O presente artigo tem por finalidade avaliar o problema intuicionista com as provas não construtivas na matemática. Para esta posição construtivista o princípio do terceiro excluído, da lógica clássica, não deve operar sobre demonstrações matemáticas. As provas não construtivas não são aceitas, sendo as provas construtivas as únicas com caráter positivo. Após uma breve introdução ao intuicionismo e seu idealizador, o artigo abordará a relação entre o princípio do terceiro excluído e as provas na matemática, para assim falar sobre o (...) problema das provas não construtivas e da consequência em não aceitá-las. Ao tomar a matemática unicamente como um empreendimento de construção mental, o intuicionismo quebra com o realismo platônico dominante e estabelece um debate frutífero sobre os fundamentos da matemática.

RESUMO A série Black Mirror, transmitida entre 2011 e 2023 pela Netflix, tornou-se um fenômeno de mídia e seus episódios mostraram formas de interação homem-máquina (terminologia também referida como humano-computador). O nome da série se refere ao fato de que, quando uma tela é desligada, ela se torna um espelho negro que reflete a imagem do usuário. Este artigo1 tem como objetivo analisar os efeitos da interação homem-máquina nas organizações produtivas apresentadas em Black Mirror. Esta pesquisa utilizou a análise do (...) discurso, principalmente a partir das contribuições de Mikhail Bakhtin. O método consistiu em três etapas que contaram com a colaboração de estudantes de graduação e pós-graduação em Engenharia de Produção, integrando ensino e pesquisa e desenvolvendo o senso crítico dos pesquisadores-iniciantes. Os resultados indicam que, nas organizações apresentadas na série Black Mirror, há uma transição do conceito de fatores humanos para fatores ciborgues, bem como o uso da interação homem-máquina para promover o controle social.

Properly speaking, the corporation, considered as an entity distinct from its members, cannot be morally responsible for wrongful corporate acts. Setting aside (in this abstract) acts brought about through negligence or omissions, we may say that moral responsibility for an act attaches to that agent (or agents) in whom the act "originates" in this sense: (1) the agent formed the (mental) intention or plan to bring about that act (possibly with the help of others) and (2) the act was intentionally (...) brought about through bodily movements over which that agent had direct control (i.e. the kind of direct mental control that I have over the body I refer to as "my" body) and through which the agent carried out his (mental) intention or plan. Corporate acts do not thus originate in some corporate entity distinct from its members because the corporation has neither a mind to form intentions nor a body it directly controls: it lacks the proper mind/body unity. Instead, corporate acts originate in individual autonomous human beings who make up the corporation and who intentionally bring about corporate acts through their own bodily movements. Such human individuals, and not "the corporation," are morally responsible for corporate acts. Moreover, to say that an entity is "morally responsible" for a wrongful act is to say that the entity is liable to blame and punishment. But it is not possible to impose blame and punishment on a corporation without inflicting it on corporate members. Thus, to say that a corporation (as an entity distinct from its members) is "morally responsible" for a wrongful corporate act is to imply that a (possibly innocent) corporate member legitimately may be punished for something for which another entity was morally responsible. This violates the moral principles that underlie blame and punishment. To hold that the corporation can be morally responsible for its acts is to adopt a dangerous organicism. (shrink)

I address three topics. First, I argue that the issue of corporate moral responsibility is an important one for business ethics.Second, I examine a core argument for the claim that the corporate organization is a separate moral agent and show it is based on anunnoticed but elementary mistake deriving from the fallacy of division. Third, I examine the assumptions collectivists make about whatit means to say that organizations act and that they act intentionally and show that these assumptions are mistaken (...) in their failure to understand the nature of intentional causality and of “as-if” intentionality. In exposing these mistakes I set out my own view in the form oftwo theses, the first of which states that individual members of an organization are always causally responsible for any corporate act,and the second of which states that attributions of intentions to corporations are always either descriptive or prescriptive attributionsof “as if” intentionality.

