@glasstrees,
What happens to my consciousness if my brain is copied ? Is my consciousness only a result of my brain functions ? I would say:
My consciousness is more than only my brain functions.
To explain this the thought experiment of the copying of my brain can be used:
Common view is, that my conscious I is a result of only my neural functions in my brain. This means, that sometime during the evoultion of life a set of functions came together and my I was formed. Now lets assume we understood all physical functions that are going on in my brain and we can make a copy of them. What happens then ?
Common view is that then another consciousness is arising which is different from mine. But this is a contradiction in itself.
I explain why:
If my I is only a result of physical functions then everytime these functions occur they have to result in my I. They cannot result in another consciousness because this would violate the first assumption that theses functions alone define my I. If there arises another consciousness after the copying process this would mean that the same functions result in different I?s. But then these functions are not enough to define my I.
To keep the first assumption we could say that after the copy process I
would have more than one I. But this makes no sense, I can only have one First Person View and one experience. My I would never change no matter what someone does in the room next to me, even if he is putting a copy of my brain together. This would not affect me.
So the only solution to this thought experiment is that physical functions alone can never define my I consciousness. Consciousness must be something outside the physical realm.
I hope I could bring across what I wanted to say, English is not my first tongue.
Thanks,
Elmk
