 According to eliminativism, once folk psychology is overthrown, strict scientific usage will have no place for reference to most of the entities postulated by folk psychology, such as belief. Beliefs, then, like “celestial spheres” or “phlogiston”, will be judged not actually to exist, but rather to be the mistaken posits of a radically false theory. We may still find it convenient to speak of “belief” in informal contexts, if scientific usage is cumbersome, much as we still speak of “the sun going down”, but if the concept of belief does not map onto the categories described by a mature scientific understanding of the mind, then, literally speaking, no one believes anything.
