The Charmides (Ancient Greek: Χαρμioηc) is a dialogue of Plato, in which Socrates engages a handsome and popular boy in a conversation about the meaning of sophrosyne, a Greek word usually translated into English as "temperance", "self-control", or "restraint". As is typical with Platonic dialogues, the two never arrive at a completely satisfactory definition, but the discussion nevertheless raises many important points.
