IntroductionCardiology is characterized by its state-of-the-art biomedical technology and the predominance of Evidence-Based Medicine. This predominance makes it difficult for healthcare professionals to deal with the ethical dilemmas that emerge in this subspecialty. This paper is a first endeavor to empirically investigate the axiological foundations of the healthcare professionals in a cardiology hospital. Our pilot study selected, as the target population, cardiology personnel not only because of their difficult ethical deliberations but also because of the stringent conditions in which they (...) have to make them. Therefore, there is an urgent need to reconsider clinical ethics and Value-Based Medicine. This study proposes a qualitative analysis of the values and the virtues of healthcare professionals in a cardiology hospital in order to establish how the former impact upon the medical and ethical decisions made by the latter.ResultsWe point out the need for strengthening the roles of healthcare personnel as educators and guidance counselors in order to meet the ends of medicine, as well as the need for an ethical discernment that is compatible with our results, namely, that the ethical values developed by healthcare professionals stem from their life history as well as their professional education.ConclusionWe establish the kind of actions, communication skills and empathy that are required to build a stronger patient-healthcare professional relationship, which at the same time improves prognosis, treatment efficiency and therapeutic adhesion.

The logicality of language is the hypothesis that the language system has access to a ‘natural’ logic that can identify and filter out as unacceptable expressions that have trivial meanings—that is, that are true/false in all possible worlds or situations in which they are defined. This hypothesis helps explain otherwise puzzling patterns concerning the distribution of various functional terms and phrases. Despite its promise, logicality vastly over-generates unacceptability assignments. Most solutions to this problem rest on specific stipulations about the properties (...) of logical form—roughly, the level of linguistic representation which feeds into the interpretation procedures—and have substantial implications for traditional philosophical disputes about the nature of language. Specifically, contextualism and semantic minimalism, construed as competing hypotheses about the nature and degree of context-sensitivity at the level of logical form, suggest different approaches to the over-generation problem. In this paper, I explore the implications of pairing logicality with various forms of contextualism and semantic minimalism. I argue that to adequately solve the over-generation problem, logicality should be implemented in a constrained contextualist framework. (shrink)

We present a mathematical approach to defeasible reasoning based on arguments. This approach integrates the notion of specificity introduced by Poole and the theory of warrant presented by Pollock. The main contribution of this paper is a precise, well-defined system which exhibits correct behavior when applied to the benchmark examples in the literature. It aims for usability rather than novelty. We prove that an order relation can be introduced among equivalence classes of arguments under the equi-specificity relation. We also prove (...) a theorem that ensures the termination of the process of finding the justified facts. Two more lemmas define a reduced search space for checking specificity. In order to implement the theoretical ideas, the language is restricted to Horn clauses for the evidential context. The language used to represent defeasible rules has been restricted in a similar way. The authors intend this work to unify the various existing approaches to argument-based defeasible reasoning.

The classification of ageing as a disease is fundamental to developing new pharmacological strategies that can target said phenomenon. The European Medicines Agency does not do this and maintains a questionable perspective based on the traditional naturalistic argument and the value-free ideal. An alternative is proposed which, inspired by consequentialism, is committed to considering ageing as a disease in European regulatory contexts as long as the ethical consequences are desirable. Within a realistic framework, I show that making this decision would (...) have moderate positive effects such as increased knowledge about antiageing pharmacology or potential greater chances of completing vital projects. Furthermore, we will see that the main arguments used by critics to show that the negative effects outweigh the positive ones are not sound. Therefore, I conclude that it would be beneficial for the European Medicines Agency to change its position on ageing. (shrink)

