Che cosa vuol dire per le espressioni del nostro linguaggio avere un significato? Secondo un approccio oggi sostanzialmente standard in semantica, avere significato vuol dire prima di tutto avere un contenuto rappresentazionale, cioè poter rappresentare qualcosa. Secondo un inferenzialista come Robert Brandom, invece, le espressioni del nostro linguaggio hanno contenuto perché sono inserite in una rete di relazioni inferenziali, rispetto alla quale possono essere utilizzate per dare e richiedere ragioni. Il libro di Pietro Salis, Pratiche discorsive razionali, presenta e discute (...) alcuni degli aspetti più interessanti dell'inferenzialismo normativo di Brandom. Si tratta della seconda monografia in lingua italiana dedicata alla filosofia del linguaggio brandomiana dopo quella di Giovagnoli (2004). Per trovare elementi di paragone con il lavoro di Salis occorre allora guardare alle pubblicazioni in lingua inglese. Tra queste ci sono le raccolte di saggi curate da Stekeler-Weithofer (2008), Prien e Schweikard (2008), e Weiss e Wanderer (2010). Ma anche le introduzioni monografiche di Wanderer (2008) e Turbanti (2017). La prima di queste introduzioni, in particolare, è quella più simile al libro di Salis, soprattutto dal punto di vista tematico. (shrink)

In this reply to James H. Fetzer’s “Minds and Machines: Limits to Simulations of Thought and Action”, I argue that computationalism should not be the view that (human) cognition is computation, but that it should be the view that cognition (simpliciter) is computable. It follows that computationalism can be true even if (human) cognition is not the result of computations in the brain. I also argue that, if semiotic systems are systems that interpret signs, then both humans and computers are (...) semiotic systems. Finally, I suggest that minds can be considered as virtual machines implemented in certain semiotic systems, primarily the brain, but also AI computers. In doing so, I take issue with Fetzer’s arguments to the contrary. (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.

Relationship between default semantics and modularity of mind (in particular mind reading through the principle of Relevance).

This dissertation is devoted to dual-process theories, widely discussed in the recent literature in cognitive science. The author argues for a significantly modified version of the account suggested by Samuels (2009), replacing the distinction between ‘Systems’ with a distinction between ‘Types of processes,’ which allows a critique of both the (only) modularist accounts and the accounts describing a deep difference between two systems each having their specificities (functional, phenomenological and neurological). In the account of dual-process theories developed here, the distinction (...) between ‘Types of processes’ is considered, a priori, only as a heuristic distinction allowing to better understand the mind and to explain some of its properties. The main idea defended in this dissertation is that cognitive processes should be distinguished by their position in a multidimensional conceptual space allowing researchers to consider all of the characteristics and peculiarities attributed to a process, which is preferable to accounts forcing the process into either ‘System’ or either ‘Type’ identified in the most influential approaches (cf. Evans, 2008). Once this research program is in place, it will become possible to revise the concepts used and the categories defined to ground anew some of the notions we find in the literature (‘module,’ ‘System 1 / 2,’ etc.). The argument is made in three steps: -/- 1) The first chapter aims at a clarification of the notion of ‘module’ commonly used in cognitive science. Against the accounts aiming at a weakening of the notion in order to classify all of the mind’s processes as modular, the author – following most notably Faucher and Poirier (2009) and Samuels (2006) – casts doubt on how this notion is used by many influential authors, particularly in evolutionary psychology (e.g. Barrett, Carruthers, Cosmides, Tooby). -/- 2) The objective of the second chapter is to present, examine and criticize many dual-process theories and to suggest that no theory currently discussed is adequate to describe the architecture of mind. The accounts, especially influent or representative, suggested by Stanovich (1999; 2004; 2009), by Evans (2008; 2009), by Lieberman (2007; 2009) and by Carruthers (2006; 2009), are examined. -/- 3) In the third chapter, the author criticizes the framework developed by Samuels (2009) before developing his own account of dual-process theories and discussing some of its advantages.

