This article explores the common points and the differences between Hans Kelsen’s and Robert Alexy’s application theories. Although Kelsen subscribed to moral relativism and denied the idea of a practical reason, while Alexy criticised moral relativism and defended the idea of a communicative reason, it is argued that the two theories share important common features, such as denying that interpretation can point one single answer as the right one and acknowledging that interpretation is comprised by both knowledge and will. The (...) article acknowledges that there are differences between both theories, analyses whether these differences are qualitative or quantitative and, in the end, concludes that between the two theories there is not disruption, as one might believe, but rather continuity.

The traditional and majoritarian view about Kelsen's doctrine of the basic norm has affirmed that Kelsen had drastically changed its philosophical status in the early 1960s, when he allegedly began...

No mês de Novembro de 2017, em ocasião do Dia Mundial da Filosofia da UNESCO, a Cátedra UNESCO Archai, do Programa de Pós-Graduação em Metafísica da Universidade de Brasilia, organizou um hangout Unesco sobre o tema Filosofia, gênero e feminismo, do qual participaram diversxs colegas brasileirxs, especialistas do tema, acima assinadxs.

Neste artigo analisaremos como a filosofia de Charles Sanders Peirce influencia o pensamento de Karl-Otto Apel na elaboração da sua ética do discurso. Pretendemos mostrar que Apel compreende que Peirce elabora uma transformação da filosofia transcendental kantiana, substituindo o “eu penso” por um “eu argumento”, neste viés Peirce demonstrou a existência de um acordo mútuo intersubjetivo dentro da comunidade científica. Sendo que, este acordo é mediado pela linguagem, e se dá em função da garantia da verdade das proposições. Conclui-se que (...) Apel ver em Peirce a introdução de uma ética mínima que supera o solipsismo metódico, e se baseia na intersubjetividade, tornando possível um acordo mútuo, que mais tarde será a base para a fundamentação pragmático-transcendental da ética do discurso.

Este artigo tem por objetivo analisar o projeto arquitetônico de fundamentação da ética do discurso desenvolvido por Karl-Otto Apel, a partir da década de 70. Pretendemos mostrar que Apel, a partir da linguagem, buscará desenvolver uma ética da responsabilidade para a sociedade global. Neste sentido, a linguagem enquanto médium intransponível de toda reflexão teórica e prática fundamenta uma intersubjetividade, que torna possível uma ética do acordo mútuo. Esta ética buscará dar conta, não apenas do plano normativo, mas, levará em consideração, (...) também, o âmbito prático de fundamentação. (shrink)

This volume presents an extended version of the contributions presented at the workshop "Kant's Concept of Law" held at the 26th World Congress of the International Association for Philosophy of Law and Social Philosophy (IVR) in 2013. It handles issues of applied legal philosophy in Kant's Doctrine of Right such as ownership, the alleged right of necessity, the right of resistance and the right of revolution. With each of these applied issues, the focus lies, on the one hand, on the (...) relationship between the principles a priori of law and of the duties of rights, as well as their normative requirements - for instance, the duty of independence from the coercion by others - and, on the other hand, empirical situations and their pressing demands. Thus, this volume illustrates how Kant concretely conceives of the doctrine of "first metaphysical of the doctrine of right" as supplying "the immutable principles for any giving of positive law". Each essay of this volume not only undertakes a careful and original interpretation of Kant's theses, but also offers a critical assessment. (shrink)

IntroductionThere is a need to maintain rehabilitation activities and motivate movement and physical activity during quarantine in individuals with Cerebral Palsy.ObjectiveThis paper sets out to evaluate the feasibility and potential benefits of using computer serious game in a non-immersive virtual reality implemented and evaluated completely remotely in participants with CP for Home-Based Telerehabilitation during the quarantine period for COVID-19.MethodsUsing a cross-sectional design, a total of 44 individuals participated in this study between March and June 2020, 22 of which had CP (...) and 22 typically developing individuals, matched by age and sex to the individuals with CP. Participants practiced a coincident timing game1 and we measured movement performance and physical activity intensity using the rating of perceived exertion Borg scale.ResultsAll participants were able to engage with the VR therapy remotely, reported enjoying sessions, and improved performance in some practice moments. The most important result in this cross-sectional study was the significant increasing in rating of perceived exertion in both groups during practice and with CP presenting a higher rating of perceived exertion.ConclusionChildren with CP enjoyed participating, were able to perform at the same level as their peers on certain activities and increased both their performance and physical activity intensity when using the game, supporting the use of serious games for this group for home therapy and interactive games.Clinical Trials Registrationhttps://Clinicaltrials.gov, NCT04402034.

