  In this paper we discuss and analyse the idea of trying to see
(non-relativistic) quantum mechanics as a ``space-time statistical mechanics'',
by using the classical statistical mechanical method on objective microscopic
space-time configurations. It is argued that this could perhaps be accomplished
by giving up the assumption that the objective ``state'' of a system is
independent of a future measurement performed on the system. This idea is then
applied in an example of quantum state estimation on a qubit system.
