I think it would probably not be much of a problem if we're talking purely about genetic clones, but if it were possible to clone a person as they are right now, including the current state of their mind and memories and so forth, it seems like this could be very difficult to reconcile. I think if I knew I was the original and my clone knew he was the clone, it might be, if I was thinking from the clone's perspective, as though I could "start from zero," with no belongings, no wife, no nothing. I think that if I were said clone I'd actually find that pretty exciting, it'd be like the same person could live a whole other life. After a few months went by, depending on the relative fortunes of the original and the clone, I guess either a friendship would ensue but hopefully not jealousy. It would definitely be weird.
