O presente estudo tem por objetivo apresentar o cenário de “crise das ciências” pela qual a Europa atravessava no início do século XX, e a qual se refere Husserl nos seus textos mais tardios, situando-a num contexto que exigia urgentemente a elaboração de uma ciência capaz de dar rigor aos demais saberes científicos. Em seu desenvolvimento, destaca-se a relação entre a crise teórica dos fundamentos e o colapso da cultura ocidental, mostrando, como, para Husserl, a crise dos sentidos estava intimamente (...) ligada ao advento da ciência moderna que, historicamente, desenvolveu-se no positivismo. Por meio de uma pesquisa panorâmica dos movimentos positivistas da modernidade, apontamos, finalmente, para o contrassenso no modelo das Ciências do Espírito enquanto executoras de uma metodologia científico-natural, que, por sua vez, mostra-se extremamente nociva ao desenvolvimento espiritual da humanidade ocidental.

We conducted a rapid review and quantitative summary of meta-analyses that have examined interventions which can be used by individuals during quarantine and social distancing to manage anxiety, depression, stress and subjective well-being. A literature search yielded 34 meta-analyses (total number of studies k = 1,390, n = 145,744) that were summarized. Overall, self-guided interventions showed small to medium effects in comparison to control groups. In particular, self-guided therapeutic approaches (including cognitive-behavioral, mindfulness, and acceptance-based interventions), selected positive psychology interventions, and (...) multi-component and activity-based interventions (music, physical exercise) showed promising evidence for effectiveness. Overall, self-guided interventions on average did not show the same degree of effectiveness as traditional guided individual or group therapies. There was no consistent evidence of dose effects, baseline differences and differential effectiveness of eHealth interventions. More research on the effectiveness of interventions in diverse cultural settings is needed. (shrink)

This text presents an analysis of a collection of Mathematics textbooks, carried out for the discipline “Analysis of Mathematics Books and Teaching Materials”, taught in the Graduate Program in Mathematics Education at the Universidade Estadual Paulista “Júlio de Mesquita Filho”. Inspired by the methodology of vertical and horizontal analysis of textbooks, this work aims to understand in what ways the law 10.639/2003 is effective in textbooks that satisfy the demands of the New High School and the BNCC – Base (...) Nacional Comum Curricular. Presenting the historical movements of black populations, mainly the Brazilian one, the text is inspired by the two decades of that law to conduct the analysis criteria and seek to understand in what ways the analyzed collection acts in the constitution of the mathematical identity of black students. At the end of the analysis, it is observed that the law is barely complied with, speaking through erasures and without delving into important points about racial discussions. It is concluded that changes are necessary for compliance with the law to produce positive effects on the constitution of mathematical identities of black subjects. (shrink)

Em O Homem-Máquina, La Mettrie, trata da materialidade da alma e do corpo como uma máquina destinada a felicidade. Há nesse argumento um enfrentamento diante da compreensão da alma ser distinta dele, onde o médico-filósofo descreve que ela, como toda parte do corpo, seria afetada. O movimento do sangue no corpo a alcança e, quando o corpo dorme, ela dorme com ele. Esse argumento constitui o ponto de partida da presente exposição, que tem como objetivo compreender a origem do remorso (...) em seu pensamento, se apresentando como uma reminiscência, como o resultado da experiência vivida. Em Anti-Sêneca ou Discurso sobre a Felicidade, o filósofo descreve a atuação da moral na máquina, de onde se propõe demonstrar o sentimento do remorso como um preconceito a ser combatido para o seu bom funcionamento. Cumpre demonstrar, a partir de uma revisão bibliográfica sobre o tema no pensamento de La Mettrie, o sentimento de remorso e de sua origem, pois ao naturalizar a alma humana, justifica ser o remorso um sentimento adquirido e alheio a máquina.

While human rights law has evolved to provide guidance to governments in realizing human rights in public health emergencies, the COVID-19 pandemic has challenged the foundations of human rights in global health governance. Public health responses to the pandemic have undermined international human rights obligations to realize the rights to health and life, human rights that underlie public health, and international assistance and cooperation. As governments prepare for revisions of global health law, new opportunities are presented to harmonize global health (...) law and human rights law, strengthening rights-based governance to respond to future threats.

