What are mental states? When we talk about people’s beliefs or desires, are we talking about what is happening inside their heads? If so, might cognitive science show that we are wrong? Might it turn out that mental states do not exist? Mental fictionalism offers a new approach to these longstanding questions about the mind. Its core idea is that mental states are useful fictions. When we talk about mental states, we are not formulating hypotheses about people’s inner machinery. Instead, (...) we simply talk "as if" people had certain inner states, such as beliefs or desires, in order to make sense of their behaviour. This is the first book dedicated to exploring mental fictionalism. Featuring contributions from established authors as well as up-and-coming scholars in this burgeoning field, the book reveals the exciting potential of a fictionalist approach to the mind, as well as the challenges it faces. In doing so, it offers a fresh perspective on foundational debates in the philosophy of mind, such as the nature of mental states and folk psychology, as well as hot topics in the field, such as embodied cognition and mental representation. Mental Fictionalism: Philosophical Explorations essential reading for advanced undergraduates, postgraduates and professionals alike. (shrink)

This note is concerned with Ned Block's claim that cognition differs from perception in being paradigmatically conceptual, propositional, and non-iconic. As against Block, it maintains that large stretches of cognition constitutively involve, or depend on, iconic representations.

Ce deuxième tome des Hommes de la fraternité s'achève avec le règne de Constantin et le concile de Nicée (325). Les quelques deux cent cinquante évêques qui participent à ce concile dit " œcuménique " représentent bien mal, par leur provenance, ce qu'on appelait alors l'oïkouméné (l'ensemble des terres habitées). Mais le concile est présidé par l'empereur, et une ère nouvelle commence pour les chrétiens au sein de l'Empire. Ils sont si bien traités par le prince, ces évêques conciliaires, qu'ils (...) " se demandent s'ils ne sont pas déjà dans le Royaume de Dieu ". Il semble loin le temps de l'épître à Diognète (vers 195) qui parlait des chrétiens en ces termes : " toute terre étrangère leur est une patrie, toute patrie une terre étrangère. " avec Constantin s'inaugure ce qu'on appellera plus tard l'alliance du trône et de l'autel. Ce deuxième tome est celui d'un tournant décisif pour la suite de l'histoire. Mais l'historien qu'est Michel Clévenot se garde bien d'illustrer une thèse, fût-elle éclairante. Il donne au contraire à voir et à entendre la diversité des situations aux quatre coins de l'Empire et au sein des classes sociales si peu homogènes : le lecteur fait connaissance avec le " directeur de conscience " de la bourgeoisie d'Alexandrie, mais il visite aussi les petits agriculteurs d'Italie, d'Afrique du Nord ou des bords du Nil. Les querelles commerciales, les tensions économiques, les controverses théologiques, les affrontements politiques et guerriers, rien de tout cela n'est négligeable pour celui qui entend " l'appel de Jésus à ne pas déserter l'Histoire ".

This chapter argues that human and animal minds indeed depend on a collection of domain-specific, task-specific, and encapsulated cognitive systems: on a set of cognitive ‘modules’ in Fodor's sense. It also argues that human and animal minds are endowed with domain-general, central systems that orchestrate the information delivered by core knowledge systems. The chapter begins by reviewing the literature on spatial reorientation in animals and in young children, arguing that spatial reorientation bears the hallmarks of core knowledge and of modularity. (...) It then considers studies of older children and adults, arguing that human spatial representations change qualitatively over development and show capacities not found in any other species. Finally, it presents two new experiments that investigate the role of emerging spatial language in uniquely human navigation performance. (shrink)

An examination of the ways human movement can be represented as a formal language and how this language can be mediated technologically. In Motion and Representation, Nicolás Salazar Sutil considers the representation of human motion through languages of movement and technological mediation. He argues that technology transforms the representation of movement and that representation in turn transforms the way we move and what we understand to be movement. Humans communicate through movement, physically and mentally. To record and capture integrated movement (...) (both bodily and mental), by means of formal language and technological media, produces a material record and cultural expression of our evolving kinetic minds and identities. Salazar Sutil considers three forms of movement inscription: a written record (notation), a visual record (animation), and a computational record (motion capture). He focuses on what he calls kinetic formalism—formalized movement in such pursuits as dance, sports, live animation, and kinetic art, as well as abstract definitions of movement in mathematics and computer science. He explores the representation of kinetic space and spatiotemporality; the representation of mental plans of movement; movement notation, including stave notation (Labanotation) and such contemporary forms of notation as Choreographic Language Agent; and the impact of digital technology on contemporary representations of movement—in particular motion capture technology and Internet transfer protocols. Motion and Representation offers a unique cultural theory of movement and of the ever-changing ways of representing movement. (shrink)

