I make a review on the aplications of the Bohm-de Broglie interpretation of quantum mechanics to quantum cosmology. In the framework of minisuperspaces models, I show how quantum cosmological effects in Bohm’s view can avoid the initial singularity, and isotropize the Universe. In the general case, I enumerate the possible structures of quantum space and time.

resumo: Este artigo é uma introdução geral ao pensamento de Bernard Stiegler em torno da relação entre técnica e humano. Stiegler desconstroi a tradição filosófica que costumava separar technê e episteme com um enfoque histórico e materialista, a fim de provar como é impossível pensar a humanidade sem a técnica. Portanto, a relação não é de oposição, como a tradicional metafísica do espírito defende, mas composição, do modo como defendem Gilbert Simondon, Jacques Derrida, Andre Leroi-Gourhan e Gilles Deleuze. abstract: This (...) paper is a general introduction to Bernard Stiegler's thinking about the relation between technique and human. Stiegler deconstructs the philosophical tradition that used to separate teckhnê and episteme with a historical and materialist approach in order to prove how it is impossible to think humanity without technique. Therefore, the relation is not one of opposition, like the traditional metaphysics of spirit defends, but one of composition, as thinkers like Gilbert Simondon, Jacques Derrida, Andre Leroi-Gourhan and Gilles Deleuze defend.

O texto investiga os “indesconstruíveis” na filosofia de Jacques Derrida e sua relação com espectrologia, fé e messianidade. Partindo de uma imagem de ziguezague, ela própria presente em diversos ensaios derridianos, aproxima e desaproxima os indesconstruíveis (justiça, perdão, promessa, dom etc.) das ideias de indecidível e decisão, místico e espectral e, finalmente, imanente e transcendente. A partir do debate sobre a Era Axial, pergunta-se, então, se os indesconstruíveis derridianos podem mesmo postular a universalidade, apresentando como contraponto o tratamento da fé (...) secular em Hägglund e da espectralidade nas metafísicas ameríndias tal como descritas por Eduardo Viveiros de Castro.

This essay seeks a new approach between philosophy and neuroscience inspired by the recent ontological turn to think about one of the affects modulations across the contemporary sociopolitical scenario. In this regard, it theoretically triangulates the appropriation of Spinoza's philosophy by neuroscientist Antonio Damasio and the reception of Damasio's neuroscience by philosopher Catherine Malabou, taking Gilles Deleuze as a connecting point between these perspectives. It proposes to think the concept of destructive plasticity as a metamorphosis in the organism that, shocked (...) by some traumatic event, turns to a new configuration that deactivates its somatic markers and ends up taking a form of disaffection. Finally, it concludes by bringing this figure closer to what Achille Mbembe, taking the death drive as central concept for thinking necropolitics, names as "lumpenradical". (shrink)

In this paper we study in details a system of two weakly coupled harmonic oscillators from the point of view of Bohm's interpretation of quantum mechanics. This system may be viewed as a simple model for the interaction between a photon and a photodetector. We obtain exact solutions for the general case. We then compute approximate solutions for the case where one oscillator is initially in its first excited state (a single photon) reaching the other oscillator in its ground state (...) (the photodetector). The approximate solutions represent the state of both oscillators after the interaction, which is not an eigenstate of the individual hamiltonians for each oscillator, and therefore the energies for each oscillator do not exist in the Copenhagen interpretation of Quantum Mechanics. We use the approximate solutions that we obtained to compute Bohmian trajectories and to study the energy transfer between the oscillators. We conclude that, even using the Bohmian view, the energy of each individual oscillator is not well defined, as the nonlocal quantum potential is not negligible even after the coupling is turned off.

O presente estudo consiste em uma análise do processo de composição do Timeu-Crítias de Platão, sob o ponto de vista da modelagem do discurso. Pretende-se mostrar que o diálogo é marcado por uma engenhosa articulação de técnicas de composição, que combinam os aspectos pictorial e dramático da mímesis poética. Estabelecendo as Panateneias como referência implícita, a obra apresenta a performance de uma sequência de narrativas, produzidas como verdadeiras imagens discursivas. A originalidade platônica revela-se no Timeu-Crítias, portanto, no desempenho de uma (...) construção formal ao mesmo tempo dramática e imagética, mediante um singular agenciamento mimético de formas do discurso.

In this paper I try to exhibit Law’s hidden matrix: the state of exception in which we live – and the correspondent bare life – discussing relations between Law and power. To prove it, I aim to show how the liberal tradition – matrix of the recent constitutional theory – hides this phenomenon, being incapable to explain how exactly those who feels more deeply the violence of State – poor people, immigrants, etc. – are evidently out of the supposed contract.