O presente artigo busca analisar os processos, fluxos e refluxos, de desterritorialização e territorialização, no contexto da diáspora negra no Brasil. Através dos conceitos de quilombismo e comunidade, examinará as comunidades virtuais “Ponte para Pretx” e “Intelectuais Negras: escrita de si mesma” localizadas no Facebook, articulando ponderações e reflexões em torno dos processos de empoderamento negro, ativismo, solidariedade e resistência negra, nucleados na ideia de comunidade virtual. Desta maneira, através dos pressupostos da hermenêutica histórica, a pesquisa demonstrará de que maneira (...) as comunidades virtuais fortalecem a cultura negra, segundo a potência de construir territórios de sentido às populações negras brasileiras em torno de arranjos e organizações sociais e culturais.

The author sets out a realist defense of the claim that in the absence of an international enforcement agency, multinational corporations operating in a competitive international environment cannot be said to have a moral obligation to contribute to the international common good, provided that interactions are nonrepetitive and provided effective signals of agent reliability are not possible. Examples of international common goods that meet these conditions are support of the global ozone layer and avoidance of the global greenhouse effect. Pointing (...) out that the conclusion that multinationals have no moral obligations in these areas is deplorable, the author urges the establishment of an international enforcement agency. (shrink)

Many biologists, especially in ecology and evolution, analyze their data by estimating fits to a set of candidate models and selecting the best model according to the Akaike Information Criterion (AIC) or the Bayesian Information Criteria (BIC). When the candidate models represent alternative hypotheses, biologists may want to limit the chance of a false positive to a specified level. Existing model selection methodology, however, allows for only indirect control over error rates by setting a threshold for the difference in AIC (...) scores. We present a novel theoretical framework for parametric Neyman-Pearson (NP) model selection using information criteria that does not require a pre-data null and applies to three or more non-nested models simultaneously. We apply the theoretical framework to the Error Control for Information Criteria (ECIC) procedure introduced by Cullan et al. (J Appl Stat 47: 2565–2581, 2019), and we show it shares many of the desirable properties of AIC-type methods, including false positive and negative rates that converge to zero asymptotically. We discuss implications for the compatibility of evidentialist and severity-based approach to evidence in philosophy of science. (shrink)

I argue that Plato was right in claiming that justice is more profitable, more rational, and more intrinsically valuable than injustice, and that this is particularly true for business organizations. The research on prisoners’ dilemmas and social dilemmas shows that ethical behavior is more profitable and more rational than unethical behavior in terms of both the negative sanctions on unethical behavior when interactions with stakeholders are iterated, and the positive rewards of habitually ethical behavior when stakeholders can identify those who (...) are predisposed to be ethical. In addition, the psychological research on justice shows that justice is intrinsically valued, both from an outcome and from a process perspective, and so crucial for business organizations, particularly in terms of organizational effectiveness.

Background: Despite the progress made in recent decades on the phenomenon of futility in adult intensive care, recognizing it during clinical care practice remains a complex and sensitive process, during which questions are often raised for which concrete answers are difficult to find. Aims: To analyze the frequency with which futile nursing interventions are implemented in critically ill patients admitted to adult intensive care in specific situations and how often futile autonomous and interdependent nursing interventions are implemented in the same (...) population, as perceived by adult intensive care nurses. Research design: Cross-sectional, quantitative, and descriptive study, which employed a questionnaire constructed specifically for this research to assess the perception of therapeutic futility in nursing in adult intensive care. Following an evaluation of the psychometric properties, the questionnaire was made available in an electronic format on the EUSurvey platform between August and October 2024. The data was analyzed between November 2023 and March 2024 using the statistical software packages SPSS and R. Participants and research context: A simple random sample of nurses working in level II and level III intensive care units in Portugal. Ethical considerations: Research ethical approvals were obtained, and the participants provided informed consent. Findings/results: Four hundred and fourteen valid questionnaires were obtained. The results allow the identification of thirty-three statistically significant associations, the inference of intervals for the mean and median for the perception of futility of nursing interventions with a 95% confidence interval, and enable the hierarchization of nursing interventions implemented in critically ill patients admitted to adult intensive care units according to the nurses’ perception of their futility. Conclusion: There is a balance in nurses' perception of the futility of their interventions in the specific situations analyzed. There is statistically significant evidence that interdependent nursing interventions are, in general, more frequently perceived as futile when compared to autonomous nursing interventions. (shrink)

