In Our Time

Melvyn Bragg and guests discuss the Oxford Movement in the Church of England in the 19th century. Cardinal John Henry Newman is perhaps the most significant Christian theologian of the nineteenth century. He began as an evangelical, becoming a High Anglican before converting to Roman Catholicism in 1845. His is the story of the diversity of Victorian religious life. But his path also marks the waning of the ideas of Protestant nationhood at the close of the eighteenth century and the reaffirmation of the Catholic tradition at the turn of the twentieth century. For over a decade, between 1833 and 1845, Newman and his fellow travellers, the Oxford Movement, argued that the Church of England was a holy Catholic and Apostolic Church. They sought to assert the Catholic nature of their Church just as secularism, liberalism, non-conformism, and even Roman Catholicism, seemed to threaten her. They published tracts, preached and brought their social mission to some of the poorest urban parishes. Why between 1833 and 1845 was the voice of reaction such a loud one? What was the Oxford Movement and what motivated them? How did they present their ideas to the Anglican clergy at large and what did the clergy make of them? And why did they leave such a powerful legacy for the Church of England, its character and its churches? With Sheridan Gilley, Emeritus Reader in Theology at the University of Durham; Frances Knight, Senior Lecturer in Church History at the University of Wales, Lampeter; Simon Skinner, Fellow and Tutor in History at Balliol College, Oxford.

Melvyn Bragg and guests discuss Johann Wolfgang Goethe, the great German polymath. 'I had the great advantage of being born at a time that was ripe for earth-shaking events which continued throughout my long life, so that I witnessed the Seven Years War...the French Revolution, and the whole Napoleonic era down to the defeat of the hero and what followed after him. As a result I have attained completely different insights and conclusions than will ever be possible for people who are born now...' Goethe's friend Johann Peter Eckermann recorded these remarks made by the great writer at the end of his life in a series of published recollections. Goethe's life was indeed remarkable. At the age of twenty-five he was author of the first German international best-seller The Sorrows of Young Werther. A year later, he was invited by the Grand Duke to join him at the Imperial Court as Privy Councillor where he oversaw commissions on war, roads and tax. He rode to war with the Prussian Army against the French and embarked on a remarkable creative friendship with Schiller which saw the establishment of a new form of German theatre. What made Goethe the dominant cultural icon of his time and after? What links were there between his interest in politics and the arts? Why did he support Napoleon despite the French invasion of Weimar? How did his relationships with women define his work? And how was he able to transform the status of the German language? With Tim Blanning, Professor of Modern European History at the University of Cambridge; Sarah Colvin, Professor of German at the University of Edinburgh; W. Daniel Wilson, Professor of German at Royal Holloway, University of London.

Melvyn Bragg and guests discuss the Holy Roman Emperor Charlemagne and the Carolingian Renaissance. In 800 AD on Christmas Day in Rome, Pope Leo III proclaimed Charlemagne Emperor. According to the Frankish historian Einhard, Charlemagne would never have set foot in St Peter's that day if he had known that the Pope intended to crown him. But Charlemagne accepted his coronation with magnanimity. Regarded as the first of the Holy Roman Emperors, Charlemagne became a touchstone for legitimacy until the institution was brought to an end by Napoleon in 1806. A Frankish King who held more territory in Western Europe than any man since the Roman Emperor, Charlemagne's lands extended from the Atlantic to Vienna and from Northern Germany to Rome. His reign marked a period of enormous cultural and literary achievement. But at its foundation lay conquest, conversion at the point of a sword and a form of Christianity that was obsessed with sin, discipline and correction. How did Charlemagne become the most powerful man in Western Europe and how did he finance his conquests? Why was he able to draw Europe's most impressive scholars to his court? How successful was he in his quest to reform his church and educate the clergy? And can the Carolingian period really be called a Renaissance? With Matthew Innes, Professor of History at Birkbeck, University of London; Julia Smith, Edwards Professor of Medieval History at Glasgow University; Mary Garrison, Lecturer in History at the University of York

Melvyn Bragg and guests discuss the formation of the Royal Society. In the 17th century the natural philosopher Francis Bacon heralded the new age of science. The frontispiece to his 1620 edition of the Instauratio Magna depicted a galleon travelling between the metaphorical Pillars of Hercules thought to lie at the Strait of Gibraltar and believed to mark the end of the known world. The image encapsulated Bacon's desire to sail beyond the limits set by Aristotle and the curriculum of the Ancient universities towards the new continent of science. Bacon imagined practical scientists engaged in a collaborative effort to expand knowledge of the natural world. But it was not until the turbulence of the Civil War and Commonwealth years had passed that such a group of scientists would gather together in London for this purpose, and form the Royal Society. Amongst its members were Robert Boyle, Robert Hooke, Christopher Wren and Isaac Newton, who explicitly rejected dogma and insisted on practical experimentation and observation. How was the Royal Society formed against a backdrop of religious and political strife? What was it about the way this group of men worked that allowed each individual to flourish in his own field? How successful was the Royal Society in disseminating the benefits of experimental science and what is its enduring legacy? With Stephen Pumfrey, Senior Lecturer in the History of Science at the University of Lancaster; Lisa Jardine, Professor of Renaissance Studies at Queen Mary, University of London; Michael Hunter, Professor of History at Birkbeck, University of London.

Melvyn Bragg and guests discuss Miguel de Cervantes’ 17th century novel, Don Quixote. Published four hundred years ago in Madrid, the book was an immediate success and recognised as one of the classic texts of Western Literature, revered by writers such as Sterne, Goethe, Flaubert, Dostoevsky, Kafka and Melville. Don Quixote tells the story of an unlikely hero - an impoverished country gentleman who goes mad from reading too much and decides to put the world to rights by becoming a knight errant. And so the Knight of La Mancha tilting at windmills with his portly squire astride a donkey is one of the most enduring images in the popular imagination but the simple comedy of the affair belies the fantastically complex, beguiling and sophisticated story on which it is based. As Don Quixote's delusional chivalric ideals bump up against the humdrum of reality and the views of his more earth-bound companion, Sancho Panza.So how has the book endured over the centuries? What was the relationship between Cervantes' work and the world of 17th century Spain in which he lived? In what ways was Don Quixote an interpretation of the age which hitherto had not been articulated? And can it live up to the claim that it was the first European novel?With Barry Ife, Cervantes Professor Emeritus at King's College London; Edwin Williamson, Professor of Spanish Studies at the University of Oxford; Jane Whetnall, Senior Lecturer in Hispanic Studies at Queen Mary, University of London.

