Dewey's pragmatism rejected ‘truth’ as indicative of an underlying reality, instead ascribing it to valuable connections between aims and ends. Surprisingly, his argument mirrors Bishop Berkeley's Idealism, summarised as ‘esse est percepi’ (to be is to be perceived), whose thinking is shown to be highly pragmatist—but who retained a foundationalist ontology by naming God as the guarantor of all things. I argue that while this position is unsustainable, pragmatism could nonetheless be strengthened through an ontological foundation. Koopman's charges of foundationalist (...) ‘givenism’ in Dewey's work, and in his promotion of the scientific method, are not proven. However, Koopman's ‘genealogical pragmatism’ may develop Deweyan educational theory by addressing dilemmas around curricular study. Koopman's arguments also point towards a missing ontological piece in Dewey's theory of knowledge. In the final section of the article I offer a dialogic ontology as compatible with pragmatism. This dialogical ontology provides both an ethical foundation through interrelatedness, and a generative theory of meaning and experience, as emergent from the encounter with difference. In this framework, to be is to respond—or be responded to. I offer the metaphor of ‘realisation’ to capture the human experience implied by this ontological stance. (shrink)
