In dieser Untersuchung wird die Instandhaltung technischer Artefakte, neben deren Schaffung und Nutzung die dritte grundlegende Form technischen Handelns, als Teilthema der Technikphilosophie systematisch und umfassend analysiert. Nur durch Instandhaltung können die unermeßlichen und vielfältigen mittels technischer Verfahren erzeugten Werte vor vorzeitigem Verfall und Untergang bewahrt werden. Die Studie erschließt Instandhaltung in phänomenologischer (Grundlagen) und normativer Hinsicht (Instandhaltung und Gesellschaft). Die auf Unumkehrbarkeit des Handelns und ganz allgemein des Geschehens gegründete Endlichkeit seiner Dauer bindet das individuelle technische Artefakt als wesentliches (...) Element in den Verlauf der Allgemein-, Technik-, Kultur-, Wirtschafts- und Sozialgeschichte ein. (shrink)

A trusted guide into the inner realm where our spirits find strength to master life and live for God. It is hard to exaggerate the significance of Innerland, either for Eberhard Arnold or his readers. It absorbed his energies off and on for most of his adult life--from World War I, when he published the first chapter under the title War: A Call to Inwardness, to 1935, the last year of his life. Packed in metal boxes and buried at (...) night for safekeeping from the Nazis, who raided the author_s study a year before his death (and again a year after it), Innerland was not openly critical of Hitler_s regime. Nevertheless, it attacked the spirits that animated German society: its murderous strains of racism and bigotry, its heady nationalistic fervor, its mindless mass hysteria, and its vulgar materialism. In this sense Innerland stands as starkly opposed to the zeitgeist of our own day as to that of the author_s. At a glance, the focus of Innerland seems to be the cultivation of the spiritual life as an end in itself. Nothing could be more misleading. In fact, to Eberhard Arnold the very thought of encouraging the sort of selfish solitude whereby people seek their own private peace by shutting out the noise and rush of public life around them is anathema. He writes in The Inner Life:_These are times of distress. We cannot retreat, willfully blind to the overwhelming urgency of the tasks pressing on society. We cannot look for inner detachment in an inner and outer isolation...The only justification for withdrawing into the inner self to escape today's confusing, hectic whirl would be that fruitfulness is enriched by it. It is a question of gaining within, through unity with eternal powers, a strength of character ready to be tested in the stream of the world._ Innerland, then, calls us not to passivity, but to action. It invites us to discover the abundance of a life lived for God. It opens our eyes to the possibilities of that _inner land of the invisible where our spirit can find the roots of its strength and thus enable us to press on to the mastery of life we are called to by God._ Only there, says Eberhard Arnold, can our life be placed under the illuminating light of the eternal and seen for what it is. Only there will we find the clarity of vision we need to win the daily battle that is life, and the inner anchor without which we will lose our moorings. (shrink)

La cessation hebdomadaire du travail le dimanche est de plus en plus contestée dans notre société. Si les exigences économiques rendent nécessaire le fonctionnement ininterrompu des machines, il faudrait assurer à chaque employé un autre jour de repos. Peut-on alors définir le dimanche comme jour de repos commun à la majorité de la société ? Les chrétiens ont l’habitude de se prononcer en faveur du repos dominical en rappelant le commandement du Décalogue : «Observe le jour du sabbat ». Or (...) cet argument n’est pas pertinent pour des raisons historiques et herméneutiques. Il est toutefois possible de tirer de ce commandement, en particulier de sa version deutéronomique (Dt 5,12-15), des arguments susceptibles d’enrichir les débats d’aujourd’hui. (shrink)

Darwin proposed that evolutionary novelties are environmentally induced in organisms “constitutionally” sensitive to environmental change, with selection effective owing to the inheritance of constitutional responses. A molecular theory of inheritance, pangenesis , explained the cross‐generational transmission of environmentally induced traits, as required for evolution by natural selection. The twentieth‐century evolutionary synthesis featured mutation as the source of novelty, neglecting the role of environmental induction. But current knowledge of environmentally sensitive gene expression, combined with the idea of genetic accommodation of mutationally (...) and environmentally induced change, supports a revival of Darwin's original theory that is consistent with modern molecular and population genetics. †To contact the author, please write to: Smithsonian Tropical Research Institute, c/o Escuela de Biología, Universidad de Costa Rica, Costa Rica; e‐mail: [email protected].