Three experiments investigated changes from 15 to 30 months of age in children’s (N = 114) mastery of relations between an object and an aperture, supporting surface, or form. When choosing between objects to insert into an aperture, older children selected objects of an appropriate size and shape, but younger children showed little selectivity. Further experiments probed the sources of younger children’s difficulty by comparing children’s performance placing a target object in a hole, on a 2-dimensional form, or atop another (...) solid object. Together, the findings suggest that some factors limiting adults’ object representations, including the difficulty of comparing the shapes of positive and negative spaces and of representing shapes in 3 dimensions, contribute to young children’s errors in manipulating objects.

This paper analyzes Kent Bach’s representational theory of action, one of the causal theories of action. Bach’s theory sets requirements not only for the cause of an action, but also for how it unfolds in time and transitions into another action. These requirements suggest a sequential emergence of two components of the agent’s action awareness: the representation of the prepared movement and the perception of its sensory consequences. Bach introduces the concepts of “effective representation” (ER) and “receptive representation” (RR) to (...) denote these components of awareness. According to representational theory, action has a cyclic three-step causal structure, where ER is the cause of a movement, the movement is the cause of RR, and RR is the cause of ER of subsequent movement. In constructing his theory, Bach tries to take into account the problem of deviant causal chains and to introduce the so-called minimal actions into the purview of the philosophy of action. Relying on the behavioral data on blindfolded deafferentated patients, in this paper I argue that RRs are not a necessary element of action. I also analyze Bach’s distinction between ER and RR and compare it with J. Searle’s approach, placing Bach’s theory within the context of studies of the structure of intentional states. I show that Bach’s theory occupies a unique position among views on the structure of action awareness. At the same time, I conclude that the frameworks of Bach and Searle are insufficient for describing the metaphysical difference between the two kinds of intentional states, and I also point out the difficulties facing the notion of ER. Based on this reasoning and the data on deafferentated patients, I propose a modification of the causal structure of action proposed by Bach, making a remark about the inadequate definition of ER. In the proposed modification, RR and the agent’s prior intention serve as alternative components of action awareness. (shrink)

This book is devoted to discussion of the views of Pierre Musso and starts with a central chapter written by Musso, entitled Network Ideology: from Saint-Simonianism to the Internet. Pierre Musso is a French philosopher and is one of the most original thinkers in the history of the network society. His thought develops a critique of information and communication technologies through their imaginary and social representations and of the information society, based on the network metaphor. The main question on (...) which Musso has focused his attention is how the network metaphor is one of the most powerful ways of understanding the complex societies in which we live. Showing characteristic attention to detail, and drawing on the history of ideas, political philosophy and sociology, Musso traces the genealogy of the network imaginary, and points out that it did not emerge with the Internet. He shows how its modern roots can be found in Henri de Saint-Simon and his disciples, engineers and entrepreneurs such as Michel de Chevalier, and Barthélemy Prosper Enfantin, who developed channel networks, railroads, and the telegraphic network in France in the nineteenth century. In addition to the central piece written by Musso, the book includes a general introduction and six commentaries from experts on information technologies and networks. It displays a wide range of perspectives from a diverse set of authors in terms of nationalities and universities, as well as disciplinary backgrounds. (shrink)

Whether visual perceptual consciousness is gradable or dichotomous has been the subject of fierce debate in recent years. If perceptual consciousness is gradable, perceivers may have less than full access to—and thus be less than fully phenomenally aware of—perceptual information that is represented in working memory. This raises the question: In virtue of what can a subject be less than fully perceptually conscious? In this chapter, we provide an answer to this question, according to which inexact categorizations of visual input (...) may result in a representation of the visual information in working memory that is less than fully available to the perceiver, and of which the perceiver is therefore less than fully phenomenally aware. The latter proposal is a natural extension of a theory of perception we have proposed in previous works, namely, the template tuning theory (TTT). We argue that although TTT is compatible with both gradable and dichotomous conceptions of perceptual consciousness, the available empirical evidence favours a gradable conception of perceptual consciousness.

