The history of the research on peptic ulcer disease is characterized by a premature abandonment of the bacterial hypothesis, which subsequently had its comeback, leading to the discovery of Helicobacter pylori – the major cause of the disease. In this paper we examine the received view on this case, according to which the primary reason for the abandonment of the bacterial hypothesis in the mid-twentieth century was a large-scale study by a prominent gastroenterologist Palmer, which suggested no bacteria could be (...) found in the human stomach. To this end, we employ the methodof digital textual analysis and study the literature on the etiology of PUD published in the decade prior to Palmer’s article. Our findings suggest that the bacterial hypothesis had already been abandoned before the publication of Palmer’s paper, which challenges the widely held view that his study played a crucial role in the development of this episode. In view of this result, we argue that the PUD case does not illustrate harmful effects of a high degree of information flow, as it has frequently been claimed in the literature on network epistemology. Moreover, we argue that alternative examples of harmful effects of a high degree of information flow may be hard to find in the history of science. (shrink)

In this article I develop a big picture of the evolution of human cooperation, and contrast it to an alternative based on group selection. The crucial claim is that hominin history has seen two major transitions in cooperation, and hence poses two deep puzzles about the origins and stability of cooperation. The first is the transition from great ape social lives to the lives of Pleistocene cooperative foragers; the second is the stability of the social contract through the early Holocene (...) transition to complex hierarchical societies. The first of these transitions is driven, at least initially, by individual advantage: cooperation paid off for individual foragers, initially through mutualist interaction, then through reciprocation. This argument leads to a reanalysis of the role of violence and the nature of the freeriding threat to cooperation. But the conditions that select for cooperative individuals in the Pleistocene were eroded in the Pleistocene–Holocene transition. So we need an alternative account of the survival, and indeed the expansion, of cooperation in the Holocene. Group selection driven by intercommunal conflict really may well be central to this second transition. (shrink)

A common picture of evolution by natural selection sees it as a process through which organisms change so that they become better adapted to their environment. However, agents do not merely respond to the challenges their environments pose. They modify their environments, filtering and transforming the action of the environment on their bodies A beaver, in making a dam, engineers a stream, increasing both the size of its safe refuge and reducing its seasonal variability. Beavers, like many other animals, are (...) ecological engineers. They act to modify the physical challenges posed by their environment. Nests, burrows and other shelters reduce the impacts of adverse weather and of other agents. Animal also modify their exposure to biological risks. Hygienic behaviour reduces the impact of disease.

This paper discusses in broad terms the metaphysical projects of Sydney Shoemaker’s Physical Realization . Specifically, I examine the effectiveness of Shoemaker’s novel “subset” account of realization for defusing the problem of mental causation, and compare the “subset” account with the standard “second-order” account. Finally, I discuss the physicalist status of the metaphysical worldview presented in Shoemaker’s important new contribution to philosophy of mind and metaphysics.

Within paleoanthropology, the origin of behavioral modernity is a famous problem. Very large-brained hominins have lived for around half a million years, yet social lives resembling those known from the ethnographic record appeared perhaps 100,000 years ago. Why did it take 400,000 years for humans to start acting like humans? In this article, I argue that part of the solution is a transition in the economic foundations of cooperation from a relatively undemanding form, to one that imposed much more stress (...) on human motivational and cognitive mechanisms. The rich normative, ceremonial, and ideological lives of humans are a response to this economic revolution in forager lives; from one depending on immediate return mutualism to one depending on delayed and third-party reciprocation.

Given the widening gap between the number of individuals on transplant waiting lists and the availability of donated organs, as well as the recent plateau in donations based on neurological criteria, there has been a growing interest in expanding donation after circulatory determination of death. While the prevalence of this form of organ donation continues to increase, many thorny ethical issues remain, often creating moral distress in both clinicians and families. In this article, we address one of these issues, namely, (...) the challenges surrounding patient and surrogate informed consent for donation after circulatory determination of death. First we discuss several general concerns regarding consent related to this form of organ donation, and then we address additional issues that are unique to three different patient categories: adult patients with medical decision-making capacity or potential capacity, adult patients who lack capacity, and pediatric patients.

