In Our Time

Melvyn Bragg and guests discuss the poetry, the tragedy and the idealism of the Later Romantics. There must have been something extraordinary about the early 19th century, when six of the greatest poets in the English language were all writing. William Blake was there and Wordsworth and Coleridge had established themselves as the main players in British poetry, when the youthful trio of Byron, Shelley and Keats erupted – if not straight onto the public stage, then at least onto the literary scene. The great chronicler of the age was William Hazlitt, whose romantic maxim was: “Happy are they who live in the dream of their own existence and see all things in the light of their own minds; who walk by faith and hope; to whom the guiding star of their youth still shines from afar and into whom the spirit of the world has not yet entered…the world has no hand on them.” How fitting an epitaph is that for the three great poets who all died tragically young? What were the ideals that drove them and how did their unconventional lifestyles infect the poetry they left behind?With Jonathan Bate, Professor of English Literature at the University of Warwick; Robert Woof, Director of the Wordsworth Trust; Jennifer Wallace, Director of Studies in English at Peterhouse, Cambridge.

Melvyn Bragg and guests discuss the concept of original sin and its influence in Christian Europe. Genesis tells the Bible’s story of creation, but it also carries within it a tale of the ‘fall of mankind’. After their primal transgression, Adam and Eve are banished from Eden and cursed by God:“Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life.”What effect has this passage had on western culture, and how did the concept of an ‘original sin’ influence gender and morality in Christian Europe?With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Griselda Pollock, Professor of Art History at the University of Leeds; John Carey, Emeritus Professor of English Literature at Oxford University.

Melvyn Bragg and guests discuss the astonishing productivity of the Chinese Golden Age. 400 BC to 200 AD is known as the Axial Age, when great civilisations in Asia and the Mediterranean forged the ideas that dominated the next two thousand years. In China the equivalent to the Golden Age in Greece was the Warring States Period. It was a time of political turmoil, economic change and intellectual ferment that laid the foundations for the first Chinese Empire. Astronomy was systematised, the principles of Yin and Yang were invented, Confucianism grew and Taoism emerged, as a hundred schools of thought are reputed to have vied for the patronage of rival kings.Why was a period of war such a fertile age for culture and thought, what kinds of ideas were developed and how do they still inform the thinking of nearly a fifth of the world’s population?With Dr Chris Cullen, Director of the Needham Research Institute at Cambridge University; Dr Vivienne Lo, Lecturer at the Wellcome Trust Centre for the History of Medicine; Carol Michaelson, Assistant Keeper of Chinese Art in the Department of Oriental Antiquities at the British Museum.

Melvyn Bragg and guests discuss the 30 year search to solve all the biggest questions in physics. At the end of the last century, brave voices were predicting that all the big questions of physics were on the verge of being answered by a Theory of Everything. The disparity between the physics of the very small would finally be reconciled with the very large, and the four forces of nature would finally be united with a single set of equations. It was suggested that with such a theory we might solve the riddle of black holes, unlock the secrets of the Big Bang, probe other universes and even uncover the mystery of travelling through time. But Stephen Hawking, who once said that with a Theory of Everything “we would know the mind of God”, has changed his mind and now says that it may not be possible after all. So what are the prospects for a Theory of Everything? Why do we need one? How do we get one? And what would it mean if we did? With Brian Greene, Professor of Physics and Mathematics at Columbia University and author of The Fabric of the Cosmos; John Barrow, Professor of Mathematical Sciences at the University of Cambridge and author of The Constants of Nature; Dr Val Gibson, particle physicist from the Cavendish Laboratory and Fellow of Trinity College, Cambridge.

Melvyn Bragg and guests discuss the Vikings’ myths. Thor’s huge hammer, the wailing Valkyrie, howling wolves and fierce elemental giants give a rowdy impression of the Norse myths. But at the centre of their cosmos stands a gnarled old Ash tree, from which all distances are measured and under which Valhalla lies. In the first poem of The Poetic Edda, where the stories of the Norse Gods are laid down in verse, the Seeress describes it in her prophesy: “I know that an ash-tree stands called Yggdrasil,a high tree soaked with shining loamfrom there come the dews which fall in the valley, ever green, it stands over the well of fate.” It is from this tree that the father of the Gods, Odin, will ultimately hang himself: an image of divine sacrifice so problematic for thirteenth century Christians that they left it out when they wrote the myths down.What was the theology that inspired the Vikings and what role did their myths and religion play in their daily lives?With Carolyne Larrington, Tutor in Medieval English at St John’s College, Oxford; Heather O’Donoghue, Vigfusson Rausing Reader in Ancient Icelandic Literature in the Department of English at Oxford University; John Hines, Professor of Archaeology at Cardiff University.

Melvyn Bragg and guests discuss the interpretation of dreams. Over a hundred years ago, Sigmund Freud declared confidently, “The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind”. He was writing in his famous volume, The Interpretation of Dreams and his ideas made a huge impact on the century that was to follow. However, despite the cultural influence of his work, there is still no agreement in neuroscience as to the function or mechanism of dreaming; this is partly because for much of the century the prevailing wisdom was that there was no meaning to dreams at all.What is the mental circuitry that creates our dreams? If they have no meaning, why do we dream them? And why is the tide turning with neuroscientists starting to find reasons to take dreams seriously again?With Professor V S Ramachandran, Director of the Center for Brain and Cognition at the University of California, San Diego; Mark Solms, Professor of Neuropsychology at the University of Cape Town; Martin Conway, Professor of Psychology at the University of Durham.

Melvyn Bragg and guests discuss the Mughal Empire which, at its height, stretched from Bengal in the East to Gujarat in the West, and from Lahore in the North to Madras in the South.  It covered the whole of present day northern India, Pakistan, Afghanistan and Bangladesh, and became famous for the Taj Mahal, the Koh-i-Noor and the Peacock Throne.  In 1631 a Dutch naturalist Johannes de Laet published his account of the vast Empire, “the nobles live in indescribable luxury and extravagance, caring only to indulge themselves whilst they can, in every kind of pleasure.  Their greatest magnificence is in their women’s quarters, for they marry three or four wives or sometimes more”.But were they really the opulent despots of European imagination?  If so, how did they maintain such a vast territory?  And to what extent was the success of the British Raj a legacy of their rule? With Sanjay Subrahmanyam, Professor of Indian History and Culture at the University of Oxford; Susan Stronge, Curator in the Asian Department of the Victoria and Albert Museum, London; Chandrika Kaul, Lecturer in Imperial History at the University of St Andrews.

