The Reith Lectures

The inaugural Reith Lecturer is the philosopher, mathematician, and social reformer Bertrand Russell. One of the founders of analytic philosophy and a Nobel Laureate, Russell's pupils included Wittgenstein, and his most influential work, Principia Mathematica, set out to show how mathematics was grounded in logic. He also wrote On Denoting, one of the most significant philosophical essays of the 20th century, and the bestselling History of Western Philosophy, written in 1946. His Reith lecture series is entitled 'Authority and the Individual'.

In his first lecture, entitled 'Social Cohesion and Human Nature', Russell explores the role of impulses in human nature. He charts the way these impulses have manifested themselves throughout history, from very primitive communities through to more 'civilised' societies.

Deepfakes, distrust and democracy: Billions of people will have the chance to vote this year in elections around the world. There will be campaigns in eight of the 10 most populous countries, including India and the Biden/Trump race for the White House in the US. Given the stakes, the chance for AI shenanigans is high. Sam Altman, founder of ChatGPT, has warned “of a new kind of interference that was just not possible before AI.”

It raises two basic questions: How that might work? And, what might it mean? For answers, Katya speaks with leading experts in AI and democracy, each of whom have delivered the prestigious BBC Reith Lectures:

- Stuart Russell, Professor of Computer Science and founder of the Centre for Human-Compatible Artificial Intelligence at the University of California, Berkeley

- Ben Ansell, Professor of Comparative Democratic Institutions at Nuffield College, Oxford University

This year's BBC Reith Lecturer is Ben Ansell, Professor of Comparative Democratic Institutions at Nuffield College, Oxford University and author of “Why Politics Fails.” In four lectures called “Our Democratic Future,” he asks how we can build a politics that works for all of us with political systems which are robust to the challenges of the twenty first century, from climate change to artificial intelligence.

In this fourth and final lecture, recorded in Atlanta, Georgia in the United States, he interrogates a crucial question: can we continue to grow our economies without despoiling the earth? Focusing on the existential threats created by our own innovation - from climate change to out-of-control artificial intelligence – Ansell asks whether our politics is up to the task of supporting sustainable growth.

The Reith Lectures are chaired by Anita Anand and produced by Jim Frank. The Editors are China Collins and Clare Fordham, and the co-ordinator is Brenda Brown. The series is mixed by Rod Farquhar and Neil Churchill.

He will deliver four lectures in a series called “Our Democratic Future.” The series asks how we can build a politics that works for all of us with systems which are robust to the challenges of the twenty first century, from climate change to artificial intelligence. In this third lecture, recorded in Sunderland, Professor Ansell explores whether we can develop a shared sense of belonging in today's polarised societies. How can we ensure that we look after the less fortunate in an economy that seems only to reward the 'already haves'? Ansell addresses the challenges posed by technologies that enrich a small elite and privatise solidarity with bespoke healthcare and benefits that might undermine collective solidarity. And he assesses how policy reform - from universal basic income to civic nationalism - might help renew our communities.

In his series Professor Ansell asks how we can build a politics that works for all of us with systems which are robust to the challenges of the twenty first century, from climate change to artificial intelligence. The lectures build on his recent book Why Politics Fails, which identifies a series of traps that prevent us from attaining our collective goals and presents solutions to help us overcome those traps.

In this second lecture called 'The Future of Security', recorded in Berlin in front of an audience, he asks whether citizens of wealthy countries have been lulled into a false sense of security about threats from abroad and at home. It examines how we can control the security technologies of tomorrow, from facial recognition to autonomous weapons. And Ansell suggests how we can develop technologies powerful enough to protect us without exploiting us. The Reith Lectures are chaired by Anita Anand and produced by Jim Frank.

In this first lecture, recorded at New Broadcasting House in London in front of an audience, Professor Ansell asks whether we are in a 'democratic recession', where longstanding democracies are at risk of breakdown and authoritarianism is resurgent. And he examines how resilient democracies are to the challenges of artificial intelligence, social media and if they can effectively address core challenges from climate change to inequality.

In the last in a series of four lectures examining what freedom means, the foreign affairs and intelligence expert Dr Fiona Hill gives her BBC Reith Lecture on Freedom from Fear. Dr Hill is one of the world’s leading experts on Russia, and served as director for European and Russian affairs on President Trump’s National Security Council, and in senior intelligence roles for both Presidents Bush and Obama. She will talk about the fear she felt growing up as teenager in the Cold War and living with the threat of nuclear war. Then, she says, the culture of fear was about the Soviet Union, a largely unknown enemy. 40 years later, have we come full circle? She also analyses Russia's war in Ukraine, and what it means for the world.

Author and musician Darren McGarvey gives the third of four BBC Reith Lectures on the theme of liberty, addressing "Freedom from Want." McGarvey argues that the present system isn't working for many but that it is incumbent on citizens to confront that and rise to the challenge of what inequality means. Individuals, he says, need to take personal responsibility and reject the apathy which many working-class communities experience.

Rowan Williams, the former Archbishop of Canterbury, gives the second of the 2022 Reith Lectures, discussing faith and liberty. In his lecture, he cites Lord Acton, the 19th Century thinker on freedom, who said that religious freedom is the basis of all political freedom. Williams addresses this with reference to South Africa and today's controversies around the abortion debate. He argues that for religious believers, freedom of worship must mean the freedom to express conviction, not just the freedom to meet.

Producer: Jim Frank Sound Engineers: Rod Farquhar and Neil Churchill Production Coordinators: Brenda Brown Editor: Hugh Levinson

Best-selling Nigerian author Chimamanda Ngozi Adichie gives the first of four 2022 Reith Lectures, discussing freedom of speech. She argues that it feels like freedom of speech is under attack. Cancel culture, arguments about “wokeness" and the assault on Salman Rushdie have produced a febrile atmosphere. Meanwhile autocrats and populists have undermined the very notion of an accepted fact-based truth which lives above politics. So how do we calibrate freedom in this context? If we have the freedom to offend, where do we draw the line? This lecture and question-and-answer session is recorded in London in front of an audience and presented by Anita Anand.

