The Measures Taken and Other Lehrstucke: Methuen Drama Modern Plays

The Lehrstücke (or 'learning-plays') lie at the heart of Brechtian theatre.
>The Lehrstücke are spare and highly formalized pieces intended for performance by amateurs, on the principle that the moral and political lessons contained in them can best be taught by participation in an actual production. There is nothing in the drama of the twentieth century to match the precision of their language and the economy of their theatrical technique.
