Aristotle was a Greek philosopher in the 4th century BCE who studied and wrote on many diverse subjects including logic, philosophy, ethics, physics, biology, politics, and rhetoric. Rhetoric is the art of persuasion through appealing to an audience's logic, ethics, and emotions. When trying to persuade, a speaker or writer can employ logos by making a logical argument based on facts and evidence, ethos by establishing their credibility and character as trustworthy, and pathos by appealing to the audience's emotions. Examples are provided that demonstrate the effective use of logos, ethos, and pathos in writing and speeches.
