A previous article, published in GREGORIANUM 2000, pp. 249ff, has treated Zubiri's concept of the Eucharist. The present article proposes to expose, by way of complement, the reflections of the same author on the general concept of the sacrements. For sure, these reflections are those of a philosopher on a theological theme. Under one aspect, this may indicate a limitation. Yet, the author of the article thinks that, starting from his philosophical presuppositions, Zubiri contributes a notable enrichment for the theology (...) of the sacraments. Zubiri centres his attention on the actuality of the death and resurrection of Christ in the celebration of the sacrements, deepening some concrete points such as the christological dimension, the nature of «efficacy» and the concept of grace. The author thinks that with his reflections on the sacraments in general Zubiri offers fundamental and valid elements for an adequate renewal of the theology of the sacraments. (shrink)

Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)

For this issue of JBE, Zyphur and Pierides :1–16, 2017) have written a paper on a concept that they have labeled relational validity. The purpose of the paper and of their advocacy for the concept of relational validity is to improve the way that quantitative research is done by expanding our understanding of its ethics-laden aspects. I agree entirely with the authors that every decision regarding QR is an ethics-laden one and that our research as a whole would be improved (...) by recognition of this fact. I disagree with the authors regarding some of the ways that this improvement might be brought about. (shrink)

Łukasiewicz presented two different analyses of modal notions by means of many-valued logics: the linearly ordered systems Ł3,..., Open image in new window,..., \; the 4-valued logic Ł he defined in the last years of his career. Unfortunately, all these systems contain “Łukasiewicz type paradoxes”. On the other hand, Brady’s 4-valued logic BN4 is the basic 4-valued bilattice logic. The aim of this paper is to show that BN4 can be strengthened with modal operators following Łukasiewicz’s strategy for defining truth-functional (...) modal logics. The systems we define lack “Łukasiewicz type paradoxes”. Following Brady, we endow them with Belnap–Dunn type bivalent semantics. (shrink)

Suppose that we are interested in the average causal effect of a binary treatment on an outcome when this relationship is confounded by a binary confounder. Suppose that the confounder is unobserved but a nondifferential proxy of it is observed. We show that, under certain monotonicity assumption that is empirically verifiable, adjusting for the proxy produces a measure of the effect that is between the unadjusted and the true measures.

Tarski's 1936 paper, “On the concept of logical consequence”, is a rather philosophical, non-technical paper that leaves room for conflicting interpretations. My purpose is to review some important issues that explicitly or implicitly constitute its themes. My discussion contains four sections: terminological and conceptual preliminaries, Tarski's definition of the concept of logical consequence, Tarski's discussion of omega-incomplete theories, and concluding remarks concerning the kind of conception that Tarski's definition was intended to explicate. The third section involves subsidiary issues, such as (...) Tarski's discussion concerning the distinction between material and formal consequence and the important question ofthe criterion for distinguishing between logical and non-logical terms.§1. Preliminaries. In this paper an argument is a two-part system composed of a set of propositions P and a single proposition c. The expression ‘c is a [logical] consequence of P’ is used with the same meaning as the expression ‘c is [logically] implied by P’. The expressions ‘is a logical consequence of’ and the converse ‘implies’ are relational. Often, I shall be talking in the same sense of validity of an argument. Validity is a property of arguments; an argument with premise-set P and conclusion c is valid if and only if P implies c; i.e., c is a logical consequence of P. Notice that this notion of argument is strictly ontic; it does not involve any agent that thinks, determines or establishes that a given proposition is or is not a consequence of a given set of propositions.

Going from cognitive theory to neural data to ACT‐R models, the authors relate brain activity in a lexical ambiguity priming task to brain processes that resolve ambiguity in word meanings. These detailed data were tested and found compatible to the results of an ACT‐R computational model of reinforcement learning (RL). The model confirms and extends the behavioral findings to provide a RL account of individual differences in lexical ambiguity resolution.