We argue that emotion cannot only be conceived of as a short-lived and intrapersonal phenomenon. Rather, based on five theoretical arguments, we propose that the social sharing of an emotional experience forms an integral part of the emotional processes. A series of six studies investigated different aspects of this hypothesis. Study 1 showed that an overwhelming majority of people reported sharing their emotional experiences and that the memories of these experiences tended to come back spontaneously to their consciousness. No difference (...) was found among emotions. Using a different procedure, Studies 2 and 3 replicated these findings in two different populations. In addition, these studies provided indications that women share their experiences with a wider array of individuals than do men. The first three studies did not find any differences among emotions, but they did not include shame. It could be argued that people are less inclined to socially share shame experiences which are typically elicited by breaking social rules. Study 4 specifically investigated this hypothesis. No differences among shame and other emotions were found except for the delay of the first sharing of the experience. Study 5 constituted a first investigation of whether the social sharing of emotion is also a significant process in now Western cultures. A comparison between Dutch and Surinamese people failed to reveal any significant difference. Based on the findings of the first five studies, a correlational model was designed in Study 6. It tested the interrelationships among disruptiveness of the emotion, social sharing, mental rumination, and recovery from the emotion disruption. A coherent pattern of findings emerged, showing that social sharing can be conceived as a bi-dimensional concept defined by features of amount and delay of sharing. In addition, both social sharing and mental rumination varied according to the disruptiveness of the emotion. Surprisingly, however, recovery could not be related to social sharing, mental rumination, or to the time elapsed since the episode. (shrink)

RESUMO Os homens, por natureza, desejam conhecer. Sinal disso é o prazer que nos proporcionam os nossos sentidos, pois ainda que não levemos em conta suas utilidades são estimados por si mesmos, destacando-se acima de todos os outros o sentido da visão. Segundo Platão, esta preocupação filosófica sempre foi a razão de ser da filosofia porque o filosofo, amante do conhecimento, busca sempre a verdade. Ele ama o saber. A busca do saber interior exige do filósofo não qualquer conhecimento, mas (...) somente aquele que ele considera como verdadeiro. Invocando as ideias acima externadas, este artigo traduz o expresso objetivo de iluminar os caminhos do leitor na busca desse conhecimento. (shrink)

Frente uma situação sócio-cultural, eclesial e societária onde vive-se a falta de liberdade criativa e de uma ação ousada, alternativa e esperançosa, Paulo parece apontar caminho, à luz do Evangelho da liberdade, para uma experiência nova e prometedora. O que importa é assumir com responsabilidade a Vida e superar toda "escravidão", vale dizer, o que vale é viver em liberdade na experiência do amor diante do império da impotência e da morte. A experiência da fé tem que levar ao agir (...) ético que revele uma vida livre e construtora de uma nova realidade de vida, relacionamento e compromisso no atual contexto. (shrink)

O presente artigo apresenta a distinta teoria do conhecimento proposta por Walter Benjamin em seu projeto das Passagens. Tal proposta já encontra suas origens em seus textos de juventude, principalmente em seu Sobre o programa de uma filosofia vindoura. Levando isso em conta, articulamos os dois momentos da obra de Benjamin para demonstrar que esta nova teoria materialista, dialética e imagética do conhecimento pressupõe um conceito mais alto de experiência, assim como uma crítica contundente ao sujeito do conhecimento que se (...) encontra em vias de desagregação. Para nos aprofundarmos na proposição benjaminiana, adentramos a importante topografia conceitual presente nas Passagens, passando pelos temas da linguagem, do sonho, do despertar e das imagens dialéticas.

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.

Partindo da controvérsia Henrich-Habermas dos anos 1980, este artigo discute a possibilidade de conservar um espaço aberto para a metafísica, na filosofia atual, tendo em vista o modo como Kant reformulou esse campo do saber. Procurando levar a sério a intenção kantiana, eu me baseio nas reflexões do próprio Dieter Henrich e de Christian Thies para apresentar, em linhas muito gerais, um possível formato para essa nova forma de metafísica.

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.

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.

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.

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. (shrink)

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.

Translation of passages of Aristotle's De Anima into Portuguese. The passages are these: I.1, I.4 (the 'Rylean passage'); II.1-6; III.1-8. The translation is preliminary.

