In Our Time

Melvyn Bragg and guests discuss the heart. Aristotle considered the heart to be the seat of thought, reason and emotion. The Roman physician Galen located the seat of the passions in the liver, the seat of reason in the brain, and considered the heart to be the seat of the emotions. It was not until the 17th century that the physician William Harvey wrote in the preface to his thesis On the Motion of the Heart and Blood in Animals, a letter addressed to King Charles I. 'The heart of animals is the foundation of their life, the sovereign of everything within them...from which all power proceeds. The King, in like manner, is the foundation of his kingdom, the sun of the world around him, the heart of the republic, the foundation whence all power, all grace doth flow'. Harvey was probably wise to address the King in this manner, for what he laid out in his groundbreaking text challenged scientific wisdom that had gone unquestioned for centuries about the true function of the heart. Organs had been seen in a hierarchical structure with the heart as the pinnacle. But Harvey transformed the metaphor into something quite different: the heart as a mechanistic pumping device. How had the Ancient Greeks and Islamic physicians understood the heart? What role did the bodily humours play in this understanding? Why has the heart always been seen as the seat of emotion and passion? And why was it that despite Harvey's discoveries about the heart and its function, this had limited implications for medical therapy and advancement?

Melvyn Bragg and guests discuss the mathematical structures that lie within the heart of music. The seventeenth century philosopher Gottfried Leibniz wrote: 'Music is the pleasure the human mind experiences from counting without being aware that it is counting'. Mathematical structures have always provided the bare bones around which musicians compose music and have been vital to the very practical considerations of performance such as fingering and tempo. But there is a more complex area in the relationship between maths and music which is to do with the physics of sound: how pitch is determined by force or weight; how the complex arrangement of notes in relation to each other produces a scale; and how frequency determines the harmonics of sound. How were mathematical formulations used to create early music? Why do we in the West hear twelve notes in the octave when the Chinese hear fifty-three? What is the mathematical sequence that produces the so-called 'golden section'? And why was there a resurgence of the use of mathematics in composition in the twentieth century? With Marcus du Sautoy, Professor of Mathematics at the University of Oxford; Robin Wilson, Professor of Pure Mathematics at the Open University; Ruth Tatlow, Lecturer in Music Theory at the University of Stockholm.

Melvyn Bragg and guests discuss the great nineteenth century political philosopher John Stuart Mill. He believed that, 'The true philosophy is the marriage of poetry and logic'. He was one of the first thinkers to argue that a social theory must engage with ideas of culture and the internal life. He used Wordsworth to inform his social theory, he was a proto feminist and his treatise On Liberty is one of the sacred texts of liberalism. J S Mill believed that action was the natural articulation of thought. He battled throughout his life for social reform and individual freedom and was hugely influential in the extension of the vote. Few modern discussions on race, birth control, the state and human rights have not been influenced by Mill's theories. How did Mill's utilitarian background shape his political ideas? Why did he think Romantic literature was significant to the rational structure of society? On what grounds did he argue for women's equality? And how did his notions of the individual become central to modern social theory? With A C Grayling, Professor of Philosophy at Birkbeck, University of London; Janet Radcliffe Richards, Reader in Bioethics at University College London; Alan Ryan, Professor of Politics at Oxford University.

Melvyn Bragg and guests discuss the literary and visual depiction of fairies, supernatural creatures that inhabit a half-way world between this one and the next.'They stole little Bridget for seven years long; When she came down again her friends were all gone. They took her lightly back, between the night and morrow; They thought that she was fast asleep, but she was dead with sorrow. They have kept her ever since deep within the lake, On a bed of flag-leaves, watching till she wake.' When the 19th century Anglo-Irish poet Richard Allingham wrote his poem The Fairies, he was replicating a belief about supernatural figures who steal children that stretched back to ancient Persian myths that date from 3000 BC. So universal is the terror of losing a child that the images of a lonely lost child and a mother who loses her child to fairies exist in civilisations everywhere. Demon Figures and Fairies have undergone a series of transformations according to their historical context, but what remains constant is their supernatural power and their association with the very human concerns of marriage, death and loss. In what way have fairies changed in guise and purpose throughout history? How did ancient fairy lore sit with the Christianity of the Middle Ages? How were fairies appropriated for the purpose of the 16th century witchcraft trials and why did fairies obsess so many Victorian artists and writers? And why is it that stories about fairies exist all over the world and what is our fascination with them?With Juliette Wood, Associate Lecturer in the Department of Welsh at Cardiff University and Secretary of the Folklore Society; Diane Purkiss, Fellow and Tutor of English at Keble College, Oxford; Nicola Bown, Lecturer in Victorian Studies at Birkbeck, University of London.

