Through the analysis of practices of a primary school teacher-in-training during her practicum, the author aims to better understand professional and personal experience. A concrete case issued from a clinical, longitudinal and comparative study led between 2008 and 2009 in comparison with two teachers-in-training reports the interiorization process and the capitalized experience. The comparative study is issued of an innovative practicum project in operation during three years from 2007 to 2009 in the University of Montpellier, and called ‘moderated writing workshop’. (...) The exploratory study leans on notions like experience and professional culture suited to the classroom. The methodology is that of a clinical analysis of one case, followed by the analysis of the verbal and behavioral elements included in the interviews in order to set stabilized long-running categories. The skills and knowledge undertaken by the teacher-in-training examining her own practice are carefully analyzed all along, thus creating an innovative system. The results show that an important evolution occurs concerning practical rules, which seems relevant for the professionals. Those rules give to formative people information about professionalism. Results are discussed before concluding. (shrink)

White, Christensen, and Feldman have recently endorsed uniqueness, the thesis that given the same total evidence, two rational subjects cannot hold different views. Kelly, Schoenfield, and Meacham argue that White and others have at best only supported the weaker, merely intrapersonal view that, given the total evidence, there are no two views which a single rational agent could take. Here, we give a new argument for uniqueness, an argument with deliberate focus on the interpersonal element of the thesis. Our argument (...) is that the best explanation of the value of promoting rationality is an explanation that entails uniqueness. (shrink)

Do sensory measurements deserve the label of “measurement”? We argue that they do. They fit with an epistemological view of measurement held in current philosophy of science, and they face the same kinds of epistemological challenges as physical measurements do: the problem of coordination and the problem of standardization. These problems are addressed through the process of “epistemic iteration,” for all measurements. We also argue for distinguishing the problem of standardization from the problem of coordination. To exemplify our claims, we (...) draw on olfactory performance tests, especially studies linking olfactory decline to neurodegenerative disorders. (shrink)

Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction. This gradual weakening and shifting of stimulus-responsive cells has critical implications for sensory stimulus–response models and perceptual decision-making. While representational drift may complicate traditional sensory processing models, it could be seen as an advantage in olfaction, as animals live in environments with constantly (...) changing and unpredictable chemical information. Non-topographical encoding in the olfactory system may aid in contextualizing reactions to promiscuous odor stimuli, facilitating adaptive animal behavior and survival. This article suggests that traditional models of stimulus–(neural) response mapping in olfaction may need to be reevaluated and instead motivates the use of dynamical systems theory as a methodology and conceptual framework.

In everyday life, we usually go by theone-body-one-person rule: one person has one body. This social belief builds on two assumptions: bodies are individual units and they are the same in different situations. This is also the conceptual resource for social theories that build on the notion of individuals. In this article, we turn it into a sociological topic. We develop a vocabulary for reconstructing bodily one-ness and bodily sameness as practically achieved social order, asbody boundary work: what belongs to (...) a body is a matter of local practices that define its situational contours, limits and margins. Practices of identification and personification draw on social memories and enact bodies as trans-situational entities. Persons and bodies, we argue, evolve in co-individuation. Personal corporality, then, can be conceptualized as abody of workthat encompasses these practical efforts of boundary-making. (shrink)

This volume explores the relationship between physics and metaphysics in Descartes' philosophy. According to the standard account, Descartes modified the objects of metaphysics and physics and inverted the order in which these two disciplines were traditionally studied. This book challenges the standard account in which Descartes prioritizes metaphysics over physics. It does so by taking into consideration the historical reception of Descartes and the ways in which Descartes himself reacted to these receptions in his own lifetime. The book stresses the (...) diversity of these receptions by taking into account not only Cartesianisms but also anti-Cartesianisms, and by showing how they retroactively highlighted different aspects of Descartes' works and theoretical choices. The historical aspect of the volume is unique in that it not only analyzes different constructions of Descartes that emerged in the 18th, 19th and 20th centuries, but also reflects on how his work was first read by philosophers across Europe. Taken together, the essays in this volume offer a fresh and up-to-date contribution to this important debate in early modern philosophy. (shrink)

