The first work that René Descartes wrote was the Compendium Musicæ in 1618, this was his first experiment with the future cartesian method. As a work of youth, the author must have studied music in your education, mainly in the college of La Flèche. Conventionally, the work of Gioseffo Zarlino had been considered the main source, because was cited in the Compendium. Since the text starts with music´s definition and eight propositions, about which the rest of work was developed; check (...) the way that them appear in other treatises of the time could help to deduce the possible musical sources that the author used.This dissertation starts with a necessary reconstitution of philosophical and musical context of the epoch, followed by an analysis of jesuits conceptions of knowledge and music. In this way, it can be considered what motivated the author to write about music, as his the debates. In resemblance to his mature work, the text proposes a methodological turn that is only perceived with the context of the time in mind. After an interpretation of the definition of the music and the eight propositions, it could be possible compare with the others works form the epoch to verify his musical sources. With this process, it could evidence the influence of Aristotle, Aristoxenus, Jean de Murs, Pontus de Tyard, Gioseffo Zarlino and Francisco de Salinas. (shrink)

Este trabalho é uma investigação sobre os conceitos de espaço presentes tanto no livro IV da Física de Aristóteles, bem como no Livro 1, parte 2, do Tratado da Natureza Humana de David Hume. Nosso ponto de partida são os paradoxos de Zenão. Sabemos que Aristóteles debate diretamente com Zenão no livro IV da Física, enquanto Hume, no Tratado da Natureza Humana discute com a posição de Zenão acerca do espaço renovada por Bayle. Tendo isto em vista, o principal objetivo (...) deste trabalho é o de expor como Aristóteles enfrenta o paradoxo proposto por Zenão acerca do lugar, e como Hume enfrentou o paradoxo proposto por Bayle sobre a constituição do espaço, através de uma apropriação do método de Zenão.

ABSTRACT The disparity in the venezuelan demographic transition is a fact known by experts. On this setting, there are four municipalities in Falcón State with a high elder population, one of them is Tocópero. This research had as general objectives to study the estimations of demographic risks and the social politics for elders, people who are 75 and more, from Tocópero Municipality, considering that specialists indicate that, once the demographic oldness has arrived, it is important to study thoroughly the elder (...) population in order to design relevant politics and programs, taking into consideration that it is a vulnerable group. It was an exploratory and descriptive study, with a field-no experimental-transectional design. The sample was intentional. Structured interviews and questionnaires were applied to elders and municipal officials. The data processing was carried out by using quantitative methods. The conclusions indicated that the elder population in Tocópero Municipality had a marked female tendency. In general terms, the adverse effects associated to the estimations of demographic risk were not present in the studied sample. There was no relation between the demographic reality of this municipality and the social politics and programs implemented. The programs concentrated the elder and suppressed the intergenerational contact; the centralism was the key element to understand the present politics of the Venezuelan state towards the oldness. The demographic oldness of this municipality was determined by the way in which the birth of the municipality was approved. (shrink)

This article discusses the precariousness of labor relations in Brazil, focusing on the concept of “Uberization”. To this end, an analysis is made of the Brazilian sociological reality concern-ing formal and informal work relationships, seeking to understand the said problem and its implications for the social subjects directly involved with this new form of work. Thus, a map-ping of specialized theoretical production is used to account for the discussion of recent transformations in capitalism and modes of production in a critical (...) and current way.

Com o propósito de analisar a relação entre ser e movimento a partir dos conceitos de ato e potência, elaboramos um mapeamento do livro Θ da Metafísica, capaz de orientar o entendimento de sua estrutura central. Visto como um dos modos de se dizer o ser, o ser em ato e em potência é parte integrante e fundamental da investigação metafísica. A distinção entre ser em ato e em potência pretende resolver o clássico problema do não-ser que vem a ser, (...) mostrando como o não-ser é apenas não-ser ainda em ato, mas já é ser em potência e este guarda as condições para sua necessária atualização. A reconstrução argumentativa de Θ procurou ressaltar três aspectos principais: (1) Ato e potência funcionam como um elemento de conexão entre as outras ciências – práticas, produtivas e teóricas – que são subordinadas à Ciência do Ser enquanto Ser, a Metafísica. (2) Há uma forte relação entre o par conceitual ato/potência e os outros conceitos fundamentais da filosofia aristotélica, tais como: substância, forma, matéria, ação, bem, natureza e fim. Desse modo, ato e potência somente serão plenamente compreendidos se também forem considerados esses outros conceitos. (3) Há uma relação direta entre os dois sentidos em que ato e potência podem ser entendidos - o cinético e o metafísico - e a seguinte divisão interna de Θ: de Θ1 a Θ5 a investigação está centrada sob o ângulo do movimento, é o momento cinético, em que Aristóteles dedica-se mais à análise da potência caracterizada como um princípio de movimento.

