"Such as the border around country which is just a line on a
map. It cannot be interacted with in any real way. Therefore, a
border around a country cannot be acted upon to move except by
analytical agreement of those aware of the border. For those not
aware of the border, it does not exist (unreal) in any form.
Things that aren't real can't move."
Seedy, of course it can be interacted with. It's a line on a
map. You can erase it. You can burn the paper. You can erase the
computer file.
If it's a concept in the brain, you can forget it through
physical means, or at least reduce its importance to smaller and
smaller amounts.
It's all quite physical.
The line on the piece of paper exists.
The shared mapping of that line on a piece of paper in the minds
of a lot of people is real in the sense of the brain wave
patterns that can be measured.
The correspondence of one to the other through shared agreement
is what makes it real in the mental maps. Granted, the ancient
brain maps we keep using are basically "wrong-ish" -
localization isn't as easy as the visual systems are, where
there *is* an actual matrix where a shrunken down view of
'what's around us' is projected in a sense in the back of the
head.
But there's still correspondence.
We can't see the wires, but they're there. But the physical
transactions of belief require the participation of the humans.
