The brain adapts to changes that take place in the body. Deprivation of input results in size reduction of cortical representations, whereas an increase in input results in an increase of representational space. Amputation forms one of the most dramatic disturbances of the integrity of the body. The brain adapts in many ways to this breakdown of the afferent–efferent equilibrium. However, almost all studies focus on the sensorimotor consequences. It is not known whether adaptation takes place also at other “levels” (...) in the system. The present study addresses the question whether amputees dream about their intact body, as before the amputation, or about the body after the amputation and whether the dream content was a function of time since the amputation and type of amputation. The results show that the majority of the dreamers reported dreams about their intact body although the mean time that elapsed since the amputation was twelve years. There is no clear relation with the type of amputation. The results give modest evidence for the existence of a basic neural representation of the body that is, at least, partly genetically determined and by this relatively insensitive for changes in the sensory input.

Argumentation as the public exchange of reasons is widely thought to enhance deliberative interactions that generate and justify reasonable public policies. Adopting an argumentation-theoretic perspective, we survey the norms that should govern public argumentation and address some of the complexities that scholarly treatments have identified. Our focus is on norms associated with the ideals of correctness and participation as sources of a politically legitimate deliberative outcome. In principle, both ideals are mutually coherent. If the information needed for a correct deliberative (...) outcome is distributed among agents, then maximising participation increases information diversity. But both ideals can also be in tension. If participants lack competence or are prone to biases, a correct deliberative outcome requires limiting participation. The central question for public argumentation, therefore, is how to strike a balance between both ideals. Rather than advocating a preferred normative framework, our main purpose is to illustrate the complexity of this theme. (shrink)

This paper focuses on the importance of wonder in human flourishing and is orientated towards the dynamics between the two, but with an emphasis on how the former is important for illuminating the latter. It begins with a preliminary sketch of both wonder and human flourishing and subsequently moves on to highlight three aspects of human flourishing: 1) ‘Individuality’, 2) ‘Relations’ and 3) ‘The political’, and why these play to wonderment.

Microbiota-gut-brain research is a fast-growing field of inquiry with important implications for how human brain function and behaviour are understood. Researchers manipulate gut microbes to reveal connections between intestinal microbiota and normal brain functions or pathological states. Many claims are made about causal relationships between gut microbiota and human behaviour. By uncovering these relationships, MGB research aims to offer new explanations of mental health and potential avenues of treatment. So far, limited evaluation has been made of MGB's methods and its (...) core experimental findings, many of which are extensively reiterated in copious reviews of the field. These factors, plus the self-help potential of MGB, have combined to encourage uncritical public uptake of MGB discoveries. Both social and professional media focus on the potential for dietary intervention in mental health, and causal relationships are assumed to be established. Our target article has two main aims. One is to examine critically the core practices and findings of experimental MGB research and to raise questions about them for brain and behavioural scientists who may not be familiar with the field. The other is to challenge the way in which MGB findings are presented. Our positive goal is to suggest how current problems and weaknesses may be addressed, in order for both scientific and public audiences to gain a clearer picture of MGB research and its strengths and limitations.

Graphical AbstractCephalopods provide a unique model system to investigate how organismal novelties evolve. In article number 1900073, Elena A. Ritschard et al. discuss how co-evolutionary signatures among various genomic characters have contributed to cephalopod organismal novelties and can be used to dissect their functional organization. Cover illustration by Hannah Schmidbaur.

How genomic innovation translates into organismal organization remains largely unanswered. Possessing the largest invertebrate nervous system, in conjunction with many species‐specific organs, coleoid cephalopods (octopuses, squids, cuttlefishes) provide exciting model systems to investigate how organismal novelties evolve. However, dissecting these processes requires novel approaches that enable deeper interrogation of genome evolution. Here, the existence of specific sets of genomic co‐evolutionary signatures between expanded gene families, genome reorganization, and novel genes is posited. It is reasoned that their co‐evolution has contributed to (...) the complex organization of cephalopod nervous systems and the emergence of ecologically unique organs. In the course of reviewing this field, how the first cephalopod genomic studies have begun to shed light on the molecular underpinnings of morphological novelty is illustrated and their impact on directing future research is described. It is argued that the application and evolutionary profiling of evolutionary signatures from these studies will help identify and dissect the organismal principles of cephalopod innovations. By providing specific examples, the implications of this approach both within and beyond cephalopod biology are discussed. (shrink)

