Feyerabend's Metaphysics: Process-Realism, or Voluntarist-Idealism?

John Preston has contended that Paul Feyerabend retreated from his earlier commitment to realism and consciously embraced a ‘voluntarist’, social constructionist, idealism. Though there seems to be unmistakable subjective idealist statements in some of Feyerabend's writings, it will be argued that Feyerabend's idealistic period was short-lived, and that he returned to a form of realism in his later writings. Specifically, Feyerabend's distinction between theoretical/abstract and empirical/historical traditions of thought, when understood with Feyerabend's re evaluation of Bohr's philosophy of quantum physics in mind, is most aptly interpreted as aprocess realist position. Preston, in interpreting Feyerabend as a voluntarist, social constructionist, subjective idealist, fails to distinguish the ever-present rhetorical and provocative statements of Feyerabend's from the core arguments being presented.
