 In addition to challenging the traditional view that there is a qualitative metaphysical difference between memory and imagination, the simulation theory challenges the view that there is a qualitative epistemological difference between them. Philosophers have tended to be dismiss the possibility of episodic knowledge of future events, that is, of knowledge produced by imagining the future, as opposed to the sort of semantic knowledge produced by prediction (Kneale 1971; Swinburne 1966). The simulation theory, however, suggests that our episodic knowledge of future events may be on a par with our episodic knowledge of past events. This view is surprising, but it chimes with recent work on imagination as a source of knowledge (Balcerak Jackson forthcoming; Kind forthcoming).