Health technology assessment (HTA) is often biased in the sense that it neglects relevant perspectives on the technology in question. To incorporate different perspectives in HTA, we should pursue agreement about what are relevant, plausible, and feasible research questions; interactive technology assessment (iTA) might be suitable for this goal. In this way a kind of procedural ethics is established. Currently, ethics too often is focussed on the application of general principles, which leaves a lot of confusion as to what really (...) is the matter in specific cases; in an iTA clashes of values should not be approached by use of such ethics. Instead, casuistry, as a tool used within the framework of iTA, should help to articulate and clarify what is the matter, as to make room for explication and consensus building. (shrink)

In Balanced Wonder, Jan B. W. Pedersen digs deep into the alluring topic of wonder, in dialogue with Neo-Aristotelian philosophers, arguing that the experience of wonder, when balanced, serves as a strong contributor to human flourishing.

This study investigates potential differences in attitudes towards corporate social responsibility between Saudis and Muslims from other predominately Islamic countries. We propose that Saudi Arabia’s unique rentier-state welfare and higher education systems account for these distinctions. In evaluating our propositions, we replicate Brammer et al. :229–243, 2007) survey on attitudes towards CSR using a sample of Saudi undergraduate and graduate business students and compare the results against data from subjects in other majority Muslim countries. In addition, this work examines possible (...) differences within the Saudi sample with respect to sex and academic level. Our results indicate that our Saudi subjects maintain higher expectations for corporations’ social responsibility within their supply chain than the Brammer et al.’s sample. In contrast, Muslims in the Brammer et al.’s sample hold higher expectations for corporations in supporting societal development and poverty alleviation in comparison to the Saudi sample. We also find within the Saudi sample that females and subjects at higher academic levels are more inclined to hold corporations responsible for social issues related to CSR than males and subjects in lower academic levels. We examine these findings, explore their implications, and propose areas for future research. (shrink)

One of the vexed questions in the philosophy of wonder and indeed education is how to ensure that the next generation harbours a sense of wonder. Wonder is important, we think, because it encour- ages inquiry and keeps us as Albert Einstein would argue from ‘being as good as dead’ or ‘snuffed-out candles’ (Einstein 1949, 5). But how is an educator to install, bring to life, or otherwise encourage a sense of wonder in his or her stu- dents? Biologist Rachel (...) Carson suggests that exploring nature and specifically undertaking walks along the rocky coast of Maine would keep alive a person’s inborn sense of wonder (Carson 1984). Philosopher Jesse Prinz thinks that exposure to art will encourage wonderment because artworks, as he puts it, are “inventions for feeding the appetite that wonder excites in us” (Prinz 2013). Weird fiction (a subgenre of speculative fiction) – and in particular the work of one of its greatest exponents, the early-20th-century American author How- ard Phillips Lovecraft – is likewise a catalyst for wonder. The reason behind this is that Lovecraft’s ‘wonder-stories’ are densely packed with wonder per design; and in support of this claim I shall in what is to come 1) provide a brief introduction to Lovecraft and weird fiction; 2) present a working definition of wonder; and 3) clarify what is meant by something being ‘densely packed with wonder’ via bringing to the fore evidence of Lovecraft’s literary wonder- mongery. The paper ends with some reflections on the notion of ‘dark wonder’, why this peculiar label might be suitable for the kind of wonder we find in Lovecraft’s work, and why exposure to ‘dark wonder’ can be edifying, and in that sense educational.

In 2014, the editorial board of BMC Medical Ethics came together to devise sections for the journal that would give structure to the journal help ensure that authors’ research is matched to the most appropriate editors and help readers to find the research most relevant to them. The editorial board decided to take a practical approach to devising sections that dealt with the challenges of content management. After that, we started thinking more theoretically about how one could go about classifying (...) the field of medical ethics. This editorial elaborates and reflects on the practical approach that we took at the journal, then considers an alternative theoretically derived approach, and reflects on the possibilities, challenges and value of classifying the field more broadly.

Our analysis of microbiota-gut-brain research took MGB to task for some of its methods, concepts, and interpretations. Commentators then raised numerous issues about the neuroscientific and microbiome aspects of MGB and how it can be understood as a field. We respond by addressing the dimensionality and causal focus of MGB.

