Do young children have a teleological conception of the essence of natural kinds? We tested this by examining how the preservation or alteration of an animal’s purpose affected children’s persistence judgments (N = 40, ages 4 - 12, Mean Age = 7.04, 61% female). We found that even when surface-level features of an animal (e.g., a bee) were preserved, if the entity’s purpose changed (e.g., the bee now spins webs), children were more likely to categorize the entity as a member (...) of a different natural kind (e.g., a spider) and these effects were similar in magnitude to altering the surface-features of a natural kind. Our results suggest that we might view teleological properties as partially constitutive of the essence of natural kinds. (shrink)

We introduce the notions of syntactic synonymy and referential syn- onymy due to Moschovakis. Those notions are capable of accounting for fine- grained aspects of the meaning of linguistic expressions, by formalizing the Fregean distinction between sense and denotation. We integrate Moschovakis’s theory with the theory of concepts developed in the foundational ontology DOLCE, in order to enable a formal treatment of equivalence between concepts.

We present an algorithm for concept combination inspired and informed by the research in cognitive and experimental psychology. Dealing with concept combination requires, from a symbolic AI perspective, to cope with competitive needs: the need for compositionality and the need to account for typicality effects. Building on our previous work on weighted logic, the proposed algorithm can be seen as a step towards the management of both these needs. More precisely, following a proposal of Hampton [1], it combines two weighted (...) Description Logic formulas, each defining a concept, using the following general strategy. First it selects all the features needed for the combination, based on the logical distinc- tion between necessary and impossible features. Second, it determines the threshold and assigns new weights to the features of the combined concept trying to preserve the relevance and the necessity of the features. We illustrate how the algorithm works exploiting some paradigmatic examples discussed in the cognitive literature. (shrink)

Resumen La metáfora de la "descomposición" domina aún nuestra manera usual de pensar el análisis conceptual. Se trata de una herramienta muy útil para pensar este proceso tan abstracto, pero tiene limitaciones importantes. Por ejemplo, nos hace pensar que los componentes de un concepto deben estar en algún sentido contenidos en él o que la única manera en que dos conceptos pueden estar relacionados es que uno contenga al otro. Estas limitaciones no nos permiten dar cuenta de conceptos complejos cuya (...) estructura no es tan simple, como los de color o de medida. Por ello es tiempo de superar esta metáfora y pensar al análisis conceptual no sólo como descomposición, sino también como la asignación de diferentes funciones a los componentes de un concepto.Our customary way of thinking about conceptual analysis remains dominated by the metaphor of 'containment', which has certainly been very useful, but which also has important limitations. For example, it makes us think that the components of a concept must be, in some sense, contained in it or that the only way that two concepts can be related is if one contains the other. These limitations have not allowed us to account for concepts whose structure is not so simple, such as the concepts of color or measurement, among others. It is time, therefore, to overcome this metaphor and think of conceptual analysis not only as decomposition but also as the assignment of different functions to the components of a concept. (shrink)

This paper describes an AFOSR-supported basic research program that focuses on developing a new framework for combining hard with soft data in order to improve space situational awareness. The goal is to provide, in an automatic and near real-time fashion, a ranking of possible threats to blue assets (assets trying to be protected) from red assets (assets with hostile intentions). The approach is based on Conceptual Spaces models, which combine features from traditional associative and symbolic cognitive models. While Conceptual Spaces (...) are revolutionary, they lack an underlying mathematical framework. Several such frameworks have attempted to represent Conceptual Spaces, but by far the most robust is the model developed by Holender. His model utilizes integer linear programming in order to obtain an overall similarity value between observations and concepts that support the formation of hypotheses. This paper will describe a method for building Conceptual Spaces models for threats that utilizes ontologies as a means to provide a clear semantic foundation for this inferencing process; in particular threat ontologies and space domain ontologies are developed and employed in this approach. A space situational awareness use-case is presented involving a kinetic kill scenario and results are shown to assess the performance of this fusion-based inferencing framework. (shrink)

Destutt de Tracy zielt darauf ab, zu erklären, wie inter- und transsubjektive Prozesse auf das einzelne Individuum wirken und es gestalten. Dafür braucht er eine externalistische Sprachtheorie und eine sensualistische kognitive Architektur, nach der Denken Empfinden ist. Das Denken ist relational, aber wird nicht auf kognitiver Ebene durch sprachähnliche Strukturen – durch die Syntax und Semantik einer Mentalsprache – implementiert. Obwohl Externalismus und sensualistische Architektur in eine inkohärente Theorie zu münden scheinen, versucht Destutt de Tracy die Spannung durch seine Entwicklungsgeschichte (...) zu lösen, nach der Systematizität als assoziativ und symbolisch, aber nicht als sprachlich analysiert wird. Zum Denken ist eine Sprache notwendig, aber das Denken ist keine Mentalsprache. -/- „[Wir sind] fast gänzlich das Werk Der Umstände, die uns umgeben.“ [Ideenlehre I, 273/388]. (shrink)

