Investigating the writings of the Francesco Filelfo (1398-1481), twelve scholars are shedding new light on Filelfo’s intellectual endeavors and literary journey. This collection offers new inroads into Filelfo’s vast oeuvre, and through it to the world of Quattrocento humanism.

Editors of Cicero'sPro Archiahave assumed that Petrarch's lost transcription of the equally lost Liège manuscript that he discovered in 1333 survives in an almost unaltered version in a single Florentine manuscript, while the remaining 265Italireflect another stage of the text, when conjectural corrections by its learned discoverer were introduced into the text. This article proposes a reassessment of that dichotomy, based on a first comprehensive study of the whole transmission.

This article first presents a codicological and paleographical analysis of the Bibliotheca Medicea Laurenziana's manuscript Plut. 57.12, a codex containing the Epistolographi Graeci that was owned and annotated by Francesco Filelfo. The original nucleus of this composite was produced in Constantinople in the third decade of the 15th century. Afterwards, Filelfo himself had two copyists -one of whom is identifiable as Gerard of Patras - transcribe supplements to be added to the codex. Filelfo's ownership is proved not only by autograph (...) marginal notes, but also by the use of this manuscript as the source of Filelfo's Latin translation of several of these pseudepigraphic letters that were incorporated in his Commentationes Florentinae de Exilio, and by the correspondences between the marginalia accompanying the Commentationes and those in the Laur. Plut. 57.12. (shrink)

Selecting a large and diverse sample of 5–6-year-old preschool children, we aimed to extend previous findings on variability in children’s home math environment and its association with children’s mathematical skills. We operationalized mathematics in a broader way than in previous studies, by considering not only children’s numerical skills but also their patterning skills as integral components of early mathematical development. We investigated the effects of children’s gender and socioeconomic status on their home math environment, examined the associations between children’s home (...) math environment and their mathematical skills, and verified whether these associations were moderated by children’s gender and/or SES. Parents of 353 children completed a home math environment questionnaire and all children completed measures of their numerical and patterning skills. Results indicated no effect of children’s gender on their home math environment. There was no effect of SES on the performed home math activities, but small SES differences existed in parents’ math-related expectations and their attitudes. We found no evidence for associations between children’s home math environment and their mathematical skills. Furthermore, there were no moderating effects of gender or SES on these associations. One explanation for these findings might relate to the characteristics of the general preschool system in the country of the present study. Future studies should consider the effect of the preschool learning environment because it might explain differences between studies and countries with regard to the home math environment and its association with mathematical skills.

El artículo aborda en perspectiva el llamado visual turn producido en los estudios culturales: remonta la cuestión de una rivalidad entre la escritura y la imagen, estableciendo una cierta genealogía para este “enfrentamiento”. Para concluir, el trabajo finalmente recala en ciertos efectos que dicho giro visual tendrá sin duda en la reorganización de los campos de saber académicos.

Resumo: O objetivo do presente artigo é contrapor à acusação de tecnofóbico, erroneamente dirigida a Hans Jonas, a sua proposta de uma ethical turn da tecnologia, cujas bases estariam na capacidade ética de impor contenções ao avanço utópico do progresso técnico, algo que leva a ética da responsabilidade ao polêmico conceito de “heurística do temor”. Para tanto, parte-se de um exame sobre o projeto jonasiano de uma filosofia da tecnologia, cuja terceira perspectiva seria valorativa, sendo esta a que ele melhor (...) desenvolveu. A partir daí, analisa-se qual seria o valor da tecnologia, com base no ponto de vista da vida para então se examinar, estrategicamente, a posição de Gerard Lebrun, para quem Jonas estaria entre os filósofos tecnofóbicos. O intuito, nesse caso, é demonstrar a incoerência de tal interpretação, precisamente porque o pensador francês, com grande atuação no Brasil, confunde a proposta da reorientação ética com a imposição de um poder exterior, de cunho paralisante.: The purpose of this article is to counter against the accusation of technophobic, wrongly directed to Hans Jonas, his proposal for an ethical turn of technology, whose bases would be on the ethical capacity to impose restraint on the utopian advance of technical progress, something that leads to the ethics of responsibility to the controversial concept of “heuristic of fear”. To do so, we started from an examination of the Jonasian project of a philosophy of technology, whose third perspective would be valuable, which is the one he developed best. From there, we will analyze what would be the value of technology from the point of view of life and then strategically analyze the position of Gerard Lebrun for whom Jonas should be placed among technophobic philosophers. Our aim, in this case, is to demonstrate the inconsistency of such an interpretation, precisely because the French thinker with an important presence in Brazil, confuses the proposal of ethical reorientation with the imposition of an external power, of a paralyzing type.

