@Fil Albuquerque,
Fil, this is an example of what I referred to as your improved use of English--good writing--but you must have meant "cosmogonies".
Now let me suggest that the dualistic notion of "self" (versus others) has utility because societies could not operate without them, (
Ego is "universal" despite its variations cross culturally: a non-dualistic perspective has spiritual accuracy but it is useless regarding the "functional requirements" of social systems. Society is a "unity", in the sense of being a collection of individuals whose interactions enjoy some co-ordination regarding norms and themes, but, according to "methodological individualists" in Sociology, only the individual has ontological reality as opposed to the purely abstract quality of "society." Looking at the pluralism characterizing our (otherwise "thinged") society we can see that neither position is completely adequate.
With respect to your question to Fresco regarding the "self of society," I would suggest that society's "group culture"--and keep in mind the cultural pluralism of most complex societies--as functioning
with respect to norms (e.g.,values, laws,and understandings) that are shared to a degree, but rarely completely. With that reality in mind, we might refer to our society has having a "collective culture". Our mythical but functional "social selves" * best refer to the fact that each of us is more or less successfully socialized or enculturated into the dominant normative system our society. With that in mind can we say that we are both inside society and society is (more or less) inside us?
*you suggested "social self" as a synomyn for "group culture".
