The nature of space and time is one of the most fascinating and fundamental areas of the philosophy of physics. This study aims to provide a complete account of current debates in the application of spacetime to string theory. String theory has been an important discipline within physics for many years but is only now being applied to the problems faced by philosophers of science. This emerging area of physics is discussed in relation to a number of theories including general (...) relativity, T-duality and moduli space, and set in the context of current and future research.

It has been argued within some philosophy of quantum gravity circles that endorsing Lewisian modal metaphysics is incompatible with endorsing the fundamental physical ontology of any quantum gravity theory. Speaking concisely, the unsolvable tension would be between Lewis' metaphysical commitment to the fundamentality of space and time, and the physical lesson of quantum gravity about the disappearance of space and time from the fundamental structure of the world. In this essay I argue against the idea that the tension is unsolvable. (...) The analysis does not apply to quantum gravity in general, but only to the specific perspective delivered by quantum string theory. In the first two sections I describe what I think is the general formal payoff of Lewisian possible worlds semantics, and more importantly the general metaphysical payoff generated by some Lewisian metaphysical applications of that formal framework. Lewisian possible worlds semantics is not among the topics of this essay, still a concise presentation of its basic features is required for a more accurate description of the type of modal metaphysics Lewis delivers by applying that formal machinery. The moral of the story in the first two sections is that an attempt of preserving crucial features of Lewisian modal metaphysics, although endorsing the quantum string theory lesson on spacetime non fundamentality, would be not only possible, but also philosophically worthy in a general sense. Then, section three is divided in three parts. In the first part I summarize some formal tools of the methodology used elsewhere - (Vistarini, Routledge, 2019, chapter 6)- to argue for string theory background independence. More precisely, I briefly re-describe some crucial features of a topological-vector bundle structure there defined on a "space" associated to the theory. Such structure is there shown to carry physical and dynamical information about quantum strings systems supporting the thesis of background independence of quantum strings laws (string theory background independence is not a topic of this essay, and the construction of the full formal structure as well as the full argumentative line can be found in the work cited above). The rationale behind the choice of including these formal tools is explained in the second and third parts of section three: that very same topological-fiber bundle structure associated to string theory, if read differently, is shown to also carry structural properties of the Lewisian metaphysical scheme. More precisely, in the second part of section three I attempt to show that such topological-fiber bundle structure owns a topology which qualifies as a plausible accessibility structure extending the Lewisian similarity accessibility. To avoid confusion, I will denote the extended similarity order with S*, or S*-similarity. The latter has some interesting properties. It is quantitatively describable, and even more interestingly its spectrum of variation is a countable one. Then, insofar Lewisian similarity order can be regained from the S*-similarity, one might say that the latter is a metaphysical accessibility relation underlying the former because "more fundamental". As we will see, the explanation of what "more fundamental" means in this metaphysical context mainly involves the idea that the formal nature of S*-similarity, in particular its property of having a countable spectrum of variation, calibrates a metaphysical similarity that reflects the discreteness of the fundamental quantum nature of reality. The extended modal metaphysics with accessibility structure S*-similarity is informed by quantum string physics. Within the extended scheme, the Lewisian claim "things could have been different in countless ways" (Lewis 1973) is an approximate one because only permitted by ordinary language. As soon as one refines the accessibility structure by using the formal language of quantum string theory, it appears things could have been different in countable ways. But the Lewisian variety of alternative states of affairs can be regained from the underlying countable variety via a specific interpretation of the Humean supervenience thesis, one that changes the metaphysical status of the thesis' content and restricts the thesis' domain of application. Finally, in the third part of section three I attempt to show that the same topological-fiber bundle structure used to extend Lewisian similarity has a bundle component producing the formal scheme for a tentative extension of Lewisian nomological accessibility through the lens of string dualities. This will prove to be a non trivial task, and the Lewisian accessibility structure will be regained from the extended one only partially. Finally, the essay contains two short appendices summarizing two argumentative lines outside the main topic of the essay. They briefly describe different ways in which the non fundamentality of spatiotemporal structures can be found in quantum string theory. These sections can be skipped. Nevertheless, they might contribute to understand more robustly the general view endorsed by this essay, i.e. that there isn't any unsolvable tension between Lewis' commitment to the fundamentality of spatiotemporal relations and quantum gravity's lesson about their non fundamentality. -/- .

