> theoretically, everything could be reduced to physics

Is there a thing as free will, and if so, is it explainable in terms of physics? And with consciousness (if you believe there is such a thing)? Is morality and ethics reducible to physics as well? There's a lot of presuppositions to the statement that everything is reducible to some purely mechanical process.

I have no doubt that many serious people believe as you have stated, but it's not a self evidently true claim.
