About this book
What if winning every argument means losing sight of the truth?
At the Lyceum in Athens, two visiting brothers promise to teach virtue faster than anyone alive. Euthydemus and Dionysodorus turn their attention to young Cleinias, using slippery words and clever traps to put on a show. Socrates tells his friend Crito about this strange afternoon, where a question about learning becomes a contest over meaning.
In Plato's funny, sharp dialogue, Socrates offers another way to think. He speaks gently with Cleinias, asking what wisdom gives us and how knowledge helps us use good things well. Beside the brothers' verbal tricks, his honest questions make the stakes clear: does education teach us to defeat others, or to seek what is true?

Two brothers promise to teach virtue
The book opens with a short frame. Crito meets Socrates and asks who the man was that Socrates was talking with the day before. Socrates answers by retelling the whole episode from memory. He had been sitting alone in the changing room of the Lyceum when two newcomers walked in with a crowd of followers.
These are the brothers Euthydemus and Dionysodorus, originally from Chios. They had lived in Thurii, a colony in southern Italy, before being driven out and wandering Greece. Socrates says they were once expert fighters in heavy armor and then became masters of arguing in law courts. Now they have found a third skill, which is arguing in any way at all, and refuting any claim whatever, true or false.

What is Plato's Euthydemus about?
It tells how Socrates meets two sophist brothers, Euthydemus and Dionysodorus, who claim to teach virtue through clever arguments. Socrates contrasts their word tricks with honest questioning and shows that wisdom is the one true good.
Who are Euthydemus and Dionysodorus?
They are two brothers from Chios who travelled Greece as teachers. They had once taught fighting in armor and law court speaking. In the dialogue they teach eristic, the art of winning arguments by refuting any claim.
What is eristic in Plato?
Eristic is argument aimed only at winning, whatever the truth. Plato sets it against dialectic, the cooperative search for truth. The brothers use eristic, while Socrates shows the other way.
