We apply the “wisdom of the crowd” idea to human category learning, using a simple approach that combines people's categorization decisions by taking the majority decision. We first show that the aggregated crowd category learning behavior found by this method performs well, learning categories more quickly than most or all individuals for 28 previously collected datasets. We then extend the approach so that it does not require people to categorize every stimulus. We do this using a model‐based (...) method that predicts the categorization behavior people would produce for new stimuli, based on their behavior with observed stimuli, and uses the majority of these predicted decisions. We demonstrate and evaluate the model‐based approach in two case studies. In the first, we use the general recognition theory decision‐bound model of categorization (Ashby & Townsend, ) to infer each person's decision boundary for two categories of perceptual stimuli, and we use these inferences to make aggregated predictions about new stimuli. In the second, we use the generalized context model exemplar model of categorization (Nosofsky, ) to infer each person's selective attention for face stimuli, and we use these inferences to make aggregated predictions about withheld stimuli. In both case studies, we show that our method successfully predicts the category of unobserved stimuli, and we emphasize that the aggregated crowd decisions arise from psychologically interpretable processes and parameters. We conclude by discussing extensions and potential real‐world applications of the approach. (shrink)

This thesis aims to propose and defend a new way of analysing and understanding the origin of genetics (from Mendel to Bateson). Traditionally philosophers used to analyse the history of genetics in terms of theories. However, I will argue that this theory-based approach is highly problematic. In Chapter 1, I shall critically review the theory-driven approach to analysisng the history of genetics and diagnose its problems. In Chapter 2, inspired by Kuhn’s concept “exemplar”, I shall make (...) a new interpretation of exemplar and introduce an exemplar-based approach. Before introducing my exemplar-based analysis, I find it necessary to scrutinise the origin of genetics from Mendel to Bateson. In Chapter 3, I shall reinterpret Mendel’s work on Pisum by re-examining Mendel’s paper (1865) and its historical research context. In Chapter 4, by carefully examining the conceptual changes, I argue that the rediscovery event in 1900 should be better characterised as attempts of incorporating Mendel’s work with the work of “rediscoverers” (i.e. de Vries, Correns, Tschermak, and Bateson) rather than a mere reintroduction to Mendel’s work. In Chapter 5, I shall use the exemplar-based approach to analysing and interpreting the origin of genetics from Mendel to Bateson. In Chapter 6, I shall defend my exemplar-based characterisation of the origin of genetics by dismissing the potential responses from the theory-driven one, critically examining a potential mechanism-based analysis, and making the further notes on the implication of taking the exemplar-based approach to investigate scientific practice.

Alexander Bird indicates that the significance of Thomas Kuhn in the history of philosophy of science is somehow paradoxical. On the one hand, Kuhn was one of the most influential and important philosophers of science in the second half of the twentieth century. On the other hand, nowadays there is little distinctively Kuhn’s legacy in the sense that most of Kuhn’s work has no longer any philosophical significance. Bird argues that the explanation of the paradox of Kuhn’s legacy is that (...) Kuhn took a direction opposite to that of the mainstream of the philosophy of science in his later academic career. This paper aims to provide a new way to understand and develop Kuhn’s legacy by revisiting the development of Kuhn’s philosophy of science in 1970s and proposing a new account of exemplar. Firstly, I propose my diagnosis of Kuhn’s “wrong turning” by identifying Kuhn’s two novel contributions: the introduction of paradigm and the proposal of the incommensurability thesis. Secondly, I argue that Kuhn made a conceptual/terminological turn from paradigm to theory, which undermined Kuhn’s novel contributions. Thirdly, I propose a new articulation of exemplar and propose an exemplar-based approach to analysing the history of science. Finally, I show how the exemplar-based approach can be applied to analyse the history of science by my case study of the early development of genetics. (shrink)

Responsible conduct of research training typically includes only a subset of the issues that ought to be included in science ethics and sometimes makes ethics appear to be a set of externally imposed rules rather than something intrinsic to scientific practice. A new approach to science ethics training based upon Pennock’s notion of the scientific virtues may help avoid such problems. This paper motivates and describes three implementations—theory-centered, exemplar-centered, and concept-centered—that we have developed in courses and workshops (...) to introduce students to this scientific virtue-based approach.

According to a seminal paper by Barsalou , frames are attribute-value-matrices for representing exemplars or concepts. Frames have been used as a tool for reconstructing scientific concepts as well as conceptual change within scientific revolutions . In the frame-based representations of scientific concepts developed so far the semantic content of concepts is determined by a set of attribute-specific values. This way of representing semantic content works best for prototype concepts and defined concepts of a conceptual taxonomy satisfying the no-overlap (...) principle. In addition to the semantic content of prototype concepts and defined concepts, frames can also contain empirical knowledge that is represented as constraints between the values of the frame. Beside prototype concepts and defined concepts, theoretical concepts that are multiply operationalized play an important role in science. However, so far no frame-based representation of theoretical concepts has been proposed. In this paper, it will be shown that theoretical concepts can be represented by frames and that frame-based representations of prototype concepts and defined concepts have another structure than frame-based representations of theoretical concepts. In order to explicate this difference, we will develop a frame-based method for representing all three kinds of concepts by means of mathematical graph-theory. One important consequence will be that the constraints of a frame representing a theoretical concept are entailed by the structure of the frame, as opposed to a frame representing defined or prototype concepts.

