Card 2.2.3 · Root II — Epistemology
Memory
Is remembering a kind of perceiving, or a kind of imagining?
Memory is the capacity to retain and retrieve what was previously experienced or learned — and the question is what kind of source of knowledge that makes it.
Where it sits
Under 2.2 Sources of knowledge. Borders 1.3.2 Personal identity, 2.2.4 Testimony, 6.14 Philosophy of psychology.
The rival answers
| Position | Memory is | The difficulty |
|---|---|---|
| Causal theory | A state causally connected to the original experience | Allows deviant chains — a relearned fact can feel remembered |
| Simulationism | Constructive imagining, aimed at the past | Then what distinguishes memory from imagination? |
| Direct realism | A relation to the past event itself | Hard to state without backward causation |
| Preservationism | Storage and retrieval of retained content | The empirical work suggests reconstruction, not storage |
| Epistemic generativism | Memory can produce justification it never originally had | Conflicts with the intuition that memory only preserves |
