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)

We analyze the meaning of the violation of the marginal probability law for situations of correlation measurements where entanglement is identified. We show that for quantum theory applied to the cognitive realm such a violation does not lead to the type of problems commonly believed to occur in situations of quantum theory applied to the physical realm. We briefly situate our quantum approach for modeling concepts and their combinations with respect to the notions of “extension” and “intension” in theories of (...) meaning, and in existing concept theories.

Consider the concept combination ‘pet human’. In word association experiments, human subjects produce the associate ‘slave’ in relation to this combination. The striking aspect of this associate is that it is not produced as an associate of ‘pet’, or ‘human’ in isolation. In other words, the associate ‘slave’ seems to be emergent. Such emergent associations sometimes have a creative character and cognitive science is largely silent about how we produce them. Departing from a dimensional model of human (...) conceptual space, this article will explore concept combinations, and will argue that emergent associations are a result of abductive reasoning within conceptual space, that is, below the symbolic level of cognition. A tensor-based approach is used to model concept combinations allowing such combinations to be formalized as interacting quantum systems. Free association norm data is used to motivate the underlying basis of the conceptual space. It is shown by analogy how some concept combinations may behave like quantum-entangled particles. Two methods of analysis were presented for empirically validating the presence of non-separable concept combinations in human cognition. One method is based on quantum theory and another based on comparing a joint probability distribution with another distribution based on a separability assumption using a chi-square goodness-of-fit test. Although these methods were inconclusive in relation to an empirical study of bi-ambiguous concept combinations, avenues for further refinement of these methods are identified. (shrink)

When people combine concepts these are often characterised as “hybrid”, “impossible”, or “humorous”. However, when simply considering them in terms of extensional logic, the novel concepts understood as a conjunctive concept will often lack meaning having an empty extension (consider “a tooth that is a chair”, “a pet flower”, etc.). Still, people use different strategies to produce new non-empty concepts: additive or integrative combination of features, alignment of features, instantiation, etc. All these strategies involve the ability to deal (...) with conflicting attributes and the creation of new (combinations of) properties. We here consider in particular the case where a Head concept has superior ‘asymmetric’ control over steering the resulting concept combination (or hybridisation) with a Modifier concept. Specifically, we propose a dialogical approach to concept combination and discuss an implementation based on axiom weakening, which models the cognitive and logical mechanics of this asymmetric form of hybridisation.

Understanding novel phrases (e.g. upside‐down daisy) and classifying objects in categories named by phrases ought to have common properties, but you'd never know it from current theories. The best candidate for both jobs is the Theory Theory, but it faces difficulties when theories are impoverished. A potential solution is a dual approach that couples theories (representations‐about categories) with fixed mentalese expressions (representations‐of categories). Both representations combine information in parallel when understanding phrases. Although there are objections to the notion that theories (...) can combine, some of them lose their force when applied to a suitable dual model. (shrink)

This article presents a detailed formal approach to concepts and concept combination. Sense generation is a competence‐level theory that attempts to respect constraints from the various cognitive sciences, and postulates “quasi‐classical” conceptual structures where attributes receive only one value (but are defeasible and so do not represent necessary and sufficient conditions on category membership) and where classification is binary (but explicitly context‐sensitive). It is also argued that any general theory of concepts must account for “privative” combinations (e.g., stone (...) lion, fake gun, apparent friend) as extreme test‐cases of representational and classificatory flexibility. The approach presented therefore provides a treatment of these combinations. The approach differentiates between the “lexical concept” (the stable information represented in a mental lexicon) which acts as a base from which the various “senses” (flexible contents associated with words and phrases in context, and used in classification) are “generated.” Generation allows nonmonotonicity, so that in different circumstances, different attributes may be defeated or modified. Classification is treated as relative to the perspective adopted, so that a classification acceptable from one perspective may be unacceptable from another, without contradiction. The result is a view that assumes bottom‐up priority in concept combination, where the range of senses generated by bottom‐up rules of combination is tempered by pragmatic‐communicative constraints on classification. An account of the representational and classification behavior of privative combinations is outlined, and the article concludes with a discussion of some of the implications of the approach.

