It is not, I believe, too much to say that all the vital problems
of philosophy depend for their solution on the solution of the problem
of what Space and Time are and more particularly how they are related
to each other.
The problem of time has always baffled the human mind.
The modern advances in thermodynamics, relativity, cosmology
and information theory, instead of clarifying our insight into this basic
notion (time), seem so far only to have added to the general confusion.
There will have to be some new development that is quite
unexpected, that we cannot even make a guess about.