Over the last three decades, the application of evolutionary theory to the human sciences has shown remarkable growth. This growth has also been characterised by a ‘splitting’ process, with the emergence of distinct sub-disciplines, most notably: Human Behavioural Ecology (HBE), Evolutionary Psychology (EP) and studies of Cultural Evolution (CE). Multiple applications of evolutionary ideas to the human sciences are undoubtedly a good thing, demonstrating the usefulness of this approach to human affairs. Nevertheless, this fracture has been associated with considerable tension, (...) a lack of integration, and sometimes outright conflict between researchers. In recent years however, there have been clear signs of hope that a synthesis of the human evolutionary behavioural sciences is underway. Here, we briefly review the history of the debate, both its theoretical and practical causes; then provide evidence that the field is currently becoming more integrated, as the traditional boundaries between sub-disciplines become blurred. This article constitutes the first paper under the new editorship of the Journal of Evolutionary Psychology, which aims to further this integration by explicitly providing a forum for integrated work.

People cannot contemplate a proposition without believing that proposition. A model of belief fixation is sketched and used to explain hitherto disparate, recalcitrant, and somewhat mysterious psychological phenomena and philosophical paradoxes. Toward this end I also contend that our intuitive understanding of the workings of introspection is mistaken. In particular, I argue that propositional attitudes are beyond the grasp of our introspective capacities. We learn about our beliefs from observing our behavior, not from introspecting our stock beliefs. -/- The model (...) of belief fixation offered in the dissertation poses a novel dilemma for theories of rationality. One might have thought that the ability to contemplate ideas while withholding assent is a necessary condition on rationality. In short, it seems that rational creatures shouldn‘t just form their beliefs based on whatever they happen to think. However, it seems that we are creatures that automatically and reflexively form our beliefs based on whatever propositions we happen to consider. Thus, either the rational requirement that states that we must have evidence for our beliefs must be jettisoned or we must accept the conclusion that we are necessarily irrational. (shrink)

The 20 sup > th /sup > century has been a tumultuous time in psychology -- a century in which the discipline struggled with basic questions about its intellectual identity, but nonetheless managed to achieve spectacular growth and maturation. It’s not surprising, then, that psychology has attracted sustained philosophical attention and stimulated rich philosophical debate. Some of this debate was aimed at understanding, and sometimes criticizing, the assumptions, concepts and explanatory strategies prevailing in the psychology of the time. But much (...) philosophical work has also been devoted to exploring the implications of psychological findings and theories for broader philosophical questions like: Are humans really rational animals? How malleable is human nature? and Do we have any innate knowledge or innate ideas? One particularly noteworthy fact about philosophy of psychology in the 20 sup > th /sup > century is that, in the last quarter of the century, the distinction between psychology and the philosophy of psychology began to dissolve as philosophers played an increasingly active role in articulating and testing empirical theories about the mind and psychologists became increasingly interested in the philosophical underpinnings and implications of their work. Our survey is divided into five sections, each focusing on an important theme in 20 sup > th /sup > century psychology which has been the focus of philosophical attention and has benefited from philosophical scrutiny.

Review article, based on ‘Brain Story’, by Susan Greenfield.

This PhD thesis focuses on the philosophical foundations of Neuroeconomics, an innovative research program which combines findings and modelling tools from economics, psychology and neuroscience to account for human choice behaviour. The proponents of Neuroeconomics often manifest the ambition to foster radical modifications in the accounts of choice behaviour developed by its parent disciplines. This enquiry provides a philosophically informed appraisal of the potential for success and the relevance of neuroeconomic research for economics. My central claim is that neuroeconomists can (...) help other economists to build more predictive and explanatory models, yet are unlikely to foster revolutionary modifications in the economic theory of choice. The contents are organized as follows. In chapters 1-2, I present neuroeconomists’ investigative tools, distinguish the most influential approaches to neuroeconomic research and reconstruct the case in favour of a neural enrichment of economic theory. In chapters 3-7, I combine insights from neuro-psychology, economic methodology and philosophy of science to develop a systematic critique of Neuroeconomics. In particular, I articulate four lines of argument to demonstrate that economists are provisionally justified in retaining a methodologically distinctive approach to the modelling of decision making. My first argument points to several evidential and epistemological concerns which complicate the interpretation of neural data and cast doubt on the inferences neuroeconomists often make in their studies. My second argument aims to show that the trade-offs between the modelling desiderata that neuroeconomists and other economists respectively value severely constrain the incorporation of neural insights into economic models. My third argument questions neuroeconomists’ attempts to develop a unified theory of choice behaviour by identifying some central issues on which they hold contrasting positions. My fourth argument differentiates various senses of the term ‘revolution’ and illustrates that neuroeconomists are unlikely to provide revolutionary contributions to economic theory in any of these senses.

