Hi Avril, Comments below, -Rich Rich Cooper EnglishLogicKernel.com Rich AT EnglishLogicKernel DOT com 9 4 9 \ 5 2 5 - 5 7 1 2
-----Original Message----- Richard and all, 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.
Do you have a preferred URL reference? I am not familiar with that work.
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.
The word "emergence" has been treated quite casually in the literature, ranging from inert matter to the behavior of crowds. So it would be nice, as you point out, to formalize how each layer of that emergence is brought to effect on the layer below. But history shows that generalizing from one level to the next is fraught with inaccuracies.
If anyone is aware of citations of systems alike, please let me know, thanx! -Avril
Same here; I think the whole Self Interested community will be interested, -Rich
