Dear all, This is a reminder that, tomorrow, Dr. Luke Fenton-Glynn (UCL) will give a talk entitled "Unsharp Best System Chances". An abstract is included below.
The meeting will be held at 5:15pm on Tuesday, 11 February, in the *Boys Smith Room *(found in the Fisher Building), St. John's College. For more information, including details about our fees, and our 2013-2014 programme, please visit our website at http://www.phil.cam.ac.uk/seminars-phil/seminars-msc. We look forward to seeing many of you there. Best, Kyle Mitchell and Shyane Siriwardena ABSTRACT: Much recent philosophical attention has been devoted to variants on the Best System Analysis of laws and chance. In particular, philosophers have been interested in the prospects of such Best System Analyses (BSAs) for yielding *high-level* laws and chances. Nevertheless, a foundational worry about BSAs lurks: there do not appear to be uniquely appropriate measures of the degree to which a system exhibits theoretical virtues, such as simplicity and strength. Nor does there appear to be a uniquely correct exchange rate at which the theoretical virtues of simplicity, strength, and likelihood (or *fit*) trade off against one another in the determination of a best system. Moreover, it may be that there is no *robustly* best system: no system that comes out best under *any* reasonable measures of the theoretical virtues and exchange rate between them. This worry has been noted by several philosophers, with some arguing that there is indeed plausibly a set of tied-for-best systems for our world (specifically, a set of very good systems, but no robustly *best* system). Some have even argued that this entails that there are no Best System laws or chances in our world. I argue that, while it *is* plausible that there is a set of tied-for-best systems for our world, it doesn't follow from this that there are no Best System chances. (As I will argue, the situation with regard to laws is more complex.) Rather, it follows that (some of) the Best System chances for our world are *unsharp*. -- Kyle Mitchell and Shyane Siriwardena Secretaries of the Moral Sciences Club Faculty of Philosophy University of Cambridge [email protected] http://www.phil.cam.ac.uk/seminars-phil/seminars-msc