The topic of my paper is the virtual controversy between Leibniz and Lockeover concepts and ideas. At the end of the 17th century John Locke made a crucial contribution to semantics and philosophy: An Essay Concerning Human Understanding. The work represents a decisive turning point for the discussion about ideas and innatism. Indeed, Locke’s aim was to dismantle the Cartesian theory according to which ideas are innate in our soul. Against this onto-epistemological thesis, Locke maintains that all our knowledge starts (...) off with experience: ideas are mental representations depending on subjects’ sensual experiences and reflection skills. Some years later, in his notes on Locke’s Essay, Leibniz writes that Locke dealt with a fundamental topic: human understanding and the limits of human knowledge (NE p. 4). All we can find out about the world is determined by answering the question about what we can know; nonetheless, Leibniz argues in favor of innate ideas. My thesis is that in his opinion Locke’s empiricism can be conciliated with the assumption that there are innate ideas. (shrink)

In our target article, we argued that the number sense represents natural and rational numbers. Here, we respond to the 26 commentaries we received, highlighting new directions for empirical and theoretical research. We discuss two background assumptions, arguments against the number sense, whether the approximate number system represents numbers or numerosities, and why the ANS represents rational numbers.

On a now orthodox view, humans and many other animals possess a “number sense,” or approximate number system, that represents number. Recently, this orthodox view has been subject to numerous critiques that question whether the ANS genuinely represents number. We distinguish three lines of critique – the arguments from congruency, confounds, and imprecision – and show that none succeed. We then provide positive reasons to think that the ANS genuinely represents numbers, and not just non-numerical confounds or exotic substitutes for (...) number, such as “numerosities” or “quanticals,” as critics propose. In so doing, we raise a neglected question: numbers of what kind? Proponents of the orthodox view have been remarkably coy on this issue. But this is unsatisfactory since the predictions of the orthodox view, including the situations in which the ANS is expected to succeed or fail, turn on the kind of number being represented. In response, we propose that the ANS represents not only natural numbers, but also non-natural rational numbers. It does not represent irrational numbers, however, and thereby fails to represent the real numbers more generally. This distances our proposal from existing conjectures, refines our understanding of the ANS, and paves the way for future research. (shrink)

In this paper, I argue that an adequate meta-semantic framework capable of accommodating the range of projects currently identified as projects in conceptual engineering must be sensitive to the fact that concepts (and hence projects relating to them) fall into distinct kinds. Concepts can vary, I will argue, with respect to their direction of determination, their modal range, and their temporal range. Acknowledging such variations yields a preliminary taxonomy of concepts and generates a meta-semantic framework that allows us both to (...) accommodate the full range of cases and to identify a proper subset of concepts for special ameliorative consideration. Ignoring such variations, in contrast, leads to a restricted meta-semantic framework that accommodates only a subset of the particular projects while generating implausible accounts of others.

This book evaluates whether or not we can decide on the best theory of concepts by appealing to the explanatory results of cognitive science. It undertakes an in-depth analysis of different theories of concepts and of the explanations formulated in cognitive science. As a result, two reasons are provided for thinking that an appeal to cognitive science cannot help to decide on the best theory of concepts.

_Concept Formation_ is the final part of the trilogy _Forms of Representation in the Aristotelian Tradition_. It investigates some of the most perplexing and provocative discussions on conceptual thinking in the Greek, Latin, and Arabic reception of Aristotle’s psychology.

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

Philosophers often rely on the notion of conceptual containment and apply mereological terminology when they talk about the parts or constituents of a complex concept. In this paper, I explore two historical approaches to this general notion. In particular, I reconstruct objections Bernard Bolzano puts forward against a criterion that played a prominent role in the history of philosophy and that was endorsed, among others, by Leibniz. According to this criterion, a concept that represents objects contains all and only the (...) concepts that represent properties the objects must have in order to be represented by the former concept. Bolzano offers several counterexamples and arguments against the criterion. I argue that while some of them presuppose a strongly mereological understanding of containment, which Leibniz is not committed to, one of them also succeeds without relying on demanding mereological principles.

