O Fisicalismo tem sido a posição filosófica monista mais aceita no mainstream do debate contemporâneo sobre a natureza do mental. Mas o que significa dizer que tudo o que existe é “físico”? O presente trabalho busca responder à pergunta: Como as teses fisicalistas contemporâneas têm definido o termo ‘físico’ em suas proposições? Para respondê-la foi realizada uma investigação teórico-filosófica baseada em revisão bibliográfica e análise lógica e conceitual. Quatro categorias gerais de definição do termo ‘físico’ foram identificadas numa revisão da (...) literatura. Existem igualmente fortes críticas às propostas de definição em toda a discussão filosófica. Não temos uma definição incontroversa do que seja uma propriedade física, tampouco consenso sobre qual deveria ser a formulação mais adequada da tese fisicalista. Assim, a questão que se coloca é: Por que estamos discutindo o valor de verdade de uma tese que nem mesmo tem conseguido ser formulada de forma adequada? (shrink)

In this paper, we argue that computer simulations can provide valuable insights into the performance of voting methods on different collective decision problems. This could improve institutional design, even when there is no general theoretical result to support the optimality of a voting method. To support our claim, we first describe a decision problem that has not received much theoretical attention in the literature. We outline different voting methods to address that collective decision problem. Under certain criteria of assessment akin (...) to extensions of the Condorcet Jury Theorem, we run simulations for the methods using MATLAB, in order to compare their performance under various conditions. We consider and respond to concerns about the use of simulations in the assessment of voting procedures for policymaking. (shrink)

Journal bearings play an important role on many rotating machines placed on industrial environments, especially in steam turbines of thermoelectric power plants. Babbitt damage (BD) and excessive clearance (C) are usual faults of steam turbine journal bearings. This paper is focused on achieving an effective identification of these faults through an intelligent recognition approach. The work was carried out through the processing of real data obtained from an industrial environment. In this work, a feature selection procedure was applied in order (...) to choose the features more suitable to identify the faults. This feature selection procedure was performed through the computation of typical testors, which allows working with both quantitative and qualitative features. The classification tasks were carried out by using Nearest Neighbors, Voting Algorithm, Naïve Associative Classifier and Assisted Classification for Imbalance Data techniques. Several performance measures were computed and used in order to assess the classification effectiveness. The achieved results (e.g., six performance measures were above 0.998) showed the convenience of applying pattern recognition techniques to the automatic identification of BD and C. (shrink)

En el Perú, el 2021 se ha caracterizado por una presencia significativa de inestabilidad política; principalmente, por la lucha mediática y pretenciosa que emprendió la candidata de ultraderecha, Keiko Fujimori, por asumir el poder y negar cualquier medio legítimo que optara el actual presidente de la República, Pedro Castillo. A ello, se le añadió el impacto negativo que dejó la pandemia del COVID-19 en los distintos ámbitos; en especial, en el económico. En ese contexto, la entrevista hecha al inversionista (...) class='Hi'>Julio César Galarreta Koicheoski busca dilucidar aquellos medios alternativos, legales y eficaces que existen para que los ciudadanos no resulten afectados. Una de sus alternativas consiste en el negocio que él está desarrollando con respecto a los préstamos que se realizan en las casas de empeño, sin que para ello se asuman riesgos mayores. Esta modalidad es muy diferente de la que emplean los bancos, las financieras, las cajas o las cooperativas de ahorro y crédito, puesto que sus clientes no requieren un historial crediticio favorable, como el de figurar en Infocorp con una calificación indeseable o el de tener préstamos impagados. Más bien, necesitan contar con un artículo que posea un valor dentro del mercado contemporáneo. La valuación, la cotización y los intereses del mismo se producirán a partir de esa lógica, con la finalidad de que exista un beneficio mutuo entre el cliente y la casa de empeño. La dinámica económica que oscila en esta conversación resulta neurálgica, merced a que brinda al lector una información que le permitirá conocer los medios a los que puede acceder para obtener un préstamo en caso de que tenga dificultades al solicitarlo en las formas tradicionales.

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)

Inauguration speech at chair number 18 of the Brasilian Academy of Philosophy.

