Why Theories of Concepts Should Not Ignore the Problem of Acquisition.

While Nyaya texts seldom address the topic of concepts directly, it is my contention that Nyaya system can accommodate a sustained notion of concepts and clarifying its parameters can help us with a debate in Nyaya epistemology of perception that has been popular in contemporary discussion of Indian philosophy. This debate focuses on the exact nature of nirvikalpaka perception and its viability within Nyaya direct realism. One of the central questions in this regard is the role of (...) class='Hi'>concepts in our perception. Using an account of concepts developed in contemporary Western philosophy by Millikan as a template I will articulate a few aspects of Nyaya theory of concepts. One of the outcomes of this undertaking will be that Nyaya theory of concept as developed here will not preclude nirvikalpaka perception. (shrink)

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.

The word ‘concept’ is sometimes used as a synonym for ‘property’, but many authors use it in a more specific sense, for example as standing for unsaturated entities whose extensions are sets and classes, for Fregean senses, or for abstract objects. Although there is no universal agreement on a definition of concepts, a viable theory of concepts has to address a number of formal issues: How to deal with counterfactual and possibly contradictory concepts, how to restrict (...) comprehension schemes in higher-order logic to avoid semantic paradoxes like the Paradox of Predication, how to nominalize concepts, and how to express similarity and typicality of concepts. The article gives a brief survey of the most important problems in concept theory and their possible solutions. (shrink)

Philosophers from Hume, Kant, and Wittgenstein to the recent realists and antirealists have sought to answer the question, What are concepts? This book provides a detailed, systematic, and accessible introduction to an original philosophical theory of concepts that Christopher Peacocke has developed in recent years to explain facts about the nature of thought, including its systematic character, its relations to truth and reference, and its normative dimension. Particular concepts are also treated within the general framework: perceptual (...) concepts, logical concepts, and the concept of belief are discussed in detail. The general theory is further applied in answering the question of how the ontology of concepts can be of use in classifying mental states, and in discussing the proper relation between philosophical and psychological theories of concepts. Finally, the theory of concepts is used to motivate a nonverificationist theory of the limits of intelligible thought. Peacocke treats content as broad rather than narrow, and his account is nonreductive and non-Quinean. Yet Peacocke also argues for an interactive relationship between philosophical and psychological theories of concepts, and he plots many connections with work in cognitive psychology. (shrink)

It has been claimed that the prototype theory of concepts supports two controversial claims in the philosophy of art: that art cannot be defined, and that the possession of a certain sort of historical narrative is a sufficient but not necessary means of determining the art status of contested works. It is argued here that two sorts of considerations undermine the thesis that prototype theory offers significant support to anti-definitionism and historical narrativism. First, there is reason to (...) think that prototype theory is as a psychological theory not the sort of view that can support philosophical theories like anti-definitionism and historical narrativism. Second, well-known objections and theoretical alternatives to prototype theory theory raise serious questions about that theory’s own credentials. (shrink)

The paper begins with an argument against eliminativism with respect to the propositional attitudes. There follows an argument that concepts are sui generis ante rem entities. A nonreductionist view of concepts and propositions is then sketched. This provides the background for a theory of concept possession, which forms the bulk of the paper. The central idea is that concept possession is to be analyzed in terms of a certain kind of pattern of reliability in one’s intuitions regarding (...) the behavior of the concept. The challenge is to find an analysis that is at once noncircular and fully general. Environmentalism, anti-individualism, holism, analyticity, etc. provide additional hurdles. The paper closes with a discussion of the theory’s implications for the Wittgenstein-Kripke puzzle about rule-following and the Benacerraf problem concerning mathematical knowledge. (shrink)

Fodor’s theory of concepts holds that the psychological capacities, beliefs or intentions which determine how we use concepts do not determine reference. Instead, causal relations of a specific kind between properties and our dispositions to token a concept are claimed to do so. Fodor does admit that there needs to be some psychological mechanisms mediating the property–concept tokening relations, but argues that they are purely accidental for reference. In contrast, I argue that the actual mechanisms that sustain (...) the reference determining concept tokening relations are necessary for reference. Fodor’s atomism is thus undermined, since in order to refer with a concept it is necessary to possess some specific psychological capacities. (shrink)

