In The Theory of the Modern Stage, leading drama critic, Eric Bentley, brings together landmark writings by dramatists, directors and thinkers who have had a profound effect on the theatre since the mid nineteenth century, from Adolphe Appia to Émile Zola. Here, Antonin Artaud sets out a manifesto for a Theatre of Cruelty, Bertolt Brecht discusses the tension between entertainment and instruction in experimental drama and Bernard Shaw defends himself as a realist, while W. B. Yeats describes the creation of a People's Theatre. The ideas of theatre's great makers are revealed by their best expositors, as Eric Bentley writes about Stanislavsky belief in the importance of emotional memory when creating a dramatic role and Arthur Symons considers Richard Wagner and the relationship between genius, art and nature.
