Microagressões raciais são degradações e humilhações sutis, veladas, inócuas, feitas muitas vezes de forma intencional, proferidas contra indivíduos em nível local e individual. No Ensino Superior, pesquisas destacam que experiências com microagressões têm levado estudantes a abandonarem seus cursos. Nesse estudo, buscamos compreender a forma como estudantes cotistas negros e negras de cursos de Ciências Exatas vivenciam microagressões raciais em sua trajetória universitária. Para isso, apresentamos resultados relacionados a uma das categorias de análise de uma pesquisa em andamento, que se (...) relaciona às vivências de 40 estudantes com microagressões raciais dentro de um contexto acadêmico. Os respondentes sofreram microagressões raciais em salas de aula, laboratórios, em atividades de campo, e com docentes, demonstrando sentimentos de desmerecimento, exclusão, desconsideração, invalidez, e invisibilidade. Diante dos relatos, os estudantes combateram ou não tal fenômeno por meio de enfrentamento individual, enfrentamento em grupo, por representatividade, por apoio profissional e por silenciamento.

Neste artigo apresentamos resultados de uma pesquisa em que buscamos identificar as experiências de estudantes da área de Ciências Exatas com microagressões raciais. O público-alvo da pesquisa foi composto por estudantes beneficiários de ações afirmativas matriculados em cursos da área de Ciências Exatas da Universidade Federal de Alfenas (n=390) que responderam um instrumento denominado Escala de Experiências Acadêmicas, Sociais e de Sobrevivência no âmbito das Exatas (EASS-Exatas). Para a análise, utilizamos correlações e Spearman, teste de significância qui-quadrado e Análise de (...) Componentes Principais (ACP). Os resultados indicam que estudantes com idade entre 20 e 30 anos identificam com maior clareza aspectos relacionados às microagressões raciais. Além disso, os estudantes autodeclarados pretos foram aqueles que vivenciaram de forma mais intensa as microagressões raciais, inclusive com scores acima dos estudantes autodeclarados pardos, que também compõem o grupo de estudantes negros no Brasil. Isso evidencia que a cor da pele está diretamente relacionada às experiências com racismo e com microagressões raciais vivenciadas pelos estudantes. Mesmo vencendo a barreira do acesso, estudantes cotistas negros e negras de cursos de exatas continuam enfrentando o desafio de sobreviver academicamente devido a violência estrutural que vivenciam durante sua trajetória no curso e na universidade.

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.

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)

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.

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)

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.

To investigate the effects of two different modes of physical activity on body composition, physical fitness, cardiometabolic risk, and psychological responses in female adolescents participating in a multi-disciplinary program. The 12-week randomized intervention included 25-adolescents with overweight divided into two groups: sports practice-SPG and functional training-FTG. The SPG intervention was divided into three sports: basketball, handball, and futsal. SPG participants performed one sport 3-times/week, over the course of 1 month. The FTG performed concurrent exercises 3-times/week. This study was registered in (...) Clinical Trials Registry Platform under number: RBR-45ywtg and registered in Local Ethics Committee number: 2,505.200/2018. The intensity of physical exercises-PE was matched between groups by the rating of perceived exertion. The primary outcome was body composition, and secondary outcomes were physical fitness, cardiometabolic risk, and psychological responses. There was a significant time-effect for body mass, body mass index, and low-density lipoprotein, all being reduced. There were increases over time for musculoskeletal mass, aerobic fitness, and high-density lipoprotein. There was a group time interaction with body fat percentage being lower post-intervention in the SPG. No significant differences were observed for the other variables. Both physical activity models were effective in improving a subset of obesity-related health parameters. The findings should be extended by further investigation using more sophisticated measures of energy expenditure.Clinical Trial Registration:https://ensaiosclinicos.gov.br/, identifier: RBR-45ywtg.

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.