La perspectiva historiográfica ofrecida por la teoría de las consecuencias involuntarias puede ser reconceptualizada en una concepción del mercado que explique su funcionamiento como una continua interrelación entre individuos que desconocen las consecuencias colectivas de los cursos de acción que emprenden.Asimismo, podrían distinguirse dos versiones de dicha teoria; de un lado, Ia versión débil, que se correspondería con el concepto de mercado de Hayek, y, deI otro, Ia versión fuerte. EI objetivo de este artículo es proponer el concepto al que (...) hemos denominado el principio de ignorancia, que seria una concepción acerca deI desenvolvimiento deI mercado acorde con los rasgos propios de Ia versión fuerte de Ia teoría de las consecuencias involuntarias.The historiographical perspective of the theory of unintended consequences can be reconceptualized into a conception of the market which explains its operation as a continuous interaction among individuals that do not know the collective consequences of their behaviours.Also, two versions of this theory might be distinguished, the weak version, which corresponds to Hayek’s concept of market, and the strong version. The aim of this paper is to propose the concept that we have termed as ignorance principIe, which is a conception of the operation of the market that fits to the characteristics of the strong version of the theory of unintended consequences.

ABSTRACT In this text, we build dialogues between Mikhail Bakhtin’s moral philosophy and Hans Kelsen’s legal theory, analyzing the notions of ought to be, science, and being. The goals are to shed light on Bakhtin’s (1999) legal foundation, from the perspective of moral philosophy as philosophia prima, which encompasses the philosophy of religion and the philosophy of law (Bakhtin, 1999; Simões, 2024); and to point out ethical considerations for the sciences, particularly for Law and Linguistics. The research is bibliographical, and (...) the corpus consists, centrally, of the works Toward a Philosophy of the Act (Bakhtin, 1993) and General Theory of Law and State (Kelsen, 1949). Our conclusions point to Bakhtin’s (1999) contributions, which appear to be authoritative for a perspective on the ought to be in the world of life; and for the debate on ethics in the sciences (Kelsen, 1949; Rajagopalan, 2011), particularly around the scientist’s relationship with the ought to be (Bakhtin, 1999).

Según Williamson, saber y creer son estados mentales, pero creer algo verdadero y creer justificadamente algo verdadero no lo son. Ese tratamiento discriminatorio es relevante para la epistemología de Williamson. Su principal tesis epistemológica negativa y su principal tesis epistemológica positiva están en peligro si su teoría metafísica sobre lo mental es incorrecta. Presento aquí un problema para dicha teoría: impone limitaciones implausibles a los posibles usos de conceptos y expresiones lingüísticas. Describiré algunas opciones que tendría Williamson para evitar el (...) problema; pero sostendré que acarrean cierta dosis de arbitrariedad. (shrink)

Commercial genetic testing offered over the internet, known as direct-to-consumer genetic testing (DTC GT), currently is under ethical attack. A common critique aims at the limited validation of the tests as well as the risk of psycho-social stress or adaption of incorrect behavior by users triggered by misleading health information. Here, we examine in detail the specific role of advertising communication of DTC GT companies from a medical ethical perspective. Our argumentative analysis departs from the starting point that DTC GT (...) operates at the intersection of two different contexts: medicine on the one hand and the market on the other. Both fields differ strongly with regard to their standards of communication practices and the underlying normative assumptions regarding autonomy and responsibility. Following a short review of the ethical contexts of medical and commercial communication, we provide case examples for persuasive messages of DTC GT websites and briefly analyze their design with a multi-modal approach to illustrate some of their problematic implications. We observe three main aspects in DTC GT advertising communication: (1) the use of material suggesting medical professional legitimacy as a trust-establishing tool, (2) the suggestion of empowerment as a benefit of using DTC GT services and (3) the narrative of responsibility as a persuasive appeal to a moral self-conception. While strengthening and respecting the autonomy of a patient is the focus in medical communication, specifically genetic counselling, persuasive communication is the normal mode in marketing of consumer goods, presuming an autonomous, rational, independent consumer. This creates tension in the context of DTC GT regarding the expectation and normative assessment of communication strategies. Our analysis can even the ground for a better understanding of ethical problems associated with intersections of medical and commercial communication and point to perspectives of analysis of DTC GT advertising.

