The so-called transparency of experience (TE) is the intuition that, in introspecting one’s own experience, one is only aware of certain properties (like colors, shapes, etc.) as features of (apparently) mind-independent objects. TE is quite popular among philosophers of mind and has traditionally been used to motivate Representationalism, i.e., the view that phenomenal character is in some strong way dependent on intentionality. However, more recently, others have appealed to TE to go the opposite way and support the phenomenal intentionality view (...) (PIV), according to which intentionality is in some strong way dependent on phenomenal character. If this line of argument succeeds, then not only TE does not speak in favor of Representationalism, but it actually speaks against it, contrary to the philosophical common-sense of the last two decades. Moreover, the representationalist project of naturalizing phenomenal character turns out to be seriously undermined on the same intuitive grounds that were supposed to make it plausible. In this paper, I reconstruct and discuss the line of argument from TE to PIV and argue that our introspective intuitions (TE) do not push us in the direction of PIV. On the contrary, the line of argument from TE to PIV is (at best) simply too weak to force us to conclude that intentionality depends on phenomenal character in the sense required for PIV to be true.

Is temporal representation constitutively necessary for perception? Tyler Burge (2010) argues that it is, in part because perception requires a form of memory sufficiently sophisticated as to require temporal representation. I critically discuss Burge’s argument, maintaining that it does not succeed. I conclude by reflecting on the consequences for the origins of temporal representation.

The naturalistically inclined philosopher of mind faces two related challenges: show how mental content could be part of the natural world, and show how content can be one of the factors responsible for producing behaviour, that is, show that content is not epiphenomenal. One might pursue the first goal with the intent of showing that mental content is epiphenomenal, but it is more likely that the philosopher concerned with showing how content can be naturalized also expects content to be causally (...) efficacious. Indeed, why pursue the first challenge while holding that content is epiphenomenal? Thus these two challenges overlap: show how content can be naturalized without making content epiphenomenal.

This is not surprising, given that vision holds for us a certain prestige. Our visual experience is incredibly rich, offering up a mosaic (...) of apparent three-dimensional objects. For this reason, it is commonplace to suppose that visual experience is world-directed, with the view taking its most popular form in the representational, or content, view. World-directed views contrast with what we might call subjectivist views — views according to which experiences are raw feels or mere sensations. (shrink)

The basic assumption present in these articles is that naturalism is highly compatible with a wide range of relevant philosophical questions and that, regardless of the classical problems faced by the naturalist, the price paid in endorsing naturalism is lower than that paid by essentialist or supernaturalist theories. Yet, the reader will find a variety of approaches, from naturalism in Moral Philosophy and Epistemology to naturalism in the Philosophy of Language, Philosophy of Mind and of the Aesthetics.

Many philosophers and scientists have argued that the difference between phenomenally conscious states and other kind of states lies in the implicit self-awareness that conscious states have. Higher-Order Representationalist theories, attempt to explain such a self-awareness by means of a higher-order representation. Consciousness relies on our capacity to represent our own mental states, consciousness depends on our Theory of Mind. Such an ability can, at least conceptually, be decomposed into another two: mindreading and metacognition. In this paper I will argue (...) that consciousness cannot depend on mindreading. The tenability of HOR theories depends, therefore, on the relation between mindreading and metacognition. I analyze several views on such a relation and argue that none of them seem to be a plausible option for HOR theories. (shrink)

When the environment in which an organism lives deviates in some essential way from that to which it is adapted, this is described as “evolutionary mismatch,” or “evolutionary novelty.” The notion of mismatch plays an important role, explicitly or implicitly, in evolution-informed cognitive psychology, clinical psychology, and medicine. The evolutionary novelty of our contemporary environment is thought to have significant implications for our health and well-being. However, scientists have generally been working without a clear definition of mismatch. This paper defines (...) mismatch as deviations in the environment that render biological traits unable, or impaired in their ability, to produce their selected effects. The machinery developed by Millikan in connection with her account of proper function, and with her related teleosemantic account of representation, is used to identify four major types, and several subtypes, of evolutionary mismatch. While the taxonomy offered here does not in itself resolve any scientific debates, the hope is that it can be used to better formulate empirical hypotheses concerning the effects of mismatch. To illustrate, it is used to show that the controversial hypothesis that general intelligence evolved as an adaptation to handle evolutionary novelty can, contra some critics, be formulated in a conceptually coherent way.