The way students perceive a learning climate (e.g. controlling or stimulating) is significantly influenced by feedback and assessment. However, at present much is unclear about the relation between feedback and motivational state. More specifically, the interplay with student characteristics is unclear. Since there is a strong increase of group work, the central research question is what are the effects of positive, neutral or negative feedback presented to collaborating teams of students, on students? intrinsic motivation, performance and on group processes? One (...) hundred thirty?eight higher education students participated in this study. There were no significant differences in performance across conditions. Multi?level analysis enabled a detailed comparison between groups and individual members of groups. Amongst others, it was found that feelings of competence facilitate the effect of positive feedback at the group level, which suggests that positive feedback boosts interest especially in groups of highly competent students.

Resumo: O presente artigo tem como objetivo analisar três aspectos do tema do amor na obra de Friedrich Nietzsche. Para tanto, parte de dois pressupostos: [1] o sentimento do amor deve ser entendido como parte do projeto de crítica à metafísica e aos idealismos presentes na moral, na religião e na arte; e como consequência, [2] como crítica às noções do amor que remete à tradição socrático-platônico, judaico-cristã e moderna. Para tanto, os três aspectos daí derivados, mostram que o amor (...) em Nietzsche 1] não é falta, [2] nem negação de si, [3] nem está baseado na ideia de posse; muito pelo contrário, [1] amor é exuberância, [2] depende da fruição de si e [3] está baseado nas diferenças próprias e desigualdades naturais entre os indivíduos. Tal procedimento analítico chega à afirmação da amizade como amor superior, cujo conteúdo remente a um sentimento de homens nobres, precisamente aquilo que se poderia chamar, em Nietzsche, de um grande amor.: This article aims to analyze three aspects of the theme of love in Friedrich Nietzsche’s work. For that, it starts from two assumptions: [1] the feeling of love must be understood as part of the project of criticism of metaphysics and the idealisms present in morals, religion and art; and as a consequence, [2] as a critique of the notions of love that refer to the Socratic-Platonic, Judeo-Christian and modern tradition. The three aspects derived from it, show that love in Nietzsche [1] is not lack, [2] nor self-denial, [3] nor is it based on the idea of possession; quite the contrary, the opposite link, [1] love is exuberance, [2] depends on the enjoyment of oneself and [3] is based on self-differences and natural inequalities between individuals. Such an analytical procedure comes to the affirmation of friendship as a superior love, whose content refers to a feeling of noble men, precisely what could be called, in Nietzsche, great love.

RESUMO: Pretende-se, com este artigo, analisar como a noção de epistemologias do Sul possibilita pensar também em um ethos sulista, no sentido de que a crise ambiental que assola a civilização tecnológica, crescida sob os auspícios do saber científico moderno, acabou por levar ao maior impasse ético da história humana, aquele que põe em xeque a própria possibilidade de sua existência no futuro. Dessa forma, almeja-se analisar como as comunidades tradicionais representam a concretização fática daquilo que o filósofo alemão Hans (...) Jonas descreveu, em sua proposta de uma ética para a civilização tecnológica: um tipo de vida baseado na frugalidade e na temperança, diante da emergência da crise climática e da urgência de uma nova ética amparada na responsabilidade.: In this article we intend to analyze how the notion of epistemologies of the south enables us to think also of a southern ethos, in the sense that the environmental crisis that plagues the technological civilization, grown under the auspices of modern scientific knowledge ended up leading to the greatest impasse ethics of human history, one that calls into question the very possibility of its existence in the future. In this way, we intend to analyze how traditional communities represent the factual fulfillment of what the German philosopher Hans Jonas described in his proposal for an ethics for technological civilization: a type of life based on frugality and temperance in the face of the emergence of the climate crisis and the urgency of a new ethics based on responsibility.

Maladapting Minds discusses a number of reasons why philosophers of psychiatry should take an interest in evolutionary explanations of mental disorders and, more generally, in evolutionary thinking. First of all, there is the nascent field of evolutionary psychiatry. Unlike other psychiatrists, evolutionary psychiatrists engage with ultimate, rather than proximate, questions about mental illnesses. Being a young and youthful new discipline, evolutionary psychiatry allows for a nice case study in the philosophy of science. Secondly, philosophers of psychiatry have engaged with evolutionary (...) theory because evolutionary considerations are often said to play a role in defining the concept of mental disorder. The basic question here is: Can the concept of mental disorder be given an objective definition, or is it rather a normative concept? Thirdly and finally, evolutionary thinking in psychiatry has often been a source of inspiration for a philosophical view on human nature. Thus evolutionary psychiatrists have suggested, for example, that man's vulnerability to mental disorders may well be one of the defining features of our species. -/- Written by leading authors in philosophy, psychiatry, biology and psychology, this volume illustrates that many debates in contemporary philosophy of psychiatry are profoundly influenced by evolutionary approaches to mental disorders. Conversely, it also reveals how philosophers can help contribute to the burgeoning field of evolutionary psychiatry. It is important reading for a wide range of readers interested in mental health care and philosophy. (shrink)