An objective of thisthesis is to investigate whether philosophical tradition can justify or support some of the arguments that are at the basis of Leibniz’s system (for example, monads have no window to the exterior world, a phrase that summarises the structure of Monadology). I shall demonstrate how Leibniz reflects the concerns and the positions of his key predecessors. Thus, the aim of the thesis is to explore key antecedents to Leibniz’s central doctrines. The thesis argues that Leibniz carried out (...) a logical development of some principles in the eclectic system of Plotinus, which resulted in the structure of Monadology. Whether Leibniz’s project was successful or not will depend on how we view those principles. (shrink)

Esta tesis estudia el pensamiento del conservador español Juan Donoso Cortés (1809- 1853). Más precisamente, se ocupa de responder cómo resuelve el problema de la decadencia de la autoridad monárquica en Europa a partir de las revoluciones de 1848. Para abordar este objetivo general elaboramos dos objetivos específicos. El primero busca señalar las continuidades y discontinuidades de la obra donosiana, escindida generalmente en dos períodos: el juvenil, con un Donoso Cortés liberal, y el maduro, que luego de una “conversión religiosa” (...) se vuelca hacia el catolicismo reaccionario. El segundo objetivo hace foco en el concepto de dictadura, bajo la sospecha de que en esta noción reside la clave de su proyecto conservador. Con esto en mente construimos dos hipótesis. La primera afirma que nuestro autor es consciente de la imposibilidad de restituir el proyecto monárquico. La segunda, sugiere la presencia de una fórmula parcialmente decisionista como alternativa a dicho proyecto. Luego de un trabajo de lectura de primera mano de los textos donosianos, las conclusiones confirman las hipótesis y observan que existe una continuidad estructural en las ideas del español, pero también que hay discontinuidades, de las cuales la más importante es su particular noción de dictadura, que denominamos dictadura catolizante.

El presente artículo explora la relación entre las ideas estéticas y las ideas políticas en la obra de Edmund Burke. De dicho análisis, surge, en primer lugar, la relevancia de sus reflexiones sobre las nociones de lo bello y de lo sublime para la teoría política, usualmente desestimadas por los comentadores. En segundo lugar, la afirmación de que la idea de lo sublime es una característica imprescindible de todo gobierno político, y el trazado, en tercer lugar, de una distinción entre (...) los gobiernos moderados y despóticos a partir de las diferencias estéticas observables en la monarquía constitucional inglesa y la asamblea nacional revolucionaria de 1789. Se concluye la dependencia recíproca de ambas disciplinas para comprender con mayor exactitud el pensamiento del autor irlandés. (shrink)

Abstract: Alienation and slavery from Precious or what we don't want to see. It is our purpose to establish, in a parallel reading, these two films (highly rewarded), namely The Fence and Precious, that apparently being so different, are an illustration of the reality of life and the modern democratic world: the social uprooting and slavery. If in the movie of Phillip Noyce and Christone Olsen The Fence, is told a story of three young Aboriginal girls who are forcibly taken (...) to be transformed into domestic slaves, in the movie of Lee Daniels Precious, the young woman is already a servant in her own home and seeks the transformation of her life. Uniting these two stories, we find fundamental elements: illiteracy, ill-treatment, the idea of a migration (real or metaphysical), among others, but whose fundamental notion is the journey. If the film The Fence, the fence itself is used to conduct the three young Aboriginal to a real reunion with the family, in Precious, the metaphorical ‘fence’ is the limit of her world. From this interpretation, we will undertake our reflection about what we consider to be the alienation of the modern world and the silence we produce about them. (shrink)

