SWM & S.Earl Martin: I may end up apologizing to you 'out of my compassion for your innocence'. Your doing something so automatically, you don't see yourselves doing it. Like the 'blind spot' when driving a car, only this is a 'blind-spot of the eye', also known as "scotoma". (mental-scotoma? )
SWM, you mention my 3 anecdotes separately rather than by the common denominator; thus; the earth was flat, the gun was empty, the snake is a rope. WHOA; "the snake is a rope" you wrote.
Even if you had written it as "the rope is a snake" you still have it wrong. The word 'is' implies identical; equivalent. The rope was the empirical fact, the snake a image from memory, by what 'legerdemain' or 'alchemy' can you "equalize" a empirical fact and a mental image?
Let me tell you the common denominator of the 3 anecdotes: the flatness of the earth was a "belief", the emptyness of the gun was a "belief"; that the rope was perceiced as a snake was a "belief-perception". Remember this phrase, BELIEF-PERCEPTION. ( I do believe I coined it, I have not seen it anywhere; you see it here first, I 'm sure.)
