Here is the bottom line: just as the eyes are the portals for vision, and just as the ears are the portals for hearing, proprioception, as a global term for the combination of all the internal senses, is the portal for consciousness. Human beings have two minds. One mind creates space, the other mind creates time. Unfortunately, these two cognitive processing networks don't know they have a twin-that is the great paradox of our existence as human beings, the irony of it all. We have two minds-not just two sets of behaviors, not just left-brain/right-brain, or top-brain/bottom-brain, and not just two theories, although I base my ideas on an evolving discipline called dual-process theory. I contend that we have a hardwired, no-getting-around-it, dual-cognition. Our dual minds did not come about because we have two brain hemispheres-I don't mean right-brain versus left-brain when I speak about our cognitive duality. I am referring to something new in the debate about consciousness. -The reason evolution created brains and nervous systems is so that animals could navigate from one location to another. Trees don't have nervous systems, brains, senses, and muscles, because they do not navigate-they are rooted to the earth.
