Logical omniscience states that the knowledge set of ordinary rational agents is closed for its logical consequences. Although epistemic logicians in general judge this principle unrealistic, there is no consensus on how it should be restrained. The challenge is conceptual: we must find adequate criteria for separating obvious logical consequences from non-obvious ones. Non-classical game-theoretic semantics has been employed in this discussion with relative success. On the one hand, with urn semantics [15], an expressive fragment of classical game semantics that (...) weakens the dependence relations between quantifiers occurring in a formula, we can formalize, for a broad array of examples, epistemic scenarios in which an individual ignores the validity of some first-order sentence. On the other hand, urn semantics offers a disproportionate restriction of logical omniscience. Therefore, an improvement of this system is needed to obtain a better solution of the problem. In this paper, I argue that our linguistic competence in using quantifiers requires a sort of basic hypothetical logical knowledge that can be formulated as follows: when inquiring after the truth-value of ∀xφ, an individual might be unaware of all substitutional instances this sentence accepts, but at least she must know that, if an element a is given, then ∀xφ holds only if φ is true. This thesis accepts game-theoretic formalization in terms of a refinement of urn semantics. I maintain that the system so obtained affords an improved solution of the logical omniscience problem. To do this, I characterize first-order theoremhood in US+. As a consequence of this result, we will see that the ideal reasoner depicted by US+ only knows the validity of first-order formulas whose Herbrand witnesses can be trivially found, a fact that provides strong evidence that our refinement of urn semantics captures a relevant sense of logical obviousness.

Resenha do novo livro de Israel Finkelstein, publicado em inglês em 2013. Israel Finkelstein apresenta nova visão acerca do reino do Norte Israel, apontando a compilação e redação final das narrativas bíblicas pelos judaítas, depois da queda do reino do Norte Israel. É uma bela obra que resume o desenvolvimento das pesquisas arqueológicas do autor.

In this paper, I analyse EE I 6, where Aristotle presented a famous methodological digression. Many interpreters have taken this chapter as advocating a dialectical procedure of enquiry. My claim is that Aristotle does not keep a dialectical attitude towards endoxa or phainomena in this chapter. In order to accomplish my goal, I shall show that EE I 6 does not provide enough evidence for the dialectical construal of it, and that this construal, in turn, hangs on some assumptions brought (...) out from other Aristotelian works (EN and Top.), which do not provide good evidence as well. By the analysis of these assumptions, I intend to show that Aristotle is not carrying out any sort of dialectic, especially dialectic conceived as conceptual analysis seeking the salvage of phainomena or endoxa.

The purpose of this paper is an attempt to delimitate what the dialectical syllogism looks like in Aristotle’s Topics. Aristotle never gave an example of a dialectical syllogism, but we have some clues spread over books I and VIII of the Topics which make it possible to understand at least what within a dialectical debate is a dialectical syllogism. The interpretation advanced here distinguishes the logical order of the dialectical argumentation from the order of the debate. This distinction enables us (...) to have a better understand of what is and how the dialectical syllogism is identified in the debate. In addition, we can solve some interpretative difficulties other interpretations could not solve, and have a more solid grasp of how endoxa are used in a dialectical debate. (shrink)

In this paper we study in details a system of two weakly coupled harmonic oscillators from the point of view of Bohm's interpretation of quantum mechanics. This system may be viewed as a simple model for the interaction between a photon and a photodetector. We obtain exact solutions for the general case. We then compute approximate solutions for the case where one oscillator is initially in its first excited state (a single photon) reaching the other oscillator in its ground state (...) (the photodetector). The approximate solutions represent the state of both oscillators after the interaction, which is not an eigenstate of the individual hamiltonians for each oscillator, and therefore the energies for each oscillator do not exist in the Copenhagen interpretation of Quantum Mechanics. We use the approximate solutions that we obtained to compute Bohmian trajectories and to study the energy transfer between the oscillators. We conclude that, even using the Bohmian view, the energy of each individual oscillator is not well defined, as the nonlocal quantum potential is not negligible even after the coupling is turned off.

