  According to Reid, episodic memory is not a current apprehension of a past event, nor is it a current apprehension of a past experience. These theoretical options were ruled out by Reid’s criticism of Locke and Hume. Rather, according to Reid, memory is an act that preserves a past apprehension. Reid characterizes memory as exhibiting what we now call the Previous Awareness Condition. He holds that reports of episodic memory are true only if the person reporting satisfies the condition, and that experiences that otherwise appear to be episodic memories, but which fail the condition, are not episodic memories (Essays, 264).
