In Our Time

Melvyn Bragg and guests discuss the French philosopher Henri Bergson (1859-1941) and his ideas about human experience of time passing and how that differs from a scientific measurement of time, set out in his thesis on 'Time and Free Will' in 1889. He became famous in France and abroad for decades, rivalled only by Einstein and, in the years after the Dreyfus Affair, was the first ever Jewish member of the Académie Française. It's thought his work influenced Proust and Woolf, and the Cubists. He died in 1941 from a cold which, reputedly, he caught while queuing to register as a Jew, refusing the Vichy government's offer of exemption.WithKeith Ansell-Pearson Professor of Philosophy at the University of WarwickEmily Thomas Assistant Professor in Philosophy at Durham UniversityAnd Mark Sinclair Reader in Philosophy at the University of RoehamptonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the most destructive riots in London's history, which reached their peak on 7th June 1780 as troops fired on the crowd outside the Bank of England. The leader was Lord George Gordon, head of the Protestant Association, who objected to the relaxing of laws against Catholics. At first the protest outside Parliament was peaceful but, when Gordon's petition failed to persuade the Commons, rioting continued for days until the military started to shoot suspects in the street. It came as Britain was losing the war to hold on to colonies in North America.The image above shows a crowd setting fire to Newgate Prison and freeing prisoners by the authority of 'His Majesty, King Mob.'WithIan Haywood Professor of English at the University of RoehamptonCatriona Kennedy Senior Lecturer in Modern British and Irish History and Director of the Centre for Eighteenth Century Studies at the University of Yorkand Mark Knights Professor of History at the University of WarwickProducer: Simon Tillotson

Melvyn Bragg and guests discuss the life of Nero (37-68 AD) who became Emperor at the age of 16. At first he was largely praised for his generosity yet became known for his debauched lifestyle, with allegations he started the Fire of Rome, watching the flames as he played the lyre. Christians saw him as their persecutor, an anti-Christ, and the number of the Beast in the Book of Revelation was thought to indicate Nero. He had confidence in his own artistry, took up acting (which then had a very low status) and, as revolts in the empire grew, killed himself after the Senate condemned him to die as a slave, on a cross.

Melvyn Bragg and guests discuss one of Shakespeare's most popular works, written c1595 in the last years of Elizabeth I. It is a comedy of love and desire and their many complications as well as their simplicity, and a reflection on society's expectations and limits. It is also a quiet critique of Elizabeth and her vulnerability and on the politics of the time, and an exploration of the power of imagination.With Helen Hackett Professor of English Literature and Leverhulme Research Fellow at University College LondonTom Healy Professor of Renaissance Studies at the University of Sussexand Alison Findlay Professor of Renaissance Drama at Lancaster University and Chair of the British Shakespeare AssociationProducer: Simon Tillotson

Melvyn Bragg and guests discuss theories about the origins of teeth in vertebrates, and what we can learn from sharks in particular and their ancestors. Great white sharks can produce up to 100,000 teeth in their lifetimes. For humans, it is closer to a mere 50 and most of those have to last from childhood. Looking back half a billion years, though, the ancestors of sharks and humans had no teeth in their mouths at all, nor jaws. They were armoured fish, sucking in their food. The theory is that either their tooth-like scales began to appear in mouths as teeth, or some of their taste buds became harder. If we knew more about that, and why sharks can regenerate their teeth, then we might learn how humans could grow new teeth in later lives.

Melvyn Bragg and guests discuss why the potato crop failures in the 1840s had such a catastrophic impact in Ireland. It is estimated that one million people died from disease or starvation after the blight and another two million left the country within the decade. There had been famines before, but not on this scale. What was it about the laws, attitudes and responses that made this one so devastating?The image above is from The Illustrated London News, Dec. 29, 1849, showing a scalp or shelter, "a hole, surrounded by pools, and three sides of the scalp were dripping with water, which ran in small streams over the floor and out by the entrance. The poor inhabitants said they would be thankful if the landlord would leave them there, and the Almighty would spare their lives. Its principal tenant is Margaret Vaughan."With Cormac O'Grada Professor Emeritus in the School of Economics at University College DublinNiamh Gallagher University Lecturer in Modern British and Irish History at the University of Cambrid

Melvyn Bragg and guests discuss the effective partition of England in the 880s after a century of Viking raids, invasions and settlements. Alfred of Wessex, the surviving Anglo-Saxon king and Guthrum, a Danish ruler, had fought each other to a stalemate and came to terms, with Guthrum controlling the land to the east (once he had agreed to convert to Christianity). The key strategic advantage the invaders had was the Viking ships which were far superior and enabled them to raid from the sea and up rivers very rapidly. Their Great Army had arrived in the 870s, conquering the kingdom of Northumbria and occupying York. They defeated the king of Mercia and seized part of his land. They killed the Anglo-Saxon king of East Anglia and gained control of his territory. It was only when a smaller force failed to defeat Wessex that the Danelaw came into being, leaving a lasting impact on the people and customs of that area.With Judith Jesch Professor of Viking Studies at the University of NottinghamJohn Hines Prof