How are biases encoded in our representations of social categories? Philosophical and empirical discussions of implicit bias overwhelmingly focus on salient or statistical associations between target features and representations of social categories. These are the sorts of associations probed by the Implicit Association Test and various priming tasks. In this paper, we argue that these discussions systematically overlook an alternative way in which biases are encoded, that is, in the dependency networks that are part of our representations of social categories. (...) Dependency networks encode information about how features in a conceptual representation depend on each other. This information determines the degree of centrality of a feature for a conceptual representation. Importantly, centrally encoded biases systematically disassociate from those encoded in salient-statistical associations. Furthermore, the degree of centrality of a feature determines its cross-contextual stability: in general, the more central a feature is for a concept, the more likely it is to survive into a wide array of cognitive tasks involving that concept. Accordingly, implicit biases that are encoded in the central features of concepts are predicted to be more resilient across different tasks and contexts. As a result, the distinction between centrally encoded and salient-statistical biases has important theoretical and practical implications. (shrink)

Truth, knowledge, justice – to understand how our loftiest abstractions earn their keep, trace them to their practical origins.

Why is the concept of truth so important to us? After all, it is not at all obvious why human intelligence would have evolved to do anything other than to dissimulate, deceive, cheat, and trick. Pragmatic genealogies like the genealogies of the value of truth told by Nietzsche and Williams can help us grasp why we think as we do. But instead of explaining concepts by tracing them to antecedent objects in reality, they trace them to practical needs and reverse-engineer (...) the functions performed by the concepts. (shrink)

Esiste, oltre alle singole cose rosse, la proprietà universale "rosso"? O esistono invece solo le entità individuali e particolari? Come spiegare il fatto che più entità tra loro distinte possono essere tuttavia uguali per un determinato aspetto? E che cos'è che distingue due entità che condividano esattamente le stesse proprietà? Questi sono alcuni dei problemi che costituiscono la questione degli universali e dei particolari, che, a partire dai dialoghi platonici e dalla metafisica di Aristotele, ha sempre rappresentato uno dei nodi (...) centrali dell'ontologia. Di tale questione il libro ripercorre le tappe storiche principali, partendo dalla formulazione che ne fu proposta nell'antichità, esaminando gli importanti e variegati sviluppi medievali, individuandone la presenza talvolta nascosta nella filosofia moderna e ricostruendo i dibattiti della metafisica contemporanea, che ha visto una significativa rinascita di interesse per questi temi, soprattutto nell'ambito della filosofia analitica. -/- (English version) Does there exist, besides single red things, a universal red property? Or are there only individual, particular entities? How does one explain the fact that many distinct entities can be considered the same as regards a specific feature? And what is it exactly that distinguishes two things that share the exact same property? These are some of the questions that involve universals and particulars, a general issue that, ever since Plato's dialogues and Aristotle's Metaphysics, has played a crucial role in ontology. This book outlines the evolution of this issue through its main historical phases, from its initial conception in ancient times, through its medieval development, up to its sometimes hidden presence in modern philosophy. The text also addresses contemporary debates in metaphysics, in which there is a significant revival of interest for this topic, especially in analytical philosophy. (shrink)

Theories of relations between language and conceptual development benefit from empirical evidence for concepts available in infancy, but such evidence is comparatively scarce. Here, we examine early representations of specific concepts, namely, sets of dynamic events corresponding either to predicates involving two variables with a reversible, asymmetric relation between them (such as the set of all events that correspond to a linguistic phrase like “a dog is pushing a car,”) or to comparatively simpler, one-variable predicates (such as the set of (...) events corresponding to a phrase like “a dog is jumping.”). We develop a non-linguistic, anticipatory eye-tracking task that can be administered to both infants and adults, and we use this task to gather evidence for the formation and use of such one-and two-place-predicate classes (which we refer to as event sortals) in 12–24-mo-old infants, and in adults with and without concurrent verbal prose shadowing. Using visually similar stimuli for both the simpler (one-place) and the more complex (reversible, asymmetric, two-place) concepts, we find that infants only show evidence for forming and generalizing one-place event sortals, and, while adults succeed with both kinds in the absence of verbal shadowing, shadowing hampers their ability to form and use the asymmetric two-place event sortals. In a subsequent experiment with adults, we find that if the shadowing material is grammatically impoverished, adults now succeed in forming and using both one- and two-place event sortals. We discuss implications of these results for theories of concept acquisition, and the role of language in this process. (shrink)

