Neste artigo aponta-se para uma importante contribuição que o Pacto Nacional pelo Fortalecimento do Ensino Médio introduz no campo da educação, quer dizer, a possibilidade de constituição do professor-improvisador, tão defendido por Ilan Gur-Ze’ev. Como resultado desta pesquisa empírica com análise qualitativa de dados mostra-se que, sem o apoio de tais ações, a oportunidade de os indivíduos expandirem suas capacidades críticas é reduzida, comprometendo o potencial para o surgimento e/ou revelação desse professor improvisador, crítico e encorajador da crítica. Ainda: busca-se (...) destacar a importância desse tipo de ação no que concerne à valorização e à melhoria da escola pública. Palavras-chave: Formação de professores. Educação Continuada.

This article examined the personal profiles of the Heads of Government of countries in South/North America and how they communicated with their audiences on institutional measures to contain COVID-19. Analyses were carried out on data collected from Twitter from November-2019 to November-2020. This study includes: i)quantitative analysis, measuring categories and emphases in the communication of tweets, retweets, likes, and comments on matters relevant to the pandemic; ii)qualitative analysis that allowed evaluating speeches to identify political interference and the effectiveness of communication (...) at critical moments of the pandemic. It was possible to infer that each president has his singularities and understanding about Social Media’s use as a more direct communication tool with his audience. It was also found that successful communication is not directly proportional to the volume of messages on Twitter, but to socio-political aspects and institutional leadership that can make a difference in Social Media in combating COVID-19.

Trata-se de um relato de experiência sobre o projeto “Prevenção: é um prazer falar sobre isso”, com o objetivo de fomentar ações de prevenção às Infecções Sexualmente Transmissíveis (ISTs) com o público universitário. Pautadas na abordagem da educação entre pares, foram realizadas 6 oficinas com universitárias dos cursos de saúde, culminando na produção de uma intervenção denominada Barraca do Tinder. A intervenção foi realizada numa universidade pública paranaense e visava expandir o alcance do projeto, produzindo discussão sobre sexualidade, vulnerabilidade e (...) prevenção através de abordagem participativa e lúdica junto ao público universitário. Discutimos os resultados do projeto, destacando o imaginário acerca da Aids, a vulnerabilidade relacionada a populações específicas, a efetividade da metodologia da educação entre pares e do uso de cenas sexuais como dispositivos de prevenção.

Besides the general agreement about the human capability of reflection, there is a large area of disagreement and debate about the nature and value of “reflective scrutiny” and the role of “second-order states” in everyday life. This problem has been discussed in a vast and heterogeneous literature about topics such as epistemic injustice, epistemic norms, agency, understanding, meta-cognition etc. However, there is not yet any extensive and interdisciplinary work, specifically focused on the topic of the epistemic value of reflection. This (...) volume is one of the first attempts aimed at providing an innovative contribution, an exchange between philosophy, epistemology and psychology about the place and value of reflection in everyday life. -/- Our goal in the next sections is not to offer an exhaustive overview of recent work on epistemic reflection, nor to mimic all of the contributions made by the chapters in this volume. We will try to highlight some topics that have motivated a new resumption of this field and, with that, drawing on chapters from this volume where relevant. -/- Two elements defined the scope and content of this volume, on the one hand, the crucial contribution of Ernest Sosa, whose works provide original and thought-provoking contributions to contemporary epistemology in setting a new direction for old dilemmas about the nature and value of knowledge, giving a central place to reflection. On the other hand, the recent developments of cultural psychology, in the version of the “Aalborg approach”, reconsider the object and scope of psychological sciences, stressing that “[h]uman conduct is purposeful”.