A new approach to quantum theory is proposed in this paper. The basis is taken to be theoretical variables, variables that may be accessible or inaccessible, i.e., it may be possible or impossible for an observer to assign arbitrarily sharp numerical values to them. In an epistemic process, the accessible variables are just ideal observations connected to an observer or to some communicating observers. Group actions are defined on these variables, and group representation theory is the basis for developing the (...) Hilbert space formalism here. Operators corresponding to accessible theoretical variables are derived, and in the discrete case, it is proved that the possible physical values are the eigenvalues of these operators. The focus of the paper is some mathematical theorems paving the ground for the proposed foundation of quantum theory. It is shown here that the groups and transformations needed in this approach can be constructed explicitly in the case where the accessible variables are finite-dimensional. This simplifies the theory considerably: To reproduce the Hilbert space formulation, it is enough to assume the existence of two complementary variables. The interpretation inferred from the proposed foundation here may be called a general epistemic interpretation of quantum theory. A special case of this interpretation is QBism; it also has a relationship to several other interpretations. (shrink)

We point out that, when the dimension of the Hilbert space is greater than two, Bell’s operators entering the Bell-CHSH inequality do exhibit inequivalent unitary matrix representations. Although the Bell-CHSH inequality turns out to be violated, the size of the violation is different for different representations, the maximum violation being given by Tsirelson’s bound. The feature relies on a pairing mechanism between the modes of the Hilbert space of the system.

Einstein, in his “Zur Elektrodynamik bewegter Körper”, gave a physical (operational) meaning to “time” of a remote event in describing “motion” by introducing the concept of “synchronous stationary clocks located at different places”. But with regard to “place” in describing motion, he assumed without analysis the concept of a system of co-ordinates.In the present paper, we propose a way of giving physical (operational) meaning to the concepts of “place” and “co-ordinate system”, and show how the observer can define both the (...) place and time of a remote event. Following Einstein, we consider another system “in uniform motion of translation relatively to the former”. Without assuming “the properties of homogeneity which we attribute to space and time”, we show that the definitions of space and time in the two systems are linearly related. We deduce some novel consequences of our approach regarding faster-than-light observers and particles, “one-way” and “two-way” velocities of light, symmetry, the “group property” of inertial reference frames, length contraction and time dilatation, and the “twin paradox”. Finally, we point out a flaw in Einstein’s argument in the “Electrodynamical Part” of his paper and show that the Lorentz force formula and Einstein’s formula for transformation of field quantities are mutually consistent. We show that for faster-than-light bodies, a simple modification of Planck’s formula for mass suffices. (Except for the reference to Planck’s formula, we restrict ourselves to Physics of 1905.).

A key motivation for Universal Grammar (UG) is developmental: UG can help children acquire the linguistic knowledge that they do as quickly as they do from the data that's available to them. Some of the most fruitful recent work in language acquisition has combined ideas about different hypothesis space building blocks with domain‐general statistical learning. Statistical learning can then provide a way to help navigate the hypothesis space in order to converge on the correct hypothesis. Reinforcement learning is a principled (...) way to update the probability of a categorical option that's in competition with other categorical options. There are two prominent options for linking theory theoretical representations: the Uniformity of Theta Assignment Hypothesis (UTAH) and the relativized form of that theory, relativized UTAH. The learning strategy of Pearl and Sprouse shares the intuition with subjacency that there's a local structural anomaly when syntactic islands occur. (shrink)

What is needed today is a biologically grounded explanation of behavior, one that moves beyond the so?called mind?body problem. Yet no solution will be found by philosophers who refuse to learn about how brains and bodies work, or by neuroscientists pursuing experimental research based on outmoded or blatantly anti?biological theories. Churchland's book proposes a solution: to come by a unified theory of the mind?brain philosophers have to work together with neuroscientists. Yet Churchland's vision of a unified theory is based on (...) an assumption that, while widely held, may not adequately reflect brain functioning in the production of behavior, namely, the assumption that brain processes represent. The present paper proposes an alternative view, suggesting that patterns of neural activity do not ?represent? anything, that brains do not ?read? or ?transform? representations, and that brains do not require representations to produce goal?directed behavior. Representations are replaced by self?organizing neural processes that achieve a certain end?state of interaction between the organism and its environment in a flexible and adaptive manner. Some of the implications of this view for neuroscientific research and the philosophy of mind are outlined. (shrink)

