The article investigates the interplay of moral rules in computer simulation. The investigation is based on two situations which are well-known to game theory: the prisoner''s dilemma and the game of Chicken. The prisoner''s dilemma can be taken to represent contractual situations, the game of Chicken represents a competitive situation on the one hand and the provision for a common good on the other. Unlike the rules usually used in game theory, each player knows the other''s strategy. In that way, (...) ever higher levels of reflection are reached reciprocally. Such strategies can be interpreted as moral rules.Artificial morality is related to the discipline of Artificial Life. As in artificial life, the use of genetic algorithms suggests itself. Rules of behaviour split and reunite as chromosome strings do. (shrink)

The following conjecture is due to Shelah–Hasson: Any infinite strongly NIP field is either real closed, algebraically closed, or admits a non‐trivial definable henselian valuation, in the language of rings. We specialise this conjecture to ordered fields in the language of ordered rings, which leads towards a systematic study of the class of strongly NIP almost real closed fields. As a result, we obtain a complete characterisation of this class.

Le portrait politique de Constant est divisé en quatre parties.

Modern science is based empirically on data, which are gained, mainly, by means of technical machinery and plants of high complexity. This type of laboratory research is at a distance to the old forms of investigating nature such that it is under suspicion to investigate artefacts rather than nature. - Against this it is argued in the following, that laboratory research has to be acknowledged as true heir of the form of science which Galileo had started. Knowledge of the powers (...) and mechanisms of nature can be gained only by means of pointed interventions into natural processes. The term ,,laboratory", however, designates less the place of experimentation, but, rather, the ,,thoughtstyle" practised by a research group, in which forms of handling experimental setups and (social) structures of cooperation in a team of specialists are integrated. - Scientific facts cannot be separated from the social and cultural conditions comprised in a thoughtstyle, they are dependent on thoughtstyles. Yet, this does not make them mere artefacts of instrumentation. Scientific practices in the laboratories define, rather, the conditions under which nature can present herself. German Die moderne Naturwissenschaft stützt sich auf empirische Daten, die weitgehend in hochkomplizierten technischen Apparaturen und Anlagen gewonnen werden. Von den Formen der alten Naturforschung ist diese Laborforschung so weit entfernt, daß sie den Vorwurf auf sich zog, sie untersuche Artefakte, aber nicht Natur. - Dagegen wird hier argumentiert, daß die Laborforschung als genuine Erbin der mit Galilei begonnenen Form der Naturwissenschaft anzuerkennen sei. Erkenntnis von den Wirkungsweisen der Natur ist nur durch gezieltes Eingreifen in Vorgänge der Natur zu gewinnen. Unter dem ,,Laboratorium haben wir allerdings weniger den Ort des Experimentierens zu verstehen, als vielmehr den in einer Arbeitsgruppe praktizierten ,,Denkstil, in dem die Formen des Forschungshandelns mit den (sozialen) Strukturen der arbeitsteiligen Kooperation verbunden sind. - Wissenschaftliche Tatsachen lassen sich zwar nicht von den Bindungen an einen Denkstil ablösen, sie erweisen sich als denkstilabhängig; das macht sie aber nicht zu Kunstprodukten. Die in einem Labor praktizierten Arbeitsweisen definieren vielmehr die Bedingungen, unter denen Natur sich zeigen kann. (shrink)