Neste texto trato da possibilidade de defender uma “ontolo- gia da singularidade” e seus reflexos no problema do conhecimento, bem como de oferecer uma introdução à questão da linguagem, todos estes problemas compreendidos como elementos de interesse no pensamento de Ludwig Feuerbach (1804-1872), restringindo-me a uma investigação situada nos limites de Zur Kritik der Hegelschen Philosophie (1839). Em primeiro lugar procuro desenvolver a demarcação con- ceitual do que chamo de “ontologia da singularidade”, pressuposto a partir do qual coube a Feuerbach (...) empreender uma rearticulação da filosofia com a realidade material concreta, e as implicações desta questão para o tema do conhecimento. Em segundo, proponho que estes problemas parecem vir de algum modo relacionados a uma discussão sobre a linguagem, concebida como meio de expressão do pensamento. -/- This text deals with the possibility of defending “ontology of singularity” and its reflexes on the problem of knowl- edge, as well as offering an introduction to the question of language, all these problems understood as elements of interest in Ludwig Feuerbach’s thought (1804-1872), what bounds the investigation to the limits of Zur Kritir der Hegelschen Philosophie (1839). It seeks, firstly, to develop the conceptual demarcation of what is called here in this work “ontology of singularity”, on the basis of which it was up to Feuerbach to come up with the reartic- ulating of philosophy with concrete material reality, including the implications of this question for the theme of knowledge. On a second hand, it is proposed that these problems seem to come in some way from a discussion of language conceived as a means of expressing thought. (shrink)

This is the first record of nesting in the soil by the ant Camponotus sericeiventris (Guérin-Méneville, 1838), which has arboreal habit. The study was conducted in southeastern Brazil, in an ant colony located in a subterranean site. This study describes, for the first time, the ability of this arboreal species to vary its nesting site by the occupation of an unusual place in an urban environment; and this study demonstrates that this species is an interesting model for studies in urban (...) environments.

This article intends to show that the defense of ‘‘understanding’’ as one of the major goals of science education can be grounded on an anti-reductionist perspective on testimony as a source of knowledge. To do so, we critically revisit the discussion between Harvey Siegel and Alvin Goldman about the goals of science education, especially where it involves arguments based on the epistemology of testimony. Subsequently, we come back to a discussion between Charbel N. El-Hani and Eduardo Mortimer, on the one (...) hand, and Michael Hoffmann, on the other, striving to strengthen the claim that rather than students’ belief change, understanding should have epistemic priority as a goal of science education. Based on these two lines of discussion, we conclude that the reliance on testimony as a source of knowledge is necessary to the development of a more large and comprehensive scientific understanding by science students.

The Neoplatonic commentaries on Aristotle’s works have always been considered somehow suspicious. That is partly related to the doctrinal commitments of the commentators, partly with the hermeneutical strategies to which they seem to recur. Both of these reasons have also give place to the accusation of distortion and misunderstanding of Aristotle’s philosophy. In the following paper I want to perform an exercise of disclosing the hermeneutical procedure that one of this commentators applies to one of the passages of the first (...) book of the De Anima. The commentator is Philoponus, the passage is the refutation of the soul-harmony theory. My aim is to show that, despite the doctrinal commitments that the commentator may have, his methodology follows Aristotelian guidelines. I hope that this could open perspectives on the value that the commentators must have as philosophers, rather than merely interpreters or paraphrasers. (shrink)

O presente artigo pretende abordar o conceito de trágico, entendido como elemento principal ou elemento orquestrador do projecto nietzschiano em busca de uma determinação para uma nova forma de existência estética. Objectivo do autor é, pois, em primeiro lugar, explicitar o sentido da nova existência estética tal como Nietzsche, pela mão de Zaratustra, imputa à figura do Übermensch, o qual estabelece um projecto de justificação estética; em segundo lugar, trata-se de mostrar que o conceito de 'trágico'está estreitamente relacionado com o (...) conceito metafísico de 'eterno retorno'de tal modo que isso pretende, por um lado, ultrapassar a dimensão determinada da vida humana em algo maior ou melhor, e, por outro, visa a completa realização da vida humana que pode ser repetida, salientando que este movimento de repetição afirma o retorno dionisíaco do trágico. Objectivo do autor do artigo é, assim, provar que o projecto nietzschiano anuncia o Übermensch como uma nova forma de existência estética, ao mesmo tempo que recupera os conceitos de 'trágico' e 'dionisíaco', conceitos estes que animam a obra Die Geburt der Tragödie. Consequentemente, trata-se de ver até que ponto o Übermensch está afirmado como objectivo necessário e primário neste projecto, o qual permanece, contudo, uma herança enigmática em que nos deixa a filosofia de Nietzsche. /// The present article presents a brief approach to the concept of the 'tragic' understood as a main element or a conducting element in the Nietzschean project that searches for a determination of a new form of aesthetic existence. The author aims, thus, at two things: first, to explicit the meaning of this new aesthetic existence that Nietzsche, by the hand of Zarathustra, imputes to the figure of the Übermensch, which establishes a project of aesthetic justification; secondly, to show that the concept of the 'tragic' is closely related to the metaphysical concept of the 'eternal return' in such a way that it purposes, on the one hand, to surpass a determined dimension of human life into something bigger or better, and, on the other, to bring about a complete realisation of human life that can be repeated, so that the movement of repetition qffirms the dionysiac return of the tragic. The goal of the article is, moreover, to prove that the Nietzschean project announces the Übermensch as a new form of aesthetic existence while recovering the main concepts of 'tragic' and 'dionysiac', concepts that animate the book Die Geburt der Tragödie. Therefore, we shall see how the Ubermensch is placed as a necessary and prime objective in this project, which remains part of the enigmatic legacy with which Nietzsche's philosophy leaves us.

