We argue that the true nature of the renormalizability of Horava-Lifshitz gravity lies in the presence of higher order spatial derivatives and not in the anisotropic Lifshitz scaling of space and time. We discuss the possibility of constructing a higher order spatial derivatives model that has the same renormalization properties of Horava-Lifshitz gravity but that does not make use of the Lifshitz scaling. In addition, the state-of-the-art of the Lorentz symmetry restoration in Horava-Lifshitz-type theories of gravitation is reviewed.

En este breve comentario discuto algunos aspectos de la interpretación de la epistemología de Davidson que sugiere Willian Duica en su reciente libro. Luego de una presentación somera del libro me centro en tres asuntos centrales de la interpretación de Duica. En primer lugar, argumento que su lectura de la crítica de Davidson al dualismo esquema/contenido es muy restrictiva y deja abierta la posibilidad de un realismo directo empirista. En segundo lugar, argumento que en su lectura el propio Duica se (...) compromete inadvertidamente con un empirismo de este tipo y, de este modo, su interpretación entra en tensión con el coherentismo de Davidson. Finalmente, discuto algunos aspectos de la interpretación que hace Duica de la tesis davidsoniana de la triangulación. In this short comment I discuss some aspects of William Duica's interpretation of Davidson's epistemology in a recent book. After a brief review of the book, I focus on three central issues of Duica's interpretation. First, I argue that his reading of Davidson's criticism of the scheme/content dualism is too restrictive and leaves open the possibility of an empiricist direct realism. Second, I argue in his reading Duica inadvertently commits himself to an empiricism of this sort and, as a result, his interpretation is in tension with Davidson's own coherentism. Finally, I discuss some aspects of Duica's interpretation of Davidsonian triangulation. (shrink)

O artigo empreende uma discussão sobre o conceito de Formação Cultural (Bildung) em G. W. F. Hegel (1770-1831), buscando apreender como o filósofo aborda a educação em suas obras. Para tal, analiso a perspectiva hegeliana de solução ao problema pedagógico, a saber, “Qual a melhor forma de educar o homem?”, imposto a todo e qualquer projeto educacional. Através de uma leitura de textos da Fenomenologia do Espírito (1807), dos Discursos sobre Educação (1808-1816), e da Filosofia do Direito (1821), viso apreender (...) o conceito de Formação Cultural em seu sistema filosófico.

Em diálogo com Paulo Freire, o artigo enfatiza a condição sine qua non de existir ética para haver docência, afirmando ainda que a ética pode ser ensinada, mas não com base apenas em conceitos, pois somente através da interação e do reconhecer da alteridade pode o professor assumir uma atitude ética, sendo autônomo e gerando autonomia.

Este artículo presenta una interpretación del ser-para-otro en la ontología fenomenológica de Sartre. A partir de un análisis contextual de la fenomenología de la mirada en El ser y la nada, formulamos el problema del ser-para-otro como tercera ek-stasis. Si admitimos que el ser-para-otro surge de una profundización de la segunda ek-stasis (reflexión) y que, por tanto, está siempre condicionado por ella, corremos el riesgo de caer en la ilusión de la primacía del ser-para-sí. En oposición a esta interpretación, presentamos (...) la hipótesis de que el ser para otro tiene una estructura inmediata, y no sólo reflexiva, basada en El ser y la nada y, de manera auxiliar, en el Idiota da familia.

As state-of-art technology can create artificial images that are indistinguishable from real ones, it is urgent to understand whether believing that a picture is real or not has some import over affective phenomena such as sexual arousal. Thus, in two pre-registered online studies, we tested whether 60 images depicting models in underwear elicited higher self-reported sexual arousal when believed to be (N = 57) or presented as (N = 108) real photographs as opposed to artificially generated. In both cases, Realness (...) correlated with significantly higher scores on self-reported sexual arousal. Consistently with the literature on downregulation of emotional response to fictional works, our result indicates that sexual images that are perceived to be fake are less arousing than those believed to portray real people.

Com este artigo se pretende passar pelas leituras feitas sobre o texto do profeta Zacarias. Não há a intenção de se fazer uma abordagem exegética, mas antes, apenas um histórico da pesquisa do profeta - tão pouco lido no Brasil e na América Latina. Sua relevância conduz ao conhecimento das posições e propostas mais clássicas e as mais inovadoras da interpretação deste texto profético. Como também reconhecendo as últimas dificuldades encontradas na sua interpretação.

