Determinism Is Self Defeating

[Red Celt]

The point that I'm making is that as a theory determinism can only be proven by making accurate predictions, the rock rolling down the hill for instance.
Until that time it can only be regarded as a hypothesis.

Or are we just going to toss the concept of scientific scrutiny out the window?

The burden of proof would be in your hands. Extraordinary claims require extraordinary evidence. Prove non-determinism. Show us the non-material hand altering the path of the billiard balls.

Try re-reading what you posted, while replacing "determinism" with "evolution"... and you might see how your position looks to a determinist.
