[Avodah] Free Will vs. Physics

[Moshe Y. Gluck]

A friend of mine put on his Facebook status: ______ wants to know whether there is free will or only physics.

I wrote this to him, any comments?

Obviously, this is a topic that has been hashed and rehashed by many people lots smarter than me, so I doubt I'll add anything to what you already know about the topic. But if you want to know my personal reasons for believing in free will vs. physics, here goes:
First off, believing in free will doesn't mean believing that physics has no effect on a person's choices, just that there are also choices that a person makes independent of physics. I don't have any theological problem with that - presumably it is all toted up correctly, weighted properly, in the big accountant's office up there. 
Second, I believe that Hashem exists and runs the world and gave the Torah, which clearly says that we have free will (U'vacharta B'chayim.). 
Third, seems to me that if everything ran according to physics, much of it would be totally random. If the world was random, seems to me that randomness leads to destruction and disorder. The world is a very ordered place, with many things in it operating along specific mathematic formulae like fractals and the Golden Ratio. It works very dependably and predictably. It doesn't seem random at all. So if I assume that everything is physics, then I would have to assume it was random, and if it was random, it should be totally unstable and destructive. And, in the main, it isn't. 
I don't know how much proof this is, but if you look at people who clearly are not in control - schizophrenic, bipolar, depressed - you see that a lot of their behavior is destructive (that's in my experience with such people - I haven't studied the literature). That fits my theory - their brains are not running - to a much greater degree - on free will, and that's why their behavior is much more destructive. Take it or leave it. :-)
