I like those kind of questions, some books made me find a personal way to mean at it: I would like to post just what was inherent.
I'm agree that so often there is a lot of talk and a whole connected World, but not so many real comunication, between persons.
The books I've read explain (you can take it as a "sci-fi") how the soul, to discover itself, needed to create a "mirror", so as like dualism is everywere, and it's were we loose ourself so often, but it was the only way, as "to be or not to be".
Anything "is" so made just for/from the soul, to take the opportunity to make the "experience", and to become from consciousness, awareness. And we are the humans, a container made for it, that's not so little to spend thinking on left or right, and any duality.
The books explains also how persons perceive the colors different, or as like also women and men perceive things on a different mood.
