The author's purpose is to read the main work of Euclid “with modern eyes” and to find out what knowledge a mathematician of today, familiar with the works of V. D. Waerden and Bourbaki, can gain by studying Euclid's “theory of magnitudes”, and what new insight into Greek mathematics occupation with this subject can provide. The task is to analyse and to axiomatize by modern means (i) in a narrower sense Book V. of the Elements, i.e. the theory of proportion (...) of Eudoxus, (ii) in a wider sense the whole sphere of magnitudes which Euclid applies in his Elements. This procedure furnishes a clear picture of the inherent structure of his work, thereby making visible specific characteristics of Greek mathematics. After a clarification of the preconditions and a short survey of the historical development of the theory of proportions (Part I of this work), an exact analysis of the definitions and propositions of Book V. of the Elements is carried out in Part II. This is done “word by word”. The author applies his own system of axioms, set up in close accordance with Euclid, which permits one to deduce all definitions and propositions of Euclid's theory of magnitudes (especially those of Books V. and VI.). In this way gaps and “tacit assumptions” in the work become clearly visible; above all, the logical structure of the system of magnitudes given by Euclid becomes evident: not “ratio” — like something sui generis — is the governing concept of Book V., but magnitudes and their relation “of having a ratio” form the base of the theory of proportions. These magnitudes represent a well defined structure, a so-called “Eudoxic Semigroup” with the numbers as operators; it can easily be imbedded in a general theory of magnitudes equally applicable to geometry and physics. The transition to ratios — a step not executed by Euclid — is examined in Part III; it turns out to be particularly unwieldy. An elegant way opens up by interpreting proportion as a mapping of totally ordered semigroups. When closely examined, this mapping proves to be an isomorphism, thus suggesting the application of the modern theory of homomorphism. This theory permits a treatment of the theory of proportions as developed by Eudoxus and Euclid which is hardly surpassable in brevity and elegance in spite of its close affinity to Euclid. The generalization to a “classically” founded theory of magnitudes is now self-evident. (shrink)

Esse texto tem por objetivo apresentar em linhas gerais a proposta de Otfried Höffe sobre a república mundial. Para tanto, iniciar-se-á com o ponto de partida de Höffe, a saber, o fenômeno da globalização, de onde são apontadas as principais atividades e problemas da república mundial. Em seguida, passa-se a analisar os dois níveis da proposta, o nível nacional e o nível internacional ou global da república mundial. Por fim, concluir-se-á com uma tentativa de comparação da proposta de Höffe com (...) a ideia de uma federação de Estados livres apresentada por Immanuel Kant em À paz perpétua. (shrink)

Este artigo pretende apresentar o tema da formação humana conectado à incapacidade de pensar, tecendo considerações sobre o problema do mal no pensamento de Hannah Arendt. A autora é conhecida como pensadora da política que concentrou atenção especial ao problema do mal que assolou o mundo na primeira metade do século XX. A partir da análise de Origens do Totalitarismo, de 1951, e de Eichmann em Jerusalém: um relato sobre a banalidade do mal, de 1963, pretende-se refletir acerca dos mecanismos (...) que produzem o adormecimento da capacidade de pensar frente à necessidade da formação humana. A partir dessa análise, se perceberá que o problema do mal assume um viés radical, uma possibilidade de destruição completa do humano. Na análise do caso Eichmann, Arendt percebeu que o réu agia banalmente, manifestando sua incapacidade de pensar, o que tornou possível a normalização da insensibilidade frente o diferente. Portanto, a banalidade do mal implica na incapacidade de pensar, uma ameaça sempre constante à formação humana. (shrink)

O presente texto visa explicitar o significado cosmopolita da filosofia de Immanuel Kant. Essa explanação passará pelas definições de ‘filosofia’, ‘filósofo’, ‘ensino’ e ‘filosofar’. Procurará mostrar que a própria constituição do conceito de filosofia ainda preserva a sua raiz grega de ‘amor à sabedoria’; que é necessário cultivar esse ‘amor à sabedoria’ para, a partir daí, aprender a raciocinar; que o filosofar possui um direcionamento prático que visa o esclarecimento, isto é, a emancipação da tutela alheia.

