A Tui is an intellectual who sells his or her abilities and opinions as a commodity in the marketplace or who uses them to support the dominant ideology of an oppressive society. The German modernist theatre practitioner Bertolt Brecht invented the term and used it in a range of critical and creative projects, including the material that he developed in the mid-1930s for his so-called Tui-Novel—an unfinished satire on intellectuals in the German Empire and Weimar Republic—and his epic comedy from the early 1950s, Turandot or the Whitewashers' Congress.
