Dickens in the Context of Victorian Culture: an Interpretation of Three of Dickens's Novels from the Viewpoint of Darwinian Nature

Moon, Sangwha 08 1900 (has links)
The worlds of Dickens's novels and of Darwin's science reveal striking similarity in spite of their involvement in different areas. The similarity comes from the fact that they shared the ethos of Victorian society: laissez-faire capitalism. In The Origin of Species, which was published on 1859, Charles Darwin theorizes that nature has evolved through the rules of natural selection, survival of the fittest, and the struggle for existence. Although his conclusion comes from the scientific evidence that was acquired from his five-year voyage, it is clear that Dawinian nature is reflected in cruel Victorian capitalism. Three novels of Charles Dickens which were published around 1859, Bleak House, Hard Times, and Our Mutual Friend, share Darwinian aspects in their fictional worlds. In Bleak House, the central image, the Court of Chancery as the background of the novel, resembles Darwinian nature which is anti-Platonic in essence. The characters in Hard Times are divided into two groups: the winners and the losers in the arena of survival. The winners survive in Coketown, and the losers disappear from the city. The rules controlling the fates of Coketown people are the same as the rules of Darwinian nature. Our Mutual Friend can be interpreted as a matter of money. In the novel, everything is connected with money, and the relationship among people is predation to get money. Money is the central metaphor of the novel and around the money, the characters kill and are killed like the nature of Darwin in which animals kill each other. When a dominant ideology of a particular period permeates ingredients of the society, nobody can escape the controlling power of the ideology. Darwin and Dickens, although they worked in different areas, give evidence that their works are products of the ethos of Victorian England.

Effects of multi-scale rainfall variability on flood frequency : a comparative study of catchments in Perth, Newcastle and Darwin, Australia

Samuel, Jos Martinus January 2008 (has links)
Issues arising from climate change and long-term natural climate variability have become the focus of much recent research. In this study, we specifically explore the impacts of long-term climate variability and climate changes upon flood frequencies. The analyses of the flood frequencies are carried out in a comparative manner in catchments located in semiarid-temperate and tropical landscapes in Australia, namely Perth, Newcastle and Darwin, using a process-based derived flood frequency approach. The derived flood frequency analyses are carried out using deterministic rainfall-runoff models that capture the intrinsic water balance variability in the study catchments, and driven by temporal rainfall event sequences that are generated by a stochastic rainfall model that incorporates temporal variabilities over a multiplicity of time scales, ranging from within-event, between-event to seasonal, multi-annual and multi-decadal time scales. Six climate scenarios are considered for Newcastle, that combine the ENSO (El Niño Southern Oscillation) and IPO (Inter-decadal Pacific Oscillation) modes of variability, and six different climate scenarios are considered for Perth and Darwin that combine these different ENSO modes and step changes in climate (upwards or downwards) that occurred in 1970 in both regions, which were identified through statistical analysis. The results of the analyses showed that La Niña years cause higher annual maximum floods compared to El Niño and Neutral years in all three catchments. The impact of ENSO on annual maximum floods in the Newcastle catchment is enhanced when the IPO is negative and for Perth, the impact of ENSO weakens in the post-1970 period, while it strengthens in Darwin in the same period. In addition, the results of sensitivity and scenario analyses with the derived flood frequency model explored the change of dominant runoff generation processes contributing to floods in each of the study catchments. These analyses highlighted a switch from subsurface stormflow to saturation excess runoff with a change of return period, which was much more pronounced in Perth and Darwin, and not so in Newcastle. In Perth and Darwin this switch was caused by the interactions between the out-of-phase seasonal variabilities of rainfall and potential evaporation, whereas the seasonality was much weaker in Newcastle. On the other hand, the combination of higher rainfall intensities and shallower soil depths led to saturation excess runoff being the dominant mechanism in Newcastle across the full range of return periods. Consequently, within-storm rainfall intensity patterns were important in Newcastle in all major flood producing events (all return periods), where they were only important in Perth and Darwin for floods of high return periods, which occur during wet months in wet years, when saturation excess runoff was the dominant mechanism. Additionally, due to the possibility of a change of process from subsurface stormflow to saturation excess when conditions suited this switch, the estimates of flood frequency are highly uncertain especially at high return periods (in Darwin and Perth) and much less in Newcastle (when no process change was involved).

