There is no known syntactic characterization of the class of finite definitions in terms of a set of basic definitions and a set of basic operators under which the class is closed. Furthermore, it is known that the basic propositional operators do not preserve finiteness. In this paper I survey these problems and explore operators that do preserve finiteness. I also show that every definition that uses only unary predicate symbols and equality is bound to be finite.

Information is a notion of wide use and great intuitive appeal, and hence, not surprisingly, different formal paradigms claim part of it, from Shannon channel theory to Kolmogorov complexity. Information is also a widely used term in logic, but a similar diversity repeats itself: there are several competing logical accounts of this notion, ranging from semantic to syntactic. In this chapter, we will discuss three major logical accounts of information.

While collaboration has always played an important role in many cases of discovery and creation, recent developments such as the web facilitate and encourage collaboration at scales never seen before, even in areas such as mathematics, where contributions by single individuals have historically been the norm. This new scenario poses a challenge at the theoretical level, as it brings out the importance of various issues which, as of yet, have not been sufficiently central to the study of problem-solving, discovery, and (...) creativity. We analyze the case of collective and web-based proof events in mathematics, which share their temporal and social nature with every case of collective problem-solving. We propose that some ideas from cognitive architectures, in particular, the notion of codelet—understood as an agent engaged in one of a multitude of available tasks—can illuminate our understanding of collective problem-solving and act as a natural bridge from some of the theoretical aspects of collective, web-based discovery to the practical concern of designing cognitively inspired systems to support collective problem-solving. We use the Pythagorean Theorem and its many proofs as a case study to illustrate our approach. (shrink)

Renal replacement therapy is the indicated treatment for individuals with chronic kidney disease (CKD) to survive. However, not all sick people have access to the same treatment. This study compares renal care in two developing countries with different health systems. Specifically, it explores hemodialysis treatment from the perspective of low‐income individuals. A qualitative, comparative study was performed in Brazil and Mexico. Using purposive sampling, the research was based on open‐ended interviews with nineteen participants with kidney failure undergoing hemodialysis treatment in (...) public hospitals and ten relatives. According to our results, Brazilian participants perceived hemodialysis care as satisfactory because of health personnel courtesy as well as free access to dialysis treatment, prescription drugs, hospitalization and transportation. However, they reported deficiencies in the care they were receiving due to shortages of specialists, prescription drugs, laboratory tests and transportation. Mexican participants, in contrast, highlighted the catastrophic costs of medical care because they had no free access to renal therapy, nor adequate financial resources. Our findings suggest that low‐income Brazilian CKD sufferers experience renal care differently, as they are more satisfied and face less obstacles with hemodialysis compared with those of Mexico. More studies on the topic are needed. (shrink)

En este artículo se investiga la índole y supuestos filosóficos básicos de dos perspectivas metafísicas y epistemológicas contrapuestas en torno a la célebre prueba ontológica de la existencia de Dios. Tales perspectivas son, por un lado, la esencia lista o realista fenomenológica, para la que, por admitir la objetividad y trascendencia de las llamadas "cualidades eidéticas necesarias", la prueba es válida y concluyente; por otro, la perspectiva existencialista o conceptualista, que, al negar tal objetividad y trascendencia, rechaza la validez de (...) la prueba. De este modo, la posición ante este problema metafísico fundamental puede constituir un criterio básico de diferenciación entre defensores y detractores del célebre argumento anselmiano. (shrink)

Nuestra intención en este artículo es exponer la concepción berkeleyana entorno al tan debatido problema de la filosofía de la modernidad que concierne a la relación, conocimiento y exterioridad. Éste constituye, en efecto, núcleo esencial de las filosofías de autores tan representativos de la época como Locke, Hume, Condillac y el propio Berkeley, entre otros. No obstante, la singularidad del planteamiento berkeleyano al respecto es tal, que bien merece por nuestra parte una reflexión antenta y por separado. Además, la influencia (...) que su aportación peculiar ejerció sobre determinados filósofos, como, por ejemplo, Condillac y Kant, y a través de ellos sobre buena parte de la filosofía posterior fue de tal índole, que sin el cabal conocimiento de ella no podría entenderse la relevancia y significación del idealismo gnoseológico en sus diferentes tipos y modalidades. En una primera sección, meramente introductoria, acometemos la exposición de la metafísica de Berkeley, destacándose sobre todo su teoría del inmaterialismo ; con ello se pretende subrayar en principio el carácter peculiar que forzosamente habrá de presentar su concepción de lo externo. El tratamiento de ésta constituye propiamente el contenido de la segunda sección, en la que, además de la identificación entre contenido sensible y realidad y de la apelación a la instancia divina como garante último de ésta, se destaca el papel preponderante que desempeña el sentido del tacto en el proceso de aprehensión de la exterioridad.