More widespread farming of species not typically used as livestock may be part of a sustainable approach for promoting human health and economic prosperity in a world with an increasing population; a current example is peccary farming in the Neotropics. Others have argued that species that are local to a region and which are usually not farmed should be considered for use as livestock. They may have a more desirable nutrient profile than species that are presently used as livestock. It (...) may also reduce the pressure from hunting on other wild species, and cause less environmental damage than exotic species. We propose a sentiocentric utilitarian framework that could be used to decide whether species that are local, but generally not used as livestock, should be farmed. To illustrate the use of our decision-making framework, we employ two contrasting neotropical case studies: the Spotted Paca (Cuniculus paca) and the Capybara (Hydrochoerus hydrochaeris). We argue that it may be acceptable to use non-sentient species that are typically not farmed as livestock. However, research should determine whether farming them offers human, environmental or sustainability benefits. In addition, we recommend that if invertebrate species are considered for farming, research should be conducted to determine the likelihood that they are sentient. Finally, given the ethical failings of current livestock farming practices, we argue that a high bar must be met if ‘new’ species that are sentient are to be farmed. (shrink)

Die Qualität dieser Bonner katholisch-theologischen Dissertation des Jahres 2002, die für die Drucklegung noch erweitert und auf den neuesten Stand gebracht wurde, wird schon daraus ersichtlich, daß sie von Walter Brandmüller in die von ihm herausgegebene Konziliengeschichte aufgenommen wurde. Das Ziel der Studie ist ein primär theologisches, das den Horos des VII. Ökumenischen Konzils „als das zur Entscheidung in der Ikonenfrage vorgelegte amtliche Dokument … ernstnehmen“ will. „Dies bedeutet einerseits, den Horos in seiner Binnenstruktur zu erschließen und ihn andererseits auf (...) philologisch-hermeneutischem Weg im Licht gattungsverwandter Texte früherer Konzilien und der Akten des Zweiten Konzils von Nizäa als Ergebnis eines Meinungsbildungsprozesses zu interpretieren“ (S. XVIII). Leider schließt der Verf. bei seinem an erster Stelle genannten Anliegen alle politischen und kirchenpolitischen Aspekte, zum Beispiel die Zielstellungen der Kaiserin Eirene und die bedeutsame Rolle des Patriarchen Tarasios, um nur einiges zu nennen, bei der Interpretation aus und verschließt sich so notwendigen Ansätzen für ein tieferdringendes und umfassenderes Verständnis. Denn beider Bemühen um den Erhalt der Einheit der Kirche bestimmten Planung, Verlauf und Ergebnisse des Konzils in entscheidender Weise. Das kommt in dieser Studie nicht zum Ausdruck, worunter dann natürlich auch die Interpretation der einzelnen behandelten Texte leidet. Immer noch lesens- und bedenkenswert sind zu diesem Problemkreis die Ausführungen von P. Speck, Kaiser Konstantin VI., München 1978, 135–179. Es ist eben nicht mehr ausreichend, wenn der Verf. für diese Zusammenhänge auf die in dieser Hinsicht unzureichende Darstellung von G. Dumeige, Nizäa II, Mainz 1985, verweist (S. XIX Anm. 9), die ja aus heutiger Sicht auf fragwürdigem Textfundament errichtet ist. Das betrifft dann auch einen Teil des zweiten Anliegens des Verf., nämlich die Beurteilung der Überlieferung der Akten des VII.Ökumenischen Konzils. Paul Specks Frontalangriff auf die Zuverlässigkeit der Akten, der ja „in der Tat an die Grundlagen“ der Ausführungen von Uphus rührt, pariert dieser völlig unzureichend, wenn er ohne eine rechte Begründung nur von erheblichen Zweifeln an den Hypothesen Specks spricht (S. 38 Anm. 1, etwas ausführlicher S. 331f.). Noch gewichtiger ist die neuerdings von Erich Lamberz, der eine kritische Edition der Akten des Konzils vorbereitet, geäußerte Warnung: „Eine Darstellung des Konzils, die den überlieferten Text der Akten – und das gilt erst recht für den bei Mansi abgedruckten Text – als selbstverständliche Grundlage der Forschung nimmt, sollte in Zukunft wohl nicht mehr möglich sein.“ (E. Lamberz, Die Bischofslisten des VII. Ökumenischen Konzils [Nicaenum II], München 2004, 37). (shrink)

