Avril, I've had a long-term interest in Bohm's notions, and would appreciate
any pointers you may have to the information you cite. This could be off-line.
(01)
Thanks much,
Leo

Richard and all,
(04)
just a short note. The hierarchy of levels is central to e.g. David
Bohm's ontology and a good intro to that can be found e.g. from Paavo
Pylkkänen's Mind, Matter and the Implicate Order.
(05)
I've been developing a collection theory for a while that formalizes
the level hierarchy of relationally structural properties (the term is
from Armstrong), like colours. The central tool in that collection
theory is the membership relation epsilon, inherited from set theory.
For instance, a level n property P_n is composed of level n-1
constituents, where the constituents are members of P_n. The
constituents of a property are lower-level properties and relations.
P_n = the constituent properties of P_n + the relations between the
properties. Emergence is a tag for complexity that is not understood
or explained.
(06)
If anyone is aware of citations of systems alike, please let me know, thanx!
