The study of the theory of operators over modal pseudocomplemented De Morgan algebras was begun in papers [20] and [21]. In this paper, we introduce and study the class of modal pseudocomplemented De Morgan algebras enriched by a k-periodic automorphism -algebras). We denote by \ the automorphism where k is a positive integer. For \, the class coincides with the one studied in [20] where the automorphism works as a new unary operator which can be considered as a negation. In (...) the first place, we develop an algebraic study of the class of \-algebras; as consequence, we prove the class \-algebras is a semisimple variety and determine the generating algebras. After doing the algebraic study and using these properties, we built two families of sentential logics that we denote with \ and \ for every k. \ is a 1-assertional logic and \ is the degree-preserving logic both associated with the class of \-algebras. Working over these logics, we prove that \ is paraconsistent with respect to the de Morgan negation \, which is protoalgebraic and finitely equivalential but not algebraizable. In contrast, we prove that \ is algebraizable, sharing the same theorems with \, but not paraconsistent with respect to \. Furthermore, we show that \ and \ are paracomplete logics with respect to \ and \ and paraconsistent logics with respecto to \, for every k. (shrink)

En este trabajo se pretende abordar la historia del arte según Arthur Danto, partiremos de la distinción entre los tres distintos periodos históricos que postula, el primero de ellos lo ubicaré bajo el nombre del Periodo Prehistórico del arte, el segundo como el Periodo Histórico y finalmente el periodo Posthistórico. Cada uno será explicado de manera tal que no exista ambigüedad entre ellos, todo esto con la finalidad de esclarecer aún más la concepción que tiene Danto sobre la historia del (...) arte y poder abordar en el tercer capítulo lo que nos atañe con respecto a su tesis sobre el fin del arte. Se podrá realizar un contraste entre lo propuesto por Shinner frente Danto y resaltar la pertinencia del segundo autor partiendo del periodo Posthistórico como el que define lo acontecido en el arte contemporáneo y el fin del arte. Shinner es capaz de tejer históricamente lo que acontece con el concepto arte y sus problemáticas hasta su configuración moderna de bellas artes, después, continúa relatando sin añadir la problemática con respecto a las producciones del siglo XIX y XX, sólo nos dice que cambian las producciones, más no que el concepto lo hace con ellas. Por lo tanto, se ve la necesidad de explicar el cambio en el concepto, recurriendo a la crítica de Danto y la propuesta de un nuevo concepto capaz de incluir en su definición todo lo es una obra de arte y lo que esté en posibilidad de ser una. Lo que está en posibilidad habita en el reino prehistórico y posthistórico del arte. (shrink)

Esta ponencia presenta un avance parcial de la investigación sobre la democracia en los municipios colombianos desde la adopción de la elección popular de los alcaldes. A partir de una conceptualización básica y operacional de la democracia se determinan sus principales dimensiones y se presentan los resultados obtenidos para algunas variables significativas que se han procesado, aplicando técnicas de análisis multivariado. El objetivo final (aún en elaboración) es generar un índice de calidad democrática que permita comparar y explicar los avances (...) y retrocesos de la democracia en los muy diversos municipios colombianos.

Manuel Atria Ramírez, filósofo chileno, elaboró durante décadas una propuesta epistemológica y filosófico natural consistente, en la que la físico-matemática y la cosmovisión científica moderna fueron objeto de especial atención. En su obra, el universo sensible es sometido a un análisis riguroso, en el que se emplean y proyectan con originalidad las categorías propias de la tradición aristotélico-tomista.

