Shape Dynamics is a radical yet soundly based reinterpretation of Einstein's theory of gravity that has opened up new approaches to gravity research. This text offers both a brief introduction and a detailed walk-through of the motivations for the theory, its development from first principles and an in-depth look at its present status.

Karl Popper and Paul Feyerabend were among the most influential philosophers of science of the twentieth century. Extensive studies have been dedicated to the development of their controversial relationship, which saw Feyerabend turning from a student and supporter of Popper to one of his harshest critics. Yet, it is not as well known that the rift between Popper and Feyerabend arose mainly in the context of their studies on the foundations of quantum mechanics, which has been the main subject of (...) their discussions for about two decades. This paper reconstructs in detail their diatribe over the foundations of quantum mechanics, emphasising also the major role that their personal relationship played in their distancing. (shrink)

O artigo propõe uma reflexão em torno aos desafios que emergem diante da luta pela preservação das comunidades tradicionais e populações originais dentro de um país onde impera o genocídio praticado nos espaços rurais a partir dos interesses de latifundiários, das grandes corporações do agronegócio exportador e de seus apoiadores.

The Renaissance perspective represents the three-dimensional space onto a bi-dimensional one. This cultural construction, which unifies real and virtual, like all simulations, has some limitations – the main one is that it only works from a precise viewpoint that rules the illusion. When moving away from this position the illusion becomes imperfect. Similar to physics, where reality depends on the observer’s position, perspective depends on the viewer’s position. Since perspective has been inherited by photography, cinema, video, computer images, virtual reality, (...) 3D videogames, we live in a perspective-based culture. In perception the boundaries between opposite qualities are often blurred and even indistinguishable. A screen is generally considered as rectangular, but it can be viewed as really rectangular only from its central perpendicular axis, at the crossing of the diagonals. When moving from this position it should appear as trapezoidal, but people still say it is rectangular: because they see it as rectangular or because they know it is rectangular? This threshold between vision and knowledge is imperceptible and obscure. Something similar happens with the senses. They are considered as separate entities: touch, hear, sight, smell and taste are described as distinct ways to detect the phenomenal world. But they are intermingled; the boundaries that are supposed to separate them are apparent: they are logically separable but not separate. The sensorial system is a cohesive and interrelated continuum where the senses act in synergy with each other. Continuity and discreteness, indistinguishability and distinction, inseparability and division are qualities to individuate, describe, classify and/or communicate the phenomena. These qualities are both theoretical and technical, since they depend on the general perspective of the analysis, on the goals to pursue, on the scale at which the phenomena are observed and on the accuracy of the instruments that are used.

‘Engineered’ and ‘organic’ have always represented two sides of a challenge that went along with human evolution. Since the dawn of its existence, humankind has been trying to adapt ‘Nature’, the phenomenal world, to his goals, through projects, techniques, instruments, devices, machines, in a process that received propulsion and acceleration from the advent of symbolic ability. Inside the phenomenal world, the ‘organic’ – the material carbon-based dimension on which life is founded, according to the sciences – has always represented a (...) very important subsystem, mainly the world of the living. The ‘organic’ as food, support, pleasure, invention, care, with human skill, has been developing since prehistory, to select, hybridize and breed animals and plants, through more and more successful techniques ranging from crossbreeding to genetic manipulation and engineering. But also as ways to take care of the human body and life with tools, dresses, signs, machines and medical treatments. Scientific evolution has led to the capacity to deeply modify existing organisms and create new ones, new species that would never have evolved naturally. One major technique to describe and simulate the world and to interoperate with Nature is digital technology. Artificial intelligence, artificial life and robotics are mainly digitally based, working at the edge of Nature and the engineered. Digitally based technologies such as 3D printing and the Internet of Things can get to an intimate relationship among the engineered, the organic and Nature, blurring the divide between matter and language, life and code, ‘hardware’ and ‘software’. Hence, through sciences and technologies humanity is creating a Third Life originating from knowledge and culture, which is independently and autonomously evolving, expanding Nature from inside the realm of Nature.

