423Regressões ao Infinito em MetafísicaCompêndio Em Linha de Problemas de Filosofia Analítica. 2014.Este ensaio consiste num exame crítico da estrutura e do valor de um conjunto diverso de argumentos por regressão ao infinito que têm sido objecto de discussão recorrente na metafísica contemporânea. O seminal livro de David Armstrong Nominalism and Realism (Armstrong 1978) contém uma das mais compreensivas discussões de argumentos regressivos em metafísica, os quais variam entre argumentos que foram de facto avançados ao longo da história da disciplina (como o Argumento do Terceiro Homem, …Read more

152Mind-body dualism and the compatibility of medical methodsTheoretical Medicine and Bioethics 23 (2): 135-150. 2002.In this paper we analyse some misleading theses concerning the oldcontroversy over the relation between mind and body presented incontemporary medical literature. We undertake an epistemologicalclarification of the axiomatic structure of medical methods. Thisclarification, in turn, requires a precise philosophical explanation ofthe presupposed concepts. This analysis will establish two results: (1)that the mind-body dualism cannot be understood as a kind of biologicalvariation of the subject-obj…Read more

64The Platonism vs. Nominalism Debate from a Meta-metaphysical PerspectiveRevista Portuguesa de Filosofia 71 (2-3): 375-398. 2015.Resumo Neste artigo o autor apresenta cinco abordagens diferentes ao debate entre o platonismo e o nominalismo: a quantificacional, a reducionista, a dependência da mente / linguagem, a extensional versus intensional, a hierárquica. Cada uma apresenta suas vantagens e desvantagens que devem ser discutidas em detalhe. Palavras-chave : existência, meta-metafísica, nominalismo, platonismoIn this paper I present five different approaches to the debate between Platonism and Nominalism: the quantifier…Read more

50Handbook of Mereology (edited book)Philosophia. 2017.The present volume is the first comprehensive reference work for research on part-whole relations. The Handbook of Mereology offers a wide scope, inclusive presentation of contemporary research on part-whole relations that draws out systematic, historical, and interdisciplinary trajectories, shows the subject’s fertility, and inspires future explorations. In particular, we want to impress that mereology is much more than the study of axiomatised systems. The relationship between part and whole i…Read more

39On the Coherence of Aristotelian UniversalsSynthese 199 (3-4): 7255-7263. 2021.The current interest in the notions of ontological dependence and metaphysical grounding is usually associated with a renewal of interest in Aristotelian metaphysics. Curiously, some authors have recently argued that the Aristotelian view of universals, according to which universals depend for their existence on their exemplifiers, is incoherent from a grounding perspective. In this paper I argue that such criticism is misleading. I shall examine their arguments and clarify the supposed incohere…Read more

37Priority Nominalism: Grounding Ostrich Nominalism as a Solution to the Problem of UniversalsSpringer Verlag. 2018.This monograph details a new solution to an old problem of metaphysics. It presents an improved version of Ostrich Nominalism to solve the Problem of Universals. This innovative approach allows one to resolve the different formulations of the Problem, which represents an important meta-metaphysical achievement. In order to accomplish this ambitious task, the author appeals to the notion and logic of ontological grounding. Instead of defending Quine’s original principle of ontological commitment,…Read more

34Logic, Norms and Ontology. Recent Essays in Luso-Brazilian Analytic PhilosophyCentro de Filosofia da Universidade de Lisboa. 2012.The present special issue of Disputatio brings together some of the best work recently done in Brazil and Portugal in the tradition of analytic philosophy (broadly conceived). Over the past ten years or so we have witnessed an impressive growth of analytic philosophy in both countries, either in terms of quantity or in terms of quality of the produced philosophy. We hope that this volume capture, at least partly, the dynamics and strength of such development. The range of philosophical problems …Read more

33What Is the Problem of Universals About?Philosophica: International Journal for the History of Philosophy 30 (1): 71-89. 2022.The Problem of Universals is one of the oldest problems of metaphysics. And still, there is no agreement, neither about its nor about its. What is the most adequate formulation of the problem? And what kind of explanation does it require? My aim in this paper is to offer an overview of these two basic questions in the contemporary debate. I will present the four most important formulations (section 1), discuss their connections (section 2) and how the three most prominent are related to these fo…Read more

