We begin by distinguishing computationalism from a number of other theses that are sometimes conflated with it. We also distinguish between several important kinds of computation: computation in a generic sense, digital computation, and analog computation. Then, we defend a weak version of computationalism—neural processes are computations in the generic sense. After that, we reject on empirical grounds the common assimilation of neural computation to either analog or digital computation, concluding that neural computation is sui generis. Analog computation requires continuous (...) signals; digital computation requires strings of digits. But current neuroscientific evidence indicates that typical neural signals, such as spike trains, are graded like continuous signals but are constituted by discrete functional elements (spikes); thus, typical neural signals are neither continuous signals nor strings of digits. It follows that neural computation is sui generis. Finally, we highlight three important consequences of a proper understanding of neural computation for the theory of cognition. First, understanding neural computation requires a specially designed mathematical theory (or theories) rather than the mathematical theories of analog or digital computation. Second, several popular views about neural computation turn out to be incorrect. Third, computational theories of cognition that rely on non-neural notions of computation ought to be replaced or reinterpreted in terms of neural computation. (shrink)

Some philosophers have conflated functionalism and computationalism. I reconstruct how this came about and uncover two assumptions that made the conflation possible. They are the assumptions that (i) psychological functional analyses are computational descriptions and (ii) everything may be described as performing computations. I argue that, if we want to improve our understanding of both the metaphysics of mental states and the functional relations between them, we should reject these assumptions. # 2004 Elsevier Ltd.

The distinction between perception and cognition has always had a firm footing in both cognitive science and folk psychology. However, there is little agreement as to how the distinction should be drawn. In fact, a number of theorists have recently argued that, given the ubiquity of top-down influences, we should jettison the distinction altogether. I reject this approach, and defend a pluralist account of the distinction. At the heart of my account is the claim that each legitimate way of marking (...) a border between perception and cognition deploys a notion I call ‘stimulus-control.’ Thus, rather than being a grab bag of unrelated kinds, the various categories of the perceptual are unified into a superordinate natural kind.

Research on the capacity to understand others' minds has tended to focus on representations ofbeliefs,which are widely taken to be among the most central and basic theory of mind representations. Representations ofknowledge, by contrast, have received comparatively little attention and have often been understood as depending on prior representations of belief. After all, how could one represent someone as knowing something if one does not even represent them as believing it? Drawing on a wide range of methods across cognitive science, (...) we ask whether belief or knowledge is the more basic kind of representation. The evidence indicates that nonhuman primates attribute knowledge but not belief, that knowledge representations arise earlier in human development than belief representations, that the capacity to represent knowledge may remain intact in patient populations even when belief representation is disrupted, that knowledge (but not belief) attributions are likely automatic, and that explicit knowledge attributions are made more quickly than equivalent belief attributions. Critically, the theory of mind representations uncovered by these various methods exhibits a set of signature features clearly indicative of knowledge: they are not modality-specific, they are factive, they are not just true belief, and they allow for representations of egocentric ignorance. We argue that these signature features elucidate the primary function of knowledge representation: facilitating learning from others about the external world. This suggests a new way of understanding theory of mind – one that is focused on understanding others' minds in relation to the actual world, rather than independent from it. (shrink)

The term ‘information’ is used extensively in biology, cognitive science and the philosophy of consciousness in relation to the concepts of ‘meaning’ and ‘causation’. While ‘information’ is a term that serves a useful purpose in specific disciplines, there is much to the concept that is problematic. Part 1 is a critique of the stance that information is an independently existing entity. On this view, and in biological contexts, systems transmit, acquire, assimilate, decode and manipulate it, and in so doing, generate (...) meaning. I provide a detailed proposal in Part 2 that supports the claim that it is the dynamic form of a system that qualifies the informational nature of meaningful interactive engagement, that is, that information is dependent on dynamic form rather than that it exists independently. In Part 3, I reflect on the importance of the distinction between the independent and dependent stances by looking specifically at the implications for how we might better interpret causation and emergence.

