 Regarding the second aspect of mnemicity, the simulation theory implies that the difference between memory and imagination is much less dramatic than the traditional view takes it to be. Hopkins (forthcoming) has described memory as imagination controlled by the past. If the simulation theory is right, memory is indeed imagination, but it need not be controlled by the past. One may merely imagine a past event by imagining a counterfactual past event. But if one imagines an actual past event, and if one’s imagination is reliable, then one is simply remembering it. There is, if the simulation theory is right, no difference in kind between cases in which one reliably imagines an actual past event at least in part on the basis of one’s experience of the event and cases in which one reliably imagines an actual past event on another basis; in cases of both sorts, as long as one’s representation of the event is accurate, one has a genuine memory of the event.