Decoupling is a general principle that allows us to separate simple components in a complex system. In statistics, decoupling is often expressed as independence, no association, or zero covariance relations. These relations are sharp statistical hypotheses, that can be tested using the FBST - Full Bayesian Significance Test. Decoupling relations can also be introduced by some techniques of Design of Statistical Experiments, DSEs, like randomization. This article discusses the concepts of decoupling, randomization and sparsely connected statistical models in the epistemological (...) framework of cognitive constructivism. (shrink)

Abstract: In the present work we have made a critical review of the philosophical propo­ sal of Norwood R. Hanson with the aim of exposing the limits of its theoretical approach on the problem of interpretation in science. The first part of this work exposes the hansonian project, looking for evidence of his contributions to the philosophy of science and scientific thinking. In the following two sections we present a critique to his philosophical proposal. We present two exercises of philosophical (...) reflection that constitute two complementary moments of analysis. On one hand, at the level of methodological analysis, we present a discussion about how the “reversible perspective figures” that have been used for the author as arguments to explain his philosophical proposal, are insufficient to the descrip­ tion of the process of observation and interpretation. On the other hand, at the theoretical level, we question his notion of language and categories to show that his theoretical pro­ posed “vision-interpretation” has based on epistemological and analytic notions. From this perspective, it will be shown that the “hermeneutical-interpretative” approach of Hanson is incomplete, since it does not develop towards an ontology of language and observation. (shrink)

Abstract This essay seeks to realize the following question: what is the correspondence between the sign and the thing that names? In reality, what is significant is closely linked with the being, however in this case the sense will be a particular manifestation of an own subjectivity; therefore the determinant relation is limited to the capacity of representation, where the meaning is connected with the socio-cultural sense. In this regard, this work seek realize this problem from the analytical approach of (...) Ludwig Wittgenstein, who is based on the method of philosophical investigation through formal logic. In this first period of development, his speculative work, which in principle leads to the search for logical foundations for mathematics, practised it in direction to the study of the nature of the representation. Subsequently, and as necessary this test delimitation, will expose the confrontation —more not necessarily contradiction— of their approaches in the light of the own Wittgenstein who, in a second reflective period poured into his later work, is obliged to discuss the foundational in his speculative work logical-philosophical topics from a pragmatic point of view.

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.

This paper shows how an efficient and parallel algorithm for inference in Bayesian Networks (BNs) can be built and implemented combining sparse matrix factorization methods with variable elimination algorithms for BNs. This entails a complete separation between a first symbolic phase, and a second numerical phase.

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)

The authors propose a nested dissection approach to finding a fundamental cycle basis in a planar graph. The cycle basis corresponds to a fundamental null-space basis of the adjacency matrix. This problem is meant to model sparse null-space basis computations occurring in a variety of settings. An O(n3/2) bound is achieved on the nullspace basis size (i.e., the number of nonzero entries in the basis), and an O(n log n) bound on the size in the special case of grid graphs.

This study aims to deepen the philosophical aspects of the relationship between the work of Pierre Hadot and Michel Foucault, with regard to the concepts of "Spiritual Exercises" and "Self-Care". We intend to analyze how Pierre Hadot interpreted the appropriation that Michel de Foucault made of his text "spiritual exercises", when presenting the notion about the definition of "Care of the self". We elucidate the main divergences and convergences present between the philosophical reflections of these two authors, which are of (...) great relevance for the understanding of current phenomena. The methodology adopted was exploratory theoretical-bibliographic research, halfway betweena comment and an essay. Our studies point to the theme of 'the self' as the central point of the research, with “Self-Care” as the bias capable of leading us to knowledge and, in this way, taking us to the direction of existence through the rationality ofthe “Exercises” Spiritual ”. Our two authors, in their discussions about “taking care of oneself”, evoke in part the thinking of the Greeks, who are the source of the definition of this principle. Therefore, the term “epimeleia heauton” will guide us, that is, to undertake in the face of the world of life, in the practice of thorough and permanent criticism in the face of one's own conduct. In other words, by means of these spiritual exercises, thus being able to contemplate oneself rationally on a path towards "oneself" and through "oneself". Furthermore, all of this implies a constant effort on the will and desire, in order to architect authentic autonomy on a daily basis. We do not intend to exhaust the whole subject, however, the relationship to be developed will bring us closer to dominance over ourselves and make us reflect on the state of "having oneself in the hands.".

