In Our Time

Melvyn Bragg and guests discuss the 19th century American writer and philosopher, Henry David Thoreau. Anti-slavery activist and passionate environmentalist, Thoreau was above all a champion of self-reliance and individualism. He was also a champion of the simple life, a lover of nature and an enemy of the modern who lived alone in a log cabin in the woods away from society. In his seminal work, Walden, published in 1854, he wrote: “I went to the woods because I wished to live deliberately, to front only the essential facts of life and not, when I came to die, discover that I had not lived. I wanted to live deep and suck out all the marrow of life.” Thoreau has become emblematic of one version of American values and his work has been an inspiration to politicians and writers alike, from Martin Luther King to Gandhi, Yeats and Tolstoy. Yet in many ways Thoreau remains a mystery, a man of contradictions who advocated self-sufficiency but was happy to let his mother do his washing and cook his meals.With Kathleen Burk, Professor of American History at University College London; Tim Morris, Lecturer in American Literature at the University of Dundee; Stephen Fender, Honorary Professor in English Literature at University College London.

Melvyn Bragg and guests discuss the consolation of Philosophy. In the 6th century AD, a successful and intelligent Roman politician called Boethius found himself unjustly accused of treason. Trapped in his prison cell, awaiting a brutal execution, he found solace in philosophical ideas - about the true nature of reality, about injustice and evil and the meaning of living a moral life. His thoughts did not save him from death, but his ideas lived on because he wrote them into a book. He called it The Consolation of Philosophy. The Consolation of Philosophy was read widely and a sense of consolation is woven into many philosophical ideas, but what for Boethius were the consolations of philosophy, what are they more generally and should philosophy lead us to consolation or lead us from it?With AC Grayling, Professor of Philosophy at Birkbeck College, University of London; Melissa Lane, Senior University Lecturer in History at the University of Cambridge and Roger Scruton, Research Professor at the Institute for the Psychological Sciences.

Melvyn Bragg and guests discuss the physics of time. When writing the Principia Mathematica, Isaac Newton declared his hand on most of the big questions in physics. He outlined the nature of space, explained the motions of the planets and conceived the operation of gravity. He also laid down the law on time declaring: “Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external.” For Newton time was absolute and set apart from the universe, but with the theories of Albert Einstein time became more complicated; it could be squeezed and distorted and was different in different places.Time is integral to our experience of things but we find it very difficult to think about. It may not even exist and yet seems written into the existence of absolutely everything. With Jim Al-Khalili, Professor of Theoretical Physics and Chair in the Public Engagement in Science at the University of Surrey; Monica Grady, Professor of Planetary and Space Sciences at the Open University and Ian Stewart, Professor of Mathematics at the University of Warwick.

Melvyn Bragg and guests discuss the history of scientific ideas about heat. As anyone who’s ever burnt their hand will testify – heat is a pretty commonplace concept. Cups of coffee cool down, microwaves reheat them, water boils at 100 degrees and freezes on cold winter nights.Behind the everyday experience of hot things lies a complex story of ideas spread across Paris, Manchester and particularly Glasgow. It’s a story of brewing vats and steam engines, of fridges, thermometers and the heat death of the universe. But most importantly, it was the understanding and harnessing of heat that helped make the modern world of industry, engineering and technology.With Simon Schaffer, Professor of History of Science at the University of Cambridge and Fellow of Darwin College; Hasok Chang, Professor of Philosophy of Science at University College London and Joanna Haigh, Professor of Atmospheric Physics at Imperial College London

Melvyn Bragg and guests discuss the Great Reform Act of 1832. The Act redrew the map of British politics in the wake of the Industrial Revolution and is a landmark in British political history.“We must get the suffrage, we must get votes, that we may send the men to Parliament who will do our work for us; …and we must have the country divided so that the little kings of the counties can't do as they like, but must be shaken up in one bag with us.” So declares a working class reformist in George Eliot’s novel Felix Holt: the Radical. It is set in 1832, the year of the so-called “Great Reform Act” which extended the vote and gave industrial cities such as Manchester and Birmingham political representation for the first time. But to what extent was Britain’s political system transformed by the Great Reform Act? What were the causes of reform in the first place and was the Act designed to encourage democracy in Britain or to head it off?

Melvyn Bragg and guests examine the relationship between the mind and the brain as they discuss recent developments in Neuroscience. In the mid-19th century a doctor had a patient who had suffered a stroke. The patient was unable to speak save for one word. The word was ‘Tan’ which became his name. When Tan died, the doctor discovered damage to the left side of his brain and concluded that the ability to speak was housed there. This is how neuroscience used to work – by examining the dead or investigating the damaged – but now things have changed. Imaging machines and other technologies enable us to see the active brain in everyday life, to observe the activation of its cells and the mass firing of its neuron batteries. Our extraordinary new knowledge of how the brain works has challenged concepts of free will and consciousness and opened up new ways of understanding the brain. Yet these new ideas seem to conform to some old ideas such as Freudian Psychoanalysis. But what picture of the brain has emerged, how has our understanding of it changed and what are the implications for understanding that most mysterious and significant of all phenomena – the human mind?With Martin Conway, Professor of Psychology at the University of Leeds; Gemma Calvert, Professor of Applied Neuroimaging at WMG, University of Warwick and David Papineau, Professor of Philosophy of Science at King’s College London.

