Computational models will play an important role in our understanding of human higher‐order cognition. How can a model's contribution to this goal be evaluated? This article argues that three important aspects of a model of higher‐order cognition to evaluate are (a) its ability to reason, solve problems, converse, and learn as well as people do; (b) the breadth of situations in which it can do so; and (c) the parsimony of the mechanisms it posits. This article argues that fits of (...) models to quantitative experimental data, although valuable for other reasons, do not address these criteria. Further, using analogies with other sciences, the history of cognitive science, and examples from modern‐day research programs, this article identifies five activities that have been demonstrated to play an important role in our understanding of human higher‐order cognition. These include modeling within a cognitive architecture, conducting artificial intelligence research, measuring and expanding a model's ability, finding mappings between the structure of different domains, and attempting to explain multiple phenomena within a single model.

The distinction between literal and figurative use is well-known and embedded in ‘folk linguistics’. According to folk linguistics, figurative uses deviate from literal ones. But recent work on lexical modulation and polysemy shows that meaning deviation is ubiquitous, even in cases of literal use. Hence, it has been argued, the literal/figurative distinction has no value for theorising about communication. In this paper, we focus on metaphor and argue that here the literal–figurative distinction has theoretical importance. The distinction between literal and (...) metaphorical needs to be captured by our account of communication because literal uses transmit information in a way that metaphorical ones do not. We argue that there is a way to explain the literal/metaphorical distinction that preserves the core of the folk-linguistic idea and gives the distinction theoretical relevance. We propose that literal uses of a word are made with the intention to conform to an established practice of use, while metaphorical uses do not so conform, but depend on this pre-existing practice. Our account can deal with data that are problematic for other theories. A further advantage is that it extends naturally to other non-literal uses of words, including metonymy. (shrink)

The field of cognitive modeling has progressed beyond modeling cognition in the context of simple laboratory tasks and begun to attack the problem of modeling it in more complex, realistic environments, such as those studied by researchers in the field of human factors. The problems that the cognitive modeling community is tackling focus on modeling certain problems of communication and control that arise when integrating with the external environment factors such as implicit and explicit knowledge, emotion, cognition, and the cognitive (...) system. These problems must be solved in order to produce integrated cognitive models of moderately complex tasks. Architectures of cognition in these tasks focus on the control of a central system, which includes control of the central processor itself, initiation of functional processes, such as visual search and memory retrieval, and harvesting the results of these functional processes. Because the control of the central system is conceptually different from the internal control required by individual functional processes, a complete architecture of cognition must incorporate two types of theories of control: Type 1 theories of the structure, functionality, and operation of the controller, and type 2 theories of the internal control of functional processes, including how and what they communicate to the controller. This book presents the current state of the art for both types of theories, as well as contrasts among current approaches to human-performance models. It will be an important resource for professional and student researchers in cognitive science, cognitive-engineering, and human-factors.Contributors: Kevin A. Gluck, Jerry T. Ball, Michael A.

The measurement of diagnostic accuracy is an important aspect of the evaluation of diagnostic tests. Sometimes, medical researchers try to discover the set of observations that are most accurate of all by directly inspecting diseased and not-diseased patients. This method is perhaps intuitively appealing, as it seems a straightforward empirical way of discovering how to identify diseased patients, which amounts to trying to correlate the results of diagnostic tests with disease status. I present three examples of researchers who try to (...) produce definitive diagnostic criteria by directly inspecting diseased and not diseased patients. Despite this method’s intuitive appeal, I will argue that it is impossible to carry out. Before researchers can inspect these patients to discover definitive diagnostic criteria, they must be able to distinguish diseased and not-diseased patients; and they do not know how to do this, because this is what they are trying to discover. I suspect the intuitive appeal of directly inspecting patients makes this difficult to appreciate. To counter this difficulty, I present this problem as a manifestation of ‘Meno’s paradox’, which was described in classical antiquity, and of ‘the problem of nomic measurement’, described more recently. Considering these philosophical problems may help researchers address the methodological issues they face when evaluating diagnostic tests. (shrink)

The orthodox reading of Peter Strawson's “Freedom and Resentment” tends to hide interesting elements of its underlying argumentative structure. Recognition of a distinction Strawson draws between two classes of reactive attitudes raises a question about how the distinct discussions are related. The orthodox reading seems to assume the only relevant difference between the two classes is one of perspective; however, this reading obscures the analogical nature of Strawson's argument and encourages a conflation of distinct elements within that argument. In this (...) paper, I show that an analogical interpretation of the relationship between the distinct classes of attitudes reveals differences between them that have interesting implications for the secondary literature that has developed around Strawson's famous essay.

