I'm a paid philosopher, and I didn't see this mentioned so I thought I'd make it clear: Feyerabend is not a typical philosopher of science. The vast majority of philosophers of science (in the majority "analytic" tradition, anyway) take real science and its successes very seriously. Feyerabend was a deliberate provocateur, and it isn't even clear how seriously he took his own arguments; some suspect he was just pushing devil's advocacy to see how far it would go.
For those who think there is no place where philosophy can inform science, you should let the rest of us know how you already solved problems crucial to science, like the nature of measurement, why we pick simpler theories (and how precisely you measure simplicity), the line between science and pseudo-science (it is not "falsification" - at least, not straightforwardly), the apparently privileged direction of time, the source and nature of physical laws and causation, the nature of explanation, etc. We poor struggling philosophers would really like to know.
