This article explores the complementary strengths and weaknesses of grounded and abstract representations in the domain of early algebra. Abstract representations, such as algebraic symbols, are concise and easy to manipulate but are distanced from any physical referents. Grounded representations, such as verbal descriptions of situations, are more concrete and familiar, and they are more similar to physical objects and everyday experience. The complementary computational characteristics of grounded and abstract representations lead to trade‐offs in problem‐solving performance. In prior research with (...) high school students solving relatively simple problems, Koedinger and Nathan (2004) demonstrated performance benefits of grounded representations over abstract representations—students were better at solving simple story problems than the analogous equations. This article extends this prior work to examine both simple and more complex problems in two samples of college students. On complex problems with two references to the unknown, a “symbolic advantage” emerged, such that students were better at solving equations than analogous story problems. Furthermore, the previously observed “verbal advantage” on simple problems was replicated. We thus provide empirical support for a trade‐off between grounded, verbal representations, which show advantages on simpler problems, and abstract, symbolic representations, which show advantages on more complex problems.

Ethical reasoning and decision-making may be thought of as 'professional skills', and in this sense are as relevant to efficient clinical practice as the biomedical and clinical sciences are to the diagnosis of a patient's problem. Despite this, however, undergraduate medical programmes in ethics tend to focus on the teaching of bioethical theories, concepts and/or prominent ethical issues such as IVF and euthanasia, rather than the use of such ethics knowledge (theories, principles, concepts, rules) to clinical practice. Not surprisingly, many (...) students and clinicians experience considerable difficulty in using what they know about ethics to help them make competent ethical decisions in their day-to-day clinical practice. This paper describes the development of a seminar programme for teaching senior medical students a more systematic approach to ethical reasoning and analysis and clinical decision-making. (shrink)

Psychopaths continue to be demonised by the media and estimates suggest that a disturbing percentage of the population has psychopathic tendencies. This timely and controversial new book summarises what we already know about psychopathy and antisocial behavior and puts forward a new case for its cause - with far-reaching implications. Presents the scientific facts of psychopathy and antisocial behavior. Addresses key questions, such as: What is psychopathy? Are there psychopaths amongst us? What is wrong with psychopaths? Is psychopathy due to (...) nature or nurture? And can we treat psychopaths? Reveals the authors' ground-breaking research into whether an underlying abnormality in brain development leaves psychopaths with an inability to feel emotion or fear. The resulting theory could lead to early diagnosis and revolutionize the way society, the media and the state both views and contends with the psychopaths in our midst. (shrink)

A quick look at what is happening in the corporate world makes it clear that the stakeholder idea is alive, well, and flourishing; and the question now is not “if ” but “how” stakeholder theory will meet the challenges of its success. Does stakeholder theory’s “arrival” mean continued dynamism, refinement, and relevance, or stasis? How will superior stakeholder theory continue to develop? In light of these and related questions, the authors of these essays conducted an ongoing dialogue on the current (...) state and future of stakeholder thinking. Beginning with a review of research and theory that has developed since the major stakeholder theorizing efforts of the 1990s, the authors individually offer their perspectives on the key issues relevant today to stakeholder thinking, and to suggest possible approaches that might lead toward and enable the continuing development of superior stakeholder theory.

This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)

To contribute to the continuing challenge of explaining how managers identify stakeholders and assess their salience, in this article, we chronicle the history, assess the impact, and evaluate the possibilities opened by Mitchell, Agle, and Wood (MAW-1997). We do so through two types of qualitative analysis, and also through utilizing a quantitative network analysis tool. The first qualitative analysis categorizes the major contributions of the most influential papers succeeding MAW-1997; the second identifies and compares the relevant issues with MAW-1997 (...) at the time of initial publication and today. We apply main path analysis, a quantitative tool, to map how this scholarly domain has evolved. These three analyses robustly depict the impact of MAW-1997 and the ensuing scholarly conversation, and they enable us to illustrate the current state and trajectory of stakeholder identification and salience scholarship. We close by discussing pressing topics related to the broader body of stakeholder theory literature. (shrink)

EDITED BY SLAVENKO ŠLJUKIĆBOOK SYMPOSIUM ON KENNETH R. WESTPHAL’S HOW HUME AND KANT RECONSTRUCT NATURAL LAW.

