OK, the above seems to be talking about brains.
But at this point, you seem to start talking
about a different topic, viz. knowledge. Maybe
part of our inability to communicate very well is
an assumption that these are the same topic, or
even closely related? To me they are completely
different topics. (02)

range from this to... what? (04)
But in any case, in what sense is this a 'connection'? Connection between what? (05)

I guess I don't get the point here. Of course
some ideas last 46 years, who would expect
otherwise? I read journals that 'reach back' to
ideas that were discussed, and maybe even
accepted, in 2000 BC. (07)
>The topology of partial knowledge (08)
Topology of knowledge? Thats sounds interesting,
but why would you expect knowledge to have a
topology? What would continuity mean when talking
about knowledge? (09)

Sorry, Im completely puzzled. (011)