The fundamental cognitive problem for active organisms is to decide what to do next in a changing environment. In this article, we analyze motor and action control in computational models that utilize reinforcement learning (RL) algorithms. In reinforcement learning, action control is governed by an action selection policy that maximizes the expected future reward in light of a predictive world model. In this paper we argue that RL provides a way to explicate the so-called action-oriented views of cognitive systems in (...) representational terms. (shrink)

The long history of theorizing about perception divides into two quite distinct and irreconcilable camps, one that takes sensory experience to show us external reality just as it is, and one that takes such experience to reveal our own mind. I argue that we should reject both sides of this debate, and admit that the phenomenal character of experience, as such, reveals little about the nature of the external world and even less about the mind.

My main thesis is this paper is that, although Dretske's distinction between simple perception and cognitive perception constitutes an important milestone in contemporary theorizing on perception, it remains too coarse to account for a number of phenomena that do not seem to fall squarely on either side of the divide. I argue that what is needed in order to give a more accurate account of perceptual phenomena is not a twofold distinction of the kind advocated by Dretske but a threefold (...) distinction allowing for an intermediate level of perceptual content that is structured and yet non-conceptual. In the first section, I discuss Dretske's distinction between sensory perception and cognitive perception as well as a number of attendant notions. In section 2, two sets of phenomena that seem neither to constitute instances of sensory perception nor instances of cognitive perception as defined by Dretske are presented. I argue that they are evidence in favor of the existence of an intermediate level of perception. In section 3, I defend the view that this intermediate level of content is a level of structured non-conceptual perceptual content and I attempt to provide criteria for distinguishing among the three levels of content.

If one compares various skeptical arguments about our perceptual beliefs with arguments against scientific realism one immediately notices important similarities. Skeptical arguments about perceptual beliefs are often based on the premise that all of our perceptual beliefs could be wrong. Our experience is consistent with many different states of affairs; some familiar examples are hallucination, an evil demon, and brains in a vat. Thus it is claimed we have no reason to believe that the perceptual beliefs we normally form are (...) true and alternative beliefs are false.One of the most powerful arguments against scientific realism is based on the claim that our data underdetermines our theory. There exist empirically equivalent theories, which means that there is no observation that could lead us to accept one and reject the other. Each member of a class of empirically equivalent theories will be equally supported by the evidence. (shrink)

In this paper, I discuss two influential pictures of communication and the relation between them. One picture holds that successful communication requires identity of content: The speaker has a belief that she expresses with her utterance, and the hearer acquires a belief with the same content by understanding the utterance. The second picture was proposed by Lewis in his classic work Convention and then refined in “Languages and Language.” It sees communication as coordination among speakers—a technical notion that Lewis draws (...) from game theory. Samuel Cumming has recently provided an elegant and insightful synthesis of the two pictures, arguing that Lewisian coordination among speakers is in fact a form of content identity. In this paper, my negative goal is to argue against Cumming’s attempt to construe coordination as content identity, showing that it yields incorrect predictions about certain cases of successful communication. My positive goal is to show how we can avoid Cumming’s problematic interpretation of coordination and still do justice to the relevant data within a coordination-based framework. (shrink)

A substantial literature supports the attribution of intentional states such as beliefs and desires to groups. But within this literature, there is no substantial account of group concepts. Since on many views, one cannot have an intentional state without having concepts, such a gap undermines the cogency of accounts of group intentionality. In this paper I aim to provide an account of group concepts. First I argue that to fix the semantics of the sentences groups use to make their decisions (...) or express their beliefs, we need to appeal to a conventional semantics like that of Lewis. I then argue that the same reasons we have for taking group intentional states to be irreducible to the intentional states of their members apply also to the terms fixed by a conventional semantics. It follows that the meanings of terms in the sentences expressing a group's intentional states are also fixed by facts about the group, not its members. And recognizing this, I argue, amounts to attributing concepts to groups. Finally, I discuss a real-life example of a group concept—the meaning of ‘meter’ as fixed by the International Bureau of Weights and Measurements—and I discuss the upshot of these considerations for the question of social externalism about concepts.