This paper, which gives continuity to another article, analyzes the content of I Dialogus V, 14-22 and, in an appendix, presents our Portuguese translation of this excerpt. In these chapters, the Inceptor Venerabilis discusses whether St. Peter and the Roman Church possess primacy over all other apostles and churches; andwhether this primacy is granted by God himself. Ockham first presents, not ad litteram, the opinion of those who refute the thesis that Christ did not give primacy to Peter and the (...) Roman Church. Then, because this thesis fully deflates papal power, he proposes a contrary thesis based on five proofs. We conclude that Ockham’s unnamed opponent is Marsilius of Padua, whose opinions are in his Defensor Pacis. (shrink)

In three experiments, each of a set colour-unrelated distracting words was presented most often in a particular target print colour . In Experiment 1, half of the participants were told the word-colour contingencies in advance and half were not . The instructed group showed a larger learning effect. This instruction effect was fully explained by increases in subjective awareness with instruction. In Experiment 2, contingency instructions were again given, but no contingencies were actually present. Although many participants claimed to be (...) aware of these contingencies, they did not produce an instructed contingency effect. In Experiment 3, half of the participants were given contingency instructions that did not correspond to the correct contingencies. Participants with these false instructions learned the actual contingencies worse than controls. Collectively, our results suggest that conscious contingency knowledge might play a moderating role in the strength of implicit learning. (shrink)

Resumo Longe de pretender esgotar possíveis semelhanças entre Nietzsche e Quine, o texto que se segue tenciona mostrar, mediante comparações paradigmáticas e admissíveis convergências metodológicas, como ambos os autores, lançando mão de hipóteses naturalistas para interpretar o conhecimento e a estética, respectivamente, tornam possível pensar num naturalismo menos confinante e mais inventivo, livre dos prejuízos do cientificismo e mais condizente com a sensibilidade artística em geral.Far from intending to exhaust all the possible similarities between Nietzsche and Quine, the following text (...) aims at showing, through paradigmatic comparisons and admissible methodological convergences, how both authors - by making naturalistic assumptions to interpret knowledge and aesthetics respectively - allow us to think of a less confining and more creative naturalism, free from the prejudices of scientism and more compatible with the artistic sensibility in general.

Resumo O presente trabalho explora o expediente metodológico aplicado por Merleau-Ponty sobre a obra e a vida de Cézanne: a vida como exigência de uma obra. Discutimos como esse expediente oferece uma chave de leitura para as polêmicas relações entre a vida e a obra nietzschiana, tanto no sentido de verificar como Nietzsche se apresenta internamente à sua obra, quanto para analisar como as circunstâncias de sua vida podem ser interpretadas como exigências do tipo de obra que ele se propôs (...) a formular. Isso nos leva a uma nova estratégia para interpretar também a própria genealogia da obra nietzschiana e, com ele, de toda a história da filosofia.This paper explores the methodological expedient applied by Merleau-Ponty on the work and the life of Cézanne: the life as demand of a work. We discuss how this expedient offers a key to the controversial relations between Nietzsche’s life and Nietzsche’s work, both in terms of how Nietzsche presents himself internally in his work, and in analyzing how the circumstances of his life can be interpreted as demands of the kind of work he has set out to formulate. This brings us to a new strategy to interpret the genealogy of Nietzsche’s work and, with it, of the whole history of philosophy. (shrink)