A partir da instituição da Estratégia Nacional de Educação Financeira (ENEF), em 2010, no Brasil e da recomendação da Base Nacional Comum Curricular (BNCC) para a incorporação de temas como educação para o consumo, educação financeira e educação fiscal, não de forma transversal e inclusiva, o estado do Paraná incorporou o componente curricular de Educação Financeira, em 2021, para cada série do Ensino Médio de todas as escolas da rede pública de ensino estadual, incluindo escolas localizadas em áreas de Reforma (...) Agrária.Este artigo tem por objetivo apresentar e analisar as potencialidades de uma proposta de abordagem marxista para o componente curricular da Educação Financeira, em particular, com a temática do lucro, desenvolvida no curso da 1ª série do Ensino Médio, em uma escola campo localizado na área de assentamento da Reforma Agrária, considerando as orientações pedagógicas da Secretaria de Educação do Estado do Paraná do Movimento dos Trabalhadores Rurais Sem Terra (MST). Com base no materialismo histórico-dialético, esta pesquisa percorre três etapas: primeiro, a elaboração de uma proposta, considerando as diretrizes pedagógicas do MST; segundo, aplicação da proposta; e, em terceiro lugar, analisar dois resultados.A produção de dois dados da pesquisa foi realizada por meio de gravação de áudio das aulas, com posterior transcrição. As aulas serão organizadas de forma expositivo-diáloga, com questões norteadoras para o desenvolvimento de dois conceitos, de modo que os alunos apresentem suas concepções sobre os temas abordados e o professor se posicione como mediador no processo investigativo. Neste artigo, a análise está centrada apenas em uma sala de aula, na qual os objetos de conhecimento abordados são: origem do lucro e relação entre lucro e trabalho.Concluiu-se que a aplicação da proposta possibilitou a alguns distinguir aparência e essência do tema abordado, na medida em que superaram a visão inicial que apresentavam de que o lucro advém necessariamente do capital comercial, por entender que ele era trabalho aconselhado ou produtivo. Dessa forma, podemos compreender a origem do lucro através de uma perspectiva histórica e, principalmente, perceber a contradição entre lucro e trabalho. Na medida em que ultrapassaram a visão inicial que apresentavam de que o lucro resulta necessariamente do capital comercial, deixando de compreender que ele provém do trabalho produtivo. Dessa forma, podemos compreender a origem do lucro através de uma perspectiva histórica e, principalmente, perceber a contradição entre lucro e trabalho.Na medida em que ultrapassaram a visão inicial que apresentavam de que o lucro resulta necessariamente do capital comercial, deixando de compreender que ele provém do trabalho produtivo.

This study aimed to synthesize literature data on male judo combat time in international competitions between 2010 and 2019. The search was carried out from May 8th to June 11th, 2021, in electronic databases using the following keywords: AND. After the selection process, 8 articles were included in the systematic review and 7 in the meta-analysis. These studies analyzed 2,562 international male judo combats over the years 2010 to 2019. We observed that the average male judo combat time changed after (...) each rule change. There was a significant difference between combats that ended up to the regular time and those that needed overtime. There were differences between 60kg and +100kg categories and the others in 2011-2012. However, no significant difference was found between the combat time by weight division after the 2017 rule changes, although there are still differences in relation to the end of the combats. There were significant changes in the male judo combat time with each rule change, and the data from the included studies point to a trend of homogeneity in the combat time spent between the weight divisions over the years, and an increase in the occurrence of Golden Score. More studies need to be carried out to identify the new temporal behaviors of athletes. (shrink)

O presente artigo tem como pretensão oferecer um olhar outro acerca da depressão. Nossa análise sobre tal fenômeno encontra na filosofia, sobretudo, de Byung-Chul Han, uma possibilidade interessante de ir além das explicações psiquiátricas. Entretanto, são nelas que esse texto inicia sua discussão: a hipótese serotoninérgica da depressão é apresentada, mas também, problematizada, pois, muito embora a psiquiatria encontre nela ainda hoje a sua tese nuclear acerca do comportamento depressivo, é mostrado aqui que, além de ser uma teoria ausente de (...) comprovação científica, também carece de consistência para explicar o avanço da depressão ao redor do mundo. É diante da impossibilidade de pensar a depressão biologicamente que, no segundo momento deste artigo, há um esforço para analisar os modos de estruturação social contemporâneos, baseados na positivação da sociedade e na busca desenfreada por desempenho, e buscar nos mesmos, fatores desencadeantes do comportamento depressivo. A última parte do texto se concentra em apresentar um panorama filosófico centrado nas perspectivas de Han acerca da depressão. Através da exposição do mito de Eros e Psique, o artigo encerra sua análise mostrando a influência que o desaparecimento do Outro e a pressão por desempenho exerce na formação de uma sociedade de pessoas depressivas.