En los procesos de identificación social muchas veces la valoración del pasado resulta fundamental. La existencia objetiva de esa valoración ha propiciado que distintos actores sociales, en diferentes momentos históricos, hayan hecho uso del pasado en la estructuración de las ideologías que sustentan los procesos de identificación y, en consecuencia, sus propios proyectos políticos. Es decir, los mitos políticos están compuestos manifiestamente de dos componentes básicos. Por un lado, consisten en la así llamada política simbólica y por el otro lado, (...) son parte de la memoria colectiva. Es por esto que los mitos se enfrentan con las bases mismas del proyecto de modernidad, quizás la razón por la cual sea la politología la disciplina de las ciencias sociales que menos los ha estudiado. La utopía andina, el mahdi o el doceavo imán, el emperador alemán oculto y dormido y el bolivarianismo, constituyen algunos estos mitos políticos. (shrink)

Recent work in formal semantics suggests that the language system includes not only a structure building device, as standardly assumed, but also a natural deductive system which can determine when expressions have trivial truth-conditions (e.g., are logically true/false) and mark them as unacceptable. This hypothesis, called the `logicality of language', accounts for many acceptability patterns, including systematic restrictions on the distribution of quantifiers. To deal with apparent counter-examples consisting of acceptable tautologies and contradictions, the logicality of language is often paired (...) with an additional assumption according to which logical forms are radically underspecified: i.e., the language system can see functional terms but is `blind' to open class terms to the extent that different tokens of the same term are treated as if independent. This conception of logical form has profound implications: it suggests an extreme version of the modularity of language, and can only be paired with non-classical---indeed quite exotic---kinds of deductive systems. The aim of this paper is to show that we can pair the logicality of language with a different and ultimately more traditional account of logical form. This framework accounts for the basic acceptability patterns which motivated the logicality of language, can explain why some tautologies and contradictions are acceptable, and makes better predictions in key cases. As a result, we can pursue versions of the logicality of language in frameworks compatible with the view that the language system is not radically modular vis-a-vis its open class terms and employs a deductive system that is basically classical.

Bi-intuitionistic logic is the result of adding the dual of intuitionistic implication to intuitionistic logic. In this note, we characterize the expressive power of this logic by showing that the first order formulas equivalent to translations of bi-intuitionistic propositional formulas are exactly those preserved under bi-intuitionistic directed bisimulations. The proof technique is originally due to Lindstrom and, in contrast to the most common proofs of this kind of result, it does not use the machinery of neither saturated models nor elementary (...) chains.

Seventeen essays make up the body of this anthology. Most of the authors are Latin Americans (although some of them work in other regions), and thus we might say that this volume is, in a very approximate sense, a showcase of recent Latin-American ontology and metaphysics. The remaining authors—Pierre Aubenque, Barry Smith, Lorenzo Peña and James Hamilton—are distinguished teachers who have had important contacts with the Latin-American philosophical community. The articles in this anthology address some of the central questions in (...) ontology and metaphysics: the possibility of a science of being (Aubenque), the different possible approaches to ontology (Hurtado), the recent application of ontology to informatics (Smith), guise theory and its Leibnizian antecedents (Herrera), the reduction of space and time to phenomenological properties (Rodríguez Larreta), the Newtonian ontology of space and time (Benítez and Robles), the relation between truth and the so-called “truth-makers” (Rodríguez Pereyra), the ontological position of the Pyrrhonic skeptic (Junqueira Smith), the limits and difficulties of metaphysical realism (Cabanchik, Pereda), the defense of physicalist or emergentist positions regarding the mental (Pérez), the metaphysical nature of persons (Naishtat), the ontology of cultural entities (Peña), political ontology (Nudler), the relation between ontology and literature (Hamilton), the ontology of art (Tomasini). Some of the works (e.g., those Aubenque and Robles) approach the question from a historical perspective: others examine the most recent philosophical literature on the problems focalized (e.g., those by Pérez and Rodríguez Pereyra), and others offer new approaches (e.g., those of Rodríguez Larreta, Peña or Nudler) to a specific problematic area.