This is the first of four papers prompted by a recent literature about a doctrine dubbed spacetime functionalism. This paper gives our general framework for discussing functionalism. Following Lewis, we take it as a species of reduction. We start by expounding reduction in a broadly Nagelian sense. Then we argue that Lewis’ functionalism is an improvement on Nagelian reduction.This paper sets the scene for the other papers, which will apply our framework to theories of space and time. (So those papers (...) address the space and time literature: both recent and older, and physical as well as philosophical literature. But the four papers can be read independently.)Overall, we come to praise spacetime functionalism, not to bury it. But we criticize the recent philosophical literature for failing to stress: functionalism’s being a species of reduction (in particular: reduction of chrono-geometry to the physics of matter and radiation);functionalism’s idea, not just of specifying a concept by its functional role, but of specifying several concepts simultaneously by their roles;functionalism’s providing bridge laws that are mandatory, not optional: they are statements of identity (or co-extension) that are conclusions of a deductive argument, rather than contingent guesses or verbal stipulations; and once we infer them, we have a reduction in a Nagelian sense.On the other hand, some of the older philosophical literature, and the mathematical physics literature, is faithful to these ideas (i) to (iii)—as are Torretti’s writings. (But of course, the word ‘functionalism’ is not used; and themes like simultaneous unique definition are not articulated.) Thus in various papers, falling under various research programmes, the unique definability of a chrono-geometric concept (or concepts) in terms of matter and radiation, and a corresponding bridge law and reduction, is secured by a precise theorem. Hence our desire to celebrate these results as rigorous renditions of spacetime functionalism. (shrink)

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)

Gauge symmetries play a central role, both in the mathematical foundations as well as the conceptual construction of modern (particle) physics theories. However, it is yet unclear whether they form a necessary component of theories, or whether they can be eliminated. It is also unclear whether they are merely an auxiliary tool to simplify (and possibly localize) calculations or whether they contain independent information. Therefore their status, both in physics and philosophy of physics, remains to be fully clarified. In this (...) overview we review the current state of affairs on both the philosophy and the physics side. In particular, we focus on the circumstances in which the restriction of gauge theories to gauge invariant information on an observable level is warranted, using the Brout-Englert-Higgs theory as an example of particular current importance. Finally, we determine a set of yet to be answered questions to clarify the status of gauge symmetries. (shrink)

Phenomenal particularism is the view that particular external objects are sometimes part of the phenomenal character of perceptual experience. It is a central part of naïve realist or relational views of perception. We consider a series of recent objections to phenomenal particularism and argue that naïve realism has the resources to block them. In particular, we show that these objections rest on assumptions about the nature of phenomenal character that the naïve realist will reject, and that they ignore the full (...) resources that naïve realism has to offer in explaining phenomenal character.

The present paper is about the author’s current research on children’s education in urban contexts. It departs from the rising offer of programmes for school children in out-of-school contexts (e.g. museums, libraries, science centres). It asks what makes these practices educational (and not just interesting, entertaining and/or audience building). Based on Biesta ( 2006a , 2010 ) theory of education, the author frames and analyses the educational characteristics of, and possibilities of articulating, in and out-of-school educational practices. This paper aims (...) at understanding if the occasional outing from primary school premises promotes interruptions in the humanist foundations of school. In order to analyse relations between different institutions and professionals (to be) engaged in educational activities and programmes, Nóvoa ( 2002 , 2009 ) essays will be brought to the discussion, namely his conception of the ‘Public Space of Education’—as a space where culture, education, arts, sports and leisure are shared responsibilities, and where diverse institutions are networked aiming towards societal pluralism. I argue for the possibility of using cities’ public spaces as contexts with a worldly quality to complexify children’s education. Nevertheless, I draw attention to the unbearable educational lightness that these practices may carry if they do not go beyond the praise of chance; as well as to their unsustainable weight if they perpetually repeat school’s normal orders and add up rational discourses.

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)

Cet article propose un itinéraire de réflexion sur les fondements de l’éthique théologique en articulant trois contributions de Karl Barth à ce domaine : la définition de l’éthique comme l’impératif de l’indicatif qu’est la dogmatique, voire l’inséparabilité entre éthique et dogmatique qui place l’éthique à l’écoute de la révélation ; l’articulation d’un nexus christologique entre les catégories d’obéissance et de liberté comme « autodétermination déterminée » ; le débat sur l’Évangile et la Loi, comme révélation de l’histoire de la grâce (...) à partir de laquelle se déploie la grammaire d’une existence chrétienne. Cet itinéraire est entrecoupé par trois passages bibliques qui sont alignés sur les contributions de Barth : la vocation d’Abraham ; l’agonie de Jésus à Gethsémani ; la question posée à Jésus sur le bien qu’il faut faire pour entrer dans la vie éternelle. Nous suggérons que cet itinéraire biblique et barthien souligne qu’une éthique théologiquement construite conflue vers la christologie. (shrink)

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)

Seven informants , aged between 32 and 42, who had experienced at least one career change in their lives were interviewed about the history of their career trajectories. The interviews were analyzed according to the systematic and systemic reflexivity proposed by the phenomenological tradition: description, reduction and interpretation.