Stuart Russell suggests a way forward for human control over super-powerful artificial intelligence. He argues for the abandonment of the current “standard model” of AI, proposing instead a new model based on three principles - chief among them the idea that machines should know that they don’t know what humans’ true objectives are. Echoes of the new model are already found in phenomena as diverse as menus, market research, and democracy. Machines designed according to the new model would be, Russell suggests, deferential to humans, cautious and minimally invasive in their behaviour and, crucially, willing to be switched off. He will conclude by exploring further the consequences of success in AI for our future as a species.

Stuart Russell is Professor of Computer Science and founder of the Center for Human-Compatible Artificial Intelligence at the University of California, Berkeley.

The programme and question-and-answer session was recorded at the National Innovation Centre for Data in Newcastle Upon Tyne. Presenter: Anita Anand Producer: Jim Frank Production Coordinator: Brenda Brown Editor: Hugh Levinson.

Professor Stuart Russell explores the future of work and one of the most concerning issues raised by Artificial Intelligence: the threat to jobs. How will the economy adapt as work is increasingly done by machines? Economists’ forecasts range from rosy scenarios of human-AI teamwork, to dystopian visions in which most people are excluded from the economy altogether. Was the economist Keynes correct when he said that we were born to “strive”? If much of the work in future will be carried out by machines, what does that mean for humans? What will we do?

Stuart Russell warns of the dangers of developing autonomous weapon systems - arguing for a system of global control. Weapons that locate, select, and engage human targets without human supervision are already available for use in warfare,. Some argue that AI will reduce collateral damage and civilian casualties. Others believe it could kill on a scale not seen since Hiroshima and Nagasaki. Will future wars be fought entirely by machines, or will one side surrender only when its real losses, military or civilian, become unacceptable? Professor Russell will examine the motivation of major powers developing these types of weapons, the morality of creating algorithms that decide to kill humans, and possible ways forward for the international community as it struggles with these questions.

Stuart Russell explores the future of Artificial Intelligence and asks; how can we get our relationship with it right? Professor Russell is founder of the Centre for Human-Compatible Artificial Intelligence at the University of California, Berkeley. In this lecture he reflects on the birth of AI, tracing our thinking about it back to Aristotle. He outlines the definition of AI, its successes and failures, and the risks it poses for the future. Referencing the representation of AI systems in film and popular culture, Professor Russell will examine whether our fears are well founded. He will explain what led him – alongside previous Reith Lecturer Professor Stephen Hawking to say that “success would be the biggest event in human history … and perhaps the last event in human history.” Stuart will ask how this risk arises and whether it can be avoided, allowing humanity and AI to coexist successfully.

Mark Carney, the former Governor of the Bank of England, argues that the roots of the climate change threat lie in a deeper crisis of values. He suggests that we can create an ecosystem in which society’s values broaden the market’s conceptions of value. In this way, individual creativity and market dynamism can be channelled to achieve broader social goals including, inclusive growth and environmental sustainability.

Presenter: Anita Anand Producer: Jim Frank Editor: Hugh Levinson Production Coordinator: Brenda Brown Studio Manager: Rod Farquhar

Mark Carney, the former Governor of the Bank of England, observes that the pandemic has forced states to confront how we value health, wealth and opportunity. During the first few months of the crisis, most states chose to value human life more than the economic well-being of the nation-state. But if that seems to be changing how do we assess value in this sense?

Dr Carney elucidates surprising differences in the financial value put on a human life in different nations – and goes on to argue that this reductionist approach fails to take into account deeper thinking about the worth of human existence.

Presenter: Anita Anand Producer: Jim Frank Editor: Hugh Levinson

Mark Carney, the former Governor of the Bank of England, takes us back to the high drama of the financial crisis of 2008, which ended a period when bankers saw themselves as unassailable Masters of the Universe. More than a decade on, how much have the bankers changed their ways? How far has the financial sector changed? Dr Carney says that we must remain vigilant and resist the “three lies of finance.” If we don’t, he warns, we will live with a system which is ill-prepared for the next crisis.

Presenter: Anita Anand Producer: Jim Frank Editor: Hugh Levinson

Mark Carney’s Reith 2020 Lectures chart how we have come to esteem financial value over human value and how we have gone from market economies to market societies. He argues that this has contributed to a trio of crises: of credit, Covid and climate. And the former Bank of England Governor will outline how we can turn this around.

In this lecture, recorded with a virtual audience, he reflects that whenever he could step back from what felt like daily crisis management, the same deeper issues loomed. What is value? How does the way we assess value both shape our values and constrain our choices? How do the valuations of markets affect the values of our society?

Dr Carney argues that society has come to embody Oscar Wilde’s aphorism: “Knowing the price of everything but the value of nothing.”

Jonathan Sumption argues against Britain adopting a written constitution as a response to political alienation. The former UK Supreme Court Justice has argued that politics is in decline partly, at least, because the courts and the law is increasingly doing what politicians used to do. This has indirectly contributed to the electorate’s increasing rejection of the political process. There is growing resentment against the political elite. So what can we do? Lord Sumption makes some suggestions to restore faith in democracy – starting by fixing the party system and changing the way we vote.

The programme is recorded in front of an audience at Cardiff University.

Editor: Hugh Levinson

Jonathan Sumption assesses the US and UK’s constitutional models. He describes Britain's unwritten constitution as a political institution. The US Constitution is by contrast essentially a legal document. This has led Americans to address what should be political questions – such as the right to abortion – via the courts, rather than through politics. Britain, Lord Sumption argues, should learn from the United States be careful about which rights should be put beyond democratic choice.

The programme is recorded in front of an audience at George Washington University in Washington DC.

Jonathan Sumption argues that judges - especially those of the European Court of Human Rights - have usurped power by expanding the interpretation of human rights law. Lord Sumption argues that concepts of human rights have a long history in the common law. But by contrast, the European Convention on Human Rights has become a dynamic treaty, taking on new interpretations and powers. Article 8 – the right to private and family life – is the most striking example. Should these decisions be made by judges or parliament? The lecture is recorded before an audience in the old Parliament House in Edinburgh.

