I thought I had invented the thesis of "all thought processes are polarized"
There is no up, without down (to compare/contrast)
no in, without .. out
no black without white
hot and cold
good and bad
etc.
MY thought was, we develope grey areas so we can sanely function in a world that is aware of absolutes, but cannot operate within an absolute.
Jaynes's guess at 3000 y/a is way short though.
imo. I'll think about it.
