This week Neil MacGregor's history of the world is examining the forces that helped shape our way of life and ways of thinking today. He began with the political revolution that exploded In Russia in the 1920s and today he moves on to the sexual revolution of the 1960s. He explores the emergence of legally enshrined human rights and the status of sexuality around the world. He tells the story with the aid of a David Hockney print, one of a series that was made in 1966 as the decriminalisation of homosexuality was being planned, at least in Britain. We hear from David Hockney on the spirit of the decade and from Shami Chakrabarti, the director of the human rights group Liberty
