Can animals think? In this paper I address the proposal that many animals, including insects such as honeybees, have genuine thoughts. I consider one prominent version of this view that claims that honeybees can represent and process information about their environments in a way that satisfies the main hallmarks of human conceptual thought. I shall argue, however, that this view fails to provide convincing grounds for accepting that animals possess concepts. More precisely, I suggest that two important aspects of conceptual (...) thought, viz., concept individuation and the generality constraint, are not satisfied. (shrink)

In this paper I argue that, by combining eliminativist and fictionalist approaches toward the sub-personal representational posits of predictive processing, we arrive at an empirically robust and yet metaphysically innocuous cognitive scientific framework. I begin the paper by providing a non-representational account of the five key posits of predictive processing. Then, I motivate a fictionalist approach toward the remaining indispensable representational posits of predictive processing, and explain how representation can play an epistemologically indispensable role within predictive processing explanations without thereby (...) requiring that representation metaphysically exists. Finally, I outline four consequences of accepting this approach and explain why they are beneficial: we arrive at a victory for metaphysical eliminativism in the ‘representation wars’; my account fits with extant empirical practice; my account provides guidance for future research; and, my account provides the beginnings of a response to Mark Sprevak’s IBE problem for fictionalist approaches toward sub-personal representation.

The papers in this special issue make important contributions to a longstanding debate about how we should conceive of and explain mental phenomena. In other words, they make a case about the best philosophical paradigm for cognitive science. The two main competing approaches, hotly debated for several decades, are representationalism and enactivism. However, recent developments in disciplines such as machine learning and computational neuroscience have fostered a proliferation of intermediate approaches, leading to the emergence of completely new positions, in particular (...) the Predictive Processing approach. Here, we will consider the different approaches discussed in this volume. (shrink)

Hume said that to have a memory image of some individual, x, is to perceive a ‘faint copy’ of some prior perception of x. This classical view of memory images includes three distinct claims: Images and percepts are mental entities which serve as objects for a ‘direct’ or ‘non-inferential’ perception. A memory image of some individual, x, shares numerous properties with some prior perception of x.

This paper explores how words relate to concepts. It argues that in many cases, words get their meanings in part by associating with concepts, but only in conjunction with substantial input from language. Language packages concepts in grammatically determined ways. This structures the meanings of words, and determines which sorts of concepts map to words. The results are linguistically modulated meanings, and the extralinguistic concepts associated with words are often not what intuitively would be expected. The paper concludes by discussing (...) implications of this thesis for the relation of word to sentence meaning, and for issues of linguistic determinism. (shrink)

In this dissertation, I provide an interpretation and defense of Merleau-Ponty's thesis of the primacy of perception, namely, the thesis that all knowledge is founded in perceptual experience. I take as an interpretative and argumentative key Merleau-Ponty's phenomenological conception of motivation. Whereas epistemology has traditionally accepted a dichotomy between reason and natural causality, I show that this dichotomy is not exhaustive of the forms of epistemic grounding. There is a third type of grounding, the one characteristic of the grounding relations (...) found in perception: motivation. I argue that introducing motivation as a form of epistemic grounding allows us to see how Merleau-Ponty's thesis of the primacy of perception avoids both rationalism and empiricism. Whereas empiricism has argued that all the content of our knowledge is grounded in causal interactions between the world and our senses, and rationalism has held that experience does not suffice as a reason for knowledge, thinking of the relation between experience and knowledge in terms of motivation accommodates the best insights of rationalism and empiricism. Motivation allows us to see how knowledge can be grounded in experience without the content of knowledge being reducible to that of experience. (shrink)

Colors are of philosophical interest for two kinds of reason. One is that colors comprise such a large and important portion of our social, personal and epistemological lives and so a philosophical account of our concepts of color is highly desirable. The second reason is that trying to fit colors into accounts of metaphysics, epistemology and science leads to philosophical problems that are intriguing and hard to resolve. Not surprisingly, these two kinds of reasons are related. The fact that colors (...) are so significant in their own right, makes more pressing the philosophical problems of fitting them into more general metaphysical and epistemological frameworks.