This book develops and defends a version of physicalism in contemporary philosophy of mind, called ‘No-Self Physicalism’. No-Self Physicalism emphasizes that a subject of cognition is itself a physical entity, a human brain (and body). -/- The book first argues (in Chapters 1 and 2) that many contemporary philosophers who openly accept physicalism in fact (though perhaps unconsciously and/or implicitly) take the stance of a non-physical Subject in understanding and using core philosophical notions, such as conceptual representation, truth, analyticity, modality, (...) apriority, abstract object, knowledge and intuition. That is, they appear to be unaware that our traditional understandings of these philosophical notions presuppose a non-physical Subject. They appear to be unaware that these notions need a radical overhaul to become meaningful if, according to physicalism, the subject of cognition is itself a plain physical object, not any obscure, amorphous, non-physical, soul-like Subject. This problem threatens the coherence of many contemporary philosophers’ philosophical positions. -/- Then, the bulk of this book (Chapters 3 to 7) consists of laborious efforts to develop truly physicalistic theories on some core philosophical notions and issues, including (in the order of presentation in this book) concepts and conceptual representation, thoughts and truth, belief ascription, analyticity, modality, the nature of mathematics, epistemic justification, knowledge, apriority, intuition, and a physicalistic ontology. These physicalistic theories explicitly assume that a subject of cognition is a human brain (and body), or a neural network-based robot programmed by evolution. They are new and are more clearly physicalistic if compared with their alternatives in the current literature. Finally, the last chapter (Chapter 8) of this book uses the physicalistic notions of conceptual representation, truth, analyticity, modality, knowledge, apriority, intuition, and the physicalistic ontology developed in previous chapters to formulate physicalism as a general philosophical worldview. This is then an internally coherent formulation of physicalism, using only naturalized philosophical notions. It helps to settle the current debates between different versions of physicalism. -/- Therefore, on the one side, this book tries to push physicalism to its extreme, in its most radical format, by emphasizing that the cognitive subject is itself a completely physical thing, a neural network-based robot programmed by evolution, but on the other side, by some hard work, some honest toil, it tries to demonstrate that this minimal physicalistic framework can already offer accounts for many core philosophical notions and issues that traditionally interest philosophers, namely, conceptual representation, truth, analyticity, belief ascription, modality, the nature of mathematics, epistemic justification, knowledge, apriority, intuition and some ontological issues. It is meant to be a self-contained presentation of a very radical and strict version of physicalism while at the same time showing how surprisingly comprehensive this version could be. (shrink)

According to one of the most powerful paradigms explaining the meaning of the concept of natural number, natural numbers get a large part of their conceptual content from core cognitive abilities. Carey’s bootstrapping provides a model of the role of core cognition in the creation of mature mathematical concepts. In this paper, I conduct conceptual analyses of various theories within this paradigm, concluding that the theories based on the ability to subitize, or on the ability to approximate quantities, or both, (...) fail to provide a conceptual basis for bootstrapping the concept of an exact natural number. In particular, I argue that none of the existing theories explains one of the key characteristics of the natural number structure: the equidistances between successive elements of the natural numbers progression. I suggest that this regularity could be based on another innate cognitive ability, namely sensitivity to the regularity of rhythm. In the final section, I propose a new position within the core cognition paradigm, inspired by structuralist positions in philosophy of mathematics. (shrink)

In psychological research, ressentiment is alluded to as a negative emotional response directed at social groups that are mostly marked as ‘inferior others’. However, conceptual work on this notion is sorely missing. In our conceptual proposal, we use the notion of ‘moral emotions’ as a starting point: typically referred to as “other-condemning” moral emotions, psychologists have loosely conceptualised anger, contempt and disgust as a set of negative emotions that have distinct elicitors and involve affective responses to sanction moral misconduct of (...) ‘others’. Though this conglomerate of different other-condemning emotions might describe emotions of ressentiment, we argue that the phenomenon itself is a more complex sentiment. Therefore, we apply Withy’s concept of ‘disclosive posture’ to account for the different psychological processes underlying ressentiment. Disclosing refers to a specific openness to the world, which in the case of ressentiment implies a specific awareness of and sensibility for instances of inequality, grudge, or disfavour. Ressentiment thus becomes a perceptual tool in morally relevant everyday situations. The term ‘posture’ refers to a habitualised, embodied comportment or action tendency that leads to the adoption of a negative attitude and stance towards others. Drawing on Withy, we discuss ressentiment’s similarities to the closely related concept of hatred to embed the analysis of ressentiment in a broader social framework. (shrink)

In psycholinguistics, concepts are considered abstract if they do not apply to physical objects that we can touch, see, feel, hear, smell or taste. Psychologists usually distinguish concrete from abstract concepts by means of so-called concreteness ratings. In concreteness rating studies, laypeople are asked to rate the concreteness of words based on the above criterion. The wide use of concreteness ratings motivates an assessment of them. I point out two problems: First, most current concreteness ratings test the intuited concreteness of (...) word forms as opposed to concepts. This ignores the ubiquitous phenomenon of lexical ambiguity. Second, the criterion of abstract concepts that the instruction texts of rating studies rely on does not capture the notion that psychologists working on abstract concepts are normally interested in, i.e., concepts that could reasonably be sensorimotor representations. For many concepts that pick out physical objects, this is not reasonable. In this paper, I propose a characterization of concrete and abstract concepts that avoids these two problems and that may be useful for future studies in psychology. (shrink)