The standard view of the function of reason is that it emerged to enable individuals to make better judgements and choices. Once individuals could think better, and once we had suitable communicative tools, individual reasoning acquired a public face; we reasoned together as well as privately, in our own mind. Hugo Mercier and Dan Sperber argue that this gets the story the wrong way around: reasoning evolved for public purposes: to persuade, negotiate, assess. Once it was established publically, perhaps it (...) acquired a private function too. With the exception of a few minor complaints, this evolutionary case is well made. However, Mercier and Sperber embed their evolutionary case within a modular view of the mind and suggest a modular view of public reasoning itself. While I find the evolutionary case persuasive, I am sceptical of the cognitive science framework. (shrink)

Until relatively recently, it was often supposed that changes in the material record of hominin life indexed advances in hominin cognitive sophistication in a relatively direct way. In particular, the “Upper Paleolithic Transition”—an apparently abrupt increase in the complexity and disparity of our material culture—was thought to signal the arrival of the fully human mind. While the idea of a direct relationship between material complexity and cognitive sophistication still has some defenders, this view has largely been abandoned. It is now (...) widely appreciated that aspects of ancient hominins’ demographic and social organization have a powerful influence both on the material culture they need and the material culture they can sustain. But if this more nuanced view is right, what does the deep material record tell us about the evolution of hominin cognition? I explore that question in this article. (shrink)

This anthology, intended to accompany _A Companion to Metaphysics_, brings together over 60 selections which represent the best and most important works in metaphysics during this century. The selections are grouped under ten major metaphysical problems and each section is preceded by an introduction by the editors.

While it is well known that Zhuangzi uses metaphor extensively, there is much less appreciation of the role that it plays in his thought-a topic that is investigated in this essay. At the same time, this investigation is closely concerned with questions about the nature of metaphor. Comparisons are made between a central metaphorical structure in the Zhuangzi on the one hand and contemporary views of the nature of metaphor by Donald Davidson and by Lakoff and Johnson on the other. (...) It is hoped that these comparisons will help to illuminate the central metaphorical structure and its role in the philosophy of the Zhuangzi. (shrink)

There is a very striking difference between even the simplest ethnographically known human societies and those of the chimps and bonobos. Chimp and bonobo societies are closed societies: with the exception of adolescent females who disperse from their natal group and join a nearby group (never to return to their group of origin), a pan residential group is the whole social world of the agents who make it up. That is not true of forager bands, which have fluid memberships, and (...) regular associations with neighbouring bands. They are components of a larger social world. The open and fluid character of forager bands brings with it many advantages, so the stability of this more vertically complex form of social life is not difficult to explain, once it establishes. But how did it establish, if, as is likely, earlier hominin social worlds resemble those of our close pan relatives in the suspicion (even hostility) of one band to another? How did hominin social organisation transition from life in closed bands, each distrustful of its neighbours, to the much more open social lives of foragers? I will discuss and synthesise two approaches to this problem, one ecological, based on the work of Robert Layton and his colleagues, and another that is organised around an expansion of kin recognition, an idea primarily driven by Bernard Chapais. The paper closes by discussing potential archaeological signatures both of more open social worlds, and of the supposed causal drivers of such worlds. (shrink)

A preference method probed infants` perception of object motion on an inclined plane. Infants viewed videotaped events in which a ball rolled downward (or upward) while speeding up (or slowing down). Then infants were tested with events in which the ball moved in the opposite direction with appropriate or inappropriate acceleration. Infants aged 7 months, but not 5 months, looked longer at the test event with inappropriate acceleration, suggesting emerging sensitivity to gravity. A further study tested whether infants appreciate that (...) a stationary object released on an incline moves downward rather than upward; findings again were positive at 7 months and negative at 5 months. A final study provided evidence, nevertheless, that 5-monthold infants discriminate downward from upward motion and relate downward motion in videotaped events to downward motion in live events. Sensitivity to certain effects of gravity appears to develop in infancy. (shrink)

Is 'development' a concept that properly belongs to mind and morality and, if it does, what account can we give of moral development now that Piagetian and Kohlbergian models are increasingly being abandoned in developmental psychology? In addressing this central issue, it is hoped that the paper will contribute to the quest for a new integrated model of moral functioning, called for in the September 2008 Special Issue of the Journal of Moral Education (37[3]). Our paper argues that the notion (...) of moral development is fully justified, though it does not occur via invariant stages. Rather, each child is an emergent self-organising organism in which development is highly variable, dynamic and often non-linear. By viewing each child as a self-organising being and adopting the notion that moral development is dynamic and emergent from the predilection to value, the paper points towards a new account of moral development that opens up new avenues for educational research and moral education in schools.

Disability, like questions of race, gender, and class, is one of the most provocative topics among theorists and philosophers today. This volume, situated at the intersection of feminist theory and disability studies, addresses questions about the nature of embodiment, the meaning of disability, the impact of public policy on those who have been labeled disabled, and how we define the norms of mental and physical ability. The essays here bridge the gap between theory and activism by illuminating structures of power (...) and showing how historical and cultural perceptions of the human body have been informed by and contributed to the oppression of women and disabled people.