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.

This article aims to examine the possibility to explain the basis of moral behaviour in natural terms consistent with evolutionary theory. The defense position begins with the clarification of the concept of empathy, as done by Hume and Darwin, plus contemporary research in the areas of neuroscience, evolutionary psychology and ethology. My argument points in favor of the hypothesis that socially relevant emotions are regulators of social behaviour, being a criterion for distinguishing between moral and purely social relations. What should (...) be understood is in that bases psychobiological mechanisms of sociability, particularly empathy and social instincts, operate as regulators of normative behaviour in small groups and how this relates to the way moral distinctions are made in everyday life. The focus of this investigation will be to identify the elements that are at the root of such behaviour and explain it without resorting to metaphysical concepts. I will present empathy as the candidate to answer the question of how these mechanisms developed within the evolutionary process and how to add an intersubjective element to social relevant emotions, so that they have the strength to inhibit socially relevant behaviours. Key-Words: Empathy. Social Instincts. Moral Behaviour. (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. My central focus is not to discuss whether Aristotle is prescribing and using what has been called the method of endoxa. 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.

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.

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 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".

Joint attention customarily refers to the coordinated focus of attention between two or more individuals on a common object or event, where it is mutually “open” to all attenders that they are so engaged. We identify two broad approaches to analyse joint attention, one in terms of cognitive notions like common knowledge and common awareness, and one according to which joint attention is fundamentally a primitive phenomenon of sensory experience. John Campbell’s relational theory is a prominent representative of the latter (...) approach, and the main focus of this paper. We argue that Campbell’s theory is problematic for a variety of reasons, through which runs a common thread: most of the problems that the theory is faced with arise from the relational view of perception that he endorses, and, more generally, they suggest that perceptual experience is not sufficient for an analysis of joint attention.

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 the contrast between scientific knowledge and opinion as it is presented by Aristotle in Posterior Analytics A.33. Aristotle's contrast is formulated in terms of understanding or not understanding some "necessary items". I claim that the contrast can only be understood in terms of explanatory relevance. The "necessary items" are middle terms (or explanatory factors) that are necessary for the fully appropriate explanation. This approach gives a coherent interpretation of each step in the chapter.

These are commentaries to the translation into Portuguese of Nicomachean Ethics VI, found in the same volume of Dissertatio.

Affective experiences such as pains, pleasures, and emotions have affective phenomenology: they feel pleasant. This type of phenomenology has a loopy regulatory profile: it often motivates us to act a certain way, and these actions typically end up regulating our affective experiences back. For example, the pleasure you get by tasting your morning coffee motivates you to drink more of it, and this in turn results in you obtaining another pleasant gustatory experience. In this article, we argue that reflexive imperativism (...) is the only intentionalist account of affective phenomenology—probably, the only account at all—that is able to make sense of its loopy regulatory profile.

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.

I discuss Aristotle's treatment of essence and definition in Metaphysics VII.4. I argue that it is coherent and perfectly in accord with its broader context. His discussion in VII.4 offers, on the one hand, minimal criteria for what counts as definition and essence for whatever kind of object, but also, on the other hand, stronger criteria for a primary sort of definition and essence—and thereby it serves the interest of book VII in pointing to the explanatory power of the essence (...) of composite substances.

O presente artigo tem como objetivo estabelecer o papel que a constituição biológica de mamíferos e as construções culturais têm na expressão de emoções sociais básicas. A relevância social das emoções será investigada a partir da discussão entre o evolucionismo e o construtivismo, com enfoque no papel dos movimentos expressivos na sua comunicação em diferentes espécies de animais e culturas humanas. O estudo relativo às expressões emocionais será realizado mediante a apresentação dos princípios gerais das emoções desenvolvidos por Darwin em (...) combinação com análises contemporâneas realizadas pelas ciências naturais sobre o tema. Como estudo de caso, será apresentada a pesquisa desenvolvida por Tracy e Matsumoto, onde é realizada uma comparação das expressões de orgulho e vergonha em humanos com visão normal e cegueira congênita. O argumento é que, caso estes princípios sejam homólogos em diferentes espécies ou, ainda, expressos da mesma forma em humanos incapazes de mimetiza-los pelo olhar, então uma explicação evolucionista sobre a relação entre emoções e comportamento tende a ganhar força.Palavras-chave: Emoções. Expressão. Naturalismo. Evolucionismo. Construtivismo. (shrink)