The use of black box algorithms in medicine has raised scholarly concerns due to their opaqueness and lack of trustworthiness. Concerns about potential bias, accountability and responsibility, patient autonomy and compromised trust transpire with black box algorithms. These worries connect epistemic concerns with normative issues. In this paper, we outline that black box algorithms are less problematic for epistemic reasons than many scholars seem to believe. By outlining that more transparency in algorithms is not always necessary, and by explaining that (...) computational processes are indeed methodologically opaque to humans, we argue that the reliability of algorithms provides reasons for trusting the outcomes of medical artificial intelligence. To this end, we explain how computational reliabilism, which does not require transparency and supports the reliability of algorithms, justifies the belief that results of medical AI are to be trusted. We also argue that several ethical concerns remain with black box algorithms, even when the results are trustworthy. Having justified knowledge from reliable indicators is, therefore, necessary but not sufficient for normatively justifying physicians to act. This means that deliberation about the results of reliable algorithms is required to find out what is a desirable action. Thus understood, we argue that such challenges should not dismiss the use of black box algorithms altogether but should inform the way in which these algorithms are designed and implemented. When physicians are trained to acquire the necessary skills and expertise, and collaborate with medical informatics and data scientists, black box algorithms can contribute to improving medical care.

This book addresses key conceptual issues relating to the modern scientific and engineering use of computer simulations. It analyses a broad set of questions, from the nature of computer simulations to their epistemological power, including the many scientific, social and ethics implications of using computer simulations. The book is written in an easily accessible narrative, one that weaves together philosophical questions and scientific technicalities. It will thus appeal equally to all academic scientists, engineers, and researchers in industry interested in questions (...) related to the general practice of computer simulations. (shrink)

This article aims to develop a new account of scientific explanation for computer simulations. To this end, two questions are answered: what is the explanatory relation for computer simulations? And what kind of epistemic gain should be expected? For several reasons tailored to the benefits and needs of computer simulations, these questions are better answered within the unificationist model of scientific explanation. Unlike previous efforts in the literature, I submit that the explanatory relation is between the simulation model and the (...) results of the simulation. I also argue that our epistemic gain goes beyond the unificationist account, encompassing a practical dimension as well. (shrink)

En este escrito me propongo presentar una reconstrucción à la Suppes de la Teoría pictórica, representacional o figurativa del lenguaje propuesta por L. Wittgenstein en el Tractatus Logico-Philosophicus para mostrar los límites del pensamiento, o más precisamente del lenguaje como expresión sensible del pensamiento, sobre el presupuesto de la existencia no explícita por parte de su autor de un isomorfismo entre la estructura del lenguaje, como expresión sensible del pensamiento, y la del mundo; de suerte que, para que el lenguaje (...) pueda figurar algo del mundo, se requiere que entre ambas estructuras, la del lenguaje y la del mundo, se pueda establecer una función h-isomórfica no solo a nivel de sus dominios respectivos, dado que ambos poseen la misma cardinalidad, sino entre sus predicados y relatores, dada su misma aridad. Con ella pretendo dar cuenta de la compleja teoría pictórica o figurativa con el fin de diferenciar aquello que podemos decir con sentido, de aquello que únicamente podemos mostrar. (shrink)

Enhancement-line human genetic engineering has recurrently been targeted for bioethical discussion and is usually illustrated by examples alluding to a genetic technology that is far beyond our current possibilities. By discussing an ambitious project related to solid tumor cancers – multidrug resistance – the present paper places the question on a more realistic plane and draws bioethical conclusions to serve as guidelines in the field. The paper also establishes the inadequacy of the prevalent concept of genetic medicine as one of (...) substitution. (shrink)

El artículo analiza el problema de los mundos humanos a partir del concepto de mundo circundante que J. von Uexküll plantea para pensar la existencia animal. En este sentido, introduce dicho concepto biológico y sus implicancias, reconstruye las interpretaciones y críticas que se le formulan en la antropología filosófica alemana de principios del siglo XX, y defiende la idea según la cual, desde un horizonte arqueológico, habría una oposición correlativa entre el Umwelt biológico y las ideas filosóficas de mundo humano (...) previamente tematizadas.