This book advocates a radical shift of concern in philosophical, historical, and sociological studies of the sciences, and explores the consequences of such a shift. The historically-oriented first part of the work deals with the ways in which ranges of questions become real and cease to be real for communities of inquirers. The more philosophically-oriented second part of the work introduces the notion of absolute reality of questions, and addresses doubt about the claims of the sciences to have accumulated absolutely (...) real questions. It is argued that recent studies in the sociology and social history of the science pose strong challenges to the sciences by revealing how appeals to authority, vested interests, and rhetorical and aesthetic sensibilities play substantial roles in the practices of the sciences. The final chapter defends the pragmatic stance of the work, and of its companion, The Fortunes of Inquiry, and draws morals about the roles of criticism and reflection in the philosophy of science and in the sciences themselves.

A clearly written, authoritative introduction to Taylor's work.

Postmodernism and poststructuralism challenge fundamental positions in social theory. This book sets out some of the components of a postmodern social theory of health and healing, deriving from theorists including Derrida, Deleuze and Guattari, Foucault, Cixous and Kristeva. Nicholas J. Fox observes that the knowledge of the medical profession about the body, illness and health supplies the basis for medical dominance. The body of the patient is inscribed by discourses of professional `care,' an interaction which subjectifies the patient. Fox (...) explores the character of this power - and how it may be, and is, resisted. The book illustrates with detailed examples how the organization of health care and the caring relationship itself are sites for this contestation of power. Elements of feminist theory, and Derridean concepts of diffrance and intertextuality, supply the framework for the politics and ethics of the postmodern position on health. Deleuze and Guattari's radical challenge to psychoanalysis and familial repetitions within the healer/patient contact allows a re-reading of central ideas in medical sociology. While focusing upon the possibilities of postmodern social theory, the book demands a reappraisal of issues of structure, identity and knowledge in modernist medical sociology. Modernist sociology, Fox suggests, has been complicit in the creation of `the patient,' and of 'health' and 'illness.' Written with an emphasis on accessibility, this book explores the practical consequences of postmodern theory as well as familiarizing the reader with the concepts of postmodernism. (shrink)

Even though medics in the present day may think that clinical pathology is derived from normal physiology, I argue here that this is not necessarily the case. Historically, physiology may have been derived from clinical pathology. After deriving physiological knowledge like this, medics can reverse the conceptual priority, to make believe that physiological knowledge is at the foundation of medical practice. This implies that supposedly objective physiological knowledge can be influenced by the evaluative judgements made to define practical concepts of (...) clinical pathology. I argue for this view using the history of the disease heart failure, drawing on an argument made by Georges Canguilhem. (shrink)

There is increasing evidence for epigenetically mediated transgenerational inheritance across taxa. However, the evolutionary implications of such alternative mechanisms of inheritance remain unclear. Herein, we show that epigenetic mechanisms can serve two fundamentally different functions in transgenerational inheritance: (i) selection-based effects, which carry adaptive information in virtue of selection over many generations of reliable transmission; and (ii) detection-based effects, which are a transgenerational form of adaptive phenotypic plasticity. The two functions interact differently with a third form of epigenetic information transmission, (...) namely information about cell state transmitted for somatic cell heredity in multicellular organisms. Selection-based epigenetic information is more likely to conflict with somatic cell inheritance than is detection-based epigenetic information. Consequently, the evolutionary implications of epigenetic mechanisms are different for unicellular and multicellular organisms, which underscores the conceptual and empirical importance of distinguishing between these two different forms of transgenerational epigenetic effect.

