Plato's Republic — The Allegory of the Cave

Watch on YouTube

Overview

Chapter 8 begins Part Two of the course by applying the philosophical tools to Plato's Republic Book VII — the Allegory of the Cave. Dr. Bannon reads this as a text about education (paideia) and its effect on our emotional and moral state (pathos). The allegory traces two metanoias (conversions): first turning away from the shadows, then — crucially — returning to liberate others. This chapter also introduces Plato's primary source text; see the Allegory of the Cave reading page for Dr. Bannon's full reading of the text.

The Prisoners and the Shadows

Prisoners chained in a cave since childhood can only see shadows projected on the wall in front of them. They name the shadows, debate about them, and take them to be reality. This is Plato's image of ordinary human existence — shaped by media, convention, and unexamined belief.

Metanoia: Turning and Returning

The freed prisoner: first turns around (first metanoia) and sees the fire and the objects — reality, not shadows. Then goes up out of the cave into sunlight (second metanoia) and sees reality in its fullness. But the main point is: they must go back down. Those who have seen the sun are responsible for going back to free others.

Attention is a Commodity

In the modern cave, the 'shadows' are the images on screens. The captors of modern caves are those who profit by capturing and selling human attention. The first metanoia: turn away from the screen toward the thing itself.

Exam Prep Questions

  1. Describe the setup of Plato's Allegory of the Cave. Who are the prisoners, what do they see, and what does this represent philosophically?
  2. What are the two metanoias in the Cave Allegory? Why does Dr. Bannon say the second one is Socrates' main point?
  3. What does Plato mean by 'aletheia'? How does this concept of truth connect to the cave allegory?
  4. What is the 'psycherion' (little soul), and how does it contrast with the 'whole soul'?
  5. What does Socrates say about education (paideia)? How is Plato's definition of education different from the idea of 'filling an empty vessel'?
