Norbert Wiener who coined the term
cybernetics basically distinguishes between two different notions of time, Newtonian time
and Bergsonian time. Newtonian time is an ideally simple science. As Wiener puts it, in
any such theory the future after a fashion repeats the past and the book of astronomy
reads the same backwards as forwards. When all this was reduced by Newton to a formal set
of postulates and a closed mechanics, the fundamental laws of this mechanics were
unaltered by the transformation of the time-variable into its negative.
In certain cases dissipative behavior can be derived directly from a conservative systems
dynamics without introducing any sort of approximation. Therefore, time-directed phenomena
are not generated artificially by statistical arguments, but are based on an exact systems
analysis.