Howard Phillips Lovecraft’s work of fiction can roughly be grouped into three distinct categories, each evoking a singular extraordinary state of mind. Poe-inspired tales of the macabre such as “The Tomb” (1917) and “The Statement of Randolph Carter” (1919) produce terror because of the atmosphere they convey and because of the particular end the main characters meet. Lovecraft’s later “Yog-Sothothery” or work in the Cthulhu Mythos tradition, including his signature pieces of weird fiction “The Call of Cthulhu” (1926) and “The (...) Shadow over Innsmouth” (1931), inspires ‘horror’ because the life-worlds of the protagonists in these stories are utterly destroyed. However, the gentleman of Providence is also known for a different sort of fiction. His Dunsanian tales—among them short stories such as “The White Ship” (1919), “Celephaïs” (1920), and the three works“ The Silver Key” (1926), The Dream-Quest of Unknown Kadath (1926–27), and “Through the Gates of the Silver Key” (1932–33; with E. Hoffmann Price), centered on the exploits of Lovecraft’s recurring character and alter ego Randolph Carter—are epitomes to this feat. These prehistoric or dreamland tales do not inspire ‘terror’ or ‘horror’; rather, they predominately seek to evoke the extraordinary state of mind called ‘wonder. This article offers a preliminary exploration of Lovecraft’s relationship with wonder, highlights what wonder is, how Lovecraft was exposed to wonder at an early age, and argues that he developed a lifelong positive relationship with this particular state of mind.

Burkart et al. present a paradox – general factors of intelligence exist among individual differences (g) in performance in several species, and also at the aggregate level (G); however, there is ambiguous evidence for the existence of g when analyzing data using a mixed approach, that is, when comparing individuals of different species using the same cognitive ability battery. Here, we present an empirical solution to this paradox.

This handbook presents a comprehensive introduction to the core areas of philosophy of education combined with an up-to-date selection of the central themes. It includes 95 newly commissioned articles that focus on and advance key arguments; each essay incorporates essential background material serving to clarify the history and logic of the relevant topic, examining the status quo of the discipline with respect to the topic, and discussing the possible futures of the field. The book provides a state-of-the-art overview of philosophy (...) of education, covering a range of topics: Voices from the present and the past deals with 36 major figures that philosophers of education rely on; Schools of thought addresses 14 stances including Eastern, Indigenous, and African philosophies of education as well as religiously inspired philosophies of education such as Jewish and Islamic; Revisiting enduring educational debates scrutinizes 25 issues heavily debated in the past and the present, for example care and justice, democracy, and the curriculum; New areas and developments addresses 17 emerging issues that have garnered considerable attention like neuroscience, videogames, and radicalization.

Plutarch was a brilliant Platonist, an erudite historian, a gifted author of highly polished literary dialogues, a priest of Apollo at Delphi, and a devoted politician in his hometown Chaeronea. He felt confident in the most technical and specialized discussions, yet was not afraid of rhetorical generalizations. In his voluminous oeuvre, he appears as a sharp polemicist and a loving father, an ardent pupil but also a kind, inspiring teacher, a sober historian and a teller of wondrous tales. In view (...) of all these different personae, erudite versatility is without any doubt a major characteristic of Plutarch’s works. A Versatile Gentleman is dedicated to Luc Van der Stockt, professor emeritus of Greek language and literature at KU Leuven and a truly versatile gentleman. The volume aims to do justice to his and Plutarch’s versatility by discussing the Chaeronean from many different angles. As such, it sheds new light on the coherence of, and the tensions in, Plutarch’s thinking and writing. (shrink)

In earlier writings, I have sought to establish a link between Howard Phillips Lovecraft and Romanticism, and this paper adds to that body of work. -/- The essay begins with a preliminary sketch of the use of gardens in Romantic thought and the highlighting of six themes: contemplation, joy, the dramatic, the strange, the foreign, and the beautiful, that all underpins Romanticism. -/- This is followed by an elucidation of Lovecraft’s fascination with gardens, his dealings in Romantic themes, and what (...) role they play in his short 1917 poem “A Garden”. -/- The essay concludes that given Lovecraft’s love of gardens and that his poem “A Garden” is imbued with Romantic themes and involves ‘wondrous contemplation’ and ‘poetic knowledge’, the case for his Romanticism has been strengthened.

