Oooo... tough call.... civilization... eeek... civil... given
   the behaviors of individuals that live within geographical
   boundaries under a common set of laws with enforcers of that law
   in various forms, along with other sets of laws with enforcers
   that are unwritten (I think mean-girls as one example)...
   ... it's hard for me to see civilization as a reality either.
   I can, at present only go with cultures and subcultures. I'm
   'atheist' (metaphorically speaking) to "society" and
   "civilization".

   Odd too, because I had once considered becoming a sociologist.
