The concept of the 'Homo Gestalt' was put forward in one sense, rather safely, in the genre of sci-fi in Sturgeon's 'More Than Human':
'...multiplicity is our first characteristic; unity our second. As your parts know they are parts of you, so must you know that we are parts of humanity'
The concept of conscious evolution to a stage where each part, or human, is an integral and interrelated part of the whole is an idea that is organically evolving within our mass mind. Now science is able to embrace this concept through delving into the psi-field of an integrated whole reality. As an evolving species, we are encouraged to work together as a synthesis, towards this synergy, or gestalt: where the whole is greater than its sum, and thus leads to emerging properties of the whole.
One area of research here is the 'global brain' phenomenon. Once the vanguard of peripheral thinkers (see Peter Russell's 'Earth Awakening: The Global Brain'), it is now fast becoming the ken of respected researchers: one recent example being Howard Bloom's 'The Global Brain', or Gregory Stock's 'Metaman'.
As parts of a larger system, humans can evolve into a conscious network and, using an apt analogy, may serve to become a planetary nervous system. Since univeral order is within a hierarchy, each stage evolving in complexity towards the next, we all exhibit characteristics of those systems above and below us, thus echoing the Hermetic adage As Above, So Below.
What concerns us now is functionality. And we can only function in accordance with our level of knowledge and capacity. We cannot be told what is, or what needs to be done: we can only be guided until that understanding becomes an inherant part of ourselves. Then we have an organic sense of how we should act to fit in with the dynamic whole.
Yet we can modify our base behaviours through observation and monitoring of oneself; to clear one's mind of trappings and junk in order to allow these new thoughts to penetrate. To contemplate and to kick-start the mind into thinking, delving, probing, questioning, and reaching out further beyond the confines of flesh and received-knowledge. We may think we learn, yet often we learn rote without the thinking. We should aim towards a conscious digestion of information. Like eating good food, be aware of it going in and its digestion. Use our capacities rather than leaving them to the junkyard of the sapians.
Open oneself up to synergy, empathy, and an awareness beyond the confines of the self. Think in terms of generations rather than immediate moments; into stages of species life rather than the slide into one's own old age. Think beyond oneself whilst including oneself.
Be conscious of ourselves as a part and simultaneously as a whole.