Howard Phillips Lovecraft can be viewed as a Romantic based on his lifelong relationship with wonder. This short essay gathers further evidence of Lovecraft’s Romanticism, beginning with a brief exploration of what Romanticism is and then moving on to highlight elements of Romanticism in Lovecraft’s poem “Fact and Fancy” (1917). The essay concludes that, as much as Lovecraft can be labelled a Romantic based on his affinity with wonder, he can also be classified as such based on his aversion to (...) the cold light of reason, which to him was an insufficient antidote to the otherwise dreary world in which he found himself.

Lovecraft’s teetotalism is well known among Lovecraftians, but the lengths to which he went to incorporate his views and how he sought to influence the people around him via his various writing remain relatively unexplored. This essay focuses on Lovecraft’s teetotalism and opens with a brief sketch of the historical background from which his dry outlook emerged. It continues by providing evidence for Love- craft’s advocacy of abstinence and Prohibition from a variety of sources, including biographical material, philosophical essays, letters, (...) poetry, and fiction, with a view to showing how he communicated his dry philosophy and how it softened as he advanced into middle age. The essay ends by arguing that although there can be no doubt that Lovecraft was a teetotaler par excellence, his later softened position is more balanced and rooted partly in the realization of his own idiosyncrasy and anachronism.

Each contributor to this book has used personal experience as the basis from which to frame his individual sociological perspectives. Because they have personalized their work, their accounts are real, and recognizable as having come from 'real' persons, about 'real' experiences. There are no objectively-distanced disembodied third person entities in these accounts. These writers are actual people whose stories will make you laugh, cry, think, and want to know more.

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multi-national data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from (...) social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution—individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar was found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-negligible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic. (shrink)

According to a two-level criterion for combination tests in the field of ordinary language, moral 'ought'-sentences may be taken to imply 'I intend'-sentences partly semantically and partly pragmatically. If so, a trenchant linguistic analysis of the concept of moral obligation cannot do without a non-classical logic which allows to model these important kinds of ordinary-language implications by means of purely syntactical derivations. For this purpose, an integrated logic of conviction and intention has been tentatively devised by way of a doxastically, (...) buletically, and pragmatically extended calculus of natural deduction. This system of buletic logic cannot even be launched without one or two derivation rules of deductive closedness. However, these very closedness rules appear to be responsible for buletic paradoxes which are analogous to paradoxes long since known from other, less exotic branches of logic but at first sight look much more virulent. After having scrutinized two potential strategies for coping with the paradoxes of buletic logic, finally we can convince ourselves that these paradoxes, as well as their familiar non-buletic counterparts, are but apparent paradoxes, provided we consistently lean on C-CT and do not let pragmatical considerations intrude into purely logical ones.

Influential theories on affect and emotion propose a fundamental differentiation between emotion and cognition, and research paradigms designed to test them focus on differences rather than similarities between affective and cognitive processes. This research orientation is increasingly challenged by the widespread and successful use of cognitive research paradigms in the study of affect and emotion—a challenge with far-reaching implications. Where and on what basis should theorists draw the line between cognition and emotion, and when is it useful to do so? (...) Should researchers build more global, integrative models of cognition and emotion, or should they rely on local, content-specific models that draw attention to a differentiation between affective and cognitive processes? This special issue compiles different viewpoints on fundamental issues in the relationship between affect and cognition. (shrink)

It is generally believed that the uncertainty relation Δq Δp≥1/2ħ, where Δq and Δp are standard deviations, is the precise mathematical expression of the uncertainty principle for position and momentum in quantum mechanics. We show that actually it is not possible to derive from this relation two central claims of the uncertainty principle, namely, the impossibility of an arbitrarily sharp specification of both position and momentum (as in the single-slit diffraction experiment), and the impossibility of the determination of the path (...) of a particle in an interference experiment (such as the double-slit experiment).The failure of the uncertainty relation to produce these results is not a question of the interpretation of the formalism; it is a mathematical fact which follows from general considerations about the widths of wave functions.To express the uncertainty principle, one must distinguish two aspects of the spread of a wave function: its extent and its fine structure. We define the overall widthW Ψ and the mean peak width wψ of a general wave function ψ and show that the productW Ψ w φ is bounded from below if φ is the Fourier transform of ψ. It is shown that this relation expresses the uncertainty principle as it is used in the single- and double-slit experiments. (shrink)