O artigo "Educação moral: a busca da excelência a partir de virtudes aristotélicas e a formação do educador" coloca em relevo a necessidade do cultivo de virtudes para a construção da excelência moral do homem. Discutimos a importância da compreensão do termo filosófico. Os resultados esperados consistem na possibilidade do educador de conseguir compreender, dentre os valores clássicos, em específico, o da justiça e o da amizade, como sendo a base para a discussão da educação moral. Se a educação moral (...) exerce algum papel na formação da personalidade humana, então, é preciso examinar quais virtudes são efetivamente necessárias para o desenvolvimento do caráter do homem. A educação moral, tal como temos concebido, possibilita a construção da autonomia do educando para que ele se torne um cidadão emancipado, independente, crítico e, antes, autocrítico. Com efeito, o problema desta investigação consiste na pergunta: quais são os desafios para a formação do educador no processo de conquista da excelência a partir de virtudes aristotélicas em se tratando de educação moral? Nesse sentido, o objetivo principal deste trabalho é compreender a excelência humana a partir do desenvolvimento de virtudes aristotélicas, especialmente a justiça e aamizade, com vistas aos desafios que se colocam aos educadores. Do ponto de vista do método, o trabalho é realizado a partir de revisão bibliográfica e procura problematizar, conceituar e argumentar características típicas do método de forma mais rigorosa, virtudes fundamentais para a formação do caráter do homem.

O que se pretende neste artigo é mostrar antes de tudo que revoluçáo galilena é fruto de uma mudança de mentalidade, de visáo de mundo, decorrente da própria crise por que passava o paradigma aristotélico . Um bom exemplo desta mudança e das dificuldades de livrar-se dos quadros tradicionais do pensamento filosofico é o matematismo(universo de precisáo) e a crença galileana em orbitas circulares, respectivamente. Com efeito, como poderá Galileu ser um dos fundadores da fisica moderna, se esta é fundamentada (...) no principio de inércia e na preponderancia da reta em relaçáo ao circulo? A resposta é a presentada a partir da analise do racíonio de Galileu no tocante a ideia de movimento. (shrink)

Is an ethical leader an oxymoron? Society demands and expects greater accountability from organizational leaders. The literature on leadership, especially business leadership, has neglected ethical issues by focusing only on those approaches and strategies that emphasize self-centred, individualistic concerns. How ever, true and effective leadership is one in which the leader's behaviour and the exercise of the leadership influence process are consistent with ethical and moral values. The authors argue that our understanding of leadership is incomplete, if not deformed, if (...) it does not include the three critical dimensions of ethical leadership. (shrink)

This article discusses the importance of metaemotions (emotions about emotions), showing their undeniable existence and how they are a critical and essential part of emotion life. The article begins by placing reflexivity of emotions within the general reflexivity of human beings. Then, the article presents the literature on metaemotion, showing some of the problems that surround them, which ultimately will lead to ask if the concept of metaemotion is really necessary. The second part of the article argues for the usefulness (...) of the concept, pointing out its role in establishing distinctions among emotional states as well as further clarifying the nature of emotion, and concludes on pointing out some of the directions for future research on metaemotions.

As result of the ongoing doctoral research, this paper composes the Communication delivered at the First National Post-Graduate Meeting in Philosophy of the University of Brasilia. The thesis relates to the real political action arising from liberty and immanent power. Structured in two moments of the Gramscian thought, that is: a) the juvenile phase (1914-1919), correspondent to the initial period of political engagement towards adherence to the Turin labor movement; and b) the analysis of the 48th § of Volume 3 (...) Prison Notebooks (Q 3, 48, 197) about the real political action. The whole problematic of the research relies in the investigation about Gramscian philosophical demands of the real political action that distinguishes it from the utopian idealism. In this sense, which are Gramscian´s contributions towards the Philosophy of praxis? The research indicates that the praxis requires a critical consciousness – passed through intellectual action in the formation of the people –, since the historical conditions are already given.

