Because partial brain incapacity produces a state of oblivion that is identical to brain death. (Stuart Hameroff, Anil Seth). The conscious mind is an emergent phenomenon of neural data proccessing. When the neural network has been destroyed by any causality, the result is a gradually dimming mindscape as in Alzheimers and Dementia. I did not say "it is the same". I said that the effect is the same. (Seth, myself). Define soul. First, OT. Then Cell Theory. Long strands of self-duplicating polymers (RNA, DNA) encased in a self-organizing envelope and all the way back to basic chemical reactions and self-organization of biochemistry (Robert Hazen). I don't. The bible claims to know. Define soul. Like Carlos Castaneda? Allow me to ask: do other dimensions have access to our three? And if they do are they measurable? Have yourself anesthetized and you will understand. There is no evidence to the contrary. "I think, therefore I am" . Tegmark observes that "we already have all the tools necessary for conscious patterns. We have the pieces of the puzzle. And therein lies the problem. At that level any form of observation affects the data being observed and measured and the data itself becomes unreliable. But I have never seen a clairvoyant who's skill doesn't lie in the complexity of his/her "mirror neural" network, the network that generates "empathic responses". --- Yep, and also the more scientific metaphysical approach, and the psychological approach that define Angels and Demons as the symbolification of human character models. I always do.
