This paper establishes model-theoretic properties of \, a variation of monadic first-order logic that features the generalised quantifier \. We will also prove analogous versions of these results in the simpler setting of monadic first-order logic with and without equality and \, respectively). For each logic \ we will show the following. We provide syntactically defined fragments of \ characterising four different semantic properties of \-sentences: being monotone and continuous in a given set of monadic predicates; having truth preserved under (...) taking submodels or being truth invariant under taking quotients. In each case, we produce an effectively defined map that translates an arbitrary sentence \ to a sentence \ belonging to the corresponding syntactic fragment, with the property that \ is equivalent to \ precisely when it has the associated semantic property. As a corollary of our developments, we obtain that the four semantic properties above are decidable for \-sentences. (shrink)

Artificial intelligence has been adopted in a wide range of domains. This shows the imperative need to contribute to making citizens insightful actors in debates and decisions involving the adoption of AI mechanisms. Currently, existing approaches to the teaching of basic AI concepts through programming treat machine intelligence as an external element/module. After being trained, that external module is coupled to the main application. Combining block-based programming and WiSARD weightless artificial neural networks, this article presents the conceptualization and design of (...) a new methodology, AI from concrete to abstract, to endow general people with a minimum understanding of what AI means. The main strategy adopted was to include AI training and classification primitives as blocks that compose an otherwise conventional computer program. This way, the programmer can use these blocks as he/she uses other programming constructs. In order to achieve this purpose, we also propose BlockWiSARD, a block-based programming environment designed to promote the demystification of artificial intelligence via practical activities related to the development of learning machines, as well as through the observation of their learning process. As a beneficial side effect of BlockWiSARD, the difference between a program capable of learning from data and a conventional computer program becomes more evident. In addition, the simplicity of the WiSARD weightless artificial neural network model enables easy visualization and understanding of training and classification tasks internal realization. (shrink)

The title, “a reflection on the foundations of probability and statistics”, calls back to Teddy’s seminal book, “Rethinking the Foundations of Probability and Statistics”, bookends to a career that has made fundamental contributions to (...) the foundations of probability and statistics, and shaped the field of imprecise probability. It is aimed at scholars engaged in probability and statistics. (shrink)

In this sixth issue of Speculations, a serial imprint created to explore post-continental philosophy and speculative realism, a wide range of contemporary philosophical issues pertaining to the contemporary philosophical scene is touched upon, from the continental realism of Tristan Garcia, Graham Harman and Quentin Meillassoux to the 'new realism' of Maurizio Ferraris, from Lacanian and Laurellian speculations to the synthetic philosophy of Fernando Zalamea's mathematics.

Synapsins I and II are a family of synaptic vesicle‐associated phosphoproteins involved in the short‐term regulation of neurotransmitter release. In this review, we discuss a working model for the molecular mechanisms by which the synapsins act. We propose that synapsin I links synaptic vesicles to actin filaments in the presynaptic nerve terminal and that these interactions are modulated by the reversible phosphorylation of synapsin I through various signal transduction pathways. The high degree of homology between the synapsins suggests that some (...) of the functional properties of synapsin I are also shared by synapsin II. (shrink)

Apresentação do dossiê comemorativo do centenário de publicação do livro _Duração e simultaneidade_, de Henri Bergson.

Review of the book Um obscuro encanto: gnose, gnosticismo e poesia moderna , writen by Cláudio Willer. São Paulo, Editora Civilização Brasileira, 2010.

O objetivo do artigo é compreender como as metamorfoses econômicas e sociais vivenciadas e experienciadas nas comunidades quilombolas do território Terra da Liberdade, situadas no Baixo Tocantins, estado do Pará, produzem dizeres e linguagem, e, assim, formas de uma comunicação de resistência. Parte-se da reflexão de Heidegger (2001) sobre a relação entre existência e lugar para compreender o processo de construção dialogada do Protocolo de Consultas do território. A metodologia utilizada foi a observação participante com entrevistas abertas e semiestruturadas, num (...) diálogo entre etnografia e fenomenologia. Observamos que o direito de "se dizer" é um conjunto de lutas comunicacionais. Compreendendo comunicação como dizer coletivo e social, o artigo reflete sobre lutas por reconhecimento da identidade, dos direitos, do território. (shrink)

Uma das questões mais interessantes do debate contemporâneo sobre a justiça, no âmbito da teoria política normativa, diz respeito sobre qual foco deveria ocupar a posição central de uma visão igualitarista: igualdade baseada em satisfação de necessidades básicas, bens primários como propõe Rawls, igualdade de recursos como defende Dworkin ou, como quer Amartya Sen, igualdade de capacidades? Com o que, afinal, os igualitaristas deveriam se preocupar? Este trabalho tem o objetivo de analisar criticamente essas três perspectivas.

