Representationism
Representative Theory of Perception, also known as Indirect realism and epistemological dualism, is a philosophical concept. It states that we do not (and can not) perceive the external world directly; instead we know only our ideas or interpretations of objects in the world. However, an indirect realist believes our ideas come from sense data of a real, material, external world (unlike idealists). The doctrine states that in any act of perception, the immediate (direct) object of perception is only a sense-datum that represents an external object.This immediately raises a question: How well do sense-data represent external objects, properties, and events? Indirect realism creates deep epistemological problems, such as solipsism and the problem of the external world. Nonetheless, Indirect realism has been popular in the history of philosophy and has been developed by many philosophers including Bertrand Russell, Spinoza, René Descartes, and John Locke.
