I may get pooh poohed here, but to me, this discussion is one of a spiritual nature. My belief is that God created all things spiritually first, before he created them physically. And, God is what gives all life it's sentience. Understanding the brain is only part f the equation. The soul of man (and woman) is both the physical body (including the brain) and the spirit. Until we can fully grasp the spiritual, we will never be able to make the "leap" between paper and conscience. Anyone else feel this way?
