The exploration of chemical periodicity over the past 250 years led to the development of the Periodic System of Elements and demonstrates the value of vague ideas that ignored early scientific anomalies and instead allowed for extended periods of normal science where new methodologies and concepts are developed. The basic chemical element provides this exploration with direction and explanation and has shown to be a central and historically adaptable concept for a theory of matter far from the reductionist frontier. This (...) is explored in the histories of Prout’s hypothesis, Döbereiner Triads, element inversions necessary when ordering chemical elements by atomic weights, and van den Broeck’s ad-hoc proposal to switch to nuclear charges instead. The development of more accurate methods to determine atomic weights, Rayleigh and Ramsey’s gas separation and analytical techniques, Moseley’s X-ray spectroscopy to identify chemical elements, and more recent accelerator-based cold fusion methods to create new elements at the end of the Periodic Table point to the importance of methodological development complementing conceptual advances. I propose to frame the crossover from physics to chemistry not as a loss of accuracy and precision but as an increased application of vague concepts such as similarity which permit classification. This approach provides epistemic flexibility to adapt to scientific anomalies and the continued growth of chemical compound space and rejects the Procrustean philosophy of reductionist physics. Furthermore, it establishes chemistry with its explanatory and operational autonomy epitomized by the periodic system of elements as a gateway to other experimental sciences. (shrink)

Abstract: Science and emerging technologies should not be predominantly tasked with furnishing us with more sustainable societies. Continuous short-term technological bail outs without taking into account the longer socio-cultural incubation times required to transition to ‘weakly sustainable’ economies squander valuable resources and time. Emerging technologies need to be deployed strategically to buy time in order to have extended political, social and ethical discussions about the root-causes of unsustainable economies and minimize social disruptions on the path towards global sustainability. Keywords: Nanoscience; (...) nanotechnology; expanded materials design space; dematerialization; sustainability; permanent resource crises . (shrink)

We argue that a semantics for counterfactual conditionals in terms of comparative overall similarity faces a formal limitation due to Arrow’s impossibility theorem from social choice theory. According to Lewis’s account, the truth-conditions for counterfactual conditionals are given in terms of the comparative overall similarity between possible worlds, which is in turn determined by various aspects of similarity between possible worlds. We argue that a function from aspects of similarity to overall similarity should satisfy certain plausible constraints while Arrow’s impossibility (...) theorem rules out that such a function satisfies all the constraints simultaneously. We argue that a way out of this impasse is to represent aspectual similarity in terms of ranking functions instead of representing it in a purely ordinal fashion. Further, we argue against the claim that the determination of overall similarity by aspects of similarity faces a difficulty in addition to the Arrovian limitation, namely the incommensurability of different aspects of similarity. The phenomena that have been cited as evidence for such incommensurability are best explained by ordinary vagueness. (shrink)

Microscopy allows us to observe objects we cannot see with our eyes alone. With a light microscope, we can distinguish objects at the scale of the wavelengths of visible light just under a micrometer. Around 1870 Ernst Abbe, who laid the foundation of modern optics, suggested that the resolution of a microscope would improve by using some yet-unknown radiation with shorter wavelengths than visible light, that is, below 390 nanometers (1 nm = 10−9 m). Electrons can have wavelengths near 1 (...) picometer (1 pm = 10−12 m) and should therefore allow atoms to be distinguished since they are typically at least a few hundred pm apart. In this oversimplified view, further decreasing the wavelength of the radiation should allow us to increase the resolution of electron microscopy even more. However, this can only be done by increasing the energy of the radiation, which would ultimately destroy the samples. Other factors also affect the resolution of electron microscopes, among them non-ideal imaging properties of electromagnetic lenses, which result in false images. It took more than half a century to understand and control these aberrations and separate objects less than 1 Ångstrom (1 Å = 10−10 m) apart. (shrink)

After introducing the concept of compressed sensing as a complementary measurement mode to the classical Shannon-Nyquist approach, I discuss some of the drivers, potential challenges and obstacles to its implementation. I end with a speculative attempt to embed compressed sensing as an enabling methodology within the emergence of data-driven discovery. As a consequence I predict the growth of non-nomological sciences where heuristic correlations will find applications but often bypass conventional pure basic and use-inspired basic research stages due to the lack (...) of verifiable hypotheses.

