  EVERYBODY agrees, that's the way it is, with 
  *Neuro-science, and Walter Cronkite*. 

  What the higher forms of intelligence on Earth 
  are trying to establish with the dolts in 
  Bionet, and AI though, is that that's 
  NOT the way it is EVERYWHERE.

  It's only that way in *mircro-biology* classrooms.
  It's NOT that way in *Chemistry*.
  It's NOT that way in *Biology*.
  It's NOT that way in *Math*.
  It's NOT that way in *Computers*.
  It's only that way in 
  *Einstein's moldy brain*, and *QM-syncopated* Psychologists.