The study of anarchism as a philosophical, political, and social movement has burgeoned both in the academy and in the global activist community in recent years. Taking advantage of this boom in anarchist scholarship, Nathan J. Jun and Shane Wahl have compiled twenty-six cutting-edge essays on this timely topic in New Perspectives on Anarchism.

Este texto tem como finalidade abordar questões voltadas à construção da identidade étnico/racial da criança negra, levantando discussões sobre os contos de fadas, notadamente Branca de Neve e Bela Adormecida, e sua influência no processo de construção identitária, enquanto oferta de um único tipo de obra literária para as crianças. Partindo desse pressuposto, traçamos o seguinte objetivo: analisar a contribuição dos contos de fadas para a formação da identidade étnico/racial da criança negra, investigando dois contos de fadas mais populares e (...) que fortalecem uma concepção de estética que contribui para o fortalecimento do racismo e disseminação de práticas racista na sociedade e consequente baixa autoestima da criança negra. Sendo assim, a metodologia foi análise documental, com revisão das obras: Branca De Neve e a Bela Adormecida. Esta pesquisa visa fornecer instrumentos para aumentar as formas de discussões e debates sobre o assunto, que sirva como um suporte para professores desenvolverem novas concepções sobre ampliação das escolhas literárias e roda de conversas no meio de estudantes para que só aumentem as possibilidades de aprendizagem. Foram trazidos ao debate teóricos como: Gomes, Brandão, Freire Coelho, Munanga, dentre outros, a fim de embasar esta pesquisa. (shrink)

O presente artigo tem por objetivo apresentar as contribuições da estética da existência em Foucault para o âmbito da educação. Inicialmente será apresentado, em linhas gerais, os três domínios de sua produção teórica: Arqueologia do Saber, Genealogia do Poder e Estética da Existência. Posteriormente, será exposto mais profundamente a terceira fase de sua obra, destacando as ideias acerca do conceito do Cuidado de Si e a sua relação com o ambiente escolar e a formação docente. A estética da existência caracteriza-se (...) como o terceiro domínio foucaultiano e concerne na ideia da vida como obra de arte, onde por meio das práticas de si, cuidado de si, governo de si, _parrhesía_ e exame de consciência o sujeito torna-se capaz de estilizar sua existência, moldando sua vida e sendo artesão de si mesmo. Os apostes teóricos que fundamentam a pesquisa, além do Michel Foucault, são: Veiga-Neto (2016), Brandão (2011), Barcelos, Rabelo e Rodrigues (2009), entre outros autores. Esses correlacionam a obra do Filósofo Michel Foucault com a Educação. A partir da relação estabelecida entre a Estética da Existência e a Educação, percebeu-se que a escola têm sido, desde a sua fundação até os dias de hoje, um espaço que prioriza a disciplina e a normatização. Portanto, faz-se necessário introduzir nesse espaço saberes que possibilitem um novo modo de formar os sujeitos para que esses sejam conscientes e desfrutem da sua liberdade, que por muitas vezes lhes é retirada.

Phenomenal particularism is the view that particular external objects are sometimes part of the phenomenal character of perceptual experience. It is a central part of naïve realist or relational views of perception. We consider a series of recent objections to phenomenal particularism and argue that naïve realism has the resources to block them. In particular, we show that these objections rest on assumptions about the nature of phenomenal character that the naïve realist will reject, and that they ignore the full (...) resources that naïve realism has to offer in explaining phenomenal character.