This methodological discussion invites critical reflection about the procedures used to analyze the contribution of qualitative and mixed methods research to nursing trials by mounting an argument that these should rest on multiple publications produced about a project, rather than a single article. We illustrate the value‐added of this approach with findings from a qualitative, cross‐case analysis of three critical case exemplars from nursing researchers that each used a qualitative approach with a mixed method phase. The holistic lens (...) afforded by a case‐based approach informs nursing inquiry by documenting that the critical case exemplars presented evidence of (a) a sustained commitment of resources and expertise for the qualitative methods that extended across more than one phase of the trial, (b) the impact of the qualitative methods on the trial or its aftermath, (c) deploying a theoretical or conceptual framework for a variety of purposes, and (d) integrating qualitative and quantitative data for purposes of extending explanatory power. Findings challenge the practice of linking purposes served by qualitative and mixed methods to a single trial phase. (shrink)

This paper confronts Zagzebski’s exemplarism with the intertwined debates over the conditions of exemplarity and the unity-disunity of the virtues, to show the advantages of a pluralistic exemplar-based approach to moral education (PEBAME). PEBAME is based on a prima facie disunitarist perspective in moral theory, which amounts to admitting both exemplarity in all respects and single-virtue exemplarity. First, we account for the advantages of PEBAME, and we show how two figures in recent Italian history (Giorgio Perlasca (...) and Gino Bartali) satisfy Blum’s definitions of ‘moral hero’ and ‘moral saint’ (1988). Then, we offer a comparative analysis of the effectiveness of heroes and saints with respect to character education, according to four criteria derived from PEBAME: admirability, virtuousness, transparency, and imitability. Finally, we conclude that both unitarist and disunitarist exemplars are fundamental to character education; this is because of the hero's superiority to the saint with respect to imitability, a fundamental feature of the exemplar for character education.

The question “What are cognitive processes?” can be understood variously as meaning “What is the nature of cognitive processes?”, “Can we distinguish epistemically cognitive processes from physical and biochemical processes on the one hand, and from mental or conscious processes on the other?”, and “Can we establish a fruitful notion of cognitive process?” The present aim is to deliver a positive answer to the last question by developing criteria for what would count as a paradigmatic exemplar of a cognitive (...) process, and then to offer the comparator mechanism as a convincing paradigmatic example. Thus, the paper argues, given the current state of science, we can indeed establish a fruitful scientific notion of a cognitive process. Nevertheless, it is left open whether the example-based characterization ends up as merely highlighting a fruitful convention within the early-twentyfirst century interdisciplinary investigation of intelligent behaviour in humans, animals, and robots, or whether the examples determine a natural kind or a property cluster.

This paper focuses on the idea of exemplarity outlined by the Italian critical theorist Alessandro Ferrara that forms part of his general case for the centrality of disclosure to emancipatory political reasoning. Ferrara argues that “at its best” political thought should have the capacity to animate the democratic imagination by disclosing new political worlds and hence new possibilities for thought and action. I argue that Ferrara’s notion of exemplarity provides important conceptual resources for a re-grounding of critical theory in the (...) type of experientially based disclosing critique that has, post Habermas, been marginalized. Ferrara’s work is significant in two respects. First, exemplary universalism provides a much-needed alternative to the assimilative paradigms of normative reasoning that dominate contemporary political theory. Exemplary normativity suggests a mode of reasoning from concrete particularity that is more inclusive than principle-based approaches of voices which, by virtue of their ma... (shrink)

A growing consensus in the philosophy and psychology of concepts is that while theories such as the prototype, exemplar, and theory theories successfully account for some instances of concept formation and application, none of them successfully accounts for all such instances. I argue against this ‘new consensus’ and show that the problem is, in fact, more severe: the explanatory force of each of these theories is limited even with respect to the phenomena often cited to support it, as each (...) fails to satisfy an important explanatory desideratum with respect to these phenomena. I argue that these explanatory shortcomings arise from a shared assumption on the part of these theories, namely, they take similarity judgements and application of causal knowledge to be discrete elements in a theory of concepts. I further propose that the same assumption carries over into alternative theories offered by proponents of the new consensus: pluralism, eliminativism, and hybrid theories. I put forth a sketch of an integrated model of concept formation and application, which rejects this shared assumption and satisfies the explanatory desiderata I discuss. I suggest that this model undermines the motivation for hybrid, pluralist, and eliminativist accounts of concepts. _1_ Introduction _2_ The Similarity-Based Approach and the Importance of Theory _2.1_ The similarity-based approach _2.2_ The selection desideratum _2.3_ Causal knowledge as satisfying the selection desideratum _3_ The Theory-Based Approach and the Importance of Similarity _3.1_ The theory-based approach _3.2_ The range desideratum _3.3_ Similarity as satisfying the range desideratum _4_ An Integrated Approach to Concepts _4.1_ An integrated model _4.2_ The integrated theory versus hybrid theories of concepts _5_ Conclusion.

