An axiomatic theory is formulated which describes a class of “yes-no” experiments, involving a fixed basic source, a fixed basic detector, and various filters. It is assumed that all filters considered can be constructed from a setP of primitive filters by composition and stochastic selection. Two physically plausible axioms are formulated which allow us to define the concept of asystem in the present context (cf. Definition2.4). To each system we can attach anorder unit module ( $^\circ \hat V, ^\circ \hat (...) V_ + , |1\rangle , \langle 1|$ ) (cf. Definition5.1) whereby ( $^\circ \hat V, ^\circ \hat V_ + , |1\rangle ,$ ) is acomplete, separable order unit space. Two additional axioms are proposed which have the effect that the space ( $^\circ \hat V, ^\circ \hat V_ + , |1\rangle ,$ ) becomes isomorphic to the order unit space underlying a JB-algebra, at least in the case where $^\circ \hat V$ isfinite dimensional (cf. Corollary7.9). (shrink)

The present paper is the first part of a work which follows up on H. Kummer: “A constructive approach to the foundations of quantum mechanics,”Found. Phys. 17, 1–63 (1987). In that paper we deduced the JB-algebra structure of the space of observables (=detector space) of quantum mechanics within an axiomatic theory which uses the concept of a filter as primitive under the restrictive assumption that the detector space is finite-dimensional. This additional hypothesis will be dropped in the present paper.It turns (...) out that the relevant mathematics for our approach to a quantum mechanical system with infinite-dimensional detector space is the noncommutative spectral theory of Alfsen and Shultz.We start off with the same situation as in the previous paper (cf. Sects. 1 and 2 of the present paper). By postulating four axioms (Axioms S, DP, R, and SP of Sec. 3), we arrive in a natural way at the mathematical setting of Alfsen and Shultz, which consists of a dual pair of real ordered linear spaces 〈Y, M〉: A base norm space, called the strong source space (which, however, in slight contrast to the setting of Alfsen and Shultz, is not 1-additive) and an order unit space, called the weak detector space, which is the norm and order dual space of Y. The last section of part I contains the guiding example suggested by orthodox quantum mechanics. We observe that our axioms are satisfied in this example. In the second part of this work (which will appear in the next issue of this journal) we shall postulate three further axioms and derive the JB-algebra structure of quantum mechanics. (shrink)

The present paper comprises Sects. 5–8 of a work which proposes an axiomatic approach to quantum mechanics in which the concept of a filter is the central primitive concept. Having layed down the foundations in the first part of this work (which appeared in the last issue of this journal and comprises Sects. 0–4), we arrived at a dual pair 〈Y, M〉 consisting of abase norm space Y and anorder unit space M, being in order and norm duality with respect (...) to each other. This is precisely the setting of noncommutative spectral theory, a theory which has been developed during the late nineteen seventies by Alfsen and Shultz. (2,3) In this part we add to the four axioms (Axioms S, DP, R, SP) of Sect. 3 three further axioms (Axioms E, O, L). These axioms are suggested by the work of Alfsen and Shultz and enable us to derive the JB-algebra structure of quantum mechanics (cf. Theorem 8.9). (shrink)

Beherrschten vor 20 Jahren noch Industriekonglomerate, Energiekonzerne und Banken die Rangliste der wertvollsten Unternehmen, wurden diese längst von Internetgiganten wie Google, Apple, Amazon und Tencent abgelöst. Digitale Technik ist allgegenwärtig: Wir tragen Hochleistungsrechner in unseren Taschen herum, Waschmaschinen können sich mit dem Internet verbinden. Doch erschöpft sich darin das Neue am digitalen Kapitalismus? 0Philipp Staab beleuchtet den digitalen Kapitalismus aus unterschiedlichen Perspektiven, um ihn präziser auf den Begriff zu bringen. Er zeigt, wie digitale Überwachungs- und Bewertungspraktiken in immer mehr Bereiche (...) der Wirtschaft vordringen und dabei die soziale Ungleichheit verschärfen. Das Spezifische am digitalen Kapitalismus, so Staab, ist die Herausbildung 'proprietärer Märkte': Kam es früher darauf an, Dinge herzustellen und mit Gewinn zu verkaufen, geht es im Zeitalter der Unknappheit um das Eigentum an den Märkten selbst.

