Este trabajo presenta y analiza dos posturas acerca de las representaciones y clasificaciones científicas que Ian Hacking en ¿La construcción social de qué? denomina realismo o estructurismo inherente y nominalismo. La primera sostiene que las divisiones del conocimiento científico expresan o reflejan divisiones estructurales de la realidad a la que se refieren, en tanto que la segunda considera que toda división o estructura atribuida por la ciencia a la realidad se encuentra sólo en las representaciones mismas. Se sostiene que tal (...) criterio clasificatorio resulta pertinente y fructífero para las discusiones actuales acerca de la naturaleza del conocimiento científico, que pone de relieve diversas cuestiones profundas e intensamente debatidas a lo largo de la historia de la filosofía, y que el empleo del término “nominalismo” –a pesar de su polisemia y de ser poco utilizado actualmente en la filosofía de la cienciaes acertado por cuanto la discusión es en gran medida semántica, ya que se basa en dos concepciones contrapuestas acerca de la naturaleza del lenguaje humano.

La vida en el laboratorio. La construcción social de los hechos científicos (Latour y Woolgar, 1979) sostiene que los hechos y las entidades cuya existencia ha sido establecida por la ciencia no son descubrimientos sino “construcciones sociales” llevadas a cabo por los científicos mediante “versiones” o “explicaciones ordenadas” al establecer acuerdos (“cierres de controversias”). Se sostiene, siguiendo la terminología de la filosofía de la ciencia actual, que este argumento es una forma de antirrealismo científico lingüístico, tesis sustentada también por autores (...) como Richad Rorty, Nelson Goodman, Thomas Kuhn y Ludwik Fleck, que es inconsistente y que confunde niveles de lenguaje, porque al referirse metalingüísticamente a las teorías, “versiones” o descripciones científicas no diferencia entre cosas metafísicamente diferentes: la existencia (o la inexistencia) de una entidad o un hecho, y la creencia compartida o la descripción de la existencia (o la inexistencia) de esa entidad o ese hecho. Ello lo lleva a cometer el error categorial de atribuir características del lenguaje (como la de explicar o la de ser usado) a cosas que no son lingüísticas (como la naturaleza o un hecho). Si bien tanto la versión de Latour y Woolgar como las demás no diferencian entre que un conjunto de personas crean que existe lo que la ciencia afirma y las propias afirmaciones de la ciencia sobre lo que existe, ambas cosas ocurren en la realidad social, por lo que el argumento constructivista –tal como el de Goodman de que una constelación ha sido creada mediante una versión, el de Kuhn de que “los conceptos” “conforman el mundo al que se aplican” o el de que los hechos y las teorías no son categóricamente separables, el de Fleck de que la sífilis no existe independientemente de las representaciones lingüísticas de la medicina o el de Rorty de que el color de la piel de un dinosaurio depende de la descripción científica sobre él, por ejemplo-, en la medida en que niega la existencia independiente de esos hechos y entidades no es más que una forma actual de lo que se llamó idealismo metafísico, en la que no se considera como entidad primitiva las “ideas” o estados de conciencia sino hechos de sociedad humana como las afirmaciones y los significados científicos y las creencias que generan en las personas.

Este texto presenta, y en cierta medida analiza, ambigüedades existentes en textos de lógica y filosofía de la lógica (como la interpretación de los llamados principios, postulados, leyes o verdades lógicas, la coexistencia de la tesis de que toda relación presupone la existencia de al menos dos relata y la de que una cosa puede relacionarse consigo misma, o la llamada "paradoja del mentiroso") bajo el supuesto de que, dado que la lógica no es anterior a la semántica, un análisis (...) semántico puede mostrar no solo que tal polisemia sugiere que ni la disciplina ni las teorías lógicas son tan rigurosas como se ha afirmado, sino también que varias afirmaciones de esas disciplinas carecen de sentido.

