Chaos, the Ability to Perceive Options

I promised this thread on another discussion thread and now...I have to deliver.
Just what makes Chaos Magic(k) chaotic?
We are beings with the ability to perceive many things but is Chaos one of them?
How, as organized life forms, are we able to conceptualize Chaos and then produce a 'system' of magic that utilizes this principle? (the idea of a 'system' implies order by its very nature)
A close friend and I are in the middle of this debate...he's a Molecular Biophysisist and I'm a dropout. He claims evidence of chaos exists in many ways and I've asked him to illustrate this. So far I've not heard of anything objective. True, we can say 'chaos' and write 'chaos' but we are doing so with the tools of order.
Let me bow out for awhile and let the over heated air cool and invite ideas from the Forum. Remember, this is a debate/discussion and we should agree to disagree rather than slinging shots! OK? (IMG:style_emoticons/default/huh.gif)

I think that one can definitely learn to perceive the most important aspect of chaos and that aspect is chance. Though I don't think most perceive chance with their eyes, they perceive it through other senses, not that it's impossible to see. The quote 'for the beginners mind there are many choices, for the expert there are few' seems to fit in well with this topic. If you can perceive chance then I think you must be able to perceive chaos but I'm not sure if it's part of human nature to do such a thing.
