Paul K. Feyerabend was a sceptical master and iconoclast about the philosophy
of science. He denounced the break between the abstract, normative, philosophical
accounts of science and the actual, complex and context-dependent scientific
practice. Feyerabend’s first iconoclastic enterprise was directed against
philosophical empiricism: roughly, the view that what is to be believed is what experiences
establishes, and no more. In fact, Feyerabend’s line of attack is broad
and applies to any foundationalist epistemology. A naïve appeal to experience assumes
that what experience delivers is evident and unequivocal, and thus scientific
theories can be grounded on independently meaningful observations. To Feyerabend,
this view is at variance with actual scientific practice. Empiricism in the
form in which is theorised by some Logical Empiricists philosophers cannot fulfil
the hope of the progress of knowledge; on the contrary it is bound to lead to
“a dogmatic petrifaction” of theories and “the establishment of a rigid metaphysics”
