Charles Russell wrote several times in The Watchtower that the "convolutions" of the brain will be reproduced in the resurrected body, thus giving the re-created being both the memories and the ability to recognize themself as the individual who had lived before.
Do you think that Charles Russell, who was not unintelligent, realized, at least to himself, that the individual who once lived could have no expectation to experience what the re-created being would experience in the future?
Did Russell really think about what he was saying? or did he not really care if what he said held up to examination?
Just because some creature in the future has the same "convolutions" as a being in the past did does not mean that the personal identity of the previous being has been carried forth to the future being. Who cares if some body in the future has the same folds in their brain as I once did? Does that mean that I can truly expect to sense what that body will sense?
The answer is no.
These conclusions follow simply from what Russell wrote over a 100 years ago. And the JWs are still using the same reasoning Russell used today. I wonder why the JWs appear to be satisfied with such a superficial and, as you pointed out, non-Biblical view of the nature of the resurrection.
