Gorgias

We’ve spent a lot of time in the dialogues talking to and about Sophists, but Socrates has an awfully hard time figuring out exactly what a Sophist is and what they teach. In Protagoras, Socrates' friend Hippocrates wants to take lessons from Protagoras, but when questioned can’t quite explain what he expects to learn, and Protagoras doesn’t really give a straight answer. In Greater Hippias, we’re able to gather from the greatest Sophist of them all (in his own estimation) that they are primarily concerned with public speaking.