The principal aim of my thesis is to provide a unified theory of imagining, that is, a theory which aspires to capture the common nature of all central forms of imagining and to distinguish them from all paradigm instances of non-imaginative phenomena. The theory which I intend to put forward is a version of what I call the Agency Account of imagining and, accordingly, treats imaginings as mental actions of a certain kind. More precisely, it maintains that imaginings are mental (...) actions that aim at the formation of episodic representations, the content of which is directly determined by what we want them to represent. My defence of this version of the Agency Account happens in two stages. On the one hand, I try to show that it is both extensionally adequate and explanatorily illuminating with respect to those mental states or projects which are clear instances of either imaginative or non- imaginative phenomena. And on the other hand, I seek to demonstrate that the most plausible alternative to the Agency Account - namely the Cognitive Account according to which it is distinctive of imaginings that they are non-cognitive phenomena and thus to be contrasted with perceptions, judgements, and so on - is bound to fail as a unified theory of imagining. The dissertation contains five main parts. In the first, I specify in more detail what a unified account of imagining has to achieve and, in particular, which phenomena it is supposed to capture. The second part presents the Cognitive Account, thereby focussing on Brian O'Shaughnessy's sophisticated version of it while the third part is reserved for the evaluation and rejection of the Cognitive Account. In the fourth part, I develop my version of the Agency Account of imagining. And the fifth and last part is concerned with the accommodation of potential counterexamples to it. (shrink)

Empirical discussions of mental representation appeal to a wide variety of representational kinds. Some of these kinds, such as the sentential representations underlying language use and the pictorial representations of visual imagery, are thoroughly familiar to philosophers. Others have received almost no philosophical attention at all. Included in this latter category are analogue magnitude representations, which enable a wide range of organisms to primitively represent spatial, temporal, numerical, and related magnitudes. This article aims to introduce analogue magnitude representations to a (...) philosophical audience by rehearsing empirical evidence for their existence and analysing their format, their content, and the computations they support. 1 Background1.1 Evidence of analogue magnitude representations1.2 Weber’s law1.3 Scepticism about analogue magnitude representations2 Format2.1 Carey’s analogy2.2 Neural realization2.3 Analogue representation2.4 Analogue magnitude representation components3 Content3.1 Do analogue magnitude representations have representational content?3.2 What do analogue magnitude representations represent?3.3 What content types do analogue magnitude representations have?4 Computations4.1 Arithmetic computation4.2 Practical deliberation5 Conclusion.

Reliable misrepresentation is getting things wrong in the same way all the time. In Mendelovici 2013, I argue that tracking theories of mental representation cannot allow for certain kinds of reliable misrepresentation, and that this is a problem for those views. Artiga 2013 defends teleosemantics from this argument. He agrees with Mendelovici 2013 that teleosemantics cannot account for clean cases of reliable misrepresentation, but argues that this is not a problem for the views. This paper clarifies and improves the argument (...) in Mendelovici 2013 and response to Artiga's arguments. Tracking theories, teleosemantics included, really do need to allow for clean cases of reliable misrepresentation. (shrink)

Speakers are confused about identity if they mistake one thing for two or two things for one. I present two plausible models of confusion, the Frege model and the Millikan model. I show how a prominent objection to Fregean models fails and argue that confusion consists in having false implicit beliefs involving the identity relation. Further, I argue that confused identity has characteristic corruptive effects on singular cognition and on the proper function of singular terms in linguistic communication.

In this paper I assess the explanatory role of internal representations in connectionist models of cognition. Focusing on both the internal‘hidden’units and the connection weights between units, I argue that the standard reasons for viewing these components as representations are inadequate to bestow an explanatorily useful notion of representation. Hence, nothing would be lost from connectionist accounts of cognitive processes if we were to stop viewing the weights and hidden units as internal representations.

