Dear all, Please join us for the CamPoS (Cambridge Philosophy of Science) seminar
Wednesday 12th 1-2:30pm in HPS Seminar Room 2. Theo Kuipers (Groningen) will give a talk entitled "Nomic truth approximation by revising models and postulates in the light of increasing evidence". The abstract is below. Best wishes, Christopher Abstract: The qualitative theory of nomic truth approximation, presented by Kuipers (2000), in which 'the truth' concerns the distinction between nomic, e.g. physical, possibilities and impossibilities, rests on a very restrictive assumption. This paper drops this assumption by fully recognizing two different functions of theories: excluding impossibilities and representing possibilities. Accordingly, theories are conceived of as tuples of postulates and models, where the postulates claim to exclude nomic impossibilities and the (not-excluded) models claim to represent nomic possibilities. Revising theories aiming at truth approximation becomes then a matter of adding or revising models and/or postulates in the light of increasing evidence. Here, truth approximation is defined as a matter of increasing truth content and decreasing falsity content.