Two general principles have played a crucial role in the recent debate on concepts. On the one hand, we want to allow different subjects to have the same concepts, thus accounting for concept publicity: concepts are ‘the sort of thing that people can, and do, share’. On the other hand, a subject who finds herself in a so-called ‘Frege case’ appears to have different concepts for the same object: for instance, Lois Lane has two distinct (...) class='Hi'>concepts SUPERMAN and CLARK KENT which refer to the same person. Several theories have tried to meet both of these constraints at the same time. But should we really try to satisfy both principles? This paper will argue that the traditional project of fulfilling these two constraints has been a misguided one. Through a variation on classic identity mistake cases, I will show that our two desiderata are inconsistent: it would thus be impossible to incorporate both of them in our best theory of concepts.

Agents can think using concepts they do not fully understand. This paper investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I lay out a gauntlet of problems and desiderata with which any theory of concept mastery must cope. I use these considerations to argue against three views of concept mastery, according to which mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain (...) intuitions. None of these attitudes is either necessary or sufficient for mastery. I propose and respond to objections to my own recognition view of the conditions under which a thinker has mastery of a concept.

The Kantian idea that some judgments are synthetic even in the area of a priori judgments cannot be accepted in its original version, but a modification of the notions analytic' and 'synthetic' discovers a rational core of that idea. The new definition of 'analytic' concerns concepts and makes it possible to distinguish between analytic concepts, which are effective ways of computing recursive functions, and synthetic concepts, which either define non-recursive functions, or define recursive functions in an ineffective (...) way. To justify this claim we have to construe concepts as abstract procedures not reducible to set-theoretical entities. (shrink)

Fodor’s theory of concepts holds that the psychological mechanisms which guide us in applying concepts to objects do not determine reference; instead, causal relations of a specific kind between properties and our dispositions to token a concept are claimed to do so. Fodor does admit that there needs to be some psychological mechanism mediating the property – concept tokening relations, but argues that it is purely accidental for reference. In contrast, I argue that the actual mechanisms that (...) sustain the reference determining concept tokening relations are necessary for reference. Thus, to possess a concept it is necessary to possess some specific sustaining mechanism. (shrink)

How can one distinguish the concept of second modernity from the concept of postmodernity? Postmodernists are interested in deconstruction without reconstruction, second modernity is about deconstruction and reconstruction. Social sciences need to construct new concepts to understand the world dynamics at the beginning of the 21st century.Modernity has not vanished, we are not post it. Radical social change has always been part of modernity. What is new is that modernity has begun to modernize its own foundations. This is what (...) it means to say modernity has become reflexive. It has become directed at itself. This causes huge new problems both in reality and in theory. There has been a pluralization of the boundaries within and between societies, between society and nature, between Us and Other, between life and death. This pluralization also changes the inherent nature of boundaries. They become not so much boundaries as a variety of attempts to draw of boundaries. Border conflicts become transformed into conflicts over the drawing of boundaries. Where postmodernism simply celebrates this multiplication of boundaries, the theory of second modernity starts with the problem this new reality poses for individual and collective decisions, and with the problem that the continued existence of such decisions poses for theory. Institutions that are capable of such conscious boundary drawing are enabled in a way that those of the first modernity were not. But this process also generates qualitatively new kinds of trouble and crises. To investigate those troubles is to unveil the emergence of the second modernity. (shrink)

In this paper, I argue that descriptive information associated with concepts plays a relevant role in the performance of different cognitive tasks, as suggested by Descriptivist Theories of Concepts (DTC). However, I argue that it does not follow that such information determines the extension of concepts, as also suggested by DTC. In support of these claims, I present an analysis of empirical evidence offered by cases of semantic dementia. According to this interpretation of such evidence, the information (...) associated with concepts is part of the cognitive content of concepts. It is involved in different cognitive tasks, but such evidence does not support the thesis that it is possible to determine the intentional content, i.e., the extension of a concept from the cognitive content, since to do so would face the objection of ignorance.