In ‘Of Sensory Systems and the “Aboutness” of Mental States’, Kathleen Akins (1996) argues against what she calls ‘the traditional view’ about sensory systems, according to which they are detectors of features in the environment outside the organism. As an antidote, she considers the case of thermoreception, a system whose sensors send signals about how things stand with themselves and their immediate dermal surround (a ‘narcissistic’ sensory system); and she closes by suggesting that the signals from many sensory systems may (...) not in any familiar sense be about anything at all. Her presentation of the issues, however, overlooks resources available to ‘the traditional view’—or so I shall argue. Akins’s own thumbnail sketch of what is wrong with the traditional view is that it asks, concerning a given sensory system, ‘what is it detecting?’, when we should instead be asking ‘what is it doing?’ (352). Her point is that on the traditional view the function of a sensory system—what it's ‘for’—is to detect or indicate (values of) features of the outside environment. But at least on one version of the traditional view—namely Ruth Millikan’s—this would never be the sole or main proper function of a sensory system. (Akins does not list Millikan as a traditionalist, but Millikan fits squarely Akins’s description of them, since she believes in a naturalistic theory of aboutness and thinks it should begin with the senses.) For Millikan (1989, 1993), the proper function of a sensory system is in the first instance enabling behavioural systems—in the simplest case, motor routines—to perform their proper function. This they do, roughly, by switching on and steering the behavioural routines. Where features of the outside environment come in is as Normal (= assumed-by-the-design) conditions for the successful performance of the sensory system's proper function. That is, the only strategy for switching on and steering that is simple enough for evolution to have hit upon it, and reliable enough for evolution to have liked it, is a strategy which gears the steering to (values of) features of the outside environment. But as soon as one starts fleshing out the details of this story, one notices that they are probably quite different in the case of thermoreception from how they are with ‘distance’ senses such as vision and olfaction--a point which Akins overlooks..

The property of being the implementation of a computational structure has been argued to be vacuously instantiated. This claim provides the basis for most antirealist arguments in the field of the philosophy of computation. Standard manoeuvres for combating these antirealist arguments treat the problem as endogenous to computational theories. The contrastive analysis of computational and other mathematical representations put forward here reveals that the problem should instead be treated within the more general framework of the Newman problem in structuralist accounts (...) of mathematical representation. It is argued that purely structuralist and purely functionalist accounts of implementation are inadequate to tackle the problem. An extensive evaluation of semantic accounts is provided, arguing that semantic properties are, unlike structural and functional ones, suitable to restrict the intended domain of implementation of computational properties in such a way as to block the Newman problem. The semantic hypothesis is defended from a number of recent objections. (shrink)

Realism, defined as a justified belief in the existence of the external world, is jeopardized by ‘meaning rationalism,’ the classic theory of meaning that sees the extension of words as a function of the intensions of individual speakers, with no way to ensure that these intensions actually correspond to anything in the external world. To defend realism, Ruth Millikan ( 1984 , 1989a , b , 1993 , 2004 , 2005 ) offers a biological theory of meaning called ‘teleosemantics’ in (...) which words, without requiring any contribution from the speaker’s intensions, are supposedly matched directly with their extensions by external norms. But even if one granted as a theoretical possibility that word meaning might possibly be stabilized through an external process, nonetheless, realists who wish to appeal to teleosemantics for a semantic proof of the external world must be capable of identifying these external norms, something that Millikan describes as highly fallible. Furthermore, because they can be aware of these norms only as these are internally represented, it would also be necessary for realists to verify that these internal representations accurately reflect the norms as they occur in the external world. But given that this is virtually the same stumbling block to realism found in meaning rationalism, it is concluded that teleosemantics is not likely to restore faith in this worldview. (shrink)

Within theoretical and empirical enquiries, many different meanings associated with consciousness have appeared, leaving the term itself quite vague. This makes formulating an abstract and unifying version of the concept of consciousness – the main aim of this article –into an urgent theoretical imperative. It is argued that consciousness, characterized as dually accessible (cognized from the inside and the outside), hierarchically referential (semantically ordered), bodily determined (embedded in the working structures of an organism or conscious system), and useful in action (...) (pragmatically functional), is a graded rather than an all-or-none phenomenon. A gradational approach, however, despite its explanatory advantages, can lead to some counterintuitive consequences and theoretical problems. In most such conceptions consciousness is extended globally (attached to primitive organisms or artificial systems), but also locally (connected to certain lower-level neuronal and bodily processes). For example, according to information integration theory (as introduced recently by Tononi and Koch, 2014), even such simple artificial systems as photodiodes possess miniscule amounts of consciousness. The major challenge for this article, then, is to establish reasonable, empirically justified constraints on how extended the range of a graded consciousness could be. It is argued that conscious systems are limited globally by the ability to individuate information (where individuated information is understood as evolutionarily embedded, socially altered, and private), whereas local limitations should be determined on the basis of a hypothesis about the action-oriented nature of the processes that select states of consciousness. Using these constraints, an abstract concept of consciousness is arrived at, hopefully contributing to a more unified state of play within consciousness studies itself. (shrink)

