Personally I subscribe to the view that the world is not deterministic primarily because of feedback, if the result can influence the input then it seems to imply that the result is not predetermined.

I wondered if one can consider freewill as an example of feedback. The brain provides the feedback by predicting, what is likely to happen based on previous examples, and thus suggests a course of action, for example we have a choice when we step off the curb as to timing, and we know from previous experience (feedback) that stepping in front of a car is not desirable. Looking at the question from this point of view the brain is simply providing the best feedback it can, to insure ones survival whether it is avoiding being knocked over by a car or finding the best source of food.

warmair, determinism doesn't imply predetermination, merely that causes and effects are linked by some set of necessary and ultimately understandable rules of behaviour. A system with feedback is entirely analysable in deterministic terms - that is the whole basis of digital circuit design, which relies on op amps with feedback. However, that analysis becomes very difficult in highly complex systems

I've previously mentioned the work that Deutsch and Marletto are doing on constructor theory. That is an attempt to produce a coherent theoretical basis for science, starting at fundamental physics which is of course where everything starts, to replace the somewhat ad hoc empiricism that has driven most of our scientific endeavour to date. The fundamental basis for that model is determinism.
