Evolution vs. Naturalism ...

... Why they are like oil and water. (Hat tip, Dave Lull.)

Suppose the adaptive neurophysiology produces true beliefs: fine; it also produces adaptive behavior, and that's what counts for survival and reproduction. Suppose on the other hand that neurophysiology produces false beliefs: again fine: it produces false beliefs but adaptive behavior. It really doesn't matter what kind of beliefs the neurophysiology produces; what matters is that it cause adaptive behavior; and this it clearly does, no matter what sort of beliefs it also produces. Therefore there is no reason to think that if their behavior is adaptive, then it is likely that their cognitive faculties are reliable.

Then there's this: Darwin to the Rescue.

But, as Platinga notes:

... what evolution tells us (supposing it tells us the truth) is that our behavior, (perhaps more exactly the behavior of our ancestors) is adaptive; since the members of our species have survived and reproduced, the behavior of our ancestors was conducive, in their environment, to survival and reproduction

Then literary Darwinism can only demonstrate this over and over again.