Jonathan Sumption explains how democratic processes have the power to accommodate opposition opinions and interests. But he argues that in recent years that politics has shied away from legislating and now the courts have taken on more and more of the role of making law. Lord Sumption was until recently a justice of the UK’s Supreme Court and is a distinguished historian. This lecture is recorded in front of an audience at Birmingham University.

Jonathan Sumption argues that the law is taking over the space once occupied by politics. Lord Sumption was until recently a justice of the UK’s Supreme Court, as well as being a distinguished historian. In this lecture, recorded before an audience at Middle Temple in London, Lord Sumption says that until the 19th century, law only dealt with a narrow range of human problems. That has now changed radically. And he argues that the growth of the law, driven by demand for greater personal security and less risk, means we have less liberty.

Historian Margaret MacMillan looks at representations of war: can we really create beauty from horror and death? Speaking at the Canadian War Museum, she discusses the paradox of commemoration. She questions attempts to capture the essence and meaning of war through art. The programme is presented by Anita Anand in front of an audience and includes a question and answer session.

Historian Margaret MacMillan assesses how the law and international agreements have attempted to address conflict. Speaking to an audience at the Northern Irish Parliament Buildings at Stormont in Belfast, Professor MacMillan outlines how both states and the people have sought to justify warfare - from self-defence to civil war - focusing on examples from Irish and British history. The programme, including a question and answer session, is presented by Anita Anand.

Producer: Jim Frank Editor: Hugh Levinson

Historian Margaret MacMillan dissects the relationship between war and the civilian. Speaking to an audience in Beirut, she looks back at the city's violent past and discusses the impact of conflict on noncombatants throughout the centuries. She explores how civilians have been deliberately targeted, used as slaves and why women are still often singled out in mass rapes. And she addresses the proposition that human beings are becoming less, not more violent. The programme is chaired by Anita Anand.

Producer: Jim Frank Editor: Hugh Levinson

Historian Margaret MacMillan asks why both men and women go to war. "We are both fascinated and repulsed by war and those who fight," she says. In this lecture, recorded at York University, she explores looks at the role of the warrior in history and culture and analyses how warriors are produced. And she interrogates the differences that gender plays in war. Anita Anand presents the programme recorded in front of an audience, including a question and answer session.

Producer: Jim Frank Editor: Hugh Levinson

Is war an essential part of being human? Are we destined to fight? That is the central question that historian Professor Margaret Macmillan addresses in five lectures recorded in the UK, Lebanon and in Canada. In her series, called The Mark of Cain, she will explore the tangled history of war and society and our complicated feelings towards it and towards those who fight.

She begins by asking when wars first broke out. Did they start with the appearance of homo sapiens, or when human beings first organised themselves into larger groupings such as tribes, clans, or nations? She assesses how wars bring about change in society and, conversely, how social and political change influences how wars start and are fought. And she discusses that dark paradox of war: that it can bring benefits and progress.

The programme is recorded before an audience at the BBC Radio Theatre in London and includes a question and answer session chaired by Anita Anand.

Margaret MacMillan is emeritus professor of international history at Oxford University and professor of history at the University of Toronto. She says: "We like to think of war as an aberration, as the breakdown of the normal state of peace. This is comforting but wrong. War is deeply woven into the history of human society. Wherever we look in the past, no matter where or how far back we go, groups of people have organised themselves to protect their own territory or ways of life and, often, to attack those of others. Over the centuries we have deplored the results and struggled to tame war, even abolish it, while we have also venerated the warrior and talked of the nobility and grandeur of war. We all, as human beings, have something to say about war."

Professor Angela Stent examines the lessons to be learnt from the 1957 Reith Lectures by the legendary American diplomat George Kennan, titled "Russia, the Atom and the West". Kennan, the architect of the American post-war policy of containment of the Soviet Union, was a key player during the Cold War. Stent, the former National Intelligence Officer for Russia and Eurasia at the US National Intelligence Council, evaluates the continuing relevance of the lectures, in conversation with Sarah Montague.

The series assesses the contributions of great minds of the past to public debate, in a dialogue across the decades with contemporary thinkers. In 1948, households across Britain gathered before the wireless as the pre-eminent public intellectual of the age, the philosopher Bertrand Russell delivered a set of lectures in honour of the BBC's founder, Lord Reith. Since then, the Reith Lectures on the Home Service and subsequently Radio 4 have become a major national occasion for intellectual debate.

Hilary Mantel on how fiction changes when adapted for stage or screen. Each medium, she says, draws a different potential from the original. She argues that fiction, if written well, doesn't betray history, but enhances it. When fiction is turned into theatre, or into a film or TV, the same applies - as long as we understand that adaptation is not a secondary process or a set of grudging compromises, but an act of creation in itself. And this matters. "Without art, what have you to inform you about the past?" she asks. "What lies beyond is the unedited flicker of closed-circuit TV."

The programme is recorded in Stratford-Upon-Avon in front of an audience, with a question and answer session, chaired by Sue Lawley. The producer is Jim Frank.

Hilary Mantel analyses how historical fiction can make the past come to life. She says her task is to take history out of the archive and relocate it in a body. "It's the novelist's job: to put the reader in the moment, even if the moment is 500 years ago." She takes apart the practical job of "resurrection", and the process that gets historical fiction on to the page. "The historian will always wonder why you left certain things out, while the literary critic will wonder why you left them in," she says. How then does she try and get the balance right?

The lecture is recorded in front of an audience in Exeter, near Mantel's adopted home in East Devon, followed by a question and answer session. The Reith Lectures are chaired by Sue Lawley and produced by Jim Frank.

The story of how an obsessive relationship with history killed the young Polish writer Stanislawa Przybyszewska, told by best-selling author, Hilary Mantel. The brilliant Przybyszewska wrote gargantuan plays and novels about the French Revolution, in particular about the revolutionary leader Robespierre. She lived in self-willed poverty and isolation and died unknown in 1934. But her work, so painfully achieved, did survive her. Was her sacrifice worthwhile? "She embodied the past until her body ceased to be," Dame Hilary says. "Multiple causes of death were recorded, but actually she died of Robespierre."

