Keith your words do make more sense (more easily digestable), on re-reading them once the point is understood.
Your "perceivable" is only from an anthropocentric point of view, since it is only 'our' mind that we recognise/accept perception from/in.
The perceptions assembled by any other 'else' is out of our realm, thus irrelevant to our own actual perceptions.
Parts of the concept reminds me of religious archaeology: 'god made the dinosaur bones and coal [and radioactive decay etc.] so they seem old, though they were all created rather recently'.
I often wondered how it all "came to be" from childhood, after realising that the people who claimed to know, gave explanations that made no sense at all, without blind faith in nonsense.
"(“I fired my first god as soon as I found out.”)", so did I !
"Switching frames": I wanted to head that way, and the more I tried, the more the old frame tangled me in knots of 'potential loss', and piles of stuff I 'couldn't do without', without losing family, friends, ego, and the ME game.
The land YOU walk on may be flat, but map makers have named and agreed that at least parts of the land are not; it could be true.
A flat Earth puzzle I read somewhere is a flat disc Earth, where as you get further and further from the centre, the relative size of everything on the disc decreases, including your measuring instruments, so you can never reach the outer limit from the 'on disc' frame of reference; an apparently 'infinite' expanse of flatness according to any on disc measurements.
Here is a conundrum: nothing is curved, all is merely straight lines between points; nothing is straight, all is curved, as the smallest things' surface curvatures make straight lines impossible.
Word is nothing and useless unless another perceives it and both agree on a meaning, so entire new languages can newly exist (from nothing) if more than one can agree on a structure, and speak and understand it. [eg. Lord of the Rings; Star Trek.] Some old languages are being re-born by people using it again, and agreeing on current meanings, since the exact original meanings have expired with the old folk who formerly used it.
Sorry if I seemed flippant about your decades of thought put into the equation, but I enjoyed it. I've done a lot of mind bashing navel gazing, philosophising, and like that sort of thing, [I need a girlfriend to help waste my time].
Thanks for the welcome to the clubless.
Funny thing is, the way I think, other people want to use a club on me !
If you are well off enough to seriously think about 'really' changing frames, see 'The Magnificent Deception' video. It tells of the false perceptions created to control populations and profit from them, making them not Free Men.
