I like this comment. It seems to me that we do forget some of our learnt wisdom and to be reminded of things we 'know' that we may have forgotten is a very human and therefore valuable thing. Maybe the purpose of the whole oral tradition - but I'm out of my depth here. The lyrics of a song (from the seventies?) summarize this for me - once you exclude the sentimental aspect: "I have a friend who's going blind, but he sees much better than I".
We do forget! Recently there have been too many times where I “realized” something important or profound, only to go back and see it in my writing from years ago.
So, like the sibling comment about prayers, I’m trying to build a system that collapses those insights into a small enough space that I can review them regularly. Kind of like regression tests for mind function.