Nuestra pretensión en este artículo es modesta: nos proponemos únicamente poner de relieve el doble sentido de los términos "idea" y "sensación" en la filosofía de los siglos XVII y XVIII. Como es sabido, ambos términos constituyen, respectivamente, el núcleo esencial del racionalismo y el empirismo. La idea para el primero y la sensación para el segundo se erigen ciertamente en piezas gnoseológicas clave sin las cuales ni uno ni otro podrían ser cabalmente comprendidos.

Perhaps the hottest topic in the philosophy of chemistry is that of the relationship between chemistry and physics. The problem finds one of its main manifestations in the debate about the nature of molecular structure, given by the spatial arrangement of the nuclei in a molecule. The traditional strategy to address the problem is to consider chemical cases that challenge the definition of molecular structure in quantum–mechanical terms. Instead of taking that top-down strategy, in this paper we face the problem (...) of the reduction of molecular structure to quantum mechanics from a bottom-up perspective: our aim is to show how the theoretical peculiarities of quantum mechanics stand against the possibility of molecular structure, defined in terms of the spatial relations of the nuclei conceived as individual localized objects. We will argue that, according to the theory, quantum “particles” are not individuals that can be identified as different from others and that can be reidentified through time; therefore, they do not have the ontological stability necessary to maintain the relations that can lead to a spatially definite system with an identifiable shape. On the other hand, although quantum chemists use the resources supplied by quantum mechanics with successful results, this does no mean reduction: their “approximations” add certain assumptions that are not justified in the context of quantum mechanics or are even inconsistent with the very formal structure of the theory.

Although during the last decades the philosophy of chemistry has greatly extended its thematic scope, the main difficulties appear in the attempt to link the chemical description of atoms and molecules and the description supplied by quantum mechanics. The aim of this paper is to analyze how the difficulties that threaten the continuous conceptual link between molecular chemistry and quantum mechanics can be overcome or, at least, moderated from the perspective of BM. With this purpose, in “The quantum-mechanical challenges” section (...) the foundational incompatibility between chemical and SQM descriptions will be briefly recalled. “Bohmian mechanics” section will be devoted to explain the main features of BM. In “Empirical equivalence and underdetermination” section, the consequences of the empirical equivalence between SQM and BM will be discussed. Finally, in the Conclusion, we will stress the scope of the obtained conclusions and the philosophical difficulties that still remain even after adopting BM for foundational purposes. (shrink)

El propósito de este texto es tematizar la precariedad con las herramientas de la filosofía política. Buscaremos equilibrar horizontes conceptuales con prácticas políticas para pensar la acción democrática en nuestro contexto. Nuestro argumento se compone de cuatro premisas. Primero, que elfalso dilema entre teoría y práctica nos permite explorar una relación de tensión creativa entre ambas para conceptualizar la precariedad. Segundo, que la construcción teórica de la precariedad responde tanto a ideas y conceptos como a instituciones y discursos que configuran (...) las vidas de quienes la experimentan. Tercero, que los distintos usos del concepto de precariedad permiten reconocer una fuente común de vulneración de derechos relacionada con la configuración del trabajo en el orden neoliberal. Cuarto, que relacionar la conceptualización de lo plebeyo con la de lo precario nos permite pensar prácticas democráticas renovadas. (shrink)

Este texto aborda la problemática relación entre verdad y palabra, específicamente aquello que hace que un enunciado tenga estatus de verdad. A partir de ciertas consideraciones históricas sobre el problema del dogmatismo teórico, se realiza una breve aproximación a distintas formas en las que el problema de la verdad ha estado presente en el pensamiento moderno. Para de este modo desarrollar el aporte específico del psicoanálisis sobre la materia, cuestión que atañe también al modo de concebir la clínica y la (...) misma teoría psicoanalítica. Finalmente, se sostiene que desde la perspectiva psicoanalítica es posible concebir de otro modo el problema de la verdad de los enunciados. (shrink)

Tácito fue uno de los escritores más reconocidos en los círculos intelectuales de la América revolucionaria. No se conservan muchas referencias explícitas en los escritos del periodo, pero su influencia es perceptible en los argumentos empleados para legitimar la independencia del Imperio británico. En el siguiente trabajo, se identificarán los elementos de la obra de Tácito que fueron recuperados por los padres fundadores durante la revolución. Las traducciones consultadas de clara ideología whig, modelaron la interpretación de la obra de Tácito (...) y su aplicación en la práctica política. Además, se analizará su empleo en el debate político de formas bien distintas, pero siempre por su utilidad en la construcción de la nueva república. (shrink)

