13Is and Ought: Where Does the Problem Lie?In Paolo Di Lucia & Edoardo Fittipaldi (eds.), Revisiting Searle on Deriving “Ought” From “Is”, Springer Verlag. pp. 33-57. 2021.The chapter has two parts. In the first part, I introduce a more fine-grained analysis of evaluative sentences. I distinguish between evaluations proper and directions for action with several degrees of constraint: commands, pieces of advice, suggestions, and so on. I call the latter “ductive-statements.” Thus, I affirm that the realm of morals has two branches: one relative to evaluations, which are is-sentences ranging from the several degrees between good and bad to the indifferent ; the othe…Read more

18A Proposta (I)Modesta de BerkeleyPhilosophica: International Journal for the History of Philosophy 19 (38): 59-73. 2011.Berkeley’s general tenet about immaterialism is presented and discussed. I examined apart the several theses that concur to the immaterialist theory. After that, the general argument is presented and discussed. In particular, I stress Berkeley’s assumption that a world without matter and a world with matter would be indistinguishable from the point of view of the content of perceptions, natural science. I stress that this assumption depends on a relative account of circular motion, generating th…Read more

10O Homem Verdadeiro e a Máquina de TerraPhilosophica: International Journal for the History of Philosophy 6 (12): 145-171. 1998.En partant des derniers paragraphes de la cinquième parti du Discours de la Méthode, on a reconstitué la formulation cartésienne de la perception d’un autre moi. Les critères de l’usage du langage et de la plasticité du comportement ont été analysés à la lumière de l’idée d’une machine universelle et du test de Turing. On conclut de la faiblesse de l’argument cartésien sur l’irréductibilité de la pensée à un dispositif machinal. En tant qu’issue de la difficulté, on propose une révision de la fa…Read more

13Que Verdade no Erro de Descartes?Philosophica: International Journal for the History of Philosophy 4 (7): 171-178. 1996.Dans un contrepoint polémique au livre de A. Damásio, L'Erreur de Descartes, nous soutenons: que la thèse de l a «séparation» de l’âme et du corps permet, dans les écrits physiologiques de Descartes tels que le Traité de l'Homme, une réduction des fonctions végétative et sensitive aux processus mécaniques et naturels du corps humain; que l'in troduction d'une âme dans le corps se justifie, chez Descartes, par l'impossibilité de rendre raison de la rationalité du comportement humain et de la cons…Read more

18A Ideia de uma Filosofia Primeira na Fenomenologia de Edmund HusserlPhilosophica: International Journal for the History of Philosophy 4 (7): 3-37. 1996.In dieser Arbeit wird die Selbstdarstellung der Phänomenologie als Wissenschaft der Weltkonstituierende transzendentale n Subjektivität, nach einer Erklärung über das, was wir die «Grundfrage» der Phänomenologie nennen, betrachtet. Diese Grundfrage ist die thematisierung des unerklärt Voraussetzung aller philosophischer und wissenschaftlicher Erkenntnis: die Vorgegebenheit einer Welt als Horizont für alle aktuelle oder mögliche Forschung. Die phänomenologischen Begriffe von «Reduktion», «Intenti…Read more

9Kant e Beck Face ao Problema da "Coisa-Em-Si"Philosophica: International Journal for the History of Philosophy 1 (2): 53-81. 1993.In dieser Arbeit werden die Thesen S. J. Becks über den kantischen Begriff von Ding-an-sich geprüft. Es sollen weder die zwei Doktrinen verglichen werden, noch die Punkte, in denen sie übereinstimmen, noch die Punkte, in denen sie sich voneinander entfernen. Basis-Voraussetzung ist mehr die Idee, dass es eine kantische Lehre des Ding-an-sich nicht gibt, sondern, dass es vielfältige divergente Tendenzen gibt in der Art, wie Kant das Problem bearbeitet. Die Auffassung Becks wird als ein Dialog mit…Read more

24In this paper I address some philosophical questions regarding the impact quantum mechanics has in the classical conceptions about reality and knowledge. I stress that onto-gnosiological realism still is an option to the issues regarding the relationship between knowledge and reality. Rejecting some radical aspects of Copenhagen interpretation of quantum formalism, I emphasize the advantages of de Broglie’s realistic and causal model. To finish with, I discuss the limits of the Cartesian concept…Read more

24Consciência intencional e autoconsciência. As teses de Brentano perante as teorias de ordem superiorInvestigaciones Fenomenológicas 7 391. 2021.En este artículo, examino algunas características importantes de las teorías de conciencia y autoconciencia de Brentano y Rosenthal. En particular, analizo la distinción entre estados mentales y estados conscientes, y la cuestión relacionada con de determinar si todos los estados mentales pueden convertirse en estados conscientes. Interpreto la teoría de Brentano como una teoría de la mente de un nivel que está de acuerdo con la fusión cartesiana entre los estados mentales y la conciencia. Argum…Read more

13Self-consciousness and Intentionality. A Reappraisal of Brentano’s and Rosenthal’s ThesesDiscipline filosofiche. 25 (2): 149-165. 2015.In this paper, I examine some important features of Brentano’s and Rosenthal’s theories of consciousness and self-consciousness. In particular, I discuss the distinction between mental states and conscious states, and the related question of determining whether all mental states can become conscious states. I interpret Brentano’s theory as a one-level theory of mind which is in keeping with the Cartesian conflation between mental states and consciousness. I argue that the problems arising from B…Read more

28Fritz London and the measurement problem: a phenomenological approachContinental Philosophy Review 54 (4): 453-481. 2020.In this paper, I discuss the possible relations between Fritz London’s account of the status of the observer in quantum physics and transcendental phenomenology. Firstly, I discuss Steven French’s interpretation of London’s thesis as a phenomenological account of the status of the observer, along with the objections Otávio Bueno has brought forward. Secondly, refusing in part both French’s and Bueno’s theses for several reasons, I propose another way of reading London’s thesis in the framework o…Read more

37É O idealismo de Husserl compatível com um realismo metafísico?Philósophos - Revista de Filosofia 21 (1): 139-169. 2016.In this paper, I argue that the transcendental idealism of Husserl’s phenomenology is compatible with a metaphysical realism. I not only develop an argument regarding the consistency between both philosophical stances, but I argue that this was Husserl’s own thesis. As a consequence, I support my interpretation on a hermeneutic of some of the most important texts by Husserl himself, where he deals directly with the issue.

The concept of a transcendental logic: Série 2Kant E-Prints 5 132-144. 2010.In this paper I try to show how transcendental logic can be interpreted in light of the distinction between apophantics and formal ontology. Despite the non-Kantian origin of these concepts, my contention is that they can reveal the scope of Kant’s argument regarding the distinction between formal and transcendental logic and the thesis that transcendental logic has a pure a priori content. While common approaches interpret this a priori content of transcendental logic as the content pure forms …Read more