For Kant, the human cognitive faculty has two sub-faculties: sensibility and the understanding. Each has pure forms which are necessary to us as humans: space and time for sensibility; the categories for the understanding. But Kant is careful to leave open the possibility of there being creatures like us, with both sensibility and understanding, who nevertheless have different pure forms of sensibility. They would be finite rational beings and discursive cognizers. But they would not be human. And this raises a (...) question about the pure forms of the understanding. Does Kant leave open the possibility of discursive cognizers who have different categories? Even if other discursive cognizers might not sense like us, must they at least think like us? We argue that textual and systematic considerations do not determine the answers to these questions and examine whether Kant thinks that the issue cannot be decided. Consideration of his wider views on the nature and limits of our knowledge of mind shows that Kant could indeed remain neutral on the issue but that the exact form his neutrality can take is subject to unexpected constraints. The result would be an important difference between what Kant says about discursive cognizers with other forms of sensibility and what he is in a position to say about discursive cognizers with other forms of understanding. Kantian humility here takes on a distinctive character. (shrink)

Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...) as a valid theorem in quantum theory. We then present what we take to be a better and more general gauge argument, based on Noether's second theorem in classical Lagrangian field theory, and argue that this provides a more appropriate framework for understanding how gauge symmetry helps to constrain the dynamics of physical theories.

The present paper is about the author’s current research on children’s education in urban contexts. It departs from the rising offer of programmes for school children in out-of-school contexts (e.g. museums, libraries, science centres). It asks what makes these practices educational (and not just interesting, entertaining and/or audience building). Based on Biesta ( 2006a , 2010 ) theory of education, the author frames and analyses the educational characteristics of, and possibilities of articulating, in and out-of-school educational practices. This paper aims (...) at understanding if the occasional outing from primary school premises promotes interruptions in the humanist foundations of school. In order to analyse relations between different institutions and professionals (to be) engaged in educational activities and programmes, Nóvoa ( 2002 , 2009 ) essays will be brought to the discussion, namely his conception of the ‘Public Space of Education’—as a space where culture, education, arts, sports and leisure are shared responsibilities, and where diverse institutions are networked aiming towards societal pluralism. I argue for the possibility of using cities’ public spaces as contexts with a worldly quality to complexify children’s education. Nevertheless, I draw attention to the unbearable educational lightness that these practices may carry if they do not go beyond the praise of chance; as well as to their unsustainable weight if they perpetually repeat school’s normal orders and add up rational discourses.

In a previous article on cosmological arguments, I have put forward a few examples of complete infinite and circular explanations, and argued that complete non-wellfounded explanations such as these might explain the present state of the world better than their well-founded theistic counterparts (Billon, 2021). Although my aim was broader, the examples I gave there implied merely causal explanations. In this article, I would like to do three things: • Specify some general informative conditions for complete and incomplete non-wellfounded causal (...) explanations that can be used to assess candidate explanations and to generate new examples of complete non-wellfounded explanations. • Show that these conditions, which concern chains of causal explanations, easily generalize to chains of metaphysical, grounding explanations and even to chains involving other “determination relations” such as supervenience. • Apply these general conditions to the recent debates against the existence of nonwellfounded chains of grounds and show, with a couple of precise examples, that the latter can be complete, and that just like in the case of causal explanations, non-wellfoundedness can in fact be an aset rather than a liability.

According to what we will call subjectivity theories of consciousness, there is a constitutive connection between phenomenal consciousness and subjectivity: there is something it is like for a subject to have mental state M only if M is characterized by a certain mine-ness or for-me-ness. Such theories appear to face certain psychopathological counterexamples: patients appear to report conscious experiences that lack this subjective element. A subsidiary goal of this chapter is to articulate with greater precision both subjectivity theories and the (...) psychopathological challenge they face. The chapter’s central goal is to present two new approaches to defending subjectivity theories in the face of this challenge. What distinguishes these two approaches is that they go to great lengths to interpret patients’ reports at face value – greater length, at any rate, than more widespread approaches in the extant literature.