Representations are not only used in our folk-psychological explanations of behaviour, but are also fruitfully postulated, for example, in cognitive science. The mainstream view in cognitive science maintains that our mind is a representational system. This popular view requires an understanding of the nature of the entities they are postulating. Teleosemantic theories face this challenge, unpacking the normativity in the relation of representation by appealing to the teleological function of the representing state. It has been argued that, if intentionality is (...) to be explained in teleological terms, then the function of a state cannot depend on its phylogenetical history, given the metaphysical possibility of a duplicate of an intentional being that lacks an evolutionary history. In this paper, I present a method to produce, according to our current knowledge in genetic engineering, human-like individuals who are not the product of natural selection in the required sense. This variation will be used to shed light on the main replies that have been offered in the literature to the Swampman thought experiment. I argue that these replies are not satisfactory: representations should better not depend on natural selection. I conclude that a non-etiological notion of function is to be preferred for characterizing the relation of representation. (shrink)

In Origins of Objectivity Burge advances a theory of perception according to which perceptions are, themselves, objective representations. The possession of veridicality conditions by perceptual states—roughly, non-propositional analogues of truth-conditions—is central to Burge’s account of how perceptual states differ, empirically and metaphysically, from sensory states. Despite an impressive examination of the relevant empirical literatures, I argue here that Burge has not succeeded in securing a distinction between perception and “mere” sensation.

Cognitive science has recently made some startling discoveries about temporal experience, and these discoveries have been drafted into philosophical service. We survey recent appeals to cognitive science in the philosophical debate over whether time objectively passes. Since this research is currently in its infancy, we identify some directions for future research.

According to “actionism” (Noë 2010), perception constitutively depends on implicit knowledge of the way sensory stimulations vary as a consequence of the perceiver’s self-movement. My aim in this contribution is to develop an alternative conception of the role of action in perception present in the work of Gareth Evans using resources provided by Ruth Millikan’s biosemantic theory of mental representation.

Pictures are 2D surfaces designed to elicit 3D-scene-representing experiences from their viewers. In this essay, I argue that philosophers have tended to underestimate the relevance of research in vision science to understanding the nature of pictorial experience. Both the deeply entrenched methodology of virtual psychophysics as well as empirical studies of pictorial space perception provide compelling support for the view that pictorial experience and seeing face-to-face are experiences of the same psychological, explanatory kind. I also show that an empirically informed (...) account of pictorial experience provides resources to develop a novel, resemblance-based account of depiction. According to what I call the deep resemblance theory, pictures work by presenting virtual models of objects and scenes in phenomenally 3D, pictorial space. (shrink)

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error.

It is a common view that radical contextualism about linguistic meaning is incompatible with a compositional explanation of linguistic comprehension. Recently, some philosophers of language have proposed theories of 'pragmatic' compositionality challenging this assumption. This paper takes a close look at a prominent proposal of this kind due to François Recanati. The objective is to give a plausible formulation of the view. The major results are threefold. First, a basic distinction that contextualists make between mandatory and optional pragmatic processes needs (...) to be revised. Second, the pragmatic theory can withstand a Davidsonian objection only by rejecting the importance of a distinction between primitive and non-primitive semantic items. Thirdly, however, the theory is now open to a worry about how it should be understood: either the theory consists in a very broad functionalist generalization about communication, which makes it explanatorily inert, or it boils down to a highly particularist view about linguistic meaning. Finally, I argue that Recanati's notion of 'occasion meaning' is problematic and suggest replacing it with the notion of speaker meaning, which is explanatorily more basic. (shrink)

Behaviour is often described as the computation of a response to a stimulus. This description is incomplete in an important way because it only examines what occurs between the reception of stimulus information and the generation of an action. Behaviour is more correctly described as a control process where actions are performed in order to affect perceptions. This closed-loop nature of behaviour is de-emphasized in modern discussions of brain function, leading to a number of artificial mysteries. A notable example is (...) the ‘symbol grounding problem'. When behaviour is viewed as a control process, it is natural to explain how internal representations, even symbols, can have meaning for an organism, and how actions can be motivated by organic needs.