We introduce a family of operators to combine Description Logic concepts. They aim to characterise complex concepts that apply to instances that satisfy \enough" of the concept descriptions given. For instance, an individual might not have any tusks, but still be considered an elephant. To formalise the meaning of "enough", the operators take a list of weighted concepts as arguments, and a certain threshold to be met. We commence a study of the formal properties of these operators, and study (...) some variations. The intended applications concern the representation of cognitive aspects of classi cation tasks: the interdependencies among the attributes that de ne a concept, the prototype of a concept, and the typicality of the instances.

The cognitive anthropological approach has provided a powerful means of beginning to understand religious representations. I suggest that two extant approaches, despite their general plausibility, may not accurately characterise the detailed nature of those representations. A major source of this inaccuracy lies in the characterisation of negation of ontological properties, which gives rise to broader questions about their ontological determinacy and counter-intuitiveness. I suggest that a more plausible account may be forthcoming by allowing a more complex approach to the representations, (...) deriving from understanding their nature as concept combinations. Such an account also suggests an alternative approach to the role of deference in religious representations. In sum, the empirical and theoretical implications of a more fine-grained analysis of religious representations suggest a vindication of the cognitive anthropology approach to integrating culture and cognition.

We propose a theory for modeling concepts that uses the state-context-property theory (SCOP), a generalization of the quantum formalism, whose basic notions are states, contexts and properties. This theory enables us to incorporate context into the mathematical structure used to describe a concept, and thereby model how context influences the typicality of a single exemplar and the applicability of a single property of a concept. We introduce the notion `state of a concept' to account for this contextual (...) influence, and show that the structure of the set of contexts and of the set of properties of a concept is a complete orthocomplemented lattice. The structural study in this article is a preparation for a numerical mathematical theory of concepts in the Hilbert space of quantum mechanics that allows the description of the combination of concepts. (shrink)

The sets of contexts and properties of a concept are embedded in the complex Hilbert space of quantum mechanics. States are unit vectors or density operators, and contexts and properties are orthogonal projections. The way calculations are done in Hilbert space makes it possible to model how context influences the state of a concept. Moreover, a solution to the combination of concepts is proposed. Using the tensor product, a procedure for describing combined concepts is elaborated, providing a (...) natural solution to the pet fish problem. This procedure allows the modeling of an arbitrary number of combined concepts. By way of example, a model for a simple sentence containing a subject, a predicate and an object, is presented.

Embodiment approaches to cognition and emotion have put forth the idea that the way we think and talk about affective events often recruits spatial information that stems, to some extent, from our bodily experiences. For example, metaphorical expressions such as “being someone’s right hand” or “leaving something bad behind” convey affectivity associated with the lateral and sagittal dimensions of space. Action tendencies associated with affect such as the directional fluency of hand movements (dominant right hand-side – positive; non-dominant left hand-side (...) – negative) and approach-avoidance behaviors (forward – positive; backwards – negative) might be mechanisms supporting such associations. Against this background, experimental research has investigated whether positive and negative words are freely allocated into space (e.g., close or far from one’s body) or resonate with congruent (vs. incongruent) predefined manual actions usually performed by joysticks or button presses (e.g., positive - right; negative - left, or vice versa). However, to date, it is unclear how the processing of affective concepts resonate with directional actions of the whole body that are performed freely within a context enabling lateral and sagittal movements simultaneously. Accordingly, 67 right-handed participants were to freely step on an 8-response pad (front, back, right, left, front-right, front-left, back-right, or back-left) after being presented in front of them valence-laden personal life-events submitted before the task (e.g., words or sentences such as “graduation” or “birth of a child”). The most revealing finding of this study indicates that approach-avoidance behaviors and space-valence associations across laterality are interwoven during whole body step actions: Positive events induced steps highly biased to front-right whereas negative events induced steps highly biased to back-left.

Conceptual combination performs a fundamental role in creating the broad range of compound phrases utilised in everyday language. This article provides a novel probabilistic framework for assessing whether the semantics of conceptual combinations are compositional, and so can be considered as a function of the semantics of the constituent concepts, or not. While the systematicity and productivity of language provide a strong argument in favor of assuming compositionality, this very assumption is still regularly questioned in both cognitive science and (...) philosophy. Additionally, the principle of semantic compositionality is underspecifi ed, which means that notions of both "strong" and "weak" compositionality appear in the literature. Rather than adjudicating between different grades of compositionality, the framework presented here contributes formal methods for determining a clear dividing line between compositional and non-compositional semantics. In addition, we suggest that the distinction between these is contextually sensitive. Compositionality is equated with a joint probability distribution modeling how the constituent concepts in the combination are interpreted. Marginal selectivity is introduced as a pivotal probabilistic constraint for the application of the Bell/CH and CHSH systems of inequalities. Non-compositionality is equated with a failure of marginal selectivity, or violation of either system of inequalities in the presence of marginal selectivity. This means that the conceptual combination cannot be modeled in a joint probability distribution, the variables of which correspond to how the constituent concepts are being interpreted. The formal analysis methods are demonstrated by applying them to an empirical illustration of twenty-four non-lexicalised conceptual combinations. (shrink)

