I suggest that there are two opposing ways of dealing with the world that are both vital but are fundamentally incompatible, and that therefore, even before humans came on the scene, required separate treatment, even neurological sequestration from one another. 

One tendency, important for being able to get things from the world for one's own purposes, involves isolation of one thing from the next, and isolation of the living being, perceived as subjective, from the world, perceived as objective.

The drive here is towards manipulation, and its ruling value is utility.

It began in my view by colonising the left hemisphere, and with the increasing capacity for distance from the world mediated by the expansion of the frontal lobes as one ascends the evolutionary tree, resulted in a physical expansion of the area designed to facilitate manipulation of the environment, symbolically and physically, in the higher monkeys and apes. Eventually that expansion became the natural seat of referential language in humans.

The other tendency was centripetal, rather than centrifugal: towards the sense of the connectedness of things, before reflection isolates them, and therefore towards engagement with the world, towards a relationship of ‘betweenness’ with whatever lies outside the self.

With the growth of the frontal lobes, this tendency was enhanced by the possibility of empathy, the seat of which is the right frontal expansion in social primates, including humans.