Skyrms, building on the work of Dretske, has recently developed a novel information-theoretic account of propositional content in simple signalling systems. Information-theoretic accounts of content traditionally struggle to accommodate the possibility of misrepresentation, and I show that Skyrms’s account is no exception. I proceed to argue, however, that a modified version of Skyrms’s account can overcome this problem. On my proposed account, the propositional content of a signal is determined not by the information that it actually carries, but by the (...) information that it would carry at the nearest separating equilibrium of the underlying evolutionary dynamics. I show that this amended account yields reasonable ascriptions of false propositional content in a well-known formal model of the evolution of communication , and close with a discussion of the serious but perhaps not insuperable difficulties we face in applying the account to examples of signalling in the real world.

In the first part of the paper, I present a framework for the description and evaluation of teleosemantic theories of intentionality, and use it to argue that several different objections to these theories (the various indeterminacy and adequacy problems) are, in a certain precise sense, manifestations of the same underlying issue. I then use the framework to show that Millikan's biosemantics, her own recent declarations to the contrary notwithtanding, presents indeterminacy. In the second part, I develop a novel teleosemantic proposal (...) which makes progress in the treatment of this family of problems. I describe a procedure to derive a (unique) homeostatic property cluster [HPC] from facts having to do with the properties that a certain indicator relied on, in the events leading to its fixation in a certain population. This HPC is the one that should figure in the content attribution to the indicator in question. (shrink)

Alvin Plantinga's evolutionary argument against naturalism makes the case that the conjunction of evolutionary theory and naturalism cannot be rationally believed, as, if both evolutionary theory and naturalism were true, it would be highly unlikely that our cognitive faculties are reliable. I present Plantinga's evolutionary argument against naturalism and survey a theory of meaning espoused by Robert Brandom, known as semantic inferentialism. I argue that if one accepts semantic inferentialism, as it is developed by Brandom, then Plantinga's motivation for the (...) evolutionary argument against naturalism is undermined. (shrink)

Jerry Fodor’s arguments against the possibility of concept learning, and the responses that have been offered in defense of the coherence of concept learning, have both by and large assumed that concept learning is a descriptive process. I offer an alternative, ostensive approach to concept learning and explain how descriptive concept learning can be explained as a version of ostensive concept learning. I argue that an ostensive view of concept learning offers an empirically plausible and philosophically adequate account of concept (...) learning that is explanatorily superior to traditional descriptive views.

Suppose we wish to provide a naturalistic account of intentionality. Like several other philosophers, we focus on the intentionality of belief, hoping that we may later supplement our account to accommodate other intentional states like desires and fears. Now suppose that we also take partial beliefs or credences seriously. In cashing out our favoured theory of intentionality, we may for the sake of simplicity talk as if belief is merely binary or all-or-nothing. But we should be able to supplement or (...) modify our account to accommodate credences. I shall argue, however, that it is difficult to do so with respect to certain causal or teleological theories of intentionality-in particular, those advanced by the likes of Stalnaker (Inquiry, 1984) and Millikan (J Philos 86:281–297, 1989). I shall first show that such theories are tailor-made to account for the intentionality of binary beliefs. Then I shall argue that it is hard to extend or supplement such theories to accommodate credences. Finally, I shall offer some natural ways of modifying the theories that involve an appeal to objective probabilities. But unfortunately, such modifications face problems. (shrink)

I construct a tempting anti-physicalist argument, which sharpens an explanatory gap argument suggested by David Chalmers and Frank Jackson. The argument relies crucially on the premise that there is a deep epistemic asymmetry (which may be identified with the explanatory gap) between phenomenal truths and ordinary macroscopic truths. Many physicalists reject the argument by rejecting this premise. I argue that even if this premise is true, the anti-physicalist conclusion should be rejected, and I provide a detailed, physicalist-friendly explanation of the (...) relevant premise. Along the way, I sketch an account of a priori conceptual knowledge that is compatible with naturalistic accounts of intentionality. I conclude by noting that the resulting view is a version of the popular phenomenal concept strategy that avoids a potentially worrying dilemma facing earlier incarnations of this strategy. (shrink)