Mellan ideal och vetenskap: bild-textdissonanser i framställningar av djur i Svenska Familj-Journalen 1877–1882

Andrén, Sara January 2023 (has links)
This thesis examines the Swedish 19th century family magazine, Svenska Familj-Journalen, and the interaction between bourgeois attitudes, science, and depictions of animals. My main purpose is to demonstrate how image-text divergences can discover ruptures between 19th century bourgeoise ideology and science. The study consists of a selection of illustrations and texts, the majority being popular zoology depictions that were published in the magazine between 1877–1882. By using nature-culture oppositions as well as art historian Sonya Petersson’s concept of the counteractive illustration, I am able to elucidate differences between texts and images. The texts and images are subsequently analyzed by relating them to contemporary scientific discourses, as well as to the early Swedish animal welfare and nature conservation movements.  The results of this study are that image-text divergences reveal 1) that images of animals could depict the animal as such, rather than as a symbol of bourgeois ideals, 2) an insecurity in the magazine’s attitudes toward Darwin’s theory of sexual selection, illustrating circumstances where the magazine chose to adhere to its ideological dispositions rather than accept Darwinian consensus, 3) that the magazine, in publishing texts that were critical of wild life exploitation, diverged from its progress oriented narrative, and that its use of images counteracted these messages.

Ingrid Winterbach, 'n derde kultuur en die neo-Victoriaanse romantradisie (1984-2006)

Lemmer, Erika 08 1900 (has links)
This research report explores the link between the novels of Ingrid Winterbach / Lettie Viljoen, a third culture and the neo-Victorian novel. The study is therefore situated within the cultural-philosophical framework of a third culture, which implies that the two cultures of science and literature do not function as separate disciplines, but as an organic unit. Researchers in the interdiscipline of literature and science identify the Age of Science (1879–1914) – including the Victorian era (1837–1901) – as a historical period where the existence of such a third culture was observed. This period was characterised by numerous scientific discoveries, and Darwin’s theory of evolution generated heated debates in Victorian society. Nineteenth-century literature (and specifically the Victorian novel) therefore reflects the spirit of an age where the interaction between science and literature was particularly evident. In our information-driven society, the focus is once again on scientific discovery and dissemination of knowledge, prompting social critics to typify the current period as “neo-” or “retro-Victorian”. The contemporary imagination still problematises Darwin’s theory of evolution, and fiction such as Winterbach’s therefore not only renegotiates the fixed modernistic boundaries between science and literature, but also revisits the nineteenth- century genres simptomatic of a similar third culture. Winterbach’s novels (1984–2006) display a distinctive predisposition towards natural history and Darwinistic principles and are therefore postmodern adaptations of nineteenth-century conventions. Darwinistic concepts such as growth, metamorphosis,transformation, evolution and the origin, naming and extinction of species are therefore accentuated. Winterbach’s fictionalisation of a nineteenth-century worldview can be linked to the work of her ancestors in the Afrikaans literary tradition, Eugène Marais and C. Louis Leipoldt (both amateur scientists). Her popularisation of scientific knowledge and revisitation of Victorian codes also link her to a neo-Victorian novelistic movement (a contemporary permutation of the Victorian tradition). Her oeuvre therefore also displays similarities to that of her British contemporary, A.S. Byatt, a prominent neo-Victorian novelist. An exploration of the natural world in this tradition, however, also implies an exploration of supernatural spheres, a trend which is equally evident in texts by congeners such as (George) Eliot, Marais, Leipoldt, Winterbach and Byatt. / Afrikaans / D.Litt. et Phil.

