1. The Aim of This Essay Ethical Egoism, the doctrine that, roughly speaking, one should promote one's own good, has been a live issue since the very beginnings of moral philosophy. Historically, it is the most widely held normative theory, and, next to Utilitarianism, it is the most intensely debated one. What is at stake in this debate is a fundamental question of ethics: 'Is there any reason, except self-interest, for considering the interests of other people?' The ethical egoist answers No to this question, thus rejecting the received conception of morality. Is Ethical Egoism an acceptable position? There are many forms of Ethical Egoism, and each may be interpreted in several different ways. So the relevant question is rather, 'Is there an acceptable version of Ethical It is the main aim of this essay to answer this question. This Egoism?' means that I will be confronted with many other controversial questions, for example, 'What is a moral principle?', 'Is value objective or subjec tive?', 'What is the nature of the self?' For the acceptability of most ver sions of Ethical Egoism, it has been alleged, depends on what answers are given to questions such as these. (I will show that in some of these cases there is in fact no such dependence. ) It is, of course, impossible to ad equately discuss all these questions within the compass of my essay.
This is the first of two volumes containing papers submitted by the invited speakers to the 11th International Congress of Logic, Methodology and Philosophy of Science, held in Cracow in 1999, under the auspices of the International Union of History and Philosophy of Science, Division of Logic, Methodology and Philosophy of Science. The invited speakers are the leading researchers and accordingly the book presents the current state of the intellectual discourse in the respective fields. The papers delivered at the congress were divided into 17 sections. Thus the structure of the volume corresponds to the very schedule of the congress. Volume one contains the opening lecture by Andrzej K. Wróblewski as well as invited papers in sections of Proof Theory, Model Theory, Recursion Theory, Axiomatic Set Theory, Logic and Computation, Logic, Language and Cognition, Methodology, Probability, Induction, and Decision Theory, Philosophy of Logic, Mathematics, and Computer Science, and Philosophy of the Physical Sciences.
Stig Kanger (1924-1988) made important contributions to logic and formal philosophy. Kanger's most original achievements were in the areas of general proof theory, the semantics of modal and deontic logic, and the logical analysis of the concept of rights. But he contributed significantly to action theory, preference logic and the theory of measurement as well. This is the second of two volumes dedicated to the work of Stig Kanger. The first volume is a complete collection of Kanger's philosophical papers. The present volume contains critical essays on the various aspects of Kanger's work as well as some biographical sketches. Lennart Åqvist, Jan Berg, Brian Chellas, Anatoli Degtyarev, Lars Gustafsson, Sören Halldén, Kaj Børge Hansen, Sven Ove Hansson, Risto Hilpinen, Jaakko Hintikka, Ghita Holmström-Hintikka, Lars Lindahl, Sten Lindström, Ingmar Pörn, Dag Prawitz, Wlodek Rabinowicz, Krister Segerberg, Amartya Sen, Sören Stenlund, Göran Sundholm, and Andrei Voronkov have contributed to this volume.
The general treatment of problems connected with the causal conditioning of phenomena has traditionally been the domain of philosophy, but when one examines the relationships taking place in the various fields, the study of such conditionings belongs to the empirical sciences. Sociology is no exception in that respect. In that discipline we note a certain paradox. Many problems connected with the causal conditioning of phenomena have been raised in sociology in relatively recent times, and that process marked its empirical or even so-called empiricist trend. That trend, labelled positivist, seems in this case to be in contradiction with a certain type of positivism. Those authors who describe positivism usually include the Humean tradition in its genealogy and, remembering Hume's criticism of the concept of cause, speak about positivism as about a trend which is inclined to treat lightly the study of causes and confines itself to the statements on co-occurrence of phenomena.
Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.
Quantifiers: Logics, Models and Computation is the first concentrated effort to give a systematic presentation of the main research results on the subject, since the modern concept was formulated in the late '50s and early '60s. The majority of the papers are in the nature of a handbook. All of them are self-contained, at various levels of difficulty. The Introduction surveys the main ideas and problems encountered in the logical investigation of quantifiers. The Prologue, written by Per Lindström, presents the early history of the concept of generalised quantifiers. The volume then continues with a series of papers surveying various research areas, particularly those that are of current interest. Together they provide introductions to the subject from the points of view of mathematics, linguistics, and theoretical computer science. The present volume has been prepared in parallel with Quantifiers: Logics, Models and Computation, Volume Two. Contributions, which contains a collection of research papers on the subject in areas that are too fresh to be summarised. The two volumes are complementary. For logicians, mathematicians, philosophers, linguists and computer scientists. Suitable as a text for advanced undergraduate and graduate specialised courses in logic.
Seit einem Jahrzehnt gibt es eine intensive Forschung zur »Radikalaufklärung« – dem atheistischen, skeptischen und materialistischen Flügel des Denkens im späten 17. und 18. Jahrhundert. Vor allem Jonathan Israel hat für die aufregende These argumentiert, dass diese radikalen Aufklärer verantwortlich sind für die Errungenschaften der Moderne, für Freiheit und Menschenrechte, Gleichheit und Toleranz, und dass der Spinozismus eine zentrale Rolle bei deren Durchsetzung gespielt hat. In diesem Band setzen sich acht führende nationale und internationale Experten mit Israels These auseinander und zeigen die Vielfalt und Deutungen der Radikalaufklärung auf. Mit Beiträgen von Silvia Berti, Wiep van Bunge, Margaret C. Jacob, Anthony McKenna u. a.
Dieses Hegels Buch stellt den Höhepunkt der philosophischen Entwicklung des deutschen Idealismus dar. Hegel beschreibt darin die Bildungsgeschichte des Bewusstseins und entfaltet programmatisch drei Stufen der Wissensbildung; Ausbildung der persönlichen Welterfahrung, individuelle Selbsterfahrung und Verständnis für die Geschichte.