Lindström’s theorem obviously fails as a characterization of first-order logic without identity ( $\mathcal {L}_{\omega \omega }^{-} $ ). In this note, we provide a fix: we show that $\mathcal {L}_{\omega \omega }^{-} $ is a maximal abstract logic satisfying a weak form of the isomorphism property (suitable for identity-free languages and studied in [11]), the Löwenheim–Skolem property, and compactness. Furthermore, we show that compactness can be replaced by being recursively enumerable for validity under certain conditions. In the proofs, we (...) use a form of strong upwards Löwenheim–Skolem theorem not available in the framework with identity. (shrink)

This paper is a step toward showing what is achievable using non-classical metatheory—particularly, a substructural paraconsistent framework. What standard results, or analogues thereof, from the classical metatheory of first order logic can be obtained? We reconstruct some of the originals proofs for Completeness, Löwenheim-Skolem and Compactness theorems in the context of a substructural logic with the naive comprehension schema. The main result is that paraconsistent metatheory can ‘re-capture’ versions of standard theorems, given suitable restrictions and background assumptions; but the shift (...) to non-classical logic may recast the meanings of these apparently ‘absolute’ theorems.

This paper is devoted to the problem of existence of saturated models for first-order many-valued logics. We consider a general notion of type as pairs of sets of formulas in one free variable that express properties that an element of a model should, respectively, satisfy and falsify. By means of an elementary chains construction, we prove that each model can be elementarily extended to a $\kappa $-saturated model, i.e. a model where as many types as possible are realized. In order (...) to prove this theorem we obtain, as by-products, some results on tableaux and their consistency and satisfiability and a generalization of the Tarski–Vaught theorem on unions of elementary chains. Finally, we provide a structural characterization of $\kappa $-saturation in terms of the completion of a diagram representing a certain configuration of models and mappings. (shrink)

Under a proper translation, the languages of propositional (and quantified relevant logic) with an absurdity constant are characterized as the fragments of first order logic preserved under (world-object) relevant directed bisimulations. Furthermore, the properties of pointed models axiomatizable by sets of propositional relevant formulas have a purely algebraic characterization. Finally, a form of the interpolation property holds for the relevant fragment of first order logic.

This book considers the seminal debate in jurisprudence between Ronald Dworkin and Stanley Fish. It looks at the exchange between Dworkin and Fish, initiated in the 1980s, and analyses the role the exchange has played in the development of contemporary theories of interpretation, legal reasoning, and the nature of law. The book encompasses 4 key themes of the debate between these authors: legal theory and its critical role, interpretation and critical constraints, pragmatism and interpretive communities, and some general implications of (...) the debate for issues like the nature of legal theory and the possibility of objectivity. The collection brings together prominent legal theorists and one of the protagonists of the debate: Professor Stanley Fish, who concludes the collection with an interview in which he discusses the main topics discussed in the collection.

This edited collection includes contributions from expert philosophers of law and considers the work of one of the most important legal philosophers of our time, Professor Gerald J Postema. The chapters dig deep into important camps of Postema's rich theoretical project including: - the value of the rule of law; - the ideal of integrity in adjudication; - his works on analogical reasoning; - the methodology of jurisprudence; - dialogues with Ronald Dworkin, Joseph Raz, Frederick Schauer and HLA Hart. It (...) includes an original article by Professor Postema, in which he develops his conception of the rule of law and replies to some objections to previous works, and an interview in which he provides a fascinating and unique insight into his philosophy of law.

We show that propositional intuitionistic logic is the maximal abstract logic satisfying a certain form of compactness, the Tarski union property, and preservation under asimulations.

Benjamin’s Critique of Violence (1921) has been a relevant source of legal and political philosophy about the nature of law, from Derrida to Menke. In this article, we rebuild the reading of Benjamin’s Critique proposed by Menke and consider the appropriateness of violence in the law not as a tragic tension, but as a condition for its reproduction. Finally, we will consider its paradoxical nature as a confirmation of the difference between the force of law and social-normative elements such as (...) recognition [ Anerkennung]. (shrink)

Se examina la noción de espectro, propuesta en Espectros de Marx, para evidenciar la problematización que Jacques Derrida hace a la oposición, que se supone tajante, entre las nociones de vida y muerte. Se evidencia que Derrida no traza tal problematización exclusivamente a partir de Espectros de Marx, sino también desde diversos textos que dan cuenta de un constante asedio que ronda su pensamiento: la sobrevida. A su vez, se analiza la discusión que Derrida sostuvo con el espectro de Marx (...) para evidenciar: (1) de qué modo la herencia fiel-infiel de Marx contribuye al pensamiento de la sobrevida; (2) cómo en tal pensamiento de la sobrevida se inscribe necesariamente el problema de la justicia y la alteridad.

