As someone who memorizes terms and concepts related to metaphysics… I can only conclude that I am not an actor! If ontological understanding is every coming, I haven’t seen the script by which to act, let alone understand… 
Which leads me to some fave quotes from A Question of Memory (Berglas).
One is that memory is not a unitary mechanism, but a behavior.
The other is that each must interpret the tradition of on one’s own, emphasis on interpretation being itself a behavior grounded in doing.
