# Adeimantus — Dialogues character guide

> Adeimantus in Dialogues by Plato.

**Role:** supporting

**First appearance:** 0057-book-i

## Snapshot

Glaucon's brother, quieter but no less insistent, who presses Socrates to show why the just life is worth living even when no one is watching.

## Who they are

Adeimantus joins Glaucon in demanding that Socrates defend justice without appealing to the rewards of reputation that parents and poets dangle before the young. He is the more patient of the two brothers, but his challenge cuts deeper: if justice is praised only for its consequences, what reason remains to be just when no one sees? His question shapes the Republic's turn toward the soul's own order as the answer.