Melvyn Bragg and guests discuss The Great Fire of London which destroyed up to a third of the city in 1666. Samuel Pepys described the scene in his diary:“all over the Thames, with one's face in the wind, you were almost burned with a shower of firedrops…and in corners and upon steeples, and between churches and houses, as far as we could see up the hill of the City, we saw the fire …It made me weep to see it.”The London that rose from the ashes was a visible manifestation of ideas; of the politics, religion, economics and science of the heady Restoration period. Christopher Wren, of course, but also Robert Hooke, The Royal Society, St Paul’s Cathedral, the Restoration court of Charles II and, inevitably, building regulations. With Lisa Jardine, Centenary Professor of Renaissance Studies at Queen Mary, University of London; Vanessa Harding, Reader in London History at Birkbeck, University of London and Jonathan Sawday, Professor of English Studies at the University of Strathclyde

Melvyn Bragg and guests discuss one of the most important works of political philosophy ever written - Aristotle’s ‘Politics’. Looking out across the city states of 4th century Greece Aristotle asked what made a society good and developed a language of ‘oligarchies’, ‘democracies’ and ‘monarchies’ that we still use today. Having witnessed his home town of Stagira destroyed by Philip of Macedon, Aristotle tried to establish a way of preserving a good society in dangerous times. How should it be governed and who should be allowed to live in it? Thomas Hobbes, Jean-Jacques Rousseau, Thomas Aquinas and Niccolo Machiavelli, to name but a few, have all asked the same questions and come up with wildly differing answers.Aristotle’s conclusions range across the role of wealth and the law, across men, women and slaves, education and leisure. They are far reaching, influential and, at times, deeply unpalatable. But they are also answers to questions that have not and will not go away. With Angie Hobbs, Associate Professor of Philosophy at the University of Warwick; Paul Cartledge, AG Leventis Professor of Greek Culture at the University of Cambridge and Annabel Brett, Senior Lecturer in History at the University of Cambridge.

Melvyn Bragg and guests discuss the life and times of Simon Bolivar, hero of the revolutionary wars that liberated Spanish America from Spain. In 1804 Bolivar stood on a small hill in Rome and made a grand declaration. He said, “I swear before you, I swear before the God of my fathers, I swear by my fathers, I swear by my honour, I swear by my country that I will not rest, body or soul, until I have broken the chains with which Spanish power oppresses us.” Unlike most teeenage declarations, Bolivar made good on his word. A wealthy young man, Bolivar was inspired by Enlightenment thinkers John Locke and Jean Jacques Rousseau and by the compelling personality of Napoleon. His story is one of ideas and adventure, of armies crossing the Andes, of the far flung influence of the Napoleonic Wars and an unexpectedly large role for Britain. But when he died he was anything but a hero, his reputation undergoing a transformation after his death to make him an icon of liberation and the national hero of Venezuela, Columbia, Equador, Peru and Bolivia – a country that bears his name. With Anthony McFarlane, Professor of Comparative American Studies at the University of Warwick; John Fisher, Professor of Latin American History at the University of Liverpool and Catherine Davies, Professor in the Department of Spanish, Portuguese and Latin American Studies at the University of Nottingham.

Melvyn Bragg and guests discuss the culture of the Baroque. What do the music of Bach, the Colonnades of St Peter’s, the paintings of Caravaggio and the rebuilding of Prague have in common? The answer is the Baroque – a term used to describe a vast array of painting, music, architecture and sculpture from the 17th and 18th centuries.Baroque derives from the word for a misshapen pearl and denotes an art of effusion, drama, grandeur and powerful emotion. Strongly religious it became the aesthetic of choice of absolute monarchs. But the more we examine the Baroque, the more subtle and mysterious it becomes. It is impossible to discuss 17th century Europe without it, yet it is increasingly hard to say what it is. It was coined as a term of abuse, denounced by thinkers of the rational Enlightenment and by Protestant cultures which read into Baroque the excess, decadence and corruption they saw in the Catholic Church. With Tim Blanning, Professor of Modern European History and Fellow of Sidney Sussex College, University of Cambridge; Nigel Aston, Reader in Early Modern History at the University of Leicester and Helen Hills, Professor of Art History at the University of York

Melvyn Bragg and guests discuss Vitalism, an 18th and 19th century quest for the spark of life. On a dreary night in November 1818, a young doctor called Frankenstein completed an experiment and described it in his diary: “I collected the instruments of life around me, that I might infuse a spark of being into the lifeless thing that lay at my feet…By the glimmer of the half-extinguished light, I saw the dull yellow eye of the creature open…”Frankenstein may seem an outlandish tale, but Mary Shelley wrote it when science was alive with ideas about what differentiated the living from the dead. This was Vitalism, a belief that living things possessed some spark of life, some vital principle, perhaps even a soul, that distinguished the quick from the dead and lifted them above dull matter. Electricity was a very real candidate; when an Italian scientist called Luigi Galvani made dead frogs twitch by applying electricity he thought he had found it. Vitalists aimed at unlocking the secret of life itself and they raised questions about what life is that are unresolved to this day. With Patricia Fara, Fellow of Clare College and Affiliated Lecturer in the Department of History and Philosophy of Science at Cambridge University; Andrew Mendelsohn, Senior Lecturer in the History of Science and Medicine at Imperial College, University of London and Pietro Corsi, Professor of the History of Science at the University of Oxford.

Melvyn Bragg and guests discuss an iconic piece of 20th century maths - Gödel’s Incompleteness Theorems. In 1900, in Paris, the International Congress of Mathematicians gathered in a mood of hope and fear. The edifice of maths was grand and ornate but its foundations, called axioms, had been shaken. They were deemed to be inconsistent and possibly paradoxical. At the conference, a young man called David Hilbert set out a plan to rebuild the foundations of maths – to make them consistent, all encompassing and without any hint of a paradox. Hilbert was one of the greatest mathematicians that ever lived, but his plan failed spectacularly because of Kurt Gödel. Gödel proved that there were some problems in maths that were impossible to solve, that the bright clear plain of mathematics was in fact a labyrinth filled with potential paradox. In doing so Gödel changed the way we understand what mathematics is and the implications of his work in physics and philosophy take us to the very edge of what we can know.With Marcus du Sautoy, Professor of Mathematics at Wadham College, University of Oxford; John Barrow, Professor of Mathematical Sciences at the University of Cambridge and Gresham Professor of Geometry and Philip Welch, Professor of Mathematical Logic at the University of Bristol.