Weyl symmetry of the classical bosonic string Lagrangian is broken by quantization, with profound consequences described here. Reimposing symmetry requires that the background space-time satisfy the equations of general relativity: general relativity, hence classical space-time as we know it, arises from string theory. We investigate the logical role of Weyl symmetry in this explanation of general relativity: it is not an independent physical postulate but required in quantum string theory, so from a certain point of view it plays only a (...) formal role in the explanation.

Quantum gravity--the marriage of quantum physics with general relativity--is bound to contain deep and important lessons for the nature of physical time. Some of these lessons shall be canvassed here, particularly as they arise from quantum general relativity and string theory and related approaches. Of particular interest is the question of which of the intuitive aspects of time will turn out to be fundamental, and which 'emergent' in some sense.

Physical time plays a different role in general relativity than in quantum mechanics and the particle physics based on it. The first section of this chapter provides a brief survey of the main approaches to quantum gravity and then proceeds to consider the lessons that can be drawn from two distinct strategies for discovering a theory of quantum gravity. In the next section, the chapter first explicates the fate of time in approaches to quantum gravity that start with general relativity (...) (GR) and attempt to quantize it. Second, it investigates approaches to quantum gravity that start from quantum particle physics. The third and fourth sections respectively offer an assessment of time as understood in string theory and 'non‐commutative' field theory. One of the important possibilities for time in quantum gravity is that it might fail to commute with space. (shrink)

This paper explains the phenomenon of `entanglement exchange' within the Bohmian approach to quantum mechanics. After explaining Bohmian mechanics and entanglement exchange, in which pairs of particles become entangled without ever interacting causally in the usual, unitary sense, our aim is to use this example, to illustrate how the `pilot wave' mediates non-local correlations. The discussion thus gives a useful new way to think about entanglement exchange, and clarifies the structure of Bohmian mechanics.

_Abstract_: In this paper we carve out a _reformist_ agenda within the debate on the foundations of cognitive science, incorporating some important ideas from the 4E cognition literature into the computational-representational framework. We are deeply sympathetic to this reformist program since we think that, despite strong criticism of the concept of computation and the related notion of representation, computational models should still be at the core of the study of mind. At the same time, we recognize the need for a (...) liberalization of the computational and representational framework that can address deep dissatisfaction with the anti-biologism and radical internalism of classical cognitive science. However, reform is a difficult task, so in this article we focus on two open questions within the reformist agenda. The first concerns the possibility of combining mechanistic-computational and dynamical explanations. The second concerns related changes in the notion of representation and its use (with special attention to Andy Clark’s radical predictive processing). _Keywords_: Continuum of Representational Genera;_ _Enactivism; Predictive Processing; Radical Embodied Cognition Thesis; Representationalism _ Due problemi aperti nell’agenda riformista della filosofia della scienza cognitiva _ _Riassunto_: In questo lavoro identifichiamo un’agenda _riformista_ nel dibattito sui fondamenti della scienza cognitiva che incorpora alcune idee centrali provenienti dalla letteratura sulla cognizione 4E all’interno di una cornice computazionalista e rappresentazionalista. Tale agenda considera il quadro computazionalista e rappresentazionalista ancora imprescindibile ai fini dello studio integrato della mente e del cervello, ma ne persegue una liberalizzazione nell’intento di renderlo idoneo ad accogliere alcuni importanti spunti emersi dalla letteratura sulla cognizione delle 4E. Tuttavia, riformare è un compito difficile. In questo articolo ci concentriamo su due problemi aperti nell’agenda riformista. Il primo riguarda la possibilità di mettere assieme le spiegazioni meccaniciste e computazionaliste con quelle dinamiche. Il secondo riguarda i cambiamenti relativi alla nozione di rappresentazione e al suo impiego (con particolare attenzione all’elaborazione predittiva radicale di Andy Clark). _Parole chiave_: Continuum dei generi rappresentazionali;_ _Elaborazione predittiva; Enattivismo; Tesi della cognizione incarnata radicale; Rappresentazionalismo.