O presente artigo pretende analisar os regimes de visibilidade em Michel Foucault, tendo como centro da investigação sua obra Vigiar e Punir: Nascimento da prisão, de 1975. Nesta obra, Foucault se debruça sobre os processos sócio-históricos que levaram a uma mudança no regime punitivo do Ocidente entre o século XVII e início do século XIX, em que um regime de soberania deu lugar a um regime disciplinar. Pretendemos mostrar que, para além de uma mudança no regime punitivo, tal movimento produziu (...) também uma mudança na economia de visibilidade, marcando uma ruptura entre uma visibilidade espetacular centrada na integralidade e ostensividade do visível e uma nova visibilidade panóptica, cujo centro é o princípio de “ver sem ser visto”. Por fim, faremos uma análise de algumas obras fotográficas do artista norteamericano Trevor Paglen de modo a evidenciar uma contraposição artística ao panóptico contemporâneo a partir de sua inversão funcional dentro do espaço de visibilidade, onde é o próprio dispositivo panóptico que passa a ser visto sem nada ver.

Nietzsche and Education: knowledge and culture in the Modern State Abstract: This text seeks to do some reflections on the relationship between Friedrich Nietzsche's philosophy and the educational field, understanding his inquiries about modern educational institutions and the values ​​linked to this type of man. United with the process of degeneration of human instinctual power and its animality, there was the establishment of a model of knowledge, based on the metaphysical ideal and on the unconditional belief of truth. The criticism directed at the Modern State and its model of culture, which intended to establish philosophers and scholars as guides, understands that it is necessary to rescue the uses and functions of these subjects in society, seeking to overcome the dilemma that constitutes them today, as employees and keepers of the state. Passing through different phases of his thought, we sought to be one more instrument to provide the scope of Philosophy of Education with a solid link with the German philosopher, through the study of the relationship between Nietzsche and Education.

Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

Existem intertextualidades surpreendentes entre as tradições vétero e neotestamentárias. Os autores do Novo Testamento, pois, fizeram questão de ou citar literalmente algo das Sagradas Escrituras de Israel ou, de forma mais livre, fazer alusões a tais tradições. Nesse sentido, a personagem de Moisés e pormenores ligados à sua trajetória e/ou biografia, presentes nas narrativas de Êxodo a Deuteronômio, ganha maior destaque na segunda parte da Bíblia cristã. Justamente isso vale também para um discurso que, segundo a narrativa em Ex 3,1–4,17, (...) o Senhor, Deus de Israel, dirigiu a Moisés, visando à necessidade de o líder profético precisar convencer outros através de suas palavras: «Eu, pois, estarei com tua boca e te instruirei sobre o que deverás falar». Conforme os Evangelhos segundo Marcos, Mateus, Lucas e João, Jesus acolheu tal tradição e esperança religiosa ao instruir seus discípulos. A investigação dos pormenores da intertextualidade aqui indicada constitui a tarefa da pesquisa apresentada neste artigo. (shrink)

Sets are central to mathematics and its foundations, but what are they? In this book Luca Incurvati provides a detailed examination of all the major conceptions of set and discusses their virtues and shortcomings, as well as introducing the fundamentals of the alternative set theories with which these conceptions are associated. He shows that the conceptual landscape includes not only the naïve and iterative conceptions but also the limitation of size conception, the definite conception, the stratified conception and the graph (...) conception. In addition, he presents a novel, minimalist account of the iterative conception which does not require the existence of a relation of metaphysical dependence between a set and its members. His book will be of interest to researchers and advanced students in logic and the philosophy of mathematics. (shrink)

Translation of Aristotle's Posterior Analytics I into Portuguese, with a few notes, experimental glossary and introduction. The translation, which was made at 2003/4, 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.