I address the objection that the concept of racism has become overly inflated. Critics of the conceptual inflation of “racism” argue that theories of institutional racism engage in untoward conceptual inflation insofar as they undermine our moral understanding of racial phenomena, hinder our ability to explain the causes of racial inequality, and even undercut struggles for racial justice. I develop an original account of institutional racism and show that it is immune to all three versions of the conceptual inflation challenge.

I defend impact-based accounts of institutional racism against the criticism that they are over-inclusive. If having a negative impact on non-whites suffices to make an institution racist, too many institutions (including institutions whose affirmative action policies inadvertently harm its intended beneficiaries) would count as racist. To address this challenge, I consider a further necessary condition for these institutions to count as racist—they must stand in a particular relation to racist ideology. I argue that, on the impact-based model, institutions are racist (...) if they have a negative racial impact AND this impact is legitimized by racist ideology. Racist ideologies limit social criticism of and collective action against institutions that have a negative racial impact, and in so doing, lend stability to systems of racial domination. (shrink)

This study presents and develops in detail (a new version of) the argumental conception of meaning. The two basic principles of the argumental conception of meaning are: i) To know (implicitly) the sense of a word is to know (implicitly) all the argumentation rules concerning that word; ii) To know the sense of a sentence is to know the syntactic structure of that sentence and to know the senses of the words occurring in it. The sense of a sentence is (...) called immediate argumental role of that sentence. According to the argumental conception of meaning a theory of meaning for a particular language yields a systematic specification of the understanding of every sentence of the language which consists in a specification of the immediate argumental role of the sentence. The immediate argumental role is a particular aspect of the use of a sentence in arguments. But it is not the whole use in arguments, nor is the whole use in arguments reducible to the immediate argumental role. That is why, by accepting the argumental conception of meaning, we can have epistemological holism without linguistic holism. The argumental conception distinguishes between the understanding and the correctness of a language. Such a distinction makes it possible to account for our understanding of paradoxical languages. Redundancy theory of truth, realistic conceptions of truth or epistemic conceptions of truth are all compatible with an argumental conception of sense. But here it is argued that an epistemic conception of truth is preferrable. Acceptance of the argumental conception of meaning and of an epistemic conception of truth leads to a rejection of the idea of analytic truth. The argumental conception is pluralistic with respect to the understandability of different logics, and neutral with respect to their correctness. (shrink)

“Identità” qui si intende nel senso già precisato da Aristotele di “identità numerica”, che si ha “quando i nomi sono parecchi, ma la cosa è una sola” e, non nel senso di “identità specifica”, che si ha invece “quando gli oggetti, pur essendo parecchi, non rivelano differenze quanto alla specie”.1 In questo articolo intendo fornire al lettore indicazioni introduttive (non certo esaustive) sul posto che la nozione di identità numerica occupa nella logica contemporanea e nell’area di riflessione filosofica del Novecento (...) più strettamente legata alla logica, la filosofia analitica.

Abstract This paper seeks to give an account of the semiotic and interpretive processes involved in the ambiguity of media representations and, in particular, of new and of different forms of construccion-difusion of information. For this reason, it is deemed the massive dissemination of information and journalistic exercis as a semiotic process in the construction of a fictitious reality. In this regard, it i sought to account for the media representation, as the contrast of the uniform character of the mass (...) expression (context of production) and the diversity of interpretations (context of reception). This review examines both component which are the concrete support that allows the individual to mean social conten non-, mid-, and intentional, thereby fostering a strong sense of social belonging.

Chi ha l'abitudine di sfogliare le riviste filosofiche sa che "metafisica" non è più una parola che scotta. I maestri dell'inizio del secolo (gli empiristi logici sono l'esempio più tipico) identificarono la metafisica con il non-senso e usarono la parola come un marchio di infamia. Non mancavano precedenti nella storia della filosofia. Ma oggi gli allievi di quei maestri preferiscono rifarsi ad un uso diverso, meno fazioso, del termine per indicare con esso un'indagine filosofica, che non solo non deve essere (...) trascurata, ma concerne i fondamenti di molte altre ricerche, ed è quindi per molti versi centrale.