O artigo pretende apresentar a neurofilosofia de Catherine Malabou em alguns dos seus principais eixos. Para tanto, após dividir a obra da filósofa em quatro segmentos, dirige-se aos estudos sobre o cérebro que investigam as questões epistemológicas e políticas que as neurociências colocam para as humanidades. A investigação se dá em três momentos: a) Que fazer do nosso cérebro?, que propõe superar o dualismo como modelo da resistência às neurociências e incorporar a biologia no altermundismo; b) os textos que criticam (...) a noção atual de biopolítica como chave para exclusão da problemática neuronal e biológica das principais questões ético-políticas do nosso tempo; e, finalmente c) a questão da inteligência artificial e como o problema do cérebro colabora para a construção de um novo paradigma na educação e na política a partir da relação com o cérebro azul artificial. Finalmente, conclui propondo uma internalização da problemática neurofilosófica como superação do gap natureza/simbólico que mantém as humanidades presas a uma ideia de transcendência. (shrink)

O texto busca explorar a relação entre Da Gramatologia, de Jacques Derrida, e a ciência da sua época. Ele parte de três importantes obras lidas e citadas por Derrida como fontes da sua pesquisa em torno à escritura, Madeleine V-David, André Leroi-Gourhan e a compilação de um Colloque, para explicar o papel da escritura em si mesma no pensamento de Derrida enquanto um sinal do seu materialismo. Paratanto, em contraste com o uso ordinário do termo “escritura”, busca compreendê-la metonimicamente como (...) inscrição sulcada no real, buscando a partir do debate interdisciplinar de Derrida entender as múltiplas dimensões pelas quais o problema foi pensado.

The present study is an analysis of Plato’s _Timaeus-Critias_ composition process, from the point of view of discourse modeling. It intends to show that the dialogue is distinguished by an insightful articulation of composition techniques, which combine the pictorial and dramatic aspects of poetic _mimesis_. Establishing the Panateneias as an implicit reference, the work presents the performance of a sequence of narratives, produced as true discursive images. Platonic originality is revealed in _Timaeus-Critias_, therefore, as the accomplishment of a formal construction (...) that is both dramatic and representational, through a singular mimetic agency of discursive forms.

Embasados nas concepções de forma arquitetônica de Bakhtin, procuramos demonstrar como as dimensões dos enunciados praticados nos ambientes virtuais de aprendizagem (AVA) estão diretamente ligadas ao design (concepção, idealização e forma), ou seja, à forma arquitetônica de realização, defendido como o design de um AVA, que pode propiciar (novos) multiletramentos, flexibilizar ou não, em sua forma de realização, gêneros multissemióticos advindos do mundo contemporâneo. Para tanto, observamos o design de duas ferramentas em dois AVA distintos e concluímos que, no primeiro, (...) o ambiente digital está baseado nas relações de tempo e espaço (e poder) da escola tradicional, gerando uma forma arquitetônica de realização de uma escola marcada pelos gêneros e letramentos escolares convencionais. No segundo, ao observarmos o todo arquitetônico, concluímos que o seu design propicia o uso de diferentes modos de linguagem - textual, gráfica, sonora, com imagens estáticas e dinâmicas, com fácil comunicação/interação com os meios tecnológicos da contemporaneidade.