Crispin Wright maintains that the architecture of perceptual justification is such that we can acquire justification for our perceptual beliefs only if we have antecedent justification for ruling out any sceptical alternative. Wright contends that this principle doesn’t elicit scepticism, for we are non-evidentially entitled to accept the negation of any sceptical alternative. Sebastiano Moruzzi has challenged Wright’s contention by arguing that since our non-evidential entitlements don’t remove the epistemic risk of our perceptual beliefs, they don’t actually enable us to (...) acquire justification for these beliefs. In this paper I show that Wright’s responses to Moruzzi are ineffective and that Moruzzi’s argument is validated by probabilistic reasoning. I also suggest that Wright cannot answer Moruzzi’s challenge without weakening the support available for his conception of the architecture of perceptual justification. (shrink)

In Posterior Analytics 71b9 12, we find Aristotle’s definition of scientific knowledge. The definiens is taken to have only two informative parts: scientific knowledge must be knowledge of the cause and its object must be necessary. However, there is also a contrast between the definiendum and a sophistic way of knowing, which is marked by the expression “kata sumbebekos”. Not much attention has been paid to this contrast. In this paper, I discuss Aristotle’s definition paying due attention to this contrast (...) and to the way it interacts with the two conditions presented in the definiens. I claim that the “necessity” condition ammounts to explanatory appropriateness of the cause. (shrink)

In this paper, we develop an impure somatic theory of emotion, according to which emotions are constituted by the integration of bodily perceptions with representations of external objects, events, or states of affairs. We put forward our theory by contrasting it with Prinz's pure somatic theory, according to which emotions are entirely constituted by bodily perceptions. After illustrating Prinz's theory and discussing the evidence in its favor, we show that it is beset by serious problems—i.e., it gets the neural correlates (...) of emotion wrong, it isn't able to distinguish emotions from bodily perceptions that aren't emotions, it cannot account for emotions being directed towards particular objects, and it mischaracterizes emotion phenomenology. We argue that our theory accounts for the empirical evidence considered by Prinz and solves the problems faced by his theory. In particular, we maintain that our theory gives a unified and principled account of the relation between emotions and bodily perceptions, the intentionality of emotions, and emotion phenomenology.

Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

I discuss what Aristotle means when he say that scientific demonstration must proceed from necessary principles. I argue that, for Aristotle, scientific demonstration should not be reduced to sound deduction with necessary premises. Scientific demonstration ultimately depends on the fully appropriate explanatory factor for a given explanandum. This explanatory factor is what makes the explanandum what it is. Consequently, this factor is also unique. When Aristotle says that demonstration must proceed from necessary principles, he means that each demonstration requires the (...) principle that is the necessary one for the fully appropriate explanation of its explanandum. This picture also provides a key to understand Aristotle's thesis that scientific explanation depends on essences: it is the essence of the attribute to be explained that should be stated as the fully appropriate explanatory factor.

Experiences like pains, pleasures, and emotions have affective phenomenal character: they feel pleasant or unpleasant. Imperativism proposes to explain affective phenomenal character by appeal to imperative content, a kind of intentional content that directs rather than describes. We argue that imperativism is on the right track, but has been developed in the wrong way. There are two varieties of imperativism on the market: first-order and higher-order. We show that neither is successful, and offer in their place a new theory: reflexive (...) imperativism. Our proposal is that an experience P feels pleasant in virtue of being constituted by a Command with reflexive imperative content, while an experience U feels unpleasant in virtue of being constituted by a Command with reflexive imperative content : More of P!Less of U! If you need a slogan: experiences have affective phenomenal character in virtue of commanding us Get more of me! Get less of me! (shrink)