Over the course of these five lectures, she discusses the role that history plays in our lives. How do we view the past, she asks, and what is our relationship with the dead? The lecture is recorded before an audience in the ancient Vleeshuis in Antwerp, a city which features in Mantel's novels about Thomas Cromwell and the cosmopolitan world of the early Tudors. The lecture is followed by a question and answer session chaired by Sue Lawley.

The producer is Jim Frank.

How do we construct our pictures of the past, including both truth and myth, asks best-selling author Hilary Mantel. Where do we get our evidence? She warns of two familiar errors: either romanticising the past, or seeing it as a gory horror-show. It is tempting, but often condescending, to seek modern parallels for historical events. "Are we looking into the past, or looking into a mirror?" she asks. "Dead strangers...did not live and die so we could draw lessons from them." Above all, she says, we must all try to respect the past amid all its strangeness and complexity.

Over the course of the lecture series, Dame Hilary discusses the role that history plays in our culture. She asks how we view the past and what our relationship is with the dead.

The programme is recorded in front of an audience at Middle Temple in London, followed by a question and answer session.

The Reith Lectures are chaired by Sue Lawley and produced by Jim Frank.

Art can bring the dead back to life, argues the late novelist Hilary Mantel, starting with the story of her own great-grandmother. 'We sense the dead have a vital force still,' she says. 'They have something to tell us, something we need to understand. Using fiction and drama, we try to gain that understanding.' She describes how and why she began to write fiction about the past, and how her view of her trade has evolved. We cannot hear or see the past, she says, but 'we can listen and look'.

This was the first of a series of five lectures recorded in 2017, in which Dame Hilary discussed the role that history plays in our culture. How can we understand the past, she asks, and how can we convey its nature today? Above all, she believed, we must all try to respect the past amid all its strangeness and complexity.

This lecture is being rebroadcast as a tribute to Dame Hilary. It was recorded in front of an audience at Halle St Peter's in Manchester, followed by a question and answer session chaired by Sue Lawley.

The philosopher and cultural theorist Kwame Anthony Appiah says the idea of "Western civilization" or "Western culture" is a mistaken one and that we should abandon it.

He uncovers the history of the idea from its roots at the time of the Crusades to its modern incarnation in the second half of the 20th century. However, we have very little culturally in common with our forebears in say the England of Chaucer's time. And indeed much of the knowledge supposedly at the heart of Western civilisation was actually transmitted via Islamic scholarship. No-one, he argues, can claim exclusive ownership of culture. "The values European humanists like to espouse belong just as easily to an African or an Asian who takes them up with enthusiasm as to a European," he says.

The lecture is recorded in front of an audience at New York University in Appiah's adopted home city. The series is presented and chaired by Sue Lawley

The producer is Jim Frank.

The philosopher and cultural theorist Kwame Anthony Appiah argues for a world free of racial fixations.

He tells the story of Anton Wilhelm Amo Afer. He was five years old when he was brought from the Gold Coast to Germany in 1707, educated at a royal court and became an eminent philosopher. He argues that this elaborate Enlightenment experiment illuminates a series of mistaken ideas , including that there is a "racial essence" which all members of that race carry. Modern science long ago disproved this, as almost all of the world's genetic variation is found within every so-called racial group. Instead, "race is something we make; not something that makes us."

The philosopher and cultural theorist Kwame Anthony Appiah argues against a mythical, romantic view of nationhood, saying instead it should rest on a commitment to shared values.

He explores the history of the idea, born in the 19th century, that there are peoples who are bound together by an ancient common spirit and that each of these nations is entitled to its own state. He says this idea is a mistaken one, illustrating his argument through the life story of the writer who took the pen name Italo Svevo - meaning literally Italian Swabian. He was born a citizen of the Austro-Hungarian Empire and became a citizen of the new republic of Italy, all without leaving his home city of Trieste. Appiah argues that states exist as a set of shared beliefs rather than membership of some sort of mythical and ancient group. "What binds citizens together is a commitment," he says, "to sharing the life of a modern state, united by its institutions, procedures and precepts."

Philosopher and cultural theorist Kwame Anthony Appiah argues that when considering religion we overestimate the importance of scripture and underestimate the importance of practice.

He begins with the complexities of his own background, as the son of an English Anglican mother and a Ghanaian Methodist father. He turns to the idea that religious faith is based around unchanging and unchangeable holy scriptures. He argues that over the millennia religious practice has been quite as important as religious writings. He provides examples from Jewish, Christian, Islamic and Buddhist texts to show that they are often contradictory and have been interpreted in different ways at different times, for example on the position of women and men in Islam. He argues that fundamentalists are a particularly extreme example of this mistaken scriptural determinism.

The lecture is recorded in front of audience at the London School of Economics and Political Science. The series is presented and chaired by Sue Lawley. Future lectures will examine identity in the contexts of country, colour and culture.

The Cambridge cosmologist Professor Stephen Hawking delivers the second of his BBC Reith Lectures on black holes.

Professor Hawking examines scientific thinking about black holes and challenges the idea that all matter and information is destroyed irretrievably within them. He explains his own hypothesis that black holes may emit a form of radiation, now known as Hawking Radiation. He discusses the search for mini black holes, noting that so far "no-one has found any, which is a pity because if they had, I would have got a Nobel Prize." And he advances a theory that information may remain stored within black holes in a scrambled form.

The programmes are recorded in front of an audience of Radio 4 listeners and some of the country's leading scientists at the Royal Institution of Great Britain in London.

Sue Lawley introduces the evening and chairs a question-and-answer session with Professor Hawking. Radio 4 listeners submitted questions in their hundreds, of which a selection were invited to attend the event to put their questions in person to Professor Hawking.

Professor Stephen Hawking delivers the first of his two BBC Reith Lectures on black holes.

These collapsed stars challenge the very nature of space and time, as they contain a singularity - a phenomenon where the normal rules of the universe break down. They have held an enduring fascination for Professor Hawking throughout his life. Rather than see them as a scary, destructive and dark he says if properly understood, they could unlock the deepest secrets of the cosmos.

Professor Hawking describes the history of scientific thinking about black holes, and explains how they have posed tough challenges to conventional understanding of the laws which govern the universe.

