Maybe it works a little better that way, but it still has plenty of holes.
Of course, the first thing I´d ask for would be a definition of "natural".
several definitions work... "that which is governed by cause and effect" is the simplest. You could probably add "temporal" to that definition because as far as i know cause and effect requires time to work.
We don´t have a problem defining god into existence, mind you. I just have to prove that there is a monitor on my desk and then say "and we call this monitor god" and - poof - atheism and agnosticism are refuted.
You're right, it's all semantic nonsense. If I took a stricter definition of God I'd call myself an atheist. anyways...
I think the mind/body problem is actually a stronger argument for the existence of the super-natural.
If "free will" exists, then every conscious action is it's own uncaused cause. That is to say, either your mind is governed entirely by the deterministic/probabilistic chemical reactions in your brain, or it isn't and we actually do have free will.
As far as I can tell, free will does exist. I
seem to be perfectly in control. Or maybe it's all a trick, who knows?
It seems possible, and this is probably the only scientific hypothesis, that everything going on in my head is actually probabilistic and i'm simply watching a movie script of my own actions, only thinking that i'm in control. The problem is this still doesn't nullify the existence of the Mind apart from the body, because even if, I, the observer, am not in control, I, the observer, still exist to observe.
The First Cause argument focuses on why the universe exists, which is impossible to answer as far as i can tell. The mind/body problem is another impossible to answer question as to why anyone is able to consciously observe and interact the universe.
And i don't think this problem will ever be resolved, it's not like we can build a big telescope and discover that the universe has a Main() function or a user interface.
