O presente artigo tem por objetivo principal a exposição da teoria ontológica platônica sobre a definição de Ser e Não-Ser que se encontram no clássico diálogo “O Sofista”. Nesta obra, Platão usa uma série de raciocínios bem trabalhados e detalhados para se chegar à proposta popularmente conhecida como alteridade. Até chegar a esta conclusão, o filósofo caminha em direção aos sofistas e observa o que eles faziam a fim de expor sua verdadeira natureza, falha e demagógica, além da superação e (...) refutação da ontologia parmenídica para findar a sua independência filosófica.

Not all symmetries are on a par. For instance, within Newtonian mechanics, we seem to have a good grasp on the empirical significance of boosts, by applying it to subsystems. This is exemplified by the thought experiment known as Galileo’s ship: the inertial state of motion of a ship is immaterial to how events unfold in the cabin, but is registered in the values of relational quantities such as the distance and velocity of the ship relative to the shore. But (...) the significance of gauge symmetries seems less clear. For example, can gauge transformations in Yang-Mills theory—taken as mere descriptive redundancy—exhibit a similar relational empirical significance as the boosts of Galileo’s ship? This question has been debated in the last fifteen years in philosophy of physics. I will argue that the answer is ‘yes’, but only for a finite subset of gauge transformations, and under special conditions. Under those conditions, we can mathematically identify empirical significance with a failure of supervenience: the state of the Universe is not uniquely determined by the intrinsic state of its isolated subsystems. Empirical significance is therefore encoded in those relations between subsystems that stand apart from their intrinsic states. (shrink)

Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...) as a valid theorem in quantum theory. We then present what we take to be a better and more general gauge argument, based on Noether's second theorem in classical Lagrangian field theory, and argue that this provides a more appropriate framework for understanding how gauge symmetry helps to constrain the dynamics of physical theories.

Local gauge theories are in a complicated relationship with boundaries. Whereas fixing the gauge can often shave off unwanted redundancies, the coupling of different bounded regions requires the use of gauge-variant elements. Therefore, coupling is inimical to gauge-fixing, as usually understood. This resistance to gauge-fixing has led some to declare the coupling of subsystems to be the \textit{raison d'\^etre} of gauge \cite{RovelliGauge2013}. Indeed, while gauge-fixing is entirely unproblematic for a single region without boundary, it introduces arbitrary boundary conditions on the (...) gauge degrees of freedom themselves---these conditions lack a physical interpretation when they are not functionals of the original fields. Such arbitrary boundary choices creep into the calculation of charges through Noether's second theorem, muddling the assignment of physical charges to local gauge symmetries. The confusion brewn by gauge at boundaries is well-known, and must be contended with both conceptually and technically. It may seem natural to replace the arbitrary boundary choice with new degrees of freedom, for using such a device we resolve some of these confusions while leaving no gauge-dependence on the computation of Noether charges \cite{DonnellyFreidel}. But, concretely, such boundary degrees of freedom are rather arbitrary---they have no relation to the original field-content of the field theory. How should we conceive of them? Here I will explicate the problems mentioned above and illustrate a possible resolution: in a recent series of papers \cite{GomesRiello2016, GomesRiello2018, GomesHopfRiello} the notion of a connection-form was put forward and implemented in the field-space of gauge theories. Using this tool, a modified version of symplectic geometry---here called `horizontal'---is possible. Independently of boundary conditions, this formalism bestows to each region a physically salient, relational notion of charge: the horizontal Noether charge. Meanwhile, as required, the connection-form mediates an irenic composition of regions, one compatible with the attribution of horizontal Noether charges to each region. Thes aims of this paper are to highlight the boundary issues in the treatment of gauge, and to discuss how gauge theory may be conceptually clarified in light of a resolution to these issues.