The embodied approach of human cognition suggests that concepts are deeply dependent upon and constrained by an agent's physical body's characteristics, such as performed body movements. In this study, we attempted to broaden previous research on emotional priming, investigating the interaction of emotions and visual exploration. We used the joystick-based approach-avoidance task to influence the emotional states of participants, and subsequently, we presented pictures of news web pages on a computer screen and measured participant's eye movements. As a result, the (...) number of fixations on images increased, the total dwell time increased, and the average saccade length from outside of the images toward the images decreased after the bodily congruent priming phase. The combination of these effects suggests increased attention to web pages' image content after the participants performed bodily congruent actions in the priming phase. Thus, congruent bodily interaction with images in the priming phase fosters visual interaction in the subsequent exploration phase. (shrink)

Investigates the hypothesis that spatial processes are involved in judgments on membership in a category. It is argued that membership versus non-membership of an object or a concept, in a category, is spatially simulated in mental space by a minimal continuum with 2 levels, left for membership and right for non-membership. In analogy to other embodied dimensions (e.g., time line or number line), the orientation of membership levels on the mental dimension is assumed to follow the acquired reading/writing schema, with (...) procedural primacy implying dominance, hence leftward positioning of dominant elements. This rationale is tested in 7 experiments. A recognition memory paradigm (modified 2AFC paradigm, Experiment 1) revealed that participants were faster indicating the location of an old word on the screen when displayed left within a pair of words, indicating a spatial representation of category membership (“member” = left, “nonmember” = right). For category discrimination (Experiment 2) we found faster and more accurate performance when a target word is presented left as compared with right. This pattern is replicated in Experiments 4a and 4b, with different response alternatives. Discriminating categories in a stimulus-response compatibility paradigm (Experiment 3), participants were faster making correct responses with their left hand than with their right hand in target category trials. In contrast, no differences were found for distractor trials. Experiments 5a and 5b address the spatial bias in spontaneous sorting situations. Overall, this pattern of results across the 7 experiments provides evidence in support of a spatial simulation of category assignment. (shrink)

Increasingly, in data-intensive areas of the life sciences, experimental results are being described in algorithmically useful ways with the help of ontologies. Such ontologies are authored and maintained by scientists to support the retrieval, integration and analysis of their data. The proposition to be defended here is that ontologies of this type – the Gene Ontology (GO) being the most conspicuous example – are a part of science. Initial evidence for the truth of this proposition (which some will find self-evident) (...) is the increasing recognition of the importance of empirically-based methods of evaluation to the ontology development work being undertaken in support of scientific research. The ontologies created by scientists must, of course, be associated with implementations satisfying the requirements of software engineering. But these ontologies are not themselves engineering artifacts, and to conceive them as such brings grievous consequences. Rather, we shall argue, ontologies such as the GO are comparable to scientific theories, to scientific databases, or to scientific journal publications. Such a view implies a radically new conception of what is involved in the authoring, maintenance and application of ontologies in scientific contexts, and therewith also a radically new approach to the evaluation of ontologies and to the training of ontologists.

In recent years, language has been shown to play a number of important cognitive roles over and above the communication of thoughts. One hypothesis gaining support is that language facilitates thought about abstract categories, such as democracy or prediction. To test this proposal, a novel set of semantic memory task trials, designed for assessing abstract thought non-linguistically, were normed for levels of abstractness. The trials were rated as more or less abstract to the degree that answering them required the participant (...) to abstract away from both perceptual features and common setting associations corresponding to the target image. The normed materials were then used with a population of people with aphasia to assess the relationship of abstract thought to language. While the language-impaired group with aphasia showed lower overall accuracy and longer response times than controls in general, of special note is that their response times were significantly longer as a function of a trial’s degree of abstractness. Further, the aphasia group’s response times in reporting their degree of confidence (a separate, metacognitive measure) were negatively correlated with their language production abilities, with lower language scores predicting longer metacognitive response times. These results provide some support for the hypothesis that language is an important aid to abstract thought and to metacognition about abstract thought. (shrink)

Most theories of concepts take concepts to be structured bodies of information used in categorization and inference. This paper argues for a version of atomism, on which concepts are unstructured symbols. However, traditional Fodorian atomism is falsified by polysemy and fails to provide an account of how concepts figure in cognition. This paper argues that concepts are generative pointers, that is, unstructured symbols that point to memory locations where cognitively useful bodies of information are stored and can be deployed to (...) resolve polysemy. The notion of generative pointers allows for unresolved ambiguity in thought and provides a basis for conceptual engineering. (shrink)