Contemporary poets' responses to science

MacKenzie, Victoria R. January 2013 (has links)
This thesis considers a range of contemporary poets' responses to science, emphasising the diversity of these engagements and exploring how poetry can disrupt or re-negotiate the barriers between the two activities. My first chapter explores the idea of ‘authority' in both science and poetry and considers how these authorities co-exist in the work of two poet-scientists, Miroslav Holub and David Morley. My second chapter considers the role of metaphor in science and the effect of transferring scientific terms into poetry, specifically with reference to the poetry of Michael Symmons Roberts who engages with the metaphors related to the human genome. In my third chapter I focus on collections by Ruth Padel and Emily Ballou that tell the life of Charles Darwin in verse. I discuss how these collections function as forms of scientific biography and show that poetic engagement with Darwin's thought processes reveals some of the similarities between scientific and poetic thinking. An area of science such as quantum mechanics may seem too complex for a non-scientist to respond to in poetry, but in my fourth chapter I show how Jorie Graham uses ideas from twentieth-century physics to re-think the materialism of the world and our perception of it. My final chapter is concerned with the relationship between ecopoetry and ecological science, with regard to the work of John Burnside. I show that although he is informed about scientific matters, in his poetry he suggests that science isn't the only way of understanding the world. Rather than framing science and poetry in terms of the ‘two cultures', this thesis moves away from antagonism towards productive interaction and dialogue. Whilst science and poetry are clearly very different activities, the many points of overlap and connection between them suggest that poetry is a resonant and unique way of exploring scientific ideas.

Doktor Moreau och jakten på den etiska figuren : Från misslyckat människoskapande till respektfulla relationer

Helsing, Sophie January 2015 (has links)
“Doctor Moreau and The Hunt for The Ethical Figure. From unsuccessful man-making to respectful relations with Jacques Derrida, Donna Haraway and H. G. Wells” In H. G. Wells’ science fiction novel, The Island of Doctor Moreau (1896), a scientist on a remote island in the Pacific Ocean attempts to create humans from animals. Wells draws on Charles Darwin’s theories on the origins of species and the descent of man to create a horror story in which the uniqueness of the human is called into question. This study uses the novel to investigate the re-emergent interest in human-animal relations, within the natural sciences as well as the arts and humanities, in the past twenty years. In what is often termed “the Animal Turn,” theorists such as Jacques Derrida and Donna Haraway, who are at the centre of this study, have dedicated a significant amount of their work to the animal question and in particular to the ethics of inter-species relationships. Furthermore this essay stages the interaction of fiction and theoretical discourse in an analysis that probes challenges inherent to the relations of humans to other species, such as the practice of eating meat, the killing of animals, and animal rights. Moreover, it considers how the figure of the animal has been used to define the human, as well as to dehumanize people in the justification of abuse and persecution. However, human-animal ethics also has positive connotations, discussed through the figures of positivity and possibility in play, sharing, contact and responsive responsibility. Taking its inspiration from Karen Barad’s method of diffraction, this study foregrounds new pattern-making while exploring how Derrida’s and Haraway’s strategies for formulating a new ethics are present in their use of tropes and figures. / Science fiction-romanen The Island of Doctor Moreau skrevs 1896 och handlar om hur en vetenskapsman på en avlägsen ö i Stilla havet försöker skapa människor av djur. Författaren H. G. Wells inspirerades av Darwins teorier om arternas uppkomst till att skriva en skräckberättelse där mänsklighetens unikhet sätts ur spel. Den här studien använder Wells text i syfte att undersöka hur relationen mellan människor och andra arter har kommit att få ett nytt intresse inom en mängd olika vetenskapliga, praktiska och konstnärliga ämnen i slutet av 1900-talet och början av 2000-talet, något som har kommit att kallas ”The Animal Turn”.  I centrum för studien återfinns teorier formulerade av filosofen Jacques Derrida och den feministiska vetenskapsteoretikern och biologen Donna Haraway. Båda två har ägnat stor del av sina respektive arbeten åt djurfrågan, framför allt med enträget intresse för hur ett etiskt förhållande mellan arter kan se ut. Studien låter romanen och de teoretiska texterna samverka i en analys som diskuterar utmaningar i människa-djur-relationer – som köttätande, dödande och rättigheter. Människan har till exempel använt sig av djuret för att definiera sig som människa, men också för att dehumanisera andra människor, och därmed kunnat utnyttja eller våldföra sig på dessa människor. Men människa-djur-etiken har också positiva aspekter: kontakt över språkgränser, att tillsammans utgöra världsmedborgare som alla består av och är beroende av varandra, att dela lek och arbete, att se och upptäcka den andre.  Med inspiration från Karen Barads användning av metoden diffraktion vill den här uppsatsen utforska Derridas och Haraways strategier för att formulera en ny etik genom bruket av figurer och troper.