Evolutionary explanations of psychological phenomena have become widespread. This paper examines a recent attempt by Nichols and Grantham (2000) to circumvent the problem of epiphenomenalism in establishing the selective status of consciousness. Nichols and Grantham (2000) argue that a case can be made for the view that consciousness is an adaptation based on its complexity. I set out this argument and argue that it fails to establish that phenomenal consciousness is a complex system. It is suggested that the goal of (...) establishing consciousness as an adaptation may be better served by rejecting the distinction between access consciousness and phenomenal consciousness.

This thesis aims to develop a psychologically plausible account of concepts by integrating key insights from philosophy (on the metaphysical basis for concept possession) and psychology (on the mechanisms underlying concept acquisition). I adopt an approach known as informational atomism, developed by Jerry Fodor. Informational atomism is the conjunction of two theses: (i) informational semantics, according to which conceptual content is constituted exhaustively by nomological mind–world relations; and (ii) conceptual atomism, according to which (lexical) concepts have no internal structure. I (...) argue that informational semantics needs to be supplemented by allowing content-constitutive rules of inference (“meaning postulates”). This is because the content of one important class of concepts, the logical terms, is not plausibly informational. And since, it is argued, no principled distinction can be drawn between logical concepts and the rest, the problem that this raises is a general one. An immediate difficulty is that Quine’s classic arguments against the analytic/synthetic distinction suggest that there can be no principled basis for distinguishing content-constitutive rules from the rest. I show that this concern can be overcome by taking a psychological approach: there is a fact of the matter as to whether or not a particular inference is governed by a mentally-represented inference rule, albeit one that analytic philosophy does not have the resources to determine. I then consider the implications of this approach for concept acquisition. One mechanism underlying concept acquisition is the development of perceptual detectors for the objects that we encounter. I investigate how this might work, by drawing on recent ideas in ethology on ‘learning instincts’, and recent insights into the neurological basis for perceptual learning. What emerges is a view of concept acquisition as involving a complex interplay between innate constraints and environmental input. This supports Fodor’s recent move away from radical concept nativism: concept acquisition requires innate mechanisms, but does not require that concepts themselves be innate. (shrink)

Hubert Dreyfus has argued recently that the frame problem, discussion of which has fallen out of favour in the AI community, is still a deal breaker for the majority of AI projects, despite the fact that the logical version of it has been solved. (Shanahan 1997, Thielscher 1998). Dreyfus thinks that the frame problem will disappear only once we abandon the Cartesian foundations from which it stems and adopt, instead, a thoroughly Heideggerian model of cognition, in particular one that does (...) not appeal to representations. I argue that Dreyfus is too hasty in his condemnation of all representational views; the argument he provides licenses only a rejection of disembodied models of cognition. In casting his net too broadly, Dreyfus circumscribes the cognitive playing field so closely that one is left wondering how his Heideggerian alternative could ever provide a foundation explanatorily robust enough for a theory of cognition. As a consequence, he dilutes the force of his legitimate conclusion, that disembodied cognitive models will not work, and this conclusion needs to be heard. By disentangling the ideas of embodiment and representation, at least with respect to Dreyfus‘ frame problem argument, the real locus of the general polemic between traditional computational/representational cognitive science and the more recent embodied approaches is revealed. From this, I hope that productive debate will ensue. (shrink)

The Hippocratic Oath is a code of ethics defining correct behaviour by physicians they are required to commit themselves to before being accepted into the profession. It was the first code of ethics for any profession. While originating in Ancient Greece, it subsequently evolved, but the current code still embodies many of the core injunctions of the original code. The most widely accepted current form is the 2006 The Declaration of Geneva by the World Medical Association to be taken before (...) being admitted as a member of the medical profession. The most important of its injunctions are: ‘The health of my patient will be my first consideration’ and ‘I will maintain the utmost respect for human life’. The first is a rewording of the injunction from Epidemics, Book I, of the Hippocratic school: ‘Practice two things in your dealings with disease: either help or do not harm the patient.’ This was later simplified to the most basic precept of the Hippocratic Oath: ‘First, do no harm.’ It is one of the principal precepts of bioethics that all students in healthcare that, given an existing problem, it may be better not to do something, or even to do nothing, than to risk causing more harm than good. The development of neurotechnology could be subsumed with little modification under the Geneva formulation of the Hippocratic Oath, extending this precept to a commitment not to damage people’s psychological health.

