Pressupostos ontológicos para se pensar a nova tecnologia: técnica, informação e ser e tempo

La recherche presentée, realisée sur le domaine de la méthaphysique, s´agit de rassembler des pressupositions pour une fondamentation ontologique de la technologie de l´Information, basé sur la philophie de Martin Heidegger; foncièrement, sur l´analytique existentiel du Dasein dans l´ouvrage Être et Temps. À partir de la pensée sur ce qui est aujourd´hui , il s´agit d´investiguer sur quels fondaments la Nouvelle Tecnologie se fut érigée de façon a que nous sommes engajés au projet de numérisation des étants que en même temps que destine l´homme a l´oubli de l´Être, l´offre la possibilité de transformation. Le rapport entre la question de l´Être et la question de la technique est analysé comme des chemins croisés et dans ce carrefour il devient possible penser ce qui est technique, ce qui est information pour Heidegger et de quel façon les modes existentiels du Dasein sont prêtes pour caractériser l ´homme au sein de la tecnologie de l´information. Par cette appropriation, il reste penser comment c´est possible l´ouverture d´une perspective de reconduction de l´homme à la vérité de l´Être. Finalement, la structuration des fondements rends possible la réflexion discursive général: avec qui nous nous ocuppons, comme nous sommes, dans quelle direction nous nous acheminons, les thèmes générales, respectivement, des trois chapitres. Les points d´investigation du premier chapitre son: a) La caractérisation précise du Dasein, appuyé sur des considerations de Benedito Nunes, Hans-Georg Gadamer, Jacques Derrida et Rüdiger Safränski; b) Le concept de technique et son essence chez Heidegger; c) la distinction entre technique et technologie, appuyé sur le pensée de J. Ellul, Michel Séris, Otto Pöggeler, Michel Haar, Dominique Janicaud; c) Le concept de cibernetique chez Heidegger et chez Norbert Wiener; d) La caractérisation preliminaire d´information, l´analyse étimologique e philosophique, l´avis de Heidegger te les théories de Rafael Capurro; f) L´Analyse du phénomène de la numérisation des étants, des considérations de Virilio, et l´analyse d´un concept de virtuel avec Henri Bergson et Gilles Deleuze. Dans le deuxième chapitre, l´analyse des existentiels du Dasein vers le sommaire des fondements de base pour la caractérisation de la technologie de l´information comme un problème philosophique. Finalement, aprés avoir presenté les concepts introdutoires que délimitent le questionement, suivi par les indications et pressupositions ontologiques trouvés sur Être et Temps, le troisième chapitre disserte sur le péril, ce qui sauve et la sérénité, les trois mots-clés de la pensée heideggerienne sur la technique que permettent l´approche conclusif de la question

Antecedentes histórico-filosóficos da problemática do tempo e do mal no freiheitsschrift de schelling: aproximações gnósticas

This thesis aims better understanding the relation between time and evil in Schelling s Freiheitsschrift, having its starting point in approximations from Gnosticism. For that purpose, before approaching that relation, it is reviewed (chapter I) the question of Gnosticism, a strain of thought essentially concerned with the problem of time and permeated by the belief in an evil nature of creation, and which is alleged to have significantly influenced certain ideas of Schelling. An evaluation of approximations between Gnosticism, gnosis and German thought follows (chapter II), as well as an evaluation of Schellingian aproximations to Gnosticism (chapter III). Then, the Freiheitsschrift is analysed as the text where Schelling, having taken hold of a very distinct appropriation of Gnosticism, goes beyond Kantian theodicy (chapter IV). Some interrogations about whether key ideas of Schellingian philosophy (about gnosis, creation, duality, time, and evil) are conceived in a way that is essentially different from that of historic Gnosticism, despite the much that has been said to the contrary, are then addressed (chapter V). The proposal of a Platonic-Plotinian key to the understanding of the relations between time and evil in the Freiheitsschrift comes next (chapter VI), and then gives way to the concluding remarks (chapter VII). We perceive that Gnosticism and Neoplatonism are systems of thought that sometimes converge, and that German thought is one of the places of this convergence. Notwithstanding this perception, it is possible to affirm that Schellingian thought, with its valorization of time and of a certain perception of evil, is essentially anti-gnostic, despite some contrary observations

A inferência causal na filosofia moral de Hume.