According to conceptual metaphor theory, individuals are thought to understand or express abstract concepts by using referents in the physical world—right and left for moral and immoral, for example. In this research, we used a modified Stroop paradigm to explore how abstract moral concepts are metaphorically translated onto physical referents in Chinese culture using the Chinese language. We presented Chinese characters related to moral and immoral abstract concepts in either non-distorted or distorted positions or rotated to the right or to (...) the left. When we asked participants to identify the Chinese characters, they more quickly and accurately identified morally positive characters if they were oriented upright or turned to the right and more quickly and accurately identified immoral characters when the characters were distorted or rotated left. These results support the idea that physical cues are used in metaphorically encoding social abstractions and moral norms and provided cross-cultural validation for conceptual metaphor theory, which would predict our results.

The principle of compositionality claims that the content of a complex concept is determined by its constituent concepts and the way in which they are composed. However, for prototype concepts this principle is often too rigid. Blurring the division between conceptual composition and belief update has therefore been suggested. Inspired by this idea, we develop a normative account of how belief revision and meaning composition should interact in modifications such as “red apple” or “pet hamster”. We do this by combining (...) the well-known selective modification model :485–527 1988) with the rules of Bayesian belief update. Moreover, we relate this model to systems of defeasible reasoning as discussed in the field of artificial intelligence. (shrink)

Embracing an inter-disciplinary approach grounded on Gärdenfors’ theory of conceptual spaces, we introduce a formal framework to analyse and compare selected theories about technical artefacts present in the literature. Our focus is on design-oriented approaches where both designing and manufacturing activities play a crucial role. Intentional theories, like Kroes’ dual nature thesis, are able to solve disparate problems concerning artefacts but they face both the philosophical challenge of clarifying the ontological nature of intentional properties, and the empirical challenge of testing (...) the attribution of such intentional properties to artefacts. To avoid these issues, we propose an approach that, by identifying different modalities to characterise artefact types, does not commit to intentional qualities and is able to empirically ground compliance tests.

We present a systematic and qualitative review of academic literature on early conceptual development (0–24 months of age), with an emphasis on methodological aspects. The final sample of our review included 281 studies reported in 115 articles. The main aims of the article were four: first, to organise studies into sets according to methodological similarities and differences; second, to elaborate on the methodological procedures that characterise each set; third, to circumscribe the empirical indicators that different sets of studies consider as (...) proof of the existence of concepts in early childhood; last, to identify methodological limitations and to propose possible ways to overcome them. We grouped the studies into five sets: preference and habituation experiments, category extension tasks, object sorting tasks, sequential touching tasks and object examination tasks. In the “Results” section, we review the core features of each set of studies. In the “Discussion” and “Conclusions” sections, we describe, for one thing, the most relevant methodological shortcomings. We end by arguing that a situated, semiotic and pragmatic perspective that emphasises the importance of ecological validity could open up new avenues of research to better understand the development of concepts in early childhood.

This dissertation defends the view that concepts encode causal information and, for the first time, applies this view to a range of topics in the philosophy of language and social philosophy. In my first chapter (“Cognitive Essentialism and the Structure of Concepts”), I survey the current empirical and theoretical literature on causal-essentialist theories of concepts. In my second chapter (“Meaning Externalism and Causal Model Theory”), I propose an account of natural kind concepts according to which they encode statistical information of (...) features of a natural kind, and represents these features as causally related to each other. I show that this internalist model of concepts correctly predicts intuitions about Putnam’s twin earth scenario and Kripke’s conceivability cases that historically motivated philosophers of language to accept externalist accounts of meaning. The defended theory of concepts also informs topics that go beyond traditional issues in philosophy of language. In my third chapter (“An Essentialist Theory of the Meaning of Slurs”), I defend the view that slurs are, too, a species of kind terms: slur concepts encode mini-theories which represent an essence-like element that is causally connected to a set of negatively-valenced stereotypical features of a social group. This explains both the peculiar linguistic behavior of slurs and slurs’ dehumanizing effects. In my fourth chapter, I build on this insight, showing that the explicit language in and around pornography depicts women as ‘kinds’ or ‘breeds’ that are naturally made to enjoy certain sexual acts, and argue that this deterministic picture of women dehumanizes them.