It is widely known that dreams can be strongly affected by traumatic events, but there may be other ways in which dreams relate to trauma. In this paper, we argue that different types of dreams could both contribute to trauma and alleviate it according to the prediction errors that occur either in dreams or in response to them after waking. A prediction error occurs when an experience contradicts one’s expectation and it is often accompanied by surprise. Prediction errors are involved (...) in memory updating processes that can be long-lasting. Not only nightmares but also unpleasant, and surprisingly, even neutral and pleasant dreams have the potential to contribute to trauma, affecting our waking lives in a similar way to waking traumatic experiences. We postulate that certain dreams can also be beneficial for trauma alleviation. Further, clinical evidence suggests that working with prediction errors that occurred in dreams and during our response to dreams after waking can assist in alleviating the negative effects of trauma.

While cancer survivors commonly experience fear and anxiety, a substantial minority experience an enduring and debilitating fear that their cancer will return; a condition commonly referred to as fear of cancer recurrence. Despite recent advances in this area, little is known about FCR among people from Indigenous or other ethnic and racial minority populations. Given the high prevalence and poor outcomes of cancer among people from these populations, a robust understanding of FCR among people from these groups is critical. The (...) current review identified and aggregated existing literature on FCR amongst adult cancer survivors from Indigenous and minority populations. The protocol of this review was registered with PROSPERO in July 2020. A systematic search of bibliographic databases was conducted for relevant articles published from 1997 to November 2019. Data from eligible articles were extracted and appraised for quality by two independent reviewers. Nineteen articles from four countries met the inclusion criteria, including 14 quantitative, 4 qualitative and 1 mixed-methods study. Only one article reported on an Indigenous population. Few studies reported on FCR prevalence or severity. While the variation in tools used to measure FCR hindered a robust estimate of severity, results suggested some differences in FCR severity between minority and dominant populations, although these may have been due to study metholodological differences. Few factors were reported as being associated with FCR in minorities across multiple studies. The qualitative synthesis found five themes associated with the lived experience of FCR: variations in the lived experience of FCR; spirituality and worldview impacting on FCR; the importance of staying positive; complexities around support; and increasing cancer knowledge. The findings of this review highlight differences in FCR across cultures and contexts, which reinforces the need for culturally-specific approaches to this condition. The dearth of research in this area is of concern given the significant burden of cancer in these populations. A deeper understanding of this condition among Indigenous and minority populations is critical to developing and delivering appropriate and effective psychosocial care for cancer survivors from these groups.

In many judicial systems, confessions are a requirement for criminal conviction. Even if confessions are intrinsically convincing, this might not entirely explain why they play such a paramount role. In addition, it has been suggested that confessions owe their importance to their legitimizing role, explaining why they could be required even when other evidence has convinced a judge. But why would confessions be particularly suited to justify verdicts? One possibility is that they can be more easily transmitted from one individual (...) to the next, and thus spread in the population without losing their convincingness. 360 English-speaking participants were asked to evaluate the convincingness of one of three justifications for a verdict, grounded either in a confession, eyewitnesses, or circumstantial evidence, and to pass on that justification to another participant, who performed the same task. Then, 240 English-speaking participants evaluated the convincingness of some of the justifications produced by the first group of participants. Compared to the other justifications, justifications based on confessions lost less of their convincingness in the transmission process. Modeling pointed to the most common forms the justifications would take as they are transmitted, and results showed that the most common variant of the justification based on a confession was more convincing.

In times of crisis and social turbulence, the mass media play a crucial role. This becomes particularly evident in economic crises within the European Union. The (biased) way the crisis is reported shapes people’s understanding of the crisis and the parties involved. In this study, the coverage of the Greek sovereign debt crisis in the German newspapers BILD, Die Welt, Frankfurter Allgemeine Zeitung, Süddeutsche Zeitung, tageszeitung and Der Spiegel (online) is examined for the quality criteria relevance, neutrality, balance, and analytical (...) quality. The results show that the reporting is appropriate to the relevance of the topic, but shows deficits in the criteria of balance, neutrality, and analytical quality. During the study period, coverage focuses on a small number of topics, journalists include their value judgments in news and reports. Overall, there is an obvious media bias against the Greek government’s position. (shrink)