Jim buys a ticket in a million-ticket lottery. He knows it is a fair lottery, but, given the odds, he believes he will lose. When the winning ticket is chosen, it is not his. Did he know his ticket would lose? It seems that he did not. After all, if he knew his ticket would lose, why would he have bought it? Further, if he knew his ticket would lose, then, given that his ticket is no different in its chances (...) of winning from any other ticket, it seems that by parity of reasoning he should also know that every other ticket would lose. But of course he doesn’t know that; in fact, he knows that not every ticket will lose. (shrink)

In this article, I discuss whether intuitive moral judgements have epistemic value. Are they mere expressions of irrational feelings that should be disregarded or should they be taken seriously? In section 2, I discuss the view of some social psychologists that moral intuitions are, like other social intuitions, under certain conditions more reliable than conscious deliberative judgements. In sections 3 and 4, I examine whether intuitive moral judgements can be said not to need inferential justification. I outline a concept of (...) moral intuition as a seeming whose seemingness resides in special, phenomenological features such as a felt veridicality, appropriateness, familiarity, or confidence, and whose justificatory force is influenced by the reliability of the belief-producing procedures and by a subject's competence in applying moral concepts. I argue that subjects can come to realise that the beliefs expressed in their intuitive judgements evoke a sense of non-inferential credibility. In section 5, I first discuss the contribution of moral expertise to the non-inferential credibility of a person's intuitions. Subsequently, I discuss whether Walter Sinnott-Armstrong is right in saying that we can never claim non-inferential justification for our intuitions because they are subject to all kinds of distorting influences.

I identify three aspects to the puzzle of the speckled hen: A general puzzle, an epistemic puzzle, and a puzzle for the representationalist. These puzzles rely on an underlying “pictorialist” assumption, that we visually perceive general, determinable properties only in virtue of determinate properties or more specific, local features of our visual experience. This assumption is mistaken: Visual perception frequently starts from a position of uncertainty, and is routinely able to acquire information about general properties in the absence of more (...) specific information. Acknowledging that visual indeterminacy is structured this way resolves all three puzzles of the speckled hen. (shrink)

Some have claimed that there are laws of appearance, i.e. in principle constraints on which types of sensory experiences are possible. Within a representationalist framework, these laws amount to restrictions on what a given experience can represent. I offer an in-depth defence of one such law and explain why prevalent externalist varieties of representationalism have trouble accommodating it. In light of this, I propose a variety of representationalism on which the spatial content of experience is determined by intrinsic features of (...) conscious subjects. I conclude by considering an externalist-friendly reworking of my proposal, but suggest that the success of such a reworking is dubious. (shrink)

I use an old challenge to motivate a new view. The old challenge is due to variation in our perceptions of secondary qualities. The challenge is to say whose perceptions are accurate. The new view is about how we manage to perceive secondary qualities, and thus manage to perceive them accurately or inaccurately. I call it perceptual structuralism. I first introduce the challenge and point out drawbacks with traditional responses. I spend the rest of the paper motivating and defending a (...) structuralist response. While I focus on color, both the challenge and the view generalize to the other secondary qualities. (shrink)

This essay argues for a two-part thesis concerning the deflationist theories of truth and reference. First, I identify two points of contrast between the deflationist theories and their traditional inflationary opponents: (1) they each employ different orders of explanation for the variety of semantic phenomena, and (2) the inflationist is typically taken to be beholden to a reductive explanation of reference, whereas the deflationist is doubtful of this project. Secondly, I argue that these two points of contrast need not come (...) together to exhaust the space of possible views. There is room for a plausible middle ground: a moderate version of inflationism. My moderate inflationism will reject the deflationist's order of explanation, so it counts as genuinely inflationary. However, it also rejects the reductionist ambitions of the earlier inflationists, so it isn’t an apt target for deflationary scepticism. (shrink)