In the metabolic control theory, the control coefficient is a key parameter in quantifying the sensitivity of the flux towards an infinitesimal variation of enzyme activity. This concept does not apply just as it is for variations of enzyme concentrations whenever there is spatial, energy or resources limitations in the cell. Due to constraint on total enzyme concentration, the variation of concentration of any given enzyme may affect the concentrations of other enzymes. To take into account these correlations between (...) enzyme concentrations, we propose the concept of "combined response coefficient". Its definition is similar to that of the control coefficient, but its mathematical expression is different. Its range of variation is from – + 1, the null value corresponding to optimum enzyme concentration, i.e. to concentrations that maximise the flux, and the negative values to concentrations beyond the optimum value. A summation property could be derived using a simple weighting of the combined response coefficients, the sum of the weighed coefficient being 0. (shrink)

Aerts et al. provide a valuable model to capture the interactive nature of conceptual combination in conjunctions and disjunctions. The commentary provides a brief review of the interpretation of these interactions that has been offered in the literature, and argues for a closer link between the more traditional account in terms of concept intensions, and the parameters that emerge from the fitting of the Quantum Probability model.

We analyze different aspects of our quantum modeling approach of human concepts and, more specifically, focus on the quantum effects of contextuality, interference, entanglement, and emergence, illustrating how each of them makes its appearance in specific situations of the dynamics of human concepts and their combinations. We point out the relation of our approach, which is based on an ontology of a concept as an entity in a state changing under influence of a context, with the main traditional (...) class='Hi'>concept theories, that is, prototype theory, exemplar theory, and theory theory. We ponder about the question why quantum theory performs so well in its modeling of human concepts, and we shed light on this question by analyzing the role of complex amplitudes, showing how they allow to describe interference in the statistics of measurement outcomes, while in the traditional theories statistics of outcomes originates in classical probability weights, without the possibility of interference. The relevance of complex numbers, the appearance of entanglement, and the role of Fock space in explaining contextual emergence, all as unique features of the quantum modeling, are explicitly revealed in this article by analyzing human concepts and their dynamics.

In this thesis I argue for the following theory: constitutive Russellian phenomenal bonding panpsychism. To do so I do three main things: 1) I argue for Russellian panpsychism. 2) I argue for phenomenal bonding panpsychism. 3) I defend the resultant phenomenal bonding panpsychist model. The importance of arguing for such a theory is that if it can be made to be viable, then it is proposed to be the most promising theory of the place of consciousness within nature. This is (...) because constitutive Russellian panpsychism has all the theoretical virtues of physicalism and dualism but does not face the problems they do. The combination problem, however, is the most significant problem for the Russellian panpsychist, and, hence, in order to show the viability of the theory I address this problem. Moreover, I present a novel ”mereological argument’ for panpsychism which makes it necessary that the Russellian panpsychist addresses the combination problem. The focus of this thesis is therefore addressing this problem. I argue that the combination problem can indeed be solved. To do so I argue for the phenomenal bonding solution proposed by Goff. I argue that this solution works and that we can form a positive concept of the phenomenal bonding relation. This forces the panpsychist to make sense of how experiencing subjects can be proper parts of other experiencing subjects. I then argue that this can indeed be made sense of and show that we can indeed be composite subjects made of other subjects. To show that we can be subjects made up of other subjects I defend this proposal from various objections from throughout the literature. All these objections can be responded to by the constitutive Russellian phenomenal bonding panpsychist. Ultimately this leaves us with a novel and interesting account of what conscious subjects are, and what the material world is: they are both composite entities made wholly of conscious matter.

The question of how concepts are formed was central for positivist and operationalist philosophers concerned to root scientific thought directly in experience. Although the positivist program has been abandoned, the current interest in the philosophy of scientific discovery shows the need for a theory of conceptual development. This paper offers a theory of how new concepts can arise, not by abstraction from experience or by definition, but by conceptual combination. Such combination produces a new concept as a (...) non-linear, non-definitional amalgam of existing concepts. After proposing rules intended to account for a variety of mundane cases of conceptual combination, the paper presents several illustrations of how scientific concepts have arisen through combination.

