for the causal efficacy of representational content. In this paper I present the problem of mental causation for Spinoza and consider two recent attempts to respond to the problem on Spinoza’s behalf. While these interpretations (...) certainly shed some light on Spinoza’s account of cognitive economy, I argue that both fail to point the way out of the problem because they fail to differentiate between two forms of representation, one of which is causally efficacious, one of which is not. I close by suggesting that there is some reason to believe that Spinoza’s account of mind avoids some of the problems typically associated with mental causation. (shrink)

The project of treating knowledge as an empirical object of study has gained popularity in recent naturalistic epistemology. It is argued here that the assumption that such an object of study exists is in tension with other central elements of naturalistic philosophy. Two hypotheses are considered. In the first, “knowledge” is hypothesized to refer to mental states causally responsible for the behaviour of cognitive agents. Here, the relational character of truth creates a problem. In the second hypothesis “knowledge” is hypothesized (...) to refer to mental states causally responsible for the evolutionarily successful behaviour of cognitive agents. Here, the problem lies in the fact that evolution by natural selection is not necessarily conducive to truth. The result does not necessarily amount to eliminativism, however, since the naturalist may consistently reject the condition of truth that lies behind these problems. (shrink)

These studies examined whether having thoughts related to an event before it occurs leads people to infer that they caused the event— even when such causation might otherwise seem magical. In Study 1, people perceived that they had harmed another person via a voodoo hex. These perceptions were more likely among those who had first been induced to harbor evil thoughts about their victim. In Study 2, spectators of a peer’s basketball-shooting performance were more likely to perceive that they had (...) influenced his success if they had first generated positive visualizations consistent with that success. Observers privy to those spectators’ visualizations made similar attributions about the spectators’ influence. Finally, addi- tional studies suggested that these results occur even when the thought-about outcome is viewed as unwanted by the thinker and even in field settings where the relevant outcome is occurring as part of a live athletic competition.

Please allow me to recapitulate some territory that will be familiar to most readers. Here is how the problem of mental causation has typically been set up since shortly after the onset of non-reductive physicalism. It is now widely assumed that the realm of the physical is causally closed. This means that the probability of any event’s occurring is fully determined by physical causes, and physical causes alone. There is no space in the physical causal nexus for any non-physical event (...) to exert any influence. (shrink)

i> This paper takes a close look at the kinds of considerations we use to reach agreement in our ordinary (non-philosophical and non- theoretical) judgments about a person.

In this paper I will address the question of rationalizing mental causation which is involved in the processes of epistemic justification. The main problem concerning mental causation consists in the apparent incompatibility of the three following claims: (i) the subject's mental states (in particular his belief states) are realized by neural states of the subject's brain; (ii) the justifying character of belief transition consists in the fact that there are certain broadly logical relations between the contents of the relevant beliefs; (...) and (iii) all generations of neural states are, at bottom, governed by the purely physical laws. I try to reconciliate the physical necessity of the neural states generation with the logical rationality of the belief transition. Surprisingly enough, it will turn out that, in a sense, each thinking subject is logically perfect. However, in another sense we are exactly as fallible and irrational as our common-sense tells us.

Causal explanations of behavior must distinguish two kinds of cause. There are triggering causes, the events or conditions that come before the effect and are followed regularly by the effect, and structuring causes, events that cause a triggering cause to produce its effect. Moving the mouse is the triggering cause of cursor movement; hardware and programming conditions are the structuring causes of cursor movement. I use this distinction to show how representational facts can be structuring causes of behavior even though (...) biological events trigger the behavior. (shrink)

When we explain someone's behaviour, we do so by appealing to their mental states – their beliefs, desires, and so on. But, as Fred Dretske explains below, materialists have a hard time explaining how our mental states could have any effect on our behaviour.

Fred Dretske?s (1988) account of the causal role of intentional mental states was widely criticized for missing the target: he explained why a type of intentional state causes the type of bodily motion it does rather than some other type, when what we wanted was an account of how the intentional properties of these states play a causal role in each singular causal relation with a token bodily motion. I argue that the non-reductive metaphysics that Dretske defends for his account (...) of behavior can be extended to the case of intentional states, and that this extension provides a way to show how intentional properties can play the causal role that we wanted explained.