A theory of conceptual development must specify the innate representational primitives, must characterize the ways in which the initial state differs from the adult state, and must characterize the processes through which one is transformed into the other. The Origin of Concepts (henceforth TOOC) defends three theses. With respect to the initial state, the innate stock of primitives is not limited to sensory, perceptual, or sensorimotor representations; rather, there are also innate conceptual representations. With respect to developmental change, (...) conceptual development consists of episodes of qualitative change, resulting in systems of representation that are more powerful than, and sometimes incommensurable with, those from which they are built. With respect to a learning mechanism that achieves conceptual discontinuity, I offer Quinian bootstrapping. TOOC concludes with a discussion of how an understanding of conceptual development constrains a theory of concepts. (shrink)

This is a contribution to the symposium on Herman Cappelen’s book Fixing Language. Cappelen proposes a metasemantic framework—the “Austerity Framework”—within which to understand the general phenomenon of conceptual engineering. The proposed framework is austere in the sense that it makes no reference to concepts. Conceptual engineering is then given a “worldly” construal according to which conceptual engineering is a process that operates on the world. I argue, contra Cappelen, that an adequate theory of conceptual engineering must make reference (...) to concepts. This is because concepts are required to account for topic continuity, a phenomenon which lies at the heart of projects in conceptual engineering. I argue that Cappelen’s own account of topic continuity is inadequate as a result of the austerity of his metasemantic framework, and that his worldly construal of conceptual engineering is untenable.

The article explains the notion of univocity in line with the mature Scotistic doctrine, which plays so crucial a role in the Scotistic rejection of analogy as a middle ground between univocity and pure equivocity. Since univocity of a concept is found to consist in its perfect unity, and the perfect unity of a concept is achieved by means of perfect abstraction, the notion of this so-called abstraction by precision is made clear and contrasted with the so-called abstraction by confusion, (...) by means of which analogical concepts are supposed to be formed by the Thomists.

This article outlines a new theory of humor. The concept of humor is developed in the sense of five dialectical levels, respectively, sequential phenomenalities of humorous consciousness. These range from a level of most inferior humor up to a stage of most sublime humor. Systematically speaking, humor is viewed from an enhanced perspective of transcendental philosophy, namely as a medium of self-unfolding practical reason. It is considered as a complementary potency to the practical force of the latter’s regulative principle, (...) and it fulfils several important functions. The first section provides basic definitions of concepts like humor, sublimity, comicality, etc. Here, the five phenomenalities of humor are introduced. The second section explores and develops these contents more in detail. Some references to the German-speaking tradition in the philosophy of humor provide further input for discussion. The third section presents a thought experiment. Imaginary humorous reactions of Socrates to ridicule and hostility are analyzed in the sense of the present theory. (shrink)

We argue that thoughts are structures of concepts, and that concepts should be individuated by their origins, rather than in terms of their semantic or epistemic properties. Many features of cognition turn on the vehicles of content, thoughts, rather than on the nature of the contents they express. Originalism makes concepts available to explain, with no threat of circularity, puzzling cases concerning thought. In this paper, we mention Hesperus/Phosphorus puzzles, the Evans-Perry example of the ship seen through (...) different windows, and Mates cases, and we believe that there are many additional applications.