Melvyn Bragg and guests discuss one of the greatest intellectual projects in history - the mass translation of Greek ideas into Arabic from the 9th century onwards.One night in Baghdad, the 9th century Caliph Al-Mamun was visited by a dream. The philosopher Aristotle appeared to him, saying that the reason of the Greeks and the revelation of Islam were not opposed. On waking, the Caliph demanded that all of Aristotle’s works be translated into Arabic. And they were. And it wasn’t just Aristotle. Over the next 200 years Greek philosophy, medicine, engineering and maths were all poured and sometimes squeezed into Arabic. Centred on Baghdad, this translation movement introduced the Islamic world to the philosophy of Aristotle, the geometry of Euclid and the Medicine of Galen. It caused an intellectual ferment that demanded the creation of new words to explain new concepts and house new arguments. Over 600 years before the European renaissance the intellectual legacy of Greece was woven into the tapestry of Arabic thought and it was only through the Arabic versions that Europe go its hands on many Greek ideas. With Peter Adamson, Reader in Philosophy at King’s College London; Amira Bennison, Senior Lecturer in Middle Eastern and Islamic Studies at the University of Cambridge; and Peter Pormann, Wellcome Trust Assistant Professor in Classics and Ancient History at the University of Warwick

Melvyn Bragg and guests discuss the parting of the Red Sea, the feeding of the five thousand and the general subject of miracles. Miracles have been part of human culture for thousands of years. From St Augustine in the 4th century through the medieval cult of saints to David Hume in the 18th, miracles have captured the imaginations of believers and sceptics alike. The way they have been celebrated, interpreted, dissected and refuted is a whole history of arguments between philosophy, science and religion. They have also been used by the corrupt and the powerful to gain their perverse ends. Miracles have been derided and proved to be fraudulent and yet, for many, the miraculous maintain a grip on our imagination, our language and our belief to this day. With Martin Palmer, Director of the International Consultancy on Religion, Education and Culture;Janet Soskice, Reader in Philosophical Theology at Cambridge University; Justin Champion, Professor of the History of Early Modern Ideas at Royal Holloway, University of London.

Melvyn Bragg and guests discuss the Roman historian Tacitus who chronicled some of Rome’s most notorious emperors, including Nero and Caligula, and whose portrayal of Roman decadence influences the way we see Rome today. “The story I now commence is rich in vicissitudes, grim with warfare, torn by civil strife, a tale of horror even during times of peace”. So reads page one of The Histories by the Roman historian Tacitus and it doesn’t disappoint. Convinced that Rome was going to the dogs, Tacitus depicts a Rome which is a hotbed of sex and violence, of excessive wealth and senatorial corruption. His work is a pungent study in tyranny and decline that has influenced depictions of Rome, from Gibbon’s Decline and Fall to Robert Graves’ I, Claudius. But is it a true picture of the age or does Tacitus’ work present the tyranny and decadence of Rome at the expense of its virtues? And to what extent, when we look at the Roman Empire today, do we still see it through Tacitus' eyes?With Catharine Edwards, Professor of Classics and Ancient History at Birkbeck, University of London; Ellen O’Gorman, Senior Lecturer in Classics at the University of Bristol and Maria Wyke, Professor of Latin at University College London

Melvyn Bragg and guests discuss Dante’s ‘Inferno’ - a medieval journey through the nine circles of Hell. “Abandon hope, all ye who enter here”. This famous phrase is written above the gate of Hell in a 14th century poem by the Italian poet Dante Alighieri. The poem is called the ‘Divine Comedy’ and Hell is known as ‘Dante’s Inferno’. It is a lurid vision of the afterlife complete with severed heads, cruel and unusual punishments and devils in frozen lakes. But the inferno is much more than a trip into the macabre - it is a map of medieval spirituality, a treasure house of early renaissance learning, a portrait of 14th century Florence, and an acute study of human psychology. It is also one of the greatest poems ever written. With, Margaret Kean, University Lecturer in English and College Fellow at St Hilda’s College, University of Oxford; John Took, Professor of Dante Studies at University College London and Claire Honess, Senior Lecturer in Italian at the University of Leeds and Co-Director of the Leeds Centre for Dante Studies.

Melvyn Bragg and guests discuss the Arab conquests - an extraordinary period in the 7th and 8th centuries when the tribes of the Arabian Peninsula conquered the Middle East, Persia, North Africa and Southern Europe and spread the ideas of the Islamic religion. In 632 the prophet Muhammad died and left behind the nascent religion of Islam among a few tribes in the Arabian Desert. They were relatively small in number, they were divided among themselves and they were surrounded by vast and powerful empires. Yet within 100 years Arab armies controlled territory from Northern Spain to Southern Iran and Islamic ideas had begun to profoundly refashion the societies they touched. It is one of the most extraordinary and significant events in world history that began the slow and profound transformation of Greek and Persian societies into Islamic ones. But how did the Arab armies achieve such extensive victories, how did they govern the people they conquered and what was the relationship between the achievements of the Arabs and the religious beliefs they carried with them?With Hugh Kennedy, Professor of Arabic at the School of Oriental and African Studies, University of London; Amira Bennison, Senior Lecturer in Middle Eastern and Islamic Studies at the University of Cambridge and Robert Hoyland, Professor in Arabic and Middle East Studies at the University of St Andrews

Melvyn Bragg and guests discuss the music of the spheres, the elegant and poetic idea that the revolution of the planets generates a celestial harmony of profound and transcendent beauty. In Shakespeare’s The Merchant of Venice the young Lorenzo woos his sweetheart with talk of the stars: “There’s not the smallest orb which thou behold’stBut in his motion like an angel sings,Still quiring to the young-eyed cherubins;Such harmony is in immortal souls;But whilst this muddy vesture of decayDoth grossly close it in, we cannot hear it.”The idea of music of the spheres ran through late antiquity and the medieval period into the Renaissance and its echoes could be heard in astrology and astronomy, in theology, and, of course, in music itself. Influenced by Pythagoras and Plato, it was discussed by Cicero, Boethius, Marcello Ficino and Johannes Kepler It affords us a glimpse into minds for which the universe was full of meaning, of strange correspondences and grand harmonies.With Peter Forshaw, Postdoctoral Fellow at Birkbeck, University of London; Jim Bennett, Director of the Museum of the History of Science at the University of Oxford and Angela Voss, Director of the Cultural Study of Cosmology and Divination at the University of Kent, Canterbury.