This thesis contributes to a better conceptual understanding of how self-organized control works. I begin by analyzing the control problem and its solution space. I argue that the two prominent solutions offered by classical cognitive science (centralized control with rich commands, e.g., the Fodorian central systems) and embodied cognitive science (distributed control with simple commands, such as the subsumption architecture by Rodney Brooks) are merely two positions in a two-dimensional solution space. I outline two alternative positions: one is distributed control (...) with rich commands, defended by proponents of massive modularity hypothesis; the other is centralized control with simple commands. My goal is to develop a hybrid account that combines aspects of the second alternative position and that of the embodied cognitive science (i.e., centralized and distributed controls with simple commands). Before developing my account, I discuss the virtues and challenges of the first three. This discussion results in a set of criteria for successful neural control mechanisms. Then, I develop my account through analyzing neuroscientific models of decision-making and control with the theoretical lenses provided by formal decision and social choice theories. I contend that neural processes can be productively modeled as a collective of agents, and neural self-organization is analogous to democratic self-governance. In particular, I show that the basal ganglia, a set of subcortical structures, contribute to the production of coherent and intelligent behaviors through implementing “democratic" procedures. Unlike the Fodorian central system—which is a micro-managing “neural commander-in-chief”—the basal ganglia are a “central election commission.” They delegate control of habitual behaviors to other distributed control mechanisms. Yet, when novel problems arise, they engage and determine the result on the basis of simple information (the votes) from across the system with the principles of neurodemocracy, and control with simple commands of inhibition and disinhibition. By actively managing and taking advantage of the wisdom-of-the-crowd effect, these democratic processes enhance the intelligence and coherence of the mind’s final "collective" decisions. I end by defending this account from both philosophical and empirical criticisms and showing that it meets the criteria for successful solution. (shrink)

La plupart des auteur-es ayant abordé le problème de l'extension du cognitif, tel qu'il a émergé des débats autour de la thèse de l'esprit étendu, ont supposé que cette extension devait prendre la forme d'un espace régulier, qui peut être ceint par des frontières. Cependant, la littérature en question ne traite pas explicitement de cette supposition, de sorte que, malgré son influence, il n'y a pas d'évaluation de sa véracité ou de sa légitimité. Dans ce mémoire, cette hypothèse est remise (...) en question, et nous prenons sa contrepartie pour hypothèse de recherche, à savoir que, malgré l'assurance des auteur-es qui l'épousent, il est tout à fait légitime d'explorer des propositions de caractérisation du cognitif qui aboutissent à d'autres formes d'extension. Pour démontrer notre hypothèse (H1), nous posons deux autres hypothèses : (H2) les auteur-es qui épousent la supposition selon laquelle l'esprit doit s'étendre sur un espace ceint par des frontières le font sur la base de l'intuition individualiste, et (H3) l'intuition individualiste, malgré certaines apparences, ne permet pas de justifier cette supposition. Nous démontrons H2 à l'aide d'une analyse de texte faite sur le corpus des auteur-es ayant abordé la question de l'extension du cognitif dans la foulée des débats sur l'esprit étendu, et nous montrons que la littérature en sciences cognitives et en philosophie de l'esprit nous donne des raisons de croire que H3 est vraie.

Recent trends in Cognitive Ethics have emphasized the conceptual debts with the development of the Science of Human Nature in the late 1600s and early 1700s.

