Aim: Participation in classroom physical activity breaks may improve children’s cognition, but few studies have involved adolescents. The primary aim of this study was to examine the effects of classroom-based resistance training with and without cognitive training on adolescents’ cognitive function.Methods: Participants were 97 secondary school students. Four-year 10 classes from one school were included in this four-arm cluster randomized controlled trial. Classes were randomly assigned to the following groups: sedentary control with no cognitive training, sedentary with cognitive training, resistance (...) training without cognitive training, and resistance training with cognitive training. Sessions varied in levels of both cognitive demand and resistance training and were administered three times per week for 4 weeks. Inhibition, cognitive flexibility, episodic memory, on-task behavior, and muscular fitness were assessed at baseline and post-test. Linear mixed models were used to examine changes within and between groups.Results: In comparison with the control group, episodic memory improved significantly in the resistance training without cognitive training group. There were no group-by-time effects for inhibition or cognitive flexibility. Classroom activity breaks both with and without cognitive demand improved participants’ on-task behavior in comparison with the control and sedentary group. The resistance training programs did not lead to improvements in muscular fitness.Conclusion: Participation in body weight resistance training without cognitive training led to selective improvements in episodic memory. No training effects were found for inhibition or cognitive flexibility. A longer study period may be necessary to induce improvements in muscular fitness and associated changes in inhibition and cognitive flexibility.Clinical Trial Registration:https://www.anzctr.org.au/ACTRN12621001341819.aspx, Australian New Zealand Clinical Trials Registry—ACTRN12621001341819.

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.

Economics takes an individualistic approach to human behaviour. This is reflected in the use of 'contingent valuation' surveys to conduct cost benefit analysis for economic policy evaluation. An individual's valuation of a policy is assumed to be unaffected by the burdens it places on others. We report a survey experiment to test this supposition in the context of climate change policy. Willingness to pay for climate change mitigation was higher when richer individuals were to bear higher costs than when, as (...) is usual, no explicit information was provided about cost distribution. This result is inconsistent with the usual interpretation of contingent valuation data. It also suggests that the data may be biased indicators of policy acceptance. Additional survey questions suggest that a collective mode of reasoning is common. (shrink)

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.

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)

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

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.

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)

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)

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)

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)

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)

Sedlár and Vigiani [18] have developed an approach to propositional epistemic logics wherein (i) an agent’s beliefs are closed under relevant implication and (ii) the agent is located in a classical possible world (i.e., the non-modal fragment is classical). Here I construct first-order extensions of these logics using the non-Tarskian interpretation of the quantifiers introduced by Mares and Goldblatt [12], and later extended to quantified modal relevant logics by Ferenz [6]. Modular soundness and completeness are proved for constant domain semantics, (...) using non-general frames with Mares–Goldblatt truth conditions. I further detail the relation between the demand that classical possible worlds have Tarskian truth conditions and incompleteness results in quantified relevant logics. (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)

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.

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.

ON MILLIKAN offers a concise, yet comprehensive, introduction to this philosopher's most important ideas.

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.

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)