Melvyn Bragg and guests discuss Ernest Rutherford. He was the father of nuclear science, a great charismatic figure who mapped the landscape of the sub-atomic world. He identified the atom’s constituent parts, discovered that elemental decay was the cause of radiation and became the first true alchemist in the history of science when he forced platinum to change into gold. He was born at the edge of the Empire in 1871, the son of Scottish immigrant farmers and was working the fields when a telegram came from the great British physicist J J Thomson asking him to come to Cambridge. Rutherford immediately laid down his spade saying "that’s the last potato I ever dig". It was. He went on to found a science, win a Nobel Prize and pioneer the ‘big science’ of the twentieth century. With Simon Schaffer, Professor in the History and Philosophy of Science at the University of Cambridge; Jim Al–Khalili, Senior Lecturer in Physics at the University of Surrey; Patricia Fara, Fellow of Clare College, Cambridge.

Melvyn Bragg and guests discuss a transcendental idea that took hold on the Age of Enlightenment. When the English essayist John Hall translated the work of an obscure Roman thinker into English, he could hardly have known the ferment it would cause; for the work of Longinus introduced late 17th century Britain to the idea of the sublime – an idea that stalked the proceeding century. Longinus wrote, “As if instinctively, our soul is lifted up by the true sublime; it takes a proud flight, and is filled with joy and vaunting, as though it had itself produced what it had heard”.He was talking about the power of language, but in the 18th century the idea was set for a broader stage as British artists, poets, philosophers and scientists grappled with the sublime and adapted it to great swathes of the intellectual and physical landscape. What drove the great minds of the age to invest so much in the defining of the state of awe?With Janet Todd, Professor of English Literature at the University of Glasgow; Annie Janowitz, Professor of Romantic Poetry at Queen Mary, University of London; Peter de Bolla, Lecturer in English at the University of Cambridge.

Melvyn Bragg and guests discuss the Battle of Thermopylae. For the historian Herodotus, the Battle of Thermopylae was the defining clash between East and West: “The Persians fell in their scores, for the officers stood behind lashing them forward, forward all the time. Many fell into the sea and were drowned, many more were trampled to death by their comrades ... The Greeks knew they were doomed now the Persians had discovered a way round the hill, and put forth their last ounce of strength, utterly desperate, utterly unsparing of their lives. (King) Leonidas fell in this battle. He had proved himself a great and brave man”.A force of three hundred free Spartans and their King had stood and fallen before an invading army of three million, led by a brutal tyrant. Or so the story goes – such was their courage and its association with freedom that, nearly two and a half thousand years later, William Golding wrote, “A little of Leonidas lies in the fact that I can go where I like and write what I like. He contributed to setting us free”.How important are the Greek/Persian wars to the story of democracy? Was the West and its values really so far removed from life in the Persian Empire?With Tom Holland, historian and author of Persian Fire; Simon Goldhill, Professor in Greek Literature and Culture at King’s College, Cambridge; Edith Hall, Leverhulme Professor of Greek Cultural History at the University of Durham and author of Inventing the Barbarian: Greek Self-Definition through Tragedy.

Melvyn Bragg and guests discuss the origins and history of codes. In October 1586, in the forbidding hall of Fotheringhay Castle, Mary Queen of Scots was on trial for her life. Accused of treason and denied legal representation, she sat alone in the shadow of a vast and empty throne belonging to her absent cousin and arch rival Elizabeth I of England. Walsingham, Elizabeth’s Principal Secretary, had already arrested and executed Mary’s fellow conspirators, her only hope lay in the code she had used in all her letters concerning the plot. If her cipher remained unbroken she might yet be saved. Not for the first time the life of an individual and the course of history depended on the arcane art of Cryptography.What are the origins of this secretive science? And what links the ‘Caesar Cipher’ with the complex algorithms which underpin so much of our modern age?With Simon Singh, science writer and author of The Code Book: The Secret History of Codes and Code-Breaking; Professor Fred Piper, Director of the Information Security Group at Royal Holloway, University of London and co-author of Cryptography: A Very Short Introduction; Lisa Jardine, Professor of Renaissance Studies at Queen Mary, University of London and author of Ingenious Pursuits.

Melvyn Bragg discusses Jean-Baptiste Lamarck, the 18th century French scientist.Charles Darwin defined Natural Selection in On the Origin of Species, “Variations, however slight and from whatever cause proceeding, if they be in any degree profitable to the individuals of a species… will tend to the preservation of such individuals, and will generally be inherited by the offspring”. It was a simple idea that had instant recognition, “How extremely stupid not to have thought of that!” said T H Huxley. However, Darwin did not invent the idea of evolution and not everyone saw his ideas as original. The great geologist Charles Lyell repeatedly referred to “Lamarck’s theory as modified by Darwin”, Darwin complained to him, “I believe this way of putting the case is very injurious to its acceptance”. He desperately wanted to escape the shadow of this genuine scientific precursor and what has become known as the ‘Lamarckian Heresy’ has maintained a ghostly presence on the fringes of biology to this day.Who was Lamarck? How did Natural Selection escape from his shadow and gain acceptance from the scientific establishment? And has any evidence emerged that might challenge the elegant simplicity of Darwin’s big idea?With Sandy Knapp, Senior Botanist at the Natural History Museum, Steve Jones, Professor of Genetics in the Galton Laboratory at University College London and author of Almost Like a Whale: The Origin of Species Updated; Simon Conway Morris, Professor of Evolutionary Paleobiology at Cambridge University.

