Euthyphro

Euthyphro is a philosophical dialogue by Plato, part of the Socratic dialogues. It is set in the days before Socrates’ trial, and follows a conversation between Socrates and Euthyphro about piety and its relation to justice. Instead of a conventional plot, the book moves through careful questioning and definitions, using a short exchange to test how far a moral idea can be pinned down without slipping into contradiction.

This is a good fit for readers interested in ancient philosophy, especially questions about religion, ethics, and how we define abstract ideas. It also suits anyone looking for a compact entry point into Plato, since the focus is on argument and method rather than story. The tone is direct and probing, and the form connects naturally with other Socratic dialogues and with works that turn conversation into a philosophical investigation.
