It has been shown that the orbits of motion for a wide class of non-relativistic Hamiltonian systems can be described as geodesic flows on a manifold and an associated dual by means of a conformal map. This method can be applied to a four dimensional manifold of orbits in spacetime associated with a relativistic system. We show that a relativistic Hamiltonian which generates Einstein geodesics, with the addition of a world scalar field, can be put into correspondence in this way (...) with another Hamiltonian with conformally modified metric. Such a construction could account for part of the requirements of Bekenstein for achieving the MOND theory of Milgrom in the post-Newtonian limit. The constraints on the MOND theory imposed by the galactic rotation curves, through this correspondence, would then imply constraints on the structure of the world scalar field. We then use the fact that a Hamiltonian with vector gauge fields results, through such a conformal map, in a Kaluza-Klein type theory, and indicate how the TeVeS structure of Bekenstein and Saunders can be put into this framework. We exhibit a class of infinitesimal gauge transformations on the gauge fields ${\mathcal{U}}_{\mu}(x)$ which preserve the Bekenstein-Sanders condition ${\mathcal{U}}_{\mu}{\mathcal{U}}^{\mu}=-1$ . The underlying quantum structure giving rise to these gauge fields is a Hilbert bundle, and the gauge transformations induce a non-commutative behavior to the fields, i.e. they become of Yang-Mills type. Working in the infinitesimal gauge neighborhood of the initial Abelian theory we show that in the Abelian limit the Yang-Mills field equations provide residual nonlinear terms which may avoid the caustic singularity found by Contaldi et al.

René Descartes (1596-1650)?: un classique de la philosophie, père du rationalisme, disciple du dualisme platonicien et inventeur du cogito. 0Il existe pourtant un autre Descartes, méconnu?: l’observateur de ce qui, en l’homme, se situe à la limite du rationnel et de l’irrationnel. Bref, en cette partie qu’est, aux confins de l’âme et du corps, le non-rationnel?: la sensibilité ou, mieux, l’affectivité. D’où le sens du titre de ce livre?: le clair-obscur de la conscience, réunissant les idées claires et distinctes de (...) l’âme et les idées obscures et confuses du corps. 0C’est donc, chronologiquement, le troisième et dernier Descartes, le moins étudié mais le plus authentique, que l’on analysera ici?: après le savant du Discours de la Méthode, puis le métaphysicien des Méditations, le psychologue des Passions de l’âme. Ainsi est-ce un Descartes original et inédit, réévalué et actualisé à la lumière de la philosophie contemporaine, que le lecteur découvrira en ces pages. (shrink)

Do all questions have answers? How much can we know about the world? Is there such a thing as an ultimate truth? To be human is to want to know, to understand our origins and the meaning of our lives. In The Island of Knowledge, physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence, the origin of the universe, the nature of reality, and the limits of knowledge. In so doing, he reaches a (...) provocative conclusion: science, the main tool we use to find answers, is fundamentally limited. As science and its philosophical interpretations advance, we are often faced with the unsettling recognition of how much we don't know. Limits to our knowledge of the world arise both from our tools of exploration and from the nature of physical reality: the speed of light, the uncertainty principle, the second law of thermodynamics, the incompleteness theorem, and our own limitations as an intelligent species. Our view of physical reality depends fundamentally on who we are and on how we interact with the cosmos. (shrink)

A single argument template---the EPH template---can be used to generate versions of the best known and most challenging skeptical problems. In his brilliantly groundbreaking book Knowledge and Its Limits, Timothy Williamson presents a theory of knowledge and evidence which he clearly intends to provide a response to skepticism in its most important forms. After laying out EPH skepticism and reviewing possible ways of responding to it, I show how elements of Williamson’s theory motivate a hitherto unexplored way of responding to (...) EPH-generated skeptical arguments. Then I offer reasons to doubt the correctness of Williamson’s response. (shrink)

