Caught in deep thought

[Mr.Obvious]

But wouldn't your persona be completely removed of the one you have now?

Let's say the my idea was true we would have lived multiple lives up till now without remembering anything. We would when we are born are just a blank slate 
our persona if you will is ours to mold and shape into the person we want to become with the exception outside  influences I.E. religious indoctrination and such.

Ah, now I understand. I disagree. But I understand.

I don't think our persona, or soul or whatever we call it in this context, exists freely. It's an emergent property of our brain which is defined by nature, i.e our biogenetic make-up, which is then molded by said outside influences. Unless you were to say your previous lives had your DNA, I don't see this as viable.

And even if it were so, the merrit of the entire deal would still elude me. But hey, that's just me.