Analyzing geometric properties of high-dimensional loss functions, such as local curvature and the existence of other optima around a certain point in loss space, can help provide a better understanding of the interplay between neural network structure, implementation attributes, and learning performance. In this work, we combine concepts from high-dimensional probability and differential geometry to study how curvature properties in lower-dimensional loss representations depend on those in the original loss space. We show that saddle points in the original space are (...) rarely correctly identified as such in expected lower-dimensional representations if random projections are used. The principal curvature in the expected lower-dimensional representation is proportional to the mean curvature in the original loss space. Hence, the mean curvature in the original loss space determines if saddle points appear, on average, as either minima, maxima, or almost flat regions. We use the connection between expected curvature in random projections and mean curvature in the original space (i.e., the normalized Hessian trace) to compute Hutchinson-type trace estimates without calculating Hessian-vector products as in the original Hutchinson method. Because random projections are not suitable to correctly identify saddle information, we propose to study projections along dominant Hessian directions that are associated with the largest and smallest principal curvatures. We connect our findings to the ongoing debate on loss landscape flatness and generalizability. Finally, for different common image classifiers and a function approximator, we show and compare random and Hessian projections of loss landscapes with up to about 7×10^6 parameters. (shrink)

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 contrast in (...) terms of explanatory claims: on the one hand, episteme covers those claims which capture explanatory connections that are universal and necessary and thereby deliver scientific understanding; on the other hand, doxa covers the explanatory attempts that fail at doing so.

I examine Aristotle’s definition of scientific knowledge in Posterior Analytics 71b 9-12 and try to understand how it relates to the sophistical way of knowing and to "kata sumbebekos knowledge". I claim that scientific knowledge of p requires knowing p by its appropriate cause, and that this appropriate cause is a universal (katholou) in the restricted sense Aristotle proposes in 73b 26-27 ff., i.e., an attribute coextensive with the subject (an extensional feature) and predicated of the subject in itself (an (...) intensional feature). Kata sumbebekos knowledge, on the other hand, can occur even when the predicate of a conclusion is coextensive with its subject and is proved by a convertible meson which is not the most appropriate from an explanatory standpoint.

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 definition of scientific knowledge, that the necessity requirement specifies (...) more exactly the causality requirement: what cannot be otherwise is the explanatory relation between the explanandum and the cause by which it is what it is.

This book uses mathematical models of language to explain why there are certain gaps in language: things that we might expect to be able to say but can't. For instance, why can we say I ran for five minutes but not *I ran to the store for five minutes? Why is five pounds of books acceptable, but *five pounds of book not acceptable? What prevents us from saying *sixty degrees of water to express the temperature of the water in a (...) swimming pool when sixty inches of water can express its depth? And why can we not say *all the ants in my kitchen are numerous? The constraints on these constructions involve concepts that are generally studied separately: aspect, plural and mass reference, measurement, and distributivity. In this book, Lucas Champollion provides a unified perspective on these domains, connects them formally within the framework of algebraic semantics and mereology, and uses this connection to transfer insights across unrelated bodies of literature and formulate a single constraint that explains each of the judgments above.

I focus on a key argument for global external world scepticism resting on the underdetermination thesis: the argument according to which we cannot know any proposition about our physical environment because sense evidence for it equally justifies some sceptical alternative (e.g. the Cartesian demon conjecture). I contend that the underdetermination argument can go through only if the controversial thesis that conceivability is per se a source of evidence for metaphysical possibility is true. I also suggest a reason to doubt that (...) conceivability is per se a source of evidence for metaphysical possibility, and thus to doubt the underdetermination argument. (shrink)

Mindreading (or folk psychology, Theory of Mind, mentalizing) is the capacity to represent and reason about others’ mental states. The Simulation Theory (ST) is one of the main approaches to mindreading. ST draws on the common-sense idea that we represent and reason about others’ mental states by putting ourselves in their shoes. More precisely, we typically arrive at representing others’ mental states by simulating their mental states in our own mind. This entry offers a detailed analysis of ST, considers theoretical (...) arguments and empirical data in favour of and against it, discusses its philosophical implications, and illustrates some alternatives to it.