In Word and Object, W.V. Quine made thinkable the idea that speech and cognition bear a burden of semantic indeterminacy. On Quine’s account, the upshot of semantic indeterminacy is that meaning and mentalism resist successful naturalization, and thus fail the test of scientific respectibility. For Quine, semantic indeterminacy is a fatal shortcoming.Recent attempts to naturalize meaning in our thought and our talk (e.g. Dretske 1981, Fodor 1987), belonging to a tradition that has thrived in reaction to Quine, have sought to (...) nail down semantic properties in a scientifically respectable fashion, avoiding the scourge of indeterminacy. However, both Quine and the new redeemers of mentalism may have missed the boat. Three case studies offered here will suggest that a thriving theory of visual perception still makes room for some rather striking indeterminacies. (shrink)

Debate on the nature of representation in cognitive systems tends to oscillate between robustly realist views and various anti‐realist options. I defend an alternative view, deflationary realism, which sees cognitive representation as an offshoot of the extended application to cognitive systems of an explanatory model whose primary domain is public representation use. This extended application, justified by a common explanatory target, embodies idealisations, partial mismatches between model and reality. By seeing representation as part of an idealised model, deflationary realism avoids (...) the problems with robust realist views, while keeping allegiance to realism. (shrink)

In the literature on the nature and role of cognitive representation, three positions are taken across the conceptual landscape: robust realism, primitivism, and eliminativism. Recently, a fourth alternative that tries to avoid the shortcomings of traditional views has been proposed: content pragmatism. My aim is to defend pragmatism about content against some recent objections moved against the view. According to these objections, content pragmatism fails to capture the role played by representation in the cognitive sciences; and/or is an unstable view (...) that ends up collapsing into one of the traditional alternatives. I argue that those arguments fail. I show that content pragmatism has as much claim to descriptive adequacy as the traditional theories. Moreover, I defend the robustness of the view by arguing that it does not collapse into any of the traditional positions. Content pragmatism therefore offers a valid and coherent account of the nature of representational content. (shrink)

‘According to informational semantics, if it's necessary that a creature can't distinguish Xs from Ys, it follows that the creature can't have a concept that applies to Xs but not Ys.’ There is, indeed, a form of informational semantics that has this verificationist implication. The original definition of information given in Dretske'sKnowledge and the Flow of Information, when employed as a base for a theory of intentional representation or ‘content,’ has this implication. I will argue that, in fact, most of (...) what an animal needs to know about its environment is not available as natural information of this kind. It is true, I believe, that there is one fundamental kind of perception that depends on this kind of natural information, but more sophisticated forms of inner representation do not. It is unclear, however, exactly what ‘natural information’ is supposed to mean, certainly in Fodor's, and even in Dretske's writing. In many places, Dretske seems to employ a softer notion than the one he originally defines. I will propose a softer view of natural information that is, I believe, at least hinted at by Dretske, and show that it does not have verificationist consequences. According to this soft informational semantics, a creature can perfectly well have a representation of Xs without being able to discriminate Xs from Ys. (shrink)

One argument for the moving spotlight theory is that it better explains certain aspects of our temporal phenomenology than does any static theory of time. Call this the argument from passage phenomenology. In this paper it is argued that insofar as moving spotlight theorists take this to be a sound argument they ought embrace a new version of the moving spotlight theory according to which the moving spotlight is a cresting wave of causal efficacy. On this view it is more (...) than just presentness that is temporary: a range of other fundamental properties are also temporary because presentness synchronically changes the fundamental properties that are instantiated in the present moment, from those instantiated when that moment is future, or past. On this view having experiences as of presentness co-varies with the presence of presentness, allowing the moving spotlight theorist to provide a compelling explanation for why we have the temporal phenomenology we do, and to explain how we can know that we are present by reflecting on the nature of said phenomenology.