Partimos da afirmação de K.-O. Apel, repetida por João Maria André, de que "[...] é na ‘mística' do ‘logos' e na teologia negativa do Pseudo-Dionísio que, de modo determinante, Nicolau de Cusa irá beber os traços fundamentais da sua filosofia da linguagem". Com base no De filiatione Dei propomo-nos refletir sobre a relação fundamental e constitutiva entre o verbo mental humano e o Verbo ou Logos eterno. A importância desse texto, no âmbito do problema da linguagem em Nicolau de Cusa, (...) é reconhecida por Casarella justamente por sua inflexão cristológica em relação aos primeiros sermões, pois, em oposição à reflexão intratrinitária dos sermões, a imagem humanamente visível de Cristo torna-se o espelho da linguagem, ou seja, em Cristo, vemos de modo perfeito o que pode ser expresso por meio da linguagem. O texto cusano é uma meditação sobre Jo, I, 12: "Mas a todos que o receberam deu o poder de se tornarem filhos de Deus: aos que creem em seu nome". Interessa-nos principalmente a meditação sobre os exemplos aduzidos por Nicolau de Cusa para explicitar de que modo colhemos a unidade divina intelectualmente, pois serão nesses exemplos ou enigmas que o autor pensará a relação constitutiva entre o verbo mental humano e o verbo mental inefável. We begin with the statement of K.-O. Apel, repeated by João Maria André, that "[…] it is in the ‘mystic' of the ‘logos' and in the negative theology of pseudo-Dionysus that, in a determinate manner, Cusa would receive the fundamental features of his philosophy of language". Based on De filiatione Dei, we reflect on the fundamental and constitutive relationship between the mental human word and the eternal Word or Logos. The importance of this text in the context of the problem of language in Cusa is recognized by Casarella, specifically for its Christological inflection in relation to Cusa's first sermons. In opposition to the intra-Trinitarian reflection of the sermons, in De filiatione Dei the humanly visible image of Christ becomes the mirror of language; that is, it is in Christ that we see the perfect mode that can be expressed by means of language. Cusa's text is a meditation on John 1:12: "But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name". Of principal interest to us are the examples adduced by Cusa that make explicit the way in which we intellectually receive the divine unity, as it is in these examples or enigmas that the author reflects on the constitutive relation between the mental human word and the ineffable mental word.

"The Concept of Number", by Ernst Cassirer, is the second chapter of his first systematic work, the "Substanzbegriff und Funktionsbegriff: Untersuchungen über die Grundfragen der Erkenntniskritik", originally published in German in 1910. The translation to English, in 1953, by Marie Collins Swabeyand William Curtis Swabey, under the title "Substance and Function and Einstein's Theory of Relativity", despite its importance for having widely disseminated the work, loses in its title the work's essence: the opposition between "concept-substance" and "concept-function", or rather, between (...) "substantial-concept" and "functional-concept". Cassirer possesses along with a "theory of symbolical forms" a "theory of culture". These theories are "theories of conceptual formation" and they are in charge of various case studies developed by Cassirer in “Substanzbegriff und Funktionsbegriff”. Chapter 2, now translated, is a reading of the historical development of the concept of number under the view of a general theory of the concept that he presents in the second chapter of the book “Zur Theorie der Begriffsbildung” (On the theory of the conceptual formation).

We study the SIS and SIRI epidemic models discussing different approaches to compute the thresholds that determine the appearance of an epidemic disease. The stochastic SIS model is a well known mathematical model, studied in several contexts. Here, we present recursively derivations of the dynamic equations for all the moments and we derive the stationary states of the state variables using the moment closure method. We observe that the steady states give a good approximation of the quasi-stationary states of the (...) SIS model. We present the relation between the SIS stochastic model and the contact process introducing creation and annihilation operators. For the spatial stochastic epidemic reinfection model SIRI, where susceptibles S can become infected I, then recover and remain only partial immune against reinfection R, we present the phase transition lines using the mean field and the pair approximation for the moments. We use a scaling argument that allow us to determine analytically an explicit formula for the phase transition lines in pair approximation. (shrink)

O presente artigo trata da relação entre teoria e prática no pensamento de Theodor W. Adorno com o objetivo de analisar as possibilidades de emancipação do sujeito no âmbito da sociedade capitalista contemporânea, questionando sobre um suposto pessimismo do autor. Para tanto, serão contextualizadas as relações entre sujeito e objeto, natureza e razão, teoria e prática e formação e semiformação, com a finalidade de pensar a importância fundamental da teoria para a transformação do mundo a partir de uma análise crítica (...) da sociedade, bem como a pertinência dessa análise ao atual momento brasileiro. A transformação do mundo será pensada a partir das possibilidades de emancipação do sujeito e o papel da formação humana nesse processo no interior de um modelo educacional cada vez mais determinados pelos interesses do capital que direcionam a educação a aspectos meramente práticos de adaptação ao mercado de trabalho. A conclusão aponta no sentido da necessidade imperativa da manutenção da formação teórica e crítica diante dos constrangimentos de ordem prática de um mundo administrado pelos valores capitalistas.

Critical Theory and Educational Practice: On the relationship between theoretical pessimism and the transformation of the world to T.W. Adorno Abstract: This article deals with the relationship between theory and practice in the thought of Theodor W. Adorno with the aim of analyzing the possibilities of the subject's emancipation in the context of contemporary capitalist society, questioning the author's supposed pessimism. Therefore, the relationships between subject and object, nature and reason, theory and practice, and Bildung and Halbbildung will be contextualized, with the purpose of thinking about the fundamental importance of theory for the transformation of the world from a thought marked by a critical analysis of the society, as well as the relevance of this analysis to the current Brazilian moment. The transformation of the world will be thought from the possibilities of emancipation of the subject and the role of human formation in this process within an educational model increasingly determined by the interests of capital that led education to merely practical aspects of adaptation to the labor market. The conclusion points towards the imperative need to maintain theoretical and critical education in the face of practical constraints in a world managed by capitalist values. Key-words: Theodor W.

