Doing away with verifiability hardly means science can't make progress.
Popper is not Kuhn. The more that a scientific theory opens itself to
possible refutation (by making clear and broad claims that can be tested)
and yet continues to survive refutation, the better a theory it is. Popper
no doubt is not complete. Perhaps a better account of scientific progress
needs to be developed on a Popperian basis. (It would be a stimulating
project to combine Churchland's account of scientific progress with
Popper's account of the nature of science.)