O presente trabalho realiza uma exposição do pensamento de Robert Alexy no que concerne às relações entre direito e moral, que pode ser entendido como uma tentativa de superação da antiga querela entre juspositivismo e jusnaturalismo. O autor desenvolve, então, um sistemaque permite apreciar as normas jurídicas de acordo com sua qualidade moral, privando de juridicidade aquelas consideradas demasiadamente injustas e corrigindo aquelas consideradassanáveis.

RÉSUMÉ : Les attitudes de se sont généralement considérées comme constituant une classe particulière d’attitudes de re. Cet article propose une analyse différente, qui s’appuie sur la notion d’attitude de objecto et qui évite un engagement ontologique envers le sujet. La proposition élabore l’idée de Hintikka d’une logique épistémique dite de seconde génération, qui introduit un marqueur syntaxique permettant d’exprimer des relations d’indépendance entre certaines constantes logiques. De cette sémantique résulte une conception du Moi, dénotation de «je», comme un objet (...) simplement intentionnel. ABSTRACT: De se attitudes are generally regarded as being a proper part of de re attitudes. In this paper an alternative analysis that avoids ontological commitment to the self is proposed, based on the notion of de objecto attitudes. This proposal develops an idea from Hintikka’s second generation epistemic logic, which introduces a syntactic marker expressing independence relations between certain logical constants. According to this semantic account, the Self, as the denotation of ‘I’, is conceived of as a mere intentional object. (shrink)

En ces temps d’avenir perdu, les sociétés sont des sociétés spéculatives, qu’elles le veuillent ou non. Alors que la crise financière de 2007–2008 s’est transformée en une myriade de crises politiques dans les années qui ont suivies. En effet, l’esprit d’un âge néo-biedermeierien et les programmes politiques axés sur la stabilité sont devenus le modus operandi de l’Occident dans les contextes économiques et bien au-delà. Le désenchantement du néolibéralisme et son eschatologie politique dans un large éventail de domaines socioculturels perdurent (...) des deux côtés de l’Atlantique, tout autant que l’aporie des sociétés qui tentent de sauver le statu quo même si celui-ci avait perdu son chemin. En conséquence, les sociétés actuelles seraient, même sans le désirer, des sociétés spéculatives. Des éclaircissements sur la notion même de spéculation apparaissent alors nécessaires. Cet article vise à offrir ces éclaircissements. Pour cela, cet article s’appuie sur le cadre réglementaire d’après-crise de Bâle III. Cette analyse philosophique est d’autant plus éclairante si le « désarmement de la politique » (Habermas 2018, ma traduction) au nom de politiques prétendument inévitables, à vocation sécuritaire et stable, peut constituer l’objet de critique. Cet article est, par conséquent, une esquisse philosophique. Ce qui suit est une série de réflexions sur le concept de spéculation au-delà des frontières de la compréhension financière ou économique actuelle et, enfin, de minuscules manifestes sur la façon dont les études philosophiques et autres pourraient mobiliser et affiner ce concept. Tout d’abord cet article offre une histoire conceptuelle de la notion de spéculation (section deux). Dans un deuxième temps, les effets instables de l’aporie de stabilité concernant des régularisations financières sont analysés (section trois). Enfin, les bases pour un renouveau du concept de spéculation, utile pour la philosophie et qui maîtrise les apories des sociétés spéculatives, sont développées (section quatre). Si la philosophie ne peut prévenir la pensée d’être parfois large et incertaine, la philosophie peut sans doute être appréhendée comme un « hybride onto-épistémique-éthique », en recourant à la notion de spéculation. C’est ce que cet article suggère : offrir un langage qui pourrait permettre de penser la « spécularisation » des mondes sociaux en ce début du xxi e siècle. C’est à dire, le passage de la politique des classes à la politique identitaire (représentant les cultures plutôt que les classes), du capitalisme industriel à la politique culturelle (vendre des valeurs au détriment des fonctions) et des acteurs rationalisés au conservateur (choisir entre des identités à la place des préférences).