RESUMO O presente artigo pretende explorar um tema ainda incipiente na literatura secundária referente ao estatuto do direito em Giorgio Agamben e ao peso do direito romano em seus trabalhos. Para isso lançamos mão do debate entre Agamben e Yan Thomas, um importante historiador do direito romano com quem Agamben teve um contato bastante intenso. Ao longo do artigo pretenderemos mostrar três coisas: em primeiro lugar, a relação de Agamben com a biopolítica, destacando, sobretudo, o aspecto articulatório da noção de (...) dispositivo que subjaz suas investigações. Em segundo lugar, a importância do ensaio Vita necisque potestas de Yan Thomas, que servirá para Agamben introduzir diferenças em relação a Hannah Arendt e Michel Foucault. Por fim, lançaremos luz sobre o estatuto do direito no pensamento de Agamben, que, é a nossa hipótese, comunga da visão thomasiana: o direito não seria uma realidade metafísica ou substancial, mas funcionaria por meio de artifícios e ficções, o que nos permite pensar o direito enquanto um autêntico dispositivo biopolítico. ABSTRACT This article intends to explore a still incipient theme in the secondary literature regarding the status of the law in Giorgio Agamben and the weight of Roman law in his works. To this end, we have used the debate between Agamben and Yan Thomas, an important historian of Roman law with whom Agamben had a very intense contact. Throughout the article we will show three things: firstly, the relationship between Agamben and biopolitics, emphasising the articulatory aspect of the notion of apparatus which underlies his investigations. Then we will point out the importance of the essay Vita necisque potestas by Yan Thomas, which will serve for Agamben to introduce differences in relation to Hannah Arendt and Michel Foucault. Finally, we will shed light on the statute of law in Agamben’s thought, which is our hypothesis, communes with the Thomasian view: law would not be a metaphysical or substantial reality, but would work through artifice and fiction, which enables us to think the law as an authentic biopolitical apparatus.

After the publication of Hart's Concept of Law, Dworkin published his article “The Model of Rules,” dividing positivism into two varieties: inclusive and exclusive. Many theorists involved in this debate have characterized Hart's position as inclusivist, which we reject in this article. We argue that Hart, in the postscript to The Concept of Law, conceded a point to Dworkin in accepting that inclusive positivism would imply the existence of objective moral standing, adopting a more “neutral” position—compatible with inclusive and exclusive (...) positivism—and consequently distancing himself from the incorporation thesis, which is paramount to inclusive positivism.

The shooting bias hypothesis aims to explain the disproportionate number of minorities killed by police. We present the evidence mounting in support of the existence of shooting bias and then focus on two dissenting studies. We examine these studies in light of Biddle and Leuschner’s “inductive risk account of epistemically detrimental dissent” and conclude that, although they meet this account only partially, the studies are in fact epistemically and socially detrimental as they contribute to racism in society and to a (...) social atmosphere that is hostile to science as scholars working on issues of racism come under attack. We emphasize this final point via recourse to Kitcher’s “Millian argument against the freedom of research.”. (shrink)

Two papers by Nelson Goodman are included in (...) the collection and there are analyses of his work by seven leading academics in anthropology, philosophy, sociology and musicology. (shrink)

Resumo: Este artigo possui o propósito de colocar à prova a interpretação heideggeriana acerca das noções nietzschianas de vontade de potência e eterno retorno do mesmo. Para levar a cabo o referido objetivo, de início, apresentaremos o argumento desenvolvido por Heidegger nas suas preleções e textos sobre Nietzsche, editadas e publicadas em dois volumes, no ano de 1961. Num segundo momento, examinaremos, em Nietzsche: sua filosofia dos antagonismos e os antagonismos de sua filosofia, a resposta que Müller-Lauter ofereceu à crítica (...) de Heidegger. Por ocasião deste exame, tentaremos salientar que haveria certa insuficiência na réplica deste comentador. Por fim, iremos recorrer aos textos do próprio Nietzsche para tentar promover uma confrontação com a interpretação do Filósofo da Floresta Negra.: This article has the purpose to challenge the Heideggerian interpretation of Nietzsche’s notions of will to power and eternal recurrence. To carry out this objective, we will first present the argument developed by Heidegger in his lectures and texts on Nietzsche, edited and published in two volumes, in 1961. In a second moment, we will examine, in Nietzsche: his philosophy of antagonisms and the antagonisms of his philosophy, the answer that Müller-Lauter offered to Heidegger’s criticism. On the occasion of this examination, we will try to point out that there would be a certain insufficiency in this commenter’s reply. Finally, we will resort to Nietzsche’s own texts to try to promote a confrontation with the Black Forest Philosopher’s interpretation. (shrink)