Este artigo visa contribuir com o entendimento da formação humana ocidental e de seus desafios contemporâneos, em meio ao crescente desenvolvimento da natureza humana e de suas reflexões. Visando fazer frente a essas perspectivas, profundamente marcadas pela fraternidade, diálogo e compromisso, cujo pano de fundo é São Francisco de Assis, considerando que suas vivências contribuírem para a formação humana e educativa da humanidade. Nesta dimensão, o artigo pretende realizar um resgate de cunho teórico/filosófico, que possibilite a construção de uma abertura (...) dialógica capaz de evidenciar outras possibilidades de educar, nas quais se possa vislumbrar o emergir de outras experiências no campo educacional e pedagógico. Assim posto, o trabalho se concentrará em dois princípios básicos de atuação e entendimento teórico prático. Em primeiro lugar será efetuada uma discussão teórica sobre a temática, fraternidade como elemento motor da formação humana ocidental. Em seguida, será abordado o diálogo como caminho, elemento fundamental das relações no processo educacional. Com isso, se perceberá que o processo educativo é lugar de diálogo fraterno, no qual novos debates e saberes emergem, possibilitando, assim, novas possibilidades para a formação humana e integral.

Nos primeiros anos de seu pontificado, Papa Francisco fez pouco uso da palavra ‘bioética’. Quando fez menção à palavra, empregou-a no sentido formal, para tratar de alguma comissão, e não para manifestar uma posição. Mas, a partir de 2018, Francisco assumiu uma posição bem definida em relação à bioética, afirmando que os nossos tempos precisam ampliar a visão tradicional da bioética para uma visão de bioética global, pois não é mais possível pensar a saúde, o bem-estar e a realização humanas (...) de forma independente da saúde da totalidade da vida da biosfera. Essa bioética global, afirma Francisco, tem as suas bases na Laudato Si. Se o posicionamento escrito de Francisco sobre a bioética não ocorreu de forma imediata ao iniciar seu pontificado, a opção do pontífice de “começar” seu pontificado em Lampedusa, acolhendo migrantes e refugiados, deixou evidente qual seria o compromisso de sua Igreja. As duras palavras proferidas em Lampedusa, de que nos tornamos insensíveis aos gritos dos outros e que globalizamos a indiferença, tornando-nos incapazes de chorar pelo outro, deram o tom da sua missão. Nesse sentido, este artigo pretende investigar o pensamento bioético defendido pelo Papa Francisco a partir de documentos, encíclicas, homílias e cartas por ele escritas. (shrink)

Historicamente, as humanidades têm sido essenciais para a educação, uma vez que são consideradas como disciplinas fundamentais para a formação de cidadãos democráticos. A partir dessa conjectura, esse artigo visa refletir sobre a importância das competências no ensino de humanidades para a formação de cidadãos democráticos. Para isso, realizamos uma pesquisa de cunho bibliográfico, baseada no pensamento de Martha Nussbaum sobre as competências necessárias para o desenvolvimento de uma cidadania democrática (2015). O desenvolvimento de competências no ensino de humanidades promove (...) a autonomia do estudante no âmbito pessoal, profissional, intelectual e político para o enfrentamento dos desafios da sociedade. Essas competências permitem aos estudantes enfrentar a realidade e as necessidades humanas com senso crítico e consciência de sua responsabilidade como pessoa em um meio social, político e cultural.

