El presente estudio se propone iluminar la recepción de la exhortación apostólica Amoris laetitia. Para ello se toma como hilo conductor los tres verbos que aparecen en el capítulo VIII de la misma: acompañar, integrar y discernir, teniendo presente el conjunto de la exhortación. Siguiendo de cerca el vademécum escrito por tres profesores de la sede central del Instituto Teológico Juan Pablo II, consideramos sucesivamente el significado del acompañamiento, la integración y el discernimiento para la pastoral familiar. En el (...) acompañar nos detenemos en el acompañamiento de novios en su preparación próxima, en el acompañamiento de los primeros años de matrimonio, y en el acompañamiento de situaciones difíciles, como tres aspectos singularmente importantes hoy. El retorno a la comunión plena en la Iglesia es el objetivo del camino de la integración que tiene como sujeto a la entera comunidad cristiana. Finalmente, discernir no quiere decir discernir sobre el estado de gracia de una persona, cosa que únicamente le corresponde a Dios, sino que el objeto del discernimiento es triple: el deseo, el vínculo matrimonial y los pasos concretos.

Este volumen estudia el papel de Cristo en el dinamismo teológico de la acción. Lo hace a través de un análisis de los comentarios al Nuevo Testamento de Santo Tomás de Aquino. Con ello se pretende contribuir a la elaboración de un cristocentrismo moral dentro del proceso de renovación de la teología moral que se ha llevado a cabo en todo el siglo XX.

We argue that if evidence were knowledge, then there wouldn’t be any Gettier cases, and justification would fail to be closed in egregious ways. But there are Gettier cases, and justification does not fail to be close in egregious ways. Therefore, evidence isn’t knowledge.

In this volume, scientists, historians, and philosophers join to examine computer simulations in scientific practice. One central aim of the volume is to provide a multiperspective view on the topic. Therefore, the text includes philosophical studies on computer simulations, as well as case studies from simulation practice, and historical studies of the evolution of simulations as a research method.

Model organisms are at the centre of progress in biology but attributing them an excessive representational power and concentrating on a limited group of them, although efficient for research, can have negative consequences, mainly of epistemic nature. Here, I argue that model organisms are exploratory models with a perspectival modelling function, and that a deflated representational power is needed for their proper use. In support of this argument, I will analyse developmental biology as a case study. Firstly, I show that (...) model organisms in developmental biology are not selected because of their representational capabilities, but mainly based on practical criteria. Secondly, I defend that the epistemic organization of developmental biology around questions fosters exploration and perspectival modelling and I propose that developmental biology is a ‘model organism situated knowledge’. Lastly, I use the study of the mechanisms of cell fate acquisition during early embryonic development in _C. elegans_ and mice as a case study to illustrate how a plurality of model organisms allows exploration and perspectival modelling. The use of model organisms for exploration and perspectival modelling, with a limited representational power, should allow more adequate inferences about human embryonic development and encourage the introduction of more model organisms for a comprehensive navigation of the space of possibilities.

This paper regards Leonardo Polo’s motivation for his proposal of a new method in metaphysics, the science of being. It is presented a brief comparison with similar motivations in the area of Thomistic thought. The three main points of the proposal are: the problem of the mental limit, the notion of habitual knowledge, the distinction between metaphysics and the transcendental anthropology.

This paper presents current trends in philosophy of mind and philosophy of neuroscience, with a special focus on neuroscientists dealing with some topics usually discussed by philosophers of mind. The aim is to detect the philosophical views of those scientists, such as Eccles, Gazzaniga, Damasio, Changeux, and others, which are not easy to classify according to the standard divisions of dualism, functionalism, emergentism, and others. As the variety of opinions in these fields is sometimes a source of confusion, it is (...) worth the effort to obtain an overall panorama of the topic. A general conclusion on epistemological and ontological issues, concerning the relationship between neurobiology and philosophy and the multi-level account of the embodied mind, is proposed.

En este trabajo presento un estudio sobre el estado del arte de la llamada ‘epistemología de las simulaciones computacionales’. En particular, me centro en los varios trabajos de Eric Winsberg quién es uno de los filósofos más fructíferos y sistemáticos en este tema. Además de analizar la obra de Winsberg, y basándome en sus trabajos y en el de otros filósofos, mostraré que hay buenas razones para pensar que la epistemología tradicional de la ciencia no es suficiente para el análisis (...) de las simulaciones computacionales.

