In the Symposium, Plato presents one of philosophy's most beautiful accounts of love and beauty. Love (eros) is not merely desire or sentiment—it is a ladder leading from physical attraction to the highest knowledge: the vision of Beauty Itself.
Diotima's Teaching
Socrates recounts the teaching of Diotima, a priestess who instructed him about love. She reveals the true nature of eros and its connection to philosophy:
The Ladder of Love (Scala Amoris)
Love naturally ascends through stages, each higher than the last:
Rung 1: One Beautiful Body
First, we love one beautiful person. We desire physical union. This is where most people remain.
Rung 2: All Beautiful Bodies
We realize: beauty in one body resembles beauty in others. We love all beautiful bodies, not just one. Physical love becomes less exclusive.
Rung 3: Beautiful Souls
We recognize that beauty of soul surpasses beauty of body. We love virtue, wisdom, courage more than physical appearance.
Rung 4: Beautiful Institutions and Laws
We see beauty in well-ordered societies, just laws, noble customs. We love the political and social expressions of wisdom.
Rung 5: Beautiful Knowledge
We love knowledge itself—mathematics, science, philosophy. We desire understanding more than any physical or social good.
Rung 6: Beauty Itself
Finally, we contemplate the Form of Beauty—eternal, perfect, unchanging. We see beauty no longer in particular beautiful things, but Beauty as such.
"Whoever has been taught this far in the ways of Love, viewing beautiful things in the right order and manner, will suddenly have revealed to him, as he approaches Love's goal, a wondrous vision—Beauty's very self."
—Plato, Symposium 210e-211a
What is Eros?
Diotima teaches that eros is neither a god nor a mortal, but a daimon—a spirit intermediate between divine and human. Eros is the child of Resource and Poverty, forever seeking what he lacks.
Love is desire for beauty. But why? Because beauty promises happiness. We want to possess the beautiful forever. This is why love aims at immortality—through procreation (physical), through fame (social), or through philosophy (intellectual).
Love and Philosophy
The Greek word philosophia means "love of wisdom." Philosophy is literally a form of eros—desire for Beauty, Truth, Goodness. The philosopher is the lover, the Forms are the beloved.
This is why philosophy is so intense, so all-consuming. It's not mere curiosity—it's passion, longing, the soul's deepest yearning.
Plato vs. Romantic Love
Plato's view differs sharply from modern romanticism:
- Not about the individual: We don't love a person for their uniqueness. We love them as an instance of Beauty.
- Not ultimate: Romantic love is a step on a ladder, not the highest love.
- Not possession: Love aims at contemplation and creation, not ownership.
- Not primarily sexual: Physical desire is the lowest rung—philosophy is higher eros.
- Not mutual: The lover ascends toward Beauty; Beauty doesn't "love back."
Platonic Love
Our phrase "Platonic love" (non-sexual love) is somewhat a distortion. For Plato, all love begins with physical attraction—that's the first rung. But true lovers ascend beyond physical desire to intellectual and spiritual union.
"Platonic relationships" in Plato's Academy involved pederasty (older man/younger boy)—mentorship with erotic dimension, though ideally chaste. The older lover helps the younger ascend the ladder.
The Form of Beauty
What is Beauty Itself?
- Eternal: Not born, doesn't perish, unchanging
- Absolute: Not beautiful in one respect and ugly in another
- Not relative: Not more beautiful to some, less to others
- Not bodily: Not located in space
- Not dependent: Exists independently of beautiful things
- Simple: Not a compound of parts
Seeing Beauty Itself is the highest happiness. It makes life worth living. Everything else—fame, wealth, power—is worthless by comparison.
Modern Relevance
Plato's Symposium remains influential:
- The idea of love as ascent shapes spiritual traditions (Christian mysticism, Sufism)
- The connection between love and creativity resonates (artists driven by eros)
- The notion that beauty reveals truth influences aesthetics
- The danger of reducing love to physical desire is widely recognized
Whether or not we accept Plato's metaphysics, his insight that love can elevate and transform remains powerful.