Philosophers of logic are particularly interested in understanding the aims, epistemology, and methodology of logic. This raises the question of how the philosophy of logic should go about these enquires. According to the practice-based approach, the most reliable method we have to investigate the methodology and epistemology of a research field is by considering in detail the activities of its practitioners. This holds just as true for logic as it does for the recognised empirical and abstract sciences. If (...) we wish to systematically understand the aims and epistemology of logic, we are best placed achieving this by looking at what logicians do, rather than reflecting upon the nature of logic itself. In this entry, we outline the motivations for a practice-based approach towards the philosophy of logic and highlight its advantages over more “top-down” approaches, which attempt to infer conclusions about the nature of logic and its methodology on the basis of traditional assumptions about knowledge, metaphysics, or logic itself. We end by addressing several prominent concerns raised against the practice-based approach. (shrink)

ABSTRACT Linda Zagzebski’s exemplarist moral theory has gained traction in recent years as a valid approach to moral education. Insufficient attention has so far been paid to questions about who we should count among exemplary people to be emulated. In this paper, we make the case for considering the Swedish climate activist Greta Thunberg as one moral exemplar for the contemporary world. Since Thunberg is a controversial figure, we not only argue in positive terms why Thunberg would make (...) a good exemplar, but also respond to a number of objections that could be made to her exemplarity based on popular discussions. Our argument is however not limited to showing why Thunberg should be considered a moral exemplar. Through our discussion, we also exemplify the kind of critical discussions that in our view should be part of how exemplarism is utilized as a theory of moral education. (shrink)

Exemplarism – the view that exemplary people, whom we admire, are the bearers of our moral concepts – presents considerable challenges to the (widely-assumed) place of moral theory in how we learn to be moral. Exemplarism has been garnered by Amy Olberding to articulate a Confucian approach to moral learning. This paper extends Exemplarism by considering how it may be put into practice, based on a seminal Confucian text, the Analects of Confucius. To date, the majority of discussions (...) on Confucian ethics that have brought Confucian philosophy to the attention of Anglophone scholars tend to focus on conceptually-based matters. There remain questions regarding how these values may be inculcated and embodied in our moral lives. Central to our proposal is the practice of reflective observation (guan 觀), comprised by three integrated components: observation, evaluation, and emulation. Observing, reflectively, is important not only for an individual’s acculturation to existing norms and practices but also for how they may subsequently exercise some latitude over their moral practices. Our reflections offer a practical approach to Confucian moral learning. In doing so, we demystify moral learning in Confucianism and open up avenues for future cross-tradition dialogues on moral education. (shrink)

The debate over how best to characterize inflectional morphology has been couched largely in terms of the “dual-mechanism” approach described in Pinker (Words and rules: the ingredients of language, Basic Books, 1999) versus “single-mechanism” connectionist approaches derived from Rumelhart and McClelland (On learning past tenses of English verbs, MIT, 1986). There are, however, other single-mechanism approaches. The exemplar-based or analogical models of Daelemans et al. (TimBL: Tilburg Memory-Based Learner, version 4.3 reference guide, ILK, 2002) and Skousen (...) (Analogical modeling of language, Kluwer Academic, 1989) also model inflectional usage accurately within a single-mechanism. The most striking theoretical claim peculiar to these purely analogical models is that they do not posit any resident linguistic generalizations for processing language. Instead they process new instances of usage by comparing them systematically to remembered instances of previous usage. Based on a comparison of their Minimal Generalization Model with an adaptation of Nosofsky's (Journal of Mathematical Psychology 34: 393–418, 1990) Generalized Context Model, Albright and Hayes (Cognition 90: 119–161, 2003) argue that such purely analogical models are intrinsically inadequate for modeling the English past tense. This paper shows, however, that Skousen's (Analogical modeling of language, Kluwer Academic, 1989) Analogical Model performs as well as the Minimal Generalization Model. The implications of these results for cognitive linguistics are discussed. (shrink)

In the framework of judgment aggregation, we assume that some formulas of the agenda are singled out as premisses, and that both Independence (formula-wise aggregation) and Unanimity Preservation hold for them. Whether premiss-based aggregation thus defined is compatible with conclusion-based aggregation, as defined by Unanimity Preservation on the non-premisses, depends on how the premisses are logically connected, both among themselves and with other formulas. We state necessary and sufficient conditions under which the combination of both approaches leads to (...) dictatorship (resp. oligarchy), either just on the premisses or on the whole agenda. This framework is inspired by the doctrinal paradox of legal theory and arguably relevant to this field as well as political science and political economy. When the set of premisses coincides with the whole agenda, a limiting case of our assumptions, we obtain several existing results in judgment aggregation theory. (shrink)