Este livro é uma apresentação das teorias e sistemas da psicologia contemporânea articuladas numa visão de conjunto em que podem ser estabelecidas suas afinidades e incompatibilidades. O texto compõe-se de doze capítulos. O primeiro trata de como se formou o campo específico da psicologia. No segundo, mostra-se como este espaço foi ocupado por diferentes doutrinas cientificistas, românticas e pós-românticas. Os demais capítulos apresentam as matrizes do pensamento psicológico e as teorias de surgimento.

We defend J. Kim's principle of explanatory exclusion from a recent criticism advanced by A Marras. We show that the principle follows from a less controversial principle of causal exclusion together with the assumption that claims of explanation are factual. We resolve the tension produced by Marras' argument by drawing a distinction between causal and explanatory relevance. In cross-level explanations (mental-to-physical and physical-to-mental) the explanans property is not causally but explanatorily relevant to the explanandum. This calls for an account of (...) how explanatorily relevant properties are grounded in causally relevant properties which in turn ultimately depend on causally efficacious properties. A. (shrink)

Defende-se que a análise da produção do conhecimento orientada pela perspectiva da concepção materialista e dialética da história deve pautar-se: pela percepção da realidade como totalidade pré-existente e independente da sua fragmentação em disciplinas; pelo entendimento de que a produção do conhecimento expressa no plano das ideias o embate travado no âmbito das relações de produção, por forças que disputam o controle e a direção das forças produtivas. Defende-se que não é suficiente classificar a produção do conhecimento conforme as orientações (...) epistemológica mas necessário e urgente situar esta produção na realidade que a produz. (shrink)

A general consensus has been reached in health care organizations that the disclosure of medical errors can be a very powerful way to improve patients and physicians well-being and serves as a core component to high quality health care. This practice strongly encourages transparent communication with patients after medical errors or unanticipated outcomes. However, many countries, such as Brazil, do not have a culture of disclosing harmful errors to patients or standards emphasizing the importance of disclosing, taking responsibility, apologizing, and (...) discussing the prevention of recurrences. Medical error is not discussed or approached during medical school. The stigma of error has a strong connection with value judgments, and emotional support for physicians does not exist. This paper suggests that open communication with the patient is essential. Guidance about error disclosure from health care organizations would be helpful for quality and patient safety and for health care professionals in countries like Brazil. (shrink)

A introdução da filosofia do direito na educação busca ampliar a compreensão dos alunos sobre os fundamentos teóricos, éticos e políticos do direito. Ela visa desenvolver habilidades de pensamento crítico e promover uma consciência cívica e ética em relação ao sistema jurídico e seu papel na sociedade. Os instrumentos essenciais do estudo filosófico são assuntos muito frequentes e indispensáveis, como; o sentido da aparição humana, como a origem e exício, a alegria e tristeza, o certo e o errado, a felicidade (...) e a dor, o amor, a capacidade, entre outros, que iluminam a relação entre todas as pessoas na sociedade aprendizagem e coexistência. Ao adotar essas abordagens, as instituições de ensino têm a oportunidade de enriquecer a experiência educacional, estimulando o desenvolvimento de competências críticas, a habilidade para resolver desafios complexos e a capacidade de tomar decisões éticas. Portanto esse estudo tem como objetivo articular sobre a compreensão dos fundamentos teóricos, desenvolvimento do pensamento crítico, reflexão ética e moral e consciência dos direitos e responsabilidades na educação de maneira comum.

