The opening of "Protagoras" sets the stage as Socrates recounts a visit from Hippocrates, who is eager to study under Protagoras, believing him to be the key to political wisdom. Socrates, however, urges caution and reflection on the dangers of committing oneself to a Sophist without fully understanding their teachings. When they arrive at the house of Callias where Protagoras is staying, they engage in a rich discussion about what Protagoras claims to teach: the art of being a good citizen and achieving personal and communal betterment. The dialogue reveals the tension between Socratic inquiry—which often challenges the certainty of definitions and claims made by Sophists—and Protagoras’ assertions regarding the teachability of virtue, setting the groundwork for a deeper exploration of moral philosophy.