Epistemologists and philosophers of mind both ask questions about belief. Epistemologists ask normative questions about belief—which beliefs ought we to have? Philosophers of mind ask metaphysical questions about belief—what are beliefs, and what does it take to have them? While these issues might seem independent of one another, there is potential for an interesting sort of conflict: the epistemologist might think we ought to have beliefs that, according to the philosopher of mind, it is impossible to have. This essay argues (...) that this conflict does arise and that it creates problems for traditional skeptical views in epistemology. In particular, it argues that on certain popular views about the nature of belief, it is impossible to adopt the near-global agnosticism recommended by the skeptical epistemologist. On other plausible views, it is possible only in special circumstances, and this limitation undermines skeptical epistemological claims. The only views about the nature of belief on which there are no metaphysical hurdles to adopting the agnosticism recommended by the skeptic are views that face powerful objections—objections that are completely independent of antiskeptical epistemological considerations.

According to David Chalmers, the hard problem of consciousness consists of explaining how and why qualitative experience arises from physical states. Moreover, Chalmers argues that materialist and reductive explanations of mentality are incapable of addressing the hard problem. In this chapter, I suggest that Chalmers’ hard problem can be usefully distinguished into a ‘how question’ and ‘why question,’ and I argue that evolutionary biology has the resources to address the question of why qualitative experience arises from brain states. From this (...) perspective, I discuss the different kinds of evolutionary explanations (e.g., adaptationist, exaptationist, spandrel) that can explain the origins of the qualitative aspects of various conscious states. This argument is intended to clarify which parts of Chalmers’ hard problem are amenable to scientific analysis. (shrink)

It is a live possibility that certain of our experiences reliably misrepresent the world around us. I argue that tracking theories of mental representation have difficulty allowing for this possibility, and that this is a major consideration against them.

This paper applies the theory of teleosemantics to the issue of moral content. Two versions of teleosemantics are distinguished: input-based and output-based. It is argued that applying either to the case of moral judgements generates the conclusion that such judgements have both descriptive (belief-like) and directive (desire-like) content, intimately entwined. This conclusion directly validates neither descriptivism nor expressivism, but the application of teleosemantics to moral content does leave the descriptivist with explanatory challenges which the expressivist does not face. Since teleosemantics (...) ties content to function, the paper also offers an account of the evolutionary function of moral judgements. (shrink)

This dissertation argues that mental representation is identical to phenomenal consciousness, and everything else that appears to be both mental and a matter of representation is not genuine mental representation, but either in some way derived from mental representation, or a case of non-mental representation.

Mirror neurons and systems are often appealed to as mechanisms enabling mindreading, i.e., understanding other people’s mental states. Such neural mirroring processes are often treated as instances of mental simulation rather than folk psychological theorizing. I will call into question this assumed connection between mirroring and simulation, arguing that mirroring does not necessarily constitute mental simulation as specified by the simulation theory of mindreading. I begin by more precisely characterizing “mirroring” (Sect. 2) and “simulation” (Sect. 3). Mirroring results in a (...) neural process in an observer that resembles a neural process of the same type in the observed agent. Although simulation is often characterized in terms of resemblance (Goldman, Simulating minds: The philosophy, psychology, and neuroscience of mindreading, 2006), I argue that simulation requires more than mere interpersonal mental resemblance: A simulation must have the purpose or function of resembling its target (Sect. 3.1). Given that mirroring processes are generated automatically, I focus on what is required for a simulation to possess the function of resembling its target. In Sect. 3.2 I argue that this resemblance function, at least in the case of simulation-based mindreading, requires that a simulation serve as a representation or stand-in of what it resembles. With this revised account of simulation in hand, in Sect. 4 I show that the mirroring processes do not necessarily possess the representational function required of simulation. To do so I describe an account of goal attribution involving a motor mirroring process that should not be characterized as interpersonal mental simulation. I end in Sect. 5 by defending the conceptual distinction between mirroring and simulation, and discussing the implications of this argument for the kind of neuroscientific evidence required by simulation theory.

