Building the «true evolutionism»: Darwin's impact on Henri Bergson's thought

The paper focuses on the importance of Darwin’s work for the shaping of Henri Bergson’s philosophy, bearing on mind that the two authors first intercepted symbolically in 1859, when On the Origin of Species was published and Bergson was born. Bergson studied the biological sciences of his time, whose results were integrated in a metaphysical thought. He belonged to spiritualistic positivism, a philosophy that goes from the positive data of sciences and finds the ultimate explanation of reality in a spiritual principle. He was interested in the positive evolution of the natural world and in the works of naturalists such as Lamarck, De Vries or Eimer. Darwin was among these authors, being responsible for a vision of evolution that went from the scientific level to other domains. Bergson defends the “insufficiency of pure Darwinism” by pointing out the necessity to compensate scientific evolution with an internal metaphysical reading of the real, which he considered to be “true evolutionism”. This criticism is the most visible aspect of the relations between both works. However, an attentive look verifies that Darwin’s influence overcomes the divergence of positions concerning the extent of “evolution”. The French philosopher knew not only the 1859’s bestseller, but also studies by Darwin about ethology, entomology and botany, which contributed to the fact that the naturalist’s impact gained fundamental importance in Bergson’s philosophical perspective.

España: evolutionism & religion, Century XIX

From the Englightenment to the middle of the 19th century, geological time and the antiquity of human beings received ever growing attention. This was caused by a series of events, such as: *the beginnings of experimentation in Geology (Buffon, 1778) *the development of the transformism (Lamarck, 1809) *the recognition and description of extinct animals (Cuvier, 1812) *as well as the studies made in alluvial deposits, caves and gravel beds, with brought to light artefacts, human rest and bone of extinguished animals (from John Frere, 1797, to Albert Gaudry, 1859). The development towards evolutionism (Darwin, 1859) came gradually. In Spain, all these currents found their echo: Spain, e.g. was the third country where the Palaeolithic remains were discovered (Verneuil and Lartet, 1863). Also the Darwin ideas were introduced forcefully, right from the beginning. But the change in worldview, which was prerequisite to these ideas, lead to polemic controversies in the political and religious realm. The most significant evidence was the official prohibition of the teaching Darwinism in public educational centres (1875). At theological level, thanks to the advance of the geologic knowledge, went leaving the literal interpretations of Biblical texts was eventually discontinued and replaced by more liberal interpretation. In some case, the process was difficult because some political, religious and scientific authors and researchers didn’t understand the new scientific ideas.

Sob o signo de Darwin? Sobre o mau uso de uma quimera

No ano de 2003 Francisco de Oliveria publicou um artigo intitulado "O Ornitorrinco" no qual fez considerações críticas sobre a conjectura politico-social daquele momento histórico. Tal artigo é permeado por um paralelo entre o evolucionismo darwinista e a visão do autor sobre a sociedade brasileira contemporânea. Entretanto, ao fazer tal analogia ele incorre numa série de equívocos teóricos sobre a teoria evolucionista. Tais equívocos consistem, em grande parte, numa substuição indevida entre aquilo que ficou conhecido como Darwinismo Social e a teoria neodarwinista como entendida pelos seus atuais proponentes. O presente trabalho identifica estes equívocos e os contextualiza dentro da teoria neodarwiniana. Além disso, fazemos um recorte histórico do processo de formação do pensamento evolucionista para enfatizar que a associação entre biologia e darwinismo social é mais complexa do que geralmente se assume.