In the last few years holography has celebrated some important anniversaries: in 2010 the 50th anniversary of the light amplification by stimulated emission of radiation (LASER) invention; in 2011 the 40th anniversary of the Nobel Prize awarded to the Hungarian scientist Dennis Gabor for inventing holography and in 2012 the 50th anniversary of the first holograms. Holography can create an accurate visual simulation, with total parallax: a replica of the real object made of light, which has the real object’s visual (...) properties but is immaterial, intangible. The holographic images are volumetric and exist in a real and measurable space, and are not based on the Renaissance perspective, which can represent the three-dimensional physical space in a bi-dimensional one. In the near future, holography-based techniques will open up new possibilities in the visualization domain, allowing new visual worlds. In the meantime, holography can be a useful technical and theoretical tool for reflecting on how our everyday mediascape works. The media can produce, reproduce and transmit bi-dimensional images on flat supports. The media system has a high degree of coherence and the images share similar morphostructural rules, and thus can be transferred from one medium to another without any fundamental information loss: bi-dimensionality and image-support coincidently appear to be the basis of this high level of translatability. Conversely, holograms cannot be displayed through the usual media without losing their peculiarity: they require new displays, new visual media and new genres of communication, even if they hybridize with the existing media. Holography stands apart from the media realm, which in part explains the difficulties of this technique in emerging and integrating into the mediascape. Holography suggests a new visual universe within a culture where visual simulation is the most effective communication system, and it lets us reflect on the need for a more comprehensive definition of ‘image’. It is easy to imagine that future images will also be holographic and that we will communicate more and more through them, in a delicate balance between presence and absence, immediacy and remoteness, materiality and immateriality, matter and energy. Holography can work as a model in science, for example in the study of brain activity in the Holonomic Brain Theory, originated by Austrian psychologist Karl Pribram and initially developed in collaboration with physicist David Bohm to explain human cognition. Holography can also be a model in physics, for example in the idea of the physicist David Bohm of an ‘implicate order’ in the universe, where global structure can be found in each small part – the universe would be a gigantic and wonderfully detailed hologram. More recently, theoretical results on black holes suggest that the idea of a holographic universe is a viable hypothesis. And in the field of quantum gravity and string theories the ‘holographic principle’ suggests that the entire universe can be considered as a two-dimensional information structure, and that the three-dimensional world we observe is but a description at a macroscopic scale and at low energies.

Eu tinha uma sombra em mim, tão obscura que não a conhecia nem reconhecia. Nas sombras de mim mesmo ela se perdia. Só quando senti a sombra que em ti havia e me impedia de me aconchegar em ti, passei a suspeitar da extensa sombra que se estendia, assombrando a mente que eu tão lúcida pretendia.

Ter uma noção mais clara sobre o que possa ser a verdade é central não só para a ciência, também não só para a filosofia, mas também para a arte. Há uma longa tradição filosófica que diz, com Aquino, que o belo é o resplendor da verdade ou, com Hegel, que o belo é a aparição sensível da ideia. Para o idealismo alemão, a ideia tinha de ser verdadeira, pois se não ela seria apenas um palpite infeliz. Como a verdade (...) permite distinguir o que é justo e correto, o que vale e o que não tem valor, ela também é central para a vida das pessoas, para as grandes decisões que precisam tomar e para a estruturação do seu dia a dia.