The role of speed in innovations needs to be explored more thoroughly. I advocate here that for innovations which rely on scarce materials, research into more abundant substitutes needs to be accelerated while a regulatory-driven extension of the product life should slow down the number of incremental innovations and reduce our overall footprint on scarce resources. Chemical elements need to be established as global commons whose overuse can be regulated if required. Part of the efficiency gains of innovations could be (...) used for research to offset the ‘rebound effect’ and provide the public with a return on early infrastructure investments. (shrink)

The seed system is a major component of traditional management of crop genetic diversity in developing countries. Seed flows are an important part of this system. They have been poorly studied for minor Andean crops, especially those that are propagated vegetatively. We examine the seed exchanges of Oxalis tuberosa Mol., a vegetatively propagated crop capable of sexual reproduction. We studied the seed exchanges of four rural communities in Candelaria district at the international and local levels, emphasizing the spread of new (...) sexually-produced genotypes through these exchanges. Interviews with 44 farmers generated socioeconomic, agronomic, crop diversity and seed exchange information, and data on the potential incorporation of new sexually-produced genotypes in the crop germplasm. We interviewed merchants to evaluate the input and output of genetic diversity in the communities studied. Results showed a positive effect of the farmers’ wealth on the diversity cultivated and on seed exchanges. Most seed exchanges occurred at market, creating a distinction between cash and self-consumption landraces. Cash landraces were intensively exchanged; self-consumption landraces were isolated at the farmer level and prone to genetic drift and complete loss. Merchants exported seeds of cash landraces across Bolivia and into Peru and Argentina. New sexually produced genotypes are less incorporated into cash landraces than in self-consumed landraces. However, new genotypes incorporated into cash landraces are diffused faster and better, being more intensively exchanged. We propose conservation strategies that can be applied to other vegetatively propagated and minor Andean crops. (shrink)

Franz Brentano gilt als einer der einflussreichsten Philosophen an der Wende vom 19. zum 20. Jahrhundert. Dennoch sind die Philosophiehistoriker noch zu keinem endgültigen Urteil über seine Bedeutung gelangt. Der Grund hierfür ist vor allem darin zu suchen, dass Brentanos Werk bis heute nur unzureichend zugänglich ist, was vor allem daran liegt, dass der größte Teil davon nur in handschriftlicher Form existiert: Nach seinem unvollendet gebliebenen Hauptwerk, der Psychologie vom empirischen Standpunkt, hat Brentano keine größere Arbeit mehr veröffentlicht. Im (...) ersten Teil analysiert Binder die Gründe für Brentanos zurückhaltende Publikationstätigkeit, wobei einerseits der konfliktbehaftete biographische Hintergrund und die komplexe Persönlichkeit des Philosophen, andererseits theoretische Probleme, eine psychologische Einheitswissenschaft zu formulieren, die ihn an der Fertigstellung seines Hauptwerks scheitern ließen, im Vordergrund stehen. Im zweiten Teil verfolgt der Autor die wechselhafte Geschichte von Brentanos philosophischem Nachlass, die ihrerseits die Rezeption seiner philosophischen Theorien stark behindert hat. (shrink)

This paper presents the Spanish translation of the only two texts of Franz Brentano which deal specifically with St. Thomas Aquinas. The first text is a section about St. Albert the Great and Aquinas in an article published during Brentano’s youth, “The History of Ecclesiastical Sciences” (1867). The second text is an article, “Thomas Aquinas” (1908), written at the end of his life. Both texts reveal the immense value that Brentano saw in Aquinas. They also show that (...) he regarded Aquinas mainly as an important interpreter of Aristotle rather than as a philosopher in his own right. Brentano’s approach here also gives us some insight into his own conception of philosophical hermeneutics. The differences between the two texts are evident; for instance, in the second one, there is a Brentano’s manipulation of Aquinas’ thought to justify his leaving the Catholic Faith. The texts are also preceded by a little introduction of mine. Original titles: «Geschichte der kirchlichen Wissenschaften», in: Johann Adam Möhler (ed.), 'Kirchengeschichte', Band 2 (Regensburg: Manz, 1867), pp. 550-556 and «Thomas von Aquin», 'Neue Freie Presse' 15683 (18/4/1908): 1-5.