Jerry Fodor argues that Darwin was wrong about "natural selection" because (1) it is only a tautology rather than a scientific law that can support counterfactuals ("If X had happened, Y would have happened") and because (2) only minds can select. Hence Darwin's analogy with "artificial selection" by animal breeders was misleading and evolutionary explanation is nothing but post-hoc historical narrative. I argue that Darwin was right on all counts. Until Darwin's "tautology," it had been believed that either (a) God (...) had created all organisms as they are, or (b) organisms had always been as they are. Darwin revealed instead that (c) organisms have heritable traits that evolved across time through random variation, with survival and reproduction in (changing) environments determining (mindlessly) which variants were successfully transmitted to the next generation. This not only provided the (true) alternative (c), but also the methodology for investigating which traits had been adaptive, how and why; it also led to the discovery of the genetic mechanism of the encoding, variation and evolution of heritable traits. Fodor also draws erroneous conclusions from the analogy between Darwinian evolution and Skinnerian reinforcement learning. Fodor’s skepticism about both evolution and learning may be motivated by an overgeneralization of Chomsky’s “poverty of the stimulus argument” -- from the origin of Universal Grammar (UG) to the origin of the “concepts” underlying word meaning, which, Fodor thinks, must be “endogenous,” rather than evolved or learned.

In this paper we propose a narrative hypothesis on the nature of language and a proto-discursive hypothesis on the origin of our communicative abilities. Our proposal is based on two assumptions. The first assumption, concerning the properties of language, is tied to the idea that global discourse coherence governs the origin of our communicative abilities as well the functioning of these abilities. The second assumption, concerning processing devices, is connected to the idea that the systems of spatial and temporal navigation (...) are implicated in discourse coherence processing. Analysis of the relationship between these two assumptions allows us to integrate the model of language based on clues proposed by Sperber and Wilson with Relevance Theory with the discursive foundation of human communication. In this respect, our proposal can be considered as a tentative extension of Relevance Theory. (shrink)

Cognitive pragmatics is concerned with the mental processes involved in intentional communication. I discuss a few issues that may help clarify the relationship between this area and the broader cognitive science and the contribution that they give, or might give, to each other. Rather than dwelling on the many technicalities of the various theories of communication that have been advanced, I focus on the different conceptions of the nature and the architecture of the mind/brain that underlie them. My aims are, (...) first, to introduce and defend mentalist views of communication in general; second, to defend one such view, namely that communication is a cognitive competence, that is, a faculty, and the underlying idea that the architecture of the mind/brain is domain-specific; and, third, to review the (scarce) neuropsychological evidence that bears on these issues.

Are minds really dynamical or are they really symbolic? Because minds are bundles of computations, and because computation is always a matter of interpretation of one system by another, minds are necessarily symbolic. Because minds, along with everything else in the universe, are physical, and insofar as the laws of physics are dynamical, minds are necessarily dynamical systems. Thus, the short answer to the opening question is “yes.” It makes sense to ask further whether some of the computations that constitute (...) a human mind are constrained by functional, algorithmic, or implementational factors to be essentially of the discrete symbolic variety (even if they supervene on an apparently continuous dynamical substrate). I suggest that here too the answer is “yes” and discuss the need for such discrete, symbolic cognitive computations in communication-related tasks. (shrink)

In recent years, a number of well-known intentional realists have focused their energy on attempts to provide a naturalized theory of mental representation. What tends to be overlooked, however, is that a naturalized theory of mental representation will not, by itself, salvage intentional realism. Since most naturalistic properties play no interesting causal role, intentional realists must also solve the problem of showing how intentional properties , even if naturalized, could be causally efficacious. Because of certain commitments, this problem is especially (...) difficult for intentional realists such as Fodor. In the current paper I focus on the problem as it arises for such realists, and I argue that the best-known solution proposed to date is inadequate. If what I say is correct, then such intentional realists are left with an additional and substantial problem, and one that has generally not been sufficiently appreciated. (shrink)