El presente trabajo se circunscribe al problema de la representación y la referencialidad de la imagen, mismo que, desde la filosofía de la ciencia ha cobrado nuevos matices en el contexto de la relación entre ciencia y arte. Así pues, en esta revisión se buscará establecer tres líneas de desarrollo: en primera instancia, se planteará el problema de la representación del objeto como un campo de interés común en los ámbitos de conocimiento, tanto en la ciencia como en el arte. (...) Luego, en un segundo momento, se abordará el problema filosófico implicado en la referencialidad de la imagen, a partir de las propuestas de Max Black y Rudolph Arnheim. Finalmente, para dar respuesta a la pregunta ¿bajo qué condiciones la imagen como representación establece un objeto de referencia?, se argumentará la función epistemológica de la imagen desde el punto de vista pragmático de la semiótica trascendental. En este sentido, en este trabajo se busca establecer un punto crítico a las posturas filosóficas, tanto de Black como de Arnheim, considerando que la pregunta acerca del objeto de referencia y la imagen están en relación con las condiciones de verdad que fundamentan un sistema de lenguaje. Por ello, a partir de la semiótica pragmática y la semiótica trascendental se postularán criterios diferentes al problema de la referencialidad de la imagen, y en esta dirección, se plantearán las condiciones pragmáticas de verdad que permiten justificar el conocimiento en la imagen derivado de las prácticas epistemológicas tanto en la ciencia como en el arte.

The notion “language” seems to be stablished in a problematic and confused way: although certainly it shows an essential reality of man, on the other hand it designates various areas within the same cultural reality.

This paper argues that racism should not only be conceived as a moral concept whose main aim is to condemn severe wrongs in the domain of race. The paper advances a complementary interpretation of racism as an explanatory concept--one that plays a key role in explaining race-based social problems afflicting members of subordinate racialized groups. As an explanatory concept, the term 'racism' is used to diagnose and highlight the causes of race-related social problems. The project of diagnosing race-based social problems (...) contributes to the pragmatic anti-racist end of developing better political and policy strategies for solving these social problems. The paper defends this interpretation of racism as an explanatory concept through a critical engagement with Urquidez's moral-philosophical account of racism. (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)

La presente compilación de artículos es resultado del trabajo en colaboración realizado en el seminario institucional intitulado “Sociosemiótica y Cultura: Principios de Semiótica y Modelos de Análisis”, que durante 2016 se desarrolló en las instalaciones del Instituto de Investigaciones Sociales de la Universidad Nacional Autónoma de México (IIS-UNAM). En dicho espacio de intercambio académico se dieron cita diferentes investigadores que —desde sus particulares enfoques— contribuyeron a adoptar una visión holística acerca de los temas y problemas semióticos implicados en la investigación (...) científica. En principio, el objetivo del seminario fue la divulgación; a saber: dar a conocer la vinculación tanto teórico-empírica como teórico-metodológica de las categorías semióticas en la construcción de explicaciones científicas sobre fenómenos sociales y procesos de conocimiento en la ciencia. Para ello, el programa de presentaciones abordó diferentes ámbitos de conocimiento, tanto de las ciencias naturales: física, biología, matemáticas, lógica, como de las ciencias sociales: sociología, antropología, comunicación, al igual que estudios concretos desde las humanidades: filosofía y arte. En este sentido, acercarse a los estudios de semiótica desde diferentes disciplinas científicas (en términos generales, no sólo en ciencias sociales), obligó a reconocer el valor epistemológico de la explicación semiótica. Dicho valor consiste en aceptar que el conocimiento científico se constituye a partir de procesos de significación, donde intervienen relaciones sígnicas en el nivel lingüístico (términos, conceptos, categorías); en el nivel icónico-visual (esquemas, imágenes, diagramas), icónico-lógico (fórmulas, operaciones), entre otros; y que —en conjunto— dichas relaciones de significación dan como resultado “ensamblajes sígnicos”; es decir (a la manera de Javier Echeverría, 1985: 71 y ss.), sistemas de signos que construyen modelos explicativos, cuya validez y sentido están determinados por la coherencia/consistencia interna de dichos sistemas.