This article explores the opportunities and challenges of using journalistic exemplars in the digital network to explicate intellectual virtues necessary for flourishing in that network. It seeks to advance media ethics theorizing by drawing together exemplar-based virtue theory, specifically Zagzebski’s Exemplarist Moral Theory, and work on intellectual virtues, in particular Baehr’s delineation of nine intellectual virtues. After a description of theoretical foundations, this article articulates an approach to identifying and explicating intellectual virtues through journalistic exemplars in the (...) digital network. It then applies this approach to the work of two journalists who have frequently and thoughtfully used social media. This exploratory analysis suggests the proposed approach holds promise for explication of individual virtues and identification of patterns among them. The approach also carries challenges and limitations, partly related to the nature and scope of virtual evidence for enactment of virtues by journalists. The authors suggest future research to minimize these limitations and continue advancing theorizing within this framework. (shrink)

In addressing the Lucretian symmetry problem, the content-based approach attends to the difference between the contents of the actual life and those of relevant possible lives of a person. According to this approach, the contents of a life with an earlier beginning would substantially differ from, and thus be discontinuous with, the contents of the actual life, whereas the contents of a life with the same beginning but a later death would be continuous with the contents of (...) the actual life. In this paper, I examine two versions of the content-based approach: the identity account and the preference account. The identity account holds that, in the sense of identity which is relevant to the evil of nonexistence, the subject of the actual life, though identical to the person in the life with a later death, is distinct from the subject of the life with an earlier beginning. The preference account maintains that, given one’s attachments to actual particulars, a life with an earlier beginning is not rationally preferable to one’s actual life, whereas a life with a later death is. I argue that each version of the content-based approach is implausible, while discussing some of the complications that face each of them. (shrink)

This paper concerns metaphysical indeterminacy and, in particular, the issue of whether quantum mechanics gives motivation for thinking the world contains it. In a previous paper (Darby G, Pickup M. Synthese 198:1685–1710, 2021), we have offered one way to think about metaphysical indeterminacy which we take to avoid some issues arising from certain features of quantum mechanics (such as the Kochen-Specker theorem). This approach has recently been criticised by Corti (Synthese, forthcoming), and we take this opportunity to respond. Our (...) paper will therefore reply to Corti’s argument, but we also take it as a case study in ‘naturalistic metaphysics’ and hence to contribute to a more general discussion of the relationship between philosophy of science and analytic metaphysics.

Finally I consider his objections to rival value-based models, and find those objections to (...) be less compelling than he makes them out to be. (shrink)

This paper is concerned with the uses of history in science. It focuses in particular on Anglo-American genetics and on university textbooks—where the canon of a science is consolidated, as the heterogeneous approaches and controversies of its practice are rendered unified for its reproduction. Tracing the emergence and eventual standardization of geneticists’ use of a case-based method of teaching in the 1920s–1950s, this paper argues that geneticists created historical environments in their textbooks—spaces in which students developed an understanding of (...) the laws of genetics through simulations of their discovery and use. Witnessing the unfolding of Mendel’s and Morgan’s experiments and performing genetic crosses on paper, students learned not only the rules that were explicitly taught as such, but also the experientially-based, tacit skills needed to find and follow these rules. This didactic system taught them how to go on when confronting new situations, and in doing so, provided geneticists with an important disciplinary tool, freeing the first steps of their student’s enculturation from the physical infrastructure of the laboratory.

This article gives a brief introduction to the MacArthur Competence Assessment Tool-Treatment (MacCAT-T) and critically examines its theoretical presuppositions. On the basis of empirical, methodological and ethical critique it is emphasised that the cognitive bias that underlies the MacCAT-T assessment needs to be modified. On the one hand it has to be admitted that the operationalisation of competence in terms of value-free categories, e.g. rational decision abilities, guarantees objectivity to a great extent; but on the other hand it bears severe (...) problems. Firstly, the cognitive focus is in itself a normative convention in the process of anthropological value-attribution. Secondly, it misses the complexity of the decision process in real life. It is therefore suggested that values, emotions and other biographic and context specific aspects should be considered when interpreting the cognitive standards according to the MacArthur model. To fill the gap between cognitive and non-cognitive approaches the phenomenological theory of personal constructs is briefly introduced. In conclusion some main demands for further research to develop a multi-step model of competence assessment are outlined. (shrink)