Melvyn Bragg and guests discuss the feat of astonishing intellectual engineering which provides us with millions of words in hundreds of languages. At the start of the twentieth century, in the depths of an ancient Egyptian turquoise mine on the Sinai peninsular, an archaeologist called Sir Flinders Petrie made an exciting discovery. Scratched onto rocks, pots and portable items, he found scribblings of a very unexpected but strangely familiar nature. He had expected to see the complex pictorial hieroglyphic script the Egyptian establishment had used for over 1000 years, but it seemed that at this very early period, 1700 BC, the mine workers and Semitic slaves had started using a new informal system of graffiti, one which was brilliantly simple, endlessly adaptable and perfectly portable: the Alphabet. This was probably the earliest example of an alphabetic script and it bears an uncanny resemblance to our own.Did the alphabet really spring into life almost fully formed? How did it manage to conquer three quarters of the globe? And despite its Cyrillic and Arabic variations and the myriad languages it has been used to write, why is there essentially only one alphabet anywhere in the world? With Eleanor Robson, historian of Ancient Iraq and Fellow of All Souls College, Oxford; Alan Millard, Rankin Professor Emeritus of Hebrew and Ancient Semitic Languages at the University of Liverpool; Rosalind Thomas, Professor of Greek History at Royal Holloway, University of London.

Melvyn Bragg and guests discuss the history of the Devil. In the Gospel according to John he is ‘a murderer from the beginning’, ‘a liar and the father of lies’, and Dante calls him ‘the ill Worm that pierces the world’s core’. But Milton’s description of him as a powerful rebel was so attractive that William Blake declared that Milton was ‘of the Devil’s party, without knowing it’. To ordinary folk the Devil has often been regarded as a trickster, a tempter, sometimes even a figure of fun rather than of fear. How did this contradictory character come into being? Why did it take so long for him to become an established figure in Christianity? And if the Devil did not exist, would we have had to invent him? With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Alison Rowlands, Senior Lecturer in European History at the University of Essex; David Wootton, Professor of Intellectual History at Queen Mary, University of London.

Melvyn Bragg and guests discuss the life, work and legacy of Ludwig Wittgenstein. There is little doubt that he was a towering figure of the twentieth century; on his return to Cambridge in 1929 Maynard Keynes wrote, “Well, God has arrived. I met him on the 5:15 train”.Wittgenstein is credited with being the greatest philosopher of the modern age, a thinker who left not one but two philosophies for his descendents to argue over: The early Wittgenstein said, “the limits of my mind mean the limits of my world”; the later Wittgenstein replied, “If God looked into our minds he would not have been able to see there whom we were speaking of”. Language was at the heart of both. Wittgenstein stated that his purpose was to finally free humanity from the pointless and neurotic philosophical questing that plagues us all. As he put it, “To show the fly the way out of the fly bottle”.How did he think language could solve all the problems of philosophy? How have his ideas influenced contemporary culture? And could his thought ever achieve the release for us that he hoped it would?With Ray Monk, Professor of Philosophy at the University of Southampton and author of Ludwig Wittgenstein: The Duty of Genius; Barry Smith, Lecturer in Philosophy at Birkbeck, University of London; Marie McGinn, Senior Lecturer in Philosophy at the University of York.

Melvyn Bragg and guests discuss the infamous St Bartholomew’s Day Massacre. In Paris, in the high summer of 1572, a very unusual wedding was happening in the cathedral of Notre Dame. Henri, the young Huguenot King of Navarre, was marrying the King of France’s beloved sister, Margot, a Catholic. Theirs was a union designed to bring together the rival factions of France and finally end the French Wars of Religion. Paris was bustling with Huguenots and Catholics and, though the atmosphere was tense, the wedding went off without a hitch. And as they danced together at the Louvre, it seemed that the flower of French nobility had finally come together to bury its differences.That wasn’t to be: on St Bartholomew’s Day, four days after the ill-starred nuptials, so many Protestants were killed in the streets of Paris that the River Seine ran red with their blood. Was the wedding a trap? Who was to blame for the carnage and what impact did it have on the Reformation in Europe?With Diarmaid MacCulloch, Professor of the History of the Church at Oxford University and author of a new book: Reformation: Europe’s House Divided 1490-1700; Mark Greengrass, Professor of History at the University of Sheffield; Penny Roberts, Lecturer in History at the University of Warwick.

Melvyn Bragg and guests discuss the age of the Earth. It was once thought that the world began in 4004 BC. Lord Kelvin calculated the cooling temperature of a rock the size of our planet and came up with a figure of 20 million years for the age of the Earth. Now, the history of our planet is divided into four great Eons: the Hadean, the Archaen, the Proterozoic and the Phanerozoic. Together, they are taken to encompass an incredible four and a half billion years. How can we begin to make sense of such a huge swathe of time? And can we be sure that we have got the Earth's age right? Geologists use Eras, Periods and Epochs to further punctuate what's known as 'Deep Time', but can we be sure that the classifications we use don't obscure more than they reveal? With Richard Corfield, Research Associate in the Department of Earth Sciences at Oxford University; Hazel Rymer, Senior Lecturer in the Department of Earth Sciences at the Open University; Henry Gee, Senior Editor at Nature.

Melvyn Bragg and guests discuss the concept of duty. George Bernard Shaw wrote in his play Caesar and Cleopatra, “When a stupid man is doing something he is ashamed of, he always declares that it is his duty”. But for Horatio Nelson and so many others, duty has provided a purpose for life, and a reason to die – “Thank God I have done my duty” were his final words.The idea that others have a claim over our actions has been at the heart of the history of civilised society, but duty is an unfashionable or difficult notion now - perhaps because it seems to impose an outside authority over self interest. The idea of duty has duped people into doing terrible things and inspired them to wonderful achievements, and it is an idea that has excited philosophers from the time people first came together to live in large groups. But has duty always meant doing what’s best for others rather than oneself? And how did it become such a powerful idea that people readily gave their lives for it? With Angie Hobbs, Lecturer in Philosophy at the University of Warwick; Annabel Brett, Fellow of Gonville and Caius and Lecturer in History at the University of Cambridge; Anthony Grayling, Reader in Philosophy at Birkbeck, University of London.

