Esa rareza que llamamos conciencia, lo más misterioso que hay en el universo, procedería de darse en ella la conjunción de dos cosas totalmente distintas: por un lado, el acto de referirse a algo y ese algo a lo cual se refiere. A esta forma de relación es a lo que tradicionalmente se ha denominado “intencionalidad” de la conciencia.

Obituario por la pérdida de un compañero.

¿Es posible pensar en acciones que orienten hacia la posibilidad de emergencia de nuevos saberes? Las derivas epistémicas de las ciencias sociales nos instan hoy a la recuperación de prácticas silenciadas y sujetos olvidados y estigmatizados, con la finalidad de aproximarnos a otros modos de construcción de conocimientos. De esta manera, intentaremos visualizar su emergencia desde sus planos geográficos, epistémicos y políticos. En este sentido, la reflexión sobre la viabilidad de las formas y patrones canónicos relacionados a la producción del (...) conocimiento en tiempos de crisis, dan lugar a la realización del presente escrito.

Heinz Von Forester characterizes the objects “known” by an autopoietic system as eigen-solutions, that is, as discrete, separable, stable and composable states of the interaction of the system with its environment. Previous articles have presented the FBST, Full Bayesian Significance Test, as a mathematical formalism specifically designed to access the support for sharp statistical hypotheses, and have shown that these hypotheses correspond, from a constructivist perspective, to systemic eigen-solutions in the practice of science. In this article several issues related to (...) the role played by language in the emergence of eigen-solutions are analyzed. The last sections also explore possible connections with the semiotic theory of Charles Sanders Peirce. (shrink)

This article considers distinct ways of understanding the world, referred to in psychology as functions of consciousness or as cognitive modes, having as the scope of interest epistemology and natural sciences. Inspired by C.G. Jung’s simile of the spectrum, we consider three basic cognitive modes associated to: (R) embodied instinct, experience, and action; (G) reality perception and learning; and (B) concept abstraction, rational thinking, and language. RGB stand for the primary colors: red, green, and blue. Accordingly, a conceptual map between (...) cognitive modes and primary and secondary colors is built based on the physics and physiology of color perception and epistemological characteristics of the aforementioned cognitive modes, leading to logical relations structured as an hexagon of opposition. Finally, this model of cognitive modes is applied to the analysis and interpretation of some important episodes in the historical development of physics and technology. (shrink)

This chapter aims to establish a philosophical discussion about the epistemological conditions of “observation”, from the cybersemiotic transdisciplinary view of knowing. For this purpose, the discussion will be divided into three parts, each one of them with the intention of outlining a conceptual critique that later allows a pertinent justification of the observation from a transcendental semiotics. This work is based on a problem: it seeks to show that a the cybersemiotic point of view, to consider on a foundationalist stance, (...) fails to overcome the epistemological contradictions involved in the contemporary critique of modern philosophy. Hence, the objective on this work is to propose as an alternative the teleological and nominalist attitude of transcendental semiotics, and also as an epistemological principle that allows overcoming problems of the foundationalist. Then, in a first moment, we will seek to establish a critique of the phenomenology of observation from the pragmatic point of view, developed by N. R. Hanson and Richard Rorty. In this direction, the contradictions involved in the definition of knowledge will be shown from the phenomenological and phenomenological positions. In general terms, the epistemological problems found in the foundations of knowledge based on observation will be exposed: specifically, the problem of the empirical basis and perception and the question of the mind as an inner space. Then, in a second moment, a characterization of the “observation” and the “observable fact” will be made from the cybersemiotic point of view. In this sense, these concepts will be described from the peircean semiosis, starting from the theoretical link proposed by Søren Brier. Hence, when considering the observation within the sphere of significance, the approaches will show a non-phenomenological characterization of knowledge and, from there, the overcoming of pragmatic critiques towards phenomenology. The closing will allow circumscribing knowledge from a communicative, semiotic and autopoietic approach. Finally, and as a contribution to the state of the discussion, the present chapter will make a defense of the cybersemiotic phenomenology of observation but considering the pragmatic conditions of knowledge from a transcendental semiotics perspective. In this sense, the transcendental concepts of truth-consensus and fin-ideal will be used to develop a relevant theoretical field that allows a transcendental justification of the communicative-intersubjective nature of knowledge postulated by cybersemiotics.

La encíclica Laudato si´ del papa Francisco plantea el vínculo irrompible que hay entre cuestiones ambientales y cuestiones sociales y humanas, a través de la categoría de la «ecología integral» y la apuesta por la «ética del cuidado». Es un excelente ejercicio de diálogo honesto y decidido del pensamiento teológico y filosófico con las aportaciones de las ciencias naturales y sociales, para preservar la supervivencia de la humanidad. Ideas similares movieron a la bioética potteriana hace más de cuarenta años, y (...) hoy, cuando la bioética no parecer atravesar su mejor momento, esta encíclica constituye un valioso impulso para reenfocar la «bioética global» y enfatizar la necesidad del diálogo tanto interdisciplinar como intercultural/interreligioso, de los cuales nuestro mundo no puede prescindir. La injusticia y la desigualdad adoptan nuevas formas en este tiempo de interdependencia global, demandando de la ética una nueva visión social, con la ampliación del campo de la moralidad que incluya a la naturaleza y de una justicia social que alcance lo global y se piense intra e intergeneracionalmente.