Starting from the idea that the result of the Humean analysis of causal inferences must be applied coherently to the remaining part of his work, including its moral theory, the present master thesis aims at investigating whether Hume´s moral philosophy is essentially based on feeling, or whether this would not be rather essentially a consequence of our causal inferences in human actions and deliberations. The main idea consists in showing that our moral inferences, to the extent that they are for Hume empirical , depend on our belief in a connexion between something which has been previously observed and something which is not being observed ( but that it is expected to occur or to be observed in the future). Thus, this very belief must base our moral inferences concerning the actions and deliberations of the individuals. Therefore, must e o ipso induce us to associate actions and behaviors, as well as character and moral claims of men to certain moral feelings. Accordingly, the thesis is unfolded in three chapters. In the first chapter Hume´s theory of the perception is reported as essential part of the explanation or the principles that bind ideas in our mind and constitute our inferences. In the second chapter, the Humean analysis of causal inferences is presented and the way they contribute in the formation of our moral inferences is explained. In the third and last chapter, the formation of our moral inferences and the real contribution of the doctrine of freedom and necessity for the examination or our actions are analysed and discussed.

Hermenêutica existencial em Agostinho de Hipona e Martin Heidegger

The thesis presents interpretations of Augustine of Hippo with regard to the first three chapters of genesis, the first book of the Bible. These interpretation are found in the works Literal Commentary on Genesis, concerning Genesis Against the Manicheans, Literal Commentary on Genesis, Unfinished, Books Xi-XIII of the Confessions, as well a brief exposition in Books XI-XIV of the City of God. Exposition of these Augustinian Commentaries seeks to demonstrate various interpretations made by author in one group of texts revealing a hermeneutics centered in the interpreter and not in established interpretive rules. In sequence there is described succinctly the evolution of textual hermeneutics during the modern period up to the reflections conducted by Martin Heidegger in the first half of the twenties. Based in Heidegger s existential commentaries on the Pauline Epistles (Galatians and I-II Thessalonians) and on the tenth Book of the Confessions, there is shown a return to a interpreter-based hermeneutics, such as practiced by Augustine. The concern manifested by Heidegger with regard to given bases foundations, existent in Dasein, foundations which can influence self-comprehension, constitute themselves in possibilities of explication as much for Augustinian interpretive variations, as for the existential approach applied by Heidegger to the Pauline epistles and Augustine s text

Conveniência e plausibilidade da proposição de que justiça é harmonia n A República de Platão

This thesis endorses the interpretation that in Plato`s Republic the argument made by Thrasymachus in which justice is the convenience of the most powerful one is implicitly accepted by Socrates. Although Thrasymachus´ discussion does not show any similarity with the argument of Socrates, it proposes a sarcastic and ironic comment on political life. Socrates accepts this comment to develop a more refined notion of the category of the most powerful ones. While Thrasymachus assumes that the convenience of the most powerful ones includes the power to subordinate all and everything to their individual pleasures, Socrates admits that the most powerful ones are defined only by their characteristic of being able to hold power in perpetuity. In this context, the main theme of The Republic is that the harmony between the functional classes of the city is convenient for perpetual power. For preservation of harmony, the functional class of the most powerful considers the convenience of forsaking a possible monopoly on pleasure towards a redistribution that promotes harmony, which also makes it convenient for the other classes. Thus, we can explicitly say that the most powerful ones believe in a sense of justice as convenience for everyone, but implicitly believe only in the argument that justice is what is convenient for themselves. Since convenience is what promotes harmony between functional classes, it becomes convenient to Socrates to believe that the understanding justice that the most powerful ones have is not publicly disclosed. The notion that all the speculation of the dialogue between the characters cannot be true, but, at best, only plausible and convenient is also part of the central argument in The Republic. Socrates needs to modify the nature of the functional classes through a targeted program of sexual reproduction and a program of ideological indoctrination so that the proposal to promote harmony through the elements of the city, declaring that justice is in favor of the weakest becomes a more plausible and convenient speech. To make the new system more plausible, Socrates develops a metaphysics based on the mathematical notion of harmony, such metaphysics serving the official rhetoric of the political regime presented by Socrates

Elementos da ética sexual Tomista

This dissertation aims to present a elementar vision of thomistic thought about human sexuality from knowledges of vices and virtues. Introduce the notion of vice as otherwise to human nature and seek its etymological meaning, approaching with the neotestamentary perspective of sin and malice. This notion is based in aristotelian and augustinian notion, used by Thomas Aquinas. Also present two virtues inside of the christian thought about the sexuality. They are temperance and chastity. The temperance is a virtue that orders the pleasures of tact, and regulates the chastity. Finally, we show that is possible in thomistic thought admit the legitimacy of sexual pleasure and also the natural necessity in relations, and this relations just can be designed inside of legitimate marriage

O Mitsein e as perspectivas decisórias da autenticidade segundo a analítica existencial: ponderações ontológicas para além dos limites éticos e políticos do ser-com