Patients suffering from the Cotard syndrome can deny being alive, having guts, thinking or even existing. They can also complain that the world or time have ceased to exist. In this article, I argue that even though the leading neurocognitive accounts have difficulties meeting that task, we should, and we can, make sense of these bizarre delusions. To that effect, I draw on the close connection between the Cotard syndrome and a more common condition known as depersonalisation. Even though they (...) are not delusional, depersonalised patients seem to have experiences that are quite similar to those of Cotard patients. I argue that these experiences are essentially characterised by a lack of subjective character and of two other structural features of experience, which I call ‘the present character’ and ‘the actual character’. Cotard's nihilistic delusions simply consist in taking these anomalous experiences at face value. (shrink)

Depersonalization is a pathological condition consisting in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, his mind and even from himself. In this article, I argue that the study of depersonalization raises three challenges for recent theories of the sense of bodily ownership. These challenges—which I call the centrality challenge, the dissociation challenge and the grounding challenge— thwart most of these theories and suggest that the (...) sense of bodily ownership hinges on a phenomenal mark of mineness that can not be accounted for in terms of our sensory, interoceptive, agentive, cognitive or affective dispositions and that is psychologically primitive. In short: that mineness is first. (shrink)

Resumo Palavras-chave Keywords : Narrative production. Authorship. Language. Memory. Identity. : This article comprises a detailed report on a project of narrative production, which is being conducted, every semester, with students entering the Languages course, on the Portuguese Language subject.The project consists of a process of production, reading, and rewriting of small narratives, which, at the end of the term, are gathered and organized by each student in order to assemble their own book craftily. The proposal came forth as a (...) strategy to try to solve problems related to the little familiarity with writing and to the lack of authorship marks. The engagement in the production of contextualized and guided narratives for a determined purpose has disclosed, at the end of each semester, similar results: pleasure to write, read and expose the produced texts for group discussions; concern with the interlocutor; presence of authorship marks; perception of discursive qualities on the text itself and on the text of others; concern with the adequacy of the writing to linguistic conventions; confidence on the writing process; perception of oneself as part of a history and as a result of multiple intersubjectivities; praise of one’s own life history and of one’s ancestors. The project finds itself based on enunciation theories. : Produção de narrativa. Autoria. Linguagem. Memória. Identidade. : Este artigo constitui-se do relato de um projeto de produção de narrativa que vem sendo desenvolvido, semestralmente, com alunos ingressantes no curso de Letras, na disciplina de Língua Portuguesa. O projeto consiste em um processo de produção, leitura e reescritura de pequenas narrativas com as quais, ao fim do semestre, cada aluno organiza e confecciona artesanalmente o seu próprio livro. A proposta surgiu como estratégia para tentar solucionar problemas relacionados à pouca familiaridade com a escrita e à ausência de marcas de autoria. O enfoque na produção de narrativas contextualizadas e orientadas para um determinado fim tem revelado, no fim de cada semestre, resultados semelhantes: prazer de escrever, de ler e de submeter à discussão do grupo os textos produzidos; preocupação com o interlocutor; presença de marcas de autoria; percepção de qualidades discursivas no próprio texto e no texto do outro; preocupação com a adequação da escrita às convenções linguísticas; segurança em relação à escrita; percepção de si como parte de uma história e como fruto de intersubjetividades múltiplas; valorização da própria história de vida e da de seus antepassados. O trabalho encontra suporte em teorias da linguística da enunciação. (shrink)

Seven informants , aged between 32 and 42, who had experienced at least one career change in their lives were interviewed about the history of their career trajectories. The interviews were analyzed according to the systematic and systemic reflexivity proposed by the phenomenological tradition: description, reduction and interpretation. The findings point to the need for professional guidance practice giving attention not only to professional information but also to a reflection of individual and work-related values. This would help both young people (...) and adults to see their own objectives more clearly and to be capable of formulating their own career plans and following them through. (shrink)