O presente artigo visa analisar a proposta construtivista rawlsiana na qual se pode visualizar a influencia da teoria da escolha racional da filosofia prática kantiana. Rawls, apesar de declarar-se herdeiro de Kant, assume sua própria concepção construtivista, a saber, um construtivismo político, enquanto que o filósofo alemão, segundo ele, apresenta um construtivismo moral fundamentado no idealismo transcendental. A posição original, por sua vez, situa as partes de maneira equitativa considerando-as iguais e livres. Assim, a construção dos princípios da justiça nesta (...) posição é autônoma, ou seja, a escolha é realizada sem influências heterônomas, tais como classe social, talentos pessoais, etc. A proposta da justiça como equidade é a construção de princípios básicos endossados publicamente os quais regem de maneira justa a estrutura básica da sociedade democrática.

RESUMO Este artigo apresenta e discute acontecimentos que emergiram no decorrer de uma pesquisa-intervenção com jovens, visando problematizar as contribuições para a formação ética, estética e política tanto dos pesquisadores como dos participantes. Oficinas estéticas mediadas por linguagens artístico-visuais consistiram no modus operandi da pesquisa-intervenção, sendo os acontecimentos relativos à oficina de graffiti o foco das análises aqui apresentadas. Participaram dessa oficina entre 20 a 25 jovens matriculados em uma escola pública municipal de Florianópolis/SC, com idades entre 13 e 16 (...) anos. As atividades foram coordenadas por bolsistas de IC e extensão, graduandos de psicologia, e um bolsista AT, grafiteiro. Os registros das atividades foram feitos via filmagens, fotografia e registros em diário de campo. As análises foram realizadas a partir de uma perspectiva dialógica, com foco na responsividade que conota as ações e pauta a condição alteritária da existência.ABSTRACT This paper presents and discusses events that emerged in the course of research involving an intervention conducted with youngsters. The objective was to discuss contributions to ethical, aesthetic and political formation of both the researchers and participants. Aesthetic workshops mediated by artistic-visual languages consisted of the modus operandi of the intervention research, and the events related to a graffiti workshop were the focus of this analysis. From 20 to 25 youngsters, aged between 13 to 16 years old and enrolled in a city public school in Florianópolis, SC, Brazil participated. The activities were coordinated by undergraduate research assistants, senior psychology students, and one graffiti artist who received a Technical Support scholarship. The activities were filmed, photographed and recorded in a field diary. The analyses were conducted from a dialogic perspective focusing on responsiveness that connotes the actions and grounds the otherness nature of existence. (shrink)

Desde o Concílio Vaticano II, a Igreja Católica tem motivado o progresso social da humanidade em prol de uma educação que envolva o “bem comum” e o “direito universal”. O Papa Francisco propõe a celebração de um Pacto Educativo Global, unindo toda a sociedade para que se renove o amor por uma educação mais aberta e inclusiva em prol das futuras gerações. Através de políticas públicas coerentes com as múltiplas realidades, valorizando uma educação centrada na pessoa em consonância com o (...) coletivo, direcionando para uma educação humanizadora com a meta de formar seres humanos com valores éticos e morais. Uma educação em que o ato de ensinar e aprender seja ressignificado no que já se traz de bom e que realize, assim, transformações profundas nos espaços, nas culturas e nos diferentes ambientes institucionais, com os quais colabora-se na construção, melhoria e mudança em prol de um mundo mais solidário e fraterno, começando pela transformação de cada pessoa humana.

