Ever since Aristotle it has been accepted that there exists a combination of inductive and deductive reasoning and a sort of unified inductive-deductive methodology. If one analyzes the procedures and logic of scientific explanation and the methods of generating and justifying scientific knowledge, one recognizes the prototype of philosophy of science found in Aristotle’s inductive and deductive procedure that is described in his Posterior Analytics, Physics and Metaphysics, where heviewed scientific inquiry as a progression from observations to general principles and back to observation. He maintained that the scientist should induce explanatory principles from the phenomena to be explained, and then deduce statements about the phenomena from premisses which include these principles

The Vienna Circle as part of the intellectual movement of Central European philosophy of science is certainly one of the most important currents for the emergence of modern philosophy of science. Independent from this uncontested historical fact there remains the question of the direct and indirect infl uence, reception and topicality of this scientifi c community in contemporary general philosophy of science as well as in the philosophy of the individual sciences, including the social sciences and humanities

The Fifth International Congress for the Unity of Science took place at Harvard University from September 3 to September 9, 1939 in Cambridge, Massachusetts. It marked the end of the scientific community’s great forum dedicated to promoting the Encyclopedia of Unified Science,with some two hundred participants and 60 speakers. In spite of the outbreak of World War II, Otto Neurath’s International Institute for the Unity of Science had been able to organize the congress with the support of the American Association for the Advancement of Science,the American Philosophical Association, the Philosophy and Science Association, the History of Science Society and the Association for Symbolic Logic. The congress was opened by James B. Conant , P.W. Bridgman, Otto Neurath and Charles Morris. Due to the escalation of the war, the abstracts and contributions submitted at the beginning of the conference could not be published, as originally planned, in the ninth volume of Erkenntnis/Journal of Unified Science . Only ten of these, already published separately, were included in the reprint of the journal Erkenntnis. The remaining preprints mostly languished in Otto Neurath’s papers. We plan to print the most important of these so far unpublished contributions to the six sections of the Fifth International Congress for the Unity of Science in the coming Yearbooks

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

Im Rahmen der vorjährigen "Third International History of Philosophy of Science Conference” (HOPOS 2000) an der Universität Wien wurden die politische Bedeutung und der kulturelle Kontext der aus Wien stammenden, jedoch vertriebenen Wissenschaftsphilosophie in einem eigenen Programmschwerpunkt thematisiert. In je vier deutschsprachigen und englischsprachigen Beiträgen werden im vorliegenden Band die historische und politische Bedingtheit und Relevanz des Wiener Kreises bis zur Philosophy of Science im angloamerikanischen Raum behandelt. Somit wird die Entwicklung der Wissenschaftsphilosophie in Österreich (mit einem Blick auf Deutschland) von der Ersten zur Zweiten Republik bzw. die Wirkungsgeschichte dieser Emigrationswissenschaft vor allem in den USA aus gegenwärtiger Perspektive kritisch beleuchtet. Die Beiträge von u.a. Hans Joachim Dahms, Gernot Heiss, Don A. Howard und Alan Richardson zeigen, dass "Reine" Wissenschaftstheorie Teil eines gesellschaftlichen Systems ist und von dessen Pluralität und Toleranz lebt, aber auch immer einen Seismografen des kulturellen Klimas darstellt.

Constructibility and complexity play central roles in recent research in computer science, mathematics and physics. For example, scientists are investigating the complexity of computer programs, constructive proofs in mathematics and the randomness of physical processes. But there are different approaches to the explication of these concepts. This volume presents important research on the state of this discussion, especially as it refers to quantum mechanics. This `foundational debate' in computer science, mathematics and physics was already fully developed in 1930 in the Vienna Circle. A special section is devoted to its real founder Hans Hahn, referring to his contribution to the history and philosophy of science. The documentation section presents articles on the early Philipp Frank and on the Vienna Circle in exile. Reviews cover important recent literature on logical empiricism and related topics.

Scientific Philosophy: Origins and Development is the first Yearbook of the Vienna Circle Institute, which was founded in October 1991. The book contains original contributions to an international symposium which was the first public event to be organised by the Institute: `Vienna--Berlin--Prague: The Rise of Scientific Philosophy: The Centenaries of Rudolf Carnap, Hans Reichenbach and Edgar Zilsel.' The first section of the book - `Scientific Philosophy - Origins and Developments' reveals the extent of scientific communication in the inter-War years between these great metropolitan centres, as well as presenting systematic investigations into the relevance of the heritage of the Vienna Circle to contemporary research and philosophy. This section offers a new paradigm for scientific philosophy, one which contrasts with the historiographical received view of logical empiricism. Support for this re-evaluation is offered in the second section, which contains, for the first time in English translation, Gustav Bergmann's recollections of the Vienna Circle, and an historical study of political economist Wilhelm Neurath, Otto Neurath's father. The third section gives a report on current computer-based research which documents the relevance of Otto Neurath's `Vienna method of pictorial statistics', or `Isotypes'. A review section describes new publications on Neurath and the Vienna Circle, as well anthologies relevant to Viennese philosophy and its history, setting them in their wider cultural and political perspective. Finally, a description is given of the Vienna Circle Institute and its activities since its foundation, as well as of its plans for the future.