We distinguish between different problems of “aboutness”: the “hard” problem of explaining the everyday phenomenon of intentionality and three less challenging “easy” sets of problems concerning the posits of folk psychology, the notions of representation invoked in the mind‐brain sciences, and the intensionality (with an “s”) of mental language. The problem of intentionality is especially hard in that, as is the case with the hard problem of phenomenal consciousness, there is no clear path to a solution using current methods. We (...) argue that naturalistic theories of mental representation do not address the hard problem—either they are only intended to address the easy problems, or the claims they make help address the problem of intentionality only under undefended and prima facie implausible assumptions to the effect that the hard problem reduces to some combination of the easy problems. We offer a positive account of what would be required to properly face up to the problem of intentionality. (shrink)

It is often assumed that when we see common opaque objects in standard light this is in virtue of seeing their facing surfaces. Here I argue that we should reject that claim. Either we don't see objects' facing surfaces, or—if we hold on to the claim that we do see such things—it is at least not in virtue of seeing them that we see common opaque objects. I end by showing how this conclusion squares both with our intuitions and with (...) the facts of vision science. (shrink)

Kriegel’s self-representationalist theory of phenomenal consciousness pursues two projects. The first is to offer a positive account of how conscious experience arises from physical brain processes. The second is to explain why consciousness misleadingly appears to be irreducible to the physical i.e. to ‘demystify’ consciousness. This paper seeks to determine whether SR succeeds on the second project. Kriegel trades on a distinction between the subjective character and qualitative character of conscious states. Subjective character is the property of being a conscious (...) state at all, while qualitative character determines what it is like to be in that state. Kriegel claims that SR explains why subjective character misleadingly appears irreducible, thereby neutralising the apparent irreducibility of consciousness. I argue that although SR credibly demystifies subjective character, it cannot explain why qualitative character also appears irreducible. I conclude that we should pursue the possibility of a hybrid position that combines SR with an account that does explain the apparent irreducibility of qualitative character. (shrink)

There are many accounts of representation in the philosophical literature. However, regarding olfaction, Burge’s (2010) account is widely endorsed. According to his account, perceptual representation is always of an objective reality, that is, perception represents objects as such. Many authors presuppose this account of representation and attempt to show that the olfactory system itself issues in representations of that sort. The present paper argues that this myopia is a mistake and, moreover, that the various arguments in favor of olfactory objects (...) fail. Yet, by taking seriously a minimal notion of representation, adopted from Shea (2018), we can see that the olfactory system is representational after all even if it doesn’t represent objects as such. That is, olfaction issues in minimal representations. Crucially, however, this paper will conclude with an argument to the effect that olfactory object files (objectual representations of olfactory objectual properties) are constructed by interactions between various mental systems. The claim to be defended is that objectual representations of olfactory objects are constructed when minimal olfactory content is embedded in object-files that contain other non-olfactory properties that meet Burge’s criteria for representation. Some extant work on feature-binding, attention, and object-files will be introduced to support the suggestion. (shrink)

Many psychologists think that concepts should be understood on analogy with the terms of scientific theories, yet the significance of this claim has always been obscure. In this paper, I clarify the psychological content of the theory analogy, focusing on influential pieces by Susan Carey. Once plainly put, the analogy amounts to the view that a mental representation has its semantic properties by virtue of its role in a restricted knowledge structure. One of the commendable things about Carey's work is (...) that, unlike many other psychologists who appeal to the theory analogy, she takes seriously the need to specify how these structures are constrained. At the same time, the constraints she offers are insufficient. Her account also faces challenges from work in the semantics of natural kind terms. (shrink)

Information is widely perceived as essential to the study of communication and representation; still, theorists working on these topics often take themselves not to be centrally concerned with "Shannon information", as it is often put, but with some other, sometimes called "semantic" or "nonnatural",kind of information. This perception is wrong. Shannon's theory of information is the only one we need. -/- I intend to make good on this last assertion by canvassing a fully (Shannon) informational answer to the metasemantic question (...) of what makes something a representation, for a certain important family of cases. This answer and the accompanying theory, which represents a significant departure from the broadly Dretskean philosophical mainstream, will show how a number of threads in the literature on naturalistic metasemantics, aimed at describing the purportedly non-informational ingredients in representation, actually belong in the same coherent, purely information-theoretic picture.