The article examines the process of niche standardization in medical research as an example of democratizing strategies implemented in industry-funded science. I argue that niche standardization can lead to undesirable epistemic and ethical consequences, if the various goals of research are not properly aligned. I examine two examples: the case of Sarafem, approved for the treatment of premenstrual dysphoric disorder in women, and the case of BiDil, approved for exclusive use in African Americans for the treatment of congestive heart failure. (...) I conclude by cautioning against the unqualified support of democratizing strategies in industry-funded research. (shrink)

This article adapts the ethnographic medium of the diary to develop a method for studying data and related data practices. The article focuses on the creation of one data diary, developed iteratively over three years in the context of a national centre for monitoring disasters and natural hazards in Brazil. We describe four points of focus involved in the creation of a data diary – spaces, interfaces, types and situations – before reflecting on the value of this method. We suggest (...) data diaries are able to capture the informal dimension of data-intensive organisations; enable empirical analysis of the specific ways that data intervene in the unfolding of situations; and as a document, data diaries can foster interdisciplinary and inter-expert dialogue by bridging different ways of knowing data.

Dionysus has several sets throughout Friedrich Nietzsche (1844-1900) books. This question will arouse the interest of Brazilian interpreters when football is under observation. The aim of this article is to discuss the appropriations from the philosopher's concepts since the first half of the twentieth century. Commentators and the author himself saw that there are inflections about this theme in the Nietzschean work. The wide circulation of football elements in Brazil, its close connection with the national identity and with the popular (...) cultural has to be taken into account in a consistent investigation.

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits (...) will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

Diese Schriften kennzeichnen den Weg, auf dem Nelson - Kant folgend - sein Ziel einer "kritischen Philosophie" angestrebt hat. Es geht ihm darum, durch Kritik der Vernunft unmittelbare Erkenntnisse aus reiner Vernunft aufzusuchen, ihnen die Maßstäbe für wissenschaftliches Philosophieren zu entnehmen und so, im Selbstvertrauen der Vernunft, Ausblicke auf pädagogische Aufgaben und Weltanschauungsfragen zu gewinnen.

The growing body of research on interdisciplinarity has encouraged a more in depth analysis of the relations that hold among academic disciplines. In particular, the incursion of one scientific discipline into another discipline’s traditional domain, also known as scientific imperialism, has been a matter of increasing debate. Following this trend, Scientific Imperialism aims to bring together philosophers of science and historians of science interested in the topic of scientific imperialism and, in particular, interested in the conceptual clarification, empirical identification, and (...) normative assessment of the idea of scientific imperialism. Thus, this innovative volume has two main goals. Indeed, the authors first seek to understand interdisciplinary relations emerging from the incursion of one scientific discipline into one or more other disciplines, such as in cases in which the conventions and procedures of one discipline or field are imposed on other fields; or more weakly when a scientific discipline seeks to explain phenomena that are traditionally considered proper of another discipline’s domain. Secondly, the authors explore ways of distinguishing imperialistic from non-imperialistic interactions between disciplines and research fields. (shrink)

Este ensaio introdutório faz uma breve apresentação do tratado de óptica atribuído a Euclides de Alexandria, inserindo-o no contexto das teorias sobre a visão formuladas pelas doutrinas filosóficas antigas. Ressalta-se o antagonismo entre a análise geométrica da visão, empreendida por Euclides, e as considerações filosóficas acerca dos processos físicos subjacentes à sensação visual. Pretende-se mostrar que o objeto da óptica euclidiana é a percepção visual daquilo que Aristóteles denomina "sensível comum". This introductory essay provides an abridged presentation of the optical (...) treatise attributed to Euclid of Alexandria, placing it in the context of theories about vision formulated by the ancient philosophical doctrines. I emphasize the antagonism between the geometric analysis of vision, undertaken by Euclid, and the philosophical considerations about the physical processes underlying visual sensation. In addition, I aim to show that the object of Euclidean optics is the visual perception of what Aristotle calls "common sensible". (shrink)
