 The interactional, organic model Dewey developed in his psychology informed his theories of learning and knowledge. Given this new ecological framework, a range of traditional epistemological proposals and puzzles (premised on metaphysical divisions such as appearance/reality, mind/world) lost credibility. “So far as the question of the relation of the self to known objects is concerned”, Dewey wrote, “knowing is but one special case of the agent-patient, of the behaver-enjoyer-sufferer situation” (“Brief Studies in Realism”, MW6: 120). As we have already seen in psychology, Dewey’s wholesale repudiation of the tradition’s basic metaphysical framework required extensive reconstructions in every other area; one popular name for Dewey’s reconstruction of epistemology (or “theory of inquiry”, as Dewey preferred to call it) was  “instrumentalism”.[22]
