Sorry i'm late in responding to your question, Ted.
i'm a little slow remembering which threads to go back to and all the way
through---still learning the new ropes.
Epistemological verifiability was a way to play with my UNC-Chapel Hill
bud, Brian W. ---a little academic bantering between a Davidson Wildcat and
a CH--Tarheel. When he refers to the word 'proof', it causes those of trained in philosophy during the archaic period to hustle to the field of epistemology
(how do we KNOW something---how do we PROVE it---how do we VERIFY
the reliability of our criteria composing our proof). I could go on but i know better.
but thanks for asking, old friend. and thanks for the word 'elucidate'---one of my absolute favorites.
best,
barry