Much has been written on witchcraft by historians, theologians, philosophers, and anthropologists, but nothing by scientists. This book aims to reappraise witchcraft by applying to it the advances in cognitive sciences. The book is divided into four parts. Part One: Deep History deals with human emotions and drives to deepen the phenomenology of evil witchcraft agency and its female feature. Part Two: Historical Times focuses on the natural control of malefice that engendered rare state and church repressions. Surprisingly, Islamic lands (...) remained immune from stakes. Modern urbanizations are considered a blow to the persistence of rural civilizations that embedded witchcraft in their vision. Part Three: In the Laboratory applies neurosciences to specific case studies such as the personalization of misfortune, the millenary stereotype witch=woman, the reality of evil, and the contagious meme of treasure hunts. Part Four: Millennials wonders whether intentional malefic hatred is a closed chapter in the history of humanity. An Anatomy of Witchcraft is ideal reading for students and scholars. Given its interdisciplinary nature, the book will be of interest to scholars from many fields including evolutionary psychology, anthropology, women's history, and cognitive sciences. (shrink)

This article aims to rethink the meaning of “nature” and the human in Plato, more specifically through some examples contained in the _Phaedrus_, a rare dialogue further away from the city. Phaedrus and Socrates leave Athens on a path outside the walls, past the Ilisus stream and the breeze of the woods, and end up sitting in the shadows of trees full of singing cicadas. What is the meaning of this scenario in the construction o the text? Is it possible (...) to learn from oak trees or insects? The philosophizing of this dialogue passes through the coolness of the shadows of the trees in the hot summer noon. This sensuous topography through the text reveals the writer Plato wary of the enveloping meaning of the living drama between Phaedrus and Socrates. The audience and participation of natural elements, trees and cicadas in the dialogue reveals an involvement of the discourse with the surrounding atmosphere, a special concern of Socrates in his palinode and in his final prayer to Pan. In this dialogue, more than distinct and removed from nature, we think the human being (and reason) immersed in it - in an attempt to integrate a mythological and dialogical search between river, rock, plants, animals, humans, gods and demigods. The image of an overly rationalist and humanist Plato finds in this text a perspective of an inspired writer, a hybrid poet and philosopher, with a mission to restore language and the city to animal and cosmic life.

Since communication and expression are central aspects of music performance it is important to develop a systematic pedagogy of teaching children and teenagers expressiveness. Although research has been growing in this area a comprehensive literature review that unifies the different approaches to teaching young musicians expressiveness has been lacking. Therefore, the aim of this article is to provide an overview of literature related to teaching and learning of expressiveness from music psychology and music education research in order to build a (...) new theoretical framework for teaching and learning expressive music performance in instrumental music lessons with children and teenagers. The article will start with a brief discussion of interpretation and expression in music performance, before providing an overview of studies that investigated teaching and learning of performance expression in instrumental music education with adults and children. On the foundation of this research a theoretical framework for dialogic teaching and learning of expressive music performance will be proposed and the rationale explained. Dialogic teaching can be useful for scaffolding young musicians’ learning of expressivity as open questions can stimulate thinking about the interpretation and may serve to connect musical ideas to the embodied experience of the learner. A “toolkit” for teaching and learning of expressiveness will be presented for practical application in music lessons. In addition, a theoretical model will be proposed to further our understanding of teaching and learning of expressive music performance as a multifaceted and interactive process that is embedded in the context of tutors’ and learners’ experiences and environment. Finally, implications of this framework and suggestions for future research will be discussed. (shrink)