In this article a neo-Jamesian approach to the self is developed within a naturalistic, bottom-up, and systemic-relational framework. In this approach, consciousness of the body as one’s own body is a necessary precondition of self-consciousness as psychological self-awareness, and hence of a socially and historically situated narrative self. Thus we take on board the criticism of those accounts of the narrative self that pay little attention to embodiment, or go to the extreme of stating that the narrative self is abstract (...) and hence not embodied. But at the same time, we reject the idea that the embodiment of the narrative self is provided by a pre-reflective self-consciousness. By contrast, we view self-consciousness as a construction all the way down, which develops from automatic and pre-reflective processing of representations of objects (object-consciousness), through awareness and then self-awareness of the body, up to introspective self-awareness and then narrative identity. This form of constructivism is a naturalistic reinterpretation of the Hegelian idea that selfhood is socially constructed and self-experience intersubjectively mediated. However, it enables to move away from that blend of narrativism and epiphenomenism that characterizes some strands of the socio-constructivist approach to the narrative self. The storied Me that the selfing process makes is not “empty chatter”, but rather a causally efficacious layer of personality viewed as a self-unifying system. (shrink)

This paper aims to demonstrate how museum collection sustainability is grounded in a range of concrete care practices that are social and material. It explores the unstable nature of heritage materials, drawing on the ecological approach of infrastructure and maintenance studies in the field of art and museums. To do this, I analyse the role of mundane operations in the daily functioning of an exhibition area, presenting data from fieldwork I conducted from 2015–2016 at the Musée du quai Branly in (...) Paris, which preserves collections of art and ethnology from outside Europe. I observed the museum's preventive conservation practices, which work to minimise the risks of material deterioration of heritage objects, focusing attention on stabilising the relationship between objects and their environments. These practices contribute to the construction of the temporalities of museum objects. In exploring the means and devices of preserving these heritage objects, the very assumption of perpetuation is destabilised. Environments continually unfold with the silent material metamorphosis of objects. The exhibition becomes a place of flows, where a multitude of entities circulate and cohabit at different scales, such as insects, dust, and powdery fragments. The daily human work of vacuuming, cleaning, trapping, and measuring provide a set of actions united with other entities engaged in the material life of the exhibited object. As we zoom in on the exhibition space, different timelines emerge that are inextricably linked to the different lives of the museum. (shrink)

The ability of a group of adults with high functioning autism (HFA) or Asperger Syndrome (AS) to distinguish moral, conventional and disgust transgressions was investigated using a set of six transgression scenarios, each of which was followed by questions about permissibility, seriousness, authority contingency and justification. The results showed that although individuals with HFA or AS (HFA/AS) were able to distinguish affect-backed norms from conventional affect-neutral norms along the dimensions of permissibility, seriousness and authority-dependence, they failed to distinguish moral and (...) disgust transgressions along the seriousness dimension and were unable to provide appropriate welfare-based moral justifications. Moreover, they judged conventional and disgust transgressions to be more serious than did the comparison group, and the correlation analysis revealed that the seriousness rating was related to their ToM impairment. We concluded that difficulties providing appropriate moral justifications and evaluating the seriousness of transgressions in individuals with HFA/AS may be explained by an impaired cognitive appraisal system that, while responsive to rule violations, fails to use relevant information about the agent’s intentions and the affective impact of the action outcome in conscious moral reasoning.