Melvyn Bragg and guests discuss the Metaphysical poets, a diffuse group of 17th century writers including John Donne, Andrew Marvell and George Herbert. Mourning the death of a good friend in 1631, the poet Thomas Carew declared: “The Muses' garden, with pedantic weeds O'erspread, was purg'd by thee; the lazy seeds Of servile imitation thrown away, And fresh invention planted.”The gardener in question was a poet, John Donne, and from his fresh invention blossomed a group of 17th century writers called the metaphysical poets. Concerned with sex and death, with science and empire, the metaphysical poets challenged the conventions of Elizabethan poetry with drama and with wit. And they showed that English, like Italian and French, was capable of true poetry.Unashamedly modern, they were saluted by another great modernist, T.S. Eliot, who admired their genius for imagery, the freshness of their language and the drama of their poetic character. But what do we mean by metaphysical poetry, how did it reflect an age of drama and discovery and do poets as different as John Donne, Andrew Marvell and George Herbert really belong together in the canon of English literature? With Tom Healy, Professor of Renaissance Studies at Birkbeck College, University of London; Julie Sanders, Professor of English Literature and Drama at the University of Nottingham; and Tom Cain, Professor of Early Modern Literature at the University of Newcastle upon Tyne

Melvyn Bragg and guests discusses the prescient thriller ‘The Riddle of the Sands’ about the decline Anglo-German relations before the First World War. In 1903 an Englishman called Charles Caruthers went sailing in the North Sea and stumbled upon a German military plot. The cunning plan was to invade the British Isles from the Frisian Islands using special barges. The plucky Caruthers foiled the plot and returned to his sailing holiday.This is not history but fiction, an immensely popular book called ‘The Riddle of the Sands’ by Erskine Childers. It was a prescient vision of two nations soon to fight the First World War but it went against the spirit of the previous century. Brits and Germans had fought together at Waterloo and had influenced profoundly each other’s thought and art. They even shared a royal family. Yet somehow victory at Waterloo and the shared glories of Romanticism became the mutual tragedy of the Somme.With Richard Evans, Professor of Modern History at the University of Cambridge; Rosemary Ashton, Quain Professor of English Language and Literature at University College London and Tim Blanning, Professor of Modern European history at The University of Cambridge.

Melvyn Bragg and guests delve into the dark world of genetics under Joseph Stalin in discussing the career of Trofim Lysenko. In 1928, as America lurched towards the Wall Street Crash, Joseph Stalin revealed his master plan - nature was to be conquered by science, Russia to be made brutally, glitteringly modern and the world transformed by communist endeavour.Into the heart of this vision stepped Trofim Lysenko, a self-taught geneticist who promised to turn Russian wasteland into a grain-laden Garden of Eden. Today, Lysenko is a byword for fraud but in Stalin’s Russia his outlandish ideas about genetic inheritance and evolution became law. They reveal a world of science distorted by ideology, where ideas were literally a matter of life and death. To disagree with Lysenko risked the gulag and yet he destroyed Soviet Agriculture and damaged, perhaps irreparably, the Soviet Union’s capacity to fight and win the Cold War. With Robert Service, Professor of Russian History at the University of Oxford; Steve Jones, Professor of Genetics at University College London; Catherine Merridale, Professor of Contemporary History at Queen Mary, University of London.

Melvyn Bragg and guests discuss the strange mathematics of probability where heads or tails is a simple question with a far from simple answer. Gambling may be as old as the hills but probability as a mathematical discipline is a relative youngster. Probability is the field of maths relating to random events and, although commonplace now, the idea that you can pluck a piece of maths from the tumbling of dice, the shuffling of cards or the odds in the local lottery is a relatively recent and powerful one. It may start with the toss of a coin but probability reaches into every area of the modern world, from the analysis of society to the decay of an atom. With Marcus du Sautoy, Professor of Mathematics at the University of Oxford; Colva Roney-Dougal, Lecturer in Pure Mathematics at the University of St Andrews; Ian Stewart, Professor of Mathematics at the University of Warwick

Melvyn Bragg and guests discuss how the Black Death influenced the structure and ideas of Medieval Europe. In October 1347, a Genoese trading ship arrived at the busy port of Messina in Sicily and docked among many similar ships doing similar things. But this ship was special because this ship had rats and the rats had fleas and the fleas had plague. This was the Black Death and its terrible progress was captured by the Florentine writer Giovanni Boccaccio who declared “in those years a dead man was then of no more account than a dead goat”. In the long and unsanitary history of Europe there have been many plagues but only one Black Death. It killed over a third of Europe’s population in 4 years – young and old, rich and poor, in the town and in the country. When it stopped in 1351 it left a continent ravaged but transformed – the poor found their labour to be valuable, religion was both reinforced and undercut, medicine progressed, art changed and the continent awash with guilt and memorialisation. With Miri Rubin, Professor of Medieval and Early Modern History at Queen Mary, University of London; Samuel Cohn, Professor of Medieval History at the University of Glasgow; Paul Binski, Professor of the History of Medieval Art at Gonville and Caius College, University of Cambridge

Melvyn Bragg and guests discuss the Library at Nineveh, a treasure house of Assyrian ideas from the 7th Century BC. In 1849 a young English adventurer called Henry Layard started digging into a small hill on the banks of the River Tigris in Northern Iraq. Underneath it he found the ancient city of Nineveh. Layard unearthed extraordinary things - wonderful carved reliefs, ancient palace rooms and great statues of winged bulls. He also found a collection of clay tablets, broken up, jumbled around and sitting on the floor of a toilet. It was the remnants of a library and although Layard didn’t know it at the time, it was one of the greatest archaeological finds ever made.Conceived to house the sum of all human knowledge the library was built in the 7th century BC as the grand Assyrian Empire entered its last years. The clay tablets have proved to be a window into all aspects of Assyrian life, its literature, politics, religion and medicine – practises that are both deeply alien to us and alluringly familiar. With Eleanor Robson, Senior Lecturer at Cambridge University and Vice-Chair of the British Institute for the Study of Iraq; Karen Radner, Lecturer in the Ancient Near Eastern History at University College London; Andrew George, Professor of Babylonian at the School of Oriental and African Studies at the University of London