Melvyn Bragg and guests discuss negative numbers, a history of mystery and suspicion. In 1759 the British mathematician Francis Maseres wrote that negative numbers "darken the very whole doctrines of the equations and make dark of the things which are in their nature excessively obvious and simple". Because of their dark and mysterious nature, Maseres concluded that negative numbers did not exist, as did his contemporary, William Friend. However, other mathematicians were braver. They took a leap into the unknown and decided that negative numbers could be used during calculations, as long as they had disappeared upon reaching the solution. The history of negative numbers is one of stops and starts. The trailblazers were the Chinese who by 100 BC were able to solve simultaneous equations involving negative numbers. The Ancient Greeks rejected negative numbers as absurd, by 600 AD, the Indians had written the rules for the multiplication of negative numbers and 400 years later, Arabic mathematicians realised the importance of negative debt. But it wasn't until the Renaissance that European mathematicians finally began to accept and use these perplexing numbers. Why were negative numbers considered with such suspicion? Why were they such an abstract concept? And how did they finally get accepted? With Ian Stewart , Professor of Mathematics at the University of Warwick; Colva Roney-Dougal , Lecturer in Pure Mathematics at the University of St Andrews; Raymond Flood , Lecturer in Computing Studies and Mathematics at Kellogg College, Oxford.

Melvyn Bragg and guests discuss the concept of friendship. In Greek and Roman times, friendship was thought of as being an essential constituent of both a good society and a good life; a good society because it lay at the heart of participative civic democracy; a good life because it nurtured wisdom and happiness. It is this period which gives us the texts on friendship which, to this day, are arguably the most important of their kind. Amongst their authors is Aristotle, who engaged in one of the great philosophical discussions on the subject. For Aristotle, friendship could fall into three categories: it could be based on utility, pleasure or goodness. In its latter state, Aristotle described it as being 'a single soul dwelling in two bodies'. So how did the Ancients establish the parameters of the true nature of friendship in the literature and philosophy that followed? How have different forms of friendship helped or hindered creativity and intellectual pursuit? What has been the apparent relationship between friendship and power? And what of the darker aspects of friendship - jealousy, envy and exploitation? With Angie Hobbs, Lecturer in Philosophy at the University of Warwick; Mark Vernon, Visiting Lecturer in Philosophy at Syracuse University and London Metropolitan University; John Mullan, Professor of English at University College London.

Melvyn Bragg and guests discuss Catherine the Great. In Moscow's Tretyakov Gallery hangs perhaps the most well-known picture of Russia's most well-known ruler. Dimitri Levitsky's 1780 'Portrait of Catherine the Great in the Justice Temple' depicts Catherine in the temple burning poppies at an altar, symbolising her sacrifice of self-interest for Russia. Law books and the scales of justice are at her feet, highlighting her respectful promotion of the rule of law. But menacingly, in the background an eagle crouches, suggesting the means to use brutal power where necessary. For an obscure, small-town German princess Catharine’s ambition was large - the transformation of semi-barbaric Russia into a model of the ideals of the French 18th century Enlightenment. How far was Catherine able to lead her country into full participation in the political and cultural life of Europe? Was she able to liberate the serfs? And should she be remembered as Russia's most civilised ruler or a megalomaniacal despot? With Janet Hartley, Professor of International History at the London School of Economics; Simon Dixon, Professor of Modern History at the University of Leeds; Tony Lentin, Professor of History at the Open University.

Melvyn Bragg and guests discuss the story of human evolution, which stretches back over six million years. It is not the story of one species but of several diverse species, some of whom walked the Earth at the same time. From the earliest hominids to the early Homo sapiens, there was nothing inevitable about the course of human evolution. But what conditions created the opportunity for diverse human species to thrive? What environmental factors led to the survival of one human species, but contributed to the extinction of so many others? What can the fossil record and the science of genetics tell us about our ancestors? How does the brain make modern man so unique in the natural world? With Steve Jones, Professor of Genetics in the Galton Laboratory at University College London; Fred Spoor, Professor of Evolutionary Anatomy at University College London; Margaret Clegg, Honorary Research Fellow in the Department of Biological Anthropology at University College London.

Melvyn Bragg and guests discuss Geoffrey Chaucer, often called the father of English literature."In Southwark at the Tabard as I lay Redy to wenden on my pilgrymage To Canterbury with ful devout corage, At nyght was come into that hostelrye Wel nyne and twenty in a compaignye Of sundry folk, by aventure yfalle In felaweshipe, and pilgrims were they alle, That toward Canterbury wolden ryde." Geoffrey Chaucer immortalised the medieval pilgrimage and the diversity of 14th century English society in his Canterbury Tales. As each pilgrim takes his, or her, turn to tell their tale on the road to Canterbury, Chaucer brings to life the voices of a knight, a miller, a Wife of Bath and many more besides. Chaucer was born the son of a London vintner, yet rose to high office in the court of Richard II. He travelled throughout France and Italy where he came into contact with the works of Dante, Boccaccio, Machaut and Froissart. He translated Boethius, wrote dream poetry, a defence of women and composed the tragic masterpiece Troilus and Criseyde. As well as the father of English literature, Chaucer was also a philosopher, bureaucrat, courtier and diplomat.So what do we know of Chaucer? How did he introduce the themes of continental writing to an English speaking audience? And why does his poetry still seem to speak so directly to us today? With Carolyne Larrington, Tutor in Medieval English at St John's College, Oxford; Helen Cooper, Professor of Medieval and Renaissance English at the University of Cambridge; Ardis Butterfield, Reader in English at University College London.

Melvyn Bragg and guests discuss the Abbasid Caliphs, dynastic rulers of the Islamic world from the mid eighth to the tenth century. They headed a Muslim empire that extended from Tunisia through Egypt, Syria, Arabia, and Persia to Uzbekistan and the frontiers of India. But unlike previous conquerors, the Abbasid Caliphs presided over a multicultural empire where conversion was a relatively peaceful business. As Vikings raided the shores of Britain, the Abbasids were developing sophisticated systems of government, administration and court etiquette. Their era saw the flowering of Arabic philosophy, mathematics and Persian literature. The Abbasids were responsible for patronising the translation of Classical Greek texts and transmitting them back to a Europe emerging from the Dark Ages. So who were the Abbasid Caliphs and how did they come to power? What was their cultural significance? What factors can account for their decline and fall? And why do they represent a Golden Age of Islamic civilisation? With Hugh Kennedy, Professor of History at the University of St Andrews; Robert Irwin, Senior Research Associate 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.

Melvyn Bragg and guests discuss 17th century print culture."Away ungodly Vulgars, far away, Fly ye profane, that dare not view the day, Nor speak to men but shadows, nor would hear Of any news, but what seditious were, Hateful and harmful and ever to the best, Whispering their scandals ... " In 1614 the poet and playwright George Chapman poured scorn on the popular appetite for printed news. However, his initial scorn did not stop him from turning his pen to satisfy the public's new found appetite for scandal. From the advent of the printing press the number of books printed each year steadily increased, and so did literacy rates. With a growing and socially diverse readership appearing over the sixteenth and seventeenth centuries, printed texts reflected controversy in every area of politics, society and religion. In the advent of the Civil War, print was used as the ideological battleground by the competing forces of Crown and Parliament. What sorts of printed texts were being produced? How widespread was literacy and who were the new consumers of print? Did print affect social change? And what role did print play in the momentous English Civil War? With Kevin Sharpe, Professor of Renaissance Studies at Queen Mary, University of London; Ann Hughes, Professor of Early Modern History at the University of Keele; Joad Raymond, Professor of English Literature at the University of East Anglia.

