Bas Van Fraassen Is ondertussen "het moderne", het idee dat er wetenschappelijke vooruitgang bestaat, door het "postmodernisme" geheel platgewalst? Dat lijkt niet het geval. De in Nederland geboren en in Canada werkende wetenschapsfilosoof Bas van Fraassen bij voorbeeld ontkent dat er überhaupt sprake is van een probleem. We hoeven helemaal niet te geloven dat de wereld in elkaar zit zoals de huidige theorieën zeggen. De accumulatie van wetenschappelijke kennis betreft uitsluitend en alleen de verschijnselen. Onverifieerbare beweringen zijn weliswaar geen betekenisloos gewauwel, alleen doen we er verstandig aan ze niet te geloven omdat dit geloof niet wetenschappelijk onderbouwd kan worden. Het doet er kortom niet toe dat de wetenschapsgeschiedenis (Kuhn, Feyerabend) ons leert dat de wereld volgens de volgende generatie theorieën weer totaal anders in elkaar zal zitten. In een kranteninterview legde Van Fraassen het als volgt uit: Het onderzoek binnen een onderzoekprogramma wordt verondersteld theoretische progressie op te leveren. Wetenschappelijke vooruitgang wordt dus niet bepaald door een toenemende empirische inhoud, zoals in het geval van de logisch empiristen, of een toenemende informatieve waarde, zoals in het geval van het falsificationistische programma van Popper; vooruitgang houdt in een toenemende voorspellende waarde. Een theorie is een waardig opvolger van de vorige theorie in het onderzoekprogramma wanneer ze alles wat de eerste theorie kon verklaren of voorspelde omvat, en bovendien voorspellingen doet die volgens de eerste theorie onvoorstelbaar zijn.

NUMBER: QUOTATION: To develop an empiricist account of science is to depict it as involving a search for truth only about the empirical world, about what is actual and observable.... It must involve throughout a resolute rejection of the demand for an explanation of the regularities in the observable course of nature, by means of truths concerning a reality beyond what is actual and observable, as a demand which plays no role in the scientific enterprise.

6. Bas Van Fraassen / Information Philosophie Im Internet bas van fraassen (*1941, Goes, Niederlande) gehört zu den bedeutendsten http://www.information-philosophie.de/philosophie/fraassen.html

Position Andreas Hüttemann: Bas van Fraassen Niederländischer Wissenschaftstheoretiker Bas van Fraassen (*1941, Goes, Niederlande) gehört zu den bedeutendsten Wissenschaftstheoretikern der Gegenwart. Es gelang ihm, ein empiristisches Verständnis der Wissenschaften zu artikulieren, das nicht denjenigen Einwänden ausgesetzt war, mit denen die empiristische Tradition im Anschluss an die Zeit des Wiener Kreises konfrontiert worden war. Van Fraassen hat 1966 in Pittsburgh bei Grünbaum mit der Arbeit Die Grundlagen einer kausalen Theorie der Zeit promoviert. Darin schloss er an die Theorien Reichenbachs und Grünbaums an und vertrat eine relationale Theorie der Raum-Zeit, derzufolge Raum und Zeit nicht als eigenständige Ge-genstände existieren. Vielmehr existieren allein einzelne physikalische Gegenstände, Er-eignisse und Prozesse, die in vielfältigen Be-ziehungen zueinander stehen und so eine komplexe relationale Struktur bilden, die wir in unseren Theorien als Raum und Zeit repräsentieren. Van Fraassens eigener Einschätzung zufolge hat sich seine Formulierung der empiristischen Position teils aus den Herausforderungen bei der Verteidigung dieser Raum-Zeit-Theorie ergeben. Eine weitere wichtige Quelle für seine spätere Position war seine Beschäftigung mit der Logik. Wesentliche begriffliche Werkzeuge, mithilfe derer er seinen Empirismus expliziert, wie z. B. den Modellbegriff, hat er ihrem Repertoire entnommen. Von seinen eigenen Arbeiten ist hier insbe-sondere seine einflussreiche Konzeption der "Supervaluation" zu erwähnen. Dabei handelt es sich um einen Beitrag zur sogenannten "freien Logik", einem Teil der Logik, in der auch Aussagen über nicht-existierende Dinge zugelassen sind. Die Supervaluation ist eine Methode, Aussagen, in denen singuläre Terme ohne Bezug auftreten (wie z. B. Pegasus oder der jetzige König von Frank-reich), Wahrheitswerte zuzuordnen.

Sola Experientia ? Feyerabend's Refutation of Classical Empiricism Philosophy of Science 64 (Proceedings): S385-S395 (1997) Bas C. van Fraassen Philosophy Department Princeton University Princeton, N.J. 08544 USA Feyerabend's "Classical Empiricism" (1970) draws on a 17th century Jesuit argument against Protestant fundamentalism. The argument is very general, and applies to any simple foundationalist epistemology. Feyerabend uses it against Classical Empiricism roughly, the view that what is to be believed is exactly what experience establishes, and no more which he identifies as among other things Newton's "dogmatic ideology". I will first examine the argument, then ask whether it is perhaps too powerful, a sceptical argument which, if cogent, undermines any pretense to rational belief. Feyerabend explains why the argument could have had little force in the targeted Protestant community. But that is significant only if we can think of its epistemic stance as rational. Feyerabend's irony leaves us with doubts, and yet, perhaps, also with some hope of a genuinely promising development. 1. The Jesuit Argument

Bas C. van Fraassen Brief Bio 1999-2000 Terry Lectureship Bas C. van Fraassen is one of the world’s foremost contributors to philosophical logic and the philosophy of science. In the latter field he is known for strongly empiricist arguments against influential forms of scientific realism. In his Terry Lecture series he sought to view religion as well as science, and the philosophical enterprise, from an empiricist point of view, arguing that empiricists should see philosophy, not as metaphysical knowledge, but as an existential stance. The overall title for his lectures was The Empirical Stance. The titles of his four lectures were: Against Analytic Metaphysics; Empiricism as Will and Idea; Scientific Revolution/Conversion as a Philosophical Problem; and What is Science and What Is It To Be Secular? Professor van Fraassen joined Princeton University’s Department of Philosophy in 1982. His interests include philosophy of science (especially subjects related to probability theory and to the foundations of physics), philosophical logic, and empiricism. His the author of An Introduction to the Philosophy of Time and Space Formal Semantics and Logic The Scientific Image Laws and Symmetry (1989), and

THE EMPIRICAL STANCE Bas C. van Fraassen 304 pp. 5 1/2 x 8 1/4 Cloth ISBN 0-300-08874-4 What is empiricism and what could it be? Bas C. 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 second 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. “This work argues powerfully for a radical redirection of much contemporary thinking in epistemology and other important topics. It should force all of us to rethink the nature of analytic philosophy.”