Cet article propose un itinéraire de réflexion sur les fondements de l’éthique théologique en articulant trois contributions de Karl Barth à ce domaine : la définition de l’éthique comme l’impératif de l’indicatif qu’est la dogmatique, voire l’inséparabilité entre éthique et dogmatique qui place l’éthique à l’écoute de la révélation ; l’articulation d’un nexus christologique entre les catégories d’obéissance et de liberté comme « autodétermination déterminée » ; le débat sur l’Évangile et la Loi, comme révélation de l’histoire de la grâce (...) à partir de laquelle se déploie la grammaire d’une existence chrétienne. Cet itinéraire est entrecoupé par trois passages bibliques qui sont alignés sur les contributions de Barth : la vocation d’Abraham ; l’agonie de Jésus à Gethsémani ; la question posée à Jésus sur le bien qu’il faut faire pour entrer dans la vie éternelle. Nous suggérons que cet itinéraire biblique et barthien souligne qu’une éthique théologiquement construite conflue vers la christologie. (shrink)

In most western countries, there is a 'human organ shortage' with waiting lists for the performance of transplantation. In a recent report of the UNOS Ethics Committee it is stated that there are approximately 31,000 potential recipients on waiting lists, but only one fourth of potential donors give their specific consent. Xenotransplantation--defined as the transplantation of animal cells, tissues or organs into human beings--is associated with particular ethical dilemmas, namely the problems of efficiency and safety of this medical procedure. The (...) objective of this study is to analyse the ethical dilemmas in xenotransplantation with the background of a personal view of moral life. Also, xenotransplantation will be evaluated as far as the legal regulation of transplantation is concerned. In particular, we will consider patients rights in accordance with existing laws on organ and tissue transplantation, animal research and clinical trials. (shrink)

Insects reevaluated as archives foreground possible sites of multidisciplinary research, with multifaceted potential for the history of science.

In their target article, Kammerer and Frankish (K&F) wonder what forms introspection could take in non-human animals, enhanced humans, artificial intelligences, and aliens. In this short note, I focus on disordered or neurodiverse minds. More specifically, I assess a claim that has often been made more or less implicitly to the effect that, in virtue of their conditions, people with schizophrenia or depersonalization disorder have superior introspective abilities that allow them to discern some important but normally hidden characteristics of our (...) experiences — call this the superintrospectionitis thesis. In the course of my argumentation, I introduce distinctions and questions concerning the nature of the architecture and the function of introspection that might enrich K&F's framework. (shrink)

Computational reproducibility possesses its own dynamics and narratives of crisis. Alongside the difficulties of computing as an ubiquitous yet complex scientific activity, computational reproducibility suffers from a naive expectancy of total reproducibility and a moral imperative to embrace the principles of free software as a non-negotiable epistemic virtue. We argue that the epistemic issues at stake in actual practices of computational reproducibility are best unveiled by focusing on software as a pivotal concept, one that is surprisingly often overlooked in accounts (...) of reproducibility issues. Software is not only about designing and coding but also about maintaining, supporting, distributing, licensing, and governance; it is not only about developers but also about users. We focus on openness debates among computational chemists involved in molecular modeling software packages as empirical grounding for our argument. We then identify and analyse four epistemic characteristics as key to the role of software in computational reproducibility. (shrink)

PRINCÍPIO DA COMPLEMENTARIDADE RECURSAL APÓS DECISÃO DOS EMBARGOS DE DECLARAÇÃO: GARANTIA DO CONTRADITÓRIO EM OPOSIÇÃO À PRECLUSÃO CONSUMATIVA.

