In Our Time

Melvyn Bragg and guests Usha Goswami, Annette Karmiloff-Smith and Denis Mareschal discuss what new research reveals about the infant brain.For obvious reasons, what happens in the minds of very young, pre-verbal children is elusive. But over the last century, the psychology of early childhood has become a major subject of study. Some scientists and researchers have argued that children develop skills only gradually, others that many of our mental attributes are innate. Sigmund Freud concluded that infants didn't differentiate themselves from their environment. The pioneering Swiss child psychologist Jean Piaget thought babies' perception of the world began as a 'blooming, buzzing confusion' of colour, light and sound, before they developed a more sophisticated worldview, first through the senses and later through symbol. More recent scholars such as the leading American theoretical linguist Noam Chomsky have argued that the fundamentals of language are there from birth. Chomsky has famously argued that all humans have an innate, universally applicable grammar.Over the last ten to twenty years, new research has shed fresh light on important aspects of the infant brain which have long been shrouded in mystery or mired in dispute, from the way we start to learn to speak to the earliest understanding that other people have their own minds.

Melvyn Bragg and guests Justin Champion, Susan Hardman Moore and Diarmaid MacCulloch discuss the ideas of the religious reformer John Calvin - the theology known as Calvinism, or Reformed Protestantism - and its impact. John Calvin, a Frenchman exiled to Geneva, became a towering figure of the 16th century Reformation of the Christian Church. He achieved this not through charismatic oratory, but through the relentless rigour of his analysis of the Bible. In Geneva, he oversaw an austere, theocratic and sometimes brutal regime. Nonetheless, the explosion of printing made his theology highly mobile. The zeal he instilled in his followers, and the persecution which dogged them, rapidly spread the faith across Europe, and on to the New World in America. One of Calvin's most striking tenets was 'predestination': the idea that, even before the world began, God had already decided which human beings would be damned, and which saved. The hope of being one of the saved gave Calvinists a driving energy which has made their faith a galvanic force in the world, from business to politics. Anxiety about salvation, meanwhile, led to a constant introspection which has left its mark on literature.Justin Champion is Professor of the History of Early Modern Ideas at Royal Holloway, University of London; Susan Hardman Moore is Senior Lecturer in Divinity at the University of Edinburgh; Diarmaid MacCulloch, Professor of the History of the Church at the University of Oxford.

Melvyn Bragg and guests Faisal Devji, Shruti Kapila and Chandrika Kaul discuss the Indian Mutiny of 1857 and the rebellion which followed.On 10th May 1857 Indian soldiers from the Bengal section of the East India Company's army rose up and shot their British officers. By nightfall the troops had marched on Delhi and the aged Mughal emperor Bahadur Shah II had been nominally restored to power. Nearly 15 months later, after great violence on both sides, the revolt was suppressed, but it left British rule in India transformed and, arguably, doomed.The trigger for the Mutiny was a rumour that cartridges for the new British rifles were coated with pig and cow fat, thereby insulting both Hindu and Muslim troops. But the Indian Rebellion was also a more complex story of economic strains, religious insensitivity and well-intentioned but provocative liberal reforms.The events of 1857 have resonated through history and have been appropriated and mythologised by the British press and Indian nationalists alike. However, the shocking violence of the Rebellion on both sides has meant that it has defied attempts to fit it into a coherent narrative structure. It has overshadowed British foreign policy and Indian politics ever since.Chandrika Kaul is Lecturer in Imperial and Indian History at the University of St Andrews; Faisal Devji is University Reader in Indian History at St Antony's College, University of Oxford; Shruti Kapila is University Lecturer in History and Fellow and Director of Studies at Corpus Christi College, University of Cambridge.

