Le problème de la dualité du corps et de l'intelligence et le rôle de l'art chez Schopenhauer

Hébert, Hélène 17 April 2018 (has links)
Le présent mémoire se veut une analyse des notions de corps et d'intelligence et de leur rapport, dans Le monde comme volonté et comme représentation. Mon argumentation vise à mettre en lumière comment l'assimilation de la volonté à la chose en soi et de la représentation au phénomène conduit Schopenhauer à radicaliser l'opposition entre le corps comme manifestation de la volonté d'une part, et l'intelligence comme capacité à construire le monde comme représentation, d'autre part. La connaissance de l'Être étant le principal objectif de sa philosophie, Schopenhauer explique comment y accéder soit par la voie du sentir pur, soit par la voie au penser pur. Si ces deux voies d'accès à la chose en soi sont diamétralement opposées, elles aboutissent néanmoins, toutes deux, à un dualisme entre le corps et l'intelligence, y compris dans l'art.

Masculinities in Transcultural Spaces / Negotiations of Masculinities in Ang Lee’s Films

Zhang, Yumin 27 March 2018 (has links)
Die vorliegende Arbeit beschäftigt sich mit der Interpretation vier ausgewählter Filme des Filmemachers Ang Lee – Pushing Hands, The Wedding Banquet, Brokeback Mountain und Hulk, die in den Jahren 1992 bis 2005 entstanden. Sie erforscht die unterschiedliche Inszenierung von Konzepten der Männlichkeit im chinesischen und US-amerikanischen Kontext, sowie den Männlichkeitsdiskurs in Räumen des kulturellen Üergangs. Die Untersuchung Lees männlicher Figuren und Männlichkeitskonzepte macht sich sowohl die chinesische als auch die westliche erkenntnistheoretische Perspektive zu eigen, dabei ist Untersuchung sowohl konzeptionell als auch analytisch angelegt. Auf der konzeptionellen Ebene soll sie zeigen, wie sich die Konstruktion von Männlichkeitskonzepten unter der Einbeziehung nicht nur der westlichen konzeptionellen Argumentation von transkulturellen Räumen (Transdifferenz), sondern auch von andersartigen erkenntnistheoretischen Perspektiven, hier der chinesischen, besser erklären lässt. Auf der analytischen Ebene werden in der Untersuchung der Inszenierung männlicher Figuren audio-visuelle Textanalysen benutzt. Die Analyse hat deutlich die Komplexität und Vielfältigkeit der Aushandlung von Männlichkeitskonzepten in transkulturellen Räumen gezeigt, wobei die Rekonstruktion und die Neuverhandlung von Männlichkeit sowohl emanzipatorisch als auch repressiv von statten gehen kann. Männliche Protagonisten bei Lee finden drei unterschiedliche Wege, ihre männliche Identität zu konstruieren. Als erste Lösung unterdrücken sie den transdifferenten Aspekt und wählen die klare Zugehörigkeit zu einer der Kulturen, die dann als Ursprung für die Restauration der Männlichkeit dient. Die zweite Lösung ist das Annehmen der Transdifferenz um eine mehrdeutige maskuline Identität im transkulturellen Raum aufzubauen. Als letzte Lösung gelingt es einen männlichen Figuren, kulturelle Grenzen zu überschreiten und eine transkulturelle Männlichkeit zu manifestieren. / This dissertation consists of readings of four selected films by Ang Lee — Pushing Hands, The Wedding Banquet, Brokeback Mountain and Hulk, ranging over a decade from 1992 to 2005. It explores Lee’s representation of diverse Chinese and American masculinities, discussing negotiations of masculinities in transcultural spaces. My exploration of Lee’s representation of men and masculinities is equipped with double epistemological perspectives, namely, both Chinese and Western. My project is both conceptual and analytical. On the conceptual level, I intend to demonstrate how constructions of masculinities can be more productively explained by employing not only the Western conceptual arguments of transcultural space (transdifference) but also by reading this space from different epistemological perspectives, namely the Western and Chinese. On the analytical level, I employ audio and visual textual analysis in my examination of Lee’s portrayal of male figures. My analysis has clearly demonstrated the complexity and multiplicity in negotiations of masculinities in transcultural spaces, which can be both emancipatory and repressive in re-constructing and re-negotiating one’s masculinity. Male subjectivities in Lee’s films turn to three different ways to construct or reconstruct their manliness. First, men suppress trandifference and opt for a clear belonging to a certain culture, in particular, the culture of origin for masculinity restoration. Second, men embrace transidifference to construct an ambiguous masculine identity in transcultural spaces. Third, men might transcend cultural boundaries to demonstrate transcultural manhood.

