Bet you can't. You can't prove that you're really you. EDIT: Stop using the argument "I think, therefore I am." argument. It does not present facts. EDIT 2: 1000 posts and still no proof. C'mon Flood! EDIT 3: Stop asking me to prove [i]my[/i] existence. That's not the point of this thread. EDIT 4: I know that there are actual theories and beliefs that we are all(or, more correctly, one or a handful of us) just an intelligence and everything else is a projection in a dream state. This argument that I have used in no way represents my views or beliefs.