Gilt das Verbot der Tötung Unschuldiger absolut oder darf selbst diese fundamentale Moralnorm unter Ausnahmebedingungen verletzt werden? Wir leben in einer Welt voller Gefahren. Das Leben von Menschen wird bedroht durch verbrecherische Diktaturen, terroristische Anschläge, technische Havarien und Katastrophen verschiedener Art. Dürfen solche Gefahren notfalls auch dann bekämpft werden, wenn dabei Unschuldige getötet werden oder ihr Tod in Kauf genommen werden muss? Das Buch gibt eine moralphilosophische Antwort auf diese politisch, ethisch und rechtlich umstrittene Frage. Lothar Fritze analysiert das (...) Rechtsdogma der Nichtabwägungsfähigkeit menschlichen Lebens und fragt, wie sich das Verbot der Tötung Unschuldiger mit der verbreiteten moralischen Intuition vereinbaren lässt, wonach in Extremfällen durchaus einige wenige unschuldige Menschen geopfert werden dürfen, um sehr viele andere Unschuldige zu retten.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Writing and Authority in Early ChinaLothar von FalkenhausenWriting and Authority in Early China. By Mark Edward Lewis. Albany: State University of New York Press, 1999. Pp. vii + 544. Hardcover $92.50. Paper $31.95.Writing and Authority in Early China is a forceful and sparklingly original work in which Mark Edward Lewis explores the role of writing and texts in the transformation of political authority during the Warring States, Qin, (...) and Western Han periods. Following in the footsteps of the author's well-received first book1 and his magisterial contribution to the Cambridge History of Ancient China,2Writing and Authority establishes Lewis as the premier Western historian of the crucial centuries surrounding the unification of China under a centrally administered empire in 221 B.C. The book's complex, comprehensive, and coherent argument is informed by a variety of Western theoretical approaches, but it principally emanates from a close reading of the full record of transmitted texts and recently excavated manuscripts on [End Page 127] bamboo or wooden slips. The inclusion of the latter class of sources, beset with treacherous problems of decipherment, is still unusual in mainstream sinological scholarship and indicates the author's supreme confidence in his philological skills. With a firm hand, undaunted by the multifarious nature of his materials, Lewis guides the reader to some fundamental themes in recent sinology, opening manifold novel perspectives along the way. Even when dealing with well-known texts, he often proposes striking reinterpretations.In his Introduction, Lewis enumerates six main functions of writing in ancient China: enforcing state authority; creating text-based communities and "public spheres"; transcending the confines of space, time, and human mortality; fashioning figures of authority in the past; standardizing specialized technical terminology; and encrypting secret meanings. In Lewis' own words, "the culminating role of writing in the period, and the key to its importance in imperial China, was the creation of parallel realities within texts that claimed to depict the entire world" (p. 4). This ultimately led to the formation of the Confucian canon as a "textual double of the polity" that could survive cataclysmic changes of regimes.In chapter 1, "Writing the State," Lewis points out that before the Warring States period Chinese writing occurred exclusively in religious contexts. After circa 500 B.C., written documents gradually came to be used in the administration of government and trade. Both in their details of formulation and in the implication that anything committed to writing was thereby supernaturally validated, these new types of documents exhibit pervasive continuity with the earlier kinds of texts used in ritual communication with the ancestral spirits. Such continuity is also reflected in the rise of religious beliefs in a netherworld governed by a bureaucratic hierarchy and administrative processes parallel to those of the world of the living. According to Lewis, "the most important modification in the shift to an administrative polity [in the Warring States] was the extension of writing to new elements of the population. The attributes of the Zhou nobility... were transferred to the common people in the administrative documents of the new state. This widening range of inscription into the state order altered the social meaning of being recorded from a sign of power to one of subjection" (p. 13).Warring States rulers were cast in the role not of the authors of texts but of the authority behind them. Administrative and legal texts were concerned, ultimately, with the proper naming of phenomena, a process that had to adapt itself continually to the changes of the times. The authority of rulers came to encompass both human society and the natural world. "Whereas local and central administration were largely created through reworking and rewriting the ritual bases of the old Zhou order by means of a rationalizing cosmology, the re-invention of rulership drew on the contemporary religious realm and what is sometimes described as shamanism to provide images of cosmic power" (p. 42). Lewis illustrates the mechanics for applying these universal principles of rulership by a comprehensive analysis of the Zhou li (or Zhou guan), emphasizing the cosmological arrangement of the ideal government described therein and the dual administrative and religious dimensions of...

"Die Kritik ist nicht die Wissenschaft." Zu diesem Ergebnis führt eine Besinnung auf den Begriff der Objektivität in der kunstwissenschaftlichen Forschung. Die aktuelle Situation, die durch wissenschaftstheoretische und methodologische Überlegungen bestimmt ist, verlangt neue Zielsetzungen und Aufgaben. Das zentrale Problem - die Begründung der Ästhetik als selbständige, moderne Wissenschaft - steht und fällt mit der Frage, ob die Kunst Gegenstand einer generellen, empirisch prüfbaren Theorie sein kann. Der zeitgenössische Strukturalismus glaubt diese Frage positiv beantworten zu können. Er versucht, die ästhetischen (...) Gebilde nicht nur als registrierbare Einzelfälle zu erklären und zu bewerten, sondern auf allgemeinere Gesetzmäßigkeiten zurückzuführen. (shrink)
