In turn, incidentally, I've written a guest post for Oronte Churm. It's here, and it's about a short story I use in my engineering ethics class by the brilliant Chinese author Gao Xingjian, called "The Accident."
In it, I touch on certainty, and although I don't know that this was intentionally placed there, I notice this quote at the top of Churm's page:
The quest for certainty blocks the search for meaning.
--Erich Fromm
I think dealing with that idea is part of the same conversation, in some way, that Wyatt Galusky brought up last week on mystery and "the remainder" -- that space left over once we put objects in the world (beyond humans) into concepts (human-made), the space between what we know and what we don't. I won't be so bold (or foolish) as to offer a theory that holds the prior mystery post to the currently linked certainty one, but I'll leave the thought out there. For cogitation.
