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. Producer: Katy Hickman.

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. Producer: Katy Hickman.

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. Producer: Katy Hickman.

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.

On Start the Week the classicist Mary Beard tells Tom Sutcliffe that Ancient Rome matters: its debates about citizenship, security and the rights of the individual still influence our own debates on civil liberty. The Magna Carta is the starting point for the playwright Timberlake Wertenbaker's latest play which draws parallels between the King's abuse of power in 1215 and the global business elite today. The film director Stephen Frears tells the story of the meteoric rise and fall of one of the most celebrated and controversial sportsmen in recent history, Lance Armstrong, and of the journalist who was vilified when he tried to expose him. Lurid headlines take centre stage in the play Clarion, directed by Mehmet Ergen, which takes a satirical look at nationalism and the state of the British media. Producer: Katy Hickman.

On Start the Week Andrew Marr talks to historian Niall Ferguson about his biography of Henry Kissinger. Reviled and revered in equal measure Kissinger was the statesman at the heart of American foreign policy for decades, and Ferguson argues that far from being a Machiavellian realist he was driven by idealism. Jane Smiley's trilogy of novels chart a hundred years of American life through the lives of one family. She shows clearly how the big political and social upheavals of the time were reflected in the day-to-day. The personal and political come together in the extraordinary diaries of Ivan Maisky, the Russian ambassador to London before WWII. Gabriel Gorodetsky has compiled the diaries which document Britain's drift to war during the 1930s. Producer: Katy Hickman.

On Start the Week Tom Sutcliffe talks to the American writer Jonathan Franzen about his latest novel, Purity. One of Franzen's characters compares the internet with the East German Republic and he satirises the utopian ideas of the apparatchik web-users. The head of the Oxford Internet Institute Helen Margetts counters with her research on the success and failure of political action via social media. The artist Tacita Dean laments the ubiquity of digital at the expense of film, and the financial journalist Gillian Tett roots out tunnel vision - both personal and business - in her new book on silos. Producer: Katy Hickman.

On Start the Week Mary Ann Sieghart explores how far leaders and governments have shaped our world. Matt Ridley dismisses the assumption that history has been made by those on high, whether in government, business or religion, and argues for a system of evolution in which ideas and events develop from the bottom up. The historian Tom Holland revels in the antics of the house of Caesar, from Augustus to Nero, and how this imperial family greatly influenced the ancient world. Barry Cunliffe tells the story of the beginnings of civilisation across Europe and the Far East over the course of ten millennia while the curator Julia Farley concentrates on one of those groups - the Celts - and celebrates their distinctive stylised art in a new exhibition at the British Museum. Producer: Katy Hickman.

Start the Week returns for a new series with a discussion about cultural exchange. Andrew Marr talks to the potter Edmund de Waal about his fascination with porcelain. De Waal's journey to understand the history and secrets of 'white gold' takes him from China to Europe and the USA. From white pots to multi-coloured: the contemporary Chinese artist Ai Weiwei mounts an exhibition at the Royal Academy; co-curator Tim Marlow explores his cultural significance. The poet Annie Freud takes inspiration from shards of pottery found in her garden for her collection, The Remains. Producer: Katy Hickman.

Mary Ann Sieghart discusses harmony and balance, in the universe and on a smaller scale. She is joined by Nobel Prize winning physicist Frank Wilczek, whose new book examines whether beauty is one of the organising principles of the universe, and by the choreographer Shobana Jeyasingh, who uses dance to explore our relationship with science and technology. The mathematician and standup comedian Matt Parker outlines things you can make and do in the fourth dimension, and the Canadian baritone opera singer and keen amateur astronomer Gerald Finley brings his perspective to bear. Producer: Katy Hickman.
