In this paper I examine Peirce's epistemological and ontological theories and indicate their relevance to educational practice. I argue that Peirces conception of Firsts, Seconds and Thirds entails a fundamental ontological realism. I further argue that Peirce does have a theory of truth, that it is a particular non‐traditional ‘correspondence’ theory, consistent with, and implicit in, an over‐arching position of pragmatic realism. Peirce's epistemological position is subject to misinterpretation when the ontological realism on which it rests is overlooked. Finally I (...) suggest that such a re‐consideration of Peirce's pragmatic ontology and epistemology in an educational context is needed. (shrink)