A covid-19 tem gerado grande mobilização por parte das sociedades contemporâneas. Como forma de prevenção e controle da doença, o isolamento social tem sido uma medida eficaz, recomendada por diversos órgãos da saúde. Por isso, pensar o isolamento social como prática solidária tem sido fundamental. Nesta perspectiva, o presente artigo busca problematizar o isolamento social enquanto isolamento solidário. Para isso, partimos da tematização da enfermidade, até agora conhecida, seus modos de prevenção e controle e, por conseguinte, o diálogo entre a (...) Saúde Coletiva e a Hermenêutica Filosófica, na tentativa de repensar o isolamento criticamente, para além de uma questão biomédica. Assim, discutir o isolamento solidário como noção essencial ao enfrentamento da pandemia da COVID-19 significa contribuir para uma visão mais ampla de saúde, ao passo que se encontra em jogo o restabelecimento da vida comunitária para além de sua concepção biomédica.

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”.

This work evaluated the structure of dreams in people affected by schizophrenia. The verbal reports of 123 schizophrenic patients were compared with 123 dream reports from a control group. In accordance with the Jungian conceptualization of, dreams as texts, dream reports were assessed using textual analysis processing techniques.Significant differences were found in textual parameters, showing that the dreams reports of schizophrenic patients differ from those of the control group. It is thus possible that schizophrenia probably underlies changes in the oneiric (...) production and dream reports. This work confirms the value of textual analysis in the study of oneiric material.

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.

We present a new puzzle about logical truth, necessity, and moral responsibility. We defend one solution to the puzzle. A corollary of our preferred solution is that prominent arguments for the incompatibility of determinism and moral responsibility are invalid.

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..

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)

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.

Popular sovereignty requires that citizens perceive themselves as being able to act and implement decisions, and that they are de facto causally connected to mechanisms of decision making. I argue that the two most common understandings of the exercise of popular sovereignty—which center on direct decision making by the people as a whole and the indirect exercise of democratic agency by elected representatives, respectively—are inadequate in this respect, and go on to suggest a complementary account that stresses the central role (...) of internally democratic and participatory political parties in actualising popular sovereignty, drawing on the democratic theory of Hans Kelsen.

David Chalmers argued against the claim that for all p, or even for all entertainable p, it is knowable a priori that p iff actually p. Instead of criticizing Chalmers’s argument, I suggest that it can be generalized, in a sense, and in interesting ways, concerning other principles about contingent a priori truths. In particular, I will argue that the puzzle presented by Chalmers runs parallel to others that do not turn on ‘actually’. Furthermore, stronger arguments can be presented that (...) do not turn on apriority either, though they do entail the conclusion of Chalmers’s argument. All such puzzles involve interactions between rigidifying sentence-forming devices with factive operators. (shrink)

