Synopsis
Socrates discusses with a friend who, in contrast with other Platonic dialogues, is ''not'' the Hipparchus of title, and remains unnamed throughout the text. The dialogue opens with a direct question by which Socrates sets the theme for the entire discussion, namely "what is love of gain" (''τί γὰρ τὸ φιλοκερδές''). His friend answers that it's considering it "worth while to make gain out of things of no worth" (225a), which Socrates proves impossible, as all men who make gains have knowledge of their vocation, and know worthy from worthless in their particular domain (225b-226d). Socrates continues by asserting that gain is good and loss is evil, to which his friend agrees (227a), and then moves to show that since all men want what is good, necessarily, all men must love gain (227c).
Socrates's friend suggests the two of them need to redefine their term if the argument is going to progress, and suggests that a "love of gains" is one who "thinks fit to make gain from, things from which honest men do not dare" (227d). All gain is good, he says, but some gain incurs a "net loss" when it harms the gainer (227e). Socrates reminds his friend they agreed that gain is good, so it can do no harm, and suggests that he is being dishonest with him. The discussion then digresses into a story (228b-229d) about

, who became known for his sayings, one of which apparently was "never deceive a friend", which is why Socrates mentions the story as a complaint. The story mentions a curious version of Hipparchus's death, as killed by two other Athenians over the admiration of a young boy.
The dialogue concludes with Socrates proving to his friend, who agrees unwillingly, that all gain is good.
