14Uma Análise do Argumento a Favor do Princípio da RelatividadeIn A. Balsas & B. Nobre (eds.), The Insides of Nature: Causality and Conceptions of Nature, Axioma – Publicacoes Da Faculdade De Filosofia. pp. 125-158. 2020.According to the principle of special relativity, the laws of nature are the same for systems at rest and for systems in uniform and rectilinear motion: for the formulation of the laws of nature, the body C and the body C´, which, relative to the former, is in uniform and rectilinear motion, are equivalent. Galileo, in the Dialogue on the Two Greatest Systems of the World, developed the following argument in favor of such a principle: two bodies C and C´, which are in uniform and rectilinear mot…Read more

21Fraqueza da Vontade e LiberdadeDissertatio 1 (51): 313-337. 2020.Os casos de fraqueza da vontade (incontinência) são tidos como paradoxais. Há, pelo menos, uma tensão entre tais casos e a lei psicológica que relaciona avaliações e volições: se julgamos que fazer x é melhor do que fazer y, então queremos fazer x; porém, por vezes, julgamos que fazer x é melhor do que fazer y e, ainda assim, queremos fazer y em vez de x. Como noutras propostas, defendo que a incompatibilidade é aparente. Porém, não rejeito que haja verdadeiros casos de fraqueza da vontade. Prop…Read more

3Uma Perspectiva Axiológica do Fundamento da NormatividadePhilosophica: International Journal for the History of Philosophy 20 (39): 97-114. 2012.This paper aims to provide an adequate philosophical groundwork to normativity. More specifîcally, the author argues in favor of its axiological nature: from a philosophical point of view, normativity only becomes intelligible if values are taken into account. Therefore values arise as a necessary condition of normativity. Although not sufficient, values are the decisive condition in distinguishing norms from other relations of the same type. The thought of axiologists like Max Scheler and Nicol…Read more

27Church's Undecidability Theorem (1936): Formulation and presentation of the main ideas of its demonstrationApuntes Filosóficos 26 (50): 8-31. 2017.Church's Undecidability Theorem is one of the meta-theoretical results of the mid-third decade of the last century, which along with other limiting theorems such as those of Gödel and Tarski have generated endless reflections and analyzes, both within the framework of the formal sciences, that is, mathematics, logic and theoretical computation, as well as outside them, especially the philosophy of mathematics, philosophy of logic and philosophy of mind. We propose, as a general purpose of this a…Read more

3Apuntes para una introducción al logicismoApuntes Filosóficos 28 (55): 181-199. 2019.The following note has on purpose to introduce interested students to logicism. Our objective is not to show any new interpretation or thesis about logicism or its rebirth between the 60s and 80s of the last century. What we will do is systematically show the evolution of logicism from Frege to Russell-Whitehead, with greater emphasis on this latest development, and approach some problems that arise within that movement, for example: The logical paradoxes and the principle of intuitive comprehen…Read more

12Virtudes teóricas en tiempos de pandemia: la simplicidad contra las teorías de la conspiraciónApuntes Filosóficos 29 (57): 85-116. 2020.The turbulent times we live in, product of the COVID-19 pandemic, creating an ideal breeding ground for the proliferation of myths and conspiracy theories. These myths and theories are often popular on social media, defended by irresponsible politicians and published by the media in search of ratings or likes. But none of these meet the theoretical virtues that a good scientific theory should enjoy, in particular, none of these conspiracy theories about the disease caused by the SARS CoV-2 virus…Read more

7Un acercamiento al platonismo absoluto de CantorApuntes Filosóficos 22 (42). 2013.Hacia finales del siglo XIX se llevó a cabo una gran revolución conceptual y metodológica en la matemática. En tal revolución se empezaron a emplear conceptos, métodos y técnicas que dejaban de lado la antigua forma de hacer matemática, propia del siglo XVIII y principios del siglo XIX, y a su vez proponían un Hacer abstracto, es decir, una forma abstracta de ocuparse del ente matemático. Pero no sólo se trataba de un cambio metodológico, sino que la pregunta por los fundamentos se vuelve cada v…Read more