Melvyn Bragg and guests discuss the life and works of Hopkins (1844-89), a Jesuit priest who at times burned his poems and at others insisted they should not be published. His main themes are how he, nature and God relate to each other. His friend Robert Bridges preserved Hopkins' poetry and, once printed in 1918, works such as The Windhover, Pied Beauty and As Kingfishers Catch Fire were celebrated for their inventiveness and he was seen as a major poet, perhaps the greatest of the Victorian age.

Melvyn Bragg and guests discuss what it means to be oneself, a question explored by philosophers from Aristotle to the present day, including St Augustine, Kierkegaard, Heidegger and Sartre. In Hamlet, Polonius said 'To thine own self be true', but what is the self, and what does it mean to be true to it, and why should you be true? To Polonius, if you are true to yourself, ‘thou canst not be false to any man’ - but with the rise of the individual, authenticity became a goal in itself, regardless of how that affected others. Is authenticity about creating yourself throughout your life, or fulfilling the potential with which you were born, connecting with your inner child, or something else entirely? What are the risks to society if people value authenticity more than morality - that is, if the two are incompatible? The image above is of Sartre, aged 8 months, perhaps still connected to his inner child.With Sarah Richmond Associate Professor in Philosophy at University College LondonDenis McManus Professo

Melvyn Bragg and guests discuss the impact on the British Isles of William Cecil, 1st Baron Burghley, the most poweful man in the court of Elizabeth I. He was both praised and attacked for his flexibility, adapting to the reigns of Protestant and Catholic monarchs and, under Elizabeth, his goal was to make England strong, stable and secure from attack from its neighbours. He sought control over Ireland and persuaded Elizabeth that Mary Queen of Scots must die, yet often counselled peace rather than war in the interests of prosperity.

Melvyn Bragg and guests discuss the life, works, context and legacy of Antarah (525-608AD), the great poet and warrior. According to legend, he was born a slave; his mother was an Ethiopian slave, his father an elite Arab cavalryman. Antarah won his freedom in battle and loved a woman called Abla who refused him, and they were later celebrated in the saga of Antar and Abla. One of Antarah's poems was so esteemed in pre-Islamic Arabia that it is believed it was hung up on the wall of the Kaaba in Mecca.

Melvyn Bragg and guests discuss how members of the same species send each other invisible chemical signals to influence the way they behave. Pheromones are used by species across the animal kingdom in a variety of ways, such as laying trails to be followed, to raise the alarm, to scatter from predators, to signal dominance and to enhance attractiveness and, in honey bees, even direct development into queen or worker. The image above is of male and female ladybirds that have clustered together in response to pheromones.

Melvyn Bragg and guests discuss how artists from the Middle Ages onwards have been inspired by the Bible story of the widow who killed an Assyrian general who was besieging her village, and so saved her people from his army and from his master Nebuchadnezzar. A symbol of a woman's power and the defiance of political tyranny, the image of Judith has been sculpted by Donatello, painted on the ceiling of the Sistine Chapel and, in the case of Caravaggio, Liss and Artemisia Gentileschi, been shown with vivid, disturbing detail. What do these interpretations reveal of the attitudes to power and women in their time, and of the artists' own experiences? The image of Judith, above is from a tapestry in the Duomo, Milan, by Giovanni or Nicola Carcher, 1555With Susan Foister Curator of Early Netherlandish, German and British Painting at the National GalleryJohn Gash Senior Lecturer in History of Art at the University of AberdeenAnd Ela Nutu Hall Research Associate at the Sheffield Institute for Interdisciplinary Bibl

Melvyn Bragg and guests discuss the remarkable achievement of Aristotle (384-322BC) in the realm of biological investigation, for which he has been called the originator of the scientific study of life. Known mainly as a philosopher and the tutor for Alexander the Great, who reportedly sent him animal specimens from his conquests, Aristotle examined a wide range of life forms while by the Sea of Marmara and then on the island of Lesbos. Some ideas, such as the the spontaneous generation of flies, did not survive later scrutiny, yet his influence was extraordinary and his work was unequalled until the early modern period.The image above is of the egg and embryo of a dogfish, one of the animals Aristotle described accurately as he recorded their development.WithArmand Leroi Professor of Evolutionary Development Biology at Imperial College LondonMyrto Hatzimichali Lecturer in Classics at the University of CambridgeAndSophia Connell Lecturer in Philosophy at Birkbeck, University of LondonProducer: Simon Tillots