The current study provides data about the immediate risk perceptions and psychological effects of the COVID-19 pandemic among Italian participants. A sample of 1034 volunteers answered a web-based survey which aimed to investigate the many facets of risk perceptions connected to COVID-19 (health, work, economy, social and psychological), and risk-related variables such as knowledge, news seeking, perceived control, efficacy of containment measures, and affective states. Socio-demographic characteristics were also collected. Results showed that although levels of general concern are relatively high (...) among Italians, risk perceptions are highest with regards to the economy and work, and lowest concerning health. Cognitive and affective risk-related variables affected the several risk perception domains differently. COVID-19 knowledge did not affect any risk perception while the perceived control decreased health risk likelihood. The other risk-related variables amplified risk perceptions: News seeking increased work-economy risk; efficacy of containment measures increased all perceived risks; negative affective states of fear, anger and sadness increased health and psycho-social risks; anxiety increased only health risk, and uncertainty increased work-economy and psycho-social risk perceptions. Finally, positive affective states increased health risk perception. Socio-psychological implications are discussed. (shrink)

In this study, we investigated the relationships between judgments of intentionality and moral evaluation in individuals with High Functioning Autism (HFA) or Asperger Syndrome (AS). HFA or AS are neurodevelopmental disorders characterised by severe deficits in communication and social functioning. Impairments in Theory of Mind (ToM), i.e., the ability to attribute mental states to oneself and to others, are thought to be the core features of autism. Of all mental states, the concept of ‘intentional action’ is particularly important. People normally (...) distinguish between actions that are performed intentionally and those that are performed unintentionally and this distinction plays a crucial role in social understanding and moral judgment. Recently, Knobe (Analysis 63: 190–193, 2003a ), (Philosophical Psychology 16: 309–324, 2003b ) showed that people’s moral evaluations might serve as input to the process by which people intuitively arrive at the intentionality judgments. Here, by using two pairs of vignettes, the Knobe’s Harm/Help cases and Murder/Bull’s-eye cases, we showed that, as already observed in typical population, in individuals with HFA/AS judgment of intentional action is informed by the moral appreciation of the action outcome. However, the two groups differed on praise judgments and moral justifications, suggesting that these processes were poorly influenced by the agent’s psychological states. We concluded that, although under certain circumstances, individuals with HFA/AS and people with typical development have similar intuitive judgments of intentionality, over-assignment of praise judgments and the reduced use of folk-psychological concepts in moral judgment likely reflect difficulties using intentionality information for moral reasoning.

This paper explores the possibility of applying the theory of Documentality to the photograph, examining it in the context of the photo archive. To this end, I maintain that a photograph’s document value is not determined by its nature, but by its relationship to inscription practices. And I regard the space of the archive as a paradigmatic device that produces cognitive strategies on the word pairing “photograph/photographs” inextricably linked to the inscriptions connected with it, in the form of “archiwritings” and (...) registrations, in essence: with the words of the archive itself.

Background During the first wave of the new coronavirus (COVID-19) pandemic, the sudden increase in hospitalised patients put medical facilities in southern Switzerland under severe pressure. During this time, bachelor’s degree programs in nursing, physiotherapy and occupational therapy were disrupted, and students in their second year were displaced. Students experienced the continuous reorganisation of their traineeship as healthcare facilities adapted to a climate of uncertainty. Purpose The aim of this study was to investigate the degree of moral distress and the (...) ethical issues most often encountered by physiotherapy, nursing and occupational therapy students enrolled in a traineeship during the first wave of the COVID-19 pandemic in southern Switzerland. Participants and research context The sample consisted of 102 participants, and the response rate was 81.6%. Research design Based on a pragmatic approach, a mixed-method with a convergent design was adopted. Data were collected between 30 April 2020 and 14 May 2020, via a survey administered to all occupational therapy, physiotherapy and nursing students in their fourth semester. Ethical considerations Given that no vulnerable persons were involved, the Ethics Committee of Southern Switzerland waived authorisation. However, all measures were put into place to protect participants by guaranteeing their anonymity and confidentiality. Results and discussion The data analysis showed that the main source for moral distress was ‘poor teamwork’ and that the moral issues encountered most often by students were related to the appropriateness of care and working conditions, with a clear reference to students’ own safety and that of their loved ones; the other concerns reported included the loss of learning opportunities and the perceived lack of technical knowledge and skills. Conclusions This survey offers a faithful overview of physiotherapy, nursing and occupational therapy students’ experience during the first pandemic wave. This study also identifies some key recommendations for healthcare professions’ education. (shrink)