There seems to be an interesting difference between judging someone to be good and judging them to be kind. Both judgements are typically positive, but the latter seems to offer more description of the person: we get a slightly more specific sense of what they are like. Very general evaluative concepts are referred to as thin concepts, whilst more specific ones are termed thick concepts. Examples of the former include good, bad, right and wrong, whilst there are countless examples of (...) the latter: brave, rude, gracious, wicked, sympathetic, mean. Marking this distinction opens up some interesting questions. How do the descriptive and evaluative elements of thick concepts combine? Are these elements separable in the first place? Is there a sharp division between thin and thick concepts? Can we mark interesting further distinctions between how thick ethical concepts work and how their aesthetic and epistemic counterparts work? How, if at all, are thick and thin concepts related to reasons and action?.These questions, and others, touch on some of the deepest philosophical issues about the evaluative and normative. They force us to think hard about the place of the evaluative in a (seemingly) nonevaluative world, and they also raise fascinating issues about how language works.This volume of twelve papers explores the phenomenon of thin and thick concepts.

In 1995 the People's Republic of China passed a controversial Eugenics Law, which, after a torrent of international criticism, was euphemistically renamed the Maternal and Infant Health Law. Aimed at "the implementation of premarital medical checkups" to ensure that neither partner has any hereditary, venereal, reproductive, or mental disorders, the ordinance implies that those deemed "unsuitable for reproduction" should undergo sterilization or abortion or remain celibate in order to prevent "inferior births." Using this recent statute as a springboard, Frank Dikötter (...) explores the contexts and history of eugenics in both Communist China and Taiwan. Dikötter shows how beginning in Late Imperial China, Western eugenics was imported and combined with existing fears of cultural, racial, or biological degeneration in Chinese society, leading to government regulation of sexual reproduction. _Imperfect Conceptions_ is a revealing look at the cultural history of medical explanations of birth defects that demonstrates how Chinese assumptions about the relationship of the individual to society form the very core of their attitudes toward procreation. Dikötter explains the patrilineal model of descent, where a person is viewed as the culmination of his or her ancestors and is held responsible for the health of all future generations. By this logic, a pregnant woman's behavior and attitude directly influence the well-being of her baby, and a deformed or retarded child reflects a moral failing on the part of the parents. Dikötter also shows how the holistic medicine practiced in China blurs any distinction between individual and environment so that people are held responsible for illness. Drawing on cultural, social, economic, and political approaches, Dikötter goes beyond a simple authoritarian model to provide a more complex view of eugenic policy, showing how a variety of voices including those of popular journalists, social reformers, medical writers, sex educators, university professors, and politicians all disseminate information that supports rather than questions the state's program. _Imperfect Conceptions_ reveals how Chinese cultural currents--fear and fascination with the deviant and the urge to draw clear boundaries between the normal and the abnormal--have combined with medical discourse to form a program of eugenics that is viewed with alarm by the rest of the world.

A disjunctivist conception of acting for reasons is introduced by way of showing that a view of acting for reasons must give a place to knowledge. Two principal claims are made. 1. This conception has a rôle analogous to that of the disjunctive conception that John McDowell recommends in thinking about perception; and when the two disjunctivist conceptions are treated as counterparts, they can be shown to have work to do in combination. 2. This conception of acting for reasons (...) safeguards the connection between considerations that move us to act in particular ways and considerations that favour our acting in particular ways.

In ethics, aesthetics and increasingly in epistemology, a distinction is drawn between thick and thin evaluative concepts. A common characterisation of the distinction is that thin concepts have only evaluative content, whereas thick concepts combine evaluative and descriptive content. Because of this combination, it is again commonly thought that thick concepts have various distinctive powers including the power to undermine the distinction between fact and value. This paper discusses the accuracy of this view of the thick concepts debate, as (...) well as assessing the prospects for a thick concepts argument against the fact value distinction, while introducing the three main philosophical positions on the nature of thick concepts.