After a brief introduction to issues that plague the realization of a theory of quantum gravity, I suggest that the main one concerns defining superpositions of causal structures. This leads me to a distinction between time and space, to a further degree than that present in the canonical approach to general relativity. With this distinction, one can make sense of superpositions as interference between alternative paths in the relational configuration space of the entire Universe. But the full use of relationalism (...) brings us to a timeless picture of Nature, as it does in the canonical approach. After a discussion of Parmenides and the Eleatics' rejection of time, I show that there is middle ground between their view of absolute timelessness and a view of physics taking place in timeless configuration space. In this middle ground, even though change does not fundamentally exist, the illusion of change can be recovered in a way not permitted by Parmenides. It is recovered through a particular density distribution over configuration space which gives rise to 'records'. Incidentally, this distribution seems to have the potential to dissolve further aspects of the measurement problem that can still be argued to haunt the application of decoherence to Many-Worlds quantum mechanics. I end with a discussion indicating that the conflict between the conclusions of this paper and our view of the continuity of the self may still intuitively bother us. Nonetheless, those conclusions should be no more challenging to our intuition than Derek Parfit's thought experiments on the subject. (shrink)

We review three broadly geometrodynamical---and in part, Machian or relational---projects, from the perspective of spacetime functionalism. We show how all three are examples of functionalist reduction of the type that was advocated by D. Lewis, and nowadays goes by the label `the Canberra Plan’. The projects are: the recovery of geometrodynamics by Hojman et al. ; the programme of Schuller and collaborators to deduce a metric from the physics of matter fields; the deduction of the ADM Hamiltonian by Gomes and (...) Shyam. We end by drawing a positive corollary about shape dynamics: namely, it has a good rationale for the Hamiltonian it postulates. (shrink)

Barbour’s interpretation of Mach’s principle led him to postulate that gravity should be formulated as a dynamical theory of spatial conformal geometry, or in his terminology, “shapes.” Recently, it was shown that the dynamics of General Relativity can indeed be formulated as the dynamics of shapes. This new Shape Dynamics theory, unlike earlier proposals by Barbour and his collaborators, implements local spatial conformal invariance as a gauge symmetry that replaces refoliation invariance in General Relativity. It is the purpose of this (...) paper to answer frequent questions about (new) Shape Dynamics, such as its relation to Poincaré invariance, General Relativity, Constant Mean (extrinsic) Curvature gauge, earlier Shape Dynamics, and finally the conformal approach to the initial value problem of General Relativity. Some of these relations can be clarified by considering a simple model: free electrodynamics and its dual shift symmetric formulation. This model also serves as an example where symmetry trading is used for usual gauge theories. (shrink)

O artigo procura considerar a fecundidade da ideia de arte e da própria criação artística no interior da prática filosófica de Marilena Chaui a partir de quatro pontos: i - a defesa de uma estética que não seja meramente pautada pelo julgamento de gosto e pela experiência do belo, mas por relações ativas entre arte, vida, crítica e engajamento social; ii - um parêntese de uma história pessoal que entrelaça política, ensino e literatura; iii - uma análise da escrita não (...) apenas filosófica, mas literária da autora, em uma comparação à própria escrita de Espinosa; iv - a importância da voz e da criação no ensino de filosofia de Chaui.

In an accompanying paper Gomes, we have put forward an interpretation of quantum mechanics based on a non-relativistic, Lagrangian 3+1 formalism of a closed Universe M, existing on timeless configuration space \ of some field over M. However, not much was said there about the role of locality, which was not assumed. This paper is an attempt to fill that gap. Locality in full can only emerge dynamically, and is not postulated. This new understanding of locality is based solely on (...) the properties of extremal paths in configuration space. I do not demand locality from the start, as it is usually done, but showed conditions under which certain systems exhibit it spontaneously. In this way we recover semi-classical local behavior when regions dynamically decouple from each other, a notion more appropriate for extension into quantum mechanics. The dynamics of a sub-region O within the closed manifold M is independent of its complement, \, if the projection of extremal curves on \ onto the space of extremal curves intrinsic to O is a surjective map. This roughly corresponds to \, where \ is a linear projection. This criterion for locality can be made approximate—an impossible feat had it been already postulated—and it can be applied for theories which do not have hyperbolic equations of motion, and/or no fixed causal structure. When two regions are mutually independent according to the criterion proposed here, the semi-classical path integral kernel factorizes, showing cluster decomposition which is the ultimate aim of a definition of locality.