In this work, we propose a computational approach to the triadic model of Peircean semiosis (meaning processes). We investigate theoretical constraints about the feasibility of simulated semiosis. These constraints, which are basic requirements for the simulation of semiosis, refer to the synthesis of irreducible triadic relations (Sign–Object–Interpretant). We examine the internal organization of the triad S–O–I, that is, the relative position of its elements and how they relate to each other. We also suggest a multi-level approach based on self-organization principles. (...) In this context, semiosis is described as an emergent process. Nevertheless, the term ‘emergence’ is often used in a very informal way in the so called ‘emergent’ computation, without clear explanations and/or definitions. In this paper, we discuss in some detail the meaning of the theoretical terms ‘emergence’ and ‘emergent’, showing how such an analysis can lead to improvements of the algorithm proposed. (shrink)

Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist views cannot (...) account for the generality of visual experiences, and that the naïve realist explanation of particularity has unacceptable implications for self- knowledge: the knowledge we have of the character of our own experiences. We argue in this paper that neither claim is correct: naïve realism can explain the generality of experiences, and the naïve realist explanation of particularity raises no problems for our self-knowledge.

Organisations are increasingly transforming themselves to remain profitable and obtain sustainable competitive advantages. Business processes are as important as technology in promoting organisational transformation. Organisational transformation ultimately entails combining existing business components, whether or not with the same use and design, with new ones to generate novel products and services. For example, one particular type of organisation transformation is digital transformation. This notion, which covers even the subjective aspects of organisational transformation, is currently under intensive discussion and suffers from the (...) semantics terms fluctuation related to the notion of ‘organisational transformation’. We argue that this topic could strongly benefit from an ontological analysis and conceptual clarification of these notions. This paper contributes with an attempt in this direction by proposing a Core Ontology of Organisational Transformation (COOT). This ontology comprises concepts and relations central to creating a reference model representing the organisational transformation paradigm. COOT was applied in a real-world case study on a car rental company. (shrink)

Depersonalization consists in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, and his mind, and even from himself. Even though, when it was discovered at the end of the 19th century, this psychiatric condition was widely used to probe certain aspects of bodily awareness, and more specifically the sense of bodily ownership (SBO), it has been strangely neglected in contemporary debates. In this chapter, I argue (...) that because of three specific features, depersonalization raises some important challenges for current theories of the SBO. The first feature — call it “generality” — is that depersonalization does not only affect the sense of bodily ownership but also, typically, the sense of ``mental ownership’’ (SMO), the sense of agency or ``action ownership’’ (SOA), and the subject’s core sense of herself (CSS), that is, her awareness of herself as an I. The second feature is that except for the symptoms of depersonalization, depersonalized patients are hard to distinguish, psychologically, from normal subjects. This makes it hard to find psychological features that might explain their condition. The last feature, call it “fundamentality” is that the psychological features that do seem abnormal among depersonalized patients seem more likely to be explained by depersonalization than to explain it. These three features raise three challenges — the centrality challenge, the dissociation challenge, and the grounding challenge. Taken together, I will argue, these challenges suggest that the SBO depends on a form of phenomenal “mineness” that would mark my mental states as mine and that cannot be accounted for in sensorimotor, cognitive, or even affective terms. A phenomenal mineness that indeed seems to be psychologically primitive, and only accountable in neurophysiological terms. (shrink)

This paper investigates the implicative conditional, a connective intended to describe the logical behavior of an empirically defined class of natural language conditionals, also named implicative conditionals, which excludes concessive and some other conditionals. The implicative conditional strengthens the strict conditional with the possibility of the antecedent and of the contradictory of the consequent. $${p\Rightarrow q}$$ p ⇒ q is thus defined as $${\lnot } \Diamond {(p \wedge \lnot q) \wedge } \Diamond {p \wedge } \Diamond {\lnot q}$$ ¬ ◊ (...) ( p ∧ ¬ q ) ∧ ◊ p ∧ ◊ ¬ q. We explore the logical properties of this conditional in a reflexive normal Kripke semantics, provide an axiomatic system and prove it to be sound and complete for our semantics. The implicative conditional validates transitivity and contraposition, which we take to be integral parts of reasoning and communication. But it only validates restricted versions of strengthening the antecedent, right weakening, simplification, and rational monotonicity. Apparent counterexamples to some of these properties are explained as due to contextual factors. Finally, the implicative conditional avoids the paradoxes of material and strict implication, and validates some connexive principles such as Aristotle’s theses and weak Boethius’ thesis, as well as some highly entrenched principles of conditionals, such as conjunction of consequents, disjunction of antecedents, modus ponens, cautious monotonicity and cut.