This paper follows a Deweyan suggestion and proposes a structure for emotional activity – pattern of sentiment –as a way to grasp emotional experience in its live occurrence by building upon Dewey’s crucial notion of situation. The first part outlines Dewey’s criticisms of James’s idea of emotion, and verifies the ways in which the recent developments of neuroscience overcome Dewey’s criticisms of James. Given that Dewey’s work is a propitious ground for continuing to renew the discourse about the activities of (...) mind (Mendonça 2003), the second part of the paper outlines a pattern for emotional activity, setting up the first steps for a situational approach of Deweyan inspiration to the nature of emotion. I conclude by pointing out how such a pattern may be a unifying tool for the different emotion theories briefly describing some of the rich directions it provides for future research on philosophy of emotion.

The paper aims to better identify the relationship between moods and emotions showing their link to the overall environment. Adopting a Situated Approach to Emotions, 209–227, 2012; Stephan Emotion Review, 4, 157–162, 2012; Stephen et al. Philosophical Psychology, 27, 65–81 2014) enables showing that the link to emotions to the environment is best understood using the term situation, while moods’ link to the environment is best captured by the notion of context. Exploring the difference points out that what is selected (...) as the situation versus the context in a given environment may explain the relationship between emotions and moods, and clarify why, for instance, certain emotions can alter a mood while others do not. The paper begins putting forward the general take on emotions from a Situated Approach to Emotions in line with contemporary discussions of the Situated Approach to Mind. Then, following John Dewey’s conception of situation, the paper distinguishes situation from context, and reviews the hypothesis of equating them with emotions and moods respectively. The analysis is then connected to previous research done on the difference between emotions and moods and, given the insightful outcomes of connecting moods and emotions to other theoretical aspects of the mind, it shows how the link to the environment is a crucial trait to understand emotions and moods dynamics.

The article explores how a new dimension of emotion – depth – is crucially important for a better understanding of emotion and its connection to rationality. It begins by identifying that depth is trapped in a circularity in which deep emotions are important because they refer to deep and important aspects of people’s lives. Following Danto’s discussion of deep interpretation (1981), it suggests that it is the contrast between deep and superficial that grants emotional perspective and the ability to identify (...) levels of emotional depth. After arguing that the emotional perspective is grasped by the narrative structure of emotion, it raises several objections that provide the ground to establish a difference between deep and profound. Then the paper concludes that the meaning of emotional depth is only fully understood in the ongoing contrast with the superficial described before, and states how further research on depth of emotion may provide the key to understanding the ambivalent status of emotions regarding their link to rationality.

The chapter shows how the recognition of reflexivity of emotions is crucial for understanding the role of emotions in reasoning because it highlights the regulatory role of emotion in emotional experience. The chapter begins by showing that to attain a conception of rationality that incorporates feelings, emotions, and sentiments as parts of the reasoning processes requires capturing the emotional landscape in all its complexity, and that integrating the role of meta-emotions is a contribution in that direction. Then introducing the notion (...) of meta-emotions and showing how emotional reflexivity modifies the nature of our emotional world, it is shown how emotions also have a regulatory mechanism that can either be maladaptive or at the center of emotional health. In addition, because meta-emotions provide a test for the more general assumptions of theories of emotions, the chapter ends by showing how adopting a Situated Approach to Emotions is well-suited for explaining the refinement and complexity of emotion regulation. The final reflection of the chapter explains why adopting such theoretical frame of work makes it possible to use the term situation in a technical manner, which then reveals that emotions sometimes are described as causes while other times as reasons in connection to their regulative mechanisms.

The thesis of our commentary is that the framework used to address what are taken by Carey to be the open issues is highly problematic. The presumed necessity of an innate stock of representational primitives fails to account for the emergence of representation out of a nonrepresentational base. This failure manifests itself in problematic ways throughout Carey's book.