Through a theoretical examination of the preventive turn in criminal law and justice which has gained momentum in Anglo-American criminal justice systems since the late-twentieth century, The Preventive Turn in Criminal Law demonstrates how recent transformations in criminal law and justiceare intrinsically related to and embedded in the way liberal society and liberal law have been imagined, developed, and conditioned by its social, political, and historical context. Henrique Carvalho identifies a tension between the idea of punishment as an expression (...) of individual justice, andprevention as a manifestation of the need for security and the promotion of welfare. Tracing this tension back to an intrinsic ambivalence within the modern conception of individual liberty, which is both repressed and preserved by liberal conceptions of responsibility and punishment, Carvalhoproves that as long as this ambivalence remains unexamined, liberal law has the potential to both promote and undermine individual justice.Engaging with the dominant contemporary literature on criminal law, prevention, risk, security, and criminalisation, this volume deploys a theoretical perspective developed through a critical analysis of both classical and contemporary works of social and political theory. The book reveals that thepervasiveness of prevention in 21st century criminal justice systems represents not only the consequence of new and unprecedented features of contemporary politics and society, but also the manifestation of essential aspects of the liberal legal and political tradition.

The article aims to reconstruct the seventeenth-century debate of the scientific nature of mathematics and the possibility of conceiving an idea of a positive infinite to address the philosophical implications of mathematics in Spinoza’s work, emphasizing the geometric ordering in his Ethics. We will approach the mathematical thinking of that philosopher from three perspectives: the pedagogical, the epistemological and the ontological. In the pedagogical sense, his synthetic geometry aims to inhabit the evidence as rhetorical and pedagogical expression of a perfect (...) and self-evident concatenation that leads the progress of the reader through philosophical propositions. In the epistemological sense, we have the aim of inhabiting the thing defined by a genetic definition that provides the very acting essence of a thing. That epistemological sense provides us the difference between a definition of a thing by its predicates or through its inner essence. And finally, in the ontological sense of inhabiting the infinite itself, because geometry can bring us the proper way to conceive the positive idea of the absolutely infinite in which we necessarily are and take part.

In this paper, we propose Kripke-style models for the logics of evidence and truth LETJ and LETF. These logics extend, respectively, Nelson’s logic N4 and the logic of first-degree entailment with a classicality operator ∘ that recovers classical logic for formulas in its scope. According to the intended interpretation here proposed, these models represent a database that receives information as time passes, and such information can be positive, negative, non-reliable, or reliable, while a formula ∘A means that the information about (...) A, either positive or negative, is reliable. This proposal is in line with the interpretation of N4 and FDE as information-based logics, but adds to the four scenarios expressed by them two new scenarios: reliable information for the truth and for the falsity of a given proposition.

ABSTRACTGrounded in Emotional Cascade Theory, we explored whether rumination and multisensory imagery-based cognitions moderated the relationships between affect and both odds of non-suicidal self-injury, and frequency of the behaviour. A sample of 393 university students completed self-report questionnaires assessing the constructs of interest. Contrary to expectations, rumination did not emerge as a significant moderator of the affect-NSSI relationship. However, the relationship between affect and frequency of NSSI was moderated by the use of imagery. Further, the relationship between negative affect and (...) NSSI was moderated by positive affect, underscoring the need to consider both negative and positive affect in models of NSSI. Most youth who self-injured reported thinking in images while the urge to self-injure was strong, with 53% thinking in images at least half the time. Future work is needed to explore how positive and negative affect work in concert to govern NSSI, and how imagery might eit... (shrink)

Na digressão da Carta Sétima (341c-d – 344d-e) Platão faz uma descrição do caminho filosófico e do limite dos discursos, sejam escritos ou falados, para se alcançar e comunicar o conhecimento dos seres e da virtude. A digressão critica a produção, por parte de Dionísio, jovem tirano de Siracusa, de um tratado sobre a filosofia platônica, visando suas ‘doutrinas’, como se já soubesse tudo sobre os princípios supremos da realidade. Nesse artigo pretendo ler a digressão acerca do conhecimento filosófico e (...) sua transmissão, não como um desvio do curso da Carta, mas como parte central para entender sua mensagem a filosofia platônica em geral– evidenciando através do texto suas múltiplas e importantes ligações com os diálogos.

