Human's are "the Earth thinking"

“In a manner of speaking, the birds and the insects are indeed living portions of the earth flying, even as, again in a manner of speaking, bears and wolves and cows and cats represent the earth turning itself into creatures that live upon its own surface.  And in a manner of speaking, again, man becomes the earth thinking, and thinking his own thoughts, man in his way specializes in the conscious work of the world – a work that is dependent upon the indispensable “unconscious” work of the rest of nature, a nature that sustains him.  And when he thinks, man thinks for the microbes, for the atoms and the molecules, for the smallest particles within his being, for the insects and for the rocks, for the creatures of the sky and the air and the oceans.

“Man thinks as naturally as the birds fly.  He looks at physical reality for the rest of physical reality: He is earth coming alive to view itself through conscious eyes – but that consciousness is graced to be because it is so intimately a part of earth’s framework.”

(Dreams, “Evolution” and Value Fulfillment, Session 899)
