"The intuitive appeal of a scientific theory has to do with how well its metaphors fit one's experience." #readingToday

So-called purely intellectual concepts, e.g., the concepts in a scientific theory, are often— perhaps always— based on metaphors that have a physical and/ or cultural basis. The high in "high-energy particles" is based on MORE IS UP. The high in "high-level functions," as in physiological psychology, is based on RATIONAL IS UP. The low in "low- level phonology " (which refers to detailed phonetic aspects of the sound systems of languages) is based on MUNDANE REALITY IS DOWN (as in "down to earth"). The intuitive appeal of a scientific theory has to do with how well its metaphors fit one's experience.
