Rhetoric is often seen as a synonym for shallow, deceptive language, and therefore as something negative. But if we view rhetoric in more neutral terms, as the "art of persuasion", it is clear that we are all forced to engage with it at some level, if only because we are constantly exposed tothe rhetoric of others. In this Very Short Introduction, Richard Toye explores the purpose of rhetoric. Rather than presenting a defence of it, he considers it as the foundation-stone of civil society, and an essential part of any democratic process. Using wide-ranging examples from Ancient Greece, medieval Islamicpreaching, and modern cinema, Toye considers why we should all have an appreciation of the art of rhetoric.
