James Blachowicz, professor emeritus of philosophy with a focus on the philosophy of science according to his Loyola page wrote "Of Two Minds: The Nature of Inquiry". I found 51 references to Popper searching the book on Amazon. I'm not a philosophy expert, but based on this article and wikipedia information about Popper and falsifiability, I'm going to go out on a limb and suggest this guy actually knows what he's talking about and perhaps some of the commenters here aren't up to date on the science of philosophy issues he is addressing.