ArgumentSmallpox inoculation was introduced in Europe in the early eighteenth century and has been considered the first mass treatment of disease based on practical use of probability calculations and mathematical tools of computation. The article argues that these new approaches were deeply entangled with other rationalities, most emphatically that of exemplarity. Changes in inoculation methods around mid-century gradually changed the conceptualization of disease, seeing all cases as fundamentally equal, and thus making it more relevant to count them. Arithmetic changed (...) the ways of thinking about smallpox epidemics, but new ways of conceptualizing disease were vital to making it a matter of arithmetic at all. The article investigates what happened when numbers and figures were introduced into medical matters: Who did the figures really concern, and what types of argument were they fitted into? How were numbers transformed into metaphors, and how did quantitative argument work together with arguments from exemplarity? (shrink)

Teacher Education and the Pursuit of Wisdom takes its readers into the deep waters of investigating teaching not simply as a profession but as a precious "way of life." The author begins by investigating the nature of teaching as both an "active" and a "contemplative" endeavor and inquires into the resonance between the nature of teaching on the one hand and what has been said classically about genuine philosophizing on the other hand. Having laid the groundwork for students to be (...) able to recognize this intimate connection, readers are next challenged to take up the notion of teaching as a "way of life" in the pursuit of wisdom experimentally and to record their observations in a personalized journal format. Thorough explanations are provided concerning the value of journaling for self-knowledge, and exemplar texts by master journal writers are discussed. This book is designed for use as a primary textbook in philosophy of education courses. Instructors will find it helpful as a means to organize engaging classes at both the undergraduate and graduate levels for genuine philosophic practices and inquiry. It contains a well-defined program of work that is modelled upon the latest research concerning "authentic task design." Its rich experimental approach is replete with a broad array of learning tasks, assessment tools, and practices that are aligned with the competencies-based approach taken in most professional certification and BEd Programs.

Reasoners compare problems to prior cases to draw conclusions about a problem and guide decision making. All Case-Based Reasoning (CBR) employs some methods for generalizing from cases to support indexing and relevance assessment and evidences two basic inference methods: constraining search by tracing a solution from a past case or evaluating a case by comparing it to past cases. Across domains and tasks, however, humans reason with cases in subtly different ways evidencing different mixes of and mechanisms for these (...) components.In recent CBR research in Artificial Intelligence (AI), five paradigmatic approaches have emerged: statistically-oriented, model-based, planning/design-oriented, exemplar-based, and adversarial or precedent-based.

This article sheds light on moral education from an exemplarist perspective. Following Linda Zagzebski's Exemplarist Virtue Theory, we relate several fundamental exemplarist intuitions to the classical virtue ethical debate over the unity-disunity of the virtues, to endorse a pluralistic exemplar-based approach to moral education ("Empe"). After a few preliminary remarks, we argue that Empe amounts to defending "a prima facie" disunitarist perspective in moral theory, which admits both exemplarity in all respects (moral sainthood) and single-domain exemplarity (moral (...) heroism). Then, we evaluate the effectiveness of heroes and saints for moral education, according to four criteria derived from Empe. This analysis allows us to conclude that moral education should value both kinds of exemplars and, therefore, adopt weaker standards of exemplarity than the unitarist's ones. (shrink)

The emergence of signaling systems has been observed in numerous experimental and real‐world contexts, but there is no consensus on which (if any) shared mechanisms underlie such phenomena. A number of explanatory mechanisms have been proposed within several disciplines, all of which have been instantiated as credible working models. However, they are usually framed as being mutually incompatible. Using an exemplar‐based framework, we replicate these models in a minimal configuration which allows us to directly compare them. This reveals (...) that the development of optimal signaling is driven by similar mechanisms in each model, which leads us to propose three requirements for the emergence of conventional signaling. These are the creation and transmission of referential information, a systemic bias against ambiguity, and finally some form of information loss. Considering this, we then discuss some implications for theoretical and experimental approaches to the emergence of learned communication. (shrink)

This paper deals with the problem of derivational redundancy in scientific explanation, i.e. the problem that there can be extremely many different explanatory derivations for a natural phenomenon while students and experts mostly come up with one and the same derivation for a phenomenon (modulo the order of applying laws). Given this agreement among humans, we need to have a story of how to select from the space of possible derivations of a phenomenon the derivation that humans come up with. (...) In this paper we argue that the problem of derivational redundancy can be solved by a new notion of “shortest derivation”, by which we mean the derivation that can be constructed by the fewest (and therefore largest) partial derivations of previously derived phenomena that function as “exemplars”. We show how the exemplar-based framework known as “Data-Oriented Parsing” or “DOP” can be employed to select the shortest derivation in scientific explanation. DOP’s shortest derivation of a phenomenon maximizes what is called the “derivational similarity” between a phenomenon and a corpus of exemplars. A preliminary investigation with exemplars from classical and fluid mechanics shows that the shortest derivation closely corresponds to the derivations that humans construct. Our approach also proposes a concrete solution to Kuhn’s problem of how we know on which exemplar a phenomenon can be modeled. We argue that humans model a phenomenon on the exemplar that is derivationally most similar to the phenomenon, i.e. the exemplar from which the largest subtree(s) can be used to derive the phenomenon.