Com este artigo, pretendeu-se problematizar a integração da hipermídia educacional, nas Atividades de Estudo a Distância (AEDs), como possibilidade de potencializar a interação mediada por computador. Dessa forma, foram apresentadas algumas estratégias que embasaram o planejamento, a organização e a implementação de uma AED mediada pelo Modular Object-Oriented Dynamic Learning Environment (Moodle). Assim, observou-se que é essencial que as AEDs sejam planejadas e organizadas didaticamente pelo professor, que define quais propósitos pretende alcançar no contexto de ensino e aprendizagem mediado pelas (...) Tecnologias da Informação e Comunicação (TICs), pois, elaborar uma AED hipermidiática e guiar seu desenvolvimento, tanto com relação à tecnologia quanto ao próprio conteúdo em questão, colabora na proposição de alternativas para resolvê-las e também possibilita uma maior interação entre os envolvidos (professor e alunos) na apropriação crítica do conhecimento escolar, o que contribui para a sustentabilidade do processo ensino e aprendizagem significativo e interativo para todos os envolvidos.

O artigo reflete sobre o procedimento hermenêutico utilizado pelo professor, crítico e filósofo Benedito Nunes em sua obra. Reconstruindo diálogos do autor com Nunes, procura-se compreender as peculiaridades da sua abordagem interpretativa em relação a três pensadores com os quais sua obra dialoga em permanência, Heidegger, Gadamer e Ricoeur. Compreende- se que a abordagem de Nunes procura superar alguns impasses da hermenêutica contemporânea por meio da problemática heideggeriana da co-referencialidade entre fundamento e abismo, tema presente na questão geral do conflito (...) ôntico ontológico, compreendendo-se fundamento como aquilo que é a fundamentação do ser relativamente ao ente, e abismo como o ser enquanto tal. A partir dessa equação, considerando o estatuto da co-presença (Zusammengeböririgkeit) entre os dois elementos, entende-se que a ação de interpretação de Nunes valoriza não apenas as dinâmicas de desvelamento, mas também de ocultamento do ser e, em o fazendo, permite uma abertura da hermenêutica para a alteridade.

O presente artigo propõe uma análise dos riscos de degeneração da democracia contemporânea em três pontos. No primeiro ponto, retomamos o tema da possibilidade de degeneração da democracia segundo a perspectiva de Platão e Aristóteles com o objetivo de apresentar os seus traços elementares. No segundo ponto, fazemos uma análise do pensamento de Alexis de Tocqueville, particularmente do modo como ele tratou as ameaças à democracia no quadro do liberalismo político do século XIX. Procuramos mostrar, em um terceiro ponto, que (...) o cenário contemporâneo exige que se coloquem em relevo os efeitos produzidos pelas novas mídias e pelo retorno de um discurso totalitário. Utilizamos, para tanto, alguns textos escolhidos de Baudrillard e Rancière, na tentativa de melhor explicitar o modo como as ameaças atuais à democracia se entrelaçam à sociedade de consumo, às novas mídias e ao retorno de um discurso totalitário. Palavras-chave: Democracia. Tirania. Atomização social. Totalitarismo. (shrink)

