The real world doesn't add raindrops, or most other things we think

adding something like 10^25 atoms to another 10^25. But it _does_
add bosons in a BEC. Even when the constituents are
indistinguishable, nature can perform simple arithmetic with them.
I'd say *we* perform simple arithmetic to describe them - but only
when we correctly recognize what is countable and what isn't. So
the truth of Ax(x=/=x+1) is in Platonia.
But the truth that 1 raindrop + 1 rain drop gives 1 raindrops might too.
The difficultys is to get the relevant definition of raindrop in
Platonia, and comp shows how (in principle, given that we don't yet a
definition of water, nor of space, etc.).
If there is no persistent perception of raindrops in Platonia-seen-
from-inside, comp can't be correct.