The coming to office of Jair Bolsonaro in Brazil has brought to the fore the need to understand the rise of the far right and to come to terms with the conflicted legacies of more than a decade of rule under the Workers’ Party. This forum brings together six leading intellectuals from different traditions on the left and introduces their reflections on the contradictions and complexities of the Workers’ Party, the 2008 crisis, the June 2013 protests, the weakness of the (...) Brazilian left, corruption, and on how to characterise Bolsonaro’s regime. Their interventions offer crucial insights that are relevant today not just to Brazil, or even Latin America, but to the politics of the left worldwide. (shrink)

The Adoption Problem (AP) was a postponed issue for some years (Kripke, 2024; Padró, 2015; Birman, 2024). This problem highlights certain difficulties surrounding the adoption of rules of inference: If anti-exceptionalism is wrong, is it possible to adopt an alternative logic? What is the point of the revision of logic in epistemology? During 2022 Kripke, Padró and Barrio held seminars on AP. The latter two edited the first thematic section on this subject in the journal Análisis Filosófico. It contains “What (...) the Adoption Problem Does Not Show” by Camilo Fiore, subject of this critical note, in which Fiore holds two theses: 1) AP is compatible with the thesis that logica utens is revisable; 2) to assess whether an agent can revise their logic, it is best to consider a different definition of adoption, e.g. weak adoption, according to which Universal Instantiation and Modus Ponens are sometimes adoptable. It then states that (1) and (2) are independent. In this article I will criticize the independence between (1) and (2). To this end, I will point out that thesis (1) and (2) are supported by the examples of Carrie and Barry, respectively, and that the type of logical revision involved in both is the same and local. Therefore, (1) and (2) are not independent. Next, I argue that it is impossible to satisfy another kind of logical revision, e.g. global revision. Therefore, the interdependence between (1) and (2) is not due to the examples proposed. (shrink)

This paper considers the relevance of the theory of the cogitative power in Aquinas, as highlighted by Cornelio Fabro during his early research in the fourth decade of the past century, in contemporary neuropsychological studies, and particularly as a specific way of overcoming a dualistic approach in the psychology of perception. The thesis is coherent with an anthropological view based on the substantial unity between soul and body. As a consequence, the capacities of the cogitative faculty (estimative in animals) involve (...) a special account of perception, irreducible to pure thought and to sensations as well, an account that is present in the psychological view of M. Merleau-Ponty and J. J. Gibson. (shrink)

En este trabajo me propongo mostrar las dificultades de sostener la argumentación de Raz para fundamentar los derechos colectivos en el caso de sociedades multiculturales. Para ello contrasto la argumentación de este autor con la de J. Griffin. Concluyo que si bien existen bienes comunales, en el caso de las sociedades multiculturales la imposibilidad de que estas actúen como unidad de agencia hace muy difícil un acuerdo sobre ellos y, en el caso de existir este acuerdo, el resultado no puede (...) llamarse «derecho» según la teoría del derecho defendida por Joseph Raz.

Schrödinger’s equation says that the Hamiltonian is the generator of time translations. This seems to imply that any reasonable definition of time operator must be conjugate to the Hamiltonian. Then both time and energy must have the same spectrum since conjugate operators are unitarily equivalent. Clearly this is not always true: normal Hamiltonians have lower bounded spectrum and often only have discrete eigenvalues, whereas we typically desire that time can take any real value. Pauli concluded that constructing a general a (...) time operator is impossible. Here we show how the Pauli argument fails when one uses an external system to track time, so that time arises as correlations between the system and the clock. In this case, the time operator is conjugate to the clock Hamiltonian and not to the system Hamiltonian, but its eigenvalues still satisfy the Schrödinger equation for arbitrary system Hamiltonians.

Polo’s theory on negation and the hypothetical intentionality of second determinations. These are usually understood as facticities. Moreover, such a theory can explain the internal relationship between facta and wide-ranging ideas. The formulation of this theory has to argue against a number of idealistic and nominalistic apories above the quantification in modal contexts and the clarity of concepts.