Implicações da noção de consciência histórica nas ciências humanas e sociais: um modo de projeção para o futuro e de posição em relação ao passado Resumo: O presente texto, de caráter bibliográfico, discute o problema da consciência histórica com o objetivo de pensar o sentido dessa expressão na atualidade e as variações que esse conceito adquiriu ao longo da história das Ciências Humanas e Sociais, com ênfase no século XX. A hipótese é que a discussão a respeito da consciência histórica (...) passou a se ocupar, na modernidade, com uma múltipla relatividade de pontos de vista, o que é destacado por Gadamer em sua análise sobre os preceitos implicados na definição do que significa “ter senso histórico”. É defendida a tese, portanto, de que a noção de consciência histórica não se limita ao conhecimento das experiências vivenciadas no passado, mas se apresenta como condição de possibilidade de projetar o futuro e se posicionar em relação ao passado, especialmente no que diz respeito às ciências humanas e sociais. A defesa desta ideia central é realizada por meio de dois gestos reflexivos, com apresentação, primeiramente, do marco teórico da consciência histórica e, posteriormente, de suas implicações na constituição das Ciências Humanas e Sociais. Palavras-chave: Ciências humanas e sociais. Senso histórico. Passado. Futuro. Implications of the notion of historical consciousness in human and social sciences: a mode of projection for the future and position in relation to the past: This bibliographic text discusses the problem of historical consciousness with the purpose of thinking about the meaning of this expression in the present time and the variations that this concept has acquired throughout the history of the Humanities and Social Sciences, with emphasis on the twentieth century. The hypothesis is that the discussion about historical consciousness has come to concern itself, in modernity, with a multiple relativity of points of view, which is highlighted by Gadamer in his analysis of the precepts involved in defining what “having a historical sense” means. Therefore, the thesis that the notion of historical consciousness is not limited to the knowledge of past experiences is defended, but is presented as a condition of possibility of projecting the future and positioning itself in relation to the past, especially with regard to humanities and social sciences. The defense of this central idea is made through two reflexive gestures, presenting, first, the theoretical framework of historical consciousness and, later, its implications in the constitution of the Human and Social Sciences. Keywords: Human and social sciences. Historical sense. Past. Future.

A tradição mágica helênica tem no (...) phármakon seu elemento de continuidade nos períodos arcaico e clássico. (shrink)

Luigi Sacco (1769–1863) was the main protagonist of early vaccination campaign in Italy. He found a native source of vaccine lymph: with that, he personally vaccinated more than 500,000 people and furnished all Italy and some Middle East countries too. Starting from the pictures of his books, Sacco proposed to create wax models of real and spurious smallpox pustules in human, cow, sheep and horse; just to permit, not only to doctors, but also to all other health operators, the identification (...) of the right pustules from where to extract active lymph for vaccination. In the Museum of Pathological Anatomy of the Padua University Medical School, we have four anatomical waxes which corresponded exactly to the explicative pictures in 1809 Sacco’s treatise on Vaccine. We have found the same models also at the University of Milan, Pavia and Bologna—the main cities of Cisalpine Republic , the state of North Italy formed at the epoch of Sacco following the Napoleon conquest. The history of the diffusion of these models presented in this text will be a starting point to develop wider questions. In particular, this history could be useful to improve our understanding of the birth of scientific and experimental medicine through XIX and XX Century. (shrink)

The paper provides a qualified defence of Bruce Waller’s deductivist schema for a priori analogical arguments in ethics and law. One crucial qualification is that the schema represents analogical arguments as complexes composed of one deductive inference but also of one non-deductive subargument. Another important qualification is that the schema is informed by normative assumptions regarding the conditions that an analogical argument must satisfy in order for it to count as an optimal instance of its kind. Waller’s schema is defended (...) from criticisms formulated by Trudy Govier, Marcello Guarini and Lilian Bermejo-Luque. (shrink)

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.

Brazil stands out at the global level for having implemented several policies intending to promote agroecology as a productive paradigm for small-holder farmers. However, the impacts of this process of institutionalization of agroecology still lack research and debates that evaluate the effectiveness of these policies. In this paper, we assess and discuss the impacts of a policy specifically focused on education in agroecology, the support to the establishment of Centers for the Study of Agroecology and Organic Production (NEAs) in more (...) than 150 higher education institutions throughout Brazil. NEAs bring together teachers, researchers, and students who engage in teaching, research, and extension activities in partnerships with peasant farmers, their organizations, and rural extension workers. The hypothesis that guides our analysis is that this support to establish NEAs allowed redistribution of symbolic power in the universities where they were established, supporting agroecology to gain greater legitimacy inside and outside the university field. Based on an in-depth study of four NEAs, performed through participant observation and documentary analysis, the NEAs are evaluated from the perspective of social fields in dispute, first in a university sphere, but also from the perspective of training people in integrative and transdisciplinary thinking that will contest the industrial-corporate food regime. Our findings suggest that the State support to university groups dedicated to the promotion of agroecology has allowed the construction of what we have named agroecological spaces, which symbolically dispute the dominant paradigms in educational institutions, supporting the constitution of material and immaterial agroecological territories.
