O filósofo e o pensamento intempestivo

Ce travail consiste en présenter la façon tel comme l'image du philosophe apparaît dans le penseé de Nietzsche sur sa série Considérations Intempestives où il esquisse un type d'homme proprement philosophique, ainsi comme il présent en détails ce qu'il pense sur la philosophie et son rôle par rapport à son temps, en articulant ces idées de façon intrinsèque avec un sens renouvelé sur la culture, qui joue un rôle important dans l'enseemble de son oeuvre. Sur cette base, nous nous proposons de penser comme une philosophie intempestive se rapporte à l'histoire, en remplaçant au premier plan ce que concerne au philosophe considéré le médicin de la culture. L'objectif ici est alors de penser quel est l'office du philosophe en temps de chaos

Uma nova tecnologia no pensamento de Herbert Marcuse: arte e técnica na sociedade unidimensional

This dissertation addresses the issue of technology in the work of Herbert Marcuse, explaning the merger between technology and domination that result in a totalitarian technological apparatus. Thus, technological civilization is supported and justified by a rational technological apparatus in the society, we have come not only the philosophy of Marcuse, but other great thinkers too, like Heidegger, Hegel, Marx. We also present a debate involving the philosophy of science, logic and linguage. Marcuse points to the need for a new technological rationality that emerge from a new sensibility, where the technique would allow a new relationship between man and nature. From then on, would emerge the need for a new subject. This transition would be possible by means of sensitivity, where art would become the art of live. With the link between art and technique made possible by new sensitivity, the author leaves one of its main contribution: he leaves open the possibility for the subject to choose new targests for technological development

O entardecer de uma era: técnica, poesia e pensamento em Heidegger

The thinking dialog between Heidegger s philosophy and the poetry of Hölderlin and Rilke must be dealt in language s domains. The difficulty to establish this dialog comes from the man in itself, unable to think out of the understructure of science and the modern technique. The poetic language was forgotten or ignored, turning itself obsolete in front of improvements and resources of the technique. Heidegger searches the essences to the poetry so may it be comprehended in its plenitude for the man. Technique, poetry and existence must be pronounced and investigated so the being shows itself again. To Heidegger, the man lives in a period of uncertainty due finding himself at the sunset of age. The uncertainty generates the poverty and the night of world represents the absence of god and original truth. Only with the fundamental comprehension of poetry, the man of today can project himself to the future not anymore as technique product, but with freedom to choose. The message of poetry of Hölderlin and Rilke, according to Heidegger s interpretation, transmits an alert to the contemporary man against the coming danger in his maintained relation with nature. The purpose of the following work is to build this thinking dialog, without disfigure the poetry, but taking approach over its essence, so from there to remove its true existential value.

O corpo no pensamento de Epicuro: limites e possibilidades

The theme that fits the perspective of this thesis comes from the interest of treating, in the Epicurean corpus, about the importance of the body and its manners of realization for understanding the thought of Epicurus of Samos. Based on the inferences contained in the texts that remained from Epicurus, we did an analysis of the aspects that characterize Epicurism as a thought that makes repeated references to the body as an instance of sensitivity. It was necessary, therefore, to discuss how the body is linked to the possibility of thought, and how the latter can be admitted as a body element. It is further understood that the atomistic physics converges to the idea that asserts natural phenomena as likely to be contained and explained by the observations that come from the senses which are manifested through the body. For this reason, it was also pertinent to reflect on the admission of the body as a key element for the interpretation of Epicurean thought, even under the constitution of language. The Epicurean construction about body image was also used for the interpretation and questioning of the dynamics that define the relationships between individuals, characterizing the koinonía of the garden through the notion of corporeal unity. It was defined, therefore, that the characterization of the action field of individuals who lived in the Epicurean garden revolves around the use of logos, with the dialogues coming from the exercise of philosophy for therapeutic purposes, which were able to introduce a specific mode of political action marked by the absence of strange interests of the notion of philía

Sujeito e liberdade no pensamento de Michel Foucault

The leitmotif of this dissertation research is on the relationship between two fields of questioning in the Foucauldian works that may be considered, at a first glance, irreconcilable: the understanding of subject as the result of determinations, on the one hand, and its ethical stance of seeking the creation of liberty, on the other. Since, despite this apparent inconsistency, both ideas are present with much emphasis on the work of the French thinker, to understand the way Foucault articulated these two ideas was necessary to elucidate and interrelate the way in which he thought about the concepts of subject, power and liberty. Traveling with the author his intellectual itinerary, it was revealed that his conception of subject and liberty can be reconciled (although maintaining its problematic nature) and, also, both are inextricably linked each one as a result of the other. Tracing, with the author, his intellectual itinerary, it was also possible to identify and describe the fruitful conceptual tools for thinking about our own determinations and about the possibilities we have of creating new subjectivities and liberating experiences

Reflexões filosóficas em torno da constituição do sujeito religioso-moral no pensamento de Freud