Este trabajo consiste en un análisis de la tesis expuesta en el artículo de 1980 “Do the laws of physics state the facts?” de Nancy Cartwright, según la cual las leyes fundamentales de la física no “describen los hechos” porque, respecto de ellas, verdad y explicatividad se excluyen mutuamente. El texto fue luego republicado como tercer ensayo de su libro How the Laws of Physics Lie (1981), del que Mauricio Suárez afirma que el “trade-off” entre verdad y explicación es su (...) “tesis central”. El problema abordado es propio de la filosofía de la ciencia: cómo deben interpretarse o entenderse las leyes teóricas. Específicamente, si deben considerarse descripciones de hechos (es decir, literalmente, en el sentido de que existe una realidad con independencia de las leyes mismas y que las características de la realidad pueden ser representadas mediante el lenguaje: que tienen valor de verdad) o cumplen otra función dentro del conocimiento científico. El artículo de Cartwright estudia el caso del papel que cumplen las leyes fundamentales de la física cuando forman parte de las explicaciones por cobertura legal del tipo denominado por John Stuart Mill “por composición de causas”. Analiza la explicación de la atracción gravitatoria que hay entre dos objetos en un sistema físico en el que están presentes, además de las fuerzas gravitatorias, fuerzas eléctricas. Afirma que en ella la ley de la teoría de Newton tomada individualmente no describe lo que ocurre, no es verdadera. Pero no porque sea falsa sino porque su función o “rol” no consiste en “describir hechos” sino en ser parte de explicaciones científicas. Pero este argumento de la filósofa de la escuela de Stanford presenta dificultades semánticas, como el uso con dos sentidos diferentes del término teórico “fuerza”. Asimismo, es problemático que asuma que los hechos físicos son observables. Y no es correcta la afirmación de que una ley científica “se hace verdadera”, ni que “explica” hechos singulares, ni que “describe” en una explicación. (shrink)

A pesar de que Bruno Latour es considerado iniciador de un área académica denominada estudios de la ciencia, no se ha destacado lo suficiente que sus textos constituyen fundamentalmente una teoría metafísica cuya tesis central –mantenida a lo largo de la mayor parte de su obra- es que no hay una diferencia real entre “palabra y mundo”, entre un enunciado que se refiere a un hecho y ese mismo hecho, sino una serie de relaciones o “redes” (que denomina “fluido”, “la (...) masa de las transformaciones” o “referencia circulante”) donde ocurren estabilizaciones transitorias. En tanto niega que entidades y estados de cosas efectivos existan independientemente, ya no de que una conciencia piense en ellos, sino de las afirmaciones que hay en la cultura sobre su existencia, este enfoque es una variante, de carácter semántico y social, de lo que la filosofía moderna denominó idealismo metafísico. Pero tanto el problema metafísico de la existencia como el de la existencia independientemente de algo se enfrentan con la dificultad semántica de que ningún argumento descriptivo puede dejar de aludir a sus referentes, por lo que ninguno puede probar que exista algo independientemente del lenguaje, sino sólo suponerlo al adoptar una ontología. (shrink)

Parece haber una inconsistencia en el hecho de que se acepta que en la historia de la ciencia hay cambios teóricos con cambio de ontologías, de maneras de explicar, de términos y significados científicos, se descubren cosas nuevas, se modifican teorías vigentes, surgen nuevas disciplinas científicas y se formulan nuevas teorías sobre nuevos aspectos de la realidad, y también que, según la propia ciencia, la realidad no permanece fija (pues El Universo se expande, antes no había seres vivientes en La (...) Tierra, robots ni organismos genéticamente modificados, surgen nuevas especies, hay glaciaciones y cosas así) y, sin embargo, al mismo tiempo se suele considerar que lo que el conocimiento científico afirma que existe es lo que existe y se comporta como él lo describe. Pero lo que la ciencia afirma que existe es su ontología, un conjunto de referentes de expresiones lingüísticas que las personas incorporamos en nuestra idea de realidad, de modo que luego de un cambio ontológico ésta resulta modificada y –por ejemplo- ya no creemos que exista el flogisto o un espacio físico absoluto, sino otras cosas. Esto significa que hablar de galaxias o de virus es usar un metalenguaje que se refiere a ciertas teorías científicas, y que decir que existen galaxias es asumir metalingüísticamente la ontología de la ciencia actual: las personas hoy no creen que exista el flogisto ni lo afirman porque no lo afirma la ciencia (no es un referente científico). Consecuentemente, no es adecuado interpretar que una oración como “existen planetas” es verdadera en el sentido correspondentista (que es parte del realismo metafísico de la vida cotidiana o actitud natural y del lenguaje humano), porque todo argumento que afirme la existencia de algo independientemente de él, en realidad, lo supone al adoptar una ontología. Si no fuese así, cuando en el pasado se creía y se afirmaba la existencia del flogisto, miasmas o un espacio físico absoluto porque la ciencia lo afirmaba, esas oraciones hubiesen sido correspondentistamente verdaderas y habrían designado partes de la realidad: el flogisto, miasmas y el espacio físico absoluto.

