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

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

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

Confinement of spinless particles by Coulomb potentials in two-dimensional space-time

The problem of confinement of spinless particles in 1 + 1 dimensions is approached with a linear potential by considering a mixing of Lorentz vector and scalar couplings. Analytical bound-states solutions are obtained when the scalar coupling is of sufficient intensity compared to the vector coupling. (c) 2005 Elsevier B.V. All rights reserved.

Reflexões sobre a formação clínica fenomenológico-existencial na era da técnica

Phenomenology is the focus of this study for its critique of the limits of positivist science, which guides most of the fields of study including Psychology. The clinical formation process in Psychology courses is especially difficult for students-interns who adopt phenomenology as their clinical framework. Such difficulty is due to the incompatibility between theory provided in Psychology courses a science traditionally based on paradigms of scientism , and the theoretical-methodological proposal adopted by the aforementioned approach. As a backdrop for our study, we carefully examined the thought of philosopher Martin Heidegger, especially the Era of Technique. This contemporary technicism society was studied so that we could understand the socio-cultural status where this formation lies. Thus, we questioned if this panorama upon which Clinical Psychology rests favors the development of a phenomenological attitude and a special look at the meanings of existence, as defined in phenomenological clinical practice. Knowing such limits, our research aimed at understanding the experience of formation of clinical psychologists who take part in internships in the field of phenomenology-existentialism. Such study was, then, a phenomenological-hermeneutic research based on Heideggerian ontology and used a semi-structured interview as access tool. Six students of the UFRN higher-degree Psychology course who were doing their supervised internship in clinical psychology and the referred approach took part in this research. The research revealed that the phenomenological-existential formation phase opens a door to discoveries on the part of the intern that transcend the dimension of the other, for they show a self disclosure while a person in the word. Despite the initial discomforts caused by the course curriculum itself and by the freedom for clinical practice, so characteristic of phenomenology, the narratives demonstrate that such difficulties may start a process of search for new meanings, which show a search for sharpening their practices and for a path in balance with the existence of the other

O médico diante da morte na urgência e emergência:reflexões sobre o ser médico

The literature pointed that the way which people deal with death have been changing along centuries, and nowadays what is realized it is that, each time more, the human being have difficulties to deal with death. Due to the fact that the main function of the physician is to save their patients lives; responsibility that is aggravated by the necessity of to take decisions quickly, once he need to deal with the unexpected situations of the urgency and emergency, many times these professional have to face of impotency and fail situations, when he lose a patient. The main goal of this study was to understand the experience of physicians that work in the urgency and emergency, in front of death. These questioning it justified by the fact of the physicians do not have, many times, a space to express their suffering and anguish about the issues related to death in their work routine, despite lifedeath question to be often present their everyday. It is still possible to verify in the literature, an appointment of the necessity of to include in the curriculum of Medicine courses, subjects that approach such questions. The method used was based on the existential-phenomenological perspective, using as instrument the participant observation, to the intent of understand the routine in the urgency and emergency context, and semi-structured interview. It was interviewed six physicians that work in the urgency and emergency of the most important hospital of public health system of Natal-RN. The results showed that the physicians reported pleasure in work in the urgency and emergency, despite of they presented stress and the difficulties that they deal with in the public system. Despite of the fact that the death to be considered as a phenomenon that make part of the physician s routine, sometimes, deals with these one is more difficult. Many times losses generate an impotency and guilty feeling, as well as questionings about their performance during the attempts to save lives. We verified, from this study, the importance of the existence of some kind of intervention in the emergency, in order to the physicians can elaborate the questions about death and die emerged in their work. We consider yet that this study corroborates and reiterates the discussions concerning the importance of this thematic to be approached in a more effective way, during the academic formation of these professionals, as well as, the importance of a larger investment from the part of Government in the urgency and emergency sector, in order to propitiate to these professionals a work that brings less harmful for their health

A new method for real time computation of power quality indices based on instantaneous space phasors

One of the important issues about using renewable energy is the integration of dispersed generation in the distribution networks. Previous experience has shown that the integration of dispersed generation can improve voltage profile in the network, decrease loss, etc. but can create safety and technical problems as well. This work report the application of the instantaneous space phasors and the instantaneous complex power in observing performances of the distribution networks with dispersed generators in steady state. New IEEE apparent power definition, the so-called Buchholz-Goodhue effective apparent power, as well as new proposed power quality (oscillation) index in the three-phase distribution systems with unbalanced loads and dispersed generators, are applied. Results obtained from several case studies using IEEE 34 nodes test network are presented and discussed. (C) 2006 Elsevier B.V. All rights reserved.

Experiências maternas de perda de um filho com câncer infantil: uma compreensão fenomenológico-existencial

Death due to childhood cancer reflects an early outcome of life, which can cause a strong repercussion in the mother s existence - figure to whom the greatest part of responsibilities during the child s illness is commonly allocated. The aim of this study is to understand the experience of mothers who have lost a kid as a consequence of childhood cancer, approaching the personal senses of this fact. Following a qualitative research design, with an exploratory and comprehensive approach, the study used the narrative method, which was obtained from a semi-structured interview, as the data generation procedure. The research counted on the participation of three adult mothers who had lost their kids because of childhood cancer, after - at least - a six-month period of oncologic treatment. The proposal of analysis follows the parameters of the phenomenological method and the data are based on Martin Heidegger s existential analytic. The results were structured into three thematic axes: previous History, child illness and its repercussions; The network of support and care; Loss and after loss: facing and signifying. It was possible to comprehend that the emergence of cancer in childhood promotes, since the diagnosis, a disruption of everyday meanings, accentuating the fragile condition of human life. In this specific circumstance of childhood illness, all the participants restricted their possibilities of being-in-the-world, dedicating exclusively to the practice of maternity. Concerning their relationship with their children in treatment, the narratives unveiled, in a convergent manner, the existence of care in a substitutive mode. In the network of support - primarily constituted by family, the health team and the support institutions - the relations were marked by proximity and detachment movements. With the child s death, mothers began to live a way of being-with the absent child , ensuring the continuity of the relationship with the dead infant. From the results exposed above, we can understand the motherly mourn as a singular experience in constant resignification, in which the subjective time overlaps the cronological time. The increment of anguish, resulting from the mother s confrontation to the question of finitude, mobilizes a process of change in their way of being-in-the-world, promoting an openness to new possibilities in their lives. Singular attention to the mother, during the process of illness and child loss, turns out to be fundamental