Research in social robotics is commonly focused on designing robots that imitate human behavior. While this might increase a user’s satisfaction and acceptance of robots at first glance, it does not automatically aid a non-expert user in naturally interacting with robots, and might hurt their ability to correctly anticipate a robot’s capabilities. We argue that a faulty mental model, that the user has of the robot, is one of the main sources of confusion. In this work, we investigate how communicating (...) technical concepts of robotic systems to users affect their mental models, and how this can increase the quality of human-robot interaction. We conducted an online study and investigated possible ways of improving users’ mental models. Our results underline that communicating technical concepts can form an improved mental model. Consequently, we show the importance of consciously designing robots that express their capabilities and limitations. (shrink)

Working memory is the system responsible for maintaining and manipulating information, in the face of ongoing distraction. In turn, WM span is perceived to be an individual-differences construct reflecting the limited capacity of this system. Recently, however, there has been some evidence to suggest that WM capacity can increase through training, raising the possibility that training can functionally alter the neural structures supporting WM. To address the hypothesis that the neural substrates underlying WM are targeted by training, we conducted a (...) meta-analysis of functional magnetic resonance imaging studies of WM training using Activation Likelihood Estimation. Our results demonstrate that WM training is associated exclusively with decreases in blood oxygenation level-dependent responses in clusters within the fronto-parietal system that underlie WM, including the bilateral inferior parietal lobule, middle and superior frontal gyri, and medial frontal gyrus bordering on the cingulate gyrus. We discuss the various psychological and physiological mechanisms that could be responsible for the observed reductions in the BOLD signal in relation to WM training, and consider their implications for the construct of WM span as a limited resource.

Sleep strengthens memories by repeatedly reactivating associated neuron ensembles. Our studies show that although long-term memory for a medium number of word-pairs benefits from sleep, a large number does not. This suggests an upper limit to the amount of information that has access to sleep-dependent declarative memory consolidation, which is possibly linked to the availability of reactivation opportunities. Due to competing processes of global forgetting that are active during sleep, we hypothesized that even larger amounts of information would enhance the (...) proportion of information that is actively forgotten during sleep. In the present study, we aimed to induce such forgetting by challenging the sleeping brain with vast amounts of to be remembered information. For this, 78 participants learned a very large number of 640 word-pairs interspersed with periods of quiet awake rest over the course of an entire day and then either slept or stayed awake during the night. Recall was tested after another night of regular sleep. Results revealed comparable retention rates between the sleep and wake groups. Although this null-effect can be reconciled with the concept of limited capacities available for sleep-dependent consolidation, it contradicts our hypothesis that sleep would increase forgetting compared to the wake group. Additional exploratory analyses relying on equivalence testing and Bayesian statistics reveal that there is evidence against sleep having a detrimental effect on the retention of declarative memory at high information loads. We argue that forgetting occurs in both wake and sleep states through different mechanisms, i.e., through increased interference and through global synaptic downscaling, respectively. Both of these processes might scale similarly with information load. (shrink)

Agriculture in Western Europe has become efficient and productive but at a cost. The quality of biodiversity, soil, air, and water has been compromised. In the search for ways to ensure food security and meet the challenges of climate change, new production systems have been proposed. One of these is the transition to circular agriculture: closing the cycles of nutrients and other resources to minimise losses and end the impact on climate change. This development aims to address existing problems in (...) food production but also raises questions about animal health and welfare. Although the role animals can play in this development is not ignored, the animal welfare dimension of circular agriculture seems to be overlooked. We argue that this is a problem both for the success of circular agriculture and for the animals involved. To substantiate this claim, we analyse the background to this lack of attention, which we find in (a) the way circular agriculture is conceptualised; (b) the institutional hurdles related to the legal, political and economic context; and (c) the concept of animal welfare, which requires further innovation. By analysing these aspects, we develop stepping stones for an animal-welfare inclusive concept of circular agriculture. These stepping stones include: recognising the animal as a participant with its own interests in the innovation towards circular agriculture; using a dynamic concept of animal welfare; a concept of circularity that provides space for social values, including animal welfare; and attention to institutional innovation by improving public engagement and building trust.

Steels & Belpaeme (S&B) are clearly interested in the possible test their models may provide for human language theories. However, they only superficially address the assumptions underlying their own agent architecture, while these are of crucial relevance to the topic of human language. These assumptions fit an Augustinian picture of language, which Wittgenstein challenges in his Philosophical Investigations. It is too early to draw conclusions regarding human language evolution from such models.
