The fact that you wished for something is born out by the fact that you posted. Even if your post doesn't bear out what you wished for, it probably comes close.
Even the animals have personal identity. How can you tell? There are no two of them that are exactly alike or exist in exactly the same space. However, if you mean soul or spirit, that is something that even science is proving. You are going against the grain of history and recent science if you say there is no soul or spirit.
As usual, you are not making any sense. What does personal identity has to do with made up concepts like soul or spirit?
And you obviously aren't following any scientific research if you think there has been any sort of proof for those vague concepts.
Claiming that i am going against history is just weird nonsense. If you are saying i don't hold much value on belief systems people used to have, that's true.
As history is full of weird belief systems that don't make any sense. They were used to understand cause and effect, and not they have been mostly replaced by scientific method.
The point being shown in parallel universes.
How many times has God gone back to Cause and Effect and tweaked it at the beginning so that present results are different... all because somebody wished it now? So, he got his wish, and doesn't even realize it, because he doesn't remember the way it was, that memory never having been formed in him (in this universe).
We can find starts of proof for soul/spirit right in parallel universe theory. But personal identity wouldn't exist, where one says 'I am', without touching on soul/spirit.
However, there is plenty of research going on, and some of it seems to be producing results.