Conceptual engineers aim to revise rather than describe our concepts. But what are concepts? And how does one engineer them? Answering these questions is of central importance for implementing and theorizing about conceptual engineering. This paper discusses and criticizes two influential views of this issue: semanticism, according to which conceptual engineers aim to change linguistic meanings, and psychologism, according to which conceptual engineers aim to change psychological structures. I argue that neither of these accounts can give us the full story. (...) Instead, I propose and defend the Dual Content View of Conceptual Engineering. On this view, conceptual engineering targets concepts, where concepts are understood as having two kinds of contents: referential content and cognitive content. I show that this view is independently plausible and that it gives us a comprehensive account of conceptual engineering that helps to make progress on some of the most difficult problems surrounding conceptual engineering.

Informational theories of semantic content have been recently gaining prominence in the debate on the notion of mental representation. In this paper we examine new-wave informational theories which have a special focus on cognitive science. In particular, we argue that these theories face four important difficulties: they do not fully solve the problem of error, fall prey to the wrong distality attribution problem, have serious difficulties accounting for ambiguous and redundant representations and fail to deliver a metasemantic theory of representation. (...) Furthermore, we argue that these difficulties derive from their exclusive reliance on the notion of information, so we suggest that pure informational accounts should be complemented with functional approaches.

What Stanislas Debaene dubs "the number sense" is a natural ability humans share with other animals, enabling us to "count" to four virtually instantaneously. This so-called "accumulator" provides "a direct intuition of what numbers mean". Beyond four, our ability to perceive numbers becomes approximate, though concepts enable us to move beyond approximation. Because humans typically learn number concepts in early childhood, we easily forget that our brains retain the number sense throughout life. This book examines the biological basis for this (...) intuitive ability, with nine chapters organized into three readily graspable groups of three. Aside from its frustrating lack of a clear referencing system, the book is a pleasure to read. (shrink)

Can the theory of conceptual spaces developed by Peter Gärdenfors and others be applied to moral issues? Martin Peterson argues that several moral principles can be construed as regions in a shared similarity space, but Kristin Shrader-Frechette and Gert-Jan Lokhorst question Peterson’s claim. They argue that the moral similarity judgments used to construct the space are underspecified and subjective. In this paper, we present new data indicating that moral principles can indeed be construed as regions in a multidimensional conceptual space (...) on the basis of moral similarity judgments. Four hundred and seventy-five students taking a course in engineering ethics completed a survey in which they were presented with ten cases featuring ethical issues related to technology and engineering. Participants were asked to judge the moral similarity of each pair of cases and to select which moral principle they believed should be applied for resolving the case. We used interval multidimensional scaling as well as individual differences scaling for analyzing the moral similarity judgments. Despite noteworthy individual variations in the judgments, the five moral principles included in the study were discernable in the aggregate multidimensional spaces, even for participants with no previous exposure to the principles. Participants tended to apply the same moral principles to cases rated as morally similar. Our overall conclusion is that moral similarity judgments, and their representation in multidimensional spaces, can help us identify moral principles that are relevant for assessing difficult moral choice situations.

The influential apoha theory of concept formation of the seventh-century Buddhist Dharmakīrti stands as a philosophically powerful articulation of how language could work in the absence of real universals. In brief, Dharmakīrti argues that concepts are constructed through a goaloriented process that delimits the content of an experience by ignoring whatever does not conform to one's conditioned expectations. There are no real similarities that ground this process.

The hard problem of consciousness is about how we could explain in physicalist terms why we are conscious. The meta-problem of consciousness is about how we could explain why we have a hard problem of consciousness. In this note I argue that the phenomenal concept strategy can in principle provide a satisfactory solution to the meta-problem.

The surface grammar of reports such as ‘I have a pain in my leg’ suggests that pains are objects which are spatially located in parts of the body. We show that the parallel construction is not available in Mandarin. Further, four philosophically important grammatical features of such reports cannot be reproduced. This suggests that arguments and puzzles surrounding such reports may be tracking artefacts of English, rather than philosophically significant features of the world.

Content-externalism is the view that a subject’s relations to a context can play a role in individuating the content of her mental states. According to social content-externalists, relations to a socio-linguistic context can play a fundamental individuating role. Åsa Wikforss has suggested that ‘social externalism depends on the assumption that individuals have an incomplete grasp of their own concepts’ (Wikforss 2004, p. 287). In this paper, I show that this isn’t so. I develop and defend an argument for social content-externalism (...) which does not depend on this assumption. The argument is animated by strands of thought in the later work of Wittgenstein. In addition to demonstrating that social externalists are not necessarily committed to thinking that a subject can have thoughts involving concepts which she incompletely understands, this argument is important insofar as it: (1) supports a form of content-externalism with extended scope; (2) avoids the controversy surrounding the claim that subjects can think with concepts which they incompletely understand; and (3) situates Wittgenstein’s later work with respect to contemporary debates about content-externalism.