The problem of deviant causation has been a serious obstacle for causal theories of action. We suggest that attending to the problem of deviant causation reveals two related problems for causal theories. First, it threatens the reductive ambitions of causal theories of intentional action. Second, it suggests that such a theory fails to account for how the agent herself is guided by her reasons. Focusing on the second of these, we argue that the problem of guidance turns out to be (...) related to a number of other issues in the literature on action explanation, and that it is much more general: it threatens not only causal theories but any theory of action. Finally, we suggest that a certain version of the view that acting has a constitutive or formal aim can overcome this problem. (shrink)

'We desire all and only those things we conceive to be good; we avoid what we conceive to be bad.' This slogan was once the standard view of the relationship between desire or motivation and rational evaluation. Many critics have rejected this scholastic formula as either trivial or wrong. It appears to be trivial if we just define the good as 'what we want', and wrong if we consider apparent conflicts between what we seem to want and what we seem (...) to think is good. In Appearances of the Good, Sergio Tenenbaum argues that the old slogan is both significant and right, even in cases of apparent conflict between our desires and our evaluative judgements. Maintaining that the good is the formal end of practical inquiry in much the same way as truth is the formal end of theoretical inquiry, he provides a fully unified account of motivation and evaluation.

A implementação de tecnologias móveis de informação e comunicação no suporte à Saúde Mental tem atraído a atenção das autoridades. Com a ascensão das Inteligências Artificiais, esse movimento pode ser impulsionado de maneira exponencial. Nesse cenário, esta revisão tem como objetivos verificar a aplicabilidade das Inteligências Artificiais (IAs) na Saúde Mental e analisar os aspectos que favorecem a relação entre IAs e usuários. Para tanto, realizou-se uma revisão sistemática nas bases de dados PubMed e Biblioteca Virtual em Saúde, no período (...) de 25 de maio a 23 de junho de 2023. Selecionamos os 100 primeiros artigos mais relevantes com as palavras-chave: “Inteligência Artificial”, “Saúde Mental”, “Chatbots”, “Psicoterapia”, “Psicologia” e suas equivalentes em inglês. Os critérios de inclusão foram: acesso aberto, publicação a partir de 2018, em português ou inglês e menção à atuação de IAs no âmbito da Saúde Mental. Para reduzir o risco de viés, excluímos os estudos que não mensuraram o impacto das intervenções por meio de métodos experimentais ou quase-experimentais. Para a síntese dos dados, delimitaram-se alguns pontos específicos de análise, como “Resultado da intervenção”, “Aspectos que favorecem a relação”, entre outros. Atenderam aos critérios de inclusão 24 estudos, dos quais 17 apresentaram resultados positivos em suas intervenções. O uso de IAs na Saúde Mental possui grande potencial de expansão e os resultados obtidos neste trabalho podem guiar a implementação dessas práticas e futuras pesquisas na área. (shrink)

The COVID‐ 19 pandemic is a critical test for the already overburdened and mostly underfunded public healthcare systems of Latin America. In a region that suffers from severe inequalities, public healthcare systems are the only source of medical care for a large sector of the population who work in the informal economy or are unemployed. State‐run hospitals and clinics are already overstressed by continuous demand for treatment of vector‐borne diseases and community‐acquired infections as well as high rates of non‐communicable diseases. (...) Ideological misconceptions and denial among Latin America’s political leaders prevented timely preparations for the pandemic and added to chronic governance problems. As ethical expertise in Latin America focuses on research ethics, few hospitals in the region have functioning clinical ethics committees or clinical ethics policy, forcing healthcare personnel to make excruciating treatment decisions in an environment dominated by material scarcity and public distrust. This essay examines the emergence of COVID‐19 in Latin America and the serious challenge that it poses for Latin America's public healthcare systems. (shrink)