This paper advocates explicitness about the type of entity to be considered as content- bearing in connectionist systems; it makes a positive proposal about how vehicles of content should be individuated; and it deploys that proposal to argue in favour of representation in connectionist systems. The proposal is that the vehicles of content in some connectionist systems are clusters in the state space of a hidden layer. Attributing content to such vehicles is required to vindicate the standard explanation for some (...) classificatory networks’ ability to generalise to novel samples their correct classification of the samples on which they were trained.

Elselijn Kingma argues that Christopher Boorse’s biostatistical theory (the BST) does not show how the reference classes it uses are objective and naturalistic. Recently, philosophers of medicine have attempted to rebut Kingma’s concerns. I argue that these rebuttals are theoretically unconvincing, and that there are clear examples of physicians adjusting their reference classes according to their prior knowledge of health and disease. I focus on the use of age-adjusted reference classes to diagnose low bone mineral density in children. In addition (...) to using the BST’s age, sex, and species, physicians also choose to use other factors to define reference classes, such as pubertal status, bone age, body size, and muscle mass. I show that physicians calibrate the reference classes they use according to their prior knowledge of health and disease. Reference classes are also chosen for pragmatic reasons, such as to predict fragility fractures. (shrink)

Fodor’s radical concept nativism flowed from his view that hypothesis testing is the only route to concept acquisition. Many have successfully objected to the overly-narrow restriction to learning by hypothesis testing. Existing representations can be connected to a new representational vehicle so as to constitute a sustaining mechanism for a new representation, without the new representation thereby being constituted by or structured out of the old. This paper argues that there is also a deeper objection. Connectionism shows that a more (...) fundamental assumption underpinning the debate can also be rejected: the assumption that the development of a new representation must be explained in content-involving terms if innateness is to be avoided. -/- Fodor has argued that connectionism offers no new resources to explain concept acquisition: unless it is merely an uninteresting claim about neural implementation, connectionism’s defining commitment to distributed representations reduces to the claim that some representations are structured out of others (which is the old, problematic research programme). Examination of examples of representational development in connectionist networks shows, however, that some such models explain the development of new representational capacities in non-representational terms. They illustrate the possibility of representational development that is not explicable-by-content. Connectionist representations can be distributed in an important sense, which is incompatible with the assumption of explanation-by-content: they can be distributed over non-representational resources that account for their development. Rejecting the assumption of explanation-by-content thereby opens up a more radical way of rejecting Fodor’s argument for radical concept nativism. (shrink)

The purpose of this paper is to confront a well-known problem in interreligious engagement in European institutions, namely the tendency to exclude contributions that do not conform to certain European expectations. It diagnoses problems produced not only by the problem but by certain solutions to it, and to propose in outline an alternative approach. Chief among these problems is the imperative that members of traditions articulate their deepest moral commitments, in order to secure a common moral ground. This imperative has (...) the unintended but drastic effect of excluding important voices in dialogue. Drawing on the figures of Cordelia (in Shakespeare’s King Lear) and Antigone (in Sophocles’ Antigone) it is argued that forced articulation distorts its objects. The theoretical framework of discussion is drawn from Hegel, Schelling, and Adorno as in interpreted by Alasdair MacIntyre, Charles Taylor, and Andrew Bowie. The originality of the argument is the use of aesthetic theory in German philosophy to inform a critique of attempts to make morality central to interreligious engagement. (shrink)

Humans have a much longer juvenile period (weaning to first reproduction, 14 or more years) than their closest relatives (chimpanzees, 8 years). Three explanations are prominent in the literature. (a) Humans need the extra time to learn their complex subsistence techniques. (b) Among mammals, since length of the juvenile period bears a constant relationship to adult lifespan, the human juvenile period is just as expected. We therefore only need to explain the elongated adult lifespan, which can be explained by the (...) opportunity for older individuals to increase their fitness by providing for grandchildren. (c) The recent model by Kaplan and colleagues suggests that longevity and investment in "embodied capital" will coevolve, and that the need to learn subsistence technology contributed to selection for our extended lifespan.We report experiments designed to test the first explanation: human subsistence technology takes many years to learn, and spending more time learning it gives reproductive benefits that outweight lost time. Taking away some of this time should lead to deficits in efficiency. We paid Hadza foragers to participate in tests of important subsistence skills. We compared efficiency of males and females at digging tubers. They differ greatly in time spent practicing digging but show no difference in efficiency. Children who lost "bush experience" by spending years in boarding school performed no worse at digging tubers or target archery than those who had spent their entire lives in the bush. Climbing baobab trees, an important and dangerous skill, showed no change with age among those who attempted it. We could show no effects of practice time.These findings do not support what we label "the practice theory," but we discuss ways in which the theory could be defended; for example, some as-yet-untested skill may be greatly impaired by loss of a few years of the juvenile period. Our data also show that it is not safe to assume that increases in skill with age are entirely due to learning or practice; they may instead be due to increases in size and strength. (shrink)