Novo livro do autor do best-seller A simples beleza do inesperado, vencedor do Jabuti. O caldeirão é onde se misturam ingredientes visando sua transmutação. É o laboratório onde buscamos alguma forma de transcendência, o portal que nos transporta a uma nova realidade. Em O caldeirão azul, Marcelo Gleiser reúne ensaios provenientes de sua reflexão sobre as questões que considera mais relevantes para o momento atual: nossa relação com o planeta e suas criaturas, com os membros da sociedade em que (...) vivemos, e com a tecnologia, que está transformando quem somos e como nos relacionamos. O tema que conecta todos os textos é a visão da ciência como produto da nossa capacidade de nos maravilhar com o mundo toda vez que nos engajamos com o mistério da criação. Na sua essência, encontramos o mesmo ímpeto que move o espírito religioso: como lidar com nossas questões existenciais mais profundas, nossa origem, nossa vida, nossa morte. Nesta obra, Gleiser nos lembra que a ciência, aliada à nossa busca por respostas e nosso fascínio pelo mistério que nos cerca, pode ser usada tanto como ponte para um mundo melhor, como para construir a pior distopia imaginável. E nos convida a refletir – e decidir – sobre o futuro que queremos para nós, respeitando as diferenças de cada um e estando abertos para aprender com os que pensam de outras formas. (shrink)

Gianni Vattimo associates “mystic” and metaphysics. The “forgetting of the being” would be coextensive to the abandonment (Gelassenheit) or to the mystic “losing oneself” (Versenkung) in the absolute. Based on this, the article analyzes the relevance and the possibility of the vattimiana hermeneutics referring to (Verwindung) “the mystic” to surpass it. The perspective of the hermeneutic ethics of Vattimo defends that the history of modernity, in its nihilism and secularization, keeps traces of the history of the salvation inaugurated by the (...) Jewish-Christian perspective. The “mystical losing oneself” contradicts the Pauline experience of the preparation of parusía. Based on Heidegger, the Italian philosopher defends that, considering the imminent parusía, the authenticity of the temporal experience to the Pauline Christian, meant going through, with faith, the present tribulation in the caducity of the historical contingency, hindering the mystical Versenkung and its respective evasion in the daily efforts. In favor of this persistence/effort, it is glimpsed cáritas, inaugurated by the kénosis in the East, as the optimum authenticity criterion for a contemporary spirituality; because cáritas would imply, in its opposition to the implicit violence of the absolute fundamentals, the recognition of the bond between the spiritual and the nihilist and secularized East.

O artigo preconiza a relevância pedagógica da filosofia da não-significação de Albert Camus, especialmente em O Mito de Sísifo. O eixo argumentativo segue a última frase deste livro: “É preciso imaginar Sísifo feliz”. A certeza da existência e a estranheza de se inserir num cenário de catástrofe, sem esperança, suscita em estudantes, especialmente da rede pública, um “sentimento da absurdidade”, mas esse estado não há de ser visto como maldição. A liberdade paradoxalmente advém quando se assume o absurdo como meio (...) de se afirmar a vida, contra os suicídios físico e filosófico, tornando Sísifo o “herói absurdo”. Camus atribui ao pensamento de Søren Kierkegaard a proposta do suicídio filosófico como sacrifício do intelecto pelo salto kiekegaardiano da fé porque ele entende a felicidade encontrada na vida eterna como uma superação e cura da doença mortal do desespero. O esforço dialético de autorreflexão da consciência entre o finito e o infinito faz da resignação infinita uma preparação para o salto da fé. Para nosso autor, porém, o pior mal é não ter sofrido desespero, pois é a partir dele que imaginativamente o absurdo, como potência existencial, transfigura-se numa “revolta metafísica” — uma posição a ser desenvolvida no processo de ensino-aprendizagem em Filosofia. Palavras-chave: Albert Camus. Absurdo. Imaginação. Ensino de Filosofia. (shrink)