This paper questions the taken-for-granted moral portrayal depicted in the extant literature and popular media of the devoted social entrepreneurial hero with a priori good ethical and moral credentials. We confront this somewhat ‘idealistic’ and biased portrayal with insights from unique large-scale data from the Global Entrepreneurship Monitor 2009 survey on social entrepreneurship covering Belgium and The Netherlands. Binary and multinomial logistic regressions indicate that the intention and dominance of perceived social value creation over economic value creation is indeed what (...) makes social entrepreneurs unique. In contrast to the extant literature, however, our empirical investigation points at a reluctant attitude of social entrepreneurs toward entrepreneurship in terms of confidence in their skills to start and manage a business, their perception of entrepreneurship as a desirable career choice and their involvement in their activities. While the extant literature points at a strong entrepreneurial orientation as a source of ethical issues, the main contribution of this study lies in the reverse observation: ethical issues are also likely to emanate from a frail entrepreneurial profile. We formulate empirically grounded propositions that may serve as a basis for theory-building and testing purposes. (shrink)

There are many conflicting attitudes to technological progress: some people are fearful that robots will soon take over, even perhaps making ethical decisions for us, whilst others enthusiastically embrace a future largely run for us by them. Still others insist that we cannot predict the long term outcome of present technological developments.

Credences, unlike full beliefs, can’t be true or false. So what makes credences more or less accurate? This chapter offers a new answer to this question: credences are accurate insofar as they license true educated guesses, and less accurate insofar as they license false educated guesses. This account is compatible with immodesty; : a rational agent will regard her own credences to be best for the purposes of making true educated guesses. The guessing account can also be used to justify (...) certain coherence constraints on rational credence, such as probabilism. The chapter concludes by discussing some advantages of the guessing account over rival accounts of accuracy. (shrink)

The philosophical difficulties presented by self-deception are vexed and multifaceted. One such difficulty is what I call the ‘doxastic problem’ of self-deception. Solving the doxastic problem involves determining whether someone in a state of self-deception that ∼p both believes that p and believes that ∼p, simply holds one or the other belief, or, as I will argue, holds neither. This final option, which has been almost entirely overlooked to-date, is what I call ‘ nondoxasticism ’ about self-deception. In this article, (...) I present a negative case for nondoxasticism according to which, in the paradigm case of self-deception, there is no explanatory need to attribute the self-deceived person either their undesired belief that p, or their desired belief that ∼p. Folk psychology is replete with concepts other than belief, and if we bear this in mind, it becomes clear that the explanatory roles for which the self-deceived person's purported beliefs have traditionally been enlisted can be comfortably filled without recourse to belief.

Sophie Grace Chappell develops a picture of what philosophical ethics can be like, once set aside from the idealising and reductive pressures of conventional moral theory. Her question is 'How are we to know what to do?', and the answer she defends is 'By developing our moral imaginations'.

The discovery of RNA interference in 1998 has made a lasting impact on biological research. Identifying the regulatory role of small RNAs changed the modes of molecular biological inquiry as well as biologists' understanding of genetic regulation. This article examines the early years of small RNA biology's success story. I query which factors had to come together so that small RNA research came into life in the blink of an eye. I primarily look at scientific repertoires as facilitators of rapid (...) scientific change. I show that for a short period of time, between the years 1998 and 2002, different model organism communities, investigative strategies, technological innovations, and research interests could be successfully aligned to take small RNA research off the ground. I discuss how the keystone discoveries were situated in specific experimental traditions and what strategies were employed to establish these discoveries as more general phenomena. Providing thus a practice-based approach of rapid scientific change, I ask how to relate the change in propositional bits of scientific knowledge with changes in scientific practice. (shrink)

Closure is the central premise in one of the best arguments for physicalism—the argument from causal overdetermination. According to Closure, at every time at which a physical event has a sufficient cause, it has a sufficient physical cause. This principle is standardly defended by appealing to the fact that it enjoys empirical support from numerous confirming cases (and no disconfirming cases) in physics. However, in recent literature on mental causation, attempts have been made to provide a stronger argument for it. (...) This essay argues that, insofar as these attempts are successful, they actually establish a far stronger closure principle. Worryingly, the acceptance of this stronger principle presents a new problem for the most popular form of physicalism, that of nonreductive physicalism. The problem shall be referred to as the 'Problem of Strong Closure.'. (shrink)

