Learning to read permanently alters your brain. It changes the emotions you experience and the way you relate to others. When a society learns to read the consequences are dramatic: wars break out, revolutions erupt and new political systems spring into being. Reading made us who we are. With time spent reading - and even reading ability - starting to nosedive, Times writer James Marriott explores how reading changed humanity, and what might happen if we stop.In this episode James digs into the question of whether literacy led to the invention of democracy, asks whether reading helps us proof ourselves against misinformation, and asks what happens to our politics if reading dies out?

Reading seems an unremarkable skill. When we say something is as “easy as ABC”, we mean it is very easy indeed. In fact, learning to read has dramatic and irreversible consequences for people and for societies. Learning to read permanently alters your brain. It changes the emotions you experience and the way you relate to others. When a society learns to read the consequences are dramatic: wars break out, revolutions erupt and new political systems spring into being. Reading made us who we are. With time spent reading - and even reading ability - starting to nosedive, Times writer James Marriott explores how reading changed humanity, and what might happen if we stop.In this programme, James asks whether the spread of novel reading in the 18th century caused a moral revolution, whether a book played a role in the abolition of slavery, and whether the rise of reading, a solitary and slightly lonely activity, was one of the factors setting us on the path to our atomized and isolated modern society.

Reading seems an unremarkable skill. After all, everyone can read. Even small children. When we say something is as “easy as ABC”, we mean it is very easy indeed. In fact, learning to read has dramatic and irreversible consequences for people and for societies. Learning to read permanently alters your brain. It changes the emotions you experience and the way you relate to others. When a society learns to read the consequences are dramatic: wars break out, revolutions erupt and new political systems spring into being. Reading made us who we are. For centuries people have been reading more and more. Recently the trend has gone into reverse. The number of people who pick up a book has been falling steadily for twenty years. Now half of adults no longer read regularly. How will this change us? Over three episodes, Times writer James Marriott explores how reading made us, and what might happen if we stop.In this first programme, James finds out how unnatural the process of reading is, and the complex alchemy our brains create to make words on the page make sense to us, and asks what we gain - and lose - when we learn to read.Guests include:- Professor Maryanne Wolf, Director of the Center for Dyslexia, Diverse Learners, and Social Justice at UCLA - John Burn-Murdoch, chief data reporter for the Financial Times - Naomi Alderman, writer and presenter - Dr Joseph Henrich, Professor of Anthropology at Harvard UniversityProducer - Beth Sagar-Fenton Editor - Chris Ledgard

The story of how reading made us and what might happen if we stop - with James Marriott.

As James Naughtie concludes his series about the ideas tying America's birth 250 years ago to the United States today, he examines freedom, asking whose freedom, and what kind?He begins in Gettysburg, attending a re-enactment on the battlefield made famous by an address from President Abraham Lincoln in which he asked whether the United States "could long endure". That question is being asked again now, as Americans experience profound disagreements over many of the ideas in this series - economic opportunity, justice, freedom; even what it means to be an American. As he hears, American history itself has become a battlefield. And so speaking to historians with different perspectives, and senior political leaders from both parties, James assesses how dangerous this moment is for United States.Producer: Giles Edwards

James Naughtie continues his look at the ideas tying America's founding to the modern United States, asking how 'justice' has been understood by different generations of Americans.In this third episode, James travels to Alabama in the American South, to understand how the Civil Rights movement sought to connect American reality with the promises in its founding documents. He hears from people in Texas on both sides of the debate about abortion, revealing how a movement built to oppose abortion rights brought millions of Christians into politics and dramatically shifted the politics of America's highest court. And in Midwestern Wisconsin, he hears how political division has come to the administration of justice itself.Producer: Giles Edwards

James Naughtie continues his look at the ideas tying America's founding to the modern United States, as he looks at what it means to be an American.In Chicago, he joins the Columbus Day parade - an exuberant celebration of Italian-American identity - and hears about the Great Migration of African Americans from the South to northern cities like Chicago. In Wisconsin, he visits the birthplace of the Republican Party, and in Ohio the Governor shows him the spot where Abraham Lincoln heard he had been formally confirmed as President-Elect. James considers how the social movements of the 1960s moved the centre of gravity of American politics from economic to social issues, with all that meant for political polarisation.Producer: Giles Edwards

James Naughtie examines the ideas tying America's founding to the modern United States.In this major new series marking America's 250th anniversary, James travels through time and across the landscape to discover how the Declaration of Independence embedded the idea of a country founded on what its authors described as 'self-evident' truths – that everyone’s inalienable rights included ‘life, liberty and the pursuit of happiness.’ In this first episode James begins with the 'pursuit of happiness' – the American search for opportunity. He begins on the site of the original gold rush in northern California, before journeying to farms and factories; small towns and big cities across the American Midwest. As he does, he reveals how from Thomas Jefferson, author of the Declaration of Independence, to President Ronald Reagan in the 1980s, Americans have always seen the connection between economic and democratic freedom - the ability to choose their own fates, and the fate of the country.

Over five episodes he and his guests look at how America’s approach to the world has constantly changed over time.

During the early weeks of the pandemic, Tim Hayward spent 14 days in a coma. He remembers this time vividly – his days and nights filled with strange, incandescent visions and hallucinations. That experience is something he would never choose to revisit but, around the world, large numbers of people are deliberately seeking out powerfully altered states.In this ten-part series, Tim sets out to better understand a group of substances that induce altered states: psychedelics.There’s been a surge of interest in their therapeutic potential for various mental health conditions - as well as a range of other clinical possibilities. As research around the world ramps up after years of taboo and prohibition he tries to get to grips with - or at least get a clearer sense of - how science, culture, politics and business might all interact in this changing psychedelic landscape, and what it all might mean.He also explores what might be happening in the brain during a trip and whether, by studying psychedelics, we might uncover more about consciousness, imagination and even the mysteries of reality itself.In this final episode, Tim explores how much there is still to understand about the therapeutic possibilities of psychedelics and, furthermore, what other insights research might lead us towards. Will curious minds be given the space to roam free?

From the “dawn” of psychedelic science in 1799 through to prohibition in the second half of the last century, Tim explores shifting cultural and scientific approaches to substances that induce altered states. There had been a willingness to openly explore the trip experience and to see what might be discovered by doing so.
