Free will and the necessary evil

[Jehanne]

Metaphysical ideas are not testable, which means that they will never rise beyond the level of conjecture.  I could claim the Cosmos is eternal and uncaused, pointing to peer-reviewed papers in The Physical Review Letters to support that POV, while others will appeal to "God did it".  The former claim can be modeled, and, perhaps, even tested; the latter claim, even if true, is not testable barring God's participation in some controlled and observable experiment (say, a randomized, double-blinded prayer study or the spontaneous healing of an adult amputee or something similar).  And, so, metaphysicians disagree with one another, some atheistic and others theistic with still others deistic and pantheistic and no mechanisms exist to adjudicate the disagreements amongst them.

I'm not following you. Even if that were true, what does that have to do with anything?

All scholars agree that the findings of modern physics has had a significant impact on modern philosophy over the last century; the opposite is, however, not true. Physicists do not care what philosophers think, except when they are trying to be polite about not caring.