Levinas does not speak quite often about the Temple, but in his Talmudic commentaries, he says quite impressive things about the Temple and its image. Commenting the Tractate Yoma 10a of Talmud, he says that «The Temple of Jerusalem in Jewish thought is a symbol, which signifies for the whole of humanity». This paper focuses on clarify this sentence and the universality of one Temple, which «is an exact replica of the heavenly Temple, the order of absolute holiness» according with (...) his comment to Rabbi Hayyim Volozhiner. I research the symbolic value of the Temple in Jerusalem built as in ruins and try to connect this value with the rest of Levinas’ philosophy, especially with his theory of sacrifice as substitution.Palabras clave: Temple of Jerusalem; Politics-Messianism; History; Responsibility; Guilt; Holiness; Sacrifice.

Se abordan en este trabajo el desciframiento de un símbolo (de la physis) y una experiencia intelectual (la de eternidad). La metodología propuesta consiste en no tirar de la escalera (Wittgenstein), esto es señalando el carácter de visión siempre acompañada de enigma, y nunca totalizable objetivamente de los símbolos. En este sentido la tematización, interpretación y desciframiento de los símbolos es densa (Clifford Geertz). Se sitúa, asimismo, la filosofía poliana acerca de los conocimientos más altos de la esencia del hombre, (...) en el terreno de las modernas antropologías simbólicas. Y por último se señala la crítica poliana al ideal moderno de autoconciencia. (shrink)

During the sixties, a most curious symbiosis took hold between Heinz von Foerster then the Director of a top-notch and lavishly funded US laboratory [Biological Computer Laboratory, 1958–1975] and the Chilean neuroscientist Humberto R. Maturana professor at the Universidad de Chile. The chance encounter between them triggered a long-lasting friendship and a fundamental change in our understanding of Systems Science. In particular the contributions of Biology of Cognition and Autopoiesis are important to understand this change and the years 1968–1973 are (...) particularly relevant. In this period, Maturana published, as a Technical Report of BCL, the foundational document The Neurophysiology of Cognition. Later, in 1973, the book De Maquinas y Seres Vivos put forward the notion of Autopoietic Systems. Also, between 1971 and 1973, the Allende government tried to cybernitize the Chilean economy with the SYNCO project. In that project, Maturana and von Foerster played a role by teaching Cybernetics to the engineers and administrators of this technological dream. During this same time, Cybernetics was important in Chile and Professors Maturana and von Foerster although not directly involved in the day-to-day running of SYNCO were important in that unique effort. When a military coup deposed Allende and sent Chile into a tailspin of right-wing retribution, von Foerster, a foreigner who loved Chile and its people, did his outmost to assure the safety of many people involved in this unique Latin American Cybernetics dream.

En esta voz se considera el tiempo como una dimensión de la realidad física que se manifiesta en la percepción de las cosas en su devenir y cuya realidad ontológica se apoya en las transformaciones naturales. Primeramente se afronta la temática del tiempo físico y sus características en una perspectiva filosófica. Se tocan cuestiones fundamentales como el estatuto ontológico del presente/pasado/futuro, la realidad o irrealidad del instante, la simultaneidad, la unidad y pluralidad de tiempos, la dirección temporal (flecha irreversible del (...) tiempo) y la relación entre tiempo y causalidad. Se distingue entre tiempo natural, tiempo fenomenológico (percepción humana del tiempo) y tiempo métrico (medidas humanas temporales). En segundo término, se estudia la conceptualización científica de la temporalidad, con cuestiones ontológicas como, por ejemplo, la posibilidad o no de los viajes en el tiempo, la temática del tiempo absoluto o relativo, y la cuestión del inicio y final del tiempo cosmológico. En tercer lugar, se considera la temporalidad tal como se manifiesta en la vida humana en forma de historicidad, así como la trascendencia del espíritu humano sobre el tiempo, con un vínculo especial con la eternidad. En cuarto y último lugar, se estudia la temporalidad a la luz de la teología bíblica, donde el tiempo cósmico e histórico quedan transfigurados en el tiempo salvífico, estableciéndose así una relación especial con la vida eterna de Dios, de la que el hombre, en el Cristianismo, se hace partícipe a través de Cristo.