We propose a view of identity beyond the individual in what we call interpersonal interidentities (IIIs). Within this approach, IIIs comprise collections of entangled stabilities that emerge in recurrent social interaction and manifest for those who instantiate them as relatively invariant though ever-evolving patterns of being (or more accurately, becoming) together. Herein, we consider the processes responsible for the emergence of these IIIs from the perspective of an enactive cognitive science. Our proposal hinges primarily on the development of two related (...) notions: enhabiting and coenhabiting. First, we introduce the notion of enhabiting, a set of processes at the individual level whereby structural interdependencies stabilise and thereafter undergird the habits, networks of habits, and personal identities through which we make sense of our experience. Articulating this position we lean on the notion of a tendency towards an optimal grip, though offering it a developmental framing, whereby iterative states of selective openness help realise relatively stable autonomous personal identities with their own norms of self-regulation. We then extend many of the notions found applicable here to an account of social coenhabiting, in particular, we introduce the notion of tending towards a co-optimal grip as central to the development of social habits, networks of habits, and ultimately IIIs. Such structures, we propose, also emerge as autonomous structures with their own norms of self-regulation. We wind down our account with some reflections on the implications of these structures outside of the interactions wherein they come into being and offer some thoughts about the complex animations of the individual embodied subjects that instantiate them.

In the sixteenth and seventeenth centuries, members of the Salamanca School engaged in a sustained and sophisticated discussion of the issue of just prices. This article uses their contribution as a point of departure for a consideration of justice in pricing which will be relevant to current-day circumstances. The key theses of members of this school were that fairness of exchanges should be assessed objectively, that the fair price of an article is one equal to its ‘value’, and that the (...) best indicator of that value is the price that article commonly fetches in an open market. This article tries to bring to light the attractiveness of those views in order to guide current practice by contrasting them with alternative views, showing their connection with intuitively attractive basic standards, and linking them to commonly shared intuitions.

The purpose of this paper is to define a new logic $${\mathcal {SI}}$$ called semi-intuitionistic logic such that the semi-Heyting algebras introduced in [ 4 ] by Sankappanavar are the semantics for $${\mathcal {SI}}$$ . Besides, the intuitionistic logic will be an axiomatic extension of $${\mathcal {SI}}$$.

This paper deals with the conceptual and historical-intellectual relationship that links Gilbert Simondon’s philosophy with cybernetics and information theory. For this purpose, it deploys three lines of analysis: the French reception of cybernetics and information theory, and the positioning of Simondon in that conceptual field; the transcendent meaning that Simondon assigns to them, as they express a new technological era of the twentieth century; Simondon’s criticisms of cybernetics and information theory, which tend to dismantle the nineteenth-century remains that affect them (...) from within and to think a new concept of genesis.

The variety \(\mathbb{DHMSH}\) of dually hemimorphic semi-Heyting algebras was introduced in 2011 by the second author as an expansion of semi-Heyting algebras by a dual hemimorphism. In this paper, we focus on the variety \(\mathbb{DHMSH}\) from a logical point of view. The paper presents an extensive investigation of the logic corresponding to the variety of dually hemimorphic semi-Heyting algebras and of its axiomatic extensions, along with an equally extensive universal algebraic study of their corresponding algebraic semantics. Firstly, we present a (...) Hilbert-style axiomatization of a new logic called "Dually hemimorphic semi-Heyting logic" (\(\mathcal{DHMSH}\), for short), as an expansion of semi-intuitionistic logic \(\mathcal{SI}\) (also called \(\mathcal{SH}\)) introduced by the first author by adding a weak negation (to be interpreted as a dual hemimorphism). We then prove that it is implicative in the sense of Rasiowa and that it is complete with respect to the variety \(\mathbb{DHMSH}\). It is deduced that the logic \(\mathcal{DHMSH}\) is algebraizable in the sense of Blok and Pigozzi, with the variety \(\mathbb{DHMSH}\) as its equivalent algebraic semantics and that the lattice of axiomatic extensions of \(\mathcal{DHMSH}\) is dually isomorphic to the lattice of subvarieties of \(\mathbb{DHMSH}\). A new axiomatization for Moisil's logic is also obtained. Secondly, we characterize the axiomatic extensions of \(\mathcal{DHMSH}\) in which the "Deduction Theorem" holds. Thirdly, we present several new logics, extending the logic \(\mathcal{DHMSH}\), corresponding to several important subvarieties of the variety \(\mathbb{DHMSH}\). These include logics corresponding to the varieties generated by two-element, three-element and some four-element dually quasi-De Morgan semi-Heyting algebras, as well as a new axiomatization for the 3-valued Łukasiewicz logic. Surprisingly, many of these logics turn out to be connexive logics, only a few of which are presented in this paper. Fourthly, we present axiomatizations for two infinite sequences of logics namely, De Morgan Gödel logics and dually pseudocomplemented Gödel logics. Fifthly, axiomatizations are also provided for logics corresponding to many subvarieties of regular dually quasi-De Morgan Stone semi-Heyting algebras, of regular De Morgan semi-Heyting algebras of level 1, and of JI-distributive semi-Heyting algebras of level 1. We conclude the paper with some open problems. Most of the logics considered in this paper are discriminator logics in the sense that they correspond to discriminator varieties. Some of them, just like the classical logic, are even primal in the sense that their corresponding varieties are generated by primal algebras. (shrink)