O artigo – desde uma perspectiva da educação como direito humano universal que reconhece a diversidade – realiza um recorrido panorâmico por uma série de dimensões da educação intercultural no ensino superior do Chile, especialmente universitária, discute criticamente a situação atual da interculturalização na universidade – entendida genericamente – e conclui com algumas perguntas que podem orientar pesquisas ou decisões que levem a que o ensino superior considere os direitos indígenas, permita a expressão de sua cultura, promova a interculturalidade, forme (...) os técnicos e profissionais que requerem o desenvolvimento da sociedade e das comunidades e enriqueça a docência e a ciência com outros paradigmas de conhecimento. Desse modo, que reconheça e valide a interculturalidade e os aportes das culturas indígenas a sua identidade, formação e produção de conhecimento. Trata das comunidades e dos estudantes indígenas em geral, mas aprofunda a situação desde o povo mapuche, embasando-se em projetos de pesquisa e desenvolvimento e em experiências em e desde a Região da Araucanía. A proposta se centra na ideia de que o direito à educação, desde a lei e inconstitucionalidade atual, se centra no sistema escolar formal de ensino básico e médio e não considera a educação superior ou a um sistema de educação continuado como direito universal, no qual poderia se especificar uma condição especial aos estudantes indígenas. Por isso, hoje se luta pela igualdade de oportunidades de inclusão entre indígenas e não indígenas. Palavras-chave: Ensino Superior. Interculturalidade. Cultura mapuche. (shrink)

We generalize the notion ofconsequence relationstandard in abstract treatments of logic to accommodate intuitions ofrelevance. The guiding idea follows theuse criterion, according to which in order for some premises to have some conclusion(s) as consequence(s), the premises must each beusedin some way to obtain the conclusion(s). This relevance intuition turns out to require not just a failure of monotonicity, but also a move to considering consequence relations as obtaining betweenmultisets. We motivate and state basic definitions of relevant consequence relations, both (...) in single conclusion (asymmetric) and multiple conclusion (symmetric) settings, as well as derivations and theories, guided by the use intuitions, and prove a number of results indicating that the definitions capture the desired results (at least in many cases).

We provide a sucient frame-theoretic condition for a super bi-intuitionistic logic to have Maksimova's variable separation property. We conclude that bi-intuitionistic logic enjoys the property. Furthermore, we offer an algebraic characterization of the super-bi-intuitionistic logics with Maksimova's property.

In this note we study a counterpart in predicate logic of the notion of logical friendliness, introduced into propositional logic in [15]. The result is a new consequence relation for predicate languages with equality using first-order models. While compactness, interpolation and axiomatizability fail dramatically, several other properties are preserved from the propositional case. Divergence is diminished when the language does not contain equality with its standard interpretation.

En el presente trabajo examinaremos la relevancia de la categoría de decisión en el surgimiento del pensamiento impolítico contemporáneo en Italia. Con este objetivo, buscaremos elaborar una exégesis del rol de dicha noción en los desarrollos de Massimo Cacciari de finales de la década de 1970. Nuestro punto de partida se encontrará en su lectura nietzscheana sobre el diagnóstico de crisis de las categorías metafísicas y políticas tradicionales. Tal interpretación nos conducirá a estudiar su análisis de la soberanía desde una (...) “concepción criatural” del orden político. En este sentido, sostendremos que la crítica que Cacciari realiza al concepto de decisión no sólo vertebra desde sus inicios al horizonte impolítico, sino que también nos permite comprender los alcances filosóficos de su perspectiva.
