    Husserl and Hilbert on Completeness, Still.Jairo Silva - 2016 - Synthese 193 (6):1925-1947.
    In the first year of the twentieth century, in Gottingen, Husserl delivered two talks dealing with a problem that proved central in his philosophical development, that of imaginary elements in mathematics. In order to solve this problem Husserl introduced a logical notion, called “definiteness”, and variants of it, that are somehow related, he claimed, to Hilbert’s notions of completeness. Many different interpretations of what precisely Husserl meant by this notion, and its relations with Hilbert’s ones, have been proposed, but no (...)

    Husserl's Phenomenology and Weyl's Predictivism.Jairo José Da Silva - 1997 - Synthese 110 (2):277 - 296.
    In this paper I discuss the version of predicative analysis put forward by Hermann Weyl in "Das Kontinuum". I try to establish how much of the underlying motivation for Weyl's position may be due to his acceptance of a phenomenological philosophical perspective. More specifically, I analyze Weyl's philosophical ideas in connexion with the work of Husserl, in particular "Logische Untersuchungen" and "Ideen I". I believe that this interpretation of Weyl can clarify the views on mathematical existence and mathematical intuition which (...)

    On the Principle of Excluded Middle.Jairo José da Silva - 2011 - Principia: An International Journal of Epistemology 15 (2):333.
    I carry out in this paper a philosophical analysis of the principle of excluded middle (or, as it is often called in the version I favor here, principle of bivalence: any meaningful assertion is either true or false). This principle has been criticized, and sometimes rejected, on the charge that its validity depends on presuppositions that are not, some believe, universally obtainable; in particular, that any well-posed problem is solvable. My goal here is to show that, although excluded middle does (...)

    Husserl on Geometry and Spatial Representation.Jairo José Silva - 2012 - Axiomathes 22 (1):5-30.
    Husserl left many unpublished drafts explaining (or trying to) his views on spatial representation and geometry, such as, particularly, those collected in the second part of Studien zur Arithmetik und Geometrie (Hua XXI), but no completely articulate work on the subject. In this paper, I put forward an interpretation of what those views might have been. Husserl, I claim, distinguished among different conceptions of space, the space of perception (constituted from sensorial data by intentionally motivated psychic functions), that of physical (...)

    Hobbes E a Pandemia Hipotética No Leviatã: Entre a Liberdade E a Segurança.Jairo Rivaldo Silva - 2020 - Investigação Filosófica 11 (2):05.
    O aparecimento do coronavírus fez ressurgir um antigo debate no âmbito da filosofia política: o debate entre liberdade e segurança. A maioria dos países atingidos precisou adotar medidas que restringiram a liberdade dos cidadãos para conter o avanço da doença. Esse artigo tem o objetivo de apresentar a posição do filósofo inglês, Thomas Hobbes exposta no _Leviatã_, para enfrentar esse problema. O texto está dividido em três partes. Em um primeiro momento, apresento a tese de Hobbes sobre a segurança e (...)

    A Filosofia Moral E Política de Hobbes Em Duas Tradições Interpretativas Do Leviatã.Jairo Rivaldo Silva - 2020 - Investigação Filosófica 11 (1):69.
    O objetivo do presente artigo é apresentar e confrontar os pressupostos de duas tradições interpretativas _Leviatã _de Thomas Hobbes. Pretendo demonstrar como, a partir dos pressupostos e dos critérios de interpretação de cada uma delas, teremos não apenas duas abordagens diversas, mas resultados e soluções distintas para problemas políticos e morais que o próprio Hobbes buscou solucionar com essa obra. Na primeira parte do artigo, apresentarei os aspectos inovadores da nova interpretação do _Leviatã_ em contraposição às interpretações tradicionais ou ortodoxas. (...)

    Husserl's Two Notions of Completeness: Husserl and Hilbert on Completeness and Imaginary Elements in Mathematics.Jairo José Da Silva - 2000 - Synthese 125 (3):417 - 438.
    In this paper I discuss Husserl's solution of the problem of imaginary elements in mathematics as presented in the drafts for two lectures he gave in Göttingen in 1901 and other related texts of the same period, a problem that had occupied Husserl since the beginning of 1890, when he was planning a never published sequel to "Philosophie der Arithmetik" (1891). In order to solve the problem of imaginary entities Husserl introduced, independently of Hilbert, two notions of completeness (definiteness in (...)

    Husserl and Leibniz: Notes on the Mathesis Universalis.Jairo Silva & Stefania Centrone - 2017 - In Stefania Centrone (ed.), Essays on Husserl’s Logic and Philosophy of Mathematics. Springer Verlag. pp. 1-24.
    The notion of mathesis universalis appears in many of Edmund Husserl’s works, where it corresponds essentially to “a universal a priori ontology”. This paper has two purposes; one, largely exegetical, of clarifying how Husserl elaborates on Leibniz’ concept of mathesis universalis and associated notions like symbolic thinking and symbolic knowledge filtering them through the lesson of the so called “bohemian Leibniz”, Bernard Bolzano; another, more properly philosophical, of examining the role that the universal mathesis is allowed to play, and the (...)

    Structuralism and the Applicability of Mathematics.Jairo José da Silva - 2010 - Axiomathes 20 (2):229-253.
    In this paper I argue for the view that structuralism offers the best perspective for an acceptable account of the applicability of mathematics in the empirical sciences. Structuralism, as I understand it, is the view that mathematics is not the science of a particular type of objects, but of structural properties of arbitrary domains of entities, regardless of whether they are actually existing, merely presupposed or only intentionally intended.

    Husserl and Weyl.Jairo Silva - 2017 - In Stefania Centrone (ed.), Essays on Husserl’s Logic and Philosophy of Mathematics. Springer Verlag.
    In this paper, I carry out a comparative study of the philosophical views of Edmund Husserl and Hermann Weyl on issues such as mathematical existence and mathematical intuition, the validity of classical logic, the concept of logical definiteness, the nature of symbolic mathematics, the role of mathematics in empirical science, the relation of scientific theories with perception, space representation and the philosophy of geometry, and intentional constitution in general. My main goal is not simply to assess the extent of Husserl’s (...)

    In this paper I present and discuss Husserl’s concept of material a priori truth, particularly with respect to color-concepts, and show that Schlick’s criticism of Husserl’s notion is based on misunderstandings and misconceptions.
