Complex systems theory is a post-human-centric viewpoint, meaning that
it focuses on the nature of the system. The properties of the system
are more important than whether it is human or not.
The core property (the moment of complexity):
"...what a system does by virtue of its relationship to its environment"
http://en.wikipedia.org/wiki/Richard_Lewontin, though not a complexity
theorist himself, per se, gave a thorough picture of how this works
with living things. He also explains why this prevents us from
programming genes like a computer in the same book.
On each scale, from micro, to macro, "...what a system does by virtue
of its relationship to its environment" results in multi-scalar
emergent behavior. What you see as a "human" is now the result of
millions of these evolutionary relationships (what I referred to
earlier as "connections"). They are emergent connections.
It is possible to *model* emergence with computers. People have been
doing this for years
It is NOT possible to PROGRAM emergence.
This means that it is possible to program complicated behavior (like
the behavior of machines of any type), but not complex behavior (like
the behavior of emergent systems like ants, stockmarkets, and
Emergence is the result of simple rules and functions on many scales
*interacting* and leading to complex behavior (not complicated
I hope this helps.
