Was Feyerabend a Postmodernist?

This article asks whether the philosophy of Paul K. Feyerabend can be reasonably classified as postmodernist, a label applied to him by friends and foes alike. After describing some superficial similarities between the style and content of both Feyerabend's and postmodernist writings, I offer three more robust characterisations of postmodernism in terms of relativism, 'incredulity to metanarratives', and 'depthlessness'. It emerges that none of these characterisations offers a strong justification for classifying Feyerabend as 'postmodern' in any significant sense. Indeed, what does emerge is that Feyerabend's work was fundamentally informed by a humanitarian vision of the value of science that is, in fact, strikingly modern.