Melvyn Bragg and guests discuss relativism, a philosophy of shifting sands. "Today, a particularly insidious obstacle to the task of educating is the massive presence in our society and culture of that relativism which, recognizing nothing as definitive, leaves as the ultimate criterion only the self with its desires. And under the semblance of freedom it becomes a prison for each one, for it separates people from one another, locking each person into his or her own 'ego'." Pope Benedict XVI, in a speech given in June 2005, showed that the issue of relativism is as contentious today as it was in Ancient Greece, when Plato took on the relativist stance of Protagoras and the sophists. Relativism is a school of philosophical thought which holds to the idea that there are no absolute truths. Instead, truth is situated within different frameworks of understanding that are governed by our history, culture and critical perspective. Why has relativism so radically divided scholars and moral custodians over the centuries? How have its supporters answered to criticisms that it is inherently unethical? And if there are universal standards such as human rights, how do relativists defend culturally specific practices such as honour killings or female infanticide? With Barry Smith, Senior Lecturer in Philosophy at Birkbeck College, University of London; Jonathan Rée, freelance philosopher who holds visiting professorships at the Royal College of Art and Roehampton University; Kathleen Lennon, Senior Lecturer in Philosophy at the University of Hull.

Melvyn Bragg and guests discuss prime numbers: 2, 3, 5, 7, 11, 13, 17 … This sequence of numbers goes on literally forever. Recently, a team of researchers in Missouri successfully calculated the highest prime number - it has 9.1 million digits. For nearly two and a half thousand years, since Euclid first described the prime numbers in his book Elements, mathematicians have struggled to write a rule to predict what comes next in the sequence. The Swiss mathematician Leonhard Euler feared that it is "a mystery into which the human mind will never penetrate." But others have been more hopeful... In the middle of the nineteenth century, the German mathematician Bernhard Riemann discovered a connection between prime numbers and a complex mathematical function called the 'zeta function'. Ever since, mathematicians have laboured to prove the existence of this connection and reveal the rules behind the elusive sequence. What exactly are prime numbers and what secrets might they unlock about our understanding of atoms? What are the rules that may govern the prime sequence? And is it possible that the person who proves Riemann's Hypothesis may bring about the collapse of the world financial system? With Marcus du Sautoy, Professor of Mathematics and Fellow of Wadham College at the University of Oxford; Robin Wilson, Professor of Pure Mathematics at the Open University and Gresham Professor of Geometry; Jackie Stedall, Junior Research Fellow in the History of Mathematics at Queen's College, Oxford.

Melvyn Bragg and guests discuss the importance of the oath in ancient Greece and Rome, The importance of oaths in the Classical world cannot be overstated. Kings, citizens, soldiers, litigants all swore oaths, inviting divine retribution if they proved false to their word. Oaths cemented peace treaties, they obliged the Athenian citizenry to protect their democracy, they guaranteed the loyalty of the Roman army to its Emperor and they underpinned the legal systems of Athens and Rome. And in Homer's epic poem, The Iliad, it is a broken oath to settle the dispute between Menelaus and Paris that leads the Greeks to storm Troy in pursuit of Helen. But how did the Classical world come to understand the oath? Why did oaths come to occupy such a central place in the political, social and legal life of the Athenian State? And what role did oath-making play in the expanding Roman Empire? With Alan Sommerstein , Professor of Greek at the University of Nottingham;Paul Cartledge , Professor of Greek History at the University of Cambridge; Mary Beard , Professor in Classics at the University of Cambridge

Melvyn Bragg and guests discuss the ‘Oresteia’, the seminal trilogy of tragedies by Aeschylus. The composer Richard Wagner recalled the visceral sensations of reading Aeschylus' great trilogy for the first time. "I could see the Oresteia with my mind's eye ... Nothing could equal the sublime emotion with which the Agamemnon inspired me; and to the last word of the Eumenides, I remained in an atmosphere so far removed from the present day that I have never since been really able to reconcile myself with modern literature." Aeschylus' audience were all familiar with the tale of one man's return home from the Trojan War. Homer's Odyssey recounted Odysseus' perilous journey home, the forceful ejection of the suitors from his household and his reunion with wife Penelope and son Telemachus. Aeschylus had a very different tale of homecoming to tell in his Oresteia. Agamemnon arrives home from Troy to a murderous welcome from a vengeful wife and a cycle of atrocities unfolds in his household. The Oresteia has inspired some of the greatest artists and thinkers of the modern world. From Richard Wagner and Friedrich Nietzsche to T.S. Eliot and Simone de Beauvoir – the ‘Oresteia’ has fired the modern imagination.Why did Aeschylus make the family the subject of his bloody revenge tragedy? How did his trilogy make a contribution to the development of Athenian legal institutions? And why has the Oresteia had such a powerful hold over the modern imagination? With Edith Hall, Professor of Greek Cultural History at Durham University; Simon Goldhill, Professor of Greek at the University of Cambridge; Tom Healy, Professor of Renaissance Studies at Birkbeck College, University of London.

Melvyn Bragg and guests discuss ideas of heaven and the afterlife. The great medieval theologian Thomas Aquinas wrote 'that in the end language can only be related to what is experienced here, and given that the hereafter is not here, we can only infer'. Aquinas encapsulated a great human conundrum that has preoccupied writers and thinkers since ancient times: what might heaven be like. And although human language is constrained by experience, this has not stopped an outpouring of artistic, theological and literary representations of heaven. In the early Middle Ages men ascended up a ladder to heaven. In his Divine Comedy, Dante divided heaven into ten layers encompassing the planets and the stars. And the 17th century writer John Bunyan saw the journey of the soul to heaven as a spiritual struggle in his autobiography, The Pilgrim's Progress. But what exactly is heaven and where is it? How does the Protestant conception of the afterlife differ from the Catholic conception? How does one achieve salvation and what do the saved do when they get there? And, if heaven is so interesting, why has western culture been so spellbound by hell? With Valery Rees, Renaissance scholar and senior member of the Language Department at the School of Economic Science; Martin Palmer, Theologian and Director of the International Consultancy on Religion, Education and Culture; John Carey, Emeritus Professor of English Literature at Oxford University.

