Aristotle wrote a work on rhetoric that would define a discipline. He rejected Plato's denunciation of rhetoric and showed why it is an art, a discipline, or a science and gathered the gems of all the manuals of rhetoric up to his day in a work that has endured for over 2000 years. Richard Enos and David Isaksen discuss some of its main contributions to rhetorical studies and what you can learn from it to give a good speech and lead ethically by persuasion.