The present work focuses in the question of being-wit-others (Mitsein) on Martin Heidegger s philosophy. To do so, it takes base on his pivotal scripts, such as Being and Time and Na Introduction to Philosophy, in which this theme is scrutinized. The development line adopted in this work consists in advancing the existential connection between the being-with-others question attained to Dasein s ontological relation in its terms of authenticity and inauthenticity. So on, it is necessary to comment é others philosophical elements that surround this alterity relationship, analyzing phenomenologically how being-in-the-world inflicts the Dasein in its deepest and more important choice aspects, which can direct Dasein to its authenticity or inauthenticity. Facing this decisory context, also shall be observed the way Dasein finds to share the truth in accordance with its interaction with others, and how this mode of being summarizes all ontological structure of man s comprehension. The truth works as an integrative element from which the Dasein cannot escape, being-with-others is an existential situation that Dasein is not able to stop itself from living (its life-in-progress). This work also contemplates the apparent contradiction of Dasein s been always unfolded in The They mode of being, in its everydayness and being like that interacting with others. As along as this question is developed, the work explains how it is possible to be authentic and resolute (as much as inauthentic) as the Dasein interscts with others, even though, there is no pre-defined rule for these ways of relationship between the Dasein and the others

O princípio metafísico da poética de Aristóteles

Aristotle's definition of tragedy indicates a metaphysical project insinuated by a notion of kátharsis. The reconstruction of Aristotle's method of definition is inspired in the concepts of enérgeia and dýnamis taken from Physics, understanding cause as substance. The Doctrine of the Four Causes is the theoretical basis of the definition of tragedy, placing tragedy in the genre of imitation and distinguishing its species: language (material cause), noble and complete action (formal cause), actors (efficient cause) and kátharsis (temporarily identified with the final cause). Nevertheless, there is no final cause in the definition of tragedy. The kátharsis of passions is experienced by the spectator when he witnesses tragedy, which is the imitation of a noble action, executed by actors and not narrated. Aristotle justifies hid proposition in favor of mimesis by assuming that imitation is natural to man since infancy and the view of objects allows whoever contemplates them to identify and learn the originals. As a metaphysical principle, kátharsis is projected to beyond definition of tragedy, where it is manifested cathartically, in the spectator. Research about the spectator brings one back to the definition of tragedy, where the imitation is an imperfect copy which evokes in the spectator the presence of the originals of the imitated sentiments, thus realizing the kátharsis of these emotions. In this way kátharsis reveals itself as selfknowledge and approach of divine truth and perfections.

O conceito de consciência em o ser e o nada de J.-P. Sartre

This current discourse intends to prove how consciousness or Being-for-itself presents the idea that in its operation one can emphasize that it s Nothingness, transience and liberty in Jean-Paul Sartre s work O Ser e o Nada. To testify the proposed idea, the conception that Sartre gives to consciousness, representing nothingness, without any content that is connected to the possessor objects of a transphenomenal existence will be the starting point. This way, consciousness will be analyzed transcendently to the object that it s not, demonstrating its revealer-revealed condition, because it unveils a concrete world that exists against its idea, functioning as the revealer intentionality that there are beings instead of nothingness, obeying the ontological proof defended by Sartre. From this idea, every kind of consciousness will always be consciousness of something, a glance of the world, avoiding the fact that the consciousness could be considered nothing in the world. In order to live its original negation state of the world, apprehending this same world, with the purpose of a knowledge, it needs to be divided in two: the first degree consciousness or previous-reflexive cogito, that turns the proper reflexion possible, because, it s the consciousness proper transphenomenality of being different of all that connected to its existence being only its consequence; and the cogito, responsible to the positioning of the first degree consciousness, while aware of its own consciousness, that is, while being certain that knows. From this point, the way to untangle the consciousness or Being-for-itself will be developed as being Chasm, Liberty and transience. From this idea, it s intended to know how consciousness, that in Sartre s thoughts is originally nothing, could turn into Liberty that is presented in the field of transience? In other words, how these three internal structures imbricate one another to form consciousness in Sartre? First of all, it has to be considered the review of a conduct of human reality, the inquiry, that will be possible to understand how Nothingness exists as the mold of all kind of negation. After this, it will be shown, considering its way of existence, the human reality that is connected to Para-si, determined like nothingness, still is proposed like Liberty. Form this point, it will be possible to gleam how Liberty is lived deeply by Para-si in the shape of chasm, trying to how Para-si turns into nothingness, creating a chasm based on its proper liberty. Then, Liberty will be the proper mechanism used by Para-si to modificate its original chasm. The way Being-for-itself has to build to gain its goal will be projecting in transience, the building of something possible that brings one being back. However, will be demonstrated like Chasm can occupy the moment of a choice turning the decision instant an anguish stage, based on the failing of stability of the Being-for-itself, once nothingness persists in the field of the possibilities that human beings preserves in its essence while being essentially Liberty. From this idea, anguish will be studied as the proper consciousness of Liberty, being bad-faith the attempt of avoid Liberty trying to gain a shelter contradicting the fact that life is done of continual choices