塵與魂:狄金森、達爾文與演化詩學 / Dust and Spirit: Emily Dickinson, Charles Darwin, and Evolutionary Poetics

周庭加, Chou,Ting jJa Unknown Date (has links)
由於其個人獨特的生命背景與歷程,一般咸認為美國詩人艾蜜莉.狄金森(1830-1886)詩作中,充滿了對自然世界的細膩觀察以及精神世界的嚮往和追求。這樣的看法,固然是將狄金森的詩作,置放於十九世紀英國浪漫主義、美國愛默生的超越主義等文藝思想脈絡之下,以期盼引發及獲得對其詩作更深刻的詮釋與閱讀。然而,事實上,在十九世紀這百年當中,最重大的思想衝擊,莫如英國自然學者查爾斯.達爾文(1809-1882)於一八五九年所出版的《物種源始》(另譯《物種起源》)所帶來的影響為甚。達爾文所提出不假未知力量的物種演化理論,非但已成為今日科學/生物學研究的基石,同時也廣泛影響了十九世紀大西洋兩岸的社會、文化、藝術及科學等各層面的發展與演繹。 本論文擬從十九世紀「科學-宗教」、「物質-精神」之間的拔河與辯論為經,以發掘狄金森與達爾文兩人生命歷史當中的異同及互動為緯,透過閱讀狄金森的文字書寫(包括詩作與書信等)以及達爾文《物種起源》(初版及第二版),探討兩人於「演化」觀念上的交疊與對話。基於上述討論,我以為狄金森的文字書寫,藉由普遍出現於詩作裡、無論是自然領域,抑或觀念領域上的對立主題與意象,誠然為詩人企圖揉合十九世紀科學論述、宗教爭議與個人思想於詩的寫作之中;藉由生動的表現、積極的反省與回應各種衝突與對立的實體和觀念,來展現其迥異於全然唯心或全然唯物的「演化詩學」。 本論文共分為五章。在引論中,首先藉著閱讀現今生物行為學研究,帶入狄金森詩作中的生物與科學主題,企圖將狄金森放置於十九世紀達爾文及其演化觀念的脈絡下。第一章嘗試整理十九世紀「科學-宗教」、「物質-精神」之間的辯論,來檢視狄金森與達爾文兩人生命歷史中常被忽略的相似處與交集。第二章討論狄金森詩作中的科學主題,用以凸顯詩人對當代科學思想的發展所做的積極回應。第三章先討論十九世紀「科學方法與精神」的內涵,將達爾文《物種起源》與狄金森的詩作並置閱讀,從「死亡」、「演化路徑」、「視界的物質性」三個層面來發展鋪陳詩人的「演化詩學」。最後,檢視與思考前述各篇章所帶出的議題,並援引蕭沆(E. M. Cioran)思考文字與科學時代之間的關係、諾里斯(Margot Norris)所指出達爾文作為於今難已復見的「生物中心觀」文學傳統之濫觴,以及尼采「懷疑為人的兩棲本質」,總結提出狄金森「演化詩學」成為一種文學觀的可能。 / From the traditions of English Romanticism, Emersonian Transcendentalism, and the seclusion of the poet, Emily Dickinson’s poetry has generally been read and regarded as lyrical and spiritual. In addition, the most studies of Dickinson’s poetry tend to show the idiosyncrasy and uniqueness of the poet with her observations of Nature, use of language, feminine identity, or the mixture of these three topics. However, scholarly efforts over the years also indicate that for a better and fruitful understanding and appreciation of Emily Dickinson, we have to examine and interpret her life and writings under bigger ideological and cultural contexts of the nineteenth century. Among the innovations of knowledge and conceptions in the nineteenth century, Darwin’s materialistic theories to explain the evolution of species by means of natural selection, in the eyes of the naturalist’s contemporaries and modern people, are certainly still one of the most scientifically important and ideologically controversial ideas. In this study of Emily Dickinson’s poetry, I would like to argue that as a poet of great intellect, whose poems are filled with scientific contents and observations of the natural world, Emily Dickinson not only is familiar with Darwinian biological arguments but also incorporates evolutionary ideas, not limited to Darwin’s, into her poetic writings. Moreover, as Darwinian theories have triggered the debates between science and religion, the constant reflections on religious faith are also pervasive in Dickinson’s poetry and her correspondence. Thus, instead of reading Emily Dickinson’s writings straightforwardly under the framework of Darwinism, I would like to put Darwin and Dickinson in parallel—the transatlantic intersections of their lives and their works, The Origin of Species and Emily Dickinson’s poetry. Through examining these nineteenth-century historical and cultural figures and the interactions between different currents of ideologies, we will hopefully be able to see more clearly and uncover how Dickinson renders this well-known biological theory and further develops her own poetic evolution, which surpasses the materialistic and metaphysical boundaries in the physical as well as spiritual worlds.