In everyday life we take it for granted that we have conscious control of some of our actions and that the part of us that exercises control is the conscious mind. Psychosomatic medicine also assumes that the conscious mind can affect body states, and this is supported by evidence that the use of imagery, hypnosis, biofeedback and other 'mental interventions' can be therapeutic in a variety of medical conditions. However, there is no accepted theory of mind/body interaction and this has (...) had a detrimental effect on the acceptance of mental causation in science, philosophy and in many areas of clinical practice. Biomedical accounts typically translate the effects of mind into the effects of brain functioning, for example, explaining mind/body interactions in terms of the interconnections and reciprocal control of cortical, neuroendocrine, autonomic and immune systems. While such accounts are instructive, they are implicitly reductionist, and beg the question of how conscious experiences could have bodily effects. On the other hand, non-reductionist accounts have to cope with three problems: (1) The physical world appears causally closed, which would seem to leave no room for conscious intervention. (2) One is not conscious of one's own brain/body processing, so how could there be conscious control of such processing? (3) Conscious experiences appear to come too late to causally affect the processes to which they most obviously relate. This paper suggests a way of understanding mental causation that resolves these problems. It also suggests that 'conscious mental control' needs to be partly understood in terms of the voluntary operations of the preconscious mind, and that this allows an account of biological determinism that is compatible with experienced free will.

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)

Mental causes are threatened from two directions: from below, since they would appear to be screened off by lower-order, e.g., neural states; and from within, since they would also appear to be screened off by intrinsic, e.g., syntactical states. A principle needed to parry the first threat -causes should be proportional to their effects- appears to leave us open to the second; for why should unneeded extrinsic detail be any less offensive to proportionality than excess microstructure? I say that the (...) second threat relies on a perversion of proportionality that would lay waste to all causal relations. (shrink)

(1) Harry believes that Twain is a writer. (2) Harry believes that Clemens is a writer. I say that this is Russellianism's most notorious consequence because it is so often used to argue against the view: many philosophers think that it is obvious that (1) and (2) can differ in truth value, and so they conclude that Russellianism is false. Let's call this the Substitution Objection to Russellianism.

In the ongoing debate, there are a set of mind-body theories sharing a certain physicalist assumption: whenever a genuine cause produces an effect, the causal efficacy of each of the nonphysical properties that participate in that process is determined by the instantiation of a well-defined set of physical properties. These theories would then insist that a nonphysical property could only be causally efficacious insofar as it is physically implemented. However, in what follows we will argue against the idea that fine-grained (...) mental contents could be physically implemented in the way that functional properties are. Therefore, we will examine the metaphysical conditions under which the implementing mechanism of a particular instance of a functional property may be individuated, and see how genuine beliefs and desires—insofar as they track the world—cannot meet such conditions.

The computational paradigm, which has dominated psychology and artificial intelligence since the cognitive revolution, has been a source of intense debate. Recently, several cognitive scientists have argued against this paradigm, not by objecting to computation, but rather by objecting to the notion of representation. Our analysis of these objections reveals that it is not the notion of representation per se that is causing the problem, but rather specific properties of representations as they are used in various psychological theories. Our analysis (...) suggests that all theorists accept the idea that cognitive processing involves internal information-carrying states that mediate cognitive processing. These mediating states are a superordinate category of representations. We discuss five properties that can be added to mediating states and examine their importance in various cognitive models. Finally, three methodological lessons are drawn from our analysis and discussion. (shrink)

Materialist explanations of cause and effect tend to embrace epiphenomenalism. Those who try to avoid epiphenomenalism tend to deny either the extrinsicness of meaning or the intrinsicness of causality. I argue that to deny one or the other is equally implausible. Rather, I prefer a different strategy: accept both premises, but deny that epiphenomenalism is necessarily the conclusion. This strategy is available because the premises do not imply the conclusion without the help of an additional premise—namely, that behavior explained by (...) reasons is caused by the reasons that explain it—and this premise is false.