InHow the West Came to Rule, Alexander Anievas and Kerem Nişancıoğlu offer an alternative to both Political Marxism and world-systems analysis by going beyond the nation-state as the unit of analysis in the former and the marginalisation of articulation and combination between modes of production in the latter. Their account also gives more room to non-European actors neglected in other interpretations of the rise of the West. However, I argue that their argument is much closer toWSAand that their critique (...) of Wallerstein regarding Eurocentrism, the origins of capitalism and the role of wage labour in the capitalist world-system is problematic.

Panpsychism, an increasingly popular competitor to physicalism as a theory of mind, faces a famous difficulty, the ‘combination problem’. This is the difficulty of understanding the composition of a conscious mind by parts which are themselves taken to be phenomenally qualitied.

After homing in on the (...) genuine worries, I identify some disputable assumptions that underlie them. Doing away with these assumptions allows us to make a start on a working conception of phenomenal combination. (shrink)

The reconciliation of theories of concepts based on prototypes, exemplars, and theory-like structures is a longstanding problem in cognitive science. In response to this problem, researchers have recently tended to adopt either hybrid theories that combine various kinds of representational structure, or eliminative theories that replace concepts with a more finely grained taxonomy of mental representations. In this paper, we describe an alternative approach involving a single class of mental representations called “semantic pointers.” Semantic pointers are symbol-like representations that result (...) from the compression and recursive binding of perceptual, lexical, and motor representations, effectively integrating traditional connectionist and symbolic approaches. We present a computational model using semantic pointers that replicates experimental data from categorization studies involving each prior paradigm. We argue that a framework involving semantic pointers can provide a unified account of conceptual phenomena, and we compare our framework to existing alternatives in accounting for the scope, content, recursive combination, and neural implementation of concepts.

The fields treated range from mathematics to virology and genetics, from nuclear physics to psychology, (...) from technology to present-day neural engineering.

Statistical topic models provide a general data - driven framework for automated discovery of high-level knowledge from large collections of text documents. Although topic models can potentially discover a broad range of themes in a data set, the interpretability of the learned topics is not always ideal. Human-defined concepts, however, tend to be semantically richer due to careful selection of words that define the concepts, but they may not span the themes in a data set exhaustively. In this study, we (...) review a new probabilistic framework for combining a hierarchy of human-defined semantic concepts with a statistical topic model to seek the best of both worlds. Results indicate that this combination leads to systematic improvements in generalization performance as well as enabling new techniques for inferring and visualizing the content of a document.

Concepts are the constituents of thoughts. Therefore, concepts are vital to any theory of cognition. However, despite their widely accepted importance, there is little consensus about the nature and origin of concepts. Thanks to the work of Lawrence Barsalou, Jesse Prinz and others concept empiricism has been gaining momentum within the philosophy and psychology literature. Concept empiricism maintains that all concepts are copies, or combinations of copies, of perceptual representations—that is, all concepts are couched in the codes of (...) perceptual representation systems. It is widely agreed that any satisfactory theory of concepts must account for how concepts semantically compose (the compositionality requirement) and explain how their intentional content is determined (the content determination requirement). In this paper, I argue that concept empiricism has serious problems satisfying these two requirements. Therefore, although stored perceptual representations may facilitate some traditionally conceptual tasks, concepts should not be identified with copies of perceptual representations. (shrink)

Concepts and Cases in Nursing Ethics maps the ethical landscape of contemporary nursing. The book is the product of a collaboration between philosopher-ethicist Michael Yeo, nurse-ethicist Anne Moorhouse, and six representatives of various areas of professional nursing. It thus combines philosophical and ethical analysis with nursing knowledge and experience in a manner that is both understandable and relevant. The book is organized around six main concepts in nursing ethics: beneficence, autonomy, confidentiality, truth-telling, justice, and integrity. A chapter is devoted to (...) the elucidation of each of these concepts. In each chapter, historical background and conceptual analysis are supplemented by case studies that exemplify issues and show how the concept applies in nursing practice. In this new edition, the materials in each chapter have been updated to reflect recent developments in nursing and more generally in health care. In addition, a totally new chapter on ethical theory has been added. Complete with bibliographies and study questions for further analysis of cases, this book is ideally suited for textbook use. It will help both practitioners and students to deal better with the clinical problems and issues that are encountered in the field. However, it's simple prose and clear exposition of complex issues will make Concepts and Cases in Nursing Ethics attractive to anyone concerned about health care. (shrink)