Norman in 1969 emphasised a linguistic difference between the Vedic compound yogakṣema- interpreted as a dvandva and the widely distributed Early Buddhist compound yogakkhema-, analysed as a tatpuruṣa “rest from exertion”. On the basis of our analysis of the relevant Pali sources and of the more ancient Vedic occurrences—some of which are quite far from the earliest denotation of the two cyclic phases of the assumed semi-nomadic Indo-Āryan life—we have undertaken a classification of the several meanings of this compound, in (...) order to distinguish their different facets and to enable us to easily bring about the comparison proposed by Norman in 1969 and in 1993 [1991]. Unlike Norman, we eventually postulated a common reading of this compound as a tatpuruṣa originally denoting an almost material target of welfare, from which both the Brāhmaṇic and the Buddhist usages, whose meaning is predominantly immaterial, might have developed.

The ability to resist distracting stimuli whilst voluntarily focusing on a task is fundamental to our everyday cognitive functioning. Here, we investigated how this ability develops, and thereafter declines, across the lifespan using a single task/experiment. Young children (5–7 years), older children (10–11 years), young adults (20–27 years), and older adults (62–86 years) were presented with complex visual scenes. Endogenous (voluntary) attention was engaged by having the participants search for a visual target presented on either the left or right side (...) of the display. The onset of the visual scenes was preceded – at stimulus onset asynchronies (SOAs) of 50, 200, or 500 ms – by a task-irrelevant sound (an exogenous crossmodal spatial distractor) delivered either on the same or opposite side as the visual target, or simultaneously on both sides (cued, uncued, or neutral trials, respectively). Age-related differences were revealed, especially in the extreme age-groups, which showed a greater impact of crossmodal spatial distractors. Young children were highly susceptible to exogenous spatial distraction at the shortest SOA (50 ms), whereas older adults were distracted at all SOAs, showing significant exogenous capture effects during the visual search task. By contrast, older children and young adults' search performance was not significantly affected by crossmodal spatial distraction. Overall, these findings present a detailed picture of the developmental trajectory of endogenous resistance to crossmodal spatial distraction from childhood to old age and demonstrate a different efficiency in coping with distraction across the four age-groups studied.

The beginning of the twentieth century marked the confutation and negation of traditional Chinese values by intellectuals, who thought that Confucianism, and in general traditional Chinese culture, had hindered scientific, economic, and social progress. Nonetheless, we are now witnessing a revival of the tradition, from a political and cultural perspective, aiming to address and provide resolutions to the contradictions and issues of contemporary societies. Which are the most valuable traditions in China today, and what is their impact on Chinese society? (...) This paper will provide some of the theories promoted by Chinese scholars and their interpretation of the role of philosophy and religion today. (shrink)

Brazilian women rely on sterilization as the main source of birth control. Sterilization has been one of the causes of the steep decline in fertility in Brazil, at least since the second half of 1970. It is hypothesized that understanding couples’ relationships might be key to explaining this high rate of female sterilizations. Possible reasons for the higher level of fertility among women in unstable unions than among women in stable ones could be the less effective use of contraceptive methods, (...) or that women in unstable unions tend to use less effective or reversible contraceptive methods. In this paper discrete time modelling of the timing of sterilization according to union histories is presented. The analysis uses the calendar data of the 1996 Brazilian DHS. It is shown that women in second or higher order unions have a lower risk of sterilization. This result should be taken into account in the analysis of the determinants of female sterilization in Brazil. (shrink)

