the kind of technology back then I think was less based on categorization and separation or distance, I mean there was a philosophical difference between the logic of categorize, transmit, replicate, and multiply that is in operation right now or our current logos, and I think the there technology was more based on direct unification with some kind of natural energy that pervades our mode of existence.. philosophically though I think instead of based on bifurcation or dichotomy, instead of going outward, they went inward and understood that true reality is not quite what our limited senses insist on form and substance and separation, if a change in understanding, -or vision- was in effect for a civilization, their entire reality would be fundamentally different with a relationship to the Earth that we did not think possible. IMO.