Melvyn Bragg and guests discuss the Peterloo Massacre in 1819, a defining moment of its age. In 1819 Percy Bysshe Shelley wrote: 'I met Murder on the way He had a mask like Castlereagh Very smooth he looked, yet grim; Seven blood-hounds followed him: All were fat; and well they might Be in admirable plight, For one by one, and two by two, He tossed them human hearts to chew Which from his wide cloak he drew.' As Foreign Secretary, Castlereagh had successfully co-ordinated European opposition to Napoleon, but at home he had repressed the Reform movement, and popular opinion held him responsible for the Peterloo Massacre of peaceful demonstrators in 1819. Shelley's epic poem, The Mask of Anarchy, reflected the widespread public outrage and condemnation of the government's role in the massacre. Why did a peaceful and orderly meeting of men, women and children in St Peter's Field, Manchester turn into a blood bath? How were the stirrings of radicalism in the wake of the Napoleonic Wars dealt with by the British establishment? And what role did the Peterloo Massacre play in bringing about the Great Reform Act of 1832? With Jeremy Black, Professor of History at the University of Exeter; Sarah Richardson, Senior Lecturer in History at the University of Warwick; Clive Emsley, Professor of History at the Open University.

Melvyn Bragg and guests discuss artificial intelligence. Can machines think? It was a question posed by the mathematician and Bletchley Park code breaker Alan Turing and it is a question still being asked today. What is the difference between men and machines and what does it mean to be human? And if we can answer that question, is it possible to build a computer that can imitate the human mind? There are those who have always had robust answers to the questions that those who seek to create artificial intelligence have posed. In 1949 the eminent neurosurgeon, Professor Geoffrey Jefferson argued that the mechanical mind could never rival a human intelligence because it could never be conscious of what it did: "Not until a machine can write a sonnet or compose a concerto because of thoughts and emotions felt", he declared "and not by the chance fall of symbols, could we agree that machine equals brain - that is, not only write it but know that it had written it." Yet the quest rolled on for machines that were bigger and better at processing symbols and calculating infinite permutations. Who were the early pioneers of artificial intelligence and what drove them to imitate the operations of the human mind? Is intelligence the defining characteristic of humanity? And how has the quest for artificial intelligence been driven by warfare and conflict in the twentieth century? With Jon Agar, Lecturer in the History and Philosophy of Science, University of Cambridge; Alison Adam, Professor of Information Systems, Salford University; Igor Aleksander, Professor of Neural Systems Engineering at Imperial College, University of London.

Melvyn Bragg and guests discuss the great 17th century political philosopher Thomas Hobbes who argued: "During the time men live without a common power to keep them all in awe, they are in that condition which is called war; and such a war as is of every man against every man". For Hobbes, the difference between order and disorder was stark. In the state of nature, ungoverned man lived life in "continual fear, and danger of violent death". The only way out of this "solitary, poor, nasty, brutish, and short" existence, he said, was to relinquish all your freedom and submit yourself to one all powerful absolute sovereign. Hobbes' proposal, contained in his controversial and now classic text, Leviathan, was written just as England was readjusting to life after the Civil War and the rule of Oliver Cromwell. In fact, in his long life Hobbes’ allegiance switched from Charles I to Cromwell and back to Charles II. But how did the son of a poor clergyman end up as the most radical thinker of his day? Why did so many of Hobbes' ideas run counter to the prevailing fondness for constitutionalism with a limited monarchy? And why is he regarded by so many political philosophers as an important theorist when so few find his ideas convincing? With Quentin Skinner, Regius Professor of History at the University of Cambridge; David Wootton, Professor of History at the University of York; Annabel Brett, Senior Lecturer in Political Thought and Intellectual History at Cambridge University.

Melvyn Bragg and guests discuss the search for the Graviton particle. Albert Einstein said "I know why there are so many people who love chopping wood. In this activity one immediately sees the results". Einstein spent the last thirty years of his life trying to find a theory that would unify electromagnetism with gravity, but success eluded him. The search is still on for a unifying theory of gravitational force and hopes are pinned on the location of the graviton - a hypothetical elementary particle that transmits the force of gravity. But the graviton is proving hard to find. Indeed, the Large Hadron Collider at CERN still won't allow us to detect gravitons per se, but might be able to prove their existence in other ways. The idea of the graviton particle first emerged in the middle of the 20th century, when the notion that particles as mediators of force was taken seriously. Physicists believed that it could be applicable to gravity and by the late 20th century the hunt was truly on for the ultimate theory, a theory of quantum gravity. So why is the search for the graviton the major goal of theoretical physics? How will the measurement of gravitation waves help prove its existence? And how might the graviton unite the seemingly incompatible theories of general relativity and quantum mechanics? With Roger Cashmore, Former Research Director at CERN and Principal of Brasenose College, Oxford; Jim Al-Khalili, Professor of Physics at the University of Surrey; Sheila Rowan, Reader in Physics in the Department of Physics and Astronomy at the University of Glasgow.

Melvyn Bragg and guests discuss the American philosophy of pragmatism. A pragmatist "turns away from abstraction and insufficiency, from verbal solutions, from bad apriori reasons, from fixed principles, closed systems, and pretended absolutes and origins. He turns towards concreteness and adequacy, towards facts, towards action and towards power". A quote from William James' 1907 treatise Pragmatism: A New Name for Some Old Ways of Thinking. William James, along with John Dewey and Charles Sanders Peirce, was the founder of an American philosophical movement which flowered during the last thirty years of the nineteenth century and the first twenty years of the 20th century. It purported that knowledge is only meaningful when coupled with action. Nothing is true or false - it either works or it doesn't. It was a philosophy which was deeply embedded in the reality of life, concerned firstly with the individual's direct experience of the world he inhabited. In essence, practical application was all. But how did Pragmatism harness the huge scientific leap forward that had come with Charles Darwin's ideas on evolution? And how did this dynamic new philosophy challenge the doubts expressed by the Sceptics about the nature and extent of knowledge? Did Pragmatism influence the economic and political ascendancy of America in the early 20th century? And did it also pave the way for the contemporary preoccupation with post-modernism? With A C Grayling, Professor of Applied Philosophy at Birkbeck College, University of London and a Fellow of St Anne's College, Oxford; Julian Baggini, editor of The Philosophers' Magazine; Miranda Fricker, Lecturer in Philosophy at Birkbeck College, University of London.

Melvyn Bragg and guests discuss the religious orders of the Dominicans and the Franciscans, known as the Blackfriars and Greyfriars. "Just as it is better to light up others than to shine alone, it is better to share the fruits of one's contemplation with others than to contemplate in solitude". Thus St Thomas Aquinas described his vocation, not only as a teacher, but also as a Dominican friar and philosopher at the University of Paris. In the 13th century, the religious orders of the Dominicans and the Franciscans were a great force for change in Catholic Europe. They thrived in the emerging towns and cities of the High Middle Ages, leading crusades and changing the way the Church dealt with heretics. They were the evangelists who transformed the Church's preaching of the Christian message to the people. On top of all this, these two orders were also responsible for reconciling Classical and Christian philosophy; their studies of Aristotle paved the way for the Renaissance. They also managed to change the curriculum at the universities of Paris and Oxford. But the Blackfriars and the Greyfriars did not come from the great monasteries of the time; they started out as itinerant preachers surviving upon the charity of the faithful. So how did these two orders come to dominate the spiritual and academic life of the 13th century, and how did they manage to accumulate such huge wealth while professing allegiance to lives of poverty? With Henrietta Leyser, medieval historian and Fellow of St Peter's College, Oxford; Alexander Murray, medieval historian and Emeritus Fellow of University College, Oxford; Anthony Kenny, philosopher and former Master of Balliol College, Oxford.