The term ‘moral resilience’ has been gaining momentum in the nursing ethics literature. This may be due to it representing a potential response to moral problems such as moral distress. Moral resilience has been conceptualised as a factor that inhibits immoral actions, as a favourable outcome and as an ability to bounce back after a morally distressing situation. In this article, the philosophical analysis of moral resilience is developed by challenging these conceptualisations and highlighting the risks of such limiting perspectives. (...) It is argued that moral resilience is best understood as a virtue with two associated vices, faintheartedness and rigidity. The intellectual virtue of practical wisdom is required to express resilience as a virtue. This understanding leads to recommendations for professional education, for practice and for further research. (shrink)

The aim of this article is to literally explore the declinations of the status of the “monstruous thing”, investigating if and when monsters are abnormal phenomena, not of nature but of culture. Which features, of both expression and content, must a non-living artificial subject present in order to be perceived and judged as a “monster”? In the West, the image of the monster is traditionally associated with an abominable creature belonging to the universe of nature whose touchstone is a standard (...) unit of measurement associated with a human or animal body. Here, we are interested in seeing what happens when these value judgments about monsters are applied to non-organic entities. Our case study of the large cruise ships, starting with ocean liners and moving toward the modern behemoths that now enter our historic cities, discloses a new semiosis of monstrosity caused by the war of movement produced by globalization.

Review: Daniele Archibugi, The Global Commonwealth of Citizens: Toward Cosmopolitan Democracy, Princeton, Princeton University Press, 2008.

In Feeling of Knowing cases, subjects have a form of consciousness about the presence of a content (such as an item of information) without having access to it. If this phenomenon can be correctly interpreted as having to do with consciousness, then there would be a P-conscious mental experience which is dissociated from access.

This article advances some considerations on the current production of hegemonic effects, starting with some problems posed by the work of one of the most influential writers in cultural studies – the American Palestinian critic Edward Said. Said's commentary on the coverage of Islam in the US media in the late 1970s allows for some challenging considerations on how hegemonic strategies directed at the formation of publics and public opinion are increasingly integrated within a global noopolitics of communication whose understanding (...) of the public is not derived from the notion of civil society but from the biopolitical element of the population – and the bio-racist segmentation that constitutes it. As outlined in Michel Foucault's analysis of liberal and neoliberal governmentality, such understanding of the public locates the latter straight within a new dispositif of power which is biopolitical and noopolitical at the same time, that is, which addresses itself at the same time to the biological, economic and spiritual life of the population. Such understanding involves a reconsideration of the constitution of publics and public opinion in times of netwars and information warfare as both subjects and objects of power/knowledge. In as much as such noopolitics affects what Maurizio Lazzarato calls a second bios, the life of the brain, it has the potential to give expression to the virtual power of immaterial events of subjectification which materialize in the bodies which actualize them and the possible, shared worlds that they are capable of producing.

Handling Religious Diversity: The Case of "Holy/Rest Days" in Italy The accommodation of a plurality of values within the same institutional framework is one of the main challenges with which contemporary democracies have been persistently confronted. This challenge has recently gained strength even in such traditionally homogeneous countries as Italy, as a consequence of an increase in the number of residents committed to diverse religious beliefs. Against this backdrop, this paper focuses on the case of requests for the legal recognition (...) of religion-specific holy/rest days in Italy. The analysis of such a case will disclose—or so we believe—some valuable pointers as to how democratic societies could try to accommodate religious diversity in a way that is both respectful of the specificities of each religious group and compatible with the typically liberal commitment to the safeguard of individual freedom.