Crítica ao fundacionismo cartesiano com base no argumento contra a linguagem privada

This assignment ains to prove the pertinency of using the wittgenstein´s argument against private language as a criticism to cartesian fundacionism. Therefore, I want to demonstrate in the first chaper the conceptual viability of facing the cartesian argument of cogito not as a simple silogism but as an exemple of a private experience (process of thinking). At the second chaper, the subordination of the argument against private language give us the idea that rules can only be followed by means of corrections givem by a linguistic community that is external to the private subject, in a way to be unviable the assumption that is possible to name an internal experience without searching external rules of the use of terms. At the chaper 3 the pertinency of the hypothesis raised by A. Kenny, about the overtaking of the argument against private language can be extended to the idea of epistemic and ontologic privacy that would lend validity to the fundacion present at the argument at the cartesian cogito. In oder to become evident the pertinency of use of Wittgenstein´s argument agaist Descartes´ fundation, it´s necessary, at the chaper 3, to demonstrate the impertinency of the objection to the A. Kenny´s hypothesis, based on the experiency of the thought of the brain at the recipient, to make clear the incompatibility existing between the cartesian idea of cogito and Wittgenstein´s notion that language is an activitie followed by rules, wich correction criterion may be external and intersubjective

THE EFFECT OF TUBEROINFUNDIBULAR DOPAMINERGIC-NEURONS ON PROLACTIN AND ALPHA-MELANOCYTE STIMULATING HORMONE-RELEASE

The effect of tubero-infundibular dopaminergic neurons (TIDA) on the release of prolactin (PRL) and alpha-melanocyte stimulating hormone (alpha-MSH) was studied in median eminence-lesioned (MEL) male rats (N = 6-28). Plasma PRL and alpha-MSH levels were significantly elevated 2 (86.1 +/- 19.8 and 505.1 +/- 19.1 ng/ml), 4 (278.7 +/- 15.5 and 487.4 +/- 125.1 ng/ml), 7 (116.2 +/- 16.2 and 495.8 +/- 62.6 ng/ml) and 14 (247.3 +/- 26.1 and 448.4 +/- 63.8 ng/ml) days after MEL when compared to sham-operated control animals (55.5 +/- 13.4 and 56.2 +/- 6.1 ng/ml, respectively). MEL altered plasma PRL and alpha-MSH levels in a differential manner, with a 1.5-to 5.0-fold increase in PRL and an 8.0-to 9.0-fold increase in alpha-MSH. The increase of alpha-MSH levels occurred abruptly and remained constant from days 2 to 14. These observations indicate that TIDA plays an important role in the pituitary release of PRL and alpha-MSH and provide evidence that the release of the two hormones occurs in a differential manner.

Effects of unilateral decortication on β-adrenergic receptors in the remaining cortex and in the hypothalamus of female rats

Many experiments have been performed to evaluate the physiological role of catecholaminergic mechanisms of gonadotropin release. The purpose of the present study was to determine the concentration of β-adrenoreceptors in the remaining (right) cerebral cortex and in right and left hypothalamic halves of hemi-decorticated female rats which exhibited elevated plasma gonadotropin levels as observed previously. The density of β-receptors was measured using a high-affinity β-adrenergic ligand, iodocyanopindolol (ICYP). Scatchard estimates were obtained for maximum binding (B(max) fmol/mg of tissues) from pooled cerebral cortical and hypothalamic tissue of animals under several experimental conditions after hemi-decortication and sham operation. There was an increase in β-adrenoreceptor density in the remaining (right) cerebral cortex at all times examined in hemi-decorticate in comparison with the sham-operated animals (7 days, +10.9%; 21 days, +8.4%; 90 days, +22%; and 90 days plus ovariectomy, +34.8%). The number of β-adrenoreceptors in the right hypothalamic half in hemi-decorticates decreased at 21 days (-42.20%) and then increased at 90 days (+76.63%) and 90 days plus ovariectomy (+51.75%) when compared with the left hypothalamic half. At the same time there were no significant changes in the sham-operated animals when comparing the receptor density in the right and left hypothalamic halves, respectively. Thus, our results suggest a direct adrenergic pathway by which the left cortex can influence the right cortex and a crossed pathway to the contralateral hypothalamus changing adrenergic activity which can alter the β-adrenergic receptor binding capacity in the hypothalamus.
