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.

This year's BBC Reith Lecturer is Ben Ansell, Professor of Comparative Democratic Institutions at Nuffield College, Oxford University and the author of "Why Politics Fails." 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. The Editor is China Collins, and the coordinator is Brenda Brown. The series is mixed by Rod Farquhar and Neil Churchill.

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.

The Reith Lectures are presented by Anita Anand and produced by Jim Frank. The Editor is China Collins. Reith Co-ordinator is Brenda Brown. The series is mixed by Rod Farquhar and Neil Churchill.

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.

The year's series was inspired by President Franklin D Roosevelt's four freedoms speech of 1941 and asks what this terrain means now.

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.

The lecture and question-and-answer session is recorded at Swansea University in front of an audience. The presenter is Anita Anand.

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?