The essay is a critical review of three possible approaches in the theory of knowledge while tracing the biological roots of knowledge: empiricist, rationalist and developmentalist approaches. Piaget's genetic epistemology, a developmentalist approach, is one of the first comprehensive treatments on the question of tracing biological roots of knowledge. This developmental approach is currently opposed, without questioning the biological roots of knowledge, by the more popular rationalist approach, championed by Chomsky. Developmental approaches are generally coherent with cybernetic models, of which (...) the theory of autopoiesis proposed by Maturana and Varela made a significant theoretical move in proposing an intimate connection between metabolism and knowledge. Modular architecture is currently considered more or less an undisputable model for both biology as well as cognitive science. By suggesting that modulation of modules is possible by motor coordination, a proposal is made to account for higher forms of conscious cognition within the four distinguishable layers of the human mind. Towards the end, the problem of life and cognition is discussed in the context of the evolution of complex cognitive systems, suggesting the unique access of phylogeny during the ontogeny of human beings as a very special case, and how the problem cannot be dealt with independent of the evolution of coding systems in nature.

ABSTRACT: The Reflexive Theory of Perception (RTP) claims that perception of an object or property X by an organism Z consists in Z being caused by X to acquire some disposition D toward X itself. This broadly behavioral perceptual theory explains perceptual intentionality and correct versus incorrect, plus successful versus unsuccessful, perception in a plausible evolutionary framework. The theory also undermines cognitive and perceptual modularity assumptions, including informational or purely epistemic views of perception in that, according to the RTP, any (...) X-caused and X-directed dispositions are genuinely perceptual—including affective, attitudinal, and immediately activated purely action-directed behavioral dispositions. Thus the RTP has the potential to provide the foundations for a broadly behavioral counter-revolution in cognitive science. (shrink)

Viime vuosina ihmistieteiden kentässä on saanut osakseen paljon huomiota uusi lähestymistapa, jota kutsutaan ”evoluutiopsykologiaksi”. Sen piiristä on esimerkiksi väitetty, että evoluutio on muokannut meidän parinvalintamieltymyksiämme niin, että miehillä on taipumus tuntea vetoa lisääntymiskykyisiltä näyttäviin nuoriin naisiin, pyrkiä parittelemaan aina tilaisuuden tullen mahdollisimman monien naisten kanssa ja olla mustasukkaisia, kun taas naiset ovat taipuvaisia mieltymään iäkkäämpiin miehiin, joilla on valtaa ja resursseja. Luonnonvalinnalla on pyritty myös selittämään mm. raiskauksia.

My dissertation establishes the basis for a systematic outlook on the role language plays in human cognition. It is an investigation based on a cognitive conception of language, as opposed to communicative conceptions, viz. those that suppose that language plays no role in cognition. I focus, in Chapter 2, on three paradigmatic theories adopting this perspective, each offering different views on how language contributes to or changes cognition. -/- In Chapter 3, I criticize current views held by dual-process theorists, and (...) I develop a picture of the complex interaction between language and cognition that I deem more plausible by using resources from the literature on the evolution of the faculty of language. Rather than trying to find one general explanation for all cognitive processes, I take seriously the idea that our mind is composed of many subsystems, and that language can interact and modify each in different ways. There is no reason offered in the empirical literature—besides maybe parsimony—that suggest that language has to interact in the same ways with all cognitive processes. Yet, this is seemingly taken for granted, especially within dual-process approaches. -/- On my view, it is a central requirement for a theory of the role of language in cognition to explain how language might have effects, at once, on and within various parts of cognition. In Chapter 4, I explore how this framework can modify how we think about some experiments in psychology, specifically in research on categorization. My idea is that language, once it evolved, changed how some cognitive capacities worked and interacted with each other, but did so in more than one or two ways. Cognitive systems are changed in very different ways—sometimes the transformation is very subtle, such as our way of forming categories by using how similar objects are, while other times it is deep and changes the very way the system works.

Este artículo investiga la coherencia entre la propuesta de una organización modular masiva de la mente y el enfoque de las heurísticas simples. Se discute una serie de potenciales conflictos entre los dos programas, pero finalmente son desestimados. De todos modos, el programa de las heurísticas simples sí termina socavando uno de los muchos argumentos propuestos para apoyar la modularidad masiva, al menos en el modo en que esta última es comprendida por los filósofos. Así que un resultado de la (...) argumentación será forzarnos a reexaminar la mejor manera de caracterizar la noción de modularidad en la ciencia cognitiva, para que la tesis de la modularidad masiva no deba ser abandonada completamente. Lo que está en juego en esta discusión es si existe una noción de "módulo" que esté bien motivada, de modo que tengamos una buena razón para pensar que la mente humana deba ser masivamente modular en su organización. Argumentaré que tal noción existe. This chapter investigates the extent to which claims of massive modular organization of the mind are consistent with the main elements of the simple heuristics research program. A number of potential sources of conflict between the two programs are investigated and defused. However, the simple heuristics program turns out to undermine one of the main arguments offered in support of massive modularity, at least as the latter is generally understood by philosophers. So one result of the argument will be to force us to re-examine the way in which the notion of modularity in cognitive science should best be characterized, if the thesis of massive modularity isn't to be abandoned altogether. What is at stake in this discussion, is whether there is a well-motivated notion of "module" such that we have good reason to think that the human mind must be massively modular in its organization. I shall be arguing that there is. (shrink)