Reflections on Meaning refines Paul Horwich’s use theory of meaning. Horwich holds that the meaning of a word is constituted by the nonsemantic property that best explains a certain law. For a given word, the law to be explained governs that word’s use by specifying the “acceptance conditions” of a privileged class of sentences containing the word (26). Horwich devotes considerable energy to details in Reflections on Meaning and focuses on especially pressing problems for his use theory of meaning. As (...) a result the book’s topics run the gamut, and the connections between its chapters are not always strong. Rather than try to provide a synoptic overview, I’ll discuss three areas where it seems further clarification and detail could be fruitful: the distinction between semantic and nonsemantic properties, context sensitivity, and compositionality. Horwich thinks ours is a “fundamentally non-semantic world” (27), making it crucial that meaning be explained in nonsemantic terms. In particular, he insists that we “exclude from the analyzing-properties [of word meaning] anything that would itself require analysis in terms of meaning”: we can’t appeal to reference, belief, or intention, for example (37). But Horwich does not object to “accounts of meaning in psychological terms,” and his own theory relies heavily on a psychological, nonsemantic relation that Horwich calls “acceptance” (37). It’s difficult to see a substantive difference between this technical notion and belief. Acceptance, for Horwich, is “the psychological (but nonsemantic) relation to a sentence that is manifested in our relying on it as a premise in theoretical and practical inference” (40–41). Belief, on the other hand, is a relation with these properties except that it is semantic. Horwich’s other characterizations of acceptance don’t sharpen the distinction very much: “S accepts a sentence just in case that sentence, or its mental correlate, is in S’s belief box” (41); “believing a given proposition is nothing more than accepting some sentence that expresses it” (61)..

Because psychological studies of attention and cognition are most commonly performed within the strict confines of the laboratory or take cognitively impaired patients as subjects, it is difficult to be sure that resultant models of attention adequately account for the phenomenon of effortless attention. The problem is not only that effortless attention is resistant to laboratory study. A further issue is that because the laboratory is the most common way to approach attention, models resulting from such studies are naturally the (...) most widely propagated, these models naturally tend to be biased toward features of attention most amenable to laboratory study, and these models by their implications set the agenda for future study that leads back to the laboratory. In this self-reinforcing system, features of attention not amenable to laboratory study are naturally neglected by researchers. In this chapter, I suggest an alternative model of attention as a heuristic for opening paths to further profitable research. The features of attention emphasized in this model are not new, but the synthesis is novel and sheds some light on issues relevant to the topic of effortless attention. I begin with the five following observations: -/- 1. One naturally pays attention to a task of current interest. 2. There are (at least) two distinct modes of attention—selective and diffuse. 3. Attention is a constantly shifting avenue for the assimilation of information. 4. Information is not forced in from outside but is captured through internal sensitization. 5. Human information processing is fundamentally syntactic. -/- Combining these five observations yields an explanatory model of attention that is not only consistent with the data from the many studies on attention in recent decades but also allows us to investigate the neglected phenomenon of effortless attention. The model relies on the notions of apertures, draw, and syntax and is explicated by addressing each of the above observations in turn. In the final part of the chapter, I explore how the model expands our understanding of effortless attention. (shrink)

The nature of experience has been held to be a major reason for accepting the A-theory of time. I argue, however, that experience does not favour the A-theory over the B-theory; and that even if the A-theory were true it would not be possible to perceive the passage of time. The main argument for this draws on the constraint that a satisfactory theory of perception must explain why phenomenal characters map uniquely onto perceived worldly features. Thus, if passage is perceived, (...) it must be explained what makes one phenomenal character rather than another a perception of passage; and it must also be explained why that phenomenal character is a perception of passage rather than of some other feature of the world. I argue that no such explanation can be given, and consequently that passage cannot be perceived. I conclude that the A-theory is rendered unintelligible, and should therefore be rejected. (shrink)

According to the B-theory, the passage of time is an illusion. The B-theory therefore requires an explanation of this illusion before it can be regarded as fullysatisfactory; yet very few B-theorists have taken up the challenge of trying to provide one. In this paper I take some first steps toward such an explanation by first making a methodological proposal, then a hypothesis about a key element in the phenomenology of temporal passage. The methodological proposal focuses onthe representational content of the (...) element of experience by virtue of which time seems to pass. The hypothesis involves the claim that the experience of changeinvolves the representation of something enduring, rather than perduring, through any change. (shrink)

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)