Personal positions and voices of a patient diagnosed with borderline personality disorder and the therapist during long-term psychotherapy were studied aiming to find differences in the patterns formed in these aspects of subjectivity according to the level of elaboration of the change episodes achieved by the patient. This case study considered a stage of qualitative analysis where change episodes of the patient were traced through the Change Episodes Model. Later, through the Model of Analysis of Discursive Positioning in Psychotherapy, the (...) voices and personal positions of the patient and her therapist were identified in each of the change episodes. In the stage of quantitative analysis, dynamic patterns in the voices and personal positions were established, accounting for hypothetical attractors using the Space State Grid technique in each of the three different levels of subjective elaboration that constitute the change episodes. The results established differentiated dynamic patterns in the change episodes, coherent with the patient’s change process, and formation of propositive/reflective specific patterns as the patient evolved in the three different levels of subjective elaboration. The above suggests that a subjective transformation process is displayed, and this is manifested in the different voices and personal positions that emerged as the change episodes evolve. The identified dynamic patterns can be considered nonlinear and emergent subjective exchanges between the patient and the therapist throughout the psychotherapy. (shrink)

The concept of measuring inconsistency in information was developed by John Grant in a 1978 paper in the context of first-order logic. For more than 20 years very little was done in this area until in the early 2000s a number of AI researchers started to formulate new inconsistency measures primarily in the context of propositional logic knowledge bases. The aim of this volume is to survey what has been done so far, to expand inconsistency measurement to other formalisms, to (...) connect it with related topics, and to provide ideas for further research in a topic that is particularly relevant now in view of the many inconsistencies in the massive amount of information available. The book contains 11 chapters. The first chapter, by John Grant, gives his original motivation for starting this field, explains why it was formulated in a highly mathematical manner, presents important material that was omitted from the original paper, and provides ideas about the use of dimensions in measuring inconsistency. The second chapter, by Matthias Thimm, is a survey that covers most of the research on inconsistency measures up to 2017. The other 9 chapters, all by experts either in inconsistency measures, or in the topic under consideration, or both, connect inconsistency measures with argumentation, disjunctive logic programming, fuzzy logic systems, modal logics, multiset representation, paraconsistent consequence, probabilistic logic, relational databases, and spatio-temporal databases."-- back cover.

El fracaso político de la Revolución francesa deja un regusto amargo de que el problema del ser humano se encuentra en la Modernidad y, concretamente, en la escisión radical que abre la conciencia. Los ideales del Bien y la Verdad son señaladas como formas muertas, carentes de potencia erótica, inservibles para movilizar al ser y, por tanto, anacrónicos para una época que quiere despertar bajo el signo de la Belleza. Un joven Schelling escribe bajo este sol naciente una obra en (...) la que el arte aparece como una praxis capaz de suturar aquella herida que abre la conciencia. La imaginación y la síntesis poética son elementos ineludibles en el transitar por una vida humana que busca su plenitud en el retorno a la unidad originaria con lo Absoluto. El gesto del genio artístico será el privilegiado para este tránsito al origen. (shrink)

Apart from being one of the main and early receptors of Pragmatism, Miguel de Unamuno was particularly influenced by William James. The four books of the American philosopher that Unamuno read, Principles of Psychology, The Will to Believe, The Varieties of Religious Experience and Pragmatism, were a source of inspiration and influence in the development of Miguel de Unamuno’s thought.

Populism’s Challenges to Political Reason can be seen as a consequence of social and cultural trends, the so called ‘emotional culture’, that have been accentuated in recent decades. By considering those trends, this article aims at shedding light on some distinctive marks of contemporary populism in order to argue for a reconfiguration of the public sphere that, without ignoring emotion, recovers argumentation and persuasion based on facts and reason.

According to Robert Hertz, death means a change in social relations. The purpose of this paper is to inquire about the kind of mediation that different world populations establish with their deaths. We compared examples from different eras and regions, and three main strategies are identified which, even if they admit certain number of variations, can be characterized by the persistence of a common logic. These are: distance, in which identities and relations are modified; recycling, when identities are maintained but (...) relations are transformed; and retention, which accepts the transmutation of identities, but not of relations. Once described the qualities of each one, we show that, far from being able to identify any economic-social conditioning, these strategies can coexist as possibilities in the mind of every society.

