This junior/senior level text is devoted to a study of first-order logic and its role in the foundations of mathematics: What is a proof? How can a proof be justified? To what extent can a proof be made a purely mechanical procedure? How much faith can we have in a proof that is so complex that no one can follow it through in a lifetime? The first substantial answers to these questions have only been obtained in this century. The most (...) striking results are contained in Goedel's work: First, it is possible to give a simple set of rules that suffice to carry out all mathematical proofs; but, second, these rules are necessarily incomplete - it is impossible, for example, to prove all true statements of arithmetic. The book begins with an introduction to first-order logic, Goedel's theorem, and model theory. A second part covers extensions of first-order logic and limitations of the formal methods. The book covers several advanced topics, not commonly treated in introductory texts, such as Trachtenbrot's undecidability theorem. Fraissé's elementary equivalence, and Lindstroem's theorem on the maximality of first-order logic. (shrink)

In Thomas Thomson's System of chemistry of 1802 Bergman and Scheele are actually considered as creators of the analytical concept of an element. With regard to this, a detailed investigation of the work of Bergman and Scheele shows that Thomson's statement contains mistakes as well as inadmissable simplifications and generalizations. It is correct, however, that Bergman in 1774–1777 specifically anticipated in essential aspects the analytical element concept proposed by Lavoisier in 1787–1789.

Der auf Kants kritischer Philosophie fußenden Philosophengeneration galt Herder als hoffnungslos anachronistischer, vorkritischer Philosoph, dessen Denken für das eigene philosophische Programm keine Relevanz zukomme. Das im folgenden dokumentierte Projekt geht demgegenüber von der Hypothese aus, daß Herder in die Vorgeschichte der Philosophie des deutschen Idealismus gehört, daß er Vorläufer und Weggenosse der nachkantischen Philosophengeneration war. Der vorliegende Band versammelt Arbeiten, die zur Begründung und Diskussion dieser Auffassung in unterschiedlicher Weise beitragen: es geht um die Konturierung der für diese Thematik relevanten (...) Aspekte von Herders eigenem Denken, um die Erschließung der gemeinsamen philosophischen und wissenschaftshistorischen Grundlagen des Herderschen Denkens und der Philosophie des deutschen Idealismus, nicht zuletzt geht es um die Erarbeitung der Rezeption von Herders Philosophie in der nachkantischen Philosophengeneration.

Der vorliegende Band stellt ein erstes Grundlagenwerk zur Imaginationsforschung in der Ökonomie dar. Er erforscht die ökonomische Theoriegeschichte (auch mit Bezug auf die Philosophiegeschichte) und fragt, welche Bilder und Selbstbilder über Menschen, über das wirtschaftliche System und über die Zukunft in ökonomischen Theorien enthalten sind. Wie ist die Beschäftigung mit Imaginationen im Mainstream der Wirtschaftswissenschaften verloren gegangen und wie kann sie wiederbelebt werden? Prof. Dr. Walter Otto Ötsch ist Professor für Ökonomie und Kulturgeschichte an der Cusanus Hochschule für Gesellschaftsgestaltung. Prof. (...) Dr. Silja Graupe ist Professorin für Ökonomie und Philosophie und Leiterin des Instituts für Ökonomie der Cusanus Hochschule für Gesellschaftsgestaltung. (shrink)

