And isn't it interesting how the continuity of our state of being and enduring sense of self seem to be entirely contingent upon the normative function of the precise replacement of these cells? To suggest that the mind is something that can endure continuity apart from the mind is faced with the problems caused on the mind by the impact of discontinuity of the material cells ability to seamlessly replace themselves. If the mind is something separate, then why is it that when physical cells fail to replace themselves, or replace themselves with bad cells, the result is degenerative brain diseases or other debilitative trauma? Such diseases have drastic negative impact on the mind's cognitive functions and the senses of consciousness which correspond to them. If the whole brain is damaged, what reason is there to think that the mind will be magically restored and maintain separate continuity apart from its physical vessel? Dualism is constructed of layer upon layer of impossibilities and irreconcilable problems such as these. Until a single substance explanation can be completely ruled out, I see no need in entertaining the absurdities of adding nonphysical "stuff", ectoplasm, pixie dust or any other magical substance to the equation.