ÖZ “Tanzanya’da Leibzig Misyoner Cemiyeti Misyonerliği, Karşılaşılan Zorluklar ve Kullanılan Yöntemler” isimli makale “Tanzanya’da Misyonerlik Faaliyetler Lutheran Kilise Örneği” isimli yüksek lisans tezine dayanmaktadır. Makale, Lutheran misyonerliğinin Tanzanya’da faaliyetlerine nasıl başladıkları, ilerleme yöntemleri ve karşılaşılan güçlükleri anlama noktasında önem arz etmektedir. Makalede ana konuya odaklanmadan önce, Tanzanya hakkında genel bir bilgilendirme yapılmış, ardından Leibzig Misyon Cemiyeti’nin (LMS) faaliyetlerine nasıl başladığı, kronolojik bir şekilde açmış olduğu istasyonlar, bu istasyonlarda karşılaşmış olduğu zorluklar ve kullanılan yöntemler hakkında bilgi verilmiştir. Ayrıca, Tanzanya’da Lutheran misyoner (...) cemiyetlerinin, Tanzanya Evanjelik Lutheran Kilisesi (Tanzania Evangelical Lutheran Church in Tanzania) ELCT ile tek bir kilise çatı altında toplanması ele alınmıştır. Son olarak, ELCT’nin kabul etmiş olduğu ilkeler ve Martin Luther’in öğretilerinin Afrika’daki yansımaları üzerinde durulmuştur. Makale, sadece misyonerleri ve misyonerlik faaliyetlerini değil, ayrıca muhatap olunan ve yüzyıllardır sömürgeleştirilen Afrika halkını anlamamıza da yardımcı olmaktadır. Araştırma, Lutheran misyonerliğinin Tanzanya’da başlamış olduğu 19. yüzyıl sonu ve yoğunlaştığı 20. yüzyıl ile sınırlandırılmıştır. Otto von Bismarck’ın (1815-1898) katkılarıyla gerçekleşen Berlin Konferansı sayesinde, batılı ülkelerin bayrakları ile haçları da sömürge topraklarına girmiştir. Tanzanya'da Lutheran Misyon, Johann Ludwig Krapf (1810-1881) ve Johannes Rebmann'ın (1820-1876) CMS tarafından görevlendirilmeleri sonucu başlamıştır. LMS, CMS'den 1892 tarihinde görevi devralmıştır ve Machame, Mamba, Old Moshi, Pare, Meru'da faaliyet göstermiştir. Misyon faaliyetleri süresince, savaşlar, kıtlık ve salgın, çok eşlilik, sünnet uygulaması, tanrı anlayışı gibi birçok zorlukla karşılaşılmıştır. Zorluklar, onları ortadan kaldırmaya yardımcı olacak; eğitim, sağlık, bütüncül hizmet, ortak dil (lingua franca), Kutsal Kitap çevirileri, ev ziyaretleri, yerli yardımcılar ve yerlileştirme gibi yöntemleri de beraberinde getirmiştir. Tanzanya’da LMS dışında; Katolik Kutsal Ruh Babaları (Holy Ghost Father/ Spiritanlar), Katolik Beyaz Babalar (Peres Blancs), Katolik Benediktinler, Anglikan Kilise Misyon Topluluğu (Chuch Missionary Society) CMS, Anglikan Üniversitelerin Orta Afrika Misyonu (The Universities’ Mission to Central Africa) UMCA gibi misyon grupları mevcuttur. Tanzanya'da bulunan Lutheran Misyon toplulukları, Evanjelik Lüteriyen Kilisesi (ELCT) adı altında 1963 yılında tek bir çatı altında toplanmıştır. ELCT bugün 5,2 milyon üyesi ile Tanzanya nüfusu içinde hatırı sayılır bir yere sahiptir. Bu çalışmada, deskriptif yöntem kullanılmıştır. Ulaşılabilen tüm ilk kaynaklara inilerek Lutheran misyonerler ve Tanzanya hakkında bilgi verilmiştir. Çalışmada Türkçe kaynaklara yer verilmekle birlikte yabancı kaynak kullanımına ve misyon topluluklarının bilinen kısaltmalarının kullanılmasına önem gösterilmiştir. Anahtar Kelimeler; Tanzanya, Hıristiyanlık, Misyonerlik, Lutheranizm, Leipzig Misyon Cemiyeti. (shrink)

Justice, equality, and righteousness—these are some of our greatest moral convictions. Yet in times of social conflict, morals can become rigid, making religious war, ethnic cleansing, and political purges possible. Morality, therefore, can be viewed as pathology-a rhetorical, psychological, and social tool that is used and abused as a weapon. An expert on Eastern philosophies and social systems theory, Hans-Georg Moeller questions the perceived goodness of morality and those who claim morality is inherently positive. Critiquing the ethical "fanaticism" of (...) Western moralists, such as Immanuel Kant, Lawrence Kohlberg, John Rawls, and the utilitarians, Moeller points to the absurd fundamentalisms and impracticable prescriptions arising from definitions of good. Instead he advances a theory of "moral foolishness," or moral asceticism, extracted from the "amoral" philosophers of East Asia and such thinkers as Ludwig Wittgenstein and Niklas Luhmann. The moral fool doesn't understand why ethics are necessarily good, and he isn't convinced that the moral perspective is always positive. In this way he is like most people, and Moeller defends this foolishness against ethical pathologies that support the death penalty, just wars, and even Jerry Springer's crude moral theater. Comparing and contrasting the religious philosophies of Christianity, Daoism, and Zen Buddhism, Moeller presents a persuasive argument in favor of amorality. (shrink)

Introduces contemporary American philosophy of technology through six of its leading figures. The six American philosophers of technology whose work is profiled in this clear and concise introduction to the field—Albert Borgmann, Hubert Dreyfus, Andrew Feenberg, Donna Haraway, Don Ihde, and Langdon Winner—represent a new, empirical direction in the philosophical study of technology that has developed mainly in North America. In place of the grand philosophical schemes of the classical generation of European philosophers of technology, the contemporary American generation addresses (...) concrete technological practices and the co-evolution of technology and society in modern culture. Six Dutch philosophers associated with Twente University survey and critique the full scope and development of their American colleagues’ work, often illustrating shifts from earlier to more recent interests. Individual chapters focus on Borgmann’s engagement with technology and everyday life; Dreyfus’s work on the limits of artificial intelligence; Feenberg’s perspectives on the cultural and social possibilities opened by technologies; Haraway’s conception of the cyborg and its attendant blurring of boundaries; Ihde’s explorations of the place of technology in the lifeworld; and Winner’s fascination with the moral and political implications of modern technologies. American Philosophy of Technology offers an insightful and readable introduction to this new and distinctly American philosophical turn. Contributors are Hans Achterhuis, Philip Brey, René Munnik, Martijntje Smits, Pieter Tijmes, and Peter-Paul Verbeek. (shrink)