This article is about the special, subjective concepts we apply to experience, called “phenomenal concepts”. They are of special interest in a number of ways. First, they refer to phenomenal experiences, and the qualitative character of those experiences whose metaphysical status is hotly debated. Conscious experience strike many philosophers as philosophically problematic and difficult to accommodate within a physicalistic metaphysics. Second, PCs are widely thought to be special and unique among concepts. The sense that there is something special about PCs (...) is very closely tied up with features of the epistemic access they afford to qualia. When we deploy phenomenal concepts introspectively to some phenomenally conscious experience as it occurs, we are said to be acquainted with our own conscious experiences. Accounts of PCs either have to explain the acquaintance relation, or acquaintance with our phenomenal experiences has to be denied. PCs have received much attention in recent philosophy of mind mainly because they figure in arguments for dualism and in physicalist responses to these arguments. The main topic of this article is to explore different accounts of phenomenal concepts and their role in recent debates over the metaphysical status of phenomenal consciousness. (shrink)

The enactive approach to cognition and consciousness offers a valuable alternative to the standard approaches dominant in the sciences of mind. As an embodied account, enactivism incorporates theoretical perspectives on the body from phenomenology, cognitive science, and biology, which provides a unique interpretation of embodiment with critical insight into the embodied nature of cognition and consciousness. Nonetheless, I argue that several revisions are required to make enactivism viable within the context of the sciences of mind. The enactive account of subjectivity (...) is problematic, in light of arguments developed in Maurice Merleau-Ponty’s later texts, because it is implicitly dualistic. I demonstrate that this implicit dualism can be resolved by incorporating the conceptual framework of flesh that Merleau-Ponty introduces in his later works. However, this new framework presents a challenge of understanding how body can break with world in experience. I provide a solution to this problem by way of developing revisions to the enactive account of cognition, which I argue is problematic in its generality. I offer a new interpretation of enactive cognition modelled on structural flexibility that overcomes the difficulties of the previous account. These revisions to enactive cognition provide a way of understanding how body can break with world, resulting in an account of the enactive body as expressing a massive integration of its different ways of being in the world, as cognitive, conscious, affective, and agentive. These revisions provide a more consistent and plausible articulation of the enactive approach that is more amenable to guiding the sciences of mind. (shrink)

According to the traditional view, beliefs and desires are mental representations that play particular functional roles. A belief that P is state which represents P and plays the belief-role, while a desire that P is a state which represents that P and plays the desire-role. In this dissertation I argue that the traditional view has trouble accounting for (a) role that belief and desire play in the causal and rational explanation of behaviour and (b) our knowledge of our own conscious, (...) occurrent beliefs and desires. -/- In its place I argue for Pure Attitude Representationalism (PAR), which holds that beliefs and desires are not to be distinguished from one another by their functional role, but instead entirely by their representational content. According to PAR, desires are distinct from beliefs not because they do different things, but because desires represent things as being rewarding. Throughout the three papers that comprise this dissertation I argue that PAR provides a better explanation of (a) and (b). (shrink)

Part 1 of the thesis questions the traditional relation model of intentionality. After fixing reference on the target phenomenon, intentionality, and explaining my interest in it, I ask what sorts of things intentionality might be a relation to. I consider ordinary objects, properties, propositions and hybrid views, and conclude all make the intentional relation appear rather mysterious. From there, I move on to examine the relation view’s most prominent proponents, the tracking theorists—pointing out some challenges such views face, and concluding (...) that it might be worthwhile looking into alternatives to the relation view. Part 2 asks whether the newly emerging phenomenal intentionality movement can provide a viable alternative to the relation model of intentionality. After focusing on a specific kind of phenomenal intentionality theory—something I call modificationism—I examine three such accounts. From there I go on to discuss some common complaints/challenges these kinds of views face, and consider how they might be addressed within the modificationist framework. In Part 3, I address what I call the problem of cognitive contact: how do our contentful mental states manage to make cognitive contact with the ordinary objects (e.g. tables and chairs) that they appear to. The problem is particularly acute for any version of phenomenal intentionality that denies the relation view, and has been given very little attention in the literature. I consider how a modificationist might address this problem, and conclude that though some avenues appear promising, there is nevertheless a great deal of work to be done if modificationism, and phenomenal intentionality theory, is to overcome this problem.

