Emergent Systems / Theories in General > s.a. realism.
* History: The
earliest representatives of emergent theories were Plato, Aristotle
(anti-atomistic, but not a process philosophy); In the 20th century,
G H Mead, H Bergson, A N Whitehead, J Margolis, P Teilhard de Chardin.
* Idea, I: Emergent
properties of complex physical systems are those that cannot be understood
solely in terms of the laws governing their microscopic constituents,
i.e., taking a reductionist approach.
* Idea, II: In determining
the macroscopic or classical properties of a system, the process by
which an effective description appears from a more fundamental system is
more fundamental than the substance of the fundamental system itself.