Melvyn Bragg and guests discuss sensation, a Victorian literary phenomenon. The Archbishop of York fulminated against them in his sermons, they spread panic through the pages of The Times and in a famous review the Oxford Professor of Philosophy, Henry Mansel, called them “unspeakably disgusting” with a “ravenous appetite for carrion”: in the 1860s the novels of Sensation took the Victorian world by storm.Bigamy. Secrecy. Murder and Madness. Detectives and surprise plot twists - all in a genteel domestic setting. It was a compelling concoction that propelled sales of the genre into millions, and for the first time ever got those above stairs reading the same stories as their servants.How did Sensation achieve such an incredible popularity so fast? What did the ensuing moral panic reveal about the society in which the novels were set? And in terms of its literary reputation, does this racy genre deserve to languish so far behind Victorian Realism, its rather steadier cousin?With John Mullan, Senior Lecturer in English at University College London; Lyn Pykett, Professor of English and Pro-Vice Chancellor at the University of Wales, Aberystwyth; Dinah Birch, Professor of English at the University of Liverpool.

Melvyn Bragg and guests discuss the centuries old myth of the most romantic noble outlaw. The first printed version of the Robin Hood story begins like this:“Lithe and Lysten, gentylmen/That be of frebore blodeI shall tell of a good yeman/His name was Robyn Hode/Robyn was a proude outlawe/Whyles he walked on groundeSo curteyse an outlawe as he was one/Was never none yfound”.Robin Hood is described as a ‘yeoman’ – a freeman, and though he is courteous there is not even a hint of the aristocrat he later became. In fact, in the early ballads there is no Maid Marian, no Friar Tuck, Robin does not live in the time of bad Prince John, or the crusades, does not lead a large and merry gang, and certainly never robs the rich to give to the poor. Though he always remains a trickster, and a man with a bow in a wood.Why does this most malleable of myths go through so many changes and so many centuries? And was there ever a real outlaw Robin Hood on whom the ballads, plays, novels and movies are based?With Stephen Knight, Professor of English Literature at Cardiff University and author of Robin Hood: A Mythic Biography; Thomas Hahn, Professor of English Literature at the University of Rochester, New York; Dr Juliette Wood, Secretary of the Folklore Society.

Melvyn Bragg and guests discuss the nature and existence of mathematical infinity. Jonathan Swift encapsulated the counter-intuitive character of infinity with insouciant style:“So, naturalists observe, a fleaHath smaller fleas on him that preyAnd these hath smaller fleas to bite ‘emAnd so proceed ad infinitum.”Alas, the developing utility mathematicians put to the idea of infinity did not find the English philosopher Thomas Hobbes quite so relaxed. When confronted with a diagram depicting an infinite solid whose volume was finite, he wrote, “To understand this for sense, it is not required that a man should be a geometrician or logician, but that he should be mad”. Yet philosophers and mathematicians have continued to grapple with the unending, and it is a core concept in modern maths.So, what is mathematical infinity? Are some infinities bigger than others? And does infinity exist in nature?With Ian Stewart, Professor of Mathematics at the University of Warwick; Robert Kaplan, co-founder of The Math Circle at Harvard University and author of The Art of the Infinite: Our Lost Language of Numbers; Sarah Rees, Reader in Pure Mathematics at the University of Newcastle.

Melvyn Bragg and guests discuss events surrounding the medieval division of the Christian Church. In 1054, Cardinal Humbert stormed into the Cathedral of Constantinople and charged down the aisle. In his hand was a Papal Bull – a deed of excommunication - and he slammed it down onto the altar. As he swept out of the startled church, the Papal Legate and his entourage stopped at the door and symbolically shook the sullied dust of Eastern Christianity from their Catholic boots. The Pope of Rome had decreed that the Patriarch of Constantinople was denied his place in heaven, and soon afterwards the Patriarch excommunicated the Pope in return.It was the culmination of an argument over a single word in the Nicene Creed - but after a thousand years of being one Church, so began a permanent rift.But what were the real underlying reasons behind the split, what were its effects and why did it take until December 1965 for the excommunications to be finally revoked?With Henrietta Leyser, medieval historian and Fellow of St Peter’s College, Oxford; Norman Housley, Professor of Medieval History at the University of Leicester; Jonathan Shepard, editor of the Cambridge History of the Byzantine Empire.

Melvyn Bragg and guests discuss the 19th century Parisian philosophy of life lived for art. In 1848 the young Parisian Henri Murger wrote of his bohemian friends: Their daily existence is a work of genius…they know how to practise abstinence with all the virtue of an anchorite, but if a slice of fortune falls into their hands you will see them at once mounted on the most ruinous fancies, loving the youngest and prettiest, drinking the oldest and best, and never finding sufficient windows to throw their money out of. Then, when their last crown is dead and buried...they go poaching on all the callings that have any connection with art, hunting from morn till night that wild beast called a five franc piece. Bohemianism meant a life lived for art, it meant sexual liberation and freedom from social constraint, but it also meant dodging the landlord and burning your poems to stay warm. How did the garret-philosophy of the Parisian Latin Quarter take over the drawing rooms of Bloomsbury and Chelsea, and why did a French war with necessity emerge as a British life-style as art? With Hermione Lee, Goldsmiths' Professor of English Literature at the University of Oxford and biographer of Virginia Woolf; Virginia Nicholson, author of Among the Bohemians: Experiments in Living 1900-1939; Graham Robb, writer and biographer of Balzac, Victor Hugo and Rimbaud.

Melvyn Bragg and guests discusses the life and ideas of James Clerk Maxwell whose work is not widely known, but whose genius and contribution to the age in which we live is enormous.He took the first colour photograph, defined the nature of gases and with a few mathematical equations expressed all the fundamental laws of light, electricity and magnetism - and in doing so he provided the tools to create the technological age, from radar to radio and televisions to mobile phones. He is credited with fundamentally changing our view of reality, so much so that Albert Einstein said, “One scientific epoch ended and another began with James Clerk Maxwell”. But who was James Clerk Maxwell? What were his ideas, and does this nineteenth century ‘natural philosopher’ deserve a place alongside Newton and Einstein in the pantheon of science? With Simon Schaffer, Reader in History and Philosophy of Science at the University of Cambridge; Peter Harman, Professor of the History of Science at Lancaster University and editor of The Scientific Letters and Papers of James Clerk Maxwell; Joanna Haigh, Professor of Atmospheric Physics at Imperial College London.