Melvyn Bragg and guests discuss the history of ideas about the human brain. Since time immemorial people have puzzled over the brain and its functions. In the 5th century BC the Greek physician Hippocrates confidently asserted:“Men ought to know that from the brain and from the brain only arise our pleasures, joys, laughter and jests, as well as our sorrows, pains, grieves and tears.” This might suggest that people have never doubted the importance of the brain, but for Aristotle the heart was the ruler of the body and the seat of the soul. Only in the 17th century, with new scientific advances, did the true importance of the brain begin to be appreciated. In 1669 the Danish anatomist, Nicolaus Steno, still lamented that, “the brain, the masterpiece of creation, is almost unknown to us.”How far have our perceptions of how the brain works and what it symbolises changed over the centuries? And, in amongst the matter or our little grey cells, are we still searching for our souls? With Vivian Nutton, Professor of the History of Medicine at University College London; Jonathan Sawday, Professor of English Studies at the University of Strathclyde; Marina Wallace, Professor at the University of the Arts, London, Central St Martin’s College of Art and Design

Melvyn Bragg and guests discuss the enclosure movement of the 18th and 19th centuries. In the early 19th century, the Northamptonshire poet John Clare took a good look at the countryside and didn’t like what he saw. He wrote: "Fence meeting fence in owners little boundsOf field and meadow, large as garden-grounds,In little parcels little minds to please,With men and flocks imprisoned, ill at ease."Enclosure means literally enclosing a field with a fence or a hedge to prevent others using it. This seemingly innocuous act triggered a revolution in land holding that dispossessed many, enriched a few but helped make the agricultural and industrial revolutions possible. It saw the dominance of private property as the model of ownership, as against the collective rights of previous generations. For some Enclosure underpinned the economic and agricultural development of Modern Britain. But it has also been a cause celebre for the political left ever since Karl Marx argued that enclosures created the industrialised working class and ushered in the capitalist society. What really happened during the era of 18th and 19th century enclosures? Who gained, who lost and what role did Enclosures play in the agricultural and industrial transformation of this country? With Rosemary Sweet, Director of the Centre for Urban History at the University of Leicester; Murray Pittock, Bradley Professor of English Literature at the University of Glasgow; Mark Overton, Professor of Economic and Social History at the University of Exeter.

Melvyn Bragg and guests discuss Materialism in Philosophy – the idea that matter and the interactions between matter account for all that exists and all that happens. We trace the descent of materialism from the ancient Greek philosophers Democritus and Epicurus, to its powerful and controversial flowering in the 17th, 18th and 19th centuries as an attack on religion. It’s provocative stuff even today and certainly was in 1770 when Baron D’Holbach published his book The System of Nature. He wrote: "If we go back to the beginning we shall find that ignorance and fear created the gods; that fancy, enthusiasm, or deceit adorned or disfigured them; that weakness worships them; that credulity preserves them, and that custom, respect and tyranny support them."Materialism was considered so dangerous that every copy of the Baron’s book was condemned to be burnt. Despite this, or perhaps because of it, materialism dominates much of our understanding of the world today. Associated with science and atheism, Materialism has influenced many forms of contemporary human thought from the process of history to the diagnosis of disease and boasts a cast list of devotees including Pierre Gassandi, Thomas Hobbes, the Marquis de Sade and Karl Marx. But what does materialism really mean, how has it developed over time and can we still have free will if we are living in a materialist world? With Anthony Grayling, Professor of Philosophy at Birkbeck College, University of London; Caroline Warman, Fellow of Jesus College, Oxford; Anthony O’Hear, Professor of Philosophy at the University of Buckingham

Melvyn Bragg and guests discuss the poet W.B. Yeats and Irish politics. Yeats lived through a period of great change in Ireland from the collapse of the home rule bill through to the Easter Rising of 1916 and the partitioning of the country. In May 1916, 15 men were shot by the British government. They were the leaders of the Easter Rising – a doomed attempt to overthrow British rule in Ireland - and they were commemorated by W.B. Yeats in a poem called Easter 1916. It ends with the following lines: MacDonagh and MacBrideAnd Connolly and PearseNow and in time to be,Wherever green is worn,Are changed, changed utterly:A terrible beauty is born.Yeats lived through decades of turbulence in Ireland. He saw the suspension of home rule, civil war and the division of the country, but how did the politics of the age imprint themselves on his poetry, what was the nature of Yeats’ own nationalism, and what did he mean by that most famous of phrases ‘a terrible beauty is born’?With Roy Foster, Carroll Professor of Irish History at Oxford University and Fellow of Hertford College, Oxford; Fran Brearton, Reader in English at Queen’s University, Belfast and Assistant Director of the Seamus Heaney Centre for Poetry; Warwick Gould, Director of the Institute of English Studies in the School of Advanced Study, University of London

Melvyn Bragg and guests discuss ‘the Norman Yoke’ – the idea that the Battle of Hastings sparked years of cruel oppression for the Anglo Saxons by a Norman ruling class. ‘Norman saw on English oak,On English neck a Norman yoke;Norman spoon in English dish,And England ruled as Normans wish.’Taken from Sir Walter Scott’s novel ‘Ivanhoe’, these words encapsulate the idea of ‘the Norman Yoke’ – that the Battle of Hastings sparked the cruel oppression of Anglo-Saxon liberties by a foreign ruling class. Certainly, William the Conqueror proclaimed his power in great castles and cathedrals, turned the church upside down and even changed the colour of scribal ink. But was it really such a terrible time for the Anglo Saxons or was the idea of beastly Norman oppressors and noble Saxon sufferers invented later to shore up the idea of Englishness? With Sarah Foot, Regius Professor of Ecclesiastical History at Christ Church, Oxford; Richard Gameson, Professor in the Department of History at Durham University; Matthew Strickland, Professor of Medieval History at the University of Glasgow.

