What is empiricism and what could it be? Bas . van Fraassen, one of the world’s foremost contributors to philosophical logic and the philosophy of science, here undertakes a fresh consideration of these questions and offers a program for renewal of the empiricist tradition. The empiricist tradition is not and could not be defined by common doctrines, but embodies a certain stance in philosophy, van Fraassen says. This stance is displayed first of all in a searing, recurrent critique of metaphysics, (...) and secondly in a focus on experience that requires a voluntarist view of belief and opinion. Van Fraassen focuses on the philosophical problems of scientific and conceptual revolutions and on the not unrelated ruptures between religious and secular ways of seeing or conceiving of ourselves. He explores what it is to be or not be secular and points the way toward a new relationship between secularism and science within philosophy. (shrink)

Die Allgemeine Erkenntnislehre gilt als das Hauptwerk von Moritz Schlick. Hierin entwickelt Schlick in Auseinandersetzung mit zeitgenössischen Positionen seine einflussreichen Gedanken zum Wesen der Erkenntnis, zum Verhältnis zwischen Psychologie und Logik, zum Leib-Seele-Problem und zum erkenntnistheoretischen Realismusstreit. Der Text wurde während der frühen Rostocker Jahre Schlicks, von 1911 bis 1916, verfasst. Die Allgemeine Erkenntnislehre ist ein Meilenstein der wissenschaftlichen Philosophie und grundlegend für die spätere Entwicklung des Wiener Kreises des Logischen Empirismus.

Considerable unclarity exists in the literature concerning the origin and authorship of Wissenschaftliche Weltauffassung. Der Wiener Kreis, the Vienna Circle’s manifesto of 1929 and on the extent of and the reasons for the mixed reception it received in the Circle itself. This paper reconsiders these matters on the light of so far insufªciently consulted documents.

Arne Dekke Eide Naess was born on January 27, 1912 in Oslo. After a long and successful life he passed away on January 12, 2009 in Oslo as the most renowned Norwegian philosopher, where he was honoured with a state funeral. He was one of the most important public figures in Norway and in his later years became known all over the world as a pioneer of the ecological movement. Given this publicity in recent decades his earlier life was forgotten (...) or obscured in a sense — especially his student years in Paris, Vienna and Oslo before the outbreak of World War II, when he attended the famous Vienna Circle around Moritz Schlick during a stay in Vienna 1934–36. Here he wrote his dissertation Erkenntnis und wissenschaftliches Verhalten which was published in Oslo by the Norwegian Academy of Science in 1936. (shrink)

The first volume of the Library of Living Philosophers (LLP) appeared in 1939, the brainchild of the late Professor Paul A. Schilpp. Schilpp saw that it would help to eliminate confusion and endless sterile disputes over interpretation if great philosophers could be confronted by their capable philosophical peers and asked to reply. As well as a number of critical essays with the chosen philosopher's replies to each essay, each volume would include an intellectual autobiography and an up-to-date bibliography The LLP (...) series has exceeded even Schilpp's expectations, enabling great philosophers to do more than clarify by extending and elaborating their thoughts. A volume in the Library of Living Philosophers is not merely a commentary on a philosopher's work; it is a critical part of that work. (shrink)

