I think you completely misunderstood what I said. Your original claim is that your self is entirely synonymous with your brain, and my argument was that if your self is really synonymous with your brain then you and a duplicate of you will be a single conscious being. As we can easily determine that you and your identical twin are different conscious entities, and that if a perfect copy of you is made at any given instant that it will be its own conscious entity, I think it casts some doubt on the claim that your self is entirely dependent on your brain. Sure your ego is, your memories, etc...but I think there is something else that is independent of the brain. Simply because I do not think that a perfect copy of me will really be me. If I die after the perfect copy of myself is created, I will not be seeing through the eyes of my copy. I will not be tasting through the tongue of my copy. But the brain will be the same brain, so I must at some level exist independently of my brain.
