> Simmias in Dialogues by Plato.

**Role:** supporting

**Also known as:** Simmias the Theban, the Theban

**First appearance:** 0047-phaedo

## Snapshot

A Theban philosopher who joins Socrates in the Phaedo to test whether the soul can survive death, pressing hard on the arguments he hears.

## Who they are

Simmias arrives at Socrates' cell with his friend Cebes, bringing Pythagorean interests and a willingness to argue rather than merely mourn. He offers the image of the soul as a harmony of the body, then worries that this analogy may not support immortality, showing a mind that would rather follow the argument than accept comfort. He matters because his objections force Socrates to refine the case for the soul's survival, turning the last hours into a genuine philosophical inquiry rather than a farewell.