We review the definition of the Full Bayesian Significance Test (FBST), and summarize its main statistical and epistemological characteristics. We review also the Abstract Belief Calculus (ABC) of Darwiche and Ginsberg, and use it to analyze the FBST’s value of evidence. This analysis helps us understand the FBST properties and interpretation. The definition of value of evidence against a sharp hypothesis, in the FBST setup, was motivated by applications of Bayesian statistical reasoning to legal matters where the sharp hypotheses were (...) defendants statements, to be judged according to the Onus Probandi juridical principle.

En nuestros días las teorías cosmopolitas han experimentado una revitalización significativa al albur de la intensificación de las relaciones humanas que ha propiciado el fenómeno de la globalización. En las últimas décadas, particularmente desde la caída del Muro de Berlín, se ha registrado un florecimiento de las tesis cosmopolitas que aspiran a ofrecer un modelo teórico desde el que comprender y transformar la realidad en esta era de apertura y de creciente interdependencia que inaugura la globalización. En este trabajo realizamos (...) una aproximación histórica y conceptual al cosmopolitismo, abundando en las causas de su actual auge y, tras analizar los elementos que conforman el fenómeno de la globalización, que determina un tránsito desde la primera a la segunda modernidad, se formula una propuesta humanista e ilustrada de un _cosmopolitismo gradual_, una concepción realista cosmopolita que permita trascender la estatalidad mediante la implementación de formas de gobernanza multinivel.

This article discusses some continuous limit cases of Susan Haack’s crossword puzzle metaphor for the coherent development and foundation of science. The main objective of this discussion is to build a bridge between Haack’s foundherentism and the epistemological framework of objective cognitive constructivism, including its key metaphor of objects as tokens for eigen-solutions. The historical development of chemical affinity tables is used to illustrate our arguments.

In this article, we discuss some issues concerning magical thinking—forms of thought and association mechanisms characteristic of early stages of mental development. We also examine good reasons for having an ambivalent attitude concerning the later permanence in life of these archaic forms of association, and the coexistence of such intuitive but informal thinking with logical and rigorous reasoning. At the one hand, magical thinking seems to serve the creative mind, working as a natural vehicle for new ideas and innovative insights, (...) and giving form to heuristic arguments. At the other hand, it is inherently difficult to control, lacking effective mechanisms needed for rigorous manipulation. Our discussion is illustrated with many examples from the Hebrew Bible, and some final examples from modern science. (shrink)

This paper investigates some classical oppositional categories, like synthetic vs. analytic, posterior vs. prior, imagination vs. grammar, metaphor vs. hermeneutics, metaphysics vs. observation, innovation vs. routine, and image vs. sound, and the role they play in epistemology and philosophy of science. The epistemological framework of objective cognitive constructivism is of special interest in these investigations. Oppositional relations are formally represented using algebraic lattice structures like the cube and the hexagon of opposition, with applications in the contexts of modern color theory, (...) Kantian philosophy, Jungian psychology, and linguistics. (shrink)

This article analyzes the role of entropy in Bayesian statistics, focusing on its use as a tool for detection, recognition and validation of eigen-solutions. “Objects as eigen-solutions” is a key metaphor of the cognitive constructivism epistemological framework developed by the philosopher Heinz von Foerster. Special attention is given to some objections to the concepts of probability, statistics and randomization posed by George Spencer-Brown, a figure of great influence in the field of radical constructivism.

We formulate the problem of permuting a matrix to block angular form as the combinatorial minimization of an objective function. We motivate the use of simulated annealing (SA) as an optimization tool. We then introduce a heuristic temperature dependent penalty function in the simulated annealing cost function, to be used instead of the real objective function being minimized. Finally we show that this temperature dependent penalty function version of simulated annealing consistently outperforms the standard simulated annealing approach, producing, with smaller (...) running times, better solutions. We believe that the use of a temperature dependent penalty function may be useful in developing SA algorithms for other combinatorial problems. -/- . (shrink)

El déjà vu es problemático en el fin de siglo (XIX), no por la ensoñación poética que trae consigo, sino por la perturbación que le causa a la vida. De allí la preocupación de los “savants” por entenderlo, controlarlo y “curarlo”. El déjà vu irrumpe en la vida cotidiana del sujeto, lo perturba, lo desconcierta. De allí que Bodei lo relacione con el eterno retorno de Nietzsche. Más que un caso aislado o “patológico” ligado a individuos “pa(de)cientes” como los epilépticos, (...) o una “válvula de escape de la realidad”, el déjà vu sería para Bodei, la irrupción (la erupción) de una ilusión frente a la realidad “operante”. El déjà vu pone en crisis la supuesta identidad “absoluta” del sujeto, su dimensión del tiempo y su “confianza” en la continuidad de la personalidad. Para hablar de él es necesario, como sugiere Bodei, referirse al tema del “doble” en la literatura del siglo XIX. (Dostoievski más que Stevenson). (shrink)

