I guess what I meant was, is there a way for us to control these neurons and quarks moving around that affect things, or are we controled by them.
Say a neuron fires prompting the muscles in my leg to spasm and kick someone in the face, did I make the neuron fire, or did it happen randomly?
Yeah, that's the question. For the leg-kick I'd say it was not determinate, but a very long progression of indeterminate actions from your birth or prior, possibly to the beginning of the Universe. Not that we control it, but that at the time of our birth (for an example of a timestamp) it was perhaps up in the air that it would happen. A series of decisions we (and other sentients or chaotic particles in the Universe) made led to our leg/nerves being in that state at that time and it happened.
If you roll a boulder off a cliff, you can predetermine with near certainty (if the Universe doesn't do anything crazy) that it'll hit the bottom. Get closer to the bottom, or less time, and you can determine the landing spot more accurately. Get further away and your prediction goes more awry. Get WAY far away, and something in the Universe might happen unexpectedly to thwart it even hitting the bottom. Perhaps a sapling grows into a tree and the tree falls between the boulder and the spot it would've hit.
Even if you push it from one foot though, while you can say it'll certainly hit the bottom, and be very accurate in the spot, you can't tell exactly the spin, the particles breaking off, etc. I'd liken that to our leg tic--the further back in time we go the harder it is to determine exactly where it'll "land", if it lands at all. It could be impossible at some point back, or it could be impossible to determine precisely where it'll be at any point, even a millisecond back may provide more than enough chaos to make it non-predetermined. The question then is--how long a drop is it, between event A and event B, according to the substrate of Universal determinist/nondeterminist qualities?
The Universe seems orderly and chaotic at the same time, but of different quality depending on how micro or macro one gets. This is the analogy I see that still gives us free will within a chaotic but fairly orderly Universe. Even if we don't have free will, perhaps a micro quality of our perceptual thought process does, in that it's nondeterminate. Or perhaps our thoughts themselves are the time-stamp of predeterminism, but as they cascade and are themselves chaotic, we're constantly shifting the time-stamp.

Oh and Palpitus, I would be interested in what you think of Heisenburg's uncertianty principle :)
I've heard of it but don't know what it is. Is that the one with the cat in the box? I'm just a pseudo-philosopher, if that's not readily apparent. ;)