Since the BBS article in which Premack and Woodruff (1978) asked “Does the chimpanzee have a theory of mind?,” it has been repeatedly claimed that there is observational and experimental evidence that apes have mental state concepts, such as “want” and “know.” Unlike research on the development of theory of mind in childhood, however, no substantial progress has been made through this work with nonhuman primates. A survey of empirical studies of imitation, self-recognition, social relationships, deception, role-taking, (...) and perspective-taking suggests that in every case where nonhuman primate behavior has been interpreted as a sign of theory of mind, it could instead have occurred by chance or as a product of nonmentalistic processes such as associative learning or inferences based on nonmental categories. Arguments to the effect that, in spite of this, the theory of mind hypothesis should be accepted because it is more parsimonious than alternatives or because it is supported by convergent evidence are not compelling. Such arguments are based on unsupportable assumptions about the role of parsimony in science and either ignore the requirement that convergent evidence proceed from independent assumptions, or fail to show that it supports the theory of mind hypothesis over nonmentalist alternatives. Progress in research on theory of mind requires experimental procedures that can distinguish the theory of mind hypothesis from nonmentalist alternatives. A procedure that may have this potential is proposed. It uses conditional discrimination training and transfer tests to determine whether chimpanzees have the concept “see.” Commentators are invited to identify flaws in the procedure and to suggest alternatives. Key Words: apes; associative learning; concepts; convergence; deception; evolution of intelligence; folk psychology; imitation; mental state attribution; monkeys; parsimony; perspective-taking; primates; role-taking; self-recognition; social cognition; social intelligence; theory of mind.

Much of the scholarship on Kant’s theory of concept formation has focused on the question of whether his theory suffers from circularity, i. e., whether it presupposes the very concepts whose origin it should explain. In this article, I defend Kant against a well-known objection raised by Hannah Ginsborg. Ginsborg, I argue, overlooks the relatively narrow aim of Kant’s theory of concept formation. Kant explicitly frames it as an account of a concept’s inherent generality, or form. (...) However, Ginsborg’s objection is not about a concept’s form; it concerns the concept’s content. Moreover, Kant addresses the issue that she raises in his theory of definitions, which explains how a concept’s content can be revised and perfected. Kant considered all empirical concepts to be incomplete and imprecise. For this reason, he denied that they can be properly defined. Kant also did not regard the content of empirical concepts as fixed or permanent. Indeed, he expected that we would continually expand and revise their content on the basis of experience. I argue that these facts, along with the narrow scope of Kant’s theory of concept formation, effectively defuse Ginsborg’s objection. (shrink)

'Concept' is a central notion in modern philosophy. This book deals with the philosopher Aristotle to compare modern theories of 'concepts' as he is said to be the predecessor both of classical theory and of modal theories of 'concepts' in the modern debate. Both pathêma and logos are central to his theory of language, thought, and concepts.

The problem of the reduction of chemistry to physics has been traditionally addressed in terms of classical structural chemistry and standard quantum mechanics. In this work, we will study the problem from the perspective of the Quantum Theory of Atoms in Molecules, proposed by Richard Bader in the nineties. The purpose of this article is to unveil the role of QTAIM in the inter-theoretical relations between chemistry and physics. We argue that, although the QTAIM solves two relevant obstacles to (...) reduction by providing a rigorous definition of chemical bond and of atoms in a molecule, it appeals to concepts that are unacceptable in the quantum–mechanical context. Therefore, the QTAIM fails to provide the desired reduction. On the other hand, we will show that the QTAIM is more similar to Bohmian mechanics and that the basic elements of both theories are closely related. (shrink)

Moral-theoretical categories have almost disappeared from the theoretical vocabulary of sociology. Neither perceptions of legitimacy nor perceptions of injustice, neither moral argument nor normative consensus now play a significant role in explaining the social order. Instead the object of sociological inquiry is understood either according to the pattern of anonymous self-organization processes or as the result of cooperation among strategically-oriented actors; accordingly, the disciplinary role models are biology or economics, whose conceptual models appear suited to explain such a complex process (...) as the reproduction of societies. One may easily get the impression that current sociology wishes to finally bid farewell to the generation of its founding fathers; since from Weber and Durkheim to Talcott Parsons, it was a settled matter that an adequate basic conception of the social world could only be derived using the concepts, models, or hypotheses of moral theory – practical philosophy was, so to speak, the foundation and guiding discipline for classical sociology. After the “Theory of Communicative Action”– the last grand sketch of a complete social theory based on the sources of practical philosophy – all this seems to have been forgotten. In any event, it could until recently appear that with Habermas’ book the tradition of a normatively oriented sociology has come to an end. It is mostly due to the efforts of a small group of researchers in France – which assembled around Luc Boltanski and Laurent Thévenot – that there continues to be a strand within social theory that employs sources of moral philosophy. Having emerged from an internal critique of Pierre Bourdieu's sociology, the works of this highly productive circle, probing ever new directions, seek to explain the integration of our societies through the interplay of different moral convictions.1 The foundational text of this sociological school is the study On Justification, originally published in 1991.2 This book, which has meanwhile also been published in German,3 deserves careful consideration not least because it represents the most interesting attempt of the more recent past to give sociology a basis in moral philosophy.

