Andrew Marr was in Paris on Friday to record a special edition of Start the Week about France. Hours later the Paris attacks happened. This programme is not about these attacks or Islamic State or the French role in the war in Syria, but it is a conversation about the political, cultural and religious fault lines in France from the 19th century to today. As BBC Radio 4 plans to broadcast a retelling of Emile Zola's 20 novel cycle, Les Rougon-Macquart, the journalist Anne-Elisabeth Moutet explores whether Zola is a 19th century gateway into understanding modern France. The novelist Agnès Desarthe has set her latest novel at the beginning of the 20th century and mixes the intimate with the great events of French history. The French Resistance is one of France's heroic myths and is central to the country's identity, but the historian Robert Gildea says the reality is far more complex. And contemporary France in all its complexity is represented in Karim Miské's thriller set among the radical Islamic preachers, Christian fundamentalists and corrupt police officers in one of the poorest suburbs of Paris.

Anne McElvoy presents a special edition of Start the Week at the Free Thinking Festival at Sage, Gateshead, exploring injustice, myth and the role of the poet 'to name the unnameable, to point at frauds, to take sides'. The American poet Claudia Rankine exposes the ever-present racial tensions in contemporary society, while the Syrian poet Amir Darwish, having arrived in the UK hanging underneath a lorry on a cross-channel ferry, writes of love, loss, exile and demonisation. The historian Catherine Fletcher looks at the stories told about Alessandro de'Medici, the 16th century duke of Florence who was believed to be mixed-race, and what those stories tell us about attitudes to race, while the philosopher Jules Holroyd tackles the thorny issue of implicit and unconscious bias.

On Start the Week Tom Sutcliffe discusses the importance of uncertainty and failure. The former head of the European Research Council Helga Nowotny argues research is fed by uncertainty and that any form of scientific inquiry may produce results that are ambiguous. She criticises policy makers for focusing on easy short-term solutions, but the former conservative MP and Minister for Universities and Science, David Willetts, understands the difficulty for governments in dealing with uncertainty. In his role at the think tank Resolution Foundation he's attempting to use analytical research to improve policy on living standards. Matthew Syed examines how a positive attitude to failure can lead to success in areas as diverse as sport, business, politics and healthcare. The failure of governments to come to an agreement on climate change will be discussed next month at a UN conference in Paris and Oliver Morton looks at whether the radical, yet uncertain, strategies of geo-engineering are the answer.

On Start the Week Andrew Marr talks to the playwright Ben Power whose latest work interweaves three of DH Lawrence's dramas to evoke a lost world of manual labour and working class pride. The sociologist Mike Savage proposes a new way to think about class in Britain which not only looks at economic and social issues, but cultural preferences. Meanwhile the American writer Siri Hustvedt questions the cultural misogyny at play in the world of art, and Peter Davies celebrates the artists inspired by the northern industrial landscape. Producer: Katy Hickman.