This article carries out a systematic exposition of the concept of the body in Jean-Luc Nancy, with all the risks of reduction that such an exposition entails. First it is necessary to return to Western philosophy’s founding text on living corporality, that is, Aristotle’s treatise on the soul. The oppositions that can be established between the Greek thinker’s psyche (soul) and Nancy’s dead Psyche are not so radical as may at first be thought: In both it is a question of (...) thinking the soul as the difference, the retreat or departure in which the exposition of bodies consists. The article continues with an analysis of touch and the self and concludes with an elaboration of the idea of the body within the general program of the deconstruction of Christianity. (shrink)

The main concern of this article is Weber's antagonism with respect to materialism and the distance or affinity between Marx's and Weber's standpoints. It focuses on two interconnected issues: the social and political role of religion and the emergence of modern capitalism. These two points are justified because of their strategic importance and because, with them, Weber's distance with respect to materialism apparently reaches its zenith. Through them, this text attempts to expose the main features of the controversy between Marxism (...) and Weberianism, evaluating the alternatives on the matter offered by different perspectives. Key Words: capitalism • Karl Marx • materialism • Protestant ethic • rationalism • religion • Max Weber. (shrink)

Tracing graduates has become an imperative for higher education institutions much more during the pandemic. This tracer determined the employment and employability status of the 2019 BSE graduates and identified the competencies they adequately acquired and deemed vital for work. It used descriptive design, and data were collected from the 103 graduates through a google form with open and closed-ended questions administered between November and December 2020. Results revealed that most of the graduates had been employed in teaching and teaching-related (...) jobs but mostly in contractual arrangements within the first and second six months after graduation. Many had their first jobs with meager salaries from the private sector. Communication, pedagogy, information communication technology, time management, and flexibility were the top competencies they adequately acquired and were beneficial in work. The study concluded that these graduates had acquired 21st-century skills in their respective degree programs. These results have corresponding implications for future research in confirming the most employable skills in secondary teaching. As recommended, classroom instruction might emphasize the development of these skills. Eventually, these become the competitive advantage and employability capitals of future graduates. Administering the licensure examination and the release of its results can be done within the first three months after graduation to lessen the cost of waiting. (shrink)

We would like to thank the authors of the commentaries for their critical appraisal of our feature article, Who is afraid of black box algorithms?1 Their comments, suggestions and concerns are various, and we are glad that our article contributes to the academic debate about the ethical and epistemic conditions for medical Explanatory AI. We would like to bring to attention a few issues that are common worries across reviewers. Most prominently are the merits of computational reliabilism —in particular, when (...) promoted as an alternative to transparency—and CR as necessary but not sufficient for delivering trust. We finalise our response by addressing concerns about the place and role of artificial intelligence in medical decision-making and the physician’s responsibilities. We understand the concerns and reservations that some of the reviewers express regarding the epistemic merits of CR. We believe that, in part, this is due to a practice too deeply rooted in transparency. But on …. (shrink)

Motivated by the definition of semi-Nelson algebras, a propositional calculus called semi-intuitionistic logic with strong negation is introduced and proved to be complete with respect to that class of algebras. An axiomatic extension is proved to have as algebraic semantics the class of Nelson algebras.

