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.

We first show that a theorem by Cartan that generalizes the Frobenius integrability theorem allows us (given certain conditions) to obtain noncurvature solutions for the differential Bianchi conditions and for higher-degree similar relations. We then prove that there is no algorithmic procedure to determine, for a reasonable restricted algebra of functions on spacetime, whether a given connection form satisfies the preceding conditions. A parallel result gives a version of Gödel's first incompleteness theorem within an (axiomatized) theory of gauge fields.

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

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

In this paper we examine some proposals to disprove the hypothesis that the interaction between mind and matter causes the collapse of the wave function, showing that such proposals are fundamentally flawed. We then describe a general experimental setup retaining the key features of the ones examined, and show that even a more general case is inadequate to disprove the mind-matter collapse hypothesis. Finally, we use our setup provided to argue that, under some reasonable assumptions about consciousness, such hypothesis is (...) unfalsifiable. (shrink)

O presente artigo pretende discorrer sobre o conceito de natureza possibilitado pela ontologia de Heidegger, que busca no pensamento grego seu sentido mais originário, e a crítica do filósofo ao conceito proporcionado pela metafísica clássica que teria provocado distopias na relação entre o homem e a natureza ao objetivá-la. Tal relação de domínio, além de evidenciar a necessidade de uma reflexão sobre o antropocentrismo, também e, por consequência disso, desvela-se através da crise ambiental vivida hoje por nós. Dessa forma, Heidegger (...) encontra tal sentido originário na palavra physis, o qual discuto nas páginas seguintes suas nuances a partir do que foi levantado pela obra do filósofo. Busca-se assim encontrar um sentido autêntico de natureza, antes do que foi assimilado pela tradição metafísica e desencoberto pelo ser humano como uma reserva ao seu dispor. (shrink)

Como é possível extrair filosofia de um texto de quatro ou cinco páginas, arbitrariamente montado ao longo de mil anos de citações na Antiguidade, cujo tamanho original se desconhece, e suas partes, precariamente conectadas, juntam-se a partir de critérios e suposições tardias? Normalmente, nem se quer refletimos sobre questões desse tipo quando tratamos de estudar o pensamento de um autor, pois é comum que o estudo de um filósofo não passe pela história da obra em questão, quando e de que (...) forma ocorreu a transmissão do texto ao longo da história. No presente artigo, teceremos algumas considerações importantes que leitor não familiarizado com o Poema de Parmênides tem de ter para que evite cair em armadilhas e reproduza dogmaticamente interpretações convencionalmente estabelecidas.

This paper is the result of reflections inspired by observing and participating in dancing sessions with children. Our experience of the latter led to the production of images that provoked a variety of questions, and invited us to think about the relationships between bodies, dance, and various forms of education. Among these questions were: what clues about the experience of human embodiment are given through observing children’s dance? What can children teach us through participating with them in this performative medium, (...) and what are its implications for education, most especially in light of our observations of children's inventiveness in this regard? Our impressions resonate and find expression in the oeuvre of Gilles Deleuze, Félix Guattari, Michel Foucault, Jan Masschelein and Manoel de Barros. Placing ourselves under their influence, we mobilized our thinking and opened ourselves to the emergent character of their ideas, resulting in what might be called a form of “dancing-writing” in which those two forms of expression interact. This dancing-writing is informed by and imbued with children’s lived experience: step by step, we walked the paths that they opened, recording as best we could their multisensorial approach to the world—gaze, taste, smell, sound, touch, movement. Ours was an experience of research on movement, with movement, in movement. As such, we harbor no intention to present final answers, but rather offer the reader an invitation to think philosophically and childishly. Ours is an invitation to dance with and among the questions which that very dance inspired. (shrink)

Para Kant, os jogos desempenham um papel extremamente importante na vida humana, já que são responsáveis por colocarem o espírito em atividade e, ao fazê-lo, avivá-lo na direção da sociabilidade, da moderação e do refinamento. De acordo com suas Lições de pedagogia e de antropologia, os jogos não são uma mera distração, eles são uma ótima ferramenta para se aprender a viver. O objetivo deste artigo é o de, em um primeiro momento, recuperar alguns dados biográficos de Kant para aclarar, (...) à luz dos jogos, a dinamicidade subjacente à austeridade do cumprimento da famosa rotina do filósofo alemão e, em seguida, explorar conceitualmente o destaque que Kant dá aos jogos no processo de moralização da criança e do adulto.

A intenção do artigo é examinar a reflexão de Algernon Sidney no que se refere ao direito de resistência do povo contra governos tirânicos. Amplamente discutido por autores das mais diversas vertentes políticas, o direito de resistência ocupou um lugar de destaque no debate jurídico, teológico e político no decorrer dos séculos XVI e XVII. Além dos tradicionais argumentos apresentados por huguenotes franceses, monarcômacos escoceses e defensores da causa parlamentar durante as guerras civis inglesas, a defesa de Sidney do direito (...) do povo de julgar, combater e depor tiranos é feita também com base em princípios republicanos, como o império da lei, o bem comum e, principalmente, a liberdade.