Objective To explore attitudes towards conscientious objections among medical students in the UK. Methods Medical students at St George's University of London, Cardiff University, King's College London and Leeds University were emailed a link to an anonymous online questionnaire, hosted by an online survey company. The questionnaire contained nine questions. A total of 733 medical students responded. Results Nearly half of the students in this survey stated that they believed in the right of doctors to conscientiously object to any procedure. (...) Demand for the right to conscientiously object is greater in Muslim medical students when compared with other groups of religious medical students. Discussion Abortion continues to be a contentious issue among medical students and this may contribute to the looming crisis in abortion services over the coming years. This project sheds some light on how future doctors view some of their ethical rights and obligations. Using empirical evidence, it reveals that conscientious objection is an issue in the UK medical student body today. These data could help anticipate problems that may arise when these medical students qualify and practise medicine in the community. Conclusion Clearer guidance is needed for medical students about the issue of conscientious objection at medical school. (shrink)

Philosophical discussion on control has largely centred around control over our actions and beliefs. Yet this overlooks the question of whether we also have control over the reasons for which we act and believe. To date, the overriding assumption appears to be that we do not, and with seemingly good reason. We cannot choose to act for a reason and acting-for-a-reason is not itself something we do. While some have challenged this in the case of reasons for action, these claims (...) seem especially untenable regarding believing for a reason. And extending the scope of control in this way also faces the threat of regress. In the face of this orthodoxy, the present paper argues that we do in fact have control over both believing and acting for a particular reason. It also starts to develop an account of the way in which this would be possible. Given the broad importance of understanding control and agency, this paper bears on a number of topics in epistemology, the philosophy of mind, and ethics. (shrink)

In his insightful review, Eugene V. Koonin discusses various aspects of CRISPR-Cas systems with a strong focus on their qualities as "adaptive immune systems". The CRISPR-Cas system is most famous for its application as a gene-editing tool. Koonin provides a deeper insight into its biological function in bacteria, which is to immunize the cell against parasite DNA. I shall comment on one issue discussed in the text, in two steps. First, I shall elaborate on CRISPR-Cas systems and their supposed Lamarckian (...) character. Criteria for calling biological phenomena genuinely Lamarckian will be narrowed down and then applied to the CRISPR-Cas system, considering interference-driven spacer acquisition as an instantiation of a truly Lamarckian paradigm. Second, I shall consider whether Lamarckian and "canonical" instances of inheritance are a case of theoretical pluralism, being two non-reducible, yet interconnected paradigms. (shrink)

Emergence is often described as the idea that the whole is greater than the sum of the parts: interactions among the components of a system lead to distinctive novel properties. It has been invoked to describe the flocking of birds, the phases of matter and human consciousness, along with many other phenomena. Since the nineteenth century, the notion of emergence has been widely applied in philosophy, particularly in contemporary philosophy of mind, philosophy of science and metaphysics. It has more recently (...) become central to scientists' understanding of phenomena across physics, chemistry, complexity and systems theory, biology and the social sciences. The Routledge Handbook of Emergence is an outstanding reference source and exploration of the concept of emergence, and is the first collection of its kind. Thirty-two chapters by an international team of contributors are organised into four parts: Foundations of emergence Emergence and mind Emergence and physics Emergence and the special sciences Within these sections important topics and problems in emergence are explained, including the British Emergentists; weak vs. strong emergence; emergence and downward causation; dependence, complexity and mechanisms; mental causation, consciousness and dualism; quantum mechanics, soft matter and chemistry; and evolution, cognitive science and social sciences. Essential reading for students and researchers in philosophy of mind, philosophy of science and metaphysics, The Routledge Handbook of Emergence will also be of interest to those studying foundational issues in biology, chemistry, physics and psychology.

