Düsseldorf): Impossibility Results for Rational Belief DESCRIPTION:Im Rahmen des Forschungsseminars laden wir recht herzlich ein zum Vortrag:Prof. Gerhard Schurz (Univ. Düsseldorf)\r\n\r\nImpossibility Results for Rational Belief \r\n\r\nAbstract\r\n\r\nThere are two ways of representing rational belief: qualitatively as yes-or-no belief\, and quantitative-ly as degrees of belief. Standard rationality conditions are: (i) consistency and logical closure\, for qualitative belief\, (ii) satisfaction of the probability axioms\, for quantitative belief\, and (iii) a relationship between qualitative and quantitative beliefs in accordance with the Lockean thesis. \r\n\r\nIn this talk it is shown that these conditions are inconsistent with each of three further rationality conditions: fallibilism\, open-mindedness\, and invariance under independent conceptual expan-sions. Restrictions of the Lockean thesis that have been suggested in the literature cannot remove the inconsistency. In the outlook I discuss alternative ways of dealing with this problem\, such as restricting conjunctive closure. \r\n\r\n LOCATION:24.53.01 Raum 81 ORGANIZER;CN="Institut für Theoretische Philosophie": END:VEVENT END:VCALENDAR
