Well, he's partially correct. You don't study the philosophy of science (or philosophy for that matter) because of some utility it has in relation to something else (here, empirical science). You study it for its own sake. That's what theoretical sciences (including philosophy, though ethics is also practical) are about, truth for its own sake. That philosophy may have a beneficial influence on the practice of science is not negated, but it's important to understand the primary aim. As far as quotes are concerned, here's one from Feyerabend that explicitly names Feynman: "The withdrawal of philosophy into a 'professional' shell of its own has had disastrous consequences. The younger generation of physicists, the Feynmans, the Schwingers, etc., may be very bright; they may be more intelligent than their predecessors, than Bohr, Einstein, Schrödinger, Boltzmann, Mach and so on. But they are uncivilized savages, they lack in philosophical depth" In other words, the ignorance of philosophy so prevalent among scientists has rendered them a class of boorish technicians. And it seems to be getting worse. Just look at Lawrence Krauss and friends.
