Very interesting article. Short and full of fhings to think
   about. I think mathematical treatment of "degrees of freedom"
   within systems (dimensionality) is a very important issue to
   discuss and work through philosophically.

   At the same time - being that these are human systems, the
   systems themselves do not contain all of the information
   required, for there are many activities that are not within the
   sight of the system in question.

   [what happens behind closed doors, the uncounted (homeless),
   etc)

   Nonetheless, a very useful exercise for philosophers to
   investigate, especially in these days where mathematical
   complexity is a much simpler matter than it once was. I remember
   first learning about it in 1990; a friend of mine at college was
   studying AI, neural networks, chaos theory and complexity
   theories as they existed at the time. His biggest thrill was a
   decent "Game of Life" he had running that he wrote and added
   higher dimensions to, and my biggest glory was my copy of
   FRACTINT to make fractals on my 286 or whatever I had at the
   time.

   We've gone a long way, and have a long way to go, but there's a
   lot we can do with what we have at present.