En las ciencias cognoscitivas, existe una teoría con respecto a la arquitectura computacional de la mente conocida como el modularismo masivo. Esta teoría sostiene que la mente está en su mayoría constituida por mecanismos que son cognoscitivamente modulares. Algunos de los defensores de esta teoría proponen un argumento cuya conclusión es que es muy probable que mecanismos que son cognoscitivamente muy modulares sean más evolucionables que aquellos mecanismos que no son cognoscitivamente modulares. Aquí muestro que para poder defender plausiblemente esta (...) conclusión es necesario añadir a la noción de modularidad cognoscitiva la siguiente característica: "Un sistema cognoscitivo S de organismos de una población P es cognoscitivamente modular sólo si S es variacionalmente modular en P." Defiendo también la idea que una de las características que normalmente se asocian al concepto de modularidad cognoscitiva-i.e., la noción de doble disociación cognoscitiva-es muy cercana a la idea de modularidad variacional. Adicionalmente, argumento que no hay razones positivas, y sí algunas razones negativas, para pensar que las otras características usualmente asociadas al concepto de modularidad cognoscitiva-tales como la especificidad de dominio o la especialización funcional-coadyuven a la evolucionabilidad de los módulos cognoscitivos. In the cognitive sciences, there is a theory concerning the computational architecture of the mind known as massive modularity. This theory holds that the mind is constituted mostly by cognitive modules. Some of the defenders of this theory have put forward an argument whose conclusion is that it is very likely that those mechanisms that are cognitively very modular are more evolvable than mechanisms that are not cognitively modular. Here I show that a plausible defense of this conclusion requires us to add to the usual notion of cognitive modularity the following characteristic: "A cognitive system S of organism of a population P is cognitively modular only if S is variationally modular in P." I also defend the view that one of the characteristics normally associated to the concept of cognitive modularity-namely, the notion of a double dissociation-is conceptually close to the concept of variational modularity. Additionally, I argue that there are not positive reasons-while there are some negative ones-to think that the other characteristics usually associated to cognitive modularity, such as domain specificity or functional specialization, enhance the evolvability of cognitive modules.

Philosophers and cognitive scientists of perception by custom have investigated individual sense modalities in relative isolation from each other. However, perceiving is, in a number of respects, multimodal. The traditional sense modalities should not be treated as explanatorily independent. Attention to the multimodal aspects of perception challenges common assumptions about the content and phenomenology of perception, and about the individuation and psychological nature of sense modalities. Multimodal perception thus presents a valuable opportunity for a case study in mature interdisciplinary cognitive (...) science. This chapter aims to raise these issues against the background of unimodal approaches in the study of perception. It presents some of the central empirical findings concerning multimodality, and it explains the philosophical implications of these findings. Foremost, it aims to encourage and open avenues for future research. (shrink)

Evolutionary psychology claims biological inclinations for certain behaviors (e.g., a desire for more frequent sex and more sexual partners by males as compared to females), and the origin of these inclinations in natural selection. Jerry Fodor’s recent book, The Mind Doesn’t Work that Way (2000), grants the nativist case for such biological grounding but disputes the presumed certainty of its origin in natural selection. Nevertheless, there is today a consensus that at least some of the claims of evolutionary psychology are (...) true, and their broad appeal suggests that many see them as easy insights into and possible license for some controversial behaviors. Evolutionary psychologists, on the other hand, caution that an origin in natural selection implies only an inclination for certain behaviors, and not that the behaviors will be true of all people, will lead to happiness or are morally correct. But such cautions can be as facile as the simplistic positions they are intended to counter. A biological basis implies tendencies to behaviors that will be pleasurable when engaged in, and that can be modified to an extent and at a psychic cost that is, at best, not fully understood. Also, while it is true that naturally selected behaviors are not necessarily moral, the implications of current evolutionary psychology cast doubt on any absolute foundation for morality at all, as well as suggesting limits on our ability to fully understand both ourselves and the universe around us. However, this does not mean that our (relative) values or apparent free will are any less real or important for us. (shrink)