Let R+ be the positive fragment of Anderson and Belnap’s Logic of Relevance, R. And let RMO+ be the result of adding the Mingle principle ) to R+. We have shown in [2] that either a minimal negation or else a semiclassical one can be added to RMO+ preserving the variable-sharing property. Moreover, each of there systems is given a semantics in the Routley-Meyer style. In describing in [2] the models for RMO+ plus minimal negation, we noted that a similar (...) strategy would give us a semantics for R+ with minimal negation; that is, constructive R. The aim of this paper is to prove this claim. (shrink)

In this article, we propose a philosophical exploration on the main problems involved in two neurorights that concern autonomous action, namely free will and cognitive liberty, and sketch a possible solution to these problems by resourcing to a holistic interpretation of human actions. First, we expose the main conceptual and practical issues arising from the neuroright to “free will,” which are far from minor: the term itself is denied by some trends participating in the neurorights debate, the related concept of (...) ultimate control is also disputed, the understanding of free will depends on cultural context, and the exercise of being free to act in several domains may be covered by other regulations. Second, we analyze the historical origin of cognitive liberty, its current status, and its relation with free will. Third, we criticize the concept of decision in mainstream action theory and propose to conceive action as a unified process constituted by three explanatory, non-sequential dimensions: intention, decision, and action realization. Fourth, we discuss two possible cases involving neurotechnologies and suggest ways to interpret them according to a unified framework in which free will and cognitive liberty fall under a single neuroright to personal autonomy. Finally, we outline a recommendation to introduce freedom of thought and personal autonomy as complementary neurorights to protect both the internal and external dimensions of thought and action.

This paper offers a particular intuitionistic negation completion of Urquhart's system C resulting in a super-intuitionistic contractionless propositional logic equivalent to Dummett's LC without contraction.

A simple, bivalent semantics is defined for Łukasiewicz’s 4-valued modal logic Łm4. It is shown that according to this semantics, the essential presupposition underlying Łm4 is the following: A is a theorem iff A is true conforming to both the reductionist and possibilist theses defined as follows: rt: the value of modal formulas is equivalent to the value of their respective argument iff A is true, etc.); pt: everything is possible. This presupposition highlights and explains all oddities arising in Łm4.

This article discusses two coextensive concepts of logical consequence that are implicit in the two fundamental logical practices of establishing validity and invalidity for premise-conclusion arguments. The premises and conclusion of an argument have information content (they ?say? something), and they have subject matter (they are ?about? something). The asymmetry between establishing validity and establishing invalidity has long been noted: validity is established through an information-processing procedure exhibiting a step-by-step deduction of the conclusion from the premise-set. Invalidity is established by (...) exhibiting a countermodel satisfying the premises but not the conclusion. The process of establishing validity focuses on information content; the process of establishing invalidity focuses on subject matter. Corcoran's information-theoretic concept of logical consequence corresponds to the former. Tarski's model-theoretic concept of logical consequence formulated in his famous 1936 no-countermodels definition corresponds to the latter. Both are found to be indispensable for understanding the rationale of the deductive method and each complements the other. This study discusses the ontic question of the nature of logical consequence and the epistemic question of the human capabilities presupposed by practical applications of these two concepts as they make validity and invalidity accessible to human knowledge.

The aim of this paper is to define the logical system Sm4 characterised by the degree of truth-preserving consequence relation defined on the ordered set of values of Smiley’s four-element matrix MSm4. The matrix MSm4 has been of considerable importance in the development of relevant logics and it is at the origin of bilattice logics. It will be shown that Sm4 is a most interesting paraconsistent logic which encloses a sound theory of logical necessity similar to that of Anderson and (...) Belnap’s logic of entailment E. Intuitively, Sm4 can be described as a four-valued expansion of the positive fragment of Lewis’ S5 or, alternatively, as a four-valued version of S5. (shrink)

La existencia de evidentes semejanzas en cuestiones concretas entre las concepciones históricas y, sobre todo, entre algunos principios de la Muqaddimah de Ibn Jaldún y la Scienza Nuova de Vico, inducen a una puesta en confrontación de las principales ideas históricas de ambos pensadores. Considerando la distancia temporal de cuatro siglos entre el historiador magrebí y el filósofo napolitano, así como sus diferentes ámbitos culturales, se apuntan una serie de afinidades y de contrastes.The existence of plain resemblances on specific questions (...) between historical conceptions and more specially between some of the principles of Ibn Jaldún’s Muqaddimah and Vico’s Scienza Nuova might lead us to confront the two thinkers’ main conceptions. Taking into account both the four century temporal distance between the North-african thinker and the Neapolitan philosopher and the different background, there is an attempt to sketch a series of affinities and contrasts.