The Curry-Howard isomorphism states an amazing correspondence between systems of formal logic as encountered in proof theory and computational calculi as found in type theory. For instance, minimal propositional logic corresponds to simply typed lambda-calculus, first-order logic corresponds to dependent types, second-order logic corresponds to polymorphic types, sequent calculus is related to explicit substitution, etc. The isomorphism has many aspects, even at the syntactic level: formulas correspond to types, proofs correspond to terms, provability corresponds to inhabitation, proof normalization corresponds to (...) term reduction, etc. But there is more to the isomorphism than this. For instance, it is an old idea---due to Brouwer, Kolmogorov, and Heyting---that a constructive proof of an implication is a procedure that transforms proofs of the antecedent into proofs of the succedent; the Curry-Howard isomorphism gives syntactic representations of such procedures. The Curry-Howard isomorphism also provides theoretical foundations for many modern proof-assistant systems (e.g. Coq). This book give an introduction to parts of proof theory and related aspects of type theory relevant for the Curry-Howard isomorphism. It can serve as an introduction to any or both of typed lambda-calculus and intuitionistic logic. Key features - The Curry-Howard Isomorphism treated as common theme - Reader-friendly introduction to two complementary subjects: Lambda-calculus and constructive logics - Thorough study of the connection between calculi and logics - Elaborate study of classical logics and control operators - Account of dialogue games for classical and intuitionistic logic - Theoretical foundations of computer-assisted reasoning · The Curry-Howard Isomorphism treated as the common theme. · Reader-friendly introduction to two complementary subjects: lambda-calculus and constructive logics · Thorough study of the connection between calculi and logics. · Elaborate study of classical logics and control operators. · Account of dialogue games for classical and intuitionistic logic. · Theoretical foundations of computer-assisted reasoning.

This volume gathers together for the first time are all the key texts in a crucial debate in modern philosophy, centered on Leibniz's famous 1695 essay, the "New System of the Nature of Substances and their Communication," in which he introduced his strikingly original theory of metaphysics. His "system" became increasingly famous and drew him into discussion and development of these ideas, both in public and in private, with a variety of thinkers, most notably the great French philosopher Pierre Bayle. (...) Woolhouse's and Francks's new English edition gives the only full representation of this debate, and will therefore be essential reading for anyone who wishes to gain a proper understanding of Leibniz's philosophy and its intelletual context. All the texts are newly translated and extensively annotated; many appear in English for the first time. (shrink)

Here we present what we believe is a novel account of what languages are, along with an axiomatically rich representation of languages and language-related data that is based on this account. We propose an account of languages as aggregates of dispositions distributed across aggregates of persons, and in doing so we address linguistic competences and the processes that realize them. This paves the way for representing additional types of language-related entities. Like demographic data of other sorts, data about languages may (...) be of use to researchers in a number of areas, including biomedical research. Data on the languages used in clinical encounters are typically included in medical records, and capture an important factor in patient-provider interactions. Like many types of patient and demographic data, data on a person’s preferred and primary languages are organized in different ways by different systems. This can be a barrier to data integration. We believe that a robust framework for representing language in general and preferred and primary language in particular – which has been lacking in ontologies thus far – can promote more successful integration of language-related data from disparate data sources.

John Heil’s new book ranges over many of the major topics in metaphysics, including substance, properties, causation, space, time, parts and wholes, modality, essence, agency, and consciousness. It has interesting things to say about all of the issues it discusses, but there are three topics that are especially prominent in the book, and which help to organize the discussion. These all flow from the differences between our everyday, commonsense understanding of reality and the representations that are offered by science.

Repetition priming of object identification refers to the phenomenon whereby experience with an object induces systematic changes in subsequent processing of that same object. This data-driven form of priming is distinct from conceptually-driven priming. To date, considerable controversy exists about whether data-driven priming reflects facilitation in perceptual processing or mediation by preexisting object representations. The present study concerned priming of recognizing familiar and unfamiliar faces and how this priming is influenced by face inversion, which interferes with perceptual face processing. (...) Perceptual and representation-based loci conjointly contributed to priming; the perceptual locus was operative similarly for familiar and unfamiliar faces, whereas the representation-based locus was only invoked for familiar faces and resulted in a response-time reduction triple the magnitude of that from the perceptual locus. The results constrain theoretical accounts of data-driven priming by indicating that improved identification can result from the combination of perceptual and representation-based facilitation.

Learning to recognize visual objects from examples requires the ability to find meaningful patterns in spaces of very high dimensionality. We present a method for dimensionality reduction which effectively biases the learning system by combining multiple constraints via the use of class labels. The use of extensive class labels steers the resulting lowdimensional representation to become invariant to those directions of variation in the input space that are irrelevant to classification; this is done merely by making class labels independent of (...) these directions. We also show that prior knowledge of the proper dimensionality of the target representation can be imposed by training a multi-layer bottleneck network. Computational experiments involving non-trivial categorization of parameterized fractal images and of human faces indicate that the low-dimensional representation extracted by our method leads to improved generalization in the learned tasks and is likely to preserve the topology of the original space.

