The logic seminar will meet as usual this Thursday from 4 to 5.30pm in the Graduate Common Room. Catrin Campbell-Moore will be talking on "A revision theory of probability". University members welcome. Abstract below.
Michael Potter Revision theory of probability The revision theory of truth is an influential theory that is used to study sentences which talk about their own truth, like the liar sentence. I will consider how one might develop a revision theory of probability allowing one to study sentences which say something about their own probability. This will result in features such as that the probability of the liar is a half. The notion of probability that is being developed in this revision sequence is one of semantic probability, which measures the degree of truth of a sentence. When real numbers are in play instead of just the truth values true and false, one needs to reconsider how to 'sum up' facts and generalise the limit stages of the revision theory. _____________________________________________________ To unsubscribe from the CamPhilEvents mailing list, or change your membership options, please visit the list information page: http://bit.ly/CamPhilEvents List archive: http://bit.ly/CamPhilEventsArchive Please note that CamPhilEvents doesn't accept email attachments.