This paper aims to establish several interconnected points. First, a particular interpretation of the mathematical definition of information, known as the causal interpretation, is supported largely by misunderstandings of the engineering context from which it was taken. A better interpretation, which makes the definition and quantification of information relative to the function of its user, is outlined. The first half of the paper is given over to introducing communication theory and its competing interpretations. The second half explores three consequences of (...) the main thesis. First, a popular claim that the quantification of information in a signal is irrelevant for the meaning of that signal is exposed as fallacious. Second, a popular distinction between causal and semantic information is shown to be misleading, and I argue it should be replaced with a related distinction between natural and intentional signs. Finally, I argue that recent empirical work from microbiology and cognitive science drawing on resources of mathematical communication theory is best interpreted by the functional account. Overall, a functional approach is shown to be both theoretically and empirically well-supported. (shrink)

A received criticism of information is that it is an instrumentalization of knowledge. This article questions the conditions for such a critique. Examining developmental systems theory, biology and social sciences, it argues that information is a situated event; that it is intrinsic to the development and structuring of mnemic organization at a number of levels; and that such developmental systems are epigenetically constituted. This concept of information leads to: a critique of the statistical-quantitative determination of information that is put forward (...) as its mathematical theorization; a review of characterizations of ‘information societies’; and comprehending instrumentalization as a variant of the event of information at the specific level of the constitution of the human understood as an anthropotechnical complex.

Representationalism is the position that the phenomenal character of an experience is either identical with, or supervenes on, the content of that experience. Many representationalists hold that the relevant content of experience is nonconceptual. I propose a counterexample to this form of representationalism that arises from the phenomenon of Gestalt switching, which occurs when viewing ambiguous figures. First, I argue that one does not need to appeal to the conceptual content of experience or to judgements to account for Gestalt switching. (...) I then argue that experiences of certain ambiguous figures are problematic because they have different phenomenal characters but that no difference in the nonconceptual content of these experiences can be identified. I consider three solutions to this problem that have been proposed by both philosophers and psychologists and conclude that none can account for all the ambiguous figures that pose the problem. I conclude that the onus is on representationalists to specify the relevant difference in content or to abandon their position. (shrink)

This paper argues that functionalist metasemantic views, such as Conceptual Role Semantics and Interpretivism, face a Euthyphro challenge. The challenge, put roughly, is this: functionalist metasemantic views reverse the order of explanation. According to such views, representational mental states have the contents that they do partly because they play certain roles in our mental lives. According to an intuitive picture of the roles that representational mental states play in our mental lives, however, these states play the roles they do partly (...) because they have the contents that they do. Since explanations—even partial ones—are asymmetric (call this principle ‘the Euthyphro Principle’), we can’t accept both this intuitive picture and a functionalist metasemantics. Hence, we should reject all versions of the latter. This paper can be seen as an attempt to better articulate an intuition that has been suggested in various forms in the literature. The paper proceeds as follows. First, it shows that functionalist metasemantic views imply certain ‘partly because’ claims. Second, it argues for the Euthyphro Principle. Third, it defends the intuitive picture of representational mental states and shows that it implies ‘partly because’ claims that conflict with those made by functionalist metasemantic views. Finally, it considers ways of relaxing the intuitive picture and finds them all wanting. (shrink)

As a field of scientific expertise, semiotics has the interesting property of being a relevant tool for understanding how scientists represent any domain of research, including the semiotic domain itself. This feature is particularly expressive in the case of biology, as it appears to be the case that a certain range of biological phenomena are of a semiotic character. However, it is not consensual the extent to which semiotics pervades biology. This paper deals with this issue for the particular case (...) of developmental biology, stressing the role of semiotics-as-a-discipline in delimiting the extent of semiotics-as-a-natural-phenomenon and, specifically, in disentangling semiotic mechanisms from semiotic metaphors aimed at clarifying non-semiotic developmental mechanisms.