Melvyn Bragg and guests discuss Newton’s Laws of Motion. In 1687 Isaac Newton attempted to explain the movements of everything in the universe, from a pea rolling on a plate to the position of the planets. It was a brilliant, vaultingly ambitious and fiendishly complex task; it took him three sentences. These are the three laws of motion with which Newton founded the discipline of classical mechanics and conjoined a series of concepts - inertia, acceleration, force, momentum and mass - by which we still describe the movement of things today. Newton’s laws have been refined over the years – most famously by Einstein - but they were still good enough, 282 years after they were published, to put Neil Armstrong on the Moon.

Melvyn Bragg and guests discuss Henry VIII and the Dissolution of the Monasteries. Was Henry’s decision to destroy monastic culture in this country a tyrannical act of grand larceny or the pious destruction of a corrupt institution? When he was an old man, Michael Sherbrook remembered the momentous events of his youth: “All things of price were either spoiled, plucked away or defaced to the uttermost…it seemed that every person bent himself to filch and spoil what he could. Nothing was spared but the ox-houses and swincotes…” He was talking about the destruction of Roche Abbey, but it could have been Lewes or Fountains, Glastonbury, Tintern or Walsingham, names that haunt the religious past as their ruins haunt the landscape. These were the monasteries, suddenly and for many shockingly, destroyed during the reign of Henry VIII.The conflict was played out with a mix of violence, heroism, political manoeuvring and genuine theological disputation. But what was lost in terms of architecture, painting, treasure and in the religious habits of the monasteries themselves and of the common people who lived with them?With Diarmaid MacCulloch, Professor of the History of the Church at Oxford University; Diane Purkiss, Fellow and Tutor at Keble College, Oxford; George Bernard, Professor of Early Modern History at the University of Southampton

Melvyn Bragg and guests discuss the rich and radical ideas of Soren Kierkegaard, often called the father of Existentialism.In 1840 a young Danish girl called Regine Olsen got engaged to her sweetheart – a modish and clever young man called Søren Kierkegaard. The two were deeply in love but soon the husband to be began to have doubts. He worried that he couldn’t make Regine happy and stay true to himself and his dreams of philosophy. It was a terrible dilemma, but Kierkegaard broke off the engagement – a decision from which neither he nor his fiancée fully recovered. This unhappy episode has become emblematic of the life and thought of Søren Kierkegaard - a philosopher who confronted the painful choices in life and who understood the darker modes of human existence. Yet Kierkegaard is much more than the gloomy Dane of reputation. A thinker of wit and elegance, his ability to live with paradox and his desire to think about individuals as free have given him great purchase in the modern world and he is known as the father of Existentialism.With Jonathan Rée, Visiting Professor at Roehampton University and the Royal College of Art; Clare Carlisle, Lecturer in Philosophy at the University of Liverpool; John Lippitt, Professor of Ethics and Philosophy of Religion at the University of Hertfordshire.

Melvyn Bragg and guests discuss the Greek myths from Achilles to Zeus. Are you a touch narcissistic? Do you have the body of an Adonis? Are you willing to undertake Herculean tasks or Promethean ventures? Perhaps you have an Oedipus complex? If you answer to any or perhaps all of these you owe something to the Greek myths, a collection of weird and wonderful stories that, like Penelope’s shroud or the needlework of Arachne, were constantly woven and unpicked across centuries of Greek and Roman civilisation. The myths have a cast of thousands including mighty Zeus, Jason and the Argonauts, wily Odysseus, beautiful Aphrodite and Cerberus, the three-headed dog. They are funny, shocking, quirky and epic and have retained their power and their wisdom from the ancient world to the modern. With Nick Lowe, Senior Lecturer in Classics at Royal Holloway, University of London; Richard Buxton, Professor of Greek Language and Literature at the University of Bristol; Mary Beard, Professor of Classics at Cambridge University

Melvyn Bragg and guests discuss the 19th century mathematician Ada Lovelace. Deep in the heart of the Pentagon is a network of computers. They control the US military, the most powerful army on the planet, but they are controlled by a programming language called Ada. It’s named after Ada Lovelace, the allegedly hard drinking 19th century mathematician and daughter of Lord Byron. In her work with Charles Babbage on a steam driven calculating machine called the Difference Engine, Ada understood, perhaps before anyone else, what a computer might truly be. As such the Difference Engine is the spiritual ancestor of the modern computer.Ada Lovelace has been called many things - the first computer programmer and a prophet of the computer age – but most poetically perhaps by Babbage himself as an ‘enchantress of numbers’.With Patricia Fara, Senior Tutor at Clare College, Cambridge; Doron Swade, Visiting Professor in the History of Computing at Portsmouth University; John Fuegi, Visiting Professor in Biography at Kingston University.

Melvyn Bragg and guests discuss King Lear. Around the turn of 1606, a group of London theatre-goers braved the plague to take in a new play by the well-known impresario, Mr William Shakespeare. Packed into the Globe Theatre, they were treated to a tale of violence, hatred and betrayal so upsetting that it thereafter languished among Shakespeare’s less popular plays.The story of Lear – of a man who divides up his property and loses the love of a daughter - is an ancient and ultimately happy one. But in the hands of William Shakespeare it became a shocking and violent vision of a broken family in a godless universe. So shocking that after the playwright’s death it was shunned and rewritten with a happy ending. Only in the 19th and 20th centuries did Shakespeare’s bleak, experimental and disorientating drama attain the status it has now. But why did Shakespeare take a story from the deep history of Britain and make it so shockingly his own and when, from the Civil War to the Second World War, did this powerful and confusing tragedy emerge as Shakespeare’s greatest? With Jonathan Bate, Professor of English Literature at the University of Warwick; Katherine Duncan-Jones, Tutorial Fellow in English at Somerville College, Oxford; Catherine Belsey, Research Professor in English at the University of Wales, Swansea