Melvyn Bragg and guests John Barrow, Colva Roney-Dougal and Marcus du Sautoy explore the unintended consequences of mathematical discoveries, from the computer to online encryption, to alternating current and predicting the path of asteroids.In his book The Mathematician's Apology (1941), the Cambridge mathematician GH Hardy expressed his reverence for pure maths, and celebrated its uselessness in the real world. Yet one of the branches of pure mathematics in which Hardy excelled was number theory, and it was this field which played a major role in the work of his younger colleague, Alan Turing, as he worked first to crack Nazi codes at Bletchley Park and then on one of the first computers.Melvyn Bragg and guests explore the many surprising and completely unintended uses to which mathematical discoveries have been put. These include:The cubic equations which led, after 400 years, to the development of alternating current - and the electric chair.The centuries-old work on games of chance which eventually contributed to the birth of population statistics.The discovery of non-Euclidean geometry, which crucially provided an 'off-the-shelf' solution which helped Albert Einstein forge his theory of relativity.The 17th-century theorem which became the basis for credit card encryption.In the light of these stories, Melvyn and his guests discuss how and why pure mathematics has had such a range of unintended consequences.John Barrow is Professor of Mathematical Sciences at the University of Cambridge and Professor of Geometry at Gresham College, London; Colva Roney-Dougal is Lecturer in Pure Mathematics at the University of St Andrews; Marcus du Sautoy is Charles Simonyi Professor for the Public Understanding of Science and Professor of Mathematics at the University of Oxford.

Melvyn Bragg and guests Robert Hoyland, Robert Irwin and Hugh Kennedy discuss the life and ideas of the 14th-century Arab philosopher of history Ibn Khaldun.Ibn Khaldun was a North African statesman who retreated into the desert in 1375. He emerged having written one of the most important ever studies of the workings of history.Khaldun was born in Tunis in 1332. He received a supremely good education, but at 16 lost many of his family to the Black Death. His adult life was similarly characterised by sharp turns of fortune. He built a career as a political operator in cities from Fez to Granada. But he often fared badly in court intrigues, was imprisoned and failed to prevent the murder of a fellow statesman. In 1375, he withdrew into the Sahara to work out why the Muslim world had degenerated into division and decline. Four years later, he had completed not only a history of North African politics but also, in the book's long introduction, one of the great studies of history. Drawing on both regional history and personal experience, he set out a bleak analysis of the rise and fall of dynasties. He argued that group solidarity was vital to success in power. Within five generations, though, this always decayed. Tired urban dynasties inevitably became vulnerable to overthrow by rural insurgents.Later in life, Ibn Khaldun worked as a judge in Egypt, and in 1401 he met the terrifying Mongol conqueror Tamburlaine, whose triumphs, Ibn Khaldun felt, bore out his pessimistic theories.Over the last three centuries Ibn Khaldun has been rediscovered as a profoundly prescient political scientist, philosopher of history and forerunner of sociology - one of the great thinkers of the Muslim world.Robert Hoyland is Professor of Islamic History at the University of Oxford; Robert Irwin is Senior Research Associate of the School of Oriental and African Studies at the University of London; Hugh Kennedy is Professor of Arabic in the School of Oriental and African Studies at the University of London.

Melvyn Bragg and guests Rosemary Ashton, Dinah Birch and Valentine Cunningham discuss George Eliot's novel Silas Marner.Published in 1861, Silas Marner is by far Eliot's shortest and seemingly simplest work. Yet beneath the fairytale-like structure, of all her novels it offers the most focused expression of Eliot's moral view. Influenced by the deconstruction of Christianity pioneered by leading European thinkers including Auguste Comte and Ludwig Feuerbach, Silas Marner is a highly sophisticated attempt to translate the symbolism of religion into purely human terms.The novel tells the story of Silas, a weaver who is thrown out of his religious community after being falsely charged with theft. Silas is embittered and exists only for his work and his precious hoard of money - until that money is stolen, and an abandoned child wanders into his house.By the end of her lifetime, George Eliot was the most powerful female intellectual in the country. Her extraordinary range of publications encompassed novels, poetry, literary criticism, scientific and religious texts. But beneath her fierce intellecualism was the deep convinction that for society to continue, humans must connect with their fellow humans. And it is this idea that forms the core of her writing.Rosemary Ashton is Quain Professor of English Language and Literature at University College, London; Dinah Birch is Professor of English at Liverpool University; And Valentine Cunningham is Professor of English Language and Literature at Corpus Christi, University of Oxford.