Melvyn Bragg and guests discuss the relationship between astronomy and the British Empire. The 18th century explorer and astronomer James Cook wrote: 'Ambition leads me not only farther than any other man has been before me, but as far as I think it possible for man to go'. Cook's ambition took him to the far reaches of the Pacific and led to astronomical observations which measured the distance of Venus to the Sun with unprecedented accuracy. Cook's ambition was not just personal and astronomical. It represented the colonial ambition of the British Empire which was linked inextricably with science and trade. The discoveries about the Transit of Venus, made on Cook's voyage to Tahiti, marked the beginning of a period of expansion by the British which relied on maritime navigation based on astronomical knowledge. With Simon Schaffer, Professor in History and Philosophy of Science at the University of Cambridge; Kristen Lippincott, former Director of the Royal Observatory, Greenwich; Allan Chapman, Historian of Science at the History Faculty at Oxford University.

Melvyn Bragg and guests discuss the 1851 Great Exhibition. “Its grandeur does not consist in one thing, but in the unique assemblage of all things. Whatever human industry has created you find there. It seems as if only magic could have gathered this mass of wealth from all the ends of the earth.” So wrote Charlotte Bronte in 1851 after visiting the Great Exhibition set in the vast Crystal Palace in London's Hyde Park. By the time the exhibition closed, one quarter of the entire British population had visited Crystal Palace, the first pre-fabricated building of its kind, to marvel at an extraordinary array of exhibits there. Amongst them were the biggest diamond in the world, a carriage drawn by kites, furniture made of coal, and a set of artificial teeth fitted with a swivel devise which allowed the user to yawn without displacing them. The Great Exhibition was huge in terms of the development of British manufacturing, the burgeoning of a global consumer market, the development of museums and the international standing of Britain culturally and technologically. It was also a triumph for Prince Albert and it turned a tidy profit. How did the Exhibition crystallise a particular moment in early Victorian Britain? In what way did it capitalise on the dawn of mass travel and greater levels of international co-operation? How did fears of revolutionary Europe define the policing and organisation of the event? And how far, if at all, did the Great Exhibition go in blurring class distinctions? With Jeremy Black, Professor of History at the University of Exeter; Hermione Hobhouse, Architectural Historian and Writer; Clive Emsley, Professor of History at the Open University.

Melvyn Bragg and guests discuss the search for immunisation. In 1717, Lady Mary Wortley Montagu, the wife of the British Ambassador to the Ottoman Empire, wrote a letter to her friend describing how she had witnessed the practice of smallpox inoculation in Constantinople. This involved the transfer of material from a smallpox postule into multiple cuts made in a vein. Lady Montagu had lost her brother to smallpox and was amazed that the Middle Eastern practice of inoculation rendered the fatal disease harmless. In Britain, the practice was unknown. Inoculation was an early attempt at creating immunity to disease, but was later dismissed when Edward Jenner pioneered immunisation through vaccination in 1796. Vaccination was hailed a huge success. Napoleon described it as the greatest gift to mankind, but when the British government introduced the compulsory Vaccination Act in 1853, targeted at the poor and the working class, it sparked a mass opposition movement.How did a Gloucestershire country surgeon become known as the father of vaccination? Why did the British government introduce compulsory smallpox vaccination in 1853? What were the consequences of those who opposed it? And how was the disease finally eradicated? With Nadja Durbach, Associate Professor of History at the University of Utah, Chris Dye, Co-ordinator of the World Health Organisation's work on tuberculosis epidemiology, Sanjoy Bhattacharya, Lecturer in the Wellcome Trust Centre for the History of Medicine at UCL

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
