Paul like Bill G have no free will because
classical physics is fully deterministic. Whatever happened just after the birth of the universe has to play out in a fully predictable way as demanded by classical laws. That is an extension of what Sabine's is arguing.
What you have to do in classical physics is inject chaos as a theory and give "conscious" a special role to sort of create a degree of pseudo-random world you would then see around you. This all dates way back to arguments around in the 1800's and some people revive it from time to time.
For you Bill S with your understanding, there exists a falsification of all this rubbish and it's called superfluidty (
https://en.wikipedia.org/wiki/Superfluidity). In the article it will give you the problem that it can't be described by classical physics because it defies classical gravity and surface tension. You will see science later added Bose-Einstein condensates to this category.
So now you have something that doesn't involve chaos or conscious and yet completely defies classical physics description, showing they are at best incomplete and not fully deterministic. This was the start of how science realized it was going to be able to peel apart the classical laws one by one you just need to create the right experiment.
Pyotr Kapitsa was given the Nobel prize for his work and the significance on the subject.
It takes just one observation