This article tries to establish the scopes and limits of the main interpretations on Newton during the 20th century, highlighting on the one hand the textual evidence at disposal, and on the other hand the philosophical and epistemological currents that defines the main features of those interpretations. It will be shown that the rejection of positivism is not sufficient condition for establishing an adequate interpretation and, together with the strengthening of the research from Newton’s manuscript, it is necessary a wider, (...) and more detailed model that those established by some of the most outstanding scholars like Alexandre Koyré, I. Bernard Cohen, Betty Dobbs, and Richard Westfall. (shrink)

El artículo presenta, en primer lugar, la visión crítica del filósofo español José Luis L. Aranguren, sobre la democracia establecida en España y en el entorno occidental y su propuesta de una «democracia como moral». En segundo lugar, se aborda el papel que debería jugar, según Aranguren, una verdadera izquierda política en toda democracia y, a partir del concepto clave de heterodoxia –en este caso en cuanto des-identificación–, se abre una reflexión acerca del propio ser de la izquierda y de (...) las llamadas políticas de la identidad. Por último, a modo de conclusión, se apunta a un posible diálogo del pensamiento arangureniano con debates actuales sobre la democracia y dentro de la misma izquierda en torno a todas esas cuestiones identitarias.

The marketplace has seen significant growth in the demand for ‘ethical’ behavior, and banks are seeking to leverage customers’ perception in order to build a sustainable competitive advantage. In consequence, the concepts of corporate social responsibility and corporate reputation are of vital concern for academics and managers in terms of their potential impact on customers. This study seeks to contribute to the literature by examining the mediating role of corporate reputation on the relationship between perceived corporate social responsibility and customer (...) loyalty. The study also takes into consideration the role played by bank type in the mediation effect. To achieve this aim, a study was performed comprising 572 personal surveys in the Basque Country. The results showed that corporate reputation partially mediated the relation between corporate social responsibility and customer loyalty. On the other hand, bank type is shown not to moderate the mediation effect. The results have important implications for practitioners wishing to manage their relations with customers. (shrink)

Scientists have always attempted to explain the world in terms of a few unifying principles. In the fifth century B.C. Democritus boldly claimed that reality is simply a collection of indivisible and eternal parts or atoms. Over the centuries his doctrine has remained a landmark, and much progress in physics is due to its distinction between subjective perception and objective reality. This book discusses theory reduction in physics, which states that the whole is nothing more than the sum of its (...) parts: the properties of things are directly determined by their constituent parts. Reductionism deals with the relation between different theories that address different levels of reality, and uses extrapolations to apply that relation in different sciences. Reality shows a complex structure of connections, and the dream of a unified interpretation of all phenomena in several simple laws continues to attract anyone with genuine philosophical and scientific interests. If the most radical reductionist point of view is correct, the relationship between disciplines is strictly inclusive: chemistry becomes physics, biology becomes chemistry, and so on. Eventually, only one science, indeed just a single theory, would survive, with all others merging in the Theory of Everything. Is the current coexistence of different sciences a mere historical venture which will end when the Theory of Everything has been established? Can there be a unified description of nature? Rather than an analysis of full reductionism, this book focuses on aspects of theory reduction in physics and stimulates reflection on related questions: is there any evidence of actual reduction? Are the examples used in the philosophy of science too simplistic? What has been endangered by the search for (the) ultimate truth? Has the dream of reductionist reason created any monsters? Is big science one such monster? What is the point of embedding science Y within science X, if predictions cannot be made on that basis? (shrink)

Deontological theories face difficulties in accounting for situations involving risk; the most natural ways of extending deontological principles to such situations have unpalatable consequences. In extending ethical principles to decision under risk, theorists often assume the risk must be incorporated into the theory by means of a function from the product of probability assignments to certain values. Deontologists should reject this assumption; essentially different actions are available to the agent when she cannot know that a certain act is in her (...) power, so we cannot simply understand her choice situation as a “risk-weighted” version of choice under certainty.

This article sheds light on Hobbes’s concept of the state of nature through a reading of his conception of knowledge, which makes it possible to relate him with the ‘New Science’ or the Scientific Revolution. In consequence, this article describes Hobbes with some problems and traditions of the Scientific Revolution through a fresh reading of his theory of knowledge, whence the concept of the state of nature is redefined in terms of integral cause; this makes it possible to argue the (...) need for Commonwealth, excluding the anthropological pessimism traditionally attributed to Hobbes.

