now youre standing somewhere and im
     standing somewhere in semantic space    and theyre not the
 same place    because i find it hard to imagine us all or any of us
     standing in precisely the same place even in semantic space
      now supposing from where im standing "blue" looks pretty
     close to abstract    and from where youre standing it looks
    pretty close to concrete     i can imagine your position and you
   can imagine mine      how can we each get to imagine the others
     position    how come i can imagine your position as well
     as mine?     how do you get to imagine my position as well as
    yours?
