675Princípio da Não-Contradição e Semântica da Predicação em AristótelesAnalytica. Revista de Filosofia 4 (2): 121-158. 1999.My object is Aristotle's discussion of principle of non-contradiction in the first stretch of Metaphysics IV.4. My main focus rests on the connections between Aristotle's discussion of the principle and some key notions of his (explicit or implied) semantics.

665Aristotle’s contrast between episteme and doxa in its context (Posterior Analytics I.33)Manuscrito 42 (4): 157-210. 2019.Aristotle contrasts episteme and doxa through the key notions of universal and necessary. These notions have played a central role in Aristotle’s characterization of scientific knowledge in the previous chapters of APo. They are not spelled out in APo I.33, but work as a sort of reminder that packs an adequate characterization of scientific knowledge and thereby gives a highly specified context for Aristotle’s contrast between episteme and doxa. I will try to show that this context introduces a …Read more

648AS RELAÇÕES ENTRE “FINS” E “MEIOS” E A RELEVÂNCIA MORAL DA PHRONESIS NA ÉTICA DE ARISTÓTELESRevista Filosófica de Coimbra 18 (35): 185-204. 2009.I discuss three kinds of relationship between ends and means (or "things that promote ends") in the Aristotelian ethical theory, in order to clarify how moral virtues and phronesis are related both in adopting ends and in determining means for virtuous actions. Phronesis seems to be mainly charged with determining means for an end given by the moral virtues, but it must involve some conception of ends too. Phronesis cannot be parasitic on moral virtue concerning the conception of ends, for …Read more

630O ser humano cultivado (pepaideumenos) em AristótelesFilosofia E Educação 9 (1): 165-196. 2017.I discuss the notion of education or educatedness (paideia) involved in the ‘educated human being’ (pepaideumenos), which Aristotle presents at the beginning of his Parts of Animals and a few other passages. The competence of educated human beings makes them able to evaluate some aspects of the explanations in a given domain without having a determinate knowledge about the specific subject-matter in that domain. I examine how such a competence is possible and how it is related to other critical …Read more

626Aristóteles e a necessidade do conhecimento científicoDiscurso 50 (2): 193-238. 2020.I discuss the exact meaning of the thesis according to which the object of scientific knowledge is necessary. The thesis is expressed by Aristotle in the Posterior Analytics, in his definition of scientific knowledge. The traditional interpretation understands this definition as depending on two parallel and independent requirements, the causality requirement and the necessity requirement. Against this interpretation, I try to show, through the examination of several passages that refer to the d…Read more

606Aristóteles e a noção de sujeito de predicação (Segundos analíticos I 22, 83a 1-14)Philósophos - Revista de Filosofia 12 (2): 107-129. 2007.This paper explores some aspects of Aristotle’s notion of subject for predications. I examine the argument Aristotle develops in Posterior Analytics I.22, 83a1-14. I argue that the notion advanced by Aristotle in that argument is different from the one found in his Categories, although they are far from being incompatible with each other. I also add some philological considerations to justify the Portuguese translation of “hypokeimenon” as “algo subjacente” (“underlying thing”) instead of “sujei…Read more

585Aristóteles, Segundos Analíticos, Livro IIInstituto de Filosofia e Ciências Humanas, Universidade de Campinas. 2004.Translation of Aristotle's Posterior Analytics II into Portuguese, with a few notes, experimental glossary and introduction. The translation, which was made at 2002 (with a new printing in 2004), was preliminary and its publication was intended to provide a didactic tool for courses as well as a provisional resource in research seminars. It needs some revision. I am currently working (slowly...) on the revision of the translation and a new revised one will surely appear at some point.

575Aristotle’s solution for Parmenides’ inconclusive argument in Physics I.3Peitho 12 (1): 41-67. 2021.I discuss the argument Aristotle ascribes to Parmenides at Physics 186a23-32. I discuss (i) the reasons why Aristotle considers it as eristic and inconclusive and (i) the solution (lusis) Aristotle proposes against it.

554EM QUE SENTIDO A VIRTUDE É MAIS EXATA QUE A TÉCNICA? NOTAS SOBRE ETHICA NICOMACHEA 1106B 14-16Dissertatio 29 43-58. 2009.This paper examines what Aristotle could have meant in Nicomachean Ethics 1106b 14-16, when he says that moral virtue is more exact than craft. Aristotle’s meaning cannot be that moral knowledge is more exact than technical knowledge. Neither the practical knowledge that an agent has about the precepts guiding his actions nor the philosophical knowledge framed in a moral theory could be described as “more exact than craft- knowledge”. My point is that Aristotle’s meaning is better understoo…Read more

545Hilemorfismo como modelo de explicação científica na filosofia da natureza em Aristóteles'Kriterion: Journal of Philosophy 41 (102): 132-164. 2000.My aim is to examine Aristotle's hylomorphism as a model for scientific explanation of living beings. I argue that the issue of matter-form relation should be connected with the opposition between the necessity of material and efficient causes and the teleology of forms. Form (as "telos") is a principle able to organize the appropriate conjunction of material and efficient causes. Formal and final causes are not a trick for filling the "gap in causation", nor are they bare heuristic tools for in…Read more

532A Noção Aristotélica de MatériaCadernos de História E Filosofia da Ciéncia 17 (1): 47-90. 2007.I discuss some of Aristotle’s scattered remarks from which one can construct his conception of matter. Aristotle seems to oscillate between two conceptions: one in which matter is the principle of becoming, another in which matter is a constituent element with no contribution for processes of becoming. Sometimes Aristotle takes matter as a thing independent in itself, and the correlated form is a feature that does not contribute to the matter’s essence, nor is a necessary condition for its exist…Read more

