The physical space is not the geometrical space and this is not the
algebric space.
The philosphical space transcend this.A philosophical space thinking
can think that
the space is the other;s field and this is in his relation.The spacial
thinking is from the agent's
from the resolver's point of view and this is the system for his
completion and this is for his egalization
with other.This is from his default,from his morphologicals defaults'
point of view.
The real space is not with our objective space identical relations.
This is the other system.
Go to the group"the resolvatism-a philosophy"for a resolvatist space
philosphy.!
The science give the necesairies conditions for the possibiles actions
and the knowledge
give the structures of this conditions from the resolver' objective
point of view.
The space is absolute and the time is not absolute,it is a consequence
of infinite(?) sequence
finite events.
