In this paper I defend the claim that the act of writing a work of fiction consists in the performance of a sui generis speech act, and propose a dynamic treatment for acts of fiction-making. Recently, speech act theories of fiction have become targets of the uniformity argument. According to it, in order to account for the myriad of speech acts present in works of fiction, speech act theories of fiction need to propose a similar amount of fiction-related illocutionary forces. (...) When uttered in the same context, these illocutionary forces give rise to the same relations raised by their non-fictional counterparts. While not a knock-down argument, this warrants an explanation. In order to defend speech act theories of fiction, I argue that the claim that speech act theories of fiction need more than one fiction-related sui generis illocutionary force is misguided and rests on an erroneous account of the content of an act of fiction-making. I take that the content of an act of fiction-making is more akin to a speech report than to a regular assertion. Following, I propose a dynamic treatment to the speech act of fiction-making. Concluding, I explore some related topics in order to distinguish my proposal from pretenseapproaches to fictional discourse. (shrink)