Proposes his hypothesis about th origin of life relating the biological evolution mainly the Natural Selection Theory of Charles Darwin with the Dialectic Materialism of Karl Marx and Friedrich Engels. There are some disagreements about the nature of such relation, which is considered by some authors coherent and by others just adequate to political pressures of the Stanilist regime in the former Soviet Union. From a comparative analysis between the books of Engels mainly Dialectic of Nature, in with his conception of nature and dialectic materialism are present and Oparin s articles, this work shows that such concepts helped Oparin to develop his lage hypothesis with a sophistication in terms of argument, to the philosophical point of view as well as experimental / O bioquímico russo Alexandre Ivanovicth Oparin publica, em 1924, na antiga União Soviética, um artigo contendo sua hipótese acerca de um ponto considerado nevrálgico da história da biologia: o problema da origem da vida na Terra. Oparin propõe sua hipótese sobre a origem da vida relacionando o evolucionismo biológico, principalmente a teoria da seleção natural de Charles Darwin, com o materialismo dialético de Karl Marx e Friedrich Engels. Há divergências quanto à natureza de tal relação, considerada, por alguns autores, coerente e, por outros, forçada por pressões políticas presentes no contexto em que Oparin viveu, sob o regime stalinista da antiga União Soviética. A partir de uma análise comparativa entre os livros de Engels principalmente Dialética da natureza, no qual sua concepção de natureza e do materialismo dialético são presentes e publicações de Oparin, este trabalho mostra que tais concepções serviram a este último para o desenvolvimento posterior de sua hipótese, como uma certa sofisticação em termos de argumentos, tanto do ponto de vista filosófico como experimental

The goal of this thesis is to analyze Mivart´s critiques and Darwin´s answers, and to verify if they were scientifically well formulated and based considering the scientific context of that time. The reason for writing this work is an attempt to fill a gap in the History of Science about the scientific controversy between Mivart and Darwin on the role of natural selection in the origin of species. This work´s hypotheses are two: that Mivart´s critiques, despite being religiously motivated, were plausible scientifically, and that Darwin answered them fully. This research analyzes the primary sources of Mivart (Genesis of species) and Darwin's Origin of Species, and other secondary sources. The result reached was that Mivart´s critiques were indeed scientific, and that Darwin answered them according to the evidences and scientific knowledge then available / Esta pesquisa segue a linha de História e Teoria da Ciência que objetiva trazer esclarecimentos sobre a construção do pensamento científico através da discussão da fundamentação de hipóteses e teorias dentro do seu contexto histórico. O objetivo desta dissertação é analisar as críticas de Mivart e as respostas dadas por Darwin, e verificar se elas estavam bem formuladas e fundamentadas cientificamente considerando-se o contexto científico daquela época. A justificativa para a realização desta trabalho é tentar preencher uma lacuna em História da Ciência sobre a controvérsia científica entre Mivart e Darwin sobre o papel da seleção natural na origem das espécies. As hipóteses deste trabalho são duas: as críticas de Mivart, apesar de terem sido religiosamente fundamentadas, eram cientificamente plausíveis, e Darwin as respondeu satisfatoriamente. O aspecto teórico-metodológico foi a análise das fontes primárias de Mivart (Genesis of species) e de Darwin (Origin of species), e outras fontes secundárias. O resultado obtido foi que as críticas de Mivart eram científicas, e que Darwin respondeu-as conforme as evidências e o conhecimento científico da época