The growing use of genetic tests in medical practice has a strong influence on some widespread notions of health and unhealth. Two consequences of this phenomenon are: (i) important changes in the meaning of these current notions and, therefore, (ii) the arrival of a new taxonomy or rearrangement for the so-called “health-concepts”. This paper attempts to demonstrate that both facts fuel a theoretical change that might be considered a model of scientific Kuhnean change in a fundamental aspect. On the other (...) hand, this theoretical shift process offers the basis for approaching a present-day controversy, i.e. whether Western society is going through a period of geneticization or not, from a new perspective.

The traditional way of understanding life, as a self-appropriating and self-organizing process of not ceasing to exist, of taking care of one's own hunger, is challenged by today's unprecedented proliferation of discourses and techniques concerning the living being. This challenge entails questioning the fundamental concepts of metaphysical thinking--namely, time, finality, and, above all, being. Garrido argues that today we are in a position to repeat Nietzsche's assertion that there is no other representation of "being" than that of "living." But in (...) order to carry out this deconstruction of ontology, we need to find new ways of asking: What is life? In this study, Garrido establishes the basic elements of the question concerning life through readings of Aristotle, Nietzsche, Heidegger, and Derrida; through the discussion of scientific breakthroughs in thermodynamics and evolutionary and developmental biology; and through the reexamination of the notion of hunger in both its metaphysical and its political implications.

El objeto de este artículo es mostrar las similitudes que existen entre el estructuralismo metateórico sneedeano y la que considero es la propuesta teórica más desarrollada del estructuralismo francés, la teoría antropológica de Claude Lévi-Strauss, en particular, su teoría de los sistemas elementales de parentesco. Aunque entre el estructuralismo francés de Lévi-Strauss y el estructuralismo metateórico sneedeano sólo existe, como diría Wittgenstein, un “aire de familia”, sin embargo, quiero mostrar que gracias al trabajo algebraico de André Weil y, en particular, (...) a su clarificación de la noción de estructura, existe un “puente” entre la propuesta teórica de Lévi-Strauss y la metateórica del estructuralismo inaugurada por J. D. Sneed en 1971 con la publicación de su libro The logical structure of mathematical physics. (shrink)

El nacimiento de la filosofía de la ciencia profesional coincide con el desarrollo de la filosofía analítica y como ésta adopta el método del análisis lógico. Dicho análisis, en el caso de la filosofía de la ciencia, se circunscribe fundamentalmente a la elucidación lógica de la estructura interna de las teorías y de sus relaciones interteóricas inmediatas. Esta propuesta tuvo numerosas críticas, que llevaron a una nueva arquitectónica para la ciencia: la del estructuralismo metateórico. En ella se propone la reconstrucción (...) axiomática de las teorías haciéndose uso de la teoría de informal conjuntos y se introduce los aportes histórico-pragmáticos del historicismo en el contexto de una semántica informal. La introducción de la noción de holón teórico pretende ofrecer una visión más comprehensiva de las teorías científicas. Se busca pasar del análisis local de las teorías y de su entorno inmediato, donde se privilegia la relación lógica de deducibilidad, a una síntesis más global, que correspondería a la estructura global de las teorías. En este trabajo son examinadas las implicaciones que tal propuesta metateórica tiene para una filosofía sintética de la ciencia, cuando las teorías se examinan dentro de una macro-unidad como la del holón teórico. Para ello, son examinadas las nociones interteóricas de reducción aproximativa y de presuposición en algunas teorías científicas.

En este artículo analizamos la crítica que Richard Rorty hace de la apelación al “método experimental” por parte de John Dewey. Defendemos que la categórica desestimación que Rorty presenta del vínculo entre el pragmatismo de Dewey y su concepción de método hubiera sido o bien matizada, o bien radicalmente diferente, de haber considerado seriamente la importancia que la reflexión sobre la educación tenía para el filósofo de Vermont. Nuestra estrategia interpretativa se apoya en la recuperación que Henry Cowles hace recientemente (...) de la apelación al método experimental que Dewey lleva a cabo en How We Think —uno de sus textos educativos más importantes—, en donde se muestra las vinculaciones relevantes entre pragmatismo, evolucionismo y método. Este marco histórico-conceptual nos permitirá cuestionar la reconstrucción de Rorty en torno de este aspecto de la filosofía deweyana tomando en cuenta, fundamentalmente, sus propias reflexiones sobre educación.
