II. Memory
Then how to define memory?
Quoted from Epistemology of Memory, memory is an approximation of some facts. In other words, memory generally alters significantly what enters it. When we recall some episodes of the past, those recollecting are not the retrieving, but rather the generating of representations of the past. It actually generates new beliefs about the past.
There are two common categories of memory, which are Semantic memory that indicates proposition of memory, and Episodic memory that refers to actual events of memory. Epistemic theory, therefore, mainly focuses on these two kinds of memory and illustrates an interesting concept, that is whether practical knowledge can be fully understood in terms of various propositions. In simpler words, the goal is to explore whether knowledge-how is reducible to knowledge-that, and how to use various knowledge-that to build knowledge-how.