The aim of the present article is to accomplish two things. The first is to show that given some further plausible assumptions, existing challenges to the indispensability of knowledge in causal explanation of action fail. The second is to elaborate an overlooked and distinct argument in favor of the causal efficacy of knowledge. In short, even if knowledge were dispensable in causal explanation of action, it is still indispensable in causal explanation of other mental attitudes and, in particular, some reactive (...) attitudes and factive emotions. Taking into account this sort of causal efficacy in determining which mental states are genuine mental states opens up new perspectives for defending the view that knowledge is the most general factive and genuine mental state.

A variety of recent work in epistemology employs a notion of normality to provide novel theories of knowledge or justification. While such theories are commonly advertised as affording particularly strong epistemic logics, they often make substantive assumptions about the background notion of normality and its logic. This article takes recent normality-based defences of the KK principle as a case study to submit such assumptions to scrutiny. After clarifying issues regarding the natural language use of normality claims, the article isolates a (...) number of choice points regarding the role of contingency, context-sensitivity and similarity in our theorizing with normality. It turns out that both weaker and stronger logics of normality can be motivated depending on how such choices are resolved. And yet securing logics of normality strong enough for normality to play its envisaged role in epistemology may have unwelcome downstream consequences for the resultant theories of knowledge or justification.

Representationalism is a philosophical position which reduces all phenomenal conscious states to intentional states. However, starting from the phenomenal consciousness, the phenomenal intentionality theory provides an explanation of all sorts of intentionality. Against Michael Shim's interpretation, I argue that, although Hussserl's phenomenology is certainly considered as an antipode of strong representationalism, Husserl does not stand in opposition the weak representationalists, because Husserl maintains an essential connection between the senses of noemata and the hyletic data. In addition, Husserl's phenomenology is also (...) consistent with the phenomenal theory of intentionality. According to him, statically and genetically, all non-phenomenal intentional states take a recourse to phenomenal intentional states and eventually to sensual perceptions. (shrink)

Aristotle’s theory of causes requires a first, unmoved mover outside the sublunary world, along with soul as first and unmoved mover in the natural world below. Aristotle separates the charmed group of causes headed by soul that are jointly sufficient for typical animal behaviour from external causes. The border between external and charmed is permeable: crops growing in the field are co-opted to become an instrument of soul that nourishes the animal. (Instruments of soul like the sumphuton pneuma are internal (...) to the animal from the start.) But no causes, not even the Unmoved Mover, may supersede soul as unmoved mover. (shrink)

In this paper I propose a model of demonstrative thought. I distinguish token-demonstratives, that pick out individuals, from type-demonstratives, that pick out kinds, or properties, and provide a similar treatment for both. I argue that it follows from my model of demonstrative thought, as well as from independent considerations, that demonstration, as a mental act, operates directly on mental representations, not external objects. That is, though the relation between a demonstrative and the object or property demonstrated is semantically direct, the (...) mechanism by which a demonstrative acquires its referent involves mediation by a perceptual representation. Finally, I argue that so-called 'demonstrative concepts'—which I treat as type-demonstratives—cannot perform the various philosophical functions that have been assigned to them. (shrink)

A promising strategy for defending the role that representation plays in explanations of cognition frames the concept in terms of internal models or map‐like mechanisms. “Structural representation” offers an account of representation that is grounded in well‐specified, empirical criteria. However, anti‐representationalists continue to press the issue of how to account for the paradigmatic semantic properties of representation at the subpersonal level. In this paper, I offer an account of how the proponent of structural representation should think about content. There are (...) really two problems of content any account of representation must overcome: the “hard problem of content” and the “content determination problem.” I argue that the structural representation account has the resources to provide a naturalistically respectable notion of content that overcomes both problems.