The surgeon and writer Atul Gawande calls for a new focus on medical systems to ensure doctors work more effectively, alongside far greater transparency about their performance.

Speaking to an audience at the India International Centre in Delhi, he describes the story of medicine over the last century through the prism of his own family. From a grandmother who died in rural India from malaria - a preventable disease - to the high-tech medicine of today. He argues that despite its scientific advances, medicine has failed to exploit its knowledge successfully. In both the developed and developing world doctors do not carry out basic procedures effectively and often do not act in the best interests of their patients. He calls for wide-ranging research into the systems by which medical care is delivered, alongside far greater transparency about performance.

The Reith Lectures are introduced and chaired by Sue Lawley and produced by Jim Frank.

Surgeon and writer Atul Gawande calls for a new approach to the two great unfixable problems in life and healthcare - ageing and death. He tells the story of how his daughter's piano teacher faced up to terminal cancer and the crucial choices she made about how to spend her final days. He says the teacher was only able to do this because of an essential honesty from her physicians and the people around her. Dr. Gawande argues that the common reluctance of society and medical institutions to recognise the limits of what professionals can do can end up increasing the suffering of patients towards the end of life. He proposes that both doctors and individuals ask a series of simple but penetrating questions to decide what kind of treatment is appropriate - or whether treatment is appropriate at all. And he praises the values of the hospice movement, in putting quality of life before prolonging life.

The programme was recorded at The Royal Society in Edinburgh in front of an audience.

The Reith Lectures are introduced and chaired by Sue Lawley and produced by Jim Frank.

The surgeon and writer Atul Gawande argues that better systems can transform global healthcare by radically reducing the chance of mistakes and increasing the chance of successful outcomes.

He tells the story of how a little-known hospital in Austria managed to develop a complex yet highly effective system for dealing with victims of drowning. He says that the lesson from this dramatic narrative is that effective systems can provide major improvements in success rates for surgery and other medical procedures. Even a simple checklist - of the kind routinely used in the aviation industry - can be remarkably effective. And he argues that these systems have the power to transform care from the richest parts of the world to the poorest.

The programme was recorded at The Wellcome Collection in London before an audience.

The Reith Lectures are chaired and introduced by Sue Lawley and produced by Jim Frank.

Surgeon and writer Atul Gawande explores the nature of fallibility and suggests that preventing avoidable mistakes is a key challenge for the future of medicine.

Through the story of a life-threatening condition which affected his own baby son, Dr. Gawande suggests that the medical profession needs to understand how best to deploy the enormous arsenal of knowledge which it has acquired. And his challenge for global health is to address the inequalities in access to resources and expertise both within and between countries.

This first of four lectures was recorded before an audience at the John F Kennedy Presidential Library and Museum in Dr. Gawande's home town of Boston in Massachusetts. The other lectures are recorded in London, Edinburgh and Delhi.

In the last of his four Reith Lectures, recorded in front of an audience at Central St Martins School of Art in London, the artist Grayson Perry discusses his life in the art world; the journey from the unconscious child playing with paint, to the award-winning successful artist of today. He talks about being an outsider and how he struggles with keeping his integrity as an artist. Perry looks back and asks why men and women throughout history, despite all the various privations they suffered, have always made art. And he discusses the central purpose of creating art - to heal psychic wounds and to make meaning. Perry was awarded the Turner Prize in 2003 and is well known for his ceramic works, printmaking, drawing, sculpture and tapestry. He is also known as one of Britain's most famous cross-dressers as alter ego Claire. The Reith Lectures are presented by Sue Lawley and produced by Jim Frank.

In the third of four lectures, recorded in front of an audience at The Guildhall in Londonderry, the artist Grayson Perry asks if revolution is a defining idea in art, or has it met its end?

Perry says the world of art seems to be strongly associated with novelty. He argues that the mainstream media seems particularly drawn to the idea of there being an avant-garde: work is always described as being "cutting edge," artists are "radical," shows are "mould-breaking," ideas are "ground-breaking," "game-changing" or "revolutionary," We are forever being told that a new paradigm is being set. Perry says we have reached the final state of art. Not an end game, as there will always be great new art, but that art has lost one of its central tenets: its ability to shock. We have seen it all before.

Grayson Perry was awarded the Turner Prize in 2003 and is the first contemporary artist to deliver the Reith Lectures. He is best known for his ceramic works, print making, drawing, sculpture and tapestries as well as being a flamboyant cross-dresser.

The Reith Lectures are presented and chaired by Sue Lawley and produced by Jim Frank.

The award-winning artist Grayson Perry asks whether it is really true that anything can be art. We live in an age when many contemporary artists follow the example of Marcel Duchamp, who famously declared that a urinal was a work of art. It sometimes seems that anything qualifies, from a pile of sweets on a gallery floor to an Oscar-winning actress asleep in a box. How does the ordinary art lover decide? In a lecture delivered amidst the Victorian splendour of St. George's Hall in Liverpool, Perry analyses with characteristic wit the common tests - from commercial worth to public popularity to aesthetic value. He admits the inadequacies of such yardsticks, especially when applied to much conceptual and performance art. And he concludes that in his opinion, the quality most valued in the art world is seriousness. Producer: Jim Frank

In the first of four lectures, recorded in front of an audience at Tate Modern in London in 2013, the artist Grayson Perry reflects on the idea of quality and examines who and what defines what we see and value as art. He argues that there is no empirical way to judge quality in art. Instead the validation of quality rests in the hands of a tightknit group of people at the heart of the art world including curators, dealers, collectors and critics who decide in the end what ends up in galleries and museums. Often the last to have a say are the public. Perry examines the words and language that have developed around art critique, including what he sees as the growing tendency to over-intellectualise the response to art. He analyses the art market and quotes – with some irony – an insider who says that certain colours sell better than others. He queries whether familiarity makes us like certain artworks more, and encourages the public to learn to appreciate different forms of art through exploration and open-mindedness. Perry was awarded the Turner Prize in 2003, and is known for his ceramic works, printmaking, drawing, sculpture and tapestry as well as for his cross-dressing and alter-ego, Claire.