Aspect Perception in Wittgenstein’s Philosophical Development

Liang, Xiaolan 25 February 2025 (has links)
Wittgensteins Begriff des Sehen-als, der üblicherweise mit dem Begriff der Aspektwahrnehmung gleichgesetzt wird, ist als eines der zentralen Anliegen seiner späteren Werke zur Philosophie der Psychologie anerkannt worden. Die vorliegende Dissertation untersucht die Entwicklung von Wittgensteins Ideen zur Aspektwahrnehmung und zum Sehen-als, indem sie deren Entwicklung von der frühen Periode, die durch den Tractatus repräsentiert wird, über die mittlere Periode, die durch die Philosophische Grammatik und das Braune Buch repräsentiert wird, bis hin zu den späteren Werken nachzeichnet. Um diese Ziele zu erreichen, folgt meine Arbeit der Abfolge seiner philosophischen Entwicklung. Auf jeder Entwicklungsstufe befasse ich mich zunächst mit dem relevanten Inhalt des Sehens-als, indem ich ihre Rolle in Wittgensteins Werk identifiziere. Dann setze ich mich mit den Argumenten von Wissenschaftlern auseinander, die sich in dieser Zeit für das Sehen-als interessierten, und biete mein eigenes Verständnis an, das auf Wittgensteins Schriften aufbaut, wobei ich meine spezifischen Argumente mit den allgemeinen Zielen verbinde. Schließlich lasse ich den Veränderung und die Kontinuität der Aspektwahrnehmung sich in der Entwicklung von Wittgensteins Ideen zeigen. Es zeigt sich, dass trotz der unterschiedlichen Rollen des Sehen-als auf jeder Stufe, die Kernkonzepte des Sehen-als lebendig bleiben, obwohl in verschiedenen Formen. Diese Zugänge bedeuten, dass ich nicht nur versuche, das noch nicht erforschte Gesamtbild von Wittgensteins Untersuchungen über das Sehen-als darzustellen, sondern auch seine Philosophie im Licht des Sehens-als zu sehen. / Wittgenstein’s notion of seeing-as, usually used interchangeably with aspect perception, has been recognized as one of central concerns in his later works on the philosophy of psychology. While there have been numerous studies into the interest that Wittgenstein took in aspect perception, there have been very few attempts to trace its development in detail. This dissertation is an investigation into the evolution of Wittgenstein’s ideas on aspect perception and seeing-as, tracing their development from the earlier period, represented by the Tractatus, through the middle period, represented by the Philosophical Grammar and the Brown Book, to the later works. In order to achieve these goals, my presentation follows the sequence of his philosophical evolution. At each evolutionary stage, I first deal with the relevant content of seeing-as by identifying their role in Wittgenstein’s work. Then I engage with the arguments made by scholars interested in seeing-as during that period and offer my own understanding building on Wittgenstein’s writings, while connecting my specific arguments to the overall objectives. Finally, I let the change and continuity of aspect perception shows themselves in the development of Wittgenstein’s ideas. It shows that despite the varying roles of seeing-as in each stage, the core concepts of seeing-as remain vivid, though in different forms. These approaches mean that I seek not only to present the still-understudied complete picture of Wittgenstein’s investigations of seeing-as, but also to see his philosophy in the light of seeing-as.