Kant famously declares that “although all our cognition commences with experience, … it does not on that account all arise from experience”. This marks Kant’s disagreement with empiricism, and his contention that human knowledge and experience require both sensation and the use of certain a priori concepts, the Categories. However, this is only the surface of Kant’s much deeper, though neglected view about the nature of reason and judgment. Kant holds that even our a priori concepts are acquired, not from (...) sensation, but “originally,” because our mind has a fundamental capacity to judge that, upon sensory stimulation, generates the Categories through its basic logical functions of judgment. This “epigenesis” of reason and our fundamental capacity to judge that drives it is the topic of Longuenesse’s fascinating book, and the source of her title. (shrink)

Kenneth R. Westphal presents an original interpretation of Hume's and Kant's moral philosophies, the differences between which are prominent in current philosophical accounts. Westphal argues that focussing on these differences, however, occludes a decisive, shared achievement: a distinctive constructivist account of the basic principles of justice which justifies their strict objectivity without invoking moral realism nor moral anti- or irrealism. Westphal explores how Hume developed a kind of constructivism for basic property rights and for government, and how Kant greatly (...) refined Hume's construction of justice within his 'metaphysical principles of justice', whilst preserving the core model of Hume's innovative account. Westphal contends that Hume's and Kant's constructivism avoids the conventionalist and relativist tendencies latent if not explicit in contemporary forms of moral constructivism. (shrink)

This book is the first detailed study of Kant's method of 'transcendental reflection' and its use in the Critique of Pure Reason to identify our basic human cognitive capacities, and to justify Kant's transcendental proofs of the necessary a priori conditions for the possibility of self-conscious human experience. Kenneth Westphal, in a closely argued internal critique of Kant's analysis, shows that if we take Kant's project seriously in its own terms, the result is not transcendental idealism but realism regarding (...) physical objects. Westphal attends to neglected topics - Kant's analyses of the transcendental affinity of the sensory manifold, the 'lifelessness of matter', fallibilism, the semantics of cognitive reference, four externalist aspects of Kant's views, and the importance of Kant's Metaphysical Foundations for the Critique of Pure Reason - that illuminate Kant's enterprise in new and valuable ways. His book will appeal to all who are interested in Kant's theoretical philosophy. (shrink)

Legally blind participants were able to identify a visual stimulus attribute in the absence of consciously identifying its presence. Specifically, participants—with their corrective lenses removed—correctly guessed the hour-hand position above chance on a clockface shown on a computer screen. This occurred both when presented in a 1-clockface display , as well as when shown a display containing 4 clockfaces , in which only 1 face contained a hand. Even more striking, hand identification accuracy in the 4-clockface condition was comparable whether (...) the clockface containing the hand was or was not correctly identified. That legally blind individuals are capable of identifying stimulus attributes without conscious awareness provides an additional vehicle for exploring implicit perception. Consistent with previous research, the visualsystem can apparently cope with degraded visual input through information available through a secondary pathway via the superior colliculi. (shrink)

The scope of this study is both ambitious and modest. One of its ambitions is to reintegrate Hegel's theory of knowledge into main stream epist~ology. Hegel's views were formed in consideration of Classical Skepticism and Modern epistemology, and he frequently presupposes great familiarity with other views and the difficulties they face. Setting Hegel's discussion in the context of both traditional and contemporary epistemology is therefore necessary for correctly interpreting his issues, arguments, and views. Accordingly, this is an issues-oriented study. I (...) analyze Hegel's problematic and method by placing them in the context of Sextus Empiricus, Descartes, Kant, Carnap, and William Alston. I discuss Carnap, rather than a Modern empiricist such as Locke or Hume, for several reasons. One is that Hegel himself refutes a fundamental presupposition of Modern empiricism, the doctrine of "knowledge by acquaintance," in the first chapter of the Phenomenology, a chapter that cannot be reconstructed within the bounds of this study.

This book assesses and defends Kant's Critical epistemology, and the rich yet neglected resources it provides for understanding and resolving fundamental issues regarding human experience, perceptual judgment, empirical knowledge and cognitive sciences. Kenneth Westphal first examines Kant's methods and strategies for examining human sensory-perceptual experience, and then examines Kant's central, proper, and subtle attention to judgment, and so to the humanly possible valid use of concepts and principles to judge particulars we confront. This provides a comprehensive account of Kant's (...) anti-Cartesianism, the integrity of his three principles of causal judgment, and Kant's account of disciminatory perceptual-motor behaviour, including both sensory reafference and perceptual affordances. Westphal then defends the significance of Kant's subtle and illuminating account of causal judgment for three main philosophical domains: history and philosophy of science, theory of action and human freedom, and philosophy of mind. Kant's Critical Epistemology will appeal to researchers and advanced students interested in Kant and the relations of his thought to contemporary philosophical debates and to the sciences of the mind.