Fábio Alves dos Santos (1954-2013) cursou Pedagogia, Ciências Sociais e Teologia, era Especialista em Filosofia da Religião (PUC Minas), Advogado (PUC Minas) e Mestre em Direito Constitucional (UFMG). Lecionou na PUC Minas como professor de Cultura Religiosa e depois como professor no Curso de Direito, atuando principalmente no Serviço de Assistência Judiciária – SAJ, especialmente cuidado de causas populares como as da ASMARE (Associação dos Catadores de Papel, Papelão e Material Reaproveitável de Belo Horizonte), da Pastoral de Rua, da Pastoral (...) Carcerária, de movimentos de “Sem Casa”, de ocupações e tantos outros grupos. Fábio sofria de grave problema de visão há mais de 15 anos. Quase ficou cego depois de diversas cirurgias de miopia. Isso, porém, não o impedia de seguir seu constante compromisso com as lutas populares. Na última entrevista que concedeu, menos de um mês antes de sua morte (19 de outubro de 2013), depois de duro sofrimento de quase dois anos, no tratamento de um câncer no pâncreas, conta um pouco de sua vida, sua luta e sua percepção de várias realidades, especialmente da Igreja e da pastoral. Militante formado na Teologia da Libertação, de profunda espiritualidade, marcada por traços da religiosidade popular nordestina e comprometida com a libertação, Fábio Alves também buscou em sua vida abrir-se à teologia do pluralismo religioso, especialmente com o Santo Daime, em cuja tradição religiosa chegou a ser “fardado”, mantendo uma profunda atitude espiritual aberta ao diálogo inter-religioso. Sua primeira publicação foi “Começo de mundo novo: sofrimento, luta e vitória dos posseiros de Santana dos Frades”, Sergipe, numa versão popular em 1981 e outra pela Editora Vozes (1990). Fruto de sua dissertação de mestrado, publicou o livro “Direito Agrário: política fundiária no Brasil (1995). Em 2001 saiu seu último livro, uma coletânea de artigos publicados em diversos jornais: “Em defesa da vida”. Num artigo em Horizonte (2004), juntamente com o advogado, amigo e colega Prof. Cristiano de Melo Bastos, discutiu “A prática jurídica na missão da PUC Minas”.

A critical review of the main themes arising out of recent literature on the semantics of ordinary event talk. The material is organized in four sections: (i) the nature of events, with emphasis on the opposition between events as particulars and events as universals; (ii) identity and indeterminacy, with emphasis on the unifier/multiplier controversy; (iii) events and logical form, with emphasis on Davidson’s treatment of the form of action sentences; (iv) linguistic applications, with emphasis on issues concerning aspectual phenomena, the (...) telicity/atelicity distinction, the treatment of statives, and temporal quantification.

Enthymemes are traditionally defined as arguments in which some elements are left unstated. It is an empirical fact that enthymemes are both enormously frequent and appropriately understood in everyday argumentation. Why is it so? We outline an answer that dispenses with the so called "principle of charity", which is the standard notion underlying most works on enthymemes. In contrast, we suggest that a different force drives enthymematic argumentation—namely, parsimony, i.e. the tendency to optimize resource consumption, in light of the agent's (...) goals. On this view, the frequent use of enthymemes does not indicate sub-optimal performance of arguers, requiring appeals to charity for their redemption. On the contrary, it is seen as a highly adaptive argumentation strategy, given the need of everyday reasoners to optimize their cognitive resources. Considerations of parsimony also affect enthymeme reconstruction, i.e. the process by which the interpreter makes sense of the speaker's enthymemes. Far from being driven by any pro-social cooperative instinct, interpretative efforts are aimed at extracting valuable information at reasonable costs from available sources. Thus, there is a tension between parsimony and charity, insofar as the former is a non-social constraint for self-regulation of one's behaviour, whereas the latter implies a pro-social attitude. We will argue that some versions of charity are untenable for enthymeme interpretation, while others are compatible with the view defended here, but still require parsimony to expose the ultimate reasons upon which a presumption of fair treatment in enthymeme reconstruction is founded.

In this paper we present tableau methods for two-dimensional modal logics. Although models for such logics are well known, proof systems remain rather unexplored as most of their developments have been purely axiomatic. The logics herein considered contain first-order quantifiers with identity, and all the formulas in the language are doubly-indexed in the proof systems, with the upper indices intuitively representing the actual or reference worlds, and the lower indices representing worlds of evaluation—first and second dimensions, respectively. The tableaux modulate (...) over different notions of validity such as local, general, and diagonal, besides being general enough for several two-dimensional logics proposed in the literature. We also motivate the introduction of a new operator into two-dimensional languages and explore some of the philosophical questions raised by it concerning the relations there are between actuality, necessity, and the a priori, that seem to undermine traditional intuitive interpretations of two-dimensional operators.

