El Test de Turing es un método tan controvertido como desafiante en Inteligencia Artificial. Se basa en la imitación de la conducta lingüística de humanos, y tiene como objetivo recabar evidencia empírica en favor de la tesis de que las máquinas programadas podrían pensar. Alan Turing, su creador, ha sido catalogado como conductista por la mayor parte de los comentaristas. En este capítulo muestro que no lo es. Por el contrario, Turing es un funcionalista, porque todo el énfasis del juego (...) de la imitación está en el engaño de la máquina hacia los humanos. Por ello el género es importante en dicho juego, al menos en su versión preliminar. (shrink)

The technique of forcing is almost ubiquitous in set theory, and it seems to be based on technicalities like the concepts of genericity, forcing names and their evaluations, and on the recursively defined forcing predicates, the definition of which is particularly intricate for the basic case of atomic first order formulas. In his [3], the first author has provided an axiomatic framework for set forcing over models of $\mathrm {ZFC}$ that is a collection of guiding principles for extensions over which (...) one still has control from the ground model, and has shown that these axiomatics necessarily lead to the usual concepts of genericity and of forcing extensions, and also that one can infer from them the usual recursive definition of forcing predicates. In this paper, we present a more general such approach, covering both class forcing and set forcing, over various base theories, and we provide additional details regarding the formal setting that was outlined in [3].

The minimal ordinal-connection axiom $$MOC$$ was introduced by the first author in R. Freire. (South Am. J. Log. 2:347–359, 2016). We observe that $$MOC$$ is equivalent to a number of statements on the existence of certain hierarchies on the universe, and that under global choice, $$MOC$$ is in fact equivalent to the $${{\,\mathrm{GCH}\,}}$$. Our main results then show that $$MOC$$ corresponds to a weak version of global choice in models of the $${{\,\mathrm{GCH}\,}}$$ : it can fail in models of the (...) $${{\,\mathrm{GCH}\,}}$$ without global choice, but also global choice can fail in models of $$MOC$$.

This paper begins the study of first-order functions, which are a generalization of truth-functions. The concepts of truth-table and systems of truth-functions, both introduced in propositional logic by Post, are also generalized and studied in the quantificational setting. The general facts about these concepts are given in the first five sections, and constitute a “general theory” of first-order functions. The central theme of this paper is the relation of definition among notions expressed by formulas of first-order logic. We emphasize that (...) logic is not concerned only with the consequence relation among notions expressed by formulas. It also attends to the relation of definition among notions, where a notion is defined from other notions. Sections 5 and 6 deal exclusively with the relation of definition among notions expressed by formulas of first-order logic. In these sections, we study the systems of first-order functions, which are the sets of first-order functions closed under definitions. Sections 7 and 8 are concerned with the relativization of first-order functions to a class of structures. The relativization to a class of structures is a fundamental operation which is used in order to relate the theory of first-order functions with set theory and first-order model theory, a subject which we have barely scratched the surface. The apparatus developed in this paper enables us to define what is a vehicle for the foundation of classical mathematics in set theory, and, in Sect. 8, we prove that first-order logic with one binary predicate variable is not a minimal vehicle for the foundation of classical mathematics in set theory. Sections 9 and 10 introduce further operations and ideals of first-order functions. Besides some results on the influence of the arguments of a first-order function, a result about definability is proved in Sect. 10.1. It is this theorem that provides necessary and sufficient conditions for a first-order function to be in a finitely generated ideal. In Sect. 11, this result is applied to the problem of predicate definability in classes of structures, the problem with which Beth’s theorem dealt in the case of elementary classes. (shrink)

The aim of the present paper is to provide a robust classification of valid sentences in set theory by means of existence and related notions and, in this way, to capture similarities and dissimilarities among the axioms of set theory. In order to achieve this, precise definitions for the notions of productive and nonproductive assertions, constructive and nonconstructive productive assertions, and conditional and unconditional productive assertions, among others, will be presented. These definitions constitute the result of a semantical analysis of (...) the notions involved. The conceptual clarification developed here results in a classification of valid sentences of set theory that goes against the standard view that extensionality is not an existence assertion.