Though concise and introductory, this book argues inter alia that Dretske’s information-theoretic epistemology must take into account that many of our information channels are socially constructed, not least through learning concepts and information. These social aspects of human knowledge are consistent with realism about the objects of our empirical knowledge. It further argues that, though important, Margaret Gilbert’s social ontology in principle can neither accommodate nor account for the most fundamental social dimensions of human cognition.

A 5,000-word conspectus of Hegel’s moral philosophy which considers the theoretical context of his moral philosophy (§1), his accounts of legal, personal, moral and social freedom (§2), the structure of Hegel’s analysis in his Philosophy of Justice (or »Rechtsphilosophie«) (§3), his account of role obligations as a central component of social freedom (§4), and his integrated account of individual autonomy and social reconciliation (§5).

There is widespread consensus that present patterns of consumption could lead to the permanent impossibility of maintaining those patterns and, perhaps, the existence of the human race. While many patterns of consumption qualify as ‘sustainable’ there is one in particular that deserves greater attention: virtual consumption. We argue that virtual consumption — the experience of authentic consumptive experiences replicated by alternative means — has the potential to reduce the deleterious consequences of real consumption by redirecting some consumptive behavior from shifting (...) material states to shifting information states.

In this book, Westphal offers an original interpretation of Hegel's moral philosophy. Building on his previous study of the role of natural law in Hume's and Kant's accounts of justice, Westphal argues that Hegel developed and justified a robust form of civic republicanism. Westphal identifies, for the first time, the proper genre to which Hegel's Philosophical Outlines of Justice belongs and to which it so prodigiously contributes, which he calls Natural Law Constructivism, an approach developed by Hume, Rousseau, Kant, and (...) Hegel. He brings to bear Hegel's adoption and augmentation of Kant's Critique of rational judgment and justification in all non-formal domains to his moral philosophy in his Outlines. Westphal argues that Hegel's justification for the standards of political legitimacy successfully integrates Rousseau's Independence Requirement into the role of public reason within a constitutional republic. In these regards, Hegel's moral and political principles are progressive not only in principle, but also in practice. Hegel's Civic Republicanism will be of interest to scholars of moral philosophy, social and political philosophy, philosophy of law, Hegel, eighteenth- and nineteenth-century philosophy. (shrink)

This article examines how Quine and Sellars develop informatively contrasting responses to a fundamental tension in Carnap’s semantics ca. 1950. Quine’s philosophy could well be styled ‘Essays in Radical Empiricism’; his assay of radical empiricism is invaluable for what it reveals about the inherent limits of empiricism. Careful examination shows that Quine’s criticism of Carnap’s semantics in ‘Two Dogmas of Empiricism’ fails, that at its core Quine’s semantics is for two key reasons incoherent and that his hallmark Thesis of Extensionalism (...) is untenable. The tension in Carnap’s semantics together with Quine’s exposure of the severe limits of radical empiricism illuminate central features of Sellars’s philosophy: the fully general form of the myth of givenness, together with Sellars’s alternative Kantian characterisation of understanding; the full significance of Carnap’s distinction between conceptual analysis and conceptual explication, and its important methodological implications; the specifically pragmatic character of Sellars’s realism; and Sellars’s methodological reasons for holding that philosophy must be systematic and that systematic philosophy must be deeply historically and textually informed. This paper thus re-examines this recent episode of philosophical history for its philosophical benefits and systematic insights. (shrink)

Ken Hammond has been an influential figure in the study of decision making; with this book, he aims to show why mistaken judgments happen, how to make better decisions, and how to understand the thought modes operating in the political process.

We present a new model of skilled performance in geometry proof problem solving called the Diagram Configuration model (DC). While previous models plan proofs in a step‐by‐step fashion, we observed that experts plan at a more abstract level: They focus on the key steps and skip the less important ones. DC models this abstract planning behavior by parsing geometry problem diagrams into perceptual chunks, called diagram configurations, which cue relevant schematic knowledge. We provide verbal protocol evidence that DC's schemas correspond (...) with the step‐skipping inferences experts make in their initial planning. We compare DC with other models of geometry expertise and then, in the final section, we discuss more general implications of our research. DC's reasoning has important similarities with Larkin's (1988) display‐based reasoning approach and Johnson‐Laird's (1983) mental model approach. DC's perceptually based schemas are a step towards a unified explanation of (1) experts' superior problem‐solving effectiveness, (2) experts' superior problem‐state memory, and (3) experts' ability, in certain domains, to solve relatively simple problems by pure forward inferencing. We also argue that the particular and efficient knowledge organization of DC challenges current theories of skill acquisition as it presents an end‐state of learning that is difficult to explain within such theories. Finally, we discuss the implications of DC for geometry instruction. (shrink)