Although logical consistency is desirable in scientific research, standard statistical hypothesis tests are typically logically inconsistent. To address this issue, previous work introduced agnostic hypothesis tests and proved that they can be logically consistent while retaining statistical optimality properties. This article characterizes the credal modalities in agnostic hypothesis tests and uses the hexagon of oppositions to explain the logical relations between these modalities. Geometric solids that are composed of hexagons of oppositions illustrate the conditions for these modalities to be logically (...) consistent. Prisms composed of hexagons of oppositions show how the credal modalities obtained from two agnostic tests vary according to their threshold values. Nested hexagons of oppositions summarize logical relations between the credal modalities in these tests and prove new relations. (shrink)

A Bayesian measure of evidence for precise hypotheses is presented. The intention is to give a Bayesian alternative to significance tests or, equivalently, to p-values. In fact, a set is defined in the parameter space and the posterior probability, its credibility, is evaluated. This set is the “Highest Posterior Density Region” that is “tangent” to the set that defines the null hypothesis. Our measure of evidence is the complement of the credibility of the “tangent” region.

Clearing algorithms are at the core of modern payment systems, facilitating the settling of multilateral credit messages with (near) minimum transfers of currency. Traditional clearing procedures use batch processing based on MILP - mixed-integer linear programming algorithms. The MILP approach demands intensive computational resources; moreover, it is also vulnerable to operational risks generated by possible defaults during the inter-batch period. This paper presents TORC3 - the Token-Ring Clearing Algorithm for Currency Circulation. In contrast to the MILP approach, TORC3 is a (...) real time heuristic procedure, demanding modest computational resources, and able to completely shield the clearing operation against the participating agents’ risk of default.

in Oct-14-1998 ordinance INDESP-IO4 established the federal software certification and verification requirements for gaming machines in Brazil. The authors present the rationale behind these criteria, whose basic principles can find applications in several other software authentication applications.

We study active set methods for optimization problems in Block Angular Form (BAF). We begin by reviewing some standard basis factorizations, including Saunders' orthogonal factorization and updates for the simplex method that do not impose any restriction on the pivot sequence and maintain the basis factorization structured in BAF throughout the algorithm. We then suggest orthogonal factorization and updating procedures that allow coarse grain parallelization, pivot updates local to the affected blocks, and independent block reinversion. A simple parallel environment appropriate (...) to the description and complexity analysis of test procedures is defined in Section 5. The factorization and updating procedures are presented in Sections 6 and 7. Our update procedure outperforms conventional Updating procedures even in a purely sequential environment. (shrink)

Da ficção científica para a ficção religiosa: ideias para pensar o cinema de ficção científica como o culto da religião vivida (From Science Fiction to Religious Fiction: ideas to think on Science Fiction cinema as the cult of lived religion). DOI - 10.5752/P.2175-5841.2012v10n26p552 Este artigo tem como objetivo refletir sobre a chamada religião vivida como uma forma de repensar o papel da teologia e das ciências da religião na contemporaneidade. O estudo da religião vivida será investigado na relação entre o (...) cinema de ficção científica e a religião, propondo que, nesta relação, há uma forma de religião vivida intensa e viva. Sugere-se, assim, que o cinema seja hoje uma forma de culto e ritual, cumprindo parte do papel que os mitos e ritos sagrados desempenham na vida das pessoas, ao longo dos tempos. O artigo contém quatro partes: introdução sobre a religião vivida; religião vivida no caso específico do cinema; o cinema de ficção científica como uma forma de religião; aplicação da teoria no filme “Contato” (Robert Zemeckis, USA 1997); conclusões sobre a vivência religiosa em forma de mito e rito nos filmes de ficção científica e as consequências disso para a teologia e as ciências da religião. Palavras-chave : Cinema de ficção científica. Religião. Culto e rito. Religião vivida.: This article aims at reflecting about the so-called lived religion as a way of rethinking the role of theology and religion in contemporary society. The study of the lived religion will investigate the relationship between the cinema of science fiction and religion, suggesting that, in this relation, there is particular and intensive form of lived religion. The present article suggests that cinema today is a form of cult and ritual which performs part of the role that sacred rites play in the lives of people along the time. The article contains four parts: introduction about the lived religion; lived religion in the specific case of cinema; the cinema of science fiction as a form of religion; the application of theory in the movie “Contact” (Robert Zemeckis, USA 1997); conclusions on the religious experience in the form of myth and rite in science fiction movies as well as the consequences for theology and religious studies.