We are used to regarding actions and other events, such as Brutus’ stabbing of Caesar or the sinking of the Titanic, as occupying intervals of some underlying linearly ordered temporal dimension. This attitude is so natural and compelling that one is tempted to disregard the obvious difference between time periods and actual happenings in favor of the former: events become mere “intervals cum description”.1 On the other hand, in ordinary circumstances the point of talking about time is to talk about (...) what actually happens or might happen at some time or another. We talk about ‘now’ and ‘then’ in an effort to put some order in our description of what goes on. And since different events seem to overlap in so many different ways, a full account of their temporal relations seems to run afoul of a reductionist strategy. This raises two philosophical questions. The first is whether we can actually go beyond time, as it were, i.e., whether we can take events as bona fide entities and deal with them directly, just as we can deal with spatial entities such as physical bodies or masses without confining ourselves to their spatial representations. This is a controversial issue (though probably not as controversial as it used to be), and ties in with a number of unsettled problems concerning, e.g., the structure of causality or the definition of adequate identity and individuation criteria for events. 2 The second question is whether we can perhaps do without time, i.e., whether we can dispense with time points or intervals as an independent ontological category and focus only on actual or potential happenings, in opposition to the form of reductionism mentioned above—in short, whether we can account for the temporal dimension in terms of suitable relations among events. This is also a highly controversial issue, and relates to the classical dispute concerning relational vs. absolutist conceptions of (space and) time.3 It is this second question that we intend to focus on here..

Focused on city-scale automation, and using self-driving cars (SDCs) as a case study, this article reflects on the role of AI—and in particular, computer vision systems used for mapping and navigation—as a catalyst for urban transformation. Urban research commonly presents AI and cities as having a one-way cause-and-effect relationship, giving undue weight to AI’s impact on cities and overlooking the role of cities in shaping AI. Working at the intersection of data science and social research, this paper aims to counter (...) this trend by exploring the reverse perspective: how do cities affect the development, and expose the present limits, of SDCs? The contribution of this paper is threefold. First, by comparing urban and nonurban environments and thoroughly examining the relationship between computer vision and city-specific sociality and form, it defines machine autonomy/automation as a function of the sociotechnical milieu in which an AI system operates. Second, and related, the paper problematizes the notion of SDCs as autonomous technologies and the role it plays in envisioning contending policy arrangements and technical solutions for achieving full driving automation. Finally, the article offers insight into a materialist and spatialized understanding of AI—namely, not as an abstract quality susceptible to replication within discrete machines, but rather as a distributed property emerging through embodied interactions among a multiplicity of agents (human, non-human, and technological) within/with their environments.

Populism is widely thought to be in tension with liberal democracy. This article clarifies what exactly is problematic about populism from a liberal–democratic point of view and goes on to develop normative standards that allow us to distinguish between more and less legitimate forms of populism. The point of this exercise is not to dismiss populism in toto; the article strives for a more subtle result, namely, to show that liberal democracy can accommodate populism provided that the latter conforms to (...) particular discursive norms. What the article calls a ‘liberal ethics of populism’ turns out to be closely bound up with a broader ethics of peoplehood, understood as a way of articulating who ‘the people’ are in a way that is compatible with liberal–democratic principles of political justification. Such an ethics, concludes the article, inevitably has a much wider audience than populist political actors: its addressees are all those who seek legitimately to exercise power in the name of the people.

ABSTRACT The article deals with the early career of the literary critic Alberto Asor Rosa, one of the founders of the operaismo movement, a Marxist tendency advocating the management of factories by workers through bottom-up councils. It outlines the role he assigned to literature and culture, investigating his criticism first against the non-revolutionary cultural politics of the Italian Communist Party, notoriously through his book Scrittori e popolo and his writings for the periodical classe operaia, then identifying a transition from a (...) destructive approach against any culture based on values to the use of cultural disciplines purely as techniques. The article posits that this instrumental understanding of culture depended on Asor Rosa’s political choice to take the perspective of the working class, in order to use culture itself for social analysis. In the second half of the decade, contributing to the periodicals Angelus novus and Contropiano, he still considered culture ineffective as a way towards revolution, but he began to value the great works of ʻbourgeois’ literature for their ability to penetrate the middle-class spirit and undermine capitalist society. The article concludes that, despite his changing idea of culture, Asor Rosa’s opinions on the intellectual’s task fit the traditional concept of it. (shrink)