There are various proposals for a general characterization of holism1. In this paper I propose the following: a variety of holism is the view that every X of an appropriate kind, which is part of a relevant whole W, cannot be legitimately separated or taken in isolation from W. Then, I distinguish two general kinds of holism, depending on two different reasons which can debar us from taking X in isolation from W. One reason can be that separating X from (...) W always amounts to transforming X into something else. Correspondingly, a strong holism is the view that if the whole W is modified anywhere, X ceases to be X and becomes something else. Another reason why it may be illegitimate to consider X in isolation from W can be that if we separate X from W, nothing that we know entitles us to exclude that X might be transformed into something else. Correspondingly, virtual holism is the view that if the whole W is modified anywhere, we can never rule out that X ceases to be X and becomes something else. (shrink)

This paper has three main objectives: (a) Discuss the formal analogy between some important symmetry-invariance arguments used in physics, probability and statistics. Specifically, we will focus on Noether’s theorem in physics, the maximum entropy principle in probability theory, and de Finetti-type theorems in Bayesian statistics; (b) Discuss the epistemological and ontological implications of these theorems, as they are interpreted in physics and statistics. Specifically, we will focus on the positivist (in physics) or subjective (in statistics) interpretations vs. objective interpretations that (...) are suggested by symmetry and invariance arguments; (c) Introduce the cognitive constructivism epistemological framework as a solution that overcomes the realism-subjectivism dilemma and its pitfalls. The work of the physicist and philosopher Max Born will be particularly important in our discussion. (shrink)

Comments presented at the 35th International Seminar on the -- New Institutional Economics -- Empirical Methods for the Law; Syracuse, 2018.

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)

En este ensayo, evaluaremos el problema de la identidad personal en el contexto del transhumanismo. En primer lugar, en contra de la tesis de que el transhumanismo representa una amenaza a la persistencia de la identidad personal argumentaremos lo siguiente: los individuos humanos que son personas no tienen características esenciales. En segundo lugar, con la ayuda del primer episodio de la segunda temporada de la serie de ciencia ficción Black Mirror, defenderemos la tesis de que hay propiedades que realmente importan (...) en el problema de la identidad personal: las propiedades relacionales(esta tesis tiene como consecuencia que nuestros seres queridos son irremplazables, incluso por duplicados exactos). Finalmente, concluiremos que el uso de las tecnologías de mejoramiento humano no representa una amenaza a la identidad personal de un individuo en tanto que no altera sus propiedades relacionales importantes.

This article explores the metaphor of Science as provider of sharp images of our environment, using the epistemological framework of Objective Cognitive Constructivism. These sharp images are conveyed by precise scientific hypotheses that, in turn, are encoded by mathematical equations. Furthermore, this article describes how such knowledge is pro-duced by a cyclic and recursive development, perfection and reinforcement process, leading to the emergence of eigen-solutions characterized by the four essential properties of precision, stability, separability and composability. Finally, this article discusses (...) the role played by ontology and metaphysics in the scientific production process, and in which sense the resulting knowledge can be considered objective.

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.

The main goal of this article is to use the epistemological framework of a specific version of Cognitive Constructivism to address Piaget’s central problem of knowledge construction, namely, the re-equilibration of cognitive structures. The distinctive objective character of this constructivist framework is supported by formal inference methods of Bayesian statistics, and is based on Heinz von Foerster’s fundamental metaphor of objects as tokens for eigen-solutions. This epistemological perspective is illustrated using some episodes in the history of chemistry concerning the definition (...) or identification of chemical elements. Some of von Foerster’s epistemological imperatives provide general guidelines of development and argumentation. (shrink)

In this paper epistemological, ontological and sociological questions concerning the statistical significance of sharp hypotheses in scientific research are investigated within the framework provided by Cognitive Constructivism and the FBST (Full Bayesian Significance Test). The constructivist framework is contrasted with the traditional epistemological settings for orthodox Bayesian and frequentist statistics provided by Decision Theory and Falsificationism.

