Krauss (sort of) Recants

Warren Dunes State Park, SW Michigan

Physicist Lawrence Krauss has become more famous than ever for his non-scientific claim that:  “Philosophy is a field that, unfortunately, reminds me of that old Woody Allen joke, ‘those that can’t do, teach, and those that can’t teach, teach gym.' And the worst part of philosophy is the philosophy of science; the only people, as far as I can tell, that read work by philosophers of science are other philosophers of science. It has no impact on physics what so ever. ... they have every right to feel threatened, because science progresses and philosophy doesn’t.”

Last week philosopher Massimo Pigliucci counter-attached Krauss. Pigliucci is both brilliant and funny; therefore he is brilliantly funny (that statement is logically false, committing some kind of informal fallacy). From Pigliucci's "Lawrence Krauss: another physicist with an anti-philosophy complex" :
  • Krauss calls philosopher David Albert a "moronic philosopher." Pigliucci writes: "Still, I wonder if Krauss is justified in referring to Albert as a “moronic philosopher,” considering that the latter is not only a highly respected philosopher of physics at Columbia University, but also holds a PhD in theoretical physics. I didn’t think Rockefeller University (where Albert got his degree) gave out PhD’s to morons, but I could be wrong."
  • "The reason physicists such as Weinberg, Hawking and Krauss keep bashing philosophy is because they suffer from an intellectual version of the Oedipus Complex (you know, philosophy was the mother of science and all that... you can work out the details of the inherent sexual frustrations from there)."
  • "The business of philosophy (of science, in particular) is not to solve scientific problems — we’ve got science for that (Julia and I explain what philosophers of science do here). To see how absurd Krauss’ complaint is just think of what it would sound like if he had said that historians of science haven’t solved a single puzzle in theoretical physics. That’s because historians do history, not science. When was the last time a theoretical physicist solved a problem in history, pray?"
  • "And then of course there is the old time favorite theme of philosophy not making progress. I have debunked that one too, but the crucial point is that progress in philosophy is not and should not be measured by the standards of science, just like the word “progress” has to be interpreted in any field according to that field’s issues and methods, not according to science’s issues and methods. (And incidentally, how’s progress on that string theory thingy going, Lawrence? It has been 25 years and counting, and still no empirical evidence...)"
  • "Krauss also has a naively optimistic view of the business of science, as it turns out. For instance, he claims that “the difference [between scientists and philosophers] is that scientists are really happy when they get it wrong, because it means that there’s more to learn.” Seriously? I’ve practiced science for more than two decades, and I’ve never seen anyone happy to be shown wrong, or who didn’t react as defensively (or even offensively) as possible to any claim that he might be wrong. Indeed, as physicist Max Plank famously put it, “Science progresses funeral by funeral,” because often the old generation has to retire and die before new ideas really take hold. Lawrence, scientists are just human beings, and like all human beings they are interested in mundane things like sex, fame and money (and yes, the pursuit of knowledge). Science is a wonderful and wonderfully successful activity (despite the more than occasional blunder), but there is no reason to try to make its practitioners look like some sort of intellectual saints that they certainly are not (witness also the alarming increase in science fraud, for instance)." (I know I'm quoting a lot, but these are so funny, and true. Therefore they are truly funny (another informal logical fallacy).
Yes, Krauss has published a (sort of) recantation, a quasi apology. It's here - "The Consolation of Philosophy." To which Pigliucci responds:

"Postscript: As people have pointed out, Krauss has issued an apology of sorts, apparently forced by Dan Dennett. He still seems not to have learned much though. He confuses theology with philosophy (in part), keeps hammering at a single reviewer who apparently really annoyed him (in the New York Times), and more importantly just doesn't get the idea that philosophy of science is NOT in the business of answering scientific questions (we've got, ahem, science for that!). It aims, instead, at understanding how science works. Really, is that so difficult to understand, Prof. Krauss?"