This paper presents and discusses the most influential attempts to characterize physicalism without postulating relations of identity between the physical and the prima facie non-physical. The first section deals with a possible criticism that these attempts are misguided, since they contradict the physicalist slogan “everything there is physical.” In the second section, I elucidate the different formulations of the physicalist supervenience claim, and argue that none of them consists in an adequate characterization of physicalism. Three reasons are given in favor (...) of this conclusion: their compatibility with forms of dualism ; the fact that the supervenience relation is left unexplained; and Kim’s causal exclusion argument, which asserts that merely supervenient entities must be epiphenomenal. The third section presents the general features of another identity-independent attempt to characterize physicalism, namely realization physicalism. According to this view, tokens of prima facie non-physical types are realized by tokens of strictly physical types performing functional roles that specify the nature of the former. The third section also shows how realization physicalism deals with the objections that make physicalist supervenience claims inadequate for characterizing physicalism. Resumo O artigo apresenta e discute as tentativas mais influentes de caracterizar o fisicalismo sem postular relações de identidade entre o que é físico e o que é prima facie não físico. A primeira seção trata da possível crítica de que essas tentativas são equivocadas, porque contradizem o bordão fisicalista “tudo o que existe é físico”. Na segunda seção, elucido as diferentes formulações da tese fisicalista da superveniência, e argumento que nenhuma delas consiste em uma caracterização adequada do fisicalismo. Três razões são oferecidas em favor dessa conclusão: sua compatibilidade com formas de dualismo ; o fato de que a relação de superveniência é mantida sem explicação; e o argumento de Kim da exclusão causal, segundo o qual entidades meramente supervenientes devem ser epifenomenais. A terceira seção apresenta os aspectos gerais de outra tentativa de caracterizar o fisicalismo independente da identidade, a saber, o fisicalismo de realização. De acordo com essa posição, ocorrências de tipos prima facie não físicos são realizadas por ocorrências de tipos físicos quando estes executam os papéis funcionais que especificam a natureza dos primeiros. A terceira seção também revela como o fisicalismo de realização lida com as objeções que tornam as teses fisicalistas da superveniência inadequadas para a caracterização do fisicalismo. (shrink)

Resumen: El presente trabajo investiga la forma en que las ciencias sociales, principalmente chilenas, están respondiendo a las dispares demandas que reciben actualmente y que consisten en aportar a la comprensión crítica de fenómenos relevantes para la sociedad y adecuarse a las recientes transformaciones en la forma de producir y comunicar conocimiento científico incorporando mayores niveles de internacionalización, globalización, especialización y complejización. Para ello se realiza una revisión sistemática de la producción científica publicada sobre el movimiento estudiantil chileno, que constituye (...) uno de los movimientos sociales más relevantes de la historia reciente de Chile. Se sistematizaron 149 publicaciones editadas entre el año 2000 y el 2016. Los resultados muestran que la capacidad de las ciencias sociales chilenas para abordar estas demandas contradictorias es parcial, pues sus análisis críticos tienden a ser uniformes y de alcance temporal limitado, mientras que sus estudios empíricos no siempre poseen los niveles de internacionalización y complejidad demandados actualmente para participar en los circuitos internacionales de publicación.: The present work investigates the way in which social sciences, mainly Chilean, are responding to different demands that they are currently receiving and that consist of contribute to the critical understanding of phenomena relevant to society and adapt to recent transformations in the way of producing and communicating scientific knowledge, incorporating higher levels of internationalization, globalization, specialization and complexity. To this end, a systematic review of the scientific production published on the Chilean student movement is made. This movement is one of the most relevant in Chile's recent history. 149 publications were systematized, published between 2000 and 2016. The results show that the capacity of the Chilean social sciences to deal with these contradictory demands is partial, since their critical analyzes tend to be uniforms and limited in time, while their empirical studies do not always have the levels of internationalization and complexity currently demanded in international publishing circuits.

