ok, hopefully we're making progress on understanding each other...
does your brain operate deterministically? that is, if we knew the state of your brain at a point in the past, and all of the input(s) that had entered it since then, could we accurately predict your decision to get up and get the coke?

Well, I got sidetracked. I saw my unmade bed and remembered my sheets are in the dryer. Good thing I checked because they were still damp. Anyways, long story short, I got a glass of cold water instead of the Coke.
My brain receives a lot of input. What I decide to do is very much dependent on outside factors and internal physiological cues. Things change, however, if I suffer a stroke or some other brain injury. My mother has Alzheimer's. Her short term memory is gone and her long term memories are fast disappearing. She still knows us, but is incapable of caring for herself. Thankfully she still remembers how to feed herself -- for now, but already her personality has changed. She is not the mother I remember from even a few short years ago. Once the disease has run its course she will be completely gone even though her physical self remains. Without our brain function we are nothing. One wonders how it is that believers think the personality and memories will return in death.
I don't know how the brain formulates my awareness of self and gives me emotions, but I know that it does for I have seen what happens when that function is stripped away. One day all will be made clear. One day science will possess the answers.