This paper offers a critique of ‘powerful knowledge’ – a concept in Education Studies that has been presented as a just basis for school curricula. Powerful knowledge is disciplinary knowledge produced and refined through a process of ‘specialisation’ that usually occurs in universities. Drawing on postcolonial, decolonial and Indigenous studies, we show how powerful knowledge seems to focus on the progressive impulse of modernity while overlooking the ruination of colonial racism. We call on scholars and practitioners working with the powerful (...) knowledge framework to address more fully the hegemonic relations of disciplinary specialisation and its historical connections to colonial-modernity. This, we argue, would enable curriculum knowledge that is ‘powerful’ in its interrogation of racial violence, rather than in its epistemic reproduction of it. (shrink)

This book develops a unique phenomenology of plurality by introducing Hannah Arendt’s work into current debates taking place in the phenomenological tradition. Loidolt offers a systematic treatment of plurality that unites the fields of phenomenology, political theory, social ontology, and Arendt studies to offer new perspectives on key concepts such as intersubjectivity, selfhood, personhood, sociality, community, and conceptions of the "we." _Phenomenology of Plurality_ is an in-depth, phenomenological analysis of Arendt that represents a viable third way between the "modernist" and (...) "postmodernist" camps in Arendt scholarship. It also introduces a number of political and ethical insights that can be drawn from a phenomenology of plurality. This book will appeal to scholars interested in the topics of plurality and intersubjectivity within phenomenology, existentialism, political philosophy, ethics, and feminist philosophy. (shrink)

Many views rely on the idea that it can never be rational to have high confidence in something like, “P, but my evidence doesn’t support P.” Call this idea the “Non-Akrasia Constraint”. Just as an akratic agent acts in a way she believes she ought not act, an epistemically akratic agent believes something that she believes is unsupported by her evidence. The Non-Akrasia Constraint says that ideally rational agents will never be epistemically akratic. In a number of recent papers, the (...) Non-Akrasia Constraint has been called into question.

En Afrique, les religions ancestrales enseignent à chercher sa cohérence intérieure, en restant relié aux autres et à l’univers. Ainsi, chez les Maasaï, la spiritualité peut se traduire par ces lignes de force : vaincre ses peurs, rester relié, ne pas créer de divisions en soi et autour de soi. L’homme doit mettre en adéquation ses mots et ses actes pour éviter la dissonance et les antagonistes, sources de déséquilibres personnel et relationnel. Actes et mots doivent être «jumeaux», aller de (...) paire. Aucune différence entre le dire et le faire chez ces peuples d’Afrique, qui savent par expérience que cette cohérence est la garantie de relations saines et durables. Au-delà des images, l’Afrique est avant tout la terre de la religion.

Epiphanies is a philosophical exploration of epiphanies, peak experiences, 'wow moments', or ecstasies as they are sometimes called. What are epiphanies, and why do so many people so frequently experience them?

How, if at all, do epiphanies fit in with our moral systems and our theories of (...) how to live? And how do epiphanic experiences fit in with the rest of our lives?

During the seventeenth century there were different ways of opposing the new mechanical philosophy and the old Aristotelian philosophy. Remarkably enough, one of this way succeeded in becoming stable beyond the moment of its formulation, one according to which Descartes would be the benchmark by which the works of other natural philosophers of the seventeenth century fall either on the side of the old or the new. I consequently examine the French debate where this representation emerges, a debate that took (...) place along with the development of a Cartesian propaganda in the 1660s and the ensuing official condemnations of the philosophy of Descartes, which was said to constitute a danger for the mystery of Eucharist. But these condemnations pronounced in the name of theology, as numerous and radical as they were, were not considered to be sufficient. They were assisted by numerous polemical works, the audience of which were learned companies of courteous honnêtes gens, and the object of which was to defend a certain way of proceeding in natural philosophy. I consequently concentrate on two correlated questions, the question of what kind of ontological entities are necessary for the establishment of a good physics, and the correlated question of what norms should be adopted in natural philosophy. I show quite systematically that the criticisms of Cartesian philosophers by the Oratorian Jean-Baptiste de La Grange, the bishop Pierre-Daniel Huet, and various Jesuits, Ignace Pardies, Antoine Rochon, Louis Le Valois, Gabriel Daniel, René Rapin, and Honoré Fabri respond to the mockeries of Gérauld de Cordemoy, Jacques Rohault, Louis de La Forge, Bernard Lamy, Nicolas Malebranche or Antoine Arnauld concerning the scholastic entities. Not only do I contrast their philosophical arguments concerning ontological entities and the norms to be respected in physics, but also their ways of defining the philosophical enterprise and its public.

