Platonic epistemology
In philosophy, Plato's epistemology is a theory of knowledge developed by the Greek philosopher Plato and his followers.
Platonic epistemology holds that knowledge of Platonic Ideas is innate, so that learning is the development of ideas buried deep in the soul, often under the midwife-like guidance of an interrogator. In several dialogues by Plato, the character Socrates presents the view that each soul existed before birth with the Form of the Good and a perfect knowledge of Ideas. Thus, when an Idea is "learned" it is actually just "recalled".[1]
Plato drew a sharp distinction between knowledge, which is certain, and mere true opinion, which is not certain. Opinions derive from the shifting world of sensation; knowledge derives from the world of timeless Forms, or essences. In The Republic, these concepts were illustrated using the metaphor of the Sun, the analogy of the divided line, and the allegory of the cave.