Philip E. Tetlock and I agree that forecasting tools are best evaluated in peer-reviewed settings and in comparison not only to expert judgments, but also to alternative modeling strategies. Applying his suggested standards of assessment, however, certain forecasting models not only outperform expert judgments, but also have gone head-to-head with alternative models and outperformed them. This track record demonstrates the capability to make significant, reliable predictions of difficult, complex events. The record has unfolded, contrary to Tetlock's contention, not only in (...) government and business applications, but also in numerous peer-reviewed publications containing hundreds of real-time forecasts. Moreover, reliable prediction is achieved while avoiding significant false-positive or false-negative rates. (shrink)

Este artigo tem como objetivo um olhar histórico-teológico para a reflexão do mistério pascal principalmente no que diz respeito à questão celebrativa. No caminhar de dois milênios é notória a divisão deste tema em dois momentos: No primeiro milênio a força teológico-celebrativa do mistério pascal. No segundo milênio o caminho mudou sua rota com atitudes que levaram a se distanciar da proposta inicial na sua teologia e na sua celebração. O Concílio Vaticano II, momento eclesial de extrema importância tenta retomar (...) o caminho desviado e propõe uma volta às fontes a fim de que o mistério celebrado seja realmente o mistério de Jesus, ou seja, o Mistério Pascal na sua originalidade e inteireza. Vale lembrar que esta reflexão e também a liturgia não esgotam o tema. A teologia em seus desdobramentos e sua amplitude tem um vasto campo para sempre mais ajudar a refletir e celebrar este mistério. (shrink)

In contrast to most current approaches to international politics, this work views domestic politics and international relations as inseparable and the role of individual political leaders as key. A core assumption is that political leaders and foreign policy decision makers are motivated to keep their jobs and that they select policies and allocate scarce resources so as to help them fulfill their personal political objectives.

The initial problem to be faced by naturalist investigations into morals is how to conceptualize it in a way that explains what ordinarily occurs in nature. In this sense, a vertical explication where actions are catalogued according to abstract theoretical constructions says little about the world. Therefore, the investigation presented in this article will be guided by an inverse methodology. It will refer to analysis of ordinary social behaviours which I will advance through the understanding of morality according to its (...) functionality. The concept of morals presented by Tugendhat, for whom morality is a combination of reciprocal demands expressed through sentences of duty based on sentiments, is of major importance to the way in which I will address the question. Moreover, I will carry out an accurate study of humean moral thought, with the objective of determining to what extent sentiment and reason influence the motivation to approve or censor socially relevant actions. Once we have investigated the natural aspects of the moral phenomenon, I will conclude the article presenting a possible compatibility between theoretical marks of humean empiricism and Darwin’s evolutionism.

Computer vision research involving street and road detection methods usually focuses on driving assistance and autonomous vehicle systems. In this context, street segmentation occurs in real-time, based on images centered on the street. This work, on the other hand, uses street segmentation for urban planning research to classify pavement types of a city or region, which is particularly important for developing countries. For this application, it is needed a dataset with images from various locations for each street. These images are (...) not necessarily centered on the street and include challenges that are not common in street segmentation datasets, such as mixed pavement types and the presence of faults and holes on the street. We implemented a multi-class version of a state-of-the-art segmentation algorithm and adapted it to perform street pavement classification, handling navigation along streets and angle variation to increase the accuracy of the classification. A data augmentation approach is also proposed to use preliminary results from the test instances as new ground truth and increase the amount of training data. A dataset with more than 300,000 images from 773 streets from a Brazilian city was built. Our approach achieved a precision of 0.93, showing the feasibility of the proposed application. (shrink)

This book discusses Aristotle’s notions of essence and substance as they are developed in Metaphysics ZH. I examine Aristotle's argument at length and defends an unorthodox interpretation according to which his motivation is to provide an answer against a conflation between criteria for existential priority (delivering substances as primary beings) and criteria for explanatory priority (delivering essences as primary principles).

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 “sujeito” (“subject”).