The volume gathers theoretical contributions on human rights and global justice in the context of international migration. It addresses the need to reconsider human rights and the theories of justice in connection with the transformation of the social frames of reference that international migrations foster. The main goal of this collective volume is to analyze and propose principles of justice that serve to address two main challenges connected to international migrations that are analytically differentiable although inextricably linked in normative terms: (...) to better distribute the finite resources of the planet among all its inhabitants; and to ensure the recognition of human rights in current migration policies. Due to the very nature of the debate on global justice and the implementation of human rights and migration policies, this interdisciplinary volume aims at transcending the academic sphere and appeals to a large public through argumentative reflections. Challenging the Borders of Justice in the Age of Migrations represents a fresh and timely contribution. -/- IN A TIME when national interests are structurally overvalued and borders increasingly strengthened, it’s a breath of fresh air to read a book in which migration flows are not changed into a threat. We simply cannot understand the world around us through the lens of the ‘migration crisis’-a message the authors of this book have perfectly understood. Aimed at a strong link between theories of global justice and policies of border control, this timely book combines the normative and empirical to deeply question the way our territorial boundaries are justified. Professor Ronald Tinnevelt, Radboud University Nijmegen, The Netherlands.- -/- THIS BOOK IS essential reading for those frustrated by the limitations of the dominant ways of thinking about global justice especially in relation to migration. By bringing together discussions of global justice, cosmopolitan political theory and migration, this collection of essays has the potential to transform the way in which we think and debate the critical issues of membership and movement. Together they present a critical interdisciplinary approach to international migration, human rights and global justice, challenging disciplinary borders as well as political ones.

El problema de la relación causal entre el cuerpo y la mente parece merecer, por su importancia y el tiempo a él dedicado, un capítulo aparte en la teoría del conocimiento, en la filosofía de la mente y en las ciencias cognitivas. El dualismo cuerpo-mente dificulta enormemente la explicación teórica de un nexo causal entre uno y otro, problema central en la filosofía de Descartes, más fácilmente rastreable en autores anteriores como san Agustín o Platón. En el presente trabajo analizaremos (...) el desarrollo efectuado por John Searle con el fin de superar este problema mediante una reformulación teórica de los conceptos involucrados en su descripción y conceptuación. Su tratamiento se basa en el reemplazo del concepto tradicional de causalidad por uno más complejo, mediante la introducción teórica de diferentes niveles de observación y del concepto de realización, integrante de este nuevo concepto de causalidad.

The paper critically examines Bobbio's famous disctinction between legal positivism as a method, a theory and an ideology. The author first highlights certain problems of the distinction itself and then focuses on Bobbio's self-determined position within it. Delving on Bobbio's analysis of the concepts of basic norm and rule of recognition, he demonstrates how Bobbio's later rejection of these two concepts implies acceptance of positivistic legal theory and ideology – despite the fact that he explicitly rejected them in the first (...) place. The reason for this Bobbio's slip is found in his absorbtion in the positivist legal culture which is permeated with the internal point of view on the law. The author suggests rejecting Bobbio's tripartite disctinction of legal positivism and proposes instead to view this as a set of seldom indvisible standpoints forming a specific legal culture.

Metallothioneins (MTs) are ubiquitous proteins with the capacity to bind heavy metal ions (mainly Cd, Zn or Cu), and they have been found in animals, plants, eukaryotic and prokaryotic micro‐organisms. We have carried out a comparative analysis of ciliate MTs (Tetrahymena species) to well‐known MTs from other organisms, discussing their exclusive features, such as the presence of aromatic amino acid residues and almost exclusive cysteine clusters (CCC) present in cadmium‐binding metallothioneins (CdMTs), higher heavy metal‐MT stoichiometry values, and a strictly conserved (...) modular–submodular structure. Based on this last feature and an extensive gene duplication, we propose a possible model for the evolutionary history of T. thermophila MTs. We also suggest possible functions for these MTs from consideration of their differential gene expressions and discuss the potential use of these proteins and/or their gene promoters for designing molecular or whole‐cell biosensors for a fast detection of heavy metals in diverse polluted ecosystems.

The Walmart Company is one of the favorite punching bags of market critics. They accuse this firm of underpaying employees, dealing unfairly with customers, exploiting suppliers, and bankrupting small competitors. Various political jurisdictions have banned this firm from their environs, either implicitly or explicitly. The present article offers a more nuanced position on the behemoth from Arkansas. Although it has some flaws, there is an overwhelming case to be made in its behalf as an employer, competitor, purchaser, benefactor of customers.