. The uniform prior distribution is often seen as a mathematical description of noninformativeness. This paper uses the well-known Three Prisoners Paradox to examine the impossibility of maintaining noninformativeness throughout hierarchization. The Paradox has been solved by Bayesian conditioning over the choice made by the Warder when asked to name a prisoner who will be shot. We generalize the paradox to situations of N prisoners, k executions and m announcements made by the Warder. We then extend the consequences of hierarchically (...) placing uniform and symmetrical priors for the probability p of the Warder naming Prisoner B, say. We prove that breaks of indifference and neutrality caused by assignment of uniform and symmetrical priors in lieu of degenerate indifference probabilities hold in general. Speaking of unknown probabilities or of probability of a probability must be forbidden as meaningless.

The main purpose of this thesis is to explore de Finetti's ideas and contributions to decision theory. Such ideas are not as well-known as his work on probability. ;The first part of the work is placed in a unisubjective decision-making context. It starts by including a discussion on predictivism, an approach to statistics which de Finetti insisted on and which has only recently been rediscovered and advocated. ;The second part is placed in the context of group, or multisubjective, decision-making. This (...) area is well-known for its negative results, starting with Arrow's impossibility theorem. While being aware of such difficulties, de Finetti made important contributions to this field, which he saw as the appropriate context to approach basic concepts such as "objectivity" and Wald's admissibility theorem. Such concepts, together with exchangeability, illuminate the Bayesian position by also making connection with the non-Bayesian approach. ;The last part of the work starts with a critical discussion of classical methods which are unacceptable for Bayesians. Finally, an important application problem--environmental stress screening--is solved from a Bayesian predictivist point of view. (shrink)

An effective method to increase the number of potential cadaveric organ donors is to make people donors by default with the option to opt out. This non-coercive public policy tool to influence people’s choices is often justified on the basis of the as-judged-by-themselves principle: people are nudged into choosing what they themselves truly want. We review three often hypothesized reasons for why defaults work and argue that the as-judged-by-themselves principle may hold only in two of these cases. We specify further (...) conditions for when the principle can hold in these cases and show that whether those conditions are met is often unclear. We recommend ways to expand nationwide surveys to identify the actual reasons for why defaults work and discuss mandated choice policy as a viable solution to many arising conundrums. (shrink)

This paper reports the framework, method and main findings of an analysis of cultural milieus in 4 European countries. The analysis is based on a questionnaire applied to a sample built through a two-step procedure of post-hoc random selection from a broader dataset based on an online survey. Responses to the questionnaire were subjected to multidimensional analysis-a combination of Multiple Correspondence Analysis and Cluster Analysis. We identified 5 symbolic universes, that correspond to basic, embodied, affect-laden, generalized worldviews. People in this (...) study see the world as either a) an ordered universe;b) a matter of interpersonal bond;c) a caring society;d) consisting of a niche of belongingness;e) a hostile place. These symbolic universes were also interpreted as semiotic capital: they reflect the capacity of a place to foster social and civic development. Moreover, the distribution of the symbolic universes, and therefore social and civic engagement, is demonstrated to be variable across the 4 countries in the analysis. Finally, we develop a retrospective reconstruction of the distribution of symbolic universes as well as the interplay between their current state and past, present and future socio-institutional scenarios.

The practice of parkour in urban spaces by young people, especially those who call themselves traceurs, illustrates how identities are formed in an ephemeral way by reinterpreting spaces in the city – briefly and without leaving a trace. However, in a sort of paradox, these interventions are registered in the socio-digital spectrum, tokenistically anchoring and incorporating them into conversations and social interactions. This work aims to explain the practice of the sport called parkour as a socio-semiotic phenomenon. We have used (...) some zones of Mexico City as a specific case for our approach. The foregoing leads to the conclusion that the meaning of parkour goes beyond its recreational role and places it as a relevant piece of identity for excluded urban social groups – even though these practices have been appropriated by marketing strategies. Our approach will use a cultural semiotics perspective, as well as direct observations and interviews as research techniques. (shrink)

Two Lagrangians L and L′ are equivalent if the equations of motion derived from them have the same set of solutions. In that case, a matrix Λ may be defined which has the property that the trace of any analytic function of Λ is a constant of the motion. We extend this trace theorem to the case of classical field theory and discuss some of the implications for quantum theory and for procedures for finding equivalent Lagrangians.