In recent years, the ‘mechanistic view’ has developed as a popular alternative to the ‘semantic view’ concerning the identity of physical computation. However, semanticists have provided powerful arguments that suggest the mechanistic view fails to deliver essential distinctions between paradigmatic computational operations. This article reviews responses on behalf of the mechanist and uses this opportunity to propose a type of pluralism about computational identity. This pluralism contends that there are multiple ‘levels’ of properties and relations pertaining to computation that can (...) inform different kinds of individuation. As such, for the pluralist, there are multiple legitimate ways of classifying computation, depending on the nature of the system in question, and one’s own epistemic priorities. (shrink)

In the mental files framework, mental files contain pieces of information. Then, how can we explain the fact that multiple pieces of information are stored in a single mental file? This fact can be called ‘co-filing’. Recanati recommends an account of co-filing as a way to avoid the circularity that can occur when one attempts to explain co-filing in terms of the fact that pieces of information are taken to be about the same object. I argue that his account is (...) far from being satisfactory and that co-filing needs to be regarded as a primitive fact. In other words, co-filing is not what needs to be explained within the mental files framework. The right question to be dealt with is what we can explain based on co-filing. (shrink)

Conceptual analysis is undergoing a revival in philosophy, and much of the credit goes to Frank Jackson. Jackson argues that conceptual analysis is needed as an integral component of so-called serious metaphysics and that it also does explanatory work in accounting for such phenomena as categorization, meaning change, communication, and linguistic understanding. He even goes so far as to argue that opponents of conceptual analysis are implicitly committed to it in practice. We show that he is wrong on all of (...) these points and that his case for conceptual analysis doesn't succeed. At the same time, we argue that the sorts of intuitions that figure in conceptual analysis may still have a significant role to play in philosophy. So naturalists needn't disregard intuitions altogether. (shrink)

Embodied, embedded, enactive, and extended theorists do not typically focus on the ontological frameworks in which they develop their theories. One exception is 4E theories that embrace New Mechanism. In this paper, we endorse the New Mechanist’s general turn to ontology, but argue that their ontology is not the best on the market for 4E theories. Instead, we advocate for a different ontology: causal powers realism. Causal powers realism posits that psychological manifestations are the product of mental powers, and that (...) mental powers are empirically-discoverable features of individuals that account for the causal work those individuals do. We contend that causal powers realism provides a unifying framework for the central commitments of 4E theories, as well as additional resources for theorizing in a 4E framework. And while New Mechanism offers some of these resources as well, we argue that causal powers realism is ultimately the better of the two. (shrink)

An ongoing philosophical discussion concerns how various types of mental states fall within broad representational genera—for example, whether perceptual states are “iconic” or “sentential,” “analog” or “digital,” and so on. Here, I examine the grounds for making much more specific claims about how mental states are structured from constituent parts. For example, the state I am in when I perceive the shape of a mountain ridge may have as constituent parts my representations of the shapes of each peak and saddle (...) of the ridge. More specific structural claims of this sort are a guide to how mental states fall within broader representational kinds. Moreover, these claims have significant implications of their own about semantic, functional, and epistemic features of our mental lives. But what are the conditions on a mental state's having one type of constituent structure rather than another? Drawing on explanatory strategies in vision science, I argue that, other things being equal, the constituent structure of a mental state determines what I call its distributional properties—namely, how mental states of that type can, cannot, or must co‐occur with other mental states in a given system. Distributional properties depend critically on and are informative about the underlying structures of mental states, they abstract in important ways from aspects of how mental states are processed, and they can yield significant insights into the variegation of psychological capacities.
