Theoretical accounts of fiction, once confined to the field of aesthetics, are now widely considered as useful frameworks for philosophical investigation more generally. Fictionalist tendencies in various disciplinary fields regard possible worlds, scientific theories and models, numbers, propositional attitudes, mental entities, and the self as if they were fictional objects. In the context of fictionalist-oriented views, imagination has been given a special attention. The workshop will push forward the discussion of the advantages and limits of deploying the aesthetic notion of fiction outside of its original domain, with an emphasis on imagination’s role and nature.