The objectives of this article are twofold. First, by denying the dualism inherent in attempts to load metaphysical significance on the inner/outer distinction, it defends the view that scientific investigation can approach consciousness in itself, and is not somehow restricted in scope to the outward manifestations of a private and hidden realm. Second, it provisionally endorses the central tenets of global workspace theory, and recommends them as a possible basis for the sort of scientific understanding of consciousness thus legitimised. However, (...) the article goes on to argue that global workspace theory alone does not constitute a fully worked-out objective account of the conscious subject. This requires additional attention to be paid to the issue of embodiment, and to the possibility of indexicality that arises when an instantiation of the global workspace architecture inhabits a spatially localised body.

Conciliatory theories of disagreement face a revenge problem; they cannot be coherently believed by one who thinks they have peers who are not conciliationists. I argue that this is a deep problem for conciliationism.

The aim of this dissertation is to create a naturalistic philosophical picture of creative capacities that are specific to our species, focusing on artistic ability, religious reflection, and scientific study. By integrating data from diverse domains within a philosophical anthropological framework, I have presented a cognitive and evolutionary approach to the question of why humans, but not other animals engage in such activities. Through an application of cognitive and evolutionary perspectives to the study of these behaviors, I have sought to (...) provide a more solid footing for philosophical anthropological discussions of uniquely human behavior. In particular, I have argued that art, religion and science, which are usually seen as achievements that are quite remote from ordinary modes of reasoning, are subserved by evolved cognitive processes that serve functions in everyday cognitive tasks, that arise early and spontaneously in cognitive development, that are shared cross-culturally, and that have evolved in response to selective pressures in our ancestral past. These mundane cognitive processes provide a measuring rod with which we can assess a diversity of cultural phenomena; they form a unified explanatory framework to approach human culture. I have argued that we can explain uncommon thoughts in terms of interactions between common minds. This dissertation is subdivided into four parts. Part I outlines the problem of human uniqueness, examining theories on how humans conceptualize the world, and what their mental tool box looks like. Part II discusses the evolutionary and cognitive origins of human artistic behavior. Part III focuses on the cognitive science of religion, especially on how it can be applied to the reasoning of theologians and philosophers of religion. Part IV considers the cognitive basis of scientific practice. (shrink)

This thesis is an empirical and theoretical exploration of the surprising finding that people often may fail to notice dramatic mismatches between what they want and what they get, a phenomenon my collaborators and I have named choice blindness. The thesis consists of four co-authored papers, dealing with different aspects of the phenomenon. Paper one presents an initial set of studies using a computerised choice procedure, and discusses the relation of choice blindness to the parent phenomenon of change blindness. Paper (...) two is the most central paper of the thesis. In this study, participants were shown pairs of pictures of female faces, and were instructed to choose which face in each pair they found most attractive. In addition, on some trials, immediately after their choice, they were asked to verbally describe the reasons for choosing the way they did. Unknown to the participants, on certain trials, a double-card ploy was used to covertly exchange one face for the other. On these trials, the outcome of the choice became the opposite of what they intended. Counting across all conditions of the experiment no more than a fourth of all such manipulated trials were detected. But not only were the participants in the experiment blind to the manipulation of their choices, they also offered introspectively derived reasons for preferring the alternative they were given instead. A second major conclusion of this paper is that normal participants may produce confabulatory reports when asked to describe the reasons behind their choices. Paper three applies this form of analysis of introspection and confabulation to a second corpus of reports collected within the choice blindness paradigm. In this paper we use word-frequency and latent semantic analysis to contrast the introspective reasons given in non-manipulated and manipulated trials, but very few differences between these two groups of reports were found. In paper four, passer-by shoppers in a local supermarket were invited to sample two different varieties of jam and tea, and to decide which alternative in each pair they preferred the most. After their choice, the participants were asked to again sample to chosen alternative and describe why that one was preferred. At this point, the content of the sample containers were secretly switched, so that the outcome of the choice became the opposite of what the participants intended. No more than a third of the manipulated trials were detected, thus demonstrating considerable levels of choice blindness for the taste and smell of two different consumer goods. (shrink)