According to David Chalmers, the virtual entities found in Virtual Reality (VR) and Augmented Reality (AR) environments instantiate virtual properties of a specific kind. It has recently been objected that such a view (i) can’t extend to all types of properties; (ii) leads to a proliferation of property-types; (iii) implausibly ascribes massive errors to VR and AR users; and (iv) faces an analogue of Jackson’s “many-property problem”. My first objective here is to show that advocates of virtual properties can deal (...) with each of these objections. The other goal of this paper is to examine the consequences of Chalmers’ theory in the particular case of AR. If we countenance virtual properties, AR highlights that non-virtual objects can possess both non-virtual and virtual properties. With AR, it also appears that a same non-virtual object can have different and even incompatible properties across augmented environments. Lastly, considering properties in light of AR highlights the risk of an “augmented solipsism”, and calls forth interesting questions about the persistence conditions of non-virtual objects in AR environments.

Using emotional film clips is one of the most popular and effective methods of emotion elicitation. The main goal of the present study was to develop and test the effectiveness of a new and comprehensive set of emotional film excerpts. Fifty film experts were asked to remember specific film scenes that elicited fear, anger, sadness, disgust, amusement, tenderness, as well as emotionally neutral scenes. For each emotion, the 10 most frequently mentioned scenes were selected and cut into film clips. Next, (...) 364 participants viewed the film clips in individual laboratory sessions and rated each film on multiple dimensions. Results showed that the film clips were effective with regard to several criteria such as emotional discreteness, arousal, positive and negative affect. Finally, ranking scores were computed for 24 classification criteria: Subjective arousal, positive and negative affect (derived from the PANAS; Watson & Tellegen, 1988), a positive and a negative affect scores derived from the Differential Emotions Scale (DES; Izard et al., 1974), six emotional discreteness scores (for anger, disgust, sadness, fear, amusement and tenderness), and 15 “mixed feelings” scores assessing the effectiveness of each film excerpt to produce blends of specific emotions. In addition, a number of emotionally neutral film clips were also validated. The database and editing instructions to construct the film clips have been made freely available in a website. (shrink)

According to a common philosophical intuition, the deep nature of things is hidden from us, and the world as we know it through perception and science is somehow shallow and lacking in reality. For all we knwo, the intuition goes, we could be living in a cave facing shadows, in a dream or even in a computer simulation, This “intuition of unreality” clashes with a strong, but perhaps more naive, intuition to the effect that the world as we know it (...) seems perfectly real. Shadows, dreams, or informational structures appear too unreal to be identical to the world as we know it! This clash between the two intuitions forms the basis of the "problem of reality." At the turn of the nineteenth century psychiatrists encountered patients they referred to as “metaphysician doubters” who constantly questioned the reality of the world. This essay draws on the study of these patients to reject, and indeed diagnose, the intuition of unreality and recent metaphysical doctrines drawing on it, such as structuralism, digitalism, and virtual realism.

Aurélio Agostinho, when he was consecrated bishop in Hippo, had contact with a community in a situation of extreme social inequality, and adding to his understanding of bidirectional love (to God and neighbor), translated into nonconformity with the suffering of others, in the function as a bishop he had the opportunity to fight with the weapons at his disposal for a less undignified life for the poorest. Therefore, the concept of poverty that appears between the lines of his texts and (...) sermons is translated as a lack of material resources that makes it impossible for people to get the basics for survival. Among the weapons used by the philosopher bishop is the exhortation in his sermons, which in addition to denouncing the intense inequality of society, pondered on ways to resolve this huge gap between rich and poor. Thus, in this article we will analyze Augustine's lucubrations in sermons: 345, 355, 60, 61, 161, 14, which critically reflect poverty and wealth. The aforementioned sermons stand out on the subject for their critical reflections, because, although they treat the rich and their accumulation of wealth very harshly, showing solidarity with the less favored, and at different times they also have a critical look at the poor they idealized as a dream., desire or life goal to possess riches.
