Sometimes "Newton's Challenge" gets resisted by philosophers. Here's an interesting and prominent example:
"...maybe the lesson of Bell's theorem is exactly that there are physical entities which are unlocalized, and which therefore might make a difference between worlds--worlds in the inner sphere--that match perfectly in their arrangements of local qualities. Maybe so. I'm ready to believe it. But I am not ready to take lessons in ontology from quantum physics as it now is. First I must see how it looks when it is purified of instrumentalist frivolity, and dares to say something not just about pointer readings but about the consitution of the world; and when it is purified of doublethinking deviant logic; and--most of all--when it is purified of supernatural tales about the observant mind to make things jump. If, after all that, it still teaches nonlocality, I shall submit willingly to the best of authority."--David Lewis Philosophical Papers, V2, introduction xi
Given the way I have formulated "Newton's Challenge," I just love Lewis' terminology ("submit," "authority"," "lessons in ontology," etc.)!
In a fascinating recent plenary lecture at BSPS in Norwich, Simon Saunders claimed that with the theory of decoherence, Quantum Mechanics now meets Lewis' challenge. If Saunders is right then philosophers of science have a club to beat the metaphysicians.
