    On the Consistency between the Assumption of a Special System of Reference and Special Relativity.Vasco Guerra & Rodrigo de Abreu - 2006 - Foundations of Physics 36 (12):1826-1845.
    In a previous work, we have shown that the null result of the Michelson–Morley experiment in vacuum is deeply connected with the notion of time. The same is true for the postulate of constancy of the two-way speed of light in vacuum in all frames independently of the state of motion of the emitting body. The argumentation formerly given is very general and has to be true not only within Special Relativity and its “equivalence” of all inertial frames, but as (...)

    Jesús Galíndez Suárez: docente de la Universidad de Columbia (1915-1956).David Mota Zurdo - 2022 - Arbor 198 (805):a658.
    En este artículo se analiza la labor docente de Jesús Galíndez Suárez en diferentes instituciones universitarias americanas. El objetivo es desmitificar a este político nacionalista vasco y delegado del Gobierno vasco en el exilio en Nueva York, cuya figura ha estado rodeada por la conspiración y el espionaje de la Guerra Fría debido a su misteriosa desaparición, y poner en valor una faceta habitualmente olvidada: su puesto de profesor en la Universidad de Columbia, una de las más (...)

    Voces inocentes: violence and historical reality at El Salvador.Pastor Bedolla Villaseñor - 2023 - ÍSTMICA Revista de la Facultad de Filosofía y Letras 1 (32):67-89.
    El artículo analiza cualitativamente la relación entre infancia y violencia en el contexto de la guerra civil en El Salvador (1980-1992). La reflexión es vehiculada por el examen de la película Voces inocentes (2004), como una obra socialmente producida y como una representación de la realidad histórica de índole prospectiva. El trabajo destaca el mérito del filme al visibilizar y denunciar la responsabilidad de los sustentadores primarios de la violencia ‒aún hoy impune‒ hacia la infancia salvadoreña, cuyas secuelas psicosociales (...)

    Dos cartas inéditas entre Manuel García Morente y Xavier Zubiri.Juan Carlos Infante Gómez - 2024 - Pensamiento 79 (304):1371-1390.
    Ofrecemos dos cartas inéditas entre los filósofos Manuel García Morente y Xavier Zubiri. La primera carta, escrita por el pensador giennense, viene a iluminar el itinerario de su conversión religiosa que le llevó a ordenarse sacerdote en la Iglesia católica. Dicho proceso espiritual había empezado a fraguarse el año anterior en París, durante el exilio que ambos pensadores habían compartido en la capital francesa, tras el estallido de la guerra civil española. En la segunda carta, fechada casi dos años (...)

    Computability of finite-dimensional linear subspaces and best approximation.Vasco Brattka & Ruth Dillhage - 2010 - Annals of Pure and Applied Logic 162 (3):182-193.
    We discuss computability properties of the set of elements of best approximation of some point xX by elements of GX in computable Banach spaces X. It turns out that for a general closed set G, given by its distance function, we can only obtain negative information about as a closed set. In the case that G is finite-dimensional, one can compute negative information on as a compact set. This implies that one can compute the point in whenever it is uniquely (...)

  14. The Ethics of Argumentation.Vasco Correia - 2012 - Informal Logic 32 (2):222-241.
    Normative theories of argumentation tend to assume that logical and dialectical rules suffice to ensure the rationality of argumentative discourse. Yet, in everyday debates people use arguments that seem valid in light of such rules but nonetheless biased and tendentious. This article seeks to show that the rationality of argumentation can only be fully promoted if we take into account its ethical dimension. To substantiate this claim, I review some of the empirical evidence indicating that people’s inferential reasoning is systematically (...)

    Beyond the Negative: Appropriation and Surpassing of Negative Theology in Vladimir Jankélévitch’s Philosophie Première.Vasco Baptista Marques - 2021 - Sophia 62 (2):265-273.
    In this article, we propose to question the accuracy of Jean Wahl’s definition of Vladimir Jankélévitch’s Philosophie Première (1953) as one of the “ultimate efflorescences of negative theology.” In fact, we maintain that—although conceiving the apophatic discourse as a necessary (but insufficient) stepping-stone to the absolute—the aforementioned work constitutes, if anything, an effort to overcome it by means of what we shall call a tesiphatic philosophy, i.e., one that identifies the first principle, not as the absolute negation of being, but (...)

    Completion of choice.Vasco Brattka & Guido Gherardi - 2021 - Annals of Pure and Applied Logic 172 (3):102914.
    We systematically study the completion of choice problems in the Weihrauch lattice. Choice problems play a pivotal rôle in Weihrauch complexity. For one, they can be used as landmarks that characterize important equivalences classes in the Weihrauch lattice. On the other hand, choice problems also characterize several natural classes of computable problems, such as finite mind change computable problems, non-deterministically computable problems, Las Vegas computable problems and effectively Borel measurable functions. The closure operator of completion generates the concept of total (...)

  23. Effective choice and boundedness principles in computable analysis.Vasco Brattka & Guido Gherardi - 2011 - Bulletin of Symbolic Logic 17 (1):73-117.
    In this paper we study a new approach to classify mathematical theorems according to their computational content. Basically, we are asking the question which theorems can be continuously or computably transferred into each other? For this purpose theorems are considered via their realizers which are operations with certain input and output data. The technical tool to express continuous or computable relations between such operations is Weihrauch reducibility and the partially ordered degree structure induced by it. We have identified certain choice (...)