Should CSR be approached only on a voluntary basis or should it be complemented with a compulsory regulatory framework? What type of government intervention is more effective in fostering CSR among companies? This paper is an attempt to answer these questions, reviewing the debate between proponents of the voluntary case and the obligatory case for CSR, and critically analysing current international government-led initiatives to foster CSR among companies, and national government-led initiatives in the EU area. Finally, the paper focuses on (...) the Spanish case, as an example of the failure of an exclusively voluntary approach. Despite the rapid uprise of CSR, Spain is still far behind late in CSR promotion strategies. Most action has been undertaken by companies themselves with no common guidelines, governmental support, or independent verification. The lack of a regulatory framework for CSR or ethical investment issues and the virtual absence of other indirect incentives, explains the misbalance between private, public and Third Sector initiatives. Based on the Spanish context which is quite similar to other non-OECD countries, the authors call for a more proactive government position in CSR related issues. The conclusions of the paper detail the features of this regulatory framework and other policies to promote CSR in Spain as well as in other OECD countries. (shrink)

This text proposes a conception of Richard Rorty’s philosophy from the distinction between systematic philosophy and edifying philosophy, proposing this distinction as a key to reading his neo-pragmatism and his political-ethical proposal of the 90s, whose consequence main will be his conception of liberal democracy, ironic citizen and post-philosophical culture.

Quantum chemistry is the branch of chemistry whose primary focus is the application of quantum mechanics to chemical systems at the molecular level. Precisely due to its peculiar position between chemistry and physics, in the last times it has begun to engage the interest of the philosophers of chemistry. Nevertheless, in this philosophical field, quantum chemistry has been studied mainly from a historical viewpoint or from a perspective interested on methodological issues. By contrast, the question that will guide this article (...) is: what kind of ontic items are those studied by quantum chemistry? In order to develop the argumentation, first the relevance of the ontological questions will be addressed. Then, it will be considered in what measure the Born-Oppenheimer approximation and the quantum-chemistry concept of electron fit in the quantum theoretical context. Finally, some issues about what quantum chemistry refers to will be discussed. (shrink)

An interpretation of quantum mechanics that rejects hidden variables has to say something about the way measurement can be understood as a transformation on states of individual systems, and that leads to the core of the interpretive problems posed by Luders' projection rule: What, if any, is its physical content? In this paper I explore one suggestion which is implicit in usual interpretations of the rule and show that this view does not stand on solid ground. In the process, important (...) aspects of the role played by the projection postulate in the conceptual structure of quantum mechanics will be clarified. It will be shown in particular that serious objections can be raised against the (often implicit) view that identifies the physical relation of compatibility preserved by Luders' rule with the relation of simultaneous measurability.

This study analyzes the logic behind the development of environmental responsiveness in companies that are located in geographical clusters. Drawing on previous research, we contend that competitiveness and legitimation are important sources of variation in these companies’ environmental responses. In particular, the companies’ perceived rivalry, competition tracking capabilities, interaction with industry associations and network embeddedness influence their competitiveness and legitimation motivations for environmental responsiveness. We used structural equation modeling to test these hypotheses on a sample of 251-clustered agricultural firms in (...) Spain. The results support the hypotheses and provide a number of insights about the underlying motivations behind going green in geographical clusters. (shrink)

Biomedical advances of the past 20 years have stimulated a renewed interest in medical ethics. Transplantation of multiple human organs, implantation of artificial devices, advances in genetics, and stem cell research are a few of the medical procedures and discoveries that have awakened in both professionals and the public an awareness that medical discoveries often raise important ethical and societal issues. Today, members of the medical profession face issues that did not seem so pressing to their predecessors, and physician conduct (...) in response to many of these issues involves decision-making based on ethical principles. Issues of informed consent, gifts from pharmaceutical companies, and patient rights to privacy were not of great concern to most physicians a generation ago. However, these and other topics that involve a physician's ethical conduct have become increasingly pertinent to the practice of medicine.A renewed emphasis on ethics has been voiced by leaders in the field of medicine.

Usual derivations of Lilders's projection rule show that Liuders's rule is the rule required by quantum statistics to calculate the final state after an ideal (minimally disturbing) measurement. These derivations are at best inconclusive, however, when it comes to interpreting Liuders's rule as a description of individual state transformations. In this paper, I show a natural way of deriving Liiders's rule from well-motivated and explicit physical assumptions referring to individual systems. This requires, however, the introduction of a concept of individual (...) state which is not standard. (shrink)

Récurrente sous différentes formes dans le domaine de la lexicométrie, l’analyse cooccurrentielle vise à dévoiler les attractions lexicales qui opèrent dans un texte en restituant un état intermédiaire entre la séquence textuelle et l’inventaire lexical, état qui doit combiner l’explicitation syntagmatique de l’une avec la hiérarchisation statistique de l’autre. Pour dépasser les résultats des méthodes de cooccurrence classiques et identifier des systèmes cooccurrentiels plus complexes à l’oeuvre dans le texte, il s’avère nécessaire de substituer à l’approche analytique des associations lexicales (...) une vue synthétique de ces attractions prééminentes en contexte.