This would help both young people (...) and adults to see their own objectives more clearly and to be capable of formulating their own career plans and following them through. (shrink)

This paper investigates the implicative conditional, a connective intended to describe the logical behavior of an empirically defined class of natural language conditionals, also named implicative conditionals, which excludes concessive and some other conditionals. The implicative conditional strengthens the strict conditional with the possibility of the antecedent and of the contradictory of the consequent. $${p\Rightarrow q}$$ p ⇒ q is thus defined as $${\lnot } \Diamond {(p \wedge \lnot q) \wedge } \Diamond {p \wedge } \Diamond {\lnot q}$$ ¬ ◊ (...) ( p ∧ ¬ q ) ∧ ◊ p ∧ ◊ ¬ q. We explore the logical properties of this conditional in a reflexive normal Kripke semantics, provide an axiomatic system and prove it to be sound and complete for our semantics. The implicative conditional validates transitivity and contraposition, which we take to be integral parts of reasoning and communication. But it only validates restricted versions of strengthening the antecedent, right weakening, simplification, and rational monotonicity. Apparent counterexamples to some of these properties are explained as due to contextual factors. Finally, the implicative conditional avoids the paradoxes of material and strict implication, and validates some connexive principles such as Aristotle’s theses and weak Boethius’ thesis, as well as some highly entrenched principles of conditionals, such as conjunction of consequents, disjunction of antecedents, modus ponens, cautious monotonicity and cut.

Organisations are increasingly transforming themselves to remain profitable and obtain sustainable competitive advantages. Business processes are as important as technology in promoting organisational transformation. Organisational transformation ultimately entails combining existing business components, whether or not with the same use and design, with new ones to generate novel products and services. For example, one particular type of organisation transformation is digital transformation. This notion, which covers even the subjective aspects of organisational transformation, is currently under intensive discussion and suffers from the (...) semantics terms fluctuation related to the notion of ‘organisational transformation’. We argue that this topic could strongly benefit from an ontological analysis and conceptual clarification of these notions. This paper contributes with an attempt in this direction by proposing a Core Ontology of Organisational Transformation (COOT). This ontology comprises concepts and relations central to creating a reference model representing the organisational transformation paradigm. COOT was applied in a real-world case study on a car rental company. (shrink)

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.

O texto visa mostrar, a partir das análises do Roberto Schwarz e Georg Lukács, como a análise de lastro marxista autêntico é divergente da leitura meramente sociológica, procurando superar a dualidade “esteticismo x sociologismo”, dois reducionismos anti-dialéticos.

Para tanto, faremos uma primeira reflexão sobre o decurso lukacsiano (Georg Lukács) onde o autor, referência importante para Schwarz, deslinda a arte através, primeiramente, de posições Idealistas (arte em-si-mesmada) e, logo após, a partir da emergência e redescoberta gradual da ontologia marxiana.

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.

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)

Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist views cannot (...) account for the generality of visual experiences, and that the naïve realist explanation of particularity has unacceptable implications for self- knowledge: the knowledge we have of the character of our own experiences. We argue in this paper that neither claim is correct: naïve realism can explain the generality of experiences, and the naïve realist explanation of particularity raises no problems for our self-knowledge.

The historical formation of Brazil is distinguished from the majority of ex-colonial nations by one factor that is especially characteristic: an intense process of ethnic and cultural mixing. The Portuguese colonisers, who, unlike the English Puritans in North America, left their families and arrived in Brazil in small groups mainly composed of men, naturally tended to pair off with the women they found available - first of all indigenous women and later African women. There was nothing in Brazil to prevent (...) this spontaneous behaviour similar to the role played in the English colonies of North America by the strength of the family group or the strict religious observance of the community. Thus from the outset Brazil tended to accept racial mixing as a de facto reality. As Gilberto Freyre correctly noted in his book Casa Grande e Senzala:They mixed happily with women of colour from the very first contacts and many mixed-race children resulted, so much so that only a few thousand men were enough to colonize vast areas and compete with the greatest and most numerous peoples as regards the extent of the colonial territory and the effectiveness of colonizing activity.

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. Tal insuficiência crítica motivará, a partir de Luce Irigaray, que se ponha à prova o próprio modelo falogocêntrico da filosofia e da psicanálise, os quais se reinscreverão quando as mulheres repensarem a história do pensamento sob uma normativa feminista.
