Playing devil's advocate is useful. One has to consider the other side as well. I suppose I am doing something smilar, but I am not interested in showing you are a fanatic or even wrong. I just want to clarify what I think is the case.
Sometimes we think we can list all the possibilities and then eliminate those that don't work. The last possibility remaining must then be true. That is an effective approach provided we have actually listed all the possibilities. Usually we are too blinded to do that.
Non-determinism contains a lot of possibilities. It is not just the butterfly effect which I think is too deterministic for even chaos theory. For example is the hurricane so determined that only the random change in a single butterfly will determine if it exists or not? It would seem that chaos theory needs a lot more randomness than that.
Although I have Gleick's book I have not read it. I am reading Bergson's "Creative Evolution" at the moment. However, I wouldn't mind learning more about chaos theory when I get back to Chicago.
If chaos lies between full determinism and full randomness then it is not how I view reality. Reality contains neither determinism nor randomness as I see it so there is no way for reality to be some middle ground between a little bit of determinism and a little bit of randomness. Reality contains various forms of subjective consciousness making choices under constraints. At least, that is how I see it.
Models and simulations on the other hand (not reality) can contain various forms of determinism and randomness. And these models can be very useful, but they are not reality. They just model reality. Constructing models is a scientific activity based on experimental testing whose accuracy is limited by the precision of the instruments available for the tests. Claiming that reality is the model or simulation is metaphysics, not science. To confuse reality with a simulation of reality is like confusing a meal with the menu, to use an old saying.
That is close to what I am saying. However, people might argue that we do not have complete free will and we don't. We are somewhat predictable based on our "dispositions". But we have enough free will to make a choice which allows something new and intentional to appear.
You mentioned Penrose and Hameroff's quantum vibrations. These could be accepted as correlates of consciousness in humans. They are sometimes easier to work with than saying consciousness implies the existence of choice. It might not be easy to show that a choice was made. Suppose one accepts that finding these quantum vibrations implies that the being having them was conscious. It is easy to find these quantum vibrations. Then we could see what other species also had quantum vibrations and say they too are conscious. That is where I see the usefulness of correlates of consciousness.
Some people look at correlations differently. They find a correlate of consciousness and think they can reduce consciousness to that correlate. That would be like finding a footprint in a forest (a correlate of some animal walking in the forest) and claiming the footprint made the animal rather than saying that the animal made the footprint.