Resumo: Pretende-se neste artigo analisar a noção nietzschiana de filósofo do futuro e sua contribuição para o surgimento do novo homem, tendo em vista, prioritariamente, Além de bem e mal. Para tanto, iniciaremos analisando de que forma esta obra pode ser considerada, segundo a pretensão de seu autor, como uma crítica da modernidade e, consequentemente, de que forma ela se constitui como o manifesto de uma tarefa que Nietzsche define como própria dos filósofos do futuro: a superação do passado, ou (...) seja, das formas metafísicas, dogmáticas e ascéticas que orientaram a filosofia ao longo da história, por meio dos “trabalhadores filosóficos”, que agora devem ceder lugar aos autênticos filósofos, cujas lentes fisiopsicológicas examinam o pensamento como sintoma da saúde ou da doença de seus autores. Com isso, Nietzsche substitui a antiga tarefa do filósofo por uma nova missão. Com essa reflexão, acredita-se margear alguns dos problemas centrais da pesquisa do homenageado desse dossiê, prof. Wilson Antonio Frezzatti Jr.: This paper intends to analyze the Nietzschean notion of philosopher of the future and its contribution to the emergence of the new man, having in mind, primarily, Beyond good and evil. In order to do so, we will begin by analyzing how this work can be considered, according to the author’s intention, as a critique of modernity and, consequently, in what way it constitutes the manifesto of a task that Nietzsche defines as proper to the philosophers of the future: the overcoming of the past, that is, of the metaphysical, dogmatic and ascetic forms that have guided philosophy throughout history, through the “philosophical workers”, who must now give way to authentic philosophers, whose physiopsychological lenses examine thought as symptom of the health or illness of its authors. With this, Nietzsche replaces the philosopher’s old task with a new mission. With this reflection, it is believed that some of the central problems of the research of the honoree of this dossier, prof. Wilson Antonio Frezzatti Jr., are bordered. (shrink)

The present paper aims at investigating the meaning and scope of the idea of musical dissonance in The Birth of Tragedy. In reviewing the possible explanatory definitions of this concept, within and outside the speculative-theoretical framework proper to Nietzsche’s first book, we hope to open a path that leads us to rethink the so-called “artist metaphysics”, and, specially, what is generally understood as Dionysian music.

Resumo: O propósito geral do presente texto consiste em introduzir o sentido e o alcance que noção de improvisação musical pode adquirir no filosofar nietzschiano, e, em especial, no assim chamado período de maturidade de seu itinerário intelectual. Tenciona-se indicar que tal ideia assume uma função reguladora em seu pensamento, possibilitando lançar uma intensiva luz sobre o seu legado e enfatizar, sobretudo, o caráter pluralista e dinâmico deste último.: The present text aims at introducing the meaning and the scope that (...) the notion of musical improvisation may acquire within Nietzsche’s thought - especially in the light of thehis latter writings. It also intends to show that such idea performs a regulatory function within his thought and allows us, at the same time, to shed a bright light on his legacy, serving first and foremost to emphasize its pluralistic and dynamic character.

Pretende-se com este artigo, demonstrar como o niilismo é um dos conceitos centrais da obra de Hans Jonas. Para isso, analisaremos como o problema se desdobra em sua obra a partir de três perspectivas complementares: a identificação de um niilismo cósmico, cujo primeira aparição são os movimentos gnósticos da Antiguidade tardia e seus impactos sobre o cristianismo primitivo; um niilismo antropológico derivado dessa posição gnóstica e agravado pela filosofia existencialista; um niilismo ético e tecnológico, que tanto serve para diagnosticar a (...) tecnologia como “vontade de ilimitado poder” quanto para compreender a crise ambiental a partir da crise de valores que marca o Ocidente a partir da modernidade. Com isso, o niilismo, interpretado como velle nihil, ou seja, como vontade de negação e, mais especificamente, de destruição, é uma chave interpretativa para a crise ambiental. Dessa forma, a obra de Jonas pode ser considerada como uma tentativa de evitar que o “mais estranho dos hóspedes” destrua a própria morada. (shrink)

Fall detection is a challenging task that has received the attention of the research community in the recent years. This study focuses on FD using data gathered from wearable devices with tri-axial accelerometers, developing a solution centered in elderly people living autonomously. This research includes three different ways to improve a FD method: an analysis of the event detection stage, comparing several alternatives, an evaluation of features to extract for each detected event and an appraisal of up to 6 different (...) clustering scenarios to split the samples in subsets that might enhance the classification. For each clustering scenario, a specific classification stage is defined. The experimentation includes publicly available simulated fall data sets. Results show the guidelines for defining a more robust and efficient FD method for on-wrist 3DACC wearable devices. (shrink)

The proposal that there is an illusion of conscious will has been supported by findings that priming of stimulus location in a task requiring judgements of action-authorship can enhance participants’ experience of agency. We attempted to replicate findings from the ‘Wheel of Fortune’ task [Aarts, H., Custers, R., & Wegner, D. M. . On the inference of personal authorship: enhancing experienced agency by priming effect information. Consciousness and Cognition, 14, 439–458]. We also examined participants’ performance on this task in relation (...) to self-reported passivity experiences and hallucination-proneness. We found a significant effect of priming, with primes being found to increase the experience of agency. An interaction between gender and priming was also found, with priming enhancing feelings of agency in women but not in men. There were no significant correlations between levels of self-reported passivity experiences or hallucination-proneness and participants’ susceptibility to the priming effect on ratings of agency. Implications of these findings are discussed with regard to a prominent model of passivity experiences. (shrink)
