 Such an epistemology, Feyerabend now complains, makes the false assumption that “rational” standards can lead to a practice that is as mobile, rich and effective as the science we already have. Falsificationism would destroy science as we know it. Science did not develop in accordance with Popper’s model. It is not “irrational”, but it contains no overarching pattern. Popper’s rules could produce a science, but not the science we now have. (Feyerabend remarks that the Logical Positivist Otto Neurath had already put this criticism of Popper some time before (p. 91)).