The question of whether non-human animals are conscious is of fundamental importance. There are already good reasons to think that many are, based on evolutionary continuity and other considerations. However, the hypothesis is notoriously resistant to direct empirical test. Numerous studies have shown behaviour in animals analogous to consciously-produced human behaviour. Fewer probe whether the same mechanisms are in use. One promising line of evidence about consciousness in other animals derives from experiments on metamemory. A study by Hampton (Proc Natl (...) Acad Sci USA 98(9):5359–5362, 2001 ) suggests that at least one rhesus macaque can use metamemory to predict whether it would itself succeed on a delayed matching-to-sample task. Since it is not plausible that mere meta-representation requires consciousness, Hampton’s study invites an important question: what kind of metamemory is good evidence for consciousness? This paper argues that if it were found that an animal had a memory trace which allowed it to use information about a past perceptual stimulus to inform a range of different behaviours, that would indeed be good evidence that the animal was conscious. That functional characterisation can be tested by investigating whether successful performance on one metamemory task transfers to a range of new tasks. The paper goes on to argue that thinking about animal consciousness in this way helps in formulating a more precise functional characterisation of the mechanisms of conscious awareness. (shrink)

There is a debate about the possibility of mind-uploading – a process that purportedly transfers human minds and therefore human identities into computers. This paper bypasses the debate about the metaphysics of mind-uploading to address the rationality of submitting yourself to it. I argue that an ineliminable risk that mind-uploading will fail makes it prudentially irrational for humans to undergo it.

If a speaker selflessly asserts that p, the speaker (1) has good evidence that p is true, (2) asserts that p on the basis of that evidence, but (3) does not believe that p. Selfless assertions are widely thought to be acceptable, and therefore to pose a threat to the Knowledge Norm of Assertion. Advocates for the Knowledge Norm tend to respond to this threat by arguing that there are no such things as selfless assertions. They argue that those who (...) appear to be selfless asserters either: believe what they assert, perform a speech act other than assertion, or assert a proposition other than the one that they seem to. I argue that such counterarguments are unsuccessful. There really are selfless assertions. But I also argue that they are no threat to the Knowledge Norm. There is a good case to be made that knowledge does not require belief. And if it does not, then the fact that some selfless assertions are appropriate does not tell against the Knowledge Norm. Indeed, I argue that selfless asserters know the propositions that they assert to be true. (shrink)

Leibniz est-il devenu phénoménaliste pendant ses années dernières ? Contre Furth et Loeb, ce travail rend une réponse négative à cette question. Quoique Leibniz a caressé les idées phénoménalistes, il ne les a jamais vraiment acceptées ; au contraire, il soutient une autre thèse réductioniste, c'est-à-dire que les corps sont des agrégats des monades. Cependant, cette conclusion entraîne ses propres difficultés, car à certains égards, la doctrine phénoménaliste paraît plus satisfaisante que l'option concurrante. On soutient que la répugnance leibnizienne à (...) accepter le phénoménalisme doit s'expliquer par son dessein de concilier la monadologie et la physique. (shrink)

A common theme in the historiography of Greek ethics says that modern ethics is characterized by imperative notions such as ‘duty’—and with a Judeo‐Christian notion of imperatives or commands issued by god—whereas ancient ethics supposedly deals mainly with ‘attractive notions such as ‘good’ and ‘virtue’. This thought is often juxtaposed with the idea that imperative notions betoken a conflict between one's duty and one's good, because an imperative seems to be required only to command people to do what they do (...) not wish to do, which is felt to be inappropriate to the supposed eudaimonism of Greek ethics. In fact Greek ethics makes substantial use of imperative notions, and does not attempt to show that attractive notions are more basic or preferable in ethics. (shrink)