Melvyn Bragg and guests discuss the unique properties of asteroids. They used to be regarded as the 'vermin of the solar system', irritating rubble that got in the way of astronomers trying to study more interesting phenomena. It was difficult or even impossible for an observer of asteroids to book time using the world's best telescopes, because they were regarded as unspectacular objects that could tell us little about the origins of the universe. However, that has all changed. It is now thought that asteroids are the unused building blocks of planets, 'pristine material' that has remained chemically unchanged since the creation of the solar system; a snapshot of matter at the beginning of time. At the moment the Japanese probe Hayabusa is 180 million miles away, pinned to the back of the asteroid Itokawa, attempting to gain our first samples of the chemical composition of an asteroid. Why did asteroids fail to form planets? How do they differ from their celestial cousins, the comets? And are either of them likely to create another impact on planet Earth? With Monica Grady, Professor of Planetary and Space Sciences, Open University; Carolin Crawford, Royal Society Research Fellow, University of Cambridge; John Zarnecki, Professor of Space Science, Open University.

Melvyn Bragg and guests discuss Samuel Johnson, a giant of 18th century literature. “There is no arguing with Johnson, for when his pistol misses fire, he knocks you down with the butt of it." The poet Oliver Goldsmith was not alone in falling victim to the bludgeoning wit of Samuel Johnson. The greatest luminaries of 18th century England, including the painter Joshua Reynolds, the philosopher Edmund Burke and the politician Charles James Fox, all deferred to him... happily or otherwise. Samuel Johnson was credited with defining English literature with his Lives of the Poets and his edition of Shakespeare, and of defining English language with his Dictionary. Yet despite those lofty acclamations he failed to get a degree, claimed he had never finished a book, was an inveterate hack who told his friend James Boswell, "No man but a blockhead ever wrote, except for money". How did an Oxford drop-out become England's most famous and well connected man of letters? How did generations of readers come to see him as the father of English Literature? And why is he so little read today? With John Mullan, Professor of English at University College London; Jim McLaverty, Professor of English at Keele University; Judith Hawley, Senior Lecturer in English at Royal Holloway, University of London.

Melvyn Bragg and guests discuss the Cynics, the performance artists of philosophy. Eating live octopus with fresh lupins, performing intimate acts in public places and shouting at passers by from inside a barrel is behaviour not normally associated with philosophy. But the Cynics were different. They were determined to expose the meaninglessness of civilised life by action as well as by word. They slept rough, ate simply and gave their lectures in the market place. Perhaps surprisingly, their ideas and attitudes were immensely popular in the ancient world. But how coherent was cynicism as a philosophy? What was its influence on literature and politics and is there any truth to the contention that Jesus himself was influenced by the Cynics? With Angie Hobbs, Lecturer in Philosophy, University of Warwick; Miriam Griffin, Fellow of Somerville College, Oxford; John Moles, Professor of Latin, University of Newcastle.

Melvyn Bragg and guests discuss the rise of the mammals. The Cenozoic Era of Earth's history began 65 million years ago and runs to this day. It began with the extraordinary 'KT event', a supposed asteroid impact that destroyed the dinosaurs, and incorporates the break up of Pangaea, the enormous landmass that eventually formed the continents we know today. It is known as the 'Age of the Mammals', and it is the period in which warm-blooded, lactating, often furry animals diversified rapidly and spread across the globe on land and in the sea. According to evolutionary theory, what conditions created the opportunity for mammals to thrive? What environmental factors lead to the characteristics they share - and the features they don't? And how did they become the most intelligent class of animals on the planet? With Richard Corfield, Senior Lecturer in Earth Sciences at the Open University; Steve Jones, Professor of Genetics at University College London; Jane Francis, Professor of Palaeoclimatology at the University of Leeds.

Melvyn Bragg and guests discuss the Field of the Cloth of Gold, an extraordinary international party. In the spring of 1520 six thousand Englishmen and women packed their bags and followed their King across the sea to France. They weren't part of an invasion force but were attendants to King Henry VIII and travelling to take part in the greatest and most conspicuous display of wealth and culture that Europe had ever seen. They were met by Francis I of France and six thousand French noblemen and servants on English soil in Northern France and erected their temporary palaces, elaborate tents, jousting pavilions and golden fountains spewing forth red, white and claret wine in the Val D'Or. For just over two weeks they created a temporary town the size of Norwich, England's second city, on the 'Camp du Drap D'Or', or Field of the Cloth of Gold. What drove the French and the English to create such an extraordinary event? What did the two sides do when they got there, and what - if anything - was achieved? With Steven Gunn, Lecturer in Modern History at Oxford University; John Guy, Fellow of Clare College, University of Cambridge; Penny Roberts, Senior Lecturer in History at the University of Warwick.

Melvyn Bragg and guests discuss the history of magnetism. Pliny the Elder, in his Historia Naturalis, tells a story of a legendary Greek shepherd called Magnes who, while guiding his flock on Mount Ida, suddenly found it hard to move his feet. The nails of his sandals held fast to the rock beneath them, and the iron tip of his crook was strangely attracted to the boulders all around. Magnes had stumbled across the lodestone, or 'Magnetite', and discovered the phenomenon of magnetism. Plato was baffled by this strange force, as were Aristotle and Galen, and despite being used in navigation, supposedly suspended over the body of Mohammed and deployed in the pursuit of medical cures. St Thomas Aquinas thought magnets had souls. it was not until the late 16th century that any serious scientific attempt was made to explain the mystifying powers of the magnet. Descartes developed a particle theory of magnetism but the great Isaac Newton fought shy of the problem of what caused magnets to attract and repelWho pioneered the study of magnetism? What theories did they construct from its curious abilities and how was the power of the magnet brought out of the realm of magic and into the service of science? With Stephen Pumfrey, Senior Lecturer in the History of Science at the University of Lancaster; John Heilbron, Emeritus Professor of History at the University of California, Berkeley; Lisa Jardine, Professor of Renaissance Studies at Queen Mary, University of London.