Melvyn Bragg and guests discuss the life of the Welsh nobleman, also known as Owen Glendower, who began a revolt against Henry IV in 1400 which was at first very successful. Glyndwr (c1359-c1415) adopted the title Prince of Wales and established a parliament and his own foreign policy, until he was defeated by the future Henry V. Owain Glyndwr escaped and led guerilla attacks for several years but was never betrayed to the English, disappearing without trace.With Huw Pryce Professor of Welsh History at Bangor UniversityHelen Fulton Professor of Medieval Literature at the University of BristolChris Given-Wilson Emeritus Professor of Medieval History at the University of St AndrewsProducer: Simon Tillotson

Melvyn Bragg and guests discuss the ideas and life of one of the greatest mathematicians of the 20th century, Emmy Noether. Noether’s Theorem is regarded as one of the most important mathematical theorems, influencing the evolution of modern physics. Born in 1882 in Bavaria, Noether studied mathematics at a time when women were generally denied the chance to pursue academic careers and, to get round objections, she spent four years lecturing under a male colleague’s name. In the 1930s she faced further objections to her teaching, as she was Jewish, and she left for the USA when the Nazis came to power. Her innovative ideas were to become widely recognised and she is now considered to be one of the founders of modern algebra.With Colva Roney Dougal Professor of Pure Mathematics at the University of St AndrewsDavid Berman Professor in Theoretical Physics at Queen Mary, University of LondonElizabeth Mansfield Professor of Mathematics at the University of Kent Producer: Simon Tillotson

Melvyn Bragg and guests discuss Samuel Beckett (1906 - 1989), who lived in Paris and wrote his plays and novels in French, not because his French was better than his English, but because it was worse. In works such as Waiting for Godot, Endgame, Molloy and Malone Dies, he wanted to show the limitations of language, what words could not do, together with the absurdity and humour of the human condition. In part he was reacting to the verbal omnipotence of James Joyce, with whom he’d worked in Paris, and in part to his experience in the French Resistance during World War 2, when he used code, writing not to reveal meaning but to conceal it.WithSteven Connor Professor of English at the University of CambridgeLaura Salisbury Professor of Modern Literature at the University of ExeterAnd Mark Nixon Associate Professor in Modern Literature at the University of Reading and co-director of the Beckett International FoundationProducer: Simon Tillotson

Melvyn Bragg and guests discuss why, in 1870, the Vatican Council issued the decree ‘pastor aeternus’ which, among other areas, affirmed papal infallibility. It meant effectively that the Pope could not err in his teachings, an assertion with its roots in the early Church when the bishop of Rome advanced to being the first among equals, then overall head of the Christian Church in the West. The idea that the Pope could not err had been a double-edged sword from the Middle Ages, though; while it apparently conveyed great power, it also meant a Pope was constrained by whatever a predecessor had said. If a later Pope were to contradict an earlier Pope, then one of them must be wrong, and how could that be…if both were infallible?WithTom O’Loughlin Professor of Historical Theology at the University of NottinghamRebecca Rist Professor in Medieval History at the University of ReadingAnd Miles Pattenden Departmental Lecturer in Early Modern History at the University of OxfordProducer: Simon Tillotson and Julia Jo

Melvyn Bragg and guests discuss the planet Venus which is both the morning star and the evening star, rotates backwards at walking speed and has a day which is longer than its year. It has long been called Earth’s twin, yet the differences are more striking than the similarities. Once imagined covered with steaming jungles and oceans, we now know the surface of Venus is 450 degrees celsius, and the pressure there is 90 times greater than on Earth, enough to crush an astronaut. The more we learn of it, though, the more we learn of our own planet, such as whether Earth could become more like Venus in some ways, over time.

Melvyn Bragg and guests discuss how, from 1834, poor people across England and Wales faced new obstacles when they could no longer feed or clothe themselves, or find shelter. Parliament, in line with the ideas of Jeremy Bentham and Thomas Malthus, feared hand-outs had become so attractive, they stopped people working to support themselves, and encouraged families to have more children than they could afford. To correct this, under the New Poor Laws it became harder to get any relief outside a workhouse, where families would be separated, husbands from wives, parents from children, sisters from brothers. Many found this regime inhumane, while others protested it was too lenient, and it lasted until the twentieth century.The image above was published in 1897 as New Year's Day in the Workhouse.WithEmma Griffin Professor of Modern British History at the University of East AngliaSamantha Shave Lecturer in Social Policy at the University of LincolnAnd Steven King Professor of Economic and Social History at the Uni