In the history of the scientific revolution, Descartes is often considered as the mechanical philosopher par excellence, and opposed as such to the founder of mechanical science, that is to say, Galileo: this cliché is not without foundation, but it must not make us forget that Descartes was himself a practitioner of mechanical science. In the article "Cartesian Mechanics" I detail the meaning and reach of "mechanics" in the Cartesian corpus, and do so in three steps. 1. I begin by (...) explaining the genesis of the thesis which states that there is no difference between the physical and the mechanical; this thesis is so famous that it is often imagined that it is constituted in Descartes's first writings. But we can in fact show that the first works of Descartes and Beeckman arise from a "physico-mathematical" practice which does not necessarily imply a complete reworking of traditional physics, even if it might have favored the Cartesian ambition for a physics as certain as geometry; it was only in the late 1630s that Descartes began to systematically affirm the identity of physics and mechanics, or of "rules of motion", of "laws of Nature" and of "laws of mechanics". I then analyze the consequences of this affirmation. 2. In the second part of this article I provide a step-by-step commentary of the response proposed by Descartes in a letter to Mersenne in July 1638 to the question raised by Beaugrand's Geostatice (...) dissertatio mathematica (1636), that is to say the question of whether a body weighs more when it is farther from the center of Earth than when it is close. Compared with other texts of the Cartesian corpus, this sample of mechanics has been little analyzed (to my knowledge, the only analyses are those of P. Duhem, P. Costabel, A. Gabbey and D. Garber). This text is nonetheless extremely interesting: Descartes responds to the geostatic question in turn in terms of physics, then mathematics; even more interesting, the examination of the details of his procedures allows us to confront Cartesian statics to other writings, whether those of Guidobaldo del Monte, Galileo, Stevin, Mersenne or Roberval. 3. In the third and final section, I analyze the reasons that lead Descartes to exclude velocity from his statics, I examine the difficulties that his explanation of gravity created for statics, and conclude with the confrontation between mechanical philosophy and mechanical science in the case of Descartes.

The conservation laws do not establish the central premise within the argument from causal overdetermination – the causal completeness of the physical domain. Contrary to David Papineau, this is true even if there is no non-physical energy. The combination of the conservation laws with the claim that there is no non-physical energy would establish the causal completeness principle only if, at the very least, two further causal claims were accepted. First, the claim that the only way that something non-physical could (...) affect a physical system is by affecting the amount of energy or momentum within it, or redistributing the energy and momentum within it. Second, the claim that redistribution of energy and momentum cannot be brought about without supplying energy or momentum. Both of these claims, however, are exceedingly difficult to defend in the context of the argument. (shrink)

The mechanical philosophy that emerged during the Scientific Revolution can be characterised as a reductionism according to which all physical phenomena are to be explained in terms of corpuscles of different sizes, shapes, and motions. It provided early modern natural philosophers with a unified view of nature that contrasted primarily with the Aristotelian view of nature, but also with other naturalist, hermetic, mystic, occultist, Paracelsian, and chymical accounts. Indeed, early modern natural philosophers devised mechanical explanations of almost every kind of (...) phenomena; even supranatural phenomena, such as transubstantiation, or phenomena today described as paranormal, like the action of sympathetic powder on a wound, the influence of the stars on terrestrial events, or the identification of thieves with a divining rod, were given mechanical explanations. Confronting this explanatory deluge, historians adopted two opposing narratives. The first narrative amounted to view the mechanical philosophy as a well-identified category that captured something about early modern natural philosophy. The critical narratives of the last thirty years, however, have deconstructed both the belief that it is an adequate historical category and the conviction that it made a positive contribution to the sciences. First, in an era that privileged microscopic case studies over sweeping panoramas, and emic over etic categories, ‘mechanical philosophy’ came to be thought of as lacking any real descriptive significance. Second, from an evaluative point of view, it has been claimed that the mechanical philosophy had no impact on the development of the new sciences. Considering these descriptive and evaluative challenges, taking the mechanical philosophy at face value is historically inadequate and philosophically naïve. Hence the questions addressed in this chapter: What to do with the mechanical philosophy? Does it have to be dropped completely as a category? And, if not, how is it to be used? My view is that it captures something of the transformations that we put under the umbrella of the Scientific Revolution, but that it is not possible to treat it as a naturally given category. Rather, to be employed usefully, it needs conceptual clarification and historical specification. (shrink)
