The boy plays the cithara and sings to the enjoyment of all. Charmides remarks that, like wine, music blended with the beauty of youth has a pleasing effect. Socrates points out that the performers give the onlookers pleasure and suggests that the symposiasts should make an effort to please each other as well. Everyone asks what he means (3.2). Socrates replies that he wants Kallias to fulfill his promise and demonstrate his wisdom (sophia). Kallias says he will do so if everyone else will share what good thing he understands.

Antisthenes states that it certainly is, because gentlemanliness is never associated with injustice (3.4).