This article seeks to present the foundations in Foucault’s thought that led him to elaborate the concept of archeology and, in addition, try to recognize its limits. To achieve this, we present his main theoretical dialogues at the beginning of his investigations and the reasons that made necessary to reframe that concept later. Among the conclusions of this study, we suggest that the allegorical conception of language, that was sustained over the period, is formally similar to the structure of metaphysical (...) thought and, as such, is abandoned by Foucault as an attempt to create an original philosophical reflection.

resumo: Este trabalho investiga os laços entre a técnica, a metafísica e o totalitarismo, com base nos pensamentos de Heidegger e Arendt. Além disso, propõe que tais análises sugerem que a filosofia e a história pertencem a um enredo trágico fundamental. Para tanto, de início pesquisamos em que medida o ambivalente sentido de esgotamento e salvação, presente em diversas abordagens da técnica, implica a produção de prognósticos e uma reflexão teleológica. Investigamos se estes são elementos que, no século XX, serviram (...) de artifício para a legitimação da barbárie em movimentos totalitários e se permanecem necessariamente intrínsecos a toda visão da técnica. A abordagem de Heidegger, em alternativa, volta-se às origens da metafísica, onde residem as decisões que teriam culminado na técnica moderna, e onde presumimos estar enraizada esta estrutura trágica. a bstract: This study investigates the links between art, metaphysics and totalitarianism, based on the thoughts of Heidegger and Arendt. It also proposes that such analyses suggest that philosophy and history belong to a fundamental tragic plot. To do so, we start researching how the ambivalent sense of exhaustion and salvation, present in many approaches of technique, involves the production of prognoses and teleological reflection. We investigate if these are elements which, in the twentieth century, served as a device for legitimizing barbarity in totalitarian movements and if it remains necessarily intrinsic to every view of technique. Heidegger's approach, instead, turns to the origins of metaphysics, where the decisions that would have culminated in modern technique lie, and where we presume this tragic structure is rooted.

Este trabalho investiga a presença da figura de Zumbi dos Palmares no conto “A cabeça de Zumbi”, de Alberto Mussa, buscando tanto compreender aspectos históricos e culturais nele presentes como explorar a associação entre a figura mítico-histórica de Zumbi e a do orixá Exu. Inicialmente, para situar e dimensionar a importância do herói de Palmares para a história do negro no Brasil e dimensionar a questão de nossa formação identitária, utilizamos pensamentos de Sérgio Buarque de Holanda, Gilberto Freyre e Stuart (...) Hall, entre outros. Em seguida, enfocamos o conto e a relação entre Zumbi e Exu, feita por Conceição Evaristo na apresentação do livro, aprofundando-a a partir de informações colhidas nas obras de Reginaldo Prandi, Roger Bastide e Vagner Gonçalves da Silva e de observações críticas feitas por Moema Augel.

Reasonableness is a core normative concept in Philosophy for Children (P4C), an inquiry model of education that bridges reasoning, feeling and acting within a community. The concept of reasonableness dates back to Aristotle’s ethical notion of phronesis (1141b), and extends to logical (Gewirth 1983), social and political concerns of major contemporary thinkers (Rawls 2001; Rorty 2001). The development of the concept of reasonableness in P4C was part of the reconceptualization of rationality toward the end of the twentieth century, since Lipman (...) and Sharp were among those thinkers who elucidated and advocated the social conception of rationality offered by the pragmatists. Accordingly, in P4C the conception of reasonableness was highlighted as a cornerstone for the understanding of the notion of a community of inquiry (Splitter & Sharp 1995:6; Lipman 2003:22).

