 The taxonomy in question, developed in detail by Squire (2009), divides the overarching category of memory into declarative and nondeclarative memory. Declarative memory, in turn, is divided into episodic memory, corresponding roughly to recollective memory, and semantic memory, corresponding roughly to propositional memory. A first pass at distinguishing episodic from semantic memory can be made by observing that the former is concerned with the events of one’s personal past in particular (e.g., I remember speaking at a conference in Budapest), while the later is concerned with the world in general (I remember that Budapest is the capital of Hungary). It is crucial to note, however, that semantic memory is also sometimes concerned with past events. One can have memories that concern events that one did not oneself experience (I remember that my colleague spoke at a workshop in Rome, though I did not hear him speak); when one does, one remembers semantically, not episodically. Similarly, one can have memories that concern events that one did experience but that are of the same kind as memories for events that one did not experience (I remember that I visited the CN Tower when I was a child, but only because my parents later related the story to me); when one does, one likewise remembers semantically, not episodically. Thus the first-pass distinction between episodic and semantic memory does not get us very far. Drawing a more adequate distinction—providing a criterion of episodicity—is a core problem for the theories of episodic remembering discussed below.