Evolucionismo e genética do transtorno de estresse pós-traumático

Os autores discutem, a partir do conceito evolutivo, como a resposta de estresse, nas suas possibilidades de fuga e luta e de imobilidade tônica, pode levar a uma nova compreensão etiológica do transtorno de estresse pós-traumático. Através da análise dos agrupamentos de sintomas desse diagnóstico - revivência, evitação e hiperexcitação -, procuram correlacionar os achados neurobiológicos e evolutivos. As descobertas atuais sobre a genética do transtorno de estresse pós-traumático são resumidas e colocadas nessa perspectiva evolutiva, dentro de conceitos que possibilitam o entendimento da interação gene/ambiente, como a epigenética. Propõem que a pesquisa dos fatores de risco do transtorno de estresse pós-traumático deva ser investigada do ponto de vista fatorial, onde a somatória destes aumenta o risco de desenvolvimento do quadro, não sendo possível a procura da causa do transtorno de forma única. A pesquisa de genes candidatos no transtorno de estresse pós-traumático deve levar em consideração todos os sistemas associados aos processos de respostas ao estresse, sistemas dos eixos hipotálamo-hipofisário-adrenal e simpático, mecanismos de aprendizado, formação de memórias declarativas, de extinção e esquecimento, da neurogênese e da apoptose, que envolvem vários sistemas de neurotransmissores, neuropeptídeos e neuro-hormônios.

Apocalypse forever? International relations implications of 11 September

This is a contribution to ongoing discussion of the international relations issues raised by the terrorist attacks of 11 September 2001. It acknowledges apparent failings (of analysis or prediction) in the IR literature but then suggests the shortcomings are really the product of divergent traditions of analysis (behaviouralism, structuralism and evolutionism) which isolate different aspects of phenomena for attention. The paper then discusses the contrast between hard power and soft power - to help identify the distinctiveness of the new forms of terrorism (their non-linear objectives and the lack of proportionality involved). It concludes on an encouraging note by urging international cooperation as a solution, even in cases where the protagonists' resentments have tended to militate against conventional channels of dispute resolution.

As teorias da origem das espécies nos manuais escolares portugueses de Ciências Naturais (1905-1959)

O ensino das teorias da origem das espécies no sistema de ensino liceal português ainda não está completamente esclarecido. Esta investigação visou contribuir para essa clarificação, ao mostrar o modo como os autores dos manuais de Ciências Naturais destinados ao ensino liceal, fizeram essa transposição, no período compreendido entre 1905 e 1959. Para tal, estudaram-se as perspectivas e as teorias da origem das espécies, os mecanismos e as provas do evolucionismo que apresentaram. Os resultados mostraram que a tipologia diversificada de mecanismos e de provas de evolução que transpuseram, evidencia que a argumentação em prol do evolucionismo continuou a dominar o discurso dos autores dos manuais desse período. Contudo, concorreram nesses manuais diversas explicações para a evolução das espécies, como o lamarckismo, o neolamarckismo, o darwinismo, o neodarwinismo, a ortogénese, o mutacionismo e o transformismo teísta. The teaching of the origin of species theories in the Portuguese secondary education hasn’t been completely clear yet. This investigation aimed to contribute to this clarification, showing the way the authors of secondary schools science textbooks, did that transposition, from 1905 to 1959. Therefore, there were studied the perspectives and the origin of species theories, the mechanisms and proves of evolutionism that they had presented. The results showed that the diverse typology of mechanisms and proves of evolution they had transposed, showed that the argumentation in favor of the evolutionism continued to domain the discourse of school textbooks authors from this period. However, there were many explanations in these textbooks for the evolution of species, such as Lamarckism, neoLamarckism, Darwinism, neoDarwinism, Orthogenesis, Mutationism and Theistic Evolutionism.

Antero de Quental: a última palavra da natureza é 'ética'

Antero de Quental (1842-1891) is best known for his poetic work. Nevertheless, alongside this literary work, and in close correlation with it, he produced a corpus of philosophical texts of great depth and relevance. Nature composes a unifying thematic core for his work, and is implicit throughout the author’s entire work. In this paper, we seek to establish the main tendencies of his Evolutionism, both from the positive and metaphysical points of view. On his last work (Tendências gerais da filosofia na segunda metade do século XIX), the author talks about "good" as the fundamental principle of all human actions and of nature itself: the last word of nature is written by the human consciousness whenever a good action is performed. This opens the door to a spiritual Evolutionism and explains the moral world view that we can find in Antero de Quental's thought.