There is a broad debate in contemporary philosophy of logic on the informativeness of proofs. In this context, informative proofs are demonstrations whose premises do not include the content of the conclusion. D’Agostino and Floridi (Synthese 167(2):271–315, 2009) claimed that proofs are informative if they use _virtual information_. In their terminology, this is the data carried by _dischargeable hypotheses_, assumptions entertained during proof and eliminated before concluding. Although these authors capture several cases of informative demonstrations, they do not explain the (...) nature of virtual information. Why does the use of dischargeable hypotheses increase the informativeness of a demonstration? Following a Kantian inspiration, D’Agostino and Floridi claim that virtual information adds a synthetic feature to our proofs. However, this appeal to Kantianism is misleading: for Kant, mathematics is synthetic because it requires the construction of concepts in pure intuition. On the other hand, the entertainment of provisional hypotheses does not seem to involve the construction of figures in (transcendental) imagination. Exploring a _dialogical_ characterization of logic, I suggest that virtual information results from the dynamics between a reasoner and her audience. When a reasoner provisionally assumes _P_, she enacts potential interlocutors who commit to _P_. Thus, “virtual information” denotes the content of some assumptions of the possible audience of a demonstration. This process of departing from one’s original premises to embrace the suppositions of other people is informative, but it is not synthetic: in this way, the reasoner does not entertain intuitions but only needs to reason through the conceptual content of other people’s premises.

Nesse artigo, eu procuro mostrar que a leitura tradicional que atribui um procedimento dialético à abordagem aristotélica da acrasia, em Ética Nicomaquéia VII 1-3 provoca um sério problema interpretativo ao tentar compatibilizar a posição socrática acerca da acrasia e os phanomena. Primeiramente, tento mostrar, baseando-me numa análise de Tópicos I 1-2, que o procedimento metodológico, em EN VII 1 1145b2-7, não se caracteriza como dialético. Em segundo lugar, proponho uma leitura em que Aristóteles, passo a passo refuta a tese socrática (...) que nega a existência da acrasia, uma vez que esse tese não é contada entre os phainomena que se quer preservar.

This paper testifies the crucial importance of Philosophy for Children for Emotional Growth. It begins by establishing the open ended character of emotional processes, showing how feminist philosophers have criticized the fixed conception of negative valence of certain emotions, and how, ultimately, the normative structure of emotions is open to modification. Then, it shows how talking about emotional processes and emotional situations can foster emotional growth once we understand that the acquisition of language and emotional vocabulary is one way to (...) best capture the openended character of emotions. Finally, attention is turned to Philosophy for Children. Taking as an illustration the emotion of hope and its importance to inquiry, the paper concludes by examining in what way P4C both benefits and reinforces the previous insights about emotion theory.

O presente artigo tem o objetivo de discutir os regimes socioeconômicos que permitem a realização da justiça como equidade, focando em especial nos dois regimes apontados por Rawls como capazes de constituir uma sociedade bem ordenada, a democracia de cidadãos proprietários (property-owning democracy ou POD) de um lado e o socialismo liberal do outro. Para tanto, em um primeiro momento serão considerados os argumentos de Rawls a respeito dos regimes socioeconômicos dentro da Uma teoria da justiça. Em seguida, com base (...) em Justiça como equidade: uma reafirmação, serão discutidos os argumentos em favor da POD e do socialismo liberal e contra as outras três opções: capitalismo de laissez-faire, socialismo de Estado dirigido por um partido único e o Estado de bem-estar social. Em seguida, serão considerados os argumentos a favor da POD ou do socialismo liberal, procurando em grande medida traçar quais são as distinções entre ambos os regimes, a partir dos autores que buscam ir além de Rawls. Ao final, conclui-se que nos limites de uma teoria da justiça Rawls está correto ao não definir quem é o regime vencedor, a POD ou o socialismo liberal, mas no avanço atual do capitalismo liberal e no seu movimento de distanciamento das democracias liberais mostra-se necessário discutir qual é o regime mais adequado a partir das bases fornecidas pela justiça como equidade.

Education aims at the integral development of the person. However, there are few proposals that conceptualize ways to implement this desideratum. In the Portuguese context, we had the paradigmatic case of the Manuel Ferreira Patrício Cultural School. MFP differentiates itself by advocating for integral education that establishes an essential connection between the teaching, extra-lecture, interactive and ecological components of the school, highlighting the multidimensionalities of education: personality, culture, methodologies, curriculum, resources, educators, and pedagogical organization.
