Church Historian Diarmaid Macculloch joins Anne McElvoy to discuss the role that silence has played in the development of Christianity. David Dewing, director of The Geffrye Museum, argues that the museum sector neglects a focus on the middle classes; historian Selina Todd joins him to debate this idea. Actor Edward Petheridge and gerontologist Raymond Tallis discuss the neurological impact of the two strokes Petheridge suffered whilst rehearsing for the role of King Lear, which is the subject of a new play My Perfect Mind. And film critic Ian Christie remembers the novelist and screenwriter Ruth Prawer Jhabvala.
