"Cancel culture" is used to describe debates which touch on freedom of expression today but what can we learn if we look back at events after the 1789 Declaration of the Rights of Man and Citizen? Clare Siviter, who lectures on the French Revolution and theatre at the University of Bristol, takes us through the experiences of playwrights and authors, Marie-Joseph Chénier, Olympe de Gouges, Jean-Baptiste-Antoine Suard and Destutt de Tracy, who wrote about how ideas spread. Producer: Torquil MacLeod You can find a collection of essays, discussions and features which showcase the research of New Generation Thinkers on the Free Thinking programme website.
