96Grit as Predictor of Entrepreneurship and Self-Employment in SpainFrontiers in Psychology 10. 2019.Extending the growing literature on the role of grit in different life domains, this research explores the relationship between grit and involvement in entrepreneurship. The research highlights the role of personal income and satisfaction with one’s current financial situation as moderators of the relationship between grit and entrepreneurial behavior. Using a large representative sample of Spanish young adults and controlling for a number of potential confounding variables, we find that grit is…Read more

57La ética del voto y el gobierno de los pocos. A propósito de Jason Brennan y John Stuart MillTélos 21 (1): 43-71. 2017.In this article Jason Brennan’s arguments about the moral duties relating to our practice of voting are examined. These arguments provide an epistocratic approach of politics and present a conception of abstention at four levels: abstention as a personal choice, as a moral responsibility, as a duty legally enforceable and as an obligation decided by lot. The contrast with John Stuart Mill’s positions helps to highlight the postdemocratic ambivalences and the latent paternalism behind Brennan’s r…Read more

46Science as public sphere?Social Epistemology 21 (1). 2007.In this paper we argue that the best way to explain the normative framework of science is to adopt a model inspired in the democratic characterization of a public sphere. This model assumes and develops some deliberative democratic principles about the inclusiveness of the concerned, the parity of the reasons and the general interest of the subjects. In contrast to both bargaining models and to power-inspired models of the scientific activities, the model of scientific public sphere proposes to …Read more

34Fragments of Arithmetic and true sentencesMathematical Logic Quarterly 51 (3): 313-328. 2005.By a theorem of R. Kaye, J. Paris and C. Dimitracopoulos, the class of the Πn+1-sentences true in the standard model is the only consistent Πn+1-theory which extends the scheme of induction for parameter free Πn+1-formulas. Motivated by this result, we present a systematic study of extensions of bounded quantifier complexity of fragments of first-order Peano Arithmetic. Here, we improve that result and show that this property describes a general phenomenon valid for parameter free schemes. As a …Read more

33A note on parameter free Π1 -induction and restricted exponentiationMathematical Logic Quarterly 57 (5): 444-455. 2011.We characterize the sets of all Π2 and all equation image theorems of IΠ−1 in terms of restricted exponentiation, and use these characterizations to prove that both sets are not deductively equivalent. We also discuss how these results generalize to n > 0. As an application, we prove that a conservation theorem of Beklemishev stating that IΠ−n + 1 is conservative over IΣ−n with respect to equation image sentences cannot be extended to Πn + 2 sentences. © 2011 WILEY-VCH Verlag GmbH & Co.

27Envelopes, indicators and conservativenessMathematical Logic Quarterly 52 (1): 51-70. 2006.A well known theorem proved by J. Paris and H. Friedman states that BΣn +1 is a Πn +2-conservative extension of IΣn . In this paper, as a continuation of our previous work on collection schemes for Δn +1-formulas , we study a general version of this theorem and characterize theories T such that T + BΣn +1 is a Πn +2-conservative extension of T . We prove that this conservativeness property is equivalent to a model-theoretic property relating Πn-envelopes and Πn-indicators for T . The analysis of…Read more

21Induction, minimization and collection for Δ n+1 (T)–formulasArchive for Mathematical Logic 43 (4): 505-541. 2004.For a theory T, we study relationships among IΔ n +1 (T), LΔ n+1 (T) and B * Δ n+1 (T). These theories are obtained restricting the schemes of induction, minimization and (a version of) collection to Δ n+1 (T) formulas. We obtain conditions on T (T is an extension of B * Δ n+1 (T) or Δ n+1 (T) is closed (in T) under bounded quantification) under which IΔ n+1 (T) and LΔ n+1 (T) are equivalent. These conditions depend on Th Πn +2 (T), the Π n+2 –consequences of T. The first condition is connected …Read more