The digression on knowledge in the platonic Seventh Letter Abstract: In the digression of the Seventh Letter (341c-d–344d-e) Plato describes the philosophical path and the limits of discourses, whether written or spoken, to reach and communicate the knowledge of beings and virtue. The digression criticizes the production, by Dionysius, a young tyrant of Syracuse, of a treatise on Platonic philosophy, aiming at its 'doctrines', as if he already knew everything about the supreme principles of reality. In this article I intend to read the digression about philosophical knowledge and its transmission, not as a deviation from the course of the letter, but as a central part to understand the message of the letter and of Platonic philosophy in general – evidencing through the text its multiple and important connections with the dialogues.

Describing a Mundus Novus was a very singular task in the sixteenth century. It was an effort shaped by a permanent inherent tension between novelty and normality, between the immense variety of new facts and the demand of credibility. How did these inner strains affect the narrative style of the first descriptions of the natural world of ‘the Indies’? How were the first European observers of the nature of America able to simultaneously transmit the idea of immensity and regularity, and (...) that of novelty? How did they attempt to describe new worlds knowing that there was a lot – perhaps too much – to tell? This paper focuses not on the much-discussed epistemological issues related to those questions, but on their narrative and stylistic consequences. We argue that the first Europeans meeting the new realities of the Americas or India had to meet new challenges, and these translated into texts with specific characteristics. Thus, their first descriptions are essentially different from the texts about the natural world that were written before or after the ‘discovery’. We show that they adopted very specific discursive approaches, and were deeply influenced by the credibility strategies of the medical profession in which they had been trained. (shrink)

This text represents our first attempting to offer a Metaphysic model to interpret the late modernity (which emerges in the middle of the 18th century and goes along until the end of the IIWW) through the concept of Teleontology. Thus, Teleontology means the procedure of the spirit of the late modern age to shift its paradigms from ontology (an investigation about the being as being, in which existence means an attribute) to teleology, in which essence must be conquered and revealed (...) in the final of a progressive process. Instead of Being, Man became the main object of this investigation; the question of the being as being has given way as to an enlightened concept of being-man (never reached) as also to the task to achieve this in order to satisfy what reason designed to human species. However, as this project of achieving the concept of Being-Man advanced, its true nature became clear: a unilateral and arbitrary colonial expansion, which forced everyone to follow Teleontological paradigms. Teleontology can demonstrate that Greek-Christian metaphysics means a particular element (never universal) submitted to a specific culture and, in this case, expresses the structure of Eurocentric thought that became global by way of the expanding of capitalism/colonialism. Specifically, in this text, we propose to investigate: 1 - what is Teleontology; 2 - what are its objects; 3 - what are its origins. (shrink)

The inherent difficulty in talking about quantum decoherence in the context of quantum cosmology is that decoherence requires subsystems, and cosmology is the study of the whole Universe. Consistent histories gave a possible answer to this conundrum, by phrasing decoherence as loss of interference between alternative histories of closed systems. When one can apply Boolean logic to a set of histories, it is deemed ‘consistent’. However, the vast majority of the sets of histories that are merely consistent are blatantly nonclassical (...) in other respects, and further constraints than just consistency need to be invoked. In this paper, I attempt to give an alternative answer to the issues faced by consistent histories, by exploring a timeless interpretation of quantum mechanics of closed systems. This is done solely in terms of path integrals in non-relativistic, timeless, configuration space. What prompts a fresh look at such foundational problems in this context is the advent of multiple gravitational models in which Lorentz symmetry is not fundamental, but only emergent. And what allows this approach to overcome previous barriers to a timeless, conditional probabilities interpretation of quantum mechanics is the new notion of records—made possible by an inherent asymmetry of configuration space. I outline and explore consequences of this approach for foundational issues of quantum mechanics, such as the natural emergence of the Born rule, conservation of probabilities, and the Sleeping Beauty paradox.