The historian Niall Ferguson examines institutions outside the political, economic and legal realms, whose primary purpose is to preserve and transmit particular knowledge and values. In a lecture delivered at the Royal Society of Edinburgh, he asks if the modern state is quietly killing civil society in the Western world? And what can non-Western societies do to build a vibrant civil society?

Producer: Jane Beresford.

The historian Niall Ferguson delivers a lecture at Gresham College in the heart of legal London, addressing the relationship between the nature of law and economic success. He examines the rule of law in comparative terms, asking how far the common law's claims to superiority over other systems are credible. Are we living through a time of creeping legal degeneration in the English-speaking world?

Producer: Jane Beresford.

The eminent economic historian Niall Ferguson travels to the world's financial centre to deliver a lecture at the New-York Historical Society. He reflects on the causes of the global financial crisis, and argues that many people have drawn erroneous conclusions from it about the role of regulation. Is regulation, he asks, in fact "the disease of which it purports to be the cure"? Producer: Jane Beresford.

The eminent economic historian Professor Niall Ferguson argues that institutions determine the success or failure of nations. In a lecture delivered at the London School of Economics and Political Science, he says that a society governed by abstract, impersonal rules will become richer than one ruled by personal relationships. The rule of law is crucial to the creation of a modern economy and its early adoption is the reason why Western nations grew so powerful in the modern age.

But are the institutions of the West now degenerating? Professor Ferguson asks whether the democratic system has a fatal flaw at its heart. In the West young people are confronting the fact that they must live with the huge financial debt generated by their parents, something they had no control over despite the fact that they were born into a democracy. Is there a way of restoring the compact between different generations?

Producer: Jane Beresford.

In this third and final Reith lecture the former Director General of the security service (MI5), Eliza Manningham-Buller, discusses policy priorities since 9.11. She reflects on the Arab Spring, and argues that the West's support of authoritarian regimes did, to some extent, fuel the growth of Al-Qaeda. The lecture also considers when we should talk to "terrorists".

The former Director-General of the Security Service (MI5), Eliza Manningham-Buller gives the second of her BBC Reith Lectures 2011. In this lecture called " Security" she argues that the security and intelligence services in a democracy have a good record of protecting and preserving freedom.

The former Director-General of the Security Service (MI5), Eliza Manningham-Buller gives the first of her BBC Reith Lectures 2011 called " Terror." On the tenth anniversary of the attacks on the United States on September 11th she reflects on the lasting significance of that day. Was it a "terrorist" crime, an act of war or something different?

The pro-democracy leader, Aung San Suu Kyi, examines what drives people to dissent in the second of the 2011 Reith Lecture series. 'Securing Freedom'.

Reflecting on the history of her own party, the National League for Democracy, Aung San Suu Kyi, examines the meaning of opposition and dissident. She also explains her reasons for following the path of non-violence.

The Burmese pro-democracy leader, Aung San Suu Kyi, explores what freedom means in the first of the 2011 Reith Lecture series, 'Securing Freedom'.

Reflecting on her own experience under house arrest in Burma, she explores the universal human aspiration to be free and the spirit which drives people to dissent. She also comments on the Arab Spring, comparing the event that triggered last December's revolution in Tunisia with the death of a student during a protest in Burma in 1988.

THE REITH LECTURES 2010 4. The Runaway World

In the last Reith Lecture of 2010, Martin Rees, President of the Royal Society and Astronomer Royal, explores how fast our world is moving in the 21st century. Speaking at the Open University in Milton Keynes, the home of online learning, he acknowledges how the internet and other technologies have transformed our lives. Now he calls on politicians and other authorities to provide the funding that will keep the UK among the world's front runners in scientific research and discovery. Without money and without education to attract young people into science, the UK is in danger of falling behind China and other countries in the Far East that are investing heavily in their science and technology sectors. Professor Rees ends his series of lectures evoking memories of the 'glorious' Ely Cathedral, near Cambridge, a monument built to last a thousand years. If we, like the cathedral builders, redirect our energies and focus on the long-term, he believes together we can solve the problems that face our planet, and secure its future for billions of people worldwide and for generations to come. Producer: Kirsten Lass Editor: Sue Ellis.

3. What We'll Never Know

In the third of this year's Reith Lectures, recorded at the Royal Society during its 350th anniversary year, its President Martin Rees continues to explore the challenges facing science in the 21st century. He stresses there are things that will always lie beyond our sphere of comprehension and we should accept these limits to our knowledge. On the other hand, there are things we've never even dreamt of that will one day be ours to explore and understand. The outcome of the quest for alien life will revolutionise our sense of self in the next two decades. But some things -- like travelling back in time -- will never happen.

Lecture 2: 'Surviving the Century'

In the second of this year's Reith Lectures, recorded for the first time in Wales in the National Museum Cardiff, Martin Rees, President of the Royal Society and Astronomer Royal, continues to explore the challenges facing science in the 21st century. Our planet is coming under increasing strain from climate change, population explosion and food shortages. How can we use science to help us solve the crisis that we are moving rapidly towards, as we use up our natural resources ever more quickly? Professor Rees explores the urgent need to substantially reduce our global CO2 emissions, or the atmospheric concentration will reach truly threatening levels. To do this, we need international cooperation, and global funding for clean and green technologies. He calls for the UK to keep one step ahead of other countries by developing technologies to reduce emissions, and says we should take the lead in wave and tidal energy, among other solutions. Science brings innovation but also risk, and random elements including fanatics can abuse new technologies to threaten our planet in ways we never dreamt of. The challenge, for our scientists, governments and people, is to confront the threats to our planet and find the solutions in science.

Lecture 1: ''The Scientific Citizen'

In the first of this year's Reith Lectures, entitled Scientific Horizons, Martin Rees, President of the Royal Society, Master of Trinity College and Astronomer Royal, explores the challenges facing science in the 21st century. We are increasingly turning to government and the media to explain the risks we face. But in the wake of public confusion over issues like climate change, the swine 'flu vaccine and, more recently, Iceland's volcanic ash cloud, Martin Rees calls on scientists to come forward and play a greater role in helping us understand the science that affects us all.

