Reply #49: I disagree with your point (I think)

I'm not quite sure what your argument is, but if you are saying what I think you are saying, then I disagree.

The uncertainties caused by nonlinear systems are not in the physical system itself, but in our models of those systems. The physical world just "is" - there is no uncertainty. We can build proper and correct models of these systems (we have for many examples) but the problem is as your quote above states - that the inaccuracies present in a model prevent us from deterministically predicting future behavior of the real system with the model. We can use Monte Carlo methods to get an idea of where the real system might go, but that is not the same as a deterministic prediction.

But this does not invalidate the idea that the physical world is non-deterministic, it only supports the theory that we cannot predict that deterministic path.