Melvyn Bragg and guests discuss Karl Marx. "Workers of the World Unite! You have nothing to lose but your chains", "Religion is the opium of the people", and "From each according to his abilities, to each according to his needs". That should be enough for most of you to work out whom Radio 4 listeners have voted as their favourite philosopher: the winner of the In Our Time Greatest Philosopher Vote, chosen from 20 philosophers nominated by listeners and carried through on an electoral tidal wave of 28% of our 'first-past-the-post' vote is the communist theoretician, Karl Marx.So, when you strip away the Marxist-Leninism, the Soviet era and later Marxist theory, who was Karl Marx? Where does he stand in the history of philosophy? He wrote in his Theses on Feuerbach, "Philosophers have only interpreted the world in various ways, the point, however, is to change it" - which begs the question, is he really a philosopher at all?With Anthony Grayling, Professor of Philosophy at Birkbeck College, University of London; Francis Wheen, journalist and author of a biography of Karl Marx; Gareth Stedman Jones, Professor of Political Science at Cambridge University.

Melvyn Bragg and guests discuss Christopher Marlowe. In the prologue to The Jew of Malta Christopher Marlowe has Machiavel say:"I count religion but a childish toy, And hold there is no sin but ignorance. Birds of the air will tell of murders past! I am ashamed to hear such fooleries.Many will talk of title to a crown. What right had Caesar to the empire? Might first made kings, and laws were then most sure When, like the Draco's, they were writ in blood."A forger, a brawler, a spy, a homosexual and accused of atheism but above all a playwright and poet, Christopher Marlowe was the most celebrated writer of his generation, bringing Tamburlaine, Faustus and The Jew of Malta to the stage and far outshining William Shakespeare during his lifetime. Then came his mysterious death at 29, days before he was due to appear on trial accused of heresy. Was he stabbed in an argument over a bill? Was he assassinated? And how does his work measure up to Shakespeare, a man who paid generous tribute and some say stole some of his best lines? Was Marlowe assassinated by the Elizabethan state? How subversive was his literary work? And had he lived as long as his contemporary Shakespeare, how would he have compared?With Katherine Duncan-Jones, Senior Research Fellow in the English Faculty of Oxford University; Jonathan Bate, Professor of English Literature, University of Warwick; Emma Smith, Lecturer in English, Oxford University.

Melvyn Bragg and guests discuss the legendary wizard Merlin. He was sired by an incubus and born of a virgin; he was a prophet, a shape-shifter, a king-maker and a mad man of the woods. Before Gandalf there was Merlin: the power behind Arthur and a literary sensation for centuries. In a literary career spanning 1500 years, Merlin, or originally Myrddin, put the sword in the stone, built Stonehenge, knew the truth behind the Holy Grail and discovered the Elixir of Life. "Beware Merlin for he knows all things by the devil's craft" say the poisoners in Malory's Morte D'Arthur; but he is also on the side of the good and is almost Christ-like in some of the versions of his tale, and his prophesies were pored over by the medieval Church. Who was Merlinus Ambrosius, as he is sometimes known? Where does his legend spring from and how has it been appropriated and adapted over time?With Juliette Wood, Associate Lecturer in the Department of Welsh at Cardiff University, Stephen Knight, Distinguished Research Professor in English Literature at Cardiff University, Peter Forshaw, Lecturer in Renaissance Philosophies at Birkbeck, University of London.

Melvyn Bragg and guests discuss the KT Boundary. Across the entire planet, where it hasn't been eroded or destroyed in land movements, there is a thin grey line. In Italy it is 1 cm thick, in America it stretches to three centimetres, but it is all the same thin grey line laid into the rock some 65 million years ago and it bears witness to a cataclysmic event experienced only once in Earth's history. It is called the KT Boundary and geologists believe it is the clue to the death of the dinosaurs and the ultimate reason why mammals and humans inherited the Earth.But exactly what did happen 65 million years ago? How was this extraordinary line created across the Earth and does it really hold the key to the death of the dinosaurs?With Simon Kelley, Head of Department in the Department of Earth Sciences, Open University, Jane Francis, Professor of Palaeoclimatology, University of Leeds; Mike Benton, Professor of Vertebrate Palaeontology in the Department of Earth Sciences, University of Bristol.

Melvyn Bragg and guests discuss paganism in the Renaissance. For hundreds of years in the Middle Ages, the only way to read Ovid was through the prism of a Christian moralising text. Ovid's sensual tales of metamorphosis and pagan gods were presented as veiled allegories, and the famous story of Zeus descending to Danae in a shower of gold was explained as the soul receiving divine illumination. But in 1478 Botticelli finished Primavera, the first major project on a mythological theme for a thousand years, and by 1554 Titian completed a very different version of Danae - commissioned by a Cardinal, no less - where she expectantly awaits her union with Zeus in what is a nakedly sexual pose. What happened to bring the myths and eroticism of antiquity back into the culture of Europe? And how was it possible for a Church that was prosecuting for heresy, to exalt in pagan imagery, even in the Vatican itself?With Tom Healy, Professor of Renaissance Studies, Birkbeck College, University of London; Charles Hope, Director of the Warburg Institute and Professor of the History of the Classical Tradition, University of London; Evelyn Welch, Professor of Renaissance Studies at Queen Mary, University of London.

Melvyn Bragg and guests discuss the Scriblerus Club. The 18th century Club included some of the most extraordinary and vivid satirists ever to have written in the English language. We are given giants and midgets, implausible unions with Siamese twins, diving competitions into the open sewer of Fleet-ditch, and Olympic-style pissing competitions: "Who best can send on high/The salient spout, far streaming to the sky". But these exotic images were part of an attempt by Pope, Swift and their cadres to show a world in terrible decline: "Religion, blushing, veils her sacred fires,And unawares Morality expires.Nor public flame, nor private dares to shine;Nor human spark is left, nor glimpse divine!Lo! Thy dread empire, Chaos! Is restored:Light dies before thy uncreating word".So wrote Alexander Pope in his great mock epic verse, The Dunciad. Who were the Scriblerans? And what in eighteenth century society had driven them to such disdain and despair?With John Mullan, Senior Lecturer in English, University College London; Judith Hawley, Senior Lecturer in English, Royal Holloway, University of London; Marcus Walsh, Kenneth Allott Professor of English Literature, University of Liverpool.

Melvyn Bragg and guests discuss Renaissance Mathematics. As with so many areas of European thought, mathematics in the Renaissance was a question of recovering and, if you were very lucky, improving upon Greek ideas. The geometry of Euclid, Appollonius and Ptolemy ruled the day. Yet within two hundred years, European mathematics went from being an art that would unmask the eternal shapes of geometry to a science that could track the manifold movements and changes of the real world. The Arabic tradition of Algebra was also assimilated. In its course it changed the way people understood numbers, movement, time, even nature itself and culminated in the calculus of Isaac Newton and Gottfried Leibniz. But how did this profound change come about? What were the ideas that drove it and is this the period in which mathematics became truly modern?With Robert Kaplan, co-founder of the Maths Circle at Harvard University; Jim Bennett, Director of the Museum of Science and Fellow of Linacre College, University of Oxford; Jackie Stedall, Research Fellow in the History of Mathematics, The Queen's College, Oxford.