Melvyn Bragg and guests discuss the Apocalypse. George Bernard Shaw dismissed it as “the curious record of the visions of a drug addict” and if the Orthodox Christian Church had had its way, it would never have made it into the New Testament. But the Book of Revelation was included and its images of apocalypse, from the Four Horsemen to the Whore of Babylon, were fixed into the Christian imagination and its theology. As well as providing abundant imagery for artists from Durer to Blake, ideas of the end of the world have influenced the response to political, social and natural upheavals throughout history. Our understanding of history itself owes much to the apocalyptic way of thinking. But how did this powerful narrative of judgement and retribution evolve, and how does it still shape our thinking on the deepest questions of morality and history? With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Marina Benjamin, journalist and author of Living at the End of the World; Justin Champion, Reader in the History of Early Modern Ideas at Royal Holloway College, University of London.

Melvyn Bragg and guests discuss the attempt to define humanity’s part in the natural world. In Childe Harold’s Pilgrimage Lord Byron wrote:“There is a pleasure in the pathless woods, There is a rapture on the lonely shore,There is society where none intrudes,By the deep Sea, and music in its roar:I love not man the less, but Nature more.” In the Bible’s book of Genesis, ‘nature’ was the paradise of Eden, but for the philosopher Thomas Hobbes it was a place of perpetual war, where the life of man was “solitary, poore, nasty, brutish and short”. The defining of Nature, whether “red in tooth and claw” or as the fount of all innocence, is an attempt to define man’s origins and purpose and humanity’s part in the natural world. With Jonathan Bate, Professor of English Literature at the University of Warwick; Roger Scruton, Professor of Philosophy at the University of Buckingham; Karen Edwards, Lecturer in English at the University of Exeter.

Melvyn Bragg and guests discuss the formation of volcanoes. In 79AD Mount Vesuvius erupted on the Bay of Naples, buried Pompeii in ash and drowned nearby Herculaneum in lava. The great letter writer Pliny the Younger was staying with his uncle in Misenum and was a witness to the cataclysm. He described it to the historian Tacitus, It seemed as though the sea was being sucked backwards, as if it were being pushed back by the shaking of the land. Certainly the shoreline moved outwards, and many sea creatures were left on dry sand. Behind us were frightening dark clouds, rent by lightning twisted and hurled, opening to reveal huge figures of flame. These were like lightning but bigger. This eruption, which claimed the life of Pliny's uncle, is one of about 500 volcanoes to have erupted in the last two thousand years, some of which are now categorised by vulcanologists as Plinian, after Pliny's famous description.What causes volcanoes? What role do they play in the formation and maintenance of our planet? And is it ever possible to predict when and where they are about to erupt?With Hilary Downes, Professor of Geochemistry at Birkbeck, University of London; Steve Self, Professor of Vulcanology at the Open University; Bill McGuire, Benfield Professor of Geophysical Hazards at University College London.

Melvyn Bragg and guests discuss the private trading company that helped forge the British Empire. At its peak, its influence stretched from western India to eastern China via the farthest reaches of the Indonesian archipelago. It had a fleet of 130 twelve hundred tonne ships and commanded an army of 200,000 troops that came to dominate the Indian subcontinent. It funded governments, toppled princes and generated spectacular amounts of money from trading textiles and spices. But this wasn’t an empire, it wasn’t even a state, it was a company. The East India Company, founded in 1600, lasted for 258 years before the British state gained full control of its activities. In that time it had redrawn the map of India, built an empire and reinvented the fashions and the foodstuffs of Britain. But how did the East India Company become so powerful? How did it change both India and Britain and how was the idea of a company running a country ever accepted by the British Crown?With Huw Bowen, Senior Lecturer in Economic and Social History at the University of Leicester; Linda Colley, School Professor of History at the London School of Economics; Maria Misra, Fellow and Tutor in Modern History at Keble College, Oxford.

Melvyn Bragg and guests discuss the British aristocracy. The Greeks gave us the word aristocracy; it takes its root from ‘aristo’, meaning best and ‘kratos’, meaning rule or power. And for more than five hundred years Britain was ruled by a class that was defined, at the time, as the best. They founded their ascendancy on the twin pillars of land and heredity and in terms of privilege, preferment, power, style and wealth, they dominated British society. As the Earl of Chesterfield confidently informed the House of Lords in the mid-18th century, “We, my lords, may thank heaven that we have something better than our brains to depend upon”. What made the British Aristocracy the one of the most successful power elites in the world? And what brought about its decline?With David Cannadine, Director of the University of London’s Institute of Historical Research and author of The Decline and Fall of the British Aristocracy; Rosemary Sweet, Lecturer in History at the University of Leicester; Felipe Fernandez-Armesto, Professorial Research Fellow at Queen Mary, University of London.

Melvyn Bragg and guests discuss the history and philosophy of warfare. The British historian Edward Gibbon wrote: “Every age, however destitute of science or virtue, sufficiently abounds with acts of blood and military renown.” War, it seems, is one of mankind’s most constant companions, one that has blighted the lives and troubled the minds of men and women from antiquity onwards. Plato envisaged a society without war, but found it had no arts, no culture and no political system. In our own time the United Nations struggles but often fails to prevent the outbreak of conflict. But how has war been understood throughout the ages? Who has it served and how has it been justified? Is war inherent to human beings or could society be organised to the exclusion of all conflict?With Sir Michael Howard, Emeritus Professor of Modern History at the University of Oxford; Angie Hobbs, Lecturer in Philosophy at the University of Warwick; Jeremy Black, Professor of History at the University of Exeter.

Melvyn Bragg and guests discuss the Lunar Society. In the late 18th century, with the ascendant British Empire centred on London, a small group of friends met at a house on the crossroads outside Birmingham and applied their minds to the problems of the age. Between them they managed to launch the Industrial Revolution, discover oxygen, harness the power of steam and pioneer the theory of evolution. They were the Lunar Society, a gathering of free and fertile minds centred on the remarkable quartet of Matthew Boulton, James Watt, Joseph Priestly and Erasmus Darwin. The potter Josiah Wedgwood, another member, summed up the ethos of this group when he said that they were ‘living in an age of miracles in which anything could be achieved’.But how did the Lunar Society operate? What was the blend of religious dissent, entrepreneurial spirit and intellectual adventure that proved so fertile and how did their discoveries permanently change the shape and character of this country?With Simon Schaffer, Reader in History and Philosophy of Science at the University of Cambridge; Jenny Uglow, Honorary Visiting Professor at the University of Warwick and author of The Lunar Men: The Friends who Made the Future; Peter Jones, Professor of French History at the University of Birmingham.

