Is Justice First and Public Speaking Second?

Polis says Gorgias would actually teach people justice if they didn't already know it. So he's also implying that, hey, you're insulting most people because you're saying that most people don't know what justice is and they need to be instructed. All right, now, all of that, I mean, pretty good response from Polis given what he's been taught. It leads to this question, which is whether people like Gorgias should consider justice first and public speaking and power second. And if they did so, if they put their mind to justice and became convinced as to what justice is,. that they might not even feel right about practicing rhetoric the way they do
