ok its late and im a little tired so forgive me if anything i say is already countered in previous arguements here, or if this is just babbling
but here goes
I dont believe in free-will, everything that happens is shown as a choice, is weighed up by previous experience, the enviroment at the time, etc. So if you took a person making a choice about anything, the same choice would be made everytime, given the exact same circumstances, so the illusion of free-will is given, but in atual fact, the outcome was inevitable. Of course, there is no way to prove/disprove as such, as duplicating the entire universe to any given time is impossible.
though thinking about it more it could be possible with enough knowledge of a perticular person/thing to predict what it will do next, this is already done in world, catching criminals etc, it is pridicted they will break for home /friends for instance. Taking this to a new level, if known intimately about a person, every move could be predicted.
I am a athiest and dont believe in any god or soul, as such, brain processes are chemical reactions and electronic signals, nothing more.
This is going into what is intellegence, are we special,, what is a mind, but hopefully ive given you a little insight into my thinking, im very open to critisism as my views on this are still formulating and im keeping a very open mind,
Ill probabily come back to this tomorrow and wonder what the hell i was thinking but hey
