slicer, I've had those exact same thoughts (well not about the book, which I've never heard of but sounds interesting, but on memory loss). this is very much connected with the nature vs nurture debate. the argument over whether a person's behaviour and personality is determined by their environment or their genes. personally I think it's a combination of both, but that a person who has lost their memory (or a clone of a person) will never be exactly the same cause you can't duplicate their life experiences.