This paper explores the relationship between several ideas about the mind and cognition. The hypothesis of extended cognition claims that cognitive processes can and do extend outside the head, that elements of the world around us can actually become parts of our cognitive systems. It has recently been suggested that the hypothesis of extended cognition is entailed by one of the foremost philosophical positions on the nature of the mind: functionalism, the thesis that mental states are defined by their functional (...) relations rather than by their physical constituents. Furthermore, it has been claimed that functionalism entails a version of extended cognition which is sufficiently radical as to be obviously false. I survey the debate and propose several ways of avoiding this conclusion, emphasizing the importance of distinguishing the hypothesis of extended cognition from the related notion of the extended mind.

Evolutionary psychology often does not sufficiently document the innate constraint and domain specificity required for strong adaptationist argument. We develop these criteria within the domain of music. First, we advocate combining computational, developmental, cross-cultural, and neuroscience research to address the ways in which a domain is innately constrained. Candidate constraints in music include the importance of the octave and other simple pitch ratios, the categorization of the octave into tones, the importance of melodic contour, tonal hierarchies, and principles of grouping (...) and meter. Second, we advocate combining psychological, neuroscience, and genetic research across cognitive domains to address the domain specificity of such constraints. Currently available evidence suggests that the innate constraints in music are not specific to that domain, making it unclear which domain(s) provided the relevant selection pressures. (shrink)

The Cognitive Science era can be divided into two distinct periods with respect to the topic of innateness, at least from the viewpoint of the linguist. The first period, which began in the late 1950s and was characterized by the work of people like Chomsky and Fodor, argued for reviving a nativist position, in which a substantial amount of people’s knowledge of language was innate rather than learned by association or induction or analogy. This constituted a break with the empiricist/behaviorist/structuralist (...) tradition that had dominated the field before that. (shrink)

In the Philosophy of Cognitive Science, it is a common held view that the modularity hypothesis for cognitive mechanisms and the innateness hypothesis for mental contents are conceptually independent. In this paper I distinguish between substantial and deflationist modularity as well as between substantial and deflationist innatism, and I analyze whether the conceptual independence between substantial modularity and innatism holds. My conclusion will be that if what is taken into account are the essential properties of the substantial modules, i.e. domain (...) specificity and informational encapsulation, then it seems to be such independence. However, if what is taken into account is the function of the substantial modules, then it seems to be a conceptual connection from modularity to substantial innateness. (shrink)

Following the pragmatic practices of anesthesiologists an individual is defined to be in a state of consciousness empirically by the behavioral ability to respond to simple stimuli and the loss of consciousness is defined by the loss of that facility. Several brain activities are proposed as properties of the state of consciousness. Baseline brain energy consumption has been shown by 13C MRS to be almost completely used for neuronal signaling. PET measurements of glucose or oxygen consumption, from several laboratories, show (...) a widespread ~45% reduction in cerebral energy during anesthesia-induced loss of consciousness. We propose that the high level of brain energy consumption of the awake state is a necessary property of the state of consciousness. Two additional neuronal properties are drastic changes in the patterns of fMRI activation and neuronal population activity at deep vs. light levels of anesthesia, which correspond to low vs. high energy states, respectively. The brain-wide fMRI activity patterns with rat sensory stimulation at the higher energy state collapses to contralateral somatosensory response at the lower energy state. Firing rates of an ensemble of neurons in the rat somatosensory cortex show that most of the energy in light anesthesia is consumed in the spiking frequency range of 20-40 Hz, which include γ-band electrical signals. In deep anesthesia the frequency range shifts to below 10 Hz. The high brain energy consumption, characteristic of the state of consciousness, supports elevated levels of high frequency neuronal firing observed in the resting, awake brain. In our model, necessary brain properties of the state of consciousness create our physical understanding of that state rather than the converse, popular in neuroimaging, in which subjective mental processes are identified to be necessary and sufficient correlates of the state of consciousness.
