Fictions are a cornerstone of human cultures: they are created, shared, discussed, modified, and valued. Yet, philosophical accounts which privilege the ‘classical knower’ struggle to explain how fictions can affect us so deeply. Further, the fact that fictions seem to impact broader society and whole populations is largely overlooked, despite being observed in other disciplines. In this talk, I will draw on theories from philosophy of language, philosophy of mind, aesthetics, and epistemology to argue that fictions offer us epistemic resources of a unique kind, and that these resources lead to knowledge practices which can eventuate in harm."