The common notion of artifacts characterizes them as the products of successful activities of their makers, guided by intentions that such objects would instantiate certain features, such as their specific functions. Many counterexamples, however, reveal the unsuitability of the common notion. In the face of this acknowledgment, the paper explores the possibility that features of artifacts, and more specifically, the possession of their functions, may arise, at least partially, from collective assignments. In order to achieve the mentioned goal, the paper (...) critically examines some notions and theses put forward by John Searle and others. Its main result, however, consists in offering and elucidating an original thesis, namely, that the functions of many artifacts would be maintained, partially, by forms of continuous collective intentionality, which can involve conscious or unconscious, active or inactive collective intentional states. Keywords: Artifacts, assignment of function, collective intentionality, maintenance of function. (shrink)

En este artículo argumentamos que la naturaleza pública o privada de la educación tiene una incidencia directa en las instituciones que conforman la realidad social. Para sustentar lo anterior, en primer lugar discutimos cómo, según Searle, habitamos un mundo de instituciones gobernadas por reglas y poderes deónticos, ontológicamente irreductibles. Luego, postulamos que la intencionalidad colectiva requiere de la confianza para mantenerse, y esta aumenta cuando gobiernan reglas y poderes deónticos en circunstancias normales. Finalmente, planteamos que la educación pública es una (...) institución que, a diferencia de la privada, privilegia el espacio de lo común. Sócrates es un ejemplo de esto, al proponer una filosofía que no solo busca la verdad, sino que además privilegia el reconocimiento de la ley por sobre la satisfacción inmediata de deseos e inclinaciones personales. De todo esto se explica el círculo virtuoso: la educación pública, al ser inclusiva y beneficiar a todos, potencia las instituciones sociales que tutelan ese interés y, dentro de ellas, el servicio público.

In previous research, acoustic characteristics of the male voice have been shown to signal various aspects of mate quality and threat potential. But the human voice is also a medium of linguistic communication. The present study explores whether physical and vocal indicators of male mate quality and threat potential are linked to effective communicative behaviors such as vowel differentiation and use of more salient phonetic variants of consonants. We show that physical and vocal indicators of male threat potential, height and (...) formant position, are negatively linked to vowel space size, and that height and levels of circulating testosterone are negatively linked to the use of the aspirated variant of the alveolar stop consonant /t/. Thus, taller, more masculine men display less clarity in their speech and prefer phonetic variants that may be associated with masculine attributes such as toughness. These findings suggest that vocal signals of men’s mate quality and/or dominance are not confined to the realm of voice acoustics but extend to other aspects of communicative behavior, even if this means a trade-off with speech patterns that are considered communicatively advantageous, such as clarity and indexical cues to higher social class.

In [13] M. Urchs comments on my paper [5]. I think these comments are very useful, especially because (on p. 38) the author decides to “proceed with some methodological remarks concerning Bressan’s account and his underlying attitude towards logical formalization in general”, and thus he refers not only to [5].

Este artículo sostiene que Platón constituye un interlocutor fructífero para la Teoría crítica. Desde un diálogo con Axel Honneth, argumentaremos primero que la metodología de crítica social desarrollada en la República posee elementos constructivo-racionales y reconstructivo-hermenéuticos. Luego, enfatizaremos dos conceptos prefigurados en dicha obra que, mediante Hegel, yacen en el trasfondo de la Teoría crítica, a saber: holismo y patología social. Ello nos permitirá articular, como conclusión, una “dialéctica de la justicia” que, en el sentido de Adorno & Horkheimer, recorre (...) la obra de Honneth. (shrink)

Neste trabalho, pretendemos avaliar criticamente algumas das teses de John McDowellsobre a natureza da virtude, tal como expostas em seu artigo “Virtue and Reason” e, ao fazê-lo,expor algumas de suas limitações. Mais especificamente, tratarei o que vejo como problemas emsua apresentação da virtude como uma forma de conhecimento, e sua proposta – corporificada natese da unidade das virtudes – de que as virtudes comumente reconhecidas deveriam ser vistascomo manifestações parciais da virtude enquanto tal. Também enfocarei a assertiva de McDowellde que (...) o conhecimento que constitui a virtude não pode ser visto como tendo um conteúdoproposicional que se preste a uma codificação em princípios de conduta – a tese de nãocodificabilidade– e a relação da postura pessoal de McDowell com a empreitada mais ampla daética de virtudes.

This article proposes an exposition and analysis of perceptions intrinsic to rituals carried out with the use of the jurema plant, especially when mixed with Syrian rue (juremahuasca) in contexts of contemporary esoteric re-actualizations in Brazil. These rituals are conducted by people who look at jurema as a spiritual path, once acquainted with its psychedelic properties. We highlight the mystical attributes and the cultural bricolage elaborated by these individuals, who conduct ceremonies in ritual spaces in which participants experience altered states (...) of perception and consciousness. Considered as an entheogen, jurema leads to states of mystical transformation in people. Such personal changes are often considered by users as the rhetoric of healing. Life stories and ethnographic contexts form the background of the article, which seeks to advance understandings about jurema based on speculations around the intertwining of the themes of consciousness, mysticism, and healing.

