When you confine yourself to different subsets of the universe, you can establish how some phenomena work but it will always be limited scope and not bring full understanding.

What I was talking about is basic principles. If we have absolute determinism according to a set of laws, then we get certain result without ability of the system to change itself or it’s way of (non-)development. Thus no free will possible. Unless there is an external force. But we already assumed we are talking about everything that exists without limitations and no matter how meager the effects of different laws to different parts of the system are.

On the other hand, if we assume Universe is non-deterministic, then we must admit some laws of energy/space/time interactions do not always work. Which is also a strange idea.

I’m not promoting some particular theory. I’m just writing about high level consequences of some fundamental assumptions that we make when creating our models. As an inspiration for the thought.

Or maybe another idea — that it is impossible to describe rationally how Universe works because explanation is outside rational scope. Thus any rational explanation would result in a contradiction at some point.