Nun liegt dieses große prosopographische Werk in erstaunlich kurzer Zeit abgeschlossen vor. Noch weit mehr als bei der PLRE (geringere Personenzahl) und dem PLP (zwar viel größere Personenzahl, jedoch oft leichtere Auffindbarkeit durch differenzierende Familiennamen) bedurfte dieses Instrumentum studiorum einer Aufschlüsselung durch umfassende Register. Wie beim PLP ist auch hier passenderweise auf den Seiten 7–84 ein vollständiges, erneuertes Abkürzungsverzeichnis vorangestellt (Quellen, Sekundärliteratur und Zeitschriftensiglen). Darauf folgen sehr willkommene Addenda und Corrigenda (S. 85–134), in die erfreulicherweise auch so manches aus meinen (...) ausführlichen Rezensionen (in BZ 92–94) eingeflossen ist. Der Hauptteil des Bandes mit den Indices (angeführt werden die Nummern und Namen der in der PMBZ behandelten Personen) wird eingeleitet durch eine Auflistung sämtlicher (sinnvoller) Namensvarianten, Familiennamen und Beinamen (S. 143–166). Danach folgt ein eher unerwartetes, vermutlich auch nicht sonderlich wichtiges Verzeichnis der Quellenstellen (S. 167–215, hier werden nur die Nummern angeführt). Als sicherlich bedeutendstes Register ist das der Titel und Berufe zu betrachten, durch das ja erst umfassende Studien zur Verwaltungs-, Wirtschafts-, Sozialgeschichte usw. ermöglicht werden bzw. erhebliche Erleichterung erfahren. Den Abschluß bilden – auch hier folgt die PMBZ dem Vorbild des PLP – die geographischen und topographischen Namen, deren Auflistung im Rahmen einer Prosopographie ja nicht unbedingt zu erwarten ist.

Selected articles of Ēṭukūru Balarāmamūrti on Marxist philosophy; includes contributed on his life and work.

Can there be such a thing as moral science, or a science of morality? And if so, what sense has the word science in such a connection? In the middle of the last century such a question would probably have seemed superfluous. Utilitarians, Comtists, and not a few “evolutionists” would all have claimed to be moralists, with this advantage over the metaphysical or theological moralists of an earlier day that their own moral doctrines were “scientific”.

David Ricardo was a hugely influential British political economist and stock trader. This volume, first published in 1923, contains five important pamphlets published by him, edited and with an overarching introductory essay by E. C. K. Gonner. Each essay relates either to monetary and financial subjects - including the high price of Bullion, monetary theory and the position of the Bank of England - or to the agricultural conditions of Britain and proposed solutions to the problems discussed. This is a (...) fascinating and detailed work, which will be of great value to those with an interest in Ricardo’s theories and British economic history. (shrink)

Tsc question of the date of Ctesibius has been much obscured of late years by those German scholars1 who assert that Ctesibius the pneumatic and hydraulic engineer mentioned by Vitruvius IX. 8. 2 is distinct and separate from Κτησίβιος Κτησίβιος μηΧανικός who is mentioned by Athenaeus Mechanicus , Philo of Byzantium , and Hedylus ap.

Robert E. Butts (1928-1997) was a philosopher and historian of science whose central concerns were the distinction between the rational and the irrational. He viewed scientific rationality as our major defence against the various conditions that encourage witch hunts and similar outbursts of irrationality, with all their attendant pain and terror. Butts saw himself as a pragmatic realist, combining what he took to be the best aspects of logical empiricism with a historically informed pragmatism, deeply appreciative of the methods of (...) science, trying to describe a kind of rationality essential in the struggle to preserve human values. This volume gathers previously unpublished essays and lectures with some previously published, thematically related essays. It includes essays and lectures on philosophical aspects of the European witch hunt, on scientific rationality and methodology, and on the relationships between science and philosophy exhibited in the writings of such historically significant figures as Leibniz, D'Alembert, Hume, Kant, Carnap and Kuhn.
