This is a vital piece of evidence (perhaps even proof) that there is an intrinsic separation between mind and body.

It concerns Freud's (and Jung's) analysis of the mind into 3 core parts : Ego, Id, and Superego.

Briefly : Id is the instincts, Ego the "I", and Superego the conscience.

These vital aspects of mind simply cannot be disputed. (Though many of you will no doubt try). And yet they have absolutely NO direct connection to the brain.

Even more vital, is the distinction between consciousness, subconsciousness and unconsciousness. Once more, the connection between these aspects of mind have no direct correlation to the brain.

Now some aspects may have indirect connections to the brain.
But nowhere in the brain is there a singular object that can be always mapped as the seat of the "I".

"I"-ness moves all over the brain, body and external world. When a part of the brain is damaged; the faculty that is associated with it can move to another part of the brain. Its similar to the way in which if your correct hand is amputated, you just learn to use your other hand for the tasks required.