College students have become more representative as blood donors, mainly to help other people. This study ascertained the association between spirituality and adherence or intention to donate blood in post-graduate students. In this quantitative and cross-sectional study, participants were 281 students from a post-graduate programme at a Brazilian public university. After complying with ethical requirements, data were collected through a questionnaire for sociodemographic characterization and identification of blood donation practices, followed by the Spiritual Well-Being Scale. Descriptive statistics and parametric tests (...) were used for data analysis. A total of 74% of the participants were female and 26% were male. Previous experience and/or intention to donate blood were found in 75.3%; 14.3% donated blood periodically. In addition, 12.2% were not adept to donation and 12.5% were inapt. Spiritual Well-Being scores were similar between individuals who are not adept and those who donate periodically. In conclusion, in the sample, spirituality and blood donation are not associated, but spiritual well-being and gender are. To enhance blood donation, further research is needed. (shrink)

Uma exegese filosófica da problemática do niilismo na obra de Cioran, partindo de uma análise lexicográfica dos usos discursivos deste conceito, mas sem se limitar a ele (que está longe de ter um estatuto privilegiado no discurso cioraniano). Levando em conta a reviravolta que marca uma cisão no âmago da obra de Cioran, na transição entre seus escritos romenos e franceses, e combinando à lexicografia um procedimento propriamente hermenêutico do tema do niilismo, conclui-se com uma reflexão sobre o nexo entre (...) niilismo e humor na obra francesa de Cioran, notadamente em Silogismos da amargura (1952), em contraste com o niilismo da “seriedade infinita” (sinônimo de desespero) que caracteriza a sua obra romena.

Adult learners demand teaching innovations that are ever more rapid and attractive. As a response to these demands and the challenges of skills training, this article presents a conceptual analysis that introduces competitive debate as an impact training model. The aim is to learn whether debate can be considered to fall within the frame of gamification, so that the full potential of debate as gamification can be exploited. There is a significant research gap regarding competitive debate as a game, with (...) the training mechanics for adult learners remaining practically unexplored. Through a conceptual analysis of game, game experience, and gamification, and their respective characteristics, we conclude that competitive debate is an ideal instrument for gamification. (shrink)

Within the banking community, the argument about sustainability and profitability tends to be inversely related. Our research suggests this does not need to be strictly the case. We present a credit score system based on sustainability issues, which is used as criteria to improve financial institutions’ lending policies. The Sustainability Credit Score System is based on the analytic hierarchy process methodology. Its first implementation is on the agricultural industry in Brazil. Three different firm development paths are identified: business as usual, (...) sustainable business, and future sustainable business. The following six dimensions are present in the SCSS: economic growth, environmental protection, social progress, socio-economic development, eco-efficiency, and socio-environmental development. The results suggest that sustainability is not inversely related to profit either from a short- or long-term perspective. The SCSS is related to the Equator Principles, but its application is not driven to project financing. It also deals with short- and long-term risks and opportunities, instead of short-term sustainability impacts. (shrink)

La expulsión de los poetas fuera de la ciudad ideal, política elaborada en la República de Platón, es uno de los episodios más comentados en la historia de la filosofía, de modo que no parece haber lugar a novedades sobre el tema. No obstante, en este artículo me dedicaré a un aspecto que parece desatendido por los comentaristas del texto: hay una relación íntima entre la poesía y la oligarquía, entre los imitadores y el régimen de gobierno que ocupa el (...) centro de la escala que va de los mejores a los peores. Entre los poetas caracterizados por Platón y los oligarcas, propondré, la diferencia es únicamente de grado, no de naturaleza, en el mismo sentido en que el filósofo establece la diferencia entre un amo y un rey, ambos por igual gobernantes. A tal fin me detendré en el tratamiento de las figuras del suplicante, el imitador, el oligarca y Odiseo (como personaje que las sintetiza), para atender a los aspectos comunes que hacen posible su reunión. Esto nos llevará a algunas conclusiones sobre el conflicto entre Platón y el anonimato. (shrink)