The edition illustrates the correspondence between Martin Buber and Ludwig Feuchtwanger and is based on four unpublished letters from the Leo Baeck Institute and the National Library Jerusalem. Among the documents included, Feuchtwanger's review of Buber's book on the origins and historical dynamic of messianism clarifies different aspects of the historical context as does the previously unknown letter from Franz Rosenzweig addressed to Ludwig Feuchtwanger.

Cet ouvrage cherche à mettre en lumière et reconstituer une manière antique négligée d’analyser la connaissance que l’auteure désigne comme « socratique » (p. 3), comme « pyrrhonienne » (p. 184) ou comme une « lecture sceptique de Platon », et dont elle trouve et analyse les principaux éléments chez Platon, Sextus Empiricus et les stoïciens. Cette lignée est définie comme liant immédiatement les questions épistémologiques à des questions normatives à propos de notre incapa­cité d’examiner nos...

Ce premier tome de Essais et conférences de Franz Brentano comporte seize études qui, pour la plupart, paraissent pour la première fois en traduction française. Ces textes sont regroupés dans quatre sections qui portent respectivement sur l'état de la philosophie et ses principes, sa philosophie de l'histoire et sa théorie des quatre phases, ses réflexions sur les philosophes Auguste Comte, Plotin, Schelling et Thomas d'Aquin, et finalement son débat avec Édouard Zeller, l'auteur de La philosophie des Grecs, autour (...) de l'interprétation de la philosophie d'Aristote. Ce volume comprend en outre une introduction substantielle visant à contextualiser chacune des contributions du philosophe viennois. (shrink)

Le texte traduit ici est tiré d’un recueil réunissant plusieurs écrits du philosophe allemand Franz Brentano (1838-1917) et publié en 1925 par son disciple Alfred Kastil sous le titre Essai sur la connaissance. La pièce maîtresse du recueil est un manuscrit de Brentano intitulé « À bas les préjugés ! », portant le sous-titre : « Une exhortation pour inciter l’époque actuelle à renoncer, dans l’esprit de Bacon et de Descartes, à tous les a priori aveugles » (1903). Nous (...) avons traduit la première partie de ce texte, dans laquelle Brentano s’attaque simultanément au common sense du philosophe écossais Thomas Reid et aux jugements synthétiques a priori d’Immanuel Kant. Cet extrait constitue l’un des rares documents dans lesquels Brentano expose sans détours son opposition radicale à un certain kantisme et, plus largement, à toute forme de constructivisme. Brentano s'attaque à l'idée kantienne du synthétique a priori, en jetant les bases d'un programme gnoséologique dont l'axe central est l'exhibition des sources empiriques de nos concepts fondamentaux (substance, cause, être, nécessité, etc.). Ce programme sera développé à son tour par Carl Stumpf ('Erkenntnislehre', 1939). (shrink)