It is argued that ideas and theories often evolve into preconceptions of our perceptions. Such evolution is implicit in Heidegger's notion of truths of alethia. The description of this process holds implications for the traditional givenness of humans for themselves in terms of the changabllity of absolute presuppositions. Among the implications are 1. the insufficiency of the historical mode for explaining changes in human self-perception; 2. the inadequacy of radical subjectivism and environmentalism; 3. a radical contingency and complexity to the (...) course of human conceptualization; and 4. the awareness that human efforts can influence alterations in preconceptions. The influence of modern brain theory is subject to these conditions. (shrink)

Mitchell's formulation of the chemiosmotic theory of oxidative phosphorylation in 1961 lacked any experimental support for its three central postulates. The path by which Mitchell reached this theory is explored. A major factor was the role of Mitchell's philosophical system conceived in his student days at Cambridge. This system appears to have become a tacit influence on his work in the sense that Polanyi understood all knowledge to be generated by an interaction between tacit and explicit knowing. Early (...) in his life Mitchell had evolved a simple philosophy based on fluctoids, fluctids and statids which was developed in a thesis submitted for the Ph.D. at the University of Cambridge, England. This aspect of his work was rejected by the examiners and became a tacit element in his intellectual development. It is argued from his various publications that this philosophy can be traced as an underlying theme behind much of Mitchell's theoretical writing in the 50's leading, through his notion of vectorial metabolism, to the formulation and amplification of the chemiosmotic theory in the sixties. This philosophy formed the basis for Mitchell of his understanding of biological systems and gave him his unique approach to cell biology. (shrink)

Christian Pfeiffer explores an important, but neglected topic in Aristotle's theoretical philosophy: the theory of bodies. A body is a three-dimensionally extended and continuous magnitude bounded by surfaces. This notion is distinct from the notion of a perceptible or physical substance. Substances have bodies, that is to say, they are extended, their parts are continuous with each other and they have boundaries, which demarcate them from their surroundings. Pfeiffer argues that body, thus understood, has a pivotal role in Aristotle's (...) natural philosophy. A theory of body is a presupposed in, e.g., Aristotle's account of the infinite, place, or action and passion, because their being bodies explains why things have a location or how they can act upon each other. The notion of body can be ranked among the central concepts for natural science which are discussed in Physics III-IV. (shrink)

Habermas's theory of social evolution has been subjected to critique by environmentally motivated sociologists. They argue that his decision to recast social theory in terms of an extended, if selective analogy with biology leads him into a set of practical positions that are irreconcilable with Green politics and inconsistent with the goals of traditional critical theory. This article argues that these criticisms are based on an inaccurate assessment of the role of evolutionary concepts in Habermas's thought. (...) By drawing out the similarities between Habermas and Kant on the question of the relationship between history and natural history, it is possible to see that Habermas's use of evolutionary metaphors plays a regulative rather than a constitutive role in his thinking on society. This strategy does not save Habermas's position, but shows instead that it may be vulnerable to an immanent critique that pulls out the real underlying antagonisms in his system. (shrink)

A formal theory of truth, alternative to tarski's 'orthodox' theory, based on truth-value gaps, is presented. the theory is proposed as a fairly plausible model for natural language and as one which allows rigorous definitions to be given for various intuitive concepts, such as those of 'grounded' and 'paradoxical' sentences.