Melvyn Bragg and guests discuss the reign of terror during the French Revolution. On Monday September 10th 1792 The Times of London carried a story covering events in revolutionary France: "The streets of Paris, strewed with the carcases of the mangled victims, are become so familiar to the sight, that they are passed by and trod on without any particular notice. The mob think no more of killing a fellow-creature, who is not even an object of suspicion, than wanton boys would of killing a cat or a dog". These were the infamous September Massacres when Parisian mobs killed thousands of suspected royalists and set the scene for the events to come, when Madame La Guillotine took centre stage and The Terror ruled in France. But how did the French Revolution descend into such extremes of violence? Who or what drove The Terror? And was it really an aberration of the revolutionary cause or the moment when it truly expressed itself? With Mike Broers, Lecturer in Modern History at the University of Oxford and Fellow of Lady Margaret Hall; Rebecca Spang, Lecturer in Modern History at University College London; Tim Blanning, Professor of Modern European History at the University of Cambridge.

Melvyn Bragg and guests discuss beauty and its qualities."Beauty is truth, truth beauty, - that is all Ye know on earth, and all ye need to know."That was John Keats' emphatic finale to his Ode on a Grecian Urn. It seems to express Plato's theory of aesthetics, his idea that an apprehension of beauty is an apprehension of perfection and that all things in our shadowy realm are botched representations of perfect 'forms' that exist elsewhere. Beauty is goodness and, for Plato, the ultimate of all the forms is 'The Good'.But does beauty really have a moral quality? And is it inherent in things, or in the mind of the observer? How much influence have Plato's ideas had on the history of aesthetics and what has been said to counter or develop them?With Angie Hobbs, Lecturer in Philosophy at the University of Warwick; Susan James, Professor of Philosophy at Birkbeck College, University of London; Julian Baggini, Editor of The Philosophers' Magazine.

Melvyn Bragg and guests discuss the story of Abelard and Heloise, a tale of literature and philosophy, theology and scandal, and above all love in the high Middle Ages. They were two of the greatest minds of their time and Abelard, a famous priest and teacher, wrote of how their affair began in his biography, Historia Calamitatum, “Her studies allowed us to withdraw in private, as love desired, and then with our books open before us, more words of love than of reading passed between us, and more kissing than teaching. My hands strayed oftener to her bosom than to the pages; love drew our eyes to look on each other more than reading kept them on our texts”. Years later, when she was an Abbess at the head of her own convent, Heloise wrote to Abelard: “Even during the celebration of Mass, when our prayers should be purer, lewd visions of those pleasures take such a hold upon my unhappy soul that my thoughts are on their wantonness instead of on prayers”. With Anthony Grayling, Professor of Philosophy at Birkbeck College, University of London; Henrietta Leyser, Medieval Historian and Fellow of St Peter’s College, Oxford; Michael Clanchy, Emeritus Professor of Medieval History at the Institute of Historical Research.

Melvyn Bragg and guests discuss perception: how the brain reacts to the mass of data continually crowding it. Barry Stein's laboratory at Wake Forest University in the United States found that the shape of a right angle drawn on the hand of a chimpanzee starts the visual part of the brain working, even when the shape has not been seen. It has also been discovered that babies learn by touch before they can properly make sense of visual data, and that the senses of smell and taste chemically combine to give us flavour.Perception is a tangled web of processes and so much of what we see, hear and touch is determined by our own expectations that it raises the question of whether we ever truly perceive what others do.What governs our perception of the world? And are we correct to distinguish between sight, sound, smell, touch and taste when they appear to influence each other so very much?With Richard Gregory, Senior Research Fellow in the Department of Experimental Psychology, Bristol University; David Moore, Director of the Medical Research Council Institute of Hearing Research, University of Nottingham; Gemma Calvert, Reader in Cognitive Neuroscience, University of Bath.

Melvyn Bragg and guests discuss 'The Aeneid'. Out of the tragedy and destruction of the Trojan wars came a man heading West, his father on his back and his small son holding his hand. This isn't Odysseus, it's Aeneas and in that vision Virgil gives an image of the very first Romans of the Empire.Virgil's Aeneid was the great epic poem that formed a founding narrative of Rome. It made such an impact on its audience that it soon became a standard text in all schools and wiped away the myths that preceded it. It was written in Augustus' reign at the start of the Imperial era and has been called an apologia for Roman domination; it has also been called the greatest work of literature ever written.How much was Virgil's poem influenced by the extraordinary times in which it was written? How does it transcend the political pressures of Imperial patronage and what are the qualities that make it such a universal work?With Edith Hall, Leverhulme Professor of Greek Cultural History, Durham University; Philip Hardie, Corpus Christi Professor of Latin at the University of Oxford; Catharine Edwards, Senior Lecturer in Classics and Ancient History, Birkbeck College, University of London.

Melvyn Bragg and guests discuss the link between archaeology and imperialism. In 1842 a young English adventurer called Austen Henry Layard set out to excavate what he hoped were the remains of the biblical city of Nineveh in Mesopotamia. On arrival he discovered that the local French consul, Paul Emile Botta, was already hard at work. Across the Middle East and in Egypt, archaeologists, antiquarians and adventurers were exploring cities older than the Bible and shipping spectacular monuments down the Nile and the Tigris to burgeoning European museums.What was it about the ancient cultures of Egypt and Mesopotamia that so gripped the 19th century imagination? How did nationalism and imperialism affect the search for the ancient past and how did archaeology evolve from its adventuresome, even reckless, origins into the science of artefacts we know today?With Tim Champion, Professor of Archaeology, University of Southampton; Richard Parkinson, Assistant Keeper in the Department of Ancient Egypt and Sudan at the British Museum; Eleanor Robson, Lecturer in the History and Philosophy of Science at Cambridge University and a Fellow of All Souls College, Oxford.

Melvyn Bragg and guests discuss King Alfred and the defeat of the Vikings at Battle of Edington. At the end of the 9th century the Vikings controlled almost all of what we now call England. Mercia had fallen and its king had fled, Northumbria had fallen and so had Essex. The only independent kingdom left standing against the rampaging Danes was Wessex, and Alfred the Great; then he was overrun, his treasury, palaces and castles taken whilst he and his most loyal followers were left to wander the moors. Yet he came back. The Battle of Edington in 878 is taken by many to be the great founding Battle of England. It is the conflict in which Alfred, King of Wessex, came back to defeat the Vikings and launch a grand project to establish a new entity of Englishness, what he called the 'Anglecynn' in the South of the island of Britain.How did Alfred manage to defeat the Vikings when he had been so thoroughly routed? What motivated his project to fashion Englishness? And without Edington, would there be no England?With Richard Gameson, Reader in Medieval History, University of Kent at Canterbury; Sarah Foot, Professor of Early Medieval History, University of Sheffield; John Hines, Professor in the School of History and Archaeology, Cardiff University.