Zusammenfassung: In Abschnitt (1) dieses Aufsatzes diskutiere ich Rawls’ theologische Kritik des Verdienstes in seiner frühen Schrift Über Sünde, Glaube und Religion. Im Gegensatz zur Theorie der Gerechtigkeit kritisiert der frühe Rawls eine Berufung auf das eigene Verdienst nicht als kognitiven Irrtum oder moralische Willkür, sondern sieht darin den sündhaften Ausdruck menschlichen Stolzes. Diese Kritik des Stolzes beruht auf einem schöpfungstheologischen Argument und mündet in ein Plädoyer für religiöse Demut. Abschnitt (2) zeigt, dass Rawls’ Diskussion von Verteilungsgrundsätzen in den übergreifenden (...) Versuch einer gerechtigkeitstheoretischen Zähmung des Zufalls eingebettet ist. Rawls entwickelt in der Theorie der Gerechtigkeit eine bestimmte Typologie des Zufalls und diskutiert, wie die vier von ihm diskutierten Lesarten des zweiten Grundsatzes der Gerechtigkeit auf den Zufall reagieren. Die gerechtigkeitstheoretische Zähmung des Zufalls distanziert sich sowohl von der Dystopie einer völligen Eliminierung des Zufalls als auch von einer fatalistischen Affirmation des Zufalls. In Abschnitt (3) erläutere ich zunächst die unterschiedlichen Begriffe des Verdienstes, welche Rawls in der Theorie der Gerechtigkeit vorstellt. Ich versuche Rawls’ Kritik des Verdienstes zu klären, indem ich diese gegen ein Missverständnis in Schutz nehme, welches Samuel Schefflers und Thomas Scanlons Interpretationen kennzeichnet. Schließlich beschäftige ich mich mit Robert Nozicks Suche nach dem „positive argument“ von Rawls’ Kritik des Verdienstes, komme dabei jedoch zu einem ganz anderen Ergebnis als Nozick. Meiner Meinung findet sich das „positive argument“, nach dem Nozick vergeblich sucht, nicht in der Theorie der Gerechtigkeit, sondern verdankt sich dem kreatürlichen Egalitarismus von Rawls’ theologischer Frühschrift.

A NUMBER of things are immediately striking about Roderick Chisholm’s way of doing philosophy. He is an analytic philosopher who is quite ready to cite at some length such diverse thinkers as Thomas Aquinas, Franz Brentano, Alexius Meinong, and Edmund Husserl. He unabashedly calls much of his work "metaphysical." His sources and conclusions mark him as something of a maverick, but his philosophical style is quintessential contemporary American establishment. These crosscurrents seem at least potentially exciting. They promise a (...) richness of perspective as well as exactness and clarity in argument. It has become commonplace to deplore the lack of dialogue among the main philosophical "schools" of this century—the analysts, the phenomenologists, etc. In Roderick Chisholm America has produced a philosopher who has consistently refused isolationism even when it has seemed hopelessly fashionable.

Die Musik in den christlichen Gottesdiensten hat die Menschen zu allen Zeiten fasziniert und sie in Tiefen erreicht, die dem gesprochenen Wort verwehrt bleibt. Das II. Vatikanische Konzil hat diese Bedeutung der liturgischen Musik erkannt und ihren hohen Wert beschrieben. In der Fortführung dieser grundsätzlichen Würdigung stellt sich die vorliegende Arbeit den grundlegenden theologischen, spirituellen, und ästhetischen Fragen geeigneter gottesdienstlicher Musik. Im Gespräch mit der Religionsphilosophie Franz Rosenzweigs eröffnet sich nicht nur ein Blick in die Faszination jüdischen Denkens, gleichzeitig (...) werden die gemeinsamen liturgischen Wurzeln von Judentum und Christentum bewusst. Auf diesem Hintergrund können Kriterien entwickelt werden, die der Diskussion um eine angemessene, menschenzugewandte und traditionsverbundene Musik im Gottesdienst wertvolle Hilfe geben. (shrink)