529Defining topics in aristotle’s topics VIPhilósophos - Revista de Filosofia 19 (2): 151-193. 2014.I argue that Topics VI does not contain any serious theory about definitions, but only a collection of advices for formulating definitions in a dialectical context, namely, definitions aiming to catch what the opponent means. Topics VI is full of inconsistencies that can be explained away by this approach: the inconsistencies reflect "acceptable opinions about definitions" that distinct groups of interlocutors accept. I also argue that the "topoi" need not be pieces of serious theory Aristotle i…Read more

507Demonstração, silogismo e causalidadeIn Lógica e Ciência em Aristóteles, Phi. pp. 61-120. 2014.This chapter argues in favour of three interrelated points. First, I argue that demonstration (as expression of scientific knowledge) is fundamentally defined as knowledge of the appropriate cause for a given explanandum: to have scientific knowledge of the explanandum is to explain it through its fully appropriate cause. Secondly, I stress that Aristotle’s notion of cause has a “triadic” structure, which fundamentally depends on the predicative formulation (or “regimentation”) of the explanandu…Read more

455Os seis requisitos das premissas da demonstração científica em AristótelesManuscrito 35 (1): 7-60. 2012.I discuss in this paper the six requirements Aristotle advances at Posterior Analytics A-2, 71b20-33, for the premisses of a scientific demonstration. I argue that the six requirements give no support for an intepretation in terms of “axiomatization”. Quite on the contrary, the six requirements can be consistently understood in a very different picture, according to which the most basic feature of a scientific demonstration is to explain a given proposition by its appropriate cause.

434Sobre a definição de naturezaKriterion: Journal of Philosophy 51 (122): 521-542. 2010.I discuss in this paper Aristotle’s definition of nature in Physics 192b 20-23. I intend to prove that this definition has to be taken as a set of three (not only two) conditions: the first condition just establishes that nature is a sort of cause; the second condition concerns the relationship between nature and the natural thing that has it as a cause; the third condition concerns the relationship between nature and the properties that natural things have from nature’s causality.

432Aristóteles e o Uso da Matemática nas Ciências da NaturezaIn M. Wrigley P. Smith (ed.), Coleção CLE (Universidade de Campinas, Brazil), Cle. pp. 207-237. 2003.I discuss the issue whether Aristotle's philosophy of science allows the use of mathematical premises or mathematical tools in general for explanaing phenomena in the natural sciences. I thereby discuss the concept of "metabasis eis allo genos" as it appears in Posterior Analytics I.7.

411Conhecimento e Opinião em Aristóteles (Segundos Analíticos I-33)In Marcelo Carvalho (ed.), Encontro Nacional Anpof: Filosofia Antiga e Medieval, Anpof. pp. 329-341. 2013.This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

387This is a translation, made by myself, of the paper to be published in Portuguese in the journal Discurso, 2020, in honour of the late professor Oswaldo Porchat. I discuss what Aristotle was trying to encode when he said that the object of scientific knowledge is necessary, or that what we know (scientifically) cannot be otherwise etc. The paper is meant as a continuation of previous papers—orientated towards a book on the Posterior Analytics—and thus does not discuss in much detail key passage…Read more

361'Não ser dito de um subjacente', 'um isto' e 'separado': o conceito de essência como subjacente e forma (Z-3)Cadernos de História E Filosofia da Ciéncia 8 (especial): 69-126. 1998.This paper is my first effort to revaluate the disagreement between two central texts for Aristotle's the conception of ousia: Categories and Metaphysics VII. Scholars have taken chapter Zeta-3 as a payment of the debt with the Categories, so that the hylomorphic analysis of the composite substance would require a revision of the subject-criterion, now improved by the addition of the “a this” and “separate” criterion. This paper, however, downgrades the importance of the Categories for understa…Read more

344"Natureza", "substância" e Metáfora em AristótelesRónai 8 (2): 246-261. 2020.This paper addresses a difficult passage from Aristotle’s Metaphysics (V. 4, 1015a11-13) in which he identifies a metaphorical use of the term “nature” (phusis) to refer to the entities which he calls “substances” (ousiai). I claim that the passage at stake deploys the very notion of metaphor on the basis of an analogy (as defined in the Poetics and in the Rhetorics), which is grounded on a weak (and, sometimes, very weak) similarity between two relations (each involving two relata). The s…Read more

330In what sense there is no science of corruptible things: an analysis of Posterior Analytics I 8Cadernos de História E Filosofia da Ciéncia 19 (1): 61-87. 2009.Aristotle claims that the object of scientific knowledge cannot be otherwise, and at Posterior Analytics I-8 he adds that there is no scientific knowledge of corruptible objects. These claims have been traditionally understood in terms of a strict requirement of eternal existence: objects of genuine scientific knowledge must be eternal in the sense that they must exist eternally. Sometimes the "eternal existence" is taken by scholars as equivalent to the timeless truth of universal propositions…Read more

328A Noção Aristotélica de OusiaDissertation, University of Campinas, Brazil (Unicamp). 2000.This PhD thesis is a careful discussion of Aristotle's Metaphysics VII (Zeta) almost line by line (or at least argument by argument). It might be interesting to know that a revised and shortened version of it was published as a book in Portuguese, "As Noções Aristotélicas de Substância e Essência", Campinas: Editora da Unicamp, 2008. Actually, I believe the original version of the PhD thesis has been superseded by the book.