Somites are transient structures which represent the most overt segmental feature of the vertebrate embryo. The strict temporal regulation of somitogenesis is of critical developmental importance since many segmental structures adopt a periodicity based on that of the somites. Until recently, the mechanisms underlying the periodicity of somitogenesis were largely unknown. Based on the oscillations of c-hairy1 and lunatic fringe RNA, we now have evidence for an intrinsic segmentation clock in presomitic cells. Translation of this temporal periodicity into a spatial (...) periodicity, through somite formation, requires Notch signaling. While the Hox genes are certainly involved, it remains unknown how the metameric vertebrate axis becomes regionalized along the antero–posterior (AP) dimension into the occipital, cervical, thoracic, lumbar, and sacral domains. We discuss the implications of cell division as a clock mechanism underlying the regionalization of somites and their derivatives along the AP axis. Possible links between the segmentation clock and axial regionalization are also discussed. (shrink)

Perceptual expertise refers to learning that is specific to a domain, that transfers to new items within the trained domain, and that leads to automatic processing in the sense that expertise effects can be measured across a variety of tasks. It can be argued that most of us possess some degree of perceptual expertise in a least one, if not several domains, thereby giving the study of perceptual expertise broad application. Some object categories may in fact be objects of perceptual (...) expertise to the majority of people: Faces appear to be one such example. Thus, the use of face stimuli, or the comparison of face and object perception, can be a powerful way to ask whether a given process is influenced by perceptual expertise. Here, we emphasize one characteristic way that face processing appears to differ from nonface processing: that is, the degree to which they recruit a “holistic” rather than a “featural” perceptual strategy. This review brings evidence that expertise influences perceptual processing together with recent findings that the capacity of visual short-term memory is greater in perceptual experts and explores the relationship between the two.

According to surveys of companies, branding is one of the main objectives of their corporate social responsibility. With advantageous data from Brand Finance, we address three contextual factors that may condition the relationship between CSR and brand value. First, we hypothesize that the relationship between CSR and brand value obtains across major world regions and industrial sectors. Second, we hypothesize that the relationship has weakened with time, as companies have had increasing difficulty using CSR to differentiate their brands in a (...) sea of CSR-espousing competitors. Third, we hypothesize that the relationship between CSR and brand value is weaker where a brand’s identity is different from that of its corporate owner, which may make it difficult for observers to readily link CSR with its potential brand beneficiaries. We support these hypotheses with random-effects, fixed-effects, and instrumental-variable regressions before ending with contributions, limitations, implications, and potential next steps. (shrink)

This paper offers a critique of the emphasis on anti-futurity and failure prevalent in contemporary queer theory. I argue that responsibility for climate change requires commitments to futures that are queer, crip, and feminist. A queer crip feminist commitment to the future is, I contend, informed by radical hope.

This paper is an exposition and defense of Kant’s philosophy of geometry. The main thesis is that Euclidean geometry investigates the properties of geometrical objects in an inner space that is given to us a priori (pure space) and hence is a priori and synthetic. This thesis is supported by arguing that Euclidean geometry requires certain intuitive objects (Sect. 1), that these objects are a priori constructions in pure space (Sect. 2), and finally that the role of geometrical construction is (...) to provide geometrical objects, not concepts, as some have claimed (Sect. 3).

In the Confucian tradition, the ideal government is called "benevolent government" (ren zheng), central to which is the ruler's parental love toward his people who he deems as his children. Hanfeizi criticized this seemingly innocent political idea by pointing out that (1) not only is the state not a family but even within the family parental love is short of making the children orderly and (2) ren as love inevitably results in the ruin of the state because it confuses what (...) is right/meritorious with what is not, thus disrupts the legal system. In this paper, I defend Confucian virtue politics against Hanfeizi's criticisms. I argue that by failing to grasp the complex nature of ren that encompasses both emotion (ren as love) and moral virtue (ren as filiality), Hanfeizi also failed to understand the actual process in which the ruler's parental love is extended to the people.

It is commonplace by now that moral philosophy has a long history of gender biases, not only regarding the pertinent moral issues but also regarding the development of concepts and theories. This insight from feminist philosophy, however, has not yet received sufficient attention in the debate on supererogation. That is not least surprising, since we all are familiar with the phenomenon that what is morally expected of an agent is not gender-neutral but at least to some extent relates to gender (...) roles and social expectations. Therefore, the main aim of this chapter is to build on theoretical and methodological insights from feminist philosophy to carve out this research gap and to map the field for future research. It will be argued that feminist approaches can only be ignored within the debate on supererogation at the cost of philosophical rigor since they do not only give rise to novel perspectives and insights on questions already discussed, but also make matters visible that would have been overlooked otherwise. Thereby this chapter seeks essentially to contribute to a more extensive understanding of the social, political, and epistemic dimensions of supererogation that have hitherto been neglected.

