Tanasije, I’d say “Quinean empiricism” plus scientific realism (if I may sum those two) gives you physicalism, or something near enough. In any case, what is “supervenience” if not an account of what metaphysical naturalism is, on the one hand, or an explanation for the success of methodological naturalism, on the other?
(Yes, some scientists are in a sense metaphysically pluralist, since they grant or pressuppose the nonmateriality of abstract objects like mathematical entities or theories [profigately, in my view]. The point here, though, is that with respect to the phenomena they study as scientists, they presuppose physicalism.)
I like this bunch. Here’s a Bertrand Russell quotation I’m fond of: “A stupid man’s report of what a clever man says can never be accurate, because he unconsciously translates what he hears into something he can understand.”