Aux archives de l'animisme. Ethnographie et théorie de la "religion sauvage" chez Edward Tylor

En 1871, Edward Tylor rejeta fermement les récits de son temps qui niaient l'existence de croyances religieuses chez certains peuples alors considérés comme sauvages. C'était le cas, tout particulièrement, de l'explorateur victorien Samuel Baker, dont l'autorité ethnographique fut mise en cause à travers la citation de quelques voyageurs étrangers, dont deux français, qui avaient également observé les peuples nilotiques. Contrairement à d'autres sources de Primitive Culture, la qualité de ces ethnographies oubliées était, hélas, tout à fait médiocre ; mais elles permirent à Tylor de faire l'une des affirmations les plus décisives de son œuvre, celle de l'universalité de l'animisme. Ce passage capital - concernant des peuples qui deviendront célèbres dans l'histoire de l'anthropologie, à commencer par les Nuer - recèle par ailleurs une dimension additionnelle. Tylor voulait élargir à tout être spirituel les critères d'identification d'une religion, sauf que les ethnographes du Nil Blanc suggéraient que ces rudes populations croyaient bel et bien en un être suprême. Le dossier du monothéisme était comme anticipé par la force de ces données ; mais il ne faut pas y voir une contradiction de la part de Tylor. Au contraire, cette dialectique imprévue entre l'ethnographie et la théorie permet de mieux saisir la portée du concept d'animisme dont il fut le créateur.

Há compatibilidade entre a "tecnologia social" de Nelson e a "causalidade vebleniana" de Hodgson?

Is there compatibility between Nelson's 'Social Technology' and Hodgson's 'Veblenian Causality'? This paper aims to discuss the role and the relationship among the concept of institutions and the economic growth process, through the Neo-Schumpeterian and Institutionalist approaches. Both of them constitute a new research agenda differentiated and opposite to the mainstream. In the first part of the paper we discuss the research agenda proposed by Richard Nelson who emphasizes the necessity to unpack the institution concept throughout the social technology notion. In the second part we discuss Geoffrey Hodgson's contribution that suggests inserting this process in an evolutionary perspective, which has in habits, norms and social behavior his major characteristic.

Histoire de l'interprétation de la transition néolithique : évolution des théories, modèles et hypothèses

Ce mémoire reconstitue l’histoire des théories, modèles et hypothèses qui ont été formulés, principalement en archéologie, afin d’expliquer la naissance de l’agriculture qui correspond, du point de vue chronologique, à la transition (ou révolution) néolithique. Ces schèmes explicatifs sont décrits chronologiquement depuis la naissance de l’archéologie préhistorique, dans la première moitié du XIXe siècle, jusqu’à maintenant. Ils sont classifiés en fonction des principales écoles qui ont joué un rôle prédominant en archéologie préhistorique depuis son origine, soit : l’évolutionnisme multilinéaire, l’école culturelle-historique, le processualisme, le néodarwinisme et le postprocessualisme. Les théories spécifiques (dites de « niveau mitoyen » ou « régionales ») qui ont été avancées par ces écoles sont présentées dans leur ordre chronologique, soit (principalement) : les théories de la dessiccation ou de l’oasis, des flancs de colline, de la périphérie, du stress démographique, du festin compétitif, de la révolution des symboles, etc. Ce mémoire pose enfin les jalons d’une théorie multifactorielle qui intègre ou synthétise les principaux facteurs qui ont pu influer sur la naissance de l’agriculture et sur la transition néolithique.

Consideracoes sobre o methodo de interpretacao funcionalista na geografia.

Functionalism, in its postulates and in its methods, can be seen not only as a reaction to geographical positivism and evolutionism but as a reflection of political tendencies and interests in the 20th century. Brazilian academic geography of the functionalist school showed itself resolute in attacking Darwinist interpretations, but concerned itself very little with theoretical systematization, methodology, discussion or reflection. -J.Naylon
