    New Essays on Aristotle's Organon (edited book)
    Routledge. 2023.
    This collection of new essays by an international group of scholars closely examine the works of Aristotle's Organon. The Organon is the general title given to the collection of Aristotle's logical works: Categories, De Interpretatione, Prior Analytics, Posterior Analytics, Topics and Sophistical Refutations. This extremely influential collection gave Aristotle the reputation of being the founder of logic, and has helped shaped the development of logic for over two millennia. The chapters in thi…Read more

    O Que é o Monismo Anómalo?
    Philosophica: International Journal for the History of Philosophy 13 (25): 77-87. 2005.
    The aim of this paper is to present, in a clear and accessible way, Donald Davidson’s anomalous monism. I stress that what distinguishes Davidson’s monism from other identity theories of the mind is the conjunction of an identity thesis with an anti-reductionist argument, according to which there are no strict psychophysical laws.

    Equimodalidade e Hôs Epi To Poly no De Interpretatione 9
    Journal of Ancient Philosophy 15 (1): 144-172. 2021.
    In the first part of De Interpretatione 9, Aristotle introduces an argument for fatalism that he obviously does not subscribe to. Readers of the chapter wonder how Aristotle replies to that argument. In this paper I claim that the main basis of his reply is the principle of equimodality stated in 19a33 (“statements are true in the same way as the actual things are”). I defend that this principle should be interpreted in the most straightforward way, as saying that the modality with which any sta…Read more

    SI: Chalmers on Virtual Reality Introduction
    Disputatio 11 (55): 291-296. 2019.
    In June 2016, David Chalmers delivered the Petrus Hispanus Lectures at the LanCog research group, University of Lisbon, on the subject of objects, properties, and perception in virtual reality environments. The paper resulting from these lectures was subsequently published in Disputatio as “The Virtual and the Real” (vol. IX, 2017, No. 46, pp. 309–52). In it, Chalmers defends virtual realism, according to which virtual objects are bona fide digital objects with virtual counterparts of perceptibl…Read more

    After introducing Fitch’s paradox of knowability and the knower paradox, the paper critically discusses the dialetheist unified solution to both problems that Beall and Priest have proposed. It is first argued that the dialetheist approach to the knower paradox can withstand the main objections against it, these being that the approach entails an understanding of negation that is intolerably weak and that it commits dialetheists to jointly accept and reject the same thing. The lesson of the know…Read more

    Da filosofia antiga à filosofia contemporânea da acção
    In Sofia Miguens & Susana Cadilha (eds.), Acção e Ética: Conversas sobre racionalidade prática, Edições Colibri. pp. 143-162. 2011.
    In this chapter, the author presents and develops his views on the philosophy of action. One main theme is the problem of acrasia: how is it possible that a person sometimes acts freely and intentionally against his own better judgement? The author criticizes Donald Davidson’s solution to this problem for being unrealistic and exaggerating the rationality of the agent. He also presents his original way of reading Aristotle’s most famous text on this subject, in Ethica Nicomachea VII 3. The role …Read more

    Paradoxos Semânticos
    Compêndio Em Linha de Problemas de Filosofia Analítica. 2014.
    The semantic paradoxes are a family of arguments – including the liar paradox, Curry’s paradox, Grelling’s paradox of heterologicality, Richard’s and Berry’s paradoxes of definability, and others – which have two things in common: first, they make an essential use of such semantic concepts as those of truth, satisfaction, reference, definition, etc.; second, they seem to be very good arguments until we see that their conclusions are contradictory or absurd. These arguments raise serious doubts c…Read more

    Title in English: "Being a certain way without being definitely that way: a problem for supervaluationism". I argue that the supervaluationist theory of vagueness, in its most common version, is committed to a thesis – viz., the incompatibility between being-F and not-being-definitely-F – which is doubtful, unjustified and in conflict with the definition of super-truth as truth in all admissible precisifications of a vague language.

    Vagueza
    Compêndio Em Linha de Problemas de Filosofia Analítica. 2015.
    Most words in natural language are vague, that is to say, they lack sharp boundaries and, hence, they have (actual or potential) borderline cases, where the word in question neither definitely applies nor definitely fails to apply. Vagueness gives rise to paradoxes, the best known of which is the sorites (concerned with how many grains of sand are needed to make a heap). Besides offering a solution to such paradoxes, a theory of vagueness should systematically describe how the truth conditions o…Read more

    Tarskian truth and the two provinces of semantics
    Disputatio 1 (16): 26-37. 2004.
    In this paper, I argue that the cleavage between the theory of reference and the theory of meaning, which under the influence of Quine has dominated a large part of the philosophy of language of the last fifty years, is based on a misrepresentation of Tarski's achievement and on an overestimation of the scope and value of disquotation. In particular, I show that, if we accept Davidson's critique of disquotation, the same kind of reasons that Quine offered in opposition to the Carnapian theory of…Read more

    O Supervalorativismo e a Vagueza de Ordem Superior
    In Humberto Brito (ed.), Filosofia e Literatura 1, Instituto De Filosofia Da Linguagem. pp. 197-217. 2010.
    Este artigo apresenta a teoria supervalorativista da vagueza e discute a objecção, que frequentemente lhe é dirigida, segundo a qual essa teoria não consegue dar conta do fenómeno da vagueza de ordem superior.

    O que é o monismo anómalo?
    Philosophica 25 77-87. 2005.
    The aim of this paper is to present, in a clear and accessible way, Donald Davidson's anomalous monism. I stress that what distinguishes Davidson's monism from other identity theories of the mind is the conjunction of an identity thesis (viz. the thesis that every mental event is a physical event) with an anti-reductionist argument, according to which there are no strict psychophysical laws.