Some commentators hold that Xunzi's criticism of Mencius' thesis that human nature is good depends more on Xunzi's definition of xing or nature than on substantive argument. Some also claim that Xunzi is committed to accepting Mencius' thesis. A more precise account of Xunzi's critique is offered here, based on an elaboration of his distinction in the "Xing e pian" between ke yi (capacity) and neng (ability). Others have noted this distinction, but no one has sufficiently appreciated its role in (...) making Xunzi's critique more systematic and substantive than it is usually thought to be. (shrink)

Under Mencius' influence jen has been regarded as part of a theory of nature. As such, commentators have had difficulty resolving the apparent paradox in "Analects" 9.1 that Confucius rarely talked about jen. No paradox arises if jen is seen as a practice involving self-cultivation as a never-ending task and the immediacy of ethical commitment where a cluster of emotions, attitudes, and values are expressed. Jen is an ethical orientation from which one speaks and acts--not particular qualities that one might (...) enumerate and claim to possess. As such, the internal relation between jen and li does not amount to their being the same thing, as implied by some recent writers. (shrink)

In this paper, I will argue that Radfords real question is not the conceptual one, as it is usually taken, but the causal one, and show that Waltons account, which treats Radfords puzzle as the conceptual question, is not a satisfactory solution to it. I will also argue that contrary to what Walton claims, the causal question is not only important, but also closely related to the conceptual and normative questions. What matters is not that Walton has not solved Radfords (...) puzzle per se, but that he has not recognized the importance of this puzzle. While doing this, I will suggest a revision to the cognitive theory of emotion. (shrink)

Nursing programs are complex systems that articulate values of relationality and holism, while developing curriculums that privilege metric‐driven competency‐based pedagogies. This study used an interpretive approach to analyze interviews from 20 nursing students at two Canadian Baccalaureate programs to understand how nursing's educational context, including its hidden curriculums, impacted student writing activities. We viewed this qualitative data through the lens of activity theory. Students spoke about navigating a rigid writing context. This resulted in a hyper‐focus on “figuring out” the teacher (...) with minimal focus on the act of writing. Students used a form of behavioral “code‐switching” to maximize their grade while considering how their “valuing” of the assignment fit within their writing motives. Hidden curriculum messages taught students that academic success was assured whether their writing mirrored instructor preferences. Instructional practices of rigidity reinforced unequal social conditions for some minority students. Faculty can counteract the impact of the hidden curriculum through encouragement of choice and independent thinking about writing activities. Acknowledging power relationships and their influence on how students navigate writing assignments and nursing discourse may relieve pressures on students who fear penalties for countering norms and result in a more flexible learning environment.

Many employees with strong religious convictions find themselves living in two separate worlds: the sacred private world of family and church where they can express their faith freely and the secular public world where religious expression is strongly discouraged. We examine the origins of sacred/secular divide, and show how this division is an outcome of modernism replacing Christianity as the dominant worldview in western society. Next, we make the case that guiding assumptions (or faith) is inherent in every worldview, system (...) of thought, or religion and also show that scientific reason can never be a comprehensive or totalizing meaning system, particularly in the realm of ethics. The underlying assumptions of the sacred/secular divide are seriously questioned which has implications for employees who desire to integrate faith and career. Finally, we offer possibilities for individuals and corporate entities to integrate the personal and sacred with the institutional and secular. (shrink)

Sehen, Horen, Riechen, Schmecken, Tasten: Die Autorin fragt nach Entstehung, Begrundung und Folgen dieser tradierten Ordnung der Sinne.

Es ist ein verbreitetes Phänomen unserer moralischen Urteilspraxis, dass wir herausragende moralische Handlungen bisweilen als moralisch wertvoll und dennoch nicht als moralisch geboten beurteilen, d.i. als supererogatorisch. Für die kantische Ethik stellt diese Beobachtung eine Herausforderung dar. Nicht nur verfügt sie nicht über eine Kategorie der Supererogation, vielmehr scheinen die wenigen Stellen, an denen sich Kant explizit mit moralisch herausragendem Handeln befasst, auf den ersten Blick dafür zu sprechen, dass eine solche Urteilspraxis schlicht als fehlerhaft zurückzuweisen ist. Dagegen arbeitet die (...) Studie heraus, dass die kantische Ethik einen theoretischen Rahmen für eine nuancierte moralpsychologische Analyse dieser Praxis bietet: Moralisch herausragende Handlungen als supererogatorisch zu betrachten erweist sich demnach einerseits als vielschichtige Gefährdung der eigenen Moralität, andererseits vermag das gute Exempel anderer unter bestimmten Bedingungen durchaus zur Beförderung der eigenen Moralität beizutragen. Die Studie trägt zu einem differenzierteren Verständnis der kantischen Ethik bei und weist eine genuin kantische Perspektive auf Supererogation als systematisch anschlussfähig an aktuelle Debatten aus.