The literature on the impact of urban form design on travel behavior reveals mixed results. Instead of interpreting this finding as an insufficient basis for warranting action, this article suggests that a precautionary approach be introduced.

Even if trends, including the digitization of human life and society, peak oil and climate change (...) turn out to have smaller negative effects than is currently anticipated, we will be ahead with more livable and sustainable urban forms.

Among the main assumptions of the well-known principle-based method in bioethics, the ideal of consensus assumes central importance. Indeed, by proposing this method, Beauchamp and Childress offer a base for a practical agreement that can be reached starting from different moral perspectives: they defend the universality of the principles shared by the common-morality theories. The ideal of consensus based on the universal acceptability of the principles is criticized by a large number of authors, communitarians and feminists. They attack (...) the notion of universality in different ways: universal principles cannot yield any practical solution to ethical problems. The feminists in particular emphasize the relational, emotional involvement, and also the particular context ofeach situation, as central elements of any practical decision, rather than the cold detachment of the conformity to principles and norms. The case of abortion provides a good example of this position. (shrink)

This overview discusses the nature of perceptual illusions with particular reference to the theory that illusions represent the operation of a sensory code for which there is no meaningful ground truth against which the illusory percepts can be compared, and therefore there are no illusions as such. This view corresponds to the Bayesian theory that “illusions” reflect unusual aspects of the core strategies of adapting to the natural world, again implying that illusions are simply an information processing characteristic. Instead, it (...) is argued that a more meaningful approach to the field that we call illusions is the Ebbinghaus approach of comparing the illusory percept with a ground truth that is directly verifiable as aberrant by the observer in the domain of the illusory phenomenology. This concept of direct verifiability not only provides an operational definition of “illusion”; it also makes their interactive observation more effective and informative as to the perceptual processes underlying the illusory appearance. An expanded version of Gregory’s categorization of types of illusion is developed, and a range of classic and more recent illusions that illustrate the differences between these philosophical viewpoints is considered in detail. Such cases make it clear that the discrepancies from the measurable image structure cannot be simply regarded as idiosyncrasies of sensory coding, but are categorical exemplars of perceptual illusions. The widespread existence of such illusory percepts is indicative of the evolutionary limits of adaptive sensory coding. (shrink)

Concept representation is still an open problem in the field of ontology engineering and, more generally, of knowledge representation. In particular, the issue of representing “non classical” concepts, i.e. concepts that cannot be defined in terms of necessary and sufficient conditions, remains unresolved. In this paper we review empirical evidence from cognitive psychology, according to which concept representation is not a unitary phenomenon. On this basis, we sketch some proposals for concept representation, taking into account suggestions from psychological research. In (...) particular, it seems that human beings employ both prototype-based and exemplar-based representations in order to represent non classical concepts. We suggest that a similar, hybrid prototype-exemplar based approach could also prove useful in the field of knowledge representation technology. Finally, we propose conceptual spaces as a suitable framework for developing some aspects of this proposal. (shrink)

However, the majority of native South Africans appear to hold that since the post-apartheid South African society is heavily lopsided that the pursuit of social equality, especially by the natives who experience great economic disadvantage as a political goal, should be group-based in order to address comprehensively the social and economic ills of apartheid. This groupbased approach is challenged by European South Africans who argue that it introduces another form of inequality that places them at a disadvantage. I will analyze the arguments on both sides and attempt to justify the group-based approach in the light of the post-apartheid peculiar circumstances of native South Africans. Keywords: social equality, political goal, individual, group, South African society, apartheid. (shrink)

We present a novel methodology for calculating the improvements obtained in successive versions of biomedical ontologies. The theory takes into account changes both in reality itself and in our understanding of this reality. The successful application of the theory rests on the willingness of ontology authors to document changes they make by following a number of simple rules. The theory provides a pathway by which ontology authoring can become a science rather than an art, following principles analogous to those that (...) have fostered the growth of modern evidence-based medicine. Although in this paper we focus on ontologies, the methodology can be generalized to other sorts of terminology-based artifacts, including Electronic Patient Records. (shrink)

The recent literature has seen a burgeoning discussion of the idea that the overarching epistemic goal of education is the cultivation of the intellectual virtues. Moreover, there have been attempts to put this idea into practice, with virtue-led educational interventions in schools, universities, and even prisons. This paper explores the question of whether—and, if so, to what degree—such intellectual virtue-based approaches to education are essentially social. The focus in this regard is on the role of intellectual exemplars within this (...) approach, and in particular the extent to which direct social interaction with such exemplars is crucial to the implementation of this educational methodology.