The Universe is One places the ancient synthesis of Stoicism, Platonism, Judaism, and Christianity in active dialogue with modern process science in order to conjoin science, philosophy, and theology into the human quest for meaning. Paul A. Olivier proposes a comprehensive theory of knowledge, which he expands into a theory of life, correlating modern process science and the western-Judeo-Christian heritage into a grand theory of the Universe. He brings together the ideas of influential thinkers from the world (...) of science with those from the world of New Testament studies. Olivier clearly explains concepts from diverse fields to construct a satisfying theory of knowledge and life. He accomplishes this through an examination of the dominance of polarity in all aspects of the universe, such as chaos and order, predictability and unpredictability. Through this complex blend of opposites Olivier develops his theory as an interaction of Word and Spirit that provides the Universe with everything necessary to account for its creation and ongoing evolution. The Universe continually creates and sustains itself out of its own internal necessity coupled paradoxically with the fluidity of its own inherent unpredictability. (shrink)

The character of computational modelling of cognition depends on an underlying theory of representation. Classical cognitive science has exploited the syntax/semantics theory of representation that derives from logic. But this has had the consequence that the kind of psychological explanation supported by classical cognitive science is

_conceptualist_:

psychological phenomena are modelled in terms of relations that hold between concepts, and between the sensors/effectors and concepts. This kind of explanation is inappropriate for the Proper Treatment (...) of Connectionism (Smolensky 1988). (shrink)

In this article, the authors try to answer the following questions: How can an object/instance seen for the first time extend a category or update a concept? How is it possible to determine the reference of a concept that represents a behaviour? In the first case, the authors discuss the learning of inferential linguistic competence used to update a concept through an approach based on prototype theory. In the second case, the authors discuss the learning of referential linguistic competence (...) used to determine the reference of a concept (i.e., determination of an actual behaviour) through an approach based on embodied cognition. The authors show how combining prototype-based and embodied categorization in Wittgenstein’s rule-following praxis (the individual and community dimension), linguistic learning of a concept (inferential competence), and determination of its reference (referential competence) can be traced back to the same model.

Our computational metaphysics group describes its use of automated reasoning tools to study Leibniz’s theory of concepts. We start with a reconstruction of Leibniz’s theory within the theory of abstract objects (henceforth ‘object theory’). Leibniz’s theory of concepts, under this reconstruction, has a non-modal algebra of concepts, a concept-containment theory of truth, and a modal metaphysics of complete individual concepts. We show how the object-theoretic reconstruction of these components of Leibniz’s (...) theory can be represented for investigation by means of automated theorem provers and finite model builders. The fundamental theorem of Leibniz’s theory is derived using these tools. (shrink)

This paper contains a critical discussion of Paul Horwich's use theory of meaning. Horwich attempts to dissolve the problem of representation through a combination of his theory of meaning and a deflationism about truth. I argue that the dissolution works only if deflationism makes strong and dubious claims about semantic concepts. Horwich offers a specific version of the use theory of meaning. I argue that this version rests on an unacceptable identification: an identification of principles that (...) are fundamental to an explanation of the acceptance of sentences with principles that are fundamental to meaning.

The relativist position on knowledge is summarized by Protagoras’ phrase “Man is the measure of all things”. Protagoras’ detractors countered that there was no reason for his pupils to employ him since, by his own admission, his lessons lacked privilege. This the educationist’s relativist paradox. The Enlightenment tradition of Descartes, Locke and Kant solved this paradox by distinguishing given objective knowledge from constructed subjective knowledge, but this position has itself been discredited by the work of Sellars, Quine and many other (...) thinkers. Because the Enlightenment solution to the educationist’s relativist paradox is no longer satisfactory, an alternative solution to this paradox is proposed. This alternative re-examines both the basis of empiricism and the role and origins of language, and introduces the concepts of triggered hallucinations, cognitive evolutionary pressure, and cognitive empathetic resonance. Cognitive empathetic resonance provides a mechanism that can explain how our thoughts and actions are made possible by language; it is language that acts as a creative and generative force and helps us to live in the world we do. This approach inverts the empiricist claim that ideas start off grounded in an external reality and develop into more sophisticated concepts. The view of ideas presented here is that ideas are free-floating and, if they are grounded at all, are grounded as an active post-hoc process. The conclusion is that although facts do exist and are privileged, this is not because they are ‘given’ but because they are the ante required to join a space of discourse. (shrink)