The present research deals with a philosophical reflection about the constitution of the subject religious and moral in the thought of Freud, starting from of question of religion while one of the various spaces concretion of the individual morality. Our hypothesis is that religion presents itself as a space of revival of the primary relationship with the mother of the subject and as a moral agency. That primary relationship corresponds to the period before the Oedipus complex. The cut caused in the Oedipus complex sake in the an emptiness the subject, leading him to a situation of helplessness. In trying to fill the emptiness and consequently out of the situation of displeasure occasioned by the helplessness, the individual seeks diverses means, between which, the religion. The religion, that sense, quest for one part, that support be filling of the existential emptiness, triggered in the Oedipus complex, and on the other, works as a staunch ally of the Superego, which for turn is direct heir of the Oedipus complex and whose function is to require of the subject to moral living, as is established by the social body, where the individual is inserted. Therefore, we seek to draw this subject starting from general ideas of the philosophy, about the moral, as well as some theoretical elements of freudian thought, since his idea of the origin of the culture, morality and religion the more specific elements that pertain to the individual subject, ie, the psychism

A produção do conhecimento científico: relação sujeito-objeto e desenvolvimento do pensamento

O presente estudo coloca em questão a produção do conhecimento científico como uma das expressões da relação sujeito-objeto, analisando-a à luz da teoria materialista histórico-dialética do conhecimento. Com o objetivo de demonstrar que a interação prática do sujeito com o objeto apenas fundamenta a produção do conhecimento científico pela mediação teórica, reiteramos a importância do ensino escolar e da apropriação dos saberes historicamente sistematizados, indicando a unilateralidade presente em concepções que enfatizam demasiadamente a prática em detrimento da teoria.

Civilização, sexualidade e entropia no pensamento de Freud

This article intends to offer, in an introductory way, a reflection in order to build an interpretation of the Sigmund Freud's thought, orchestrating notions such as the ones of progress of civilization, which would be his philosophy of history; an investigation on his conceptions about "human nature"; culminating in a brief reflection on some points of philosophy of nature that underlies his thought. We anticipate that we recognize in the latter, characteristics assimilated by analogy to the entropy concept of modern physics. Among other features, such as compared and methodological reference with some of Kant's theses about the same notions, we also present in a short way two metapsychological aspects of Freudian theory on human sexuality, the biological and physiological, both aiming to give support to the reflections on the sense of finality.

Revisitando o eletrocorticograma intra-operatório na epilepsia mesial do lobo temporal: relevância das oscilações de alta frequência

Epilepsies are neurological disorders characterized by recurrent and spontaneous seizures due to an abnormal electric activity in a brain network. The mesial temporal lobe epilepsy (MTLE) is the most prevalent type of epilepsy in adulthood, and it occurs frequently in association with hippocampal sclerosis. Unfortunately, not all patients benefit from pharmacological treatment (drug-resistant patients), and therefore become candidates for surgery, a procedure of high complexity and cost. Nowadays, the most common surgery is the anterior temporal lobectomy with selective amygdalohippocampectomy, a procedure standardized by anatomical markers. However, part of patients still present seizure after the procedure. Then, to increase the efficiency of this kind of procedure, it is fundamental to know the epileptic human brain in order to create new tools for auxiliary an individualized surgery procedure. The aim of this work was to identify and quantify the occurrence of epilepticform activity -such as interictal spikes (IS) and high frequency oscillations (HFO) - in electrocorticographic (ECoG) signals acutely recorded during the surgery procedure in drug-resistant patients with MTLE. The ECoG recording (32 channels at sample rate of 1 kHz) was performed in the surface of temporal lobe in three moments: without any cortical resection, after anterior temporal lobectomy and after amygdalohippocampectomy (mean duration of each record: 10 min; N = 17 patients; ethic approval #1038/03 in Research Ethic Committee of Federal University of São Paulo). The occurrence of IS and HFO was quantified automatically by MATLAB routines and validated manually. The events rate (number of events/channels) in each recording time was correlated with seizure control outcome. In 8 hours and 40 minutes of record, we identified 36,858 IS and 1.756 HFO. We observed that seizure-free outcome patients had more HFO rate before the resection than non-seizure free, however do not differentiate in relation of frequency, morphology and distribution of IS. The HFO rate in the first record was better than IS rate on prediction of seizure-free patients (IS: AUC = 57%, Sens = 70%, Spec = 71% vs HFO: AUC = 77%, Sens = 100%, Spec = 70%). We observed the same for the difference of the rate of pre and post-resection (IS: AUC = 54%, Sens = 60%, Spec = 71%; vs HFO: AUC = 84%, Sens = 100%, Spec = 80%). In this case, the algorithm identifies all seizure-free patients (N = 7) with two false positives. To conclude, we observed that the IS and HFO can be found in intra-operative ECoG record, despite the anesthesia and the short time of record. The possibility to classify the patients before any cortical resection suggest that ECoG can be important to decide the use of adjuvant pharmacological treatment or to change for tailored resection procedure. The mechanism responsible for this effect is still unknown, thus more studies are necessary to clarify the processes related to it

Pensamento brasileiro e integração regional

O objetivo deste trabalho é analisar a forma como algumas escolas de pensamento, representadas por figuras significativas, percebem no Brasil o tema da integração regional. O foco é a segunda metade do século XX, buscando compreender as concepções de projeção regional e internacional do país, que fundamentam as possibilidades de integração. Para isso, serão discutidos os seguintes temas: o papel do Estado, a visão de país, o nacionalismo, o desenvolvimento econômico e o subdesenvolvimento, o reconhecimento internacional e a percepção dos vizinhos. A ideia da especificidade frente aos países vizinhos é um elemento presente na obra de intelectuais e de formuladores de políticas. Ela se faz presente em muitos países, inclusive em outros dessa região. Buscaremos entender como essa ideia evoluiu no Brasil, chegando, nos anos 1980, à aceitação da existência de uma comunidade de interesses com os países do Cone Sul e da América do Sul.