O presente artigo tem por objetivo apresentar a relação entre biopolítica e nazismo à luz da obra de Michel Foucault e Giorgio Agamben. Para Foucault, o nazismo utilizou-se do racismo de Estado para proteger uma raça e legitimar a morte daqueles que representavam uma espécie de perigo biológico. Seguindo a mesma via, Agamben nos convida a refletir sobre os campos de concentração não como um fato histórico superado, mas como uma estrutura de poder que vem sendo cada vez mais utilizada (...) nas democracias contemporâneas, marcada pela vigência do estado de exceção e produção da vida nua.Palavras-chave: Foucault.Agamben.Biopolítica. Campo. AbstractThis article aims to present the relationship between biopolitics and Nazism in the light of the work of Michel Foucault and Giorgio Agamben. According to Foucault, Nazism used state racism to protect a race and legitimize the death of those who represented a kind of biological danger. Following the same path, Agamben invites us to reflect on the concentration camps not as an outdated historical fact, but as a power structure which has been increasingly used in contemporary democracies, marked by the validity of the state of exception and production of bare life.Keywords: Foucault.

O filósofo alemão Hans Jonas dedica-se a questões que estão na agenda da discussão ética contemporânea. Sua teoria ético-metafísica, explicitada no livro O princípio responsabilidade: ensaio de uma ética para a civilização contemporânea retoma e amplia as indagações a respeito da relação existente entre homem e técnica na modernidade. O ponto de partida da sua tese é a afirmação de que as novas dimensões do agir humano - ocasionadas pela tecnologia - tornaram possível a realização de ações de grande impacto (...) tanto no globo terrestre quanto ao próprio homem. Questões como clonagem, manipulação genética, controle de comportamento, entre outras, mostram como a humanidade pode recriar um novo modelo humano. A partir destes pressupostos , este artigo concentra-se nas questões bioéticas mais especificamente no campo da medicina. Nossa pretensão é mostrar como Jonas propõe a aplicação de sua teoria moral na prática médica. (shrink)

A chegada e o estabelecimento da reflexão filosófica europeia no Brasil são indissociáveis do aristotelismo português trazido pelos jesuítas desde sua chegada ao então território colonial em 1549. A compreensão de determinados aspectos relacionados a este acontecimento não deve implicar na proposição de um fator determinista para a interpretação do modo como a filosofia é multiplamente tratada e pesquisada no país, mas certamente consiste em um fator imprescindível para a sua consideração. A argumentação a seguir visa indicar alguns aspectos ainda (...) presentes na forma segundo a qual a filosofia ainda é pensada entre nós. (shrink)

Philip Pettit sustenta que o neorrepublicanismo pode contribuir para o movimento feminista, visto que o seu princípio normativo central, o ideal de liberdade como ausência de dominação, pode ser amplamente utilizado na luta pela igualdade política, jurídica, social e cultural entre homens e mulheres. Com base em escritos de algumas autoras feministas, o artigo pretende discutir os limites da concepção neorrepublicana de liberdade, ao não considerar a dimensão social, cultural e estrutural da dominação masculina, para a causa feminista.

Quantum indistinguishability directly relates to the philosophical debate on the notions of identity and individuality. They are crucial for our understanding of multipartite quantum systems. Furthermore, the correct interpretation of this feature of quantum theory has implications that transcend fundamental science and philosophy, given that quantum indistinguishability is a resource in quantum information theory. Most of the conceptual analysis of quantum indistinguishability is restricted to studying the permutational invariance of quantum states, the concomitant quantum statistics and their entanglement. Here, we (...) analyse the role of indistinguishability and non-individuality in other areas of quantum theory. We start by analysing how a very peculiar use of indistinguishability underlies Feynman’s rules for summing amplitudes in interference phenomena. Next, we study how quantum indistinguishability is underestimated in several topics of debate in the quantum physics literature, such as the Einstein–Podolsky–Rosen argument, Bell’s inequalities and the Bell–Kochen–Specker theorem. Finally, we argue that an ontology of truly indistinguishable entities can serve as a basis for a quantum ontology that can give interesting answers to the interpretational problems of quantum mechanics. We claim that, in addition to superposition, contextuality and entanglement, indistinguishability (understood in a robust ontological sense) is one of the central features of quantum physics. -/- .

This edited volume examines aspects of the mind/consciousness that are relevant to the interpretations of quantum mechanics. In it, an international group of contributors focus on the possible connections between quantum mechanics and consciousness. They look at how consciousness can help us with quantum mechanics as well as how quantum mechanics can contribute to our understanding of consciousness. For example, what do different interpretations aimed at solving the measurement problem in quantum mechanics tell us about the nature of consciousness, such (...) as von Neumann's interpretation? Each interpretation has, associated to it, a corresponding metaphysical framework that helps us think about possible “models” of consciousness. Alternatively, what does the nature of consciousness tell us about the role of the observer and time reversibility in the measurement process? The book features 20 papers on contemporary approaches to quanta and mind. It brings together the work of scholars from different disciplines with diverse views on the connections between quanta and mind, ranging from those who are supportive of a link between consciousness and quantum physics to those who are very skeptical of such link. Coverage includes such topics as free will in a quantum world, contextuality and causality, mind and matter interaction, quantum panpsychism, the quantum and quantum-like brain, and the role of time in brain-mind dynamics.

The connection between quantum physics and the mind has been debated for almost a hundred years. There are several proposals as to how quantum effects might be relevant to understanding consciousness, including von Neumann’s Consciousness Causes Collapse interpretation (CCC), Penrose’s Orchestrated objective reduction (Orch OR), Atmanspacher quantum emergence theory, or Vitiello’s field theory. In this paper, we examine the CCC, in particular Stapp’s theory of interaction of mind and matter, and discuss how this imposes constraints to possible brain structures. We (...) then argue that those constraints may allow us to identify a possible locus of the interaction between mind and matter, if CCC is true. (shrink)
