Will the Popperian Feyerabend please step forward: Pluralistic, Popperian themes in the philosophy of Paul Feyerabend

John Preston has claimed that we must understand Paul Feyerabend's later, post-1970, philosophy in terms of a disappointed Popperianism: that Feyerabend became a sceptical, relativistic, literal anarchist because of his perception of the failure of Popper's philosophy. I argue that this claim cannot be supported and trace the development of Feyerabend's philosophy in terms of a commitment to the central Popperian themes of criticism and critical explanatory progress. This commitment led Feyerabend to reject Popper's specific methodology in favour of a pluralistic methodology, but the commitment to the central values of criticism and critical explanatory progress remained . Moreover, methodological pluralism does not imply scepticism, relativism, or literal anarchism. Feyerabend was not a disappointed Popperian, but, in many respects, a die-hard pluralistic Popperian.
