I will never tire of repeating, let young people learn by doing, not by what you say.But let him not learn from books what he can learn from experience.When they don't want to convince anyone at all, have nothing to convince others, and sit at the desk with nothing to say, you force them to feel, to feel the charm of passionate language, the power of persuasive art, and let them practice Eloquence, how absurd!If I were to teach rhetoric to a teenager whose lust and passion were not yet fully developed, I would keep his attention drawn to the things that arouse his desire, and then I would discuss with him how he would Speech to persuade others, so that others are willing to help him get these things.