Es wird vorgeschlagen, einen Begriff „Lebenslage“ in den Sozialwissenschaften zu verwenden, der nicht nur „Wohnung“, „Nahrung“, „Kleidung“ und andere Teile des „Realeinkommens“ umfasst, sondern auch „Mortalität“, „Morbidität“ usw. Die gesamte „Lebensstimmung“ einer Person hängt von der Gesamtheit der Lebenslagenteile ab, von der Morbidität ebenso wie von der Wohnung. Ob man die Lebens-Stimmung in „positive“ und „negative“ Elemente zerlegen kann, die man einzelnen Elementen der Lebenslage zuordnet, ist eine offene Frage.Die wissenschaftliche Praxis geht am besten von „Lebenslagenphysiognomien“ (Lebenslagensilhouetten) aus, die durch (...) verschiedenartig gemessene und skalierte Grössen gebildet werden. Wenn man die Lebenslagen einzelner Personen oder ganzer Länder auch nicht stets „skalierend“ zu vergleichen vermag, so kann man sie doch immer beschreiben. Geht man daran, „Lebenslagenkataster“ (Lebenslageninventare) verschiedener Völker und Zeiten aufzustellen, so muss man beachten, dass die Lebensstimmung eines Menschen nicht etwa schon durch die Garten fläche gekennzeichnet wird, die ihm zur Verfügung steht ; man muss angeben, über wieviel Freizeit er verfügt, um die Gartenfläche zu benutzen.Man kann Gesellschaftsordnungen durch die von ihnen „produzierten“ Lebenslagen ln Verbindung mit einer umfassenden „Naturalrechnung“ kennzeichnen. Ob die Geldrechnung in gewissem Ausmass geeignet ist, die Naturalrechnung zu ersetzen, kann nur mit Hilfe der Naturalrechnung entschieden werden, innerhalb deren die Lebenslagenrechnung eine wesentliche Rolle spielt.On propose d'introduire dans les sciences sociales le concept de „situation de vie“, qui englobe non seulement logement, alimentation, vêtement et autres parties du revenu réel, mais aussi mortalité, morbidité, etc. Le „climat de vie“ d'une personne dépend de l'ensemble de sa „situation de vie“, de la morbidité aussi bien que du logement. Est-il possible de décomposer le „climat de vie“ en éléments „positifs“ et „négatifs“, qui correspondraient aux différents éléments de sa „situation de vie“? Réservons provisoirement la question.Si nous envisageons la méthode scientifique, le point de départ le meilleur serait la notion de „physiognomie (silhouette) de vie“. On les dessinerait à l'aide de grandeurs diversement mesurées et graduées.Certes, il ne serait guère possible de comparer les „situations de vie“ de personnes ou de peuples entiers en utilisant une seule échelle de graduation, tout au moins est-il possible de les décrire. Si l'on tente de dresser un „cadastre (inventaire) de situations de vie“ de différents peuples en différentes époques, il ne faut pas oublier que le „climat“ dans lequel vit un individu n'est pas assez déterminé par la surface du jardin qui lui appartient, il faut aussi préciser le loisir dont il dispose pour le cultiver.On peut caractériser les différents régimes sociaux par les situations de vie qu'ils produisent, à condition de combiner cette analyse avec un calcul en nature aussi étendu que possible. Le calcul en argent peut-il remplacer dans une certaine mesure le calcul en nature? La question elle-même ne peut être tranchée qu'à l’aide du calcul en nature qui lui-même dépend largement du calcul des „situations de vie“. (shrink)

Ecologically responsible policies are concerned only in part with pollution and resource depletion. There are deeper concerns which touch upon principles of diversity, complexity, autonomy, decentralization, symbiosis, egalitarianism, and classlessness.

The history of the Vienna Circle is bound up with what was called the Wissenschaftliche Weltauffassung. But with the requirements of the members when it came to deciding whether a sentence expressed scientific knowledge or not, the basic sentences expressing a Lebens- und Weltauffassung would scarcely qualify as such, nor would hypotheses about a scientific world view. The Wissenschaftlichkeit ofphysicalism, logical behaviorism,logical syntax, unity of science, were hypothetical at best, and in my opinion should not be identified with the total (...) philosophical enterprise of the Vienna Circle. To its strictly speaking philosophical enterprise I attribute a certain kind of scientific or research attitude and clarity as much as any set of philosophical opinion of a substantial sort.

In what follows I shall speak about many phenomena, but what I wish to convey more than anything else is a combination of positive aspects of the rightly famous seminar headed by Moritz Schlick the years before he was shot on the stairs of the University of Vienna in 1936. These aspects make the seminar unique. I have taken part in a wealth of good seminars before and after 1936, but my experience as a participant of that seminar makes it, (...) for me, stand out as unsurpassed. (shrink)

In 'the methodological character of theoretical concepts' carnap offered a sophisticated criterion of empirical significance. Unfortunately, Shortly thereafter david kaplan devised a pair of devastating counter-Examples which appeared to show that carnap's criterion was simultaneously too wide and too narrow. In this note I show that kaplan's first counter-Example misses its mark and that his second counter-Example can be avoided by a natural generalization of carnap's method.

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)