Melvyn Bragg and guests will be leaving the studio, the planet and indeed, the universe to take a tour of the Multiverse. If you look up the word ‘universe’ in the Oxford English Dictionary you will find the following definition: “The whole of created or existing things regarded collectively; all things (including the earth, the heavens, and all the phenomena of space) considered as constituting a systematic whole.” That sounds fairly comprehensive as a description of everything, but for an increasing number of physicists and cosmologists the universe is not enough. They talk of a multiverse – literally many universes – to explain aspects of their theory, the character of the universe and the riddle of our existence within it. Indeed, compared to the scope and complexity of the multiverse, the whole of our known reality may be as a speck of sand upon a beach.The idea of a multiverse is still controversial, some argue that it isn’t even science, because it is based on an idea that we may never be able to prove or even see. But what might a multiverse be like, why are physicists and cosmologists increasingly interested in it and is it really scientific to discuss the existence of universes we may never know anything With Martin Rees, President of the Royal Society and Professor of Cosmology and Astrophysics at the University of Cambridge; Fay Dowker, Reader in Theoretical Physics at Imperial College; Bernard Carr, Professor of Mathematics and Astronomy at Queen Mary, University of London

Melvyn Bragg and guests discuss the Statue of Liberty."Give me your tired, your poor, your huddled masses yearning to breathe free”. With these words, inscribed inside her pedestal, the Statue of Liberty has welcomed immigrants to America since 1903. But the Statue of Liberty is herself an immigrant, born in Paris she was shipped across the Atlantic in 214 separate crates, a present to the Americans from the French. She is a token of friendship forged in the fire of twin revolutions, finessed by thinkers like Alexis de Tocqueville and expressed in the shared language of liberty. But why was this colossal statue built, who built it and what did liberty mean to the Frenchmen who created her and the Americans who received her?With Robert Gildea, Professor of Modern History at Oxford University; Kathleen Burk, Professor of Modern Contemporary History at University College London; John Keane, Professor of Politics at the University of Westminster

Melvyn Bragg and guests discuss the Social Contract and ask a foundational question of political philosophy – by what authority does a government govern? “Man was born free and he is everywhere in chains”. So begins Jean Jacques Rousseau’s great work on the Social Contract. Rousseau was trying to understand why a man would give up his natural freedoms and bind himself to the rule of a prince or a government. But the idea of the social contract - that political authority is held through a contract with those to be ruled - began before Rousseau with the work of John Locke, Hugo Grotius and even Plato. We explore how an idea that burgeoned among the 17th century upheavals of the English civil war and then withered in the face of modern capitalist society still influences our attitude to government today. With Melissa Lane, Senior University Lecturer in History at Cambridge University; Susan James, Professor of Philosophy at Birkbeck College, University of London; Karen O’Brien, Professor of English Literature at the University of Warwick.

Melvyn Bragg and guests discuss the coterie of brilliant thinkers gathered in 16th century Prague by the melancholic emperor Rudolph II. In 1606 the Archdukes of Vienna declared: “His majesty is interested only in wizards, alchemists, Kabbalists and the like, sparing no expense to find all kinds of treasures, learn secrets and use scandalous ways of harming his enemies…He also has a whole library of magic books. He strives all the time to eliminate God completely so that he may in future serve a different master.”The subject of this coruscating attack was the Holy Roman Emperor, Rudolf II, and his court at Prague. Rudolph had turned Prague into a collector’s cabinet for the wonders and curiosities of the age – the great paintings of Northern Italy were carried to him over the Alps, intricate automatons constructed to serve drinks, maps and models of the heavens were unwound and engineered as the magnificent city of Prague itself was rebuilt in the image of its dark and thoughtful patron in chief. But Rudolf’s greatest possessions were people - the astronomers Johannes Kepler and Tycho Brahe, the magus John Dee and the philosopher Giordano Bruno had all found their way to his city. Far from the devilish inquisitor of the archdukes’ imaginations, Rudolf patronised a powerhouse of Renaissance ideas. With Peter Forshaw, Postdoctoral Fellow at Birkbeck, University of London and an Honorary Fellow of the University of Exeter; Howard Hotson, Lecturer in Modern History at the University of Oxford; Adam Mosley, Lecturer in the Department of History at the University of Wales, Swansea.

Melvyn Bragg and guests discuss how the science of plate tectonics revolutionised our understanding of the planet on which we live. America is getting further away from Europe. This is not a political statement but a geological fact. Just as the Pacific is getting smaller, the Red Sea bigger, the Himalayas are still going up and one day the Horn of Africa will be a large island. This is the theory of plate tectonics, a revolutionary idea in 20th century geology that claimed the continents of Earth were dancing to the music of deep time. A dance of incredible slowness, yet powerful enough to throw up the mountains and pour away the oceans.Plate tectonics, the idea that the earth’s surface moved on a carpet of molten magma, constituted a genuine scientific revolution in geology. It explained why mountains appeared and why earth quakes occurred; it explained the curious distribution of fossils across the globe and finally solved the age old conundrum of why continents such as Africa and South America appeared to fit together like a giant jigsaw puzzle. Plate tectonics has made geologists, and many more besides, profoundly re-think what the Earth was, how it worked and how it related to all the things in it. With Richard Corfield, Visiting Senior Lecturer in Earth Sciences at the Open University; Joe Cann, Senior Fellow in the School of Earth and Environment at the University of Leeds; Lynne Frostick, Director of the Hull Environment Research Institute and Professor of Physical Geography at the University of Hull

