Noncommutative geometries generalize standard smooth geometries, parametrizing the noncommutativity of dimensions with a fundamental quantity with the dimensions of area. The question arises then of whether the concept of a region smaller than the scale—and ultimately the concept of a point—makes sense in such a theory. We argue that it does not, in two interrelated ways. In the context of Connes’ spectral triple approach, we show that arbitrarily small regions are not definable in the formal sense. While in the scalar (...) field Moyal–Weyl approach, we show that they cannot be given an operational definition. We conclude that points do not exist in such geometries. We therefore investigate the metaphysics of such a geometry, and how the appearance of smooth manifold might be recovered as an approximation to a fundamental noncommutative geometry. (shrink)

I will discuss some aspects of the concept of “point” in quantum gravity, using mainly the tool of noncommutative geometry. I will argue that at Planck’s distances the very concept of point may lose its meaning. I will then show how, using the spectral action and a high momenta expansion, the connections between points, as probed by boson propagators, vanish. This discussion follows closely.

Philosophy for Children (P4C) is an approach to learning and teaching that aims to develop reasoning and judgement. Students learn to listen to and respect their peers' opinions, think creatively and work together to develop a deeper understanding of concepts central to their own lives and the subjects they are studying. With the teacher adopting the role of facilitator, a true community develops in which rich and meaningful dialogue results in enquiry of the highest order. Each chapter is written by (...) a leading P4C expert and provides an introduction to the relationship between P4C and the subject area, lesson stimuli and activities for extending and deepening students' thinking. The book includes: • guidance on how to embed P4C in curriculum subjects in a crowded and demanding secondary curriculum timetable • troubleshooting advice for the teacher-turned-facilitator • a companion website containing useful links, downloadable resources and material to display on your interactive whiteboard. Edited and collated by the UK's leading P4C organisation, this book introduces a rationale for using and adapting P4C in the secondary curriculum. (shrink)

This paper explores the application of ethic of care principles to research practice. It reflects on a research partnership between a voluntary-sector organisation (VSO) for older people and a university research centre (URC). The focus is a participatory research project on older people and well-being in which older volunteers were involved as co-researchers. The shared values of the VSO's culture of practice and the participatory approach of the university researchers have enabled joint research projects to be developed within an ethic (...) of care framework. The model sought to break down the barriers between expert and lay knowledge and encouraged the mutual recognition, sharing and validating of different areas of expertise. An ethic of care framework offers context-specific ways of understanding and responding to the ethical challenges of undertaking participatory research, and to the relational aspects of well-being identified by older people during the course of the work.

This book is written by a philosopher for other philosophers and for that section of the reading public who buy in large quantities and, no doubt, devour with great earnestness the popular books written by scientists for their enlightenment. We common readers, to adapt a phrase from Samuel Johnson, are fitted neither to criticize physical theories not to decide what precisely are their implications. We are dependent upon the scientists for an exposition of those developments which - so we find (...) them proclaiming - have important and far-reaching consequences for philosophy. Unfortunately, however, our popular expositors do not always serve us very well. The two who are most widely read in this country are Sir Arthur Eddington and Sir James Jeans. They are not always reliable guides. Their influence has been considerable upon the reading public, upon theologians, and upon preachers; they have even misled philosopher who should have known better. Accordingly, it has seemed to me to be worth while to examine in some detail the philosophical views that they have put forth and to criticize the grounds upon which these views are based. (shrink)

This article explores the impact of structural and technological change on women's employment in the UK television industry. It looks at the challenges faced by women in working in what has become since the mid-1980s a largely freelance industry where short-term contracts, informal recruitment procedures and long, unpredictable work schedules mean that women find it increasingly difficult to combine a career and family. Through case studies of individual careers, of a women's magazine programme for S4C Digital and a survey of (...) women's credits on a selection of the newer channels, it argues that technological advances in digital transmission and production will not improve working conditions and opportunities for women's participation in all areas of the industry if they continue to replicate existing practice.