No. of bitstreams: 1 Andreza Polizello.pdf: 806973 bytes, checksum: 2f1d51dd54a25808c194bffdd9f6ab2c (MD5) Previous issue date: 2009-05-14 / Secretaria da Educação do Estado de São Paulo / Francis Galton (1822-1911) made important contributions in several fields of science. Among other things, he was the founder of the Biometric School developed by Karl Pearson and Walter Frank Raphael Weldon. The aim of this dissertation is to discuss Galton s ideas on inheritance developed during the period between 1855 (when he published his first works on the subject) and 1889 (when he published the book Natural inheritance), especially focusing his theory of stirps (1872), taking into account the other microscopic models of inheritance proposed in the 19th century. Besides that, it will compare Galton s theory of stirps to Darwin s hypothesis of pangenesis. Moreover, it will try to detect if there were significant changes in Galton s thought concerning the subject during this period. It will also try to elucidate if the low impact received by the theory of stirps was due to a weak foundation. This dissertation contains an introduction and five chapters. Chapter 1 presents some microscopic models of inheritance which were proposed during the 19th century. Chapter 2 discusses Darwin s hypothesis of pangenesis and its test made by Galton. Chapter 3 analyses Galton s theory of stirps. Chapter 4 discusses about the development of Galton s theory of heredity from 1865 to 1892. Chapter 5 provides some final remarks on the subject. This study led to the conclusion that Galton s proposal presented some peculiarities which differentiated it from the other ones of his time such as the experimental test of pangenesis, the performance of several experiments with peas, dogs and the study of genealogies and in addition to this, his concern in giving a statistical treatment to the data. A comparison between his several works showed a continuity of his thoughts on heredity with no significant changes / Francis Galton (1822-1911) trouxe importantes contribuições para diversos campos da ciência.

Além disso, comparará a teoria das estirpes de Galton com a hipótese da pangênese de Darwin. Procurará detectar se houve mudanças significativas no pensamento de Galton em relação ao assunto tratado durante esse período. Procurará também elucidar se o baixo impacto recebido pela teoria das estirpes se deveu a uma fundamentação fraca. Esta dissertação contém uma introdução e cinco capítulos. O Capítulo 1 apresenta alguns modelos microscópicos de herança que foram propostos durante o século XIX. O Capítulo 2 discute a hipótese da pangênese de Darwin e seu teste feito por Galton. O Capítulo 3 analisa a teoria das estirpes de Galton. O Capítulo 4 comenta sobre o desenvolvimento da teoria da hereditariedade de Galton de 1865 a 1892. O Capítulo 5 apresenta algumas considerações finais sobre o assunto. Este estudo levou à conclusão de que a proposta de Galton apresentou algumas peculiaridades que a diferenciavam das outras propostas de sua época tais como o teste experimental da pangênese, a realização de vários experimentos com ervilhas, cachorros e o estudo de genealogias e, além disso, sua preocupação em dar um tratamento estatístico aos dados. Uma comparação entre seus diversos trabalhos mostrou a existência de uma continuidade em seus pensamentos sobre hereditariedade e a ausência de mudanças significativas. Além disso, parece que o baixo impacto recebido pela teoria das estirpes de Galton não se deveu a uma fundamentação deficiente