Melvyn Bragg and guests will be delving into the world of medieval legend in pursuit of the powerful and enigmatic Fisher King. In the world of medieval romance there are many weird and wonderful creatures – there are golden dragons and green knights, sinister enchantresses and tragic kings, strange magicians and spears that bleed and talk. And yet, in all this panoply of wonder, few figures are more mysterious than the Fisher King.Blighted by a wound that will not heal and entrusted as the keeper of the Holy; the Fisher King is also a version of Christ, a symbol of sexual anxiety and a metaphor for the decay of societies and civilisations. The Fisher King is a complex and poetic figure and has meant many things to many people. From the age of chivalry to that of psychoanalysis, his mythic even archetypal power has influenced writers from Chrétien de Troyes in the 12th century to TS Eliot in the 20th. With Carolyne Larrington, Tutor in Medieval English at St John’s College, Oxford; Stephen Knight, Distinguished Research Professor in English Literature at Cardiff University; Juliette Wood, Associate Lecturer in the Department of Welsh, Cardiff University and Director of the Folklore Society

Melvyn Bragg and guests discuss the Charge of the Light - an event of no military significance that has become iconic in the British historical imagination. On November 14th 1854 The Times newspaper reported on a minor cavalry skirmish in the Crimean War: “They swept proudly past, glittering in the morning sun in all the pride and splendour of war... At the distance of 1200 yards the whole line of the enemy belched forth, from thirty iron mouths, a flood of smoke and flame through which hissed the deadly balls. Their flight was marked by instant gaps in our ranks, by dead men and horses, by steeds flying wounded or riderless across the plain”.This is the debacle of the Charge of the Light Brigade, which made little difference to the Crimean War yet has become deeply embedded in British culture. It helped to provoke the resignation of a Prime Minister and it profoundly changed British attitudes to war and to the soldiers who fought in them. It also brought censorship to bear on previously uncensored war reporting and inspired Alfred, Lord Tennyson to sit down and write “All in the Valley of Death rode the six hundred”.With Mike Broers, Lecturer in Modern History at the University of Oxford and a Fellow of Lady Margaret Hall; Trudi Tate, Fellow of Clare Hall, Cambridge; Saul David, Visiting Professor of Military History at the University of Hull

Melvyn Bragg and guests discuss the Algerian-French writer and Existentialist philosopher Albert Camus. Shortly after the new year of 1960, a powerful sports car crashed in the French town of Villeblevin in Burgundy, killing two of its occupants. One was the publisher Michel Gallimard; the other was the writer Albert Camus. In Camus’ pocket was an unused train ticket and in the boot of the car his unfinished autobiography The First Man. Camus was 46. Born in Algeria in 1913, Camus became a working class hero and icon of the French Resistance. His friendship with Sartre has been well documented, as has their falling out; and although Camus has been dubbed both an Absurdist and Existentialist philosopher, he denied he was even a philosopher at all, preferring to think of himself as a writer who expressed the realities of human existence. Awarded the Nobel Prize for Literature in 1957, Camus’ legacy is a rich one, as an author of plays, novels and essays, and as a political thinker who desperately sought a peaceful solution to the War for Independence in his native Algeria. With Peter Dunwoodie, Professor of French Literature at Goldsmiths, University of London; David Walker, Professor of French at the University of Sheffield; Christina Howells, Professor of French at Wadham College, University of Oxford.

Melvyn Bragg and guests discuss the Nicene Creed which established the Divinity of Christ. "We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible. And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds." Thus begins the Nicene Creed, a statement of essential faith spoken for over 1600 years in Christian Churches - Catholic, Orthodox and Protestant. But what has become a universal statement was written for a very particular purpose - to defeat a 4th century theological heresy called Arianism and to establish that Jesus Christ was, indeed, God. The story of the Creed is in many ways the story of early Christianity – of delicate theology and robust politics. It changed the Church and it changed the Roman Empire, but that it has lasted for nearly 2000 years would seem extraordinary to those who created it. With Martin Palmer, Director of the International Consultancy on Religion, Education and Culture; Caroline Humfress, Reader in History at Birkbeck College, University of London; Andrew Louth, Professor of Patristic and Byzantine Studies at the University of Durham.

Melvyn Bragg and guests talk about blood, black bile, yellow bile and phlegm. These are the four humours, a theory of disease and health that is among the most influential ideas aver conceived. According to an 11th century Arabic book called the Almanac of Health, an old man went to the doctor complaining of a frigid complexion and stiffness in winter. The doctor, after examining his condition, prescribed a rooster. Being a hot and dry bird it was the perfect tonic for a cold and rheumatic old man. This is medicine by the four humours. The idea that the body is a concoction of these four essential juices is one of the oldest on record. From the Ancient Greeks to the 19th century it explained disease, psychology, habit and personality. When we describe people as being choleric, sanguine or melancholic we are still using the language of the humours today. It also explains why, in the long and convoluted history of medical practice, pigeon livers were an aphrodisiac, blood letting was a form of heroism (and best done in spring) and why you really could be frightened to death. The theory was dismantled from the 17th century but in its belief that the mind and body are intimately connected and that health requires equilibrium the humours retain an influence to this dayWith David Wootton, Anniversary Professor of History at the University of York; Vivian Nutton, Professor of the History of Medicine at University College London; Noga Arikha, Visiting Fellow at the Institut Jean-Nicod in Paris

Melvyn Bragg and guests discuss the Sassanian Empire. Founded around 226 AD, in Persia, the Sassanian Empire lasted over 400 years as a grand imperial rival to Rome. In modern day Iran, just down the road from the ancient Persian capital of Persepolis, there is a picture carved into a rock. It depicts a king, triumphant on horseback, facing two defeated enemies. This is no pair of petty princes, they are Roman Emperors - Philip and Valerian - and the king towering above them is Shapur I of the Sassanian Empire. So complete was his victory that Shapur is reputed to have used Valerian as a footstool when mounting his horse. This super-power traded goods from Constantinople to Beijing, handed regular defeats to the Roman army and only fell to the Islamic conquests of the 7th century. It still influences Persian identity to this day. But what was the culture and the literature of the empire, its structure and organisation? And what was its role in the great geopolitical game played out between the decaying empires in late antiquity?With Hugh Kennedy, Professor of Arabic in the Faculty of Languages and Cultures at the School of Oriental and African Studies; Vesta Sarkhosh Curtis, Curator of Iranian and Islamic Coins in the British Museum; James Howard-Johnston, University Lecturer in Byzantine Studies at the University of Oxford.