Suscetibilidade diferencial de biótipos de Conyza sumatrensis ao herbicida chlorimuron-ethyl e resistência ao herbicida glyphosate / Differential susceptibility of biotypes of Conyza sumatrensis to the herbicide chlorimuron-ethyl and glyphosate resistance

Santos, Fernando Machado dos 05 December 2013 (has links)
A buva (Conyza spp.) é uma planta daninha anual, comum em lavouras de soja da região Sul do Brasil, onde os herbicidas chlorimuron-ethyl e glyphosate são os mais utilizados para o seu controle. No entanto, nas últimas safras de soja observou-se controle insatisfatório desta planta daninha com esses herbicidas. Esse fato gerou a suspeita de seleção de biótipos resistentes. Assim, o objetivo da pesquisa foi avaliar a ocorrência de resistência múltipla aos herbicidas chlorimuron-ethyl e glyphosate em biótipos de buva. Na primeira etapa do trabalho, foram feitas coletas de sementes de buva em áreas com controle insatisfatório, totalizando 25 biótipos. Esses biótipos foram avaliados com relação à suscetibilidade e resistência ao chlorimuron e glyphosate, aplicando-se a máxima dose de registro desses herbicidas. Para segunda etapa do trabalho, foram selecionados 5 biótipos de buva com grau de suscetibilidade contrastante. Esses biótipos foram avaliados com curvas de dose-resposta e com 5 doses do herbicida chlorimuron-ethyl, aplicadas no estádio fenológico de 3 a 4 folhas. Na terceira etapa do trabalho, foi avaliada a resposta de 4 biótipos de buva aos herbicidas chlorimuron-ethyl, glyphosate e associação de chlorimuron-ethyl e glyphosate. Os herbicidas foram empregados em oito doses: 0,0; 6,25; 12,5; 25; 50; 100; 200 e 400, representadas em porcentagem da dose de 20 g ha-1 chlorimuron-ethyl, e de 720 g e.a. ha-1 glyphosate, aplicadas em três estádios de desenvolvimento (altura 0,5 a 1 cm e/ou 3 a 4 folhas; altura 1 a 2 cm e/ou 6 a 7 folhas e; altura 10 a 12 cm e/ou 12 a 14 folhas) dos biótipos de buva. Na última etapa do trabalho, avaliaram-se 15 herbicidas para controle alternativo da buva no estádio de desenvolvimento de 5 a 7 cm de altura e/ou 7 a 8 folhas. O trabalho foi conduzido na casa de vegetação, da Estação Experimental da Embrapa Trigo, em Passo Fundo/RS. Os resultados evidenciam que todos os biótipos são controlados com a dose de 20 g ha-1 de chlorimuronethyl, no estádio de desenvolvimento de 3 a 4 folhas. Contudo, observou-se susceptibilidade diferencial entre os biótipos em doses menores que 20 g ha-1 indicando resistência de nível baixo. Também, ficou evidente que os estádios de desenvolvimento dos biótipos de buva afetam significativamente a resposta destes aos herbicidas, sendo que quanto mais avançado o estádio menor a sensibilidade. A exceção foi o biótipo 5 que demonstrou resistência ao glyphosate, independentemente do estádio de desenvolvimento. Por fim, os tratamentos alternativos 2,4-D (1.042 g ha-1); amonium glufosinate (400 g ha-1); glyphosate (900 g e.a. ha- 1) + 2,4-D (1.042 g ha-1); glyphosate (900 g e.a ha-1) + amonium glufosinate (400 g ha-1); paraquat (600 g ha-1) + diuron (300 g ha-1); tembotrione (84 g ha-1) e tembotrione (84 g ha-1) + atrazine (1.000 g ha-1) controlaram, eficientemente, os biótipos de buva avaliados. Como conclusão, indica-se a aplicação do herbicida chlorimuron-ethyl nas doses máximas registradas, em estádios de desenvolvimentos da buva inferiores a cinco folhas, e que a prática de rotação de mecanismos de ação seja usada no manejo químico dessas áreas. / The horseweed (Conyza spp.) is an annual weed, common in soybean crops in southern Brazil, where the herbicide chlorimuron-ethyl and glyphosate are the most commonly used for its control. However, in recent soybean harvests it was observed unsatisfactory control of this weed with these herbicides. This fact originated suspicion of selection of resistant biotypes. The objective of the research was to evaluate the occurrence of multiple resistances to herbicides chlorimuron-ethyl and glyphosate in horseweed biotypes. In the first stage of the research, were collected horseweed seeds in areas with unsatisfactory control, totaling 25 biotypes. These biotypes were assessed for susceptibility and resistance to chlorimuron and glyphosate, applying the maximum dose of herbicide registration. In the second stage, were selected 5 horseweed biotypes with contrasting degree of susceptibility and evaluated dose-response curves, with 5 doses of the herbicide chlorimuron-ethyl applied at growth stage 3 - 4 leaves. In the third stage, we evaluated the response of four biotypes of horseweed to the herbicide chlorimuron-ethyl, glyphosate and association of chlorimuronethyl and glyphosate. Herbicides were applied in eight doses: 0.0, 6.25, 12.5, 25, 50, 100, 200 and 400, represented as a percentage of the dose of 20 g ha-1 chlorimuron-ethyl, and 720 g a.e. ha-1 glyphosate applied at three stages of development (height 0.5 - 1 cm and / or 3 - 4 leaves, height 1 - 2 cm, and / or 6 - 7 and leaves, height 10 - 12 cm and / or 12 - 14 leaves) biotypes of horseweed. In the last stage of the study, evaluated 15 alternative herbicides to control horseweed at stage 5 - 7 cm high and / or 7 - 8 leaves. The study was conducted in a greenhouse, at the Experimental Station of Embrapa Trigo, Passo Fundo / RS. The results show that all biotypes can be controlled with the dose of 20 g ha-1 chlorimuron-ethyl, at stage 3 - 4 leaves. However, it was observed differential susceptibility among biotypes at doses under than 20 g ha-1 indicating low resistance. It was also evident that the developmental stages of the biotypes of horseweed, significantly affect the response to these herbicides, whereas the more advanced the stage the lower sensitivity. The exception was the biotype 5 that show resistance to glyphosate, regardless of the stage of development. Finally, alternative treatments 2,4-D (1.042 g ha-1); ammonium glufosinate (400 g ha-1), glyphosate (900 g a.e. ha- 1) + 2,4-D (1.042 g ha-1), glyphosate (900 g a.e. ha-1) + ammonium glufosinate (400 g ha-1), paraquat (600 g ha-1) + diuron (300 g ha-1); tembotrione (84 g ha-1) and tembotrione (84 g ha- 1) + atrazine (1,000 g ha-1), effectively controlled the biotypes of horseweed evaluated. Conclusion indicates the application of herbicide chlorimuron-ethyl in maximum doses recorded in stadiums horseweed developments less than five leaves, and that the practice of rotating mechanisms of action are used in the chemical management of these areas.

