Plato's Symposium — Diotima's Ladder and the Spirit of Eros

Watch on YouTube

Overview

Chapter 9 turns to Plato's Symposium and the remarkable figure of Diotima, who teaches Socrates about the nature of Eros (desire). Eros, Diotima explains, is not a god but a Great Spirit — in-between mortal and immortal, ignorance and wisdom. Dr. Bannon traces Diotima's Ladder of Ascent from basic physical desire up to the direct apprehension of Beauty itself, and connects this to the course's broader theme of the 'whole soul.'

Diotima's Ladder of Ascent

Begin with love of a beautiful body. Recognize that beauty in other bodies is the same. Then fall in love with beauty of soul. Then with beauty of activities. Then with beauty of knowledge. Finally: glimpse Beauty Itself — the pure Form. Each rung of the ladder cultivates a less possessive, more universal desire.

Luke 15 — The Prodigal Son

The parable of the son who leaves home, squanders his inheritance, and returns — read through Diotima's lens, this is a story of metaxy: the son is 'lost' and 'found,' in-between his old self and the new. His return is a kind of metanoia.