Adam Smith’s formal legacy to posterity consisted of meticulously revised editions of his two published works, The Theory of Moral Sentiments and The Wealth of Nations; long-standing plans for treatises on Jurisprudence, Rhetoric, and the Fine Arts were abandoned on the grounds that there was no time to complete them. This chapter discusses Smith oeuvre as component parts of an unrealized plan to develop a Science of Man on experimental principles. Smith’s introduction to this grand projet as a student is (...) explored and the influence of Hutcheson and Hume is emphasized as is the fact that Smith developed both the published and unpublished components of his Science of Man simultaneously. The question of the meaning Smith attached to ‘science’ is a continuing theme of the chapter. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Free Will and the Rebel Angels in Medieval Philosophy by Tobias HoffmannNicholas OgleFree Will and the Rebel Angels in Medieval Philosophy by Tobias Hoffmann (Cambridge: Cambridge University Press, 2021), xiv + 292 pp.Modern readers are often perplexed by the frequency and rigor with which angels are discussed in medieval philosophical texts. To the untrained eye, it may seem as if debates concerning the various properties and abilities of (...) purely spiritual beings are the epitome of Scholastic extravagance, which can be safely disregarded—if not outright ridiculed—as a fanciful diversion from more essential philosophical concerns. The truth, of course, is that angelological reflection gave rise to some of the most original philosophical ideas of the Middle Ages, from Anselm's two affectiones of the will to Aquinas's "real distinction" between essence and existence. Far from being an idiosyncratic theological addendum to an already complete philosophical system, consideration of the angelic nature was in fact a central component of medieval philosophy, without which certain crucial metaphysical and psychological insights might not have occurred. This often-neglected truth is given detailed expression in Tobias Hoffmann's Free Will and the Rebel Angels in Medieval Philosophy, which explores how philosophical investigation into the fall of the angels—that is, the hypothesis of an evil choice made by rational beings under optimal psychological conditions—helped bring about significant advances in medieval debates about free will. Focusing on the century immediately following the reception of Aristotle's action theory in the Latin West (from roughly the 1220s to the 1320s), Hoffmann examines how theological claims regarding angelic sin influenced medieval thinkers as they sought to reconcile the intellectualism of Aristotelian moral psychology with their understanding of free will as the power to choose between alternatives.This period is particularly deserving of study, Hoffmann argues, because it was then that the existence of free will first began to be "investigated within a philosophical account of action," rather than merely asserted on theological grounds as a necessary corollary of the doctrines of grace and sin (1). Consequently, theological anthropology took what Hoffmann calls a "psychological turn," with theologians newly determined to explain rational agency in terms of the interaction between different powers of the soul. In Hoffmann's estimation, the subsequent debates over the respective roles of intellect and will in the process of decision-making, as well as the relation between faulty cognition and voluntary wrongdoing, gave rise to some of the most innovative theories of free will in the later Middle Ages—including not only those of celebrated thinkers such as Thomas Aquinas and John Duns Scotus, but also those of lesser-known luminaries such as [End Page 388] John of Pouilly and Peter Auriol. Although the concerns that motivated these debates were primarily anthropological, having to do with specifically human psychological processes, Hoffmann's study foregrounds the role that the angels played in the unfolding of various controversies. Comparing medieval angelological discussion to the thought experiments commonly employed by contemporary philosophers, Hoffmann argues that angels proved significant because they provided a subject matter in which rational freedom could be considered in a pure and ideal form, abstracted from any material constraints (3). While the angelic nature was certainly regarded as worthy of study in its own right, it was also often viewed as an opportunity to explore the nature of cognition and volition simpliciter, in relation to which the distinctiveness of human psychology could be better understood.The book is divided into three parts, each of which traces the historical development of a distinct topic related to the free will debate. In the first part, Hoffmann presents a lucid account of the various ways that medieval thinkers employed Aristotelian ideas—including not only the essentials of his action theory, but also metaphysical doctrines such as the distinction between active and passive powers—as they sought to explain the psychological origins of free will. Comprising over half the text, these chapters provide a comprehensive overview of the free will debate from its origins in the writings of Anselm of Canterbury to its culmination in the proto-modern theorizing of William of Ockham, including a thorough discussion of the controversies...

This article examines Abu Nasr al-Farabı (c. 872–950/1) on the topic of intentionality, with particular focus on how intentionality is integral for the constitution of the intellect within his psychology. Unfortunately, targeted study of al-Farabı’s doctrine of intentionality has been largely neglected since Kwame Gyekye’s 1971 essay, The Terms ‘Prima Intentio’ and ‘Secunda Intentio’ in Arabic Logic. Gyekye showed that the Arabic (and thus the Latin) doctrine of first and second intention originated within the texts of al-Farabı,not the texts of (...) Avicenna, as had been previously thought. In response, this article aims to show three things. First, while the doctrine of first and second intention appears in al-Farabı’s texts, it is not as clearly developed or defined as is presented in Gyekye’s 1971 article. al-Farabı both lacks consistent technical terminology for the doctrine (as he discusses it across disparate sciences, in unrelated contexts) and develops it far too little to fully flesh out his doctrine. Second, even given the fact that al-Farabı’s discussion of intentionality is underdeveloped, Gyekye was right to credit the doctrine to him. And third, al-Farabı’s doctrine of first and second intention is not merely important to understand his positions regarding signification and universals; they play a pivotal role in the constitution of the human intellect.

Humans can think about their conscious experiences using a special class of ?phenomenal? concepts. Psychophysical identity statements formulated using phenomenal concepts appear to be contingent. Kripke argued that this intuited contingency could not be explained away, in contrast to ordinary theoretical identities where it can. If the contingency is real, property dualism follows. Physicalists have attempted to answer this challenge by pointing to special features of phenomenal concepts that explain the intuition of contingency. However no physicalist account of their distinguishing (...) features has proven to be satisfactory. Leading accounts rely on there being a phenomenological difference between tokening a physical-functional concept and tokening a phenomenal concept. This paper shows that existing psychological data undermine that claim. The paper goes on to suggest that the recalcitrance of the intuition of contingency may instead by explained by the limited means people typically have for applying their phenomenal concepts. Ways of testing that suggestion empirically are proposed. (shrink)

BBS Commentary on: Susan Carey: The Origin of Concepts. -/- Carey’s book describes many cases where children develop new concepts with expressive power that could not be constructed out of their input.

My goal in this paper is to account for the value of species in terms of the value of individual organisms that make them up. Many authors have pointed to an apparent conflict between a species preservationist ethic and moral theories that place value on individuals. I argue for an account of the worth of individual organisms grounded in the representational goals of those organisms. I claim thatthis account leads to an acceptably extensive species preservationist ethic.