Vico otorga a la fantasia un doble papel: creador y expresivo y reconocedor y reconstructivo , que tiene su significación viquiana en los "caracteres poéticos" y en la consideración de "naturaleza poética" del hombre primitivo, además, en su segundo sentido, en el carácter que posee la imaginación como "llave" de la misma Scienza nuova. En trabajos anteriormente publicados por el autor ya han sido desarrollados aspectos concretos de esta cuestión, destacando su importancia tanto para el pensamiento viquiano como para las (...) ciencias humanas. En el presente trabajo se considera la cuestión de la "fantasía" articulando las más interesantes perspectivas desde las que se ha revalorizado el tema .Vico confers on "fantasia" a double role: creating and expresing and recognising and reconstructing , which has its Vichian significance in the "poetic characters" and in the consideration of the "poetic nature" of primitive man, and furthermore, in a second sense in the characteristics that imagination possesses as a "Key" to the Scienza nuova itself. Concrete aspects of this question have been already developed by the author in earlier published works, emphasising its importance as much for Vichian thought as for the Human Sciences. In this present work the question of "fantasia" is considered, bringing together the most interesting perspectives through wich this topic has been re-evaluated. (shrink)

El cristianismo, obligado por la Modernidad, tuvo que hacer un desplazamiento desde el plano dogmático al plano moral; hoy estamos ante otro desplazamiento: el que va desde el terreno moral al místico. En este terreno dominará sobre todo la experiencia personal de la presencia salvífica de Dios en Cristo. Esa experiencia, vivida en medio del pluralismo, consistirá en una síntesis activa entre la Presencia y su interpretación . Este ensayo trata de diseccionar las dimensiones existenciales y lingüísticas de esa síntesis. (...) Después de ver por qué somos pobres en experiencia, se analizan los componentes y caracteres esenciales de toda experiencia religiosa A continuación se disecciona la estructura simbólica de esta experiencia , y su configuración mítico-narrativa Palabras clave: 'Hermenéutica de los símbolos'; 'Mitos'; 'Mundos ficcionales'; 'Hermenéutica narrativa'; 'Mundo del texto'; 'Apropiación del sentido'.Christianity forced by modernity had to make a shift from a dogmatic plane to a moral one; today, there is another shift which goes from a moral to a mystical ground. The personal experience of God’s saving presence in Christ will dominate, over all, in this field. That experience, lived in the midst of pluralism will consist of an active synthesis between the presence and its interpretation .This essay intends to dissect the linguistic and existential dimensions of this synthesis. After seeing why we are poor in experience, we will analyze the essential components and characteristics of the religious experience , and its mythical narrative configuration. (shrink)

A marked feature of eukaryotic programmed cell death is an early drop in mitochondrial transmembrane potential. This results from the opening of permeability transition pores, which are composed of adenine nucleotide translocators and mitochondrial porins. The latter share striking similarites with bacterial porins, (including down‐regulation of their pore size by purine nucleotides), suggesting a common origin. The porins of some invasive bacteria play a crucial role during their accommodation inside the host cell and this co‐existence resembles the endosymbiotic origin of (...) mitochondria. The above observations suggest that early in eukaryotic evolution, former invaders may have used porin‐type channels to enter their host and to induce its death when the levels of its cytoplasmic purine nucleotides were dropped. The appearance of adenosine nucleotide translocators in the primitive eukaryotes, which permitted usage of the oxidative metabolism of the invaders, provided the basis for the permeability transition phenomena, now linked to the apoptotic process. Bcl‐2‐type molecules, being able to modulate the permeability transition pores by interaction with adenosine nucleotide translocators, may have played an essential role in conferring a means of controlling apoptosis.