RESUMO: O objetivo deste artigo é examinar o que entendemos ser uma prova original da existência de Deus na obra de Pierre Duhem. Cremos que a originalidade dessa prova consiste especialmente nas premissas usadas pelo filósofo. Quanto à forma, a mesma assemelha-se ao conhecido argumento do desígnio, mas a sua versão se caracteriza por buscar na história das teorias físicas a matéria da qual a existência de uma Providência é derivada. É a complexa evolução das teorias e, a despeito dela, (...) a sua espantosa progressividade em direção a estágios sempre mais perfeitos que servem de premissa para a via duhemiana de acesso a Deus. Tudo se passa como se houvesse uma suposta pré-ordenação divina do curso das teorias, uma finalidade intrínseca a ele.ABSTRACT: The aim of this paper is to examine what we believe to be an original proof of the existence of God in the work of Pierre Duhem. We think that the originality of this proof consists especially in the assumptions used by the French philosopher in his argumentation. Regarding the form, it resembles the well-known design argument, but his version is characterized by seeking in the history of physical theories the matter from which the existence of a Providence is derived. It is the complex evolution of theories and, despite it, its amazing progress towards ever more perfect theories that serves as the premise for Duhem's way of access to God. Everything goes as if it had been a divine preordainment and an intrinsic goal ruling the evolution of theories. (shrink)

Populist movements have become key players in European politics. These movements are readily criticized by journalists or political rivals, yet none of the common objections to populism seems to arrest their success. This article turns to normative political theory to cultivate sensitivity to problems arising from some existing arguments against populism, and to explore possible alternatives. It offers a critical reading of prototypical liberal and conservative arguments against populism, and proposes that the principles of solidarity and procedure provide good grounds (...) for a sustainable critique of populism.

This article, Piaget’s theory of moral development in play behaviour is critically reviewed and framed within the philosophical debate on morality. On this basis, an alternative socio-cognitive model for describing normative evolution in play development is proposed. Special attention is paid to the transition from children’s play to adult games, for the purpose of demonstrating that some relevant features of morality stagnate, rather than progress, during such transition. Finally, some speculations are offered on the connection between moral involution in play (...) and ethical behaviour in life, with reference to contemporary Western societies. (shrink)

The aim of this article is to present and discuss the language of the «givens», a typical stylistic resource of Greek mathematics and one of the major features of the proof format of analysis and synthesis. I shall analyze its expressive function and its peculiarities, as well as its general role as a deductive tool, explaining at the same time its particular applications in subgenres of a geometrical proposition like the locus theorems and the so-called «porisms». The main interpretative theses (...) of this study are the following: the language of the «givens» (1) is the standard idiom in which “existence and uniqueness” of a mathematical object was proved, (2) was conceived as an unified framework reducing to a strictly deductive format disparate argumentative steps such as deductions, constructions, and calculations.

Virtue argumentation theory has been charged of being incomplete, given its alleged inability to account for argument cogency in virtue-theoretical terms. Instead of defending VAT against that challenge, I suggest it is misplaced, since it is based on a premise VAT does not endorse, and raises an issue that most versions of VAT need not consider problematic. This in turn allows distinguishing several varieties of VAT, and clarifying what really matters for them.

What things mean to us involves more than what they afford in a straightforward sense (e.g., motor affordances). One can think of bodily adornments, lines, or precious stones. Differently from tools like hammers, these things are used to be displayed, watched etc. The paper investigates this very important feature of human behaviour, focusing especially on the expressive possibilities, or salience, of tools. This is interpreted as an emergent property of our engagement with tools, for which tools matter to us because (...) of what they show, not just because of what we do with them in a strict sense. A phenomenological approach is obtained by building upon Heidegger's view of tools as structured by implicit “indications” of relevance; this approach is developed by engaging with debates on mark making, stone tools, and aesthetic experience. It is argued that the salience of things is a process where indications of relevance become explicit and relatively distanced from motor affordances; this alliance of explicitness and absence of action allows for things to "resonate" in us, inviting us to see tools as invitations to imagine, think, and remember. The paper considers examples of entanglements of salience and affordances, where tools and techniques shape symbols and imaginaries. (shrink)

Plutarch’s account of Lucullus unsuccessfully begging his soldiers to follow him further, shortly before being forced to leave his command, is commonly read as the apex of his failure as a military leader. A close reading, however, reveals two hitherto overlooked aspects. Firstly, the story offers valuable information on late Republican military history, regarding the duration of military service before Augustus’ reform and the existence of clearly defined subgroups within the army. Secondly, the conflict between Lucullus and his soldiers allows (...) us to get a glimpse of the political debate of the time, characterised by the competing claims to Sulla’s heritage, the shift of military loyalty towards specific individuals, and above all the question of who really represented the interests of the res publica.
