S.Earl Martin, I like your reply #10, I find it informative.I would like to address everything you 'bring up', that might be lengthty(may require two replies).
You don't agree that insight has to come from within, that it can come from something someone else says or does, or just from observation. What you wrote seems innocuos but I will make "a big deal" about it, because it perpetuates a false belief of the magnitude of flat/round earth. Do you know the ABC model of cognitive psychology? Your comments don't indicate you believe nor practice it,( I 'slip up' all too often also). Epicteus said;"It's not the facts that disturb us but our thoughts about them." Albert Ellis 'elaborated' that into Cognitive Psychology, etc.
Your example of insight coming from without;Issac Newton recognizing gravity. On that auspicious occassion, he saw a apple fall, etc. That 'Event A' did not do anything to his brain/mind, but it was the occassion for Issac to do something with his brain/mind that resulted in his recognizing gravity. In persuing "Event A" (genericly). " A tree falls in the forest, is there sound?" Vibrations are set in motion, which travel in waves, if there's no ears or other recording devices, there is no 'sound', the waves pass. Now lets consider a jet plane causing vibrating waves. The plane is gone before the vibrations reach your ears, heard as 'sound' (no ears, no sound). Apples fell, but until Issac showed up, gravity was not recognized as a principle.
Did you ever consider a mirror as a 'recording device'? (of photons of light). The object being reflected does NOT DO anything to the mirror, the mirror does the 'reflecting'(brain/mind wise.)
'Insights' come in the form of or manifest as 'thought'. 'Thought' comes from brain/mind, not from 'Events, if events did 'cause' insights, with such myrid of events, why so few insights?
I'm curious about your D-Text, where can I see a copy? You write my sentence composition is unclear. That brings me to voodoos fine reply. I do not have any academic credentials, no college, not even a high school diploma. I'm out of my 'league' education wise here. On November 1st I will be 83 . It's not likely I will study sentence composition, I'll make due with what i already have, plus access to original thoughts.
Epictetus 'insight' has not yet 'filtered into, nor imprinted into mass consciousness.
Several times I thought of unsubscribing from this site because I was not conveying what I intended, but after I post, I read it like any other reader and 'get mini-insights' about what to write next; I obseved the 'evolution' of my thinking right here, this is as good as journaling, for me. Thank you all for your patience.