Melvyn Bragg and guests discuss the function and significance of memory. The great writer of remembrance, Marcel Proust, declared “We are able to find everything in our memory, which is like a dispensary or chemical laboratory in which chance steers our hand, sometimes to a soothing drug and sometimes to a dangerous poison”. The memory is vital to life and without it we could not be the people we are, but can it really contain the sum of all our experience? Is it a repository constantly mounting events waiting to be plucked to consciousness, or if not, then under what criteria are memories turfed out?With Martin Conway, Professor of Psychology at Durham University; Mike Kopelman, Professor of Neuropsychiatry at King's College London and St Thomas’ Hospital; Kim Graham, Senior Scientist at the Medical Research Council’s Cognition and Brain Sciences Unit.

Melvyn Bragg and guests discuss blood. For more than 1500 years popular imagination, western science and the Christian Church colluded in a belief that blood was the link between the human and the divine. The Greek physician, Galen, declared that it was blood that contained the force of life and linked the body to the soul, the Christian Church established The Eucharist – the taking of the body and blood of Christ. In our blood was our individuality, it was thought, our essence and our blood lines were special. Transfusion threatened all that and now itself is being questioned.Why is it that blood was used to define both man and messiah? And how has the tradition of blood in religious thought been affected by the progress of medicine?With Miri Rubin, Professor of European History at Queen Mary, University of London; Dr Anne Hardy, Reader in the History of Medicine at the Wellcome Trust Centre for the History of Medicine at University College London; Jonathan Sawday, Professor of English Studies at the University of Strathclyde.

Melvyn Bragg and guests discuss the Holy Grail.Tennyson wrote:“A cracking and a riving of the roofs,And rending, and a blast, and overheadThunder, and in the thunder was a cry.And in the blast there smote along the hallA beam of light seven times more clear than day:And down the long beam stole the Holy Grail”.The sacred allure of the Grail has fascinated writers and ensnared knights for a thousand years. From Malory to Monty Python, it has the richest associations of any artefact in British myth. But where does the story spring from? What does it symbolise and why are its stories so resolutely set in these Isles and so often written by the French?With Dr Carolyne Larrington, Tutor in Medieval English at St John’s College, Oxford; Jonathan Riley-Smith, Dixie Professor of Ecclesiastical History at Cambridge University; Dr Juliette Wood, Associate Lecturer in the Department of Welsh at the University College of Wales in Cardiff.

Melvyn Bragg and guests discusses the Jacobite Rebellion. In the summer of 1745, a young man in a small French frigate landed on the West Coast of Scotland. It was Bonnie Prince Charlie who began his campaign to become king of Scotland and England. He had seven followers amongst his shipmates and took to the Highlands to raise an army from the Scottish clans: “The Highland clans with sword in hand Frae John o Groats tae AirlieHae tae a man declared to standOr fa wi Royal Charlie”.Or so the old Jacobite song goes. But why was the latest scion of the Stuart dynasty such a favourite with the Scottish Highlanders? And did Bonnie Prince Charlie ever have a real chance of gaining the throne of England? With Murray Pittock, Professor of English Literature at the University of Strathclyde; Stana Nenadic, Senior Lecturer in Social History at Edinburgh University; Allan Macinnes, Burnett-Fletcher Professor of History at Aberdeen University.

Melvyn Bragg and guests discuss the Romans in Britain. About 2000 years ago, Tacitus noted that “the climate is wretched”, Herodian said, “the atmosphere in the country is always gloomy”, Dio said “they live in tents unclothed and unshod, and share their women” and the historian Strabo said on no account should the Romans make it part of the Empire because it will never pay its way. But invade they did, and Britain became part of the Roman Empire for almost four hundred years.But what brought Romans to Britain and what made them stay? Did they prove the commentators wrong and make Britain amount to something in the Empire? Did the Romans come and go without much trace, or do those four centuries still colour our national life and character today?With Greg Woolf, Professor of Ancient History at St Andrews University; Mary Beard, Reader in Classics at Cambridge University; Catharine Edwards, Lecturer in Classics and Ancient History at Birkbeck College, London University.

Melvyn Bragg and guests discuss the idea of youth. In 1898 Joseph Conrad wrote, “I remember my youth and the feeling that will never come back any more – the feeling that I could last for ever, outlast the sea, the earth, and all men; the deceitful feeling that lures us on to perils, to love, to vain effort – to death…”From antiquity to our own time, the concept of youth, with its promise of possibility and adventure, has been greeted with fascination as well as fear. The ancient Greeks saw the period of youth as dangerous and unpredictable, but how did they seek to control it? How did the Renaissance celebrate the ideals and intellect of youth? Why was 19th century British society so preoccupied with the moral well-being of young people? And does a distinct youth culture still exist? With Tim Whitmarsh, Lecturer in Hellenistic Literature at Exeter University; Thomas Healy, Professor of Renaissance Studies at Birkbeck College, London; Deborah Thom, Lecturer in History at Robinson College, Cambridge.

Melvyn Bragg and guests discuss the life and work Marcel Proust whose novel À La Recherche du Temps Perdu, or In Search of Lost Time, has been called the definitive modern novel. His stylistic innovation, sensory exploration and fascination with memory were to influence a whole body of thinkers, from the German intellectuals of the 1930s to the Bloomsbury set, chief among them Virginia Woolf, and innumerable critics and novelists since. But how did he succeed in creating a 3000 page novel with such an artistic coherence? To what extent did John Ruskin influence Proust? Is his fascination with memory and recall simply a nostalgia for the past? And what impact did he have on the 20th century novel? With Jacqueline Rose, Professor of English Literature at Queen Mary, University of London and author of Albertine; Malcolm Bowie, Master of Christ’s College, Cambridge and author of Proust among the Stars; Dr Robert Fraser, Senior Research Fellow in the Literature Department at the Open University and author of Proust and the Victorians.