It has become common to distinguish between two kinds of ethical concepts: thick and thin ones. Bernard Williams, who coined the terms, explains that thick concepts such as “coward, lie, brutality, gratitude and so forth” are marked by having greater empirical content than thin ones. They are both action-guiding and world-guided: -/- If a concept of this kind applies, this often provides someone with a reason for action… At the same time, their application is guided by the world. A (...) concept of this sort may be rightly or wrongly applied, and people who have acquired it can agree that it applies or fails to apply to some new situation. -/- Thin concepts are concepts such as good and bad, right and wrong, obligation and duty. Judgments applying thick concepts have been seen as lending support to the possibility of explaining moral knowledge, and objectivity in ethics. It appears that due to their empirical content – their world-guidedness – judgments employing thick concepts can be true or false, depending on whether they get the worldly facts right. In addition they provide reasons for action – they are action-guiding – and thus may provide the starting point of a realist account of practical reasons: the view that reasons are facts and whether or not a person has a reason to act does not (normally) depend on her attitudes. The cruelty of an action is a reason not to perform it or to prevent it; that an action is kind is a reason in its favour. Of course these remarks aren’t conclusive – far from it. But even so, some non-cognitivists may regard them as completely wrongheaded, and so does Bernard Williams even though he is not a non-cognitivist. However, he believes that having a practical reason does depend on a person’s attitudes and motives. A certain worry about thick concepts will make clear what the problem is. It has most expressly been raised by Simon Blackburn, who sees it as undermining even the most superficial plausibility of moral cognitivism, as well as the claim that the properties picked out by thick concepts provide reasons. While we may readily accept that the kindness of an action or the fact that it is required by justice is a reason to perform it, there are many thick concepts whose action-guiding role we would reject. Some derogatory – e.g., racist or sexist - words express thick concepts too, Blackburn notes. And surely there are no racist or sexist truths. Furthermore there are concepts that some people use evaluatively (like chaste or obscene), but many of us do not regard the propositions in which those concepts feature as even prima facie reason giving. In raising these points, Blackburn claims that it is morally objectionable to regard the facts asserted in propositions which employ thick concepts as action-guiding because it leads to “a conservative and ultimately self-serving complacency.” As he sees it, the problem is that if we believe that the correct application of thick concepts yields evaluative truths and that evaluative truths state reasons for actions, we seem to be committed to accepting that some people are, say, fat, derog., and therefore to be ridiculed, and that there is at least a pro tanto reason to lead a chaste life, or feel affection towards cute women. Therefore, the view that all evaluative properties provide reasons for action or for attitudes such as admiration, affection or (dis)approval must be rejected. I will call this worry henceforth Blackburn’s challenge. The challenge is that understanding judgments employing thick concepts as expressing evaluative truths and providing reasons for actions or for attitudes leads to a morally unacceptable view. Blackburn suggests instead that we should separate the conditions for applying thick concepts and the reasons that we have in virtue of the concept applying. She may be cute, yes, but that is not a reason for “admiration and arousal.” -/- …it is morally vital that we proceed by splitting the input from the output in such a case. By refusing to split we fail to open an essential specifically normative dimension of criticism. -/- According to Blackburn, the meaning of thick concepts is made up of two distinct and in principle separable components: a descriptive one and the expression of an attitude. The truth-aptness and cognitive appearance of judgments employing thick concepts is explained by the descriptive component alone. Blackburn writes “[w]e get nothing but detachable and flexible attitudes, coupled with delineations of traits of character or action”. I will call this reply to Blackburn’s challenge the separability thesis. I agree with Blackburn that any account of thick concepts has to face and answer the challenge that he poses. In this paper, I will focus on one reply to the challenge which denies separability, namely Bernard Williams’s. Williams answers Blackburn’s challenge, while holding on to a cognitivist understanding of thick concepts. But his particular brand of cognitivism is peculiar: Williams rejects the separability thesis, and claims that correct applications of thick concepts yield evaluative (and not just descriptive) knowledge. But this is a special kind of knowledge. It is confined to a local community. The members of a community which uses certain thick concepts may have reasons to act accordingly, but the non-members do not. And even the reasons of members remain a little fragile: they may not want to continue using their concepts upon thorough reflection. The local knowledge view allows Williams to answer Blackburn’s challenge, because even though thick concepts are evaluative concepts and their application can yield evaluative knowledge, no one who isn’t a member of the relevant community has reason to be guided by the concept. Complementing a cognitivist view of thick concepts with reasons internalism allows Williams to answer the challenge. My aim in this paper is to show that Williams’s position is, despite its initial attraction, untenable. In particular, I am going to show why the internal reasons view is incompatible with Williams’s own understanding of thick concepts. My modest result is that the internalist view of reasons does not help to answer Blackburn’s challenge. My aim in this paper is not to answer the challenge but, rather, to explore the possibility of developing Williams’s attenuated version of cognitivism, and the possibility of combining it with reasons internalism.