This collection of original essays aims to reinvigorate the debate surrounding philosophical realism in relation to philosophy of science, pragmatism, epistemology, and theory of perception. Questions concerning realism are as current and as ancient as philosophy itself; this volume explores relations between different positions designated as ‘realism’ by examining specific cases in point, drawn from a broad range of systematic problems and historical views, from ancient Greek philosophy through the present. The first section examines the context of the project; contributions (...) systematically engage the historical background of philosophical realism, re-examining key works of Aristotle, Descartes, Quine, and others. The following two sections epitomize the central tension within current debates: scientific realism and pragmatism. These contributions address contemporary questions of scientific realism and the reality of the objects of science, and consider whether, how or the extent to which realism and pragmatism are compatible. With an editorial introduction by Kenneth R. Westphal, these fourteen original essays provide wide-ranging, salient insights into the status of realism today. (shrink)

This article reconstructs Hegel’s chapter “Sense Certainty” (Phenomenology of Spirit, chap. 1) in detail in its historical and philosophical context. Hegel’s chapter develops a sound internal critique of naive realism that shows that sensation is necessary but not sufficient for knowledge of sensed particulars. Cognitive reference to particulars also requires using a priori conceptions of space, spaces, time, times, self, and individuation. Several standard objections to and misinterpretations of Hegel’s chapter are rebutted. Hegel’s protosemantics is shown to accord in important (...) regards with Gareth Evans’ view in “Identity and Predication.”. (shrink)

The dominant conception of educational equality in the United States is meritocratic: an individual's chances of educational achievements should track only talent and effort, not social class or other morally irrelevant factors. The meritocratic conception must presuppose that natural talent and effort can be isolated from social class — and environmental factors in general — if it is to provide guidance in the world of educational policy and practice. In this article Kenneth R. Howe challenges that presupposition and related (...) elements of the meritocratic conception having to do with the role of competition and education as a positional good. Howe argues that, in use, the meritocratic conception unavoidably distributes education based on developed talent and motivation that cannot be isolated from the effects of social class, thus masking the real basis of the distribution and contributing to the perpetuation of illicit group privilege. Howe then entertains and rejects several rejoinders to his critique, including that the meritocratic conception might eliminate the presupposition of isolatable natural talent. Finally, Howe sketches an alternative conception of educational equality based on Elizabeth Anderson's adaptation of Rawls's “democratic equality.”. (shrink)

According to Kant, justifying the application of mathematics to objects in natural science requires metaphysically constructing the concept of matter. Kant develops these constructions in the Metaphysical Foundations of Natural Science (MAdN). Kant’s specific aim is to develop a dynamic theory of matter to replace corpuscular theory. In his Preface Kant claims completely to exhaust the metaphysical doctrine of body, but in the General Remark to MAdN ch. 2, “Dynamics,” Kant admits that once matter is reconceived as basic forces, it (...) is no longer possible to construct the concept of matter. I argue that Kant’s admission is only the tip of the problem, and that none of Kant’s commentators has fully grasped the problems infecting the MAdN that underlie Kant’s admission. I show that Kant’s proof that matter consists of forces is fallacious. I then re-analyze the circularity in Kant’s definition of density, criticizing both Adickes’ formulations and his later dissolution of it. I also show that a third circularity infects the relations between Kant’s treatment of “Dynamics” and “Mechanics” (MAdN ch. 3). These three fundamental problems demonstrate the untenability of Kant’s metaphysical method, and they require the radical revision of the relation between mathematics and metaphysics Kant undertakes in his opus postumum. I show that some of Kant’s most surprising and critical later claims about the Critical philosophy are correct, and that they require the sorts of remedies Kant contemplates in the opus postumum. (I defend the essentially correct analyses offered by Burkhard Tuschling and Eckart Forster against criticisms by Michael Friedman.). (shrink)

I argue that Hegel is aware of a crucial problem in Kant’s transcendental account of the conditions of human knowledge. Unless the matter of sensation is sufficiently ordered (and sufficiently varied) we could not make any cognitive judgments. In that case we could not distinguish ourselves from objects we know, and so could not be self-conscious. This is a necessary, formal and transcendental condition of possible human experience. However, it is also (as Kant acknowledged) a material – not a conceptual (...) or an intutive – condition. Consequently, Kant’s idealism cannot account for it. This provides one key to Hegel’s internal critique of Kant’s idealism. (shrink)

Despite the accumulation of substantial cognitive science research relevant to education, there remains confusion and controversy in the application of research to educational practice. In support of a more systematic approach, we describe the Knowledge-Learning-Instruction (KLI) framework. KLI promotes the emergence of instructional principles of high potential for generality, while explicitly identifying constraints of and opportunities for detailed analysis of the knowledge students may acquire in courses. Drawing on research across domains of science, math, and language learning, we illustrate the (...) analyses of knowledge, learning, and instructional events that the KLI framework affords. We present a set of three coordinated taxonomies of knowledge, learning, and instruction. For example, we identify three broad classes of learning events (LEs): (a) memory and fluency processes, (b) induction and refinement processes, and (c) understanding and sense-making processes, and we show how these can lead to different knowledge changes and constraints on optimal instructional choices.