A cognitive assessment strategy that is not limited to examining a set of summary test scores may be more helpful for early detection of emergent illness such as Alzheimer’s disease (AD) and may permit a better understanding of cognitive functions and dysfunctions in those with AD and other dementia disorders. A revisit of the work already undertaken by Kaplan and colleagues using the Boston Process-Approach provides a solid basis for identifying new opportunities to capture data on neurocognitive processes, test-taking (...) strategies and response styles. Thus, this critical review will combine traditional process-based assessment strategies with support provided or offered by newer technologies that have the potential to add value to data collection and interpretation. There is now considerable interest in neuropsychological test administration using computer/digital technology, both in research and in clinical settings. To add value, any computerized version of an existing cognitive test should respect the administration procedure for which normative data were obtained, should be time-saving in terms of scoring and interpretation, and should, we argue, facilitate gathering information about the processes and strategies followed in test completion. This article will offer an overview of the steps needed when implementing computerization of neuropsychological tests using a Process-Based Approach (PBA) to these technology-based adaptations and will discuss further developments in this area by linking it to future technological developments that may be possible in the area of neuropsychological assessment. Additionally, an overview of neuropsychological tests that may benefit from computerization will be presented, together with suggestions on the specific processes, strategies and features that may be captured with the aid of such computerization. Finally, hypotheses on how virtual reality could be an asset for the future of the PBA to neuropsychological assessment will also be discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.4 (2003) 568-569 [Access article in PDF] James P. Scanlan. Dostoevsky the Thinker. Ithaca, NY: Cornell University Press, 2002. Pp. xiii + 251. Cloth, $29.95. Important works on Dostoevsky's life and thought abound, but James Scanlan offers the first comprehensive treatment and evaluation of Dostoevsky as a philosophical thinker. Scanlan uses Dostoevsky's thousands of letters, essays, and "capacious notebooks" (3), as well as (...) his literary work, to analyze systematically Dostoevsky's philosophical worldview and to argue for its coherence. Scanlan's commitment to careful scholarship is apparent throughout, including his translations of the texts. A philosopher himself, Scanlan contextualizes Dostoevsky's work in relation to traditional philosophers, including Descartes, Kant, and Kierkegaard. The result is a balanced, rich, and provocative treatment that also suggests new interpretations of some of Dostoevsky's literary works.If Bakhtin is right to describe Dostoevsky's novels as "polyphonic," how does one ascertain their author's position? Scanlan grants the challenges of approaching Dostoevsky as a philosopher. Nineteenth-century Russian thinkers rarely identified with particular philosophical schools, and Dostoevsky never thought of himself as a philosopher. Yet Dostoevsky was intensely interested in philosophy, and Scanlan argues that Dostoevsky's characters serve as surrogates for competing philosophical positions. Scanlan also reminds readers of Dostoevsky's often-neglected nonfiction works and weaves masterfully the nonfiction and the literature to support his argument.Echoing Bakhtin, Scanlan labels Dostoevsky's methodology "dialogical in style, monological in substance" (4). Doing so effectively rejects critical perspectives that suggest the author held contradictory positions. For Scanlan, Dostoevsky's dialectical method resulted from his preoccupation with combating others' ideas, implied by his frequent use of reductio ad absurdum arguments. Dostoevsky "sought to establish his own positions by demonstrating the failure of their antitheses" (231). Not only does Scanlan persuasively demonstrate the consistency of Dostoevsky's philosophical commitments, he also challenges the appropriation of Dostoevsky by existentialists as an "irrationalist," despite Dostoevsky's "convincing portrayals of human irrationality" and skepticism concerning rationality's powers (5).Scanlan examines Dostoevsky's vision of Christianity that included a strict binary of matter and spirit, and a rejection of rational egoism and mechanism (termed "nihilism"). Dostoevsky's positive deontologism, his "law of love" (with Christ as exemplar) was, for Dostoevsky, necessary to overcome the "law of personality," and conscience grounded in Christian love was the basis for salvation. Scanlan persuasively argues that Dostoevsky, if irrationalist, belongs more with Kant than Kierkegaard in viewing rationality as limited but not to be rejected wholesale. Scanlan uses this analysis to ground a provocative new reading of Notes from Underground.Scanlan also explores the connectedness of Dostoevsky's ethics and aesthetics in Dostoevsky's insistence that artists should create moral beauty beyond the purely aesthetic or cognitive. Much has been written about Dostoevsky's aesthetics, but Scanlan exposes its logical grounding in Dostoevsky's rejection of the subjective utilitarian aesthetics of Chernyshevsky and the radical materialism of Dobrolyubov. For Dostoevsky, the need for [End Page 568] beauty and creativity is intrinsic to human nature, and art serves an epistemological function that gestures toward reality, not as a "mindless photographer" (140) but as a cognitive vision penetrating "the core of his subject" (141). Dostoevsky also justified his use of the anomalous, noting that the exceptional might be "an avenue of access to the universal" (143).Dostoevsky's "dream of a community of perfect Christian brotherhood and love" (160) grounds Scanlan's examination of Dostoevsky's sociopolitical philosophy and his rejection of the critical view that Dostoevsky's politics radically changed over time. Though Scanlan agrees with biographers that Dostoevsky despised the "moral blight" (169) of serfdom, he argues that Dostoevsky's vision of Christian society permitted social stratification so long as service to masters was voluntary, cooperative, and rational. This analysis makes clear the distance between Dostoevsky and Western liberal political theorists.For Dostoevsky, society based on universal Christian love is the only acceptable "socialism," and the last part of Scanlan's work analyzes Dostoevsky's nationalism and its relation to his attacks on socialism.