Objectives: Medical decision support and other intelligent applications in the life sciences depend on increasing amounts of digital information. Knowledge bases as well as formal ontologies are being used to organize biomedical knowledge and data. However, these two kinds of artefacts are not always clearly distinguished. Whereas the popular RDF(S) standard provides an intuitive triple-based representation, it is semantically weak. Description logics based ontology languages like OWL-DL carry a clear-cut semantics, but they are computationally expensive, and they are often misinterpreted (...) to encode all kinds of statements, including those which are not ontological. Method: We distinguish four kinds of statements needed to comprehensively represent domain knowledge: universal statements, terminological statements, statements about particulars and contingent statements. We argue that the task of formal ontologies is solely to represent universal statements, while the non-ontological kinds of statements can nevertheless be connected with ontological representations. To illustrate these four types of representations, we use a running example from parasitology. Results: We finally formulate recommendations for semantically adequate ontologies that can efficiently be used as a stable framework for more context-dependent biomedical knowledge representation and reasoning applications like clinical decision support systems.

I compare two different arguments for the importance of bringing new voices into science: arguments for increasing the representation of women, and arguments for the inclusion of the public, or for “citizen science”. I suggest that in each case, diversifying science can improve the quality of scientific results in three distinct ways: epistemically, ethically, and politically. In the first two respects, the mechanisms are essentially the same. In the third respect, the mechanisms are importantly different. Though this might appear to (...) suggest a broad similarity between the cases, I show that the analysis reveals an important respect in which efforts to include the public are more complex. With citizen science programs, unlike with efforts to bring more women into science, the three types of improvement are often in conflict with one another: improvements along one dimension may come at a cost on another dimension, suggesting difficult trade-offs may need to be made.

Is understanding subject to a factivity constraint? That is, must the agent’s representation of some subject matter be accurate in order for her to understand that subject matter? ‘No’, I argue in this paper. As an alternative, I formulate a novel manipulationist account of understanding. Rather than correctly representing, understanding, on this account, is a matter of being able to manipulate a representation of the world to satisfy contextually salient interests. This account of understanding is preferable to factivism, I argue, (...) mainly for simplicity reasons. While it explains the intuitive data about understanding as successfully as factivist accounts, it is simpler by virtue of reducing the value truth bestows on understanding to that of usability.

THE DOUBLE INVERSION - THE CONCEPT OF FETISHISM IN THE CRITIQUE OF POLITICAL ECONOMYKarl Marx’s critical analysis of ‘the secret of the fetishism of commodities’ – according to which the universal domination of the commodity form makes social relations appear in the form of relations between things – is today widely regarded as a central element of the critique of political economy. The concept of fetishism was generally neglected until in the 1920’s, and the debates around this concept did not (...) really take off until the 1960’s. Since then, there have essentially been two predominant interpretations of Marx’s concept of fetishism: on the one hand those who regards fetishism as an ideological phenomenon, as something that has to do with the way in which social reality is represented for and in the social agents. On the other hand there are those who insists that fetishism refers to a certain displacement or inversion at the level of social practice itself, and not its ideological representation. In this article, I review these conflicting readings in the light of a close reading of Marx’s use of the term fetish in all of his writings from the Grundrisse onwards. I argue that Marx used this term to refer to an ideological phenomenon, and that he was right in doing so. I also point out that this does not entail subscribing to a naïve view of ideology as false consciousness or class manipulation that can be abolished by enlightenment and criticism. (shrink)

