who is speaking in the allegory of the cave
The Allegory of the Cave, or Plato's Cave, was presented by the Greek philosopher Plato in his work Republic (514a -- 520a) to compare "the effect of education (παιδεία) and the lack of it on our nature". It is written as a dialogue between Plato's brother Glaucon and his mentor Socrates, narrated by the latter. The allegory is presented after the analogy of the sun (508b -- 509c) and the analogy of the divided line (509d -- 511e). All three are characterized in relation to dialectic at the end of Books VII and VIII (531d -- 534e).