    Weihrauch degrees, omniscience principles and weak computability.Vasco Brattka & Guido Gherardi - 2011 - Journal of Symbolic Logic 76 (1):143 - 176.
    In this paper we study a reducibility that has been introduced by Klaus Weihrauch or, more precisely, a natural extension for multi-valued functions on represented spaces. We call the corresponding equivalence classes Weihrauch degrees and we show that the corresponding partial order induces a lower semi-lattice. It turns out that parallelization is a closure operator for this semi-lattice and that the parallelized Weihrauch degrees even form a lattice into which the Medvedev lattice and the Turing degrees can be embedded. The (...)

    Effective Borel measurability and reducibility of functions.Vasco Brattka - 2005 - Mathematical Logic Quarterly 51 (1):19-44.
    The investigation of computational properties of discontinuous functions is an important concern in computable analysis. One method to deal with this subject is to consider effective variants of Borel measurable functions. We introduce such a notion of Borel computability for single-valued as well as for multi-valued functions by a direct effectivization of the classical definition. On Baire space the finite levels of the resulting hierarchy of functions can be characterized using a notion of reducibility for functions and corresponding complete functions. (...)

    The Discontinuity Problem.Vasco Brattka - 2023 - Journal of Symbolic Logic 88 (3):1191-1212.
    Matthias Schröder has asked the question whether there is a weakest discontinuous problem in the topological version of the Weihrauch lattice. Such a problem can be considered as the weakest unsolvable problem. We introduce the discontinuity problem, and we show that it is reducible exactly to the effectively discontinuous problems, defined in a suitable way. However, in which sense this answers Schröder’s question sensitively depends on the axiomatic framework that is chosen, and it is a positive answer if we work (...)

    A computable version of Banach’s Inverse Mapping Theorem.Vasco Brattka - 2009 - Annals of Pure and Applied Logic 157 (2-3):85-96.
    Given a program of a linear bounded and bijective operator T, does there exist a program for the inverse operator T−1? And if this is the case, does there exist a general algorithm to transfer a program of T into a program of T−1? This is the inversion problem for computable linear operators on Banach spaces in its non-uniform and uniform formulation, respectively. We study this problem from the point of view of computable analysis which is the Turing machine based (...)

    Computability of compact operators on computable Banach spaces with bases.Vasco Brattka & Ruth Dillhage - 2007 - Mathematical Logic Quarterly 53 (4‐5):345-364.
    We develop some parts of the theory of compact operators from the point of view of computable analysis. While computable compact operators on Hilbert spaces are easy to understand, it turns out that these operators on Banach spaces are harder to handle. Classically, the theory of compact operators on Banach spaces is developed with the help of the non-constructive tool of sequential compactness. We demonstrate that a substantial amount of this theory can be developed computably on Banach spaces with computable (...)

    Enfranchising Minors and the Mentally Impaired.Claudio López-Guerra - 2012 - Social Theory and Practice 38 (1):115-138.
    This article advances three claims. The first is that the standard instrumentalist case for minimal age and sanity requirements for voting is weak and inconclusive in such a way that the evaluation of such requirements should be made exclusively on the basis of procedural fairness considerations. The second claim is that fairness requires the inclusion of all and only those persons who have the franchise capacity: the minimum necessary cognitive and moral powers to experience the benefits of enfranchisement. The third (...)

    Democracy and Disenfranchisement: The Morality of Electoral Exclusions.Claudio López-Guerra - 2014 - Oxford University Press.
    The denial of voting rights to certain types of persons continues to be a moral problem of practical significance. The disenfranchisement of persons with mental impairments, minors, noncitizen residents, nonresident citizens, and criminal offenders is a matter of controversy. This book makes a contribution to this largely neglected yet key topic.

    (1 other version)Contextual Debiasing and Critical Thinking: Reasons for Optimism.Vasco Correia - forthcoming - Topoi 35 (1):1-9.
    In this article I argue that most biases in argumentation and decision-making can and should be counteracted. Although biases can prove beneficial in certain contexts, I contend that they are generally maladaptive and need correction. Yet critical thinking alone seems insufficient to mitigate biases in everyday contexts. I develop a contextualist approach, according to which cognitive debiasing strategies need to be supplemented by extra-psychic devices that rely on social and environmental constraints in order to promote rational reasoning. Finally, I examine (...)

    On the Uniform Computational Content of the Baire Category Theorem.Vasco Brattka, Matthew Hendtlass & Alexander P. Kreuzer - 2018 - Notre Dame Journal of Formal Logic 59 (4):605-636.
    We study the uniform computational content of different versions of the Baire category theorem in the Weihrauch lattice. The Baire category theorem can be seen as a pigeonhole principle that states that a complete metric space cannot be decomposed into countably many nowhere dense pieces. The Baire category theorem is an illuminating example of a theorem that can be used to demonstrate that one classical theorem can have several different computational interpretations. For one, we distinguish two different logical versions of (...)

    We prove that the Weihrauch lattice can be transformed into a Brouwer algebra by the consecutive application of two closure operators in the appropriate order: first completion and then parallelization. The closure operator of completion is a new closure operator that we introduce. It transforms any problem into a total problem on the completion of the respective types, where we allow any value outside of the original domain of the problem. This closure operator is of interest by itself, as it (...)

    Borel complexity and computability of the Hahn–Banach Theorem.Vasco Brattka - 2008 - Archive for Mathematical Logic 46 (7-8):547-564.
    The classical Hahn–Banach Theorem states that any linear bounded functional defined on a linear subspace of a normed space admits a norm-preserving linear bounded extension to the whole space. The constructive and computational content of this theorem has been studied by Bishop, Bridges, Metakides, Nerode, Shore, Kalantari Downey, Ishihara and others and it is known that the theorem does not admit a general computable version. We prove a new computable version of this theorem without unrolling the classical proof of the (...)