The eliminative view of gauge degrees of freedom—the view that they arise solely from descriptive redundancy and are therefore eliminable from the theory—is a lively topic of debate in the philosophy of physics. Recent work attempts to leverage properties of the QCD $$\theta _{\text {YM}}$$ θ YM -term to provide a novel argument against the eliminative view. The argument is based on the claim that the QCD $$\theta _{\text {YM}}$$ θ YM -term changes under “large” gauge transformations. Here we review (...) geometrical propositions about fiber bundles that unequivocally falsify these claims: the $$\theta _{\text {YM}}$$ θ YM -term encodes topological features of the fiber bundle used to represent gauge degrees of freedom, but it is fully gauge-invariant. Nonetheless, within the essentially classical viewpoint pursued here, the physical role of the $$\theta _{\text {YM}}$$ θ YM -term shows the physical importance of bundle topology (or superpositions thereof) and thus counts against (a naive) eliminativism.

We develop some ideas about gauge symmetry in the context of Maxwell’s theory of electromagnetism in the Hamiltonian formalism. One great benefit of this formalism is that it pairs momentum and configurational degrees of freedom, so that a decomposition of one side into subsets can be translated into a decomposition of the other. In the case of electromagnetism, this enables us to pair degrees of freedom of the electric field with degrees of freedom of the vector potential. Another benefit is (...) that the formalism algorithmically identifies subsets of the equations of motion that represent time-dependent symmetries. For electromagnetism, these two benefits allow us to define gauge-fixing in parallel to special decompositions of the electric field. More specifically, we apply the Helmholtz decomposition theorem to split the electric field into its Coulombic and radiative parts, and show how this gives a special role to the Coulomb gauge (i.e. div \((\mathbf{A}) = 0\) ). We relate this argument to Maudlin’s (Entropy, 2018. https://doi.org/10.3390/e20060465 ) discussion, which advocated the Coulomb gauge. (shrink)

Este artigo busca expor a sutileza da diferença entre o antigo e o novo, entre o arcaico e o moderno, a fim de questionar o caráter emancipatório da política na modernidade. A existência e a conjectura de um contrato sexual nas variadas formas da teoria do contrato social é o contexto no qual Carole Pateman desenvolve sua obra para expor a subversiva maneira com que as mulheres têm sido estimadas desde os primórdios da modernidade. O que é posto em questão, (...) contudo, é o fato de que a crítica de Pateman, embora de maneira exitosa rejeite o contratualismo, por outro lado não supera a estrutura discursiva da própria tradição jusnaturalista.

In the XXth century, the development of science has posed new challenges to the physicists. Waves have exhibited a corpuscular behavior while particles have exhibited undulatory behavior, but never simultaneously. This difficulty led Bohr to adopt the principle of complementarity, the figure by which the contradiction between wave and corpuscle is fixed. Thus the opposition between wave and corpuscle is absolutized. I think it was the non-consideration of dialectics that prevented Bohr from advancing towards the resolution of that objective contradiction, (...) that was about to be reflected on the theory.Consequently, it is the objective reality, in its unity and as a contradictory totality, that is removed from the theory. The scientific theory gives up the search for the internal connection of phenomena and its task becomes the mere ordination of such phenomena.The repression of the internal contradiction of reality has a second consequence in Bohr’s thought: objectivity becomes internal to language and it is considered under the figure of intersubjectivity. In fact, Bohr, by puting the correlation between object and measuring instrument as the instance in which knowledge is founded, is denying the possibility that there is a content of human representations that does not depend on the subject, i.e. is denying the possibility of objectivity.These are the general guidelines on which I will argue.