First published in 1943, and revised for this 1952 edition, this book was intended for use by students of philosophy and as such traditional and modern developments in logic have been combined in a unified treatment. The author envisaged this volume as filling a gap for a simple, introductory text on formal logic, written from a modern point of view, unencumbered by traditional doctrine. This title provides a thorough introduction and grounding in the philosophy of logic, and was later revised (...) after the author’s death to correct a number of logical errors — making this edition the most complete version of the work.

Originally published in 1914, this book examines the French Voluntarist school of philosophy and the key ways in which it differs from the Pragmatists. Stebbing argues that Voluntarism and Pragmatism both prove inadequate in their definition of truth, and suggests that an acknowledgment of the 'non-existential character of truth' is needed. This book will be of value to anyone with an interest in philosophy.

The problem of deep inequality that the pandemic exacerbated and made visible demands the search for educational policies and proposals that alter and transform school grammar, conceptions about teaching and learning, institutional cultures, and the redefinition of the meaning of school. It is suggested here that we are living a pivotal moment in history, in which to reconstruct school experiences that guarantee the expansion and fulfillment of the right to education.

This paper explores the presence of late medieval ius commune in Grotius’s thought on the use of force in internal strife and war, based on De iure belli ac pacis. To this end, it examines Grotius’s use of ius commune sources, and considers some similar sources, which he does not actually cite, but which relate to his discussion. By clarifying Grotius’s selection and use of ius commune sources, the paper intends to contribute to the achievement of a double aim: firstly, (...) to determine the place of rebellion and civil war in De iure belli ac pacis, especially in relation to war; and, secondly, to assess Grotius’s approach to the two former issues, particularly with regard to the criteria by which a distinction between rebellion and civil war can be drawn, and to the effects of this distinction.

Originally published in 1934. This fourth edition originally published 1954., revised by C. W. K. Mundle. "It must be the desire of every reasonable person to know how to justify a contention which is of sufficient importance to be seriously questioned. The explicit formulation of the principles of sound reasoning is the concern of Logic". This book discusses the habit of sound reasoning which is acquired by consciously attending to the logical principles of sound reasoning, in order to apply them (...) to test the soundness of arguments. It isn't an introduction to logic but it encourages the practice of logic, of deciding whether reasons in argument are sound or unsound. Stress is laid upon the importance of considering language, which is a key instrument of our thinking and is imperfect. (shrink)

In the Netherlands, in 2002, euthanasia became a legitimate medical act, only allowed when the due care criteria and procedural requirements are met. Legally, an Advanced Euthanasia Directive can replace direct communication if a patient can no longer express his own wishes. In the past decade, an exponential number of persons with dementia share a euthanasia request with their physician. The impact this on physicians, and the consequent support needs, remained unknown. Our objective was to gain more insight into the (...) experiences and needs of Dutch general practitioners and elderly care physicians when handling a euthanasia request from a person with dementia. We performed a qualitative interview study. Participants were recruited via purposive sampling. The interviews were transcribed verbatim, and analyzed using the conventional thematic content analysis. Eleven general practitioners and elderly care physicians with a variety of experience and different attitudes towards euthanasia for PWD were included. Euthanasia requests appeared to have a major impact on physicians. Difficulties they experienced were related to timing, workload, pressure from and expectations of relatives, society’s negative view of dementia in combination with the ‘right to die’ view, the interpretation of the law and AEDs, ethical considerations, and communication with PWD and relatives. To deal with these difficulties, participants need support from colleagues and other professionals. Although elderly care physicians appreciated moral deliberation and support by chaplains, this was hardly mentioned by GPs. Euthanasia requests in dementia seem to place an ethically and emotionally heavy burden on Dutch GPs and elderly care physicians. The awareness of, and access to, existing and new support mechanisms needs further exploration. (shrink)

Le livre de Gianvito Brindisi se propose d’étudier la pensée de Michel Foucault en essayant de mettre en lumière la multiplicité des perspectives qu’elle offre pour l’élaboration d’une généalogie des pratiques de jugement dans le champ juridique et moral. L’analyse du droit comme pratique et exercice de vérité, comme instrument de partage et de gouvernement des conduites et comme lieu de constitution des subjectivités nous permet, selon Brindisi, de tirer du travail foucaldien une aide précie...