Heuristics are often invoked in the philosophical, psychological, and cognitive science literatures to describe or explain methodological techniques or "shortcut" mental operations that help in inference, decision-making, and problem-solving. Yet there has been surprisingly little philosophical work done on the nature of heuristics and heuristic reasoning, and a close inspection of the way(s) in which "heuristic" is used throughout the literature reveals a vagueness and uncertainty with respect to what heuristics are and their role in cognition. This dissertation seeks to (...) remedy this situation by motivating philosophical inquiry into heuristics and heuristic reasoning, and then advancing a theory of how heuristics operate in cognition. I develop a positive working characterization of heuristics that is coherent and robust enough to account for a broad range of phenomena in reasoning and inference, and makes sense of empirical data in a systematic way. I then illustrate the work this characterization does by considering the sorts of problems that many philosophers believe heuristics solve, namely those resulting from the so-called frame problem. Considering the frame problem motivates the need to gain a better understanding of how heuristics work and the cognitive structures over which they operate. I develop a general theory of cognition which I argue underwrites the heuristic operations that concern this dissertation. I argue that heuristics operate over highly organized systems of knowledge, and I offer a cognitive architecture to accommodate this view. I then provide an account of the systems of knowledge that heuristics are supposed to operate over, in which I suggest that such systems of knowledge are concepts. The upshot, then, is that heuristics operate over concepts. I argue, however, that heuristics do not operate over conceptual content, but over metainformational relations between activated and primed concepts and their contents. Finally, to show that my thesis is empirically adequate, I consider empirical evidence on heuristic reasoning and argue that my account of heuristics explains the data. (shrink)

We argue that the presence of a word in an utterance serves as starting point for a relevance guided inferential process that results in the construction of a contextually appropriate sense. The linguistically encoded sense of a word does not serve as its default interpretation. The cases where the contextually appropriate sense happens to be identical to this linguistic sense have no particular theoretical significance. We explore some of the consequences of this view. One of these consequences is that there (...) may be many more mentally represented concepts than there are linguistically encoded concepts. (shrink)

This thesis is intended to analyze a mental phenomenon widely neglected in current philosophical discussions: personal memories. The first part presents a general framework to better understand what personal memories are, how we access our personal past and what we access about our personal past. Chapter 1 introduces traditional theories of memory: direct realism and representationalism in their different versions, as well as some objections. I defend here a particular form of representationalism that is based on the distinction between content, (...) intentional object and ontological object. Chapter 2 explores the possible contents of our personal memories, which prove to be heterogeneous, whereas chapter 3 analyses their possible intentional objects, with a special focus on past events. The second part of the thesis explores an aspect of our personal memories that was omitted in the first part: the senses in which our personal past is apprehended as personal. Chapter 4 examines the way in which the “self” intervenes in the construction of our personal memories. Chapters 5 and 6 focus on the analysis of what seems to be the most subjective aspect of our memories, that is, the emotions and feelings of our past experiences. In these last two chapters, I analyze the different interactions that can take place between memories and emotions and defend the idea that there can be emotional memories that are reducible neither to a propositional memory nor an occurrent and present emotion. The overall intention of this thesis is twofold. First, I aim to show to the philosophical community that there is still a lot to be said and discussed about memory as a mental phenomenon. And second, I intend to emphasize the importance of bringing into the philosophical discussions about the mind ideas coming from different philosophical traditions as well as ideas and empirical data coming from scientific research.