Pretendemos com este ensaio fazer uma bordagem à filosofia fenomenológica da linguagem de Heidegger; abordagem que procura realizar, senão mesmo justificar, isso mesmo que subjaz a uma linguagem que é doação, que é fazer vir à presença aquilo que é nomeado. Mas linguagem tem um sentido mais lato que não apenas fala ou falado. Linguagem como ‘dizer’. Um ‘dizer’ que se escuta para lá do simples dito, para lá de qualquer modo de ser do dasein (autêntico ou inautêntico), para lá (...) do quotidianamente falado. Ou seja, o que permite tornar perceptível e inteligível as sentenças “o homem fala” e, “die sprache spricht”, o que permite dizer que o dasein é aquele que só pode advir através da linguagem mas simultaneamente é aquele pelo qual só o ser pode falar, é aquilo que apelidámos de ontopotencialidade. Tendo a linguagem esta ontopotencialidade, i.e., a potencialidade de doação permanente, de permitir um acontecer possibilitante de mundo(s) que instituem uma abertura, ela possibilita a manutenção dessa mesma abertura. Eis a tarefa do nosso ensaio. Dividimos assim a nossa comunicação em três partes, a saber: 1) A origem necessária: Logos – O discurso como mostração; 2) Linguagem e Poesia – A essência da arte e a arte da essência; 3) A Ontopotencialidade da linguagem – definição e síntese.

State of art paper on the topic causation, around the problem of the nature of causation. Central theories of contemporary philosophical literature are discussed and analysed, namely, regularity theories of Hume and Mackie, counterfactual theories of Lewis, probabilistic theories of Reichenbach, Lewis and Menzies and causal processes theories of Salmon and Dowe.

Opinionated state of the art paper on scientific explanation. Analysis and discussion of the most relevant models and theories in the contemporary literature, namely, the deductive-nomological model, the models of inductive-statistical and statistical relevance, the pragmatic theory of why questions, the unifying theory of standard arguments, and the causal/non-causal counterfactual theory.

Opinionated state of the art paper on mathematical explanation. After a general introduction to the subject, the paper is divided into two parts. The first part is dedicated to intra-mathematical explanation and the second is dedicated to extra-mathematical explanation. Each of these parts begins to present a set of diverse problems regarding each type of explanation and, afterwards, it analyses relevant models of the literature. Regarding the intra-mathematical explanation, the models of deformable proofs, mathematical saliences and the demonstrative structure of (...) mathematical induction are addressed. Regarding the extra-mathematical explanation, modal, abstract and deductive models are addressed. (shrink)

The idea of Culture led by Social Sciences presents emotions as if they were difficult to measure, and consequently, from the point of view of the interpretation of Cultural Practices, bothering. The secondarysation (and even, the marginalisation) of emotions among the interpretaive arguments, is linked to a linear and diachronical perspective on the social fact, more than to a forgotten aspect. The traditional ethnographer’s incapacity on including emotional worlds in their reaserches produces traces of a fake objectivity and it is (...) the source of important inexactitudes (or even falsations). -/- Along three reaserches about Urban Culture, introduced in the context of the Sociocultural Process Workshop of the La Universidad del Zulia (“The Affective Dispositifs of Hugo Chávez’ Phenomenom”, “The Opprobium Laberynth: Sexual Chanceros in Maracaibo” and “Walking Throught the Night, Things Get Confused. Reflections about Transgendered, Body and Power in Maracaibo”), it is possible to see conditions for resolving some aspects obout meaning/sense and emotions/intellect tensions, using the body as an emotional territory and as an ethnographical resource. Those reaserches try to evaluate the affective consistence of the urban territory, from the transgendered’s street fronteers, from chanceros and from the “no deviated” society, until the Chávez’ phenomenom, throught the corporal imago between the subjects and the reaserchers. -/- At the end, it is possible to conclude about some useful principles of the idea of Culture that sees the body as a bridge to the missed subjectivity of knowledge.