This Open Access book provides both a broad perspective and a focused examination of cow care as a subject of widespread ethical concern in India, and increasingly in other parts of the world. In the face of what has persisted as a highly charged political issue over cow protection in India, intellectual space must be made to bring the wealth of Indian traditional ethical discourse to bear on the realities of current human-animal relationships, particularly those of humans with cows. Dharma, (...) yoga, and bhakti paradigms serve as starting points for bringing Hindu--particularly Vaishnava Hindu--animal ethics into conversation with contemporary Western animal ethics. The author argues that a culture of bhakti--the inclusive, empathetic practice of spirituality centered in Krishna as the beloved cowherd of Vraja--can complement recently developed ethics-of-care thinking to create a solid basis for sustaining all kinds of cow care communities.

Hegel’s Philosophy of Right responds to two dichotomies. One is between the freedom of rational thought in its practical application and the givenness of natural impulses and desires. Against Kant Hegel argues that pure reason alone cannot determine the content of any maxim or principle of action. Thus Hegel must find a way in which the content of natural needs and impulses – the only source of content for maxims of action – can be transfigured into contents of rationally self-given (...) principles and maxims. Hegel also responds to the dichotomy between the individual agent and the social whole within which agents act. Hegel argues that this dichotomy is specious because human beings are fundamentally social practitioners and because neither social practices nor individual agents have priority over the other. There are no social practices without social practitioners and there are no social practitioners without social practices. Hegel’s response to this second dichotomy allows him to respond to the first one as well. The elaboration and specialization of natural needs and desires through exchange relations and the social division of labor transfigures the contents of those needs and desires into collectively self-given ends. The social practices producing this transfiguration and meeting these ends form the contents of implicit principles of right. These implicit principles are collectively self-given because they result from the social practices collectively developed to meet these needs. Only acts that are executed and accepted by an agent are free acts. This strong condition requires that an agent’s intentions correspond to the actual nature and consequences of his or her act. Since the aims, the principles, and the means of action are fundamentally social, these strong constraints entail that free action is possible only within a community which makes known its structure and the role of its members within it and their contribution to it, so that its members can act on the basis of that knowledge. Hegel’s theory of the state is a theory of a communal structure that makes such explicit, free action possible. In briefest compass, Hegel holds that laws are legitimate only insofar as they codify those practices that have been developed in order to achieve human freedom, and laws are obligatory only insofar as they are necessary for achieving human freedom. Hegel’s government is designed to codify and promulgate such laws. Hegel’s legislature is designed to make known to the citizens at large, through their corporate representatives, that laws have such a basis and how individual roles and actions fit within the community as a whole.

The First World War was supposed to end all wars, though soon followed WWII. Since 1945 wars continued to abound; now we confront a real prospect of a third world war. Many armed struggles and wars arise in attempts to end repressive government; still more are fomented by repressive governments, few of which acknowledge their repressive character. It is historically and culturally naive to suppose that peace is normal, and war an aberration; war, preparations for war and threats of war (...) belong to ‘normal’ human life. Our tolerance, acceptance or fostering of such repeated injustices and atrocities indicate pervasive failures to understand fundamentals of justice, and what we owe morally to ourselves and to all others, together with our responsibilities to preserve the biosphere, not merely our own store(s) of reserves. As matters both of justice and prudence we must re-orient ourselves, individually and collectively, to promote justice, peace and ecological responsibilities by identifying and instituting just forms of social cooperation, domestically and internationally. All of these are our problems, whether we recognize them or continue our pervasive negligence. We urgently require cogent understanding of the social dimensions of human judgment, rational assessment, right action, and public reason. This requires understanding (inter alia) how Kant’s explication of rational judgment and justification is fundamentally social, how these features of rational judgment and justification are constitutive of Kant’s account of individual autonomy, and how they are central to Kant’s account of proper public use of reason. Reasoning publically remains precarious, not because – as often alleged – the ‘Enlightenment project’ has failed. It has not failed, it has been thwarted, and in our public responsibilities we have too often failed it. (shrink)