Professor Michael Sandel delivers four lectures about the prospects of a new politics of the common good. The series is presented and chaired by Sue Lawley.

Sandel makes the case for a moral and civic renewal in democratic politics. Recorded at George Washington University in Washington DC, he calls for a new politics of the common good and says that we need to think of ourselves as citizens, not just consumers.

Professor Michael Sandel delivers four lectures about the prospects of a new politics of the common good. The series is presented and chaired by Sue Lawley.

Recorded at the Centre for Life in Newcastle, Sandel considers how we should use our ever-increasing scientific knowledge. New genetic technologies hold great promise for treating and curing disease, but how far we should go in using them to manipulate muscles, moods and gender?

Professor Michael Sandel delivers four lectures about the prospects of a new politics of the common good. The series is presented and chaired by Sue Lawley.

Sandel considers the role of moral argument in politics. He believes that it is often not possible for government to be neutral on moral questions and calls for a more engaged civic debate about issues such as commercial surrogacy and same-sex marriage.

Michael Sandel, Harvard Professor of Government, delivers four lectures about the prospects of a new politics of the common good. The series is presented and chaired by Sue Lawley.

Sandel considers the expansion of markets and how we determine their moral limits. Should immigrants, for example, pay for citizenship? Should we pay schoolchildren for good test results, or even to read a book? He calls for a more robust public debate about such questions, as part of a 'new citizenship'.

Chinese Vistas: Jonathan Spence lectures about China.

Recorded at Lord's cricket ground.

Spence discusses how Chinese ideas of sport and athleticism have slowly evolved over the centuries, from languorous courtship and formalised martial arts to the demanding arenas of team sports and the ultimate Olympic challenges that China will controversially host in August.

Chinese Vistas: Jonathan Spence lectures about China.

Recorded at The Asia Society in New York.

Spence explores the two centuries in which the United States gradually moved from its position as a dominant beacon of freedom and democracy for China, to becoming a more demanding global rival during and since World War II. Is America right to be wary of the emerging superpower or can the two economic and military giants co-exist happily?

Jonathan Spence lectures about China.

Spence examines China's relations with the United Kingdom through three centuries of trade, warfare, unequal treaties and missionary endeavours that shaped their mutual perceptions.

Chinese Vistas: In a lecture recorded at the British Library in London, Jonathan Spence reflects on China's most enduring thinker, Confucius. Who was this man, what did he believe in, and what contemporary relevance does his message have, nearly 2,500 years after his death? The Confucian message has survived countless attacks and is being recycled by the Chinese Communist leadership today.

Jeffrey Sachs delivers the last of five lectures. He calls for a new Enlightenment to help make globalisation work for all and lays out a blueprint for global co-operation.

Jeffrey Sachs delivers the fourth of five lectures. He considers the challenges of extreme poverty and the worry of the developed world which fears for its own prosperity.

Jeffrey Sachs delivers the third of five lectures from the Earth Institute at Columbia University, New York. He talks about the need for international co-operation.

Jeffrey Sachs delivers the second lecture from the University in Beijing. He discusses China's emergence as an economic superpower and asks what this means for the challenges ahead.

Jeffrey Sachs delivers the first of five lectures, recorded at The Royal Society, London. Sachs outlines the challenges facing mankind and argues that we must adapt to the new age.

This year's lecturer is Daniel Barenboim, who has become known as one of the most versatile pianists of his generation. His skill as a conductor and a musician has led him to world recognition and the appointment as Chief Conductor for Life by the Staatskapelle Berlin. He has also won a Grammy for his recording of Wagner's Tannhäuser and received the Wilhelm Furtwängler Prize for his work with the Staatskapelle Berlin.

In his final lecture, delivered in Jerusalem's International YMCA, Daniel Barenboim discusses the power music has beyond words. Music is more than just a physical power it is also has an emotional strength. He explores the hold music has over us and the association that music can evoke. He distinguishes between the substance of music and our perceptions of it.

In his fourth Reith Lecture, delivered from Jerusalem, Daniel Barenboim talks about co-founding the West Eastern Divan Orchestra and how it represents his central belief that music has the power to bring people together. He explains how his chance meeting with the late Palestinian-born writer Edward Said attempted to changed the political and musical landscape of the Middle East by promoting music and co-operation through projects targeted at young Arabs and Israelis.

Speaking from Berlin, Daniel Barenboim argues in his third Reith Lecture that classical music is not an exclusive language. He explains that given the right attitude it can be understood by everyone and not just the musical elite. He also examines how political correctness and bad education have caused the inability to make value judgements about public standards in music appreciation.

In his second lecture, delivered from Chicago, Daniel Barenboim argues that we rarely listen to the music of our choosing and that too often we hear music which we have no control over. He argues that this unwelcome 'muzak' is largely responsible for encouraging people not just to neglect the ear but to repress it.

This year's Reith Lecturer is the distinguished engineer, Lord Broers. Alec Broers is President of the Royal Academy of Engineering and Chairman of the House of Lords Science and Technology Committee.

In his fifth and final lecture, Lord Broers explores the responsibilities of the technologist and questions their role in society. Who regulates technology? Is it up to the individual technologist or for companies, or governments to decide?

He also examines the areas where we are likely to see the most significant advances in the next decades, and asks: who will be the winners in the race to develop future technologies?

This year's Reith Lecturer is the distinguished engineer, Lord Broers. He is President of the Royal Academy of Engineering and Chairman of the House of Lords Science and Technology Committee. He was a pioneer of nanotechnology and the first person to use the scanning electron microscope for the fabrication of micro-miniature structures.

In his fourth Reith Lecture, Lord Broers examines nanotechnology - the manipulation of matter at an atomic or molecular scale. He believes it has captured the public's imagination and given rise to the full range of emotions from admiration to fear. He explores the origins of nanotechnology with its roots in electronics and uses the relationship between it and nanoscience to illustrate the more general relationship between science and technology.

This year's Reith Lecturer is the distinguished engineer, Lord Broers. He is President of the Royal Academy of Engineering and Chairman of the House of Lords Science and Technology Committee.

In his third Reith lecture Lord Broers argues that profound changes have taken place in the development of ideas and their translation in to the market place. This innovation revolution demands a new approach to research and product development.