O artigo apresenta uma investigação, no âmago do pensamento de Nicolau Maquiavel, sobre o papel que os conflitos romanos ocorridos entre nobres e plebe tiveram para que a República de Roma se tornasse uma potência militar. O entrechoque de desejos de grandes e povo foi responsável por promover naquela cidade um autêntico vivere civile e libero, mas também foi a principal causa de sua expansão político-militar. Aqui, buscaremos elucidar os motivos que alçaram Roma àquela grandeza. Em um primeiro lugar, as (...) dissensões ocasionaram o aperfeiçoamento constitucional das instituições romanas, encaminhando-as rumo a um estado republicano de governo misto. Com a instituição dos Tribunos da Plebe, o povo alcançava seu reconhecimento político, possibilitando que os exércitos fossem formados pelos próprios cidadãos advindos da plebe. Em segundo lugar, a regulação institucional dos conflitos e o anseio expansionista de Roma foram a razão pela qual a "guarda da liberdade" havia sido confiada à plebe, promovendo um governo popular, medida que permitiu que a República se voltasse para campanhas expansionistas em direção a conquista do império. Em terceiro lugar, reconhecer o conflito e institucionalizá-lo foi um meio para precaver-se dos caprichos da fortuna. Dessa forma, regular institucionalmente os eventos que atribulam a ordem política interna significava dar garantias para que os confrontos externos fossem bem-sucedidos. (shrink)

There is a death by suicide in the world every 40 seconds, and suicide is the second leading cause of death for 15–29-year-olds. Experts say that one of the best ways to prevent suicide is for those in distress to hear from people who care about them. Facebook is in a unique position—through its support for networks and friendships on the site—to help connect a person in these difficult situations with people who can support them. Connecting people with the resources (...) they need is part of Facebook’s ongoing efforts to help build a safe community inside and outside of Facebook. This article provides a brief overview of how Facebook’s work to develop suicide prevention tools started and evolved, and the ethical considerations which surfaced during the process in the form of concrete product decisions around the implementation of these tools. This article is structured into three sections. Section 1 reviews what has been done in this space and lists and briefly describes other suicide prevention apps and tools. Section 2 describes Facebook’s overall approach to suicide prevention. Here, we’ll delve first into how that approach originated and how it was influenced by the external community’s proactive interactions with Facebook, highlighting our unique position to help address the problem. Afterwards, we’ll explain how that approach evolved, describing its various stages and iterations: understanding, reactive reporting, queue prioritization, and proactive reporting. This section describes the tools and resources Facebook has developed for people who may be at risk. Particular attention is devoted to the use of ArtificiaI Intelligence and Machine Learning to detect posts or live videos where someone might be expressing thoughts of suicide. Section 3 will elaborate on the ethical questions addressed when developing our approach and when making concrete product decisions to implement our suicide prevention tools. In this last section, we’ll expound the competing values and interests that were at stake during the product development process, and how we reached ethical balances between them. (shrink)

A key challenge when learning language in naturalistic circumstances is to extract linguistic information from a continuous stream of speech. This study investigates the predictors of such implicit learning among adults exposed to a new language in a new modality. Sign-naïve participants were shown a 4-min weather forecast in Swedish Sign Language. Subsequently, we tested their ability to recognise 22 target sign forms that had been viewed in the forecast, amongst 44 distractor signs that had not been viewed. The target (...) items differed in their occurrence frequency in the forecast and in their degree of iconicity. The results revealed that both frequency and iconicity facilitated recognition of target signs cumulatively. The adult mechanism for language learning thus operates similarly on sign and spoken languages as regards frequency, but also exploits modality-salient properties, for example iconicity for sign languages. Individual differences in cognitive skills and language learning background did not predict recognition. The properties of the input thus influenced adults’ language learning abilities at first exposure more than individual differences. (shrink)

Clarke and Beck discuss in their sections on congruency and confounds literature that has challenged the claim that the approximate number system represents numerical content. We argue that the propositions put forward by these studies aren't that far from the indirect model of number perception suggested by C&B.