A subject S's belief that Q is well-grounded if and only if it is based on a reason of S that gives S propositional justification for Q. Depending on the nature of S's reason, the process whereby S bases her belief that Q on it can vary. If S's reason is non-doxastic––like an experience that Q or a testimony that Q––S will need to form the belief that Q as a spontaneous and immediate response to that reason. If S's reason (...) is doxastic––like a belief that P––S will need to infer her belief that Q from it. The distinction between these two ways in which S's beliefs can be based on S's reasons is widely presupposed in current epistemology but––we argue in this paper––is not exhaustive. We give examples of quite ordinary situations in which a well-grounded belief of S appears to be based on S's reasons in neither of the ways described above. To accommodate these recalcitrant cases, we introduce the notion of enthymematic inference and defend the thesis that S can base a belief that Q on doxastic reasons P1, P2, …, Pn via inferring enthymematically Q from P1, P2, …, Pn.

In this article, I propose a unified account of systemic emergence, downward causation, and interlevel integrative explanations. First, I argue for a relational-transformational notion of emergence and a structural-relational account of downward causation in terms of both its transformational and conditioning effects. In my view, downward causation can avoid the problems traditionally attributed to it, provided that we are able to reconceptualize the notion of ‘whole’ and that form of causality in a purely relational way. In this regard, I distinguish (...) contextual or whole-to-part causation from downward causation, the latter defined by the existence of second-order structural relations. Finally, I argue that while emergence and downward-structural causation imply the in-principle failure of micro-determinism and therefore micro-reduction, they do not rule out the possibility of any type of explanation. On the contrary, they call for the development of interlevel integrative explanations. (shrink)

I discuss the methodological passage in the begin- ning of Ethica Eudemia I.6 (1216b26-35), which has received attention in connection with Aristotle’s notion of dialectic and his methodology in Ethics.

I will focus on how this passage coheres with the remaining parts of the same chapter, which also are advancing methodological remarks. My claim is that the meth- od of (...) Ethica Eudemia I.6 is in agreement with many features of Aristotle’s theory of explanation as presented in the Posterior Analytics: Aristotle’s main concern is a warning against misuses of explanatory arguments.

This paper examines Aristotle’s notion of priority with the specific aim of capturing the sort of priority that characterizes the primacy of substances in his metaphysics. I reject the traditional interpretation, which understands the ontological priority of substances in terms of independent existence. But there are rather two sorts of priority: the ontological priority of substances should be understood in terms of completeness, whereas the ontological priority of “substances-of-something” (the essences) is a causal-explanatory priority. Furthermore, an important piece of Aristotle’s (...) argument against Platonism is that these two sorts of priority – namely, the completeness priority and the causal-explanatory priority – should be kept distinct.

This is an introductory handbook for some of the main themes around the notion of predication in Aristotle. It does not aim at being exhaustive, but only sketches some important lines about the subject; it contains an introductory essay, besides the translation (into Portuguese) and commentary of basic texts (such as Posterior Analytics I-22, Categories 1-5, Interpretation 1-6 etc.).

This paper discusses some issues concerning the definition of moral virtue in Nicomachean Ethics 1106b 36- 1107a 2. It is reasonable to expect from a definition the complete enumeration of the relevant features of its definiendum, but the definition of moral virtue seems to fail in doing this task. One might be tempted to infer that this definition is intended by Aristotle as a mere preliminary account that should be replaced by a more precise one. The context of the argument (...) Aristotle develops in Book II of his NE give us some help. I argue that the definition of moral virtue, once considered in the light of its context, is far from being an incomplete and provisional account: it rather introduces coherently the same notion of moral virtue that Aristotle employs in other texts (as in Nicomachean Ethics VI 13). My main proposal is that the way in which "hexis" is understood in the context of previous chapters allows Aristotle to encode in it the notion of an ability to do the right things regularly. Thus, moral virtue is a "hexis prohairetike etc.", but the ability to do the right things regularly is already encoded in the occurrence of "hexis" in the definiens account of moral virtue, as if Aristotle meant "hexis [praktike] prohairetike".