O uno e o ser no pensamento de Meister Eckhart

O problema de fundo da especulação eckhartiana é a verdade do ser uno enquanto Deus e divino ligada à questão do seu conhecimento. Operando uma síntese da tradição neoplatônico-agostiniana e do pensamento do Pseudo-Dionísio Areopagita, o mestre dominicano funda os alicerces da sua teologia unitiva na teoria do ser.

Eficácia do propofol e da associação de propofol e dexametasona no controle de náusea e vômito no pós-operatório de laparoscopia ginecológica

JUSTIFICATIVA E OBJETIVOS: A laparoscopia ginecológica é procedimento que determina alta incidência de náusea e vômito no pós-operatório. Este estudo teve por finalidade comparar a eficácia do propofol isoladamente ou em associação com a dexametasona na prevenção de náusea e vômito em pacientes submetidas à laparoscopia ginecológica. MÉTODO: Participaram do estudo 40 pacientes, estado físico ASA I e II, com idades entre 18 e 46 anos, sem queixas gástricas prévias, submetidas à laparoscopia para diagnóstico ou cirurgia. As pacientes foram divididas em 2 grupos: o grupo 1 recebeu (solução fisiológica 2 ml) e o grupo 2 dexametasona (8 mg), por via venosa antes da indução da anestesia. Todas as pacientes receberam midazolam (7,5 mg) por via oral como medicação pré-anestésica, sufentanil (0,5 µg.kg-1), propofol em infusão contínua para indução e manutenção da anestesia (BIS - 60) e N2O/O2 em fração inspirada de O2 a 40% e atracúrio (0,5 mg.kg-1) como bloqueador neuromuscular. A analgesia pós-operatória foi realizada com cetoprofeno (100 mg) e buscopam composto ®.As pacientes fora avaliadas na sala de recuperação pós-anestésica (SRPA) e na enfermaria 1, 2, 3 e 12 horas após a alta da SRPA. RESULTADOS: Ambos os grupos foram idênticos quanto aos dados antropométricos e à duração da cirurgia e da anestesia. No grupo 1 (n = 20) uma paciente apresentou náusea na SRPA e na enfermaria e três pacientes vomitaram na enfermaria. No grupo 2 (n = 20) nenhuma paciente apresentou náusea ou vômito durante o período de observação clínica, resultados estatisticamente não significativos. CONCLUSÕES: O propofol isoladamente ou associado à dexametasona foi eficaz na prevenção de náusea e vômito no pós-operatório de pacientes submetidas à laparoscopia ginecológica

Tuberculose ativa em pacientes cirúrgicos com baciloscopia negativa no pré-operatório

OBJETIVO: Verificar a proporção de pacientes com baciloscopia negativa no pré-operatório e que apresentaram TB ativa na peça cirúrgica. MÉTODOS: Estudo retrospectivo de pacientes com diagnóstico histopatológico de TB ativa ou sequelar e operados entre os anos de 2003 e 2006 em um hospital universitário. Foram pesquisados antecedentes e aspectos clínicos relativos à doença, pesquisa de bacilos álcool-ácido resistentes (BAAR), tipo de cirurgia realizada e exame histopatológico da peça cirúrgica. RESULTADOS: Foram incluídos 43 pacientes, com média de idade de 44 ± 19 anos, sendo 27 do sexo masculino. Apresentavam história prévia de TB com tratamento adequado 28 pacientes, e 15 não referiam antecedentes para TB. O principal motivo da procura pelo serviço foi infecção de repetição, seguida por achados em exames de imagem. Dos 43 pacientes, foi pesquisado BAAR no pré-operatório em 35: 32 apresentaram resultados negativos e 3, resultados positivos. Dos 35 pacientes pesquisados, 26 apresentavam diagnóstico histopatológico de TB ativa e 9 de TB sequelar na peça cirúrgica; os outros 8 também foram diagnosticados com TB sequelar. A proporção de TB ativa em doentes com baciloscopia negativa foi de 72% (23/32), e o de baciloscopia negativa em TB ativa foi de 88% (23/26), sendo a pesquisa de BAAR positiva somente em 11,5% (3/26). CONCLUSÕES: A baciloscopia direta tem rendimento muito baixo, e muitos pacientes mesmo já tratados podem permanecer com TB em atividade com baciloscopia negativa. A TB ativa pode ser confundida com infecções secundárias ou com câncer.