Melvyn Bragg and guests discuss the Spanish Civil War which was a defining war of the twentieth century. It was a brutal conflict that polarised Spain, pitting the Left against the Right, the anti-clericals against the Church, the unions against the landed classes and the Republicans against the Monarchists. It was a bloody war which saw, in the space of just three years, the murder and execution of 350,000 people. It was also a conflict which soon became internationalised, becoming a battleground for the forces of Fascism and Communism as Europe itself geared up for war.But what were the roots of the Spanish Civil War? To what extent did Franco prosecute the war as a religious crusade? How did Franco institutionalise his victory after the war? And has Spain fully come to terms with its past?With Paul Preston, Principe de Asturias Professor of Contemporary Spanish History at the London School of Economics; Helen Graham, Professor of Spanish History at Royal Holloway, University of London; Dr Mary Vincent, Senior Lecturer in the Department of History at Sheffield University.

Melvyn Bragg and guests discuss the life cycle of stars. In his poem Bright Star John Keats wrote, "Bright Star, would I were steadfast as thou art". For Keats the stars were symbols of eternity- they were beautiful and ordered and unchanging - but modern astronomy tells a very different story. Stars, like everything else in the universe, are subject to change. They are born among vast swirls of gas and dust and they die in the stunning explosions we call supernovae. They create black holes and neutron stars and, in the very beginning of the universe, they forged the elements from which all life is made. But how do stars keep burning for millions of years, why do they self-destruct with such ferocity and what will happen to the universe when they all go out?With Paul Murdin, Senior Fellow at the Institute of Astronomy, Cambridge; Janna Levin, Advanced Fellow in Theoretical Physics in the Department of Applied Mathematics & Theoretical Physics at the University of Cambridge; Phil Charles, Professor of Astronomy at Southampton University.

Melvyn Bragg and guests explore the creative force of originality. How far is it to do with origins, how far with the combination of the discoveries of others, which were themselves based on the thoughts of others, into an ever-receding and replicating past? Is invention original? Is original important? Is tradition more interesting and the reworking of what is traditional of greater value than the search for idiosyncrasy? And did our notion of the original genius come as much out of a commercial imperative for individual copyright in the eighteenth century, as a romantic view of human nature which came in, perhaps not co-incidentally, at the same time? In 1800, in his preface to Lyrical Ballads, Wordsworth wrote "Every great and original writer, in proportion as he is great and original, must himself create the taste by which he is to be relished". But did the notion of originality begin with the Romantics in the 18th century, or has society always valued originality? Should we consider Shakespeare an innovator or a plagiarist?To what extent is originality about perception rather than conception and is originality a concept without meaning today?With John Deathridge, King Edward Professor of Music at King’s College London; Jonathan Rée, philosopher and author of Philosophical Tales; Professor Catherine Belsey, Chair of the Centre for Critical and Cultural Theory at Cardiff University

Melvyn Bragg and guests discuss redemption. In St Paul's letter to the Galatians, he wrote: "Christ has set us free; stand fast therefore, and do not submit again to a yoke of slavery". This conception of Redemption as freedom from bondage is crucial for Judeo-Christian thought. In Christianity, the liberation is from original sin, a transformation from the Fall to salvation - not just for mankind but for individual human beings. The content of that journey is moral, gaining redemption by becoming better.So why is the idea of transformation so appealing to human beings? To what extent were Christian views of Redemption borrowed from Judaism? How did philosophers such as Marx reinterpret the concept of Redemption and can redemption retain its value in a world without God? Does its continuing power signify a deep psychological need in humankind?With Richard Harries, Bishop of Oxford; Janet Soskice, Reader in Modern Theology and Philosophical Theology at Cambridge University; Stephen Mulhall, Fellow and Tutor in Philosophy at Oxford University.

Melvyn Bragg and guests discuss meteorology. The Book of Genesis resounds with a terrible act of vengeance, carried out by an angry God seeking to punish his people. And the mechanism with which this is carried out - a catastrophic flood which wipes out evil on earth. In fact, many ancient civilisations believed extreme meteorological phenomena like thunder and lightning, hailstones and even meteors were acts of divine intervention. Running parallel with this belief, however, was also a desire to understand and explain the natural world through rational enquiry and observation. This complex relationship – between the natural world and divinity – has fascinated philosophers, artists and scientists alike from antiquity to our own time. Aristotle, for example, coined the phrase meteorology but to what extent did he link meteorological events to the cosmos and the Gods? How did the development of instrumentation during the Renaissance aid the prediction of weather events? Why did 18th century writers such as Keats feel that these scientific advances stripped the skies of its mystique and romance? And why does meteorology continue to fascinate and mystify to this day? With Vladimir Jankovic, Wellcome Research Lecturer at the Centre for the History of Science, Technology and Medicine at Manchester University;Richard Hamblyn, writer; Liba Taub, Director of the Whipple Museum of the History of Science at Cambridge University.

Melvyn Bragg and guests discuss the Aztec Empire. According to legend, the origins of it lie on a mythical island called Aztlan - "place of the white herons" - in the north of Mexico. From there this nomadic group of Mesoamericans are said to have undertaken a pilgrimage south to the fertile valleys of Central America. In the space of just 200 years, they formed what has been called the largest, and arguably the most ruthless, pre-Hispanic empire in North America which, at its zenith, was to rule over approximately 500 small states, comprising by the 16th century some 6 million people. Was it military might and intimidation alone that helped the Aztecs extend their power? What part did their complex belief system play in their imperial reach? Their use of human sacrifice has been well documented, but how widespread actually was it? How easily were the Spanish conquistadors able to Christianise this empire? And what legacy did the Aztecs leave behind that lives on in our world today?With Alan Knight, Professor of the History of Latin America at Oxford University and author of Mexico: From the Beginning to the Spanish Conquest; Adrian Locke, co-curator of the Aztecs exhibition at the Royal Academy of Arts; Elizabeth Graham, Senior Lecturer in Mesoamerican Archaeology at University College London.