Melvyn Bragg and guests Karin Bowie, Murray Pittock and Daniel Szechi discuss the Glencoe Massacre of 1692, why it happened, and its lasting repercussions.On a winter night in 1692, a company of soldiers quartered with the MacDonalds of Glencoe rose early and slaughtered their hosts. About 38 men, women and children were killed. Their homes were torched and many survivors died as they fled into the snow. This mass killing was branded by a Scottish Parliamentary Commission of Inquiry as 'murder under trust'.Why did this still infamous atrocity happen? The answer takes in the seismic impact of the Glorious Revolution of 1688 and the ongoing struggles for religious power that swept through the country in the 17th century. Crucially, Britain was at war in Europe, and the distracting nature of the conflict in Scotland, as far as the London government was concerned, helped to give the events at Glencoe their particular character. But this is also a story of a deadline and the fatal consequences of the Glencoe MacDonalds' attempts to meet it - and of how their technical failure to do so was exploited.The Glencoe Massacre had a severe impact on the reputation of the government of the Protestant King William III, who had ousted the Catholic James II with the support of the English and Scottish Parliaments only four years earlier. Some historians contend that it pushed the two states along the road to the Act of Union of 1707.

Melvyn Bragg and guests Raymond Geuss, Esther Leslie and Jonathan Rée discuss the Frankfurt School.This group of influential left-wing German thinkers set out, in the wake of Germany's defeat in the First World War, to investigate why their country had not had a revolution, despite the apparently revolutionary conditions that spread through Germany in the wake of the 1918 Armistice. To find out why the German workers had not flocked to the Red Flag, Theodor Adorno, Max Horkheimer, Walter Benjamin and others came together around an Institute set up at Frankfurt University and began to focus their critical attention not on the economy, but on culture, asking how it affected people's political outlook and activities. But then, with the rise of the Nazis, they found themselves fleeing to 1940s California. There, their disenchantment with American popular culture combined with their experiences of the turmoil of the interwar years to produce their distinctive, pessimistic worldview. With the defeat of Nazism, they returned to Germany to try to make sense of the route their native country had taken into darkness. In the 1960s, the Frankfurt School's argument - that most of culture helps to keep its audience compliant with capitalism - had an explosive impact. Arguably, it remains influential today.Raymond Geuss is a professor in the Faculty of Philosophy at the University of Cambridge; Esther Leslie is Professor in Political Aesthetics at Birkbeck College, University of London; Jonathan Rée is a freelance historian and philosopher, currently Visiting Professor at Roehampton University and at the Royal College of Art.

As part of the BBC's year of science programming, Melvyn Bragg looks at the history of the oldest scientific learned society of them all: the Royal Society. The horrors of the First World War were a shocking indictment of the power of science. Picking up the thread at this hiatus in scientific optimism, this programme, recorded in the current home of the Royal Society in Carlton House Terrace in London, looks at the more subtle, discreet role the Society played in the 20th century, such as secretly arranging for refugee scientists to flee Germany, co-ordinating international scientific missions during the Cold War and quietly distributing government grant money to fund the brightest young researchers in the land. As ever more important scientific issues face the world and Britain today, the programme asks how well placed the Royal Society is to take an important lead in the future.

As part of the BBC's year of science programming, Melvyn Bragg looks at the history of the oldest scientific learned society of them all: the Royal Society. The 19th century blooms scientifically with numerous alternative, specialist learned societies and associations, all threatening the Royal Society's pre-eminence. Attempts to reform the membership criteria - marking scientific leadership's painful transition from patronage to expertise - are troubled, and organisations such as the British Association for the Advancement of Science (now the BSA) excite and enliven scientific discourse outside of London. Science becomes a realistic career and a path of improvement, and by the time HG Wells writes science fiction at the end of the 19th century, there are sufficient numbers of interested, informed readers to suggest that Edwardian society contained the beginnings of a scientific society.
