The examination of fictionality has long been a central concern in intellectual discourse, posing both complex and intriguing challenges. This chapter focuses specifically on fictional narratives, a category that differs from both the “fictional proposition”, as discussed in the philosophy of language, and “fiction” as a literary genre. While these concepts often overlap, they diverge in the scope of their application and implications. A fictional narrative is characterized by the interweaving of fictional propositions or statements alongside non-fictional elements. However, the primary aim of this chapter is to explore the mechanisms that make fictionality a defining attribute of such narratives.