O jornal Tribuna Criciumense foi o único impresso publicado na cidade de Criciúma no período deste escrito. Fundado em 1955, ele passou por três fases. Na primeira, produziu um discurso anticomunista, mas de maneira um pouco tímida. Na segunda fase, com curta duração, o impresso passou a valorizar a ideologia comunista e, ao mesmo tempo, a defesa do presidente João Goulart. A última fase foi marcada por ataques violentos contra o comunismo, em defesa do golpe civil-militar e da ditadura implantada. (...) Analisar essas fases e como os discursos anticomunista e pró-comunismo reverberaram no jornal se configura no objetivo deste escrito. (shrink)

Autonomous artificial intelligence (AI) systems can lead to unpredictable behavior causing loss or damage to individuals. Intricate questions must be resolved to establish how courts determine liability. Until recently, understanding the inner workings of “black boxes” has been exceedingly difficult; however, the use of Explainable Artificial Intelligence (XAI) would help simplify the complex problems that can occur with autonomous AI systems. In this context, this article seeks to provide technical explanations that can be given by XAI, and to show how (...) suitable explanations for liability can be reached in court. It provides an analysis of whether existing liability frameworks, in both civil and common law tort systems, with the support of XAI, can address legal concerns related to AI. Lastly, it claims their further development and adoption should allow AI liability cases to be decided under current legal and regulatory rules until new liability regimes for AI are enacted.

Tanto la Fórmula Barcan como la postulación de possibilia contradicen los juicios intuitivos preteóricos de la mayoría de los sujetos, favorables al actualismo sobre la naturaleza de los mundos posibles. En este artículo discuto y rechazo dos argumentos que pretenderían contrarrestar tales juicios, y que conciben erróneamente la relación entre la semántica de mundos posibles y nuestros lenguajes naturales modales. El argumento más importante asume que el dominio de todas las entidades es idéntico al dominio de @. Desarrollo una interpretación (...) de la SMP conforme a la cual esa tesis no está suficientemente justificada. /// Barcan Formula and the postulation of possibilia contradict the pretheoretical intuitive judgments of most people, which favour actualism about possible worlds. In this paper I discuss and reject two arguments against such judgments, both of which conceive wrongly the relation between possible worlds semantics and modal natural languages. The more important argument assumes that the domain of the actual world is identical to the domain of @. I develop an interpretation of PWS which elucidates why that thesis is unwarranted. (shrink)

We describe the Catholic natural law tradition by examining its origins in the medieval penitentials, the papal decretals, the writings of Thomas Aquinas, and seventeenth century casuistry. Catholic natural law emerges as a flexible ethic that conceives of human nature as rational and as oriented to certain basic goods that ought to be pursued and whose pursuit is made possible by the virtues. We then identify four approaches to natural law that have evolved within the United States during the twentieth (...) century, including the traditionalist, proportionalist, right reason, and historicist approaches. The normative implications of these approaches are discussed in relation to ethical issues in the tobacco industry, ITT under Geneen, the marketing of pharmaceuticals, affirmative action, and bribery. It is argued that Alasdair MacIntyre is correct in claiming that the natural law tradition is superior to the liberal ethics of modern deontology and utilitarianism. (shrink)

Este artigo apresenta um modelo do agente livre compatível com as teorias evolutivas e neurofisiológicas da mente e com base especificamente nas noções de liberdade em situação, de Sartre, e de racionalidade limitada, de Simon. Além disso, a noção de agência de controle de Skinner é generalizada, sendo aplicada também ao caso de estruturas cerebrais. O agente livre é descrito como o indivíduo humano cujo eu consciente escolhe e decide no contexto de múltiplas determinações tanto ambientais quanto neurofisiológicas. A autonomia (...) do agente humano é resultado dos processos que levam à aquisição das modalidades da consciência existencial, inclusive a consciência moral. O agente livre é alguém que alcança o autocontrole. (shrink)

Este artigo pretende articular algumas aproximações entre filosofia e literatura, através do filósofo Gilles Deleuze e do romancista Lewis Carroll. A Lógica do Sentido abre com um elogio ao mestre do non-sense, e a partir dela traça algumas considerações como, por exemplo, acerca do paradoxo. Assim, em primeiro lugar, pretende-se extrair através dos jogos de linguagem usados por Carroll os conceitoschave que marcam sua obra para, em seguida, ver como eles são retomados por Deleuze e, por fim, ver qual o (...) ponto de convergência destes autores de campos tão diferentes.

