In this last section of the dialogue, we see Euthyphro choosing to walk away rather than propose another definition of the holy (to hosion). Socrates still praises Euthyphro for his wisdom, but in such a way that anyone with thicker skin than Euthyphro would rethink his prosecution of his father. Socrates claims to want to know what the holy is not only to prevent his own case from coming to court, but more generally in order to live better. This provides us with the clue we needed to explain why Socrates is bothering to talk with Euthyphro, to help Euthyphro live a better life.

Here I read through Platonic dialogues, translating and commenting on the Greek text as I go.
