Retroactive Continuity and Fictional Facts

This paper deals with the phenomenon of retroactive continuity, or retcon for short, in which the truth-value of a proposition in an established fictional work is changed later. The primary aim of this paper is to provide the most compelling explanation for retroactive continuity. I first defend the metaphysical view about fiction, according to which when retconning occurs, a fictional work changes its property of containing a proposition while preserving its identity. I then argue that this view is theoretically preferable to all other competing approaches.
