4Allegory of the Cave From the Republic by Plato Translated by Benjamin Jowett The Allegory of the Cave, or Plato's Cave, was presented by the Greek philosopher Plato in his work the Republic to compare "the effect of education and the lack of it on our nature". The allegory is probably related to Plato's theory of Forms, according to which the "Forms", and not the material world known to us through sensation, possess the highest and most fundamental kind of reality. Only knowledge of the Forms constitutes real knowledge or what Socrates considers "the good". 5] Socrates informs Glaucon that the most excellent people must follow the highest of all studies, which is to behold the Good. Those who have ascended to this highest level, however, must not remain there but must return to the cave and dwell with the prisoners, sharing in their labors and honors.