In this paper, we reject commonly accepted views on fundamentality in science, either based on bottom-up construction or top-down reduction to isolate the alleged fundamental entities. We do not introduce any new scientific methodology, but rather describe the current scientific methodology and show how it entails an inherent search for foundations of science. This is achieved by phrasing metaphysical assumptions into falsifiable statements and define as fundamental those that survive empirical tests. The ones that are falsified are rejected, and the (...) corresponding philosophical concept is demolished as a prejudice. Furthermore, we show the application of this criterion in concrete examples of the search for fundamentality in quantum physics and biophysics. (shrink)

En la tradicción jurídica italiana siempre el derecho de la família y el derecho de la responsabilidad civil fueron distintos. Pero ahora la jurisprudencia, y tambien el legislador, estan introducendo los remedios aquilianos en la familia misma, entre marido y mujer y entre padres y hijos. El artículo quiere averiguar si es posible buscar una basis comun para esta nueva responsabilidad de los padres con la responsabilidad de los mismos para los daños que los niños hacen a los terceros.

Normal 0 21 The main goal of this paper is to maintain that the skeptical hypotheses in the First Meditation, and especially the doubt about material things, should be interpreted as a kind of mental exercise whose purpose is both to weaken our confidence in the senses and to prepare the reader of the Meditation for the learning of the truths accessible through the light of reason. Thus, the paper purports to show that in the economy of the Meditations skeptical (...) doubts play a positive and constructive role, which is distinct from their role of bringing about philosophical skepticism that prevails in contemporary epistemological debates. The strategy that allowed for this reading consisted in both valuing the emergence of skeptical doubts within a text written in a meditative style and highlighting certain aspects of the intellectual context that were part of the scientific revolution experienced by Descartes.

The standard interpretion of Hume's philosophy presents him both as a radical skeptic regarding rational claims about the adequate foundation of our belief system and as a naturalist who maintained that our beliefs (though rationally ungrounded) cannot be given up in ordinary life, due to natural drives and sentiments. This paper purports to show that Hume's naturalism can and should be interpreted as a method for addessing philosophical concepts (ideas and beliefs,to use Hume's jargon) that incorporates unreflected elements ofordinary life (...) (such as natural sentiments and drives) and assigns to them the same theoretical status that abstract processes such as reasons and arguments have. A philosophy that warrants unreflected mechanisms in the treatment of philosophical problems is what Hume calls a "true philosophy". Such philosophy is compatible with the more radical forms of skepticism, because the unreflected mechanisms that bring about ideas are imune to doubt. To ilustrate the theses put forth here and so as to render my characterization of naturalism more persuasive, I describe briefly and in broad terms at the end of the paper Hume's view of moral agency.

Desde a publicação, em 1958, do famoso artigo A Filosofia Moral Moderna de G. E. M. Anscombe estabeleceu-se uma espécie de consenso em torno da necessidade de as teorias ético-filosóficas contemporâneas ampliarem sua agenda de análise para além das noções de dever e obrigação. Esse movimento conduziu à redescoberta de concepções morais antigas ligadas à constituição de um caráter virtuoso e da conquista da felicidade ou bem-viver, especialmente a ética de Aristóteles e dos filósofos estoicos. Nesse artigo eu mostro que (...) a filósofa e escritora britânica Iris Murdoch participou desse movimento de redescoberta da ética das virtudes antiga, localizando na filosofia de Platão, e não na filosofia de Aristóteles ou dos estoicos, um instrumento de crítica às teorias morais de seu tempo, uma crítica caracterizada pela substituição da noção tipicamente moderna da vontade racional do agente por noções profundamente vinculadas à filosofia platônica, como o “amor” e “atração” pelo Bem, entendidos como constituintes de um modelo de orientação moral objetiva. Diferente de Platão, no entanto, o Bem e seu poder de engajamento e atração, é explorado como uma fonte ético-metafísica com um significado psicológico muito particular. Ele é caracterizado, em termos da psicologia moral de base psicanalítica por ela adotada, como um olhar amoroso do outro e como um desejo de ver a realidade, entendido como um desejo pessoal de sermos justos e bons, o que dá um sabor psicológico-naturalista à sua reinvindicação da filosofia platônica.