This article explores some open questions related to the problem of verification of theories in the context of empirical sciences by contrasting three epistemological frameworks. Each of these epistemological frameworks is based on a corresponding central metaphor, namely: (a) Neo-empiricism and the gambling metaphor; (b) Popperian falsificationism and the scientific tribunal metaphor; (c) Cognitive constructivism and the object as eigen-solution metaphor. Each of one of these epistemological frameworks has also historically co-evolved with a certain statistical theory and method for testing (...) scientific hypotheses, respectively: (a) Decision theoretic Bayesian statistics and Bayes factors; (b) Frequentist statistics and p-values; (c) Constructive Bayesian statistics and e-values. This article examines with special care the Zero Probability Paradox (ZPP), related to the verification of sharp or precise hypotheses. Finally, this article makes some remarks on Lakatos’ view of mathematics as a quasi-empirical science. (shrink)

Niccolò Machiavelli's support for what he calls governo largo, or popular government, is usually contrasted with the diffidence towards it of Francesco Guicciardini, the Florentine aristocrat. The article argues that both these authors grounded their vision on Polybius' theory of “mixed government,” though adapting it in different directions. In examining this difference, the article reaches the conclusion that it concerns far less the degree of popular participation in political decision-making and government than the value that Machiavelli and Guicciardini respectively ascribe (...) to it in comparison with that of safety-liberty. In this respect, their theories may be viewed as anticipating the tensions between democracy and the rule of law, the co-presence of which provides the essential foundation of the structure of present-day constitutional democracies.

Simultaneous hypothesis tests can fail to provide results that meet logical requirements. For example, if A and B are two statements such that A implies B, there exist tests that, based on the same data, reject B but not A. Such outcomes are generally inconvenient to statisticians (who want to communicate the results to practitioners in a simple fashion) and non-statisticians (confused by conflicting pieces of information). Based on this inconvenience, one might want to use tests that satisfy logical requirements. (...) However, Izbicki and Esteves shows that the only tests that are in accordance with three logical requirements (monotonicity, invertibility and consonance) are trivial tests based on point estimation, which generally lack statistical optimality. As a possible solution to this dilemma, this paper adapts the above logical requirements to agnostic tests, in which one can accept, reject or remain agnostic with respect to a given hypothesis. Each of the logical requirements is characterized in terms of a Bayesian decision theoretic perspective. Contrary to the results obtained for regular hypothesis tests, there exist agnostic tests that satisfy all logical requirements and also perform well statistically. In particular, agnostic tests that fulfill all logical requirements are characterized as region estimator-based tests. Examples of such tests are provided. (shrink)

Alberto Coffa used the phrase "the Copernican turn in semantics" to denote a revolutionary transformation of philosophical views about the connection between the meanings of words and the acceptability of sentences and arguments containing those words. According to the new conception resulting from the Copernican turn, here called "the Copernican view", rules of use are constitutive of the meanings of words. This view has been linked with two doctrines: (A) the instances of meaning-constitutive rules are analytically and a priori true (...) or valid; (B) to grasp a meaning is to accept its rules. The pros and cons of different versions of the Copernican view, ascribable to Wittgenstein, Carnap, Gentzen, Dummett, Prawitz, Boghossian and other authors, will be weighed. A new version will be proposed, which implies neither (A) nor (B). (shrink)

This paper introduces pragmatic hypotheses and relates this concept to the spiral of scientific evolution. Previous works determined a characterization of logically consistent statistical hypothesis tests and showed that the modal operators obtained from this test can be represented in the hexagon of oppositions. However, despite the importance of precise hypothesis in science, they cannot be accepted by logically consistent tests. Here, we show that this dilemma can be overcome by the use of pragmatic versions of precise hypotheses. These pragmatic (...) versions allow a level of imprecision in the hypothesis that is small relative to other experimental conditions. The introduction of pragmatic hypotheses allows the evolution of scientific theories based on statistical hypothesis testing to be interpreted using the narratological structure of hexagonal spirals, as defined by Pierre Gallais.