O livro almeja ser representativo nos principais debates contemporâneos, oferecendo uma visão panorâmica sobre o campo na atualidade e permitindo-se aprofundar em algumas discussões selecionadas.O ambiente não pode ser reduzido ao “meio ambiente”, à natureza não humana. Ele não é meramente algo que “nos envolve”, um envoltório: o ambiente somos também nós, seres humanos, histórica e culturalmente situados. Quanto aos territórios, eles se estabelecem em íntima conexão com os ambientes em suas dimensões paisagística e material, quer sejam os processos geoecológicos, (...) quer sejam as formas e as dinâmicas socialmente produzidas. Analisar os territórios significa examinar como, a cada momento, os ambientes, seus recursos e significados são disputados e viram objeto de conflitos.O público-alvo principal são os estudantes dos últimos anos da graduação, além daqueles em nível de pós-graduação, de todas as áreas que lidam com problemas e conflitos ambientais. Afora os pesquisadores iniciantes e os jovens universitários em geral, porém, podemos presumir que profissionais experientes também poderão tirar proveito do material de diversos capítulos. É razoável, por fim, nutrir a expectativa de que muito do que este livro contém possa (retro)alimentar o ativismo ambiental crítico e a prática de combater as iniquidades e as distorções que se acumulam em nossas sociedades, principalmente as muitas situações de flagrante injustiça ambiental.

This paper is an attempt to implement Gilles Deleuze's theory of the series and the event, and the related function of the empty square (as formulated primarily in The Logic of Sense), in relation to the geopolitical regime comprising ‘Israel proper’ and the system of occupation in the West Bank and the Gaza Strip. The purpose of this exercise is to help establish a practical access to Deleuze's philosophies, and to offer a clinical account of the Israeli occupation of the (...) Palestinian territories.

Michel Foucault is one of the most preeminent theorists of power, yet the relationship between his militant activities and his analysis of power remains unclear. The book explores this relationship to explain the development of Foucault's thinking about power. Using newly translated and unpublished materials, it examines what led Foucault to take on the question of power in the early 1970s and subsequently refine his thinking, working through different models (war and government) and modalities (sovereign, disciplinary, biopolitical, pastoral and governmental). (...) Looking at Foucault's political trajectory, from his involvement with the prisoner support movement and Solidarity to his controversial engagement with the Iranian revolution, the book shows the militant underpinning of his interest in the question of power and its various shifts and mutations. This thorough account, which includes the first translation of a report edited by Foucault on prison conditions, will provide students in contemporary political theory with a better understanding of Foucault's thinking about power and of the interplay between political activities and theoretical productions.

From Fall 2016 to Fall 2019 Marcelo Gleiser conducted a series of nine public dialogues between eminent scientists and humanists on challenging topics and ideas whose very definitions and meanings are disputed. Sponsored by the Institute for Cross-Disciplinary Engagement at Dartmouth College, founded by Gleiser, these events were held in theaters and universities across the US and immediately followed by workshops, open to the public, at which attendees could converse directly with participants. Great Minds Don't Think Alike collects edited (...) versions of these discussions, which set an example, in a time when public discourse is seriously threatened, of how people can engage in a fruitful exchange of ideas even when they strongly disagree. The cast of characters is stellar: David Chalmers and Antonio Damasio on consciousness, Sean Carroll and Alan Wallace on reality, Patricia Churchland and Jill Tarter on the future of intelligence, Rebecca Goldstein and Alan Lightman on faith, Jimena Canales and Paul Davies on time, Ed Boyden and Mark O'Connell on transhumanism, Elizabeth Kolbert and Siddhartha Mukherjee on immortality, and Jeremy DeSilva, David Grinspoon, and Tasneem Zehra Husain on being human.

L'œuvre de Michel Foucault est inclassable car elle traverse des domaines très variés (philosophie, sociologie, histoire, anthropologie, criminologie, médecine, psychologie, linguistique, droit, etc.). Foucault n'est pas un sociologue au sens classique du terme. Il existe une sociologie puissante et novatrice chez lui. Mais laquelle? À quoi peut-elle servir aujourd'hui? En quoi est-elle utile pour théoriser les problèmes sociaux? Quels sont ses avantages et ses inconvénients? Quel type de « raisonnement sociologique » se dégage de son œuvre et quelles sont ses (...) limites? Voilà les interrogations qui guident l'analyse de l'ensemble des travaux de Foucault dans cet ouvrage. En suivant l'évolution historique de ses recherches ainsi que les retournements stimulants de sa pensée, Foucault Sociologue s'organise en neuf chapitres qui suivent l'évolution théorique, méthodologique et chronologique des thématiques foucaldiennes. Marcelo Otero est professeur titulaire au Département de sociologie de l'Université du Québec à Montréal (UQAM), chercheur au Centre de recherche de Montréal sur les inégalités sociales, les discriminations et les pratiques alternatives de citoyenneté (CREMIS), au groupe sur le médicament comme objet social (MÉOS) et à l'Institut Santé et Société (ISS). Ses recherches portent sur les nouveaux problèmes de santé mentale et les problèmes sociaux complexes."--Quatrième de couverture. (shrink)