Melvyn Bragg and guests discuss the life and work of John Ruskin. He was the most brilliant art critic of his age, perhaps the most brilliant that Britain has ever produced, but he was much more than that. A champion of Turner and an enemy of Whistler, he placed the study of art and architecture at the heart of a moral assault on Victorian life. In the stone work of a Gothic cathedral, Ruskin saw all that was right about medieval society and all that was wrong about his own capitalist age.But why was Ruskin so critical of his own time? What deep currents of thought infused his ideas? And how much does our thinking, about society, the environment, art and work owe to this unusual man?With Dinah Birch, Professor of English, Liverpool University; Keith Hanley, Professor of English Literature and Director of the Ruskin Programme, Lancaster University; Stefan Collini, Professor of Intellectual History and English Literature, University of Cambridge.

Melvyn Bragg and guests discuss the heavenly host of Angels. George Bernard Shaw made the observation that "in heaven an angel is nobody in particular", but there is nothing commonplace about this description of angels from the Bible's book of Ezekiel:"They had the likeness of a man. And every one had four faces, and every one had four wings. And their feet were straight feet; and the sole of their feet was like the sole of a calf's foot: and they sparkled like the colour of burnished brass.... As for the likeness of their faces, they four had the face of a man, and the face of a lion, on the right side: and they four had the face of an ox on the left side; they four also had the face of an eagle." With angels like that, it is easy to see why they have caused so much controversy over the centuries.What part have angels played in western religion? How did they get their halos and their wings? And what are they really: Gods or men?With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Valery Rees, Renaissance Scholar at the School of Economic Science; John Haldane, Professor of Philosophy, University of St Andrews.

Melvyn Bragg and guests discuss 'dark energy'. Only 5% of our universe is composed of visible matter, stars, planets and people; something called 'dark matter' makes up about 25% and an enormous 70% of the universe is pervaded with the mysteriously named 'dark energy'. It is a recent discovery and may be only a conjecture, but it has been invoked to explain an abiding riddle of the cosmos: if the expansion of the universe is powered by the energy of the Big Bang, then why isn't the expansion slowing down over time as the initial energy runs down and the attractive force of gravity asserts itself? Scientists had predicted a Big Crunch as the logical opposite of the Big Bang, but far from retracting, the expansion of the universe is actually accelerating...it's running away with itself.How do we know that the universe is behaving like this and what's causing it? If dark energy is the culprit, then what is this elusive, though omnipresent entity?With Sir Martin Rees, Astronomer Royal and Professor of Cosmology and Astrophysics, Cambridge University; Carolin Crawford, Royal Society University Research Fellow at the Institute of Astronomy, University of Cambridge; Sir Roger Penrose, Emeritus Rouse Ball Professor of Maths at Oxford University.

Melvyn Bragg and guests discuss the mad, bad world of modern utopias. "I want to gather together about twenty souls," wrote D H Lawrence in 1915, "and sail away from this world of war and squalor and find a little colony where there shall be no money but a sort of communism as necessaries of life go, and some real decency". Utopias were in the air in the first decades of the 20th century and the literature of the period abounds with worlds of imagined escape, feminist utopias, technological nightmares and rich imaginings of the world as it could or should become. Many of the societies that writers like H G Wells created were meant seriously, as signposts to a future that would seem horrific to us now, where the weak are eradicated and the strong prosper and procreate.What was it about that era that brought forward so many imagined futures? How did utopias become the dystopias of Brave New World and 1984, and why are writers so much less likely to create a Utopia now?With John Carey, Emeritus Professor of English Literature, Oxford University and editor of The Faber Book of Utopias; Steve Connor, Professor of Modern Literature at Birkbeck, University of London; Laura Marcus, Professor of English, University of Sussex.

Melvyn Bragg and guests discuss Stoicism, the third great philosophy of the Ancient World. It was founded by Zeno in the fourth century BC and flourished in Greece and then in Rome. Its ideals of inner solitude, forbearance in adversity and the acceptance of fate won many brilliant adherents and made it the dominant philosophy across the whole of the Ancient World. The ex-slave Epictetus said "Man is troubled not by events, but by the meaning he gives them". Seneca, the politician, declared that "Life without the courage for death is slavery". The stoic thoughts of Marcus Aurelius, the philosopher emperor, provided a rallying point for empire builders into the modern age.Stoicism influenced the Christian church, had a big effect on Shakespeare and Renaissance drama and may even have given the British their 'stiff upper lip', but it's a philosophy that was almost forgotten in the 20th century. Does it still have a legacy for us today?With Angie Hobbs, Lecturer in Philosophy, University of Warwick; Jonathan Rée, philosopher and historian; David Sedley, Laurence Professor of Ancient Philosophy, University of Cambridge.

Melvyn Bragg and guests discuss the history of Alchemy, the ancient science of transformations. The most famous alchemical text is the Emerald Tablet, written around 500BC and attributed to the mythical Egyptian figure of Hermes Trismegistus. Among its twelve lines are the essential words - “as above, so below". They capture the essence of alchemy, that the heavens mirror the earth and that all things correspond to one another. Alchemy was taken up by some of the most extraordinary people in our intellectual development, including Roger Bacon, Paracelsus, the father of chemistry, Robert Boyle, and, most famously, Isaac Newton, who wrote more about alchemy than he did about physics. It is now contended that it was Newton’s studies into alchemy which gave him the fundamental insight into the famous three laws of motion and gravity.With Peter Forshaw, Lecturer in Renaissance Philosophies at Birkbeck, University of London, Lauren Kassell, Lecturer in the History and Philosophy of Science at the University of Cambridge, Stephen Pumfrey, Senior Lecturer in the History of Science at the University of Lancaster.

Melvyn Bragg and guests discuss the Cambrian period when there was an explosion of life on Earth. In the Selkirk Mountains of British Columbia in Canada, there is an outcrop of limestone shot through with a seam of fine dark shale. A sudden mudslide into shallow water some 550 million years ago means that a startling array of wonderful organisms has been preserved within it. Wide eyed creatures with tentacles below and spines on their backs, things like flattened rolls of carpet with a set of teeth at one end, squids with big lobster-like arms. There are thousands of them and they seem to testify to a time when evolution took a leap and life on this planet suddenly went from being small, simple and fairly rare to being large, complex, numerous and dizzyingly diverse. It happened in the Cambrian Period and it's known as the Cambrian Explosion.But if this is the great crucible of life on Earth, what could have caused it? How do the strange creatures relate to life as we see it now? And what does the Cambrian Explosion tell us about the nature of evolution?With Simon Conway Morris, Professor of Evolutionary Palaeobiology, Cambridge University; Richard Corfield, Visiting Senior Lecturer at the Centre for Earth, Planetary, Space and Astronomical Research, Open University; Jane Francis, Professor of Palaeoclimatology, University of Leeds.
