The zeitgeist determines the models that are explored, accepted, or rejected.
Knowledge builds upon itself in the minds of the observers.  Different
individuals reorganize the information and communicate the information to
all.  If the new organization is accepted it grows.  If not it dies and waits
for rediscover.  We are acting like a collective mind with different
sensors (observers).  Birds fly together.  There wing beats are coordinated.
Any individual can change the path of the group.  The group effects
the path of the individual.  Ron Blue
