Book excerpt: Democracy, argues David Wiles, is actually a form of theatre. In making his case, the author deftly investigates orators at the foundational moments of ancient and modern democracy, demonstrating how their performative skills were used to try to create a better world. People often complain about demagogues, or wish that politicians might be more sincere. But to do good, politicians (paradoxically) must be hypocrites - or actors. Moving from Athens to Indian independence via three great revolutions – in Puritan England, republican France and liberal America – the book opens up larger questions about the nature of democracy. When in the classical past Plato condemned rhetoric, the only alternative he could offer was authoritarianism. Wiles' bold historical study has profound implications for our present: calls for personal authenticity, he suggests, are not an effective way to counter the rise of populism.