I develop and argue for a novel theory of the mental state of identity confusion. I also argue that this mental state can corrupt the proper function of singular terms in linguistic communication. Finally, I propose a theory according to which identity confusion should be treated as a the source of a new sort of linguistic performance error, similar to malapropism, slips of the tongue, and so-called intentional obfuscation (inducing false belief by manipulating language in specific ways). -/- Going into (...) a bit more detail, I start by arguing that contemporary analytic philosophy, and philosophy of language in particular, has been dominated by a ‘puzzle-driven’ methodology. This tradition, I claim, seeks to provide a coherent system for describing semantic features of all conceivable cases where a speaker is confused about the identity or distinctness of an object. On my view, identity confusion is a mental state of an agent who either believes falsely that a is identical to b or believes falsely that a is not identical to b. I show how many influential arguments in philosophy – e.g., Kripke on semantic reference and speaker’s reference – are invalidated because of false assumptions about the state of identity confusion. -/- More positively, I assume an ‘explanation-driven’ approach, combining strands in Gricean intentionalism and Ruth Millikan’s teleosemantics. On this view, confused speakers are ‘sub-optimal’: their mental state disrupts the proper function of the relevant singular terms in their idiolects. Furthermore, I flesh out a theoretically fruitful notion of ‘edenic reference,’ which idealizes away from confusion in defining the optimal or stabilizing function of singular terms. I argue that speakers must satisfy certain broadly cognitive constraints if their utterances are to play a role in explaining the maintenance of a practice of using a singular term in a linguistic community.

This paper aims to provide a mathematically tractable background against which to model both modal cognitivism and modal expressivism. I argue that epistemic modal algebras comprise a materially adequate fragment of the language of thought, and endeavor to show how such algebras provide the resources necessary to resolve Russell's paradox of propositions. I demonstrate, then, how modal expressivism can be regimented by modal coalgebraic automata, to which the above epistemic modal algebras are dually isomorphic. I examine, in particular, the virtues (...) unique to the modal expressivist approach here proffered in the setting of the foundations of mathematics, by contrast to competing approaches based upon both the inferentialist approach to concept-individuation and the codification of speech acts via intensional semantics.

This paper examines the interaction between the philosophy and psychology of concepts and the modal characterization of the deductive concept of logical validity. The concept of logical consequence on which I focus is model-theoretic, where the concept records the property of necessary truth-preservation from the premise of an argument to its conclusion, as well as the condition that, in the class of all possible worlds in which a premise is true, a consequent formula or succedent class of formulas is true, (...) as well. Focusing on the case of logical necessity, I argue that the ability to account for the modal properties of concepts places a desideratum on the explanatory adequacy of theories of mental representation. I outline, then, five approaches to the nature of concepts pursued in philosophy and cognitive science, and argue that the above desideratum does not appear to be satisfiable by the candidate proposals. Given the limits of the foregoing, I appeal to a sixth approach -- namely, cognitivism about epistemic modality, according to which epistemic intensions are semantically imbued functions in the language of thought -- and endeavor to demonstrate how the proposal can sufficiently account for the modal profile of the concept of logical consequence. (shrink)

This paper aims to vindicate the thesis that cognitive computational properties are abstract objects implemented in physical systems. I avail of the equivalence relations countenanced in Homotopy Type Theory, in order to specify an abstraction principle for epistemic intensions. The homotopic abstraction principle for epistemic intensions provides an epistemic conduit into our knowledge of intensions as abstract objects. I examine, then, how intensional functions in Epistemic Modal Algebra are deployed as core models in the philosophy of mind, Bayesian perceptual psychology, (...) and the program of natural language semantics in linguistics, and I argue that this provides abductive support for the truth of homotopic abstraction. Epistemic modality can thus be shown to be both a compelling and a materially adequate candidate for the fundamental structure of mental representational states, comprising a fragment of the Language of Thought.