Neste texto, refletimos acerca da educação escolar no meio rural brasileiro estabelecendo interface com os direitos humanos. Para alcançar este objetivo, fazemos uma retrospectiva histórica da educação oferecida pelo Estado à população rural, demonstrando que sistematicamente tem sido direito negado do ponto de vista do acesso, da continuidade e da qualidade social do ensino. Contudo, com o processo de democratização da sociedade na década de 1980 e da emergência de movimentos sociais, é reivindicado o direito universal à educação consignado na (...) Constituição Federal de 1988 como “direito de todos e dever do Estado”. A partir de meados de 1990, uma política educacional contra-hegemônica é construída por um conjunto de atores coletivos, constituindo o Movimento Nacional de Educação do Campo, denominada de Educação do Campo. Se a grande conquista reside no marco regulatório no qual se pode visualizar uma educação que considera a identidade, especificidade e diversidade dos sujeitos do campo, isso não significa a garantia desses direitos. Do ponto de vista metodológico, a abordagem analítica desta reflexão se orienta pela perspectiva epistemológica do materialismo histórico, tendo por base de pesquisa elementos da legislação educacional brasileira e o diálogo com autores que apontam para novos horizontes da educação como direito social. Como resultado desta investigação, apontamos desafios a serem enfrentados, entre eles o consórcio dos entes federados nem sempre afinado no cumprimento do marco regulatório da Educação do Campo; poucas iniciativas de formação inicial e continuada específica para professores da Educação do Campo; estrutura material precária das escolas; o material didático-pedagógico contempla conteúdos descontextualizados e inadequados às peculiaridades locais, às vivências e necessidades dos usuários da escola; ausência de Projeto Político Pedagógico, Currículo e calendário escolar capazes de, ao mesmo tempo, dar conta de oferecer o conhecimento socialmente produzido pela humanidade e atender a diversidade, especificidade dos sujeitos com direito ao acesso à escola onde vivem e uma educação omnilateral, que não dissocia a formação humana e profissional. Concluímos identificando uma profunda brecha entre o marco regulatório da Educação do Campo conquistado e a garantia real de uma educação cidadã e profissional de qualidade a ser ofertada à população do campo.

Mario Bunge is an important philosopher of science. But he does not limit himself to using his “truth-technology” in his particular philosophical discipline. For decades, he has also endeavored to achieve an independent profile as a public intellectual on the basis of his wide-ranging competence. To this end, he authoritatively criticizes authors who market themselves to the public as anti-scientists or as pseudo-scientists. On his home continent of Latin America, Mario Bunge is regarded as a role model because he has (...) achieved international recognition like no other South American philosopher before him. (shrink)

Over the last two decades, the Japanese notion of ba, introduced by Ikujiro Nonaka and his associates to the West, has come to play an important role in management theory. This notion, which has been roughly translated as ‘place’ or ‘topos,’ stresses the importance of processual spatial thinking for economics and management alike. As such, it echoes and amplifies recent voices in the business world, which argue that we must understand business strategy in terms of space, that is to say, (...) as an expression of the dynamics of social interaction which involves such factors as connectivity, information flow, external versus tacit knowledge, etc. Despite many efforts, the barriers for fully integrating ba into the body of Western management literature will remain for as long as its underlying assumptions are defined by ontologically static categories. This article is an attempt to overcome this theoretical bottleneck, first by critiquing the sub optimal approach to processual problems generated by conventional Western business theories, which can neither recognise their hidden background assumptions about space nor transcend them, and second, by explaining, within the framework of comparative analysis, how ba leads to a new processual and dynamic account of business life. Our overall aim is to demonstrate how a new processual notion of space enables a deeper, more integrated understanding not only of the nature of the firm, but also of the role managers play within firms.

Der interkulturelle Dialog mit der japanischen Philosophie erhellt die verborgenen, unreflektierten Denkgewohnheiten der Wirtschaftswissenschaften. Die Andersartigkeit japanischen Denkens macht den impliziten methodologischen Grundrahmen der Okonomie sichtbar, verweist kritisch auf Widerspruche sowie Erklarungslucken und zeigt Alternativen auf. Ansprechend und leicht verstandlich geschrieben, bricht das Buch mit der tief in der Okonomie verwurzelten Vorstellung der Welt als einer Gesamtheit unabhangiger, essentiell unveranderlicher Dinge bzw. Individuen und zeigt die Wirtschaft als ein interdependentes Gestaltungsgeschehen fernab jeder mechanischen Gesetzmassigkeit auf. Das okonomische Denken wird so (...) uber Kultur- und Disziplingrenzen hinweg auf neue, ungewohnliche Weise kreativ.". (shrink)

In the parlance of modern Japanese philosophy, the term Basho denotes a field of experience underlying all conceptions of reality, while remaining itself conceptually ungraspable. The Basho of Economics, then, refers to the economy s hidden experiential ground, which has never been explicitly scrutinized, as such, by mainstream economics. We uncover this ground by discerning the tacit presuppositions of classical and neo-classical theories from the perspective of modern Japanese philosophy. In particular, we draw attention to the traditional atomist assumptions implicit (...) in their equilibrium-centered models. By breaking through these assumptions, we reconstruct the economy as a functional and relational world of habitual and creative activity outside of the scope of mechanical laws.". (shrink)
