We can know the past by accurately remembering events we experienced. Yet whether a memory accurately represents a past event depends on whether the memory successfully refers to the event. How do memories refer to their objects? One answer to this question falls neatly out of traditional causal theories of memory: reference is secured by a causal link, sustained through a memory trace. However, recent advances in memory science suggest that remembering is an inherently constructive rather than preservative process. Motivated by these empirical findings, the new philosophical paradigm treats remembering as a species of constructive imagining. This paper raises a novel challenge for the most influential representative of the constructivist paradigm: simulation theory. The challenge is to explain how remembering, so understood, could secure the right referential link to past events. It argues that simulation is unable to perform the reference-fixing role previously assigned to memory traces. In dropping the causal condition on remembering, simulationism has no viable route to explaining memory-based reference to, and therefore knowledge of, the past.

Remembering one’s past generically is a rather ordinary feature of mental life. I can recall my daily commute to campus, from my past perspective on my bicycle, without thereby picking out one specific occasion on which I made that commute. Memories of this form have received little theoretical attention in the philosophical literature, in part because it is difficult to see how to divorce _episodic_ modes of representation from representational _uniqueness_. The current paper makes progress on the question of how an episodic memory could have for its intentional object something that is not a unique episode. It proposes an analysis of generic episodic memories on which the remembering subject represents an event _type_. Genericity over episodes is best explained in terms of the subject’s knowledge of what it was like to experience events of that type.