How can different individuals' probability functions on a given sigma-algebra of events be aggregated into a collective probability function? Classic approaches to this problem often require 'event-wise independence': the collective probability for each event should depend only on the individuals' probabilities for that event. In practice, however, some events may be 'basic' and others 'derivative', so that it makes sense first to aggregate the probabilities for the former and then to let these constrain the probabilities for the latter. We formalize (...) this idea by introducing a 'premise-based' approach to probabilistic opinion pooling, and show that, under a variety of assumptions, it leads to linear or neutral opinion pooling on the 'premises'. This paper is the second of two self-contained, but technically related companion papers inspired by binary judgment-aggregation theory. (shrink)

In this article, I provide a new account of the basis of medical researchers' ancillary care obligations. Ancillary care in medical research, or medical care that research participants need but that is not required for the validity or safety of a study or to redress research injuries, is a topic that has drawn increasing attention in research ethics over the last ten years. My view, the relationship-based approach, improves on the main existing theory, Richardson and Belsky's ‘partial-entrustment model’, (...) by avoiding its problematic restriction on the scope of health needs for which researchers could be obligated to provide ancillary care. Instead, it grounds ancillary care obligations in a wide range of morally relevant features of the researcher-participant relationship, including the level of engagement between researchers and participants, and weighs these factors against each other. I argue that the level of engagement, that is, the duration and intensity of interactions, between researchers and participants matters for ancillary care because of its connection to the meaningfulness of a relationship, and I suggest that other morally relevant features can be grounded in researchers' role obligations.

Traditionally the study of computer ethics involves taking students who are not philosophically trained, exposing them to action-guiding theories, presenting them with the codes of ethics of several companies and professional organizations and asking them to make ethical decisions in scenario-based cases. This approach is deliberately action-based and focuses on doing. "What would you do?" is the traditional question we ask our students. While this pedagogical methodology forces them to examine situations and argue from a particular point (...) of view, it does little to influence their character. They see the utilitarian or deontologist as someone other than themselves. There seems to be very little internalization of these action-based theories.Virtue Ethics offers character-forming theory that has been more successful with my students than the action-based theories of computer ethics texts. Why? Virtue Ethics is directed toward character development. The focus is on being rather than doing. It presents a good heuristic or approach to the problem of moral agency. Virtue ethics offers a way of teaching self-reflection through narratives that focus on core values, heroes and moral exemplars. It is grounded in practical wisdom. It is experiential, learning to care about the self, others, the community, living the good life, flourishing and striving for moral excellence. It offers a model for the development of character and personal ethics which will lead to professional ethics. Yet, the strict Virtue Ethics espoused by Aristotle has its limitations. This paper will explore the need for a more integrative approach to contemporary moral theory, one that may be found by revisiting the virtues through the works of Aristotle and Kant. It will offer insight into translating theory into practice for students of computer science and information technology. (shrink)

My view, the relationship‐based approach, improves on the main existing theory, Richardson and Belsky's ‘partial‐entrustment model’, (...) by avoiding its problematic restriction on the scope of health needs for which researchers could be obligated to provide ancillary care.

Scientists imagine constantly. They do this when generating research problems, designing experiments, interpreting data, troubleshooting, drafting papers and presentations, and giving feedback. But when and how do scientists learn how to use imagination? Across 6 years of ethnographic research, it has been found that advanced career scientists feel comfortable using and discussing imagination, while graduate and undergraduate students of science often do not. In addition, members of marginalized and vulnerable groups tend to express negative views about the strength of their (...) imaginations and the general usefulness of imagination in science. After introducing these findings and discussing the typical relationship between a scientist and their imagination across a career, we argue that reducing the number or power of active imaginations in science is epistemically counterproductive. We suggest several ways to bring imagination back into science in a more inclusive way, especially through courses on imagination for scientists, good role models, and exemplar-based learning.

Some bioethicists have proposed a legalized market in human organs as a solution to transplant waiting lists and global poverty. Solutions to organ procurement problems that are solely market-based would unfairly shift the burdens of medical procedures onto developing nations. Market advocates base their claims on the understanding of organs as property, a position that should be problematized. Instrumentalizing people in this way is part of the broader commodification of animals and the environment. Combating the market mentality requires a (...) return to the holistic view of bioethics that led to the founding of the field. (shrink)