Thus far it has been shown that Greek ethics is not as different from modern ethics as is commonly held, and that we cannot oppose a harmonizing Greek ethical outlook with a modern view that involves a conflict between happiness and adherence to ethical standards. Greek ethics has universalistic features—though they are different from the egalitarian characteristics of modern positions and do not focus on the notion of benevolence in the way that modern ethics does—and it mostly distinguishes self‐referential and (...) non‐self‐referential aims. Moreover, there is not in any case such a thing as a monolithic ethical view of ‘the Greeks’, and the idea of a straightforward contrast between ‘ancient’ and ‘modern’ ethics is best avoided.

Accounts of language evolution have largely suffered from a monolingual bias, assuming that language evolved in a single isolated community sharing most speech conventions. Rather, evidence from the small-scale societies who form the best simulacra available for ancestral human communities suggests that the combination of small societal scale and out-marriage pushed ancestral human communities to make use of multiple linguistic systems. Evolutionary innovations would have occurred in a number of separate communities, distributing the labor of structural invention between populations, and (...) would then have been pooled gradually through multilingually mediated horizontal transfer to produce the technological package we now regard as a natural ensemble.

The still dominant virtue-ethical account of right action claims that an action is right just in case a virtuous agent would perform it. Because this account arguably fails to capture what makes actions right, virtue ethicists are well-advised to consider alternatives. I argue that a target-centered account, if suitably developed, succeeds in capturing what makes actions right. First, I explain why a target-centered account shows initial promise in capturing what makes actions right and present an interpretation of the account as (...) developed by its creator, Christine Swanton. Second, I argue that Swanton's and other prominent virtue ethicists’ views of virtuous action are defective, partly in virtue of accepting reasons of the wrong kind for an action’s being virtuous or vicious in respect to a virtue. My arguments, if successful, motivate an alternative version of the target-centered account. Finally, I contribute to the development of such an alternative by sketching a view of virtuous action that avoids the aforementioned defects and thereby promises full success in capturing what makes actions right.

Writing in the Business and Politics, Santos and Laczniak (Business and Politics 14(1) 2012) formulated a normative, ethical approach to be followed when marketers e ngage impoverished market segments. It is labeled the integrative justice model (IJM). As noted below, that approach called for authentic engagement, co-creation, and customer interest representation, among other elements, when transacting with vulnerable market segments. Basically, the IJM derived certain operational virtues, implied by moral philosophy, to be used when marketing to the poor. But this (...) well-intentioned approach raises a significant “So what?” question. Are such sentiments anything but lofty aspirations for idealists or are there steps to be taken by society and business managers of goodwill to make the adaptation of the IJM by corporations more likely and pragmatic? This paper begins to layout a roadmap that shows “how and why” the IJM might more likely be vitalized. The crux, as described below, is found in the transformational justice dimensions that are embedded in institutions (and supporting institutional arrangements); such external institutions provide a “power” impetus to assure the ethical rights claims that impoverished consumers have owed to them. In this way, the ideal exchange characteristics for bottom (or base) of the pyramid (BoP) markets argued for in the IJM can become actively transformational. The main contribution of this paper is that it begins to chart out the institutional system elements that need to exercise power in order to deliver a “fairer” marketplace for BoP consumers.

A bad philosophy of inquiry, built into the intellectual/institutional structure of universities round the world, betrays both reason and humanity.

The paper contrasts two approaches to the analysis of hope: one that takes its departure from a view broadly shared by Hobbes, Locke and Hume, another that fits better with Aquinas's definition of hope. The former relies heavily on a sharp distinction between the cognitive and conative aspects of hope. It is argued that while this approach provides a valuable source of insights, its focus is too narrow and it rests on a problematic rationalistic psychology. The argument is supported by (...) a discussion of hope understood as a stance and by a consideration of the phenomenological contrast between expectation and anticipation. The paper concludes with some reflections on the relation between hope and illusion and the idea of responsible hope. (shrink)