Ultimamente bastante atençáo vem sendo dispensada ao estudo do ceticismo moderado na modernidade. O famoso historiador da filosofia Richard Popkin, em sua História do Ceticismo de Erasmo a Espinosa , cunhou a denominaçáo de ceticismo epistemológico para qualificar os membros desta corrente e nela inseriu os filósofos setecentistas Gassendi e Mersenne, considerando-os seus principais representantes. Além disso, no século XVIII temos o denominado ceticismo mitigado de Hume, que chamou a atençáo dos filósofos modernos para definir os limites do ceticismo. Este (...) artigo procura contribuir para o estudo do ceticismo moderado na modernidade, mostrando náo só que Hume, Mersenne e Gassendi podem fazer parte do assim chamado ceticismo epistemológico ou mitigado, mas também que há certos elementos comuns em suas filosofias destinados a mitigar os argumentos dos céticos de seu tempo.

The capability approach developed by Nobel Laureate Amartya Sen has become an important new paradigm in thinking about development. However, despite its theoretical and philosophical attractiveness, it has been less easy to measure or to translate into policy. This volume addresses these issues in the context of poverty and justice. Part I offers a set of conceptual essays that debate the strength of the often misunderstood individual focus of the capability approach. Part II investigates the techniques by which we can (...) measure and compare capabilities, and how we can integrate them into poverty comparisons and policy advice. Finally, Part III looks at how we can apply the capability approach to different regions and contexts. Written by a team of international scholars, The Capability Approach is a valuable resource for researchers and graduate students concerned with the debate over the value of the capability approach and its potential applications.

The paper contains an axiomatic treatment of the intuitionistic theory of hereditarily finite sets, based on an induction axiom-schema and a finite set of single axioms. The main feature of the principle of induction used (due to Givant and Tarski) is that it incorporates Foundation. On the analogy of what is done in Arithmetic, in the axiomatic system selected the transitive closure of the membership relation is taken as a primitive notion, so as to permit an immediate adaptation of the (...) theory to cases of restricted induction (in particular primitive recursive induction). At the end of the paper several different forms of induction, which play an important role in the development of the theory, are compared. An alternative axiomatization of the theory, which is of intrinsic interest, is also discussed. (shrink)

ABSTRACT This article presents John Locke’s defence of toleration in the Epistola de Tolerantia and assesses the possibility of interpreting it as a vindication of a secular State. In particular, the goal is to analyse Locke’s distinction of the ends of Church and State and to determine to which degree it answers to the concept of laïcité formulated in the Universal Declaration of Laïcité in the 21st century.

Conceived as a textbook, this work is divided in three sections. In the first, the “Beginning of Moral Philosophy,” the author broaches the thorny issue of using moral practice as a springboard for the elaboration of a moral philosophy. To think of morals as a practice means to compare general norms with a particular kind of behavior. The author points out that moral judgments are not perceptions but rather judgments of practical reason, that is, judgments that apply moral principles to (...) particular circumstances. Insofar as they are moved by practical rationality, Abbá takes moral judgments as the starting point of moral research. Thus, moral philosophy has the task of justifying the immanent rationality of moral judgments, in order to ensure a harmony between the ends and the concrete realizations. According to Abbá, the transition from moral practice to moral philosophy arises from the fact that our conduct can be shaped and explained by way of philosophical elaboration. Proceeding in this direction, some unavoidable questions arise: What kind of person do I want to be? Who am I truly? The answers will supply the subiectum, that is, the subject matter of moral philosophy. (shrink)

Neste ensaio abordam-se dois temas principais: de um lado, o papel eminentemente central e paradoxal do conceito de mundo da vida na construção da teoria habermasiana centrada na atividade comunicativa; do outro, como esta concepção de mundo da vida pretende lançar as bases para uma via de análise da sociedade em geral. Tenta-se mostrar como o conceito de mundo da vida – que se estrutura e diferentes níveis - é fruto de um longo processo de reconstrução e de apropriações críticas (...) de princípios teóricos oriundos da filosofia e das ciências sociais, especialmente da teoria de sistemas, de Niklas Luhmann.
