This school of thought, which considers the relation between knowledge and reality (epistemology) within an evolutionary perspective, posits that an organism is never able to recognize, depict, or mirror reality, and that it can only construct a "model that fits" (Glaserfeld, 1984). This model (paradigm/model/map) evolves in the organism's interactions with its environment and obeys evolutionary principles of selection.
