Truth in fiction, impossible worlds, and belief revision
MetadataShow full item record
We present a theory of truth in fiction that improves on Lewis's  ‘Analysis 2’ in two ways. First, we expand Lewis's possible worlds apparatus by adding non-normal or impossible worlds. Second, we model truth in fiction as (make-believed) belief revision via ideas from dynamic epistemic logic. We explain the major objections raised against Lewis's original view and show that our theory overcomes them.
