I'm just wondering if this is a part of Ne, but when you think of concepts, does it have a visual imprint in your mind?
For example, let's consider a somewhat complex thought:
capitalism versus socialism
When I think of something like that, I think of two armies, where one is represented by the business class, the other, represented by the state (government), and they battle on Middle Earth or something.
Not necessarily that I want to put LOTR universe in the mix, but it just gives me a somewhat surreal picture of the two ruling entities that clash.
Anyway, I think that for most of the things that get stuck in my long term memory, they need to have some sort of a visual (if not other sensory) imprint in me, otherwise, sheer textual information can easily be forgotten.
1 mile = 1.6 kilometers -------> forgettable
1 mile = roughly from my house (point A) to a certain mall (Point B) -------> easily remembered.
