Re: the "(M,R)-System" model, Modeling relations, and semantics

Hi Judith and John,
Classic physics deal with end points, trajectories,
and movements hence deal with change. But this change
is reversible. The film can be rewinded. I wonder
how irresibility (arrow of time, rate of change etc.)
is explained in your model which time is not dealt
with directly. According to Jantsch the study of
universe must include at least three levels of inquiry
of physics which refers to what Pattee means matter
aspect which is logical the language of which is
mathematics. the symobol aspect is formal and hence
is eternal and timeless the language of which is
archetyes.
