ZusammenfassungBei der Programmierung der Rechenautomaten ist es Brauch, den Gedankengang mit Skizzen zu begleiten and dadurch an‐schaulich zu machen. Durch Graphschemata können auch zahlentheore‐tische Funktionen definiert werden. Kaluẑnin stellte die Aufgabe, die derart definierten zahlentheoretischen Funktionen je nach der Kompliziert‐heit der betreffenden Graphschemata in Klassen zu teilen. Es war zuvermuten, dass man auf diese Weise konstruktive Zwischenstufen zwischen den bekannten speziell‐rekursiven Funktionen und den allgemein‐rekursiven Funktionen erhaält. Die vorliegende Arbeit zeigt, dass dieser Weg nicht gangbar ist, da sich jede allgemein‐rekursive (...) Funktion durch Graphschemata von ähnlicher Struktur definieren lässt. (shrink)

The Hermotimus is Lucian’s longest piece of writing, surpassing even the two books of the True Tales, and at the same time his most successful effort to recreate the style and atmosphere of a Platonic dialogue, filled with a new—and for Lucian uncharacteristically serious—content, namely a sustained attack on “dogmatic” philosophical schools (the “haireseis” of its subtitle) and, inversely, a ringing endorsement of the tenets of Pyrrhonian Scepticism....

Anzeige für das Litterarische Centralblatt, von E. Rohde.--Anzeige in der Norddeutschen Allgemeinen Zeitung vom 26. Mai 1872, von E. Rohde.--Zukunftsphilologie! Von U. von Wilamowitz-Möllendorff.--An Friedrich Nietzsche, von R. Wagner.--Afterphilologie, von E. Rohde.--Zukunftsphilologie! Von U. von Wilamowitz-Möllendorff.

Ulrich von Wilamowitz-Moellendorff was one of the most prominent German philologists of his time and his work is still well regarded. This book, originally published in 1893, is a detailed analysis of the The Constitution of the Athenians, then usually regarded as a work of Aristotle. Wilamowitz accepts Aristotle's authorship of the famous treatise on the history of the constitution that restored democracy after the oligarchy of the Thirty. In Volume 1, he investigates the historical sources employed by Aristotle, hypothesising (...) that he was using at least two now lost works in addition to Herodotus and Thucydides, and that these were likely to be semi-official, contemporary chronicles of events in the city.

Much of what we believe we know, we know through the testimony of others. While there has been long-standing evidence that people are sensitive to the characteristics of the sources of testimony, for example in the context of persuasion, researchers have only recently begun to explore the wider implications of source reliability considerations for the nature of our beliefs. Likewise, much remains to be established concerning what factors influence source reliability. In this paper, we examine, both theoretically and empirically, the (...) implications of using message content as a cue to source reliability. We present a set of experiments examining the relationship between source information and message content in people's responses to simple communications. The results show that people spontaneously revise their beliefs in the reliability of the source on the basis of the expectedness of a source's claim and, conversely, adjust message impact by perceived reliability; hence source reliability and message content have a bi-directional relationship. The implications are discussed for a variety of psychological, philosophical and political issues such as belief polarization and dual-route models of persuasion. (shrink)

This article addresses the ability of Parallel Distributed Processing (PDP) networks to generate stagewise cognitive development in accordance with Piaget's theory of cognitive epigenesis. We carried out a replication study of the simulation experiments by McClelland (1989) and McClelland and Jenkins (1991) in which a PDP network learns to solve balance scale problems. In objective tests motivated from catastrophe theory, a mathematical theory of transitions in epigenetical systems, no evidence for stage transitions in network performance was found. It is concluded (...) that PDP networks lack the ability to recover the positive outcomes of analogous catastrophe analyses of real cognitive developmental data. In an attempt to further characterize the learning behaviour of PDP networks, we carried out a second simulation study using the discrimination‐shift paradigm. The results thus obtained indicate that PDP learning is compatible with the learning of stimulus‐response relationships, not with the acquisition of mediating rules such as conceived in (neo‐)Piagetian theory. In closing, we speculate about the feasibility of simulating stagewise development with alternative network architectures. (shrink)

First published in 1998, this volume why and how genetic engineering has emerged as the technology most likely to change our lives, for better or worse, in the opening century of the third millennium. Over twenty international experts, including moral philosophers and social scientists, describe the issues and controversies surrounding modern biotechnology and genetic engineering. They explore ways in which lay individuals and groups can join in an effective and constructive dialogue with scientists and industrialists over the assessment, exploitation and (...) safe management of these new and important technologies. Topics covered include a discussion of the issues surrounding 'Dolly', the cloned sheep, the politics and ethics of the international research programme to sequence the entire human genome, the ethical questions raised by the creation of transgenic farm animals, the morality of genetic experimentation on animals, the controversy surrounding the patenting of genetic material and of the transgenic animals themselves, the ethical implications of engineering animals for transplanting their organs into humans, and the environmental hazards of releasing genetically engineered organisms.

Von Hippel & Trivers (VH&T) interpret belief in God and belief in strong government as the outcome of an active process of self-deception on a worldwide scale. We propose, instead, that these beliefs might simply be a passive spin-off of efficient cognitive processes.

Recent experimental work suggests that the concept of contextual fields should be generalized to allow the modulation of local information extraction by both external and internal context. The external context relates to the coherent information of the stimulus; the internal context refers to the parts of this information which are relevant for behavior. This dual interaction, present at every level of the hierarchy, requires a fundamental unit of processing more complex than a single neuron appears today. We argue that the (...) cortical column supplies the required mechanisms for a separate top-down and bottom-up processing and allows for interaction without destructive cross-talk. This flexibility might explain why the same basic architecture of a cortical column is used in the whole isocortex. (shrink)

Voegelin's magisterial account of medieval political thought opens with a survey of the structure of the period and continues with an analysis of the Germanic invasions, the fall of Rome, and the rise of empire and monastic Christianity. The political implications of Christianity and philosophy in the period are elaborated in chapters devoted to John of Salisbury, Joachim of Flora, Frederick II, Siger de Brabant, Francis of Assisi, Roman law, and climaxing in a remarkable study of Saint Thomas Aquinas's mighty (...) thirteenth-century synthesis. Although _History of Political Ideas_ was begun as a textbook for Macmillan, Voegelin never intended it to be a conventional chronological account. He sought instead an original comprehensive interpretation, founded on primary materials and taking into account the most advanced specialist scholarship—or science as he called it—available to him. Because of this, the book grew well beyond the confines of an easily marketable college survey and until now remained unpublished. In the process of writing it, Voegelin himself outgrew the conceptual frame of a "History of Political Ideas," turning to compose _Order and History_ and the other works of his maturity. _History of Political Ideas_ became the ordered collection of materials from which much of Voegelin's later theoretical elaboration grew, structured in a manner that reveals the conceptual intimations of his later thought. As such, it provides an unparalleled opportunity to observe the working methods and the intellectual evolution of one of our century's leading political thinkers. In its embracing scope, _History of Political Ideas_ contains both analyses of themes Voegelin developed in his later works and discussions of authors and ideas to which he did not return or which he later approached from a different angle and with a different emphasis. _The Middle Ages to Aquinas_ has withstood the test of time. What makes it still highly valuable is its thoroughly revisionist approach, cutting through all the convenient clichés and generalizations and seeking to establish the experiential underpinnings that typified the medieval period.