24Ontological Categories and the Transversality RequirementGrazer Philosophische Studien 97 (4): 619-639. 2020.Which categories of entities qualify as ontological categories? Which combinations of categories qualify as adequate systems of ontological categories? These are the two questions the author focuses on in this article. Contrary to the usual praxis in contemporary ontological literature, he addresses both questions conjointly. First, the author presents some problems of characterizing ontological categories in purely extensional terms, i.e. as widely inclusive natural classes. Second, he introduc…Read more

21Logic and IntensionalityPrincipia: An International Journal of Epistemology 14 (1): 111-24. 2010.There are different ways we use the expressions “extension” and “intension”. I specify in the first part of this paper two basic senses of this distinction, and try to show that the old metaphysical sense, by means of particular instance vs. universal, is more fundamental than the contemporary sense by means of substitutivity. In the second part, I argue that logic in general is essentially intensional, not only because logic is a rule-guided activity, but because even the extensional definition…Read more

19A crítica de Russell à concepção leibniziana das relaçõesManuscrito 29 (1): 153-183. 2006.Contra a concepção monista das relações que imputou a Leib-niz, Russell defendeu a realidade, externalidade e irredutibilidade das re-lações. Para Russell relações são entidades objetivas e não mentais; elas não são sempre essenciais para a individuação de uma entidade; e proposições relacionais não podem ser reduzidas a proposições da forma sujeito-predicado. Meu objetivo principal neste artigo é a análise dos argumentos de Russell para esta tripla tese. De modo geral, constata-se que devido à …Read more

18Something Rather Than NothingPhilosophy 97 (1): 1-22. 2022.Peter van Inwagen has given a probabilistic answer to the fundamental question ‘why is there something rather than nothing?’: There is something, because the probability of there being nothing is 0. Some philosophers have recently examined van Inwagen's argument and concluded that it does not really work. Three points are central in their criticism: the premise which states that there is only one empty possible world is false, the premise which states that all possible worlds have the same proba…Read more

12Ockham's razor and Chateaubriand's goateeManuscrito 31 (1): 139-154. 2008.In Logical Forms II Chateaubriand puts the simple question: Why should we accept Ockham’s razor? He blames the principle of reduction as an unjustified dogma of nominalism. In this paper I present a justification for it. Contrary to Russell`s conception of reduction as elimination, I propose the thesis that reduction is explanation.Em Logical Forms II, Chateaubriand levanta a questão: Por que deveríamos aceitar a navalha de Ockham? Ele critica esse princípio de redução como um dogma não justific…Read more

12Die Form der Externalität in Russells und die Ursprünge Seiner RelationstheorieGrazer Philosophische Studien 61 (1): 225-247. 2001.It is a well known fact that the beginning of analytic philosophy is grounded in Moore's and Russell's rebellion against the idealism of 19 century England. Despite of Russell's sharp criticism of his own idealistic phase, some important theses of his later realistic philosophy can only be understood in the context of a critical discussion of his own earlier idealistic philosophy. In this paper I will analyse the concept of the. This is the central logical and philosophical concepts of Russell's…Read more

11Identidade, diferença E coerência: Reflexões críticas sobre a metalógica de cirne-LimaVeritas – Revista de Filosofia da Pucrs 48 (4): 533-547. 2019.Neste artigo analiso criticamente a metalógica proposta por Cime-Lima com seus três princípios fundamentais: Identidade, Diferença e Coerência. Estes são considerados universalíssimos, pois precisam ser aplicados absolutamente tudo, inclusive a si mesmos.Disso surge a antinomia que legitima uma passagem dialética para a Filosofia da Natureza.Mostrarei: que a fundamentação do princípio de Diferença é falaciosa, e que esta metalógica gera artificialmente antinomias por meio de um uso inadequado da…Read more

7Nomes próprios entre semântica e epistemologia em RussellManuscrito 29 (2): 437-455. 2006.Este artigo pretende ser uma exposição crítica da teoria de ter-mos singulares de Russell. Nos seus textos sobre a semântica dos nomes próprios Russell defende uma forma mista de descritivismo . Infelizmente esses textos são extremamente imprecisos. Minha principal crítica será a con-fusão de Russell entre aspectos semânticos e epistemológicos.This paper is intended as a critical exposition of Russell’s theory of singular terms. In his texts about the semantics of proper names Rus-sell defends a…Read more
