Agatha,
- I don't understand the inclusion of that last sentence -- my hypothetical does not include any changes to the DNA. Dave says that an exact recreation of my DNA, and even the first three years of my life, would produce a copy of me, but not me.
Thank you for replying, I appreciate it.
An exact reproduction of you is a copy of you. An exact reproduction of a famous painting (down to individual brush strokes) is a copy, not the original. An exact reproduction of a cake is a copy of a cake. In each case, you end up with two identical but separate persons/paintings/cakes. These aren't exact analogies as paintings and cakes are not people.
Now in the case of reproducing a person, this isn't actually possible so we are talking theoretically. But supposing we could reproduce you, together with your memories and experiences, then at the moment of replication there would be one 'you' and one identical copy of 'you' - and nobody, not even the two 'yous' would be able to determine which 'you' was the original and which the copy. Each one would believe themselves to be the original, but they still have two separate consciousnesses.
Those two separate but identical consciousnesses are both you, one is original, one is a copy and they cannot be distinguished. After the moment of reproduction, the two selves would immediately begin to diverge and become more and more different. However, this would not help identify the original from the copy.
However, as I said, this is theoretical as in the real world, such reproduction is impossible. Even identical twins have different observations and experiences in the womb.
Back in the real world where such reproduction of self is impossible, what bearing does this have on the likelihood of immortality or any kind of continuation of consciousness after death?
Perhaps the most important question to ask is if consciousness were to be reborn in another person, which I think is your claim, but without any memory of the previous life, in what way could this be distinguished from the scientific understanding of consciousness permanently ceasing to occur following the death of the brain?