Kim Longinotto is one of the UK's leading documentary directors whose body of work explores women's lives and their struggles for autonomy and human rights in a range of international cultural contexts. Her strategies interrogate the observationalist traditions of documentary cinema and visual anthropology to produce engaged and profoundly empathetic feminist films. She works in collaborative ways with her subjects, often with other directors, to represent the contradictions and multiple layers of their lives and political and social situations. This interview (...) focuses on Longinotto's approach to representing her subjects and using the medium of documentary as a form of witnessing. (shrink)

L’intento del lavoro è di problematizzare alcuni aspetti, generalmente ritenuti emblematici, della relazione tra i litterati medievali e il libro – nelle sue declinazioni di Testo sacro, Libro della natura e auctoritates . L’impiego, come strumenti di lavoro, di concetti di recente elaborazione e di osservazioni di pensatori contemporanei sull’argomento, non è finalizzato ad attualizzare tale relazione, quanto piuttosto ad ampliare i punti di vista su di essa e a metterne alla prova la capacità di offrire originali spunti di riflessione. (...) Le proposte teoriche di Jacques Derrida, Michel Foucault e Roland Barthes sono qui adoperate come esemplificazioni di un’interpretazione che ha storicamente reso quasi paradigmatico il modo di leggere dei docti , specialmente altomedievali. Tuttavia, alcune definizioni della Scrittura – il libro per eccellenza – proposte da questi ultimi, nonché la teorizzazione del suo quadruplice senso sembrano smussare la radicalità di queste osservazioni. Concetti quali “funzione-autore” di Foucault e “testo” di Barthes sono invece adottati per considerare all’interno di una diversa cornice teorica il confronto dei doctores , in particolare bassomedievali, con le cosiddette auctoritates . Nella visione ordinaria la reverenza nei confronti dell’autore, divino o umano, la ricerca e la riproposizione fedele di un significato univoco dell’opera aldilà dei segni, naturali o culturali, che lo veicolano costituiscono tratti tipici dell’atteggiamento dei lettori medievali. A fronte di questi aspetti, tuttavia, è possibile sottolinearne altri eterodossi e perlopiù trascurati, quali la rilevanza attribuita all’interpretazione, prassi ineludibile e da disciplinare, al ruolo del lettore e alla sua fruizione attiva e produttiva dei testi. The aim of the work is to problematize some aspects generally considered representative of the relationship between medieval savants and the book - in its variations of Bible, Book of Nature and so-called auctoritates . The use, as tools, of newly developed concepts and observations of contemporary thinkers on this subject, is not aimed at updating this relationship, but rather at expanding the points of view on it and testing its ability to adduce original food for thought. The theoretical suggestions of Jacques Derrida, Michel Foucault and Roland Barthes are used here as examples of an interpretation that has historically made almost paradigmatic the way of reading of early medieval writers. However, some definitions of Scripture - the book by definition - proposed by them and the theory of its fourfold sense seem to blunt these drastic observations. Concepts such as Foucault’s "author-function" or Barthes’ "text" are used to consider in a different theoretical context the relation between late medieval thinkers and the so-called auctoritates . In ordinary vision the reverence for the divine or human author, the research and the revival of a true single meaning of his work beyond its natural or cultural signs are typical features of the attitude of medieval readers. In relation to these aspects, however, it is possible to highlight other heterodox and less considered ones, such as the importance given to the interpretation, inescapable practice that has to be regulated, to the reader’s role and to his active and productive use of texts.