Some argue that technology threatens our way of life and must be controlled through regulation, however, Lord Broers believes that this is rarely necessary. He argues that it is better to allow the market - and the customers - to decide whether technologies succeed or not.

This year's Reith Lecturer is the distinguished engineer, Lord Broers. He is President of the Royal Academy of Engineering and Chairman of the House of Lords Science and Technology Committee.

In the second of his Reith Lectures, Lord Broers explores the origins of modern technologies and argues that global collaboration is essential for success. He argues that advancement must take in to account, social, environmental, economic, and political factors on a world level.

Alec Broers is President of the Royal Academy of Engineering and Chairman of the House of Lords Science and Technology Committee. He was a pioneer of nanotechnology and the first person to use the scanning electron microscope for the fabrication of micro-miniature structures.

Lord Broers delivers the first of his five Reith Lectures in which he sets out his belief that technology can and should hold the key to the future. He argues that man's way of life has depended on technology since the beginning of civilization - the flint stone, the control of fire, the wheel, the printing press, but are we coping with the newest cascade of technological advances that are happening now?

Lord Broers examines the social implications of the advances and argues that it has become essential that we study their social consequences. He believes that if poverty and disease are to be alleviated and the environment sustained, then technology must be harnessed on a vast and all inclusive scale.

In his fifth and final Reith Lecture, the Nobel Laureate, playwright, poet and political activist Wole Soyinka examines the causes and impact of fanaticism.

When Osama Bin Laden declares that the world is divided between believers and non-believers, it is easy to identify the menace of the fanatical mind but, in what other company can we place George Bush when we hear him declare that 'you are either with us or you are on the side of the terrorists'? We fail at our peril to recognize a twin strain of the same fanatic spore that threatens to consume the world in its messianic fires. What could be the role of the 'invisible' religions and world views in tempering the forces that seek to dichotomise the world?

The Nobel Laureate, playwright, poet and political activist Wole Soyinka explores the notion of dignity within a climate of fear.

Even in defeat, negotiating terms of surrender, a defeated nation pleads: 'Leave us something of our dignity'. Denied this little consideration, a doomed struggle is promptly resumed. What exactly is this 'dignity' that even nations enshrine in their constitutions and Bills of Human Rights? Is it a basic core of volition? Or is it a sense of freedom? Obviously human dignity involves both, and encompasses more. No matter the mask that is worn to hide the reality of fear, dignity remains incompatible with the entry of fear into the human psyche.

In his third Reith Lecture, the Nobel Laureate, playwright, poet and political activist Wole Soyinka examines the power of political and religious rhetoric.

Between God and Nation, and Sieg Heil, a complex set of social impulses and goals are reduced to mere sound. It is a potent tool that moves to vibrate a collective chord and displace reason. A willed hypnosis substitutes for individual will and the ecstasy of losing oneself in a sound-cloned crowd drives the most ordinary person to throw away all moral code and undertake hitherto unthinkable acts. Is the language of Political Correctness aiding and abetting its proliferation?

In his second Reith Lecture, the Nobel Laureate, playwright, poet and political activist Wole Soyinka examines how difficult it can be to tell friend from foe in a climate of fear. Organisations that are set up to overthrow dictatorships can themselves turn into tyrannical regimes. Liberation movements may be forced to seek help from dangerous quarters and these days it is not just countries that control and direct the lives of their citizens.

Wole Soyinka looks at the recent history of two countries - Algeria and Nigeria - both plagued by political turmoil. He considers what has become one of the most difficult tests for democracy - when the ballot box produces 'the wrong result' - when the people vote for a party that is fundamentally opposed to democracy?

The Nigerian born writer, Wole Soyinka, is a playwright, poet and a political activist. His novel, The Man Died: The Prison Notes of Wole Soyinka, recounts his experience of his unlawful imprisonment and the effects of solitary confinement over a period of 22 months during the Nigerian Civil war. Subsequently he has been an outspoken critic of many military dictators and in 1986 was awarded the Nobel Prize for Literature.

In his first lecture, Wole Soyinka considers the changes since the Cold War, the nature of fear and its impact on individuals and society. He explores how fear is used for positive motives as well as negative and how it's changed over time. He outlines that there is a new era of fear that pre-dates the events of 11th September. Wole Soyinka explains why for him 1989 was the moment when the world first appeared to have stood still.

This year's Reith Lecturer is Vilayanur S Ramachandran, Director of the Centre for Brain and Cognition. He has lectured widely on art and visual perception of the brain and is Editor-in-chief of the Encyclopaedia of Human Behaviour. Professor Ramachandran's work has concentrated on investigating phenomena such as phantom limbs, anosognosia and anorexia nervosa.

In his final Reith Lecture, Professor Ramachandran argues that neuroscience, perhaps more than any other discipline, is capable of transforming man's understanding of himself and his place in the cosmos.

Professor Ramachandran's work has concentrated on investigating phenomena such as phantom limbs, anosognosia and anorexia nervosa.

In his third lecture, which is the most speculative one in the series of five, Professor Ramachandran takes up one of the most ancient questions in philosophy, psychology and anthropology, namely, what is art? To do this he draws on neurological case studies and works from ethology (animal behaviour) to present a new framework for understanding how the brain creates and responds to art, and uses examples from Indian art and Cubism to illustrate these ideas.

In his second Reith Lecture Professor Ramachandran examines the process we call 'seeing'; how we become consciously aware of things around us. How does the activity of the 100 billion little wisps of protoplasm - the neurons in the brain - give rise to all the richness of our conscious experience, including the 'redness' of red, the painfulness of pain or the exquisite flavour of Marmite or Vindaloo?

Professor Ramachandran begins his Reith Lecture series on 'The Emerging Mind' by arguing that scientists need no longer be afraid to ask the big questions about what it means to be human. With empirical evidence, science can now answer ancient philosophical questions about meaning and existence. By studying neurological syndromes that have been largely ignored as curiosities or mere anomalies, we can sometimes acquire novel insights into the functions of the brain. Many of the functions of the brain, he says, are best understood from an evolutionary vantage point.