Neste artigo, analisamos a contenda entre Rudolf Carnap e Willard van Orman Quine em torno do empirismo, tendo como foco a discussão acerca dos chamados dois dogmas do empirismo. Especificamente, Carnap e Quine são dois dos principais nomes da Filosofia da Ciência no século XX e, embora tenham sido amigos próximos, Quine foi um dos maiores críticos de Carnap. Nesta empreita, Quine atribuiu à obra carnapiana dois dogmas, a saber, os chamados dogmas da distinção analítico-sintético e do reducionismo. Esta imagem (...) dogmática da obra de Carnap, não obstante, perpetuou-se de modo a constituir um retrato padrão da obra carnapiana dentro da Filosofia da Ciência. Contrários a esta interpretação de Quine, neste artigo, defendemos que o empirismo de Carnap não é dogmático, sendo alheio aos dogmas referidos por Quine. Consequentemente, argumentamos que, longe de discordarem no que tange a aspectos centrais do empirismo, Carnap e Quine estão de acordo em pontos decisivos acerca da concepção empirista da Ciência. De tal forma que, a principal divergência se encontra, não no empirismo, mas em suas respectivas propostas para a própria Filosofia da Ciência. (shrink)

Ao mesmo tempo que a disciplinaridade continua e se reforça, assiste-se crescentemente a um movimento que, para simplificar, designamos de interdisciplinaridade. As interdisciplinaridades com os seus objectos científicos próprios e os anseios de uma ciência da totalidade assumem crescente importância. Uma relevância que frequentemente é mais simbólica do que epistemológica, mais discursiva do que metodológica, mais emblemática do que construtora. 'Interdisciplinaridade - Antologia' reúne um conjunto de textos de importantes autores contemporâneos que fizeram do tema da interdisciplinaridade objecto de estudo (...) privilegiado. A sua publicação tem como principal propósito contribuir para o esclarecimento teórico do conceito de interdisciplinaridade e conceitos afins visando o aprofundamento do seu significado, a compreensão do seu valor e limites e um mais profundo entendimento das dificuldades em presença.

Na Crítica da razão pura (1787), Kant expõe uma teoria da analiticidade que pode ser resumida nos seguintes pontos principais: a contenção dos termos, a identidade entre eles e o princípio de contradição. Com base nestes critérios, Kant pensa que a aritmética não usa juízos analíticos. Em oposição, Frege defende, nos Fundamentos da aritmética (1884), que a teoria kantiana de analiticidade é equivocada e que juízos analíticos, incluindo os aritméticos, são lógicos. Pretende-se, portanto, com o uso da literatura secundária em (...) Hanna (2004), discutir as doutrinas de Kant e Frege acerca disso, sugerindo que a teoria de Kant não consegue se sustentar e que a teoria de Frege, embora problemática, possui um ponto promissor a partir da semântica de mundos possíveis de Plantinga (1974) e Kripke (2012).

O presente artigo tem por objetivo principal a exposição da teoria ontológica platônica sobre a definição de Ser e Não-Ser que se encontram no clássico diálogo “O Sofista”.

Até chegar a esta conclusão, o filósofo caminha em direção aos sofistas e observa o que eles faziam a fim de expor sua verdadeira natureza, falha e demagógica, além da superação e (...) refutação da ontologia parmenídica para findar a sua independência filosófica.

In _A Treatise of Human Nature_, Hume proposes a new philosophical method. This method results from integrating an empirically founded skepticism with an innovative study of the epistemic role of emotions. This combination of skepticism, empiricism, and moral psychology aims to establish a virtuous way of doing philosophy based on the regulation of our epistemic emotions. In this paper, I present the operating principles of this virtuous way of doing philosophy. The paper has three parts. I firstly claim that four (...) principles compose Hume’s philosophical methodology. I contend that the moderation of curiosity plays the central role among them. Secondly, I claim that that is the case because of the pernicious effects resulting when this passion becomes excessive and misplaced. Finally, I show the role of curiosity’s moderation in the Conclusion of Book 1 of the _Treatise_, to substantiate the claim that the crisis Hume there depicts illustrates his virtuous way of doing philosophy.
