Plato's Theory of Knowledge


Plato’s Theory of Knowledge is very interesting. He expresses this theory with three approaches: his allegory of The Cave, his metaphor of the Divided Line and his doctrine The Forms.

Plato states there are four stages of knowledge development: Imagining, Belief, Thinking, and Perfect Intelligence. Imagining is at the lowest level of this developmental ladder. Imagining, here in Plato’s world, is not taken at its conventional level but of appearances seen as “true re...