Dengan umur hampir dua ribu tahun Gereja Katolik merupakan lembaga paling tua yang mempertahankan diri melalui sejarah. Bagi Gereja Katolik sejarah itu penuh makna. Karena dalam perjalanannya melalui 20 abad eksisten-sinya Gereja Katolik mendapat bentuk serta pengertian diri yang sekarang. Maka sudah tepatlah kalau Norman Tanner, seorang imam Yesuit dan guru besar sejarah Gereja pada Universitas Gregoriana di Roma, dengan mendasarkan diri pada hasil penelitian sejarah Gereja yang berlimpah dalam 40 tahun terakhir, menulis sebuah “Sejarah Pendek Baru Gereja Katolik.” Hanya (...) dengan 260 halaman pembaca diantar secara kompeten menapaki 2000 tahun perjalanan Gereja Katolik. Gereja Katolik selalu menegaskan bahwa Kitab Suci hanya dapat dimengerti dalam ketertanaman dalam sebuah tradisi. Sebagaimana ditegaskan Tanner, “tradisi memegang peran normatif.” Pengertian tentang hakikat Kekristenan berkembang melalui sejarah. Gereja Katolik yakin “bahwa Kitab Suci harus disertai oleh suatu kesadaran tentang bagaimana pesannya dihayati dan dimengerti melalui berabad-abad lamanya, oleh suatu rasa bagaimana isi Kitab Suci dijernihkan oleh ajaran pihak-pihak berwenang dalam Gereja maupun melalui hidup, sembahyang, studi dan perjuangan umat Kristiani.” Karena itu, Gereja Katolik sekarang tidak dapat dimengerti kalau sejarahnya tidak dimengerti. Tanner membagi sejarah Gereja ke dalam lima tahap. Tahap pertama mencakup 300 tahun pertama di mana Gereja keluar dari dua setengah abad usaha penindasan dan penganiayaan oleh pemerintah kekaisaran Romawi, dan akhirnya menjadi agama resmi. Tahap kedua mulai dengan berakhirnya kekaisaran Romawi bagian Barat pada abad ke-5 dan sampai pada 1054 di mana perpecahan tragis antara Gereja Timur, Gereja-gereja Ortodoks, dan Gereja Barat—Gereja Katolik-Roma—menjadi resmi dan definitif. Perpecahan tersebut masih berlangsung sampai hari ini......................................... Yang khas dari buku Tanner adalah bahwa uraian tidak dibatasi pada kejadian-kejadian sekitar Gereja resmi: Konsili-konsili, Paus-paus yang penting, peristiwa-peristiwa dengan dampak historis seperti perpecahan antara Gereja Barat dan Gereja Timur atau Reformasi Protestan. Dalam buku ini juga dibicarakan ordo-ordo dan gerakan-gerakan religius, teolog-teolog penting, keagamaan rakyat, perkembangan-perkembangan intelektual, perkembangan dalam liturgi, doa dan mistik. Juga dibahas mengenai senirupa, arsitektur dan musik, bahkan sikap Thomas Aquinas terhadap liburan, olah raga dan entertainment. Kehidupan Katolik di basis pun ikut diceriterakan. Buku ini memberikan suatu tinjauan yang kaya dan berbobot tentang 2000 tahun kehidupan Gereja Katolik; bisa juga dikatakan, tentang perkembangan dari Kristianitas ke Gereja Katolik sekarang, dalam bahasa yang mudah diikuti dan dengan gaya naratif yang enak dibaca. Sebuah buku yang dapat sangat direkomendasikan bagi siapa saja yang ingin mendapat pengertian ringkas, tetapi cukup mendalam, tentang bagaimana Gereja Katolik menjadi Gereja Katolik.

What are virtue and vice, and how do they relate to other moral properties such as goodness and rightness? This book defends a perfectionist account of virtue and vice that gives distinctive answers to these questions. The account treats the virtues as higher‐level intrinsic goods, ones that involve morally appropriate attitudes to other, independent goods and evils. Virtue by itself makes a person's life better, but in a way that depends on the goodness of other things. This account was accepted (...) by many early twentieth‐ century consequentialists, including Franz Brentano, G. E. Moore, Hastings Rashdall, and W. D. Ross. The book elaborates it further than has been done before, describing its mathematical structure, connecting it to individual virtues and vices, and applying it to specific issues such as the morality of fantasy and the proper roles of private charity and the welfare state. While doing so, it argues for the account's superiority over rival views of virtue, including those defended under the heading of “virtue ethics.”. (shrink)