Melvyn Bragg and guests discuss the Lindisfarne Gospels. In 597 Pope Gregory the Great ordered that a mission of monks be sent from Rome to convert Britain to its own brand of Christianity - lest it be submerged by the pagan beliefs of the Anglo-Saxon overlords. Just over 100 years later, the Lindisfarne Gospels were produced - lavish and ornate manuscripts, central to the story of how Britain came to be unified by the flag of the Roman Church – and they came to embody a set of beliefs and ideas that dominated Britain for a thousand years. Was the Rome mission in the 6th century the only strand of Christianity to sweep through Britain? Why did Northumbria become a key battleground for ideological dispute? How successful were the Lindisfarne Gospels in unifying the different strands of Christianity? To what extent did they serve as a founding statement of Christian identity in Britain?With Dr Michelle Brown, Curator of Illuminated Manuscripts at the British Library and author of A Guide to Western Historical Scripts: From Antiquity to 1600; Dr Richard Gameson, Reader in Medieval History at Kent University and editor of St Augustine and the Conversion of England; Professor Clare Lees, Professor of Medieval Literature at King's College London and author of Tradition and Belief: Religious Writing in Late Anglo-Saxon England.

Melvyn Bragg and guests discuss the theories of a grand design in the universe. The late evolutionary biologist Stephen Jay Gould argued that if you re-ran the tape of evolutionary history, an entirely different set of creatures would emerge. Man would not exist because the multitude of random changes that resulted in us would never be repeated exactly the same way. Others disagree, arguing that there is a pattern that points to some kind of direction – even, perhaps, a design, a sense that some things are pre-ordained. Who were the original proponents of the idea of a grand design? Were they deliberately setting out to find a scientific theory that could sit alongside religious faith? On the other hand, can the concept of contingency – or the randomness of evolution - be compatible with a belief in God? With Simon Conway Morris, Professor of Evolutionary Palaeobiology at Cambridge University and author of The Crucible of Creation – the Burgess Shale and the Rise of Animals; Sandy Knapp, botanist at the Natural History Museum; John Brooke, Andreas Idreos Professor of Science and Religion at Oxford University.

Melvyn Bragg and guests discuss the history of the epic. In his essay 'Why the novel matters', DH Lawrence argued that the novel contained all aspects of life. Perhaps better placed to make that claim is the epic. From tackling questions of identity, history, warfare, mortality and the ways of the Gods to narrating tales of magic and supernatural creatures, it was the Greek and Roman poems of Homer and Virgil that underpinned and explained the position of men in the world. And it was these narratives of heroic actions and grand deeds that were to form a template from which many future epics would be constructed from Chaucer's Troilus and Cressayde to Milton’s Paradise Lost. But who are the heroes of these epics? To what extent was the classical epic a political project, a means of creating a founding myth for empire? How did the Renaissance revive the form and how successful were writers such as Milton in rendering the Christian story an epic? And what does the novel owe to the epic?With, John Carey, Emeritus Professor of English Literature at Oxford University; Karen Edwards, Lecturer in English at Exeter University; Oliver Taplin, Professor of Classical Languages and Literature at the University of Oxford.

Melvyn Bragg and guests discuss the calendar, which shapes the lives of millions of people. It is an invention that gives meaning to the passing of time and orders our daily existence. It links us to the arcane movements of the heavens and the natural rhythms of the earth. It is both deeply practical and profoundly sacred. But where does this strange and complex creation come from? Why does the week last seven days but the year twelve months? Who named these concepts and through them shaped our lives so absolutely? The answers involve Babylonian Astronomers and Hebrew Theologians, Roman Emperors and Catholic Popes. If the calendar is a house built on the shifting sands of time, it has had many architects. With Robert Poole, Reader in History at St Martin’s College Lancaster and author of Time’s Alteration, Calendar Reform in Early Modern England; Kristen Lippincott, Deputy Director of the National Maritime Museum in Greenwich; Peter Watson, Research Associate at the McDonald Institute for Archaeological Research at Cambridge University and author of A Terrible Beauty – A History of the People and Ideas that Shaped the Modern Mind.

Melvyn Bragg and guests discuss man and disease. The Book of Exodus makes clear that when God wants to strike humankind, he does so with plague and disease. For millennia epidemics were understood exactly that way - as acts of divine retribution, a force of nature that could devastate empires and annihilate great swathes of population at a stroke. From the bubonic plague to measles, from cholera to smallpox, epidemics have constantly reshaped our world, leaving destruction and huge social upheaval in their wake. Before advanced science, what defences did humankind have? How much did the ancient Greeks understand of the root causes of disease - or did they simply explain it as an imbalance of the four humours that governed the body? What were the social and political consequences of The Black Death of 14th century Europe which wiped out a third of the population? How did the scientific breakthroughs of the 19th century - and the discovery of germ theory - alter people's perception of disease? And is it possible to live in a disease free society? How have we understood these afflictions, how have we fought against them and is it a war we can ever win?With Dr Anne Hardy, Reader in the History of Medicine at the Wellcome Trust Centre at University College London; David Bradley, Professor of Tropical Hygiene at the London School of Hygiene and Tropical Medicine; Dr Chris Dye, epidemiologist with the World Health Organisation.

Melvyn Bragg and guests discuss the Scottish Enlightenment of the 18th century. In 1696 the Edinburgh student, Thomas Aitkenhead, claimed theology was "a rhapsody of feigned and ill invented nonsense". He was hanged for his trouble - just one victim of a repressive religious society called the Scottish Kirk. Yet within 60 years Scotland was transformed by the ideas sweeping the continent in what we call the Enlightenment. This Scottish Enlightenment emerged on a broad front. From philosophy to farming it championed empiricism, questioned religion and debated reason. It was crowned by the philosophical brilliance of David Hume and by Adam Smith – the father of modern economics. But what led to this ‘Scottish Miracle’, was it an indigenous phenomenon or did it depend on influence from abroad? It profoundly influenced the American revolutionaries and the British Empire, but what legacy does it have for Scotland today?With Professor Tom Devine, Director of the Research Institute of Irish and Scottish Studies at the University of Aberdeen; Karen O’Brien, Reader in English and American Literature at the University of Warwick; Alexander Broadie, Professor of Logic and Rhetoric at the University of Glasgow.
