Unlike some epistemologists well known in science education, usually coming from the physical sciences and mostly rationalists, Maturana comes from the biological sciences and tries to explain knowing by explaining the knower and taking as starting point the observer's experience and the observation. This knower cannot distinguish, in his/her experience, between illusion and perception, but he/she can generate explanations of the experience, which are reformulations of the experience. Scientific explanations, for instance, are reformulations of experience accepted by the scientific community because they satisfy validation criteria established by the community itself. This paper attempts to clarify these ideas.
