Dobzhansky said "Nothing in Biology Makes Sense Except in the Light of Evolution", and I would borrow that expression and say, "Nothing anywhere makes sense except in the light of realism".
Yes, what a fool Leibniz must have been for thinking Newtonianism, arguably the most successful scientific theory in history, merely a good tool for predicting the motion of bodies, rather than being The Truth of Reality. Oh wait...
Actually, Putnam's "no miracles" argument (scientific realism "is the only philosophy that doesn't make the success of science a miracle") commits the base rate fallacy and ignores another (IMO, very plausible) explanation (namely, the "natural" selection of scientific theories).
Metaphysical realism != realism about particular theories
BTW: do you know of any good sources arguing in favour of the Darwinian explanation of the success of science (other than van Fraassen)?
From Being a Realist (even if you believe in God):
My mother, who doesn't call herself a theist (I think she's agnostic), doesn't even accept realism. She doesn't even agree with this:
That's little more than tautologies here. Yet it elicited an impression of being forced to believe. I know because she told me about the totalitarian dangers from such narrow thinking.
I'm happy to have finally found the root cause of our ongoing disagreement, but now, how can I deal with that? It looks pretty hopeless, but just in case, does someone have a suggestion, or should I just leave it at that? (My ego doesn't like it, but giving up is an option.)
Now I'm relieved to know that in near mode, she's a complete realist. This craziness only shows up in far mode.
