Context: Johnson argues that because radical constructivism requires social constraints and therefore ontological assumptions, it is no different from constructive realism, which is comparatively mainstream. Results: While the distinction between these approaches appears slim, our concepts are not independent of us, and may need to change in spite of established traditions. Implications: Perhaps radical constructivism cannot be mainstream because it is essentially concerned with epistemological origins of concepts and consequently is not practical enough for the received consensus.
Key words: epiphany, reality, social, testimony