DEUS EXISTE OU SERIA A FÉ RELIGIOSA APENAS UM DELÍRIO UNIVERSAL? Em O ceticismo da fé, o teólogo e arqueólogo Rodrigo Silva traz um estudo profundo sobre a “existência” de Deus. O objetivo primário desta obra, entretanto, não é um convencimento sobre Deus, mas acompanhar crentes e descrentes nessa jornada sem-fim inerente a todo ser humano em busca da “verdade”. Pois a fé comporta, sim, muitas dúvidas. René Descartes que o diga. Mesmo não sendo teólogo, nem pretendendo produzir uma (...) declaração de fé religiosa, ele ajudou Rodrigo Silva a ter umdos mais brilhantes insights confessionais: “o homem deve desconfiar de tudo para poder acreditar em alguma coisa”.Não se pretende aqui enganar o leitor ou insultar sua inteligência, nem apresentar qualquer soberba confessional. Rodrigo Silva é crente, sim, mas a inspiração para este trabalho veio justamente de sua descrença. E apesar das respostas que encontrou nesses quase trinta anos de estudo, o autor não foge de algumas questões polêmicas e provocadoras que envolvem Deus, como “Por que ele se esconde?”, “Por que um Deus de amor matou e mandou matar tanta gente no Antigo Testamento?” e “Onde eleestava durante o massacre de Auschwitz?”.Este livro convida o leitor, seja o ateu ou o religioso mais convicto, a questionar, a pensar, a se comprometer sinceramente com a dúvida, a fim de que a sua sistematização o conduza a grandes certezas.

Dignity is a value inherent to all human beings, guaranteed to every individual from birth, and influenced by culture and society. It is protected by various laws and declarations, and represents one of the fundamental human rights. Preserving human dignity is an essential aspect of nursing practice and a central element of care. Dignity is a highly subjective and personal concept; there may be variations in the way that patients perceive it and in the ways that nurses can guarantee it. (...) A systematic review of the qualitative literature was conducted to obtain a comprehensive understanding of adult patients’ perceptions of dignity in a hospital setting. This review adhered to the PRISMA Statement for reporting systematic reviews, and the results were reported in accordance with the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. Major databases (PubMed, CINAHL, Scopus, and PsycINFO) were consulted and resulted in the inclusion of 21 studies. Methodological quality was assessed using the Critical Appraisal Skills Program (CASP) Checklist for Qualitative Studies. Six main themes emerged from the data analysis: (1) The concept of dignity and its various dimensions; (2) The significance of maintaining one’s own privacy and confidentiality; (3) The hospital environment’s influence on patients’ dignity; (4) Healthcare professionals’ characteristics and behaviours that affect dignity; (5) The role of communication and the relationship with healthcare providers; and (6) The patient’s ability to make choices and be involved actively in their care. These findings underscore the importance of understanding caregivers’ perspectives on dignity to ensure that they provide respectful and dignified care and treatment that prioritizes the patient’s mental and physical needs.

In a recent paper in this journal, David Chalmers introduced the meta-problem of consciousness as “the problem of explaining why we think consciousness poses a hard problem” (Chalmers, 2018, p. 6). A solution to the meta-problem could shed light on the hard problem of consciousness. In particular, it would be relevant to elucidate whether people’s problem intuitions (i.e. intuitions holding that conscious experience cannot be reduced to physical processes) are driven by factors related to the nature of consciousness, or rather (...) by factors that are independent of consciousness. Whether people hold problem intuitions, and what factors drive those intuitions, are largely empirical questions. However, there is a lack of empirical research on these issues to date. The results of four studies will show that (1) problem intuitions are not widespread, and (2) when they arise, they do so because of factors that are unrelated to the nature of consciousness. This suggests that consciousness is, after all, not so problematic. (shrink)

We present the findings of a worldwide survey that was administered to business ethic scholars to better understand journal quality within the business ethics academic community. Based upon the data from the survey, we provide a ranking of the top 10 business ethics journals. We then provide a comparison of business ethics journals to other mainstream management journals in terms of journal quality. The results of the study suggest that, within the business ethics academic community, many scholars prefer to publish (...) in the top business ethics academic journals over other mainstream management journals. Furthermore, the results of the study suggest that within the business ethics academic field there are two dominant academic communities: one in Europe and one in North America. Each of these academic communities has its own preferred publication outlets, suggesting a potentially problematic bifurcation of business ethics scholarship. (shrink)