Objections to AI and computational cognitive science are myriad. Accordingly, there are many different reasons for these attacks. But all of them come down to one simple observation: humans seem a lot smarter that computers -- not just smarter as in Einstein was smarter than I, or I am smarter than a chimpanzee, but more like I am smarter than a pencil sharpener. To many, computation seems like the wrong paradigm for studying the mind. (Actually, I think there are deeper (...) and darker reasons why AI, especially, is so often the brunt of polemics, see Dietrich, 2000.) But the truth is this: AI is making exciting progress, and will one day make a robot as intelligent as a person; indeed the robot will be conscious. And all this is because of another truth: the computational paradigm is the best thing to come down the pike since the wheel. (shrink)

Ken Safir, Rutgers University ABSTRACT: It is argued that the indexicality of first person pronouns is arises from a restriction on the pronouns themselves, as opposed to any operator that binds them. The nature of this restriction is an asyntactic constant function that picks out individuals to the context of utterance (following Kaplan, 1989)). Constant function pronouns do not require an antecedent, neither an operator nor an argument, although this does not prevent them from participating in bound readings if an (...) appropriate antecedent is introduced. The notion that agents of contexts and agents of propositional attitudes are versions of the same operator-variable relation is thus rejected, along with certain less fine-grained versions of the nature of de se interpretation. Consequently, indexical pronouns such as first person ones contrast with logophoric pronouns, which are necessarily operator-bound by perspectival operators introduced by propositional attitude verbs. Scope-sensitive properties of operator-binding and the perspectival interpretations that are imposed on logophoricity distinguish the latter from constant function phenomena, which are sensitive neither to scope, as it is usually treated, nor perspectival shifts. Constant function phenomena are also detectable as restrictions on third person forms, and two such examples are lightly explored: the English generic pronoun one and the proximate/obviative distinction in languages like Fox.

Is Language the Ultimate Artefact? (henceforth ILUA) was originally published alongside a paper by Andy Clark called Is Language Special? Some remarks on control, coding, and co-ordination (Clark 2004). One concern (among others) of the latter paper was to resist the argument of the former. In this short afterword, I shall attempt a counterresponse to Clark’s resistance. In so doing I hope to reveal, in a new and perhaps clearer way, what the most important issues really are in this (still (...) unresolved) debate. (shrink)

Part I Introduction The specific problem adressed in this thesis is: what is the rational use of theory and experiment in the process of scientific discovery, in theory and in the practice of drug research for Parkinson’s disease? The thesis aims to answer the following specific questions: what is: 1) the structure of a theory?; 2) the process of scientific reasoning?; 3) the route between theory and experiment? In the first part I further discuss issues about rationality in science as (...) introduction to part II, and I present an overview of my case-study of neuropharmacology, for which I interviewed researchers from the Groningen Pharmacy Department, as an introduction to part III. Part II Discovery In this part I discuss three theoretical models of scientific discovery according to studies in the fields of Logic, Cognition, and Computation. In those fields the structure of a theory is respectively explicated as: a set of sentences; a set of associated memory chunks; and as a computer program that can generate the observed data. Rationality in discovery is characterized by: finding axioms that imply observation sentences; heuristic search for a hypothesis, as part of problem solving, by applying memory chunks and production rules that represent skill; and finding the shortest program that generates the data, respectively. I further argue that reasoning in discovery includes logical fallacies, which are neccesary to introduce new hypotheses. I also argue that, while human subjects often make errors in hypothesis evaluation tasks from a logical perspective, these evaluations are rational given a probabilistic interpretation. Part III Neuropharmacology In this last part I discusses my case-study and a model of discovery in a practice of drug research for Parkinson’s disease. I discuss the dopamine theory of Parkinson’s disease and model its structure as a qualitative differential equation. Then I discuss the use and reasons for particular experiments to both test a drug and explore the function of the brain. I describe different kinds of problems in drug research leading to a discovery. Based on that description I distinguish three kinds of reasoning tasks in discovery, inference to: the best explanation, the best prediction and the best intervention. I further demonstrate how a part of reasoning in neuropharmacology can be computationally modeled as qualitative reasoning, and aided by a computer supported discovery system. (shrink)
