Maybe it is egotistical to attribute any intelligence to ourselves as human beings.  Maybe we just tap into some universal intelligence and the brain and the heart are the machinery we use to do this.  Maybe some people are more able to tap into it than others but since it can be taken away with health problems, accidents and the like perhaps we are attributing to the human body that which is the result of the spirit.  It's just a thought I had as I listened to this interview, which I found extremely interesting and thought provoking.  It was a great discussion on both sides.