The Twin Earth thought experiment invites us to consider a liquid that has all of the superficial properties associated with water (clear, potable, etc.) but has entirely different deeper causal properties (composed of “XYZ” rather than of H2O). Debates about natural kind concepts have sought to accommodate an apparent fact about ordinary people's judgments: Intuitively, the Twin Earth liquid is not water. We present results showing that people do not have this intuition. Instead, people tend to judge that there is (...) a sense in which the liquid is not water but also a sense in which it is water.

The Twin Earth thought experiment invites us to consider a liquid that has all of the superficial properties associated with water (clear, potable, etc.) but has entirely different deeper causal properties (composed of “XYZ” rather than of H2O). Although this thought experiment was originally introduced to illuminate questions in the theory of reference, it has also played a crucial role in empirically informed debates within the philosophy of psychology about people’s ordinary natural kind concepts. Those debates have sought to accommodate (...) an apparent fact about ordinary people’s judgments: Intuitively, the Twin Earth liquid is not water. We present results from four experiments showing that people do not, in fact, have this intuition. Instead, people tend to have the intuition that there is a sense in which the liquid is not water but also a sense in which it is water. We explore the implications of this finding for debates about theories of natural kind concepts, arguing that it supports views positing two distinct criteria for membership in natural kind categories – one based on deeper causal properties, the other based on superficial, observable properties.

At least in one well-motivated sense of ‘concept’, all perception involves concepts, even perception as practiced by lizards and bees. That is because—the paper argues—all perception involves belief.

Between the end of the nineteenth century and the first twenty years of the twentieth century, stimulated by the impetuous development of logical studies and taking inspiration from Leibniz's idea of a characteristica universalis, the three founding fathers of the analytic tradition in philosophy, i.e., Frege, Russell, and Wittgenstein, started to talk of a logically perfect language, as opposed to natural languages, all feeling that the latter were inadequate to their (different) philosophical purposes. In the second half of the twentieth (...) century, however, the very idea of a logically perfect language ceased for various reasons to seem attractive to analytic philosophers. Thus, it might appear that this idea could be classified together with the many other bizarre ideas that from time to time surface in the history of philosophy-an idea that perhaps had a beneficial impact on the development of twentieth century logic, but which can now be put to rest. In this brief note, I contend that this conclusion may be too hasty. Indeed, if a well-known empirical hypothesis advanced in 1975 by Jerry Fodor turns out to be true, then there is a logically perfect language, after all. More precisely, I argue that, if it exists, Fodor's language of thought possesses the main characteristics a logically perfect language is required to have. (shrink)

Art theory has consistently emphasised the importance of situational, cultural, institutional and historical factors in viewers’ experience of fine art. However, the link between this heavily context-dependent interpretation and the workings of the mind is often left unexamined. Drawing on relevance theory—a prominent, cogent and productive body of work in cognitive pragmatics—we here argue that fine art achieves its effects by prompting the use of cognitive processes that are more commonly employed in the interpretation of words and other stimuli presented (...) in a communicative context. We describe in particular how institutional factors effectively co-opt these processes for new ends, allowing viewers to achieve cognitive effects that they otherwise would not, and so provide cognitivist backing for an Institutional Theory of Art, such as that put forward by Arthur Danto. More generally, we situate and describe the Western fine art tradition as a phenomenon that is a consequence of both the cognitive processes involved in communication, and of cultural norms, practices and institutions.

According to the so-called ‘standard theory’ of conditions, the conditionship relation is converse, that is, if A is a sufficient condition for B, B is a necessary condition for A. This theory faces well-known counterexamples that appeal to both causal and other asymmetric considerations. I show that these counterexamples lose their plausibility once we clarify two key components of the standard theory: that to satisfy a condition is to instantiate a property, and that what is usually called ‘conditionship relation’ is (...) an inferential relation. Throughout the paper this way of interpreting the standard theory is compared favourably over an alternative interpretation that is outlined in causal terms, since it can be applied to all counterexamples without losing its intuitive appeal.

Advocates of the pictorial theory of meaning claimed that the meaning of a word is a mental picture and that lexical semantic competence --i.e. knowledge of word meaning -- is closely connected to visual imagery. As a philosophical theory of meaning, the pictorial theory was discredited in the twentieth century. Nevertheless, there is evidence that visual imagery -- the generation of visual mental images -- does play a role in semantic processing and is not just a possible side effect of (...) it. The aim of this article is to critically assess the neuroscientific status of the pictorial theory of meaning as a hypothesis about the neurocognitive underpinnings of lexical semantic competence. I will assess relevant neuroimaging, behavioural, and patient data, as well as data from congenital blindness studies. (shrink)