Background: In Switzerland, non-medical right-to-die organisations such as Exit Deutsche Schweiz and Dignitas offer suicide assistance to members suffering from incurable diseases. Objectives: First, to determine whether differences exist between the members who received assistance in suicide from Exit Deutsche Schweiz and Dignitas. Second, to investigate whether the practices of Exit Deutsche Schweiz have changed since the 1990s. Methods: This study analysed all cases of assisted suicide facilitated by Exit Deutsche Schweiz (E) and Dignitas (D) between 2001 and 2004 and (...) investigated by the University of Zurich’s Institute of Legal Medicine (E: n = 147; D: n = 274, total: 421). Furthermore, data from the Exit Deutsche Schweiz study which investigated all cases of assisted suicide during the period 1990–2000 (n = 149) were compared with the data of the present study. Results: More women than men were assisted in both organisations (D: 64%; E: 65%). Dignitas provided more assistance to non-residents (D: 91%; E: 3%; p = 0.000), younger persons (mean age in years (SD): D: 64.5 (14.1); E: 76.6 (13.3); p = 0.001), and people suffering from fatal diseases such as multiple sclerosis and amyotrophic lateral sclerosis (D: 79%; E: 67%; p = 0.013). Lethal medications were more often taken orally in cases assisted by Dignitas (D: 91%; E: 76%; p = 0.000). The number of women and the proportion of older people suffering from non-fatal diseases among suicides assisted by Exit Deutsche Schweiz has increased since the 1990s (women: 52% to 65%, p = 0.031; mean age in years (SD): 69.3 (17.0) to 76.9 (13.3), p = 0.000), non-fatal diseases: 22% to 34%, p = 0.026). Conclusions: Weariness of life rather than a fatal or hopeless medical condition may be a more common reason for older members of Exit Deutsche Schweiz to commit suicide. The strong over-representation of women in both Exit Deutsche Schweiz and Dignitas suicides is an important phenomenon so far largely overlooked and in need of further study. (shrink)

BACKGROUND -/- The need for detailed description and modeling of cells drives the continuous generation of large and diverse datasets. Unfortunately, there exists no systematic and comprehensive way to organize these datasets and their information. CELDA (Cell: Expression, Localization, Development, Anatomy) is a novel ontology for the association of primary experimental data and derived knowledge to various types of cells of organisms. -/- RESULTS -/- CELDA is a structure that can help to categorize cell types based on species, anatomical localization, (...) subcellular structures, developmental stages and origin. It targets cells in vitro as well as in vivo. Instead of developing a novel ontology from scratch, we carefully designed CELDA in such a way that existing ontologies were integrated as much as possible, and only minimal extensions were performed to cover those classes and areas not present in any existing model. Currently, ten existing ontologies and models are linked to CELDA through the top-level ontology BioTop. Together with 15.439 newly created classes, CELDA contains more than 196.000 classes and 233.670 relationship axioms. CELDA is primarily used as a representational framework for modeling, analyzing and comparing cells within and across species in CellFinder, a web based data repository on cells (http://cellfinder.org). -/- CONCLUSIONS -/- CELDA can semantically link diverse types of information about cell types. It has been integrated within the research platform CellFinder, where it exemplarily relates cell types from liver and kidney during development on the one hand and anatomical locations in humans on the other, integrating information on all spatial and temporal stages. CELDA is available from the CellFinder website: http://cellfinder.org/about/ontology. (shrink)

Some regularities enjoy only an attenuated existence in a body of training data. These are regularities whose statistical visibility depends on some systematic recoding of the data. The space of possible recodings is, however, infinitely large type-2 problems. they are standardly solved! This presents a puzzle. How, given the statistical intractability of these type-2 cases, does nature turn the trick? One answer, which we do not pursue, is to suppose that evolution gifts us with exactly the right set of recoding (...) biases so as to reduce specific type-2 problems to (tractable) type-1 mappings. Such a heavy-duty nativism is no doubt sometimes plausible. But we believe there are other, more general mechanisms also at work. Such mechanisms provide general (not task-specific) strategies for managing problems of type-2 complexity. Several such mechanisms are investigated. At the heart of each is a fundamental ploy representational redescription language and culture – may themselves be viewed as adaptations enabling this representation/computation trade-off to be pursued on an even grander scale.

According to ‘direct social perception’ (DSP) accounts of social cognition, perception may be ‘smart’ enough on its own to inform us about other people’s emotions. Some DSP advocates suggest that ‘smart’ social perception should be conceived along ‘enactive’ lines. In this paper, I suggest that DSP needs social perception to have representational content. This seems in tension with the main versions of enactivism, which deny that perception is representational. I thus present the following challenge to ‘enactive’ versions of DSP: either (...) they show how perception can have the requisite smartness without representational content, which I doubt that they can, or they embrace the orthodox idea that perceptual experiences have representational contents. I also suggest that DSP defenders, whether or not they want to be enactivists, can cheerfully accept the latter idea. (shrink)

In this paper we review some properties of fuzzy observables, mainly as realized by commutative positive operator valued measures. In this context we discuss two representation theorems for commutative positive operator valued measures in terms of projection valued measures and describe, in some detail, the general notion of fuzzification.