20Predicativity through transfinite reflectionJournal of Symbolic Logic 82 (3): 787-808. 2017.Let T be a second-order arithmetical theory, Λ a well-order, λ < Λ and X ⊆ ℕ. We use $[\lambda |X]_T^{\rm{\Lambda }}\varphi$ as a formalization of “φ is provable from T and an oracle for the set X, using ω-rules of nesting depth at most λ”.For a set of formulas Γ, define predicative oracle reflection for T over Γ ) to be the schema that asserts that, if X ⊆ ℕ, Λ is a well-order and φ ∈ Γ, then$$\forall \,\lambda < {\rm{\Lambda }}\,.$$In particular, define predicative oracle consistency ) as Pred…Read more

20On the quantifier complexity of Δ n+1 (T)– inductionArchive for Mathematical Logic 43 (3): 371-398. 2004.In this paper we continue the study of the theories IΔ n+1 (T), initiated in [7]. We focus on the quantifier complexity of these fragments and theirs (non)finite axiomatization. A characterization is obtained for the class of theories such that IΔ n+1 (T) is Π n+2 –axiomatizable. In particular, IΔ n+1 (IΔ n+1 ) gives an axiomatization of Th Π n+2 (IΔ n+1 ) and is not finitely axiomatizable. This fact relates the fragment IΔ n+1 (IΔ n+1 ) to induction rule for Δ n+1 –formulas. Our arguments, invo…Read more

15Semi-honest subrecursive degrees and the collection rule in arithmeticArchive for Mathematical Logic 63 (1): 163-180. 2023.By a result of L.D. Beklemishev, the hierarchy of nested applications of the $$\Sigma _1$$ -collection rule over any $$\Pi _2$$ -axiomatizable base theory extending Elementary Arithmetic collapses to its first level. We prove that this result cannot in general be extended to base theories of arbitrary quantifier complexity. In fact, given any recursively enumerable set of true $$\Pi _2$$ -sentences, S, we construct a sound $$(\Sigma _2 \! \vee \! \Pi _2)$$ -axiomatized theory T extending S such …Read more

14In relation to the work of Ortega y Gasset, this paper aims to spotlight the importance that the reader plays in the construction of meaning of all philosophical text, beyond that marginal role it has been given in our culture. I will also try to make a critical analysis about that perspective of the didactic or pedagogical explanation towards the reader with which the literary factor of Ortega’s work has traditionally been interpreted

10Triaje Y Ética de DesastresTélos 24 (1-2): 1-16. 2022.En este artículo se analizan algunas de las implicaciones que tienen las prácticas de triaje para la ética de desastres. Se considera la centralidad técnica de la cuantificación en los modelos algorítmicos y numéricos de triaje y se incide en la prevalencia normativa de los criterios consecuencialistas, incluso cuando éstos hayan de ajustarse a sistemas de múltiples principios. Finalmente se sugiere que una concepción ética de los desastres precisa de una perspectiva compleja y integral de la ge…Read more

9Local induction and provably total computable functionsAnnals of Pure and Applied Logic 165 (9): 1429-1444. 2014.Let Iπ2 denote the fragment of Peano Arithmetic obtained by restricting the induction scheme to parameter free Π2Π2 formulas. Answering a question of R. Kaye, L. Beklemishev showed that the provably total computable functions of Iπ2 are, precisely, the primitive recursive ones. In this work we give a new proof of this fact through an analysis of certain local variants of induction principles closely related to Iπ2. In this way, we obtain a more direct answer to Kaye's question, avoiding the meta…Read more

7De la Crítica de la Razón Pura a Ser y Tiempo. La influencia del proyecto filosófico de Kant en Martin HeideggerStudia Heideggeriana 12 155-165. 2023.En esta investigación intentaremos explicitar hasta qué punto Ser y Tiempo es una suerte de tentativa por retomar, en forma correcta, el originario proyecto filosófico que Kant desplegó en su Crítica de la razón pura. Para lograr justificar nuestra conjetura nos centraremos especialmente en la obra de Heidegger Kant y el problema de la Metafísica (1929). En dicho texto nos encontraremos con una controvertida interpretación que el pensador de Meßkirch elaboró del opus magnum de Immanuel Kant. Int…Read more