Social wasps are broadly distributed in Brazil, and their distribution is closely related to local plant composition. However, only a few studies on the diversity of these insects have been carried out in northeastern Brazil, and in Caatinga Biome the diversity is probably underestimated due to the lack of inventories for the region. Aiming at advancing the knowledge about the wasp fauna, we carried out this study from October 2005 to September 2006 in Ibipeba, northeastern Brazil. We collected 172 wasps (...) of five genera and eight species, and recorded Polybia ruficeps Schrottky, 1902 for the first time in the state of Bahia. The most abundant species was Polybia ignobilis (Haliday, 1836) (n = 69), and the least abundant were Brachygastra lecheguana (Latreille, 1824) (n = 2) and Polistes canadensis (Linnaeus, 1758) (n = 2). The present study inventory focused exclusively on the diversity of social wasps in an area of Caatinga, which contributes to advance the local fauna knowledge. (shrink)

This paper explores the contrast between two meanings of thinking: (i) one implied by the Cartesian and Kantian philosophy, the two thinkers that have arguably the deepest influence on the constellation of Western philosophical problems and (ii) another implied by the philosophical-anthropological project of the Brazilian anthropologist Eduardo Viveiros de Castro. The thesis here defended is that, in the Cartesian and Kantian philosophy, thinking is related to ruling and legislating over the experience through concepts, while in Viveiros de Castros' (...) theoretical enterprise, thinking is rather to explore the limits of conceptual constructions when confronted with the experience of alterity.

Relies on two historical events: the framing of the universal declaration of human rights and recent emphasis on global justice.

Protopolybia sedula is a social swarming wasp, widely spread throughout many countries in the Americas, including most of Brazil. Despite its distribution, studies of its behavioral ecology are scarce. This study aimed to describe its foraging activity and relation to climatic variables in the city of Juiz de Fora in southeastern Brazil. Three colonies were under observation between 07:00 and 18:00 during April 2012, January 2013, and March 2013. Every 30 minutes, the number of foragers leaving and returning to the (...) colony was registered along with air temperature and relative humidity. Activity began around 07:30¸ increased between 10:30 and 14:30, and ended around 18:30. A mean of 52.7 exits and 54 returns were measured every 30 minutes. The daily mean values were 1,107 ± 510.6 exits and 1,135 ± 854.8 returns. Only one colony showed a significant correlation between forager exits and temperature (rs = 0.8055; P < 0.0001) and between exits and relative humidity (rs = -0.7441; P = 0.0001). This paper shows that climatic variables are likely to have little control on the foraging rhythm of P. sedula when compared to other species, suggesting the interaction of other external and internal factors as stimuli of species foraging behavior.

How is it possible that beginning from the negation of rational thoughts one comes to produce knowledge? This problem, besides its intrinsic interest, acquires a great relevance when the representation of a knowledge is settled, for example, on data and automatic reasoning. Many treatment ways have been tried, as in the case of the non-monotonic logics; logics that intend to formalize an idea of reasoning by default, etc. These attempts are incomplete and are subject to failure. A possible solution would (...) be to formulate a logic of the irrational, which offers a model for reasoning permitting to support contradictions as well as to produce knowledge from such situations. An intuition underlying the foundation of such a logic consists of the da Costa's paraconsistent logics presenting however, a different deduction theory and a whole distinct semantics, called here "the semantics of possible translations". The present proposing, following our argumentation, intends to enlight all this question, by a whole satisfactory logical point of view, being practically applicable and philosophically acceptable.Como é possível que a partir da negação do racional se possa obter conhecimento adicional? Esse problema, além de seu interesse intrínseco, adquire uma relevância adicional quando o encontramos na representação do conhecimento em bases de dados e raciocínio automático, por exemplo. Nesse caso, diversas tentativas de tratamento têm sido propostas, como as lógicas não-monotônicas, as lógicas que tentam formalizar a ideia do raciocínio por falha . Tais tentativas de solução, porém, são falhas e incompletas; proponho que uma solução possível seria formular uma lógica do irracional, que oferecesse um modelo para o raciocínio permitindo não só suportar contradições, como conseguir obter conhecimento, a partir de tais situações. A intuição subjacente à formulação de tal lógica são as lógicas paraconsistentes de da Costa, mas com uma teoria da dedução diferente e uma semântica completamente distinta . Tal proposta, como pretendo argumentar, fornece um enfoque para a questão que é ao mesmo tempo completamente satisfatório, aplicável do ponto de vista prático e aceitável do ponto de vista filosófico.