Die Steinmetzzeichen an der Frauenkirche zu Dresden und deren Bedeutung

Remus, Torsten 01 March 2005 (has links) (PDF)
Diese Arbeit soll die Rolle der Zeichen am genannten Gebäude untersuchen. Im Verlauf der Analyse sollen drei Funktionen der Zeichen bewiesen werden. Zunächst erfolgt die Ausarbeitung der allgemein bekannten Verwendung der Steinmetzzeichen als "persönliches Zeichen" und "Abrechnungszeichen" am Beispiel der Frauenkirche. Als eigentliches Endergebnis der Arbeit steht die Feststellung der weiteren Nutzung der Steinmetzzeichen als "Versetzzeichen" oder auch "Versetzmarke". Sie können an besonderen Stellen des Gebäudes im engen Zusammenspiel mit zusätzlich in den Stein eingebrachten Steinzeichen auftreten. Solche Markierungen werden als "Zusatzzeichen" benannt. Die sich daraus ableitenden Besonderheiten werden gleichfalls dargestellt. Um sich der betreffenden Fragestellung zu nähern, war eine Erfassung und Dokumentation aller gefundenen Steinzeichen notwendig. Ein Studium des Trümmerberges und des vorangegangenen Einsturzes der Kirche ist als erster Arbeitsschritt erfolgt. In dieser Folge entstand als Ergebnis eine umfangreiche Datenbank. Deren Inhalt wird mit Hilfe verschiedener Grafiken anschaulich gemacht. Die vorgelegte Arbeit kann die aus der bisherigen Diskussion zur allgemeinen Thematik offenen Fragen nicht mit allgemein verbindlichen Antworten abschließen. Sie kann jedoch die Auseinandersetzung bereichern, in dem am Beispiel der Frauenkirche zu Dresden spezifische Besonderheiten des Zeichenwesens aufgezeigt werden.
