When the soul departs from the body, does the consciousness remain the same or does it change because the brain no longer interacts with it? How do we know how much of our consciousness is that of the brain and that of the soul? If our consciousness is purely soul, then how do psychoactive drugs affect consciousness so profoundly? Why is it that people born with deficiencies or abnormalities of the brain are thusly mentally deficient? Is it simply that the brain is a physical manifestation of the soul, and what you are in physical life is what you remain?
Does the soul have an ego? Does the soul have a notion of where it begins and the universe ends? Does the soul have memories of its prior lives? If so, then wouldn't eternal life be not pleasurable since one could dwell on their past life? They could wish to return to a favorable past or fret over missed opportunities and regrets. Even if one has pleasant memories, wouldn't eternal cognizance become banal and boring since everything would eventually be experienced and known? If the soul forgets, then what is the relevence of eternal life from our perspective? Surely if our memories were washed from us, "we" as in our ego, would cease to be. After all, isn't the sense of self a culmination of past experience and interaction with the outside world?
Would it not be consistent with our current knowledge to assume that the soul has no memrory as such? After all, memories seem to be the domain of the brain. If someone receives specific types of trauma, mental or otherwise, then does it not sometimes result in loss of certain memories? If the consciousness is a resevoir of memory, why do we not remember before we lived our current lives? If, like I said, the soul has no memory, what is the point of assuming that eternal life would mean anything? What would "eternal" and furthermore "life" mean to an entity which moment to moment receives stimuli, but fails to retain? Wouldn't it simply be more akin to a vegetable than a man? Certainly no meaningful cognition could arise from a being in this state. Does such a fate make sense for the human creature?
If the soul changes in its fundamental sense of existence, then how is it relevent to our lot? Wouldn't it simply be as meaningless and incomprehensible as the thought of non-existence? If it remains the same, again I ask, what roll does the brain play in the functioning of consciousness?