The subject of this book is the social and political meaning of constitutional texts to the detriment of their legal concretization. Focusing on the discrepancy between the hypertrophically symbolic function of constitutions and their insufficient legal concretization, it offers a critical counterpoint to constitutional theory that treats constitutional texts as a panacea to solving political, legal, and social problems. In contrast to the premises of Niklas Luhmann's systems theory regarding law and constitution in world's society, symbolic constitutionalization is approached here (...) in both a comprehensive and far-reaching perspective. Chapter 1 sets out the debate about symbolic legislation. Chapter 2 explains the notion of symbolic constitutionalization as a problem embracing the whole legal system. Chapter 3 approaches the issue in terms of allopoiesis of law, characterizing it primarily as a problem in peripheral modernity and referring to the Brazilian experience. The final chapter discusses the tendency to a symbolic constitutionalization of world society in the scope of a paradoxical peripheralization of the centre. (shrink)

No cinema brasileiro recente, o diálogo entre o documentário e a ficção tem merecido destaque, com produções de baixo orçamento e ideias originais. É o caso de Santiago (João Moreira Salles, 2007) e Viajo Porque Preciso, Volto Porque Te Amo (Marcelo Gomes, Karim Aïnouz, 2009), filmes que trabalham esse diálogo de forma sutil e diegética, ressignificando imagens de um arquivo próprio, pessoal.

Whilst he was writing De principatibus, was Machiavelli really as out of touch with the Florentine politico-institutional world as his letter of December 1513 claims? Who read Il principe prior to its publication, and how? Why did the philosopher Agostino Nifo, one of the major proponents of Renaissance Averroism, plagiarize it? To what extent is the Machiavellian "principato civile" comprehensible only by way of its Medicean and Florentine affiliation? Did the young Lorenzo de' Medici's political programme seek to eliminate the (...) Roman church? What politicocultural stance is hidden behind certain political terms from the humanist tradition that Machiavelli revisited in Il principe? To what extent was the Machiavellian relationship between animality and humanity, simulation and dissimulation, influenced by Leonardo da Vinci's ceuvre? And, finally, what are the questions that remain open in Il principe? This compilation offers some possible answers to these questions, thus providing new critical tools for the study of Niccolo Machiavelli's Il principe -- Back cover. (shrink)

Modern societies often claim to be democracies in order to enjoy greater legitimacy. Still, to understand the concept of democracy and how to justify it, the definition of it as self-determined is not sufficient. A complex understanding has to take into account ideas of rule of law as well as human rights. Sometimes these three concepts compete with each other - particularly in societies with a pluralistic approach to what "the good life" should be, such as societies which are made (...) up of distinct cultural backgrounds. This book presents a concept of democracy that encompasses at the same time the ideas of rule of law, human rights and self-determination. It contains the main lectures of the XXVI World Congress of Philosophy of Law and Social Philosophy, hosted by the Internationale Vereinigung fur Rechts- und Sozialphilosophie at the Universidade Federal de Minas Gerais (Brazil) in July 2013.

The book provides an overview of how international law is today constructed through diverse macro and microprocesses that expand its traditional subjects and sources, with the attribution of sovereign capacity and power to the international plane (moving the international toward the national). Simultaneously, national laws approximate laws of other nations (moving among nations or moving the national toward the international), and new sources of legal norms emerge, independent of states and international organisations. This expansion occurs in many subject areas, with (...) specific structures: commercial, environmental, human rights, humanitarian, financial, criminal, and labor law contribute to the formation of postnational law with different modes of functioning, different actors, and different sources of law that should be understood as a new complexity of law.

Part two of an innovative trilogy on anarchist geography, this text examines how we can better understand the ways in which space has been used for resistance.

In his important book Knowledge and Practical Interests, Jason Stanley advances a proposal about knowledge and the semantics of knowledge ascriptions which he calls interest-relative invariantism. A theory of knowledge ascriptions of the form ‘A knows that S’ is invariantist.