Do we learn anything from social anthropology done in more familiar settings, such as England?

In his 1763 Prize Essay, Kant is thought to endorse a version of formalism on which mathematical concepts need not apply to extramental objects. Against this reading, I argue that the Prize Essay has sufficient resources to explain how the objective reference of mathematical concepts is secured. This account of mathematical concepts’ objective reference employs material from Wolffian philosophy. On my reading, Kant's 1763 view still falls short of his Critical view in that it does not explain the universal, unconditional (...) applicability of mathematical concepts. (shrink)

Dynamic conceptual reframing represents a crucial mechanism employed by humans, and partially by other animal species, to generate novel knowledge used to solve complex goals. In this talk, I will present a reasoning framework for knowledge invention and creative problem solving exploiting TCL: a non-monotonic extension of a Description Logic (DL) of typicality able to combine prototypical (commonsense) descriptions of concepts in a human-like fashion [1]. The proposed approach has been tested both in the task of goal-driven concept invention (...) [2,3] and has additionally applied within the context of serendipity-based recommendation systems [4]. I will present the obtained results, the lessons learned, and the road ahead of this research path. -/- . (shrink)

The traditional conception of response-dependence isinadequate because it cannot account for all intuitivecases of response-dependence. In particular, it is unableto account for the response-dependence of (aesthetic, moral, epistemic ...) values. I therefore propose tosupplement the traditional conception with an alternativeone. My claim is that only a combination of the twoconceptions is able to account for all intuitivecases of response-dependence.

Cultures of Uneven and Combined Development seeks to explore and develop Leon Trotsky's concept of uneven and combined development. In particular, it aims to adapt the political and historical analysis which originated in Trotsky's Russia for use within the contemporary field of world literature. As such, it draws together the work of scholars from both the field of international relations and the field of literature and the arts. This collection will therefore be of particular interest to anyone who is (...) interested in new ways of understanding world literary texts, or interested in new ways of applying Trotsky's revolutionary politics to the contemporary world order.

Although cognitive scientists have learned a lot about concepts, their findings have yet to be organized in a coherent theoretical framework. In addition, after twenty years of controversy, there is little sign that philosophers and psychologists are converging toward an agreement about the very nature of concepts.Doing without Concepts(Machery 2009) attempts to remedy this state of affairs. In this article, I review the main points and arguments developed at greater length inDoing without Concepts.

It seems to be impossible to draw metaphysical conclusions about the world merely from our concepts or our language alone. After all, our concepts alone only concern how we aim to represent the world, not how the world in fact is. In this paper I argue that this is mistaken. We can sometimes draw substantial metaphysical conclusions simply from thinking about how we represent the world. But by themselves such conclusions can be flawed if the concepts from which they are (...) drawn are themselves flawed. I propose that we can overcome these limitations by focusing on a special class of concepts: inescapable concepts. Combining arguments about what the world is like from considerations about our concepts alone, together with an argument that the relevant concepts are inescapable, leads to a novel method for metaphysics, which is broadly neo-Kantian.

This paper argues that there are two irreducibly distinct negative concepts of liberty: freedom as non-prevention, and freedom as non-coercion. Contemporary proponents of the negative view, such as Matthew Kramer and Ian Carter, have sought to develop the Hobbesian idea that freedom is essentially a matter of physical non-prevention. Accordingly, they have sought to reduce the freedom-diminishing effect of coercion to that of prevention by arguing that coercive threats function to diminish freedom by preventing people from performing certain combinations of (...) actions. Against this, this paper argues that coercion diminishes people’s freedom in ways that cannot be fully captured in terms of prevention. Focusing on two types of case, those involving coercive threats and those involving coercive preference manipulation, it argues that non-coercion and physical non-prevention are importantly different goods. It concludes that a complete negative account of liberty must draw not only on the (Hobbesian) ‘non-prevention’ strand of the negative tradition but also on its (Hayekian) ‘non-coercion’ strand.
